Abstract

The invention discloses a clamp synchronous control system, a clamp device and a drilling machine in the technical field of clamp control. The clamp synchronous control system comprises an oil supply unit and synchronous control valve blocks; the oil supply unit is used for providing hydraulic oil required by work; and the synchronous control valve blocks are used for balancing the hydraulic oil flowing to each clamp so as to keep the synchronous movement of each clamping oil cylinder of each clamp. The synchronous control valve blocks are arranged between the oil supply unit and the clamp clamping oil cylinders, the synchronous control valve blocks are used for balancing hydraulic oil flowing to the clamps so as to keep synchronous movement of the clamping oil cylinders of the clamps, and the clamp synchronous control system has the advantage that the left oil cylinder and the right oil cylinder of the clamps can keep synchronous telescopic under the condition of different loads, and the problems that a threaded end of a drill rod is damaged during screwing-on and screwing-off, and the screwing-off efficiency is low are solved.

Description

technical field [0001] The invention belongs to the technical field of clamp control, and in particular relates to a clamp synchronous control system, a clamp device and a drilling machine. Background technique [0002] The multi-functional drilling rig is a kind of equipment used for foundation pit micropile, foundation pit support, water conservancy and hydropower engineering reinforcement, slope anchoring, pipe shed support, tunnel grouting, geological exploration, high-pressure rotary grouting and other constructions. The clamp device is an important part of the drilling rig, and it is also the most frequently used device in the construction process. At present, during the use of existing drilling rigs, the left and right cylinders of the clamps are out of sync and unable to maintain pressure, which not only damages the drill pipe, affects the efficiency of make-up and breakout, and causes construction accidents of rod drop, but also seriously affects the construction of...
