Description

Technical Field

[0001] This utility model relates to the field of monorail technology, and in particular to a snow blowing device for monorail vehicles. Background Technology

[0002] Monorail rubber-tired vehicles are used in urban rail transit and are located on elevated lines. In winter, after snowfall, the track surface is covered with ice and snow, which reduces the friction of the rubber tires and makes the vehicles prone to slipping, affecting vehicle operation.

[0003] Current methods for snow removal on monorails mostly rely on roller brushes, which are not very thorough. For example, Chinese patent CN115522503A discloses a fully automatic snow removal device for straddle-type monorails, which includes a mounting beam and a snow removal mechanism. The mounting beam is used to install on the front of the straddle-type monorail vehicle. The snow removal mechanism is used to clear snow from the upper surface of the straddle-type monorail. The snow removal mechanism includes a mounting frame, a roller brush, and a drive structure for driving the roller brush to rotate. Both the roller brush and the drive structure are mounted on the mounting frame, which is liftable and mounted on the mounting beam. Utility Model Content

[0004] In view of the shortcomings of existing technology, this utility model provides a snow blowing device for monorail vehicles to achieve the purpose of thorough snow removal.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] The snow blowing device for the monorail vehicle includes a mounting bracket, a device housing, a blower, and an air outlet nozzle;

[0007] The mounting bracket is used for the mechanical connection between the snow blowing device and the monorail vehicle body.

[0008] The device housing is used to support the device components, and the device housing is connected to the mounting bracket;

[0009] The fan is used to generate airflow and is housed inside the device housing.

[0010] The air outlet nozzle is used to blow away the snow on the running surface of the track beam. The air outlet nozzle is located on the side of the device box and is connected to the fan.

[0011] Further:

[0012] The mounting brackets are arranged in a row and are fixed to the top of the device housing.

[0013] The fan is a centrifugal fan.

[0014] The air outlet nozzle has a pointed tip structure.

[0015] The device housing is equipped with a frequency converter for controlling the start and stop of the fan.

[0016] The device housing is equipped with a set of air inlets.

[0017] A heating structure is provided between the fan and the air outlet nozzle.

[0018] An electrical connector is provided on the outside of the device housing.

[0019] Compared with the prior art, this utility model has the following advantages:

[0020] The snow removal device for this monorail vehicle is designed so that the snow removal device is installed on the lower part of the vehicle body via a bracket. The high-speed airflow blows the snow onto the running surface of the monorail vehicle track beam, which can blow away the snow on the running surface of the track beam, thus removing the snow thoroughly. This can improve the vehicle's operational capability in snowy weather, enhance the product's competitiveness, and ensure the operational capacity of rail transit. Attached Figure Description

[0026] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0027] like Figure 1 and Figure 2 As shown, the snow blowing device for the monorail vehicle includes a mounting bracket 1, a device housing 4, a blower 2, and an air outlet nozzle 3. The mounting bracket 1 is used for the mechanical connection between the snow blowing device and the monorail vehicle body. The device housing is used to support the device components, and the device housing and the mounting bracket are connected. The blower 2 is used to generate airflow, and the blower is located inside the device housing. The air outlet nozzle 3 is used to blow away the snow accumulated on the running surface of the track beam 7, and the air outlet nozzle is located on the side of the device housing and connected to the blower.

[0028] This utility model relates to a snow blowing device structure for monorail vehicles. The snow blowing device is installed on the lower part of the vehicle body via a bracket. A high-speed airflow blows onto the running surface of the monorail vehicle's track beam, which can blow away the snow on the running surface of the track beam, thus thoroughly removing the snow. This can improve the vehicle's operational capability in snowy weather, enhance the product's competitiveness, and ensure the operational capacity of rail transit.

[0029] Mounting bracket 1 is a set arranged side by side. The mounting bracket is fixed to the top of the device box. The entire device is suspended and has a compact structure.

[0030] Fan 2 is a high-speed centrifugal fan with a pointed nozzle structure to increase the air velocity and thus improve the cleaning effect.

[0031] Furthermore, a heating structure is provided between the fan and the air outlet nozzle. Specifically, the fan and the air outlet nozzle are connected by an air duct, and the heating structure is a heater integrated within the air duct to heat the airflow, thereby improving the snow removal effect.

[0032] The device housing 4 is equipped with a set of air inlets, which can reduce the weight of the device; the device housing is equipped with a frequency converter 5 for fan start and stop control; the device housing is equipped with an electrical connector 6 on the outside of the device housing. All components are integrated to form an overall modular structure, which is easy to install.

[0033] Existing monorail vehicles cannot cope with the operational scenario of icy track surfaces after snowfall. With the addition of snow blowing devices, snow can be cleared from the track surface along with the operating vehicles during snowfall, preventing the track surface from freezing and the vehicles from slipping.

[0034] The preferred embodiment of this utility model is as follows:

[0035] The snow blowing device for monorail vehicles specifically includes the following components:

[0036] Equipment hanging and fixing bracket: Purpose: Used for mechanical connection between snow blowing device and vehicle body.

[0037] High-pressure blower: Within the existing installation dimensions of the monorail base equipment, a large-size, high-volume high-pressure centrifugal blower is selected. Application: The centrifugal blower delivers high total pressure airflow, providing a high-speed airflow to blow snow off the track surface.

[0038] Air outlet nozzle: Purpose: Connected to the air outlet of the fan, the nozzle gradually narrows to increase the airflow speed.

[0039] Device enclosure: Purpose: Used to support components such as high-pressure blowers and frequency converter connectors.

[0040] Frequency converter: Application: Used for starting and stopping high-pressure blowers. High-pressure blowers must be started by frequency converters, otherwise the excessive inrush current will affect the coil windings.

[0041] Electrical connectors: Application: Electrical interfaces between the power supply and control lines of the device and the vehicle.

[0042] The device is installed at the bottom of the monorail vehicle, with the entire unit housed within a casing and mechanically fixed to the vehicle body via a hanging bracket. Power and control from the vehicle are transmitted to the device via an electrical connector. Upon receiving power and start / stop requests, the device activates a high-pressure blower via a frequency converter. The blower draws in outside air, pressurizes it, and ejects it from the outlet nozzle, achieving an airflow speed exceeding 50 m / s. This high-speed airflow is directed towards the running surface of the monorail vehicle's track beams, blowing away snow and thus achieving the purpose of snow removal.

[0043] like Figure 2 This is a schematic diagram of the snow blowing device installed on a rubber-tired monorail train. It can be seen that the high-speed airflow blown by the high-pressure fan of the snow blowing device blows the snow on the track surface at the center of the vehicle, which can blow the snow on the track surface off the track. This prevents the snow from accumulating, reduces the risk of subsequent icing, and ensures the normal operation of the vehicle in snowy weather.

[0044] The addition of this snow blowing device to monorail vehicles will improve their operational capabilities in snowy weather, enhance product competitiveness, and ensure the operational capacity of rail transit.

[0045] The above description is only a preferred embodiment of the present utility model. The above technical features can be arbitrarily combined to form multiple embodiments of the present utility model.

[0046] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the concept and technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
