Kneel and beg, elevator maintenance information. I have just started to contact the elevator and urg

Hehe, you can find it at the bookstore.

The problem definitely arises on the hall door:

1: The right hall door of the elevator is too large due to the gap between the eccentric wheel on the door hanging plate and the door guide rail, and the right hall door is deflected due to the guide failure when the elevator is closed, and the electromechanical interlocking contact of the hall door is not in good contact, and the elevator can not operate normally.

2: There is a foreign object stuck in the sill of the hall door slider, resulting in the deviation of the right hall door, and the door electromechanical interlocking contact is not in good contact.

3: The gap between the door leaf of the right hall door and the sill or door pillar is too small, resulting in jamming. As a result, the right hall door is skewed, and the door electromechanical interlocking contacts are not in good contact.

It must be because the door is not completely closed in place, it is recommended to play the maintenance mode on the top of the car, and use a multimeter to measure whether the two ends of the hall door switch are turned on when the door door is closed normally, and if the elevator is used for too long, the door switch may be rusty, and there is resistance, resulting in unstable signal.

This 80-point question should be answered.

The situation at the scene can be concluded that the door lock is not connected, which causes the elevator to not operate normally.

As for the lower right area of the door is not completely closed, there are several possibilities: 1. The reason why the hall door is not correct is that the eccentric wheel is not properly adjusted or the user carries the collapse of the heavy object impact, 2. There are sundries on the sill or the door head guide rail, 3. The door is not closed well, and the door slider may not be dismantled, because the door slider imitation circle is mainly to keep the hall door oriented, and then if the hall door is too light and short-term or the torque is too small, it may also be illuminated that the hall door is not closed in place.

Interrupt the above two, the door is not closed, it may not be that there is debris in the sill, if there is debris, then the door will not be A-shaped, stuck? It is estimated that it is your local dialect, pure rough hammer type, spring-type door ** to the card resistance balance? Can't run the door lock circuit is definitely not passable, as for why the door can't be closed, you have to see to know, it is recommended that you go to the top of the car to see if the screw between the door and the door is loose!

The elevator is related to daily travel, and once it fails, it will affect personal safety. How to maintain the elevator? PChouse will take you to find out.

1. Do a good job of daily inspections.

Each elevator is equipped with safety management personnel, who will inspect and record the elevator every day, and once it is found that the odor, noise, light curtain or safety touch plate failure, door opening and closing are not smooth, and other abnormalities will be reported to the maintenance for on-site inspection.

2. Professional maintenance companies should carry out routine maintenance.

There are mainly monthly elevator maintenance that will be carried out twice a month, a quarterly maintenance inspection once a quarter, and an annual maintenance once a year for 1-3 years, the focus of their detection is different, especially the maintenance to be carried out every 15 days, and it is necessary to take into account the area that will be negligent and missing during the daily inspection, weekly inspection and monthly inspection.

3. Lubrication and maintenance.

The traction wire rope is very important in the elevator components, it is a device to provide suspension for the elevator, bearing the full weight of the elevator and the passengers, and the lifting of the elevator car also depends on the friction of the traction wire rope on the wheel groove to drive. Therefore, once the traction wire rope is damaged, it will be related to the safety of human life and property, and it needs to be regularly inspected, lubricated and maintained.

Answer: The maintenance of the elevator can be divided into one-year maintenance, half-year maintenance, monthly maintenance, and weekly maintenance.

Basic requirements for elevator weekly maintenance:

1.The elevator is required to be maintained once a week, and the time is not less than two hours, and the maintenance personnel are required to maintain the person, time and elevator.

2.The following parts of the elevator should be inspected to ensure that it.

Working, clean, lubricated.

Power switch, safety switch.

The electrical components of the control cabinet main switch and limit switch are complete and undamaged, and the wiring is firm.

Check the contact between the fuse and the fuse, the contact is firm, and there should be no ignition.

Safety switches such as emergency stop, safety window, bottom of well, and limit should be in good contact, and the action should be normal and reliable. No jumping.

Traction machine: The appearance of the body should be clean and bright.

Reducer. a.The operation should be smooth and free of abnormal vibration.

b.The height of the oil level of the gearbox should be kept within the specified oil level line.

c.The oil temperature of the reducer does not exceed 85;

Motor. a.There should be no friction sound, collision sound or other noise in the operation of the motor, and if there is any abnormal sound, the ladder should be stopped to check whether there is a foreign object invading the sliding bearing, and whether the bearing is damaged.

b.The motor oil level should be near the center of the oil mirror.

c.The ambient temperature of the motor should not be higher than 40 when used, and the temperature rise should not be higher than the nameplate specified.

d.The channeling of the motor bearing is not more than 4mm

Brake. The action is stable and reliable, no slippage, and the contact surface of the brake shoe is not less than 70%.

1.The construction elevator should be frequently inspected, maintained and maintained, the transmission part should have enough lubricating oil, the wearing parts must be frequently inspected, repaired or replaced, the bolts of the machinery, especially the parts that often vibrate, such as the tower connecting bolts should be checked whether they are loose, if they are loose, they must be tightened or replaced.

2. The brakes of each mechanism should be checked and adjusted frequently to ensure that the gap between the brake pad and the brake wheel is flexible and reliable. On the friction surface, there should be no dirt, and if there is dirt, it must be washed off with gasoline or thinner.

3. The lubrication of the gearbox, gearbox, external gear and other parts and the hydraulic oil are carried out according to the requirements in the lubrication table.

4. Pay attention to check whether there are broken wires and loose strands in each part of the wire rope. If it exceeds the relevant regulations, it must be replaced immediately. The maintenance of wire rope should be strictly in accordance with the provisions of GB5144-85.

5. All open gear transmissions must have protective covers.

6. Check the connection of each part frequently, and tighten it if it is loose. The connecting bolts of the tower body should be checked for tightness when the tower body is compressed (the method of rotating arm can be used to cause the compression state), and all connecting shafts must have cotter pins and need to be fully opened.

7. Always check whether the operation of each institution is normal, whether there is noise, and if a fault is found, it must be scheduled in time to eliminate it.

8. When installing, disassembling and adjusting the slewing mechanism, it is necessary to pay attention to ensure that the center line of the slewing mechanism reducer is parallel to the center line of the gear, and its meshing surface is not less than 70%, and the meshing clearance should be suitable.

<> the regular maintenance and maintenance of elevator equipment, which can make the elevator meet and meet the standards and technical requirements of the original design and manufacturing to the greatest extent; And it can ensure the safe and reliable operation of elevator equipment, reduce the failure rate and prolong the service life of elevator equipment.

In the management of maintenance work and the application of hardware, each installation and maintenance unit should establish a complete and systematic management system and measures to ensure the quality of regular maintenance work; And continuously improve the hardware conditions, improve the efficiency, quality and user satisfaction of the maintenance work.

Establish a post responsibility system. Due to the uniqueness of the maintenance work, it is determined that it has the characteristics of large workload flexibility, the site of the maintenance work and the working time of the maintenance work are not easy to control and manage, therefore, the regular inspection, maintenance and maintenance of the corresponding maintenance ladder must be respectively responsible for the relevant personnel. In this way, it can mobilize and improve the initiative, flexibility and sense of responsibility of on-site maintenance personnel; It can also strengthen the on-site maintenance work.

At the same time, it is necessary to establish a system of regular visits to users, collection of user feedback information, and quality spot checks, supervision and management of maintenance work. After the problem is found, it should be fed back to the design and manufacturing, technology, installation and other departments in time in order to improve product quality and work; And dynamically track and deal with users' questions or complaints to improve customer satisfaction. Of course, the supervision of maintenance work is far from enough to rely on the supervision or confirmation of users.

It is necessary to take the management of regular sampling inspections by the leaders and maintenance supervisors responsible for the maintenance work, and the irregular special inspections of full-time quality inspection (acceptance) personnel. Ensure that the regular maintenance work can be carried out in strict accordance with the maintenance technical regulations, so as to effectively supervise, control and manage the regular maintenance work.

Establish a maintenance database management system. For each maintenance elevator user, user files must be established, especially for the elevator that has just been put into use, the use of the Peibu elevator and the failure of each important machine can be entered into the maintenance elevator database management system, and then classified, statistical and analyzed processing. In this way, we can find out the reasons for the high failure rate of the elevator, and then "prescribe the right medicine", continuously improve the quality of product quality and installation and maintenance work, improve the reliability of elevator equipment, and reduce the failure rate of elevators.

According to the established user profile, the use and failure of the passenger elevator, as well as the original data of maintenance work, can be accumulated. And through the statistics and analysis of these data, the factors affecting the reliability of the elevator are pretreated or replaced with wearing parts in advance; Taking proactive and preventive maintenance measures can improve the efficiency and user satisfaction of the maintenance and distribution of the town.

To really do a good job in the regular maintenance and maintenance of elevator equipment, on the one hand, we should continuously improve and improve the management and hardware; On the other hand, in terms of technology, according to the technical requirements of specific models of elevators and the specific use of elevator equipment, formulate appropriate regular cycle inspection and maintenance plans, and conscientiously implement them, so as to truly make elevator equipment through effective regular maintenance and maintenance, meet the standards and technical requirements of original design and manufacturing, and reduce the failure rate and extend the service life of elevator equipment.
