The invention discloses a safety control device for regulating pressures of jaw vices of a horizontal directional drilling machine. The safety control device comprises a hydraulic system and an electric control system. The hydraulic system comprises a hydraulic pump (1), a hydraulic oil tank (16), a jaw vice pressure regulating electromagnetic valve (2), a front jaw vice clamping reset electromagnetic valve (3), a front jaw vice first cylinder (4), a front jaw vice second cylinder (5), a rear jaw vice first cylinder (6), a rear jaw vice second cylinder (7), a jaw vice rotary cylinder (8), a rear jaw vice clamping reset electromagnetic valve (9) and a jaw vice rotary reset electromagnetic valve (10), and the front vice jaw clamping reset electromagnetic valve, the rear jaw vice clamping reset electromagnetic valve and the jaw vice rotary reset electromagnetic valve can work under the control of the electric control system. The safety control device has the advantages that the safety control device is additionally provided with the jaw vice pressure regulating electromagnetic valve and a jaw vice pressure regulating knob, jaw vice oil supply modes can be reasonably arranged under the control of the electric control system, running speeds of the jaw vice cylinders can be changed as needed, accordingly, variable jaw vice clamping pressures and rotary torque can be provided, energy can be saved, and environments can be protected.
Description
technical field [0001] The invention relates to a safety control device for adjusting the pressure of a vise of a horizontal directional drilling rig, and belongs to the technical field of horizontal directional drilling rigs. Background technique [0002] Horizontal directional drilling rig is a construction machine that lays various underground utilities (pipelines, cables, etc.) without excavating the ground surface. In paving construction, it is suitable for sandy soil, clay, pebbles and other ground conditions, and it can be used for construction in most non-hard rock areas in my country. [0003] The vise for directional drilling is located at the front of the drilling rig and consists of front and rear vises. Both the front and rear vises can be pushed radially by the hydraulic cylinder to clamp the drill pipe. At the same time, the rear vise can be used under the action of the hydraulic cylinder The bottom and the front vise rotate relative to each other, and coopera...
