Description

Technical Field

[0001] The utility model belongs to the technical field of tool equipment and relates to a portable chain clamp. Background Art

[0002] In pipeline operations, it is often necessary to use chain pliers to rotate the pipeline in order to facilitate the removal and installation of the pipeline. The tubular chain pliers commonly used in the market are bulky and inconvenient to carry. In addition, they are inefficient, time-consuming and laborious in actual use, and are not conducive to the unscrewing and unloading of drilling tubulars. There are also lighter and easier to carry chain pliers wrenches on the market, but their prices are relatively high. There are also some chain pliers with simpler structures. Although they are cheap, the chain pliers cannot effectively clamp the pipeline and the use effect is not good. Utility Model Content

[0003] The utility model aims to provide a portable chain clamp with a simple structure and good use effect in view of the problem that the existing chain clamps in the background technology have poor use effect.

[0004] To this end, the utility model adopts the following technical solutions:

[0005] A portable chain clamp comprises a tube body with a blocking structure at the front end, the cross section of the tube body is a rectangular structure, the side wall of the tube body is provided with a slide groove along the length direction of the tube body, a hook is provided in the slide groove, and the hook can move along the length direction of the slide groove, a chain is connected to the side of the tube body close to the front end and away from the slide groove, a pulley is fixed to the front end of the tube body, and the middle part of the chain passes around the pulley.

[0006] Furthermore, a slider which is adapted to the tube body and has a rectangular structure is provided in the tube body, and the slider can move inside the tube body along the length direction of the tube body. The hook is fixed on the slider, and a screw is provided in the tube body along the length direction of the tube body. The screw passes through the rear end of the tube body, and a screw hole is provided on the slider, and the screw passes through the screw hole.

[0007] Furthermore, a handle is provided at the rear end of the tube body.

[0008] Furthermore, the outer end of the screw rod is provided with a knob for rotating the screw rod.

[0009] The beneficial effects of the utility model are: a movable hook is arranged on the pipe body, and the hook is driven by a screw rod and a slider, the chain can be tightened by the hook, so as to ensure the clamping effect of the chain on the pipe fitting, effectively prevent slipping during rotation, and have a good use effect; the structure is simple, the volume is small, and it is easy to carry.

[0014] The utility model is described in detail below with reference to the accompanying drawings:

[0015] like Figure 1 and 2 As shown, a portable chain clamp comprises a tube body 1 with a blocking structure at the front end, the cross section of the tube body 1 is a rectangular structure, and a square structure is adopted in this embodiment, the side wall of the tube body 1 is provided with a slide groove 2 along the length direction of the tube body 1, and a hook 3 is provided in the slide groove 2, and the hook 3 can move along the length direction of the slide groove 2. Specifically, a slider 4 which is adapted to the tube body 1 and has a rectangular structure is provided in the tube body 1, and the slider 4 can move in the tube body 1 along the length direction of the tube body 1, and the hook 3 is fixed on the slider 4, and a screw 5 is provided in the tube body 1 along the length direction of the tube body 1, and the screw 5 passes through the rear end of the tube body 1, and the slider 4 A screw hole 6 is provided on the top, which passes through the slider 4. The screw rod 5 passes through the screw hole 6. The screw rod 5 and the slider 4 form a screw nut substructure. The slider 4 can be driven to move along the length direction of the tube body 1 by rotating the screw rod 5. A chain 7 is connected to the side of the tube body 1 close to the front end and away from the slide groove. The chain 7 can adopt the existing conventional bicycle chain. A pulley 8 is also fixed to the front end of the tube body 1. The middle part of the chain 7 is passed around the pulley 8. After the chain 6 is passed around the pulley 7, the corresponding position of the chain 7 is hooked using the hook 3, so that the pipe fitting can be clamped by the chain 7, and then the pipe fitting can be rotated for operation.

[0016] For practical convenience, a handle 9 is provided at the rear end of the tube body 1 , and a knob 10 for rotating the screw rod 5 is provided at the outer end of the screw rod 5 .

[0017] The usage of the utility model is as follows:

[0018] First, the screw rod 5 is turned by the handle to move the slider 4 and the hook 3 to the front end of the tube body 1, and the front end of the tube body 1 connected to the chain 7 is pressed against the pipe fitting 11, and then the chain 7 is passed around the pipe fitting, and the chain 7 is passed around the pulley 8 at the same time, and then the chain 7 is tightened, and the hook 3 is hooked at the position corresponding to the chain 7, and then the screw rod 5 can be turned by the handle to move the slider 4 and the hook 3 to the rear end of the tube body 1, so that the chain 7 tightens the pipe fitting 11 (such as Figure 3As shown), ensure that there is sufficient friction between the chain 7 and the pipe 11, effectively prevent the pipe 11 from slipping when rotating, and prevent the surface of the pipe 11 from being worn. Finally, the pipe body 1 can be rotated by the handle 9, and then the pipe 11 can be rotated by the chain 7 to complete the operation.

[0019] The chain clamp has a simple structure, a small size, and is easy to carry. At the same time, the pipe fitting can be effectively clamped by the chain, is not easy to slip, and has a good use effect.
