Abstract
The utility model relates to a vacuum circuit breaker, in particular to an anti-reverse mechanism of a vacuum circuit breaker handle operating device. The technical scheme is that the anti-reverse mechanism of the vacuum circuit breaker handle operating device comprises a connector arranged between a handle and a transmission shaft, one end of the connector is connected with the handle in a clamping way, the other end of the connector is sheathed with the transmission shaft, ratchets are evenly distributed on the internal periphery of the connector connected with the transmission shaft and at least a group of limiting pieces is arranged between the transmission shaft and the internal periphery of the connector. By adopting the technical scheme, the utility model has the advantage of stable operation.
Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker, the anti-inversion organization of the lever operated device of particularly a kind of vacuum circuit-breaker.
Background technology
At present, the operating mechanism that is used to control inner separating brake of vacuum circuit-breaker and combined floodgate on market and the data is typically provided with two groups, is respectively electronic control section and manual control part.Electronic control section is by motor and the linkage interlock that constitutes the vacuum circuit-breaker divide-shut brake, and manual control part then links by the linkage of handle and power transmission shaft and formation vacuum circuit-breaker divide-shut brake.Generally all adopt Electric Machine Control, if motor is malfunctioning or when breaking down, just can use lever operated, when the motor shaft of motor rotates, for keeping handle can not rotate with it, handle is connected with the connector that passes through between the power transmission shaft, be interval with convex tendon on this connector and the inner ring that power transmission shaft is connected, and be provided with convex tendon on the connected side face of power transmission shaft equally, and when the motor shaft of motor rotates, power transmission shaft and connector idle running, handle neither can rotate with it, and after long-time, connector and power transmission shaft block easily, thereby can't realize idle running.
Summary of the invention
At the deficiency that prior art exists, the utility model provides the anti-inversion organization of the lever operated device of a kind of working stability vacuum circuit-breaker.
For achieving the above object, the utility model provides following technical scheme: the anti-inversion organization of the lever operated device of a kind of vacuum circuit-breaker, include establish and handle and power transmission shaft between connector, one end of connector and handle clamping, the other end and power transmission shaft are sheathed, be evenly equipped with ratchet on described connector and the inner peripheral surface that power transmission shaft is connected, be provided with at least one group of locating part between power transmission shaft and the connector inner peripheral surface.
Adopt technique scheme, spacing by locating part and ratchet between connector and the power transmission shaft, when making the motor-driven power transmission shaft, driving head can't be implemented rotation, handle just can not rotate thereupon yet, realize the function of the anti-reversing of handle, working stability can not block or malfunctioning owing to using for a long time to cause.
The utility model further is set to: be provided with the locating part installing rack between the inner peripheral surface of connector and the power transmission shaft, locating part places on this installing rack.
Adopt technique scheme, make on the one hand spacing being supported also can drive power transmission shaft on the other hand by installing rack.
The utility model is implemented further to be set to: locating part is the top pawl, and the top pawl includes hinged end and compresses end, and it compresses end and conflicts with the ratchet on the connector inner peripheral surface, and hinged end and installing rack are hinged, and compressing of installing rack and top pawl is provided with spring between the end.
Adopt technique scheme, simple in structure, compact, and also the setting of spring can make locating part conflict with ratchet always.
The utility model further is set to: the tooth head of the ratchet on the connector inner peripheral surface is arranged clockwise.
Adopt technique scheme, easy to process.
Below in conjunction with accompanying drawing the utility model is further described:
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
The anti-inversion organization of the lever operated device of a kind of vacuum circuit-breaker as shown in Figure 1 and Figure 2, include establish and handle 1 and power transmission shaft 2 between connector 3, one end of connector 3 and handle 1 clamping, the other end and power transmission shaft 2 are sheathed, be evenly equipped with ratchet 31 on connector 3 and the inner peripheral surface that power transmission shaft 2 is connected, the tooth head of the ratchet 31 on connector 3 inner peripheral surfaces is arranged clockwise, need to prove, this ratchet 31 also can be counterclockwise arrangement, both can with the switched in opposite of motor shaft; Prevent reversing of handle 1 during transition for making motor be in operation, power transmission shaft 2 is provided with at least one group of locating part 4 with being connected between 3 inner peripheral surfaces.Pass through the spacing of locating part 4 and ratchet 31 between connector 3 and the power transmission shaft 2, when making the motor-driven power transmission shaft, driving head 3 can't be implemented rotation, handle 1 just can not rotate thereupon yet, realize the function of handle 1 anti-reversing, working stability can not block or malfunctioning owing to using for a long time to cause.
In the utility model embodiment, be provided with locating part installing rack 5 between the inner peripheral surface of connector 3 and the power transmission shaft 2, locating part 4 places on this installing rack 5.Locating part 4 is the top pawl, the top pawl includes hinged end 41 and compresses end 42, it compresses end 42 and conflicts with the ratchet 31 on connector 3 inner peripheral surfaces, hinged end 41 is hinged with installing rack 5, compressing between the end 41 of installing rack 5 and top pawl is provided with spring 6, the setting of spring 6 can make the end 42 that compresses of locating part 4 conflict with ratchet 31 always, keeps spacing with this.
