Description

TECHNICAL FIELD

[0001] The utility model relates to gas pipeline processing technical field especially relates to a gas pipeline bending device. BACKGROUND

[0002] The gas pipeline is a pipeline system for conveying gas, which is usually composed of pipe materials, pipe fittings, valves and the like, and is widely used in fields such as families, businesses and industries to ensure that gas can be safely and stably conveyed to various gas-using equipment. In the actual installation environment, the gas pipeline needs to be laid according to the structure of the building, the layout of the room and the position of the gas-using equipment. Therefore, the bending device needs to be used for bending treatment. Thus, it can bypass obstacles such as corners, beams and columns, and thus better adapt to complex space environments, realize reasonable routing planning and ensure that gas can be accurately conveyed to the required place.

[0003] In the existing gas pipeline bending device, the overall structure usually presents a relatively fixed form. This means that the connection between components is mostly by welding, one-piece forming or using a complex and difficult-to-disassemble fastening method. For example, the key components of some devices are tightly fixed by large bolts, the number of bolts is large and the position is difficult to access, or the components are directly welded into one whole, which cannot be disassembled at all. Such disassembly difficulty seriously affects the maintainability of the device. When the device needs to be repaired due to failure, the maintenance personnel cannot quickly locate and replace the damaged components, greatly increasing the repair time and cost. When the device needs to be upgraded to adapt to new gas pipeline specifications or process requirements, due to the difficulty of disassembly, it is extremely difficult to add new components or replace old components, hindering the update and progress of technology. At the same time, in actual use scenarios, the device may need to be moved for operation at different locations, but the fixed overall structure and difficult-to-disassemble components result in a large device size and concentrated weight, which is extremely inconvenient for carrying and limits its application in complex working environments.
