A crawler type thin coal seam bolter

Abstract

The invention relates to mine exploration equipment and provides a crawler-type thin seam anchor rod drill rig. The crawler-type thin seam anchor rod drill rig comprises a workbench and a crawler-typetravelling mechanism base disc, wherein the base disc is connected with the workbench by an arranged lifting mechanism, the base disc enters a middle part of one side of a thin seam and is sunken toform a counter groove, a fixed lug seat is arranged in the counter groove and is used for being hinged with the lifting mechanism, one end of the lifting mechanism is hinged with the fixed lug seat, the other end of the lifting mechanism is hinged with the workbench and is pushed by a hydraulic mechanism in the lifting mechanism so as to ascend and descend in a rotation way, the lifting mechanismis sunk into the counter groove when descending to the lowest part so that the height of the drill rig is 1.1-1.5 meters. By the crawler-type thin seam anchor rod drill rig, the problems of mine resource exploration of the thin seam and application of mine resource in coal mine transportation of a vertical shaft are solved, and the mine resource exploration efficiency and safety of the thin seam is improved.

Description

technical field [0001] The present application relates to the field of coal mine construction equipment, in particular to a crawler-type thin coal seam bolter drilling vehicle. Background technique [0002] Before 2006, my country's bolter rigs all relied on imports. The quality and size of their components were relatively large, and they were mainly used in adit mines with good mine conditions. In 2006, Shanxi Tiandi Coal Machinery Equipment Co., Ltd. successfully developed my country's first rock bolter, and it was popularized and applied in shallow coal seams with good roof and floor conditions such as Shendong and Shaanxi Coal, and achieved good results. However, the current use of rock bolters is mainly suitable for medium-thick coal seams, and cannot be applied to thin coal seams with a mining height range of 2 meters or less. [0003] my country's thin coal seam coal resources are abundant, accounting for more than 20% of the country's coal reserves. Among the proven...

AI Technical Summary

Problems solved by technology

Mining of thin coal seams in my country is mainly carried out by blast mining and coal plows. The production efficiency of blast mining is low and the safety is poor. Rod drilling rigs can be widely used in thin coal seam roadway support, with high mining efficiency and good safety, so the research and development of thin coal seam bolter rigs is of great significance to the mining of thin coal seam resources

[0004] At the same time, most of the coal resources in our country are buried deep underground, and the size of the mine roadway is small, and most of them are transported by vertical shafts. However, the existing rock bolter parts are large in size and cannot be broken down into the size suitable for domestic vertical shaft transportation cages. It is difficult to transport and can only be transported in Used in inclined shafts with shallow coal seams
