Description

Technical Field

[0001] The utility model relates to a pipeline butt joint device and belongs to the technical field of pipeline connection. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, the fluid is pressurized by blowers, compressors, pumps and boilers, and then flows from the high-pressure part of the pipeline to the low-pressure part. The fluid can also be conveyed by its own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations.

[0003] The existing patent number is CN218118848U, which is a pipe docking device. This device is equipped with a turntable, a docking seat, and a clamping block. In order to facilitate the adjustment of the docking angle of the pipe fittings, the pipe fittings to be docked can be clamped between two corresponding clamping blocks on a plurality of docking seats, and then the two clamping blocks can be driven by a driving member to approach the pipe fittings, so that the pipe fittings are clamped between the two clamping blocks. Then, the first locking member for locking the moving block and the second locking member for locking the turntable can be released, so that the moving block can slide on the bar block, so that the two pipe fittings are close to each other. When docking, the turntable can be rotated on the moving block according to the actual situation, so as to adjust the docking angle of the pipe fittings. When the two pipe fittings are aligned, they can be The position of the turntable on the moving block is fixed by the second locking piece, so that the pipe fittings can be docked. However, this device requires manual clamping and docking of the pipes during the entire process of connecting the pipes, which increases the difficulty of operation and is prone to up and down tilting due to the weight on both sides of the pipes when the clamping blocks clamp the pipes, affecting normal docking. Moreover, during the docking process, although the angle can be adjusted, the positions of the pipes on both sides need to be manually adjusted during the docking process after the pipe angle is adjusted. Because the pipes have an inclination angle after the angle is adjusted, they need to be constantly approached during the docking process, and then the two-way positions need to be operated simultaneously, which is not convenient for direct docking and is not conducive to quick docking after the pipe angle is adjusted.
