Description

Technical Field

[0001] The present application relates to the field of ice and snow removal devices, and in particular to a turnout ice and snow removal device and method, and a turnout ice and snow removal vehicle. Background Art

[0002] Railway station turnouts are an important part of station transportation equipment. Railway transportation has very strict requirements on the technical status of turnouts. When the tip of the switch rail has a gap of more than 4mm with the basic track, the entry and opening signals cannot be locked. In winter snowy weather in cold areas, if the railway turnouts are not cleared of snow in time, snow or ice will accumulate in the turnouts, resulting in the tip of the switch rail and the basic track cannot be reliably and closely attached, which directly affects the normal operation of the station's train reception and dispatching operations and shunting operations, and in serious cases, may cause railway transportation interruption.

[0003] The main methods of snow and ice removal adopted by the existing technology are: 1. Manual snow removal, which requires a large amount of manpower, has low snow removal efficiency, poor effect and poor safety. 2. Electric heating snow removal, which requires a significant increase in electricity capacity, is prone to ice when the heating time is insufficient, and the heating strips are prone to fall off, affecting the close fit of the turnouts. The later maintenance costs such as replacing the heating strips are high, and the operating costs are high. 3. Wind snow removal requires the transformation of the station, and the project investment is large. 4. Snow removal with snow-melting agents will cause corrosion to the tracks, affect the performance of the track circuit, and is not conducive to environmental protection. Insufficient use of snow-melting agents will easily cause ice, which will in turn affect the turnout conversion, and the snow removal efficiency is low and the safety is poor.

A plurality of air nozzles are arranged at intervals along the length direction of the wind knife, and the diameter of the air nozzles is small to increase the flow rate of hot air and enhance the effect of snow and ice removal. Among them, the wind knives of the first air supply structure 21 and the second air supply structure 22 are respectively installed on the corresponding wind knife mounting seats 3414.

[0128] The present application also has a power supply system to provide power to the devices that need electricity, such as the blower 41, the heater 42, the lifting motor 322, the traverse motor 314, the rotating motor and the swing motor. The power supply system can be the power supply of the turnout deicing vehicle 2 of the present application, or it can be an external power supply.

[0130] The above is a detailed description of several exemplary embodiments of the turnout deicing and snow removal device 1 proposed in the present application. The turnout deicing and snow removal method proposed in the present application will be described in detail below.

[0131] Combined with Figure 1 , Figure 2 and Figures 14 to 17 The turnout deicing method proposed in the present application adopts the turnout deicing device 1 of the present application, including:

[0132] Step S1: Control the driving device 30 to drive the air supply device 20 to reach the area between adjacent tracks of the turnout 3;

[0133] Step S2: Control the hot air system 40 to deliver hot air to the air supply device 20 to remove ice and snow;

[0134] Fig.14 The above steps S1 and S2 are shown.

[0135] Step S3: Control the driving device 30 to drive the air supply device 20 to approach the upper surface of the track of the turnout 3, and the hot air system 40 delivers hot air to the air supply device 20 to remove ice and snow on the upper surface of the track; Fig.15 The above step S3 is shown.

[0136] Step S4: Control the driving device 30 to drive the air supply device 20 to approach the track side of the turnout 3, and the hot air system 40 delivers hot air to the air supply device 20 to remove ice and snow on the track side; Fig.16 The above step S4 is shown.

[0137] Step S5: Control the driving device 30 to drive the air supply device 20 to reach the track outer area of ​​the turnout 3, and the hot air system 40 delivers hot air to the air supply device 20 to remove ice and snow. Fig.17The above step S5 is shown.

[0138] See also Figures 14 to 17 In the turnout snow and ice removal method of the present application, after the turnout snow and ice removal vehicle 2 moves onto the turnout track, the air supply device 20 is first horizontally moved to an appropriate position by the transverse movement device 31, and then the rotating device 33 rotates the air supply device 20 to the area between the tracks of the turnout 3. After the lifting device 32 lowers the air supply device 20 to a position close to the ice and snow, the hot air system 40 supplies hot air to the air supply device 20 for snow and ice removal.

[0139] When the ice and snow in the area between the tracks of the turnout 3 are removed, the lifting device 32 lifts the air supply device 20 upward, and the transverse movement device 31 and the rotating device 33 horizontally move and rotate the air supply device 20 so that the air supply device 20 is aligned with the track. The lifting device 32 drives the air supply device 20 to descend to a position close to the upper surface of the track, and the air nozzle of the air supply device 20 is aligned with the upper surface of the guide rail 311. The hot air system 40 supplies hot air to the air supply device 20 to remove ice and snow.

[0140] Then, the driving device 30 drives the air supply device 20 so that the air nozzle of the air supply device 20 is aimed at the side of the track, and the hot air system 40 delivers hot air to the air supply device 20 to remove ice and snow. Finally, the driving device 30 drives the air supply device 20 so that the air supply device 20 reaches the outer area of ​​the track of the turnout, and the hot air system 40 delivers hot air to the air supply device 20 to remove ice and snow.

[0141] It can be seen from the above turnout deicing method that the turnout deicing device 1 of the present application can remove the ice and snow on the track surface and the track side of the turnout 3, as well as the ice and snow between the adjacent tracks of the turnout 3 and the track outside at one time. There is no need for multiple deicing devices or multiple deicing operations. The operation is simple, the deicing efficiency is high, and energy saving and efficiency improvement are achieved.

[0142] In summary, the turnout deicing and snow removal device proposed in the present application includes a mounting frame, an air supply device, a driving device and a hot air system. Among them, the air supply device, the driving device and the hot air system are all installed on the mounting frame. The driving device can drive the air supply device to lift up and down, move horizontally and rotate at any angle in the horizontal plane. The driving device can also drive the air supply device to swing with its own length direction as the axis. The hot air system delivers hot air to the air supply device, and the air supply device delivers hot air. Driven by the driving device, the air supply device can not only remove ice and snow on the upper surface and side of the track of the turnout, but also remove ice and snow between adjacent tracks of the turnout and on the outside of the track. The turnout deicing and snow removal device of the present application can be driven by the driving device to lift, move horizontally, rotate and swing, etc., to remove ice and snow from all parts of the turnout in all directions. It does not use snow melting agents, but adopts hot air heating. It does not need to modify the station. It has high snow removal efficiency and high safety. The cost of snow removal is low and the effect of deicing and snow removal is good.

[0143] The turnout de-icing and snow removal vehicle provided by the present application has only one turnout de-icing and snow removal device at the rear of the vehicle, which can remove the ice and snow on the upper surface and side of the turnout track, as well as the ice and snow between adjacent tracks and outside the track at one time. There is no need for multiple de-icing and snow removal devices, nor is there a need for multiple de-icing and snow removal operations. The hot air method is used to remove ice and snow, which is highly efficient, energy-saving and environmentally friendly.
