Abstract
The utility model relates to a fence type winding drum lifting mechanism of a single-arm frame seat type crane, which is widely used for the single-arm frame seat type crane with extremely high lifting height. The fence type winding drum lifting mechanism comprises a fence type winding drum (5), bearing seats (4), a driving mechanism (3), a speed reducer (2), an electric motor (1) and a brake (6), wherein two ends of the fence type winding drum (5) are respectively installed on the two bearing seats (4) through two shaft heads (7), one of the two shaft heads (7) is connected with the speed reducer (2) through the driving mechanism (3), the speed reducer (2) is connected with the electric motor (1), and the brake (6) is installed on the other shaft head. The fence type winding drum lifting mechanism can well solve the problem of lifting a winding drum for rope storage and also reduce the size of a turntable and a propeller strut so as to be convenient for the overall design of the crane.
Description
(1) technical field
The utility model relates to a kind of single armed frame high pedestal jib crane hedge formula reel lifting mechanism.Be widely used in the king-sized single armed frame of lifting altitude high pedestal jib crane.The technical field that belongs to elevator machinery.
(2) background technology
Along with China's shipbuilding and the fast development of shiprepair industry, for big elevating height, single armed frame high pedestal jib crane demand is increasing significantly.The crane hoisting bottom-to-top-height of the type is generally in the 60-100m scope, and the reel of its lifting mechanism generally adopts the individual layer steel rope to twine reel (seeing accompanying drawing 1 and Fig. 2).Because steel rope is wrapped on the reel, there is maximum constraints its drift angle, so the same rotating disk of winding of single layer reel length, Shears size have very big relation.If reel length is longer, will causes the rotating disk size to become big, Shears height increase, thereby bring adverse influence, and then cause the increase of manufacturing, installation, traffic cost to rubber tyre gantry crane design.In addition, because the winding of single layer reel is spiral drum slot, the winding of single layer reel is if carry out multiple wraps, and the steel rope contact surface is little when carrying out multiple wraps, and steel rope is stressed bad, and reduce service life.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of hoisting drum storage rope problem that both can well solve is provided, can reduce the size of rotating disk, Shears again, thereby be convenient to the single armed frame high pedestal jib crane hedge formula reel lifting mechanism of the general design of hoisting crane.
The purpose of this utility model is achieved in that a kind of single armed frame high pedestal jib crane hedge formula reel lifting mechanism, comprise hedge formula reel, bearing seat, transmission device, retarder, electrical motor and drg, described hedge formula reel two ends are installed in respectively on the diaxon bearing by two spindle noses, in described two spindle noses, wherein a spindle nose links to each other with retarder by transmission device, retarder links to each other with electrical motor, and on another spindle nose drg is installed.
The beneficial effects of the utility model are:
1, the hedge formula reel that adopts of the utility model can multiple wraps, and oad is little, and is in light weight, is convenient to rubber tyre gantry crane design, and the rotating disk inner space is big, is convenient to internal unit and arranges and maintenance of equipment, has reduced manufacturing, installation, traffic cost.Cost-cutting that can be bigger.
2, the hedge formula reel that adopts of the utility model is exactly can multiple wraps with the difference of winding of single layer reel maximum, its grooving is that one section linear pattern grooving and one section spiral drum slot are formed, contact surface is big between steel rope when multiple wraps, and steel rope is stressed good, long service life.
In sum, hedge formula reel is applied to the big elevating height crane hoisting mechanism both can well solve hoisting drum storage rope problem, can reduce the size of rotating disk, Shears again, thereby be convenient to the general design of hoisting crane.
