An auxiliary device for transporting large-scale drainage steel pipes for construction sites

Abstract

The invention belongs to the technical field of pipeline transportation, in particular to an auxiliary device for transportation of large-scale drainage steel pipes for construction sites. Aiming at the problem in the prior art that the steel pipes are rigidly bolted during the process of transporting steel pipes, the collapse can not be predicted before the collapse, the following proposals are proposed, including Two load-bearing boxes fixed on the upper surface of the flatbed car base are symmetrical to each other, and the upper surface of the two load-bearing boxes is reserved near the middle with an arc-shaped surface. The diameter of the arc-shaped surface is the same as the diameter of the steel pipe. There are round holes near the top. The present invention can be used when the steel pipe is deflected to one side too much during transportation, and the jacking column will drive the jacking pipe to slide upwards obliquely under the action of the return spring 2, and at this time, different metal sheets will be driven to match with each other in turn. The contact slide bar contacts to switch on different alarm circuits, thereby sending out different alarms.

Description

An auxiliary device for transporting large-scale drainage steel pipes for construction sites technical field The present invention relates to pipeline transportation technical field, relate in particular to a kind of auxiliary equipment for large-scale drainage steel pipe transportation for construction sites set. Background technique Existing steel pipe construction site is transferred to factory and transport in the hole, mostly adopts transport trailer or rented special vehicle to carry out, but When transporting large diameter and heavy steel pipes, there is a great risk. Generally, the width of transport vehicles is between 2 meters and 3 meters. Steel pipes with a diameter of more than 9 meters, such as steel pipes of more than 9 meters, are transported by conventional vehicles, and one end needs to be overhanging more than 3 meters, which can be transported on flat roads. If it needs to be transported under the conditions of steep slopes, many turns and uneven...
