When shield, operator only also need to only need to inspect periodically in visual examination raising driving unit, the maintenance of wirerope,
Greatly improve the reliability of drive system and the personal safety of operation maintenance personal.
Detailed description of the invention
Fig. 1 is the lifting mechanism structural schematic diagram of embodiment in the utility model.
In figure, 1 is raising driving unit, and 2 be raising transmission system, and 3 be lifting mechanism, and 4 be crane, and 5 have been
Heavy-duty machine trolley, 6 be fixed pulley A, and 7 be fixed pulley B, and 8 be fixed pulley C, and 10 be fixed pulley D, and 11 be fixed pulley E, and 12 be fixed pulley
F, 14 be fixed pulley G, and 15 be fixed pulley H, and 9 be movable pulley M, and 13 be movable pulley N.
Specific embodiment
Embodiment in reference to the accompanying drawing is described further the embodiments of the present invention.
As shown in Figure 1, a kind of traction separate type drives crane hoisting mechanism transmission system, including crane 4, rise
Heavy-duty machine trolley 5, raising driving unit 1 are provided with monkey 5 on crane 4, have been provided on monkey 5
Mechanism 3 is risen, lifting mechanism 3 connects monkey 5 and raising driving unit 1, raising driving unit by raising transmission system 2
1 is arranged in the outside of crane 4；Raising transmission system 2 includes several pulleys and wirerope.
Raising transmission system 2 is provided with fixed pulley in the outside of crane 4, and it is fixed to be provided on crane 4
Pulley is provided with fixed pulley on monkey 5, and movable pulley is provided on lifting mechanism 3, and wirerope sequentially passes through cunning
Wheel, one end of wirerope connect raising driving unit 1, and other end ground connection is fixed.
Further, one end of wirerope is arranged on raising driving unit 1, and wirerope, which sequentially passes through, to be arranged in crane
Fixed pulley A6 outside cart 4, the fixed pulley B7 on crane 4, the fixed pulley C8 on monkey 5, lifting mechanism 3
On movable pulley M9, the fixed pulley D10 on monkey 5, the fixed pulley E11 on crane 4, on monkey 5
Fixed pulley F12, the movable pulley N13 on lifting mechanism 3, the fixed pulley G14 on monkey 5 determines on crane 4
The end of pulley H15, wirerope are fixedly connected on the ground.
Further, wirerope is a whole continuous wirerope.
Further, raising driving unit 1 is made of driving motor and driving reel, and driving motor has positive and negative rotation function
