[0002] A drilling rig is a mechanical equipment that drives a drill string to drill underground in geological exploration to obtain physical geological data, also known as a drilling machine. Its main function is to drive the drill string to break the rock at the bottom of the hole, lower or raise the drill string in the hole, and can be used to drill core, ore core, rock chips, gaseous samples, liquid samples, etc. The gaseous samples and liquid samples need to be safely discharged to maintain the gas environment in the underground mine. At the same time, for the sake of improving safety, it is necessary to remotely control the drilling rig to move in the mine. Generally, a complete hydraulic system is required to control the walking of the drilling rig.

[0003] The existing hydraulic system of the drilling rig is controlled by a manual variable method. There are problems such as control lag in manual variable control, low accuracy angle during control, and low accuracy of the sluggish hydraulic system. For this reason, we have proposed a control system for a drilling rig crawler to walk. Content of the Utility Model
