What maintenance faults do laser leveling machines need to pay attention to?

In the maintenance of the laser leveling machine, the phenomenon of indiscriminate use of bolts is still more prominent, because the performance and quality of bolts do not meet the technical requirements, resulting in frequent mechanical failures after maintenance. But in the actual maintenance, but most of the ordinary nuts are used, it is very difficult to disassemble for a long time, some technical requirements stipulate that new bolts must be replaced after disassembling and assembling several times, because the maintenance personnel do not understand these situations, and repeatedly reuse unqualified bolts, it is easy to lead to the failure or accident of Sanren mechanical laser leveling machine. Therefore, when repairing the laser leveling machine, when the bolt is damaged or lost, the bolt that meets the requirements should be replaced in time, and the bolt should not be used indiscriminately.

Most of the fixing or connecting bolts of each part of the laser leveling machine have tightening torque requirements, such as injector fixing bolts, cylinder head bolts, connecting rod bolts, flywheel bolts, etc., some stipulate the tightening torque, some stipulate the tightening angle, and also specify the tightening sequence.

First, the laser leveling machine should stand flat, first observe the ground that needs to be leveled, visually detect the high point and location of the ground, and then find a reference point at the high end of the ground, and level it from the high place to the low place in turn. Excavate the soil above the reference point and fill in the low-lying lot, which is generally leveled visually. The first thing to level is to level the station and stand firmly, and first level the position under the track between leveling.

Let the laser leveler track stand on a flat and solid ground, so as to ensure that the driver will not make mistakes during visual inspection, and the leveling work is half the success. Second, choose a good reference object reference object commonly known as elevation, for novices who do not grasp much, you can increase the density of the elevation point, such as five meters one, or even three meters one. For the situation that the original ground is generally higher than the actual elevation, it is necessary to increase the elevation uniformly, such as 30 cm and 50 cm.

For skilled old drivers, you can choose the ground that has been leveled or the ground of different colors as a reference, and the choice of reference directly affects the overall flatness of the ground. 3. Don't be greedy and greedy, after determining the reference, the rest is that the laser leveler digs slowly, don't dig too much each time you don't grasp it, and rather dig a few more times than dig too much. For large-scale leveling, don't dig too wide every time, generally the width of two cars is about the same, and the error will become larger when digging wide.

Fourth, believe in the laser leveling machine, don't believe too much in the eyes of the ground for a long time, it is easy to deviate. If possible, use the level as much as possible for reference. In addition, if the laser leveler stands flat, the bucket is close to the ground and does not understand, and the rotation of 180 degrees can see the difference in the nearby highlands.

After the fine leveling is completed, the leveling of individual high points or low points is completed according to the specific situation, and the entire site is leveled later.

1. When using Shandong Huaang Machinery laser leveling machine, try to avoid collision and friction with concrete walls, steel structure supports and other objects. to avoid damaging the protective layer on its surface.

When cleaning and wiping the laser leveler, choose a clean and soft rag to avoid scratching the paint layer on the surface.

2. Do not use a strong alkali or strong acid cleaning agent to clean the membrane on the leveler, so as not to cause discoloration or deformation of the membrane. Do not use some cleaning agents containing organic solvents, such as washing powder, strong alkali, etc., to scrub the paint on the cab, and at the same time maintain the electroplating layer of the laser leveling machine, so as not to cause corrosion hazards and shorten the service life of the laser leveler.

Three: Although the laser screed machine is coated with membrane material, which has good elasticity and flexibility, it should also avoid scratches on the carport by spikes in the case of extrusion force in daily use. Do not violently bump, scratch and scratch the paint surface of the laser leveler, and try not to collide with other solid objects on the way.

Common fault causes and ways to discharge faults of Sanren mechanical laser leveling machine:

1.The common material deviates in the leveling process because the material is not square when feeding, and the pressure on both sides of the leveler is uneven, resulting in a deviation to the pressure when the material is conveyed.

2.When the roller slips when feeding, the target material cannot be driven because the pressure of the feed roller is not enough to hold down the material, and the pressure of the pressing spring on the feed roller is adjusted clockwise.

3.If the feeding soil stops or is too late, and the time relay delay adjustment in the electric control box is incorrect, the solution is to adjust the appropriate delay of the time relay according to the feeding speed of the feeder in front.

Laser screed machine is an indispensable machine and equipment in ground construction projects, it is not only fast, high work efficiency, but also high precision, small error, save your investment costs, can bring great profits, but there are many people do not know how to debug Sanren mechanical laser screed machine before work, let's talk about it below.

1. When starting the punch of continuous stamping, the screw must rotate clockwise to adjust the speed of the feeder, and the slider moves slightly slowly, so that you can see whether the slider touches the nylon washer and the length adjustment screw in the reciprocating motion.

2. Before connecting the power supply test, check whether the feeding direction is correct.

3. If the speed of the punch is constant, and the feed distance needs to be shortened from long to short, the lead screw should be guided first to reduce the falling distance of the floating rod, and then rotate the screw clockwise to adjust the speed so that the feed can match the speed.

4. Adjust the distance between the material rack and the laser leveler and the feeder, and adjust the distance appropriately according to the speed of the punch and the length of the feeder. After leveling, the material should be able to enter the feeder and mold smoothly.

About the operation process of Sanren Machinery laser leveling machine:

During operation, the concrete leveler should start first before it can start, and the internal combustion engine should first go to medium speed, and then modulate to high speed.

It is strictly forbidden for the new concrete screed to vibrate on solid ground.

When rolling the soft roadbed, it should be rolled 1 2 times without vibration, and then vibrated and rolled.

When rolling, the vibration frequency should be consistent, for the new concrete leveler that can adjust your vibration, the vibration frequency should be adjusted before operation, and the vibration frequency should not be adjusted without earthquake.

1. Preparation.

After the base layer is processed, the equipment of the laser leveling machine is debugged, and the fixed reference level point is made according to the original leveling point; Laying plastic film, tying steel mesh (according to design needs), supporting side molds; A laser emitter is erected to introduce the floor elevation into the laser leveler according to the original leveling point.

2. Conveying concrete.

Commercial concrete is used and transported to the construction site by concrete truck.

3. Standard high school nucleus.

Use the handheld receiver to check the floor elevation, introduce the elevation into the laser leveler, and adjust the datum point on the leveling machine ( .

2. Concrete paving.

Within the effective construction scope of the leveling head of the laser leveling machine, the concrete is initially leveled to 1-2 higher than the floor elevation (the specific height depends on the concrete slump), and then the vibration, compaction and leveling work are completed by the Swiss concrete laser leveling machine at one time.

3. Wipe and receive.

When the concrete after pouring reaches the initial setting, it is polished by a grinding machine, and then wiped and collected by hand.

4. Maintenance. After the concrete is finished, it is not allowed to move heavy objects on the floor for at least 7 days, and should maintain a moist curing state, spray curing agent curing (according to the design needs), in order to achieve a good curing effect, the surface should be covered, so that the concrete is isolated from the outside, during the curing period, when the strength of the surface layer of concrete does not meet the requirements, it is strictly forbidden to go to the master.

5. Cutting seams. The cutting joints should be carried out after the completion of the floor surface treatment according to the design requirements, that is, to ensure that the concrete is carried out before the final setting, and the spacing, width and depth of the cutting joints should meet the requirements of the design and construction specifications.

6. Miscellaneous. Caulking, protecting, until the concrete reaches strength.

During concrete construction, it is generally leveled by hand, and the emergence of Sanren mechanical laser leveling machine completely liberates the inconvenience of manual operation. It greatly reduces the labor cost for the construction site, and has a significant improvement in the leveling effect of concrete.

Laser leveling machine: In the case of accurate elevation setting of professional and technical personnel, there are mechanical operators to accurately level the concrete surface under the control of the laser leveler, and the leveling machine will automatically calibrate and control the leveling machine at a high frequency to ensure the accuracy of the leveling plane. Concrete laser leveling is a scientific and reasonable design, and the operation of the equipment does not need to be assisted manually, which is the convenience, scientificity, technology and so on in the design process.
