Description
Technical field
This utility model is related to belong to electric power overhaul field, and in particular a kind of 35kV breaker mechanisms energy-stored spring is new
Mounting or dismounting tools.
Background technology
At present, spring energy agency being equipped with known 35kV switching mechanisms more, by carrying out energy storage to spring in advance, pass through
Circuit control spring releases energy, and realizes the folding of chopper, but increasing with run time and action frequency, energy storage
Spring occurs different degrees of fatigue, and hydraulic performance decline affects the normal operation of chopper, field requirement to change energy-stored spring,
The spring contraction power is very big, it is difficult to pull open manually, due to no specific purpose tool, using common instrument, it is impossible to meet check man
The requirement of skill, while there is also certain potential safety hazard.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of 35kV breaker mechanisms energy-stored spring new dress
Tear instrument open, energy-stored spring quickly can be stretched by the instrument, facilitate the dismounting of energy-stored spring.
The present invention is achieved in that
A kind of new mounting or dismounting tools of 35kV breaker mechanisms energy-stored spring, the instrument include：
Installed in the leading screw with six square ends of described instrument one end；
The rear extension pawl near six square ends on the leading screw, for being combined with energy-stored spring；
Installed in the front hanging pawl of the other end of the leading screw, for being combined with energy-stored spring, coordinate the rear pawl of hanging store up
Can spring elongation；
It is near the rear stop nut for hanging pawl on leading screw, constant for position of the pawl on leading screw is hung after limiting.
Further, the leading screw is not provided with screw thread in the length of 4 centimetres of the root of six square ends to the present invention.
Further, the front hanging pawl is that, with female first metal tube, first metal tube is inserted in the present invention
On the leading screw, align with the bottom face of one first metallic plate, by the first metallic plate symmetrical longitudinal measure in first metal
Guan Shang, first metallic plate are rearwardly turned down along extension, form claw-like.
Further, the female thread of first metal tube is consistent with the screw thread of leading screw for the present invention.
Further, the rear pawl of hanging includes the second metal tube to the present invention, and second metal tube is inserted on the leading screw,
Align with one second metallic plate bottom, symmetrical longitudinal measure, the second metallic plate are rearwardly turned down along extension, form claw-like.
Further, the second metal bore is slightly larger than leading screw external diameter to the present invention.
Compared with prior art, beneficial effect is this utility model：This utility model hangs pawl before and after coordinating using leading screw
Use, hang the appropriate location that pawl is hung in energy-stored spring in front and back, by rotating threaded shaft, energy-stored spring is stretched, be easy to scene
Dismounting and change, improves replacing speed.Solve energy-stored spring replacing and do not meet maintenance craft, the problem for wasting time and energy.
Reasonable in design, simple structure is easy to operation, convenient fine setting stretching distance, long service life improve work effect
Rate, improves technological level.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, with reference to embodiments, to this
Invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, not
For limiting this utility model.
Referring to the new mounting or dismounting tools of a kind of 35kV breaker mechanisms energy-stored spring that Fig. 1, this utility model embodiment are provided,
Including：Leading screw 4, front hanging pawl 5 hang pawl 2 and stop nut 3 afterwards.
It is leading screw 4 of the one end with six square ends 1 by leading screw 4.The diameter with diameter greater than leading screw 4 of six square ends 1,
And leading screw 4 is near no screw thread in the length of 4 centimetres of the root of six square ends 1.
Front hanging pawl 5 is arranged on leading screw, for being combined with energy-stored spring.
Front hanging pawl 5 is alignd with 51 bottom of the first metallic plate of Qian type with female first metal tube 52, symmetrical longitudinal direction
It is welded on the first metal tube, by the leading screw that the first metal tube is inserted in, it is noted that front hanging pawl does not have installed in leading screw
One section of six square ends, the first metallic plate of Qian type are rearwardly turned down along the extension 53 of the first metallic plate, form claw-like,
The female thread of metal tube is consistent with the screw thread of leading screw.
Hang pawl 2 afterwards to install near six square ends 1 of leading screw, for being combined with energy-stored spring.
The shape for hanging pawl 2 afterwards is consistent with front hanging pawl, including the second metal tube 22 and 21 bottom pair of the second metallic plate of Qian type
Together, symmetrical longitudinal measure, the second metallic plate 21 of Qian type are rearwardly turned down along the extension 23 of the second metallic plate 21, form pawl
Shape, metal bore are slightly larger than leading screw external diameter.
Arrange a stop nut to be arranged on leading screw, it is constant for position of the pawl on leading screw is hung after limiting.
Front hanging pawl, stop nut and rear extension pawl are installed on leading screw, are hung pawl afterwards and are limited by stop nut, can fix
Arbitrarily rotate at position, and be not subjected to displacement, front hanging pawl can be subjected to displacement with the rotation of leading screw.
This utility model stop nut 3 is hung pawl 2 after guaranteeing and is not had on threaded position in leading screw 4 and can rotate, and does not send out
Raw displacement, rotational lead screw 4, front hanging pawl 5 can produce displacement on leading screw 4, and the blade tooth for hanging pawl 2 and front hanging pawl 5 afterwards is opposite, uses
When hang the appropriate location that pawl 2 and front hanging pawl 5 are hung in spring by rear, rotational lead screw 4 hangs pawl 2 one end of spring is solid afterwards
Fixed, front hanging pawl 5 drives spring elongation, can smoothly realize the dismounting of spring.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention, all essences in the present invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
