Description

Technical Field

[0001] The utility model belongs to the technical field of rail transit, and particularly relates to a rail snow removal device. Background Technique

[0002] Northern China is located in the temperate zone, with a long freezing period and frequent snowfall and icing in winter. In recent years, there have also been frequent blizzards. Seasonal low temperatures and snowfall in some cold and severe cold regions have exacerbated the potential safety hazards in railway engineering construction and operation. Especially in Northeast and Northwest China, the snow drift formed by snow under the action of wind is likely to accumulate around railway infrastructure and even bury the tracks, resulting in the interruption of railway transportation. At present, the common practice is for railway operation departments to take targeted measures in advance according to the snowfall intensity forecast released by the meteorological department, such as reducing the driving speed or even suspending operation when the snowfall intensity is large. When encountering heavy snowfall and a long snowfall period, it will seriously affect the transportation efficiency and may even cause railway safety accidents;

[0003] When there is too much snow on the railway track, it is easy for the turnout to be snow-covered and unable to be switched flexibly, resulting in the abnormal operation of the train. Rail snow removal is an important link to ensure the smooth operation of railway traffic. At present, the methods of rail snow removal are as follows:

[0004] 1. Manual snow removal: Manually remove the snow and ice on the railway using tools such as shovels and brooms. This method is applicable to situations with less snow or in special locations.

[0005] 2. Mechanical snow removal: Use various mechanical equipment for snow removal operations, such as railway snow sweepers and railway snow plows. These devices can quickly remove large areas of snow and improve the snow removal efficiency.

[0006] 3. Chemical snow removal: Sprinkle chemical snow melting agents on the track to make the snow melt into water by reacting with the snow, or reduce the adhesion of ice through snow melting agents to accelerate the melting of snow.

[0007] 4. Combustion snow removal: Use a flame sprayer to heat and burn the ice and snow to make it melt quickly. This method is applicable to some severely ice and snow-covered areas.

[0008] Compared with the complexity of manual snow removal, chemical snow removal, and combustion snow removal, mechanical snow removal is currently a more applicable and flexible option. In recent years, the development of railway snow removal equipment has gradually matured. For example, the large snow removal vehicle of the GCX-1000 type, which integrates functions such as blowing, sweeping, and snow throwing and is used in combination with a snow pusher, can quickly and efficiently remove severe snow on the railway. However, due to its high cost, there are only about 5 units equipped in China at present.

[0009] According to patent queries and comparisons, most track snow and ice removal devices are only for snow and ice removal on two railway tracks or turnouts. Some are just single snow plows, some are just single snow brushes, and some are just single snow crushing and throwing machines. There are individual small track car-type integrated devices, but they are all limited to between two tracks or do not consider the requirements of the railway vehicle clearance. Those relatively close or similar to the present invention are as follows:

[0010] 1. Patent document (CN 220847341 U), proposed by China Railway Eryuan Engineering Group Co., Ltd., Wei Dehao, etc., for a snow removal vehicle for rack railways. The snow removal range is only limited to between two tracks and lacks a rail surface de-icing device.

[0011] 2. Patent document (CN 220079875 U), proposed by Hunan Shuangda Electromechanical Co., Ltd., Qing Lichun, etc., for a snow removal device and a snow removal assembly, a device that can be lifted up and down installed under the vehicle, without a snow throwing device, without a rail surface de-icing device, and the snow removal range is also only limited to between two tracks.

[0012] 3. Patent document (CN 103469758 A), proposed by Harbin University of Science and Technology, Jiang Jingang, etc., for a railway snow removal machine. The snow removal range is only limited to between two tracks, lacks a rail surface de-icing device, and requires a special connection mechanism to connect with the vehicle and cannot be quickly connected to multiple types of power cars.

[0013] 4. Patent document (CN 105648973 B), proposed by China Railway Corporation, Guo Guanzhu, etc., for a track snow removal vehicle. By designing a large snow removal vehicle with power, it is dedicated to a specific use, with a very high cost and lacks a rail surface de-icing device.

[0014] Large snow removal vehicles are very suitable for the situation where the entire ballast is covered by heavy snow. However, for the situation where only the rail surface of the ballast is covered by medium or light snow, it is too wasteful. Many railway administrations have chosen snow removal equipment that can be used on both highways and railways. However, in this case, generally the snow plow cannot reach below the rail surface, and the snow removal equipment that can be used on both highways and railways still has problems such as high cost, complex technology, inconvenient maintenance, and limited use. Utility Model Content

[0015] To solve the problem of rapid track snow removal, the present utility model provides a track snow removal device.

[0016] A track snow removal device of the present utility model includes a track car frame, a snow plow, a snow throwing fan, a snow throwing tube, a snow collecting auger, a hydraulic pump station, an electric control system, a snow sweeping roller brush, a rail surface de-icing device, traveling wheels, and a coupler. The entire track snow removal device uses the track car frame as a loading platform. Four traveling wheels are installed at the bottom of the track car frame and can run smoothly on the track. The track car frame is connected to the power car through a coupler, and the power car provides the driving power.

[0017] At the very front of the rail car frame, a snow plow is installed and connected. The snow plow is V-shaped; behind the snow plow, the snow throwing fan and the snow collecting auger are integrated. At the top of the snow throwing fan, a snow throwing tube that can rotate 180 degrees is connected; behind the snow collecting auger, a snow sweeping brush is installed. Between the snow sweeping brush and the rear axle traveling wheels, two rail surface de-icing devices are installed.

[0018] An electric control system is installed on the rail car frame. The electric control system draws power by connecting with a quick-connect plug from the power car; the electric control system is equipped with a remote control switch to supply power to the hydraulic pump station and control the start or stop of the hydraulic pump station; the hydraulic pump station is connected to the hydraulic motors installed on the snow throwing fan, the snow collecting auger, and the snow sweeping brush through hydraulic pipelines to provide hydraulic power for their rotation and operation.

[0019] Further, the coupler is the coupler head of the No. 17 coupler, which can perform quick coupling operations with power cars of different models.

[0020] Further, the traveling wheels are non-metallic anti-slip rubber-coated wheels, which can travel stably on the track and will not trigger the axle counter.

[0021] Further, the overall structure of the rail car frame does not exceed the vehicle gauge requirements of the "GB 146.1 Standard Gauge Railway Locomotive and Carriage Gauge". The inner distance between two wheels on the same axis meets the gauge requirements, and it can pass through the turnout smoothly.

[0022] Further, the total width of the snow plow is 2500 mm. The snow plow blade surface is formed by tangency of a slope section at an angle of 40 degrees to the horizontal and an arc section with a radius of 200 mm.

[0023] Further, the diameter of the snow sweeping brush is 800 mm. The brush filaments of the snow sweeping brush are made of nylon, and the distal end of the brush filaments can reach 200 mm below the rail surface.

[0024] Further, the snow throwing tube can be selected to rotate and face one side of the track ballast.

[0025] Further, the rail surface de-icing device is driven by a motor to rotate. A stainless steel wire disk brush is installed on the motor shaft. An ice-breaking tooth disk with teeth is designed in the middle of the disk brush. The rail surface de-icing device can adjust the contact force between the disk brush and the rail surface up and down.

[0026] Further, the hydraulic pump station is a system device integrating a motor, a hydraulic oil tank, a hydraulic pump, and a hydraulic valve.

[0027] The beneficial technical effects of the present utility model are:

[0028] (1) Reduce labor intensity. In view of the previous situation where snow removal operations were carried out manually or with large snow removal vehicles, the utility model uses a small vehicle that can flexibly run on the track as a loading platform, and sequentially arranges a snow plow, a snow throwing device, a snow sweeping brush and a rail surface deicing device at the front and rear of the small vehicle. When the track snow removal device runs on the track, the snow plow can push the relatively thick snow accumulated above the rail surface to both sides of the track, and then the brush sweeps and clears the snow on and below the rail surface and throws it forward. The snow throwing device accumulates the snow through the auger device and throws it to both sides of the track after the snow throwing fan. Finally, the rail surface deicing device can sweep and remove the snow or ice layer on the rail surface, completing the snow and ice removal operation for the entire roadbed. The whole operation process does not require much participation from the operator. The operator only needs to start or stop the operation remotely in the power vehicle, greatly improving the snow removal efficiency. At the same time, the working environment of the operator is greatly improved, and the labor intensity is reduced.

[0029] (2) Reduce capital costs. The track snow removal device adopts a snow removal mode design that integrates "pushing - shoveling - sweeping - throwing". It mainly considers that in light to moderate snow weather, the roadbed rail surface is covered with snow, which affects the normal operation of the train or brings risks to the operation, and quickly and conveniently disposes of the risks. At the same time, it also takes into account the situation where there is relatively thick snow in some local areas, so the functions of pushing and shoveling snow are added on the basis of snow sweeping. The whole track snow removal device is small, flexible, fully functional, easy to use and occupies less space. The specialization and low cost of the equipment reduce the idle waste of capital costs.

[0030] (3) Improve operation efficiency. In the traditional snow removal method, when the snow only covers below the rail surface, the commonly used simple snow plow is ineffective, while the fully functional large snow removal vehicle is a waste and cannot be equipped in all stations and sections. Once used, it will seem inadequate. The track snow removal device takes into account both cost and function considerations, is suitable for being equipped in multiple stations and sections, and can operate simultaneously in small areas and multiple regions in case of disaster risks, greatly improving the overall operation efficiency.

[0033] In the figure: 1 - track trolley frame, 2 - snow plow, 3 - snow throwing fan, 4 - snow throwing cylinder, 5 - snow collecting auger, 6 - hydraulic pump station, 7 - electric control system, 8 - snow sweeping brush, 9 - rail surface deicing device, 10 - walking wheel, 11 - coupler, 12 - track, 13 - power vehicle. Detailed Implementation Modes

[0034] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] The utility model is a track snow removal device as Figure 1 As shown, it includes a track trolley frame 1, a snow removal shovel 2, a snow throwing fan 3, a snow throwing barrel 4, a snow collecting auger 5, a hydraulic pump station 6, an electric control system 7, a snow sweeping roller brush 8, a rail surface deicing device 9, a running wheel 10 and a coupler 11. The entire track snow removal device uses the track trolley frame 1 as a bearing platform. Four running wheels 10 are installed at the bottom of the track trolley frame 1 so that it can run smoothly on the track 12. The track trolley frame 1 is connected to the power car 13 through the coupler 11, and the power car 13 provides driving power.

[0036] like Figure 2 As shown, a snow shovel 2 is installed and connected at the front of the track trolley frame 1. The snow shovel 2 is V-shaped and pushes the snow piled high on the roadbed to both sides of the roadbed. Behind the snow shovel 2 is a snow throwing fan 3 and a snow collecting auger 5. The snow collecting auger 5 rotates to twist the snow from both sides to the middle snow throwing fan 3. The snow throwing fan 3 throws the snow into the snow throwing cylinder 4 through the centrifugal force of rotation. The connection between the snow throwing cylinder 4 and the snow throwing fan 3 can rotate 180 degrees and can be fixed to one side of the roadbed. The centrifugal force generated by the snow throwing fan 3 on the snow and the wind pressure generated by the impeller of the snow throwing fan 3 throw the snow through the snow throwing cylinder 4 to a farther position. Behind the snow collecting auger 5 is a snow sweeping roller brush 8. The diameter of the snow sweeping roller brush 8 is 800mm. The brush wire of the snow sweeping roller brush 8 is made of nylon, which is moderately soft and hard. The far end of the brush wire can reach 200mm below the rail surface. The snow sweeping roller brush 8 can sweep the snow on the track and deposit it in front of the snow sweeping roller brush 8 by rotating forward, and the snow sweeping roller brush 8 can throw the accumulated snow forward to the snow collecting auger 5, and then throw it to both sides of the roadbed through the snow collecting auger 5, the snow throwing fan 3 and the snow throwing cylinder 4. Two rail surface deicing devices 9 are installed between the snow sweeping roller brush 8 and the rear axle running wheel 10. The rail surface deicing devices 9 are driven to rotate by a motor and use a wire brush to sweep the ice layer on the track 12. The rail surface deicing devices 9 can adjust the contact force between the brush and the rail surface up and down. Through the integrated matching of this set of mechanisms, the final snow removal function is achieved.

[0037] An electric control system 7 is installed on the rail trolley frame 1, and the electric control system 7 draws electricity from the power car 13 using a quick-connect plug; the electric control system 7 is equipped with a remote control switch to supply power to the hydraulic pump station 6 and control the start or stop of the hydraulic pump station 6; the hydraulic pump station 6 is connected to the hydraulic motors installed on the snow throwing blower 3, the snow collecting auger 5 and the snow sweeping roller brush 8 through hydraulic pipelines to provide them with hydraulic power for rotation.

[0038] The snow removal device for tracks of the present utility model is formed by integrating a snow removal mode of "pushing - shoveling - sweeping - throwing". A snow plow is installed in front of the snow removal device for tracks, which can push and shovel the relatively thick snow above the rail surface to both sides of the track. The rolling brush type snow sweeping method is adopted. The rolling brush can reach the area 200 mm below the rail surface. The rolling brush is made of flexible material and is applicable to intrusion operation. A snow throwing device is installed in front of the rolling brush. As the rolling brush rotates forward, the snow is thrown forward. Part of the snow falls into the snow throwing device and is thrown to both sides of the roadbed, and part of the snow falls back onto the roadbed in front of the rolling brush. As the snow removal device for tracks moves forward, the rolling brush continuously throws the snow in front towards the snow throwing device, and the snow is continuously thrown to both sides of the roadbed, achieving the purpose of snow removal. At the same time, an ice removal device for the rail surface is designed behind the rolling brush, which drives a wire brush disc through a high-speed rotating motor to sweep the ice layer on the rail surface.

[0039] The snow removal device for tracks of the present utility model can be externally connected to the 380V power supply on the power vehicle, or can be independently equipped with a small generator to provide power. A set of hydraulic pump stations is installed on the snow removal trolley for tracks. The snow sweeping rolling brush and the snow throwing device are driven by hydraulic motors.

[0040] The snow removal device for tracks of the present utility model is pushed and operated by connecting to a power rail vehicle. The operator conducts start / stop operation of the snow removal operation by remote control in the power vehicle cab.

[0041] Furthermore, the track trolley of the present utility model has the ability to run on the track, and the running requires connecting and pushing by a power vehicle. A coupler head of No. 17 car coupler is installed on the track trolley, which can achieve quick connection operation with power vehicles of different models. The 4 wheels on the track trolley can be non-metallic anti-slip rubber-coated wheels, which can run stably on the track and will not trigger the axle counter. When the snow removal device for tracks runs on the track, the overall steel structure is within the vehicle gauge requirements, without over-limit hard structures, and the driving is safe. The inner distance between the two coaxial wheels meets the gauge requirements and can pass through the turnout smoothly.

[0042] Furthermore, the snow plow in front of the snow removal device for tracks of the present utility model is V-shaped, which can push and shovel the relatively thick snow accumulated above the rail surface to both sides of the track. The total width of the snow plow is 2500 mm. The snow plow surface is formed by a slope section at an angle of 40 degrees with the horizontal and an arc section with a radius of 200 mm tangent to each other, which is beneficial to continuously pile and roll the snow towards the side front. Under the action of the overall V-shaped plow surface, the snow is continuously piled up on both sides.

[0043] Furthermore, a set of ice removal devices for the rail surface is installed at the front of the rear wheels on both sides of the track trolley of the present utility model. The ice removal device for the rail surface is driven by a motor and can adjust the contact force between the brush disc and the rail surface by lifting. The brush disc uses stainless steel wire brush filaments, and a tooth disc for ice breaking is designed in the middle of the brush disc, which is beneficial to break and remove the relatively high and thick ice layer on the rail surface. The wire brush disc is mainly aimed at thin ice layers about 1 mm thick.

[0044] Furthermore, the rotary brush and snow throwing device of the present utility model are both driven by hydraulic motors, and the hydraulic power is provided by a hydraulic pump station, and they are powered by the 380V power supply of an external power vehicle or a self - contained generator set. The start / stop operation of snow removal work is completed by remote control in the power vehicle cab.

[0045] Furthermore, the track snow removal trolley of the present utility model adopts a snow removal structure design that integrates "pushing - shoveling - sweeping - throwing". Through the track trolley method, multiple functions are integrated, realizing a small and comprehensive design. The track snow removal trolley adopts the connection method of the coupler of a track train, which can quickly achieve installation and connection and quickly respond to vehicle operation. The small - scale comprehensiveness of the track snow removal trolley reduces the procurement cost, is suitable for more stations and sections to be equipped, and can carry out simultaneous operations at multiple section points in case of snow disaster risks, quickly eliminate risks, and quickly resume traffic.
