Abstract
The utility model discloses a ultra-high lift winch hoist for a hydropower station, which comprises a hoisting mechanism, wherein a coiling block of the hoisting mechanism is a duplex coiling block, namely two sides of the coiling block are symmetrical by a middle baffle as a reference, a baffle is arranged on the end portion of the coiling block, a plurality of circles of rope grooves sequentially communicated are arranged on the coiling block, each circle of the rope grooves is composed of a first broken line groove, a first straight line groove, a second broken line groove and a second straight line groove which are sequentially communicated, two guiding bosses are arranged on a side surface of the middle baffle of the coiling block and an inner side surface of an end portion baffle respectively, and one of the guiding boss on the end portion baffle and the other guiding boss on the middle baffle are symmetrical. According to the ultra-high lift winch hoist for the hydropower station, the steel wire rope guiding rope groove on the coiling block of the lifting mechanism is designed to be in a double broken line structure, and the guiding bosses are arranged on the baffles of the coiling block, thereby steel wire ropes can be winded neatly, compactly and normatively, multilayer winding is convenient to perform, and rope tangling is prevented.
Description
Technical field
The utility model relates to headstock gear, specifically is a kind of power station ultrahigh pump lift (winch hoist of lift＞60m).
Background technology
Headstock gear is one of visual plant of Hydraulic and Hydro-Power Engineering, and generating flood control, irrigation and shipping etc. are played an important role.
Headstock gear mainly is made up of transmission device, lifting mechanism, fender guard, frame and electrical control gear, and wherein lifting mechanism is made up of gear, reel and drum shaft etc. again.At present, the reel of lifting mechanism all is a double crosslinking drum usually, on reel, is provided with many circles and is communicated with, is used as the grooving that the guiding steel wire rope twines successively, and these groovings are arranged on reel in a spiral manner.When lay winding wire ropes; Grooving can correctly guide steel rope, and the ground floor steel rope neatly is wrapped on the reel, when the ground floor steel rope twines full; Preparation is climbed when carrying out second layer winding; Effective guidance structure for want of, and make can't climb the smoothly surface of ground floor steel rope of steel rope, twine at the second layer that after squeezing, just can carry out that is carrying out several circles; And; Because the guiding of spiral drum slot; Make ground floor steel rope surface form and be similar to smooth side, second layer steel rope is when twining, and the guiding of standard can't be carried out in the surface of ground floor steel rope; Cause second layer steel rope can not carry out neatly, closely, the arrangement of standard, produce the disorder cable phenomenon on the surface of ground floor steel rope.This disorder cable phenomenon can be brought a series of negative consequences, for example, causes the reel off-capacity, can't twine the residue steel rope, directly influences the headstock gear normal operation; Or frequently push between the steel rope, rub, shortened the service life of steel rope; Or the cooling diameter of steel rope on reel change, and makes two suspension centre height of gate different, and gate can be stuck in gate slot because of inclination, can't accomplish the lifting of gate, and be serious even can cause accidents such as burn-down of electric motor or wire cable rupture, and potential safety hazard is big.
In order to overcome above-mentioned disorder cable phenomenon, conventional terms of settlement is to increase drum diameter and length, and this method has directly increased the own wt and the manufacturing cost of headstock gear.
Summary of the invention
The technical purpose of the utility model is: to the deficiency of above-mentioned prior art; A kind of power station ultrahigh pump lift winch hoist is provided; The reel of this headstock gear can make be wrapped in its surperficial steel rope carry out neatly, closely, the arrangement of standard, be convenient to realize multiple wraps.
The technical purpose of the utility model realizes through following technical proposals: a kind of power station ultrahigh pump lift winch hoist; Comprise lifting mechanism; Said lifting mechanism is made up of gear, reel and drum shaft, and said reel is a double crosslinking drum, and promptly the both sides of reel are symmetrical with middle baffle plate; The end of said reel is provided with baffle plate, on reel, is provided with the grooving that many circles are communicated with successively, and each circle grooving is made up of the first broken line groove, first straight-line groove, the second broken line groove and second straight-line groove that are communicated with successively; Be respectively equipped with guide boss in the middle baffle plate side of reel and the medial surface of end baffle, and the guide boss on guide boss on the end baffle and the middle baffle plate is symmetrical.
The said first broken line groove is arranged on 0～45 ° of segmental arc of reel circumference; First straight-line groove is arranged on 45～180 ° of segmental arcs of reel circumference; The second broken line groove is arranged on 180～225 ° of segmental arcs of reel circumference, and second straight-line groove is arranged on 225～360 ° of segmental arcs of reel circumference.
Guide boss on guide boss on the said end baffle and the middle baffle plate is contrary symmetry.
The beneficial effect of the utility model is: the guiding of the steel rope on lifting mechanism reel grooving is designed to the dual slope structure; Make the steel rope surface of twining full one deck form guiding grooving to the last layer steel rope; And steel rope carries out standard guidance through the guide boss on the baffle plate and climbs after twining full one deck, steel rope can be neatly, closely, being wrapped on the reel of standard, and then formation multiple wraps; Help reducing drum diameter and length; Thereby the saving manufacturing cost alleviates the headstock gear own wt, has also stopped the disorder cable phenomenon.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the reel structure scheme drawing in the utility model.
The specific embodiment
The utility model comprises lifting mechanism, and this lifting mechanism is made up of parts such as gear, reel and drum shaft.
Referring to Fig. 1: reel 1 is a double crosslinking drum, and promptly the both sides of reel 1 are that axis is symmetrical with middle baffle plate 5.Be provided with baffle plate 3 in the end of reel 1, on reel 1, be provided with the grooving that many circles are communicated with successively, each circle grooving is made up of the first broken line groove 2-1, the first straight-line groove 2-2, the second broken line groove 2-3 and the second straight-line groove 2-4 that are communicated with successively.Wherein, The first broken line groove 2-1 is arranged on 0～45 ° of segmental arc of reel 1 circumference; The first straight-line groove 2-2 is arranged on 45～180 ° of segmental arcs of reel 1 circumference; The second broken line groove 2-3 is arranged on 180～225 ° of segmental arcs of reel 1 circumference, and the second straight-line groove 2-4 is arranged on 225～360 ° of segmental arcs of reel 1 circumference.Be respectively equipped with guide boss 6 in middle baffle plate 5 sides of reel 1 and the medial surface of end baffle 3, the guide boss on guide boss on the end baffle 3 and the middle baffle plate 5 forms contrary symmetry.
When lay winding wire ropes, the inside of reel 1 is fixed in the end of steel rope, and rope hole 4 line of centerss on the reel 1 and the radial line of reel 1 are 45 ° angle.After steel rope got into the second layer, the return angle of steel rope must be controlled in 0.25～1.5 °.
