Abstract

The invention discloses a tool special for replacement of a transformer fan. The tool comprises steel wire ropes, two gaskets and two steel wire rope self-locking devices. The steel wire rope self-locking devices are falling prevention devices matched with the steel wire ropes. The gaskets can be arranged on the steel wire ropes in a sleeving manner. The outer diameter of the steel wire ropes is smaller than the outer diameter of fan base threaded holes in a transformer heat radiator and the outer diameter of fan base threaded holes in a transformer fan base. The tool is low in cost, convenient to operate, safe and reliable.

Description

A kind of transformer fan changes specific purpose tool
Technical field
The present invention relates to machining tools art, be specifically related to a kind of transformer fan and change specific purpose tool.
Background technology
Through investigation, the fan in the some electrical power Transformer Forced-Air Cooling System currently used is installed on bottom radiating fin of transformer, and installation site is relatively low, safeguards bringing huge potential safety hazard to maintenance repair.Current way is to carry out Maintenance and Repair after transformer power failure, is unfavorable for reliable power supply and the safe operation of equipment.
For above-mentioned deficiency, design and a kind of transformer fan of exploitation is needed to change specific purpose tool, it is possible to supply each shortcoming above-mentioned.
Summary of the invention
In order to solve the problem of above-mentioned existence, the present invention provides a kind of transformer fan to change specific purpose tool.
The present invention is to be achieved through the following technical solutions:
A kind of transformer fan changes specific purpose tool, including steel wire rope, two pads and two steel wire rope self-locking devices, described steel wire rope self-locking device is the falling proof device matched with steel wire rope, pad on a steel cord can be overlapped, the little external diameter with the fan base screwed hole on transformer radiator and transformer fan base with fan base screwed hole of external diameter of described steel wire rope sized by described pad.
Preferably, described steel wire rope self-locking device is provided with and leads mouth.
Preferably, described transformer radiator be respectively equipped with four identical fan base screwed holes of size symmetrical above and below and fan base screwed hole on the base of transformer fan.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is with low cost, easy to operate, safe and reliable.

Fig. 1 is the schematic diagram of structure of the present invention；
Fig. 2 is transformer radiator base front view of the present invention.
In figure: 1, transformer radiator；1-1, fan base screwed hole；2, transformer fan；2-1, fan base screwed hole；3, steel wire rope self-locking device；3-1, lead mouth；4, steel wire rope；5, pad.
Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings:
Such as Fig. 1, shown in Fig. 2, a kind of transformer fan changes specific purpose tool, including steel wire rope 4, two pads 5 and two steel wire rope self-locking devices 3, described steel wire rope self-locking device 3 is the falling proof device matched with steel wire rope 4, the pad on steel wire rope 4 can be enclosed within sized by described pad 5, the little external diameter with the fan base screwed hole 1-1 on transformer radiator 1 and transformer fan 2 base and fan base screwed hole 2-1 of external diameter of described steel wire rope 4, described steel wire rope self-locking device 3 is provided with leads a mouthful 3-1, described transformer radiator 1 be respectively equipped with four size symmetrical above and below identical fan base screwed hole 1-1 and fan base screwed hole 2-1 on the base of transformer fan 2.
nullOperation principle: first steel wire rope 4 is adequately inserted from leading mouthful 3-1 of steel wire rope self-locking device 3，Confirm that steel wire rope is by stuck fast，Then steel wire rope is penetrated a pad 5，When transformer fan 2 is lifted to installation site，Steel wire rope 4 is penetrated from bottom to up at fan base screwed hole 2-1，Steel wire rope 4 is the most from bottom to up through fan base screwed hole 1-1，And penetrate another one pad 5 and steel wire rope self-locking device 3 on steel wire rope 4 top，Regulation and the length of steel wire rope 4，Then fasten，Utilize same principle that another set of instrument is installed at the fan base screwed hole 1-1 and fan base screwed hole 2-1 to inclined-plane，So fan is just firmly fixed the bottom at radiator，Staff can install two other screw，After two other screw installs，The most dismountable instrument，Then screw is installed，Reach with low cost，Easy to operate、Safe and reliable effect.
The general principle of the present invention, principal character and advantage have more than been shown and described.Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; the principle that the present invention is simply described described in above-described embodiment and specification; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within scope of the claimed invention.Claimed scope is defined by appending claims and equivalent thereof.
