Abstract
The utility model relates to a portable 10kV vacuum circuit breaker energy -stored spring is parallel operation more, including first screw rod and second screw rod, first screw rod with the one end of second screw rod overlap respectively have with energy -stored spring first blade of both ends connecting piece assorted and second blade, first screw rod with the other one end of second screw rod couples together through the nut. The beneficial effects of the utility model are that: labour saving and time saving uses this instrument to significantly reduce the change time of vacuum circuit breaker's energy -stored spring in the maintenance, has reduced manpower over half simultaneously.
Description
Technical field
The utility model relates to power equipment maintaining field, specifically establishes and relates to a kind of portable 10kV vacuum circuit breaker energy-stored spring changer.
Background technology
Safeguard that the replacing of unit to the energy-stored spring of 10kV vacuum circuit breaker does not have specific purpose tool at present, but insert spring with the water pipe that the instrument such as screwdriver, iron prizes spring or use cutting by lever principle, make it to elongate, reduce the pressure that both sides fixed by spring, thus take out spring.Said method, takes time and effort, and due to spring tension comparatively large, easily crush people or be bound to equipment fragility position, cause accident.
Utility model content
In sum, for solving existing technical problem, the utility model provides a kind of portable 10kV vacuum circuit breaker energy-stored spring changer.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of portable 10kV vacuum circuit breaker energy-stored spring changer, comprise the first screw rod and the second screw rod, one end of described first screw rod and described second screw rod overlaps the first blade and the second blade that have and match with energy-stored spring two end connection respectively, and described first screw rod is connected by nut thread with other one end of described second screw rod.
Further, described first blade and described second blade rotating one end being enclosed within described first screw rod and described second screw rod respectively.
Further, described first blade and described second blade are the semi arch block being two circular arc block compositions.
The beneficial effects of the utility model are: the two ends of energy-stored spring are all provided with the connector be connected with transmission mechanism, are transmitted the energy of energy-stored spring by connector.The utility model is provided with the first blade and the second blade that match with energy-stored spring two end connection, by blade stretching energy-stored spring, completes the replacing of energy-stored spring, time saving and energy saving.Use this instrument to greatly reduce the replacing construction of the energy-stored spring of vacuum circuit breaker in maintenance, decrease manpower over half simultaneously.
Accompanying drawing explanation
Fig. 1 is the 3 D stereo schematic diagram of the utility model entirety;
Fig. 2 is assembling schematic diagram of the present utility model.
In accompanying drawing, the list of parts representated by each label is as follows:
1, the first screw rod, the 2, second screw rod, the 3, first blade, the 4, second blade, 5, nut, 6, circular arc block.
Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of portable 10kV vacuum circuit breaker energy-stored spring changer, comprise the first screw rod 1 and the second screw rod 2, one end of described first screw rod 1 and described second screw rod 2 overlaps the first blade 3 and the second blade 4 having and match with energy-stored spring two end connection respectively, preferred: state the semi arch block that described first blade 3 and described second blade 4 combine for being two circular arc blocks 6.Other one end of described first screw rod 1 and described second screw rod 2 is threaded by nut 5.
The two ends of energy-stored spring are all provided with the connector be connected with transmission mechanism, are transmitted the energy of energy-stored spring by connector.In maintenance process, when needing to change the energy-stored spring to 10kV vacuum circuit breaker, rotating nut 5 and keep the first screw rod 1 and the second screw rod 2 motionless, along with the rotation of nut 5, the end of the first screw rod 1 and the second screw rod 2 enters into can be more and more darker in nut 5, distance between first blade 3 and the second blade 4 also can be more and more nearer, until after the first blade 3 and the second blade 4 can withstand the connector at energy-stored spring two ends respectively, stop the rotation of nut 5.Again the first blade 3 and the second blade 4 are withstood connector respectively, due to one end being enclosed within the first screw rod 1 and the second screw rod 2 that the first blade 3 and the second blade 4 can horizontally rotate respectively, horizontally rotate the first blade 3 and the second blade 4 can make it be in the position of withstanding connector fast.After above-mentioned work completes, then reversely rotate nut 5 and same keep the first screw rod 1 and the second screw rod 2 motionless.Along with the rotation of nut 5, the first screw rod 1 and the second screw rod 2 can move respectively to nut 5 is outer, thus the distance between the first blade 3 and the second blade 4 also can be more and more far away.The first blade 3 and the second blade 4 gradually away from while, energy-stored spring is just elongated by the first blade 3 and the second blade 4, reduces the pressure on energy-stored spring both sides, thus takes out energy-stored spring, finally completes the replacing of energy-stored spring.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
