Abstract
The utility model relates to a kind of handcart grounding switch operation valve locking device, it is characterized in that it is made up of interior latch fitting and outer latch fitting two parts, interior latch fitting is arranged on the operation valve of handcart grounding switch cabinet, outer latch fitting is arranged on outside the operation valve of handcart grounding switch cabinet, its advantage is, no matter grounding switch is in point position or in co-bit, can both plays the effect of locking grounding switch operation valve, thus can avoid the generation of misoperation fault.
Description
Technical field
The utility model relates to a kind of safety device of power equipment, particularly a kind of handcart grounding switch operation valve locking device.
Background technology
The effect of handcart grounding switch is when the primary equipment such as circuit, switch overhauls, by repair apparatus two ends reliable ground, to ensure the safety of maintainer and repair apparatus.The separating brake of handcart grounding switch and closing operation have come with the operation valve that crank stretches into hands injured, and operate valve all the time in open state, therefore, no matter grounding switch is in point position or co-bit, all likely occur in maintenance process, crank to be stretched into the situation that operation valve carries out misoperation by mistake, thus cause security incident to upkeep operation personnel or relevant device.
Summary of the invention
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art, provides a kind of handcart grounding switch to operate valve locking device.
Technical solution of the present utility model is: a kind of handcart grounding switch operation valve locking device, is characterized in that it is made up of interior latch fitting and outer latch fitting two parts: interior latch fitting is by seat board and be arranged on seat board edge and lock nose perpendicular to seat board is formed; Outer latch fitting is by with the base of chute, seat board and lock nose up and down and form, its seat board is vertically set on base, seat board is arranged respectively upper and lower two lock noses perpendicular to seat board, stagger about the lockhole position of lock nose and lower lock nose, be provided with horizontal gap with the seat board of lower lock nose parallel position.
Described interior latch fitting is arranged on the operation valve of handcart grounding switch cabinet, and its seat board is embedded in operation valve, and lock nose stretches out from operation valve, and interior latch fitting can slide up and down along operation valve.
Described outer latch fitting is arranged on outside the operation valve of handcart grounding switch cabinet, and its base nets edge on door before being fixed on hands injured by bolt through chute, and outer latch fitting can horizontally slip along bolt.
The utility model has the advantage of, no matter grounding switch is in point position or in co-bit, can both plays the effect of locking grounding switch operation valve, thus can avoid the generation of misoperation fault, has ensured the safety of the person and equipment; Outer latch fitting locks the setting of nose and the position difference that horizontally slips up and down, can while lock operation valve, and display grounding switch divides the immediate status of position or co-bit, the judgement of handled easily personnel and operation.

embodiment
Be described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, outer latch fitting, by with the base 2 of chute 1, seat board 3 and lock nose up and down and form, staggers about the lockhole position of lock nose 4 and lower lock nose 5, is provided with horizontal gap 6 with the seat board of lower lock nose parallel position.Base and upper and lower lock nose are all positioned at the same side of seat board and perpendicular with seat board.
As shown in Figure 2, interior latch fitting is by seat board 7 and be arranged on seat board edge and lock nose 8 perpendicular to seat board is formed.Interior latch fitting is arranged on the operation valve 9 of handcart grounding switch cabinet, and its seat board is embedded in operation valve, and lock nose stretches out from operation valve, and interior latch fitting can slide up and down along operation valve, sees Fig. 3,4,5.
Outer latch fitting is arranged on outside the operation valve of handcart grounding switch cabinet, and its base nets edge on door 11 before being fixed on hands injured by bolt 10 through chute, and outer latch fitting can horizontally slip along bolt, sees Fig. 3,4,5.
When handcart grounding switch is in point position at ordinary times, interior latch fitting slides into operation valve top, and outer latch fitting slides into left side, and now, the lock nose of latch fitting is overlapping with the nose of locking of outer latch fitting, and can lock locking, sees Fig. 3.
When grounding switch is dropped into co-bit by needs, open lockset, outer latch fitting is slid into right side (see figure 4), interior latch fitting is slid on the downside of operation valve, now crank can be stretched into operation valve and carry out closing operation; After being taken out by crank, then the lock nose outer latch fitting being slid into interior latch fitting is left overlapping with the lower lock nose of outer latch fitting, keeps grounding switch to divide a state, see Fig. 5 after locking.
