Abstract
The utility model relates to a pulley structure of a heavy-duty truck of a tower crane. The pulley structure comprises a rack (1), pulleys (2), cross beams (3) and idler wheels (4) and is bilaterally symmetrical, the side surfaces of the rack are fixedly connected with each other through the cross beams, the pulleys are distributed on the outer sides of the cross beams, respectively, the idler wheels are arranged in the rack through steel wires of the pulleys, and the idler wheels and the pulleys are arranged in a linear manner. The pulley structure has the beneficial effects that the weight of the structure is not increased, the lifting performance of the tower crane is not influenced, and the pulley structure facilitates processing and machining and is small in welding deformation; the twisting risk during lifting of a steel wire rope can be greatly reduced by increasing the size of front and back clearances of the pulleys, and the lifting safety performance of the whole crane can be promoted; the idler wheels on the inner side of the rack can play a role in eliminating wear caused by collision between the loosened lifting steel wire rope and a trolley so as to achieve the purpose of prolonging the service life of the lifting steel wire rope.
Description
Technical field
The utility model relates to a kind of tower machine bogie pulley structure.
Background technology
In passing through the tower machine of loading trolley luffing, loading trolley main structure form has triangle and quadrangle, although the loading trolley of triangular structure form is lightweight, version is simple, but in process of production, dolly welding deformation is large especially, easily cause four angles of dolly not in an orbit plane, not steady while in use causing dolly four rolling unbalance stress, carriage walking, there is potential safety hazard.And the loading trolley of triangular structure form has caused that to be installed to the fore-and-aft cearance of the pulley on vehicle structure less, when loading trolley and suspension hook are used in conjunction with, easily cause hoist rope to beat strand, there is potential safety hazard.Although the easily production and processing of quadrilateral structure loading trolley, welding deformation are little, vehicle structure weight is large, and pulley fore-and-aft cearance is less, also easily when being used in conjunction with suspension hook, causes hoist rope to beat strand, has potential safety hazard; If during the fore-and-aft cearance of the pulley on increase vehicle structure, vehicle structure will further increase, and directly affect the lifting performance of complete machine.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of tower machine bogie pulley structure, alleviate structural weight, tower machine lifting performance improves, easily production and processing, welding deformation is little, and increases pulley installation fore-and-aft cearance size, can greatly reduce the risk that hoist rope is beaten strand, the safety performance while having promoted complete machine lift heavy.
To achieve these goals, the utility model is achieved through the following technical solutions: a kind of tower machine bogie pulley structure, comprise frame, pulley, crossbeam and third wheel, the machine forms symmetrical shape, frame side is fixedly connected with by crossbeam, pulley is arranged in crossbeam outside, and third wheel is arranged in frame by the steel wire of pulley, and third wheel and pulley " one " word arranges.
Described pulley is sister block.
Described third wheel is single-sheaved block.
The beneficial effects of the utility model are: this structural weight is lighter, by adopting novel quadrangle side, middle with two crossbeams connections, structure is optimized more, this just makes the loading trolley of this version lighter than quadrangle dolly weight, welding deformation is little, easily production and processing, owing to adopting side and crossbeam connection mode, dolly welding deformation is little, easily production and processing, be convenient to fast, batch manufacturing efficiently, the spacing of front and back pulley is large, reduced the risk that hoist rope disturbs, because the pulley on dolly is placed on the outside of two crossbeams, spacing before and after having increased between lifting pulley, thereby increased through the non-parallelism between the lifting pulley hoist rope of both sides, reduced the risk that hoist rope disturbs, the installation of third wheel has improved the steel wire service life and eliminating safe hidden trouble of hoisting, and can avoid hoist rope to contact with loading trolley, cause the steel wire wear that hoists, thereby improve the service life of hoist rope, potential safety hazard while eliminating tower machine lift heavy.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is birds-eye view of the present utility model.
In figure: 1, frame, 2, pulley, 3, crossbeam, 4, third wheel.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As depicted in figs. 1 and 2, this tower machine bogie pulley structure, comprise frame 1, pulley 2, crossbeam 3 and third wheel 4, the machine forms symmetrical shape, frame 1 side is fixedly connected with by crossbeam 3, pulley 2 is arranged in crossbeam 3 outsides, increased the spacing between left and right sides pulley 2, increased through the non-parallelism between the hoist rope of left and right sides pulley 2, thereby improved the situation that the steel wire that hoists disturbs, third wheel 4 is arranged in frame 1 by the steel wire of pulley 2, avoid running into loading trolley when hoist rope is lax in lift heavy thing not and cause hoist rope wearing and tearing, third wheel 4 and pulley 2 " one " words arrange, pulley 2 is positioned over frame 1 outside, make the larger distance of acquisition between pulley 2, thereby greatly reduce the risk that hoist rope disturbs.
Claims (3)
1. a tower machine bogie pulley structure, comprise frame (1), pulley (2), crossbeam (3) and third wheel (4), it is characterized in that, the machine forms symmetrical shape, frame (1) side is fixedly connected with by crossbeam (3), pulley (2) is arranged in crossbeam (3) outside, and third wheel (4) is arranged in frame (1) by the steel wire of pulley (2), and third wheel (4) and pulley (2) " " word arrange.
2. tower machine bogie pulley structure according to claim 1, is characterized in that, described pulley (2) is sister block.
3. tower machine bogie pulley structure according to claim 1, is characterized in that, described third wheel (4) is single-sheaved block.
