[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 4 This embodiment provides a movable bearing frame for bridge construction, and the movable bearing frame for bridge construction includes:

[0026] A bottom plate 1, a first load-bearing plate 4 and a second load-bearing plate 6 are arranged at the top of the bottom plate 1, and a lifting adjustment component is arranged at the top of the bottom plate 1, and the lifting adjustment component is used to realize the lifting adjustment of the first load-bearing plate 4 and the second load-bearing plate 6;

[0027] A synchronous gear set, which is rotatably connected to the inside of the base plate 1 and is in transmission connection with the lifting and adjusting assembly, and is used to achieve synchronous adjustment of the lifting and adjusting assembly and improve the stability of the lifting and adjusting assembly during the lifting process;

[0028] Compared with the prior art, by setting a synchronous gear set, the synchronous rotation of each threaded rod 7 in the lifting and adjusting assembly can be achieved, thereby improving the stability of the lifting and adjusting assembly during the lifting process. By achieving smooth lifting and lowering of the lifting and adjusting assembly, the material on the upper ends of the first supporting plate 4 and the second supporting plate 6 can be prevented from falling due to excessive shaking, thereby improving the overall safety performance of the device.

[0029] See also Figure 1 , Figure 2 and Figure 4 In one embodiment, the lifting and adjusting assembly comprises:

[0030] The threaded rod 7 is rotatably connected to the inside of the bottom plate 1 and is evenly arranged around the bottom plate 1. The top of the bottom plate 1 is fixedly mounted with a support column 3. The middle of the support column 3 is provided with a rectangular groove 11, and the inner side of the support column 3 is provided with a transverse groove 12;

[0031] An adjusting column 5, wherein the adjusting column 5 is slidably connected to the inside of the rectangular groove 11 and is threadedly matched with the threaded rod 7, a second bearing plate 6 is fixedly mounted on the top end of the adjusting column 5, and a first bearing plate 4 is fixedly mounted on the bottom end of the adjusting column 5;

[0032] See also Figure 1 In one embodiment, one end of the base plate 1 located on the ground is fixedly connected to a moving wheel 2, and the moving wheel 2 is symmetrically arranged with respect to the base plate 1;

[0033] When it is necessary to use the first load plate 4 and the second load plate 6 to carry and transport materials, the materials are placed on the upper ends of the first load plate 4 and the second load plate 6 respectively, and the entire device is moved to the bridge construction position with the assistance of the moving wheels 2.

[0036] A transmission gear 10, wherein the transmission gear 10 is fixedly connected to one end of the threaded rod 7 located inside the bottom plate 1, and the adjustment gear 9 and the transmission gear 10 are meshed for transmission;

[0037] When it is necessary to supply materials to positions at different heights, the adjustment shaft 8 inside the base plate 1 is controlled to rotate, and the adjustment shaft 8 then drives the adjustment gear 9 to rotate. Due to the meshing transmission between the adjustment gear 9 and the transmission gears 10, the synchronous rotation of multiple transmission gears 10 can be achieved, and then the synchronous rotation of multiple threaded rods 7 can be achieved. Due to the threaded cooperation between the adjustment column 5 and the threaded rod 7, the rotation of the threaded rod 7 can make the adjustment column 5 slide vertically along the rectangular groove 11 in the middle of the support column 3, thereby realizing the lifting and lowering adjustment of the first load plate 4 and the second load plate 6, and transporting the material to the specified height for use by the staff.

[0039] The working principle of the utility model is:

[0040] In this embodiment, when it is necessary to use the first load plate 4 and the second load plate 6 to carry and transport materials, the materials are placed on the upper ends of the first load plate 4 and the second load plate 6 respectively, and the device is moved to the bridge construction position as a whole with the assistance of the moving wheel 2. When it is necessary to supply materials to positions at different heights, the adjustment shaft 8 inside the base plate 1 is controlled to rotate, and the adjustment shaft 8 then drives the adjustment gear 9 to rotate. Due to the meshing transmission between the adjustment gear 9 and each transmission gear 10, the synchronous rotation of multiple transmission gears 10 can be achieved, and then the synchronous rotation of multiple threaded rods 7 can be achieved. Due to the threaded cooperation between the adjustment column 5 and the threaded rod 7, the rotation of the threaded rod 7 can make the adjustment column 5 slide vertically along the rectangular groove 11 in the middle of the support column 3, thereby realizing the lifting and lowering adjustment of the first load plate 4 and the second load plate 6, and transporting the materials to the specified height for use by the staff.
