Description

Technical Field

[0001] This utility model belongs to the technical field of hoisting equipment for supermagnetic equipment, and particularly relates to a hoisting device for supermagnetic equipment. Background Technology

[0002] Electromagnetic chucks generate magnetic force by energizing an internal coil. This force, passing through a magnetically conductive panel, firmly holds the workpiece in contact with the panel surface. De-energizing the coil removes the magnetism, facilitating the picking up and transporting of materials. The suction force is strong and can be adjusted by controlling the current, making it suitable for lifting heavy magnetic equipment of varying weights. However, it requires electricity to operate and thus demands a certain level of power stability. A sudden power outage during use could cause materials to fall, posing a safety risk.

[0003] Because the electromagnetic chuck attracts the target steel plate rapidly when it is energized, the collision between the electromagnet and the target steel plate generates a lot of noise, which causes the problem of relatively loud noise during the adsorption moment of conventional electromagnetic hoisting equipment.

[0004] To address this issue, we propose a hoisting device for supermagnetic equipment. Utility Model Content

[0005] The purpose of this invention is to solve the problem of high noise during the adsorption process of conventional electromagnetic hoisting equipment, and to propose a super magnetic equipment hoisting device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A hoisting device for supermagnetic equipment includes: a hanger, with an iron chain suspended from the side of the hanger, and a ring electromagnet suspended below the iron chain; a leather skirt is fixedly and sealed to the lower part of the ring electromagnet, and a valve shell is threaded and sealed onto the ring electromagnet; a valve plate is hinged to the outlet inside the valve shell; a compression spring is provided between the valve shell and the valve plate; one end of the compression spring is fixedly connected to the bottom surface of the valve plate, and the other end of the compression spring is fixedly connected to the inner wall of the valve shell; the compression force of the compression spring causes the valve plate to press against the outlet of the valve shell cavity to seal it. When the ring electromagnet is energized, the leather skirt surrounds the air inside, using air pressure to buffer the impact of the ring electromagnet on the target iron plate; at the same time, the leather skirt surrounds the impact point, reducing the sound intensity generated by the impact; and the leather skirt also hinders the transmission of sound waves, reducing noise.

[0007] Preferably, the annular electromagnet includes an electromagnet body, with a hanging ring fixedly connected to the upper end of the electromagnet body, and a threaded tube fixedly connected to the upper end of the electromagnet body. The lower part of the valve housing is threaded onto the threaded tube, and the chain hangs from the hanging ring. The threaded tube connects the valve housing, sealing it to the electromagnet body, allowing gas to be contained within the leather skirt and slowly discharged through the gap between the leather skirt and the target iron plate, thus facilitating impact cushioning.

[0008] Preferably, the valve housing includes a shell, the lower part of which is threaded onto the outer surface of a threaded tube. A hinge support component is fixedly connected to the inner wall side of the upper outlet of the shell. The valve plate is rotatably fixed to the hinge support component of the shell, and the valve plate seals against the upper opening of the shell. The valve plate obstructs the upward airflow, keeping the gas within the annular electromagnet, valve housing, and skirt. The spring force acts on the valve plate, keeping it closed. When force is applied to the valve plate, it overcomes the spring force and opens downwards, facilitating one-way exhaust from the valve housing.

[0009] Preferably, the valve housing further includes a hexagonal knob, which is fixedly installed at the lower part of the housing. By turning the hexagonal knob with a wrench, the housing can be rotated to unscrew it from the threaded tube, or to re-tighten it onto the threaded tube.

[0010] Preferably, the valve housing further includes a leather ring, which is fixedly connected to the lower end of the housing. After the housing is tightened, the leather ring seals the gap between the housing and the electromagnet body.

[0011] Preferably, the valve plate includes a valve plate body, with a leather piece fixedly connected to the upper end of the valve plate body. The upper end of the leather piece is sealed to the top surface of the housing. A rotating shaft is fixedly connected to one side of the valve plate body, and the rotating shaft is rotatably mounted on the inner wall side of the upper outlet of the housing. One end of a compression spring is fixedly connected to the bottom surface of the valve plate body, and the other end of the compression spring is fixedly connected to the inner wall of the upper outlet of the housing. The spring force acts on the rotating shaft, which in turn acts on the valve plate body, causing the valve plate body to act on the leather piece, thus facilitating the closure of the leather piece with the upper part of the housing.

[0012] Preferably, the valve plate is provided with a pin that extends out of the valve housing.

[0013] Preferably, the cavity of the valve housing has a convex shape so that the valve plate rests against the bottom of the cavity with a smaller diameter.

[0014] In summary, the technical effects and advantages of this utility model are as follows: 1. When the ring electromagnet is energized, the air is surrounded by a leather skirt, which uses air pressure to buffer the impact of the ring electromagnet on the target iron plate. At the same time, the leather skirt surrounds the impact point, reducing the sound intensity generated by the impact. The leather skirt also hinders the transmission of sound waves, reducing noise.

[0015] 2. The valve plate obstructs the upward airflow, keeping the gas within the annular electromagnet, valve body, and skirt. Additionally, the spring force acts on the valve plate to keep it closed. When the annular electromagnet is energized, the magnetic force pushes the skirt upward through the workpiece. The air pressure in the annular electromagnet slowly escapes through the gap between the skirt and the target iron plate, facilitating impact buffering. After the gas is released, the lower surface of the skirt makes tight contact with the workpiece, creating a seal and generating negative pressure inside the annular electromagnet.

[0016] 3. When force is applied to the valve plate, the valve plate overcomes the spring force and opens downwards, facilitating one-way exhaust from the valve body.

[0017] 4. The spring force acts on the valve plate, causing the valve plate body to act on the leather piece, which facilitates keeping the leather piece closed with the opening at the top of the housing. Attached Figure Description

[0020] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.

[0021] like Figure 1As shown, a hoisting device for supermagnetic equipment includes a hanger 1. A chain 7 is suspended from the side of the hanger 1, and a ring electromagnet 2 is suspended below the chain 7. A leather skirt 6 is fixedly and sealed to the lower part of the ring electromagnet 2. A valve housing 3 is threadedly and sealed onto the ring electromagnet. A valve plate 4 is hinged to the outlet (upper end) inside the valve housing 3. The valve plate 4 is movably disposed within the cavity of the valve housing 3 and can support the upper outlet of the cavity of the valve housing 3 for sealing. A compression spring 5 is provided between the valve housing 3 and the valve plate 4. One end of the compression spring 5 is fixedly connected to the bottom surface of the valve plate 4, and the other end is fixedly connected to the inner wall of the valve housing 3. The compression force of the compression spring 5 causes the valve plate 4 to support the outlet of the cavity of the valve housing 3 for sealing. When lowered, the power supply to the annular electromagnet 2 is disconnected. By acting on the valve shell 3, the valve shell 3 is opened against the elastic force of the spring 5, allowing gas to enter the leather skirt 6 through the annular electromagnet 2, neutralizing the negative pressure inside the leather skirt 6, and allowing the target iron plate to fall off smoothly.

[0022] like Figure 1 and 2 As shown, the annular electromagnet 2 includes an electromagnet body 21, with a hanging ring 23 fixedly connected to the upper end of the electromagnet body 21. A threaded tube 22 is also fixedly connected to the upper end of the electromagnet body 21. The lower part of the valve housing 3 is threaded onto the threaded tube 22, and the lower end of the valve housing 3 is sealed to the electromagnet body 21. An iron chain 7 is suspended from the hanging ring 23. By connecting the valve housing 3 to the threaded tube 22, the valve housing 3 is sealed to the electromagnet body 21, allowing the gas to be retained within the skirt 6 and slowly discharged through the gap between the skirt 6 and the target iron plate.

[0023] like Figure 1 and 3 As shown, the valve housing 3 includes a housing 31. The lower part of the housing 31 is threaded onto the outside of the threaded tube 22. A hinge support component is fixedly connected to the side of the housing 31. The hinge support component includes a rotating shaft and a hinge seat. The hinge seat is located on the inner wall side of the upper outlet of the housing. The rotating shaft is rotatably mounted on the hinge seat (not shown in the figure). The valve plate 4 is rotatably fixed to the hinge support component of the housing 31 (the valve plate rotates up and down around the hinge point). The valve plate 4 seals and presses against the upper opening of the housing 31. The valve plate 4 obstructs the upward airflow from the inside, keeping the gas within the annular electromagnet 2, the valve housing 3, and the skirt 6. The spring force of the compression spring acts on the valve plate 4, keeping the valve plate 4 in a closed state. When the spring force is applied to the valve plate 4, the valve plate 4 opens downward against the spring force, facilitating one-way exhaust from the valve housing 3.

[0024] like Figure 1 and 3As shown, the valve housing 3 also includes a hexagonal knob 33, which is fixedly installed on the lower part of the housing 31. By turning the hexagonal knob 33 with a wrench, the housing 31 can be rotated, allowing the housing 31 to be unscrewed from the threaded tube 22, or to be tightened back onto the threaded tube 22.

[0025] like Figure 1 and 3 As shown, the valve housing 3 also includes a leather ring 34, which is fixedly connected to the lower end of the housing 31. After the housing 31 is tightened, the leather ring 34 seals the gap between the housing 31 and the electromagnet body 21.

[0026] like Figure 1 and 4 As shown, the valve plate 4 includes a valve plate body 41. A leather piece 43 is fixedly connected to the top surface of the valve plate body 41. The upper end of the leather piece 43 is sealed to the upper opening of the housing 31. A rotating shaft 42 is fixedly connected to the root of the valve plate body 41. The rotating shaft 42 is rotatably mounted on the inner wall side of the upper outlet of the housing. One end of the compression spring 5 is fixedly connected to the bottom surface of the valve plate body 41, and the other end of the compression spring 5 is fixedly connected to the inner wall of the upper outlet of the housing 31. The elastic force of the compression spring 5 acts on the valve plate body 41, causing the valve plate body 41 to act on the leather piece 43, keeping the leather piece 43 closed to the upper part of the housing 31.

[0027] To facilitate pressure relief, a pin (not shown in the figure) is provided at the end of the valve plate 4 away from the rotating shaft, and the pin extends out of the valve housing 3. When lowered, the power supply to the annular electromagnet 2 is disconnected, and the pin acts on the valve plate 4, causing the valve plate 4 to open against the elastic force of the spring 5, allowing gas to enter the leather skirt 6 through the annular electromagnet 2, neutralizing the negative pressure inside the leather skirt 6, and allowing the target iron plate to fall off smoothly.

[0028] The cavity of the valve housing 3 has a convex shape so that the valve plate 4 abuts against the bottom of the cavity with a smaller diameter, that is, the valve plate 4 abuts against the upper cavity structure.

[0029] Working principle: When the ring electromagnet 2 is energized, the air is surrounded by the leather skirt 6, and the air pressure is used to buffer the impact of the ring electromagnet 2 on the target iron plate. At the same time, the leather skirt 6 surrounds the impact point, reducing the sound intensity generated by the impact. The leather skirt 6 also hinders the transmission of sound waves, reducing noise.

[0030] The above description is only a preferred embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed by the utility model, based on the technical solution and the utility model concept, should be included within the protection scope of the utility model.

[0031] The description briefly mentions the application direction of the utility model in relation to existing technologies known to those skilled in the art without modification, and combines them with the utility model to form a complete technology; it avoids excessive popularization of technologies known to those skilled in the art, in order to help those skilled in the art quickly understand the main content of the utility model.
