Description

Technical Field

[0001] This application relates to the field of railway technology, and more specifically, to snow removal devices for railway turnouts. Background Technology

[0002] Railway switches are an important component of railway transportation, and their safety and smooth operation directly affect the efficiency and safety of railway transport. In winter, snow accumulation and icing are among the main factors affecting the normal operation of railway switches; therefore, the research and application of snow removal technology for railway switches has significant practical implications. Currently, railway switch snow removal technologies mainly include two categories: mechanical snow removal and snow melting.

[0003] In related technologies, to achieve automated snow removal from railway turnouts, for example, patent CN216586360U provides an airflow-increased railway turnout snow removal device. This device uses airflow booster nozzles fixed to the railway main rail via a fixed bracket made of elastic material. Three to ten airflow booster nozzles are installed depending on the length of the railway turnout, with a distance of 550mm between every two nozzles. When it snows in winter, a snowfall sensor transmits the snowfall signal to a central controller, which then drives the system to... The signal is transmitted to the high-pressure blower, which starts after a 30-second delay. The high-pressure airflow output by the blower flows out along the exhaust duct at a certain speed. Multiple airflow booster nozzles on the outer surface of the exhaust duct, with the inner diameter of the outlet of each nozzle decreasing in stages, are used to create an air curtain from front to back, blocking the falling snow from entering the switch and ensuring that there is no snow accumulation between the switch rail and the main rail. This type of railway switch snow removal device has good snow removal effect, high safety, and requires no personnel operation, thus improving the efficiency of snow removal work.

[0004] While the existing technical solutions mentioned above can achieve the effect of automatically blowing air through the air pressure nozzles to form an air curtain and block the falling snow outside the turnout during winter snowfall by installing three to ten air pressure nozzles according to different railway turnout lengths, the air pressure nozzles are fixedly installed to the railway main rail by fixed brackets. Due to the dynamic load and vibration generated when the train passes over the railway main rail, coupled with the rain and snow in winter, the externally installed fixed brackets are prone to damage, thus losing support for the air pressure nozzles, resulting in unstable snow removal capacity.

[0005] In view of this, we propose a snow removal device for railway turnouts. Utility Model Content

[0006] The purpose of this application is to provide a snow removal device for railway turnouts, which can effectively solve the problem in the prior art where the airflow booster nozzle is fixedly installed to the railway main rail by a fixed bracket. However, due to the dynamic load and vibration generated when the train passes over the railway main rail, coupled with the rain and snow in winter, the externally installed fixed bracket is easily damaged, thus losing support for the airflow booster nozzle and resulting in unstable snow removal capacity.

[0007] This application provides a snow removal device for railway turnouts, including:

[0008] The base plate has a linear mechanism at its top;

[0009] The skateboard is slidably mounted on top of the base plate by the linear mechanism.

[0010] An adjusting plate is movably mounted on one side of the sliding plate; in the working state, the adjusting plate is positioned on the side closest to the railway main rail.

[0011] Several airflow boosting nozzles are arranged in a row, and all of the airflow boosting nozzles are located on the outside of the adjusting plate; in the working state, the output end of the airflow boosting nozzles faces into the turnout gap of the railway main rail.

[0012] As an optional solution to the technical solution of this application, a top plate is fixedly provided on the top of the skateboard, and a receiving box and a control box are provided between the skateboard and the top plate. A snow volume sensor is fixedly provided on the outside of the control box, and the snow volume sensor is electrically connected to the control box.

[0013] A fan is fixedly installed on the top of the top plate to deliver airflow into the airflow booster nozzle.

[0014] As an optional solution to the technical solution of this application, a motor is fixedly installed inside the housing box as the power source of the fan; a flexible tube is fixedly installed at the output end of the fan, and an air duct is fixedly installed at the other end of the flexible tube; airflow boosting nozzles are evenly arranged on the outside of the air duct.

[0015] The air duct is fixedly installed on the outside of the regulating plate, and the motor is electrically connected to the control box.

[0016] As an optional solution to the technical solution of this application, a slide rod is slidably provided on the inner side of the adjusting plate, the slide rod is fixedly provided on the outer side of the support plate, and a first adjusting screw is threadedly connected to the inner side of the support plate, one end of the first adjusting screw being rotatably connected to the adjusting plate.

[0018] As an optional solution to the technical solution of this application, a horizontal groove is provided on the top of the base plate, and a first slider is fixedly provided on the bottom of the slide plate corresponding to the horizontal groove, and the first slider is slidably disposed inside the horizontal groove.

[0019] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0020] This application utilizes an adjusting plate to support the arranged airflow booster nozzles, allowing the nozzles to be detached from direct installation on the railway main rail. Driven by a linear mechanism, the nozzles can move away from or closer to the railway main rail. This solves the problem that when airflow booster nozzles are fixedly installed on the railway main rail using a fixed bracket, the dynamic loads and vibrations generated when trains pass over the railway main rail, coupled with winter rain and snow, can easily damage the externally installed fixed brackets, leading to a loss of support for the airflow booster nozzles and unstable snow removal capabilities. This application enables the airflow booster nozzles to be moved away from the railway main rail after automatic snow removal, preventing damage from the dynamic loads and vibrations generated when trains pass over the railway main rail, thus ensuring the stability of snow removal capabilities.

[0021] This application prevents the airflow booster nozzle from being damaged by vibrations from the railway main rail by installing it separately from the railway main rail, thereby reducing the maintenance workload of the airflow booster nozzle and improving the stability of snow removal capabilities.

[0022] This application supports the airflow booster nozzle by setting an adjustment plate. When installing the airflow booster nozzle, the position of the adjustment plate can be adjusted to align the airflow booster nozzle with the gap of the railway main rail switch, so as to ensure that the subsequent adjustment plate can be driven by the sliding plate to make the airflow booster nozzle face the gap of the railway switch for automatic snow removal.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] Reference Figure 1 , Figure 3 and Figure 4 This application discloses a snow removal device for railway turnouts, including a base plate 1 fixedly installed on one side of the railway main rail. A linear mechanism 11 is fixedly installed on the top of the base plate 1, and a sliding plate 2 is slidably installed on the top of the base plate 1. The sliding plate 2 slides under the drive of the linear mechanism 11. An adjusting plate 3 is movably installed on the side of the sliding plate 2 close to the railway main rail. An airflow boosting nozzle 4 is installed on the outside of the adjusting plate 3 corresponding to the turnout gap of the railway main rail. Several airflow boosting nozzles 4 are arranged in a row.

[0034] When snow removal is performed, the linear mechanism 11 drives the slide plate 2 to slide on top of the base plate 1. This causes the slide plate 2 to move the airflow booster nozzles 4 arranged on the outer side of the adjusting plate 3 closer to the gap in the railway main rail. Then, airflow is blown into the gap through the airflow booster nozzles 4, forming an air curtain to prevent snow from falling into the gap, thus achieving automatic snow removal on the gap. When a train passes through the gap, the linear mechanism 11 retracts the slide plate 2 in advance, causing the slide plate 2 to move the airflow booster nozzles 4 on the outer side of the adjusting plate 3 away from the railway main rail. This prevents the vibration load generated when the train passes through the track from damaging the airflow booster nozzles 4, ensuring the stability of the snow removal capacity of the airflow booster nozzles 4. During the sliding process, the slide plate 2 achieves stable sliding by cooperating with the first slider 25 at the bottom and the horizontal sliding groove 12 at the top of the base plate 1.

[0035] In actual operation, the linear mechanism 11 can be selected from power components with linear output function, such as electric push rods, hydraulic push rods, or linear guides, which can drive the slide plate 2 to move. The operator can make a flexible selection according to the working conditions.

[0036] Reference Figure 1 and Figure 2 A top plate 21 is fixedly installed on the top of the slide plate 2. A housing box 22 and a control box 23 are arranged between the slide plate 2 and the top plate 21. A snow volume sensor 24 is fixedly installed on the outside of the control box 23. The snow volume sensor 24 is electrically connected to the control box 23. A fan 43 is fixedly installed on the top of the top plate 21 for supplying airflow to the airflow booster nozzle 4.

[0037] Specifically, when it snows in winter, the snow volume sensor 24 on the outside of the control box 23 detects the snowfall on the railway. Based on the signal fed back by the snow volume sensor 24, the control box 23 promptly controls the airflow booster nozzle 4 to discharge airflow to form an air curtain to clear the snowflakes; specifically, refer to Figure 1 and Figure 2 The housing 22 is equipped with a motor 44, which serves as the power source for the fan 43. A flexible tube 42 is fixedly installed at the output end of the fan 43, and an air duct 41 is fixedly installed at the other end of the flexible tube 42. Airflow boosting nozzles 4 are evenly arranged on the outside of the air duct 41. The air duct 41 is fixedly installed on the outside of the regulating plate 3, and the motor 44 is electrically connected to the control box 23.

[0038] When the control box 23 receives the snowfall signal from the snowfall sensor 24, it starts the fan 43 on the top of the top plate 21 by controlling the motor 44 inside the container 22. The fan 43 then inputs a stable airflow into the air duct 41 through the flexible pipe 42. As the airflow passes through the airflow boosting nozzles 4, the inner diameter of the output end of the airflow boosting nozzles 4 gradually decreases, thereby boosting the airflow. This causes the airflow boosting nozzles 4 to blow airflow out of the gaps in the turnout to form an air curtain, which then automatically removes snow from the railway turnout.

[0039] Reference Figure 1 and Figure 3 A sliding rod 31 is slidably provided on the inner side of the adjusting plate 3. The sliding rod 31 is fixedly provided on the outer side of the support plate 32. A first adjusting screw 33 is threadedly connected to the inner side of the support plate 32. One end of the first adjusting screw 33 is rotatably connected to the adjusting plate 3.

[0040] After the base plate 1 is fixedly installed on one side of the railway main rail, the distance between the airflow boosting nozzle 4 and the turnout gap is adjusted by controlling the linear mechanism 11 to push the slide plate 2 to slide a certain distance. Then, the horizontal distance between the output end of the airflow boosting nozzle 4 and the turnout gap is precisely adjusted by rotating the first adjusting screw 33, so as to ensure that the linear mechanism 11 can drive the slide plate 2 to slide a certain distance and thus enable the airflow boosting nozzle 4 to cooperate with the turnout gap.

[0041] Reference Figure 1 and Figure 3 A second slider 34 is fixedly installed on the outer side of the support plate 32. The second slider 34 is slidably installed on the inner side of the vertical slide groove 26. The vertical slide groove 26 is installed between the slide plate 2 and the top plate 21. A second adjusting screw 35 is rotatably installed on the top of the support plate 32. The second adjusting screw 35 is threadedly connected to the inner side of the top plate 21.

[0042] During the process of aligning the airflow booster nozzle 4 with the branch gap, the support plate 32 can be driven to slide vertically along the vertical slide groove 26 by rotating the second adjusting screw 35 on the inner side of the top plate 21, thereby adjusting the height of the output end of the airflow booster nozzle 4 so that the airflow booster nozzle 4 can be effectively aligned with the branch gap.

[0043] In summary, when using the railway turnout snow removal device disclosed in this application embodiment, the base plate 1 is first fixedly installed on one side of the railway main rail. The distance between the airflow boosting nozzle 4 and the turnout gap is adjusted by controlling the linear mechanism 11 to push the sliding plate 2 to slide a certain distance. Then, the horizontal distance between the output end of the airflow boosting nozzle 4 and the turnout gap is precisely adjusted by rotating the first adjusting screw 33. Furthermore, the support plate 32 can be driven to slide vertically along the vertical slide groove 26 by rotating the second adjusting screw 35 on the inner side of the top plate 21, thereby adjusting the height of the output end of the airflow boosting nozzle 4 so that the airflow boosting nozzle 4 can be effectively aligned with the turnout gap.

[0044] When it snows in winter, the snowfall sensor 24 on the outside of the control box 23 detects the snowfall on the railway. When the control box 23 receives the snowfall signal from the snowfall sensor 24, it controls the motor 44 inside the housing 22 to start the fan 43 on the top of the top plate 21. The fan 43 inputs a stable airflow into the air duct 41 through the flexible pipe 42. When the airflow passes through the airflow boosting nozzles 4, the inner diameter of the output end of the airflow boosting nozzles 4 gradually decreases, thereby boosting the airflow. This causes the airflow boosting nozzles 4 to blow airflow out of the gaps in the turnout to form an air curtain, which then automatically removes snow from the railway turnout.

[0045] When the train passes through the switch, the linear mechanism 11 retracts the slide plate 2 in advance, so that the slide plate 2 drives the airflow booster nozzle 4 on the outside of the adjusting plate 3 away from the railway main rail, so as to prevent the vibration load generated when the train passes through the track from damaging the airflow booster nozzle 4, and to ensure the stability of the snow removal capacity of the airflow booster nozzle 4.
