[0022] like Figures 1 to 5As shown, a mobile work platform for the reinforcement construction of the inner top plate of a concrete box girder includes an adjustment component, a sliding device, a truss component and a platform component. The sliding device, the truss component and the platform component are arranged in sequence from top to bottom between four groups of adjustment components. The truss component includes a main truss 11 and a truss diagonal brace 21. The main truss 11 is horizontally arranged between the four groups of adjustment components in a frame structure. The two adjacent side frames of the main truss 11 are connected by a truss diagonal brace 21. The platform component includes a grating support frame 7 and a fence 18. The grating support frame 7 is horizontally arranged above the main truss 11, and the fence 18 is horizontally arranged above the grating support frame 7.

It can also adapt to the unevenness of the bottom plate and has high applicability, making this working platform highly applicable and versatile. This working platform has a simple structure, is easy to build, and is safe to construct. It can also meet the needs of different beam height changes.

[0024] In this embodiment, the adjustment assembly includes an upper adjustment pin 6, an upper vertical rod 22 and a lower vertical rod 23 that are mutually connected. The upper vertical rod 22 and the lower vertical rod 23 are each provided with a corresponding upper height adjustment hole 5 at one end thereof that is close to each other. The upper adjustment pin 6 is disposed in the upper height adjustment hole 5. The grating support frame 7 and the fence 18 are connected to the upper vertical rod 22.

[0025] In this embodiment, the sliding device includes a connecting rod 1 and a pulley 10. The connecting rod 1 is sleeved with the end of the lower vertical rod 23 away from the rod 22. The ends of the connecting rod 1 and the lower vertical rod 23 that are closer to each other are each provided with a corresponding lower height adjustment hole 13. A lower adjustment pin 19 is disposed within the lower height adjustment hole 13. The main truss 11 is connected to the lower vertical rod 23.

This structure mainly plays the role of temporary support to improve the activity stability and overturning stability of the working platform, so that the web supports 15 and chamfer supports 14 are temporarily connected to the concrete box girder, and the bottom plate support 12 is against the ground. The working platform is temporarily fixed to carry out the work of repairing and reinforcing the top plate of the concrete box girder. When one reinforcement task is completed, the fixation is released, and after moving to the next position, it is temporarily fixed again until the work of the entire bridge is completed.
