Abstract
The invention discloses a rope arrangement mechanism for a hoisting drum of a large gantry crane, which comprises a first sprocket wheel, a second sprocket wheel, a speed reducer, a universal coupling, a third sprocket wheel, a housing, a fourth sprocket wheel and movable blocks, the rotary shaft of the hoisting drum can rotate to drive the hoisting drum and the first sprocket wheel to rotate together, the first sprocket wheel transmits power to the third sprocket wheel sequentially via a drive chain, the second sprocket wheel, the speed reducer and the universal coupling, the third sprocket wheel drives the movable blocks in the housing by means of a drive chain and the forth sprocket wheel to move along the axial direction of the hoisting drum, and ensures that the movable blocks arranged in the housing can move for a drum rope slot pitch along the axial direction of the hoisting drum each time when the hoisting drum makes a rotation, and thereby a wire rope rounding the movable blocks can be accurately guided into a corresponding drum rope slot, and can be prevented from jumping out of the slot and being partially overlapped. The rope arrangement mechanism solves the problem that the wire rope can jump out of the slot or can be partially overlapped when the hoisting drum of the conventional large gantry crane carries out hoisting, prolongs the service life of the wire rope, and enhances the safety of the gantry crane in use.
Description
Technical field
The present invention relates to the hoisting drum that large-sized gantry hangs, particularly large-sized gantry is sling and is risen the rope-arranging mechanism of reel.
Background technology
The large-sized gantry rise height of slinging, hoisting drum is long, in the process of hoisting, when steel rope is wound into the other end from reel one end, job-hopping or local stratification can occur, has a strong impact on service life and gauntry crane safe in utilization of steel rope.
Summary of the invention
The purpose of this invention is to provide a kind of large-sized gantry slings and rises the rope-arranging mechanism of reel; Sling and rise reel steel rope job-hopping or local range upon range of problem in the process of hoisting to solve existing large-sized gantry, thereby prolong the service life of steel rope and improve the safety in utilization of gauntry crane.
The objective of the invention is to realize through following technical scheme:
A kind of large-sized gantry is sling and is risen the rope-arranging mechanism of reel; Comprise first sprocket wheel, second sprocket wheel, retarder, universal coupling, the 3rd sprocket wheel, support, the 4th sprocket wheel and movable pulley; Said first sprocket wheel is fixedly installed on an end of the rotating shaft of hoisting drum; Said second sprocket wheel is fixedly installed on the said input shaft of speed reducer; Said first sprocket wheel is connected through driving chain with second sprocket wheel; Said the 3rd sprocket wheel is arranged on an end of said top of the trellis through its sprocket shaft; The sprocket shaft of said the 3rd sprocket wheel is connected with the output shaft of said retarder through said universal coupling, and said the 4th sprocket wheel is arranged on the other end of said top of the trellis on the hoisting drum axis direction through its sprocket shaft, be provided with in the said support a pair of along the arrangement of hoisting drum axis direction also be linked together movable pulley; One walk around the driving chain of the 3rd sprocket wheel and the 4th sprocket wheel two ends be separately fixed on the nonrotational part of said movable pulley; On the hoisting drum axis direction, be installed with the space that supplies said movable pulley to move in the said support, the moving circle of said hoisting drum revolution, the movable pulley that is arranged in the said support moves a drum rope groove distance on the hoisting drum axis direction.
Preferably, the nonrotational part of said movable pulley is provided with roller, and said support hoisting drum axis direction is provided with and said roller corresponding guide rail.
Preferably, the nonrotational part of said movable pulley is provided with chain tensioning device.
Principle of work of the present invention is: the drive hoisting drum is rotated in the rotating shaft of hoisting drum and first sprocket wheel rotates together; First sprocket wheel is given retarder through the driving chain and second sprocket wheel with transmission of power; Retarder is given the 3rd sprocket wheel through universal coupling with transmission of power; The 3rd sprocket wheel moves on the hoisting drum axis direction through the movable pulley that driving chain and the 4th sprocket wheel drive in the support; And make the hoisting drum revolution move a circle; Be arranged on movable pulley in the said support and on the hoisting drum axis direction, move a drum rope groove distance, thereby lead the steel rope of walking around movable pulley accurately in the corresponding roller grooving, the job-hopping of avoiding steel rope is with local range upon range of.
Beneficial effect of the present invention is: compact conformation, connection and reasonable arrangement, operate steadily reliable; Slinging at large-sized gantry rises in the process that steel rope can not be job-hoped or local range upon range of on hoisting drum, thereby prolongs the service life of steel rope and improve the safety in utilization of gauntry crane.
