Description

Technical Field

[0001] This utility model relates to the field of pipeline transportation technology, and in particular to a hoisting clamp for transporting long pipes. Background Technology

[0002] In modern industry, the transportation and hoisting of long pipelines are important parts of many production processes. The limitations of their length and weight pose many challenges to traditional transportation methods. Traditional hoisting methods mostly use simple chains, slings or other fixing devices, but these methods have certain limitations in terms of safety, adaptability and work efficiency.

[0003] First, traditional lifting clamps are prone to causing long pipes to tilt or slip during lifting, increasing safety hazards at the construction site. Second, existing lifting clamps usually lack sufficient adjustment functions and cannot adapt to pipes of different diameters and weights, limiting their application range. This is especially true in complex construction environments where the ability to flexibly adjust clamps to adapt to different conditions is becoming increasingly important. In addition, the structural design of traditional clamps is often relatively simple, lacking comprehensive support and protection for the pipes, which can easily lead to the pipes being squeezed or scratched during transportation, thus affecting their service life.

[0004] Therefore, there is an urgent need for a new type of lifting clamp to solve the above problems. To this end, we propose a lifting clamp for transporting long pipes. Utility Model Content

[0005] The purpose of this utility model is to provide a hoisting clamp for transporting long pipes, so as to solve the problems of weak clamping capacity, weak adaptability and stability of existing hoisting clamps, as well as the easy squeezing or scratching of pipes during the hoisting process.

[0006] To solve the above-mentioned technical problems, this utility model provides a lifting clamp for transporting long pipes, including clamping arms, a pair of clamping arms, each including an adjustment groove, and a supporting pipe support disposed at the bottom of the clamping arm, the supporting pipe support being used to jointly support the long pipe.

[0007] The connecting rod includes a fixed rod, the two ends of which are hinged to the clamping arm by bolts and the position of the fixed rod is fixed. The connecting rod also includes an adjusting rod, which is slidably hinged to the adjusting grooves on both sides.

[0008] An adjusting screw is provided between a fixed rod and an adjusting rod, and fasteners are provided around the adjusting screw for adjusting the arm extension angle of the clamping arm;

[0009] Long pipe.

[0010] Preferably, the fixing rod includes a lifting hole at its top for connecting with the hook of the crane for lifting, and a threaded hole through the center of the fixing rod, with a receiving cavity above the threaded hole.

[0011] Preferably, the adjusting rod has a limiting hole at its center, and the adjusting rod is slidably hinged to the adjusting grooves on both sides by bolts.

[0012] Preferably, the adjusting rod further includes a top support disposed at its bottom, the top support and a pair of supporting pipe supports together wrapping around the long pipe;

[0013] The contact surfaces between the top support and the support pipe and the long pipe are non-slip surfaces.

[0014] Preferably, one end of the adjusting screw is fixed inside the adjusting rod through a limiting hole, and the other end extends out of the accommodating cavity through a threaded hole and is locked by a fastener.

[0015] Compared with the prior art, the lifting clamp of this utility model for transporting long pipes connects the clamping arms on both sides via a connecting rod, and controls and locks the arm extension angle of the clamping arms by adjusting the screw. Simultaneously, the long pipe is supported and locked by a support pipe bracket and a top bracket together, and finally locked with fasteners. A truss hook is used to pass through the lifting hole for lifting and transportation. Specifically, it has the following beneficial effects:

[0016] 1. The clamping arm's extension angle is controlled by adjusting the screw, allowing for precise adjustment based on the actual pipe diameter. This ensures the pipe is fully in contact with the support pipe bracket and top support, and is finally locked with fasteners, guaranteeing stability during hoisting and reducing the risk of tilting and slippage, thereby significantly improving the safety of the construction site.

[0017] 2. The support pipe bracket and top bracket adopt an arc-shaped design, which can provide comprehensive and uniform support for the pipeline, prevent squeezing or scratching during transportation, reduce the possibility of pipeline damage, and extend the service life of the pipeline.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0025] This utility model provides a lifting clamp for transporting long pipes. Please refer to [link / reference]. Figures 1-3The system includes a clamping arm 1, which is a pair, including an adjusting groove 101 and a support pipe support 102 disposed at the bottom of the clamping arm 1, the support pipe support 102 being used to jointly support the long pipe 4; a connecting rod 2, which includes a fixed rod 201, the two ends of which are hinged to the clamping arm 1 by bolts, the fixed rod 201 being fixed in position, and the connecting rod 2 also includes an adjusting rod 202, the adjusting rod 202 being slidably hinged to the adjusting grooves 101 on both sides; an adjusting screw 3, which is disposed between the fixed rod 201 and the adjusting rod 202, and a fastener 301 is disposed around the adjusting screw 3 for adjusting the arm extension angle of the clamping arm 1; and the long pipe 4.

[0026] The fixed rod 201 includes a lifting hole 201a at its top for connecting with the hook of a crane for lifting. A threaded hole 201b passes through the center of the fixed rod 201, and a receiving cavity 201c is provided above the threaded hole 201b. The adjusting rod 202 has a limiting hole 202a at its center and is slidably hinged to the adjusting grooves 101 on both sides by bolts. The adjusting rod 202 also includes a top support 202b at its bottom, which, together with a pair of support pipe supports 102, encloses the long pipe 4. The contact surfaces of the top support 202b and the support pipe supports 102 with the long pipe 4 are anti-slip surfaces. One end of the adjusting screw 3 is fixed in the adjusting rod 202 through the limiting hole 202a, and the other end protrudes from the receiving cavity 201c through the threaded hole 201b and is locked by fasteners 301.

[0027] It should be noted that, as Figure 1 As shown, the clamping arms 1 are symmetrically distributed with respect to the connecting rod 2. The clamping arms 1 are connected by a fixed rod 201 at the top and an adjusting rod 202 at the bottom. The fixed rod 201 is hinged to the clamping arms 1 through hinge holes and hinge bolts at both ends. The clamping arms 1 can rotate circumferentially around the hinge holes. Similarly, the adjusting rod 202 is slidably hinged to the adjusting groove 101 on the clamping arm 1. By changing the position of the fastener 301 in the adjusting screw 3, the distance between the fixed rod 201 and the adjusting rod 202 can be adjusted, thereby changing the arm span angle of the clamping arms 1. The closer the distance between the two, the larger the arm span angle between the clamping arms 1, which can accommodate longer pipes with larger diameters, and vice versa.

[0028] Preferably, the adjusting screw 3 is simultaneously inserted into both the threaded hole 201b and the limiting hole 202a. The position between the adjusting screw 3 and the limiting hole 202a is relatively fixed. The limiting hole 202a has no threads. The bottom of the adjusting screw 3 has a circular protrusion that inserts into the slot in the limiting hole 202a, ensuring that the adjusting screw 3 does not disengage from the limiting hole 202a but is limited by it. It can rotate axially within the limiting hole 202a. With this structure, the position of the adjusting rod 202 is always parallel to the fixed rod 201, and the bolts on both sides used to connect with the adjusting groove 101 are always at the same height. When it is necessary to adjust the opening between the clamping arms 1, the fastener 301 is loosened, and the adjusting screw 3 is rotated towards the threaded hole 201b. Tighten and adjust the distance between the fixing rod 201 and the adjusting rod 202. The design of the receiving cavity 201c allows the adjusting screw 3 to have a certain protrusion margin. The through threaded hole 201b can be further adjusted. After the included angle of the clamping arm 1 is increased, the long pipe can be inserted. Place the center of the long pipe in the clamp, and then decrease the included angle of the clamping arm 1 so that the support pipe support 102 and the top support 202b are completely in contact with the long pipe 4. Finally, tighten the fastener 301. The fastener 301 uses a pair of high-strength nuts. After the long pipe is locked, use a tool to tighten the high-strength nuts toward the threaded hole 201b. The tightening force will act around the pipe, so that the support pipe support 102 and the top support 202b are clamped to the long pipe 4. After tightening, use the second nut to lock it.

[0029] Preferably, the outer surfaces of the top support 202b and the supporting pipe support 102 are anti-slip surfaces, using rubber or metal coatings, which can improve anti-slip performance and wear resistance, prevent the pipe from sliding on the pipe support, and strengthen the clamping force.

[0030] In summary, this utility model's lifting clamp for transporting long pipes connects two clamping arms via a connecting rod. The arm extension angle is controlled and locked by adjusting screws. A support pipe bracket and a top bracket together wrap around the long pipe for support and locking. Finally, fasteners are used for locking, and a truss hook is used to lift and transport the pipe through the lifting hole. The clamping arm extension angle is controlled by adjusting screws, allowing for precise adjustment according to the actual diameter of the pipe. This ensures the pipe is completely in contact with the support pipe bracket and top bracket, and the fasteners ensure stability during lifting, reducing the risk of tilting and slippage, thus significantly improving safety at the construction site. The curved design of the support pipe bracket and top bracket provides comprehensive and even support for the pipe, preventing damage caused by squeezing or scratching during transportation, reducing the risk of pipe damage, and extending the pipe's service life.

[0031] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
