Description

Technical Field

[0001] This utility model relates to the field of rust removal equipment technology, and in particular to a rust removal equipment for building pipelines. Background Technology

[0002] In the field of building engineering, pipelines, as critical infrastructure, are widely used in many systems such as water supply and drainage, heating, and ventilation. They undertake important functions such as media transportation and environmental control. Their stable operation is directly related to the overall performance of the building. Due to the combined effects of media erosion, changes in environmental humidity, oxidation reactions, and corrosion by external corrosive substances during long-term use, the inner and outer walls of pipelines are prone to rust. The continuous accumulation of rust not only leads to a reduction in the inner diameter of the pipeline, seriously affecting its transportation efficiency and flow performance, but also gradually erodes the pipeline body over time, causing the pipeline wall thickness to decrease and even corrosion perforation. This not only causes safety problems such as media leakage, but also significantly shortens the service life of the pipeline, posing a great hidden danger to the normal operation of the building system. Existing methods for rust removal from building pipelines typically involve manual grinding, which is not only inefficient and time-consuming but also extremely labor-intensive. Workers often operate in confined and complex spaces in harsh environments. Furthermore, for long pipelines, especially buried ones or those in unusual locations, rust removal equipment struggles to penetrate deeply enough for thorough and effective grinding, creating blind spots and compromising rust removal results. These methods often focus solely on removing the rust layer, lacking a mechanism for timely cleaning of rust generated during the grinding process. This results in rust residue remaining inside or on the surface of the pipeline, affecting its future use. Moreover, the lack of effective maintenance measures for the pipeline's inner walls after rust removal leaves the pipeline vulnerable to re-corrosion and rusting within a short period. This not only diminishes the practical value of rust removal but also repeatedly increases maintenance costs and workload, placing a heavy burden on the long-term maintenance of building pipelines. Therefore, this invention proposes a rust removal device for building pipelines. Utility Model Content

[0003] The purpose of this invention is to address the problems in the background technology where manual grinding is not only inefficient and requires a lot of manpower and time, but also difficult for long pipelines, especially buried pipelines or long pipelines in special installation locations, as the rust removal equipment cannot penetrate deep into the interior for comprehensive and effective grinding, easily creating blind spots in rust removal and failing to guarantee the rust removal effect. After rust removal, there are also no effective maintenance measures for the inner wall of the pipeline, leaving the pipeline without necessary protection and making it very easy for it to corrode and rust again in a short period of time. This not only reduces the practical significance of rust removal work, but also repeatedly increases maintenance costs and workload, placing a heavy burden on the long-term maintenance of building pipelines. Therefore, this invention proposes a rust removal device for building pipelines.

[0037] Example

[0038] like Figures 1 to 4 As shown, this utility model proposes a rust removal device for building pipelines, including a walking assembly 1, a rust removal assembly 2, a maintenance assembly 3, a camera, and a controller. The walking assembly 1 can mount the various components of the rust removal device and provide a stable foundation for the device's movement within the pipeline. The main structure of the walking assembly 1 includes a mounting base 11, providing support for the other components. A columnar movable column 12 is fixedly connected to the mounting base 11, and a movable block 13, which can move freely along its axial direction, is fitted onto the movable column 12. The movable block 13 can adjust the position of the track wheels 14.

[0039] The movable block 13 is hinged to three sets of evenly distributed 120-degree abutment arms 15 on its outer side. The other end of each abutment arm 15 is fixed with a track wheel 14 via a rotating shaft. The track wheel 14 is the actuator for the equipment's movement, and a pressure sensor 18 is embedded in its surface. The pressure sensor 18 is electrically connected to the controller and can sense the pressure between the track wheel 14 and the inner wall of the pipe in real time. The abutment arms 15 and the track wheels 14 are rotatably connected, allowing them to adapt to changes in the curvature of the inner wall of the pipe.

[0040] Furthermore, a fixed block 16 is fixedly installed on the side of the movable block 13 away from the mounting base 11. Three sets of follower arms 17 are also hinged on the fixed block 16. The other end of the follower arm 17 is also rotatably connected to the track wheel 14 through a rotating shaft. The abutment arm 15 and the follower arm 17 have a scissor-like cross structure. This structure can ensure that the track wheel 14 always maintains a stable posture during the adjustment process.

[0041] In addition, the mounting base 11 is equipped with a drive assembly that is fixedly connected to the movable block 13. The drive assembly can adopt a hydraulic push rod or a lead screw 242 slider structure. Under the push and pull action of the drive assembly, the movable block 13 moves up and down along the movable column 12. Then, under the coordinated action of the push arm 15 and the follower arm 17, it drives the three sets of track wheels 14 to converge towards the center or spread outward in sync to adapt to pipes of different diameters.

[0042] Furthermore, camera 4 is fixedly installed at one end of the traveling component 1 in the direction of travel, and can capture real-time images of the inside of the pipe and transmit them to an external terminal. The controller, specifically model XD3-32MT / 32MR transistor or relay output type (existing technology, not described in detail here), is fixedly installed inside the cavity of the traveling component 1. It is electrically connected to the drive component of the traveling component 1, the pressure sensor 18, the motors of the rust removal component 2, the nozzle 33 and resistance wire of the maintenance component 3, and the camera 4, achieving unified control of the entire equipment.

[0043] As one implementation method, such as Figure 1 , Figure 5 and Figure 6 As shown, the rust removal component 2 is fixedly installed on the side opposite to the travel direction of the traveling component 1, and is specifically used for cleaning rust from the inner wall of the pipe. Its structure includes a connecting seat 21 fixedly installed at one end of the traveling component 1, which connects the traveling component 1 to other components of the rust removal component 2. A hollow mounting cavity 22 is fixedly connected to the side of the connecting seat 21 away from the traveling component 1; the mounting cavity 22 serves as the mounting carrier for the telescopic component 24.

[0044] The mounting cavity 22 is externally connected to four sets of evenly distributed limiting cylinders 23 along the circumferential direction. The limiting cylinders 23 are tubular and serve to guide and limit the internal components. An expansion joint 24 is installed inside the mounting cavity 22, one end of which passes through the limiting cylinder 23 and is fixedly connected to a wire brush 25. The distance between the wire brush 25 and the inner wall of the pipe can be adjusted by the expansion and contraction of the expansion joint 24.

[0045] In addition, the four sets of wire brushes 25 on the rust removal component 2 have different specifications and are all made of high-strength stainless steel wire, which can adapt to the cleaning needs of different rust layer thicknesses. An ultrasonic vibrator 26 is fixedly connected to the upper end of the connecting seat 21, which accelerates the removal of rust from the inner wall of the pipe; a power component 27 is fixedly connected to the bottom of the connecting seat 21, which is used to make the connecting seat 21 and the components connected thereto rotate around the central axis of the connecting seat 21, thereby achieving all-round rust removal.

[0046] As one implementation method, such as Figure 1 , Figure 8 and Figure 9 As shown, the maintenance component 3 is fixedly installed at the end of the rust removal component 2 away from the travel component 1, and is used to maintain the inner wall of the pipe after rust removal. Its structure includes a shock-absorbing base 31 movably disposed on the side of the rust removal component 2 away from the travel component 1. The shock-absorbing base 31 has internal threads, which are connected to the ultrasonic vibrator 26 by engaging with the external threads on the outside, thereby reducing the vibration impact of the rust removal component 2 on the maintenance component during operation.

[0047] The upper end of the shock-absorbing base 31 is equipped with a sealed oil reservoir 32 for storing maintenance grease. Multiple sets of nozzles 33 arranged in a ring array are installed on the outside of the oil reservoir 32 to evenly spray the grease onto the inner wall of the pipe. A connecting frame 34 is fixedly installed on the side of the oil reservoir 32 away from the shock-absorbing base 31. A sponge 35 is fitted over the connecting frame 34 to evenly spread the sprayed grease onto the inner wall of the pipe. A thin resistance wire is embedded inside the connecting frame 34. The thin resistance wire is electrically connected to a controller. Current flowing through the resistance wire generates heat, which is transferred to the sponge 35, thereby drying the inner wall of the pipe.

[0048] Furthermore, such as Figure 1 , Figure 5 and Figure 6 As shown, the ultrasonic vibrating component 26 includes a vibration support 266 fixedly installed on the side of the mounting cavity 22 away from the walking assembly 1. An ultrasonic transducer 261, the core component for converting electrical energy into mechanical energy, is disposed inside the vibration support 266. A vibration arm 262 is connected to the ultrasonic transducer 261, and a vibration bracket 263 is fixedly connected to the other end of the vibration arm 262. Four sets of evenly arranged limiting posts 264 are fixedly installed around the vibration bracket 263. The end of each limiting post 264 away from the vibration bracket 263 is movably inserted through the upper end of the wire brush 25.

[0049] Additionally, an installation bracket 265 is movably sleeved on the limiting post 264. The lower end of the installation bracket 265 is fixedly installed on the wire brush 25, and the upper end can slide along the limiting post 264, so that the rubber hammer 267 set on the side of the installation bracket 265 near the inner wall of the pipe will move with the extension and retraction of the wire brush 25, ensuring that the rubber hammer 267 can always contact and strike the inner wall of the pipe.

[0050] like Figure 5 and Figure 7 As shown, the telescopic component 24 includes a transmission bevel gear 241 movably disposed inside the mounting cavity 22. A first motor 245 is disposed at the bottom of the transmission bevel gear 241, and the output end of the first motor 245 is fixedly connected to the transmission bevel gear 241 to provide power for transmission. Four sets of evenly arranged driven bevel gears 243 are disposed at the upper end of the transmission bevel gear 241. The transmission bevel gear 241 and the driven bevel gears 243 mesh with each other to transmit power to the driven bevel gears 243. A lead screw 242 is fixedly connected to the other end of the driven bevel gear 243. A movable cylinder 244 is threadedly engaged with the outside of the lead screw 242. The movable cylinder 244 is movably disposed inside the limiting cylinder 23. When the lead screw 242 rotates, the movable cylinder 244 can move axially along the limiting cylinder 23, thereby driving the wire brush 25 to extend and retract.

[0051] like Figure 6 and Figure 7As shown, the power component 27 includes a driven gear 271 fixedly connected to the bottom of the mounting cavity 22. A transmission gear 272 meshing with the driven gear 271 is provided on one side. A second motor 273 is provided on one side of the transmission gear 272. The output end of the second motor 273 is fixedly connected to the transmission gear 272. The rotation of the motor drives the gear transmission, ultimately realizing the rotation of the connecting seat 21 and the rust removal component 2.

[0052] In this embodiment, the equipment is placed stably at the inlet of the inclined pipe. This placement utilizes the pipe's inclination angle, allowing the rust removed during grinding to slide out of the pipe under gravity, reducing rust residue inside. Next, the operator inputs relevant pipe parameters, including pipe diameter, pipe material, and an estimated rust layer, through an operating terminal connected to the controller. These parameters are fundamental to the equipment's normal operation and directly affect the working status of each component.

[0053] After the parameters are set, the equipment enters the walking preparation stage. The controller sends a command to the drive component of the walking assembly 1 according to the preset pipe diameter parameters. The drive component then starts, driving the movable block 13 to move on the movable column 12. Under the coordinated action of the supporting arm 15 and the following arm 17, the three sets of track wheels 14 gradually adjust to the appropriate opening degree until they are in close contact with the inner wall of the pipe, thus providing a stable foundation for the equipment to walk in the pipe.

[0054] The equipment then begins to move inside the pipe. The track wheels 14 generate friction with the inner wall of the pipe, propelling the equipment slowly along its path. During this movement, pressure sensors 18 on the track wheels 14 monitor the pressure data between the track wheels 14 and the inner wall of the pipe in real time, continuously feeding this data back to the controller. Based on pressure changes, the controller adjusts the travel speed and pressure distribution on the track wheels 14 in a timely manner, ensuring the equipment maintains a stable movement and preventing shaking or stalling due to uneven pressure or improper speed.

[0055] Once the equipment reaches the designated rust removal position, the rust removal assembly 2 is activated. The second motor 273 starts working first, driving the transmission gear 272 to rotate. Through meshing with the driven gear 271, the connecting seat 21 and the entire rust removal assembly 2 rotate around its central axis, preparing for all-around rust removal. At the same time, the first motor 245 drives the transmission bevel gear 241 to rotate. The transmission bevel gear 241 meshes with four sets of driven bevel gears 243, driving the lead screw 242 to rotate, causing the movable cylinder 244 to extend from the limiting cylinder 23, thereby bringing the wire brush 25 closer to the inner wall of the pipe.

[0056] During the rust removal operation, the ultrasonic transducer 261 converts electrical energy into mechanical energy, generating high-frequency vibrations. These vibrations are transmitted to the wire brush 25 and rubber hammer 267 via the vibrating arm 262, vibrating support 263, and limiting post 264. The rubber hammer 267 continuously strikes the inner wall of the pipe under the action of ultrasonic vibrations, loosening the rust and facilitating subsequent cleaning. Meanwhile, the wire brushes 25 of different specifications target and scrape the inner wall of the pipe according to the preset rust layer condition, utilizing the properties of their high-strength stainless steel wire to efficiently remove rust and achieve thorough rust removal.

[0057] While the rust removal operation is underway, the maintenance component 3 is activated simultaneously, enabling seamless rust removal and maintenance. The controller activates the nozzle 33 outside the oil reservoir 32, spraying grease evenly onto the rust-treated inner wall of the pipe. Simultaneously, the fine resistance wire inside the connecting frame 34 is energized, and the controller adjusts the current according to a preset program, generating appropriate heat that is transferred to the sponge 35. As the equipment moves forward, the sponge 35, carrying grease and heat, evenly spreads the sprayed grease onto the inner wall of the pipe, simultaneously drying the pipe and forming a dense protective film on the inner wall, effectively completing the pipe maintenance.

[0058] After the equipment completes the rust removal and maintenance work on the entire pipeline, it begins its return journey. The equipment returns along the original pipeline route to the pipeline inlet. Upon reaching the inlet, the controller controls the drive component of the walking assembly 1 to operate, causing the track wheels 14 to retract, reducing the overall size of the equipment and making it easier for operators to remove the equipment from the pipeline.

[0059] After the equipment is removed, further processing is required. Operators will thoroughly clean the equipment, removing rust, grease, and other debris from all parts. They will then meticulously inspect each component for damage or wear, repairing or replacing any damaged parts as needed. This ensures the equipment is always in good working order and is fully prepared for the next operation.

[0060] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
