Description
Technical field
The utility model relates to the tower crane field, especially a kind of rope guide of tower crane hoist rope.
Background technology
Existing tower crane; (horizontal throw as between hoist rope reel and the back row's rope pulley axle is too little because the design of lifting mechanism rope guide is unreasonable; Be generally about 1.0m), the row who does not therefore the solve lifting mechanism well problem of restricting causes the hoist rope ordering of tower crane comparatively disorderly; Steel rope extruding mutually makes it rough sledding such as easy fracture of wire, scratch, distortion, distortion occur, causes steel rope to scrap in advance.This has not only brought economic loss to the user, and more serious is because the damage of steel rope possibly buried potential safety hazard.
The disorderly reason of steel rope ordering: when steel rope involved on reel or rolls out, there were an angle in the line of deflection sheave and reel rope stretching point and the vertical direction of spool axis, are called elevation angle.Elevation angle makes steel rope in row's rope process, except one perpendicular to the spool axis direction, steel rope is involved in or rolls out the effective pulling force, also have a horizontal force that is parallel to the spool axis direction.This horizontal force will act on the steel rope on the reel and the steel rope of waiting to be involved in or rolling out between, make between the steel rope and push, the row who the influences steel rope effect of restricting.This rope stretching angle is big more, and horizontal force is big more, and is big more to the row of the steel rope influence of restricting.In addition, this horizontal force also can act on deflection sheave, and steel rope meeting grazing pulley notch causes steel rope scratch or notch damage even takes off groove.
Summary of the invention

Summary of the invention
The utility model technical matters to be solved provides a kind of rope guide of tower crane hoist rope; Guarantee steel rope marshalling on reel; Alleviate steel rope extruding each other; Reduce its wearing and tearing, fracture of wire degree, prolong the service life of steel rope, can not get rid of to greatest extent simultaneously because of row's rope does not freely cause steel rope and jump out the risk that limit, reel two ends flange brings.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of rope guide of tower crane hoist rope; Comprise the hoist rope reel; The hoist rope reel and the two couples of back rows that the are parallel to each other seat of restricting keeps at a certain distance away on the top boom of the second joint equilibrium arm that is fixedly mounted on tower crane; Be fixed on tower crane second the joint equilibrium arm top boom on pulley bracket form by two vertical rods with two vertical rods, one end pivotally attached digonal link; Hoist rope reel and back row's rope seat are positioned between two vertical rods and the digonal link, and the place of being articulated and connected, top of pulley bracket is provided with fixed pulley, and the sheave shaft of back row's rope seat is provided with movable pulley.
Back row's rope seat is by forming through bearing pin bonded assembly U type ears panel seat and connecting panel, and the other end of connecting panel is provided with pin hole and a plurality of bolt hole.
The pin hole of connecting panel is provided with position-limited lever, and there is sheave shaft the end of connecting panel through bolted connection.
Horizontal throw between hoist rope reel and the sheave shaft is 6.5m ± 0.2m.
Owing to receive the restriction of tower machine equilibrium arm length, structure, cat head leading sheave, back deflection sheave, hoisting drum distance each other can not be provided with very greatly, if do not carry out the transformation of structure aspects, elevation angle is inevitable.Solve above-mentioned contradiction, the one, under the situation that the equilibrium arm arrangement condition allows, the distance between hoist rope reel and deflection sheave should be tried one's best greatly, makes elevation angle smaller as far as possible; The 2nd, deflection sheave is designed to traveling sheave, make it make axially reciprocating can be with the involving in or roll out of steel cable the time, further reduce elevation angle.
The rope guide of the tower crane hoist rope that the utility model provides, owing to adopt hoist rope reel, back row's rope seat and pulley bracket to match, on the row's rope seat of back, movable pulley being installed is deflection sheave; Under the situation that tower crane equilibrium arm arrangement condition allows, strengthened the horizontal throw between cable drum and deflection sheave, reduced the rope stretching angle; Make it make axially reciprocating can be with the involving in or roll out of steel cable the time; Also further reduce the rope stretching angle, therefore guaranteed steel rope marshalling on reel, alleviate steel rope extruding each other; Reduce its degree of wear; Prolong the life-span of steel rope, can not get rid of to greatest extent on the other hand because of row's rope does not freely cause steel rope and jump out the risk that limit, reel two ends flange brings, so just reduce the possibility that steel rope is scrapped; Thereby practiced thrift productive costs greatly, and improved equipment, safety of persons.
