AI Technical Summary
Technical Problem
During the construction of existing thermal pipelines, the end face of the pipeline flange is worn, the rubber pads are damaged and leaked, and the pipeline docking is inaccurate, which affects the quality of the connection.
Method used
The guide docking mechanism is adopted to align the pipes by supporting the arc plate and positioning arc plate, push the latter pipe forward, align the flange screw holes to avoid direct contact adjustment, and combine the screw rod, roller and measuring ruler to improve the butt accuracy.
Benefits of technology
It reduces the risk of flange end face wear and rubber pad damage, reduces the probability of leakage, and improves the accuracy and installation efficiency of pipeline connections.

Abstract
The invention relates to the technical field of thermal engineering pipeline construction, in particular to a thermal engineering pipeline construction butt joint device which comprises two supporting parts and two mounting plates oppositely arranged in the radial direction of a pipeline, and the mounting plates are detachably connected with the supporting parts; a guide butt joint mechanism is arranged on the mounting plate and comprises a supporting arc plate located below the front side pipeline, at least two positioning arc plates located below the rear side pipeline and a support used for mounting the supporting arc plate and the positioning arc plates, and the supporting arc plate and the positioning arc plates are arranged in an aligned mode. The supporting arc plate is attached to the bottom side of the front pipeline, the positioning arc plate is attached to the surface of the rear pipeline, the supporting arc plate and the positioning arc plate are aligned front and back, the front pipeline and the rear pipeline are also aligned, the rear pipeline is pushed forwards, the pipelines are rotated after butt joint, flange screw holes are aligned, and the front pipeline and the rear pipeline are installed well. The abrasion of the end faces of the flanges, the damage and leakage risks of the rubber pads and the collision between the two pipelines are reduced, and the connecting precision between the pipelines is improved.
