Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage pipe processing technology, specifically a polishing device for drainage pipe production. Background Technology
[0002] As is well known, drainage pipes, as a core component of urban infrastructure and building drainage systems, are responsible for the collection and discharge of rainwater and sewage. The smoothness of their inner walls directly affects drainage efficiency and system lifespan. With the diversification of building designs and the refinement of municipal engineering, drainage pipe specifications are becoming increasingly diverse, especially pipes with different inner diameters, which are widely used in practical projects. From small-diameter sewage pipes in civil buildings to large-diameter drainage pipes in municipal engineering, their inner diameters can range from 50mm to 2000mm. This difference in specifications places higher demands on the polishing treatment of the drainage pipe's inner wall.
[0003] Currently, the industry commonly uses a polishing wheel in conjunction with a drive motor to polish the inner wall of drain pipes. For drain pipes of different inner diameters, it is necessary to frequently change polishing wheels of the appropriate size to ensure polishing effectiveness. However, existing polishing wheels are fixed to the drive motor via a connecting shaft, requiring the entire polishing wheel to be replaced during installation and replacement. The drive motor's connecting shaft is in a free-rotating state, and the overall weight of the polishing wheel is excessive, making disassembly of the old polishing wheel or installation of the new one inconvenient. Utility Model Content
[0004] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a polishing device for drainage pipe production, solving the problem of the inconvenience of replacing the entire polishing wheel in traditional methods.
[0005] Technical solution To achieve the above objectives, this utility model provides the following technical solution: a polishing device for producing drainage pipes, comprising an installation roller, on which several polishing parts are detachably installed. Several installation grooves are formed on the outer wall of the installation roller. Each polishing part includes a slider that matches the installation groove, a mounting seat disposed on the slider, and a polishing disc mounted on the mounting seat. The polishing parts have various models, and the mounting seat heights of different models of polishing parts are different. Different models of polishing parts are installed in the installation grooves to adapt to drainage pipes with different inner diameters.
[0006] Furthermore, the polished part is connected to the mounting roller via a fixing assembly.
[0007] Furthermore, the fixing component includes a connecting block fixed on the slider and a bolt mounted on the connecting block, and the mounting roller has a screw hole that matches the bolt.
[0008] Furthermore, the slider slides along the length of the mounting groove, and the slider is adapted to the mounting groove.
[0009] Furthermore, one end of the mounting roller is coaxially connected to a connecting shaft.
[0010] Furthermore, the end of the connecting shaft is connected to the rotating end of the drive motor.
[0011] Beneficial effects Compared with the prior art, this utility model provides a polishing device for the production of drainage pipes, which has the following beneficial effects: This polishing device for drainage pipe production features a mounting groove and slider structure that breaks down the traditional integral polishing wheel into easily replaceable independent polishing parts. This allows operators to simply replace the polishing part with the one corresponding to the inner diameter of the drainage pipe, eliminating the need to disassemble the bulky polishing wheel itself and significantly reducing the difficulty and physical exertion during replacement. Furthermore, the differentiated mounting height design for different models of polishing parts precisely adapts to the polishing needs of various pipe diameters, avoiding repeated disassembly and reassembly due to size differences and significantly shortening equipment setup time. In addition, the lightweight polishing part design effectively reduces the handling burden during replacement compared to traditional integral polishing wheels, and the high-precision slider and mounting groove positioning structure ensures the stability of the polishing parts after installation.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-7 This utility model discloses a polishing device for producing drainage pipes, comprising an installation roller 1, one end of which is coaxially connected to a connecting shaft 9, and the end of the connecting shaft 9 is connected to the rotating end of a drive motor 10. Several polishing parts are detachably installed on the installation roller 1. Several installation grooves 2 are formed on the outer wall of the installation roller 1. The polishing parts include a slider 3 that matches the installation groove 2, a mounting seat 4 set on the slider 3, and a polishing plate 5 installed on the mounting seat 4. The polishing plate 5 and the mounting seat 4 can be detachably connected by Velcro. The polishing parts have various models, and the mounting seat 4 of different models of polishing parts has different heights. Different models of polishing parts are installed in the installation grooves 2 to adapt to drainage pipes with different inner diameters.
[0016] The polishing part is connected to the mounting roller 1 via a fixing assembly, which includes a connecting block 6 fixedly mounted on the slider 3 and a bolt 7 mounted on the connecting block 6. The mounting roller 1 has a threaded hole 8 that matches the bolt 7. The slider 3 slides along the length of the mounting groove 2, and the slider 3 is adapted to the mounting groove 2. The slider 3 of the polishing part is slid into the mounting groove 2, and then the bolt 7 is screwed into the threaded hole 8 to fix the polishing part on the mounting roller 1.
[0017] In summary, this polishing device for drain pipe production, when in use, selects a polishing part model that matches the height of the mounting base 4 according to the inner diameter of the drain pipe to be polished, ensuring that the polishing disc 5 can effectively fit the inner wall of the drain pipe. Unscrew the bolts 7 that previously fixed the polishing part, and smoothly slide it out from the mounting groove 2 on the outer wall of the mounting roller 1 along the sliding direction to complete the disassembly. Align the selected polishing part with the mounting groove 2 and slowly slide it in along the groove direction, so that the slider 3 on the polishing part fits tightly with the mounting groove 2. Then screw the bolts 7 into the screw holes 8 corresponding to the mounting base 4 and the mounting groove 2, and firmly fix the polishing part in the mounting groove 2 by tightening the bolts 7 to complete the installation. Insert the mounting roller 1 with the matching polishing part into the drain pipe as a whole, ensuring that the mounting roller 1 is coaxial with the drain pipe. Start the drive motor 10 to drive the mounting roller 1 and the polishing part to rotate at high speed. Through the contact friction between the polishing disc 5 and the inner wall of the drain pipe, the inner wall of the drain pipe is polished efficiently.
[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
