Problems solved by technology
[0006] The purpose of the present invention is to provide a roadway rockfall prevention safety support device for coal mine development, to solve the above-mentioned background technology, the existing connection methods are mostly manually fixed or installed one by one driven by electric equipment such as motors and telescopic rods, and there are still some Over time, the crushed soil and slag will fall through the roof of the mesh into the support structure or other structures installed in the roadway below the support structure, which will not only affect the operation and use of other equipment in the roadway, but also easily lead to the failure of the support structure. The problem of increased weight of the device

The invention discloses a rockfall prevention safety support device for a roadway used in coal mines, comprising a support side plate, a partition plate, a connection cavity, a blowing and suction fan and a fixed plate, and a moving wheel is embedded in the bottom of the support side plate , the outer side of the axle is fixed with a first bevel tooth, the top of the supporting side plate is fixedly installed with a supporting top plate, the upper surface of the movable plate is reserved with a feeding hole, and the two sides of the sleeve plate are fixed There is a fixed cylinder, a movable cylinder is movably arranged below the sleeve plate, and a sleeve block is fixed on the outer side of the movable cylinder. The coal mine adopts the roadway anti-falling rock safety support device, which can adjust the overall width of the roadway support by manual operation, and can realize the stable connection of the whole support with the roadway side wall and the ground part, which greatly saves the installation cost and At the same time, the dregs dropped from the top wall of the roadway can be collected and discharged, which effectively reduces the cleaning work burden of the roadway support in the subsequent use process.
Description
technical field [0001] The invention relates to the technical field of coal mining, in particular to a roadway anti-falling rock safety support device for coal mining. Background technique [0002] In coal mining, the roadway needs to be excavated. In order to ensure the stability of the roadway, it is usually necessary to use a support device to support the inner wall of the roadway. Usually, the cross-section of the roadway is mostly arched. The structural requirements of the protective device are relatively high. For example, a roadway supporting device with a shock absorption function disclosed in the publication number CN209942854U includes a first rectangular plate, and the first rectangular plate is provided with two groups, and the two groups of The first rectangular plate is symmetrically arranged, the lower surface of the first rectangular plate is fixedly welded with a conical block, and the upper surface of the first rectangular plate is provided with a first spr...
