Technical Field

[0001] The utility model relates to the technical field of tube pulling machines, in particular to a tube pulling machine jaw device which is convenient for clamping. Background Art

[0002] The pipe pulling machine is a supporting auxiliary equipment for drilling rigs in various rock and soil drilling projects. It is suitable for projects that use pipe drilling technology such as cast-in-place piles, jet jet drilling, and anchor holes. It is used to pull out the borehole wall casing and drill rod;

[0003] CN210738504U discloses a pipe clamping device for a pipe pulling machine. The pipe clamping device for a pipe pulling machine is used in coordination with an equipment frame, an electric telescopic rod, an adjustment plate, a buffer block, an arc-shaped clamping block and a friction layer, so that the casing is fixed by the arc-shaped clamping blocks on both sides. The structure is simple and the operation is convenient, so the casing can be fixed quickly, which is beneficial to improving the working efficiency of the device. At the same time, the friction layer arranged on the inner wall of the arc-shaped clamping block helps to improve the friction between the arc-shaped clamping block and the casing, which helps to improve the clamping effect of the casing.

[0004] However, the above-mentioned tube pulling structure is difficult to clamp and position tubes of different diameters, so that only tubes of the same diameter can be clamped, thereby reducing the practicality of the clamping device. Utility Model Content

The hydraulic telescopic rods 110 work to raise the height position of the clamping component 300 to extract the clamped pipe;

[0032] Please continue reading Figure 1-3 The power component 200 is connected to the top of the hydraulic telescopic rod 110 to change the clamping inner diameter of the clamping component 300 to extract the cannulas of different sizes;

[0033] The power component 200 includes a connecting frame 210 threadedly connected to the top of the movable end of the hydraulic telescopic rod 110, and a servo motor 220 threadedly connected to the top of the connecting frame 210.

[0034] action:

[0035] The servo motor 220 works, driving the linkage gear set composed of the driving gear 221 and the driven gear 222 to move, thereby driving the double-headed screw 230 to rotate;

[0036] Please continue reading Figure 1-3 The clamping component 300 is connected to the power component 200 and moves synchronously with the power component 200 to clamp the cannula;
