The first worm wheel 52 is connected to a position close to the center of the first bidirectional screw 3. The first worm 51 is rotatably connected in the transmission groove 2 along the width direction of the positioning transmission groove 2. The first worm 51 and the first worm wheel 52 are meshed and connected. The first worm 51 is connected to a turning handle 5.

[0019] The second power assembly includes a second bidirectional screw 11, a second worm 53 and a second worm wheel 54.

Both ends of the second bidirectional screw 11 are respectively connected to the second movable beam 12 through ball sliders.

The second worm 53 and the second worm wheel 54 are meshed and connected. The second worm 53 is connected to a turning handle 5.

[0020] A rubber pad 10 is connected to one side of the U-shaped clamping plate 9 close to the first moving beam 4 .

[0021] The vertical projection of the guide plate 8 is J-shaped.

[0022] A groove 13 is provided in the vertical direction on one side of the guide plate 8 close to the positioning beam plate 1 , and rubber guide rollers 6 are arranged in an array in the groove 13 .

[0023] A reinforcing plate 7 is provided on one side of the second moving beam 12 close to the guide plate 8 , and the reinforcing plate 7 connects the guide plate 8 and the second moving beam 12 .

[0024] Principle and operation process The present invention realizes the driving of the first moving beam 4 and the second moving beam 12 through the first power assembly and the second power assembly. For the first power assembly, the turning handle 5 on the first worm 51 is rotated. Due to the meshing of the first worm 51 and the first worm wheel 52, the first worm wheel 52 rotates, driving the first bidirectional screw 3 connected thereto to rotate. The two ends of the first bidirectional screw 3 are connected to the first moving beam 4 through ball sliders. According to the characteristics of the bidirectional screw, its rotation can make the first moving beam 4 move toward or away from each other in the length direction of the positioning beam plate 1. Similarly, in the second power assembly, the turning handle 5 of the second worm 53 is rotated, and the second moving beam 12 is driven to move in the transmission groove 2 along the length direction of the positioning beam plate 1 through the transmission of the second worm 53, the second worm wheel 54, and the second bidirectional screw 11; the guide plate 8 is vertically projected into a J shape. When the composite plate is tightened and the composite plate is started to be hoisted, the guide plate 8 first contacts the composite beam. Due to the J-shaped design of the guide plate 8, even if there is a certain position deviation at the beginning of contact, the guide plate 8 can slide along the edge of the composite beam and guide the entire device to accurately clamp on both sides of the composite beam. Even if there is a certain deviation in the initial stage, it will be automatically corrected as it is lowered. The rubber guide rollers 6 arranged in an array in the groove 13 on the side of the guide plate 8 close to the positioning beam plate 1 can reduce the friction between the guide plate 8 and the composite plate, further ensuring the smoothness of the guide; the U-shaped clamp at the end of the first movable beam 4 is used to clamp the composite plate. When the first movable beam 4 moves under the drive of the first power assembly, the U-shaped clamp moves accordingly. The rubber pad 10 connected to the U-shaped clamp close to the side of the first movable beam 4 plays a buffering role when clamping the composite plate, which can not only protect the surface of the composite plate from damage, but also increase the friction force to ensure the stability of the clamping. At the same time, the bidirectional synchronous telescopic characteristics of the first power assembly and the second power assembly ensure that the composite plate is always in the center position of the positioning beam plate 1 during the clamping process, which is conducive to subsequent accurate installation. The reinforcing plate 7 disposed on the side of the second moving beam 12 close to the guide plate 8 firmly connects the guide plate 8 to the second moving beam 12. During the use of the device, especially when the guide plate 8 frequently contacts and collides with the composite plate, the reinforcing plate 7 can effectively prevent the guide plate 8 from deforming or breaking, thereby increasing the overall service life of the device. In addition, the meshing structure of the worm and the worm wheel in the first power assembly and the second power assembly utilizes the self-locking property of the worm and worm wheel, which can limit the self-rotation of the worm, thereby ensuring that after clamping the composite plate, the clamping state of the device is stable, and the first moving beam 4 and the second moving beam 12 will not be accidentally moved due to external forces or other factors.

[0025] When in use, first adjust the position of the first moving beam 4 by turning the handle 5 of the first power assembly so that the spacing between the U-shaped clamps on both sides is slightly larger than the width of the composite board to be installed. At the same time, turn the handle 5 of the second power assembly to adjust the position of the second moving beam 12 so that the spacing between the guide plate 8 is larger than the distance between the two U-shaped clamps 9, then lift the device to a position close to the composite board, place the composite board between the two U-shaped clamps 9, turn the first worm 51, clamp the composite board, and then start the lifting device to lift the composite board and slowly lower it to a position close to the installation positioning device. In the process of lowering the composite board, the guide plate 8 first contacts the composite beams on both sides. Due to the J-shaped design of the guide plate 8 and the action of the rubber guide roller 6, even if the position of the composite board is not completely accurate during the lowering process, the guide plate 8 can slide along the edge of the composite beam, and the guiding device gradually aligns with the composite beam, so that the device is accurately stuck on both sides of the composite beam. In this process, the operator needs to observe the contact between the guide plate 8 and the composite beam to ensure that the guiding process proceeds smoothly. After the guide plate 8 completely guides the device to align with the composite beam, continue to lower the composite plate until the composite plate is stably placed on the composite beam. During the placement process, due to the self-locking property of the worm and worm gear, the device can stably clamp the composite plate during the entire installation process without loosening or shifting. After the composite plate is installed, reversely rotate the handle 5 of the first power assembly to move the first movable beam 4 away from each other, loosening the clamping of the U-shaped clamp on the composite plate. At the same time, reversely rotate the handle 5 of the second power assembly to return the second movable beam 12 to its initial position. Then, lift the installation positioning device away to prepare for the next composite plate installation operation.

Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
