Description

TECHNICAL FIELD

[0001] The utility model relates to coal mining equipment technical field, concretely is a kind of auxiliary support device for power part of transfer machine. BACKGROUND

[0002] The scraper transfer machine for crossheading is mainly used for coal conveying in the crossheading of underground mine. In the process of coal mining, the coal produced in the coal mining face needs to be transported out in time to ensure the continuous production operation. This transfer machine moves the coal from the coal mining face to the conveyor by the movement of scraper chain, and then the coal is transported to the ground by the conveyor. It can flexibly run in the narrow crossheading and adapt to complex working conditions. The transfer machine includes a machine head, a machine tail, a middle chute and a scraper chain, etc. Under the driving of motor, the scraper chain moves along the chute in a cycle to scrape the coal from the coal mining face into the chute and then transport it to the designated place. The scraper transfer machine usually bears large load and impact force during operation, so the fixing strength of the power part is required to be higher.

[0003] In the prior art, the machine head of the transfer machine is in a raised state as the material needs to be transferred. However, the power part, as the core of the whole transfer machine, is in the raised position of the machine head. The power part is heavy but only connected with the machine head by bolts, which causes the equipment to shake, shift or even overturn during operation. Under the long-term vibration, the connecting parts of the equipment, such as bolts and brackets, are prone to loosen. Once these connecting parts loosen, a series of chain reactions will be triggered, causing the transmission system to fail and affecting the normal operation of the whole scraper transfer machine. Moreover, since the power part is only connected with the machine head by bolts in a suspended state, the power part lacks sufficient support stability. When the equipment is subjected to unexpected external impact, such as rockfall impact of the roadway roof, it is easy to shift or even overturn, which seriously threatens the safety of surrounding equipment and operating personnel.
