AI Technical Summary

Technical Problem

In the prior art, temporary support is required due to bumps and squeezing during transportation of steel box beams, but the welded steel support rods are prone to damage the steel box beams when removed, increasing the workload of later repairs.

Method used

A temporary support device is designed, including a sleeve, a telescopic member and a support plate. The support force is adjusted through the sleeve and a telescopic member. The support plate is topped on the sleeper to achieve stable support for the steel box girder and to release the support without cutting after arriving at the transportation site.

Benefits of technology

It effectively prevents damage caused by the removal of support rods during transportation, reduces the workload of later repairs, and simplifies the installation and disassembly of support devices.

Abstract

The utility model relates to the technical field of steel box girder transportation, and particularly discloses a temporary supporting device for steel box girder transportation. The device comprises a device body, the device body comprises a sleeve, and telescopic pieces are arranged at the two ends of the sleeve; the telescopic piece comprises a threaded rod extending into the sleeve, and an inner thread matched with the threaded rod is arranged on the inner side wall of the sleeve. Supporting plates are arranged at the ends, away from the sleeves, of the threaded rods. The problem that the steel box girder is prone to being damaged when the supporting rod and the steel box girder are welded and detached can be solved, and the effects of preventing the steel box girder from being damaged and reducing the later repair workload are achieved.
