Abstract
Description
Technical Field
[0001] This application relates to the technical field of pipeline cleaning brushes, and particularly to a detachable cleaning brush for pipelines. Background Art
[0002] After a pipeline such as a copper pipe or a steel pipe is placed in the air for a period of time, a chemical reaction will occur between its surface and substances such as moisture and oxygen in the air, forming a layer of rust. When processing the pipeline, it needs to be cut and welded and applied to the required buildings or other equipment. Before welding, it is necessary to clean the rust or burrs on the outer side wall of the pipeline end, so as to ensure the welding effect.
[0003] The traditional cleaning brush has a cylindrical structure, and the bristles are fixedly arranged on the inner wall of the sleeve. The sleeve is sleeved on the pipeline end, and the sleeve is rotated to clean the rust or burrs. The structure design is simple and the cleaning can be completed quickly. However, there are still certain drawbacks in the use of the traditional cleaning brush. During the repeated cleaning process, the cleaning bristles will be worn. Once the wear is serious, it will affect the cleaning effect. The traditional cleaning brush needs to replace the entire sleeve, and its replacement cost is high. In view of this, this application proposes a detachable cleaning brush for pipelines. Utility Model Content

[0029] Embodiment
[0030] As Figures 1-4 shown, the detachable cleaning brush for pipelines proposed in the present application includes a sleeve 1 and a driving rod 2 connected to the end of the sleeve 1. The driving rod 2 is a multi-sided column and is used to be inserted and matched with the end of an external pistol drill to drive the pistol drill to complete the rotation of the driving rod 2 and the sleeve 1. A cleaning brush piece 3 is arranged inside the sleeve 1, and the cleaning brush piece 3 is arranged in an arc shape and fits on the inner wall of the sleeve 1. A pin 6 for circumferentially positioning the cleaning brush piece 3 is arranged on the side wall of the sleeve 1 to prevent the cleaning brush piece 3 from rotating and shaking inside the sleeve 1 during the rotation cleaning.
[0031] Among them, a positioning head 4 is detachably arranged at the end of the sleeve 1 away from the driving rod 2 for positioning the end of the cleaning brush piece 3, and when the connecting cylinder 42 is unscrewed, it is convenient to remove the cleaning brush piece 3 to one side for replacing the cleaning brush piece 3.
[0032] Specifically, the cleaning brush piece 3 is made of plastic and is bent and fitted to the inner wall of the sleeve 1. The inner wall of the cleaning brush piece 3 is provided with bristles 31; the bristles 31 are vertical or bent. When the bristles 31 are at the end of the pipeline to be cleaned, they can fully contact the side wall of the end of the pipeline.
[0033] Further, the positioning head 4 includes a support ring 41 fixedly connected to the end of the sleeve 1. A connecting cylinder 42 is sleeved on the side wall of the support ring 41. A channel 43 is opened on the end face of the connecting cylinder 42. When the connecting cylinder 42 covers the end of the support ring 41, the bristles 31 protrude into the inner side of the channel 43. The inner diameter of the channel 43 is larger than the outer diameter of the pipeline, so that the sleeve 1 can be sleeved on the side wall of the end of the pipeline; wherein, an external thread is provided on the outer side wall of the support ring 41, and an internal thread matching the external thread is provided on the inner wall of the connecting cylinder 42. The threaded connection method is simple and convenient to operate.
[0034] It should be noted that a plurality of through holes 5 are opened on the side wall of the sleeve 1. Preferably, there are two through holes 5. The pin 6 is inserted into the through hole 5, and the inner end of the pin 6 protrudes into the inside of the sleeve 1. When the cleaning brush piece 3 is fitted to the inner wall of the sleeve 1, there is a distance between the two end parts of the cleaning brush piece 3. A plurality of pins 6 are located within the distance, and the end parts of the cleaning brush piece 3 are positioned by the pins 6.
[0035] The working principle of this embodiment is as follows: When using this cleaning brush, insert the driving rod 2 into the output end of the pistol drill, then sleeved the positioning head 4 on the end of the cut pipeline (the pipeline can be a steel pipe, a copper pipe, etc.), and then start the pistol drill to drive the driving rod 2 to rotate. Further, the sleeve 1 and the cleaning brush piece 3 are driven to rotate by the driving rod 2 to clean the rust and burrs at the end of the pipeline, so that the end of the pipeline has good cleanliness, which is beneficial to the smooth progress of welding. When the bristles 31 are severely worn and need to be replaced, rotate the connecting cylinder 42, unscrew the connecting cylinder 42, and then take out the worn cleaning brush piece 3. Bend the new cleaning brush piece 3 into an arc shape and fit it to the inner wall of the sleeve 1. When installing the cleaning brush piece 3, it should be noted that the two ends of the cleaning brush piece 3 are respectively located on both sides of a plurality of pins 6. The pins 6 play a guiding role in the circumferential direction of the cleaning brush piece 3 to prevent the cleaning brush piece 3 from rotating by itself during the rotary cleaning. After the cleaning brush piece 3 is installed, then tighten the connecting cylinder 42 on the side wall of the support ring 41. The operation is simple and fast, and the replacement of the cleaning brush piece 3 can be quickly completed; the replacement cost is low, and it is environmentally friendly and practical.
[0036] The above specific embodiments are only the preferred embodiments of the present application. Based on the technical solution of the present application and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments; the above specific embodiments are only explanations of the present application, and they do not limit the present application.
