The large hoisting device is often subjected to the situation that the position of the large hoisting device deviates from the goods during the hoisting process, so that the goods cannot be hoisted, and the position of the large hoisting device is troublesome to adjust. Therefore, the utility model provides the lifting device capable of adjusting the position of the upper frame. The operating principle of the hoisting device is as follows:
the micro-motion trolley 3 is positioned on a track, the track is arranged along the direction vertical to the axis of the winding drum, and the micro-motion trolley 3 can move on the track. When the jiggle trolley 3 moves towards the first winding drum 1, the third steel wire rope 18 and the fourth steel wire rope 19 drive the upper frame to move towards the first winding drum 1 under the traction of the jiggle trolley 3; when the jiggle trolley 3 moves towards the second winding drum 2, the first steel wire rope 16 and the second steel wire rope 17 drive the upper frame to move towards the second winding drum 2 under the traction of the jiggle trolley 3.
The first movable pulley frame 10 and the second movable pulley frame 11 can move along the direction of the winding drum relative to the upper frame, and when the first movable pulley frame 10 and the second movable pulley frame 11 move in the same direction, for example, when the first movable pulley frame 10 and the second movable pulley frame 11 move towards the first fixed pulley 6 and the third fixed pulley 8, the upper frame can move towards the second fixed pulley 7 and the fourth fixed pulley 9; or when the first movable pulley frame 10 and the second movable pulley frame 11 move towards the second fixed pulley 7 and the fourth fixed pulley 9, the upper frame moves towards the first fixed pulley 6 and the third fixed pulley 8; when the first movable pulley yoke 10 and the second movable pulley yoke 11 move in opposite directions, for example, the first movable pulley yoke 10 moves toward the first fixed pulley 6 and the second movable pulley yoke 11 moves toward the fourth fixed pulley 9, and the upper frame rotates accordingly.
The first winding drum 1 and the second winding drum 2 are controlled to rotate through a driving device, and when the first winding drum 1 and the second winding drum 2 rotate in the same direction, the steel wire rope drives the upper frame to ascend or descend; when the first reel 1 and the second reel 2 rotate in opposite directions, the wire rope on one reel extends and the wire rope on the other reel shortens, for example, when the wire rope on the first reel 1 extends and the wire rope on the second reel 2 shortens, the side of the upper frame corresponding to the second reel 2 is raised and the side corresponding to the first reel 1 is lowered.
Further, as shown in fig. 1, the body includes a support plate 24, a hanging claw 25. The four fixed pulleys and the two movable pulley carriages are arranged on the supporting plate 24; the hanging claws 25 are attached to the bottom of the support plate 24.

Furthermore, the two movable pulleys on the movable pulley frame are self-locked through an even number of open gears, and the number of teeth of the open gears on the first movable pulley frame 10 is the same as that of the open gears on the second movable pulley frame 11.
Under the condition of not arranging the open gear, even if the winding drum and the driving push rod 28 do not run, the upper frame can swing in the axial direction of the winding drum due to external force factors such as wind power, impact and the like, and at the moment, two movable pulleys of the movable pulley frame rotate in the same direction; when even number of open gears are arranged, for example, a pair of mutually meshed open gears are arranged, and the directions of rotation of the pair of mutually meshed open gears are opposite, so that the pair of open gears can prevent the two movable pulleys from rotating in the same direction, and the steel wire rope is twitched and rubbed in the movable pulleys and the fixed pulleys, so that the shaking of the upper frame is prevented, and the shaking prevention performance of the upper frame is improved. In addition, in the normal lifting process, the steering directions of the two movable pulleys of the movable pulley frame are always opposite, so that the open gear does not influence the normal operation of the movable pulleys.
Furthermore, a rope groove is formed on the surface of the winding drum, and the steel wire rope is wound in the rope groove.
The steel wire rope is wound in the rope groove, so that the steel wire rope can be prevented from deviating.
Further, the number of the jiggle trolleys 3 can be two or four, and the specific structure is shown in the following two specific embodiments:
