Embodiment Construction

[0011] Referring to the accompanying drawings, a stabilizing device for a coal mine drilling rig includes a hydraulic cylinder 5, the hydraulic cylinder 5 is connected to the hydraulic system of the drilling rig through an oil pipe 6, and the piston rod 4 of the hydraulic cylinder 5 is integrated with the extended lower connection part 3. The upper end of the extended lower connecting part 3 is threadedly connected with the lower end of the extended upper connecting part 2, and the extended upper connecting part 2 is integrated with the lower end of the supporting end 1. The supporting end 1 is connected with a round drill pipe, and the lower end of the hydraulic cylinder 5 passes through a pin 8 is connected with support base 7, and the diameter of round drill rod is 73.5mm.

[0012] Since the oil pipe of the device is connected with the hydraulic system of the drilling rig, the hydraulic cylinder can be pressurized and stabilized through the hydraulic system of the drilling r...

Abstract

The invention discloses a stabilizing device for a coalmine driller. The stabilizing device comprises a hydraulic oil cylinder which is connected to a hydraulic system of the driller through an oil pipe. A piston rod of the hydraulic oil cylinder is connected to a lengthened lower connecting portion integrally, the upper end of the lengthened lower connecting portion is fixedly connected to the lower end of the lengthened upper connecting portion, the lengthened upper connecting portion is connected to the lower end of a supporting end head integrally, the supporting end head is connected to a round drill, and the lower end of the hydraulic oil cylinder is connected to the supporting base through a pin roll. According to the device disclosed by the invention, a fixed mechanical operation of the driller in a large-section roadway is realized, so that the labor intensity is lowered, and the reliability and efficiency for fixing the body of the driller are increased.

Description

technical field [0001] The invention relates to the field of drilling rig installation, in particular to a stabilizing device for coal mine drilling rigs. Background technique [0002] Coal mine drilling rigs need to be fixed with fixing devices during construction to ensure that the drilling rig remains stable under the action of powerful drilling rig torque, otherwise, the drilling rig will be misaligned and the drilling will be scrapped. [0003] At present, coal mine drilling rigs are fixed by hydraulic units. The main working principle is to respectively fix four hydraulic units on the four feet of the drilling rig, manually pressurize the four units, and fix the body of the drilling rig. This method of manual pressurization is labor-intensive, low in efficiency, easy to release pressure, heavy in weight and difficult to move, and cannot meet the requirements of the roadway height. Contents of the invention [0004] The object of the present invention is to provide a...
