Description
Technical field
The utility model belongs to handcart-type high-pressure vacuum breaker attachment technique field, is specifically related to a kind of chassis car interlock of handcart type breaker.
Background technology
The chassis effect of car interlock on the handcart-type high-pressure vacuum breaker is known, guarantees that promptly handcart type vacuum circuit breaker can not closed a floodgate in the moving process of test position to test position or by the isolated location by the service position.The interlock of the handcart-type high-pressure vacuum breaker that China utility model patent Granted publication CN201266572Y recommends can be brought into play aforesaid effect, and eliminated the shortcoming that discloses the combined floodgate interlocker among the CN2674619Y, specifically can be referring to the background technology hurdle of the specification of CN201266572Y the 1st page.
The disclosed technology contents of CN201266572Y is: a blocking lever (patent claims locking part) is installed on the car of chassis, the chassis car is in the moving process from the service position to the test position or from the isolated location to the test position, blocking lever is that rotating shaft is rotated with the interlocking shaft that is fixed on the car of chassis, driving connecting plate (patent claims push rod) by a series of auxiliary connection rotates, and then drive by connecting plate circuit breaker operation mechanism separating brake dropout semiaxis dial plate (patent claims presser feet), thereby make the circuit breaker operation mechanism separating brake.By the extension spring effect of (patent claims spring), make separating brake dropout semiaxis remain in gate-dividing state simultaneously, under this state, because the interlocking effect of circuit breaker operation mechanism can't be closed a floodgate operating mechanism.Therefore, realize only allowing circuit breaker to close a floodgate by chassis car interlock, and can not close a floodgate by separating brake at circuit breaker between these two positions in service position and isolated location separating brake.Again because when the mobile chassis car, chassis car interlock must make the circuit breaker operation mechanism separating brake, moves the function that only permission is carried out so also reached the chassis car under gate-dividing state.
But, the technical scheme that aforesaid CN201266572Y provides still has two place's shortcoming: the one, and blocking lever promptly is connected with the connecting axle screw with screw with interlock upper boom (patent claims lower connecting plate), because they are positioned at the inside of circuit breaker, no matter therefore be that connection or the dismounting during in inspection when assembling is all very difficult; The 2nd, when blocking lever does not link to each other with the interlock upper boom, owing to the effect of spring makes circuit breaker operation mechanism continue to remain in gate-dividing state, and be can't be to the debugging of circuit breaker under gate-dividing state, conventional disposal options is to apply the power that presses down for artificially the interlock upper boom temporarily, thereby causes trouble for the operation when debugging.
Summary of the invention
It is a kind of when circuit breaker and the assembling of chassis car that task of the present utility model is to provide, need not to use the simple operation that embodies when installing, under gate-dividing state, can not continue the chassis car interlock of avoiding the handcart type breaker that the Installation and Debugging to circuit breaker impact is used in the separating brake dropout semiaxis effect of circuit breaker operation mechanism because of the effect of spring with inspection by means of the parts such as the connecting pin screw just can directly cooperate the interlock upper boom with blocking lever.
Task of the present utility model is finished like this, a kind of chassis car interlock of handcart type breaker, described handcart type breaker comprises chassis car and the circuit breaker operation mechanism with interlocking shaft, circuit breaker operation mechanism comprises a pair of supporting plate that is set parallel to each other and is arranged on the separating brake dropout semiaxis between the pair of brackets plate and top that be positioned at supporting plate rotationally, one end of this separating brake dropout semiaxis has a separating brake dropout haptic element, described chassis car interlock comprises the blocking lever that is fixed on the described interlocking shaft, the interlock upper boom, spring and interlocking bent plate, be characterised in that: described interlock upper boom slides up and down to be arranged on the wherein outside of one piece of supporting plate in the described pair of brackets plate, the upper end of this interlock upper boom is insinuated between the pair of brackets plate and is corresponding with described separating brake dropout haptic element, and the lower end is corresponding with described interlocking bent plate, the upper end of spring and interlock upper boom are fixed, lower end and supporting plate are fixed, one end pivoting of described interlocking bent plate is arranged on the inwall of described supporting plate, the other end constitutes free end, and constitute a bending part and stop pin at this free end, wherein, bending part matches with described blocking lever, and it is outer and corresponding with the lower end of described interlock upper boom to stop that pin is stretched over described supporting plate.
In a specific embodiment of the present utility model, the top of described supporting plate and offer a pin-shifting hole at position corresponding to described separating brake dropout haptic element, the upper end of described interlock upper boom and be fixed with a finger at position corresponding to described pin-shifting hole, this finger is insinuated between the described pair of brackets plate, and corresponding to the below of described separating brake dropout haptic element.
In another specific embodiment of the present utility model, offer at least one pair of guide runner on the described interlock upper boom, be provided with the pilot pin that quantity equates with the quantity of guide runner on the outer wall of described supporting plate and corresponding to the position of described guide runner, pilot pin is insinuated in the guide runner.
In another specific embodiment of the present utility model, the lower end bending of described interlock upper boom constitutes a folding arm, offer one in the bottom of described supporting plate and stop the pin hole, the end that stops pin of described interlocking bent plate is through stopping the pin hole and be stretched over the outside of supporting plate and corresponding to the below of described folding arm.
In another specific embodiment of the present utility model, the inwall of described supporting plate is installed with an interlocking bent plate support, and described interlocking bent plate is arranged on the interlocking bent plate support by the pivot pivot.
Also have in the specific embodiment of the present utility model, described blocking lever constitutes an interlocking lever arm at the end towards described interlocking bent plate, and described bending part matches with the interlocking lever arm.
More of the present utility model and in specific embodiment, described bending part is formed in the described free-ended end of described interlocking bent plate, and the described pin that stops is formed in the described free-ended sidepiece of described interlocking bent plate.
In of the present utility model and then specific embodiment, described supporting plate is provided with a locking device that stops foot control system that is used for described interlocking bent plate.
