Abstract
Hydroelectric power plant of the present utility model manual opening-closing machine special tool, uniform four screws on the outer of handwheel, with the action bars that is threaded in each screw; There is central plate the centre of handwheel, has reinforcing rib between outer and central plate, the transmission axis hole that the center of central plate has, size identical with headstock gear tip shapes to mate.Owing to increasing the arm of force, the strength of rotating drive shaft is increased greatly, make manual operation headstock gear realize save time, laborsaving, quick, headstock gear can be operated like a cork, two people can also operate simultaneously, increase work efficiency.And structure is simple, easy to operate, instrument can dismounting arbitrarily, easy to carry, occupies little space, easily takes care of.
Description
Technical field
The utility model belongs to hydroelectric power plant's manual opening-closing machine special tool.
Background technology
In hydroelectric power plant, particularly in medium and small-scale water and electricity factory, all have sand trap, each sand trap is provided with headstock gear.The keying of headstock gear generally all uses electric operating, but is not having the place of condition electricity consumption, can only adopt manual opening-closing.In order to solve the plant issue adopting manual opening-closing, the manufacturer of headstock gear can supply the handle supporting with manual opening-closing machine.But because the lifting capacity of the headstock gear of these sand traps is mostly all more than 5 tons, employment opens and closes operation manually, wastes time and energy, and efficiency is low.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of can hydroelectric power plant's manual opening-closing machine special tool of opening and closing of time saving and energy saving operation headstock gear.
The utility model solves the problems of the technologies described above with following technical scheme: uniform four screws on the outer of handwheel, with the action bars that is threaded in each screw; There is central plate the centre of handwheel, has reinforcing rib between outer and central plate, the transmission axis hole that the center of central plate has, size identical with headstock gear tip shapes to mate.
The outer of handwheel is made up of angle steel.
Hydroelectric power plant of the present utility model manual opening-closing machine special tool, owing to increasing the arm of force, makes the strength of rotating drive shaft greatly increase, make manual operation headstock gear realize save time, laborsaving, quick, headstock gear can be operated like a cork, two people can also operate simultaneously, increase work efficiency.And structure is simple, easy to operate, instrument can dismounting arbitrarily, easy to carry, occupies little space, easily takes care of.
Accompanying drawing explanation
Fig. 1 is hydroelectric power plant of the present utility model manual opening-closing machine special tool structural representation.
Detailed description of the invention
Hydroelectric power plant of the present utility model manual opening-closing machine special tool, uniform 4 screws 3 on the outer of handwheel 5, with the action bars 2 that is threaded in each screw; There is central plate 6 centre of handwheel 5, has reinforcing rib 4 between outer and central plate, the transmission axis hole 1 that the center of central plate has, size identical with headstock gear tip shapes to mate.The outer of handwheel can be made up of angle steel.
During use, first the transmission axis hole 1 at two handwheel centers is aimed at respectively the two ends of headstock gear power transmission shaft, by handwheel sleeve on headstock gear power transmission shaft, again four of special tool action bars 2 are screwed into respectively four screws 3 on handwheel outer, after tightening, namely available hand-tight action bars 2 of catching starts turn power transmission shaft, opening or closing of operation headstock gear.
