Description

Technical Field

[0001] This utility model belongs to the field of railway maintenance technology, specifically a slope cleaning device for railway maintenance. Background Technology

[0002] Railway slopes are an important component of railway track beds, primarily formed by the accumulation of ballast, used to stabilize the track bed structure and ensure drainage performance. With increasing railway maintenance demands, various types of machinery and equipment for track bed maintenance have been gradually applied. However, existing equipment is mostly focused on cleaning the track bed surface or adjusting the overall ballast, lacking specific design for slope cleaning operations. This leads to problems such as ballast compaction and blockage of drainage channels, affecting track stability and drainage effectiveness. Furthermore, existing equipment has limitations in terms of operational efficiency, automation, and adaptability to complex terrain.

[0003] A railway ballast slab slab clearing machine, with publication number CN116590968B and publication date November 21, 2023, is described. This device includes a height adjustment component and a stone-removing component, and is suitable for small-scale, localized ballast clearing operations. It features a compact structure and flexible operation. However, it is mainly used for leveling operations in the central area of ​​the ballast bed and lacks the ability to perform deep cleaning and screening of slope areas. Furthermore, its stone-removing component can only move in a fixed direction, which limits its cleaning and screening effect when dealing with complex accumulation conditions on slope areas.

[0004] The above situation indicates that current railway maintenance equipment on the market still has significant shortcomings in slope cleaning and screening, lacking targeted, efficient, and automated solutions. Therefore, this utility model provides a slope cleaning and screening device for railway maintenance to overcome the deficiencies of existing technology and achieve more professional and adaptable slope cleaning and screening operations.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1: This utility model provides a slope cleaning and screening device for railway maintenance, the specific implementation of which is described in conjunction with the appendix. Figure 1 To be continued Figure 5 Please provide a detailed explanation. For example... Figure 1 As shown, the device mainly includes a frame 1, an adjustment mechanism 3, a screening assembly 6, and a drive mechanism 11. The components are combined into a whole system through clear connection relationships and installation methods to achieve efficient screening operations in railway slope areas.

[0028] The frame 1 serves as the main support for the entire device, constructed from high-strength steel to provide sufficient rigidity and stability to support all functional modules. Wheels 2 are mounted at the bottom of the frame 1, fixedly connected to it via axles, enabling smooth movement on railway track slopes. An adjustment mechanism 3 is installed in the middle of the frame 1, comprising a lifting rod 4 and an angle adjustment plate 5. The lifting rod 4 is connected to the frame 1 via a threaded connection, with the angle adjustment plate 5 fixed to its top. The threaded design of the lifting rod 4 allows operators to adjust the height by rotating it, thereby changing the height of the angle adjustment plate 5 to meet the needs of different terrain conditions. The angle adjustment plate 5 is connected to the screening assembly 6 via a hinge. The hinge design allows the angle adjustment plate 5 to swing within a certain range to adapt to changes in slope angle. A groove is formed on the surface of the angle adjustment plate 5, with a locking bolt inside. After angle adjustment, the locking bolt secures the angle adjustment plate 5 in the appropriate position, ensuring the stability of the screening assembly 6 during operation.

[0029] The shaving assembly 6 is the core component of this device, comprising a ballast shovel 7, a vibrator 8, and a ballast guide trough 9. The ballast shovel 7 has an arc-shaped structure with a serrated edge at the front end. The tooth spacing is 10mm to 15mm, and the tooth depth is 5mm to 8mm. This design enhances the ballast shovel 7's ability to cut into the ballast deposit layer while avoiding insufficient cutting force due to excessive tooth spacing or accelerated wear due to excessive tooth spacing. The vibrator 8 is bolted to the rear end of the ballast shovel 7. The vibrator 8 contains an eccentric shaft with a rotational speed range of 1200r / min to 1800r / min, generating high-frequency vibration. This high-frequency vibration is transmitted to the ballast layer through the ballast shovel 7, loosening the compacted ballast and improving shaving efficiency. The bottom of the ballast slab 7 is welded to a ballast guide trough 9. The ballast guide trough 9 has an inclined structure and a ballast discharge port 10 at its end. The cleaned ballast is guided through the ballast guide trough 9 to the ballast discharge port 10 for discharge. The inclined design ensures that the ballast can flow smoothly to the designated location and avoid disorderly accumulation. The inner wall of the ballast guide trough 9 is coated with a wear-resistant coating to extend its service life and reduce maintenance costs.

[0030] The drive mechanism 11 provides power to the cleaning assembly 6 and includes a motor 12 and a transmission assembly 13. The motor 12 is bolted to one side of the frame 1, and its output shaft is connected to the transmission assembly 13 via a belt. The transmission assembly 13 includes a drive wheel 14 and a driven wheel 15. The drive wheel 14 is connected to the output shaft of the motor 12 via a multi-ribbed belt, which improves transmission efficiency and reduces operating noise. The driven wheel 15 is linked to the eccentric shaft of the vibrator 8 via a chain 16. A protective cover 17 is provided on the outside of the chain 16 to prevent the chain 16 from slipping off or becoming entangled with foreign objects during high-speed operation, ensuring the safety of the transmission process. Through the power transmission of the transmission assembly 13, the eccentric shaft of the vibrator 8 continues to rotate, thereby driving the ballast plate 7 to generate high-frequency vibration.

[0031] A control box 18 is mounted on the top of the frame 1. The control box 18 integrates a controller and a power module. The controller is electrically connected to the motor 12 and the vibrator 8 via cables to automate the screening operation. An operation panel 19 is mounted on the surface of the control box 18. The operation panel 19 includes a start button, a stop button, and a speed control knob. The start button is used to turn on the device, the stop button is used for emergency shutdown, and the speed control knob is used to adjust the speed of the motor 12, thereby controlling the vibration frequency of the vibrator 8. Through the operation panel 19, operators can easily control the device, reducing manual intervention and simplifying operation.

[0032] Auxiliary support rods 20 are symmetrically arranged on both sides of the frame 1. The auxiliary support rods 20 are connected to the frame 1 via pins, and adjustable feet 21 are provided at their bottom ends. The adjustable feet 21 are connected to the auxiliary support rods 20 via threaded engagement, and their bottom ends are equipped with anti-slip pads to enhance the stability of the device under different terrain conditions. During operation, the operator can adjust the height of the adjustable feet 21 according to the terrain conditions to keep the device level, further improving operational safety.

[0033] The specific operation process of this device is as follows: First, the device is moved to the railway slope cleaning and screening operation area. The height of the angle adjustment plate 5 is adjusted by the lifting rod 4 in the adjustment mechanism 3 to adapt the working posture of the cleaning component 6 to the slope angle. Then, the position of the angle adjustment plate 5 is fixed by the locking bolts, and the adjustable feet 21 on the auxiliary support rod 20 are adjusted to ensure that the device remains stable during operation. Next, the device is started by the operation panel 19 on the control box 18. The motor 12 starts to run, driving the drive wheel 14 in the transmission component 13 to rotate through the belt. The drive wheel 14 transmits power to the driven wheel 15 through the chain 16. The driven wheel 15 then transmits power to the eccentric shaft of the vibrator 8, causing the vibrator 8 to generate high-frequency vibration. The vibration of the vibrator 8 is transmitted to the ballast layer through the ballast scraper 7, loosening the hardened ballast. The loosened ballast is scooped up by the ballast scraper 7 and guided to the ballast discharge port 10 through the ballast guide trough 9, completing the cleaning and screening operation. Throughout the process, the operator can adjust the speed of the motor 12 using the speed control knob, thereby controlling the vibration frequency of the vibrator 8 to adapt to ballast of different hardness.

[0034] Through the above-mentioned structural design and operating principle, this device achieves efficient screening operations in railway slope areas, solving the problems of lack of professional design, low efficiency, and difficulty in adapting to complex terrain in existing technologies.

[0035] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the implementation principle and operation process of this device is provided in conjunction with a specific application scenario.

[0036] In railway slope cleaning operations, the device is first moved to the target cleaning area using the wheels 2. The operator adjusts the height of the lifting rod 4 in the adjusting mechanism 3 by rotating it according to the actual angle of the slope, thereby moving the angle adjusting plate 5 up and down to the appropriate position. The angle adjusting plate 5 is connected to the cleaning assembly 6 via a hinge. After the height of the lifting rod 4 is adjusted, the operator manually swings the angle adjusting plate 5 to adapt to changes in the slope's inclination angle. Then, the locking bolts are used to fix the position of the angle adjusting plate 5, ensuring the working posture of the cleaning assembly 6 is stable and in close contact with the slope surface. During this process, the serrated edge of the ballast shovel 7 can effectively cut into the ballast deposit layer. Its design parameters of 10mm to 15mm tooth spacing and 5mm to 8mm tooth depth ensure both cutting strength and avoidance of wear problems caused by improper tooth spacing or depth.

[0037] After adjusting the angle, the operator further adjusts the adjustable feet 21 on the auxiliary support rod 20. By rotating the adjustable feet 21, the anti-slip pads at their bottom are made to make close contact with the ground, ensuring that the entire device remains level during operation and enhancing stability. This design is particularly suitable for screening operations in complex terrain conditions, effectively preventing the device from tilting or shifting, thereby improving operational safety.

[0038] Next, the device is started via the operation panel 19 on the control box 18. After pressing the start button, the motor 12 starts running, and its output shaft drives the drive wheel 14 in the transmission assembly 13 to rotate via a multi-wedge belt. The drive wheel 14 transmits power to the driven wheel 15 via the chain 16, and the driven wheel 15 then transmits power to the eccentric shaft of the vibrator 8, causing the eccentric shaft to rotate at a high speed in the range of 1200 r / min to 1800 r / min. The eccentric shaft inside the vibrator 8 generates high-frequency vibration, which is transmitted to the ballast layer on the slope through the ballast shovel plate 7, loosening the compacted ballast. Because the ballast shovel plate 7 adopts an arc-shaped structure design, its serrated edge at the front end can penetrate deep into the ballast accumulation layer, which, combined with the high-frequency vibration effect, significantly improves the screening efficiency.

[0039] The loosened ballast is scooped up by the ballast shovel 7 and guided through the ballast guide trough 9 to the ballast discharge port 10 for discharge. The inclined design of the ballast guide trough 9 ensures that the ballast flows smoothly to the designated position under gravity, while the wear-resistant coating on the inner wall extends the service life of the ballast guide trough 9 and reduces maintenance costs. At the same time, the protective cover 17 covers the outside of the chain 16 to prevent the chain from derailing or becoming entangled with foreign objects during high-speed operation, ensuring the safety of the transmission process.

[0040] Throughout the screening process, the operator can adjust the speed of motor 12 using the speed control knob, thereby changing the vibration frequency of vibrator 8. When dealing with harder ballast, the speed of motor 12 can be appropriately increased to enhance the vibration intensity of vibrator 8 and achieve a better loosening effect; while when handling looser ballast, the vibration frequency can be reduced to decrease energy consumption. This flexible adjustment method allows the device to adapt to ballast of different hardness, further improving the adaptability and efficiency of the screening operation.
