Embodiment
Breaker handcart advancing mechanism of the present utility model, its preferable embodiment be, comprises the fixed frame that is provided with guide rail, the travelling frame of load-bearing breaker, and described travelling frame is arranged on the guide rail of described fixed frame;
Described travelling frame is provided with screw-nut body, and described fixed frame is provided with the forward operation axle, is provided with arrangement of clutch between the leading screw of described forward operation axle and described screw-nut body.
Described travelling frame is provided with on the guide rail of described fixed frame by roller.
The nut of described screw-nut body is fixed on the described travelling frame, axial location between described forward operation axle and the described fixed frame;
The front end of described forward operation axle and the rear end of described leading screw are by clutch sleeve engagement or disconnection.
Described travelling frame is connected with the release plate, and an end of described release plate is corresponding with the position of described clutch cover;
When described travelling frame drive circuit breaker was advanced into service position or test position, described release plate just can promote described clutch sleeve motion, makes engagement of described forward operation axle and leading screw or disengagement.
Handcart high-voltage switch cabinet of the present utility model, its preferable embodiment are that this handcart high-voltage switch cabinet is provided with above-mentioned breaker handcart advancing mechanism.
Specific embodiment is as shown in Figure 1 and Figure 2:
Propulsive mechanism is made up of a fixed frame that guide rail 19 is housed 2, a travelling frame 4 (load-bearing breaker on it) and several major parts of feed screw nut screw mechanism that roller 1 is housed.
Clutch-pedal support 11 is fixedlyed connected with fixed frame 2 by guide rod 5, and leading screw 16 is by axial location between location-plate 12 and the fixed frame 2.Operating axis 8 is by axial location between location-plate 9 and the fixed frame.Rotating operation axle 8 drives leading screw 16 rotations by clutch sleeve 7, and nut 15 is fixed on the travelling frame 4, and the rotation of leading screw 16 can make travelling frame 4 move forward or backward, realizes that circuit breaker is by test position moving to the service position.
The clutch function implementation is:
Advancing and withdrawing from the process, (release plate 17 is enclosed within on the guide rod 5 clutch sleeve 7 remaining on the centre position under the effect of four stage clips 6 by being stuck in the interior release plate 17 of its fluting, can endwisely slip along guide rod 5), be fixed in operating axis 8 and fixedly in the kidney slot of 10 of straight pins and the clutch sleeve 7 of leading screw 16, operating axis 8 and fixedly leading screw 16 rotate synchronously, when approaching work of travelling frame or test position, the baffle plate 14 promotion dropout plates 17 and the clutch sleeve 7 that are fixed on the travelling frame 4 move forward or backward, straight pin 10 is deviate from the cylinder groove of clutch sleeve 7, leading screw 16 and operating axis 8 rotate no longer synchronously, can realize clutch function.
The effect of spacer pin 3 is the accurate positions when guaranteeing that travelling frame is advanced into the service position or withdraws to test position.
In the utility model, propulsive mechanism is a monolithic construction, the travelling frame that relies on a load-bearing breaker moving forward and backward on a fixed frame that guide rail is housed realize circuit breaker by test position to moving between the service position, the support that only needs the carrying fixed frame on the switch cubicle, and do not need guide rail, the moving of circuit breaker only in the propulsive mechanism body, carry out and and do not have relative motion relation between the switch cubicle, make forward operation flexibility and reliability and displacement size very accurate.Propulsion mode adopts screw-nut body, and axially on fixed frame, nut is fixed on the travelling frame screw mechanism, and circuit breaker can move forward and backward during rotational lead screw.This mechanism is provided with arrangement of clutch, when circuit breaker moves to test position or service position, clutch is thrown off automatically, even operating personnel are rotated further the leading screw handcart and also can move, feel to judge whether circuit breaker moves into place thereby avoid operating personnel to rely on, the accurate positioning of simple to operate and circuit breaker.
The above; it only is the preferable embodiment of the utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection range of the present utility model.
