[0043] Example 2:

[0044] Based on Example 1, in order to further improve the installation efficiency of the lower cover plate of the steel composite support, an adjustment structure is provided on the support frame 1;

[0045] As a preferred embodiment, the adjustment structure includes a hydraulic cylinder 302 arranged on the support frame 1, which is used to drive the lower cover plate for installation;

[0046] In a preferred embodiment, the adjustment structure further includes: a rotating block 301, rotatably connected to the middle of the upper end of the support frame 1, and a hydraulic cylinder 302 fixedly connected to the upper end of the rotating block 301 for supporting the hydraulic cylinder 302; a gear 305, fixedly arranged at the lower end of the rotating block 301 for driving the rotating block 301 to rotate; a spur gear 304, meshingly connected to the gear 305 for driving the gear 305 to rotate; and a motor 303, fixedly arranged on the upper surface of the upper end of the support frame 1, with its output end fixedly arranged on the spur gear 304 for driving the spur gear 304 to rotate.

[0049] Example 3:

[0050] Based on Example 2, in order to further improve the installation efficiency of the lower cover plate of the steel composite support, a clamping mechanism is provided on the support frame 1;

[0051] In a preferred embodiment, the clamping mechanism includes a clamping plate 403 arranged on the support frame 1 for fixing the installed lower cover plate;

[0052] In a preferred embodiment, the clamping mechanism further includes: a support plate 401, fixedly disposed on the output end of hydraulic cylinder 302, and clamping plate 403 slidably connected to the support plate 401 for supporting clamping plate 403; a hydraulic cylinder 402, with its tail end fixedly disposed on the support plate 401 and its output end fixedly disposed on clamping plate 403 for driving clamping plate 403 to slide on the support plate 401; and clamping plate 404, fixedly disposed on the lower surface of the support plate 401 on the side away from clamping plate 403 for cooperating with clamping plate 403 to fix and install the lower cover plate.

[0053] In a preferred embodiment, the second clamp 404 is L-shaped and the first clamp 403 is L-shaped.

[0054] Working Principle: In use, firstly, with the assistance of hoisting machinery and workers, the support frame 1 is placed on the steel crossbeam. Then, motor 201 is turned on, driving the threaded rod 202 to rotate on the support frame 1. The threaded rod 202, through two sets of reverse threads, drives the fixing plate 203 and fixing plate 204 to slide opposite each other on the support frame 1 and the limiting groove 205. When the fixing plates 203 and 204 are in contact with the steel crossbeam on both sides, the device is fixed, thereby improving the overall stability during the installation of the lower cover plate. To ensure stable construction safety, the lower cover plate is placed horizontally on top of the steel beam. Hydraulic cylinder 302 is then activated, causing support plate 401 to descend. When clamping plates 404 and 403 descend to both sides of the cover plate, hydraulic cylinder 302 is deactivated. Hydraulic cylinder 402 is then activated, causing clamping plate 403 to slide towards clamping plate 404 on support plate 401. The lower cover plate is then secured when clamping plates 404 and 403 are in contact with both sides. The hydraulic cylinder 302 is then activated in reverse, causing the lower cover plate on the support plate 401 to rise. When the lower cover plate leaves the surface of the steel profile, the hydraulic cylinder 302 is deactivated. Then, the motor 303 is activated, driving the spur gear 304 to rotate. The spur gear 304 drives the gear disc 305 to rotate, which in turn drives the rotating block 301 to rotate on the support frame 1. The rotating block 301 drives the hydraulic cylinder 302 to rotate, which in turn drives the lower cover plate on the support plate 401 to rotate. The hydraulic cylinder 302 deactivates the hydraulic cylinder 302 when the lower cover plate has rotated to 90 degrees. Turn off motor 2 (303), then turn on hydraulic cylinder 1 (302) to move the lower cover plate downwards. When the lower cover plate descends to below the steel section, turn off hydraulic cylinder 1 (302). Then turn on motor 2 (303) in the opposite direction to rotate the lower cover plate 90 degrees. Then turn off motor 2 (303) and turn on hydraulic cylinder 1 (302) to move the lower cover plate upwards to fit against the lower surface of the steel section. Then, the workers can fix the lower cover plate to the steel section beam with bolts and nuts. This not only reduces the physical strength of the workers when installing the lower cover plate, but also greatly improves the installation efficiency.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
