The Problem Of Pushing And Moving suspension hydraulic prop
The fully mechanized mining face of hydraulic acrow props should be kept straight, which is directly related to whether the top floor of the coal shearer is straight or not, and also related to whether the pushing and sliding and moving supports are straight. The two influence each other. If hydraulic props If the roof and floor are cut excessively and unevenly, or even cut out the steps, the frame cannot be pushed and moved smoothly, and the frame cannot even be pushed or moved, which affects the timely support of the frame and the top plate, and the top coal may fall accident;
The distance of pushing and sliding the acrow prop and moving the frame is not enough, which in turn affects the cutting depth of the coal face; the roof and floor are undulating, and the conveyor and support are skewed. The shearer drum may cut the coal slab or the top beam. Whether the pushing and staying and moving frame are straight is the key to keeping the working face flat and straight.
Problems related to acrow prop protection
The protective devices of hydraulic acrow props in fully mechanized mining face should be selected and used correctly according to the underground conditions. Improper use may cause malfunctions.
For example: If the movable side guard plate malfunctions, it may cause gangue and bumps and damage to the hydraulic acrow props. To prevent the above-mentioned accidents of acrow prop, it is necessary to operate and use various protective equipment correctly in strict accordance with the requirements of operating procedures and regulations to prevent misoperation and make it play an effective protective role.
