Abstract
The utility model relates to a machine misoperation-preventive locking device, i.e., a misoperation-preventive locking device used in a switching operation. The locking device comprises a lockset, a shaft pin, a movable support, a chuck, and a disconnecting switch vertical connecting rod. One end of the movable support is mounted on a steel channel of a disconnecting switch operation mechanism. The lower end of the shaft pin penetrates through the lockset and the steel channel and is fixed on the chuck. The chuck is clamped on the disconnecting switch vertical connecting rod through a fixing nut. A positioning mark is arranged at the position where the chuck and the disconnecting switch vertical connecting rod are fixed. The locking device of the utility model has a reasonable and practical structure. The chuck of the locking device is fixed on the disconnecting switch vertical connecting rod at a height that cannot be changed. The horizontal position changes of the chuck can be discovered and the horizontal position of the chuck can be adjusted. The shaft pin of the lockset is enabled to insert into a shaft hole of the chuck for a proper depth. Accordingly, the normal operation of the locking device can be guaranteed; the misoperation problem cannot be generated; and the working efficiency is increased.
Description
technical field
The utility model relates to a kind of mechanical anti-misoperation locking device, is anti-misoperation locking device in a kind of grid switching operation.
Background technology
At present, what mechanical locking device was installed at the scene is comprised of lockset, chuck, travel(l)ing rest, isolating switch vertical links, locking key usually, travel(l)ing rest is arranged on the channel-section steel of isolator operating mechanism, lockset is arranged on travel(l)ing rest, lock collar is arranged on the vertical links of isolating switch, and locking device forms interlock and blocking function with the pin of lockset and the axis hole of chuck.When the lockset pivot pin extension elongation of locking device is too much or when very few, the locking key just can not be opened locking, the pivot pin of lockset just can not be mentioned, and operation just can not be carried out.The position displacement that lock collar in use occurs usually due to locking device is highly incorrect, the degree of depth that causes the locking pin to go down in the lock collar axis hole is improper, make the locking key lock of not opening, grid switching operation can not normally carry out, extended the operating time, extend equipment and stopped electric power feeding time, time and the quality of overhaul of the equipments have been affected, affected indirectly electricity sales amount, cause the generation of anti-misoperation locking being carried out to the release behavior, when operation disruption processing abnormal conditions occur, easily gone to the wrong way again interval, misoperation occurs, and to safety in production, has caused hidden danger.
Summary of the invention
This reality is novel provides anti-misoperation locking device in a kind of grid switching operation, and it can solve the problem that prior art is prone to misoperation effectively.
The technical solution of the utility model realizes by following measures: a kind of locking device, it comprises lockset, pivot pin, travel(l)ing rest, chuck, the isolating switch vertical links, travel(l)ing rest one end is arranged on the channel-section steel of isolator operating mechanism, the pivot pin lower end is through lockset and channel-section steel, the pivot pin lower end is fixed on chuck, chuck is stuck on the vertical links of isolating switch by hold-down nut, at the isolating switch vertical links, there is telltale mark fixing position to chuck, limited location hole on chuck, stop nut is connected chuck by spacing hole with the isolating switch vertical links.
The utility model is rational in infrastructure and practical, the height that the chuck of locking device is fixed on the isolating switch vertical links is not changed, and can find the variation of chuck horizontal level and be adjusted, the degree of depth that the pivot pin of lockset is inserted in the chuck axis hole is suitable, guarantee the normal running of locking device, not there will be the problem of misoperation, improved operating efficiency.
The accompanying drawing explanation
Accompanying drawing 1 is main TV structure schematic diagram of the present utility model.
Being encoded in figure: 1 is lockset, and 2 is pivot pin, and 3 is travel(l)ing rest, and 4 is chuck, and 5 is the isolating switch vertical links, and 6 is set bolt, and 7 is telltale mark, and 8 is stop nut.
Embodiment
The utility model is not subject to the restriction of following embodiment, can with actual, below in conjunction with embodiment and accompanying drawing, to the utility model, be further described according to the technical solution of the utility model:
As shown in Figure 1, anti-misoperation locking device in this grid switching operation, comprise lockset 1, pivot pin 2, travel(l)ing rest 3, chuck 4, isolating switch vertical links 5, travel(l)ing rest 3 one ends are arranged on the channel-section steel of isolator operating mechanism, pivot pin 2 lower ends are through lockset 1 and channel-section steel, pivot pin 2 lower ends are fixed on chuck 4, chuck 4 is stuck on the vertical links 5 of isolating switch by hold-down nut 6, there is telltale mark 7 position fixing at chuck 4 and isolating switch vertical links 5, limited location hole on chuck 4, stop nut 8 is connected chuck 4 by spacing hole with isolating switch vertical links 5, so just can make the position of chuck on the isolating switch vertical links keep fixing, convenient operation.
Claims (1)
