Abstract
The utility model relates to a detaching and installing dedicated tool for a brake of a water-turbine generator set. The detaching and installing dedicated tool for the brake of the water-turbine generator set comprises a steel wire rope lifting mechanism. An insertion groove and an idler wheel are arranged on the steel wire rope lifting mechanism. One ends of two parallel steel wire ropes are fixed in the steel wire rope lifting mechanism and wind the idler wheel. The other ends of the two parallel steel wire ropes suspend. A clamp is arranged between the steel wire rope lifting mechanism and the suspension ends of the steel wire ropes and of an annular structure. The two sides of the annular structure are parallel planes. At least one pulley is installed on each plane and the pulleys are connected with the steel wire ropes in a contact mode. With the structure, one ends of the steel wire ropes are connected with the steel wire rope lifting mechanism, and after the other ends of the steel wire ropes are fixed with proper fixtures, the brake which is fixed with the clamp can be supported by the steel wire ropes. The brake can be conveniently moved to the left or the right through the pulleys on the clamp by slightly exerting leftward or rightward force on the clamp.
Description
Technical field
The utility model relates to a kind of extracting tool, is specifically related to a kind of brake of hydroelectric generating set tool specially for attaching and detaching.
Background technology
Brake is hydraulic generator unit vitals, its effect has two: one, unit braking, during shutdown, for prevent unit under the slow-speed of revolution long-play with the protection thrust bearing, pass into compressed air when generating unit speed is reduced to rated speed 15%, by friction, reaches braking function; The 2nd, the top rotor: by hydraulic oil, can be by unit rotating part jack-up.Each unit brake quantity is many, and pipeline is comparatively complicated, the oil pressure during rotor of top more than 12 MPas, so the unit brake have pipeline complexity, top rotor oil pressure high, use characteristics frequently, just because of These characteristics, make brake easily damage.The brake bottom is connected with buttress, and top and rotor have 10 to 15mm gap, and single weight is in the 400kg left and right, so the brake of 400kg left and right will be split out to difficult from little gap like this.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of instrument that can facilitate the brake dismounting and install provided.
The purpose of this utility model is achieved in that
A kind of brake of hydroelectric generating set tool specially for attaching and detaching, it comprises the steel wire rope elevating mechanism, be provided with slot and roller on the steel wire rope elevating mechanism, one end of side by side two bar steel wire ropes is fixed in the steel wire rope elevating mechanism and is wrapped on roller, the other end is unsettled, between steel wire rope elevating mechanism and steel wire rope free end, is provided with fixture; Above-mentioned fixture is circulus, and the both sides of circulus are the plane be parallel to each other, and at least one pulley is installed on each plane, and pulley is connected with the steel wire rope contact.
Roller in above-mentioned steel wire rope elevating mechanism is provided with manual rocking bar.
The utility model has been obtained following technique effect:
While adopting said structure, steel wire rope one end is connected with the steel wire rope elevating mechanism, and by the other end and suitable fixture fixing after, the brake fixed with fixture can rely on steel wire rope to support, if to fixture a little application point power to the left or to the right can by the pulley on fixture, facilitate brake to move left and right on steel wire rope;
Adopt roller in the steel wire rope elevating mechanism to be provided with the structure of manual rocking bar, can be convenient for people to reach and make fixture vertical mobile purpose up and down by the folding and unfolding steel wire rope.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 and Fig. 3 are the utility model use procedure figure.
The specific embodiment
A kind of brake of hydroelectric generating set tool specially for attaching and detaching as shown in Figure 1, it comprises steel wire rope elevating mechanism 1, be provided with slot and roller on steel wire rope elevating mechanism 1, one end of side by side two bar steel wire ropes 2 is fixed in steel wire rope elevating mechanism 1 and is wrapped on roller, the other end is unsettled, between steel wire rope elevating mechanism 1 and steel wire rope free end, is provided with fixture 3; Described fixture 3 is circulus, and the both sides of circulus are the plane 4 be parallel to each other, and at least one pulley 5 is installed on each plane 4, and pulley 5 is connected with the steel wire rope contact.
Roller in described steel wire rope elevating mechanism 1 is provided with manual rocking bar, can be convenient for people to reach and make fixture vertical mobile purpose up and down by the folding and unfolding steel wire rope.
While adopting said structure, as shown in Figures 2 and 3, at first the utility model is mounted on unit, adjusting the steel wire rope elevating mechanism makes steel wire rope tighten and make brake to leave slightly bottom buttress 6, touch to the left or to the right the brake 7 fixed with fixture, just can easily brake be unloaded, adopt contrary step brake can be in place.
