Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, and in particular to a rust removal and grinding equipment for railway line maintenance. Background Technology

[0002] Railway tracks are the core load-bearing foundation of railway transportation, typically consisting of two parallel steel rails fixed to sleepers. Ballast is laid beneath the sleepers, and the tracks, in conjunction with switches, allow trains to travel without turning. Because tracks are constantly exposed to the natural environment, enduring wind, sun, and rain erosion, corrosion is widespread on the rail surfaces. The sides of the rails are particularly susceptible to corrosion due to the combined effects of stress transmission and environmental contact. Without regular cleaning, corrosion accelerates rail aging and shortens the track's lifespan.

[0003] However, most existing grinding equipment has a fixed grinding roller structure, and the pressure of its contact with the rail surface cannot be automatically adjusted according to the rust protrusion. When encountering hard rust protrusions, the grinding roller is unable to generate sufficient grinding pressure, resulting in the rust protrusions not being completely removed. The remaining rust protrusions will still affect the safety of train operation.

[0004] In view of this, we have studied and improved the existing problems to provide a rust removal and grinding equipment for railway line maintenance. The aim is to solve the problems and improve the practical value through this technology. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a rust removal and grinding device for railway line maintenance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rust removal and grinding device for railway line maintenance, comprising a car plate, with grinding mechanisms and cleaning mechanisms provided on both sides of the car plate, the grinding mechanism comprising a guide rail welded to the top of the car plate, a groove provided at the bottom end of the guide rail, a slider sliding inside the groove, a rotating rod A rotatably provided inside the slider, a grinding roller installed on the outer wall of the rotating rod A, a connecting rod fixed to one side of the slider, a pull plate fixed to one end of the connecting rod, a fixing plate fixed inside the guide rail, and a spring A fixed between the fixing plate and the pull plate; The cleaning mechanism includes a rotating rod B that rotates on the side wall of the vehicle panel. An eccentric wheel is fixed to the top of the rotating rod B. A driven plate is sleeved on the top of the eccentric wheel. A horizontal tube is fixed to the top of the vehicle panel. Piston rods that slide inside the horizontal tubes are fixed to both sides of the driven plate. An air intake pipe and an exhaust pipe are connected to the outer wall of the piston rod. One end of the exhaust pipe is connected to a composite pipe. A nozzle A is connected to the outer wall of the composite pipe. A warning mechanism is provided above the vehicle board. The warning mechanism includes a branch pipe connected to the top of the exhaust pipe. The side wall of the branch pipe is connected to an exhaust pipe. A circular plate rotates inside the exhaust pipe. Multiple sets of whistles are installed on the surface of the circular plate. A blocking plate rotates inside the exhaust pipe. A toothed rod A is fixed at the top of the pull plate. An auxiliary mechanism is provided above the composite pipe.

[0007] Preferably, the guide rail has a motor-driven rotating shaft inside, a bevel gear A is sleeved on the top of the rotating rod A, a bevel gear B is embedded in the outer wall of the rotating shaft, an L-shaped plate is fixed on one side of the slider, and one end of the L-shaped plate is sleeved on the outer wall of the rotating shaft.

[0008] Preferably, a cleaning roller is installed on the outer wall of the rotating rod B, and a brush is provided on the outer wall of the cleaning roller.

[0009] Preferably, the composite pipe is divided into two independent chambers along its length, one chamber being an airflow chamber for conveying airflow and the other chamber being a liquid storage chamber for storing rust remover.

[0010] Preferably, both the outer walls of the rotating rod A and the rotating rod B are fitted with transmission wheels, and the two sets of transmission wheels are connected by a belt drive.

[0011] Preferably, a gear is fixed to the top of the blocking plate, and the rack A meshes with the gear.

[0012] Preferably, the auxiliary mechanism includes a vertical pipe connected to the outer wall of the composite pipe, a pressure plate sliding inside the vertical pipe, a spring B inside the vertical pipe, a connecting pipe connecting the composite pipe and the vertical pipe, a valve body sleeved on the outer wall of the connecting pipe, and a nozzle B connected to the outer wall of the composite pipe.

[0013] Preferably, one end of the spring B is fixedly connected to the top of the pressure plate, and the other end of the spring B is fixedly connected to the inner wall of the vertical tube.

[0014] Preferably, a valve stem is rotatably mounted on the surface of the valve body, and a toothed rod B is fixed to the side wall of the toothed rod A, with one end of the toothed rod B meshing with the top end of the valve stem.

[0015] Preferably, the nozzles B are symmetrically arranged at the bottom end of the composite tube, and the spraying ends of the nozzles B face the outer walls of the grinding roller.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention addresses the issue of hard, protruding rust on the rail surface during grinding. The rust exerts an outward pushing force on the grinding roller, causing it to move outward along the rail side. The grinding roller, via rotating rod A, drives a slider to slide along the groove at the bottom of the guide rail away from the fixed plate. The slider, through a connecting rod, simultaneously moves a pulling plate. Under the fixed limiting effect of the fixed plate, the pulling plate pulls spring A, causing elastic deformation. The reaction force generated by spring A acts in the opposite direction on the grinding roller, increasing the pressure of the grinding roller against the rail surface. This allows for more thorough grinding and removal of hard, protruding rust, ensuring uniform and thorough grinding of the rail side. The grinding pressure is automatically increased without manual intervention, efficiently removing stubborn rust and avoiding residual rust due to untimely manual adjustments, further improving the flatness of the rail surface. Simultaneously, it effectively avoids the problem of missed grinding caused by gaps between the grinding roller and the rail.

[0017] 2. This invention utilizes a cleaning roller to clean the surface of the polished rail, quickly removing rust and impurities generated during polishing and preventing secondary adhesion of rust to affect the rust removal effect. Simultaneously, the rotating rod B drives the eccentric wheel to rotate, and the rotation of the eccentric wheel pushes the driven plate to move back and forth. The driven plate drives the piston rods on both sides to move in a reciprocating motion along the inside of the horizontal tube, causing the suction pipe connected to the outer wall of the piston rod to draw in air and the exhaust pipe to discharge high-pressure airflow. Thus, the high-pressure airflow sprayed through the nozzle A can blow away the fine rust dust remaining after brush cleaning, achieving progressive cleaning from coarse cleaning to fine cleaning and improving the cleanliness of the rail surface.

[0018] 3. In this invention, when the grinding roller moves along with the raised rust on the surface of the rail, the pull plate drives the rack A to move synchronously. The rack A drives the gear to rotate, which in turn drives the blocking plate in the exhaust pipe to rotate, thus releasing the blockage of the exhaust pipe. At this time, part of the high-pressure airflow in the exhaust pipe will enter the exhaust pipe through the branch pipe. The airflow impacts the whistle on the surface of the circular plate in the exhaust pipe and emits a whistle. The sound emitted by the whistle can provide timely warning of the raised rust, reminding the operator to pay attention. This makes it easier for the staff to push the car plate back and forth at this position several times, thereby improving the rust removal effect of the raised rust.

[0019] 4. In this invention, airflow enters the interior of the vertical pipe through the connecting pipe, pushing the pressure plate downwards along the vertical pipe. The pressure plate then squeezes the liquid storage chamber of the composite pipe, causing the rust remover in the liquid storage chamber to be sprayed onto both sides of the grinding roller through nozzle B. The rust remover not only makes full contact with the grinding surface, enhancing the rust removal effect, but also lubricates and cools the high-speed rotating grinding roller, effectively extending its service life. When encountering a protruding line during grinding, the toothed rod A synchronously drives the toothed rod B on the side wall to move. When the toothed rod B moves, it drives the valve rod to rotate, changing the opening degree of the valve body, further increasing the amount of gas entering the vertical pipe, thereby increasing the thrust on the pressure plate and causing more rust remover to be discharged from the liquid storage chamber. This adapts to the increased grinding difficulty of protruding parts, ensuring thorough rust removal of protruding parts. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] See Figures 1 to 8 As shown, the present invention provides a rust removal and grinding device for railway line maintenance, including a car plate 1. Grinding mechanism and cleaning mechanism are provided on both sides of the car plate 1. The grinding mechanism includes a guide rail 21 welded to the top of the car plate 1. A groove 22 is provided at the bottom of the guide rail 21. A slider 23 slides inside the groove 22. A rotating rod A24 is rotatably provided inside the slider 23. A grinding roller 25 is installed on the outer wall of the rotating rod A24. A connecting rod 26 is fixed on one side of the slider 23. A pull plate 27 is fixed at one end of the connecting rod 26. A fixing plate 213 is fixed inside the guide rail 21. A spring A28 is fixed between the fixing plate 213 and the pull plate 27. It should be noted that when grinding and removing rust from the rails of a railway line, the car body 1 is first placed on the surface of the rail, and then the motor is started. The motor drives the rotating shaft 29 to rotate, and the rotating shaft 29 drives the bevel gear B211 embedded in its outer wall to rotate synchronously. Since the bevel gear A210 and the bevel gear B211 mesh with each other, the bevel gear B211 drives the bevel gear A210 sleeved on the top of the rotating rod A24 to rotate. The bevel gear A210 then drives the rotating rod A24 to rotate synchronously, and finally drives the grinding roller 25 on the outer wall of the rotating rod A24 to rotate, thereby realizing the grinding and rust removal operation on both sides of the rail. In the initial operating state, the two sets of grinding rollers 25, under the tension force of spring A28, can closely adhere to the side of the rail, ensuring the initial grinding fit and basic rust removal effect. When hard protruding rust is encountered on the rail surface during grinding, the protruding rust will exert an outward pushing force on the grinding rollers 25, causing the grinding rollers 25 to move outward along the side of the rail. The grinding rollers 25 then drive the slider 23 to slide along the groove 22 at the bottom of the guide rail 21 away from the fixed plate 213 via the rotating rod A24. The slider 23 drives the pull plate 27 to move synchronously via the connecting rod 26. Under the fixed limiting action of the fixed plate 213, the pull plate 27 will... When the spring A28 is pulled, it undergoes elastic deformation. The reaction force generated by the spring A28 is then transmitted through the pull plate 27, connecting rod 26, slider 23, and rotating rod A24 to the grinding roller 25. This increases the pressure of the grinding roller 25 against the rail surface, thereby more thoroughly grinding away hard, protruding rust. This ensures the uniformity and thoroughness of the grinding on the side of the rail. The grinding pressure can be automatically increased without manual intervention, which can efficiently remove stubborn rust and avoid the protrusion residue caused by untimely manual adjustment. This further improves the flatness of the rail surface. At the same time, it effectively avoids the problem of missed grinding caused by the gap between the grinding roller 25 and the rail.

[0024] The cleaning mechanism includes a rotating rod B31 that rotates on the side wall of the vehicle plate 1. An eccentric wheel 33 is fixed at the top of the rotating rod B31. A driven plate 34 is sleeved on the top of the eccentric wheel 33. A horizontal tube 35 is fixed at the top of the vehicle plate 1. Piston rods 36 that slide inside the horizontal tube 35 are fixed on both sides of the driven plate 34. An air intake pipe 37 and an exhaust pipe 38 are connected to the outer wall of the piston rod 36. One end of the exhaust pipe 38 is connected to a composite pipe 39. A nozzle A310 is connected to the outer wall of the composite pipe 39. It should be noted that during the rotation of the rotating rod A24, the rotating rod A24 drives the rotating rod B31 to rotate synchronously through the cooperation of the transmission wheel and the pull belt sleeved on the outer wall. The rotating rod B31 drives the cleaning roller 32 on its outer wall to rotate. The cleaning roller 32 uses the brush on the outer wall to simultaneously clean the surface of the polished rail, quickly removing rust and impurities generated during polishing and preventing secondary adhesion of rust to avoid affecting the rust removal effect. On the other hand, the rotating rod B31 drives the eccentric wheel 33 at the top to rotate. During the rotation of the eccentric wheel 33, the driven plate 34 is pushed to reciprocate. The driven plate 34 drives the piston rods 36 on both sides to reciprocate along the inside of the horizontal tube 35, causing the suction pipe 37 connected to the outer wall of the piston rod 36 to draw in air and the exhaust pipe 38 to discharge high-pressure airflow. The high-pressure airflow is sprayed out from the nozzle A310 through the composite pipe 39 at one end of the exhaust pipe 38. By delivering high-pressure airflow into the airflow chamber separated inside the composite pipe 39, the high-pressure airflow sprayed out by the nozzle A310 can blow away the fine rust dust remaining after brush cleaning, realizing progressive cleaning from coarse cleaning to fine cleaning and improving the cleanliness of the rail surface.

[0025] A warning mechanism is provided above the vehicle plate 1. The warning mechanism includes a branch pipe 41 connected above the exhaust pipe 38. The side wall of the branch pipe 41 is connected to an exhaust pipe 42. A circular plate 43 rotates inside the exhaust pipe 42. Multiple sets of whistles 44 are installed on the surface of the circular plate 43. A blocking plate 46 rotates inside the exhaust pipe 42. A toothed rod A45 is fixed at the top of the pull plate 27. It should be noted that when the grinding roller 25 moves along with the raised rust on the rail surface, the pull plate 27 connected to the slider 23 in the grinding mechanism will move synchronously, thereby driving the toothed rod A45 at the top of the pull plate 27 to move synchronously. Since the toothed rod A45 and the gear 47 mesh with each other, the toothed rod A45 will drive the gear 47 to rotate, and the gear 47 will drive the blocking plate 46 in the air outlet pipe 42 to rotate, so that the blocking plate 46 releases the blockage of the air outlet pipe 42. At this time, part of the high-pressure airflow in the exhaust pipe 38 will enter the air outlet pipe 42 through the branch pipe 41. The airflow impacts the whistle 44 on the surface of the circular plate 43 in the air outlet pipe 42 and emits a whistle. The sound emitted by the whistle 44 can provide timely warning of the raised rust, reminding the operator to pay attention, so that the staff can push the car plate 1 back and forth in this position several times, thereby improving the rust removal effect of the raised rust. Furthermore, when the wear of the grinding roller 25 reaches the threshold, the displacement of the pull plate 27 and the toothed bar A45 will change, which in turn will change the opening of the blocking plate 46, causing a significant difference in the loudness of the whistle. The significant change in the loudness of the whistle can provide real-time early warning of the wear status of the grinding roller 25, reminding the operator to replace the grinding roller 25 in time, effectively avoiding the impact of excessive wear of the grinding roller 25 on the rust removal effect or damage to the rail base.

[0026] An auxiliary mechanism is provided above the composite pipe 39.

[0027] In an optional embodiment: the guide rail 21 is internally equipped with a motor-driven rotating shaft 29, the top of the rotating rod A24 is fitted with a bevel gear A210, the outer wall of the rotating shaft 29 is fitted with a bevel gear B211, and one side of the slider 23 is fixed with an L-shaped plate 212, one end of the L-shaped plate 212 is fitted onto the outer wall of the rotating shaft 29.

[0028] In an optional embodiment: a cleaning roller 32 is mounted on the outer wall of the rotating rod B31, and the outer wall of the cleaning roller 32 is provided with a brush.

[0029] In an optional embodiment, the interior of the composite pipe 39 is divided along its length to form two independent chambers, one of which is an airflow chamber for conveying airflow and the other is a liquid storage chamber for storing rust remover.

[0030] In an optional embodiment: both the outer walls of the rotating rod A24 and the rotating rod B31 are fitted with transmission wheels, and the two sets of transmission wheels are connected by a belt drive.

[0031] In an optional embodiment: a gear 47 is fixed to the top of the blocking plate 46, and the rack A45 meshes with the gear 47.

[0032] In an optional embodiment: the auxiliary mechanism includes a vertical pipe 51 connected to the outer wall of the composite pipe 39, a pressure plate 52 sliding inside the vertical pipe 51, a spring B53 inside the vertical pipe 51, a connecting pipe 54 connecting the composite pipe 39 and the vertical pipe 51, a valve body 55 sleeved on the outer wall of the connecting pipe 54, and a nozzle B58 connected to the outer wall of the composite pipe 39.

[0033] In an optional embodiment: one end of spring B53 is fixedly connected to the top of pressure plate 52, and the other end of spring B53 is fixedly connected to the inner wall of vertical tube 51.

[0034] In an optional embodiment: a valve stem 56 is rotatably mounted on the surface of the valve body 55, and a toothed bar B57 is fixed to the side wall of the toothed bar A45, with one end of the toothed bar B57 meshing with the top end of the valve stem 56.

[0035] In an optional embodiment: the nozzles B58 are symmetrically arranged at the bottom end of the composite tube 39, with the spraying ends of the nozzles B58 facing both sides of the outer wall of the grinding roller 25.

[0036] It should be noted that during the process of airflow entering the airflow chamber of composite pipe 39, another part of the airflow enters the interior of vertical pipe 51 through connecting pipe 54, pushing pressure plate 52 to move downward along vertical pipe 51. Pressure plate 52 then squeezes the liquid storage chamber of composite pipe 39, causing the rust remover in the liquid storage chamber to be sprayed onto both sides of grinding roller 25 through nozzle B58. The rust remover can not only fully contact the grinding surface to help enhance the rust removal effect, but also lubricate and cool the high-speed rotating grinding roller 25, effectively extending the service life of grinding roller 25. When encountering a line protrusion during grinding, toothed rod A45 synchronously drives toothed rod B57 on the side wall to move. Since toothed rod B57 meshes with valve rod 56, the movement of toothed rod B57 drives valve rod 56 to rotate, changing the opening degree of valve body 55, further increasing the amount of gas entering the interior of vertical pipe 51, thereby increasing the thrust on pressure plate 52, causing more rust remover to be discharged from the liquid storage chamber, in order to meet the increased grinding difficulty of protruding parts and ensure thorough rust removal of protruding parts. Additionally, it should be noted that when it is necessary to replenish the rust remover inside the composite pipe 39, the operator can manually close the valve on the surface of the connecting pipe 54 and then open the liquid inlet on the surface of the composite pipe 39. This allows for timely replenishment of the rust remover into the storage chamber. At the same time, the pressure relief valve on the outer wall of the vertical pipe 51 is opened. Under the elastic potential energy of the spring B53, the spring B53 drives the pressure plate 52 to reset and squeezes out the excess gas inside the vertical pipe 51, thus facilitating subsequent continuous liquid spraying.

[0037] Working principle: When grinding and removing rust from the rails of a railway line, the car plate 1 is first placed on the surface of the rail, and then the motor is started. The motor drives the rotating shaft 29 to rotate, and the rotating shaft 29 drives the bevel gear B211 embedded in its outer wall to rotate synchronously. Since the bevel gear A210 and the bevel gear B211 mesh with each other, the bevel gear B211 drives the bevel gear A210 sleeved on the top of the rotating rod A24 to rotate. The bevel gear A210 then drives the rotating rod A24 to rotate synchronously, and finally drives the grinding roller 25 on the outer wall of the rotating rod A24 to rotate, thereby realizing the grinding and rust removal operation on both sides of the rail. In the initial working state, the two sets of grinding rollers 25 can fit tightly against the side of the rail under the tension force of spring A28, ensuring the initial grinding fit and basic rust removal effect. When hard protruding rust is encountered on the surface of the rail during the grinding process, the protruding rust will generate an outward pushing force on the grinding rollers 25, causing the grinding rollers 25 to move outward along the side of the rail. The grinding rollers 25 then drive the slider 23 to slide along the groove 22 at the bottom of the guide rail 21 away from the fixed plate 213 through the rotating rod A24. The slider 23 drives the pull plate 27 to move synchronously through the connecting rod 26. Under the fixed limiting action of the fixed plate 213, the pull plate 27 will pull the spring A28 to undergo elastic deformation. The reaction force generated by the spring A28 will act in the opposite direction on the grinding rollers 25 through the pull plate 27, connecting rod 26, slider 23 and rotating rod A24, increasing the pressing pressure of the grinding rollers 25 on the surface of the rail. As the rotating rod A24 rotates, the rotating rod A24 drives the rotating rod B31 to rotate synchronously through the cooperation of the transmission wheel and the pull belt on the outer wall. The rotating rod B31 drives the cleaning roller 32 on its outer wall to rotate. The cleaning roller 32 uses the brush on the outer wall to clean the surface of the polished rail synchronously, quickly removing the rust and impurities generated during polishing, and avoiding secondary adhesion of rust to affect the rust removal effect. On the other hand, the rotating rod B31 drives the eccentric wheel 33 at the top to rotate. During the rotation of the eccentric wheel 33, it pushes the driven plate 34 to move back and forth. The driven plate 34 drives the piston rods 36 on both sides to move back and forth along the inside of the horizontal tube 35. This causes the suction pipe 37 connected to the outer wall of the piston rod 36 to draw in air and the exhaust pipe 38 to discharge high-pressure airflow. The high-pressure airflow is sprayed out from the nozzle A310 through the composite pipe 39 at one end of the exhaust pipe 38 and is delivered to the airflow chamber separated inside the composite pipe 39. When the grinding roller 25 moves along with the raised rust on the rail surface, the pull plate 27 connected to the slider 23 in the grinding mechanism will move synchronously, thereby driving the toothed rod A45 at the top of the pull plate 27 to move synchronously. Since the toothed rod A45 and the gear 47 mesh with each other, the toothed rod A45 will drive the gear 47 to rotate, and the gear 47 will drive the blocking plate 46 in the air outlet pipe 42 to rotate, so that the blocking plate 46 releases the blockage of the air outlet pipe 42. At this time, part of the high-pressure airflow in the exhaust pipe 38 will enter the air outlet pipe 42 through the branch pipe 41. The airflow impacts the whistle 44 on the surface of the circular plate 43 in the air outlet pipe 42 and emits a whistle. The sound emitted by the whistle 44 can provide timely warning of the raised rust, reminding the operator to pay attention, so that the staff can push the car plate 1 back and forth in this position several times, thereby improving the rust removal effect of the raised rust. Furthermore, when the wear of the grinding roller 25 reaches the threshold, the displacement of the pull plate 27 and the toothed bar A45 will change, which in turn will change the opening of the blocking plate 46, causing a significant difference in the loudness of the whistle. The significant change in the loudness of the whistle can provide a real-time warning of the wear status of the grinding roller 25, reminding the operator to replace the grinding roller 25 in time, effectively avoiding the rust removal effect or damage to the rail base due to excessive wear of the grinding roller 25. During the process of airflow entering the airflow chamber of composite pipe 39, another part of the airflow enters the interior of vertical pipe 51 through connecting pipe 54, pushing pressure plate 52 to move downward along vertical pipe 51. Pressure plate 52 then squeezes the liquid storage chamber of composite pipe 39, causing the rust remover in the liquid storage chamber to be sprayed onto both sides of grinding roller 25 through nozzle B58. When encountering a line protrusion during grinding, toothed rod A45 synchronously drives toothed rod B57 on the side wall to move. Since toothed rod B57 meshes with valve rod 56, the movement of toothed rod B57 drives valve rod 56 to rotate, changing the opening degree of valve body 55, further increasing the amount of gas entering the interior of vertical pipe 51, thereby increasing the thrust on pressure plate 52, and causing more rust remover to be discharged from the liquid storage chamber.
