Abstract

The invention discloses a motor-driven horizontal oriented drill rig. A rail (7) is arranged at the side surface of a base (5); a moving slider (8) matched with the rail (7) is arranged above the base (5); a moving motor (9) is arranged above the moving slider (8); a rack (10) parallel with the base is arranged above the base (5); the moving motor (9) is meshed with the rack (10) by a gear; a drill rod motor (11) is arranged above the moving slider (8); a drilling rod (12) is fixed at the output end of the drill rod motor (11) connected with a current transformer (13); the current transformer (13) is connected with an amplifier (14) connected with a motor controller (15); the motor controller (15) is connected with the moving motor (9). According to the motor-driven horizontal oriented drill rig, the equipment fault caused by overloading of the drill rod motor can be effectively prevented and the ground drilling efficiency can also be improved.

Description

technical field [0001] The invention relates to a horizontal directional drilling machine, in particular to a horizontal directional drilling machine which drives a drill rod to advance and rotate through a motor. 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...
