Abstract

The invention discloses a mutual inductor disassembly-assembly bracket in a switch cabinet, which comprises a height-adjustable base, an involution nut and a trapezoidal-thread screw rod, wherein a load-bearing sleeve is connected to the base in an assembly and disassembly mode; the top of the load-bearing sleeve is provided with a centripetal thrust sliding bearing; the involution nut is arranged on the sliding bearing; the trapezoidal-thread screw rod cooperates with the involution nut; the top of the screw rod is connected with a supporting plate in an assembly and disassembly mode; the lower part of the screw rod is connected with a guide sleeve in an integral mode; and a position limiting structure, which enables the guide sleeve to only rise or fall but not rotate in the load-bearing sleeve, is arranged between the guide sleeve and the load-bearing sleeve. The bracket has the functions of lifting, supporting and adjustment of horizontal surface position; and one person can use the bracket to lift, disassemble and assemble the mutual inductor.

Description

Mutual inductor disassembly-assembly bracket in switch cabinet
Technical field:
The present invention relates to a kind of lifting implement, specifically a kind ofly be used for that instrument transformer (voltage, electric current) in the enclosed switchgear is installed, go up and down during dismounting, the disassembly-assembly bracket of support operation.
Background technology:
Enclosed switchgear is applied in the middle of 35kV, the 10kV electric pressure more and more widely; The switch cubicle high-pressure section comprises switch and auxiliary devices such as operating mechanism, disconnecting link, bus, instrument transformer, cable end, baffle plate and protector; Be enclosed in the relative narrow space, instrument transformer is a dry type, the about 180kg of weight; Be fixed in the switch cubicle liftoff 120-140cm.Interruption maintenance needs 2-3 people to bend to get into and carries out operation in the cabinet during to instrument transformer dismounting, fitting operation.
Have three bigger hidden danger aspects in the above-mentioned operation process: 1, narrow and small because of the space, the operating personnel is many, causes that working strength is big, efficient is low.2, need manpower to praise heavy equipment, be prone to fall, thus the body of hurting sb.'s feelings, hinder equipment probability bigger, have certain security risk.3, construction technology is more coarse.
Summary of the invention:
For overcoming the defective of prior art, the object of the present invention is to provide a kind of mutual inductor disassembly-assembly bracket in switch cabinet, this carriage has the function of jacking, support and horizontal plane position adjustments, and the one man operation can accomplish the work such as jacking dismounting of instrument transformer.
Technical solution problem of the present invention adopts following technical scheme:
Mutual inductor disassembly-assembly bracket in switch cabinet comprises:
One adjustable for height pedestal is connected with the load-bearing sleeve removably on said pedestal, be provided with the centripetal thrust force sliding bearing at the top of said load-bearing sleeve;
One is arranged at the involution nut on the said sliding bearing;
The one trapezoidal thread screw mandrel that cooperates with said involution nut; The top of said screw mandrel is connected with supporting plate removably; The bottom integral type of screw mandrel is connected with pilot sleeve, is provided with so that the position limiting structure that pilot sleeve only lift and not turn in the load-bearing sleeve between said pilot sleeve and the said load-bearing sleeve.
Design feature of the present invention also is:
Said pedestal is provided with four adjusting bolts as supporting leg.
Said involution nut constitutes by two lobes are involutory, and involutory with the bolt connection between two lobes, said involution nut is provided with the steering-wheel type handle.
Said load-bearing sleeve is provided with four guide blots that radially extend to the load-bearing barrel bore; Correspondingly; The outer wall of said pilot sleeve axially is provided with four road gathering sills along it, and said guide blot and said gathering sill constitute the position limiting structure that pilot sleeve only lift and not turn in the load-bearing sleeve.
Compared with present technology, beneficial effect of the present invention is embodied in:
Space in the switch cubicle of installation high-voltage mutual inductor is narrow and small, and the electric equipment of layout is many, and winding displacement is intensive, and electric clearance is had relatively high expectations.Need the instrument transformer weight of installation big, grip inconvenience, also have many lifting arrangements that are.Long-term adopt two people to lift to hold, a people is to three people's modes of operation in hole, he must removes in the cabinet facility in a large number and vacate working space for realizing this operating type.Also have the interior maximum height of cabinet only less than 1.5 meters working space, difficulty is especially put in operating personnel's space to good use, and the operation durability is relatively poor, also can weigh down the formal matter event, causes equipment and personal injury.
Utilize disassembly-assembly bracket of the present invention to install, supporting plate is used to support instrument transformer, rotates the up-down that involution nut just can be realized supporting plate, only needs a people just can accomplish whole work.Support and the jacking function owing to have, operating personnel's working strength significantly reduces, and operating efficiency greatly improves, and security reliability is guaranteed fully.
Description of drawings:
Fig. 1 is a structural representation of the present invention; Fig. 2 is the cutaway view of involution nut; Fig. 3 is the vertical view of involution nut.
Label among the figure: 1 pedestal, 2 load-bearing sleeves, 3 sliding bearings, 4 involution nuts, 5 screw mandrels, 6 supporting plates, 7 pilot sleeves, 8 regulate bolt, 9 bolts, 10 handles, 11 guide blots, 12 gathering sills.
Below pass through embodiment, and combine accompanying drawing that the present invention is described further.
Embodiment:
Embodiment: combine Fig. 1-3, the mutual inductor disassembly-assembly bracket in switch cabinet of present embodiment comprises:
One adjustable for height pedestal 1; Load-bearing sleeve 2 is connected on the pedestal 1 through bolt with the ring flange of its bottom removably; Be provided with centripetal thrust force sliding bearing 3 at the top of load-bearing sleeve; Sliding bearing is provided with rotating involution nut 4, and involution nut supports with sliding bearing and rotates, and reduces friction.
The trapezoidal thread screw mandrel 5 that cooperates with involution nut is set; The top of screw mandrel is connected with supporting plate 6 removably with ring flange and bolt; The bottom integral type of screw mandrel is connected with pilot sleeve 7, does not rotate in order to realize pilot sleeve in the load-bearing sleeve, can only go up and down, and the load-bearing sleeve is provided with four guide blots 11 that radially extend to the load-bearing barrel bore; Correspondingly; The outer wall of pilot sleeve axially is provided with four road gathering sills 12 along it, and in specifically being provided with, four guide blots along the circumferential direction are uniformly distributed with on the load-bearing sleeve; Four road gathering sills also circumferentially are uniformly distributed with on the edge at the outer wall of pilot sleeve, and guide blot 11 constitutes the position limiting structure that pilot sleeve only lift and not turn with gathering sill 12 in the load-bearing sleeve.
In specifically being provided with, pedestal 1 is provided with four adjusting bolts 8 as supporting leg, can conveniently be arranged on the rough switch cubicle base plate, and its physical dimension can guarantee that the overall operation center of gravity is positioned at a point range.
