Description

Power transformation equipment overhauling stand

Technical field

The present invention relates to a kind of power transformation equipment overhauling stand.

Background technology

At present, to the maintenance of open side type converting equipment, all be to overhaul by artificial the climbing on the high converting equipment of height, not only labour intensity is big, and relatively more dangerous.A kind of simple in structure, control easily the staff given rise near the converting equipment device, up to also not occurring at present.

Summary of the invention

The technical problem to be solved in the present invention is at above-mentioned deficiency, provide a kind of simple in structure, control power transformation equipment overhauling stand easily.

In order to solve the problems of the technologies described above, the invention provides a kind of power transformation equipment overhauling stand of following structure, comprise the pillar that base and Duo Gen arrange side by side, back one pillar is slidingly connected on the adjacent last pillar successively, first pillar is fixed on the base, is connected with workbench on the last root pillar; Power set are housed in the base, on the output shaft of power set drive sprocket is housed, the upper end of first pillar is rotatably connected to driven sprocket, be set with chain on drive sprocket and the driven sprocket, the lower end part that is fixed in second pillar behind the driven sprocket is walked around in the upper end of chain, and the lower end part that also is fixed in second pillar behind the drive sprocket is walked around in the lower end of chain; Except that first, last two pillars, the upper end of all the other pillars all is rotatably connected to support wheel; Except that last root pillar, the upper end of all the other pillars all affixed flexibility lift parts, be fixed in after the other end that lifts parts on the last pillar walks around support wheel on the adjacent back pillar, the bottom of adjacent with this back one a pillar back pillar is affixed.

The power transformation equipment overhauling stand of said structure, during non-working condition, the upper surface of all pillars is concordant, during use, this inspection platform is placed the below of converting equipment, the maintainer stands on the workbench, start power set then, power set drive drive sprocket and drive the chain rotation, chain drives second pillar and rises along first pillar slip, second pillar rises and drives the support wheel rising that connects thereon, the rising of support wheel heads on and lifts parts and make and lift the length of parts in the support wheel both sides and change, promptly be positioned at a section of support wheel front side and lift the parts lengthening, one section of rear side lifts parts and shortens, and one section of rear side lifts the 3rd pillar that result that parts shorten causes being slidingly connected on second pillar and rises along second pillar; The principle that drives the 3rd pillar rising with second pillar is identical, the 3rd pillar drives the 4th pillar when rising and rises, the 4th pillar drives the 5th pillar and rises when rising, the rest may be inferred, and the principle of the rising of back pillars such as the six roots of sensation, the 7th is same as described above.When workbench rises to desired height, stop power set and get final product.After maintenance finishes, start power set and make it counter-rotating, the pillar return that all have been risen.

Be not difficult to find out by above-mentioned, the present invention includes be set up in parallel and be slidingly connected successively together many pillars and power set, chain sprocket transmission mechanisms and lift limited parts such as parts, forward and backward by power set just can realize the rising of back one pillar along last pillar, thus the present invention have simple in structure, control advantage easily.

In order to prevent that second pillar from rising or when dropping to extreme position, the power set overwork, the two ends up and down of described first pillar and second pillar respectively are connected with stopping means.

Above-mentioned stopping means is to be connected first travel switch on the pillar and to be connected second guide vane end stop on the pillar.

The described parts that lift are chain or steel wire rope.

For more secure when used, be connected with the bondage device on the first pillar, utilize the bondage device to be strapped in above-mentioned inspection platform on the support column of converting equipment.

Move for convenience, base is provided with road wheel.
