Abstract
The utility model belongs to power transmission and distribution equipment, and relates to a tool in primary phase checking process of a centrally mounted switchgear, particularly to a sliding type insulating tool specialized for primary phase checking. The sliding type insulating tool comprises a body. The back end of the body is provided with a crossbeam. A screw mechanism which can drive the crossbeam and the body to perform relative movement is arranged between the crossbeam and the body. The screw mechanism is arranged on the crossbeam. Two sides of the crossbeam are provided with positioning pins which can telescope transversely. The positioning pins can be matched with the pin holes at two side columns of the switchgear. Two sides of the body are provided with side plates. The front end of each side plate is provided with a shift fork. The shift forks can drive valve mechanism transmission pins which are arranged on the switchgear. The sliding type insulating tool provided by the utility model can stably support the switchgear valve and effectively ensures a fact that the switchgear valve is always in an open state in the primary phase checking process.
Description
Technical field
The utility model belongs to equipment for power transmission and distribution, relates to a kind of instrument in nuclear phase process of central switch cabinet, specifically nuclear phase special isolation instrument of a kind of slidingtype.
Background technology
Nuclear phase of central switch cabinet is the important step of inspection work before power transmission, consistent to guarantee transmission line phase sequence.In the process of nuclear phase, switch cabinet shutter is the state in opening always.Traditional nuclear phase guarantees that with insulating bar supporting switch cabinet valve baffle plate switch cabinet shutter is in opening, but easily because of weak, causes slip, affects nuclear phase.
So need a kind ofly can to make switch cabinet shutter stable, special isolation instrument in opening reliably always in a nuclear phase process.
Summary of the invention
Problem to be solved in the utility model be to provide a kind of can stable support switch cabinet shutter and effectively guarantee switch cabinet shutter nuclear phase special isolation instrument of the slidingtype in opening always in a nuclear phase process.
The technical solution of the utility model is: nuclear phase special isolation instrument of a kind of slidingtype, comprise body, the rear end of described body is provided with crossbeam, is provided with the screw body that can drive crossbeam and body to relatively move between described crossbeam and body, and described screw body is arranged on crossbeam; The both sides of described crossbeam are provided with alignment pin that can transversal stretching, and described alignment pin can match with the lockpin hole on switch cubicle two heel posts; The both sides of described body are provided with side plate, and the front end of described side plate is provided with shift fork, and described shift fork can drive the valve mechanism gear pin being arranged on switch cubicle.
In technique scheme, on described body, be provided with and can make body along a plurality of wheels of handcart switch cabinet handcart guide rail walking.
In technique scheme, on described crossbeam, be provided with the handle that can drive alignment pin flexible.
In technique scheme, described screw body is controlled by handle.
The utility model has the advantages that: this tool construction is simple, easy to use, reduced staff quantity, improved operating efficiency, reduced the danger of staff's low-voltage electric shock and equipment line to line fault.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is front view of the present utility model;
Fig. 2 is vertical view of the present utility model;
Fig. 3 is left view of the present utility model;
Embodiment
As shown in the figure: nuclear phase special isolation instrument of a kind of slidingtype, comprise body 1, the rear end of described body is provided with crossbeam 2, is provided with and is arranged on crossbeam 2 upper screw rod mechanisms 8 between described crossbeam and body 1, and described screw body 8 drives crossbeam 2 and body 1 to relatively move; The both sides of described crossbeam 2 are provided with alignment pin 4 that can transversal stretching, and described alignment pin 4 matches with the lockpin hole B on switch cubicle two heel posts, on described crossbeam 2, is provided with handle 3; The both sides of described body 1 are provided with side plate 6, and the front end of described side plate 6 is provided with shift fork 7.
On described body 1, be provided with 4 wheels 5, described wheel 5 is walked along handcart switch cabinet handcart guide rail.
During work, by handle 3, control the length that alignment pin 4 stretches out, alignment pin 4 matches and makes crossbeam 2 limited with lockpin hole B on switch cubicle two heel posts, crossbeam 2 can not move forward, by handle 3, control screw body 8 again, body 1 is moved forward, and then make shift fork 7 drivings be arranged on the valve mechanism gear pin A on switch cubicle, valve mechanism gear pin A driving switch cabinet valve is opened.
