Central air conditioning pipeline welding auxiliary device for building construction

Abstract

The invention discloses a central air conditioning pipeline welding auxiliary device for building construction. The device comprises a base and a rotating platform; the base is arranged horizontally;a driving assembly is vertically fixed to the top surface of the base; the rotating platform capable of rotating horizontally is horizontally fixed to the top end of the driving assembly; and a conical block is coaxially fixed to the middle of the rotating platform. The device has the beneficial effects that a copper pipe is vertically arranged on the conical block in a sleeving manner, then the rotating platform can drive the copper pipe to rotate at a constant speed for welding, the manner that a worker holds the copper pipe for rotation is replaced, thus the working intensity of the workeris reduced, and the welding efficiency can be improved; the vertical copper pipe is clamped in such a manner that arc-shaped clamping plates of multiple clamping assemblies get close to one another, the vertical state of the copper pipe is kept, the situation that the copper pipe bounces in the radial direction in the rotating process is prevented, dislocation at the welding joint of the copper pipe is avoided, and the welding quality can be improved.

[0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. , people usually install central air-conditioning systems in large buildings. The central air-conditioning system is composed of one or more cold and heat source systems and multiple air-conditioning systems. The principle of liquid vaporization refrigeration is used to provide the required cooling capacity for the air-conditioning system. , to offset the cooling load of the indoor environment. The heating system provides the required heat for the air conditioning system to offset the heat load of the indoor environment. When welding some copper pipes with larger diameters, the installation workers will weld the copper pipes on the ground first, and then pass through the wall. When welding copper pipes with larger diameters, Usually, one person is required to hold the copper pipe, and the copper pipe needs to be rotated at a uniform speed during welding, and the other person is responsible for welding, which not only takes time and effort, but also leads to low welding efficiency. At the same time, it is inevitable that the radial runout of the copper pipe will occur during the process of rotating the copper pipe. , resulting in misalignment of the welded joints of the copper pipes, which directly reduces the welding quality
