Abstract
The utility model provides a power driving device for a lifting hook, relates to a driving device for lifting appliances, and solves the problems that at present, a device for driving the lifting hook is complex in structure and high in expenses, and the lifting hook has the risk of falling down due to an unstable structure of the device. Two standard pulley sets are fixedly disposed on the upper end face of a lifting beam and are symmetrically arranged along a central axis of the lifting beam. A tail shaft of the lifting hook sequentially penetrates through a bearing nut and the upper end face of the lifting beam from the lower end face of the lifting beam and is disposed outside the lifting beam. The tail shaft of the lifting hook is rotatably connected with the lifting beam. A large driving gear is arranged on the tail shaft of the lifting hook. The large driving gear is meshed with a small driving gear. The small driving gear is disposed on an output shaft of a planetary reducer of a cycloid pin wheel. An anti-disengaging plug pin is disposed inside the lifting beam. The bearing nut is fixedly connected with the tail shaft of the lifting hook through the anti-disengaging plug pin. The power driving device for the lifting hook is applied to large-scale cranes.
Description
Technical field
The utility model relates to a kind of driving device of suspender.
Background technology
At present, double-hung crane in bridge type hanging beam hook self drive not in the lifting industry, the lifting object can't be realized fast rotation, influences double-hung crane in bridge type range of use.For realizing this function, suspension hook drives through gear transmission revolution strut member and realizes that this type suspension hook adopts suspension type to install in the lifting industry.
Because gear transmission revolution strut member drives the suspension hook rotation, complex structure, expense is high, and suspension hook is connected with the revolution strut member through bolt, structural instability, there is the danger of falling in suspension hook.
The utility model content
The purpose of the utility model provides a kind of power drive that is used for suspension hook, and is complicated with the apparatus structure that solves present driving suspension hook, expense is high and structural instability causes suspension hook to exist falling dangerous problem.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: said device comprises hanging beam, cycloidal pinwheel planetary gear speed reducer, drive pinion, transmission big gear wheel, load-bearing nut, suspension hook, anticreep latch and two standard pulley groups; Be fixed with two standard pulley groups on the upper surface of hanging beam; Two standard pulley groups are symmetrical set along the central axis of hanging beam; The tailing axle of suspension hook passes load-bearing nut and hanging beam successively from the lower surface of hanging beam upper surface is located at the outside of hanging beam, and the tailing axle of suspension hook and hanging beam be rotationally connected, and the transmission big gear wheel is housed on the tailing axle of suspension hook; Transmission big gear wheel and drive pinion engagement; Drive pinion is contained on the output shaft of cycloidal pinwheel planetary gear speed reducer, and the anticreep latch is located at the inside of hanging beam, and the load-bearing nut is affixed through the tailing axle of anticreep latch and suspension hook
The utlity model has following beneficial effect: the utility model is simple in structure, expense is low and Stability Analysis of Structures, and suspension hook load-bearing nut is fixed through the tailing axle of anticreep latch and suspension hook in the structure, prevents that suspension hook from falling.
Description of drawings
Fig. 1 is the integral structure scheme drawing of the utility model.
The specific embodiment
The specific embodiment one: combine Fig. 1 that this embodiment is described; The device of this embodiment comprises hanging beam 1, cycloidal pinwheel planetary gear speed reducer 3, drive pinion 4, transmission big gear wheel 5, load-bearing nut 6, suspension hook 8, anticreep latch 9 and two standard pulley groups 2; Be fixed with two standard pulley groups 2 on the upper surface of hanging beam 1; Two standard pulley groups 2 are symmetrical set along the central axis of hanging beam 1; The tailing axle of suspension hook 8 passes load-bearing nut 6 and hanging beam 1 successively from the lower surface of hanging beam 1 upper surface is located at the outside of hanging beam 1, and the tailing axle of suspension hook 8 and hanging beam 1 be rotationally connected, and transmission big gear wheel 5 is housed on the tailing axle of suspension hook 8; Transmission big gear wheel 5 and drive pinion 4 engagements; Drive pinion 4 is contained on the output shaft of cycloidal pinwheel planetary gear speed reducer 3, anticreep latch 9 be located at hanging beam 1 inside and, load-bearing nut 6 is affixed with the tailing axle of suspension hook 8 through anticreep latch 9
Hanging beam 1 structure confirms that according to playing heavy lift hanging beam 1 is connected with crane in bridge type through standard pulley group 2 (lifting industry standard part), and the structure of standard pulley group 2 is confirmed by load.Simultaneously can change standard pulley group 2 into shackle structure according to different needs.
The specific embodiment two: combine Fig. 1 that this embodiment is described; The device of this embodiment also comprises the clutch shaft bearing 7 and second bearing 10; The tailing axle of suspension hook 8 is rotationally connected through the lower surface of clutch shaft bearing 7 with hanging beam 1, and the tailing axle of suspension hook 8 is rotationally connected through the upper surface of second bearing 10 with hanging beam 1.This structure transmission effect stability.Other composition and annexation are identical with the specific embodiment one.
The specific embodiment three: combine Fig. 1 that this embodiment is described, the tailing axle length L of the suspension hook 8 of this embodiment is 486mm, and this structure can make on the tailing axle of suspension hook 8 transmission gear is housed, and satisfies integrally-built needs.Other composition and annexation are identical with the specific embodiment one or two.
Principle of work: hanging beam 1 is connected with crane in bridge type through standard pulley group 2, and the output shaft of cycloidal pinwheel planetary gear speed reducer 3 drives drive pinion 4 and rotates, thereby drive pinion 4 rotates with the tailing axle that 5 engagements of transmission big gear wheel drive suspension hook 8.
