Description

Mute jacking device based on electromagnetic force Technical Field The invention relates to the field of equipment, in particular to a mute jacking device based on electromagnetic force. Background The overhead equipment is often used in automation equipment. Conventionally, an electromagnet, a cylinder, an electric push rod and the like are used as a jacking device and the like, which can generate about 70 dB of noise, and low noise is required in some branch fields (such as recuperation, buddha and the like). Disclosure of Invention The invention aims to overcome the defects of the prior art and provide a mute jacking device based on electromagnetic force. In order to solve the technical problems, the invention provides the following technical scheme. The invention relates to a mute jacking device based on electromagnetic force, which comprises a bottom plate (1), a first magnet (2), a direct current sucker type annular electromagnet (3), a second magnet (4), a push rod (5) and a guide pipe (6); the bottom plate (1) is provided with a through hole (11) and is fixed with a tooth hole (32) arranged on the direct current sucker type annular electromagnet (3) through a bolt; One end of the guide pipe (6) is empty, the other end of the guide pipe is arranged in a half-empty state with a hole (61), and the outer wall of the empty end of the guide pipe (6) is matched with the inner wall of the middle hole (31) of the direct current sucker type annular electromagnet (3) and fixed by glue beating; The second magnet (4) is provided with a through hole (41), is matched with one end of the ejector rod (5) and fixed by gluing, and is placed in the guide pipe (6), and the other end of the ejector rod (5) is exposed out of the end with the hole (61) of the guide pipe (6); The first magnet (2) is placed in the middle position of the middle hole (31) of the direct current sucker type annular electromagnet (3) and fixed on the bottom plate (1) by gluing, the first magnet (2) is at the lower end of the second magnet (4) and is in a repulsive state, and the fixed height of the first magnet (2) is higher than the upper plane of the direct current sucker type annular electromagnet (3) under the condition that the direct current sucker type annular electromagnet (3) is not electrified. Further, the first magnet (2) and the second magnet (4) are neodymium magnets. Further, the ejector rod (5) and the guide pipe (6) are made of nylon materials. The invention has the advantages that the principle of homopolar repulsion of the magnets is used for solving the problem of hard collision of the traditional electromagnet, the actual noise can be controlled below 40 dB and is far lower than the noise of 70 dB of the existing jacking device.
