Problems solved by technology

[0002] During the construction of horizontal directional drilling rig, the forward and backward operation of the hydraulic power head on the drill frame is usually powered by a single oil circuit. This oil supply method makes the propulsion power of the hydraulic power head smaller, so that the underground The driving force obtained by the drill bit is also small, and when the drill bit encounters hard soil, the advancing speed will become very slow, so that the working efficiency becomes very low

Abstract

The invention discloses a horizontal directional drill power head push-pull converging control system. A push-pull pump is respectively connected with a main relief valve (6) and a main push-pull valve (7), and the main relief valve (6) is respectively connected with a hydraulic oil tank (16) and a working solenoid valve (10); the working electromagnetic valve (10) is connected with a push-pull handle (4), and the push-pull handle (4) is respectively connected with a back pull solenoid valve (3), a back pull converging solenoid valve (2), a front push converging solenoid valve (5) and a main push-pull valve (7); the back pull solenoid valve (3) is connected with the back pull converging solenoid valve (2), and a back pull converging valve (12) and a front push converging valve (11) are connected with the main push-pull valve (7); the back pull converging solenoid valve (2) is respectively connected with the main push-pull valve (7) and the front push converging valve (12), and the front push converging solenoid valve (5) is connected with the front push converging valve (11). The horizontal directional drill power head push-pull converging control system provided by the invention can provide a push-pull motor with hydraulic closing oil, so that a push-pull power head has stronger power and higher rotating speed.

Description

technical field [0001] The invention relates to a hydraulic control system, in particular to a hydraulic confluence control system. Background technique [0002] During the construction of horizontal directional drilling rig, the forward and backward operation of the hydraulic power head on the drill frame is usually powered by a single oil circuit. This oil supply method makes the propulsion power of the hydraulic power head smaller, so that the underground The driving force obtained by the drill bit is also small, and when the drill bit encounters harder soil, the advancing speed will become very slow, so that the working efficiency becomes very low. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a push-pull confluence control system for the power head of a horizontal directional drilling rig, which can enhance the driving force of the power head on the drill frame, thereby improving work efficie...
