Description

Technical Field

[0001] This utility model belongs to the technical field of railway maintenance equipment, specifically relating to an integrated device for rust removal and grinding of railway rails. Background Technology

[0002] Rust removal and grinding of rails is a crucial part of railway maintenance. Currently, with the development of the railway industry, the quality requirements for rust treatment of rail surfaces are becoming increasingly stringent. Existing rust removal technologies mainly include mechanical grinding, chemical cleaning, and laser cleaning. However, each method has certain technical drawbacks: mechanical grinding uses grinding wheels or flap wheels for physical grinding, which, while low-cost, suffers from low precision, low efficiency, and high noise; chemical cleaning uses chemical agents for rust removal, which, while highly efficient, poses a high risk of environmental pollution, and wastewater collection is inconvenient and wastewater treatment is costly; laser cleaning is a relatively new technology, but its equipment investment and maintenance costs are high, it consumes a lot of energy, and its applicability is limited. Furthermore, existing rust removal equipment has poor adaptability and cannot effectively handle rails of different specifications (50kg / m to 75kg / m), especially the arc-shaped area where the rail web meets the rail top and bottom. Utility Model Content

[0003] The purpose of this invention is to solve the problems of insufficient grinding precision, low efficiency, and limited adaptability mentioned in the background technology, and to provide an integrated device for rust removal and grinding of railway rails. This device achieves efficient and precise rust removal of rails through a novel grinding structure.

[0004] The objective of this utility model is achieved through the following technical solution: An integrated device for rust removal and grinding of railway rails includes a traveling mechanism, a contour guide rail frame mounted on the traveling mechanism, and a grinding mechanism mounted on the contour guide rail frame. The contour guide rail frame is adapted to the profile of the rail and follows the changes in the rail profile. The contour guide rail frame includes a support frame, a floating frame, and guide wheels. The support frame is fixed on the traveling mechanism, and a smooth rod perpendicular to the length direction of the rail is horizontally mounted on the support frame. The floating frame is inverted U-shaped and can slide left and right on the smooth rod, with the rail located on the guide rod. Inside the floating frame, there are three sets of guide wheels. These three sets of guide wheels are installed on the inner wall of the floating frame and move along the top surface of the rail and the side walls on both sides. Support plates extend from both sides of the floating frame. The grinding mechanism is installed at the front and rear ends of the support plates. The grinding mechanism includes a grinding wheel seat, a pneumatic motor, and a grinding roller. The grinding wheel seat is used to support the pneumatic motor and the grinding roller. The grinding roller is conical, with its small diameter end located in front of the grinding direction, and its large diameter end coaxially connected to the output shaft of the pneumatic motor.

[0005] The small-diameter end of the grinding roller is a steel wire wheel, and the large-diameter end of the grinding roller is a flap wheel.

[0006] A rotating seat is installed in the middle of the support plate. A grinding disc is installed on the rotating seat to grind the arc angle of the rail. An electric motor is also installed on the rotating seat to drive the grinding disc to rotate. The rotating seat includes a support seat and an adjusting seat. An adjusting bolt is installed on the support seat to control the working angle of the adjusting seat. The grinding disc is horizontally installed on the surface of the adjusting seat.

[0007] The floating frame is equipped with a protective cover to enclose the grinding mechanism, and an air pump is installed on the protective cover.

[0008] The walking mechanism is equipped with an engine, a compressor, and a generator. The engine is connected to the compressor and the generator. The compressor provides kinetic energy to the pneumatic motor, and the engine also provides kinetic energy to the generator.

[0009] It also includes a PLC controller, which is connected to a camera. The camera is used to detect the polishing effect and upload the data to the PLC controller. The PLC controller is used to control the working speed of the polishing mechanism.

[0010] The beneficial effects of the integrated railway maintenance rail rust removal and grinding device provided by this utility model are: (1) By setting up a walking mechanism and installing a contour guide rail on the walking mechanism, the grinding mechanism can fit the track, enabling the grinding mechanism to perform stable grinding. The grinding mechanism can perform compound grinding through the grinding roller composed of a wire wheel and a flap wheel, which improves the grinding efficiency. (2) By setting a conical grinding roller, the linear velocity of the working surface of the grinding rollers of two different materials can be changed to treat the rust removal of rails of different positions and specifications. (3) By setting up a grinding disc, the dead corners that the grinding roller cannot reach can be cleaned separately, thereby ensuring the grinding effect. Attached Figure Description

[0018] like Figures 1-5 As shown, the integrated railway maintenance rail rust removal and grinding device provided in this embodiment includes a traveling mechanism 1, a contour guide rail frame 2 installed on the traveling mechanism 1, and a grinding mechanism 3 installed on the contour guide rail frame 2.

[0019] The traveling mechanism 1 is the mobile platform for the entire device. It can use existing railcars or handcarts. Its function is to enable the entire device to move on the rails and achieve continuous rust removal and grinding operations. The contour guide rail 2 is a key component for grinding. The contour guide rail 2 is adapted to the contour of the rail and follows the changes in the contour of the rail to ensure that the grinding mechanism 3 always has optimal contact with the surface of the rail. The contour guide rail frame 2 includes a support frame 21, a floating frame 22, and guide wheels 23. The support frame 21 is fixed to the traveling mechanism 1 and provides the mounting base for the floating frame 22. A smooth rod 24 perpendicular to the length direction of the rail is horizontally mounted on the support frame 21. The floating frame 22 is slidably mounted on the smooth rod 24, which provides stable sliding guidance for the floating frame 22. The floating frame 22 is inverted U-shaped, with the rail located inside the floating frame 22. This design allows the floating frame 22 to adapt to changes in the width or lateral displacement of the rail. There are three sets of guide wheels 23, which are mounted on the inner wall of the floating frame 22 and are arranged separately. The floating frame 22 moves along the top surface and side walls of the rail. Specifically, one set of guide wheels 23 contacts the top surface of the rail, while the other two sets of guide wheels 23 contact the side walls of the rail. Through the cooperation of these three sets of guide wheels 23, the floating frame 22 can accurately sense the contour changes of the rail and drive the rail to perform precise contour grinding. Support plates 25 extend from both sides of the floating frame 22. The grinding mechanism 3 is installed at both ends of the support plate 25. The grinding mechanisms 3 at both ends of the support plate 25 can perform multiple grinding operations simultaneously, or perform different grinding functions at each end, such as rough grinding at the front and fine grinding at the rear. The grinding mechanism 3 includes... The system includes a grinding wheel holder 31, a pneumatic motor 32, and a grinding roller 33. The grinding wheel holder 31 supports the pneumatic motor 32 and the grinding roller 33. The grinding roller 33 is conical, with its small-diameter end located at the front of the grinding direction. The large-diameter end of the grinding roller 33 is coaxially connected to the output shaft of the pneumatic motor 32. The conical shape of the grinding roller 33 ensures stability and precision during grinding. To ensure the grinding effect on the rails, the small-diameter end of the grinding roller 33 is a wire wheel 34. The wire wheel 34 has a strong ability to remove loose rust and surface dirt, and its flexibility allows it to better adapt to the surface contour of the rails. The large-diameter end of the grinding roller 33... The flap wheel 35 is composed of multiple layers of cloth blades, which have good elasticity and heat dissipation. In addition, since the flap wheel 35 is at the large diameter end, its selection speed is faster, enabling efficient grinding and polishing, so that the surface of the rail can achieve a higher degree of smoothness. The different rotational linear speeds of the wire wheel 34 at the small diameter end and the flap wheel 35 at the large diameter end result in different grinding degrees. The grinding parameters can be adjusted according to the rail detection. Since the grinding roller 33 is conical, when installing the grinding roller 33, its axis is arranged at a certain angle to the straight line of the rail, so that the working surface of the grinding roller 33 is in contact with the side of the steel pipe.Since the top surface of the rail is in contact with the train wheel disc, it has less rust. Therefore, this solution mainly involves rust removal from the side walls of both sides of the rail.

[0020] The arc-shaped area where the rail web meets the rail top and bottom is a cleaning dead zone. To facilitate cleaning, a rotating seat 4 is installed in the middle of the support plate 25. A grinding disc 44 for grinding the arc-shaped corner of the rail is installed on the rotating seat 4. A gap is left on the floating frame 22 for installing the rotating seat 4. An electric motor 45 is also installed on the rotating seat 4 to drive the grinding disc 44 to rotate. The rotating seat 4 includes a support base 41 and an adjusting base 42. An adjusting bolt 43 for controlling the working angle of the adjusting base 42 is installed on the support base 41. The grinding disc 44 is horizontally installed on the surface of the adjusting base 42. The electric motor 45 drives the grinding disc 44 to rotate via a universal joint, flexible shaft, or bevel gear. The universal joint, flexible shaft, or bevel gear is placed inside the support base 41. The adjusting bolt 43 can control the tilt angle of the adjusting base 42. Figure 4 As shown, the adjusting bolt 43 is fixed on the support base 41. The angle of the adjusting base 42 is controlled by two nuts that clamp the adjusting base 42, thereby adjusting the working angle between the grinding disc 44 and the cleaning dead corner to ensure grinding efficiency.

[0021] Since the entire grinding process generates a lot of dust, in order to protect the operators, the floating frame 22 is equipped with a protective cover 26 to cover the grinding mechanism 3. An air pump 27 is installed on the protective cover 26. The air pump 27 can extract the dust generated during the grinding process and discharge it to both sides of the track through an extended exhaust pipe or collect it uniformly through a dust collection box. The specific operation is adjusted according to the site environment.

[0022] To facilitate the adaptation of the entire device to environments without energy supply, the walking mechanism 1 is equipped with an engine 5, a compressor 6, and a generator 7. The engine 5 is connected to the compressor 6 and the generator 7. The compressor 6 provides kinetic energy to the pneumatic motor 32, enabling the compressor 6 to generate high-pressure gas, which powers the high-speed rotation of the grinding roller 33. At the same time, the engine 5 also provides kinetic energy to the generator 7, which in turn provides electricity to the electric motor 45 and other electrical components. The connection between the engine 5, the compressor 6, and the generator 7 is existing technology and will not be described in detail here. This integrated power system reduces dependence on external energy sources and improves the overall device's ability and flexibility in field operations.

[0023] To make the entire polishing process more convenient, a PLC controller 8 is also provided. The PLC controller 8 is connected to a camera 81, which is positioned before and after the polishing mechanism 3 to detect the polishing effect and upload the data to the PLC controller 8. The operator can evaluate the polishing effect based on the changes in the images fed back by the PLC controller 8, and then control the power of the polishing mechanism 3. Alternatively, the PLC controller 8 can automatically control the power of the polishing mechanism 3 according to the set parameters, such as reducing the moving speed of the walking mechanism 1 in severely rusted areas to enhance polishing, or increasing the polishing speed in lightly rusted areas.

[0024] The method of using this utility model is as follows: In use, the guide wheel 23 is connected to the rail, and the floating frame 22 is kept in close contact with the rail by the three guide wheels 23. This ensures the working distance between the grinding mechanism 3 and the rail, thereby ensuring the grinding accuracy. Then, the traveling mechanism 1 drives the contour guide frame 2 to travel along the rail, and the grinding mechanism 3 is used for grinding during the travel process.

[0025] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications and substitutions based on the technical solutions and inventive concepts provided by the present invention should be covered within the scope of protection of the present invention.
