Description

Technical Field

[0001] This utility model belongs to the field of engineering transportation. Specifically, this utility model relates to a hoisting clamp structure. Background Technology

[0002] In the field of engineering transportation, clamps and fixtures are mainly used to transport products. During the hoisting process, the cement lining coating on the inner wall of the pipe is subjected to stress, which causes surface defects, increases the amount of repair work for the cement lining coating, increases production costs, and affects the surface appearance quality of the cement lining coating.

[0003] A search revealed that Chinese patent CN222665157U, published on March 25, 2025, discloses a tool for clamping and lifting hot-rolled H-beam mechanical samples. The tool includes an L-shaped rod detachably mounted on the front outer wall of a lifting clamp. A fixing rod is movably mounted on the right end of the L-shaped rod, and a mounting groove is formed on the left end of the fixing rod. A connecting rod is fixed to the right end of the L-shaped rod and movably mounted within the mounting groove. A handle is fixed to the right end of the fixing rod. This invention facilitates accurate and rapid clamping of high-temperature steel sections using the L-shaped rod, fixing rod, and handle, improving work efficiency. However, during lifting, the tool may clamp onto the inner wall of the pipe, potentially causing damage to the inner wall due to stress. Utility Model Content

[0004] The present invention aims to provide a hoisting clamp structure for protecting the inner wall of pipe fittings.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A hoisting clamp structure includes a fixed bracket, a first hanging plate at one end of the fixed bracket, a second hanging plate at the other end of the fixed bracket, a first clamping plate at the bottom of the first hanging plate, a second clamping plate at the bottom of the second hanging plate, and a pipe fitting between the first clamping plate and the second clamping plate.

[0007] One end of the fixed bracket is provided with a first through groove, and the first hanging plate is provided in the first through groove. The other end of the fixed bracket is provided with a second through groove, and the second hanging plate is provided in the second through groove.

[0008] One side of the fixed bracket and the first hanging plate are connected by a first pin, and the other side of the fixed bracket and the second hanging plate are connected by a second pin.

[0009] The fixed bracket has a first through hole on one side, and the first pin is located in the first through hole. The fixed bracket has a second through hole on the other side, and the second pin is located in the second through hole. Multiple sets of the first and second through holes are provided.

[0010] The first hanging plate has a third through hole at its end, and the second hanging plate has a fourth through hole at its end. Both the third and fourth through holes are equipped with hooks.

[0011] Anti-slip pads are provided on the first and second clamping plates respectively.

[0012] The fixed bracket has a fixed block in the middle, and the fixed block has a fifth through hole.

[0013] The fixed bracket is square, the first hanging plate and the second hanging plate are both L-shaped, and the first clamping plate and the second clamping plate are arc-shaped.

[0014] Both the first and second hanging plates have chamfered edges.

[0015] The technical advantages of this invention are as follows: The first and second hanging plates are suspended by ropes or chains. Under the weight of the pipe fitting, the first and second hanging plates rotate via the first and second pins respectively, achieving clamping of the outer wall of the pipe fitting by the first and second clamping plates without damaging the inner wall, preventing surface defects, and reducing the workload of repairing the cement lining coating. By setting multiple sets of first and second through holes with different spacing, pipe fittings of different diameters can be clamped, saving costs. Furthermore, by setting anti-slip pads on the first and second clamping plates, the friction for clamping can be further increased. Attached Figure Description

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this utility model, and to facilitate its implementation.

[0021] like Figure 1 and Figure 2 As shown, a hoisting clamp structure includes a fixed bracket 1, a first hanging plate 2 at one end of the fixed bracket 1, and a second hanging plate 3 at the other end of the fixed bracket 1. A first clamping plate 4 is located at the bottom of the first hanging plate 2, and a second clamping plate 5 is located at the bottom of the second hanging plate 3. A pipe fitting 6 is located between the first clamping plate 4 and the second clamping plate 5. In this embodiment, the inner wall of the pipe fitting 6 is coated with a cement lining. The first hanging plate 2 and the second hanging plate 3 are suspended by ropes or chains. Under the weight of the pipe fitting 6, the first hanging plate 2 and the second hanging plate 3 rotate through the first pin 9 and the second pin 10 respectively, so that the first clamping plate 4 and the second clamping plate 5 clamp the outer wall of the pipe fitting 6 without damaging the inner wall of the pipe fitting 6, preventing surface defects, increasing the workload of repairing the cement lining coating, increasing production costs, and affecting the surface appearance quality of the cement lining coating.

[0022] One end of the fixed bracket 1 is provided with a first through groove 7, and a first hanging plate 2 is provided in the first through groove 7. The other end of the fixed bracket 1 is provided with a second through groove 8, and a second hanging plate 3 is provided in the second through groove 8. The first hanging plate 2 is provided in the first through groove 7, which allows the first hanging plate 2 to rotate. Similarly, the second hanging plate 3 is provided in the second through groove 8, which allows the second hanging plate 3 to rotate.

[0023] One side of the fixed bracket 1 is connected to the first hanging plate 2 via a first pin 9, and the other side of the fixed bracket 1 is connected to the second hanging plate 3 via a second pin 10. The first pin 9 passes through the through hole between the first hanging plate 2 and one side of the fixed bracket 1, enabling the rotation of the first hanging plate 2. The second pin 10 passes through the through hole between the second hanging plate 3 and the other side of the fixed bracket 1, enabling the rotation of the second hanging plate 3.

[0024] The fixed bracket 1 has a first through hole 11 on one side, and a first pin 9 is disposed in the first through hole 11. The fixed bracket 1 has a second through hole 12 on the other side, and a second pin 10 is disposed in the second through hole 12. Multiple sets of the first through hole 11 and the second through hole 12 are provided. In this embodiment, there are two of each of the first through hole 11 and the second through hole 12, which are used to adjust the position of the first hanging plate 2 and the second hanging plate 3. When the first hanging plate 2 and the second hanging plate 3 are moved to different positions, they can be connected by the pins to clamp pipes of different diameters 6. This allows one clamp to be used for multiple products, saving costs.

[0025] The first hanging plate 2 has a third through hole 13 at one end, and the second hanging plate 3 has a fourth through hole 14 at one end. Both the third through hole 13 and the fourth through hole 14 are equipped with hooks. The hooks are used to connect ropes or chains.

[0026] Anti-slip pads 15 are respectively provided on the first clamping plate 4 and the second clamping plate 5. By providing anti-slip pads 15 on the first clamping plate 4 and the second clamping plate 5 that contact the pipe fitting 6, the friction force used for clamping can be further increased.

[0027] The fixed bracket 1 has a fixed block 16 in the middle, and the fixed block 16 has a fifth through hole 17. The fixed bracket 1 has a fixed block 16, and the fixed block 16 has a fifth through hole 17. When the clamp is not in use, the fifth through hole 17 is used to suspend the clamp, which prevents it from occupying space and is safer.

[0028] The fixed bracket 1 is square, the first hanging plate 2 and the second hanging plate 3 are both L-shaped, and the first clamping plate 4 and the second clamping plate 5 are arc-shaped. The arc-shaped first clamping plate 4 and the second clamping plate 5 are used to clamp the pipe fitting 6. The outer wall shape of the pipe fitting 6 is the same as the shape of the clamping plate. When used to clamp the square pipe fitting 6, the shape of the clamping plate will also be square.

[0029] Both the first hanging plate 2 and the second hanging plate 3 are chamfered. The chamfering of the first hanging plate 2 and the second hanging plate 3 serves to reduce stress concentration.

[0030] The working principle of this utility model is as follows: A hoisting clamp structure includes a fixed bracket 1, a first hanging plate 2 at one end of the fixed bracket 1, a second hanging plate 3 at the other end of the fixed bracket 1, a first clamping plate 4 at the bottom of the first hanging plate 2, a second clamping plate 5 at the bottom of the second hanging plate 3, and a pipe fitting 6 between the first clamping plate 4 and the second clamping plate 5. The first hanging plate 2 has a third through hole 13, and the second hanging plate 3 has a fourth through hole 14. The third through hole 13 and the fourth through hole 14 are respectively connected to hooks. The hooks are connected to ropes or chains. The first hanging plate 2 and the second hanging plate 3 are suspended by ropes or chains. Under the action of the weight of the pipe fitting 6, the first hanging plate 2 and the second hanging plate 3 rotate through the first pin 9 and the second pin 10 respectively, so that the first clamping plate 4 and the second clamping plate 5 clamp the outer wall of the pipe fitting 6 without damaging the inner wall of the pipe fitting and preventing surface defects. When the lifting process is over and the clamp is not working, the fixing block 16 is provided with a fifth through hole 17 for suspending the clamp, which prevents space occupation and is safer. By providing anti-slip pads on the first clamping plate 4 and the second clamping plate 5, the friction for clamping can be further increased.
