Steps of installation of scraper chain conveyor

The assembly of the mc-type buried Scraper Conveyor is generally the first to assemble the parts in the manufacturing plant, and then the separate parts are transported to the application site to stop the assembly of the whole machine. The assembly procedure is roughly the following:

1. According to the assembly drawing of the mc type buried scraper conveyor, set the longitudinal middle line of the equipment. The longitudinal middle line is the assembly reference for all conveyors. Outside the shop floor, it is usually marked with the coordinates of the factory grid. When marking, it is best to use the factory column net as a benchmark to draw out the longitudinal middle line of the conveyor and the horizontal middle line of the head and tail wheel. If the equipment associated with the conveyor has been assembled in place, during the assembly, the intermediate line should be determined based on the size of the connection of these adjacent equipment. The size of the system and the column network of the plant are for reference only. Better to ensure that the delivery system is reliable.

2. On the longitudinal middle line of the conveyor, firstly walk out of the middle position of the axis of the head axle, and then measure along the longitudinal middle line segment by segment. The final position of the tail shaft is determined by the overall length of the conveyor.

3. Using the above middle line as a reference, affirm the position of the foot of the irrelevant chassis, the position of the rail assembly, and the intermediate size of the drive assembly.

4. After affirming the intermediate status, joint construction drawings of civil construction shall be used to find out the unrelated layout components and be cleared, and then all kinds of rack assembly shall be stopped according to the requirements of the assembly drawings.

5. After the assembly of the frame (including the head frame, tail frame, intermediate bracket and drive assembly frame, etc.), stop the rail assembly.

6. Assemble the sprocket assembly, tighten the sprocket assembly, and sprocket assembly to ensure that the coplanar misalignment is as small as possible; the sprocket shafts should be parallel to each other; the sprocket that is uniformly linked to the chain should be kept in a uniform plane to prevent skew and runout. The coplanar deviation of the sprocket will cause the chain to swing laterally, which will cause the chain and the sprocket to produce sideways wear, strike, and weaken the coupling at the interference fit of the chain. In severe cases, the whole machine such as the split pin can be sheared off, and Produce the waist of the chain plate to climb the top of the tooth.

7, assembly drive assembly.

8, assembly conveyor chain. Initially, each segment is divided into several groups according to the length accuracy, flattened and straightened on the ground; afterwards, reasonable matching and connection are stopped, so that the lengths of the multi-hanging conveyor chains on the unified conveyor are as equal as possible, and the layout of the accessories of the conveyor chain is asymmetrical. When there are several parallel applications of the chain, special attention should be paid to the correct configuration of the left and right sides. In addition, before the chain is fitted with the sprocket, it is necessary to stop the inspection of the disk to check whether the engagement is too tight or too loose. If it is too tight or does not mesh, the chain cannot be assembled.

When assembling the chain, it is also necessary to pay attention to the assembly bias of some anti-locking machines and the operation bias of the chain to prevent it from hitting, jumping, or falling off during a collision. When assembling the chain on site, the tensioning assembly should be loosened to the limit position, and after the chain is connected in series, the chain can be further tightened. If a secondary attachment is set on the conveyor chain, it should also be assembled at this time.

9. Assemble the load bearing member on the conveyor chain attachment. In order to ensure the assembly accuracy, generally the first load bearing members should be grouped into 4 or 8 groups; then the first one of each group should be installed first and then the second one of each group should be installed; Secure and adjust the clearance or stacking interval of adjacent load bearing members. If the load-carrying members are repeated, they should be assembled early.
