Description

Technical Field

[0001] This utility model relates to the field of turnout wear reduction technology, and in particular to an intelligent turnout wear reduction device. Background Technology

[0002] The main function of turnout friction reduction is to reduce the friction and wear between the wheel and rail when a train passes through the turnout, thereby extending the service life of the rails and wheels, improving traffic safety, and reducing maintenance costs. Turnouts are key components of the railway system. Due to their unique structure, trains generate significant friction when passing through them, leading to accelerated wheel and rail wear.

[0003] A friction-reducing device is a piece of equipment used to reduce wheel-rail friction and wear. It achieves this effect by forming a lubricating film on the wheel-rail contact surface. Existing friction-reducing devices have some drawbacks: traditional devices may require manual operation, cannot respond in real time to train passage through switches, and result in insufficient or uneven application of wear-resistant grease. Furthermore, manual operation increases maintenance costs and may affect the friction-reducing effect due to improper operation; some devices are also bulky and inconvenient to carry. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intelligent turnout wear reduction device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an intelligent turnout friction reduction device, comprising a proximity switch and a control box. The proximity switch is clamped onto the rail by a first clamp, and a top bolt is provided on the proximity switch. The proximity switch is pressed against the rail web by the top bolt. A material conveying pipe is provided through one end of the control box, and a coating plate is connected to the material conveying pipe. An anti-loosening fastener is bolted to the bottom of the coating plate, and the coating plate is pressed against the rail by the anti-loosening fastener. A second clamp is bolted to the bottom of the anti-loosening fastener, and the anti-loosening fastener is clamped onto the rail by the second clamp. A photovoltaic panel is fixedly installed on the cover of the control box. A paste storage tank is fixedly installed inside the control box, and an oil outlet connector is connected to the paste storage tank. The oil outlet connector is connected to a motor pump through the material conveying pipe. A controller is installed inside the control box, and a storage battery is installed inside the control box. Clamps are fixedly connected to both sides of the control box, and the control box is clamped to the rail by the clamps.

[0006] As a further description of the above technical solution:

[0007] The proximity switch is 15mm lower than the lower jaw of the rail and maintains a distance of 20-30mm from the side of the rail.

[0008] As a further description of the above technical solution:

[0009] The proximity switch uses a non-contact magnetic induction mode, with the sensing surface extending upwards within a 35mm range to ensure that it does not come into contact with the wheel during operation.

[0010] As a further description of the above technical solution:

[0011] The coating plate can be adjusted up and down. The top surface of the coating plate protrudes 5-6mm from the lower jaw of the rail to ensure that it does not come into contact with the wheel during operation. The wear-resistant grease applied to the coating plate is only applied to the side grinding surface of the rail and the wheel flange, and does not penetrate into the top of the rail.

[0012] As a further description of the above technical solution:

[0013] The control box has a narrow and long design with an installation width of 300mm. During installation, the control box is kept at a safe distance of 1.75m from the outside of the rail.

[0014] As a further description of the above technical solution:

[0015] The storage tank has a capacity of 550 mL.

[0016] As a further description of the above technical solution:

[0017] The controller is electrically connected to the battery, the controller is electrically connected to the motor pump, the battery is electrically connected to the photovoltaic panel, and the controller is wirelessly connected to the proximity switch.

[0018] This utility model has the following beneficial effects:

[0019] 1. The proximity switch and the coating plate are installed on the inside of the rail before entering the turnout. When the train passes the proximity switch, the proximity switch transmits a signal. The signal receiving system of the controller receives the signal and then issues a working command. The motor pump starts to work, and the polymer nano wear-resistant paste is squeezed out from the material outlet of the coating plate and adheres to the wheel flange. After the train enters the turnout, the wheel flange and the inner side of the rail come into contact, and a uniform lubricating strip is finally formed on the inner side of the rail to reduce the coefficient of friction and ultimately achieve the purpose of reducing wheel-rail wear.

[0020] 2. This utility model also adopts low power consumption control technology. The vibration sensor of the proximity switch detects the arrival signal of the train, wakes up the main board of the controller and the peripheral working circuit, performs the coating operation of the friction reducing agent according to the set process, and uploads information to the platform in a timely manner. The coating frequency, communication frequency and other settings can be set on the platform.

[0021] 3. Portable coating offers greater flexibility and can be used on any turnout. Each station can arrange its own use. The portable coating equipment can be automatically controlled, enabling 24-hour unattended operation, which improves safety while ensuring optimal wear reduction. Attached Figure Description

[0031] All electrical components and connectors are equipped with an industrial protection rating of IP65 or higher. Meanwhile, the controller 13 adopts a design that combines 3000V isolation technology with 1500V components to avoid the impact of electromagnetic interference from high-voltage lines on the equipment and ensure the normal operation of the equipment on site.

[0032] The height of proximity switch 1 is 15mm lower than the lower jaw of the rail and maintains a distance of 20-30mm from the side of the rail.

[0033] The proximity switch 1 adopts a non-contact magnetic induction mode, with the sensing surface extending upwards within a 35mm range to ensure that it does not come into contact with the wheel during operation.

[0034] The coating plate 6 is installed and fixed inside the rail web with high-strength anti-loosening fasteners 7. Depending on the vertical wear of the rail, the discharge plate can be adjusted up and down. The top surface of the discharge plate protrudes 5-6mm from the lower jaw of the rail and does not come into contact with the wheel during operation. The wear-resistant grease applied to the coating plate 6 is only applied to the side wear surface of the rail and the wheel flange and does not penetrate the top of the rail.

[0035] The control box 4 has a narrow and long design with an installation width of 300mm. During installation, the control box 4 must maintain a safe distance of 1.75m from the outside of the rail.

The motor pump 12 starts to work. The polymer nano wear-resistant paste is squeezed out from the material port of the coating plate 6 and adheres to the wheel flange.
