Lifting support device for binding ring part of high-voltage-grade device body

Abstract

The invention relates to a lifting support device for binding a ring part of a high-voltage-grade device body, which comprises four supporting structures, rotating mechanisms and lifting mechanisms, and is characterized in that the supporting surface of each supporting structure is in planar contact with a current transformer body; each supporting structure is installed on an independent lifting mechanism, each supporting structure is provided with an independent rotating mechanism, and it is always guaranteed that the device body is supported by the planes of at least three supporting structures in the binding process; the four supporting structures are installed on an overall base through supports in an independent rotating mode, the overall base is provided with a fixed stand column, the supports are installed on the outer circle of the fixed stand column through four connecting plates respectively, and a horizontal supporting plate is installed above the supports. According to theinvention, the lifting mechanism is changed to ascend or descend, the handle is provided with a spring mechanism, the rotating direction is limited by a wedge-shaped positioning block, and the rotating force is buffered; the top of a lead screw is provided with a bearing for connecting the supporting plate, so that the rotating process does not influence the position of the device body.

Description

technical field [0001] The invention relates to an elevating support device, in particular to an elevating support device for wrapping the ring part of a high-voltage instrument body. Background technique [0002] At present, the body of high voltage (above 330kV), such as the body of inverted oil-immersed current transformer (welded structure of aluminum shell) in the transformer industry, has a total weight of more than 0.5 tons, and the lifting support is used when wrapping the ring of the body structure, the two circularly movable cylindrical support surfaces on the top are driven up or down by the lead screw. However, the use of this positioning tool has the following disadvantages: [0003] 1) Only when the disc-shaped handle continues to rotate can it drive the device body to rise or fall. For high-voltage products, the weight of the device body is relatively large, and the rotating force when rising is relatively large, which is difficult for a single person to comp...

Problems solved by technology

[0003] 1) Only when the disc-shaped handle continues to rotate can it drive the device body to rise or fall. For high-voltage products, the weight of the device body is relatively large, and the rotating force when rising is relatively large, which is difficult for a single person to complete

[0004] 2) The cylindrical support surface needs to be continuously rotated during the manual wrapping process, causing linear stress on the body and affecting the surface quality; at the same time, there are few stress points, which poses a safety hazard
