Rapid excavation roadway support equipment

Abstract

The invention relates to the technical filed of roadway supports, and discloses rapid excavation roadway support equipment. The rapid excavation roadway support equipment comprises a first supportingplate and a second supporting plate, a first guide rod is slidably connected to the right end of the first supporting plate, the right end of the first guide rod is slidably connected with the left end of the second supporting plate, fixing seats are correspondingly arranged at the left end of the lower surface of the first supporting plate and the right end of the lower surface of the second supporting plate, the fixing seats are fixedly connected with fixing rods, hooks are connected to the two ends of the fixing rods in a clamped mode, connecting rods are connected to the lower ends of thehooks, second sliding plates are connected to the lower ends of the connecting rods, and second guide rods are slidably connected to the lower ends of the second sliding plates. According to the rapidexcavation roadway support equipment, the first supporting plate and the second supporting plate which can slide relatively are arranged, the equipment can be suitable for roadways with different widths, meanwhile the distance between a first sliding plate and the second sliding plates can also be freely adjusted, and thus the equipment can also be suitable for roadways with different heights.

Description

technical field [0001] The invention relates to the technical field of roadway support, in particular to a rapid excavation roadway support equipment. Background technique [0002] In the process of mine excavation, the fully mechanized excavation of the underground roadway is completed by the excavation of the roadheader. At the same time, the support work is accompanied by the excavation process. The two works complement each other. The newly exposed roadway roof is also supported by the excavation and excavation. Support is divided into temporary support and permanent support. When the roadheader cuts and excavates a step, an unsupported newly exposed roof appears in the head of the roadway, and support work is required. After the support is completed, the full-mechanized excavation of the roadheader will be carried out again. [0003] In recent years, with the continuous increase of the installed power of roadheader products, the work efficiency of roadheaders has been ...

AI Technical Summary

Problems solved by technology

[0003] In recent years, with the continuous increase of the installed power of roadheader products, the work efficiency of roadheaders has been continuously improved, and the requirements for the production tasks of fully mechanized excavation work have been continuously improved. However, the above-mentioned supporting support work requires the roadheader to stop, reverse and wait after digging. , this process and the structure of supporting supporting equipment greatly limit the improvement of excavation work efficiency

[0004] Chinese patent (notification number: CN207920616U) discloses a support device for rapid excavation of bottom pumping roadways, which belongs to the technical field of roadway support devices, and can solve the difficulty of supporting hard bottom pumping roadways, which causes the progress of coal seam gas control projects. The problem of slowness, including the anchor net support device and the iron shed support device matched with the anchor net support device, there are several guard plates between the anchor net support device and the top of the iron shed support device, the anchor net support device There are several plate girders between the iron shed support device and the side wall. Among them, the anchor net support device is a rectangular anchor net. There are several anchor rods. There is an anchor rod on the side wall of the anchor net. The iron shed support device includes the ceiling and outriggers. One end of the outriggers is connected to the ceiling. The structure of the device is relatively simple, and the width and height cannot be adjusted freely. The range is narrow, so the device needs to be improved
