Description

[Technical field]

[0001] The present invention relates to the technical field of bridge construction, and more particularly to a lifting platform for bridge construction. [Background technology]

[0002] In the bridge construction process, lifting operation is an extremely important part, which is directly related to construction efficiency and safety. In traditional lifting operation, the stable support of the weight block is a big challenge. The weight block is used to balance the moment of the lifting machine and ensure stability and safety during the lifting process.

[0003] However, in conventional lifting systems, the weight block is often fixed directly to the lifting machine, which lacks a flexible support structure, and during the lifting process, especially when the lifting machine rotates, the weight block is prone to shaking due to inertia, which not only affects the construction accuracy but also may cause safety hazards. Therefore, we have made improvements to this and proposed a lifting platform for bridge construction. Summary of the Invention [Means for solving the problem]

[0025] It should be noted that like symbols and letters represent like items in successive figures, so that once an item is defined in one figure, it need not be further defined and interpreted in subsequent figures.

[0026] Example 1 1 to 4, the bridge construction lifting platform includes a base 1, a rotary table 101 is rotatably mounted on the base 1, and a lifting machine body 2 is mounted on the top of the rotary table 101. Two weight support frames 3 are further fixedly attached to the top of the rotating table 101, a support plate 4 is fixedly attached to the top of the two weight support frames 3, and a weight assembly is provided on the support plate 4. A circular guide rail 301 is fixedly attached to the top of the base 1, and the circular guide rail 301 is provided with the rotating table as its center. A slide sheet 302 is slidably connected to the outer surface of the circular guide rail 301, and the slide sheet 302 is fixedly attached between the bottoms of the two weight support frames 3. In the present application, the circular guide rail 301 is installed on the base 1, and the slide sheet 302 is attached to the circular guide rail 301 to support the weight support frame 3 and further support the weight assembly, thereby realizing dynamic stable support of the weight assembly when the lifting machine body 2 rotates, greatly reducing the sway of the weight assembly, and improving the stability of the entire lifting platform.
