Automatic permanent magnet lifter

Abstract

The invention discloses an automatic permanent magnet lifter. According to the automatic permanent magnet lifter, a sliding lifting ring is lifted so that two sector fans can be matched to rotate a third gear so as to rotate a movable magnet, and therefore a suction magnetic field can be formed for adsorbing an object and lift the object. The automatic permanent magnet lifter is characterized in that a bottom sucker is arranged at the bottom of a lifter shell; two lifting rings are symmetrically arranged on the top of the lifter shell; elastic blocks are arranged on the inner side face of thetop end of the lifter shell; the elastic blocks correspond to the lifting frame and are rubber blocks; the number of the elastic blocks is preferably two; a rotating shaft is arranged in the lifter shell, and the two ends of the rotating shaft are arranged at the two ends of the lifter shell through bearings correspondingly; the movable magnet is fixedly arranged on the rotating shaft in a sleeving manner; a fixed magnet is arranged over the movable magnet and is horizontally placed; two fixing seats are fixedly arranged at the two ends of the fixed magnet correspondingly; the tops of the fixing seats are connected with the upper inner side face of the lifter shell; and the lifting frame is arranged in the lifter shell and is located above the fixed magnet.

Description

technical field [0001] The invention relates to an automatic permanent magnet lifter, which relates to a lifter for adsorbing and hoisting a magnetically conductive object when an object is transported, and belongs to the field of mechanical equipment. In particular, it relates to an automatic permanent magnet lifter that pulls the sliding ring to make the two sector gears cooperate to rotate the third gear to rotate the moving magnet, thereby forming a suction magnetic field to attract objects for lifting. Background technique [0002] The permanent magnet lifter, also known as the permanent magnet suction lifter, has the characteristics of small size, strong holding force, no electricity, almost zero residual magnetism, and high safety factor. Most of the permanent magnet lifters currently used are manual control type. Start the switch, the personnel rotate the remote lever on the jack to drive the internal moving magnet to rotate, and cooperate with the fixed magnet to fo...

Problems solved by technology

[0002] The permanent magnet lifter, also known as the permanent magnet lifter, has the characteristics of small size, strong holding force, no electricity, almost zero residual magnetism, and high safety factor. Most of the permanent magnet lifters currently used are manual. Start the switch, and the personnel rotate the remote lever on the jack to drive the internal moving magnet to rotate, and cooperate with the fixed magnet to form an attractive magnetic field, but the handle of this hand-operated permanent magnet jack is easy to cause a shock The accidental closing of the heavy equipment caused the occurrence of lifting accidents. Although the limit column was used to fix the position of the remote rod, it needs to be controlled by personnel every time when it is used. The lifting operation method is inconvenient and affects the efficiency of lifting work.

[0003] The notification number CN206427906U discloses a safe permanent magnet crane, including a crane outer shell, a lifting hook is arranged above the crane outer shell, and a crane hook fixing plate is provided at the connection position between the crane outer shell and the lifting hook, A moving magnet rotating shaft is arranged at the inner middle position of the outer casing of the crane, and a lifting suction cup is arranged below the outer casing of the crane, and a fixed magnet N pole is arranged at one end above the inner upper end of the moving magnet rotating shaft, and a fixed magnet is arranged at the other end. The S pole of the magnet, the rotating handle of the crane lacks the structure to fix the handle, and the handle is easy to be bumped and rotated during lifting, causing the permanent magnetic lifting magnetic closure to disappear, resulting in a greater safety hazard

[0004] Notification number CN206427907U discloses a kind of hand rod retractable permanent magnet lifter specially used for lifting, including a jack housing, a hand rod limit bolt and a ring fixing mounting frame, and one side of the jack housing is provided with A movable magnet connection head, a telescopic rod installation sleeve is arranged above the movable magnet connection head, the hand lever limit bolt is installed on the telescopic rod installation sleeve, and a magnet is embedded above the telescopic rod installation sleeve Rotate the threaded hand lever, the side of the lifter shell close to the movable magnet connector is provided with a hand lever limit hole, and the inside of the lifter shell is provided with a rotating permanent magnet below the inside of the lifter shell, the inside of the lifter shell A fixed permanent magnet is arranged near the top of the rotating permanent magnet, and permanent magnet fixing buckles are arranged in the inside of the jack housing near the two ends of the fixed permanent magnet. The lever is accidentally closed due to collision. When operating the limit, the personnel need to unscrew the limit bolt. At the same time, when using the hand lever, the limit bolt needs to be disassembled again. The operation is inconvenient and time-consuming
