Description

Technical Field

[0001] The utility model relates to the technical field of bridge frame installation, in particular to an auxiliary device for bridge frame installation. Background Art

[0002] Cable trays are categorized into trough-type, tray-type, ladder-type, and grid-type structures, and are composed of brackets, supports, and mounting accessories. They can be installed independently or on various buildings and pipe gallery supports, featuring simple structure, attractive appearance, flexible configuration, and easy maintenance. All parts must be galvanized. For cable trays installed outdoors near the sea or in corrosive areas, the material must be corrosion-resistant, moisture-resistant, have good adhesion, and possess high impact strength.

[0003] For example, Chinese patent: CN212543189U, the technical solution disclosed in this patent is as follows: a cable tray installation auxiliary device for power engineering is disclosed, which relates to the field of cable installation technology, including a vehicle body, a lifting structure, an isolation frame and a feeding structure. An isolation frame is vertically fixed at the center position of the top side of the vehicle body, and two groups of lifting structures are provided on the top side of the vehicle body. The two lifting structures are respectively located on both sides of the isolation frame, and the feeding structure is provided on one side of the lifting structure. By providing two groups of lifting structures, the output motor operates to drive the bidirectional screw to rotate, and the first slider and the second slider can be synchronously slid along the guide rail, which can realize the lifting of the support plate on one side of the isolation frame. The lifting structure on one side of the isolation frame achieves the purpose of supporting the bridge frame, and the lifting structure on the other side of the isolation frame lifts the bridge frame to a height parallel to the conveyor belt on one side of the isolation frame. The transmission operation of the two conveyor belts can realize stable transportation of materials, reduce manual material delivery, reduce labor consumption, and improve the efficiency of bridge frame installation.

[0004] However, in actual use, no blocking protection devices are set on both sides of the above-mentioned patented conveyor belt, and the bridge frame is mostly installed in an outdoor environment. Therefore, in harsh environments such as strong winds, the bridge frame at the upper end of the conveyor belt is at risk of falling, and the safety is poor. Utility Model Content
