Problems solved by technology

[0002] For the erection of existing high-speed railway passenger dedicated line bridges, the girder manufacturing process cannot complete the overall prefabrication of the shutters. This is because if the overall prefabrication requires high prefabricated templates for the bridge, this will lead to irregular geometric shapes of the beams. To increase the difficulty of bridge construction, we adopt the technology of shutter construction after the completion of girder erection. Since the outer part of the shutter is located at the outer end of the bridge, it belongs to high-altitude cantilever construction. The construction technology is difficult, the safety factor is low, and the project quality is difficult to guarantee. , the overall line shape of the shutter directly affects the appearance quality and construction progress of the subsequent steel railing installation. The number of construction bridges is large, and the span of a single bridge is large. Therefore, how to shorten the construction cycle, reduce the input of human resources, and reduce construction costs , improving the quality of the project has become the biggest problem encountered in the shutter construction

Embodiment 1

[0025] Embodiment 1: as Figure 1 to Figure 7 As shown, the specific scheme of the first embodiment of the present invention is provided in detail, and the first main purpose of the present invention can be realized. The scheme includes a running device 1 installed on the beam surface 71 of the bridge 7, a supporting frame 2 located on the upper part of the running device 1 and connected thereto, an anti-hung running device 3 located inside the supporting frame 2 and connected thereto, and an anti-hung walking device. Device 3 is the embodiment of the counterweight balancing device in this embodiment, and is positioned at the outside of the support frame 2 and is movably connected with the shutter cavity 4; the above-mentioned parts are formed with the walking device 1 as the fulcrum, the support frame 2 as the lever, and the shutter cavity 4. The plate cavity 4 and the anti-hanging running device 3 are lever mechanisms with loads at both ends. In this lever mechanism, the shr...

Embodiment 2

[0030] Embodiment 2: as Figure 8 to Figure 14 As shown, the specific scheme of the second embodiment of the present invention is provided in detail, and the second main purpose can be realized while realizing the first main purpose of the present invention, that is, when the shutter 72 is cast-in-place, synchronously Carry out the cast-in-place construction of the first cable duct vertical wall 73, the second cable duct vertical wall 74 and the slag retaining wall 75. The difference between this solution and Example 1 is that the counterweight balance device no longer uses the anti-hanging walking device 3, but uses two sets of vertical wall cavity 8 of the cable groove suspended under the supporting frame 2, and the inner side of the supporting frame 2. A set of slag retaining groove cavity 9 and another traveling device 1 are the specific performance of the counterweight balancing device of this embodiment. The cavity 8 of the vertical wall of the cable trough is suspended...
