Description

Technical Field

[0001] This utility model relates to the technical field of building gas pipeline construction, and in particular to a pipeline inner wall cleaning device. Background Technology

[0002] Building gas pipelines refer to dedicated piping systems used to safely and stably transport gas into buildings and distribute it to users' indoor gas appliances, such as gas stoves and water heaters. Building gas pipelines are the intermediate link connecting the municipal gas system and user terminals, primarily responsible for the transmission and distribution of gas within buildings. Building gas pipelines typically include inlet pipes, risers, branch pipes, and indoor pipes. Inlet pipes connect the municipal gas system to the building and can be equipped with a main valve to control the gas inlet. Riser pipes are the vertical main pipelines running from the ground floor to the top floor, responsible for the vertical distribution of gas. Branch pipes branch off from the risers to the horizontal or vertical pipelines of each household, ultimately connecting to the indoor gas appliances. Indoor pipes are the final pipes connecting the user's indoor gas appliances.

[0003] In the field of building gas pipeline construction, long-distance gas pipelines are generally constructed by welding multiple pipe sections. For example, the connection between the inlet pipe and the riser, the laying of the riser, and the distribution and connection of branch pipes all require welding multiple pipes together. Welds are formed between these pipe sections; these welds need to be ground and painted. Otherwise, the welds are prone to corrosion, leading to leaks or even breakage. Debris is generated during the weld grinding process. Furthermore, during gas pipeline laying, dust, foreign objects, and impurities can easily accumulate inside the pipeline. If these are not cleaned and collected in a timely manner, they will affect the normal operation of the pipeline.

[0004] Based on this, Chinese patent document CN113522898B discloses a pipe inner wall dirt cleaning device, which includes a control box and a drive motor. The control box and the drive motor are connected by a support frame. One end of a rotating adjustment shaft is connected to the support frame through a first bearing, and the other end of the rotating adjustment shaft is threaded with a first threaded post. One end of the first threaded post is fixedly connected to a mounting block located inside the control box. Support slide plates are fixedly connected to the top and bottom of the mounting block. A movable slide plate is provided on one side of the support slide plate. Two support plates are fixedly connected to the control box. One end of the movable slide plate is fixedly connected to a mounting seat located outside the control box. The mounting seat and the support plates are connected by several tension springs. A scraper is provided on the mounting seat. The pipe inner wall dirt cleaning device disclosed in this patent document can adjust the distance between the scraper and the control box according to the size of the pipe inner diameter, eliminating the need for manual scraping of dirt, saving time and effort.

[0005] However, the aforementioned pipe inner wall cleaning device still suffers from technical problems related to poor cleaning efficiency. Specifically, although the aforementioned pipe inner wall cleaning device can adjust the distance between the scraper and the control box according to the pipe's inner diameter to make it applicable to cleaning dust, foreign objects, and impurities in pipes of different diameters, during the construction of gas pipelines, it is still necessary for the cleaning structure to extend and feed along the axial direction of the gas pipeline when cleaning the inside of the pipe. However, existing technologies cannot achieve automatic feeding and cleaning operations, often requiring manual feeding operations by operators, which is time-consuming and labor-intensive, affecting the cleaning efficiency of the gas pipeline inner wall.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0028] Please refer to the following: Figures 1 to 4 This utility model discloses a pipe inner wall cleaning device, comprising: a base 1, a feed drive mechanism 2, a rotary drive mechanism 3, a cleaning fixture 4, a supporting fixture 5, and a clamping mechanism 6; the feed drive mechanism 2 is disposed on one side of the base 1, the rotary drive mechanism 3 is movably disposed on the base 1, and the feed drive mechanism 2 and the rotary drive mechanism 3 are drivenly connected; the cleaning fixture 4 is disposed above the base 1 adjacent to the rotary drive mechanism 3, and the rotary drive mechanism 3 is drivenly connected to the cleaning fixture 4; the supporting fixture 5 is connected to the base 1 adjacent to the cleaning fixture 4, and the clamping mechanism 6 is disposed opposite to the supporting fixture 5.

[0029] Specifically, when the pipe inner wall cleaning device of this utility model is in operation, the pipe whose inner wall needs to be cleaned can be placed on the supporting fixture 5, and the cleaning fixture 4 is located at one end of the pipe or inside the pipe; then, the clamping mechanism 6 is activated and clamps the pipe onto the supporting fixture 5; next, the rotary drive mechanism 3 is activated and drives the cleaning fixture 4 to start rotating, and at the same time, the feed drive mechanism 2 is activated and drives the rotary drive mechanism 3 to move the cleaning fixture 4 forward; thus, when the cleaning fixture 4 is driven to rotate, the pipe whose inner wall needs to be cleaned can be cleaned step by step, and it can automatically move forward along the axial direction inside the pipe until the inner wall of the pipe section is completely cleaned; finally, the feed drive mechanism 2 drives the rotary drive mechanism 3 to move the cleaning fixture 4 back to its original position. After the cleaning fixture 4 is reset, the supporting fixture 5 releases its clamping constraint on the pipe. Therefore, the pipe inner wall cleaning device of this utility model can automatically clean the inner wall of the pipe and can automatically feed forward along the axial direction of the inner wall of the pipe to facilitate the automatic cleaning of the entire pipe inner wall; thus, the pipe inner wall cleaning device of this utility model solves the technical problem of how to improve the feeding and cleaning efficiency of the inner wall of gas pipeline.

[0030] Furthermore, the feed drive mechanism 2 includes a feed frame 201, a feed cylinder 202, a feed telescopic piston rod 203, a feed rail 204, a plurality of feed sliding blocks 205, and a feed moving platform 206; the feed frame 201 is connected to the base 1, and the feed cylinder 202 is disposed on one side of the feed frame 201; the feed telescopic piston rod 203 is movably disposed within the feed cylinder 202, and the feed cylinder 202 is drivenly connected to the feed telescopic piston rod 203; two feed rails 204 are arranged parallel to each other on the base 1, and a plurality of feed sliding blocks 205 are movably connected to each feed rail 204; each feed sliding block 205 is connected to the bottom of the feed moving platform 206, and the feed telescopic piston rod 203 is connected to the feed moving platform 206.

[0031] Furthermore, the rotary drive mechanism 3 includes a motor base 301, a rotary motor 302, an output wheel 303, a transmission belt 304, a transmission wheel 305, a transmission shaft 306, bearings 307, and a coupling 308. The motor base 301 is connected to the feed moving platform 206, the rotary motor 302 is connected to the motor base 301, the rotary motor 302 is drivenly connected to the output wheel 303, and the transmission belt 304 connects the output wheel 303 and the transmission wheel 305 respectively. The transmission wheel 305 is connected to the transmission shaft 306, and the two bearings 307 are arranged relatively spaced on the feed moving platform 206, with the transmission shaft 306 passing through the two bearings 307. The transmission shaft 306 is drively connected to the coupling 308.

[0032] Furthermore, the cleaning fixture 4 has a transmission link 401, a first cleaning part 402, and a second cleaning part 403; the transmission link 401 is connected to the coupling 308, the first cleaning part 402 is connected to the transmission link 401, and the second cleaning part 403 is movably connected to the first cleaning part 402.

[0033] Furthermore, the supporting fixture 5 has a supporting base 501, a receiving cavity 502, and a limiting bracket 503; the supporting base 501 is connected to the machine base 1, the receiving cavity 502 is disposed on the supporting base 501, and the limiting bracket 503 is disposed on the adjacent side of the receiving cavity 502.

[0034] Furthermore, the clamping mechanism 6 includes a hanger 601, a clamping cylinder 602, a clamping telescopic piston rod 603, and a contour clamping part 604; the hanger 601 is disposed on the support seat 501, the clamping cylinder 602 is drivenly connected to the clamping telescopic piston rod 603, the contour clamping part 604 is disposed below the clamping cylinder 602 relative to the accommodating cavity 502, and the clamping telescopic piston rod 603 is connected to the contour clamping part 604.

[0035] Specifically, when the feed cylinder 202 is activated, it drives the feed telescopic piston rod 203 to reciprocate in lengthening or shortening. This, in turn, drives the feed moving platform 206 to reciprocate forward or backward along the feed rail 204. As the feed moving platform 206 moves, several feed sliding blocks 205 at its bottom can move along the limits of the feed rail 204, making the reciprocating motion of the feed moving platform 206 smoother and more stable. When the feed moving platform 206 reciprocates forward or backward, the rotary drive mechanism 3 connected to it can follow its reciprocating motion, thereby driving the cleaning fixture 4 to reciprocate forward or backward, thus fulfilling the requirements for automatic feeding and resetting.

[0036] Specifically, after the rotary motor 302 starts, it drives the output wheel 303 to rotate, thereby transmitting power to the transmission wheel 305 via the transmission belt 304, which in turn drives the transmission shaft 306 to rotate. When the transmission shaft 306 rotates, it drives the coupling 308, causing the cleaning fixture 4 to rotate accordingly. Because the transmission wheel 305 is positioned between the two bearings 307, the transmission wheel 305 can drive the transmission shaft 306 to rotate with greater stability.

[0037] Specifically, the transmission link 401 transmits the power of the transmission shaft 306 to the first cleaning part 402 and the second cleaning part 403 via the coupling 308. Both the first cleaning part 402 and the second cleaning part 403 can clean the inner wall of the pipe; for example, their outer contours can be used as brushes, grinding wheels, or similar cleaning structures. More specifically, the second cleaning part 403 can be detached from the end of the first cleaning part 402 because it can be configured as a flexible structure, thereby enabling the cleaning of the inner wall of curved pipes, such as corner pipes.

[0038] Specifically, the pipe to be cleaned can be placed on the receiving cavity 502. Then, the clamping cylinder 602 is activated, driving the clamping telescopic piston rod 603 to extend or retract. This causes the contour clamping part 604 to move closer to or away from the receiving cavity 502 and the limiting bracket 503. The limiting bracket 503 is used to assist in limiting the outer wall of the pipe, making the pipe clamped more securely. When the contour clamping part 604 moves downwards towards the receiving cavity and the limiting bracket 503, it can clamp the pipe onto the receiving cavity 502 and the limiting bracket 503. When the contour clamping part 604 moves upwards away from them, it can release the clamping of the pipe.

[0039] In summary, this utility model provides a pipe inner wall cleaning device comprising a base 1, a feed drive mechanism 2, a rotary drive mechanism 3, a cleaning fixture 4, a supporting fixture 5, and a clamping mechanism 6. The feed drive mechanism 2 is mounted on one side of the base 1, and the rotary drive mechanism 3 is movably mounted on the base 1, with the feed drive mechanism 2 and the rotary drive mechanism 3 being drivenly connected.

Therefore, this utility model provides a pipe inner wall cleaning device that solves the technical problem of how to improve the feeding and cleaning efficiency of the inner wall of a gas pipeline.
