Drilling buffering adjustable support for mining

Abstract

The invention discloses a drilling buffering adjustable support for mining. The support comprises legs, leg connecting rods, an upper fixed plate and a drill bit, the middle of the bottom of each legis hollow, the periphery of the bottom of each leg is provided with a corner support, the middle of each installing plate is provided with a spring in a locking way via a fixing screw, a traversing track is fixedly mounted on a drilling platform, support bars are fixedly mounted in the upper of traversing screws via fastening screws respectively, and the support bars are installed in a motor soleplate by welding. Each corner support is of a structure which is larger in the upper and smaller in the lower, the stability is improved, the hardness reaches HRC=55-65 after quenching, the support isantiskid and wear resistance, the middle of the bottom of each leg is provided with a chassis installing hole, a level meter is fixedly mounted in the outer ring of the chassis installing hole, and the levelness is observed visually and adjusted timely; and due to design of the springs and related structure, buffering during work of the motor soleplate and drilling bit is improved, a positioning offset due to a lot of vibration during processing is avoided, and further precision deviation is avoided.

Description

technical field [0001] The invention relates to the field of mining, in particular to a drilling buffer adjustable support for mining. Background technique [0002] Mining machinery is the mechanical equipment used for direct mining of useful minerals and mining preparations. It mainly includes mining machinery for mining metal ore and non-metallic ore; coal mining machinery for mining coal; oil drilling machinery for oil mining. Drilling machines are divided into rock drills and drilling rigs, and drilling rigs are divided into surface drilling rigs and downhole drilling rigs. A rock drill is a machine used to drill holes with a diameter of 20-100 mm and a depth of less than 20 meters in rocks above medium hardness. According to its power, it can be divided into pneumatic, internal combustion, hydraulic and electric rock drills. Dynamic rock drills are the most widely used; surface drilling rigs are divided into steel rope percussion drilling rigs, down-the-hole drilling r...

Problems solved by technology

[0003] Notification number: The patent document of CN 108104810 A provides a lifting type mining machine support, but in actual use, the advantage of the lifting type mining machine support provided by the above document is that by setting the universal direction at the bottom of the mining machine support Wheels are used to facilitate the displacement of the entire rack, that is, to facilitate the movement of the mining machine. At the same time, there is a retractable fixed bracket on one side of the bracket. The fixed feet at the bottom of the fixed bracket can stably fix the rack on the ground to prevent the equipment from The equipment shifts or collapses during operation. The problem is that the fixing method of the bracket is not firm, which poses a safety hazard. In addition, it is not convenient to adjust the position. In addition, there is no buffer for the drilling machine, and it is easy to shift during the drilling process. Therefore, the invention It is necessary to have an adjustable support for drilling buffer in mining
