Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction platforms, in particular to a trackless bridge inspection and construction platform. Background Art

[0002] The inspection work at the bottom of the bridge is often carried out by using equipment such as shovels, forklifts and cranes to raise inspectors from the ground to the bottom of the beam for visual observation; while the repair and reinforcement of the bottom of such bridges requires the erection of a full-bridge scaffolding. The cap beam construction platform is a temporary platform facility commonly seen in large bridges, elevated roads, buildings and other projects. It provides a safe and stable working space for construction workers and promotes the smooth casting, installation and adjustment of the beam body.

[0003] A Chinese patent with publication number CN204212054U discloses a movable row-type flexible pier continuous beam bridge bottom inspection and construction work platform, including no less than two pairs of hoops fixed on the piers of two rows of adjacent bridge piers in a pairwise manner, a walking track installed on the hoops and a work platform arranged on the walking track; the hoops include two track-receiving beams arranged on both sides of the bridge pier body; the walking track is provided with no less than two rail-receiving beams, which are respectively fixed on the track-receiving beams on the piers of two rows of adjacent bridge piers by a track fixing structure, and the walking track is arranged along the transverse direction of the bridge; the lower ends of both sides of the work platform are slidably connected to the walking track. The platform designed by the utility model has a simple structure, strong practicality, high reliability, and has both inspection and construction functions.

[0004] In the current existing technology, for areas that cannot be reached by the bottom beam inspection trolley, aerial platforms, cranes and hangers are generally used as construction platforms. When aerial platforms or cranes are used as construction platforms, they have a greater impact on the driving under the bridge and pose a great safety risk. Each construction area is small, and the aerial platforms or cranes need to be moved frequently, which also has a certain impact on the construction quality. The hanger method requires high-altitude erection, which is risky during the erection process and requires hanging points to be made on the original structure, which causes certain damage to the original structure, making it impossible to extend or lengthen the construction platform without moving it, and thus to inspect bridges at different locations.

[0005] To this end, the utility model provides a trackless bridge inspection construction platform. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.
