Description
Technical field
A kind of instrument for changing spring is the utility model is related to, a kind of breaker open operation spring is related in particular to and more changes the outfit
Put.
Background technology
The existing replacing options of type breaker open operation spring of LW16~40.5 have manpower cable traction method and big spanner chock block
Pulling method.Manpower cable traction method clasps spring one end with rope, and by 2~3 people while tow is with extension spring, spring top
End enters after mounting hole with tight nut.Manpower cable traction method Renewal process is cumbersome, expends time length, needing 3~4 people to coordinate can
Complete, security is poor, and debugging difficulty is big, and spring easily occurs and jams a finger, and is slipped there is also rope powered near hurting sb.'s feelings and being thrown to
The potential safety hazard at interval.Big spanner chock block pulling method spanner and wooden unit will be padded on mechanism side face angle greatly, and personnel are to pulling greatly
Hand exerts a force with extension spring.Because the tripping spring position of the type breaker of LW16~40.5 can use position of the fulcrum space small,
Using the stretchable limited length of big spanner chock block pulling method, it is unfavorable for follow-up debugging efforts, and this method was changed
Journey is also relatively complicated, and equally needing 3~4 people to coordinate can be completed, and spanner is heavier to be not convenient to use, and wooden unit be present and big spanner falls
Fall to injure by a crashing object the security risk of personnel and equipment, security is poor.Two kinds of replacing options change and the debugging spring average used time >=
45 minutes, change and debugging efficiency is low, the risk that delay power transmission be present.Therefore, existing replacing instrument can not ensure operating personnel
Personal safety and the quickness and high efficiency of Renewal process.
The content of the invention
For above-mentioned prior art, the technical problems to be solved in the utility model is that providing a kind of new spring changes work
Tool, breaker open operation spring can be easily changed, improve operating efficiency, and can guarantee that operating personnel's personal safety, that is, met
High efficiency and security.
In order to solve the above technical problems, the utility model provides a kind of breaker open operation spring more changing device, including branch
Spring elongation part is flexibly connected, made by support part part, rotatable parts and spring elongation part, the rotatable parts with support member
Spring elongation part can using rotatable parts as fulcrum the rotation with surface where support member；
The support member includes support bar and fixed seat, and described support bar one end is fixedly connected with fixed seat, the other end
Rotatable parts are installed；The fixed seat is that at least round-meshed " Contraband " type structure is opened in side, and be furnished with what is matched with circular hole size
Bolt；
Cross through hole is provided with the middle part of the rotatable parts, is connected between its both ends and support bar by latch；
The spring elongation part includes U-shaped card slot and handle, and the width of the U-shaped card slot is matched with spring, can clamped
Spring is relatively non-slip；The handle passes through the through hole on rotatable parts.
The use of breaker open operation spring more changing device, by replacing construction from it is original >=be reduced within 45 minutes 14 minutes,
Replacing efficiency is greatly improved, while new tool is without assembling, it is safe and efficient, use manpower and material resources sparingly, optimize allocation of resources.
As improvement of the present utility model, the U-shaped card slot is provided with screw thread.
As further improvement of the utility model, the U-shaped card slot and handle are combined by welding.
Further improved as of the present utility model, the pin diameter is Φ 12mm.
In summary, using above-mentioned breaker open operation spring more changing device, breaker open operation spring can be easily changed,
Operating efficiency is improved, and can guarantee that operating personnel's personal safety, that is, meets high efficiency and security.

Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings：
As shown in Figure 1 to Figure 3, breaker open operation spring more changing device of the present utility model includes support member 1, rotation section
Spring elongation part 3 is flexibly connected by part 2 and spring elongation part 3, the rotatable parts 2 with support member 1, makes spring elongation
Part 3 can be fulcrum with rotatable parts 2 in the place rotation with surface of support member 1；
The support member 1 includes support bar 11 and fixed seat 12, and described one end of support bar 11 is fixed with fixed seat 12 to be connected
Connect, other end installation rotatable parts 2；The fixed seat 12 is " Contraband " type structure that at least side is provided with circular hole 13, and equipped with
The bolt 14 of the size of circular hole 13 matching；
