) The positioning of the buried scraper conveyor first determines the position of the head and tail, and then determines the center line of the scraper conveyor.
) Lay the intermediate trough according to the determined center line of the conveyor. If a non-metal trough box is used, the middle trough is paved with bricks and cement prefabricated panels, and then bonded with cast stone lining boards. When laying the cast stone lining board, attention should be paid to the straightness, the joints should be as few as possible, and the longitudinal gaps should be staggered to prevent the gaps from being ground into grooves during work. The surface of the conveyor needs to be laid straight. If there is an excessive bend in the plane of the conveyor, it will inevitably lead to uneven stress on the two chains, accelerate the wear between the chain and the cast stone of the trough wall, and even cause the chain to get stuck. The overlap of each tank section should be smooth and without steps. Due to the structural limitations of the tank itself, the deflection of adjacent intermediate slots in the vertical direction should not be too large. If the conveyor is not laid straight, transportation power consumption will increase. Coal accumulation or debris on the machine path should be cleared away.
) When installing the nose and tail, a certain amount of space should be left in the nose and tail to facilitate maintenance and inspection. The center line of the sprocket should be perpendicular to the center line of the conveyor and ensure it is level.
) Installation of scraper chain Before installation, the scraper chain should be pre-connected and the scraper should be evenly distributed in the chain. If there are two chains, choose the same length or assemble them according to the matching chain from the factory. The chain must not be twisted. The welded edge of the ring chain faces upward to prevent the chain and sprocket from getting stuck.
) Inspection and dry operation After the buried scraper conveyor is installed, a comprehensive inspection should be carried out and the conveyor should be started. When the idling operation is small, mainly check whether the driving device and scraper are operating normally. At the same time, make the adjacent middle grooves close together, tighten the chain again, and adjust the length of the chain. During the first two weeks of operation of the scraper conveyor, special attention should be paid to the tightness of the chain. The method of inspection is that if there is a driving device at the tail of the machine, move the driving device. When the upper chain of the tail sprocket has more than two completely loose links, it is necessary to tighten the chain or remove the chain to reduce the chain link. Ring length. If there is only a machine head drive device, the motor needs to be rotated in reverse and when the upper chain at the machine head sprocket has more than two completely loose links. It is also necessary to tighten the chain or remove the chain and reduce the ring.
