Technical Field
[0001] This utility model belongs to the technical field of electro-permanent magnet suction cup lifting tools, specifically relating to an electro-permanent magnet suction cup lifting tool. Background Technology
[0002] Electro-permanent magnet chucks, also commonly known as permanent magnet lifters or permanent magnet chucks, are lifting tools that utilize the strong attraction of permanent magnet materials to lift magnetic materials. A permanent magnet chuck mainly consists of two parts: a permanent magnet chuck and a unloading device. The permanent magnet chuck contains a permanent magnet and a magnetic guide block. Through a unique magnetic circuit design, the magnetic lines of force generated by the permanent magnet pass through the magnetic guide block, attracting the magnetic material and forming a closed loop, thus achieving the purpose of lifting the magnetic material. When in use, permanent magnet chucks are generally connected to a crane to lift items. However, connecting the existing crane's connecting buckle to the permanent magnet chuck is cumbersome. Because the lifting ring of the electro-permanent magnet chuck cannot be quickly opened and closed, tools are needed to disassemble the lifting ring and connect it to the permanent magnet chuck, making it difficult to easily fit the crane's connecting buckle inside the lifting ring of the electro-permanent magnet chuck. Therefore, we propose an electro-permanent magnet chuck lifting device. Utility Model Content
[0003] The purpose of this utility model is to provide an electro-permanent magnet suction cup lifting device to solve the problem mentioned in the background art that the lifting ring of the electro-permanent magnet suction cup lifting device is not convenient enough when connecting to the crane connecting buckle.

[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. 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.
[0020] Please see Figures 1 to 5 This utility model provides a technical solution: an electro-permanent magnet suction cup lifting device, including a permanent magnet suction cup 1, a lifting ring 2 fixed to the top of the permanent magnet suction cup 1, a closable opening mechanism provided on one side of the lifting ring 2, and a protective mechanism provided at the bottom of the permanent magnet suction cup 1. The closable opening mechanism includes: a closable opening component, provided on one side of the lifting ring 2; a reset component, provided at the top between the closable opening component and the lifting ring 2; and a locking component, provided at the bottom between the closable opening component and the lifting ring 2.
[0021] In this embodiment, preferably, the closable opening assembly includes an opening groove 100 formed on one side of the lifting ring 2 and a closing post 101 disposed inside the opening groove 100, and the surface of the closing post 101 is provided with anti-slip particles 102.
[0022] In this embodiment, preferably, the reset component includes an internal groove 200 formed at the top of the closed post 101. The internal groove 200 is slidably connected to the top of the open groove 100. The internal groove 200 is provided with a telescopic spring 201 connected to the top of the open groove 100, which facilitates the sliding reset of the closed post 101.
[0023] In this embodiment, preferably, the surface of the lifting ring 2 is symmetrically provided with a guide groove 300 and guide blocks 301 symmetrically fixed on both sides of the inner wall of the built-in groove 200 relative to the top of the opening groove 100. The guide blocks 301 are engaged with the guide groove 300 so that the closing column 101 plays a guiding role when sliding.
[0024] In this embodiment, preferably, the locking assembly includes a mating groove 400 formed at the bottom of the opening groove 100 and a mating block 401 fixed at the bottom of the closing post 101. The mating block 401 is engaged with the mating groove 400 to allow the closing post 101 to be connected to the bottom of the opening groove 100.
[0025] In this embodiment, preferably, a locking hole 500 and a screw hole 501 that penetrates one side of the inner wall of the docking groove 400 are provided on one side of the docking block 401. A locking screw 502 that penetrates the inside of the screw hole 501 and connects to the locking hole 500 is provided on one side of the lifting ring 2. By screwing the locking screw 502 into the locking hole 500, the docking block 401 can be firmly fixed inside the docking groove 400.
[0026] In this embodiment, preferably, the protective mechanism includes a protective cover 600 sleeved on the bottom of the permanent magnet suction cup 1 and buckles 601 symmetrically fixed on both sides of the inner wall of the protective cover 600. By engaging the protective cover 600 with the bottom of the permanent magnet suction cup 1, the bottom of the permanent magnet suction cup 1 can be protected.
[0027] The working principle and usage process of this utility model are as follows: When connecting the crane's connecting buckle to the lifting ring 2 at the top of the permanent magnet suction cup 1, first loosen the locking screw 502 on the side of the lifting ring 2, so that its end exits from the inside of the locking hole 500 and screws into the inside of the screw hole 501, releasing the positioning of the docking block 401. Then, the anti-slip particles 102 push the closing column 101 upward, causing the built-in groove 200 to slide upward at the top of the opening groove 100, compressing the telescopic spring 201 and causing it to deform. This also causes the guide block 301 to slide inside the guide groove 300, providing a guiding function. At the same time, the docking block 401 is pulled out from inside the docking groove 400, thus opening the opening groove 100. Then, the crane's connecting buckle is fitted into the inside of the lifting ring 2 through the opening groove 100, and then released. Pulling the closing column 101 causes the built-in groove 200 to slide downwards on the surface of the lifting ring 2 under the action of the telescopic spring 201, causing the docking block 401 to be inserted into the docking groove 400 to close the opening groove 100. Then, tightening the locking screw 502 causes it to rotate inside the screw hole 501 and engage with the locking hole 500 to fix the connection, thus locking and positioning the docking block 401 and the docking groove 400, completing the connection of the lifting device. When the permanent magnet suction cup 1 needs to be placed on the ground, in order to protect the bottom of the permanent magnet suction cup 1, the protective cover 600 is placed on the bottom of the permanent magnet suction cup 1 while the permanent magnet suction cup 1 is still being lifted, and the buckle 601 acts as a limit, so that the protective cover 600 protects the bottom of the permanent magnet suction cup 1.
[0028] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
