Abstract
The utility model relates to a special lifting tool for replacing a disconnecting switch mechanism box inner gear case. The special lifting tool for replacing the disconnecting switch mechanism box inner gear case comprises a horizontal beam, a screw and two driftbolt bolts. The screw is vertically installed in the center of the horizontal beam in a meshed mode. The two driftbolt bolts are respectively and vertically installed on the horizontal beam and are respectively arranged on the left and right sides of the screw. The special lifting tool for replacing the disconnecting switch mechanism box inner gear case is designed as a tool lifting through the screw rotating according to a structure feature that a gear case is fixed in a mechanism box through four opposite-angle bolts of the top of the mechanism box. According to the special lifting tool for replacing the disconnecting switch mechanism box inner gear case, the gear case can be disassembled and assembled safely and quickly without disassembly of a disconnecting switch vertical transmission bar and the mechanism box. The special lifting tool for replacing the disconnecting switch mechanism box inner gear case plays roles of shortening power off maintenance time, improving equipment available coefficient and working safety, lightening labor intensity of a maintaining person, and ensuring safe production and grid safe operation.
Description
Technical field
The utility model relates to the lifting tool in electric power overhaul and the area of maintenance, especially a kind of Special lifting instrument of changing isolating switch mechanism case inner gear box.
Background technology
Tianjin Power Company overhauling company jurisdiction 220kV and the old equipment of above substation are more, particularly more at the old type GW6/7 type disconnector of dress, because at that time manufacturing process and material selection are relatively poor, in recent years, this type isolating switch mechanism case (CJ2 type) inner gear box ironcasting cracking phenomena happens occasionally, and causes the equipment interruption maintenance.
Have a following difficult problem in changing the gearcase process: a) gearcase is the total journey of transmission that motor and gear form, and quality own is 30kg approximately.B) narrow space in the mechanism case, in the inner dismounting of mechanism case, Work tool is difficult for using, and manpower can't be control.
Based on above factor, the programme of work of in the past changing isolating switch mechanism case (CJ2 type) inner gear box has two kinds.Scheme one: mechanism case is separated with the lever of writing a biography, and the disassembly mechanism case keeps flat, and needs at least two people to carry away gearcase.Scheme two: do not tear the lever of writing a biography open, at mechanism case bottom bolster wood, and the adapted jack, gearcase is pulled down.There are many defectives such as large and interruption maintenance time of operating difficulties, labor strength is long in above-mentioned two schemes in implementation process.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of Special lifting instrument of reasonable in design, simple in structure, easy to operate, the replacing isolating switch mechanism case inner gear box that can improve overhaul efficiency is provided.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of Special lifting instrument of changing isolating switch mechanism case inner gear box, it is characterized in that: comprise horizontal beam, screw rod and two drift bolt bolts, screw rod vertically meshes the center that is installed in horizontal beam, two drift bolt bolts all vertically are installed on the horizontal beam, and these two drift bolt bolts lay respectively at the left and right sides of screw rod.
And the bottom of described screw rod is by chassis of the coaxial installation of jackscrew, and a spanner is installed on the top of screw rod, and the length of screw rod is 450mm.
And the length of described two drift bolt bolts is 360mm, and the bottom of these two drift bolt bolts all is shaped with the screw thread of M16*40.
And, make two mounting holes on the described horizontal beam, these two mounting holes are symmetricly set in the left and right sides of screw rod, and two drift bolt bolts vertically are inserted into respectively in separately the mounting hole, and the distance between these two drift bolt bolt axle center is 220mm.
And described horizontal beam is cross-arm.
Advantage of the present utility model and beneficial effect are:
1, this Special lifting instrument comprises horizontal beam and is installed in screw rod and drift bolt bolt on the horizontal beam, get final product the lifting of pinion box by the rotation of screw rod, therefore use this instrument in the situation that do not unload disconnector write a biography lever and mechanism case, can change or safeguard gearcase.
2, because this Special lifting instrument is easy to use laborsaving, therefore can increase work efficiency, shorten power off time, reduce have a power failure to around the impact that brings of user, improve power supply reliability.
3, this Special lifting tool construction is simple, easy to manufacture, cost is low, raw MAT'L is easy to obtain, and is highly suitable in the electric system and promotes the use of.
4, the utility model is a kind of simple in structure, design is ingenious, it is laborsaving to use, low cost of manufacture, practical being exclusively used in are changed isolating switch mechanism case inner gear box lifting tool, this instrument is a kind ofly by four at mechanism case top corner bolt to be fixed in constructional feature in the mechanism case for gearcase, and design pass through the instrument that bolt rotary carries out lifting.This instrument of use can be in the situation that do not dismantle disconnector write a biography lever and mechanism case, safe and efficient dismounting gearcase, play the interruption maintenance time that shortens, improve the equipment availability coefficient, improve work safety, alleviate the labour intensity of service personnel, the effect that ensures safety in production and guarantee electric power netting safe running.

The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of Special lifting instrument of changing isolating switch mechanism case inner gear box comprises horizontal beam 3, screw rod 2 and two drift bolt bolts 4, and the horizontal beam in the present embodiment is cross-arm.Screw rod vertically engagement is installed in the made tapped bore in horizontal beam center, the length of screw rod is 450mm, a polygonal spanner 7 (being generally hexagonal) is made in the upper end of screw rod, and a spanner 1 is installed on this spanner, and the bottom of screw rod is by chassis 6 of jackscrew 5 coaxial installations.
Make two mounting holes on the horizontal beam, these two mounting holes are symmetricly set in the left and right sides of screw rod, two drift bolt bolts vertically are inserted into respectively in separately the mounting hole, therefore two drift bolt bolts lay respectively at the left and right sides of screw rod, the length of two drift bolt bolts is 360mm in the present embodiment, the bottom of two drift bolt bolts all is shaped with the screw thread of M16*40, and the distance between two drift bolt bolt axle center is 220mm.
Principle of work of the present utility model is:
Opening mechanism box top fixed gear wheel box to corner bolt, special tool and gearcase are threaded connection, open a pair of to corner bolt in addition, this moment, the weight of gearcase was all born by lifting tool, the rotating special tool middle screw rod, the liftable gearcase is after gearcase drops to the position, special tool is separated with gearcase, and gearcase namely separates with mechanism case.
