Abstract

The invention discloses a combined-type clamping device used for a clamping drill rod of an underground drill rig. The device comprises an insertion sleeve, an outer baffle, an inner baffle, a clamping tile, an inner slope drive block and an outer slope drive sleeve, wherein the outer baffle and the inner baffle are firmly installed in sequence on the outer side of the left end of the insertion sleeve; a protective shell is disposed on the outer side of the inner baffle; the clamping tile is installed in the middle of the insertion sleeve in a sliding manner; the upper end of the clamping tile is firmly connected to the lower end of the inner slope drive block; the outer slope drive sleeve is disposed on the outer side of the inner slope drive block in a sliding manner; a bearing used to reduce relative friction force is disposed between the outer slope drive sleeve and the inner baffle; the right end of the insertion sleeve is firmly equipped with an end face cover plate by a drive threaded sleeve; and a compressing spring is disposed between the end face cover plate and the outer slope drive sleeve. The device disclosed by the invention is characterized by rational design, a simple structure, convenient use, a small volume, a light weight, convenient assembly and disassembly and good clamping effects.

Description

technical field [0001] The invention belongs to the technical field of coal mine machinery, and relates to a clamping device, in particular to a combined clamping device for drilling rods of a tunnel drilling rig. Background technique [0002] At present, my country's coal mining speed is growing rapidly. With the gradual increase of coal mining depth, the risk of coal mine gas outburst and explosion is also increasing, and coal mine gas outburst and explosion accidents often occur. Putting it into the atmosphere will not only damage the atmospheric environment, but also does not meet the requirements of energy saving and emission reduction. Therefore, the method of drainage and comprehensive utilization of mine gas has been adopted at home and abroad to solve this problem. However, mines put forward higher requirements and a wider range of use for drilling rigs, which are indispensable in the safety measures for preventing gas accidents. Long-distance drilling under high-ga...
