Box culvert transport vehicle and box culvert construction method

Abstract

The invention relates to a box culvert transport vehicle which comprises a vehicle frame and a walking system. The walking system comprises multiple independent suspension mechanisms. Each independentsuspension mechanism comprises a suspension drive component. A supporting system is arranged above the vehicle frame and comprises a cushion block and a cushion block adjusting component. A box culvert construction method includes the steps that the independent suspension mechanisms are lifted, enter a culvert and fall to the inner wall of the culvert; the lifted independent suspension mechanismsfall to the ground after traveling into the culvert, the height of the cushion block is increased, a box culvert is transported to an assembling position, the independent suspension mechanisms are lifted, travel into a culvert of a former box culvert and fall to the inner wall of the culvert of the former box culvert; the independent suspension mechanisms are adjusted when traveling to the matched positions; and the vehicle travels out, and the lifted independent suspension mechanisms fall to the ground. The box culvert transport vehicle is safe, reliable, free of congestion and beneficial toenvironment protection, the vehicle is barely influenced by weather, operation efficiency is high, and construction and operation are convenient.

Description

technical field [0001] The invention relates to a transport vehicle, in particular to a box culvert transport vehicle and a box culvert construction method. Background technique [0002] At present, the conventional prefabricated box culvert is installed by a truck crane. The operation method is: the truck crane is supported on one side of the groove of the box culvert, and the box culvert placed on the flatbed or on the ground is hoisted, and then rotated to lift the box culvert. The box culvert is hoisted to the predetermined installation position by arm and other operations. For accurate positioning, 4 people are required to hold crowbars at the four foot points in the box culvert for positioning, 2 people are required to control the width of the joints on both sides, and 2 people are arranged to dismantle the top. Install the sling and limit the top seam width. This method of hoisting has many disadvantages, including: [0003] 1. When the box culvert is accurately pos...

AI Technical Summary

Problems solved by technology

[0003] 1. When the box culvert is accurately positioned, the installation workers are located near the bottom of the boom, and there are great safety hazards in the installation operation;

[0004] 2. Because the car crane is usually placed on the road, it will cause traffic congestion and affect the normal traffic order;

[0005] 3. When there are green belts on both sides of the ditch, sometimes it is necessary to cut down trees due to the rotation and lifting of the boom, which will damage the ecological environment;

[0006] 4. When there is a high-voltage line next to the road trench, the hoisting operation sometimes cannot be operated;

[0007] 5. It is greatly affected by the weather. When encountering extreme weather such as strong winds, the operation safety hazard is great or the operation cannot be performed;
