Embodiment Construction
[0020] In order to fully understand the purpose, features and effects of the present invention, the present invention will be described in detail through the following specific embodiments, but the present invention is not limited thereto.
[0021] see figure 1 and figure 2 , a fixing device for the paired connection of pipelines provided by the present invention is composed of an arc hoop 1, a rotating shaft 4, an insertion rod 6 and an adjusting bolt 3, etc., the arc hoop 1 is a semicircular plate structure, two The arc hoop 1 constitutes a positioning tube structure. The two edges of the side wall of the arc hoop 1 are respectively fixed with rings 5, and the rotating shaft 4 is set in the ring 5 on one side, which is used to fix the two arc hoops 1 to rotate and open; the insertion rod 6 is inserted into the ring 5 on the other side , the pipeline 7 is temporarily fixed. Nut rings 2 are uniformly distributed on the upper and / or lower end faces of the arc-shaped hoop 1 ...

The invention discloses a fixing device for pipeline butt joint pairing connection and a pipeline butt joint method, and relates to the technical field of pipeline butt joint. The fixing device for pipeline butt joint pairing connection comprises arc-shaped hoops, rotating shafts, inserting rods and adjusting bolts, and the arc-shaped hoops are of a semi-circular plate structure. Circular rings are fixed to the two edges of the side wall of each arc-shaped hoop correspondingly, the rotating shafts are sleeved with the circular rings on one sides, the inserting rods are inserted into the circular rings on the other sides, and every two arc-shaped hoops form one positioning pipe. The two ends of one rotating shaft are sleeved with the positioning pipes correspondingly, and the two positioning pipes are connected through turn buckles. Nut rings are evenly distributed on the upper end face and / or the lower end face of each arc-shaped hoop in the circumferential direction, and the adjusting bolts penetrate through the nut rings to abut against the outer walls of pipelines. The device has the beneficial effects that the device is small in shape and easy to manufacture; the operation is convenient and fast, and the butt joint quality is good; the centering precision is high, and the speed is high; the operation space is not limited, the efficiency is high, and the application range is wide; and a high-altitude operation platform does not need to be erected, the construction cost is low, and potential safety hazards are avoided.
Description
technical field [0001] The invention relates to the technical field of pipe butt jointing, in particular to a fixing device and a pipe butt joint method for pipe butt joint connection. Background technique [0002] In the prior art, the pipeline welding construction method mainly includes: manually moving and combining the two pipelines, and assisting in jacking up and adjusting around the pipelines through jacks. Liner and other working space. The above matching method has limitations: (1) Inconvenient operation, difficult to control the matching quality; (2) Repeated manual movement, low alignment accuracy; (3) High-altitude platform pairing, great safety hazards; (4) High-altitude platform operation is cumbersome , The construction cost is high. Contents of the invention [0003] In order to solve the technical problems of inconvenient operation, low precision, difficult control, difficult assembly at high altitude, low efficiency, large safety hazards, and high const...
