Description

Technical Field

[0001] The utility model relates to the technical field of bridge expansion devices, and specifically relates to a floating bridge expansion device. Background Art

[0002] As is well known, a floating bridge refers to a bridge that uses ships or floating boxes instead of bridge piers and floats on the water surface. Affected by the impact force generated by water flow and vehicle driving, the bridges will move away from each other or move up and down out of alignment. At this time, a floating bridge expansion device is required to connect the bridge main bodies together.

[0003] In real life, common floating bridge expansion devices generally install rubber waterstops between several adjacent profiled steels to receive rainwater falling from above. Most rubber waterstops are rubber products. When nails, stones or other hard substances fall from the gap between several profiled steels onto the rubber waterstop, with the swing of the floating bridge, these substances roll on the rubber waterstop, which will cause scratches and damage to the rubber waterstop, thus reducing the service life of the rubber waterstop. And this device does not have a device to block the falling substances such as stones, so the practicability is not very good and there is still room for improvement. Content of the Utility Model

The protection plate includes several sliding grooves and is slidably arranged with the corresponding telescopic plate. One end of each of the several sliding grooves is provided with a spring, and the other end of each of the several springs is fixedly connected with one end of the corresponding telescopic plate.

[0008] Furthermore, each of the several movable devices is spherical, which is convenient for rolling in the corresponding movable groove. The outer part of each of the several movable devices is coated with a waterproof coating to improve the waterproof effect of the movable device.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-5 , a floating bridge expansion device of the present invention includes several special-shaped steels 1. At one end of each of the several special-shaped steels 1, several movable grooves 2 are provided, and movable devices 3 are installed. At one end of each of the several movable devices 3, telescopic plates 4 are provided. When the several special-shaped steels 1 move up and down or left and right, the movable devices 3 move up and down in the movable grooves 2, driving the telescopic plates 4 to move up and down. Thus, the movable devices 3 achieve the function of adjusting the swinging angle of the telescopic plates 4. At one end where the several telescopic plates 4 are close to each other, a protection plate 5 is slidably connected, which is used to receive sundries such as gravel falling from the gap between the several special-shaped steels 1. The protection plate 5 includes several slide grooves 6 and is slidably arranged corresponding to the telescopic plates 4. At one end of each of the several slide grooves 6, a spring 7 is provided, and the other end of each of the several springs 7 is fixedly connected to one end of the corresponding telescopic plate 4. When the several special-shaped steels 1 return from the misaligned state to the original state, the several springs 7 pull the corresponding telescopic plates 4 to assist the telescopic plates 4 to slide into the slide grooves 6.

[0024] Each of the several movable devices 3 is spherical, which is convenient for rolling in the corresponding movable groove 2, so that the telescopic plate 4 adjusts its own angle as the several special-shaped steels 1 swing. A waterproof coating is applied to the outside of each of the several movable devices 3 to improve the waterproof effect of the movable devices 3. When it rains, the rainwater contacts the movable devices 3, and the waterproof coating separates the rainwater from the movable devices 3, thus avoiding the direct contact between the rainwater and the movable devices 3 and preventing their corrosion.

[0025] The movable grooves 2 of the several special-shaped steels 1 are arranged in an up-and-down staggered manner, which is convenient for the corresponding telescopic plates 4 to be arranged in an up-and-down staggered manner, so as to avoid their intersection and enable the lengths of both to be larger. There is a gap between the several telescopic plates 4, which is convenient for the protection plate 5 to be provided with several slide grooves 6. An arc groove 15 is provided at the upper part of the protection plate 5, which is convenient for the objects falling from above to roll to the middle of the protection plate 5 instead of rolling to both sides of the protection plate 5 and then falling onto the telescopic plates 4.

[0026] At one end of several profiled steel bars 1, several clamping grooves 8 are provided, and clamping bars 9 are clamped thereto. Between several clamping bars 9, a rubber water stop 10 is provided, which plays a role in waterproofing and improves the service life of the floating bridge expansion device.

[0027] On both sides of several profiled steel bars 1, installation grooves 11 are respectively provided. In several installation grooves 11, several anchoring plates 12 are welded to fix the profiled steel bars 1 and improve the stability of the profiled steel bars 1. At one end of several anchoring plates 12, reinforcing steel bars 13 are provided.

[0028] On the upper part of several profiled steel bars 1, shielding plates 14 are provided to shield the edge parts of the profiled steel bars 1 and prevent foreign objects such as stones from falling onto the expansion plate 4 from the side wall edges of the profiled steel bars 1.

[0029] In summary, when the floating bridge expansion device is in use, when a vehicle is driving on the floating bridge and the floating bridge undergoes vertical dislocation or tensile movement under the impact force generated by the water flow and the vehicle driving, several profiled steel bars 1 move away from each other. At this time, the movable device 3 rolls in the movable groove 2, adjusts the angle of the expansion plate 4 as the misalignment angle of the profiled steel bars 1 changes, and as the profiled steel bars 1 move away from each other, the expansion plate 4 extends a certain distance out of the chute 6 of the protective plate 5, and then cooperates with the protective plate 5 to shield above the rubber water stop 10. Stones and other sundries falling from the gap between several profiled steel bars 1 fall onto the protective plate 5 and slide along the arc-shaped groove 15 to the middle of the protective plate 5. When there is a certain amount of sundries, the staff can use a vacuum cleaner or other tools convenient for clamping stones and other items to clean up the sundries.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
