The installation of the scraper conveyor requires the following work:
1. Positioning:
First, determine the position of the head and tail of the machine, and then determine the centerline of the scraper conveyor.
2. Laying intermediate grooves:
Lay the middle groove according to the determined conveyor centerline. If non-metallic trough boxes are used, the middle trough shall be paved with bricks and cement prefabricated panels, and then bonded with cast stone lining panels. When laying the cast stone lining board, attention should be paid to straightness, with as few joints as possible, and longitudinal gaps should be staggered to prevent the joints from being ground into grooves during work. The surface of the conveyor needs to be laid flat. If there is too much bending in the conveyor plane, it will inevitably lead to uneven force on the two chains, accelerate the wear between the chains and the cast stones on the groove wall, and even cause chain jamming. The overlap of each section of the groove should be flat without steps. Due to the structural limitations of the groove itself, adjacent intermediate grooves should not deviate too much in the vertical direction. If the conveyor is laid unevenly, the transportation power consumption will increase. The accumulated coal or debris on the machine track should be cleaned up.
3. Install the front and rear of the machine:
There should be some space left at the front and rear of the machine for easy maintenance and repair. The centerline of the sprocket should be perpendicular to the centerline of the conveyor and kept horizontal.
4-pack scraper chain:
The scraper chain should be pre connected before installation, and the scraper should be evenly distributed in the chain. If there are two chains, they should be of equal length or assembled according to the paired chains from the factory. The chain must not have any twisting phenomenon. The welding edge of the circular chain is facing upwards to prevent the chain and sprocket from getting stuck.
5 Inspection and Airfreight:
After the installation of the scraper conveyor, a comprehensive inspection should be conducted and the conveyor should be started. Idle for 2 hours, mainly check whether the driving device and scraper are operating normally. At the same time, make each adjacent middle groove close together, tighten the chain again, and adjust the chain length. During the two weeks of operation of the scraper conveyor, special attention should be paid to the tightness of the chain. The method of inspection is: if there is a driving device at the tail of the machine, jog the driving device. When there are two or more completely loose chain links on the upper chain of the tail sprocket, tighten the chain or remove the chain to reduce the length of the chain links. If there is only the head drive device, it is necessary to reverse the motor and jog it, when there are two or more completely loose chain links on the upper strand chain at the head sprocket. Similarly, it is necessary to tighten or dismantle the chain to reduce the loop.
