Description

Switch operation mechanism anti-misoperation locking device

Technical field

The utility model relates to a kind of electric power apparatus examination instrument, particularly relates to a kind of switch operation mechanism anti-misoperation locking device.

Background technology

After the mechanical coding lock of 110 kilovolts of Xin Ta transformer station CS8-6D type switch operation mechanism error-proof devices hangs up, guide vane end stop still has movable leeway, causes knife switch operation mechanism to lose locking, easily causes misoperation.

11 0 k V Xin Ta transformer station 10 k V capacitor CS8-6D type switch operation mechanisms adopt Mechanical ring latch formula closedown mode, between disconnecting link guide vane end stop and operating grip, hang up five anti-mechanical coding locks.Find when equipment operating, five anti-mechanical coding locks are locked and effectively can not be limited guide vane end stop, when not unblanking, still can operate disconnecting link.Main cause is because there is gap with guide vane end stop between two crotches of five anti-mechanical coding locks, after hanging up five anti-mechanical locks, the spacing handle of disconnecting link guide vane end stop swings angle about 20 °, stroke 40mm, spacing handle button moving displacement 12mm, the spacing hole depth 10mm of connecting rod, spacing handle head and connecting rod spacing hole depart from and lose limit function (see figure 5).

Summary of the invention

For above technical problem, the utility model provides that a kind of structure is simple, easy and simple to handle, the switch operation mechanism anti-misoperation locking device of good limit effect.

The technical solution of the utility model is: a kind of switch operation mechanism anti-misoperation locking device, comprise the operating grip for carrying out spacing spacing handle, five anti-Mechanical ring latches and capacitor disconnecting link to capacitor disconnecting link, operating grip is provided with the bayonet lock of that can pull up and down, a fixing spacing handle, bayonet lock is with the anti-mechanical lockhole of extension five.

Further, above-mentioned bayonet lock comprises bayonet lock axle and bayonet lock cover, bayonet lock spring is provided with in bayonet lock cover, pullover I, pullover I of the L shape that the upper end that bayonet lock overlaps is established is provided with five anti-mechanical coding lockholes, and bayonet lock axle overlaps through bayonet lock and is set in bayonet lock spring, bayonet lock axle and bayonet lock spring are provided with spacing block set, bayonet lock axle also has pullover II of a L shape, and pullover II has five anti-mechanical coding lockholes, and pullover II and described pullover I matches hangs over five anti-mechanical coding locks in five anti-mechanical coding lockholes.

The limiting card head width of above-mentioned spacing handle (1) is 13mm.

Beneficial effect:

1. the utility model is by the bayonet lock axle bumper position guide vane end stop of bayonet lock, and rigid very close to each other; Spacing function like this obtains reinforcement.

2. the spacing dop of spacing handle (1) is long is 13mm, and being greater than original position moves 12mm, also obtains reinforcement to spacing function further.

Accompanying drawing explanation

Fig. 1 is the structural representation of bayonet lock of the present utility model;

Fig. 2 is that the padlock of this bayonet lock of the present utility model enters view;

Fig. 3 is standoff features figure of the present utility model;

Fig. 4 is the using state figure of Fig. 1;

Fig. 5 is the structural representation of the disconnecting link stopping means of prior art;

The spacing handle of 1-; 2-bayonet lock; 3-operating grip; The anti-mechanical coding lock of 4-five;

201-bayonet lock axle; 202-bayonet lock spring; 203(or 203 ^/)-five anti-mechanical coding lockholes; 204-bayonet lock cover.

Be described further below in conjunction with accompanying drawing:

In the utility model, the noun of locality such as " upper and lower, left and right " of use typically refers to reference to upper and lower, left and right shown in the drawings; " inside and outside " refers to profile inside and outside relative to each parts itself.

See accompanying drawing 1 and Fig. 2, in Fig. 1, bayonet lock 2 forms primarily of bayonet lock cover 204 and bayonet lock axle 201, bayonet lock spring 202 is had in bayonet lock cover 204, bayonet lock axle 201 is provided with spacing block set and is enclosed within bayonet lock spring 202, bayonet lock axle 201 is through bayonet lock cover 204, the edge of lower end is stretched axle and is carried out spacing to guide vane end stop 1, and bayonet lock cover 204 and bayonet lock axle 201 are respectively equipped with pullover I and pullover II, pullover I and pullover II of L shape and are provided with five anti-mechanical coding lockhole 203 and five anti-mechanical coding lockholes 203 ^/, in Fig. 1 bayonet lock cover 204 turn left 90 ° time be exactly Fig. 2, i.e. five anti-mechanical coding lockhole 203 and five anti-mechanical coding lockholes 203 ^/coordinate side by side for hanging five anti-mechanical coding lockholes.

See Fig. 4 when using state, five anti-mechanical coding locks are opened, bayonet lock axle 201 is to pull-up, the edge of lower end is stretched axially, then can operate guide vane end stop 1, when needing locking after guide vane end stop completes, when bayonet lock axle 201 turns left, bayonet lock axle 201 is under the effect of bayonet lock spring, and bayonet lock axle 201 carries out spacing to guide vane end stop 1 downwards, five anti-mechanical coding lockhole 203 and five anti-mechanical coding lockholes 203 ^/side by side, hang up the anti-mechanical coding lockhole of extension five simultaneously and complete disconnecting link locking.

See Fig. 3, guide vane end stop 1 comprises a spacing dop, fixing hole and spacing handle.

Embodiment, operates as follows: open five anti-mechanical coding locks 4, be pulled to above guide vane end stop 1 by the bayonet lock axle 201 of bayonet lock 2, then can the spacing handle of pinching guide vane end stop 1, and the spacing dop of guide vane end stop 1 and switch operation connecting rod are departed from, and disconnecting link can operate; Disconnecting link puts in place through operating grip 3 operation, the spacing dop of guide vane end stop 1 blocks switch operation connecting rod, put down bayonet lock, and pin bayonet lock 2 with five anti-mechanical coding locks 4 and make it upwards not mention, bayonet lock 2 gapless withstands guide vane end stop 1, guide vane end stop 1 blocks switch operation connecting rod, disconnecting link locking, can not rotating operation.

Meanwhile, can the spacing dop of guide vane end stop 1 be also 13mm, move 12mm owing to being greater than original position, strengthening further obtaining spacing function.

Below preferred implementation of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned execution mode; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection range of the present utility model.
