Description

Technical Field

[0001] The present invention relates to the field of floating bridges and ferry pontoon bridges erected on rivers and ports. Specifically, it relates to a belt-type pontoon bridge with longitudinal and transverse connections. Background Art

[0002] The existing belt-type pontoon bridge is a ferry equipment for temporarily erecting a traffic-carrying bridge on rivers. The belt-type pontoon bridge is a belt-type pontoon bridge with single-lane traffic formed by longitudinally connecting multiple identical bridge-section box units on the water. With the development of requirements, stronger double-lane traffic capacity on water and a large water operation platform are needed. The existing belt-type pontoon bridge does not consider the transverse connection function between the bridge-section box units and cannot achieve the transverse connection between the bridge-section box units to form double-lane traffic capacity on water and a large water operation platform, which restricts the function of the belt-type pontoon bridge at the present stage. Summary of the Invention

[0003] To make up for the above deficiencies, the present invention provides a belt-type pontoon bridge with longitudinal and transverse connections, aiming to improve the problem that the existing belt-type pontoon bridge does not consider the transverse connection function between the bridge-section box units and cannot achieve the transverse connection between the bridge-section box units.

[0004] The present invention is implemented as follows:

[0005] A belt-type pontoon bridge with longitudinal and transverse connections includes a pontoon bridge unit body and a pointed pontoon assembly.

[0006] The pointed pontoon assembly includes a transverse connection pointed pontoon, a transverse connection ark pontoon, a first connecting member, a turning hinge, a deck transverse fastener, a transverse connection joint, a transverse connection ear plate, a pointed pontoon fixing ear plate, and a second connecting member. The lower side of the transverse connection pointed pontoon is hinged to the lower side of the transverse connection ark pontoon through the turning hinge, the upper side of the transverse connection pointed pontoon is fixedly connected to the upper side of the transverse connection ark pontoon through the first connecting member, the side of the transverse connection ark pontoon away from the transverse connection pointed pontoon is arranged on the pontoon bridge unit body. The deck transverse fastener includes a deck transverse fastener and an ear plate seat. The deck transverse fastener and the ear plate seat are symmetrically and fixedly connected to both ends of the deck on the upper side of the transverse connection ark pontoon. The deck transverse fastener and the ear plate seat are located on the side of the transverse connection ark pontoon close to the transverse connection pointed pontoon. The transverse connection joint and the transverse connection ear plate are symmetrically and fixedly connected to both ends of the deck on the upper side of the transverse connection pointed pontoon. The transverse connection joint and the transverse connection ear plate are located on the side of the transverse connection pointed pontoon close to the transverse connection ark pontoon. The pointed pontoon fixing ear plate is fixedly connected to both ends of the side wall of the transverse connection pointed pontoon away from the transverse connection joint. One end of the second connecting member is hinged to the side wall of the transverse connection ark pontoon, and the other end of the second connecting member can be inserted into the pointed pontoon fixing ear plate.

[0007] In an embodiment of the present invention, the first connecting member includes a first ear plate and a second ear plate. The first ear plate and the second ear plate are respectively disposed corresponding to the upper parts of the cross-connected pointed boat and the cross-connected ark-shaped boat, and the first ear plate and the second ear plate are hinged by a first pin shaft.

[0008] In an embodiment of the present invention, the lateral connection joint includes a third ear plate and a worm and worm gear mechanism. The third ear plate is disposed on one side of the upper part of the cross-connected pointed boat, and the worm and worm gear mechanism is disposed on one side of the upper part of the cross-connected pointed boat. The third ear plate and the lateral connection ear plate on the adjacent cross-connected pointed boat are hinged by a second pin shaft, and the worm and worm gear mechanism can drive the second pin shaft to insert into the third ear plate and the lateral connection ear plate on the adjacent cross-connected pointed boat.

[0009] In an embodiment of the present invention, a push connecting rod is disposed on one side of the upper part of the cross-connected pointed boat.

[0010] In an embodiment of the present invention, the second connecting member includes a rotating rod and an elastic pin. The elastic pin is disposed at the end of the rotating rod, and the end of the rotating rod away from the elastic pin is rotatably connected to the lower part of the cross-connected ark-shaped boat. The elastic pin can be inserted into the pointed boat fixed ear plate.

[0011] In an embodiment of the present invention, a limiting block is disposed on the side wall of the cross-connected ark-shaped boat, and the limiting block can block the end of the rotating rod.

[0012] In an embodiment of the present invention, a round button is disposed on the side wall of the cross-connected ark-shaped boat.

[0013] In an embodiment of the present invention, anti-collision plates are correspondingly disposed on the cross-connected pointed boat and the cross-connected ark-shaped boat.

[0014] The beneficial effects of the present invention are as follows: A belt-type pontoon bridge with vertical and horizontal connections designed by the present invention, when in use, releases the fixation of the first connecting piece on the upper sides of the transverse connecting pointed pontoon and the transverse connecting ark-shaped pontoon, flips down the transverse connecting pointed pontoon, and fixes the transverse connecting pointed pontoon and the transverse connecting ark-shaped pontoon in a folded state through the second connecting piece, completing the folding operation of the transverse connecting pointed pontoon and the transverse connecting ark-shaped pontoon. After the folding and in-water deployment operations of the belt-type pontoon bridge are completed, the ends of adjacent pointed pontoon components close to the transverse connecting pointed pontoon are brought closer and aligned with each other, and the deck transverse buckles and ear plate seats on the upper sides of adjacent transverse connecting ark-shaped pontoons are aligned with each other and the deck transverse buckles are buckled into the ear plate seats, achieving the purpose of fixing the upper sides of adjacent transverse connecting ark-shaped pontoons. At this time, the transverse connecting joints on the transverse connecting pointed pontoon and the transverse connecting ear plates on the adjacent transverse connecting pointed pontoons are aligned and fixed by hinging, achieving the purpose of fixing the transverse connecting pointed pontoon and the adjacent transverse connecting pointed pontoons. By fixing the transverse connecting pointed pontoons to each other, the purpose of fixing the upper sides of adjacent transverse connecting ark-shaped pontoons is achieved, completing the transverse connection of adjacent belt-type pontoon bridges, effectively improving the problem that the existing belt-type pontoon bridge does not consider the transverse connection function between the bridge section box body units and cannot achieve the transverse connection between the bridge section box body units, realizing the double-lane traffic capacity and increasing the transverse area when forming the water operation platform, meeting the requirements of free combination and flexible connection for the transverse connection of the belt-type pontoon bridge. At the same time, when two sets of belt-type pontoon bridges are transversely connected and used as a bridge for vehicle passage, heavy-duty double-lane traffic can be achieved.

[0015] When it is necessary to retract the transverse connecting pointed pontoon, pull the elastic pin to release the fixation of the second connecting piece on the transverse connecting pointed pontoon, flip up the transverse connecting pointed pontoon, and fix the upper sides of the transverse connecting pointed pontoon and the transverse connecting ark-shaped pontoon through the first connecting piece, thereby realizing the fixation after the transverse connecting pointed pontoon is flipped up. The folding and fixation of the transverse connecting pointed pontoon and the transverse connecting ark-shaped pontoon are convenient and fast, without the need to remove or install any components, facilitating rapid deployment.

[0039] Please refer to Figures 6 to 9, extract the first pin shaft hinged on the first ear plate 231 and the second ear plate 232, release the fixation of the first connecting member 230 on the upper sides of the transverse connecting sharp boat 210 and the transverse connecting ark boat 220, turn down the transverse connecting sharp boat 210, rotate the rotating rod 291, and by pulling the elastic bolt 292, insert the pin body on the elastic bolt 292 into the sharp boat fixing ear plate 280 to fix the transverse connecting sharp boat 210 and the transverse connecting ark boat 220 in the folded state, completing the folding operation of the transverse connecting sharp boat 210 and the transverse connecting ark boat 220. After the folding and in-water deployment operations of the belt-type pontoon bridge are completed, make the ends of adjacent pontoon assemblies 200 close to the transverse connecting sharp boat 210 approach and align with each other, align the deck transverse buckles 251 and the ear plate seats 252 on the upper sides of adjacent transverse connecting ark boats 220 and make the deck transverse buckles 251 snap into the ear plate seats 252 to achieve the purpose of fixing the upper sides of adjacent transverse connecting ark boats 220. At this time, the third ear plate 261 on the transverse connecting sharp boat 210 and the transverse connecting ear plate 270 on the adjacent transverse connecting sharp boat 210 are aligned, and the second pin shaft is driven by the worm and worm gear mechanism 262 to insert into the third ear plate 261 and the transverse connecting ear plate 270 on the adjacent transverse connecting sharp boat 210 to achieve the purpose of fixing the transverse connecting sharp boat 210 and the adjacent transverse connecting sharp boat 210. By fixing the transverse connecting sharp boats 210 to each other, the purpose of fixing the upper sides of adjacent transverse connecting ark boats 220 is achieved, completing the purpose of the transverse connection of adjacent belt-type pontoon bridges, effectively improving the problem that the existing belt-type pontoon bridge does not consider the transverse connection function between the bridge section box units and cannot realize the transverse connection between the bridge section box units, and realizing the two-lane traffic capacity and increasing the transverse area when forming the water operation platform.

[0040] Specifically, the working principle of the cross-connected belt-type pontoon bridge: Pull out the first pin shaft hinged on the first ear plate 231 and the second ear plate 232, release the fixation of the first connecting member 230 to the upper sides of the cross-connected pointed pontoon 210 and the cross-connected square pontoon 220, flip down the cross-connected pointed pontoon 210, rotate the rotating rod 291, and by pulling the elastic bolt 292, insert the pin body on the elastic bolt 292 into the pointed pontoon fixing ear plate 280 to fix the cross-connected pointed pontoon 210 and the cross-connected square pontoon 220 in the folded state, completing the folding operation of the cross-connected pointed pontoon 210 and the cross-connected square pontoon 220. After the folding and in-water deployment operations of the belt-type pontoon bridge are completed, make the ends of the adjacent pointed pontoon assemblies 200 close to the cross-connected pointed pontoon 210 approach and align with each other, align the deck transverse buckles 251 and the ear plate seats 252 on the upper sides of the adjacent cross-connected square pontoons 220 and make the deck transverse buckles 251 buckle into the ear plate seats 252 to achieve the purpose of fixing the upper sides of the adjacent cross-connected square pontoons 220. At this time, the third ear plate 261 on the cross-connected pointed pontoon 210 and the transverse connection ear plate 270 on the adjacent cross-connected pointed pontoon 210 are aligned, and the second pin shaft is driven by the worm and gear mechanism 262 to insert into the third ear plate 261 and the transverse connection ear plate 270 on the adjacent cross-connected pointed pontoon 210 to achieve the purpose of fixing the cross-connected pointed pontoon 210 and the adjacent cross-connected pointed pontoon 210. By fixing the cross-connected pointed pontoons 210 to each other, the purpose of fixing the upper sides of the adjacent cross-connected square pontoons 220 is achieved, completing the purpose of the transverse connection of the adjacent belt-type pontoon bridges, effectively improving the problem that the existing belt-type pontoon bridge does not consider the transverse connection function between the bridge section box units and cannot achieve the transverse connection between the bridge section box units, realizing the dual-lane traffic capacity and increasing the transverse area when forming the water operation platform, meeting the requirements of the free combination and flexible connection of the transverse connection of the belt-type pontoon bridge. At the same time, after the two sets of belt-type pontoon bridges are transversely connected and used as a bridge for vehicle passage, dual-lane heavy-load traffic can be achieved.

[0041] When it is necessary to retract the cross-connected pointed pontoon 210, pull the elastic bolt 292 to extract the pin body on the elastic bolt 292 from the pointed pontoon fixing ear plate 280, rotate the rotating rod 291, the elastic bolt 292 leaves the pointed pontoon fixing ear plate 280, flip up the cross-connected pointed pontoon 210, and fix the first ear plate 231 and the second ear plate 232 through the first pin shaft to fix the cross-connected pointed pontoon 210 after it is flipped up. The folding and fixing of the cross-connected pointed pontoon 210 and the cross-connected square pontoon 220 are convenient and fast, without the need to remove or install any components, facilitating rapid deployment.
