Abstract
The present invention relates to an operating mechanism for circuit breakers, particularly to an operating mechanism which has simple structure and can realize single-direction speed reduction and position control. The operating mechanism has the main technical scheme that a bracket is arranged on a main shaft, the bracket is hinged with a swing rod by a pin shaft, one end of the swing rod is hinged with a ratchet pawl, and the other end of the swing rod is hinged with a connecting rod; the main shaft is provided with a ratchet wheel, the ratchet pawl is matched with the ratchet wheel, the main shaft is provided with a position controlling plate, and the ratchet pawl is provided with a top plate. The position controlling plate can be in contact with the top plate in the process of rotating the ratchet wheel. The bracket is provided with an electric motor and a speed reducer which are connected with each other, and the other end of the connecting rod is hinged with an eccentric shaft in the speed reducer. The device has the advantage of simple structure, and enables the main shaft to run in the single direction and have accurate transmission position.
Description
Technical field
The present invention relates to a kind of operating mechanism of circuit breaker, specifically a kind of simple in structure, the operating mechanism that can realize unidirectional deceleration and Position Control.
Background technology
The existing circuit breaker operating mechanism as shown in Figure 2, motor 19 drives eccentric shafts 13 by decelerator 17 and rotates, thus drivening rod 14 is reciprocating.Suddenly and element 16 utilizes magnet steel 15 to make position probing, the connecting and disconnecting of back control motor 19 power supplys handled detection signal by controller 18.Its defective is an overall structure principle complexity, and controller is because the rotatory inertia of motor and can not the transmission position reliably being controlled causes circuit breaker often can't normally close a floodgate.
Summary of the invention
The objective of the invention is to design a kind of simple in structure, can make the unidirectional running of main shaft and have the electric operating mechanism of circuit-breaker of accurate transmission position.
Its main technical schemes: support is installed on the main shaft, utilizes the hinged fork of bearing pin on support, and an end and the ratchet of fork are hinged, and the other end and rod hinge connection are installed ratchet on main shaft, and ratchet cooperates with ratchet.Installation site control board on main shaft has top board on ratchet, position control plate can contact with top board in the rotation process of ratchet; Hinged locating detent on support, locating detent embed under spring action between ratchet on the ratchet.
Interconnective motor and decelerator are installed on support, and the other end and the eccentric shaft in the decelerator of connecting rod are hinged.
Advantage of the present invention is: when work, can utilize position control plate to back down ratchet, ratchet and ratchet are thrown off behind the operation certain angle again, make the position that main shaft is stopped to be needed, avoid the position of main shaft being changed, guarantee that circuit breaker works reliably because of the inertia of motor.Adopt the crank and rocker mechanism of forming by fork, ratchet and connecting rod in its deuterzooid device, made mechanism on the basis of not losing the output torque, significantly reduce used motor power (output), reduced energy consumption.In addition, the ratchet and pawl arrangement in this device has deceleration characteristic again, and the overall structure of motor-operating mechanism is become simply, has dwindled the volume of device, has improved mechanism's traveling comfort.
Description of drawings
Fig. 1 is a structure chart of the present invention.
Fig. 2 is original structure chart.
Embodiment
As shown in the figure: support 3 is installed on main shaft 11 and the crossbeam 2, utilizes bearing pin 20 hinged forks 6 on support 3, and an end and the ratchet 9 of fork 6 are hinged, and the other end and connecting rod 5 are hinged, and ratchet 12 is installed on main shaft 11, and ratchet 9 cooperates with ratchet 12.
Installation site control board 7 on main shaft 11 has top board 8 on ratchet 9, position control plate 7 can contact with top board 8 in the rotation process of ratchet 12.
Hinged locating detent 21 on support 3, locating detent 21 embed under spring action between ratchet on the ratchet 12.To avoid ratchet 7 to break away from the moment reversing of ratchet at ratchet.
During work, motor 1 drives eccentric shaft 10 by decelerator 4 and rotates, it is reciprocating that eccentric shaft 10 drives fork 6 by connecting rod 5, it is simultaneously reciprocating that the other end of fork 6 drives ratchet 9 again, promoting ratchet 12 by ratchet 9 rotates, ratchet 12 drives main shaft 11 again and makes circular motion, after turning to the angle of setting, the circuit breaker energy storage finishes, position control plate 7 just in time backs down top board 8, top board 8 drives ratchet 9 and breaks away from ratchet 12 simultaneously, ratchet 12 stops operating, because the disengagement of ratchet 12 and ratchet 9 has avoided motor to drive main shaft 11 rotations and the problem of damage circuit breaker and motor-operating mechanism under inertia, has prolonged the useful life of circuit breaker and motor-operating mechanism.
