Metallurgy clamping pipe welding fixing device

Abstract

The invention relates to the technical field of metallurgy tools, in particular to a metallurgy clamping pipe welding fixing device. The device comprises a pipe wrench frame and a guide column runninginto the pipe wrench frame. At least one set of clamping assemblies are installed on the guide column. Supporting pieces matched with the clamping assemblies are arranged on the guide column; according to the metallurgy clamping pipe welding fixing device, by arranging a plurality of clamping assemblies controlled by a hydraulic cylinder to be clamped, pipeline connectors are synchronously clamped and fixed conveniently, welding is facilitated, and the welding line alignment tolerance is lowered. By arranging a supporting assembly, the device can fix pipelines of different sizes by adjustingthe length of the supporting assembly on the condition that the clamping range of the clamping assemblies is determined. By arranging positioning pieces on the clamping assemblies, after the pipelineis preliminarily fixed, the clamping assemblies are locked through the positioning pieces, and the phenomenon that the clamping assemblies are loosened due to fatigue of the hydraulic cylinder and therefore pipeline assembling failure is caused is avoided.

Problems solved by technology

[0002] Industrial production, especially the metallurgical industry, consumes a lot of water. From the current point of view, most of my country's metallurgical industry production enterprises use a circular water supply system. This type of water supply system is convenient, efficient, and easy to handle. characteristics, but the main problem is small water point and large water supply

The circulating water supply system is simple in structure, and the water supply method adopted in use is one pump and one machine, and the overall water supply method is single

The circulating water supply system used by some metallurgical enterprises in the production process only has a single water supply equipment. Therefore, when carrying out metallurgical operations, there are many water points but small water consumption, which is difficult to meet the basic production needs.

In addition, the metallurgical industry water has certain water safety requirements, but the enterprise adopts this water supply design, the overall water supply method is single, and the equipment performance is not complete, which is prone to failure problems in the production process

Outdoor metallurgical pipelines are difficult to be transported to the construction site as a whole. Generally, they are connected by welding after section transportation. When welding in the field, there are many influencing factors. Uniform, prone to stress corrosion, resulting in leakage of the pipeline over a long period of use
