Tunnel large caliber steel tube conveyor system

Abstract

The invention discloses a channel large-diameter steel pipe delivery device which belongs to the vehicle body structure with self-unloading function for carrying oblong goods. A direct current motor,a reducer, a clutch, a transmission turning device of a driving part of the delivery device are arranged at the rear of a vehicle frame; an active walking wheel of a walking part of the delivery device is arranged at the half part of the back of the vehicle frame; a driven walking wheel is arranged at the front end part of the vehicle frame; a steering part of the delivery device is arranged at the front end part of the vehicle frame; the front stinger and the back stinger of a bearing part of the delivery device and the front hydraulic ram and the back hydraulic ram of an unloading part of the delivery device are respectively arranged right above the driven walking wheel and the active walking wheel; a direct current power supply of the delivery device is arranged at the middle part of the vehicle frame; an electric control box of an electric control part of the delivery device is arranged at the back end part of the vehicle frame; an operation control box is held by operators by hand. The device is specially applied to transporting the steel pipe into the channel when the large-diameter steel pipe road is paved, can automatically unload and pave the pipe, has the high automationperformance, the non-channel operation, the adjustable steering, the safety and reliability without causing noises and can easily pass by the winding segments of the channel. The device is the electromechanical integrated channel delivery device of the pipeline construction with the independent innovation.

Description

(1) Technical field [0001] The invention relates to a trackless vehicle for transporting special objects, such as a body structure for carrying elongated goods and having a self-unloading function. Specifically, it is a tunnel large-caliber steel pipe conveying device. (2) Background technology [0002] my country's West-East Gas Pipeline and Sichuan-East Gas Pipeline natural gas pipeline laying projects are unprecedented in the history of domestic pipeline engineering for their large diameter, long distance, and high construction difficulty. The diameter of the steel pipes is more than 1 meter, and the distance is thousands of kilometers, especially in the central and western regions, where there are thousands of mountains and valleys, and the terrain is very complex, so the construction difficulty can be imagined. According to the design requirements, tunnels shall be excavated in the mountainous areas where the gas transmission pipeline passes, and pipe piers shall be se...

AI Technical Summary

Problems solved by technology

Its advantage is that steel wheels are replaced by rubber wheels, which overcomes the disadvantage of noise, and it is trackless, flexible and easy to adjust to bends; but its disadvantage is that the pipe transport vehicle is manually drawn, and the steering is completely controlled manually, which is labor-intensive and not safe enough. , still cannot automatically unload and arrange pipes, only small-diameter steel pipes can be transported
