Abstract

The utility model discloses a simple and easy lifting device of 35kV circuit breaker, it comprises base and 7 font supports, the pedestal mounting is on the circuit breaker portal frame, 7 the bottom and the base of font support are connected and are realized 360 degrees rotations, 7 three fixed pulley is installed downwards at the top of font support, 7 the mid -mounting of font support has manual lift supporting rack, miniature electric block installs on manual lift supporting rack, miniature electric block's steel wire lifting rope walk around pass behind two fixed pulleys the couple again with another fixed pulley fixed connection. The utility model discloses the lifting device realizes through miniature electric block that electric lift improves the man -machine efficiency of operation greatly, and the scope that influences the electrified equipment that closes on moreover is little, and operation safety coefficient is high.

Description

35kV circuit breaker simple and easy hoisting instrument
Technical field
The utility model relates to a kind of tools manufacturing technology field, specifically a kind of simple and easy hoisting instrument for lifting 35kV arc-extinguishing chamber of circuit breaker porcelain bottle sleeve.
Background technology
All the time, the lifting of 35kV arc-extinguishing chamber of circuit breaker porcelain bottle sleeve is all use crane substantially, because the arm of crane is all long, it is larger that impact closes on charging equipment scope, and use crane when closing on charging zone and carrying out hanging device, the safety distance of crane and charging equipment can only use range estimation judging distance, and safety distance the personnel that not easily cause get an electric shock.Current measure of control have following 3: 1, increase monitoring staff; 2, expand power failure range to avoid closing on charging equipment; 3, at crane installing grounding jumper.Therefore, use the safety of operation coefficient of crane lifting 35kV circuit breaker not high.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple and easy hoisting instrument that the single-phase arc extinguish chamber porcelain bottle sleeve entirety of 35kV circuit breaker can be carried out lifting operation, and the scope that its impact closes on charging equipment is less, and safety of operation system is high.
The utility model solves the problems of the technologies described above with following technical scheme:
The utility model 35kV circuit breaker simple and easy hoisting instrument, it is propped up by base and 7 fonts and is configured to, floor installation is on circuit breaker portal frame, the bottom of 7 font supports is connected with base and realizes 360 degree and rotates, the top of 7 font supports is provided with three fixed pulleys downwards, the middle part of 7 font supports is provided with hand-operated lifting bearing support, minisize electric hoist is arranged on hand-operated lifting bearing support, is fixedly connected with after the wire sling of minisize electric hoist walks around two fixed pulleys through hook with another fixed pulley again.
The vertical rod member of described 7 font supports is divided at least two sections, and is bolted connection.
The utility model lifting device tool has the following advantages:
1, structure is simply easy to processing and manufacturing, connects combination installation convenient by screw.
2, on 7 font supports, minisize electric hoist is installed, realizes the man-machine efficacy that electric up-down improves operation greatly.
3, affect the scope of closing on charging equipment little, safety of operation system is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model lifting device.
In figure: 7 font supports 1, wire sling 2, hook 3, hand-operated lifting bearing support 4, base 5, bolt 6, fixed pulley 7, minisize electric hoist 8.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described:
The utility model 35kV circuit breaker simple and easy hoisting instrument is made up of base 5 and 7 font support 1, base 5 is arranged on circuit breaker portal frame by bolt, to realize 360 degree of rotary connections in two bearings of the bottom inserted base 5 of 7 font supports 1, also can be formed by alternate manner and be rotatably connected.The top cross bar of 7 font supports 1 is provided with three fixed pulleys 7 downwards, the middle part of 7 font supports 1 is provided with hand-operated lifting bearing support 4, minisize electric hoist 8 is arranged on hand-operated lifting bearing support 4, is fixedly connected with after the wire sling 2 of minisize electric hoist 8 walks around two fixed pulleys 7 of inner side through hook 3 with the fixed pulley 7 in outside again.
During installation, be first installed on 35kV circuit breaker portal frame by bolt by base 5, base 1 is provided with at least two bearings, in the bearing of the bottom inserted base 1 of 7 font supports 1, realizes being rotatably connected.Select the minisize electric hoist of suitable types to be arranged on hand-operated lifting bearing support 4 according to the pulling force of practical application, be fixedly connected with another fixed pulley again through hook 3 after the wire sling 2 of minisize electric hoist 8 being walked around two fixed pulleys 7 at top.
When 35kV arc-extinguishing chamber of circuit breaker porcelain bottle sleeve sling by needs, start minisize electric hoist 8, stop after making the contraction of wire sling 2 that hook 3 is moved to desired height, again single-phase arc extinguish chamber porcelain bottle sleeve entirety is hung on hook 3, restart minisize electric hoist 8, again single-phase arc extinguish chamber porcelain bottle sleeve entirety is moved to desired location by the contraction of wire sling 2, thus realize artificial lifting 35kV arc-extinguishing chamber of circuit breaker porcelain bottle sleeve like a cork, do not need to use crane operation, reduce operation power failure area, ensure the supply regular power of other equipment and reduced the risk of operation.
The vertical rod member of 7 font supports 1 can be divided into multistage by the utility model, needs longer vertical rod member, connects by bolted.
