Abstract
The utility model provides an interlock for circuit breaker connects a fixed plate on mechanism's curb plate, an output macroaxis end connection spacing turning arm, the fixed plate is equipped with the slide opening, gliding set of post about the slide opening is established, and cover support connnection interlocking board, interlocking board upper portion is equipped with flat baffle, the middle part is equipped with perpendicular baffle, the articulated rotatory turning arm in lower part, and rotatory turning arm has a turning, and on the corner articulated the fixed plate, rotatory another articulated push pedal of turning arm was during the combined floodgate spacing turning arm prevents the up -and -down motion of flat baffle, during the separating brake erect the rotate clockwise that the baffle prevents the combined floodgate pole. The effect: inject with the operation of circuit breaker equipment in relevancy, realized between each item operation the function of shutting each other, the structure is simple and clear, spare part is small in quantity.
Description
Technical field
This utility model belongs to chopper expanded application field, relates to the interlock forbidding arbitrarily operating with chopper associated device.
Background technology
After chopper is connected with associated device, for safety or the needs of other side, chopper does not allow operation when "on" position with chopper associated device,Chopper gate-dividing state, simultaneously with chopper associated device in operation time do not allow chopper to carry out closing operation, but possible operation in the case of somebody is unwitting, or know people's maloperation due to negligence of rule of operation, case above is likely to cause the accident, harm personnel and production safety.
Utility model content
The purpose of this utility model is to provide a kind of interlock, solves chopper and does not allow when "on" position associated device to operate；The interlock of closing operation can not be carried out with chopper associated device chopper when operation.
For achieving the above object, this utility model is by the following technical solutions: a kind of chopper interlock, mechanism's side plate connects a fixed plate, export big shaft end head and connect a spacing connecting lever, described fixed plate is provided with slide opening, slide opening sets the sleeve column slided up and down, sleeve column connects interlock plate, described interlock plate top is provided with flat baffle plate, middle part is provided with perpendicular baffle plate, lower hinge rotates connecting lever, rotate connecting lever and have a turning, corner is hinged in fixed plate, rotate the hinged push pedal in connecting lever other end, during combined floodgate, described spacing connecting lever stops the up and down motion of flat baffle plate, during separating brake, described perpendicular baffle plate stops rotating clockwise of combined floodgate bar.
Described push pedal is bearing pin with the connector of rotation connecting lever.
The corner of described rotation connecting lever and the connector of fixed plate are bearing pin.
Described rotation connecting lever is bearing pin with the connector of interlock plate bottom.
The beneficial effects of the utility model: limit the operation with chopper associated device, i.e. chopper does not allow when closing position to operate with chopper associated device, and only chopper just allows it to operate when open position；Limiting the closing operation of chopper, when i.e. operating with chopper associated device, chopper does not allow to carry out closing operation, just allows chopper to carry out closing operation, improve the safety of breaker operator when only stopping operation with chopper associated device.This device is simple, convenient, achieve the function of mutual locking between operations, and structure is simple and clear, amount of parts is few.

Detailed description of the invention
Being described principle of the present utility model and feature below in conjunction with accompanying drawing, example is served only for explaining this utility model, is not intended to limit range of the present utility model.
As shown in Figure 1: a kind of chopper interlock, it is characterized in that connecting a fixed plate 1 on mechanism's side plate 2, export big axle 4 termination and connect a spacing connecting lever 3, described fixed plate 1 is provided with slide opening 12, slide opening 12 sets the sleeve column 11 slided up and down, sleeve column 11 connects interlock plate 5, described interlock plate 5 top is provided with flat baffle plate 13, middle part is provided with perpendicular baffle plate 14, bottom connects rotation connecting lever 8 by bearing pin 6, rotate connecting lever 8 and have a turning, corner is hinged in fixed plate 1 by bearing pin 7, rotate connecting lever 8 other end and connect push pedal 9 by bearing pin 10, during combined floodgate, described spacing connecting lever 3 stops the up and down motion of flat baffle plate 13, during separating brake, described perpendicular baffle plate 14 stops rotating clockwise of combined floodgate bar 15.
This utility model specific works principle:
As shown in Figure 2: when in figure, breaker mechanism is in closing position, spacing connecting lever 3 is pressed on interlock plate 5, interlock plate 5 is made not move up and down, the rotation connecting lever 8 being connected with interlock plate 5 is in can not kinestate, then with rotate that the push pedal 9 that is connected of connecting lever 8 is also at can not kinestate, hole in push pedal 9 cannot and overlap with the handle hole of chopper associated devices, therefore reaches chopper and does not allow the purpose of operation with chopper associated devices in "on" position.
As shown in Figure 3: when in figure, breaker mechanism is in open position, spacing connecting lever 3 is rotated clockwise to shown position with exporting big axle 4 in mechanism, now push pedal 9 moves horizontally along direction of operating, push pedal 9 is rotated connecting lever 8 by bearing pin 10 and turns clockwise, rotating connecting lever 8 drives interlock plate 5 to move upward by bearing pin 6, when walking to shown position, interlock plate 5 withstands combined floodgate bar, make combined floodgate bar can not carry out the closing operation turned clockwise, thus when reaching the operation with chopper associated devices, chopper can not carry out the purpose of closing operation.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all within spirit of the present utility model and principle, any amendment of being made, equivalent, improvement etc., within should be included in protection domain of the present utility model.
