Abstract

The invention discloses a hydraulic drive drilling machine. The hydraulic drive drilling machine comprises an oil pump (12), wherein the oil pump (12) is connected with a three-position four-way electromagnetic valve (13) through an oil channel P; an oil channel A and an oil channel B of the three-position four-way electromagnetic valve (13) are connected with two ends of a hydraulic cylinder (14) respectively; an oil channel T of the three-position four-way electromagnetic valve (13) is connected with an oil tank; a proportional speed regulating valve (15) is connected to the oil channel B and is connected with a proportional valve control amplifier (16); the proportional valve control amplifier (16) is connected with a current transformer (17); the current transformer (17) is connected with a rotary rod motor (11) through a circuit. According to the hydraulic drive drilling machine, the equipment failure caused by overloading of a drill rod motor can be effectively prevented, and meanwhile, the drilling efficiency can be improved.

Description

technical field [0001] The invention relates to a horizontal directional drilling machine, in particular to a horizontal directional drilling machine which is driven by hydraulic pressure to feed the drilling rod. Background technique [0002] At present, with the gradual strengthening of the awareness of modern civilization and environmental protection, social problems, traffic problems and environmental pollution problems caused by excavating roads for various underground pipeline constructions have attracted more and more attention from the people. It will be introduced one after another, which provides a broad stage for trenchless horizontal directional drilling. When the existing horizontal directional drilling machine encounters a hard rock during the drilling process, the rotation of the drill pipe will slow down or even stop, causing the motor driving the drill pipe to be damaged or even burned. Contents of the invention [0003] The object of the present inventio...
