[0013] 1. When inspecting a bridge, it is necessary to send maintenance personnel to a high place through a bridge safety construction platform to inspect the bridge. When transporting materials from the bottom of the construction platform to the top, first put the materials on the hook to fix them, and then select the rotating rod to be rotated according to the weight of the material. When the material is lighter, by rotating the rotating rod on one side of the large gear, the rotating rod can drive the handle to rotate, and the handle can drive the large gear to rotate, so that the large gear and the gear shaft rotate.

When cleaning the debris generated during the construction in the connecting frame, a group of movable plates are pushed to move, and the movable plates will move in the debris discharge trough. When the movable plates move a distance exceeding half of their own width, under the action of gravity, the movable plates will rotate to one side through the inclined debris discharge trough. At this time, the inclined movable plates will discharge the debris on the upper surface through the debris discharge trough to complete the cleaning of the connecting frame. The above operations can facilitate the cleaning of the bridge safety construction platform. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1-Figure 4 The utility model provides a technical solution: a safe bridge construction platform for transporting materials, comprising: a base 1 and a movable plate 16, a hydraulic rod 2 is installed on the top of the base 1, a lifting frame 3 is fixedly connected to one side of the hydraulic rod 2, one side of the top of the lifting frame 3 is slidably connected to a connecting frame 5 through a sliding rod, the other side of the top of the lifting frame 3 is fixedly connected to the connecting frame 5, the bottom of the connecting frame 5 is connected to a multi-section electric telescopic rod 4, and the bottom of the multi-section electric telescopic rod 4 is fixedly connected to the base 1,

[0022] Two groups of connecting plates 6 are welded and fixed on the top of the connecting frame 5, and one side of the two groups of connecting plates 6 is movably connected with a handle 7 through a bearing. A sliding groove matching the rotating rod 8 is opened inside the handle 7, and the rotating rod 8 is slidably connected to the sliding groove. A limiting groove 9 matching the rotating rod 8 is opened on one side of the connecting plate 6. A gear shaft 11 is movably connected between the two groups of connecting plates 6 through a bearing. A small gear 10 is meshed and connected to one side of the gear shaft 11. A winding drum 13 is fixedly connected to the middle part of the gear shaft 11, and a large gear 12 is meshed and connected to the other side of the gear shaft 11; a winding rope 14 is wound around the outer side of the winding drum 13, and a hook 15 is fixedly connected to one end of the winding rope 14; one side of the large gear 12 and the small gear 10 are both fixedly connected to the handle 7, and a plurality of groups of limiting grooves 9 are provided, and the plurality of groups of limiting grooves 9 are distributed at equal angles with respect to the rotation axis of the handle 7. The small gear 10 and the gear shaft 11 constitute a meshing transmission structure, and the rotating rod 8 constitutes a sliding structure with the handle 7 through a slider.

[0023] In specific implementation, when inspecting a bridge, it is necessary to send the inspectors to a high place through the bridge safety construction platform to inspect the bridge. When transporting the materials at the bottom of the construction platform to the top, first put the materials on the hook 15 for fixing, and then select the rotating rod 8 to be rotated according to the weight of the materials. When the materials are light, by rotating the rotating rod 8 on one side of the large gear 12, the rotating rod 8 can drive the handle 7 to rotate, and the handle 7 can drive the large gear 12 to rotate, so that the large gear 12 and the gear shaft 11 rotate. The number of teeth on the axle 11 is smaller than that of the large gear 12. The teeth of the two are relatively large when they are meshed, so the gear shaft 11 can be driven to rotate quickly. The gear shaft 11 can drive the winding rope 14 to rotate quickly. The winding rope 14 can pull the hook 15 and the material to move up quickly. When it moves up to the connecting frame 5, the rotating rod 8 can be pushed to move, so that the rotating rod 8 is engaged with the limiting groove 9 on one side of the connecting plate 6. At this time, the handle 7 will not be able to rotate, so that the winding drum 13 cannot rotate either, and the material on the hook 15 can be taken;

[0024] When heavier materials need to be transported, the pinion 10 is driven to rotate by rotating the rotating rod 8, and the pinion 10 can mesh with the gear shaft 11. Since the number of teeth on the gear shaft 11 is greater than that of the pinion 10, the tooth ratio when the two are meshing is relatively small, and the rotating rod 8 needs to be rotated multiple times to make the winding drum 13 rotate one circle. While increasing the movement stroke, the force required to be applied is reduced, achieving a labor-saving effect, making it convenient to transport heavier materials. In this way, the above operation can facilitate the transportation of materials to the safe construction platform of the bridge.

[0025] See also Figure 1 , Figure 2 and Figure 4A movable plate 16 is slidably connected inside the base 1, and a movable groove matching the limit block 17 is opened inside the movable plate 16, and the limit block 17 is slidably connected to the movable groove; a limit ring 18 is welded and fixed on the outer side of the limit block 17, and a card slot matching the limit block 17 is opened inside the connecting frame 5, and the limit ring 18 is snap-fitted and connected to the card slot; both sides of the bottom of the connecting frame 5 are opened with impurity removal grooves 19 matching the movable plate 16, and two groups of movable plates 16 are provided, and are symmetrically distributed about the transverse center line of the connecting frame 5, the limit block 17 and the movable plate 16 constitute a sliding structure, and the limit block 17 and the connecting frame 5 constitute a snap-fit ​​structure.

[0026] In specific implementation, when inspecting the bridge, it is necessary to send the inspection personnel to a high place through the bridge safety construction platform to inspect the bridge. When cleaning the debris generated during the construction in the connecting frame 5, a group of movable plates 16 are pushed to move, and the movable plates 16 will move in the debris discharge groove 19. When the movable plate 16 moves a distance exceeding half of its own width, under the action of gravity, the movable plate 16 will rotate to one side through the inclined debris discharge groove 19. At this time, the inclined movable plate 16 will discharge the debris on the upper surface through the debris discharge groove 19, completing the cleaning of the connecting frame 5. At the same time, the limit block 17 will limit the movable plate 16 to prevent the movable plate 16 from being completely moved out;

[0027] After the cleaning is completed, the movable plate 16 is pulled to reset. When the limit block 17 contacts the slot inside the connecting frame 5, the limit block 17 will move downward under the action of gravity and engage with the slot to complete the limiting of the movable plate 16 to prevent the movable plate 16 from moving at will. The limit block 17 can limit the moving range of the limit block 17. In this way, the above operation can facilitate the cleaning of the bridge safety construction platform.

[0028] To sum up: when using a safe bridge construction platform that is convenient for transporting materials, the worker first enters the connecting frame 5, and then starts the hydraulic rod 2 to push the lifting frame 3 to rotate. The lifting frame 3 can push the connecting frame 5 to move upward, and the multi-section electric telescopic rod 4 will move upward synchronously to support both sides of the connecting frame 5. This is the feature of a safe bridge construction platform that is convenient for transporting materials. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.
