The invention provides a supporting device for a coal mine drilling machine. The device comprises a base, an idler wheel set installed on the base and supporting pieces installed at the four corners of the base respectively, wherein the idler wheel set comprises a connecting rod, an installation rod and two idler wheels, the top end of the connecting rod is connected with the base, and the installation rod is installed at the bottom end of the connecting rod in a sliding mode; the two idler wheels are respectively arranged at the two ends of the installation rod; the connecting rod is sleevedwith a first spring, one end of the first spring is connected with the base, and the other end of the first spring abuts against the installation rod; each supporting piece comprises an oil cylinder,a supporting block, a locking nut and a second spring; each oil cylinder comprises a cylinder body and a telescopic rod telescopically connected with the cylinder body, and the ends, away from the cylinder bodies, of the telescopic rods are connected with the supporting blocks; the locking nuts are in threaded connection with the telescopic rods; the telescopic rods are sleeved with the second springs, one ends of the second springs are connected with the supporting blocks, and the other ends of the second springs abut against the locking nuts. The supporting device for the coal mine drillingmachine has the advantages of being good in stability, resistant to impact and not prone to damage.
Description
technical field [0001] The invention relates to the field of coal mine drilling rig equipment, in particular to a support device for a coal mine drilling rig. Background technique [0002] my country's economic construction has achieved rapid development in recent years. Economic development is inseparable from the exploitation and utilization of natural energy. my country's coal mine resources are particularly rich, so the rational exploitation and utilization of coal mine resources plays a vital role in my country's economic development. Coal mining methods include underground mining and open-pit mining, and coal mining rigs are the most commonly used coal mining machinery in these two mining methods. [0003] At present, the coal mine drilling rig needs to use a supporting device to assist it to move and support it during use, but the existing supporting device still has certain deficiencies. It is easy to cause damage to the drilling rig due to bumps during the movement ...
