Description

Technical Field

[0001] This utility model relates to the field of electromagnetic lifting technology, specifically to an electro-permanent magnet adsorption device for mobile lifting equipment. Background Technology

[0002] Mobile lifting equipment is a type of lifting machinery with mobile capabilities, mainly used in industries, ports, construction and other fields. When lifting and handling some metal goods, in order to facilitate hoisting and improve the efficiency of lifting and handling, electro-permanent magnets are used to attract and fix the metal goods.

[0003] Existing mobile lifting equipment using electro-permanent magnet adsorption devices has several drawbacks. After the electro-permanent magnet adsorption device is fixed to the goods, it is difficult to adjust the position of the adsorption device on the goods, which makes it difficult to adjust the center of gravity of the goods after hoisting. This reduces the efficiency of stable adsorption and hoisting. Furthermore, the contact surface of the metal goods is not cleaned during the electro-permanent magnet adsorption process, which makes it easy for foreign objects and dust to accumulate between the electro-permanent magnet adsorption device and the surface of the metal goods, thus reducing the stability of the adsorption and fixation. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned above, such as the difficulty in adjusting the position of the adsorption device on the goods after adsorption and fixation, which makes it difficult to adjust the center of gravity of the goods after hoisting, thus reducing the efficiency of stable adsorption and hoisting, and the difficulty in cleaning the contact surface of the metal goods, which makes it easy for foreign objects and dust to exist between the electro-permanent magnet adsorption device and the surface of the metal goods, thus reducing the stability of adsorption and fixation. This utility model provides an electro-permanent magnet adsorption device for mobile lifting equipment.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: An electro-permanent magnet adsorption device for mobile lifting equipment includes a body and an adsorption frame. The adsorption frame is fixedly installed at the bottom of the body. A main winding group is evenly installed inside the bottom of the adsorption frame. Auxiliary winding groups are symmetrically installed on the left and right sides of the main winding group inside the bottom of the adsorption frame. Connecting pipes are symmetrically opened inside the left and right sides of the adsorption frame. Telescopic columns are symmetrically limited and slidably connected to the front and rear sides of the left and right sides of the adsorption frame. Ball bearings are limited and rolled at the bottom of the telescopic columns. A spring is fixedly connected between the top of the telescopic columns and the inner wall of the adsorption frame.

[0006] Furthermore, the front and rear sides of the connecting pipes on the left and right sides are bent vertically downwards, and the downward openings on the front and rear sides of the connecting pipes are connected to the limiting sliding connection of the telescopic column, so that air can enter the interior of the sliding connection of the telescopic column through the connecting pipes.

[0007] Furthermore, an air inlet is provided at the center of the top of the telescopic column, and an exhaust groove is provided on the side of the telescopic column facing the center of the adsorption frame. The exhaust groove is connected to the bottom of the air inlet, so that the air entering the sliding connection of the telescopic column can enter the air inlet and then be discharged outward through the exhaust groove.

[0008] Furthermore, the top of the air inlet is provided with a flared opening to allow air to enter the air inlet better, and the exhaust channel is tilted downwards so that the air discharged from the exhaust channel can better sweep away the dust on the surface of the goods below the adsorption frame.

[0009] Furthermore, plugs are symmetrically fixedly installed on the left and right sides of the adsorption frame. The plugs are used to connect to the air compressor through the pipe, and the inside of the plug is connected to the connecting pipe, so that high-pressure air can enter the connecting pipe through the plug.

[0010] Furthermore, handles are symmetrically fixedly installed on the left and right sides of the top of the machine body, and a fixed base is fixedly installed in the center of the top of the machine body. A lifting ring is fitted on the top of the fixed base to achieve hoisting after adsorption and fixation. An indicator light is installed on the left side of the fixed base at the top of the machine body to facilitate observation of the working status and usage position.

[0011] Furthermore, a power switch panel is installed on the left end face of the machine body, and a control panel is installed on the right end face of the machine body, so as to realize the power supply and operation control of the electro-permanent magnet adsorption device.

[0012] The beneficial effects of this utility model are as follows: This invention, through the design of the telescopic column and ball bearings at the bottom of the adsorption frame, combined with the function of the auxiliary winding assembly, enables the adsorption frame to first adhere to the surface of the metal goods during adsorption and fixation. The position is then adjusted by the ball bearings, facilitating the adjustment of the center of gravity during hoisting and improving the efficiency of stable adsorption and hoisting. Furthermore, the design of the air inlet and exhaust slot inside the telescopic column, combined with the connection between the pipeline and the air compressor, allows the surface of the metal goods below the adsorption frame to be blown away during the movement of the adsorption frame, thereby preventing foreign objects and dust from remaining between the adsorption frame and the surface of the metal goods and improving the stability of adsorption and fixation.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0016] An electro-permanent magnet adsorption device for mobile lifting equipment according to a preferred embodiment of the present invention will be described in detail below, such as Figures 1-8 As shown, an electro-permanent magnet adsorption device for mobile lifting equipment includes a body 1 and an adsorption frame 2. The adsorption frame 2 is fixedly installed at the bottom of the body 1. A main winding group 3 is evenly installed inside the bottom of the adsorption frame 2. Auxiliary winding groups 4 are symmetrically installed on the left and right sides of the main winding group 3 inside the bottom of the adsorption frame 2. Connecting pipes 5 are symmetrically opened inside the left and right sides of the adsorption frame 2. The front and rear sides of the connecting pipes 5 are bent vertically downwards, and the downward openings on the front and rear sides of the connecting pipes 5 are connected to the limiting sliding connection of the telescopic column 6, so that air can enter the interior of the sliding connection of the telescopic column 6 through the connecting pipes 5.

[0017] The adsorption frame 2 has symmetrical sliding connections of telescopic columns 6 on the front and back sides of the left and right sides. An air inlet 61 is provided at the center of the top of the telescopic column 6. An exhaust groove 62 is provided on the side of the telescopic column 6 facing the center of the adsorption frame 2. The exhaust groove 62 is connected to the bottom of the air inlet 61, so that the air inside the sliding connection of the telescopic column 6 can enter the air inlet 61 and then be discharged outward through the exhaust groove 62.

[0018] The top of the air inlet 61 is provided with a flared opening, which allows air to enter the air inlet 61 better. The exhaust channel 62 is tilted downwards, which allows the air discharged from the exhaust channel 62 to better sweep away the dust on the surface of the goods below the adsorption frame 2.

[0019] Plugs 9 are symmetrically fixed on the left and right sides of the adsorption frame 2. Plugs 9 are used to connect to the air compressor through the pipe, and the inside of plugs 9 is connected to the connecting pipe 5, so that high-pressure air can enter the connecting pipe 5 through plugs 9.

[0020] The bottom of the telescopic column 6 is connected to a ball bearing 7, and the top of the telescopic column 6 is fixedly connected to the inner wall of the adsorption frame 2 with a spring 8.

[0021] Handles 10 are symmetrically fixed on the left and right sides of the top of the machine body 1. A fixed base 11 is fixedly installed in the center of the top of the machine body 1. A lifting ring 12 is fitted on the top of the fixed base 11 to achieve the hanging after adsorption and fixation. An indicator light 13 is installed on the left side of the fixed base 11 at the top of the machine body 1 to facilitate the observation of the working status and usage position.

[0022] A power switch panel 14 is installed on the left end face of the body 1, and a control panel 15 is installed on the right end face of the body 1, so as to realize the power supply and operation control of the electro-permanent magnet adsorption device.

[0023] The working principle of this utility model is as follows: In use, the body 1 and suction frame 2 are placed on the surface of the metal goods by using the handle 10. Then, the body 1 and suction frame 2 are connected to the lifting equipment by the design of the fixing seat 11 and the lifting ring 12. Then, the plug 9 is used to connect to the air compressor through the pipe, so that high-pressure air can be delivered to the connecting pipe 5.

[0024] During adsorption and fixation, the auxiliary winding groups 4 on the left and right sides of the bottom of the adsorption frame 2 are activated first, so that the adsorption frame 2 can attract each other to the surface of the metal goods. However, the force of mutual attraction is small at this time. The telescopic column 6 will be exposed downward under the action of the spring 8, so that the bottom end face of the adsorption frame 2 does not contact the surface of the metal goods. With the action of the ball bearing 7 at the bottom of the telescopic column 6, the machine body 1 and the adsorption frame 2 can be adsorbed on the surface of the metal goods, and can also be moved more easily to adjust the position. This makes it easier to adjust the center of gravity of the hoisting and improves the efficiency of stable adsorption hoisting.

[0025] As the machine body 1 and the adsorption frame 2 move on the surface of the metal goods, the high-pressure air that enters the connecting pipe 5 through the air compressor can enter the air inlet 61 in the center of the telescopic column 6 through the connecting pipe 5, and then be blown out obliquely downward from the exhaust groove 62, thereby sweeping the surface of the metal goods below the adsorption frame 2.

[0026] After the center of gravity of the hoisting is adjusted, the main winding group 3 at the bottom of the adsorption frame 2 is activated, which generates a greater attractive force, causing the compression spring 8 of the telescopic column 6 to retract inward into the interior of the adsorption frame 2, so that the bottom end face of the adsorption frame 2 contacts the surface of the metal goods, thereby completing the adsorption and fixation of the adsorption frame 2 and the metal goods, and cooperating with the connected lifting equipment to lift and transfer the metal goods.

[0027] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
