Problems solved by technology

[0002] During the mining process of coal mines, supporting devices need to be used to shield the working face of the roadway to avoid damage to construction equipment and personnel caused by ore falling. The existing supporting devices are basically integrated structures. The overall volume is huge, and it is generally difficult to move into a narrow roadway. Especially for super-long working faces, the mine pressure is more intense than that of ordinary working faces, resulting in higher requirements for advanced support of working face roadways. Makes the one-piece device easily affected by the internal environment of the roadway when it is deployed

Abstract

The invention provides a forepoling device for an ultra-long working face roadway. The forepoling device comprises a top protection plate; the upper ends of the first driving parts are detachably connected with the top protection plate, and the lower ends of the first driving parts are detachably connected with the ground of the roadway; the two groups of side protection plates are detachably hinged with the side parts of the top protection plate; and the upper ends of the second driving parts are detachably connected with the top protection plate, and the lower ends of the second driving parts are detachably connected with the side protection plates. Compared with the prior art, the split type supporting device has the advantages that the split type supporting device is achieved through detachable connecting structures among all the components, and the supporting effect is good; according to the supporting device, all the components can be transported in the roadway respectively, so that the whole supporting device can carry out supporting in the small roadway, the universality of the whole supporting device is improved, and the coal mining cost is reduced.

Description

technical field [0001] The present application relates to the technical field of roadway support, in particular to an advance support device for a super-long working face roadway. Background technique [0002] During the mining process of coal mines, supporting devices need to be used to shield the working face of the roadway to avoid damage to construction equipment and personnel caused by ore falling. The existing supporting devices are basically integrated structures. The overall volume is huge, and it is generally difficult to move into a narrow roadway. Especially for super-long working faces, the mine pressure is more intense than that of ordinary working faces, resulting in higher requirements for advanced support of working face roadways. This makes the integrated device easily affected by the internal environment of the roadway when it is deployed. Contents of the invention [0003] This application aims to solve one of the technical problems in the related art a...
