Description

Technical Field

[0001] This utility model relates to the field of box girder construction technology, and in particular to a portable traveling vehicle for box girder construction sites on high-speed railway and highway sections. Background Technology

[0002] Box girders are a type of beam in bridge engineering. Box girders need to be prefabricated and installed on site. Furthermore, the construction and maintenance of box girders involve high-altitude operations and may cross rivers, streams, or canyons. Existing high-altitude construction platforms for box girders include: the most traditional scaffolding, cantilever work platforms or suspended baskets, elevator platforms, and temporary construction work platforms.

[0003] Existing technology CN220847086U discloses a mobile aerial work trolley for steel box girder construction, comprising several channel-shaped frame units connected end-to-end on the bottom surface of the steel box girder, a suspension body connected to the endpoints of the channel-shaped frame units, a plastic nylon support wheel with one end attached to the wind nozzle of the steel box girder and the other end fixed to the suspension body, and fasteners. Each channel-shaped frame unit includes a channel-shaped frame welded from several horizontal beams and several vertical columns, and a base plate disposed within the channel-shaped frame. The suspension body is a C-shaped frame welded from vertical and horizontal bars. The channel-shaped frame units are fixedly connected to each other by fasteners. However, when using the above-mentioned aerial work trolley for box girder installation, when encountering a bridge pier, it is necessary to disassemble the aerial work trolley on one side of the pier and then reinstall it on the other side of the pier before proceeding with the subsequent installation. This requires multiple installation and disassembly operations at high altitudes, which is cumbersome, affects the construction progress, and reduces safety.

[0004] Therefore, there is an urgent need to provide portable mobile vehicles for the construction of box girders in high-speed railway and highway sections, which can reduce construction difficulty, increase construction speed, and improve safety compared to existing technologies.

[0009] Furthermore, the second connecting assembly includes a third motor, a second rotating rod, and a second connecting block. The output end of the third motor is fixedly connected to the side wall of the movable frame. The output end of the third motor passes through the side wall of the movable frame and is fixedly connected to the second rotating rod. Two second connecting blocks are fixedly connected to the upper wall of the second rotating rod. The two second connecting blocks are arranged in a one-to-one correspondence with the two first connecting blocks. When both movable frames are in a horizontal state, the two second connecting blocks clamp the ends of the two movable frames, and the corresponding first connecting blocks are connected to the second connecting blocks.

[0015] Furthermore, the wheel is connected to a first motor, which drives the wheel to move.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, by setting up a drive assembly, a first connecting assembly, and a second connecting assembly, allows the portable vehicle to pass over bridge piers without requiring complete disassembly.

The lower side of the first platform 4 away from the ladder 3 it is connected to the second platform 5. The drive assembly is fixedly installed at the lower end of the second platform 5. The movable frame 9 is rotatably connected to the end of the second platform 5 near the other second platform 5. The drive assembly is rotatably connected to the lower part of the movable frame 9. The drive assembly drives the movable frame 9 to rotate relative to the second platform 5. When both movable frames 9 are in a horizontal state, the ends of the two movable frames 9 away from the second platform 5 they are connected to are detachably connected through the first connecting assembly 12 and the second connecting assembly 13.

[0024] The lower wall of the frame 1 is equipped with two wheels 2, which are slidably connected to the upper wall of the box girder 7. The wheels 2 are connected to the first motor 11, which drives the wheels 2, thereby enabling the frame 1 to move on the box girder 7. The first platform 4 and the ladder 3 are fixedly connected by a diagonal tie rod 6.

[0025] like Figure 3 As shown, the movable frame 9 is a rectangular frame, and a fixed rod 91 is fixedly connected inside the movable frame 9. The drive assembly includes a fixed plate 8 and an electric push rod 10.

The electric push rod 10 is rotatably connected to the side wall of the fixed plate 8, and the output end of the electric push rod 10 is rotatably connected to the fixed rod 91. A hemispherical groove is provided at the connection between the fixed plate 8 and the electric push rod 10, and a hemispherical groove is also provided at the connection between the fixed rod 91 and the output end of the electric push rod 10. This ensures that when the electric push rod 10 pushes the movable frame 9 from a horizontal state to a vertical state or from a vertical state to a horizontal state, there will be no interference between the two ends of the electric push rod 10 and the fixed plate 8 and the fixed rod 91, and it can rotate freely.

[0026] like Figure 3 , Figure 4 As shown, the two movable frames 9 are respectively provided with a first connecting component 12 and a second connecting component 13 on their opposite end faces. The first connecting component 12 is provided on both sides of the end face of one movable frame 9, and the second connecting component 13 is provided on both sides of the end face of the other movable frame 9. The two first connecting components 12 and the two second connecting components 13 are respectively provided in a one-to-one correspondence.

[0027] The first connecting assembly 12 includes a second motor 121, a first rotating rod 122, and an electromagnet 124. The second motor 121 is fixedly connected to the side wall of the movable frame 9. The output end of the second motor 121 passes through the side wall of the movable frame 9 and is fixedly connected to the side wall of the first rotating rod 122. The output end of the second motor 121 is rotatably connected to the movable frame 9. The first rotating rod 122 is L-shaped and includes an integrally connected vertical part and a horizontal part. The vertical part of the first rotating rod 122 is fixedly connected to the output end of the second motor 121. Two first connecting blocks 123 are integrally connected to the lower wall of the horizontal part. The two first connecting blocks 123 are spaced apart. The distance between the two first connecting blocks 123 is the same as the thickness of the contact ends of the two movable frames 9. That is, the two first connecting blocks 123 can clamp the contact ends of the two movable frames 9. An electromagnet 124 is fixedly connected to the lower wall of each first connecting block 123. The electromagnet 124 is electrically connected to a power source. The power source is fixed on the movable frame 9. The electrical connection relationship between the power source and the electromagnet 124 adopts the connection relationship in the prior art. The specific connection will not be described in detail here.

[0028] The second connecting assembly 13 includes a third motor 131, a second rotating rod 132, and a magnet 134. The third motor 131 is fixedly connected to the side wall of the movable frame 9. The output end of the third motor 131 passes through the side wall of the movable frame 9 and is fixedly connected to the side wall of the second rotating rod 132. The output end of the third motor 131 is rotatably connected to the side wall of the movable frame 9. The second rotating rod 132 is also L-shaped and includes an integrally connected vertical part and a horizontal part. The vertical part of the second rotating rod 132 is connected to the output end of the third motor 131. The lower wall of the horizontal part of the second rotating rod 132 is fixedly connected to the outlet end. Two second connecting blocks 133 are fixedly connected.

The magnets 134 in the second connecting assembly 13 are set one-to-one with the magnets 134 in the first connecting assembly 12.

[0029] like Figure 1As shown, when the portable vehicle moves between the two piers 14, the output end of the electric push rod 10 extends, and the ends of the two movable frames 9 contact each other. The second motor 121 and the third motor 131 start, driving the first rotating rod 122 and the second rotating rod 132 to a horizontal state. The two first connecting blocks 123 on the lower wall of the first rotating rod 122 clamp the two movable frames 9, and the two second connecting blocks 133 on the upper wall of the second rotating rod 132 clamp the two movable frames 9. At this time, the electromagnet 124 is energized, and each electromagnet 124 attracts the corresponding magnet 134. The first connecting component 12 and the second connecting component 13 fix the two movable frames 9 together.

[0030] like Figure 2 As shown, when the portable vehicle is about to move across the pier 14, the electromagnet 124 is de-energized, and the second motor 121 and the third motor 131 are started, respectively driving the first rotating rod 122 and the second rotating rod 132 to a vertical position. The electric push rod 10 retracts, driving the corresponding movable frame 9 to rotate, and finally to a vertical position. The first motor 11 drives the wheel 2 to rotate, thereby enabling the portable vehicle to pass through the pier 14. After passing through the pier 14, the two movable frames 9 are then fixed.

[0031] This invention, by setting up a drive assembly, a first connecting assembly 12, and a second connecting assembly 13, allows the portable vehicle to pass over the bridge pier 14 without complete disassembly. Only the first connecting assembly 12 and the second connecting assembly 13 need to be separated, and then the drive assembly drives the two movable frames 9 to rotate to a vertical position, allowing the portable vehicle to safely pass over the bridge pier 14. After passing the bridge pier 14, the drive assembly drives the two movable frames 9 to a horizontal position, and then the first connecting assembly 12 and the second connecting assembly 13 fix the two movable frames 9 together. This reduces construction difficulty, increases construction speed, and ensures safety during construction.

[0032] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
