Special automatic circular pipe plasma cutting machine for expressway construction process and use method

Abstract

The invention relates to the technical field of mechanical equipment for expressway construction, and particularly relates to a special automatic circular pipe plasma cutting machine for an expresswayconstruction process and a use method. The machine is characterized in that a holding device is driven through a cylinder to hold and fix a circular pipe, thus the machine is applicable to circular pipes with different diameters; the circular pipe clamping pipe can be controlled by controlling air pressure, so that the problems that a thin circular pipe in cutting is pressed and deformed due to excessively high clamping force, the thin circular pipe cannot be tightly clamped due to excessively small clamping force, and the cutting process is dangerous, can be solved; a feeding device is arranged, so that the circular pipe feeding capacity is ensured, and quantitative cutting is realized; a supporting device is arranged, and the height of a supporting pulley can be automatically adjusted,and thus the circular pipe can be in a horizontal state during being cut; the overall fitting design realizes automatic cutting, and the circular pipe can be cut into different patterns; the working efficiency is high; and moreover, the safety in the construction process and the construction speed can be ensured.

Description

technical field [0001] The invention relates to the technical field of expressway construction machinery and equipment, in particular to a special round pipe plasma automatic cutting machine for expressway construction process and its use method. Background technique [0002] The Shihuang Expressway is an important part of the expressway planning network of "five vertical, six horizontal and seven lines" in Hebei Province. The construction of the key project Huanghua Comprehensive Port is the main artery to promote the economic development of the Bohai Rim Economic Zone and the central and southern regions. Huangshi Expressway starts from Huanghua Port in the east, connects with Shitai Expressway in the west, connects with Jingshi, Shi'an, Baocang, Beijing-Shanghai, Jinshan and other expressways, and ends in Shijiazhuang. Among them, the section from Shijiazhuang to Xinji was completed and opened to traffic in December 1998, the section from Xinji to Cangzhou was completed ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to aim at the above-mentioned technical deficiencies, and provide a special circular pipe plasma automatic cutting machine for expressway construction and its use method. The cylinder drives the clamping device to clamp and fix the circular tube tightly, adapting to different diameters. For round pipe, the clamping force of the round pipe can be controlled by controlling the air pressure, which solves the problem that when the thinner round pipe is cut, the round pipe will be deformed if the clamping force is too large, and the round pipe will not be clamped tightly when the clamping force is too small. Very dangerous problem; the setting of the feeding device can realize the feeding amount of the round tube and realize quantitative cutting; the setting of the supporting device can automatically adjust the height of the supporting pulley so that the round tube is in a horizontal state when cutting, and the overall matching design can realize automation Cutting, realize the cutting of different patterns of round pipes, high work efficiency, and in the process of high-speed construction, it has little impact on restricted traffic vehicles, ensuring the safety of construction and improving work efficiency
