Leveling system based on laser distance measurement and method

Abstract

The invention discloses a leveling system based on laser distance measurement. The leveling system comprises a drilling machine assembly, a box body, a distance measurement assembly and a control assembly, the drilling machine assembly comprises a drilling machine platform and four linear driving pieces, output shafts of the four linear driving pieces are connected to the a portion below the drilling machine platform and are arranged in a rectangular shape, the box body is connected to the drilling machine platform, the distance measurement assembly is arranged in the box body and comprises a connecting rope, a rectangular pyramid and four laser distance measurement instruments, one end of the connecting rope is connected to the inner wall of the top of the box body, the tip end of the rectangular pyramid is connected to the other end of the connecting rope, the four laser distance measurement instruments are connected to the inner wall of the box body and are arranged in one-to-one correspondence with the four circumferential side faces of the rectangular pyramid, the control assembly comprises a processor, and the processor is electrically connected with the four distance measurement instruments and the four linear driving pieces. The output shafts of the linear driving pieces are controlled to stretch out or retract according to distance signals output by the laser distance measurement instruments, and therefore leveling of the drilling machine platform is achieved; and the problem that errors are large after leveling can be solved through the leveling system based on laser distance measurement.

Description

technical field [0001] The invention relates to the technical field of roller cone drilling machines, in particular to a leveling system and method based on laser ranging. Background technique [0002] Perforation blasting is a key process link in the mining process of open-pit mines, in which perforation is the premise of blasting, and the roller cone drilling rig is the most widely used perforation equipment in large-scale open-pit mines. In order to make the blasting effect meet the requirements of the mine, it is necessary to ensure the perforation quality of the blast hole. Therefore, during the perforation process of the roller cone drill, it is necessary to use four jacks arranged at the four corners of the roller cone drill to ensure the stability of the roller cone drill. Leveling allows the borehole to be drilled vertically. [0003] At present, the traditional drilling rig leveling device relies on tools such as the "level gauge" on the drilling rig, and uses the...
