Embodiment Construction

[0016] The present invention is not limited by the following implementation examples, and specific implementation manners can be determined according to the technical solutions of the present invention and actual conditions. Combine below figure 1 , figure 2 The present invention is described below. The positional relationship of up, down, left, right, etc. is based on the attached figure 1 determined by the layout direction.

[0017] The main body of the base 7 is cylindrical, the main body of the rotating sleeve 10 is cylindrical, the rotating sleeve 10 is set inside the base 7, and the sliding bearing 8 is arranged between the base 7 and the rotating sleeve 10 . A step is provided in the middle of the swivel sleeve 10, and the collar 9 cooperates with the step of the swivel sleeve 10 and axially fixes the swivel sleeve 10, and connects the collar 9 and the base 7 with bolts.

[0018] The pressing plate 14 is disc-shaped and arranged in the rotating sleeve 10 , and the ...

Abstract

The invention relates to an anti-eccentric tube cleaner. The anti-eccentric tube cleaner is used for tube construction such as tube cleaning, detecting and tube coating, and the problem of severe eccentric wear of an existing tube cleaner can be solved. According to the technical scheme, a rotating sleeve is inserted in a base, and is fixed on the base axially by a clamping ring, rubber cups are mounted at outer ends of the rotating sleeve, the center of the base is provided with a central gear and an edge gear and is fixed by a pressing plate, the edge gear is engaged with an inner gear ring of the rotating sleeve, the center gear is driven by a motor, the motor is fixed on the base through a support, a barrel and a rubber bowl are mounted at an end of the base, and a storage battery is arranged in the barrel. The anti-eccentric tube cleaner is compact in structure, small in length-to-diameter ratio and high in passing ability on parts such as a bent tube and an elbow; and speed is reduced by a planetary gear, reduction ratio is large, relative rotation speed of the rubber cups at the front end and the rear end of the tube cleaner is low, and the tube cleaner runs stably.

Description

technical field [0001] The invention relates to an anti-eccentric wear pipe pig, which is used for pipeline construction such as pipeline pigging, detection and pipeline coating. Background technique [0002] Pipelines that transport fluids such as oil, water, and gas for a long time will face problems such as blockage, corrosion, and scaling. Regular dredging and inspection of pipelines are required. Different types of pigs are used for pipeline pigging and in-pipe inspection. There are many types of pigs, namely mandrel pigs, foam pigs, and integrated pigs. (Solid-cast Pig) and spherical pig (Sphere Pig). All the above types of pigs work like a piston in the pipeline, advancing under the push of the medium in the pipeline, and complete the pigging, pipeline inspection, pipeline coating and other work. [0003] Due to the influence of its own weight, the cup at the lower end of the pig is severely worn. On the other hand, impurities in the pipe are deposited below, among...
