Description

Technical Field

[0001] This utility model relates to the field of pipeline hoisting technology, specifically a pipeline hoisting clamp. Background Technology

[0002] In industrial construction, municipal engineering, and energy transmission, the installation, maintenance, and handling of pipelines are common and critical tasks. Because pipelines are often heavy and long, manual handling is not only inefficient but also poses significant safety hazards. Therefore, lifting equipment is needed to complete these tasks, and lifting clamps are an important component of such equipment.

[0003] When using existing lifting clamps, the ropes are usually tied to the pipes manually before being placed into the lifting clamps for lifting operations. However, in actual use, it is not possible to quickly clamp and fix pipes of different sizes, and manually tying them with ropes increases the workload, thereby reducing the working efficiency of the lifting clamps.

[0004] Therefore, we urgently need to provide a pipe lifting clamp. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe hoisting clamp to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe hoisting clamp, comprising a base plate and a hook, wherein a hoisting structure is located above the base plate;

[0007] The hoisting structure includes a clamping mechanism and an auxiliary mechanism;

[0008] The clamping mechanism includes a connecting plate, a forward and reverse motor, a threaded rod, a moving plate, and a guide plate. The top of the connecting plate is connected to the bottom of the forward and reverse motor, the output end of the forward and reverse motor is connected to the top of the threaded rod, the outer wall of the threaded rod is threaded to the inner wall of the moving plate, one side of the moving plate is connected to one end of the guide plate, a movable block one is fixedly installed on one side of the moving plate, a movable plate is movably connected to the inner side of the movable block one, a movable block two is movably connected to one end of the movable plate, an adjusting plate is fixedly installed at the bottom of the movable block two, a connecting rod is fixedly installed on one side of the adjusting plate, and a clamping plate is fixedly installed at one end of the connecting rod.

[0009] A further improvement is that the connecting plate is U-shaped, and there are two guide plates symmetrically distributed at both ends of the moving plate. The connecting plate has a moving groove on its inner side, and one end of the guide plate is slidably connected to the inner wall of the moving groove, thereby enabling quick adjustment of the position of the moving plate, and thus quick adjustment of the position of the clamping plate.

[0010] A further improvement is that both the first and second movable blocks are U-shaped, and there are two movable plates symmetrically distributed on both sides of the connecting plate, which can quickly drive the adjustment plate to move and thus quickly adjust the position of the clamping plate.

[0011] A further improvement is that an adjustment groove is provided on the top of the base plate, and the bottom of the adjustment plate is slidably connected to the inner wall of the adjustment groove. There are two clamping plates, which are symmetrically distributed at both ends of the base plate, so that pipes of different sizes can be quickly clamped and fixed, thereby enabling better hoisting work.

[0012] A further improvement is that the auxiliary mechanism includes an adjustment box, a dividing plate, a sliding plate, a fixed rod, and a limiting rod. The inner wall of the adjustment box is connected to both ends of the dividing plate, and the inner wall of the adjustment box is slidably connected to both ends of the sliding plate. One side of the sliding plate is connected to one end of the fixed rod, and one end of the fixed rod is connected to one side of the limiting rod.

[0013] A further improvement is that a spring is fixedly installed between one side of the sliding plate and one side of the dividing plate, the limiting rod is L-shaped, and there are two limiting rods. The limiting rods are symmetrically distributed at both ends of the adjusting box, so that the position of the limiting rods can be quickly adjusted, thereby further clamping and fixing the pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This pipe lifting clamp utilizes a clamping mechanism that uses a forward and reverse motor to rotate a threaded rod, thereby moving a movable plate. Combined with the linkage of components such as the movable block and movable plate, the position of the clamping plate can be quickly adjusted. Simultaneously, the sliding of the guide plate within the moving groove of the connecting plate ensures the smooth movement of the movable plate, allowing the two symmetrically distributed clamping plates to move closer or further apart flexibly. Furthermore, the sliding of the adjusting plate within the adjusting groove of the base plate enables the clamp to quickly and easily adapt to pipes of different sizes, achieving stable clamping of the pipe without the need for manual rope binding, significantly reducing workload and effectively improving the working efficiency of the lifting clamp.

[0017] 2. This pipe hoisting clamp utilizes the elastic force of springs through an auxiliary mechanism. The sliding plate can drive the fixed rod and limit rod to move flexibly. Two symmetrical L-shaped limit rods can further clamp and fix the pipe, forming a double fixing effect in conjunction with the clamping mechanism. This significantly enhances the stability of the pipe during hoisting, reduces the risk of pipe slippage, and ensures the safety of hoisting operations. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] Example 1: A pipe hoisting clamp includes a base plate 1 and a hook 2, with a hoisting structure above the base plate 1;

[0026] The hoisting structure includes a clamping mechanism 3 and an auxiliary mechanism 4;

[0027] The clamping mechanism 3 includes a connecting plate 301, a forward and reverse motor 302, a threaded rod 303, a moving plate 304, and a guide plate 305. The top of the connecting plate 301 is connected to the bottom of the forward and reverse motor 302. The output end of the forward and reverse motor 302 is connected to the top of the threaded rod 303. The outer wall of the threaded rod 303 is threadedly connected to the inner wall of the moving plate 304. One side of the moving plate 304 is connected to one end of the guide plate 305. A movable block 306 is fixedly installed on one side of the moving plate 304. A movable plate 307 is movably connected to the inner side of the movable block 306. A movable block 308 is movably connected to one end of the movable plate 307. An adjusting plate 309 is fixedly installed at the bottom of the movable block 308. A connecting rod 310 is fixedly installed on one side of the adjusting plate 309. A clamping plate 311 is fixedly installed at one end of the connecting rod 310.

[0028] In this embodiment, the connecting plate 301 is U-shaped, and there are two guide plates 305. The guide plates 305 are symmetrically distributed at both ends of the moving plate 304. A moving groove is provided on the inner side of the connecting plate 301. One end of the guide plate 305 is slidably connected to the inner wall of the moving groove, so that the position of the moving plate 304 can be quickly adjusted, and the position of the clamping plate 311 can be quickly adjusted.

[0029] Furthermore, both movable block 1 306 and movable block 2 308 are U-shaped, and there are two movable plates 307. The movable plates 307 are symmetrically distributed on both sides of the connecting plate 301, which can quickly drive the adjusting plate 309 to move, and thus quickly adjust the position of the clamping plate 311.

[0030] Furthermore, an adjustment groove is provided on the top of the base plate 1, and the bottom of the adjustment plate 309 is slidably connected to the inner wall of the adjustment groove. There are two clamping plates 311, which are symmetrically distributed at both ends of the base plate 1, so that pipes of different sizes can be clamped and fixed quickly, thereby enabling better hoisting work.

[0031] When pipeline hoisting is required, the operator connects the hoisting clamp to the external hoisting equipment via hook 2. Starting the forward / reverse motor 302 (e.g., model 5IK120RGU-CF) rotates the threaded rod 303, which in turn moves the movable plate 304. The movement of the movable plate 304 causes the guide plate 305 to slide inside the connecting plate 301, increasing the stability of the movable plate 304's movement. The movement of the movable plate 304 then moves the movable block 306, which in turn moves the movable plate... The movable plate 307 moves, driving the movable block 308 to move. The movable plate 307 can swing between the movable block 306 and the movable block 308. The movement of the movable block 308 drives the adjustment plate 309 to move, which in turn drives the connecting rod 310 to move. The movement of the connecting rod 310 drives the clamping plate 311 to move, thereby quickly adjusting the position of the clamping plate 311. This allows for the quick clamping and fixing of pipes of different sizes. Furthermore, the auxiliary mechanism 4 can further clamp and fix the pipes, thus enabling better hoisting operations.

[0032] Example 2: Based on Example 1, the auxiliary mechanism 4 includes an adjustment box 401, a dividing plate 402, a sliding plate 403, a fixed rod 404, and a limiting rod 405. The inner wall of the adjustment box 401 is connected to both ends of the dividing plate 402. The inner wall of the adjustment box 401 is slidably connected to both ends of the sliding plate 403. One side of the sliding plate 403 is connected to one end of the fixed rod 404. One end of the fixed rod 404 is connected to one side of the limiting rod 405.

[0033] In this embodiment, a spring is fixedly installed between one side of the sliding plate 403 and one side of the dividing plate 402. The limiting rod 405 is L-shaped and there are two limiting rods 405. The limiting rods 405 are symmetrically distributed at both ends of the adjusting box 401, so that the position of the limiting rods 405 can be quickly adjusted, thereby further clamping and fixing the pipe.

[0034] Furthermore, the top of the base plate 1 is connected to the bottom of the hook 2, the top of the base plate 1 is connected to the bottom of the connecting plate 301, and the bottom of the base plate 1 is connected to the top of the adjusting box 401.

[0035] When pipe hoisting is required, the operator connects the hoisting clamp to the external hoisting equipment via hook 2. By activating the clamping mechanism 3, the position of the clamping plate 311 can be quickly adjusted, thereby quickly clamping and fixing pipes of different sizes. At this time, by pulling the limit rod 405, the fixed rod 404 is moved, and the sliding plate 403 slides on the inner wall of the adjusting box 401. The sliding plate 403 stretches the spring, thereby quickly adjusting the position of the limit rod 405. After the limit rod 405 is inserted into the inside of the pipe, the limit rod 405 is released, and the spring force resets the limit rod 405, thereby further clamping and fixing pipes of different sizes, effectively increasing the stability during hoisting and improving the hoisting work.
