Description

Technical Field

[0001] The invention belongs to the technical field of bridge frames, and in particular relates to a multi-module spliced ​​bridge frame quick installation auxiliary device. Background Art

[0002] In order to protect power cables, communication equipment, pipelines and other lines, and to ensure that the laying of the lines does not affect people's passage or occupy the ground, a bridge is set outside the line so that the line can be installed through the bridge. In order to improve the flexibility of the bridge, the current bridge often adopts a modular design, and the bridge is spliced ​​and assembled. The current modular cable bridge is mainly divided into a trough structure, a ladder structure and a grid structure. In the splicing process of the cable bridge, riveting, threaded connection and welding connection are mostly used.

[0003] The trough-type bridge has neat wiring and carries fewer cables, making it easier to arrange. Therefore, it is widely used. At present, modular trough-type bridge splicing installation often uses expansion joints to adapt to the length and other requirements of the installation location, and the bridge is fixed at the installation location by bolts. Figure 1 As shown in the figure, a trough-type bridge module includes two bridge bodies 1 and telescopic parts 2. At least two pairs of adjusting grooves 3 are symmetrically arranged on the left and right sides of the telescopic parts 2. Installation slots are also arranged on the left and right sides of the bridge body 1 at the positions corresponding to the adjusting grooves. After determining the length, the installation and length fixation between the bridge body and the telescopic parts can be achieved by tightening the bolts through the adjusting grooves and the installation slots on the corresponding sides.
