Abstract
The invention provides a double-beam bridge crane which is unlikely to be limited by the height of a plant. The double-beam bridge crane comprises a trolley, a coiling block and a steel wire, wherein the coiling block is arranged on a left beam end and is connected with a motor; the steel wire is wound with a first plane spiral coil and a second spiral coil on the coiling block on the left beam end, and the winding directions of the first plane spiral coil and the second spiral coil are the same; a first trolley wheel and a second trolley wheel are fixed on one side, on a main beam, of the trolley, and a fixed pulley is fixed on one side, on another main beam, of the trolley; a horizontal fixed pulley is fixed on a right beam end; and after forming the first plane spiral coil, the steel wire sequentially bypasses the first trolley wheel, a first movable pulley, the fixed pulley, a second movable pulley, the second trolley pulley and the horizontal fixed pulley and finally winds the coiling block to form the second plane spiral coil. According to the crane, the original operation mechanisms and hoisting mechanism are not used, so that the trolley is lightened and lowered, then the complete machine is lowered, and thus a trolley frame is relatively light and convenient.
Description
Technical field
The present invention relates to crane, be specifically related to a kind of double girder overhead crane.
Background technology
General-purpose overhead crane because of its bearing capacity large, the advantages such as good stability are widely used in various types of workshops, factory building and warehouse. Its lifting mechanism is generally all arranged on the top of running trolley, and part factory building, because ignoring the restriction of headroom height, in the time of erection crane, has run into the difficult problem that crane small cart frame and workshop steel structure are interfered, and cannot meet the needs of installation; Install if reduce the orbit altitude of double girder crane, larger to the lifting altitude loss of used double girder crane, give and use enterprise to bring greater inconvenience.
Carry out mill construction change difficulty large, workload is heavy, therefore, by the travelling mechanism of dolly and lifting mechanism are moved on to end carriage place, reduces complete machine height, makes trolley frame lighter.
Summary of the invention
The invention provides a kind of double girder overhead crane that is not subject to factory building height restriction.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of crane that can reduce whole height, comprise dolly 1, reel 2, reel 2 is arranged on left beam-ends, reel 2 connects motor, also comprise steel wire 3, steel wire 3 is wound with the first planar spiral winding 4 on the reel 2 of left beam-ends, the second planar spiral winding 5, the first planar spiral winding 4 is identical with the second planar spiral winding 5 winding directions, the side of dolly 1 on girder is fixed with the first wheel 6, the second wheel 7, the side of dolly 1 on another girder is fixed with fixed pulley 8, right beam-ends is fixed with horizontal fixed pulley 9, steel wire 3 is walked around the first wheel 6 after being the first planar spiral winding 4, walk around again the first movable pulley 10, walk around again fixed pulley 8, walk around again the second movable pulley 11, walk around again the second wheel 7, walk around again horizontal fixed pulley 9, finally on reel 2, be coiled into the second planar spiral winding 5, the first movable pulley 10 overlaps with the axial line of the second movable pulley 11, and the first movable pulley 10 and second movable pulley 11 is rotatable is fixed on axial line.
By rotating drum left, make the first planar spiral winding and the second planar spiral winding tighten up steel wire, the function of wire of the first planar spiral winding, in the first wheel, makes the first wheel want to roll, steel wire upwards shrinks simultaneously, and the first movable pulley is moved upward; The steel wire of the second planar spiral winding tightens up, and makes horizontal fixed pulley rotation, and the steel wire on the second wheel tightens up to the right, and the second movable pulley is moved upward, and make the hook of crane drive weight to move upward, and while dolly is to left movement.
The present invention can not use original travelling mechanism and lifting mechanism, and the dolly weight alleviating reduces little height and also just reduces complete machine height, makes trolley frame lighter.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is steel wire winding schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
A kind of crane that can reduce whole height, comprise dolly (1), reel (2), described reel (2) is arranged on left beam-ends, described reel (2) connects motor, also comprise steel wire (3), it is characterized in that, described steel wire (3) is wound with the first planar spiral winding (4) and the second planar spiral winding (5) on described reel (2), described the first planar spiral winding (4) is identical with described the second planar spiral winding (5) winding direction, the side of described dolly (1) on girder is fixed with the first wheel (6) and the second wheel (7), the side of described dolly (1) on another girder is fixed with fixed pulley (8), right beam-ends is fixed with horizontal fixed pulley (9), described steel wire (3) is around walking around described the first wheel (6) for after described the first planar spiral winding (4), walk around again the first movable pulley (10), walk around again described fixed pulley (8), walk around again the second movable pulley (11), walk around again described the second wheel (7), walk around again described horizontal fixed pulley (9), finally on described reel (2), be coiled into described the second planar spiral winding (5), described the first movable pulley (10) overlaps with the axial line of described the second movable pulley (11), and described the first movable pulley (10) is fixed on its axial line with described the second movable pulley (11) is rotatable.
By rotating drum left, make the first planar spiral winding and the second planar spiral winding tighten up steel wire, the function of wire of the first planar spiral winding, in the first wheel, makes the first wheel want to roll, steel wire upwards shrinks simultaneously, and the first movable pulley is moved upward; The steel wire of the second planar spiral winding tightens up, and makes horizontal fixed pulley rotation, and the steel wire on the second wheel tightens up to the right, and the second movable pulley is moved upward, and make the hook of crane drive weight to move upward, and while dolly is to left movement.
The present invention can not use original travelling mechanism and lifting mechanism, and the dolly weight alleviating reduces little height and also just reduces complete machine height, makes trolley frame lighter.
