A second motor 802 is fixedly connected to the placement frame 801, and the output end of the second motor 802 rotates and penetrates the inner surface of the placement frame 801. The output end of the second motor 802 is fixedly connected to a lifting threaded rod 804. The outer surface of the lifting threaded rod 804 is threadedly rotatably connected to a fixing frame 803. The bottom of the fixing frame 803 is fixedly connected to a first clamping plate 805. The inner surfaces of both sides of the placement frame 801 are respectively provided with sliding grooves 806. The outer surfaces of both sides of the first clamping plate 805 are respectively provided with sliders 811. The outer surfaces of the sliders 811 are slidably connected to the inner surfaces of the sliding grooves 806. The front surface of the placement frame 801 is fixedly connected to a third motor 810. The output end of the third motor 810 rotates and penetrates the front surface of the placement frame 801. The output end of the third motor 810 is fixedly connected to a second bidirectional threaded rod 808. The second bidirectional threaded rod 808 is rotatably connected to the placement frame 801. Second clamping plates 807 are symmetrically arranged on the outer surface of the second bidirectional threaded rod 808. The inner surfaces of the two second clamping plates 807 are both threadedly rotatably connected to the outer surfaces of the second bidirectional threaded rod 808.

[0025] The effect achieved by the entire embodiment 1 is that when the hoist is used for steel structure engineering, the crane is connected to the two lifting ears 2 through tools such as steel cables, so that the frame 1 can be lifted, and the two placement frames 801 are adjusted according to the length of the square steel to be hoisted at the construction site, and the first motor 7 is started. The output end of the first motor 7 drives the first bidirectional threaded rod 3 to rotate accordingly, and the two moving blocks 6 will respectively move toward or oppositely on the outer surfaces of the plurality of first fixed rods 5 through the connection of the two threaded blocks 4, thereby adjusting the distance between the two groups of fixed components 8. The square steel is inserted between the two placement frames 801 in turn, and the center of the square steel is kept balanced between the two placement frames 801 through the drive adjustment of the crane and the first motor 7, and the two groups of fixed components 8 are started synchronously, and the output end of the second motor 802 drives the lifting threaded rod 804 to rotate accordingly. 5 will move up and down accordingly under the action of the threaded rotation connection between the fixing frame 803 set on its top and the lifting threaded rod 804, and the two sliders 811 set on its two sides will slide in the two sliding grooves 806 respectively, so that the first clamping plate 805 will resist the top of the square steel when moving down, so that it will abut against the inner bottom surface of the placement frame 801, and the third motor 810 will be started. The output end of the third motor 810 drives the second two-way threaded rod 808 to rotate accordingly, and the two second clamping plates 807 will move towards each other to clamp and resist the front and back of the square steel. Under the cooperation of another set of fixing components 8, the two ends of the square steel will be tightly fixed in the placement frame 801, so as to prevent the square steel from shaking during the lifting process and affecting the lifting of the crane. At the same time, the time used for the fixing process of the square steel is reduced, so as to avoid occupying the precious time of the crane and improve the construction efficiency of the hoisting device for steel structure engineering.

[0026] Embodiment 2, as Figure 1-Figure 4 As shown, the inner surface of the placement frame 801 is symmetrically fixedly connected with a second fixing rod 809 near the bottom side, and the outer surfaces of the two second fixing rods 809 are slidably connected to the inner surfaces of the two second clamping plates 807. The inner surface of the placement frame 801 is provided with grooves on both sides near the bottom, and the two second clamping plates 807 are respectively located in the two grooves.

[0027] The effect achieved by the entire embodiment 2 is that, when in use, the second fixing rod 809 is symmetrically fixedly connected to one side of the inner surface of the placement frame 801 near the bottom, so that the two second clamping plates 807 are limited when moving, thereby reducing the friction with the placement frame 801 and improving the movement effect. By hiding the two second clamping plates 807 in the grooves on both sides of the placement frame 801 so that there are no protrusions on the inner surfaces of both sides of the placement frame 801, the square steel is not easy to collide with the placement frame 801 when inserted. At the same time, rubber pads are arranged on multiple clamping plates, which increases the resistance effect of multiple clamping plates on the square steel, and is highly practical.

[0028] Working principle: When the hoist is used in steel structure engineering, the crane is connected to the two lifting ears 2 through tools such as steel cables, and the frame 1 can be lifted. The two placement frames 801 are adjusted according to the length of the square steel to be hoisted at the construction site, and the first motor 7 is started. The output end of the first motor 7 drives the first bidirectional threaded rod 3 to rotate accordingly. The two moving blocks 6 will respectively move toward or oppositely on the outer surfaces of the multiple first fixed rods 5 through the connection of the two threaded blocks 4, respectively, to adjust the distance between the two sets of fixed components 8, and insert the square steel into the two placement frames in turn. The center of the square steel is kept balanced between the two placing frames 801 by driving and adjusting the crane and the first motor 7, and the two sets of fixing components 8 are started synchronously. The output end of the second motor 802 drives the lifting threaded rod 804 to rotate accordingly. The first clamping plate 805 moves up and down accordingly under the action of the threaded rotation connection between the fixing frame 803 set on its top and the lifting threaded rod 804. The two sliders 811 set on both sides of it slide in the two sliding grooves 806 respectively, so that the first clamping plate 805 moves up and down on the top of the square steel when moving down. The third motor 810 is started, and the output end of the third motor 810 drives the second bidirectional threaded rod 808 to rotate accordingly. The two second clamping plates 807 move toward each other to clamp and resist the front and back of the square steel. With the cooperation of another set of fixing components 8, the two ends of the square steel will be tightly fixed in the placement frame 801 to prevent the square steel from shaking during the lifting process, affecting the lifting of the crane, and at the same time reducing the time used for the square steel in the fixing process, avoiding occupying the precious time of the crane, and improving the efficiency of the slings used in steel structure engineering. In order to improve the construction efficiency, the second fixing rod 809 is symmetrically fixed on one side of the inner surface of the placement frame 801 near the bottom, so that the two second clamps 807 are limited when moving, the friction with the placement frame 801 is reduced, and the movement effect is improved. By hiding the two second clamps 807 in the grooves on both sides of the placement frame 801, there are no protrusions on the inner surfaces of both sides of the placement frame 801, so that the square steel is not easy to collide with the placement frame 801 when inserted. At the same time, rubber pads are arranged on multiple clamps to increase the resistance effect of multiple clamps to the square steel, which is highly practical.
