[0001] The utility model belongs to the technical field of road-rail dual-purpose vehicle rubber tire drying devices, and in particular relates to an air blowing device used for drying road-rail dual-purpose vehicle rubber tires. Background Art
[0002] A road-rail vehicle is a vehicle that can travel on both roads and rails by its own power. Its main purpose is to tow railway trains or other engineering operations on railway lines. Its road travel function is mainly used for short-distance movement of the vehicle itself to switch to other railway lines for traction operations. Road-rail vehicles play an important role in the daily alignment of coal cars arriving at the port, but on rainy days, the rails and tires are slippery and slipping is very likely to occur. In severe cases, road-rail vehicles may derail and overturn. In order to avoid accidents on rainy days and normal use in rainy weather, road-rail vehicles in the prior art often use the method of blowing air into the track, but simply blowing air into the track is generally ineffective, and slipping will still occur when used on rainy days, posing a major safety hazard.

[0008] Preferably, the three-way connector connected to the main air pipe is a quick-plug connector.
[0009] Preferably, the distance between the tire blowing nozzle and the road-rail vehicle tire is 4-6 mm.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] On the basis of the four air nozzles of the track blowing nozzles on both sides of the body of the road-rail vehicle, four tire blowing nozzles perpendicular to the tires of the road-rail vehicle are added. In order to ensure the blowing effect, this device adopts a duckbill blowing nozzle with a row of air outlet holes set on the blowing surface. The diameter of the air outlet hole is 1.5mm.

[0020] See also Figure 1-Figure 4 As shown, the utility model provides the following technical solutions:
[0021] A blowing device for drying rubber tires of a road-rail vehicle comprises: an air compressor 2 installed on the road-rail vehicle and a blowing assembly connected to the air compressor 2, wherein the air compressor 2 is connected to a main air pipe, and the other end of the main air pipe is connected to a three-way joint 8 for gas, the three-way joint 8 connected to the main air pipe is a quick plug-in joint, and the other two ends of the three-way joint are connected to a first air pipe and a second air pipe, and the air pipe is a hose.
[0022] A group of blowing assemblies are provided on both sides of the body of the road-rail dual-purpose vehicle, and the blowing assemblies include a first group of blowing nozzles arranged on the outer sides of the two tires and a second group of blowing nozzles arranged between the two tires, and the first group of blowing nozzles and the second group of blowing nozzles are both installed and fixed through a base 9 on the wheel steel structure frame, and the base is provided with an upwardly inclined connecting plate, and the base is welded to the chassis of the road-rail dual-purpose vehicle through the connecting plate, and the base is provided with a support plate, and a groove 10 for placing a branch pipe is provided on the upper surface of the support plate, and fixing holes passing through the base are provided on both sides of the support plate and the duckbill type blowing nozzle placement position, and the fixing holes are used to fix the duckbill type blowing nozzle 12, and can be fixed with a cable tie or a fixing buckle.
[0023] The first group of blowing nozzles is provided with two track blowing nozzles 4 that blow air vertically toward the rails. The track blowing nozzles 4 are duckbill-type blowing nozzles 12. A row of multiple air outlet holes 11 are provided on the blowing surface of the track blowing nozzles. The diameter of the air outlet holes 11 is 1.5 mm. The air pressure can be increased more effectively by setting the row of air outlet holes 11 to 1.5 mm. When the air pressure is increased, the rain and snow sticking to the rails can be removed more effectively. The two track blowing nozzles are respectively arranged on the outside of the two tires 6. The other end of the first air pipe is connected to the track blowing nozzles 4 arranged on both sides of the vehicle body through branch pipes.
[0024] The second group of blowing nozzles is two tire blowing nozzles 7, and the blowing directions of the two tire blowing nozzles 7 are arranged perpendicular to the tires 6 of the road-rail dual-purpose vehicle. A row of multiple air outlets 11 are arranged on the blowing surface of the tire blowing nozzle 7, and the diameter of the air outlet 111 is 1.5 mm. The air pressure can be increased more effectively by setting the air outlets in a row to 1.5 mm. When the air pressure is increased, the rain and snow sticking to the tires can be more effectively removed. The other end of the second air pipe is connected to the tire blowing nozzles 7 arranged on both sides of the vehicle body through branch pipes. The distance between the tire blowing nozzle 7 and the tire 6 of the road-rail dual-purpose vehicle is 5 mm, which is the most preferred. Selecting a 5 mm setting can not only effectively remove the rain and snow on the tire, but also prevent the tire from rubbing against the tire blowing nozzle.

When the air compressor starts to run and the air filling operation begins, the gas is first transported to the three-way joint through the air pipe, and then transported to the first air pipe and the second air pipe through the other two ends of the three-way joint, and then transported to the track blowing nozzle and the tire blowing nozzle respectively through the branch pipes connected to the first air pipe and the second air pipe. The track blowing nozzle and the tire blowing nozzle are duckbill-type blowing nozzles. Since a row of multiple air outlet holes are provided on the blowing surface of the duckbill-type blowing nozzle, and the diameter of the air outlet holes is 1.5mm, the duckbill-type blowing nozzle can increase the air pressure to more effectively remove rain and snow on the tires and rails. The tire blowing nozzle is set perpendicular to the tire of the road-rail dual-purpose vehicle at a distance of 5mm, and the track blowing nozzle blows vertically toward the rails.
