Abstract
The present invention relates to a kind of frequency-change variable-speed winch.Including frame, reel, rotating shaft, variable-frequency motor and reductor, the reductor and variable-frequency motor are respectively and fixedly installed to the left and right ends of frame, intermeshing gear wheel and little gear are provided with the reductor, the little gear is connected with rotating shaft left end, the output axis connection that the rotating shaft right-hand member passes through shaft coupling and variable-frequency motor, the drum sheath is outside rotating shaft, the bearing being enclosed on variable-frequency motor output shaft is provided with the reel right-hand member, the splined shaft being enclosed on outside rotating shaft is provided with the reel left end, the splined shaft is meshed with gear wheel, rope is wound with the reel.The present invention is simple in construction, quick and easy for installation, by the way that reductor and variable-frequency motor are separately mounted into rotating shaft both ends, and drives spool turns by splined shaft by the gear wheel of reductor, effectively realizes frequency control, and occupy little space.
Description
Technical field
The present invention relates to a kind of hoist engine, more particularly to a kind of frequency-change variable-speed winch.
Background technology
Hoist engine, with reel lay winding wire ropes or chain lifting or the small-sized crane gear of traction, also known as winch.Hoist engine can with vertical-lift, horizontally or diagonally drag and draw weight.Hoist engine is divided into three kinds of manual hoist, electrical hoist and hydraulic winch.Now based on electrical hoist.Can be used alone, can also make lifting, build the road and the building block in the machinery such as mine hoisting, because it is simple to operate, wiring amount is big, dislocation is convenient and extensive use.The main material for applying to building, hydraulic engineering, forestry, mine, harbour etc., which is lifted or put down, to be dragged.Existing hoist engine includes reel and traction electric machine, and steel wire rope is housed on reel, and motor driven reel is gradually wrapped on reel or gradually discharged from reel around its axle center rotation, the in the process steel wire rope on reel.The motor of traditional hoist engine is common electric machine, can not realize frequency control, can not meet friction speed requirement；And the input and motor connection of traditional reductor, the output end of reductor are connected with reel, space-consuming is big, and weight is larger, installation trouble.
The content of the invention
It is quick and easy for installation it is an object of the invention to provide a kind of simple in construction for drawbacks described above, occupy little space, a kind of frequency-change variable-speed winch of frequency control can be realized.
It is for this technical solution adopted in the present invention：
Including frame, reel, rotating shaft, variable-frequency motor and reductor, the reductor and variable-frequency motor are respectively and fixedly installed to the left and right ends of frame, intermeshing gear wheel and little gear are provided with the reductor, the little gear is connected with rotating shaft left end, the output axis connection that the rotating shaft right-hand member passes through shaft coupling and variable-frequency motor, the drum sheath is outside rotating shaft, the bearing being enclosed on variable-frequency motor output shaft is provided with the reel right-hand member, the splined shaft being enclosed on outside rotating shaft is provided with the reel left end, the splined shaft is meshed with gear wheel, rope is wound with the reel.
Further, the bearing is rolling bearing.
Further, the reel is externally provided with housing, and the housing left and right ends are arranged in frame, and distance is more than rope diameter between the reel outer surface and shell inner surface, less than 2 times rope diameters.
Further, the frame lower end is provided with base, and the base is provided with mounting hole.
It is an advantage of the invention that：
The present invention is simple in construction, quick and easy for installation, by the way that reductor and variable-frequency motor are separately mounted into rotating shaft both ends, and drives spool turns by splined shaft by the gear wheel of reductor, effectively realizes frequency control, and occupy little space.
