Referring to fig. 1, a lifting mechanism for a single-girder crane for reducing sway includes a case 2 for connecting with a crane girder 1. The box body 2 is rotatably connected with a plurality of idler wheels 24 through a connecting plate, and the idler wheels 24 are abutted against the upper end of the crane beam 1, so that the box body 2 can move along the length direction of the crane beam 1. A steel wire rope 21 is connected in the box body 1, the steel wire rope 21 is connected with a movable pulley 22, and a weight hook 23 is fixedly connected with the movable pulley 22. The box body 2 is also connected with a telescopic sleeve group 3, and the telescopic sleeve group 3 is sleeved on the steel wire rope 21.
Referring to fig. 2, a winding drum 20 is rotatably connected in the box body 2, a steel wire rope 21 is wound on the winding drum 20, and one end of the steel wire rope 21, which is far away from the winding drum 20, penetrates through a side wall of the box body 2 and is wound on a movable pulley 22 and then is fixedly connected with the box body 2.
The rollers 24 are rotated so that the entire box body 2 can be slid along the lifting beam 1. The reel 20 is driven to rotate, the reel 20 takes up and takes down the steel wire rope 21, the height positions of the movable pulley 22 and the weight hook 23 are changed, and the process of lifting the weight, conveying the weight to a designated position and putting down the weight is realized. The telescopic sleeve group 3 sleeved on the steel wire rope 21 limits the displacement of the steel wire rope 21 in the horizontal direction, and reduces the shaking of the steel wire rope 21.
Referring to fig. 2, the telescopic sleeve groups 3 are provided in two sets, and the two telescopic sleeve groups 3 are correspondingly provided on the wire ropes 21 at both sides of the movable sheave 22. The telescopic sleeve group 3 includes a first sleeve 31, a second sleeve 32, and a third sleeve 33. The upper end of the first sleeve 31 is fixedly connected with the box body 2. The second sleeve 32 is slidably arranged in the first sleeve 31, and the third sleeve 33 is slidably arranged outside the first sleeve 31 and the second sleeve 32. A connecting rod 332 is fixedly connected between the two third sleeves 33. The lower end of the connecting rod 332 is fixedly connected with a buffer layer 333, and the buffer layer 333 can be made of elastic rubber.
The first sleeve 31, the second sleeve 32 and the third sleeve 33 are connected in a sliding manner, so that the length of the whole telescopic sleeve group 3 can be changed. Since the exposed length of the wire rope 21 is changed when the heavy object is lifted, the length of the telescopic sleeve group 3 can be changed along with the change of the exposed length of the wire rope 21, and the displacement of the exposed wire rope 21 in the horizontal direction is limited. The connecting rod 332 reduces the self-shaking of the telescopic sleeve group 3 when the telescopic sleeve group is extended to a large length, and the buffer layer 333 reduces the collision or the damage of parts caused by the collision between the connecting rod 332 and the movable pulley 22 when the winding drum 20 is wound.
Referring to fig. 3, oil grooves 30 are formed in the inner walls of the first sleeve 31 and the third sleeve 33.
Lubricating oil is added to the first sleeve 31 and the third sleeve 33 through the oil groove 30, so that the telescopic sliding of the telescopic sleeve group 3 is smoother.
Referring to fig. 3, the first sleeve 31 has a first limiting ring 311 fixed at a lower end thereof, the second sleeve 32 has a second limiting ring 321 fixed at an upper end thereof, a third limiting ring 322 fixed at a lower end thereof, and the third sleeve 33 has a fourth limiting ring 331 fixed at an upper end thereof.

The implementation principle of the lifting mechanism for the single-beam crane for reducing the shaking is as follows: the reel 20 is unwound, the exposed length of the wire rope 21 increases, and the weight hook 23 falls. At this time, the second sleeve 32 and the third sleeve 33 slide downward due to their own weight, so that the length of the telescopic sleeve group 3 is increased, and displacement of the exposed wire rope 21 is restricted, thereby reducing the play of the wire rope 21. The reel 20 is reeled, the exposed length of the steel wire rope 21 is reduced, the weight hook 23 rises, the movable pulley 22 abuts against the connecting rod 332, the second sleeve and the third sleeve 33 slide upwards, the length of the telescopic sleeve group 3 is reduced, and the telescopic sleeve group 3 cannot influence the lifting mechanism to lift the weight.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
