Description

TECHNICAL FIELD

[0001] The utility model relates to floating bridge technical field especially relates to a self -adjusting lifting type floating bridge. BACKGROUND

[0002] Floating bridge is a kind of bridge using high-strength float as the main bearing structure, usually including main cable, cable tower, anchor, suspender and bridge deck and other parts. Main cable is composed of high-strength steel cable, is supported by cable tower and is fixed in the anchor on both banks, and suspender suspends the bridge deck under the main cable. Floating bridge is suitable for crossing wide water area or canyon, and has high aesthetic value and engineering significance due to its unique design.

[0003] However, the bridge is often affected by natural environmental changes during use, especially the change of water level, which brings significant challenges to the safety and usability of the bridge. When the water level rises, such as flood, tide or reservoir storage, the water level may be higher than the bridge deck, causing the bridge to be submerged by water. In this case, the bearing structure of the bridge may be impacted and eroded by water flow, which is easy to cause structural damage under long-term action, and even causes the serious consequence of bridge collapse. At the same time, the water level higher than the bridge deck will also block the traffic, affect the normal travel and economic activities of people on both sides of the river, and bring inconvenience and economic loss to the society. The decrease of water level is also a problem that cannot be ignored. In the dry season or reservoir drainage, the water level may be lower than the bridge deck, causing the bridge pier and support part to be exposed to air. This not only changes the original stress state of the bridge, may cause structural stress concentration and fatigue damage, but also may accelerate the aging of the bridge part originally under the water due to exposure, and shorten the service life of the bridge. In addition, the water level lower than the bridge deck may also affect the aesthetics and use function of the bridge, and reduce its social benefits.

[0026] As shown in Figure 1 , Figure 3 , Figure 4 and Figure 5 , the left side of the bridge deck panel 1 is provided with a circular socket, the right side of the bridge deck panel 1 is provided with a plug column matched with the socket, and the left bottom and the right top of the bridge deck panel 1 are both provided with a notch. When the floating bridge is built, the adjacent bridge deck panels 1 are connected by the plug-in form of the plug column and the socket, and the notches between the adjacent bridge deck panels 1 are matched, and then the connection is fixed, which can facilitate the construction and maintenance of the floating bridge.

[0028] As shown in Figure 1 , Figure 3 , Figure 5 andFigure 6 As shown in the figure, two through holes 17 for the first steel wire rope 4 are opened on the left and right sides of the floating block 14. The first steel wire rope 4 is passed through the through hole 17 to connect all the floating blocks 14 together, and the two ends of the first steel wire rope 4 are connected to the two banks respectively, so as to improve the stability of the floating block 14.

[0029] As shown in the figure, Figure 1 , Figure 3 and Figure 4 , the top of the bridge deck panel 1 is fixedly connected with two mounting plates 2 on the left and right sides, and the left and right mounting plates 2 are symmetrically arranged front and back, and the side away from each other of the front and back mounting plates 2 is fixedly connected with three fixed blocks 3, the heavy object on the left and right banks is connected with the first steel wire rope 4, the first steel wire rope 4 is fixedly connected with the mounting plate 2 through the three fixed blocks 3, and the left and right banks are each fixedly connected with two guide plates 5, the two guide plates 5 are symmetrically arranged front and back, and further include an electric screw 6, a pressure plate 7 and a fixed plate 8, the side away from each other of the left and right guide plates 5 is fixedly connected with the fixed plate 8, the electric screw 6 is rotatably connected in the middle of the guide plate 5, the screw of the electric screw 6 passes through the top of the guide plate 5, the float ball liquid level meter 18 is electrically connected with the electric screw 6, the screw of the electric screw 6 is connected with three pressure plates 7 on the fixed plate 8, the pressure plate 7 on the electric screw 6 is threadedly connected with the electric screw 6, the pressure plate 7 on the fixed plate 8 is fixedly connected with the fixed plate 8, the pressure plate 7 is in contact with the first steel wire rope 4 on the mounting plate 2, and the pressure plate 7 is circumferentially provided with a sliding groove to prevent the first steel wire rope 4 from slipping. When a heavy object passes through the floating bridge, the electric screw 6 drives the screw to rotate to move the pressure plate 7 on it downward, the pressure plate 7 moves downward to extrude the first steel wire rope 4 on the mounting plate 2, thereby increasing the volume of the floating block 14 immersed in water, thereby improving the flexibility and stability of the floating bridge, so that the floating bridge can maintain a relatively consistent flatness in the loaded and unloaded states, when a ship passes through the floating bridge, the electric screw 6 reversely rotates the screw thereon to relax the pressure on the first steel wire rope 4, under the action of the buoyancy of the floating block 14, the floating block 14 drives the bridge deck panel 1 to move upward, so that the floating bridge rises until the floating block 14 resets, and part of the floating block 14 can be directly lifted, so that the ship passes through the bottom of the floating block 14, further improving the flexibility of the floating bridge.

[0030] As shown in the figure, Figure 1 , Figure 3 and Figure 4As shown, the bridge deck panel 1 is provided with an L-shaped support 9 and a falling prevention net 10, two L-shaped supports 9 are fixedly connected to the front and rear sides of the bridge deck panel 1, the L-shaped supports 9 are symmetrically arranged, the ends of the front and rear L-shaped supports 9 away from the bridge deck panel 1 are fixedly connected with the same fixing blocks 3 on the mounting plate 2, the fixing blocks 3 of the front and rear L-shaped supports are connected through the first steel wire rope 4, and the falling prevention net 10 is arranged between the left and right L-shaped supports 9 through the fixing blocks 3, so that the falling prevention net 10 can be reinforced. The falling prevention net 10 can effectively prevent people or objects from accidentally falling from the bridge deck, and improve the safety of passing.

[0031] F4 is the bearing weight, F1 is the bridge weight, F3 is the pulling force of the underwater heavy block, and F2 is the buoyancy provided by the floating block; F2=F4+F1+F3, F3+F4=F2-F1 is a constant, and the size of the increase of F4 is equal to the size of the decrease of F3. Among them, the material between the bridge and the heavy block is preferably a cable rope with small stress deformation, so that the length change is small when the pulling force changes, for example, the bridge deck needs to be stable in the vertical direction, and the water surface height is relatively stable in a short time, so the floating bridge maintains a fixed distance from the water surface, and the F2 buoyancy is long-term unchanged. When the underwater pulling force F3 is negative, it can play a supporting role, the greater the supporting role, the higher the cost, and the smaller the technical advantage, therefore, it is preferred to use in the range of F3 greater than zero and less than the tensile strength of the material.
