Abstract
The invention discloses a breaker pushing device. A handcart driving screw rod, a handcart route positioning rod and a related interlock shaft operating piece of a pushing device are designed to be a center form; meanwhile, left and right sides of the device are additionally provided with symmetrically distributed guide rods. According to the invention, the traditional eccentric form of the pushing device is changed to the center form; therefore, the problem that one side of the breaker pushing device reaches the working position but the other side does not reach the working position due to the larger route bias caused by the horizontal imbalance appearing in the process of shaking a breaker to the working position by the eccentric pushing device is solved, so that the movement of the breaker is more steady and reliable.
Description
Technical field
The present invention relates to circuit breaker manufacturing technology field, especially a kind of propulsion plant that in the 40.5kV circuit breaker, uses.
Background technology
The propulsion plant of original 40.5kV circuit breaker has handcart to drive screw mandrel, handcart stroke backstay, interlocking shaft operating sheet, curved box etc., and handcart drives screw mandrel, handcart stroke backstay and relevant interlocking shaft operating sheet and is positioned at the position of taking back, propulsion plant center.Because shaking into being that interlock by handcart drives screw mandrel carries out of circuit breaker, when pressing the interlocking shaft operating sheet, inserting crank shakes circuit breaker in the process of service position, because propulsion plant is eccentric structure, left and right sides thrust is not of uniform size, cause circuit breaker progradation left and right sides stroke asynchronous, arrive the service position Yi Bian often exist, and another side does not reach the situation of service position yet.
Summary of the invention
The object of the present invention is to provide a kind of circuit breaker propulsion plant that can solve the asynchronous problem of the left right lateral journey of circuit breaker progradation.
To achieve these goals, technical scheme of the present invention is as follows: this circuit breaker propulsion plant comprises that handcart drives screw mandrel, handcart stroke backstay, interlocking shaft operating sheet, curved box, and described handcart drives the middle part that screw mandrel, described handcart stroke backstay and described interlocking shaft operating sheet are arranged at described curved box; Be fixed with guide post on the described curved box, described guide post arranges along the circuit breaker moving direction.
In the technique scheme, technical scheme can be more specifically: be provided with two guide posts on the described curved box, guide post is symmetrically arranged in handcart and drives the screw mandrel both sides.
Owing to adopted such scheme, the present invention and the traditional centering type device propulsion plant that opens circuit is compared and is had following beneficial effect:
1, the present invention drives the middle part that screw mandrel is arranged at curved box with handcart, makes circuit breaker shake thrust-balancing in the process of service position, arrives synchronously the service position about circuit breaker thereby make;
2, circuit breaker imports and exports along the guide post of center type propulsion plant, so that the circuit breaker turnover is more steadily reliable.
Description of drawings
Fig. 1 is the front view of circuit breaker propulsion plant.
Fig. 2 is the vertical view of circuit breaker propulsion plant.
Embodiment
The invention will be further described below in conjunction with concrete accompanying drawing:
Fig. 1, circuit breaker propulsion plant shown in Figure 2 include handcart and drive screw mandrel 1, handcart stroke backstay 2, interlocking shaft operating sheet 3, curved box 5, handcart drives the middle part that screw mandrel 1, handcart stroke backstay 2 and interlocking shaft operating sheet 3 are arranged at curved box 5, and handcart stroke backstay 2 is sheathed on handcart and drives outside the screw mandrel 1; Be fixed with guide post 4,6 on the curved box 5, guide post 4,6 is along the setting of circuit breaker moving direction and be symmetrically arranged in the both sides that handcart drives screw mandrel 1.
Claims (2)
1. circuit breaker propulsion plant, comprise that handcart drives screw mandrel, handcart stroke backstay, interlocking shaft operating sheet, curved box, is characterized in that: described handcart drives the middle part that screw mandrel, described handcart stroke backstay and described interlocking shaft operating sheet are arranged at described curved box; Be fixed with guide post on the described curved box, described guide post arranges along the circuit breaker moving direction.
2. a kind of circuit breaker propulsion plant according to claim 1 is characterized in that: be provided with two described guide posts on the described curved box, described guide post is symmetrically arranged in described handcart and drives the screw mandrel both sides.
