Description

Technical Field

[0001] The utility model relates to the technical field of oil fields, in particular to a pig ball launching device for long-distance gathering and transportation pipelines in oil fields. Background Art

[0002] During the transportation process of some gathering and transportation pipelines, due to the low temperature or the large amount of oil impurities, it is easy to adhere to the inner wall of the pipeline. Therefore, it is necessary to clean the inner wall of the gathering and transportation pipeline. In the existing impurity cleaning device, the cleaning ball needs to be put into the inner wall of the launch device before launching, and then it is launched by pressure.

[0003] China Patent Network has published a pipe cleaning ball launching device for long-distance oilfield gathering and transportation pipelines, with publication number CN219943981U, which relates to the field of oilfield transportation technology. In view of the problems that the existing pipe cleaning balls are inconvenient to manually put in and the transportation of the pipe cleaning balls is troublesome after cleaning, the following solution is proposed, which includes a launching tube, one end of the launching tube and the circumferential side wall are provided with a support frame, the end of the support frame is provided with an introduction structure for the introduction of the pipe cleaning ball, and the introduction port of the launching tube is provided with a transportation structure for carrying the pipe cleaning ball; the introduction structure includes a servo motor, a driving gear, a driven gear, a rotating gear, a screw rod, a limit rod, a slide, a connecting rod and a guide block. The utility model of the pipe cleaning ball launching device for long-distance oilfield gathering and transportation pipelines does not require manual transportation of the pipe cleaning ball to the launch tube port, making the transportation of the pipe cleaning ball simpler, and also does not require manual introduction of the pipe cleaning ball into the launching tube, making the launching of the pipe cleaning ball more convenient;

[0004] The above-mentioned device controls the guide block to move toward one side of the launch device when pushing the pipe cleaning ball into the launch device. The guide block can push the pipe cleaning ball into the launch device during movement. However, the contact between the guide block and the surface of the pipe cleaning ball is hard, and the surface of the pipe cleaning ball will be damaged after long-term use, thereby affecting its cleaning effect. Therefore, a pipe cleaning ball launching device for long-distance oilfield gathering and transportation pipelines is proposed. Utility Model Content
