Abstract
The invention discloses an automatic valve locking mechanism of a high-voltage switch cabinet. The automatic valve locking mechanism comprises a rotating arm capable of driving a valve to move, the tail end of the rotating arm is hinged to the rear lower part of a cabinet framework through a rotating arm spindle, and the front lower part of the cabinet framework is hinged to a guide-track groove plate; a connection board which moves synchronously with the rotating arm is further fixedly mounted on the rotating arm spindle, the upper end of the connection board is connected with a connection rod arranged in the longitudinal direction of the cabinet framework, and the other end of the connection board is hinged to the upper part of the guide-track groove plate through a shaft pin; and the upper part of the cabinet framework is hinged to a valve buckle plate provided with a locking slot, and when a handcart is drawn out of the cabinet framework, the valve buckle plate can be clamped on the shaft pin to lock the valve. With the adoption of the structure, the upper part of the cabinet framework is hinged to the valve buckle plate provided with the locking slot, and when the handcart is drawn out of the cabinet framework, the valve buckle plate can be clamped on the shaft pin to lock the valve, so that the valve can be prevented from being opened by misoperation, and the potential safety hazard is eliminated.
Description
?
Technical field
The present invention relates to the valve locking mechanism used in a kind of high pressure complete set of equipments, specifically a kind of high-tension switch cabinet valve automatic locking mechanism.
Background technology
At present, the high-tension switch cabinet of high pressure complete set of equipments manufacturer production does not have the valve locking mechanism that can lock valve is installed both at home and abroad, and when handcart was pulled out from cupboard, the handcart valve can be opened very easily, in case there is people's misoperation to open valve with regard to danger close.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of valve that can lock and prevents that misoperation from opening the door the high-tension switch cabinet valve automatic locking mechanism that eliminates safe hidden trouble.
In order to solve the problems of the technologies described above, high-tension switch cabinet valve automatic locking mechanism of the present invention, comprise a pivoted arm that can drive valve action, the end of pivoted arm is by the back lower place of a hinged cabinet body frame of pivoted arm rotating shaft, and the front lower place of cabinet body frame is hinged with a guide rail frid; Also fixedly mount a connecting plate with the pivoted arm synchronization action in the pivoted arm rotating shaft, the upper end of connecting plate is connected with one along the connecting rod that arranges on the cabinet body frame longitudinal direction, the other end of connecting rod is hinged on the upper end of guide rail frid by pivot pin, the top of cabinet body frame is hinged with a valve buckle that has lock slots, when handcart withdrawed from cabinet body frame, the valve buckle can be fastened on the pivot pin valve is locked.
The front end of described valve buckle and connecting rod is respectively arranged with a spigot surface that makes things convenient for the handcart straight pin to advance.
After adopting above-mentioned structure, because the top of cabinet body frame is hinged with a valve buckle that has lock slots, when handcart withdrawed from cabinet body frame, the valve buckle can be fastened on the pivot pin valve is locked, prevented that thus misoperation from opening valve, eliminated potential safety hazard.
Description of drawings
Fig. 1 is the structural representation of high-tension switch cabinet valve automatic locking mechanism of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, high-tension switch cabinet valve automatic locking mechanism of the present invention is described in further detail.
As shown in the figure, high-tension switch cabinet valve automatic locking mechanism of the present invention, comprise a pivoted arm 1 that can drive valve action, the end of pivoted arm 1 is by the back lower place of pivoted arm rotating shaft 2 hinged cabinet body frames 3, and the front lower place of cabinet body frame 3 is hinged with a guide rail frid 4; Also fixedly mount a connecting plate 5 with pivoted arm 1 synchronization action in the pivoted arm rotating shaft 2, the upper end of connecting plate 5 is connected with one along the connecting rod 6 that arranges on the cabinet body frame longitudinal direction, the other end of connecting rod 6 is hinged on the upper end of guide rail frid 4 by pivot pin 7, the top of cabinet body frame 3 is hinged with a valve buckle 8 that has lock slots, when handcart withdrawed from cabinet body frame 3, valve buckle 8 can be fastened on the pivot pin 7 valve is locked.
Further can be respectively arranged with a spigot surface 9 that makes things convenient for the handcart straight pin to advance at the front end of valve buckle 8 and connecting rod 6, two spigot surfaces can also be set in the inboard of the upper end of guide rail frid 4 U-lag.
Its operation principle is as follows:
When handcart shakes into the service position from test position, the straight pin of handcart both sides boosts valve buckle 8 and drives 4 rotations of guide rail frid simultaneously, and under the promotion of connecting rod 6, pivoted arm 1 rotates pulling mechanism opening valve, when otherwise handcart withdraws from cabinet, want to open valve, press pivoted arm 1, the pulling lower guideway frid 4 that pivoted arm 1 is rotated in connecting rod 6 rotates, but because valve buckle 8 is not raised, pivot pin 7 is in the lock slots of valve buckle 8, and guide rail frid 4 can't rotate, thereby has realized the valve lock function.
Claims (2)
