Description
Technical field
This utility model relates to a kind of instrument for prying open energy-stored spring.
Background technology
As it is shown in figure 1, vacuum circuit breaker operating mechanism includes roller 1, apical axis 2, energy storage maintenance pallet 3, energy storage maintenance axle 4 and combined floodgate bent plate 5.The substantially work process of this vacuum circuit breaker operating mechanism is as follows: during energy storage, and motor output shaft drives roller 1 to rotate clockwise (looking from right to left), stretches energy-stored spring 6 by connecting lever and carries out energy storage；When arriving energy storage position, energy storage keeps axle 4 to disengage with sprocket drive system, and energy storage maintenance pallet 3 withstands roller 1 and is maintained at energy storage position；During combined floodgate, making electromagnet clashing into combined floodgate bent plate 5 and be flipped up, drive energy storage to keep axle 4 to rotate, make energy storage keep pallet 3 to unclamp roller 1, energy-stored spring 6 shrinks and closes a floodgate.As shown in Figure 1, the placement space of energy-stored spring 6 is narrow and small, owing to not having special instrument that it is installed, causes that the installation in trouble of energy-stored spring 6 is required great effort.
Utility model content
For the above-mentioned technical problem existed in prior art, the utility model proposes a kind of instrument for prying open energy-stored spring, it adopts the following technical scheme that
A kind of instrument for prying open energy-stored spring, including fairlead, lead, hydraulic cylinder, base, the first support arm and the second support arm；Lead is installed in fairlead and is slidably connected with described fairlead；Hydraulic cylinder is made up of hydraulic cylinder body and hydraulic cylinder piston rod, and wherein, the bottom of hydraulic cylinder body and the bottom of fairlead are arranged on base, and the top of hydraulic cylinder piston rod is connected with the top of lead；First support arm is connected horizontally on the upper end sidepiece of lead, and the second support arm is connected horizontally on the lower end sidepiece of fairlead, and the first support arm and the second support arm are arranged in parallel up and down.
Preferably, the first support arm has a pointed insertion end, and the second support arm has a pointed insertion end.
This utility model has the advantage that
This utility model is provided with fairlead, lead, hydraulic cylinder, base, the first support arm and the second support arm, wherein, lead is installed in fairlead and is slidably connected with described fairlead, the cylinder body base of hydraulic cylinder and the bottom of fairlead are arranged on base, the top of hydraulic cylinder piston rod is connected with the top of lead, and the upper end sidepiece level connection joint at lead has the first support arm, lower end sidepiece level connection joint at lead has the second support arm, and the first support arm and the second support arm are arranged in parallel up and down.By above-mentioned design, make when using this tamper tool energy-stored spring, first the first support arm and the second support arm can be inserted two positions up and down of energy-stored spring, then hydraulic cylinder action is controlled, hydraulic cylinder piston rod extends and drives lead to move upward, and drives the first support arm to move upward simultaneously, owing between the first support arm and the second support arm, spacing increases, it is easy to pry open energy-stored spring, thus realizing the installation of energy-stored spring.This utility model simple in construction, easy to operate.

Wherein, 1-roller, 2-apical axis, 3-energy storage keeps pallet, and 4-energy storage keeps axle, 5-combined floodgate bent plate；6-energy-stored spring；7-fairlead, 8-lead, 9-base, 10-the first support arm, 11-the second support arm, 12-cylinder body, 13-piston rod.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, this utility model is described in further detail:
Shown in Fig. 2, a kind of instrument for prying open energy-stored spring, including fairlead 7, lead 8, hydraulic cylinder, base the 9, first support arm 10 and the second support arm 11.
Wherein, lead 8 is installed in fairlead 7 and is slidably connected with fairlead 7.
Hydraulic cylinder is made up of hydraulic cylinder body 12 and hydraulic cylinder piston rod 13, and wherein, the bottom of the bottom of hydraulic cylinder body 12 and fairlead 7 is arranged on base 9, and the top of hydraulic cylinder piston rod 13 is connected with the top of lead 8.
First support arm 10 is connected horizontally on the upper end sidepiece of lead 8, and the second support arm 11 is connected horizontally on the lower end sidepiece of fairlead 7, and the first support arm 10 and the second support arm about 11 are arranged in parallel.
By the first support arm 10 and the second support arm 11 are carried out appropriate design, it is simple to when prying open energy-stored spring, it is possible to two support arms are inserted in the small space for placing energy-stored spring simultaneously.
First support arm 10 and the second support arm 11 are shaft-like design.
Additionally, the first support arm 10 and the second support arm 11 are separately fixed on the lead 8 and fairlead 7 that are slidably matched, to ensure that the first support arm 10 is relative to the directivity of the second support arm 11 action and stability.
For the ease of inserting in energy-stored spring by the first support arm 10 and the second support arm 11, the first support arm 10 is inserted end and is designed as pointed by this utility model, is designed as pointed by the insertion end of the second support arm 11 simultaneously.
This utility model is not by the impact of energy-stored spring placement space, easy to operate.
Certainly; described above it is only preferred embodiment of the present utility model; this utility model is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the instruction of this specification; made all equivalent replacement, obvious variant, all fall within the essential scope of this specification, ought to be subject to protection of the present utility model.
