Description

Technical Field

[0001] This utility model relates to the field of permanent magnet lifter technology, and in particular to a tile-shaped permanent magnet lifter that can be adapted to various scenarios. Background Technology

[0002] As a high-efficiency and environmentally friendly lifting device, magnetic permanent magnet lifters are widely used in steel, machinery manufacturing, logistics and handling industries, especially suitable for lifting magnetic materials such as plates and profiles. Traditional lifters mostly use electromagnetic or permanent magnet structures, relying on magnetic attraction to move objects. However, in complex industrial scenarios, their stability and safety face challenges. For example, in high-temperature, vibration or dusty environments, the reliability of the lifter's operation and its ability to prevent accidental contact are insufficient, which can easily lead to safety accidents. In addition, the differences in shape and weight of different objects place higher demands on the adaptability of the lifter. In particular, the lack of buffer protection design can cause objects to be damaged by rigid collisions during lifting. Therefore, developing a tile-shaped magnetic permanent magnet lifter that can be adapted to multiple scenarios and has the functions of preventing accidental contact and buffering has become an important direction for improving operational safety and efficiency.

[0003] Existing magnetic permanent magnet lifters typically consist of a permanent magnet, magnetic poles, an operating handle, and a housing. Their working principle is to drive the internal magnetic system by rotating the handle, thereby changing the magnetic circuit state to achieve material suction or discharge. The positioning of the handle mostly relies on simple mechanical limits or friction braking.

[0004] The existing handle positioning mechanism of magnetic permanent magnet lifters has significant defects. The mechanical limit or friction braking method it relies on is prone to loosening or displacement in complex environments such as vibration and impact, causing the handle to accidentally leave the working position. For example, when the lifter is subjected to external vibration during transportation, traditional spring pins or threaded fasteners are prone to failure due to inertia, causing the handle to be accidentally switched to the demagnetized state, which may lead to the risk of the heavy object falling. This problem not only reduces the reliability of lifting operations, but also easily causes serious safety accidents. To solve the above problems, a tile-shaped magnetic permanent magnet lifter that can be adapted to various scenarios is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a tile-shaped magnetic permanent magnet lifter that can be adapted to various scenarios. It aims to improve the problem that the mechanical limiting or friction braking methods relied upon in the prior art are prone to loosening or displacement in complex environments such as vibration and impact, which can cause the handle to accidentally leave the working position.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tile-shaped magnetic permanent magnet lifter adaptable to various scenarios includes a lifter body, a hook on the top of the lifter body, a handle rotatably connected to the side wall of the lifter body, a positioning hole on the side wall of the lifter body, a fixing plate fixedly connected to the outer wall of the handle, a hollow column fixedly connected inside the fixing plate, and a positioning component inside the hollow column.

[0008] The positioning component includes a positioning column, which is slidably connected inside the hollow column. One end of the positioning column engages with the positioning hole. A T-slot is provided inside the hollow column. A locking rod plate is fixedly connected to the outer wall of the positioning column. A sliding plate is slidably connected inside the hollow column. A reset component is provided on the outer wall of the positioning column. A tile-shaped buffer pad is provided on the top of the lifting device body. The top of the tile-shaped buffer pad fits against the bottom of the lifting device body. A connecting component is provided inside the tile-shaped buffer pad.

[0009] As a further description of the above technical solution:

[0010] The reset assembly includes a spring, one end of which is fixedly connected to one side wall of the sliding disk, and the other end of which is fixedly connected to the inner wall of the hollow column.

[0011] As a further description of the above technical solution:

[0012] The connecting assembly includes a pin and a retaining ball. The pin is fixedly connected inside the corrugated buffer pad, the top of the pin is slidably connected inside the crane body, the retaining ball is slidably connected inside the pin, and the outer wall of the pin engages with the inside of the crane body.

[0013] As a further description of the above technical solution:

[0014] A fixing plate is fixedly connected inside the pin post, and a pressing post is slidably connected inside the fixing plate.

[0015] As a further description of the above technical solution:

[0016] A trapezoidal locking post is fixedly connected to the top of the pressing post, and a pressing cap is fixedly connected to the top of the pressing post.

[0017] As a further description of the above technical solution:

[0018] The trapezoidal locking post is slidably connected inside the pin post, and the side wall of the trapezoidal locking post is in contact with the outer wall of the locking ball.

[0019] As a further description of the above technical solution:

[0020] A second sliding disc is fixedly connected to the outer wall of the pressing column, and the second sliding disc is slidably connected to the inner wall of the pin column.

[0021] As a further description of the above technical solution:

[0022] A second spring is fitted on the outer wall of the pressing column. One end of the second spring is fixedly connected to the bottom of the fixed plate, and the other end of the second spring is fixedly connected to the top of the sliding plate.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the fixed plate and hollow column move synchronously by rotating the handle. When the handle is rotated to the switch position, the positioning column slides along the T-slot under the elastic force of the spring. The locking plate limits the positioning column, so that one end of the positioning column is precisely engaged with the positioning hole. This allows the handle to maintain a stable positioning state in complex environments, thereby preventing the crane from being accidentally demagnetized due to accidental touch of the handle by the operator. This solves the problem of lifting safety hazards caused by misoperation and improves the reliability and safety of lifting operations.

[0025] 2. In this utility model, pressing the pressing cap causes the pressing column and trapezoidal locking column to move downwards. The trapezoidal locking column pushes the locking ball to retract into the pin column, inserting the pin column into the crane body to complete the installation of the tile-shaped buffer pad. The spring returns to its original position, causing the locking ball to pop out and engage with the inner wall of the crane body, thereby making the tile-shaped buffer pad tightly fit the bottom of the crane, thus achieving the effect of buffering the rigid collision between the crane and the object. This solves the problem of the object being damaged by collision during the lifting process and improves the adaptability and protection of the equipment. Attached Figure Description

A tile-shaped buffer pad 4 is provided on the top of the lifting body 1 to absorb impact. The top of the tile-shaped buffer pad 4 fits against the bottom of the lifting body 1 to protect the lifted object. A connecting component is provided inside the tile-shaped buffer pad 4 to fix the position of the buffer pad. The reset component includes a spring 10, one end of which is fixedly connected to the side wall of the sliding disc 12 to provide elastic force. The other end of the spring 10 is fixedly connected to the inner wall of the hollow post 7 to maintain the stable engagement of the positioning post 9.

[0036] Reference Figure 1 - Figure 5The connecting components include a pin 13 and a ball catch 18. The pin 13 is fixedly connected inside the corrugated buffer pad 4 for quick installation of the buffer pad. The top of the pin 13 is slidably connected inside the crane body 1 to form a detachable connection structure. The ball catch 18 is slidably connected inside the pin 13 for automatic locking. The outer wall of the pin 13 engages with the inside of the crane body 1 to ensure connection stability. A fixed plate 14 is fixedly connected inside the pin 13 to provide an internal support structure. A pressing post 16 is slidably connected inside the fixed plate 14 to control the extension and retraction of the ball catch 18. A trapezoidal ball catch 19 is fixedly connected to the top of the pressing post 16 to push the ball catch 18 to move. A pressing cap 17 is fixedly connected to the top of the pressing column 16 for easy manual operation.

[0037] Working principle: During the lifting operation switch control process, rotating the handle 3 drives the fixed plate 6 to rotate synchronously. The fixed plate 6 drives the hollow column 7 to rotate together with the handle 3. When the handle 3 is rotated to the preset switch position, the positioning column 9 slides along the T-slot 8 inside the hollow column 7 under the elastic force of the spring 10. The locking plate 11 on the outer wall of the positioning column 9 slides synchronously along the T-slot 8 and limits the positioning column 9, so that one end of the positioning column 9 is accurately locked into the positioning hole 5 on the side wall of the crane body 1, realizing the stable positioning of the handle 3. When it is necessary to rotate the handle 3, the external force pushes the positioning column 9 to compress the spring 10, causing the locking plate 11 to slide in the opposite direction along the T-slot 8, and the positioning column 9 disengages from the fixed plate 6. Position hole 5 can be used to release the positioning. During the installation of the tile-shaped buffer pad 4, pressing the pressing cap 17 moves the pressing column 16 downward. The pressing column 16 moves the sliding plate 15 along the inner wall of the pin column 13 and compresses the spring 20. At the same time, the trapezoidal locking column 19 at the top of the pressing column 16 moves downward. The side wall of the trapezoidal locking column 19 pushes the locking ball 18 to retract into the pin column 13, inserting the top of the pin column 13 into the bottom of the crane body 1. After releasing the pressing cap 17, the spring 20 resets and pushes the sliding plate 15 and the pressing column 16 upward. The trapezoidal locking column 19 disengages from the locking ball 18, and the locking ball 18 pops out and engages with the inner wall of the crane body 1, completing the fixed installation of the tile-shaped buffer pad 4.
