Abstract
The utility model belongs to the technical field of cranes and particularly relates to a hoisting mechanism. The compact high-lift hoisting mechanism comprises a motor (1), a speed reducer (3), a winding drum device (4), steel wire ropes and a lifting hook (11). The winding drum device (4) is double combined winding drums, rope guide baffles (14) are arranged at two ends of the double combined winding drums to enable the steep wire ropes to be wound in two layers, one winding drum (7) is a left-toward rope race, and the other winding drum (8) is a right-toward rope race. The two steel wire ropes are of a non-rotating structure, one steel wire rope is a left-winding steel wire rope (10) on the double combined winding drums, the other steel wire rope is a right-winding steel wire rope (9) on the double combined winding drums, and the steel wire ropes directly round across a pulley (12) on the lifting hook (11) and are connected reliably in the position above the pulley (12) through a rope coupler (13) to enable the pulley (12) to be only lifted and lowered along with the steel wire ropes but not to rotate. The compact high-lift hoisting mechanism not only effectively avoids the rope disorder and rope seizing phenomena which easily happen when the lift is ultra-high, controls the length of the hoisting winding drums quite well, and meets the requirements of the type of crane under special operation conditions.
Description
Technical field
The utility model belongs to the hoisting crane technical field, particularly a kind of lifting mechanism.
Background technology
At present, the power station outlet vertical shaft following handling characteristics of lifting mechanism ubiquity of maintenance bridge machine: the 1. because weight of the article that overhaul is lighter, so hoisting capacity less (generally below 6 tons); Hang and get article because its suspension hook will go deep into silo bottom below hundreds of rice, therefore lifting altitude large (often more than 200 meters) especially.2. due to the lift of superelevation, so the regularity that hoist rope is arranged during multiple wraps on reel requires very high, and in hook lifting process, forbid to occur the phenomenon of " stinging rope " (being that steel rope kinks together mutually) between each steel rope aloft.3. outlet vertical shaft hole diameter is little, so the length dimension of hoisting drum is required to do very littlely, under guarantee, rope is not interfered with the borehole wall.In crane hoisting mechanism commonly used, there is no a kind of type to above-mentioned operating mode particularly suitable now.
The utility model content
The purpose of this utility model is: a kind of lifting mechanism that is applicable to power station outlet vertical shaft maintenance hoisting crane is provided.
The technical solution of the utility model is: the high winding lifting mechanism of a kind of compact comprises: electrical motor, retarder, roll device, steel rope, suspension hook; It is characterized in that:
Described roll device is that two ends are provided with the double crosslinking drum that the conductor rope baffle plate makes the double-deck winding of steel rope, and one of them reel is the left-hand grooving, and another reel is the dextrad grooving; Its effective total length is less than vertical shaft well head diameter, and described double crosslinking drum diameter satisfies the requirement of high elevator being held the rope amount;
Described steel rope is two not rotational structure steel ropes, and a left-handed dextrorotation, directly walk around the pulley on described suspension hook on described double crosslinking drum, and reliably connects with socket in described pulley top position; Described pulley is not only rotated with described steel rope lifting.
Another technical scheme is: the high winding lifting mechanism of compact described above is characterized in that: the high speed shaft of described retarder is provided with plate disc brake; Described roll device one end is provided with brake disc and sure brake.
When the utility model has not only effectively been avoided the superelevation elevator, incident " disorder cable " reaches " stinging rope " phenomenon, and controlled well the length dimension of hoisting drum, satisfied the special operation condition needs of the type hoisting crane.
