The utility model content
The purpose of the utility model provides a kind of large-sized gantry and slings and rise 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 purpose of the utility model realizes 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.
The principle of work of the utility model 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.
The beneficial effect of the utility model 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.
