Description
Technical field
The utility model relates to a kind of maintenance of equipment instrument, relates in particular to a kind of scissor vacuum circuit breaker spring assembling/disassembling tool.
Background technology
Vacuum circuit breaker because of its have volume little, lightweight, be applicable to the advantages such as frequent operation, arc extinguishing need not overhaul, in power distribution network, use comparatively universally, the main use used as the control and protection high voltage electric equipment in switch cubicle, middle-placed switch cabinet etc. usually.In actual motion, the time have the situations such as breaker energy storage motor, divide-shut brake coil burnout to occur, because its locations of structures restriction when it is carried out service work, needs just can carry out after the energy-stored spring dismounting dismounting with vacuum circuit breaker energy-stored spring operating mechanism first.And because energy-stored spring has larger prestretching active force, the pretension that dismounting and assembling must overcome energy-stored spring stretches energy-stored spring, on not having special use during tool, install, dismantle the energy-stored spring difficult, motionless with pulling, argue also because being difficult to find fulcrum to exert oneself, increase difficulty, prolong the service work time to service work.
The patent disclosure of the patent No. 200920206991.3 a kind of spring assembling/disassembling tool, although can stretch to energy-stored spring, but it uses comparatively trouble, especially need to insert simultaneously two opening forks of this spring assembling/disassembling tool in the spring, very inconvenient, make troubles, prolong the service work time to service work.
The utility model content
For the prior art above shortcomings, the purpose of this utility model just is to provide a kind of scissor vacuum circuit breaker spring assembling/disassembling tool, and is easy to use, can fast energy-stored spring be pushed up and stretch, and reduces the difficulty of energy-stored spring dismounting, increases work efficiency.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of scissor vacuum circuit breaker spring assembling/disassembling tool, it is characterized in that: comprise handle, drive link, gripper shoe, clamp frame and clamp holder, described gripper shoe middle part has a screw, the middle part of drive link has the screw thread that cooperates with described screw, and gripper shoe and drive link link together by threaded engagement; The upper end of described drive link is fixedly connected with the handle middle part, and its lower end and clamp frame are flexibly connected, and by turning handle clamp frame are moved up or down; Described clamp holder is at least two, and be symmetricly set in the both sides of gripper shoe, be symmetrically arranged with the through hole that clamp holder is passed on the clamp frame, the upper end of clamp holder is rotationally connected by rotating shaft and gripper shoe after described through hole passes, and symmetrically arranged two clamp holder bottoms are drawn close mutually; The relative two side portions of the bottom of described clamp holder is blade-like.
This spring assembling/disassembling tool principle is similar to the scissors principle, its clamp holder substructure is close with the scissor blade structure, when utilizing this instrument dismounting energy-stored spring, this energy-stored spring dismantling device is clamped energy-stored spring on the vacuum circuit breaker spring operating mechanism, then rotary handle, clamp frame is moved down, thereby make the clamp holder move toward one another of this dismantling device, until the blade-like of clamp holder bottom is partially submerged in the gap of spring, make energy-stored spring be subject to thrust to two ends, overcoming the pretension of energy-stored spring, thereby the energy-stored spring top is stretched, at this moment, the connecting pin of spring one end just is easy to take off or install owing to stressed disappearance (or stressed reducing).This specific purpose tool does not need to fill special fixed support and lever, operates faster convenience.
Further, the bottom of described clamp holder bends inwards first, again bending downwards; The center line of the two through hole that two symmetrical clamp holders pass is positioned at the orthographic projection outside of two shaft axis on clamp frame.By such design, make clamp frame move down very short distance and just can well energy-stored spring be pushed up and stretch.
Further, described clamp holder is symmetrically arranged 4.The ingenious four-jaw type fixed support mode of having used, more stable, and do not need to fill special fixed support and lever, operate faster convenience.
Compared with prior art, the utility model has the advantage of: simple in structure, easy to use, can fast energy-stored spring be pushed up and stretch, reduce the difficulty of energy-stored spring dismounting, increase work efficiency.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment: referring to Fig. 1 to Fig. 4, a kind of scissor vacuum circuit breaker spring assembling/disassembling tool comprises handle 1, drive link 2, gripper shoe 3, clamp frame 4 and clamp holder 5.Described gripper shoe 3 middle parts have a screw, and the middle part of drive link 2 has the screw thread that cooperates with described screw, and gripper shoe 3 and drive link 2 link together by threaded engagement; The upper end of described drive link 2 is fixedly connected with handle 1 middle part, and its lower end and clamp frame 4 are flexibly connected, and by turning handle 1 clamp frame 4 are moved up or down.Described clamp holder 5 is at least two, and is symmetricly set in the both sides of gripper shoe 3, is symmetrically arranged with the through hole that clamp holder 5 is passed on the clamp frame 4, and the upper end of clamp holder 5 is rotationally connected by rotating shaft and gripper shoe 3 after described through hole passes; Symmetrically arranged two clamp holder bottoms are drawn close mutually.The bottom of described clamp holder 5 reduces gradually near the cross section of inside part, makes the relative both sides of two clamp holders, 5 bottoms be blade-like.Specifically adding man-hour, the bottom of described clamp holder 5 bends inwards first, again bending downwards, and the center line of the two through hole that two symmetrical clamp holders 5 pass is positioned at the orthographic projection outside of two shaft axis on clamp frame.By such design, make clamp frame 4 move down very short distance and just can well energy-stored spring be pushed up and stretch, more laborsaving, and better effects if.
When utilizing this instrument dismounting energy-stored spring, this energy-stored spring dismantling device is clamped energy-stored spring on the vacuum circuit breaker spring operating mechanism, then rotary handle, clamp frame is moved down, thereby make the clamp holder move toward one another of this dismantling device, until the blade-like of clamp holder bottom is partially submerged in the gap of spring, make energy-stored spring be subject to thrust to two ends, to overcome the pretension of energy-stored spring, thereby the energy-stored spring top is stretched, at this moment, the connecting pin of spring one end just is easy to take off or install owing to stressed disappearance (or stressed reducing).This specific purpose tool does not need to fill special fixed support and lever, operates faster convenience.
As a kind of embodiment, described clamp holder is symmetrically arranged 4; The ingenious four-jaw type fixed support mode of having used, more stable, and do not need to fill special fixed support and lever, operate faster convenience.
Need to prove at last, above embodiment is only in order to the technical solution of the utility model to be described but not the restriction technologies scheme, although the applicant has been described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are made amendment to the technical solution of the utility model or are equal to replacement, and do not break away from aim and the scope of the technical program, all should be encompassed in the middle of the claim scope of the present utility model.
