Problems solved by technology
During frozen drilling, in order to improve construction efficiency, four drilling rigs need to be arranged on a well plate with a frozen hole diameter of about 12 meters. The distance between the two drilling rigs is very small, and the space around the drilling rigs is very narrow. , so the movement method adopted by the oil drilling rig cannot be applied here

The invention discloses an integrated drilling machine moving device. The integrated drilling machine moving device is characterized in that a drilling machine base is arranged on a left bearing frame and a right bearing frame, the left bearing frame and the right bearing frame are connected through horizontal supporting rods, oblique-angle supporting rods and pin shafts, the left bearing frame and the right bearing frame are in contact with the ground respectively through a rolling lever assembly, a double-row chain wheel driving assembly and a single-row chain wheel driving assembly, the rolling lever assembly, the double-row chain wheel driving assembly and the single-row chain wheel driving are arranged under the left bearing frame and the right bearing frame, cylindrical worm speed reducers and hydraulic motors are arranged above the left bearing frame and the right bearing frame, single chain wheels are arranged on output shafts of the cylindrical worm speed reducers, the hydraulic motors are connected with the cylindrical worm speed reducers through couplers, the single chain wheels and the double-row chain wheel driving assembly roller chain are in transmission through roller chains, and the double-row chain wheel driving assembly and the single-row chain wheel driving assembly are in transmission through roller chains. The integrated drilling machine moving device can achieve parallel movement, turning and rotation of the whole drilling machine by controlling the output directions and the output rotation speeds of the two lateral hydraulic motors. Thus, the drilling machine can be integrally, safely, quickly and accurately moved, the time for moving the drilling machine in a drilling process is reduced, and the production efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of drilling rigs, and relates to an overall moving device for drilling rigs. Background technique [0002] In coal mine vertical shaft shaft frozen drilling construction, a shaft generally needs to arrange 2 to 3 circles of frozen drilling holes, and the minimum distance between the two drilling holes can be about 1.2 meters. There are dozens or even hundreds of frozen boreholes in one wellbore, and the depth of frozen boreholes at home and abroad does not exceed one thousand meters at present, so the movement of the drilling rig is very frequent. [0003] At present, in the frozen drilling construction of shaft shafts in coal mines, the general method of drilling rig movement is: first, use a jack to lift the entire drilling rig, place a roller bar under the base of the drilling rig, and use winch pulling and manual prying to perform translation. This way of moving is not only unsafe, but also time-consumi...
