Transition trolley for supporting heavy-load anchor rod

Abstract

The invention relates to a transition trolley for supporting a heavy-load anchor rod. The transition trolley comprises a frame, a group of driving devices and four groups of limiting devices. A pair of connecting bases are arranged at the front end and the rear end of the frame respectively, each pair of connecting bases are arranged on the outer side faces of a left side plate and a right side plate of the frame in a bilateral symmetry mode, and the four groups of limiting devices are installed on the four connecting bases in a one-to-one correspondence mode. Each limiting device comprises a vertical plate and limiting structures connected with the upper part and the lower part of the vertical plate. Each limiting structure at least comprises a sliding type and a rolling type, holes are formed in the middles of the left side plate and the right side plate of the frame, connecting flanges are arranged on the peripheries of the holes, the driving devices are installed on the connecting flanges, the connecting structures of the limiting devices of different types and the frame are the same, and the connecting structures of the driving devices of different types and the frame are the same. Different combinations can be formed by conveniently replacing different types of limiting devices and driving devices, the problem of relative movement of different telescopic arms and rails is solved, the transition trolley adapts to different roadway working conditions, the bearing capacity is high, and the movement precision is high.

Description

technical field [0001] The invention relates to a trolley, which can drive a cantilever main beam to reciprocate back and forth, and use the cantilever main beam to automatically transport the drilling rig platform to the working face head-on to complete the bolt support operation, belonging to the technical field of coal mine roadway support equipment. Background technique [0002] The feed of the traditional roadway support mechanism generally adopts a box-type telescopic arm structure. The telescopic power of the telescopic arm comes from an oil cylinder or chain drive, and the support mechanism is mounted on the telescopic arm. Using the trolley as the intermediate transition can realize the double-speed linear reciprocating motion of the telescopic arm above the trolley relative to the track below the trolley. Coal mine roadways have different sizes and different working conditions, and it is often necessary to replace transition cars with different structures. However,...

Problems solved by technology

Coal mine roadways have different sizes and different working conditions, and it is often necessary to replace transition cars with different structures. However, due to poor or no interchangeability between transition cars with different structures, the telescopic arm and track even need to be replaced with the transition car.
