Description

Disconnect switch electric lifting device

technical field

The utility model relates to a lifting tool for electric equipment, in particular to an electric lifting device for an isolating switch. the

Background technique

During the production process of the substation, it was found that there were many defects and potential safety hazards in the installation and disassembly of the 35kV disconnector, which seriously affected the stable operation of the equipment and the personal safety of maintenance personnel. Specifically, when installing and disassembling the 35kV isolating switch, due to insufficient safety distance from other live parts or unsuitable site environment, large cranes cannot be used, and manual handling and installation can only be relied on, which consumes too much manpower. Therefore need a kind of device that can lift this isolating switch conveniently. the

Contents of the invention

The utility model provides an electric lifting device for an isolating switch to solve the technical problem that the current 35kV isolating switch lacks a device that is convenient for lifting and saving manpower during the installation and dismounting process. the

The utility model is realized by adopting the following technical scheme: an electric hoisting device for an isolating switch, comprising a mobile platform, on which a base is fixed vertically, the upper part of the base rotates horizontally, and a base plate is fixed, and the base is fixed A vertical bar is fixed on the upper part of the bottom plate, a shaft pin is horizontally arranged on the top of the vertical bar, a U-shaped ring is vertically fixed on the front end of the shaft pin, and a hook device is hung on the lower part of the U-shaped ring; The power system and the wire rope on it; the wire rope is wound on the output end of the power system after bypassing the hook device; the power system is equipped with a control box and a button switch connected with the control box. the

The utility model has a compact structure and can move freely in the working area. When moving to the vicinity of the isolating switch that needs to be hoisted, use the hook device to hang the isolating switch, then start the power system through the control box, and lift the isolating switch through the movement of the wire rope. It can be lifted or lowered; the fixed bottom plate of the base is rotatably set on the base, which can rotate freely around the base in the working area, and the isolating switch can be rotated to different positions, which is convenient for lifting and placing the isolating switch, and does not need to be too large working space; the power system generally includes a motor and a reducer, and the control box is used to control the motor (start and rotation direction); specifically, it is controlled by a button switch; the hook device, power system, control box and button switch They are all technologies well known to those skilled in the art, and there are many ways to realize them, and there are also many models of corresponding devices to choose from. the

The 35kV isolating switch hoisting device described in the utility model saves human resources as much as possible and improves work efficiency under the premise of completely eliminating potential safety hazards in the installation process of the isolating switch. The overall structure is simple and small, flexible and convenient to move, and the production cost is also low. the

Detailed ways

An electric hoisting device for a disconnector, comprising a mobile platform 1, on which a base 2 is vertically fixed, the upper part of the base 2 rotates horizontally and is provided with a base fixed bottom plate, and a vertical bar is fixed on the upper part of the base fixed bottom plate 3. A shaft pin 4 is horizontally provided on the top of the vertical bar 3, and a U-shaped ring 5 is vertically fixed on the front end of the shaft pin 4, and a hook device 6 is hung on the lower part of the U-shaped ring 5; 3 on the power system 7 and the wire rope 8; the wire rope 8 is wound on the output end of the power system 7 after bypassing the hook device 6; the power system 7 is equipped with a control box 9 and a button switch 10 connected with the control box 9 . the

The base fixed bottom plate includes a lower bearing 11 fixedly connected to the base through an inner ring and a channel steel 12 horizontally connected to the outer ring of the lower bearing 11 . The top of the lower bearing 11 is fixed with a horizontal support fixedly connected with the outer ring of the bearing, and the vertical rod is fixed above the horizontal support and can rotate together with the lower bearing 11 . the

The top of the vertical bar 4 is connected with an upper bearing 13; the inner ring of the vertical bar 3 is fixedly connected with the upper bearing 13; the outer ring of the upper bearing 13 is fixedly connected with the shaft pin 4; the top of the upper bearing 13 is provided with The locking device 14 that upper bearing 13 matches.
