How to reset the elevator wire rope clamp

With a large wrench. Tighten a large screw to the end, then reset the electrical switch, and then send the screw off, paying attention to the position and fitting.

There is a slight difference between the rope clamps of different manufacturers, please read the instructions before resetting or adjusting.

Elevator wire rope.

As the name suggests, the elevator wire rope is the wire rope used in the elevator, the most used small manned elevator, and the elevator wire rope specifications and models in the residential area of commercial housing.

Generally, 8*19s+fc-8mm, 8*19s+fc-10mm are used. 10mm is mainly used, and 8mm is mainly auxiliary rope. The shopping mall uses a slightly larger elevator rope specification of 12mm, 13mm, shopping mall load elevator wire rope specifications are 12mm, 13mm, 16mm diameter.

Elevator wire rope safety factor.

It refers to the ratio between the minimum breaking load of a wire rope and the maximum force of the wire rope when the car equipped with rated load is docked at the lowest landing station, and the safety factor of the traction wire rope shall not be less than the following values in any case

1) 12 for traction elevators with three or more wire ropes;

2) for the traction elevator with two wire ropes is 16;

3) 12 for reel drive elevators;

Nominal diameter of wire rope.

Not less than 8mm;

The diameter of the traction wheel or pulley: should not be less than 40 times of the nominal diameter of the traction rope;

GB8903--1988 "Elevator Wire Rope" stipulates that elevator wire rope is used

6 19S+NF or 8 19S+NF wire ropes.

Performance requirements for elevator wire ropes.

Strength requirements The strength of the elevator traction wire rope is measured by the static load safety factor.

Formula: = n

where k--represents the static load coefficient;

Breaking tension of wire rope;

n--The number of wire ropes;

t - the maximum load force acting on the wire rope on the car side;

For the K static load factor, (China) passenger elevators are more than 12 (sundries elevators are greater than 10), and Japan regulations are more than 10.

Abrasion resistance. Flexibility Good flexibility reduces the stress of wire rope bending, which is conducive to prolonging the service life.

Marking method of wire rope.

8x(19)--13--1300 right hand.

The number of strands in the 8 --- rope.

The shape of the X--- rope strand is outer thick.

19) - the number of wires in the strands.

13. Nominal diameter (mm) of --- wire rope

1300--- tensile strength of wire rope.

n mm².

The right-hand cross---- wire rope is in the direction of the right cross-twisting in the rope strand or the rope strand in the rope.

Tighten the top post screw of the rope clamp to the end so that the spring compresses the effective distance, and then place the bayonet to reset it.

What model? If it's hydraulic, there's a control box with switches in it. There is also a bolt on the rope clamp, just screw it on.

Elevator wire rope method Hello dear, tools required: gas welding or blowtorch, 22 steel wire, wire cutter, guide chain, wire rope buckle, support wood square, melted babbitt melter. First of all, measure the distance between the counterweight and the punch, if it exceeds the range of 150-400 installation standard, calculate the length to be intercepted.

The maintenance personnel first drive the slow car to the top floor on the top of the car, and one person takes the safety protection equipment to jack the counterweight in the pit with sufficient strength wood or other supports, and then lifts the car with a manual chain to make the wire rope in a loose state. It must be disassembled first, the heavy side rope head combination, the screw to remove the shock absorbing spring, and then withdraw from the pit, must not disassemble the car side rope head combination, in case the wire rope weight slides to the bottom of the pit. The floor of the computer room is hygienic, and the cleaning materials are paved to prevent dust and dirt from sticking to the wire rope, and then the bright and rotten slippery wire rope is coiled.

The installation of wire rope clamps is generally used in elevators or old ladder renovation projects.

Obviously, on the counterweight system, install a set of counterweight special speed limiter and safety gear again will increase the cost more; When adopting car two-way speed limiter and two-way safety gear, due to the limitation of machine room shaft space and installation position etc., it has been difficult to realize; The way of acting on the position of the traction wheel is mostly used in machine-room-less elevators, and the application range is relatively narrow. Therefore, for the transformation of elevators, many wire rope stop methods are used, that is, rope clamps are used to achieve upward overspeed protection.

The elevator wire rope clamp belongs to the elevator safety protection device, which comprises a brake device, a cam device, a spring device, a spring compression device, a locking device, the braking device comprises a fixed brake plate and a moving brake plate, the spring compression mechanism comprises a sprocket-belt transmission device composed of a sprocket chain transmission mechanism and a winch mechanism, when the rope clamp is braked, the spring in the spring device is released from the compression state, and the spring pushes the cam follower in the cam device to drive the brake plate to move towards the fixed brake plate, Finally, the brake device clamps the wire rope; When the rope clamp is released, the sprocket-belt transmission pulls the cam follower under the action of force, compresses the spring, and keeps the moving brake plate away from the fixed brake plate, thereby releasing the wire rope.

According to the latest national elevator manufacturing standards, elevators must have upward and downward overspeed protectors (rope clamps).

It depends on how you want to tune in and to what extent. To adjust the tension in general, it is to screw (loosen) the wire rope bolts on the top of the car to make the tension of the wire rope uniform; It can also be used to loosen the wire rope and reinstall it like cutting the wire rope. The latter process is cumbersome, but the effect is obvious.

Drive the elevator to the middle floor, go to the top of the car, and use a tension device to measure the tension of the wire rope. Adjust the tension of the wire rope bolt in the machine room, and if it is not enough, the wire rope should be retracted. After normal operation for a period of time, then adjust it twice according to the above steps, and you can do it.

Dear users, the emergency rescue method after the action of the elevator rope clamp should be to immediately press the emergency call button in the elevator to notify the elevator operation and maintenance personnel for rescue. At the same time, you can also contact the outside world through the intercom system in the elevator to inform you of the floor and elevator number, so that rescuers can find you faster. While waiting for rescue, you should stay calm and do not press the elevator button randomly to avoid aggravating the malfunction.

If there are more than one person in the elevator, the position should be coordinated to allow air circulation to avoid hypoxia caused by too many people. In addition to the above emergency rescue methods, you can also do a good job in the learning and understanding of elevator safety knowledge at ordinary times to avoid accidents in the elevator. For example, don't overload the electric slam ladder, don't press the elevator button indiscriminately, don't run inside the elevator, etc. 
