[0027] The execution component 12, including a slide block 121 slidably installed inside the chute 112, a vertical frame 122 fixedly installed at the top of the slide block 121, a limit frame 123 fixedly installed at the bottom of the slide block 121, a rope 124 penetratingly installed on the limit frame 123, and a hook 125 installed on the rope 124;

[0028] The adjusting assembly 13 includes four equally distributed winding drums 131 rotatably mounted at the bottom of the frame 111 , and the upper ends of the ropes 124 are fixed to the outer walls of the winding drums 131 .

[0029] In this embodiment, the threaded sleeve 114 is driven by rotating the handwheel 115, and the threaded sleeve 114 drives the sleeve frame 116 to rise and fall. The sleeve frame 116 drives the slider 121 through the upper support rod 117 and the lower support rod 118 in cooperation with the vertical frame 122. The slider 121 drives the hook 125 on the rope 124 to move through the limit frame 123, so that the hooks 125 in four directions can be gathered or dispersed at the same time, so as to realize the lifting of structural parts of different specifications.

[0030] Specifically, the adjustment assembly 13 further includes a positioning ring 132 fixed to the outer wall of the upper end of the winding drum 131 , and a plurality of positioning grooves 133 are formed on the outer wall of the positioning ring 132 and are distributed in equal parts.

[0031] In this embodiment, the length of the rope 124 can be retracted or extended by rotating the reel 131, thereby adjusting the distance between the hook 125 and the frame 111, so that the hook 125 can hook different positions of the structural member for lifting it.

[0032] Specifically, the adjustment assembly 13 further includes a positioning plate 134 mounted on the bottom of the frame 111 by bolts 136 , and four equally distributed positioning heads 135 fixed on the outer wall of the positioning plate 134 , and the positioning heads 135 cooperate with the positioning slots 133 .

[0033] In this embodiment, when the hook 125 on the rope 124 is stretched to an appropriate length, the positioning plate 134 is fixed by a bolt 136, and at the same time, the positioning head 135 on the positioning plate 134 is embedded in the positioning groove 133 on the positioning ring 132, limiting the rotation of the winding drum 131, thereby fixing the extended length of the rope 124.

[0034] Specifically, the actuator 12 further includes a connector 126 rotatably mounted on the lower end of the rope 124 , and the upper end of the hook 125 is threadedly mounted on the connector 126 .

[0035] In this embodiment, the hook 125 can be disassembled and assembled, so that the hook 125 of suitable specifications can be installed according to the structural parts.

[0036] Specifically, the auxiliary mechanism 1 further includes hanging rings 14 installed at the top of the four corners of the frame 111 , and the hanging rings 14 are threadedly installed on the frame 111 .

[0039] In this embodiment, the slider 121 is caused to move parallelly inside the chute 112 by the cooperation of the upper support rod 117 and the lower support rod 118.

[0040] The working principle and usage process of the present utility model are as follows: First, by rotating the handwheel 115 to drive the threaded sleeve 114, the threaded sleeve 114 drives the sleeve frame 116 to move up and down. The sleeve frame 116 drives the slider 121 through the cooperation of the upper support rod 117 and the lower support rod 118 with the vertical frame 122. The slider 121 drives the hook 125 on the rope 124 to move through the limit frame 123, so that the hooks 125 in four directions can be gathered or dispersed simultaneously, realizing the hoisting of structural members of different specifications.

[0041] Then, by rotating the rope winding drum 131, the length of the rope 124 can be wound and released, thereby adjusting the distance between the hook 125 and the frame 111. When the hook 125 on the rope 124 is stretched to an appropriate length, the positioning plate 134 is fixed by the bolt 136. At the same time, the positioning head 135 on the positioning plate 134 is embedded in the positioning groove 133 on the positioning ring 132 to limit the rotation of the rope winding drum 131, thereby fixing the extended length of the rope 124, enabling the hook 125 to hook different positions of the structural member and hoist it.

[0042] Finally, the lifting device can smoothly lift the structural member hoisted on the auxiliary mechanism 1 through the lifting rings 14 at the four corners.
