Abstract
The invention discloses an operation mechanism with three-position switch. The operation mechanism with three-position switch comprises a fixed front plate and a fixed back plate. A primary switch operation shaft and an earthing switch operation shaft are arranged between the front plate and the back plate. An interlock plate is arranged on the primary switch operation shaft, and an earthing interlock plate is arranged on the earthing switch operation shaft. An energy storage spring is fixed on one side of the interlock plate and the earthing interlock plate through a pin roll. A dead plate is fixed on another side of the interlock plate and the earthing interlock plate through the primary switch operation shaft and the earthing switch operation shaft. A slot hole is arranged on the dead plate and the length and direction of the slot hole is same with the dead plate. An interlock roller is arranged in the slot hole through the pin roll which is placed between the interlock plate and the earthing interlock plate and the interlock roller is used for the movement of the interlock plate and the earthing interlock plate. The diameter of the interlock roller is greater than the space between the interlock plate and the earthing interlock plate. Compared to the prior art, the problem that the long radius interlock plate must be replaced during the capacity increase of the existing operation mechanism with three-position is solved.
Description
Technical field
The present invention relates to power equipment manufacturing technology field, particularly a kind of switch operation mechanism.
Background technology
In existing three-station operating mechanism, have a kind of such as Chinese utility model patent (time of disclosure 2008.02.13, the patent No.: 200720139710.8) disclosed operation machine for three work position load switch, this operation machine for three work position load switch include fixing rear plate, fixed front plate, the main shaft that extends to switch-box, on-load switch operating axis, ground connection operating axis, interlock plate etc.The interlocking of described operation machine for three work position load switch is to drive when rotated the interlock plate that is contained on itself by operating axis, carry out the direct interlocking between interlock plate and the interlock plate, although this mode is simple and practical, but the power output that is only applicable to operating mechanism is little, the operating mechanism that distance between two operating axis is less, when the operating mechanism output shaft requires power output larger, just must change spring, strengthen distance and the interlock plate of changing large radius between two operating axis, the radius of interlock plate is crossed conference and is brought processing difficulties, the excessive problems such as contact overshoot that cause easily of the operating difficulties that causes owing to quality is excessive and inertia.
Summary of the invention
The object of the present invention is to provide a kind of three-station operating mechanism, it can effectively solve the excessive problem of interlock plate radius.
In order to address the above problem, the technical scheme of this three-station operating mechanism is: this three-station operating mechanism, include fixing front and rear panels, between described front and rear panels, be provided with main switch operating axis and earthed switch operating axis, be provided with an interlock plate at described main switch operating axis, be provided with a ground connection interlock plate at described earthed switch operating axis, be fixed with an energy-stored spring in a side of described interlock plate and described ground connection interlock plate by bearing pin.Opposite side at described interlock plate and described ground connection interlock plate is fixed with a fixed head by described main switch operating axis and described earthed switch operating axis, be provided with a slotted hole consistent with its length direction at described fixed head, be coated with an interlocking roller that is used for the activity of the top described interlock plate of card and described ground connection interlock plate by bearing pin in described slotted hole, the diameter of described interlocking roller is greater than the spacing between described interlock plate and the described ground connection interlock plate.
Because adopt technique scheme, the present invention compared with prior art has following beneficial effect:
1. the interlocking roller of the present invention by setting up between two interlock plates, this directly interlocks and is indirectly interlocking, has increased the versatility of interlock board.
2. the present invention is simple in structure, and is easy to use.

Embodiment
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1, Fig. 2 and this three-station operating mechanism shown in Figure 3, include header board 1 and the rear plate 3 fixed by support column 2, be provided with output shaft 4, main switch operating axis 5 and earthed switch operating axis 6 between header board 1 and the rear plate 3, main switch operating axis 5 and earthed switch operating axis 6 are respectively by connecting rod 9 and ground connection connecting rod 10 driver output axles 4, be provided with an interlock plate 16 at main switch operating axis 5, be provided with a ground connection interlock plate 12 at earthed switch operating axis 6, be fixed with an energy-stored spring 7 in a side of interlock plate 16 and ground connection interlock plate 12 by bearing pin.Opposite side at interlock plate 16 and ground connection interlock plate 12 is fixed with a fixed head 13 by main switch operating axis 5 and earthed switch operating axis 6, be provided with a slotted hole consistent with its length direction at fixed head 13, be coated with an interlocking roller 14 that is used for the activity of top card interlock plate 16 and ground connection interlock plate 12 by bearing pin 15 in slotted hole, the diameter of interlocking roller 14 is greater than the spacing between interlock plate 6 and the ground connection interlock plate 12.Its specific works is as follows:
When clockwise operation main switch operating axis 5, make main switch realize closing a floodgate by connecting lever 8 drivening rods 9 driver output axles 4, interlock plate 16 promotion activity to the right interlocking roller 14 is pressed on the ground connection interlock plate 12 of earthed switch operating axis 6, stuck earthed switch operating axis 6, it can not be clockwise rotated, when reaching the main switch combined floodgate, the purpose that earthed switch can not close a floodgate realizes mechanical interlocking; In like manner, operate counterclockwise main switch operating axis 5, make the switch separating brake by connecting lever 8 drivening rods 9 driver output axles 4, interlock plate 16 leaves movable interlocking roller 14, at this moment rotate counterclockwise earthed switch operating axis 6, drive ground connection connecting rod 10 driver output axles 4 by earthed crank arm 11 and be grounded combined floodgate, ground connection interlock plate 12 promotion activity left interlocking roller 14 is pressed on the interlock plate 16 of main switch operating axis 5, stuck main switch operating axis 5, it can not be clockwise rotated, when reaching the earthed switch combined floodgate, the purpose that main switch can not close a floodgate realizes mechanical interlocking.
