Abstract
The utility model relates to a dual rope hoisting mechanism of a crab winch. The crab winch comprises a left winding drum and a right winding drum, and a left wire rope and a right wire rope are wound on the winding drums. A power machine drives the wire ropes to be respectively wound and disconnected after passing through a reducing mechanism. The ends of the wire ropes are respectively connected on suspension cages through fixed pulley blocks respectively installed on a headframe. The dual rope hoisting mechanism of the crab winch provided by the utility model has the advantages that the burthen of each wire rope is small, once a wire rope is broken, the other wire rope can play the protective action to avoid personal injury and damage of equipment.
Description
Affiliated technical field
The utility model relates to a kind of lift system of winch, is particularly useful for the lift system of the winch that building operation uses.
Background technology
The lift system of the winch that existing building operation is used is only to be provided with steel cable on the reel of winch, is connected to cage by fixed pulley again.Its weak point is: this single-rope hoisting mechanism, the load of steel rope is big, in case wire cable rupture will cause personal injury, equipment breaking-up accident.
The utility model content
The purpose of this utility model is the duplex type lift system that a kind of winch is provided in order to overcome above-mentioned weak point, and the load of steel rope is little, in case the steel cable fracture, another root steel rope will shield, and avoid personal injury, equipment breaking-up accident.
The technical scheme that its technical matters that solves the utility model adopts is: the reel of winch is the reel of separating about having, the steel rope on the reel be about two steel ropes independently.Engine is behind speed reduction gearing, and the steel rope that drives on the reel is rolled separately, taken apart.The end of a thread of steel rope by being installed in the fixed pulley group on the derrick, is connected on the cage again separately separately.
Effective effect of the present utility model is, uses the duplex type lift system of winch of the present utility model, and the load of steel rope is little, in case the steel cable fracture, another root steel rope will shield, and avoid personal injury, equipment breaking-up accident.
Description of drawings
Figure is the structural representation of the duplex type lift system of winch of the present utility model.1-unit power plant and speed reduction gearing among the figure, 2-cellular-type reel, 3--steel rope, 4-fixed pulley, 5-derrick, 6--cage.
Specific implementation method
The reel of winch is the cellular-type reel of separating about having (2), the steel rope (3) on the reel be about two steel ropes independently.The diameter of cellular-type reel (2) is consistent, and the thickness of steel rope (3) also is consistent.Engine is behind speed reduction gearing, and the steel rope that drives on the reel is rolled separately, taken apart.The end of a thread of steel rope (3) by being installed in the fixed pulley (4) on the derrick (5), is connected to again on the cage (6) separately separately.
Claims (2)
1, the duplex type lift system of winch, form by engine and speed reduction gearing, reel, steel rope, fixed pulley, derrick, it is characterized in that: the reel of winch is the reel of separating about having, steel rope on the reel be about two steel ropes independently, the end of a thread of steel rope by being installed in the fixed pulley group on the derrick, is connected on the cage again separately separately.
2, the duplex type lift system of winch according to claim 1 is characterized in that: the diameter of cellular-type reel (2) is consistent, and the thickness of steel rope (3) also is consistent.
