Abstract
The invention discloses a crane trolley, which relates to the technical field of crane machinery. The crane trolley comprises a trolley frame, wherein travelling wheels are arranged at the bottom of the trolley frame; an operating motor and an elevating motor are arranged on the trolley frame; the operating motor is connected with a speed reducer to drive the travelling wheels to move; a winding drum is arranged on the trolley frame in a position on one side of the elevating motor; the winding drum is connected with an elevating speed reducer; the elevating speed reducer and the elevating motor are connected with each other through a coupling and a transmission shaft; a fixed pulley block is arranged on the transmission shaft; the fixed pulley block is connected with a hoisting hook through a steel wire; and the elevating speed reducer is provided with a brake. The crane trolley has the advantages of large hoisting weight, small size, wide application range and safety and reliability in running.
Description
Technical field
The present invention relates to a kind of hoisting crane, relate in particular to a kind of lifting dolly that is used for the crane loading goods.
Background technology
At present, crane in bridge type is widely used in indoor and outdoor warehouse, factory building, harbour and open-air yard etc. and locates.Crane in bridge type is a kind of crane span structure type hoisting crane that crane span structure moves on aerial conveyor, claims overhead traveling crane again.The crane span structure of crane in bridge type vertically moves along being laid on the track of both sides on overhead; Crane carriage laterally moves along the track that is laid on the crane span structure; Constitute the operating range of a rectangle, just can make full use of the space handling material below the crane span structure, do not receive the obstruction of wayside equipment.
As everyone knows; The lifting dolly is the vitals of crane in bridge type; It is used for lifting power to whole hoisting crane being provided; Its design-calculated quality is directly determining the safe in operation and the hoisting weight of hoisting crane, and there is the shortcoming that hoisting weight is little, volume is big and poor for applicability in the lifting dolly of traditional crane in bridge type.
Summary of the invention
The object of the present invention is to provide a kind of crane loading dolly, it has the advantages that hoisting weight is big, volume is little, applied widely and safe and reliable to operation, to solve the problem that the crane loading dolly exists in the prior art.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of crane loading dolly, it comprises trolley frame, road wheel is installed in the bottom of said trolley frame; Wherein, be furnished with service meter on the said trolley frame and hoist electrical motor, said service meter connects the reductor ground-engaging wheel and moves; Side in the electrical motor that hoists on the said trolley frame is provided with reel; Said reel connects the speed reduction gearing that hoists, and said device rises speed reduction gearing and is connected with transmission shaft through coupler between the electrical motor with hoisting, and the dead sheave group is set on the said transmission shaft; Said dead sheave group is connected with the lifting suspension hook through steel rope, and the said speed reduction gearing that hoists is provided with drg.
Especially, energy disperser is all installed in the bottom of said trolley frame and both sides.
Especially, railing is installed in the both sides of said trolley frame.
Especially, a side of said trolley frame is installed lead frame.
Beneficial effect of the present invention is that compared with prior art said crane loading dolly has the advantage that hoisting weight is big, volume is little, range of use is wide and safe and reliable to operation.

The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through the specific embodiment.
See also Fig. 1 to shown in Figure 2, Fig. 1 is the lateral plan of the crane loading dolly that provides of the specific embodiment of the invention 1; Fig. 2 is the birds-eye view of the crane loading dolly that provides of the specific embodiment of the invention 1.
In the present embodiment, a kind of crane loading dolly comprises trolley frame 1, and road wheel is installed in the bottom of said trolley frame 1; Said road wheel comprises driving wheel 2 and flower wheel 3; And be furnished with service meter 4 on the said trolley frame 1 and hoist electrical motor 5, said service meter 4 connects operation reductor 6 and drives driving wheel 2 rotations, moves thereby drive whole trolley frame 1; Side in the electrical motor 5 that hoists on the said trolley frame 1 is provided with reel 7; Said reel 7 connects the reductor 8 that hoists, and the said reductor 8 that hoists is connected with transmission shaft 10 through coupler 9 between the electrical motor 5 with hoisting, and on the said transmission shaft 10 dead sheave group 11 is set; Said dead sheave group 11 is connected with lifting suspension hook 12 through steel rope, and the said reductor 8 that hoists is provided with drg 13.
Above embodiment has just set forth groundwork of the present invention and characteristic; The present invention is not limited by above-mentioned example; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various variations and change, and these variations and change all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
