Description

TECHNICAL FIELD

[0001] The utility model relates to the field of locomotive braking technology, especially a tractor inflation device based on train air brake. BACKGROUND

[0002] The loading platform is widely used in the steel smelting and coastal port logistics industries as an important facility for modern logistics and production, and is a key production hub for realizing the rapid delivery of bulk goods. During the loading platform operation, a tractor is usually provided to pull the train carriages for loading operation. The train carriage brake mainly relies on the compressed air brake. The working principle of the system is that when the air brake of all the carriages is in a full air state, the brake is released, and at this time the tractor can smoothly pull the train carriages for normal operation. However, in the actual operation process, due to the aging of the sealing components or the misalignment of the compressed air pipe connection of the train carriage air brake, the carriages may leak. Once a carriage leaks, the air brake of the entire train will not be able to maintain sufficient pressure, resulting in the entire train being in a locked brake state. In order to release this brake state, the operator must release the air one by one, which not only greatly increases the time and difficulty of production operation, but also seriously affects the production efficiency. SUMMARY

[0003] The utility model aims to provide a tractor inflation device based on a train air brake, which can solve the problem that the existing loading platform tractor cannot quickly release the locked brake state when a single or multiple carriages leak during the process of pulling the train carriages.

[0004] To solve the above problems, the utility model adopts the technical scheme of a tractor inflation device based on a train air brake, which includes an air compressor installed on the tractor, a first compressed air pipe, and a second compressed air pipe installed on each train carriage. The second compressed air pipe is in communication with the air inlet port of the train carriage air brake. One end of the first compressed air pipe is connected to the air outlet of the air compressor, and the other end is connected to a connecting flexible pipe. The two ends of the second compressed air pipe are respectively connected to the connecting flexible pipe. The connecting flexible pipes between the tractor and the train carriages or between two train carriages are connected through a handshake valve.

[0005] In the above technical scheme of the tractor inflation device based on a train air brake, the more specific technical scheme can be that a compressed air valve is installed on the first compressed air pipe.

[0006] In some possible embodiments, the compressed air valve has two.

[0007] In some possible embodiments, one end of the first compressed air pipe extends out of the tractor through the connecting flexible pipe, and the other end of the second compressed air pipe extends out of the corresponding train car.

[0008] In some possible embodiments, one of the compressed air valves is installed on the extended section of the first compressed air pipe, and the other compressed air valve is installed close to the air compressor.

[0009] In some possible embodiments, the connecting flexible pipe is a rubber hose.

[0010] With the above technical solutions, the present application has the following advantages over the prior art:

[0011] 1. By installing the air compressor and the first compressed air pipe on the tractor, and installing the second compressed air pipe on each train car, and connecting the compressed air pipes through the connecting flexible pipe and the hand valve, compressed air can be directly supplied to the air brake of the train car. When a train car leaks and causes the entire train to be in a locked braking state, the tractor can quickly supply compressed air to the leaking train car through the device to restore the pressure of the braking system, thereby quickly and effectively eliminating the locked braking state, avoiding the tedious operation of manually pulling the hook and releasing the air in the traditional method, saving manpower and reducing work intensity, significantly reducing the interruption time of the operation, and improving the overall work efficiency. The structure is simple, easy to install and maintain, easy to operate, and has high reliability.

[0012] 2. The compressed air valve installed on the first compressed air pipe can accurately control the flow of compressed air, avoid system instability caused by abnormal air pressure, and ensure the safety and reliability of the inflation process. The compressed air valve can quickly cut off the air supply in an emergency to prevent equipment damage or safety accidents, enhance system safety, and avoid waste of compressed air through adjustment, reduce energy consumption and operating costs.

[0013] 3. The double-valve design can achieve segmented control. The valve close to the air compressor is used to adjust the overall air supply pressure, and the valve on the extended section is convenient for on-site quick adjustment, improving the flexibility and accuracy of operation. At the same time, the double-valve design facilitates fault diagnosis and maintenance, reduces system downtime, and improves the reliability and practicality of the device.

[0014] 4. The end of the compressed air pipe extends to the outside of the tractor and the train car, facilitating the quick docking and dismounting of the connecting flexible pipe, simplifying the operation process, improving the operation efficiency, and reducing the operation difficulty.

[0017] The utility model will be made further detailed description in combination with the drawings embodiment:

[0018] Figure 1 As shown in a kind of tractor inflation device based on train air brake, the device is installed on tractor 2 and train car 4, tractor 2 is used to pull train car 4 to walk on track, and train car 4 is the carriage for transporting goods on train track, and car air brake 9 is installed on the bottom, and car air brake 9 is used as the brake assembly device of train car 4, and compressed air is conducted to the wheel shoe of train car 4 as power medium, to realize braking or unbraking.

[0019] The air inflation device of the tractor of the present embodiment mainly comprises an air compressor 1, a compressed air pipe, a connecting flexible pipe 7 and a handshake valve 8. The air compressor 1 is installed on the tractor 2 as a power device for providing compressed air, and can supplement air pressure for the air brake of the train car 4, so as to quickly release the braking state and significantly improve the work efficiency. The compressed air pipe comprises a first compressed air pipe 3 installed on the tractor 2 and a second compressed air pipe 10 installed on each train car 4. One end of the first compressed air pipe 3 is connected to the air outlet of the air compressor 1, and the other end extends towards the train car 4. The extending end of the first compressed air pipe 3 is connected to the connecting flexible pipe 7. Each train car 4 of the aligned train is provided with the second compressed air pipe 10. Each second compressed air pipe 10 is connected to the air inlet port of the air brake 9 of the corresponding train car 4, so as to ensure that the compressed air in the second compressed air pipe 10 can be input into the air brake 9. The two ends of the second compressed air pipe 10 are respectively connected to the connecting flexible pipe 7. The connecting flexible pipes 7 between the tractor 2 and the train cars 4 or between two train cars 4 are connected through the handshake valve 8. The handshake valve 8 is a key device for connecting the first compressed air pipe 3 of the tractor 2 and the second compressed air pipe 10 of the train car 4 or the second compressed air pipe 10 of the adjacent train car 4, and has two states of connection and disconnection. The input end of the handshake valve 8 is connected to the first compressed air pipe 3 or the second compressed air pipe 10 of the previous train car 4 through the connecting flexible pipe 7, and the output end is connected to the second compressed air pipe 10 of the next train car 4 through the connecting flexible pipe 7. In order to facilitate the installation and removal of the connecting flexible pipe 7, one end of the first compressed air pipe 3 extends out of the tractor 2 by a distance, and the two ends of the second compressed air pipe 10 extend out of the corresponding train cars 4. The connecting flexible pipe 7 of the present embodiment is made of rubber flexible pipe, which has good flexibility and sealing performance.

[0020] In some possible embodiments, the first compressed air pipe 3 is provided with a compressed air valve. Preferably, two compressed air valves are provided, i.e. a first compressed air valve 5 installed near the air outlet of the air compressor 1 and a second compressed air valve 6 installed on the extending section of the first compressed air pipe 3. The first compressed air valve 5 is used to control the air flow between the air compressor 1 and the compressed air pipe, and the second compressed air valve 6 is used to control the air flow between the compressed air pipe and the handshake valve 8. The purpose of providing two compressed air valves is to realize segmented control, so as to completely block the air flow in the non-working state and avoid air leakage, and to be able to adjust the air pressure in segments in the working state, thereby improving the safety and reliability of the system.

[0021] When the air charging device is used, if part of the train car 4 is in a braking state due to air leakage during the process of the tractor 2 pulling the train car, the operator can manually switch the hand valve 8 to the connected state and open the first compressed air valve 5 and the second compressed air valve 6. Then start the air compressor 1 configured by the tractor 2 to make it normally operate. The compressed air generated by the air compressor 1 is transmitted to the air inlet port of the car air brake 9 through the first compressed air valve 5, the first compressed air pipe 3, the second compressed air valve 6, the connecting flexible pipe 7, the hand valve 8, the other connecting flexible pipe 7 and the second compressed air pipe 10 in sequence. If the first train car 4 leaks, the compressed air will be preferentially supplemented to the car air brake 9 of the car, until the air pressure reaches the set value (i.e. full air state), and the braking state is released. If the single or multiple train cars 4 behind leak, the compressed air will be transmitted to the second compressed air pipe 10 of the leaking car through the hand valve 8 and the connecting flexible pipe 7 in sequence, and supplemented to the air inlet port of the car air brake 9. When the air pressure of the leaking car reaches the set value, the braking state is released, and the compressed air continues to be transmitted backward until the air pressure of all cars returns to the normal working state, and the tractor 2 can normally pull the train car 4 to run on the track.

[0022] The utility model provides a kind of efficient, reliable and easy-to-operate tractor air charging device based on train air brake system, which can quickly supplement compressed air to the car air brake of leaking car when the train car leaks and causes brake lock, whether air leakage occurs in the first section or single or multiple train cars, the braking state of the whole train can be released, ensuring that the tractor can normally pull the train car to run on the track, significantly improving the operating efficiency.
