Abstract
The utility model discloses a padlock locking device for a ground switch of a switch cabinet. The padlock locking device comprises a mounting base plate, a lock latch plate, a shaft pin, an opened check ring and a padlock, wherein the mounting base plate is fixed on the body of the switch cabinet, an operating round hole is formed on the plate face of the mounting base plate, the lock latch plate can rotate around the shaft pin, and the opened check ring is fixed at the lower end of the shaft pin. The lock latch plate and the mounting base plate are locked by the padlock, and simultaneously the operating hole of the ground switch is covered by the lock latch plate, so that the device achieves the reliable locking of the ground switch and meets the locking requirement for administrative management in a nuclear power plant. The padlock locking device has the characteristics of simple structure, flexible operation, high interlocking reliability and the like.
Description
Technical field
The utility model relates to a kind of device that switch cabinet grounding switch is locked.
Background technology
Nuclear power plant need be provided with padlock for satisfying administrative locking requirement on the earthed switch controller.Existing design can only realize the interlocking between device interior earthed switch and main switch, can not satisfy the administrative locking requirement of nuclear power plant.
Summary of the invention
In order to solve the problem of above existence, the utility model provides a kind of switch cabinet grounding switch padlock locking device, and its technical scheme of taking is:
This device comprises installation seat plate, locking board, pivot pin, split washer and padlock, installation seat plate is fixed on the switch cabinet body, have operation circular hole identical with earthed switch handle hole shape and that the position is corresponding on the plate face of installation seat plate, have the small sircle hole of position correspondence in the bending up and down of installation seat plate inboard, the left end of locking board is connected to up and down between the bending of installation seat plate, and pivot pin passes the small sircle hole of bending from top to bottom successively, the small sircle hole of locking board and following bending, make locking board can rotate and can block the operation circular hole of installation seat plate around pivot pin, split washer is fixed on the pivot pin lower end, and bottom near bending under the installation seat plate, have slotted hole I in the right side bending of installation seat plate, have in the right side bending of locking board with installation seat plate on the identical slotted hole II of slotted hole I shape, when the bending of the right side of locking board snapped onto the right side bending of installation seat plate, padlock can pass slotted hole I simultaneously and slotted hole II locks locking board and installation seat plate.The quantity of padlock is 3.
The utility model is by padlock locking locking board and installation seat plate, block the earthed switch handle hole by locking board simultaneously, realized reliable locking, satisfy the administrative locking requirement of nuclear power plant fully earthed switch, has simple in structure, flexible operation, characteristics such as it is reliable to interlock.
Description of drawings
Structural representation when Fig. 1 locks for the utility model padlock;
Structural representation when Fig. 2 unlocks for the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As depicted in figs. 1 and 2, installation seat plate 1 usefulness standard component is fixed on the switch cabinet body 6, and near the earthed switch handle hole.Have operation circular hole 10 on the plate face of installation seat plate 1, operation circular hole 10 is identical with earthed switch handle hole shape and the position is corresponding, does not therefore hinder the operation of butt joint ground switch.Have the small sircle hole of position correspondence and up/down perforation in the bending up and down of installation seat plate 1 inboard, the left end of locking board 2 is connected to up and down between the bending of installation seat plate 1, and pivot pin 3 passes the small sircle hole of small sircle hole, locking board 2 and the following bending of bending from top to bottom successively, and locking board 2 can be around pivot pin 3 rotations.Split washer 4 is fixed on pivot pin 3 lower ends, and near the bottom of 1 time bending of installation seat plate, pivot pin 3 is carried out the spacing of vertical direction.Have slotted hole I8 in the right side bending of installation seat plate 1, have in the right side bending of locking board 2 with installation seat plate 1 on the identical slotted hole II9 of slotted hole I8 shape, they are used for adorning padlock 5 as lockhole.
As shown in Figure 1, when this device carries out the padlock locking, locking board 2 around pivot pin 3 to right rotation, when locking board 2 rotates to when overlapping with the plate face of installation seat plate 1, the right side bending of locking board 2 snaps onto the right side bending of installation seat plate 1, the slotted hole II9 of locking board 2 overlaps with slotted hole I8 on the installation seat plate 1, locking board 2 blocks the operation circular hole 10 of installation seat plate 1 simultaneously, and then make the earthed switch handle hole by shutoff, this moment with 3 padlock 5 is passed slotted hole I8 simultaneously and slotted hole II9 locks locking board 2 and installation seat plate 1, and the padlock of finishing the ground connection switch operation device locks.
As shown in Figure 2, when releasing that this device locks, pull down 3 padlocks 5, with locking board 2 around pivot pin 3 to anticlockwise, the operation circular hole 10 and the earthed switch handle hole that expose installation seat plate 1, can come the operational grounding switch this moment by the earthed switch operating axis 7 that the earthed switch handle hole faces.
