Description
Technical field
The present invention relates to power circuit breaker technical field, and in particular to a kind of power circuit breaker spring dismounting device and its make
Use method.
Background technology
Application of the switch of spring-type operating mechanism type in field of power in recent years is more and more universal, this kind of to open
Complex structure is closed, part changes difficulty greatly, wherein difficult with the dismounting of spring.Cause mechanism case due to compact to design
The useless force extension spring of narrow space, dismounting spring wastes time and energy or even cannot dismantle, and conventional maintainer dismantles spring
Method is that a number of pad is filled in spring, and spring is propped up certain length, can be pulled down spring, but this method can be led
Spring medial and lateral discontinuity is caused, is not slightly noticed during dismounting spring that pad is easily ejected and is hurted sb.'s feelings, safety coefficient is low, and this
Method is more time-consuming, and the bomb disposal spring time is also longer than changing damage part time.
Applying date 2014.03.23, the patent document of application number 201420130695.0 disclose a kind of novel energy-storing spring
Dismounting aid, including two pieces of seesaws, a swingle and a support bar, the front end of seesaw is provided with flat cutting edge and U-shaped
Opening, to facilitate gap during insertion spring unstored energy, the rear end of seesaw is provided with the silk cap into a single integrated structure with seesaw, swingle
Top silk to the silk of upper seesaw silk cap to identical, swingle bottom silk to lower seesaw silk cap silk to identical, and top with
Bottom silk is to conversely, medium position formation fulcrum type connection of the support bar to upper and lower two pieces of seesaws, support bar two ends are provided with regulation
Nut, can adjust support pole length to adapt to the spring of different length, but instrument yet suffers from problem：By described
It is when swingle adjusts the spacing of upper and lower seesaw, when producing angle of inclination between the swingle and the upper and lower seesaw, described
Produce between swingle and upper and lower seesaw silk cap and interfere so as to continue to adjust, between the support bar and upper and lower seesaw
Interference can be produced so as to continue to adjust, the range of accommodation of the device is very limited.
