Description

Technical Field

[0001] The present application relates to the technical field of rail vehicles, and in particular to a rail vehicle air storage cylinder and a rail vehicle. Background Art

[0002] Each rail vehicle is equipped with a main air cylinder, a brake air cylinder and an auxiliary air cylinder. A drain valve is installed under each air cylinder. These drain valves are used to remove condensed water from the water vapor in the air cylinder. These air cylinders are installed under the vehicle body. During the commissioning and operation and maintenance of rail vehicles, it is necessary to regularly remove the condensed water and compressed air from the air cylinder; specifically, during the commissioning process, when debugging the brake system, it is necessary to manually remove the compressed air in the air cylinder, and during the operation and maintenance process, it is necessary to manually remove the condensed water in the air cylinder.

[0003] Moreover, in cold weather, when the rail vehicle is debugged or maintained, the condensed water in the drain valve below the air storage cylinder often freezes. When the air storage cylinder is operated manually, it is inconvenient to discharge the condensed water in the air cylinder, and it needs to be removed by additional heating equipment or de-icing equipment. The operation is cumbersome, and the operation or debugging time is increased, the operation efficiency is reduced, and the manual labor intensity is high.

[0004] Secondly, when the rail vehicle is being debugged, the air cylinder needs to be exhausted by removing the bottom plate of the equipment cabin so that the air cylinder can be operated manually. The removal of the bottom plate of the equipment cabin requires 4 employees to operate, and they need to manually enter the trench of the rail vehicle to manually operate the air cylinder drain valve. If the vehicle is not placed on a track with an inspection trench, but is placed on a parking lane, it is necessary to manually open the vehicle skirt and manually drill into the skirt bracket to perform manual operations. After opening the bottom plate or skirt of the equipment cabin, manually drill into the tunnel or skirt, use a four-corner key or a triangular key, and rotate the drain valve clockwise to open it, discharge the compressed air in the air cylinder, and also discharge the condensed water in the air cylinder. After the compressed air is discharged, it is necessary to manually drill into the tunnel or skirt, and then use a four-corner key or a triangular key to rotate the drain valve counterclockwise to close it, which is labor-intensive.

[0082] The specific operation process of the exhaust valve assembly 203 is as follows: when the rail vehicle is in operation, the rail vehicle air storage cylinder 200 is installed under the vehicle body. When the rail vehicle is in operation, the device also runs at high speed with the vehicle; the first control valve 2031 is closed, and the second control valve 2032 is opened. Since the rail vehicle is in high-speed operation, the high-speed airflow will flow through the bottom of the vehicle body, and the high-speed airflow flows in the direction of the fan generator 2033-cross pipe 2034-second control valve. The fan in the fan generator 2033 rotates at high speed under the drive of the high-speed airflow, and the fan drives the generator to generate electricity, converting the mechanical energy of the high-speed operation of the airflow into electrical energy; since two fan generators 2033 in the front and rear directions are installed on both sides of the air storage cylinder, no matter in which direction the vehicle is running, this fan generator 2033 can convert the mechanical energy of the vehicle into electrical energy to supply power to the entire device.

[0083] When the rail vehicle is in a stationary state and power needs to be supplied to the device, the first control valve 2031 is controlled to be opened and the second control valve 2032 is controlled to be closed. The air in the air storage cylinder body 201 flows through the first control valve 2031, the cross pipe 2034 and the fan generator 2033. The fan in the fan generator 2033 rotates at high speed driven by the high-speed airflow, and the fan drives the generator to generate electricity, thereby converting the mechanical energy of the high-speed airflow into electrical energy.

[0084] The specific operation process of the drain valve assembly 202 is as follows: when the rail vehicle is stored outdoors in a cold environment for a long time in a stationary state, the condensed water in the drain valve body 2021 will freeze under low temperature conditions; the second control valve 2032 is closed and the first control valve 2031 is opened through the auxiliary operation device 100 for the air storage cylinder drain valve, and the compressed gas in the air storage cylinder body 201 will form a channel through the first control valve 2031, the cross pipe 2034 and the fan generator 2033, and the compressed gas will be discharged into the atmosphere through the above-mentioned pipe channel; when the high-pressure gas passes through the fan generator 2033 at a high speed, the high-speed running gas will drive the fan to rotate at a high speed, and the fan drives the generator to operate, converting the kinetic energy of the high-speed running gas into electrical energy; the converted electrical energy is used to power the microwave controller 202216, the microwave generator, the heating conductor 202213 and the control device; since a fast deicing operation is required, the microwave controller 202216 is powered on at this time, and the microwave controller 202216 controls the microwave The generator emits microwaves, and the generated microwaves will be emitted through the 14 microwave emission holes 202215 of the water drop-shaped heating body 20221; the emitted microwaves will be reflected through the cavity wall in the body of the drain valve body 2021, reflected to the iced area, and the frozen condensed water will be de-iced; the operator can observe the pressure change inside the drain valve body 2021 through the color change of the pressure-sensitive coating in the observation window 202218. When the pressure change inside the drain valve body 2021 is zero, the drain valve opening and closing actuator 20242 will be connected through the auxiliary operation device 100 for the air storage cylinder drain valve to open the drain valve assembly 202. Since the condensed water has been de-iced before opening, the condensed water will be discharged to the ground through the drain valve assembly 202 under the action of gravity. The auxiliary operation device 100 for the air storage cylinder drain valve will be connected to the drain valve opening and closing actuator 20242 to close the opened drain valve assembly 202. At this time, the drainage operation of the rail vehicle air storage cylinder 200 drain valve is completed.

[0085] Based on the rail vehicle air storage cylinder provided in the above embodiment, the present application also provides a rail vehicle including the above rail vehicle air storage cylinder, and the rail vehicle also includes a vehicle body and an auxiliary operating device for an air storage cylinder drain valve; the vehicle air storage cylinder is located below the vehicle body, and the auxiliary operating device for the air storage cylinder drain valve is used to open and close the drain valve assembly of the rail vehicle air storage cylinder.

[0086] See also Figure 12-13 In a specific embodiment, the auxiliary operation device for measuring the drain valve of the air storage cylinder provided by the present application includes:

[0087] An arm 1 that is axially retractable and fixed;

[0088] The opening and closing component 2 is used to open and lock the drain valve assembly, and the opening and closing component 2 is located at the shaft end of the arm 1;

[0089] The deicing assembly 4 is fixed to the shaft end of the arm 1 and is used for deicing the drain valve assembly after ice formation.

[0090] The arm 1 can be extended and fixed along its own axis. The extension length of the arm 1 is adjusted according to the lateral position of the drain valve assembly on the rail vehicle, so that the opening and closing component 2 can be extended into the track to realize the opening and closing operation of the drain valve assembly. Thereby, there is no need for operators to enter the ditch or skirt of the rail vehicle, which prevents dust and sand from flying into the eyes during manual operation, reduces the probability of work-related accidents, and reduces labor costs and labor intensity.

[0091] The opening and closing component 2 can open and lock the drain valve assembly. If the locking structure of the drain valve assembly is set as a triangular lock or a four-corner lock, it can be adjusted and converted according to the shape of the locking structure of the drain valve assembly. After being connected with the locking structure of the drain valve assembly, the arm 1 is rotated along its own axis to convert the rotational force generated by the arm 1 into the opening and closing force of the locking structure of the drain valve assembly, thereby realizing the conversion and transmission of the operating rotational force.

[0093] The de-icing assembly 4 is fixed to the arm 1 with a fastening bolt. The fastening bolt is a customized cylindrical metal bolt with a 4mm stud at the front end and a regular hexagonal structure at the rear end for rotating the fastening bolt.

The opening and closing component 2 is sent into the track through the axial extension and contraction movement of the arm 1, and the opening and closing component is connected to the locking structure of the drain valve assembly. The arm 1 is rotated around its own axis to drive the opening and closing component 2 to rotate to open and close the drain valve assembly. It does not require operators to drill into the track or the skirt bracket to operate, thereby reducing manual operation costs and labor intensity, and improving the operating efficiency of the drain valve assembly; at the same time, the deicing operation of the drain valve assembly is performed through the deicing component 4, which shortens the deicing time, improves the deicing efficiency, and further reduces labor costs and labor intensity.
