Description
Technical field
The utility model relates to a kind of electric power system substation equipment maintenance and repair instrument, particularly relates to a kind of 10kV breaker mechanism spring assembling/disassembling tool, for 10kV overhaul of line breaker, failture evacuation, belongs to T & D Technology field.
Background technology
To there is quantity in 10kV circuit breaker more in electric power system, 10kV circuit breaker is overhauled or troubleshooting process in, often need its in-house spring of dismounting, original dismounting spring method used is very loaded down with trivial details, namely utilize manpower by spring distending the instruments such as screwdriver with many, and remain on energy storage state and spring could be pulled down, the method time is longer, efficiency is low, so need longer interruption duration; And due to the elastic potential energy of mechanism's inner spring very large, if control with great difficulty not damage substation equipment maintenance and repair professional, potential risk is high.
Utility model content
The utility model is for above-mentioned problems of the prior art, provide a kind of 10kV breaker mechanism spring assembling/disassembling tool, solve 10kV circuit breaker in electric power system carry out overhauling and troubleshooting time efficiency low, there is the problem of potential safety hazard, shorten interruption duration.
The technical solution of the utility model is as follows.
Connector center is threaded cover, and one end of threaded rod is fixedly linked through thread bush and base; The two ends of connector are connected with spring fork respectively by pivot pin, two spring fork free actions on the axis of connector; Connecting plate is fixed between base and spring fork by pivot pin.
External screw thread and the connector thread bush internal thread of described threaded rod match.
Described threaded rod other end termination is provided with rotation jack.
Described base and connector square crossing.
The two ends of described base are provided with fixed head.
One end of described connecting plate is fixed on base fixing plate, and the connecting plate other end is fixed on spring fork sidewall.
Described spring fork is symmetricly set on the two ends of connector.
The utility model tool has the following advantages:
Utilize cooperation and the connection of swivel nut and screw rod, compare with the method for original dismounting 10kV breaker mechanism inner spring, can find out the way being forced spring distending by Mechanical course than manpower plug rigidity object, fail safe has obvious lifting, has saved the time simultaneously.Therefore the utility model effectively improve 10kV circuit breaker overhauled and troubleshooting time operating efficiency, evaded the risk that substation equipment maintenance and repair professional is damaged.And this instrument carries out simply processing and can completing to original paper, structure is simple, with low cost, can Reusability.

Fig. 3 is side structure schematic diagram of the present utility model.
In figure, 1, spring fork, 2, threaded rod, 3, connector, 4, base, 5, connecting plate, 6, pivot pin, 7, jack.
Embodiment
Referring to accompanying drawing, in conjunction with specific embodiments, concrete structure of the present utility model is described in detail.
Embodiment
As Figure 1-3, connector 3 center is threaded cover, base 4 is arranged on below and the connector square crossing of connector, the two ends of base are provided with fixed head, one end of threaded rod 2 is fixedly linked through thread bush and base center, threaded rod other end termination is provided with rotates jack 7, and external screw thread and the connector thread bush internal thread of threaded rod match; The two ends of connector 3 are connected with spring fork 1 respectively by pivot pin 6, and two spring forks are symmetricly set on the two ends of connector, two spring fork free actions on the axis of connector; Connecting plate 5 is fixed between base and spring fork by pivot pin, and one end of described connecting plate 5 is fixed on base fixing plate by pivot pin, and connecting plate 5 other end is fixed on spring fork sidewall by pivot pin.
The utility model utilizes the cooperation of threaded rod and thread bush to achieve 2 objects, and one is have firmly effectively gradually by the function of 10kV breaker mechanism inner spring distending; Secondly after spring is by distending, its energy storage state of maintenance that can be good.
During use, spring fork 1 is pitched the two ends into 10kV breaker mechanism inner spring, then rotate threaded rod 2, threaded rod 2 is moved to base 4 direction by the cooperation of the thread bush at connector 3 center.Because of relative fixing with the position of threaded rod 2 end in base 4, so the gap between base 4 and connector 3 is becoming large gradually, and the length of connecting plate 5 is fixing, by the distance under the effect of each portion pivot pin 6 between two spring clips in increase, spring distending gradually can be made thus, and can make spring stable remain on energy storage state, distending put in place can be safe and reliable when meeting knocked down condition remain on this state, spring can conveniently be pulled down by substation equipment maintenance and repair professional.Otherwise, form contrary during installation therewith.
