Description

Technical Field

[0001] This utility model relates to the field of construction platform technology, specifically a highway bridge construction platform. Background Technology

[0002] Currently, in the construction of highways, in order to reduce the occupation of farmland and to cross special terrain, the construction of viaducts is often adopted. During the construction of highway bridges, construction platforms are often built for the construction on the sides of the bridge.

[0003] Most existing bridge construction platforms are equipped with protective railings to protect construction workers. However, during the lifting and lowering of the construction platform, significant swaying can easily occur, causing fear among the workers standing on the platform and seriously affecting their work quality and efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned shortcomings by providing a highway bridge construction platform that can effectively reduce the large-scale shaking generated during the lifting and lowering process, avoid causing fear among the workers on the construction platform, and improve the work quality and efficiency of the workers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A highway bridge construction platform includes a drive vehicle, a rectangular platform mounted on one side of the drive vehicle, and four telescopic rods (one, two, three, and four) positioned near the four corners of the rectangular platform for connecting the tops of the four telescopic rods to a support frame. The drive vehicle is connected to the support frame via a connecting frame. A hydraulic cylinder is mounted on the support frame, with the piston rod of the hydraulic cylinder extending vertically downwards to drive and connect to the rectangular platform. A synchronization structure one is provided between telescopic rod one and telescopic rod two, a synchronization structure two is provided between telescopic rod two and telescopic rod three, and a synchronization structure three is provided between telescopic rod three and telescopic rod four.

[0007] Furthermore, the telescopic rod one, telescopic rod two, telescopic rod three, and telescopic rod four include outer tube one, outer tube two, outer tube three, and outer tube four with their top ends fixed to the support frame. The top ends of the outer tube one, outer tube two, outer tube three, and outer tube four are slidably connected to sliding columns one, sliding columns two, sliding columns three, and sliding columns four inside the outer tube one, outer tube two, outer tube three, and outer tube four. The bottom ends of the sliding columns one, sliding columns two, sliding columns three, and sliding columns four are respectively fixed to the rectangular platform. The inner sidewalls of the outer tube one, outer tube two, outer tube three, and outer tube four are respectively provided with vertical sliding grooves. The sliding columns one, sliding columns two, sliding columns three, and sliding columns four are respectively provided with protrusions facing the sliding grooves. During the up-and-down sliding process of the sliding columns one, sliding columns two, sliding columns three, and sliding columns four, the protrusions slide up and down along the sliding grooves.

[0008] Furthermore, a synchronization opening is provided on one side of the outer tube one, and a rack one is provided on the sliding column one facing the synchronization opening one; a synchronization opening two is provided on one side of the outer tube two, and a rack two is provided on the sliding column two facing the synchronization opening two; the synchronization structure one includes a synchronization frame one fixed on the support frame between the telescopic rod one and the telescopic rod two, and a rotating shaft one rotatably connected to the synchronization frame one; a synchronization gear one and a synchronization gear two are fixed on the rotating shaft one; the synchronization gear one meshes with the rack one, and the synchronization gear two meshes with the rack two.

[0009] Furthermore, a synchronous opening three is provided on the other side of the outer tube two, and a rack three is provided on the sliding column two directly opposite the synchronous opening three. With the axis of the outer tube two as the center, the synchronous opening three and the synchronous opening two are at a 90-degree angle. A synchronous opening four is provided on one side of the outer tube three, and a rack four is provided on the sliding column three directly opposite the synchronous opening four. The synchronous structure two includes a synchronous frame two fixed on the support frame between the telescopic rod two and the telescopic rod three, and a rotating shaft two rotatably connected to the synchronous frame two. A synchronous gear three and a synchronous gear four are fixed on the rotating shaft two. The synchronous gear three meshes with the rack three, and the synchronous gear four meshes with the rack four.

[0010] Furthermore, a synchronous opening five is provided on the other side of the outer tube three, and a rack five is provided on the sliding column three directly opposite the synchronous opening five. With the axis of the outer tube three as the center, the synchronous opening four and the synchronous opening five are at a 90-degree angle. A synchronous opening six is ​​provided on one side of the outer tube four, and a rack six is ​​provided on the sliding column four directly opposite the synchronous opening six. The synchronous structure three includes a synchronous frame three fixed on the support frame between the telescopic rod three and the telescopic rod four, and a rotating shaft three rotatably connected to the synchronous frame three. A synchronous gear five and a synchronous gear six are fixed on the rotating shaft three. The synchronous gear five meshes with the rack five, and the synchronous gear six meshes with the rack six.

[0011] Furthermore, a wedge-shaped fence is also provided on the rectangular platform.

[0012] The beneficial effects of this utility model are:

[0013] In practical applications, when the drive vehicle is parked beside the construction bridge, the piston rod of the hydraulic cylinder extends vertically downwards, causing the rectangular platform to gradually descend. Through the synchronous structures—one between telescopic rods one and two, another between telescopic rods two and three, and yet another between telescopic rods three and four—the telescopic rods one, two, three, and four are forced to extend and retract synchronously, resulting in a smoother descent of the rectangular platform and effectively reducing the significant swaying of the construction platform during lifting and lowering. This invention effectively reduces the significant swaying of the construction platform during lifting and lowering, preventing workers on the platform from experiencing fear and improving their work quality and efficiency.

[0019] In use, the drive vehicle 1 is parked beside the construction bridge. As the piston rod of the hydraulic cylinder 4 extends vertically downwards, the rectangular platform 2 gradually moves downwards. Through the synchronous structure one between telescopic rod 1 31 and telescopic rod 2 32, the synchronous structure two between telescopic rod 2 32 and telescopic rod 33, and the synchronous structure three between telescopic rod 33 and telescopic rod 4 34, the telescopic rods 1 31, 2 32, 3 33, and 4 34 are forced to extend and retract synchronously, thereby making the downward movement of the rectangular platform 2 more stable and effectively reducing the large-scale shaking of the construction platform during the lifting and lowering process.
