Description

Technical Field

[0001] The utility model relates to the technical field of floating bridges on water, in particular to an adaptive floating bridge on water. Background Technique

[0002] A floating bridge refers to a bridge floating on the water surface by using boats or floating boxes instead of bridge piers. There are two structural forms of floating bridges: the first is the traditional form, in which beams are erected on boats or floating boxes and then the bridge deck is paved. The second is the form of integrating boats and beams, either the boats are connected end to end in a longitudinal arrangement, or the boat bodies are closely arranged in a belt shape. To keep the axis position of the floating bridge from shifting, cable anchors need to be set upstream and downstream. To connect with both banks, transition beams or gangplanks need to be set on both banks. To adapt to the rise and fall of the water level, lifting docks or lifting trestles should also be set on both banks.

[0003] Floating bridges on water are applied in many water areas and can be used as docks, sightseeing walkways, water buildings, etc. In rivers and lakes with relatively small water level changes, it is relatively easy to connect with the revetment. However, in areas with large water level drops, more than 3 meters, and even more than 10 meters, and the revetment is steep, it becomes more difficult to connect the floating bridge with the revetment.

[0004] At present, there are few connection forms between floating bridges in water and the shore. When encountering a revetment with a large water level drop and a steep terrain (such as a storage reservoir), either an artificial control approach bridge is adopted, which is laborious, or a transition abutment is used to connect the approach bridge, which is difficult to construct and will cause damage to the dam during construction, with relatively high risks. Content of the Utility Model

[0005] In order to overcome the deficiencies that there are few connection forms between existing floating bridges in water and the shore, when encountering a revetment with a large water level drop and a steep terrain, either an artificial control approach bridge is adopted, which is laborious, or a transition abutment is used to connect the approach bridge, which is difficult to construct and will cause damage to the dam during construction, with relatively high risks, the embodiment of the present application provides an adaptive floating bridge on water. By extending the connecting arm on the large roller component to the inner side of the slide rail fixed to the concrete ladder by buried steel parts, a slide rail, a slide frame and a pulley are arranged between the two ends of the floating bridge on water and the two sliding approach bridges. When the sliding approach bridges and the floating bridge on water move up and down with the water level, the connecting arm can roll on the inner side of the slide rail, controlling the two sliding approach bridges to approach or move away from each other, which is beneficial to automatically adapt to the river width according to the change of the water level, without manual operation and is easy to construct.

[0032] The technical solution in the embodiment of the present application is to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0033] Embodiment 1:

[0034] This embodiment introduces the specific structure of an adaptive floating bridge on water. Specifically, refer to Figures 1 - 9 As shown, it includes a floating bridge structure on water and two shore approach bridge structures respectively located at both ends of the water structure. The floating bridge structure on water includes a floating bridge 4 in the water. On one side of both ends of the floating bridge 4 in the water, a sliding frame 8 is assembled and connected. On the surface of one end of the sliding approach bridge 1, a slide rail 3 is assembled. At the top inner wall and bottom inner wall of the sliding frame 8, a pulley 10 is assembled and connected. Inside the pulley 10, a second bearing 11 is arranged;

[0035] As Figure 2 and Figure 3 shown, the shore approach bridge structure includes a sliding approach bridge 1. At both corners of one end of the sliding approach bridge 1, large roller components 7 are arranged. At one end of the sliding approach bridge 1, a concrete ladder 6 is arranged. In the center of the top of the concrete ladder 6, a shore step 2 is processed;

[0036] Among them, as Figure 7 and Figure 8 shown, the second bearing 11 is connected to the sliding frame 8 through a shaft. By supporting the pulley 10 to roll on the inner wall of the slide rail 3 (the cross-section of the slide rail 3 is I-shaped), when the floating bridge 4 in the water and the two sliding approach bridges 1 (the connection method between the floating bridge 4 in the water and the sliding approach bridge 1 can be parallel or perpendicular, and is adjusted according to specific application requirements) span across the river, the sliding frame 8 can slide outside the slide rail 3 with the change of the water level, adjust the distance between the two sliding approach bridges 1, and has a good automatic adaptation ability;

[0037] Secondly, two slide rails 3 are provided and are respectively located on both sides of the shore step 2. By assembling a plurality of embedded steel parts 9 inside the slide rail 3, one end of the plurality of embedded steel parts 9 is embedded inside the concrete ladder 6. After the slide rail 3 is fixed to the concrete ladder 6, one side of the bottom of the large roller component 7 extends into the inside of one side of the slide rail 3 to complete the connection work between the sliding approach bridge 1 and the slide rail 3;

[0038] In some examples, the large roller component 7 includes a wheel 701. On one side of both ends of the wheel 701, a connecting arm 703 is connected in a rolling manner. The top of the wheel 701 is connected to a mounting seat 702 through a shaft. Inside one end of the mounting seat 702, a first bearing 704 is in interference fit;

[0039] Among them, by sleeving the first bearing 704 on the outside of the shaft, the wheel 701 is supported to rotate at one end of the first bearing 704, and the other end of the large roller component 7 is fixedly processed with the sliding approach bridge 1. When the large roller component 7 is connected to the slide rail 3, it is convenient for the connecting arm 703 to roll on the inner wall of the slide rail 3. Thus, when the two sliding approach bridges 1 and a floating bridge 4 in the water adjust the distance between the two sliding approach bridges 1 according to the water level change, one end of the sliding approach bridge 1 can face the shore step 2. When the floating bridge structure on the water moves up and down affected by the water level height, one end of the shore approach bridge structure slides at one end of the floating bridge structure on the water, and it is ensured that one end of the shore approach bridge structure is continuously connected to the river bank, and the movable characteristic of the connection between the shore approach bridge structure and the river bank is ensured:

[0040] In some examples, to ensure that the sliding approach bridge 1 and the floating bridge 4 in the water can float and move on the water surface and move up and down with the change of the water level, as Figure 7 shown, a plurality of floating cylinders 5 are provided at the bottoms of the sliding approach bridge 1 and the floating bridge 4 in the water. The plurality of floating cylinders 5 are assembled to the same horizontal plane. When the sliding approach bridge 1 and the floating bridge 4 in the water are erected on the water surface, it can be ensured that the sliding approach bridge 1 and the floating bridge 4 in the water move synchronously with the change of the water level-;

[0041] In some examples, to prevent people from falling into the water when walking on the top of the floating bridge 4 in the water and reduce the overall construction difficulty of the floating bridge 4 in the water, as Figure 9 shown, a plurality of pipe columns 12 are processed at the tops on both sides of the sliding approach bridge 1. A protective net 13 is assembled and connected between the plurality of pipe columns 12 on one side of the top of the sliding approach bridge 1. By assembling the protective net 13 with the pipe columns 12 on both sides of the sliding approach bridge 1 and cooperating with the traditional guardrail, it can prevent people from falling into the water from the top of the floating bridge 4 in the water.

[0042] By adopting the above technical solutions:

[0043] In the above design, by assembling the large roller component 7 (the large roller component 7 is composed of a wheel 701, two connecting arms 703 at both ends of the wheel 701, and an erection seat 702 connected to the sliding approach bridge 1) at two corners at one end of the sliding approach bridge 1, the connecting arm 703 on the large roller component 7 extends to the inside of the slide rail 3 fixed to the concrete ladder 6 by the buried steel part 9. A slide rail 3 and a slide frame 8 are arranged between the floating bridge 4 in the water and the sliding approach bridge 1. With the help of two pulleys 10, the slide rail 3 slides relative to the slide frame 8. When the water level changes, the sliding approach bridge 1 and the floating bridge 4 in the water move up and down with the water level. With the help of the rolling of the connecting arm 703 on the inside of the slide rail 3, the two sliding approach bridges 1 are controlled to approach or move away from each other, and the two sliding approach bridges 1 slide at both ends of the floating bridge 4 in the water respectively, which is beneficial to automatically adapt to the river width according to the change of the water level to ensure that one end of the floating bridge 4 in the water faces the area above the water on the shore step 2.

[0044] Embodiment 2:

[0045] Based on Embodiment 1, this embodiment introduces the specific structure of the shore approach bridge structure, such as Figures 10 - 12 shown, the shore approach bridge structure further includes two floating boxes 19. The bottoms of the two floating boxes 19 are respectively provided with a first cement platform 15 (constructed in water and exposed from the water surface) and a second cement platform 16. One side of the second cement platform 16 is provided with a shore cement platform 17. Positioning piles 14 are buried inside the four corners of the first cement platform 15 and the second cement platform 16;

[0046] Among them, the two floating boxes 19 located at both ends of the floating bridge 4 in the water are both assembled and fixed to the floating bridge 4 in the water. The first cement platform 15, the second cement platform 16 and the shore cement platform 17 are on a straight line. By providing two sliding approach bridges 1 (casters 20 are processed at the two corners at the bottom of one end of the two sliding approach bridges 1), one sliding approach bridge 1 is erected between the top of the floating box 19 on the top of the second cement platform 16 and the top of the shore cement platform 17 (the bottom of one end of the sliding approach bridge 1 is hinged to the top of one side of the shore cement platform 17), and the other sliding approach bridge 1 is erected between the tops of the two floating boxes 19 (the bottom of one end of the sliding approach bridge 1 is hinged to the top of one side of a floating box 19), which is convenient for the sliding approach bridge 1 and the floating bridge 4 in the water to slide the floating box 19 to the outside of the four positioning piles 14 during the process of rising and falling of the water level, and control the sliding approach bridge 1 to rotate around its corresponding hinge point;

[0047] Secondly, in order to facilitate personnel to get on and off the sliding approach bridge 1, as Figure 10 and Figure 11 shown, transition plates 18 are hingedly connected to the bottoms of both ends of the two sliding approach bridges 1. By making one end of the two transition plates 18 on one sliding approach bridge 1 respectively overlap the tops of the shore cement platform 17 and a floating box 19, and one end of the two transition plates 18 on the other sliding approach bridge 1 respectively overlap the tops of the two floating boxes 19, when one sliding approach bridge 1 rotates around its hinge point with the floating box 19 and the other sliding approach bridge 1 rotates around its hinge point with the shore cement platform 17, it can ensure that the transition plates 18 adapt to various angle changes.

[0048] By adopting the above technical solutions:

[0049] In the above design, two first cement platforms 15 are arranged inside two second cement platforms 16, and two shore cement platforms 17 are arranged outside two second cement platforms 16. When the floating bridge 4 in water is erected in water through the pontoons 5, the two floating boxes 19 fixedly assembled at both ends of the floating bridge 4 in water slide outside the positioning piles 14 on the tops of the two first cement platforms 15 respectively. Two sliding access bridges 1 are arranged between the first cement platform 15 and the shore cement platform 17. One is hinged to the floating box 19 on the top of the second cement platform 16 (one end of the sliding access bridge 1 far from the hinged end overlaps on the floating box 19 on the top of the first cement platform 15), and the other is hinged to the top of the shore cement platform 17 (one end of the sliding access bridge 1 far from the hinged end overlaps on the floating box 19 on the top of the second cement platform 16). When the water level changes, the floating bridge 4 in water can move up and down between the two first cement platforms 15, and the sliding access bridge 1 rotates around the hinge point (and the other end slides at the overlapping position, and the sliding is based on the support of the casters 20), which is convenient for application in a river channel with a large span and without the concrete ladder 6 and the sliding access bridge 1 constructed, and can automatically adapt to the water level change.

[0050] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
