Description

Technical Field

[0001] This utility model relates to the field of search and rescue device manufacturing technology, and in particular to a lightweight insulated guide pipe hoisting clamp. Background Technology

[0002] Lightweight insulated air guide pipes are commonly used in building ventilation, central air conditioning systems, or industrial equipment. Their core function is to transport air while minimizing temperature loss during transport. "Lightweight" refers to their material, typically aluminum foil, composite fiberglass, etc., making them relatively lightweight. "Insulation" refers to the internal or external lining of the pipe with layers of insulation materials such as glass wool or rock wool for thermal insulation. "Air guide" clearly defines their function of directing airflow. Because their external insulation layer is relatively soft and easily damaged, and their overall structural strength is not high, special care must be taken during handling and installation. Ordinary metal lifting tools or ropes should not be used for direct binding, otherwise the insulation layer is easily flattened, torn, or detached.

[0003] In the field of building and industrial equipment installation, the hoisting and transportation of lightweight insulated diversion pipes has always been plagued by low operational efficiency and easy damage to the insulation layer. Traditional hoisting tools often use rigid clamping or rope fixing methods, which are not only cumbersome to adjust and difficult to control the clamping force, but also prone to deformation and damage to the insulation structure due to pipe surface slippage or pressure concentration during hoisting.

[0004] Therefore, how to provide a lightweight, insulated, and diverting pipe hoisting fixture is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a lightweight insulated guide pipe hoisting clamp. This clamp adopts a hydraulic drive and multi-link linkage structure to achieve rapid centering and stable release. Its adaptive pipe diameter hinged lever design can disperse clamping pressure and effectively protect the insulation layer. The limiting sliding structure ensures stable movement. The overall design is lightweight and simple, significantly improving hoisting efficiency and safety, thereby solving the problems mentioned in the background art.

[0006] A lightweight thermal insulation guide pipe hoisting clamp according to an embodiment of the present utility model includes a top plate. A lifting lug is fixedly connected to the middle of the top of the top plate. A hook is provided inside the lifting lug. Pins are fixedly connected to both the left and right sides of the top plate. A first connecting rod and a second connecting rod are hinged to the outer wall of each pin. A connecting shaft is rotatably connected between the outer walls of the ends of the first connecting rods away from the pins. A second connecting block is fixedly connected to the middle of the outer wall of the first connecting shaft. First connecting blocks are fixedly connected to both sides of the outer wall of the first connecting shaft. A limit sliding block is fixedly connected to the top of the outer wall of the first connecting block.

[0007] As a preferred embodiment of this utility model: a second connecting shaft is rotatably connected between the outer wall of the end of the second connecting rod away from the pin, and a hinge rod is provided on the side of the second connecting rod away from the fixed block.

[0008] As a further preferred embodiment of this utility model: the second connecting shaft is rotatably connected to the first hinge rod, and the end of the first hinge rod away from the second connecting shaft is fixedly connected to the second clamping plate.

[0009] As a further preferred embodiment of this utility model: both sides of the outer wall of the connecting shaft are fixedly connected to a fixed long strip plate, and a limit sliding groove is provided at the bottom end of the fixed long strip plate.

[0010] As a further preferred embodiment of this utility model: the inner wall of the limiting sliding groove is slidably connected to the limiting sliding block, and a fixing block is fixedly connected to the middle of the outer wall of the connecting shaft.

[0011] As a further preferred embodiment of this utility model: a hydraulic rod is fixedly connected to the front end of the fixing block, and a second connecting block is fixedly connected to the output end of the hydraulic rod.

[0012] As a further preferred embodiment of this utility model: the middle part of the outer wall of the connecting shaft is fixedly connected to the second connecting block, and the left and right sides of the outer wall of the connecting shaft are hinged with hinge rods.

[0013] As a further preferred embodiment of this utility model: the end of the second hinge rod away from the first connecting shaft is fixedly connected to a clamping plate, and the second hinge rod is hinged to the first hinge rod at the intersection of the two hinge rods.

[0014] The beneficial effects of this utility model are: This lifting clamp, through the ingenious combination of hydraulic drive and multi-link linkage structure, achieves rapid centering, clamping, and smooth release of the guide pipe. Its articulated lever design can adapt to different pipe diameters and distribute clamping pressure, effectively avoiding damage to the insulation layer caused by local stress.

A lifting lug 3 is fixedly connected to the center of the top of the top plate 1. A hook 2 is provided inside the lifting lug 3. Pins 17 are fixedly connected to both sides of the top plate 1. A first connecting rod 4 and a second connecting rod 16 are hinged to the outer wall of each pin 17. A connecting shaft 9 is rotatably connected between the outer wall of the end of the first connecting rod 4 away from the pin 17. A second connecting block 13 is fixedly connected to the center of the outer wall of the first connecting shaft 9. First connecting blocks 8 are fixedly connected to both sides of the outer wall of the first connecting shaft 9. A limit sliding block 19 is fixedly connected to the top of the outer wall of the first connecting block 8. A connecting shaft 15 is rotatably connected between the outer wall of the end of the second connecting rod 16 away from the pin 17. A hinge rod 7 is provided on the side of the second connecting rod 16 away from the fixed block 5. The second connecting shaft 15 and the hinge rod 7 are rotatably connected. The hinge rod 7 is located away from the connecting shaft 17. One end of the connecting shaft 15 is fixedly connected to a clamping plate 12. Both sides of the outer wall of the connecting shaft 15 are fixedly connected to a fixed long strip plate 14. The bottom end of the fixed long strip plate 14 is provided with a limiting sliding groove 20. The inner wall of the limiting sliding groove 20 is slidably connected to the limiting sliding block 19. A fixing block 5 is fixedly connected to the middle of the outer wall of the connecting shaft 15. A hydraulic rod 6 is fixedly connected to the front end of the fixing block 5.

[0021] Working principle: First, the top of the top plate 1 is moved to the top of the guide pipe to be clamped and moved by the lifting equipment of the hook 2. Then, the hydraulic rod 6 is activated. The retraction of the hydraulic rod 6 drives the second connecting block 13 to move. The movement of the second connecting block 13 drives the connecting shaft 9 on the inner wall to move. The movement of the connecting shaft 9 drives the hinge rods 10 and the first connecting rod 4 on both sides of the outer wall to rotate. The hinge between the hinge rod 10 and the hinge rod 7 can drive the clamping plates 11 and 12 at the bottom of the hinge rod 10 and the hinge rod 7 to clamp the guide pipe. This can quickly clamp the guide pipe and drive it to move. Conversely, by activating the hydraulic rod 6 to extend forward, the second connecting block 13 is moved, thereby releasing the clamping of the guide pipe.
