Abstract

The invention discloses a grouting device for well drilling. The purpose of automatic grouting of the interior of a drilling tool is achieved. The grouting device comprises a mechanical arm and a driving platform used for driving the mechanical arm, and further comprises a base hinged to the end, away from the driving platform, of the mechanical arm, a clamping structure and a grouting structure, wherein the clamping structure and the grouting structure are connected to the base; the clamping structure comprises a drilling tool gripper connected to the base and a first hydraulic cylinder used for driving the drilling tool gripper to be opened and closed; the grouting structure comprises a second hydraulic cylinder and a brush body; a cylinder barrel of the second hydraulic cylinder is connected with the base; the piston end of the second hydraulic cylinder is connected with a communicating piece; the brush body is arranged on the side, away from the second hydraulic cylinder, of the communicating piece; a grouting through hole is formed in the brush body; and a slurry channel communicating with the grouting through hole is formed in the communicating piece. The grouting device has the advantages of being easy to use, compact in structure, accurate in grouting, high in efficiency, capable of guaranteeing the safety of workers and the like.

Description

technical field [0001] The invention relates to the technical field of drilling, in particular to a grouting device for drilling. Background technique [0002] In drilling construction, there is usually a check valve connected to the bottom of the drilling tool. When the drilling tool is run in, in order to balance the internal and external pressure of the drilling tool, it is necessary to grout once in 10-15 columns of the drilling tool. The grouting process in the prior art is cumbersome. Long operation time, inaccurate filling measurement, large power consumption, and easy to induce overflow problem. Contents of the invention [0003] The object of the present invention is to provide a grouting device for drilling, which can achieve the effect of automatic grouting, and can realize the grasping and placement of drilling tools during the tripping process. [0004] The present invention realizes through following technical scheme: [0005] A grouting device for drilling...
