Support dismounting vehicle

Abstract

The invention relates to the technical field of roadway support and discloses a support dismounting vehicle. The vehicle comprises a second vehicle body, a second support, second sliding ways, second nut sliding blocks, second lead screws, second driving devices and a mounting arm, wherein the second support is connected with the second vehicle body in a lifting manner; the second sliding ways are connected with the second support and extend in the length direction of the second vehicle body, the number of the second sliding ways is two, and the two second sliding ways are arranged in the width direction of the second vehicle body at intervals; the second nut sliding blocks are arranged in the second sliding ways, and at least part of the second nut sliding blocks are located on the outer side of the second sliding ways; the second lead screws are arranged in the second sliding ways and are in threaded fit with the second nut sliding blocks; the second driving devices are arranged at one ends of the second sliding ways and are connected with the second lead screws; and the mounting arm is used for dismounting a supporting shed frame from the roadway. The supporting shed frame can be automatically disassembled, so automation and unmanned operation during working face tunneling are realized, and construction efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of roadway support, in particular to a support dismantling vehicle. Background technique [0002] Existing mechanized excavation of rectangular roadways generally adopts the excavation method of supporting while digging, and the working face of the roadway requires a large number of workers to work together at the same time, and these workers are in extremely harsh working environments. According to statistics from the National Health Commission, by the end of 2018, the cumulative number of reported occupational cases in the country exceeded 970,000, ranking first in the world, most of which were concentrated among mine workers. In mines, especially the mine excavation working face, the environment is harsh. Dust, heat damage, noise and toxic and harmful gases constitute the "four evils", which seriously threaten the health of workers and lead to the occurrence of various occupational diseases, such as pneum...

Problems solved by technology

[0003] In addition, during the excavation construction process of the existing rectangular roadway, the support work of the roadway is the most important factor restricting its automation and unmanned operation.

At present, it is difficult to automate the anchoring work of the ordinary bolt support method. Although some manufacturers' equipment is being tested, the failure rate is high, and it has not yet been widely used.
