A device and method for quickly dismantling, separating and assembling the middle transfer point of a scraper

Abstract

The invention provides a device and method for rapidly disassembling and assembling a middle joint point of a carry-scraper. The device comprises a hydraulic jack, a sleeper box and moving pin rollers. A separation layer iron plate used for holding the hydraulic jack is arranged in the middle of the sleeper box. Moving pin roller fixing holes are formed in the side faces, where the separation layer iron plate is located, of the sleeper box. A hydraulic jack oil pipe connector hole is formed in the side face of the portion, above the separation layer iron plate, of the sleeper box. The side face of the hydraulic jack is provided with a hydraulic jack oil pipe connector installed in the hydraulic jack oil pipe connector hole. The two sides of each moving pin roller are respectively provided with a moving pin roller fixing end installed in the corresponding moving pin roller fixing hole. The height of the jack is adjusted by 0 cm to 10 cm through hydraulic pressure, a left turning oil cylinder and a right turning oil cylinder of the device extend and retract at the same time according to the hydraulic principle, so that the middle joint point of the carry-scraper is rapidly disassembled and assembled, the labor intensity is relieved, and the reliability and stability of disassembling of the middle joint point are improved.

Description

technical field [0001] The invention relates to the field of trackless equipment, in particular to a device and method for quickly disassembling, separating and assembling the intermediate junction point of a scraper. Background technique [0002] At present, the scrapers of mining enterprises all adopt the hinged structure of the front and rear racks. With the increase of the service life of the equipment, there are more and more wear and tear failures of the middle hinge point. Every time the middle junction point is removed and separated, 6 sleepers and 6 jacks are required. Stable, 4 hand chain hoists pull in opposite directions to separate the front and rear racks, and 6 sleepers and 6 jacks are also required to be stable during assembly, and can only be assembled by pulling in opposite directions. Maintenance is time-consuming and laborious, and it is easy to cause secondary damage to equipment and personal injury. Contents of the invention [0003] In view of the de...

[0002] At present, the scrapers of mining enterprises all adopt the hinged structure of the front and rear frames. With the increase of the service life of the equipment, there are more and more wear and tear failures of the middle hinge point. Every time the middle handover point is removed and separated, 6 sleepers and 6 jacks are required. Stable, 4 hand chain hoists pull in opposite directions to separate the front and rear racks, 6 sleepers and 6 jacks are also required for stability during assembly, and can only be assembled by pulling in opposite directions in the same direction. Maintenance is time-consuming and laborious, and it is easy to cause secondary damage to equipment and personal injury
