Abstract
The utility model discloses a clamping chuck of a gas drainage drilling machine. One side of a clamping chuck (4) is connected with a power head (1), and the other side of the clamping chuck (4) is connected with clamping chuck baffle plates (3) through a clamping chuck screw (2); and the clamping chuck (4) is made of leather materials. Compared with the conventional clamping chuck of the gas drainage drilling machine, the clamping chuck of the gas drainage drilling machine disclosed by the utility model ensures that the clamping chuck screw (2) can not be broken in the power head (1), thereby improving the operation efficiency.
Description
Technical field
The utility model relates to a kind of drill rig components, particularly a kind of chuck.
Background technology
Mining area former gas drainage drilling rig unit head chuck is made of round steel, the chuck screw is on unit head, when drilling, because that some excessive velocities crooked or that the operation driver drills of drilling rod is easy to the screw of chuck on unit head suppressed is disconnected, suppresses disconnected screw and in screw, be difficult to draw out.
Summary of the invention
Problem to be solved in the utility model is: a kind of gas drainage drilling rig chuck is provided, does not break on unit head so that the chuck screw can not be suppressed.
The technical solution of the utility model is: a kind of gas drainage drilling rig chuck, and chuck one side connects unit head, and opposite side links to each other with the chuck baffle plate by the chuck screw, and the material of chuck is leather.
The utility model is compared with the round steel chuck in past, and the chuck screw can not break in unit head, has improved operating efficiency.
Description of drawings
Fig. 1 is gas drainage drilling rig chuck structure schematic diagram.
The specific embodiment
