Description

Technical Field

[0001] This utility model relates to a rust-preventive oil spraying device for railway rail bolt fasteners, belonging to the technical field of railway track oiling equipment. Background Technology

[0002] In railway maintenance, applying oil to railway fasteners for rust prevention is a fundamental task and a crucial aspect of safe railway operation. Because railway bolts and fasteners are constantly exposed to the outdoors, they are susceptible to corrosion due to environmental factors. This corrosion affects the strength of the bolts and fasteners, leading to poor track structure stability. Regular oiling effectively prevents corrosion, ensuring that the bolts and fasteners are in good working condition, extending their service life, and guaranteeing the safety and reliability of railway operations.

[0003] Traditional methods of applying rust-preventive oil to bolts and fasteners rely heavily on manual labor. Workers use brushes to apply the oil, which is labor-intensive, inefficient, and slows down the overall oiling process. Furthermore, due to individual differences among workers, uneven or missed areas are common, leaving rust on the bolts and fasteners and compromising railway safety. Therefore, improvements are necessary. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-rust oil spraying device for railway bolt fasteners that can effectively reduce manual labor and solve the problems of uneven application or missed application in existing manual application methods.

[0005] The technical solution of this utility model is:

[0006] A rust-preventive oil spraying device for railway rail bolt fasteners includes a frame, an oil tank, an oil spraying assembly, and a bolt sensing assembly. The device is characterized by: perforated plates symmetrically arranged on the upper surface of the frame; an oil tank mounted on the frame between the perforated plates; a traveling mechanism mounted at the bottom of the frame; an oil pump mounted on the lower surface of the frame; oil spraying assemblies mounted on the frames on both sides of the oil pump; the oil pump and oil spraying assemblies connected by connecting oil pipes; the oil pump and oil tank connected by an oil inlet pipe; and the oil spraying assembly and oil tank connected by a return oil pipe. A bolt sensing assembly is mounted on the frame in front of the oil spraying assembly. The bolt sensing assembly includes a main frame, a rack, and a sensing baffle. A rack is slidably mounted on the main frame; a swinging component is mounted on the main frame below the rack, engaging with the rack; a tension spring is mounted between one end of the rack and the main frame; a travel sensor is mounted on the other end of the rack via a buffer spring; and a sensing baffle is mounted on the main frame corresponding to the travel sensor.

[0007] The walking mechanism includes a drive shaft, a drive wheel, a driven wheel, and a drive motor. The drive shaft is movably mounted on one end of the frame via a mounting base. Drive wheels are mounted on both ends of the drive shaft. Drive wheels are movably mounted on the frame corresponding to the drive wheels via mounting bases. A drive motor is mounted on the frame on one side of the drive shaft. The drive motor's transmission shaft is connected to the drive shaft via a chain and sprocket.

[0008] The oil spraying assembly includes a solenoid valve, a branch oil pipe, and a rust-preventive oil nozzle. The solenoid valve is fixedly mounted on the frame. A branch oil pipe is fixedly mounted on the frame on one side of the solenoid valve. Rust-preventive oil nozzles are symmetrically arranged on the branch oil pipe. The rust-preventive oil nozzles are curved and have nozzles at both ends.

[0009] The swinging component includes an assembly plate, an incomplete gear, an extension rod, and a roller. The assembly plates are fixedly mounted on the main frame at intervals. Incomplete gears are movably mounted between the assembly plates via a rotating shaft. The incomplete gears mesh with a rack. An extension rod is fixedly mounted on the circumference of the incomplete gear. A fork is provided on the extension rod, and a roller is movably mounted on the fork.

[0010] The outer layer of the roller is provided with a rubber layer.

[0011] The cross-section of the induction baffle is shaped like a "┌".

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] This rust-preventive oil spraying device for railway bolt fasteners heats the oil through a heating pipe and then returns it to the oil tank via a solenoid valve and a return pipe, preventing the oil in the pipe from cooling down. A drive motor, in conjunction with a chain and sprocket, drives the drive shaft to rotate, which in turn drives the drive wheel. This, in turn, drives the rust-preventive oil spraying device along the railway track via the drive and driven wheels. The roller contacts the protruding bolt fasteners on the side of the rail, causing the extension rod to rotate around its axis. During this rotation, the extension rod drives the incomplete gear to rotate synchronously. Because the incomplete gear meshes with the rack, it causes the rack to slide away from the tension spring along the axial direction of the slide groove. During this sliding, the rack stretches and stores tension spring energy. Simultaneously, the rack, through a buffer spring, pushes the travel sensor against the sensing baffle. The sensor transmits the bolt positioning signal to the programmable controller. Upon receiving the signal, the programmable controller opens the solenoid valve, which delivers rust-preventive oil to the branch oil pipe and the rust-preventive oil nozzle. The oil is then sprayed from the nozzle. As the rust-preventive oil spraying device travels continuously along the railway track at a certain speed, the sprayed rust-preventive oil covers the outer surface of the bolt fastener. After spraying, the solenoid valve closes. When the roller passes over the bolt fastener, it resets under the elastic force of the tension spring, awaiting the next bolt fastener identification. When the roller contacts the next bolt fastener, the oil is sprayed from the nozzle again following the above process, enabling continuous and uninterrupted rust-preventive oil spraying. This rust-preventive oil spraying device effectively reduces manual labor and solves the problems of uneven application or missed areas in existing manual application methods.

[0021] As attached Figure 1-6 As shown

[0022] The anti-rust oil spraying device for railway bolt fasteners includes a frame 1, an oil tank 2, an oil spraying assembly, and a bolt sensing assembly. The upper surface of the frame 1 is symmetrically provided with perforated plates 3. The oil tank 2 is installed on the frame 1 between the perforated plates 3. Heating tubes 4 are symmetrically arranged inside the oil tank 2. During operation, the heating tubes 4 are used to heat the anti-rust oil in the oil tank 2.

[0023] The frame 1 is equipped with a traveling mechanism at its bottom. The traveling mechanism includes a drive shaft 5, a drive wheel 6, a driven wheel 7, and a drive motor 8. The drive shaft 5 is movably mounted on one end of the frame 1 via a mounting base. Drive wheels 6 are fixedly mounted on both ends of the drive shaft 5. Drive wheels 7 are movably mounted on the frame 1 corresponding to the drive wheels 6 via mounting bases. The drive motor 8 is fixedly mounted on the frame 1 on one side of the drive shaft 5. The drive shaft of the drive motor 8 is connected to the drive shaft 5 via a chain and sprocket. During operation, the drive shaft of the drive motor 8 drives the drive shaft 5 to rotate via the chain and sprocket. The drive shaft 5 synchronously drives the drive wheels 6 to rotate, thereby driving the frame 1 to move along the rail through the cooperation of the drive wheels 6 and the driven wheels 7.

[0024] An oil pump 9 is fixedly installed on the lower surface of the frame 1. An oil spraying assembly is installed on the frame 1 on both sides of the oil pump 9. The oil spraying assembly includes a solenoid valve 10, a branch oil pipe 11, and a rust-preventive oil nozzle 12. The solenoid valve 10 is fixedly installed on the frame 1. A branch oil pipe 11 is fixedly installed on the frame 1 on one side of the solenoid valve 10. Rust-preventive oil nozzles 12 are symmetrically arranged on the branch oil pipe 11. The rust-preventive oil nozzles 12 are curved. Nozzles 13 are provided at both ends of the rust-preventive oil nozzles 12. During operation, because the rust-preventive oil nozzles 12 are curved, the spray fan formed by the nozzles 13 at both ends of the rust-preventive oil nozzles 12 has a wider range, which can achieve all-round spraying of bolt fasteners and avoid missed areas of bolt fasteners.

[0025] The oil pump 9 is connected to the spraying assembly via the connecting oil pipe 14, the oil pump 9 is connected to the oil tank 2 via the oil inlet pipe 15, and the spraying assembly is connected to the oil tank 2 via the oil return pipe 16. During operation, the rust-preventive oil in the oil tank 2 is conveniently transported to the oil pump 9 via the oil inlet pipe 15, and the rust-preventive oil in the oil pump 9 is transported to the solenoid valves 10 of each spraying assembly via the connecting oil pipe 14. The solenoid valves 10 then transport the oil to the branch oil pipes 11 and the rust-preventive oil nozzles 12, and spray it out from the nozzles 13 of the rust-preventive oil nozzles 12. When no spraying operation is being performed, the solenoid valves 10 transport the rust-preventive oil to the oil tank 2 via the oil return pipe 16 for reheating to prevent the rust-preventive oil from cooling and solidifying.

[0026] A bolt sensing assembly is mounted on the frame 1 in front of the oil injection assembly. The bolt sensing assembly includes a main frame 17, a rack 18, and a sensing baffle 19. The rack 18 is slidably mounted on the main frame 17 via a slide groove. A swinging component is mounted on the main frame 17 below the rack 18, and the swinging component meshes with the rack 18. The swinging component includes an assembly plate 20, an incomplete gear 21, an extension rod 22, and a roller 24. The assembly plates 20 are fixedly mounted on the main frame 17 at intervals, and the assembly plates 20 are connected by a rotating shaft 29. An incomplete gear 21 is movably mounted and meshes with a rack 18. An extension rod 22 is fixedly mounted on the circumference of the incomplete gear 21, and a fork 23 is fixedly mounted on the extension rod 22. A roller 24 is movably mounted on the fork 23, and the outer layer of the roller 24 is covered with a rubber layer. A tension spring 25 is installed between one end of the rack 18 and the main frame 17, and a stroke sensor 28 (model LX19-001) is installed at the other end of the rack 18 via a buffer spring 26. A sensing baffle 19 is provided on the main frame 17 corresponding to sensor 28. The cross-section of sensing baffle 19 is "┌". During operation, when roller 24 contacts bolt fastener, it is blocked by bolt fastener. Roller 24 drives extension rod 22 to rotate around shaft 29. During the rotation, extension rod 22 drives incomplete gear 21 to rotate synchronously. Since incomplete gear 21 meshes with rack 18, incomplete gear 21 drives rack 18 to slide away from tension spring 25 along the axial direction of slide groove. During the sliding process, rack 18 drives tension spring 25 to stretch and store force. At the same time, rack 18 pushes stroke sensor 28 to contact sensing baffle 19 through buffer spring 26. Buffer spring 26 can provide a certain buffer stroke between rack 18 and stroke sensor 28 to avoid excessive squeezing of stroke sensor 28 by rack 18. After stroke sensor 28 contacts sensing baffle 19, the bolt positioning signal can be transmitted through stroke sensor 28.

[0027] The anti-rust oil spraying device for railway bolt fasteners is equipped with a programmable controller (model PLCS7-800). A storage battery 27 is installed on the frame 1 of the anti-rust oil spraying device. The programmable controller is electrically connected to the storage battery 27, drive motor 8, heating tube 4, solenoid valve 10 and stroke sensor 28. The programmable controller controls the drive motor 8, heating tube 4, solenoid valve 10 and stroke sensor 28 to operate in a sequential and orderly manner.

[0028] When the rust-preventive oil spraying device for railway bolt fasteners is in operation, it is first placed on the railway rail, and then an appropriate amount of rust-preventive oil is poured into the oil tank 2. The heating tube 4 is started by the program controller to heat the oil. After the oil in the oil tank 2 has been heated for a period of time, the program controller controls the oil pump 9 to start. The oil pump 9 draws the rust-preventive oil from the oil tank 2 and transports it back to the oil tank 2 through the solenoid valve 10 and the return oil pipe 16 to prevent the rust-preventive oil in the oil pipe from cooling down.

[0029] The drive motor 8 is started by the programmable controller. The drive motor 8 drives the drive shaft 5 to rotate through the chain and sprocket. The drive shaft 5 drives the drive wheel 6 to rotate synchronously. Thus, the drive wheel 6 and the driven wheel 7 drive the anti-rust oil spraying device to move along the rail. When the roller 24 contacts the bolt fastener protruding from the side of the rail, it is blocked by the bolt fastener. The roller 24 drives the extension rod 22 to rotate around the rotating shaft 29. During the rotation of the extension rod 22, it drives the incomplete gear 21 to rotate synchronously. Since the incomplete gear 21 meshes with the rack 18, the incomplete gear 21 drives the rack 18 to slide away from the tension spring 25 along the axial direction of the slide groove. During the sliding process, the rack 18 drives the tension spring 25 to stretch and store force. At the same time, the rack 18 pushes the stroke sensor 28 and the sensing baffle 19 through the buffer spring 26. The bolt positioning signal is transmitted to the programmable controller via the stroke sensor 28. Upon receiving the bolt positioning signal, the programmable controller controls the solenoid valve 10 to open. The solenoid valve 10 delivers rust-preventive oil to the branch oil pipe 11 and the rust-preventive oil nozzle 12, and sprays it out from the nozzle 13 of the rust-preventive oil nozzle 12. As the rust-preventive oil spraying device moves continuously on the railway track at a certain speed, the sprayed rust-preventive oil will cover the outer surface of the bolt fastener. After the rust-preventive oil nozzle 12 has finished spraying, the solenoid valve 10 closes. When the roller 24 passes over the bolt fastener, it will reset under the elastic force of the tension spring 25 to wait for the next bolt fastener recognition. When the roller 24 contacts the next bolt fastener, the oil is sprayed out from the nozzle 13 again according to the above process, realizing the continuous and uninterrupted spraying of rust-preventive oil by the rust-preventive oil spraying device.
