[0037] See Figures 1 to 4 、 Figures 12 to 16As shown in the figure, an embodiment of the present application provides a wind pipe removal and pin extraction system, including: a mobile device 100 and a wind pipe removal and pin extraction device 200; wherein, the mobile device 100 includes a vehicle chassis 1001 and a transverse movement mechanism 1002. The transverse movement mechanism 1002 is arranged on the vehicle chassis 1001, and the vehicle chassis 1001 drives the transverse movement mechanism 1002 to move along a first preset direction a; the wind pipe removal and pin extraction device 200 includes a support member 201, a flipping drive device 202, a flipping arm 203, a lifting drive device 204, a lifting transmission mechanism 205 and an operating member 206; the support member 201 is connected to the transverse movement mechanism 1002, and the transverse movement mechanism 1002 is used to drive the support member 201 to move along a second preset direction b; the fixed end of the flipping drive device 202 is connected to the support member 201, and the drive end of the flipping drive device 202 is connected to the flipping arm 203; The fixed end of the lifting drive device 204 is connected to the flipping arm 203, and the drive end of the lifting drive device 204 is connected to the operating member 206 through the lifting transmission mechanism 205. The operating member 206 is used to connect the parts to be removed on the vehicle body 1; the flipping drive device 202 can drive the operating member 206 to flip within a preset angle range, and the lifting drive device 204 can drive the operating member 206 to lift along a third preset direction c to remove the parts to be removed on the vehicle body 1.

[0038] In this embodiment, the wind pipe removal and pin extraction device 200 can be used to realize the actions of wind pipe removal and pin extraction: (1) Action of removing the wind pipe The mobile device 100 drives the wind pipe removal and pin extraction device 200 to move along the track to the connection between two carriages 400. The transverse movement mechanism 1002 drives the wind pipe removal and pin extraction device 200 to move horizontally under the train wind pipe 600. The flipping drive device 202 drives the flipping arm 203 to flip 90°, rotating from the horizontal state to the vertical state. At this time, the operating member 206, such as the hook head 2062 of the wind pipe, is directly below the joint of the wind pipe 600. The lifting drive device 204 drives the hook head 2062 to move upward. According to the railway uncoupling process, when the joint of the wind pipe 600 is lifted, the wind pipe 600 will be gradually uncoupled, thus completing the action of removing the wind pipe.

[0039] (2) Action of extracting the pin The mobile device 100 drives the uncoupling pipe pin-pulling device 200 along the track to move to the connection between two carriages 400. The transverse movement mechanism 1002 drives the uncoupling pipe pin-pulling device 200 to move horizontally to the lower part of the anti-hopping pin 500. The flipping drive device 202 drives the flipping arm 203 to flip by 90°, rotating from the horizontal state to the vertical state. At this time, the pin-pulling head 2063 is located below the anti-hopping pin 500, and the horizontal distance from the anti-hopping pin 500 is about 50 mm. The lifting drive device 204 drives the pin-pulling head 2063 to move upward. When it moves to the same vertical height as the pin, the vehicle chassis moves forward to perform the pin-hooking action. At this time, the pin-pulling head 2063 is inserted into the hook ring of the anti-hopping pin 500. The transverse movement mechanism 1002 drives the uncoupling pipe pin-pulling device 200 to move horizontally. According to the railway uncoupling process, when the transverse movement distance reaches 150 mm, the pin-pulling action is completed.

[0040] It can be seen that the present application provides a device for assisting the operation of uncoupling the air pipe and pulling the pin, which can effectively reduce the labor intensity of workers and improve safety.

[0106] In summary, the detailed working steps of the air duct uncoupling pin device 200 provided by the present application are as follows: (1) Action of the air duct After the mobile device 100 stops parking, the vision camera performs secondary recognition on the joint features of the air duct 600. According to the recognized position result, the mobile device 100 moves to the specified position, and the transverse movement mechanism 1002 drives the air duct uncoupling pin device 200 of the present invention to move horizontally to the lower part of the train air duct 600. The flipping driving device 202 drives the flipping arm 203 to flip 90°, rotating from the horizontal state to the vertical state. At this time, the operating member 206, such as the hook head 2062 of the air duct, is located directly below the joint of the air duct 600. The lifting driving device 204 drives the hook head 2062 to move upward. According to the railway uncoupling process, when the joint of the air duct 600 is lifted, the air duct 600 will be gradually uncoupled, thus completing the action of uncoupling the air duct.

[0107] (2) Action of pulling out the pin After the mobile device 100 stops, the vision camera performs secondary recognition on the features of the anti-jump pin 500. According to the recognized position result, the mobile device 100 moves to the designated position, and the flipping drive device 202 drives the flipping arm 203 to flip 90°, rotating from the horizontal state to the vertical state. At this time, the pin-pulling head 2063 is located below the anti-jump pin 500, and the horizontal distance from the anti-jump pin 500 is about 50 mm. The lifting drive device 204 drives the pin-pulling head 2063 to move upward. When it moves to the same height as the pin vertically, the mobile device 100 moves forward to perform the pin-hooking action. At this time, the pin-pulling head 2063 is inserted into the hook of the anti-jump pin 500, and the transverse movement mechanism 1002 drives the air pipe pin-pulling device 200 of the present invention to move horizontally. According to the railway uncoupling process, when the transverse movement distance reaches 150 mm, the pin-pulling action is completed.

[0108] As can be seen from the above, the air pipe pin-pulling device 200 of the present invention can not only assist in the action of detaching the air pipe, but also assist in pin-pulling, effectively reducing the labor intensity of workers and improving safety.
