Description

Technical Field

[0001] This application relates to the technical field of pipeline rust removal, and in particular to a device for grinding and removing rust from the pipe walls of water supply pipelines in mountainous areas. Background Technology

[0002] In mountainous areas, steel pipes are commonly used as the main material for water supply pipelines, with adjacent pipes connected by welding. During daily use, the weld seams of these pipes are prone to corrosion. Prolonged corrosion can easily cause localized perforations in the pipes, leading to leaks and severely impacting the safety and stability of the water supply system. Therefore, regular rust removal and maintenance of the weld seams are necessary to ensure the normal operation of the water supply system in mountainous areas. Currently, rust removal work on water supply pipelines mainly relies on manual operation. Specifically, construction workers need to enter the water supply pipeline through the inspection port and then use rust removal tools such as wire brushes to grind and remove rust from the welds.

[0003] Regarding the aforementioned technologies, due to the limited internal space of water supply pipelines, on the one hand, manual operation is usually restricted, resulting in low overall operational efficiency; on the other hand, the relatively enclosed interior of water supply pipelines also poses certain risks to manual operation. Therefore, there is room for improvement. Utility Model Content

[0004] To facilitate rust removal at weld seams of water supply pipelines in mountainous areas, this application provides a device for grinding and removing rust from the pipe walls of water supply pipelines in mountainous areas.

[0005] This application provides a device for grinding and removing rust from the pipe walls of water supply pipelines in mountainous areas, which adopts the following technical solution: A device for grinding and removing rust from the pipe walls of water supply pipelines in mountainous areas, comprising an angle grinding mechanism and a traveling mechanism; The angle grinding mechanism includes a frame, and an angle grinder is arranged on the outside of the frame. The grinding head of the angle grinder is disposed away from the frame. The frame is provided with a drive assembly corresponding to the angle grinder. The drive assembly is used to drive the grinding head of the angle grinder to extend outward. The walking mechanism includes two end plates, the frame is located between the two end plates, and the two ends of the frame are rotatably connected to the two end plates respectively. At least three connecting rods are evenly distributed on the outer periphery of the end plates, and a roller is installed on the end of the connecting rod away from the end plate. The end plate located at the front end of the frame is provided with a rotary drive component, which is used to drive the frame to rotate; the end plate located at the front end of the frame is provided with a connector, which is used to connect the pipeline robot.

[0006] By adopting the above technical solution, after connecting the connector to the pipeline robot, the frame can move inside the water supply pipeline by its own walking mechanism in coordination with the pipeline robot. When the frame moves to the weld seam on the inner wall of the water supply pipeline, the angle grinder is started, and the drive component drives the wire brush of the angle grinder head to abut against the inner wall of the water supply pipeline. At the same time, the rotary drive component drives the frame to move the angle grinder around the circumference of the water supply pipeline, which can realize circumferential grinding and rust removal of the weld seam. Compared with the traditional manual operation method, the rust removal efficiency of the weld seam is effectively improved.

[0007] Preferably, both ends of the frame are rotatably connected to the two end plates via rotating shafts; the rotary drive includes a geared motor, the output end of which is connected to the rotating shaft at the end of the frame, for driving the rotating shaft to rotate the frame.

[0008] By adopting the above technical solution, the rotating shaft is driven by a geared motor, which in turn drives the frame to move the angle grinder around the water supply pipe, so as to more thoroughly grind the circumferential weld of the water supply pipe.

[0009] Preferably, the middle part of the angle grinder is hinged to the frame via a hinge bracket, and the hinge axis of the angle grinder is perpendicular to the rotation axis of the grinding head; the grinding head of the angle grinder is located near the front end of the frame. The drive assembly includes a connecting plate protruding from the outer side of the rear end of the frame. The connecting plate is connected to a tension spring. The end of the tension spring away from the connecting plate is connected to the end of the angle grinder near the grinding head. The tension spring is used to drive the end of the angle grinder near the grinding head to swing outward. The drive assembly also includes a traction electric cylinder, which is fixed to the frame. The traction electric cylinder and the tension spring are located on opposite sides of the angle grinder. The piston rod end of the traction electric cylinder is connected to the end of the angle grinder near the grinding head via a connecting rope.

[0010] By adopting the above technical solution, when the angle grinder travels inside the water supply pipeline, the piston rod is driven to retract by the traction electric cylinder. This retracts the end of the angle grinder near the grinding head and pulls it close to the frame via the connecting rope, restricting the grinding head from extending outward. This results in the grinding head interference device moving entirely inside the water supply pipeline. When performing grinding and rust removal operations, the piston rod is driven to extend by the traction electric cylinder, allowing the angle grinder head to extend outward under the action of the tension spring and abut against the inner wall of the water supply pipeline. This facilitates subsequent grinding and rust removal of the weld seam using the grinding head.

[0011] Preferably, each of the connecting rods has an elongated hole on its outer periphery, through which a plurality of connecting bolts are threaded and connected to the end plate.

[0012] By adopting the above technical solution, the distance between the roller and the end plate can be adjusted. When the inner diameter of the water supply pipe changes, the distance between the roller and the end plate can be adjusted so that the rollers at all points on the outer periphery of the end plate can abut against the inner wall of the water supply pipe, which helps to improve the overall applicability of the device.

[0013] Preferably, the connector includes a connecting pipe, both ends of which are connected to flanges, and one end of the connecting pipe is connected to the end plate by the flange.

[0014] By adopting the above technical solution, after connecting the flange at the end of the connecting pipe to the pipeline robot, a stable connection between the device and the pipeline robot can be achieved, which is conducive to the pipeline robot driving the device to move more stably in the water supply pipeline.

[0015] Preferably, a camera is installed on the end plate located at the rear end of the rack, the camera is positioned facing the front end of the rack, and the camera is connected to an external controller to acquire images of the inside of the water supply pipe and feed them back to the external controller.

[0016] By adopting the above technical solution, the camera can acquire real-time images of the inside of the water supply pipeline and promptly transmit them to the outside. This allows operators to understand the internal condition of the water supply pipeline in real time from the outside, and enables the pipe wall grinding and rust removal device to move more accurately to the weld seam of the water supply pipeline.

[0017] Preferably, a connecting flange pipe is also provided at the end plate located at the rear end of the frame, and the connecting flange pipe is used to connect external equipment.

[0018] By adopting the above technical solution, the pipe wall grinding and rust removal device can be connected to external equipment through connecting flange pipes according to actual operation needs, which is conducive to expanding the overall function of the pipe wall grinding and rust removal device.

[0019] Preferably, LED lights are installed on the side of the end plate away from the frame.

[0020] By adopting the above technical solution, installing LED lights on the side of the end plate away from the frame can enhance the light intensity inside the water supply pipe, improve lighting conditions, and make it easier for the camera to obtain clearer images of the inside of the water supply pipe.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. After connecting the connector to the pipeline robot, the pipe wall grinding and rust removal device can move inside the water supply pipeline through its own walking mechanism in conjunction with the traction of the pipeline robot. When the entire device moves to the weld of the water supply pipeline, the drive component drives the grinding head to abut against the weld on the inner wall of the water supply pipeline, and the rotary drive component drives the frame to rotate the wire brush at the grinding head of the angle grinder, thus realizing the grinding and rust removal of the weld and effectively improving the efficiency of weld grinding and rust removal.

[0022] 2. When traveling inside the water supply pipeline, the piston rod can be retracted by the traction cylinder of the drive assembly, so that the end of the angle grinder near the grinding head can be pulled close to the frame via the connecting rope, thus preventing the grinding head from extending outward and interfering with the overall movement of the device inside the water supply pipeline; during grinding operations, the piston rod is extended by the traction cylinder of the drive assembly, so that the end of the angle grinder near the grinding head extends outward under the action of the tension spring and abuts against the inner wall of the water supply pipeline, making it easier for the wire brush at the grinding head to grind and remove rust from the weld.

[0023] 3. By installing a camera on the end plate, the camera can acquire real-time images of the inside of the water supply pipeline and promptly transmit them to the outside. This allows operators to monitor the internal condition of the water supply pipeline from the outside, and enables the pipe wall grinding and rust removal device to move more accurately to the weld seam of the water supply pipeline.

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] This application discloses a device for grinding and removing rust from the pipe walls of water supply pipelines in mountainous areas, referring to... Figure 1 and Figure 2 The system includes an angle grinder 12 and a traveling mechanism 2. Specifically, the angle grinder 12 includes a frame 11, with angle grinders 12 mounted on opposite sides of the frame 11. The grinding head of the angle grinder 12 is positioned away from the frame 11, and a wire brush 121 is installed on the grinding head. A drive assembly 13 is provided on the frame 11 corresponding to the angle grinder 12, which drives the grinding head of the angle grinder 12 to extend outward. The traveling mechanism 2 includes two end plates 21, with the frame 11 located between the two end plates 21. Both ends of the frame 11 are rotatably connected to the two end plates 21. Three connecting rods 22 are evenly arranged on the outer periphery of the end plates 21, and a roller 23 is installed on the end of the connecting rod 22 away from the end plate 21. A rotary drive component 20 is provided on the end plate 21 to drive the frame 11 to rotate.

[0032] A connector is provided on the side of the end plate 21 located at the front end of the frame 11 away from the frame 11. The connector is used to connect with the pipeline robot. Specifically, the connector includes a connecting pipe 24, both ends of which are connected to flanges. One flange of the connecting pipe 24 is connected to the corresponding end plate 21 through a connecting bracket.

[0033] When grinding and removing rust from the weld seams inside the water supply pipeline, the connecting pipe 24 is connected to the pipeline robot via a flange. The pipeline robot is used as the traction power, allowing the frame 11 to move inside the water supply pipeline via its own walking mechanism 2. When it moves to the weld seam of the water supply pipeline, the drive component 13 drives the wire brush 121 of the angle grinder 12 to abut against the inner wall of the water supply pipeline, and the rotary drive component 20 drives the frame 11 to rotate, thus removing rust from the weld seams inside the water supply pipeline in a circumferential manner.

[0034] In this embodiment, the frame 11 is made of stainless steel, and is hollow inside with openings on both sides. The angle grinder 12 is hinged to the side opening of the frame 11 via a bracket, and the hinge axis of the angle grinder 12 is perpendicular to the rotation axis of its grinding head. The grinding head of the angle grinder 12 is located near the front end of the frame 11.

[0035] Reference Figure 1 and Figure 2The drive assembly 13 includes a connecting plate 131 and a traction cylinder 133. The connecting plate 131 protrudes from the outer rear end of the frame 11. Two tension springs 132 are connected to the connecting plate 131. The end of the tension spring 132 away from the connecting plate 131 is connected to the end of the angle grinder 12 near the grinding head. The tension spring 132 is used to drive the end of the angle grinder 12 near the grinding head to swing outward. When the tension spring 132 is in the initial state, the grinding head of the angle grinder 12 is set to swing outward. The traction cylinder 133 and the tension spring 132 are located on both sides of the angle grinder 12. The tail end of the traction cylinder 133 is fixed to the rear end of the frame 11, and the piston rod of the traction cylinder 133 is set towards the front end of the frame 11. The end of the piston rod of the traction cylinder 133 is connected to the end of the angle grinder 12 near the grinding head through a connecting rope 134.

[0036] In conjunction with the tension spring 132 and the traction cylinder 133, the oscillating angle grinder 12 moves inside the water supply pipe. The traction cylinder 133 drives the piston rod to retract, pulling the grinding head of the angle grinder 12 closer to the frame 11 via the connecting rope 134. This prevents the wire brush 121 at the grinding head from interfering with the inner wall of the water supply pipe during its movement, thus avoiding difficulties in its movement. When grinding is required, the traction cylinder 133 extends its piston rod, allowing the wire brush 121 at the grinding head of the angle grinder 12 to swing outward under the traction of the tension spring 132 and abut against the inner wall of the water supply pipe, facilitating subsequent grinding of the weld seams in the water supply pipe.

[0037] Reference Figure 2 and Figure 3 The frame 11 is connected to the limiting frame 111 corresponding to the connecting rope 134. The limiting frame 111 is located near the grinding head of the angle grinder 12 and is located on the side of the angle grinder 12 away from the grinding head. The limiting frame 111 is connected to the limiting tube 112 through which the connecting rope 134 passes. The connecting rope passes through the limiting tube 112, and the limiting tube 112 is used to limit and guide the connecting rope 134.

[0038] Reference Figure 1 and Figure 4 The connecting rod 22 is made of metal. When the pipe wall grinding and rust removal device is located inside the water supply pipe, the rollers 23 at the ends of the connecting rod 22 on the outer periphery of the end plate 21 are all set to abut against the inner wall of the water supply pipe. The outer periphery of the rollers 23 at the ends of the connecting rod 22 is covered with a rubber layer, which helps to improve the friction between the rollers 23 and the pipe wall.

[0039] All connecting rods 22 are fitted against the side of the end plate 21 away from the frame. Each connecting rod 22 has an elongated hole on its outer circumference, through which two connecting bolts pass. These bolts are threaded onto the end plate 21. The elongated holes and connecting bolts allow for adjustable distance between the roller 23 and the end plate 21, facilitating the adjustment of the distance between the roller 23 and the end plate 21 according to different inner diameter water supply pipes, ensuring that the roller 23 can abut against the inner wall of the water supply pipe.

[0040] Reference Figure 1 and Figure 5 The rotary drive component 20 is located on the end plate 21 at the front end of the frame 11. The rotary drive component 20 includes a geared motor 201, which is mounted on the side of the end plate 21 away from the frame 11 and has its output shaft passing through the end plate 21. The output shaft of the geared motor 201 is coaxially connected to a drive gear 202. The end shaft 110 of the frame 11 is coaxially connected to a driven gear 203, and the drive gear 202 and the driven gear 203 are meshed. Subsequently, by driving its own output shaft to rotate through the geared motor 201, the frame 11 can be driven to rotate the angle grinder 12 to perform circumferential grinding and rust removal on the weld seam of the water supply pipe.

[0041] A camera 3 is mounted on the end plate 21 at the rear of the frame 11, facing the front of the frame 11. In this embodiment, the camera 3 is a wide-angle camera. The camera 3 is connected to an external controller to acquire images of the inside of the water supply pipe and feed them back to the external controller. When performing rust removal work inside the water supply pipe, the camera 3 can acquire images of the inside of the water supply pipe and feed them back to the external controller in a timely manner. This allows operators to monitor the situation inside the water supply pipe in real time.

[0042] LED lights are installed on both sides of the end plate 21. When the pipe wall rust removal and grinding device moves inside the water supply pipe, the LED lights on the end plate 21 can provide illumination, so that the camera 3 can obtain a clearer image of the inside of the water supply pipe. At the same time, it is also convenient for external operators to observe the operation of the device inside the water supply pipe.

[0043] Reference Figure 1 and Figure 4 A connecting flange pipe 25 is also provided at the end plate 21 at the rear end of the frame 11. The connecting flange pipe 25 is used to connect external equipment, such as a dust collection device or a painting device, which helps to improve the overall function and applicability of the pipe wall grinding and rust removal device.

[0044] The implementation principle of this embodiment is as follows: After connecting the pipe wall grinding device to the pipe robot, the pipe robot pulls the device body along the water supply pipe. When it reaches the weld, the angle grinder 12 is started, and the position of the angle grinder 12 is adjusted by the drive component 13 so that the wire brush 121 of the grinding head of the angle grinder 12 contacts the weld of the pipe wall of the water supply pipe. At the same time, the rotary drive component 20 drives the frame 11 to rotate, so as to achieve grinding and rust removal at the weld, effectively improving the rust removal efficiency.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
