DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1-6As shown, a wireless exhaust device for realizing emergency parking of a railway locomotive includes: a guide frame 2, the main body of the guide frame 2 is arranged longitudinally, and every two longitudinally adjacent guide frames 2 form a group, and the outer sides of the three groups of guide frames 2 are fixedly connected with guide blocks 201 with a raised structure, and the bottom end surface of the guide frame 2 is fixedly connected with a spring rod 210, and the inner side of each group of guide frames 2 is also fixedly connected with a piston 202 with a cylindrical structure, and the bottom end of the piston 202 is provided with a through hole, which is used for air intake, and the outer peripheral surface of the piston 202 is provided with an air outlet 204 that is bidirectionally connected on the front and rear sides, and the air outlet 204 is connected to the air inlet 203, and the top surface of the piston 202 is fixedly connected with a mounting frame 205, and a servo motor 206 is installed inside the mounting frame 205. The top end of the servo motor 206 is installed with an output shaft, and a limit rod 207 is installed on the output shaft, and a guide ball 208 is rollingly connected to the top surface of the limit rod 207.

[0025] Among them, the guide frame 2 is slidably connected to the inner position of the bellows 1 through the guide block 201 fixedly connected on its outer surface, and a limit frame 209 is fixedly connected to the top surface of the bellows 1, and the limit frame 209 is used to limit the limit rod 207. A through hole is opened on the right side of the bellows 1, and the air supply pipe 101 is fixedly connected to the inside of the through hole. A mounting plate 3 is fixedly connected to the top surface of the piston 202 on the left. There are two mounting plates 3. The inner sides of the two mounting plates 3 are rotatably connected with the shift rod 301. The top and side of the bellows 1 are respectively fixedly connected with a sealing ring 105 and a connecting plate 106.

[0026] Among them, a flange 102 is fixedly connected to the right side of the air supply pipe 101, and a through-hole is opened inside the flange 102 in a circular array, and a machine controller 103 is fixedly connected to the left side of the bellows 1. The interior of the machine controller 103 includes at least a receiving module, a processing module and a transmitting module. The machine controller 103 is installed with a switch 104 through a wire fixedly connected to the top surface thereof. The switch 104 is integrated in the train cab. A mounting hole 302 is opened on the side of the lever 301 away from the mounting plate 3. A limiting support plate 304 is fixedly connected to the top surface of the bellows 1, and a notch is opened inside the limiting support plate 304. A limiting protrusion 303 is fixedly connected to the outer side of the lever 301.

[0027] When in use, when the railway locomotive is in use, the bellows 1 is connected to the external air supply pipe by using the air supply pipe 101 and the flange 102 fixedly connected on its right end face, and the gas is simultaneously allowed to enter the interior of the bellows 1 for temporary storage, and the piston 202 is opened for exhaust in the following three ways;

[0028] First, when all the electric control structures fail, the lever 301 provided on the inner side of the mounting plate 3 is directly rotated so that the limiting protrusion 303 fixedly connected to the outer side of the lever 301 is removed from the inside of the limiting support plate 304 fixedly connected to the top surface of the bellows 1, so that the piston 202 can be ejected upward under the discharge action of the spring rod 210 provided on the bottom surface of the guide frame 2, so that the gas in the bellows 1 can be quickly released through the air inlet 203 and the air outlet 204;

[0029] Secondly, when an emergency occurs through remote electronic control, the driver broadcasts the emergency stop signal through the handheld button, and the machine controller 103 set on the left end surface of the bellows 1 receives the emergency stop signal broadcast by the handheld button and sends an exhaust command to the exhaust valve through the RS232 serial communication method. At this time, the servo motor 206 installed in the mounting bracket 205 is started to rotate the limit rod 207, so that the limit rod 207 is taken out from the inside of the limit bracket 209 under the rolling action of the guide ball 208 installed on its top surface, so that the piston 202 can be displaced upward to release the air. The whistle is sounded to remind the driver, and the status information is fed back to the machine controller 103 in real time. The status information includes the open or closed status of the piston 202 and the wind pressure status detected by the barometer in the piston 202. At this time, the locomotive is in the exhaust state, and the air cylinder pressure gradually decreases from 500kPa to 0kPa. After receiving the status feedback of the piston 202, the machine controller 103 ensures that the exhaust is completed, and then broadcasts the emergency stop voice to the driver, entering the emergency braking state. Another way is to directly open the switch 104 set at the top of the machine controller 103 and repeat the deflation operation to achieve the deflation operation inside the cab;

[0030] When the emergency situation is resolved, the driver broadcasts the unlock signal through the handheld button. The machine controller 103 receives the unlock signal broadcast by the handheld and sends a release exhaust command to the piston 202 through the RS232 serial communication mode. After the piston 202 has completed the air release, it will close and sound a horn to remind the driver. The status information will be fed back to the machine controller 103. The status information includes the open or closed status of the piston 202 and the air pressure status detected by the barometer in the piston 202. After the machine controller 103 receives the response command from the piston 202 and confirms that the closure is successful, it will broadcast the unlocking voice to the driver, release the emergency brake state, and the shunting driver can charge the air. The air pressure will return to 500kPa and the driving operation will be started. The synchronized piston 202 will send heartbeat data regularly through RS232 serial communication. When the machine controller 103 does not receive the heartbeat data of the exhaust valve for more than 10s, it indicates that the wired communication is abnormal and a fault alarm will be issued. Manual intervention is required to troubleshoot the hardware problem. During the driving operation, the barometer in the piston 202 will regularly feed back the air pressure data to the machine controller 103 in real time. When the machine controller 103 is in the non-parking state and recognizes that the air pressure is abnormally lower than 400kPa, a fault alarm will be issued and manual intervention is required to troubleshoot the hardware problem.
