Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning, specifically a device for descaling and dewaxing the inner wall of a pipeline. Background Technology

[0002] In fields such as petrochemicals, heating and water supply, scale and wax residue on the inner wall of pipelines can lead to reduced transport efficiency, increased energy consumption, and even serious problems such as pipeline blockage. With the expansion of industrial production scale and the diversification of pipeline application scenarios, traditional descaling and dewaxing equipment is gradually becoming unable to meet actual needs.

[0003] Most existing equipment is designed for specific pipe diameters and cannot flexibly adapt to pipes of different sizes. When faced with changes in pipe diameter, either the device is too large to enter the pipe, or it is too small to clean thoroughly, making it difficult to achieve full-scene coverage. Manual operation or simple mechanical structures cannot automatically scrape the inner wall of the pipe completely. In complex working conditions such as long-distance pipelines, it is even more difficult to reach the depths of the pipe, resulting in low cleaning efficiency. Therefore, it is necessary to design a pipe inner wall descaling and dewaxing device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a device for descaling and dewaxing the inner wall of a pipe, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe inner wall descaling and dewaxing device, comprising a mounting column, a plurality of rotating frames rotatably mounted on the outer side of the mounting column, a first motor mounted on one side of the rotating frame, a wheel fixedly mounted on the output end of the first motor to abut against the inner wall of the pipe, and an adjustment component for driving the rotating frames to rotate mounted on the outer side of the mounting column.

[0006] A fixing sleeve is fixedly installed on the outside of the mounting column, a rotating plate is rotatably installed on the outside of the fixing sleeve, an adjustable scraping component is installed on the outside of the rotating plate, and a driving component for driving the rotating plate to rotate is installed on one side of the mounting column.

[0007] Preferably, the adjustment assembly includes a movable sleeve and a mounting plate. The movable sleeve is slidably mounted on the outside of the mounting column. A plurality of connecting plates are hinged to one side of the movable sleeve. The end of the connecting plate away from the movable sleeve is hinged to one side of the rotating frame. The mounting plate is fixedly mounted on the outside of the mounting column. An electric push rod is fixedly mounted on one side of the mounting plate. One end of the inner rod of the electric push rod is fixed to one side of the movable sleeve.

[0008] Preferably, the scraping assembly includes a guide rod, a sliding plate slidably mounted on the outer side of the guide rod, a support rod mounted on one side of the sliding plate, a scraper fixedly mounted on one end of the support rod, and a threaded component for driving the sliding plate to move mounted on the outer side of the rotating plate.

[0009] Preferably, the threaded component is a threaded rod, which is rotatably mounted on the outside of the rotating plate, and the threaded rod threaded through the sliding plate.

[0010] Preferably, the drive assembly includes a fixed plate and an annular plate. The annular plate is fixedly installed on one side of the rotating plate, and a plurality of teeth are fixedly installed on the inner side of the annular plate. The fixed plate is fixedly installed on one side of the mounting column, and a second motor is installed on one side of the fixed plate. A gear is fixedly installed at the output end of the second motor, and the gear meshes with the teeth.

[0011] Preferably, the teeth are distributed in a ring at equal intervals on the inner side of the annular plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This pipe inner wall descaling and dewaxing device, by turning on the switch of the electric push rod, changes the position of the movable sleeve, thereby driving the connecting plate to rotate, and causing the rotating frame and wheels to swing, so that the six wheels can contact the inner wall of the pipe. Turning on the switch of the first motor drives the wheels to rotate, so that the whole device can move on the inner wall of the pipe. It can adapt to different pipe inner diameters and can go deep into the pipe for cleaning.

[0014] 2. This pipe inner wall descaling and dewaxing device uses a rotating threaded rod to drive a sliding plate to slide outside the guide rod, changing the position of the sliding plate, support rod, and scraper so that the scraper can contact the inner wall of the pipe, facilitating subsequent descaling and dewaxing. Turning on the second motor drives the gear to rotate, and the gear drives the annular plate to rotate through its teeth, thus causing the rotating plate to rotate. The rotating plate, through the guide rod, sliding plate, and support rod, drives the scraper to rotate, performing descaling and dewaxing work on the inner wall of the pipe. As the entire device moves, it can clean different positions on the inner wall of the pipe. After scraping, the scraped scale and wax can be washed away with water, thus completing the cleaning work.

[0023] A fixing sleeve 9 is fixedly installed on the outside of the mounting column 1. A rotating plate 10 is rotatably installed on the outside of the fixing sleeve 9. An adjustable scraping component is installed on the outside of the rotating plate 10. A drive component for driving the rotating plate 10 to rotate is installed on one side of the mounting column 1.

[0024] Specifically, by adjusting the component, the rotating frame 2 and the wheel 4 are driven to swing, so that the wheel 4 can contact the inner wall of the pipe, making it easier for the device to move inside the pipe. The drive component drives the rotating plate 10 and the scraping component to rotate to perform descaling and dewaxing work.

[0025] The adjustment assembly includes a movable sleeve 5 and a mounting plate 7. The movable sleeve 5 is slidably installed on the outside of the mounting column 1. Multiple connecting plates 6 are hinged to one side of the movable sleeve 5. The end of the connecting plate 6 away from the movable sleeve 5 is hinged to one side of the rotating frame 2. The mounting plate 7 is fixedly installed on the outside of the mounting column 1. An electric push rod 8 is fixedly installed on one side of the mounting plate 7. One end of the inner rod of the electric push rod 8 is fixed to one side of the movable sleeve 5. By turning on the switch of the electric push rod 8, the position of the movable sleeve 5 is changed, thereby driving the connecting plate 6 to rotate and driving the rotating frame 2 and the wheels 4 to swing, so that the six wheels 4 can contact the inner wall of the pipe.

[0026] The scraping assembly includes a guide rod 16, a sliding plate 17 slidably mounted on the outside of the guide rod 16, a support rod 18 mounted on one side of the sliding plate 17, and a scraper 19 fixedly mounted on one end of the support rod 18. A threaded component for moving the sliding plate 17 is mounted on the outside of the rotating plate 10. The threaded component is a threaded rod 20, which is rotatably mounted on the outside of the rotating plate 10. The threaded rod 20 passes through the sliding plate 17. By rotating the threaded rod 20, the sliding plate 17 is moved to slide on the outside of the guide rod 16, changing the position of the sliding plate 17, the support rod 18, and the scraper 19, so that the scraper 19 can contact the inner wall of the pipe, facilitating subsequent descaling and dewaxing work.

The teeth 12 are distributed in an annular pattern with equal spacing on the inner side of the annular plate 11. When the switch of the second motor 14 is turned on, the gear 15 is driven to rotate. The gear 15 drives the annular plate 11 to rotate through the teeth 12, thereby causing the rotating plate 10 to rotate.

[0028] Working principle: This utility model is a pipe inner wall descaling and dewaxing device. When in use, by turning on the switch of the electric push rod 8, the position of the movable sleeve 5 is changed, thereby driving the connecting plate 6 to rotate, and driving the rotating frame 2 and the wheels 4 to swing, so that the six wheels 4 can contact the inner wall of the pipe. Turning on the switch of the first motor 3 drives the wheels 4 to rotate, so that the whole device can move on the inner wall of the pipe. It can adapt to different pipe inner diameters.

[0029] By rotating the threaded rod 20, the sliding plate 17 is driven to slide outside the guide rod 16, changing the position of the sliding plate 17, the support rod 18, and the scraper 19, so that the scraper 19 can contact the inner wall of the pipe, which facilitates the subsequent descaling and dewaxing work. The switch of the second motor 14 is turned on, which drives the gear 15 to rotate. The gear 15 drives the annular plate 11 to rotate through the teeth 12, thereby causing the rotating plate 10 to rotate. The rotating plate 10 drives the scraper 19 to rotate through the guide rod 16, the sliding plate 17, and the support rod 18, so as to perform descaling and dewaxing work on the inner wall of the pipe. As the whole device moves, it can clean different positions on the inner wall of the pipe. After scraping, the scraped scale and wax can be washed away with water, thus completing the cleaning work.

[0030] It is worth noting that the first motor 3, electric push rod 8, and second motor 14 used in the device are all controlled by a microcontroller and remote wireless control is achieved through a wireless transmission module.
