Description

Technical Field

[0001] This utility model relates to the field of lifting beam technology, and in particular to a lifting beam with adjustable lifting points. Background Technology

[0002] A lifting beam is a specialized tool used to assist in lifting operations. It is typically made of metal and is usually beam-shaped. Its function is to distribute lifting forces more evenly, improving the stability and safety of the lifting process. It can also accommodate objects of different shapes and sizes and is widely used in construction, machinery manufacturing, and other fields.

[0003] Currently, the lifting points (lifting lugs) at the lower end of the lifting beam are mostly fixed, which makes it difficult to adjust the position of the lifting points flexibly, making it difficult to adapt to the needs of different lifting scenarios, and resulting in obvious limitations in usage scenarios and functions. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose an adjustable suspension beam.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A lifting lug is fixedly connected to the lower end of the connecting block. Multiple limiting grooves corresponding to the connecting blocks are arranged sequentially from left to right on the upper end of the suspension beam body. The inner top of the connecting block is located within the limiting groove. A support block is slidably connected to the inner sidewall of the connecting block. The support block is located at the lower end of the suspension beam body. Multiple arc-shaped grooves are provided on the upper end of the support block. A longitudinally arranged roller is provided in the arc-shaped groove. The front and rear ends of the roller are rotatably connected to the inner sidewall of the arc-shaped groove, respectively. The upper end of the roller passes through the arc-shaped groove. Multiple vertically arranged connecting rods are slidably inserted into the inner bottom of the support block. The upper end of the connecting rod is fixedly connected to the lower end of the support block. A spring is slidably sleeved on the connecting rod. The two ends of the spring abut against the lower end of the support block and the inner bottom of the connecting block, respectively.

[0007] Preferably, the inner wall of the connecting block has a ball groove, and a ball is rotatably connected to the inner wall of the ball groove, with a portion of the ball penetrating through the ball groove.

[0008] Preferably, a vertically arranged positioning rod is fixedly connected to the inner bottom of the limiting groove, and a positioning groove corresponding to the positioning rod is provided on the inner top of the connecting block, with the upper end of the positioning rod slidingly extending into the positioning groove.

[0009] Preferably, a rubber pad is fixedly connected to the outer side wall of the roller.

[0010] Preferably, there are four connecting rods arranged in a rectangular pattern.

[0011] Preferably, rubber strips are fixedly connected to both the front and rear sides of the connecting block.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, by setting a limiting groove, a positioning rod, a positioning slot, a connecting block, a connecting rod, a spring, and a support block, not only can the position of the lifting point be quickly adjusted, but it can also play a limiting role after adjustment to prevent displacement, thereby improving practicality and reliability. In this invention, by setting ball bearings and rollers, the resistance when the user adjusts the position is reduced, and the smoothness of operation is improved. This invention achieves rapid and flexible adjustment of the lifting point position while playing a limiting and anti-loosening role, effectively meeting the needs of diverse lifting scenarios and significantly improving the practicality of the product.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4An adjustable lifting beam includes a horizontally arranged lifting beam body 1, a U-shaped connecting block 2 slidably sleeved on the lifting beam body 1 for supporting the lifting lug, rubber strips 12 fixedly connected to both the front and rear sides of the connecting block 2 for anti-wear function on its outer wall, a lifting lug 6 fixedly connected to the lower end of the connecting block 2 for connecting the lifting rope, a ball groove on the inner side wall of the connecting block 2, and a ball 11 rollingly connected to the inner side wall of the ball groove to reduce the resistance when the connecting block 2 moves, with part of the ball 11 penetrating through the ball groove;

[0021] In this embodiment, the upper end of the lifting beam body 1 is provided with a plurality of limiting grooves 3 corresponding to the connecting block 2 from left to right, which are used to limit the connecting block 2. The inner top of the connecting block 2 is located in the limiting groove 3. The inner bottom of the limiting groove 3 is fixedly connected with a vertically arranged positioning rod 4, which is used to position the connecting block 2 and prevent it from shifting. The inner top of the connecting block 2 is provided with a positioning groove corresponding to the positioning rod 4. The upper end of the positioning rod 4 slides into the positioning groove.

[0022] In this embodiment, a support block 5 is slidably connected to the inner wall of the connecting block 2, which is used to cooperate with the spring 9 to give the connecting block 2 a downward elastic support force. The support block 5 is located at the lower end of the lifting beam body 1. The upper end of the support block 5 is provided with multiple arc-shaped grooves. The arc-shaped grooves are provided with longitudinally arranged rollers 7, which are used to reduce the resistance between the support block 5 and the lower wall of the lifting beam body 1 when the support block 5 moves with the connecting block 2. The front and rear ends of the rollers 7 are rotatably connected to the inner wall of the arc-shaped grooves respectively. The upper end of the rollers 7 passes through the arc-shaped grooves. A rubber pad 8 is fixedly connected to the outer wall of the rollers 7 to improve the wear resistance of the rollers 7.

[0023] In this embodiment, a plurality of vertically arranged connecting rods 10 are slidably inserted into the inner bottom of the support block 5 to guide the lifting and lowering of the support block 5. There are four connecting rods 10 in a rectangular distribution to maintain the stability of the support block 2 when it is lifted and lowered. The upper end of the connecting rod 10 is fixedly connected to the lower end of the support block 5. A spring 9 is slidably sleeved on the connecting rod 10 to provide elastic support for the connecting block 2. The two ends of the spring 9 abut against the lower end of the support block 5 and the inner bottom of the connecting block 2, respectively.

[0024] In this embodiment, the hoisting operation is first carried out by connecting the hoisting rope through the hoisting lug 6. If the position of the hoisting lug needs to be adjusted, the connecting block 2 is pushed upward so that its inner top is disengaged from the limiting groove 3. Then the connecting block 2 can be moved left and right to adjust the position of the hoisting lug 6. During this process, the ball bearing 11 and the roller 7 can significantly reduce the friction and resistance when the support block 5 and the connecting block 2 move on the lifting beam body 1, ensuring smooth movement. After the adjustment is completed, the connecting block 2 is released and falls under its own weight, re-embedding into the limiting groove 3 to avoid positional deviation. At the same time, the spring 9 provides elastic support to the support block 5, so that the upper end of the support block 5 is tightly attached to the lower end of the lifting beam body 1. The elastic force of the spring 9 pushes the connecting block 2 downward, further preventing it from falling out of the limiting groove 3, effectively improving reliability.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
