Abstract

The invention discloses a chain arm saw type top cutting pressure relief device. The chain arm saw type top cutting pressure relief device comprises a chassis system, a sliding guide rail system, a sliding platform system and a chain cutter system; the chain cutter system is mounted on the sliding platform system; the sliding platform system is mounted on the chassis system; and the chassis system is used for driving the sliding platform system to move. When the chain arm saw type top cutting pressure relief device is used, the whole equipment is moved to the operation position through the chassis system, then supporting legs at the two ends of the sliding guide rail system stretch out, then the chain cutter system is started, and cutting operation can be achieved; and along with control of a drive assembly, stepping operation of the chain cutter system can be achieved, invalid actions of cutter retreating are reduced, cutter clamping faults are effectively reduced, and the work efficiency is improved. Through cooperation of guide rails and wheels, the linearity of cut seams of the chain cutter system is better; and in addition, wheel assemblies are rotationally connected with a platform through connecting shafts, all the wheel assemblies can make contact with the guide rails, and therefore stability during cutting feeding is guaranteed, and the cutting quality is improved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a chain arm saw type roof cutting pressure relief device. Background technique [0002] Existing roof cutting and pressure relief equipment are mainly divided into drilling and blasting equipment and crawler chain arm saw cutting equipment. Among them, the drilling and blasting equipment has the problems of cumbersome work and heavy workload, and there are relatively large safety hazards and poor seam quality. The crawler-type chain saw cutting equipment has disadvantages such as poor seam quality, poor continuity, poor adaptability, and invalid action of the emptying knife. Contents of the invention [0003] The purpose of the present invention is to provide a chain arm saw type roof cutting pressure relief device, which can effectively solve the problems of poor seam quality and poor safety. [0004] In order to solve the problems of the technologies described...
