Technical Field

[0001] The utility model relates to the technical field of temporary traffic guarantee for highway bridges, in particular to a temporary traffic guarantee device before installation of a highway bridge expansion joint. Background Art

[0002] Before the installation of expansion joints on highway bridges, ordinary square wood or gravel is usually installed above the expansion joints to ensure the safety and smoothness of temporary traffic. The main purpose of this temporary traffic guarantee device is to provide stable traffic conditions for passing vehicles during the installation of the expansion joints, while ensuring the safety and order of the construction area.

DETAILED DESCRIPTION

[0023] 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.

[0024] When implementing: Figure 1-4As shown, a temporary traffic guarantee device before the installation of a highway bridge expansion joint comprises: a bearing plate 1; a protection mechanism 2, wherein the protection mechanism 2 for protecting the bearing plate 1 is arranged at the bottom of the bearing plate 1; wherein the protection mechanism 2 comprises a steel plate 21 fixedly connected to both sides of the bottom of the bearing plate 1, the bottom of the steel plate 21 is fixedly connected to support rods 25 distributed in equal rows, the surface of the support rod 25 is slidably connected to a support cylinder 22, the inner bottom wall of the support cylinder 22 is fixedly connected to a butterfly spring 24, the top of the butterfly spring 24 is fixedly connected to the support cylinder 22, and the inner bottom wall of the butterfly spring 24 is fixedly connected to the support cylinder 22.

[0025] When it is necessary to place a temporary traffic guarantee before installing the expansion joint of a highway bridge, the load-bearing plate 1 is assembled by bolts to a suitable length, and the assembled load-bearing plate 1 is installed on the expansion joint, so that vehicles can pass on the load-bearing plate 1. The pressure of the vehicle's driving is transmitted to the load-bearing plate 1, and the steel plate 21 shares the pressure borne by the load-bearing plate 1, and the support tube 22, butterfly spring 24, support rod 25 and elastic steel block 26 absorb the vibration and impact force generated by the vehicle on the load-bearing plate 1 when driving, thereby improving the load-bearing capacity of the load-bearing plate 1 and avoiding the load-bearing plate 1 from being crushed and deformed.

[0026] When the temporary passage guarantee is not in use, the bolts are turned to separate the bearing plate 1, thereby releasing the bearing plate 1 from the expansion joint. The disassembly and assembly of the temporary passage guarantee is simple, which facilitates the reuse of the temporary passage guarantee device and reduces the investment cost of the temporary passage guarantee device.

[0027] like Figure 3 As shown, a reinforcing frame 2714 is fixedly connected to the bottom of the load-bearing plate 1, and one side of the reinforcing frame 2714 is fixedly connected to one side of the steel plate 21. Since the reinforcing frame 2714 is in an "X" shape, the reinforcing frame 2714 can disperse the pressure when the vehicle is running, and evenly transfer the pressure to various positions of the load-bearing plate 1, thereby reducing the single-point pressure on the surface of the load-bearing plate 1 and reducing the risk of its deformation.

[0028] like Figure 4As shown, both sides of the top of the support plate 23 are slidably connected with a slider 275, the inner side of the slider 275 is hinged with a push block 274, the top of the push block 274 is hinged to the bottom of the bearing plate 1, one side of the slider 275 is fixedly connected with a slide bar 277, the surface of the slide bar 277 is slidably connected with a slide cylinder 276, the inner wall of the slide cylinder 276 is connected with a through pipe 278, the top of one of the support plates 23 is fixedly connected with a liquid storage box 279, the bottom of the liquid storage box 279 is connected to the top of the through pipe 278, the inner wall of the liquid storage box 279 is threadedly connected with a threaded rod 2711, one end of the threaded rod 2711 is rotatably connected with a rubber block 2710, the inner wall of the slide cylinder 276 is fixedly connected with a second spring 2712, and the other end of the second spring 2712 is fixedly connected to one end of the slide bar 277. The tops of the two push blocks 274 are hinged, and the surface of the slide cylinder 276 is fixedly connected to the inner wall of the support plate 23. Hydraulic oil is stored in the liquid storage tank 279 .

[0029] It should be noted that the steel plate 21, butterfly spring 24, damping cylinder 271, damping rod 272, first spring 273, second spring 2712, etc. in the above description are all relatively mature devices in the existing technology, and the specific models can be selected according to actual needs.

[0030] When the height of the supporting plate 1 needs to be adjusted, the threaded rod 2711 is rotated. The threaded rod 2711 rotates and drives the rubber block 2710 to move in the liquid storage tank 279, so that the hydraulic oil in the liquid storage tank 279 is transported to each slide cylinder 276 through the through pipe 278. The excess hydraulic oil in the slide cylinder 276 pushes the slide rod 277 and the slider 275 to move. The movement of the slider 275 drives the push block 274 to adjust the angle. During the angle adjustment, the push block 274 pushes the supporting plate 1 to move up to a suitable height, so that the adjusted height of the supporting plate 1 can be in the same horizontal state as the road surface.

[0031] like Figure 4 As shown, the front end of the rubber block 2710 is fixedly connected to a guide rod 2713, and the surface of the guide rod 2713 is slidably connected to the inner wall of the liquid storage box 279. The movement of the rubber block 2710 drives the guide rod 2713 to move in the liquid storage box 279, and the guide rod 2713 limits the moving rubber block 2710.

[0032] When the utility model is in use, the threaded rod 2711 is rotated, and the threaded rod 2711 rotates to drive the rubber block 2710 to move in the liquid storage box 279, so that the hydraulic oil in the liquid storage box 279 is respectively transported to each slide cylinder 276 through the through pipe 278. The excessive hydraulic oil in the slide cylinder 276 pushes the slide rod 277 and the slider 275 to move, and the slider 275 moves to drive the push block 274 to adjust the angle. During the angle adjustment, the push block 274 pushes the bearing plate 1 to move to a suitable height, so that the height of the bearing plate 1 can be in the same horizontal state as the road surface. After the bearing plate 1 is assembled by bolts to reach a suitable length, the assembled bearing plate 1 is installed on the expansion joint, so that the vehicle can pass on the load-bearing plate 1. The pressure of the vehicle driving is transmitted to the load-bearing plate 1. The steel plate 21 shares the pressure of the load-bearing plate 1, the support tube 22, the butterfly spring 24, the support rod 25 and the elastic steel block 26 absorb the vibration and impact force of the vehicle on the load-bearing plate 1 when driving. The "X"-shaped reinforcement frame 2714 can disperse the pressure of the vehicle when driving, and evenly transmit the pressure to various positions of the load-bearing plate 1, thereby reducing the single-point pressure on the surface of the load-bearing plate 1 and reducing its deformation risk, thereby improving the bearing capacity of the load-bearing plate 1 and avoiding the rolling deformation of the load-bearing plate 1.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
