Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction tools, in particular to an adjusting device for bridge hoisting. Background Art

[0002] A bridge generally refers to a building erected over rivers, lakes, or the sea to enable vehicles and pedestrians to pass smoothly. To adapt to the modern, rapidly developing transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology, or meet other transportation needs to make travel more convenient. In particular, high-speed rail lines in railway transportation all use prefabricated bridge construction. The abutments, piers, and foundations are cast within the planned route, and then the prefabricated box-type bridges are hoisted and laid in the factory, which greatly reduces the construction period. However, when hoisting prefabricated bridges, the steel wire ropes used in the hoisting equipment need to be stabilized with auxiliary hoisting equipment to maintain the stability of the hoisting process.

[0003] The utility model document with application patent number CN202022245971.6 discloses an adjusting device for lifting an assembled bridge, which belongs to the technical field of bridge construction equipment, including a first crossbeam, a second crossbeam, a first diagonal rod, a first vertical rod, a hoist and a moving mechanism. The number of the first crossbeams is two, and the number of the second crossbeams is two. One second crossbeam is fixedly connected to one end of a pair of first crossbeams, and the other second crossbeam is fixedly connected to the other end of the pair of first crossbeams. The first vertical rod is fixedly connected to the bottom end of the second crossbeam. A distribution box is fixedly connected to the first crossbeam. The number of the moving mechanisms is two, and the moving mechanism is slidably connected to the first crossbeam; the moving mechanism includes a first fixed frame, a second fixed frame, a second connecting plate, a first guide wheel, a second guide wheel, a third guide wheel, a connecting piece and a first motor; the utility model can stably adjust the position of the assembled bridge during lifting, so as to facilitate the quick docking of the ends of the assembled bridge.
