Abstract
The utility model relates to an interlocking device capable of preventing a grounding switch from false switching. The interlocking device comprises a stop shielding part hinged on the rear side of a grounding switch control handle insertion hole panel, a linked locking lever arranged on the rear side of the stop shielding part and capable of translating forwards and backwards, and a shift lever arranged on the rear side of the linked locking lever, wherein a poking and rotating part capable of driving the stop shielding part to rotate around the hinged axis to open or close a grounding switch control handle insertion hole is fixedly connected to the front side of the stop shielding part; a locking hole capable of being in inserting fit with the linked locking lever moving forwards when the stop shielding part is in a closed state is arranged on the rear side of the stop shielding part; and an elastic pushing part capable of backwardly pushing/pulling the linked locking lever is arranged between the linked locking lever and a cabinet body. The interlocking device capable of preventing the grounding switch from false switching, which is provided by the utility model, can prevent a grounding switching control rotating shaft from misoperation when a handcart is switched on, thereby protecting the grounding switch against false switching to ensure security.
Description
Technical field
The utility model relates to a kind of interlock that prevents ground cutter false switching.
Background technology
The ground cutter control rotating shaft that is positioned at operating room that the high-tension switch cabinet earthing chamber comprises cabinet, is located at the ground cutter in the cabinet and is used for controlling ground cutter on/off switch work.In order at utmost to guarantee staff's safety, the high-tension switch cabinet earthing chamber requires to have to prevent the misoperation interlock reliably, what wherein must accomplish a bit is: when handcart is in the combined floodgate operating state, for guaranteeing safety, can not handle ground cutter control rotating shaft closes a floodgate the ground cutter, have only when handcart is in the separating brake experimental state, just operably the cutter control rotating shaft is closed a floodgate the ground cutter.
Not having as yet at present preferably that interlocking device can realize above-mentioned requirements, mainly all is by staff's Artificial Control, the degree of danger height.
Summary of the invention
The purpose of this utility model is to provide a kind of interlock that prevents ground cutter false switching, and it can prevent error operations ground cutter control rotating shaft when the work of handcart combined floodgate, thereby avoids ground cutter mistake to close a floodgate, to guarantee safety.
The purpose of this utility model is achieved through the following technical solutions: a kind of interlock that prevents ground cutter false switching is characterized in that: it comprise be articulated in ground cutter control crank patchhole panel rear side end into block piece, be located at end into the block piece rear side can before and after the interlock securing rod of translation and the driving lever of being located at interlock securing rod rear side; Described front side of ending into block piece is connected with can drive to end rotating to around its jointed shaft into block piece and makes ground cutter control crank patchhole be in the rotation member of dialling of opening or cover state, end rear side into block piece and be provided with and be in when covering state ending, the lock hole of pegging graft and cooperating with the interlock securing rod that moves forward into block piece; The middle part of described driving lever is articulated on the cabinet, the front end of driving lever is extended and is provided with to the front lower place by articulated position and is used for and is located at the chute that the sliding pin of interlock locking rod rear end portion is slidingly connected, the rear end of driving lever is extended to the back upper place by articulated position, and pass the through hole that the is positioned at handcart combined floodgate service area bottom exposed portions serve that makes progress, under nature, the upwards exposed portions serve of driving lever is higher than the handcart bottom surface; Being provided with between described interlock securing rod and the cabinet can be to the elastic top push piece of pusher/draw interlock securing rod.
Operation principle of the present utility model is as follows: when handcart closes a floodgate, handcart is moved to the combined floodgate service area by the separating brake test block, when handcart bottom roof pressure making progress during exposed portions serve to driving lever, force the upwards exposed portions serve that is positioned at the driving lever front end to move down, thereby driving driving lever rotates around its jointed shaft, making the driving lever front end drive the interlock securing rod moves forward, the interlock securing rod inserts and ends in the lock hole of block piece rear side, make to end and be locked in the state of covering into block piece, at this moment, because ground cutter control crank patchhole is covered, therefore the cutter control crank can't insert ground cutter control crank patchhole over the ground the cutter control rotating shaft handle, thereby can avoid ground cutter mistake to close a floodgate.When handcart moves to the separating brake test block by the combined floodgate service area, handcart separates with the upwards exposed portions serve that is positioned at the driving lever front end, driving lever is not subjected to the roof pressure effect, the interlock securing rod is not subjected to jacking force forward, and the interlock securing rod moves under the effect of elastic top push piece backward, is separated with lock hole, make to end and unlock into block piece, can open end into block piece this moment, and ground cutter control crank is inserted ground cutter control crank patchhole, the cutter control rotating shaft manipulation of closing a floodgate over the ground.
The utility model has also been done following improvement:
Open and close for convenience and end into block piece, described group of rotation member is made of the finger that is inserted in the ground cutter control crank patchhole.
Described end being provided with to be used for making between block piece and the ground cutter control crank patchhole panel end the reset components of getting back to the state of covering into block piece automatically, thereby convenient interlock securing rod cooperates locking with lock hole on ending block piece.
Compared to prior art, advantage of the present utility model is: by the setting of interlock, thereby can prevent error operations ground cutter control rotating shaft when the work of handcart combined floodgate, close a floodgate to avoid ground cutter mistake, guarantee safety.
