The invention relates to a method for utilizing a propelling beam and a support box structure of a drilling machine to arrange a hydraulic circuit. A drilling machine comprises a propelling beam assembly and a propelling beam assembly support box, the propelling beam assembly is mounted on the propelling beam assembly support box which is fixed on an excavator quick-changing mechanism, the excavator quick-changing mechanism is mounted on a small excavator arm, part of a hydraulic control valve group I is mounted inside the propelling beam assembly support box which is covered with a face plate with the lower end sealed, the hydraulic control valve group I is fixedly mounted inside the propelling beam assembly support box, the inside components are mutually connected through hydraulic pipes, systematic hydraulic oil pipes are all connected the hydraulic control valve group through a hydraulic pipe joint, and a hydraulic system pumping source is connected onto a control valve group through hard pipes and hoses. The control valve group is generally arranged near to an actuator, an actuator oil pipe is short, and a control valve block is mounted in a sealed propelling beam bracket and the propelling beam assembly support box, so that service life is prolonged, and reliability of the complete machine is improved due to the arrangement of the valve block.
Description
technical field [0001] The invention relates to a method for arranging hydraulic valve blocks and pipelines by using a drilling rig equipment propulsion beam and support box structure. Background technique [0002] At present, the hydraulic valves of the existing drilling rig equipment are mainly arranged in the excavator cabin, the drilling rig base or the boom, etc. The advantages of this arrangement are large installation space, flexible layout, and convenient installation. It is difficult to protect the valve block. Installing too many valve blocks on the boom will affect the strength of the boom. If the valve block is exposed on the boom, it will be easily covered by dust and water, reducing its service life and greatly affecting the reliability and use of the whole machine. life and increase maintenance costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for placing the hydraulic circuit by usi...
