Background technology
Circuit breaker is 10kV vacuum circuit-breaker applied range in electric power system especially, and mechanism-trouble type is many, the replacing of the most common to be also most typical troubleshooting be exactly coil and energy storage motor, more when emat coil and energy storage motor, needs to remove the parts such as mechanism's energy-stored spring and just can carry out.As depicted in figs. 1 and 2, the structural design of major part circuit breaker is very compact, mechanism's energy-stored spring 1 installs location by the fixed head 2 at upper and lower two ends, and the space of mechanism's energy-stored spring 1 left and right sides is very narrow and small, owing to lacking special dismantling device, the dismounting of mechanism's energy-stored spring 1 is very difficult, efficiency is very low, causes repair quality greatly to reduce, and sometimes needs contact producer personnel to process, cause circuit breaker failure not eliminate in time, have a strong impact on electric power system and normally run and service quality.
Utility model content
The technical problems to be solved in the utility model overcomes the deficiencies in the prior art, provides the dismantling device for breaker mechanism energy-stored spring that a kind of structure is simple, easy to make, effectively can improve mechanism's energy-stored spring dismounting efficiency.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of dismantling device for breaker mechanism energy-stored spring, comprise connecting rod, the first clamping plate and the second clamping plate, described connecting rod two ends are provided with the contrary thread segment of rotation direction, described first clamping plate offer the first screwed hole and is installed on described connecting rod one end by the first screwed hole, described second clamping plate offer the second screwed hole and is installed on the described connecting rod other end by the second screwed hole.
Further improvement as technique scheme:
The spanner portion for driving described connecting rod to rotate also is provided with in the middle part of described connecting rod.
Described first clamping plate and the second clamping plate all offer the draw-in groove for the fixed head snap-fit engagement with mechanism energy-stored spring.
Described first clamping plate and the second clamping plate are equipped with the wedge guide being convenient to clamp the upper and lower two ends of described mechanism energy-stored spring.
Compared with prior art, the utility model has the advantage of: the dismantling device for breaker mechanism energy-stored spring of the present utility model, the parts comprised are few, and structure is simple, easy to make; During dismounting, first utilize the first clamping plate and the second upper and lower two ends of clamping plate gripping organ energy-stored spring, then swivel link, thread segment rotation direction due to connecting rod two ends makes two clamping plates mechanism's energy-stored spring can be compressed, clamp on the contrary, until mechanism's energy-stored spring contraction in length is to shifting out between upper and lower two pieces of fixed heads; Installation process is contrary with unloading process step, very convenient equally, quick, solves a difficult problem for mechanism's energy-stored spring dismounting inconvenience, substantially increases the dismounting efficiency of mechanism's energy-stored spring.
Further, connecting rod arranges spanner portion, by spanner rotary spanner portion thus drivening rod rotate, compare direct swivel link and decrease required power, use convenient.
Further, clamping plate arrange draw-in groove, clamping is coordinated with fixed head by draw-in groove, the first clamping plate and the second clamping plate can be prevented with link rotatable, its structure is simple, well make use of the tooth pad (fixed head) of mechanism's energy-stored spring 1 itself, make whole disassembly process convenient, reliable.
Further, the two ends that wedge guide is convenient to the first clamping plate and the second clamping plate fixture energy-stored spring are set, further increase the convenience of dismounting.

Embodiment
Below with reference to Figure of description and specific embodiment, the utility model is described in further details.
As shown in Figure 3 and Figure 4, the dismantling device for breaker mechanism energy-stored spring of the present embodiment, wherein mechanism's energy-stored spring 1 installs location by the fixed head 2 at upper and lower two ends, this dismantling device comprises connecting rod 3, first clamping plate 4 and the second clamping plate 6, connecting rod 3 two ends are provided with the contrary thread segment of rotation direction 31, first clamping plate 4 offer the first screwed hole 41 and be installed on connecting rod 3 one end by the first screwed hole 41, the second clamping plate 6 offer the second screwed hole 61 and be installed on connecting rod 3 other end by the second screwed hole 61.The dismantling device for breaker mechanism energy-stored spring of the present embodiment, the parts comprised are few, and structure is simple, easy to make; During disassembly mechanism energy-stored spring, first utilize the first clamping plate 4 and the second clamping plate 6 gripping organ energy-stored spring about 1 two ends, then swivel link 3, thread segment 31 rotation direction due to connecting rod 3 two ends makes the first clamping plate 4 and the second clamping plate 6 mechanism's energy-stored spring 1 can be compressed, clamp on the contrary, until mechanism's energy-stored spring 1 contraction in length is to shifting out between upper and lower two pieces of fixed heads 2; Installation process is contrary with unloading process step, very convenient equally, quick, solves a difficult problem for mechanism's energy-stored spring 1 dismounting inconvenience, substantially increases the dismounting efficiency of mechanism's energy-stored spring 1.
In the present embodiment, be also provided with in the middle part of connecting rod 3 for drivening rod 3 rotate spanner portion 5, by spanner rotary spanner portion 5 thus drivening rod 3 rotate, compare direct swivel link 3 and decrease required power, use convenient.
First clamping plate 4 and the second clamping plate 6 all offer the draw-in groove 7 for fixed head 2 snap-fit engagement with mechanism energy-stored spring 1.During use, by the fixed head 2 at draw-in groove 7 corresponding clamping mechanism energy-stored spring about 1 two ends on the first clamping plate 4 and the second clamping plate 6, clamping is coordinated with fixed head 2 by draw-in groove 7, can prevent the first clamping plate 4 and the second clamping plate 6 from rotating with connecting rod 3, namely when swivel link 3, first clamping plate 4 at its two ends can be done relative compression with the second clamping plate 6 and move, thus lead agency energy-stored spring 1 compresses, along with the first clamping plate 4 and the second clamping plate 6 move, mechanism's energy-stored spring 1 can be shifted out between upper and lower two pieces of fixed heads 2 after draw-in groove 7 exits fixed head 2.Its structure is simple, well make use of the tooth pad (fixed head 2) of mechanism's energy-stored spring 1 itself, makes whole disassembly process convenient, reliable.
In the present embodiment, the first clamping plate 4 and the second clamping plate 6 are equipped with the wedge guide 8 being convenient to fixture energy-stored spring about 1 two ends, are convenient to the two ends of the first clamping plate 4 and the second clamping plate 6 fixture energy-stored spring 1, further increase the convenience of dismounting.
