[0026] The unhooking rod includes an unhooking rod 6, which is installed at the bottom of the lever 3. The two ends of the unhooking rod 6 are respectively provided with a first flexible connector 5 and a second flexible connector 4. The first flexible connector 5 and the second flexible connector 4 can be adjusted in length during the unhooking process to cooperate with different types of car couplers for unhooking or hooking.

[0027] The output end of the pneumatic unhooking module 1 is connected to one end of the lever 3. The other end of the lever 3 is connected to one end of the unhooking rod 6 through the first flexible connector 5. The other end of the unhooking rod 6 is connected to the coupler 2 through the second flexible connector 4. The pneumatic unhooking module 1 provides power to drive the lever 3 and the unhooking rod to move. Under the action of the lever 3 and the unhooking rod, the unhooking rod 6 of the unhooking rod engages with the locking tongue of the coupler 2 to achieve automatic unhooking or coupling.

[0028] The lever 3 is mounted on the lever seat in the middle, and the lever seat is located at the bottom of the pneumatic unhooking module 1. The lever seat is a triangular bracket structure. One end of the lever seat is mounted on the connecting bracket, and the other end of the lever seat is connected to the lever 3. The unhooking rod 6 is located at the bottom of the lever 3. The unhooking rod 6 is mounted on the unhooking mounting seat, and the unhooking mounting seat is located at the bottom of the lever 3. The unhooking mounting seat is a U-shaped frame structure.

[0029] Furthermore, the unhooking rod 6 is a "ㄣ"-shaped unhooking rod 6, with a vertical connecting rod vertically arranged near one end of the unhooking rod 6. One end of the vertical connecting rod is connected to the unhooking rod 6, and the other end of the vertical connecting rod is connected to the lever 3 through the first flexible connector 5. A handle is installed at one end of the unhooking rod 6 for manual unhooking when the automatic unhooking fails.

[0030] The first flexible connector 5 and the second flexible connector 4 are both adjustable high-strength alloy chains;

[0031] It should be noted that both the first flexible connector 5 and the second flexible connector 4 are adjustable high-strength alloy chains. The connection between their chain links adopts an anti-detachment structure to prevent the chain from falling off during the unhooking process. In addition, the length of the first flexible connector 5 is adjustable to adapt to the pulling stroke requirements of the unhooking rod 6 when unhooking different couplers 2.

[0032] Furthermore, the pneumatic unhooking module 1 includes a cylinder 8, in which a piston rod is installed, one end of which is connected to the lever 3; wherein, the other end of the piston rod is installed on the cylinder 8; the input end of the cylinder 8 is connected to compressed air through an air supply pipeline to provide a power source for the cylinder 8;

[0033] Furthermore, a solenoid valve 13 is installed on the air supply pipeline. The solenoid valve is connected to the locomotive control system and is used to receive signals from the locomotive control system through the solenoid valve 13 to open the air supply pipeline and control the piston rod of the cylinder 8 to move.

[0034] Furthermore, a pressure stabilizing tank 11 and a pressure regulating valve 12 are also installed on the air supply pipeline; the pressure stabilizing tank 11 is equipped with a pressure monitoring device, and the control system is also connected to the pressure monitoring device and the pressure regulating valve 12 to control the air pressure in the air supply pipeline. At the same time, the pressure stabilizing tank 11 is also used to store compressed air, providing a power source to achieve automatic unhooking or hooking when the vehicle has no air source, and adjusting the air pressure in the air supply pipeline through the pressure regulating valve 12.

[0035] It should be noted that the pressure stabilizing tank 11 is equipped with a pressure monitoring device, which is a pressure sensor. The control system is connected to the pressure sensor and is used to control the air pressure in the air supply pipeline to remain stable within a set range. When the air pressure in the air supply pipeline is lower than the set minimum value, the pressure monitoring device sends a signal to control the external air source to replenish the air supply pipeline. When the air pressure in the air supply pipeline is higher than the set maximum value, the pressure monitoring device controls the pressure stabilizing tank 11 to release air in order to maintain the air pressure in the air supply pipeline stable within the set range.

[0036] Furthermore, a first proximity switch 9 and a second proximity switch 10 are installed on both sides of the cylinder 8. The control system is also connected to the first proximity switch 9 and the second proximity switch 10. The first proximity switch 9 and the second proximity switch 10 sense the position change of the cylinder piston rod and send a feedback signal to the control system. The control system confirms the feedback signal. When the cylinder piston rod extends to the maximum position of its stroke, the proximity switch 10 senses the change in the piston rod position and sends a feedback signal to the control system. The control system confirms that the coupler 2 has been automatically unhooked. When the cylinder piston rod retracts to the minimum position of its stroke, the first proximity switch 9 senses the change in the piston rod position and sends a feedback signal to the control system. The control system confirms that the coupler 2 has been automatically engaged.

[0037] Furthermore, the first proximity switch 9 and the second proximity switch 10 are electromagnetic induction type, photoelectric induction type, or capacitive induction type proximity switches.

[0038] Furthermore, the solenoid valve 13 is a solenoid directional valve, which controls the extension and retraction direction of the piston rod installed in the cylinder 8 by reversing, thereby achieving precise control of the unhooking action and the piston rod reset action.

[0039] Furthermore, the cylinder 8 is a double-acting cylinder 8, which can provide power in both directions to ensure that the coupler 2 can work stably during the piston rod reset process after uncoupling and coupling.

[0040] It should be noted that the solenoid valve 13 of cylinder 8 is connected to the control system to control the piston rod. The piston rod's movement drives the lever 3 and the first flexible connector 5. Under the action of the lever 3 and the first flexible connector 5, the unhooking rod 6 moves to engage with the locking tongue of the coupler 2 to achieve automatic unhooking or engagement. The output end of the piston rod is connected to one end of the lever 3, and the other end of the lever 3 is connected to one end of the unhooking rod 6 through the first flexible connector 5. One end of the unhooking rod 6 is connected to the coupler 2 through the second flexible connector 4. Both the first flexible connector 5 and the second flexible connector 4 are adjustable high-strength alloy chains to adapt to the different requirements of the unhooking rod 6's pulling stroke when unhooking the coupler 2. They can be adapted to the unhooking rod 6 of different couplers 2, have strong versatility, and use cylinder 8 and the control system to control the unhooking rod 6 to achieve automatic unhooking or engagement of the coupler 2, reducing the labor intensity of workers and improving efficiency.

[0041] The pneumatic unhooking module 1 has a lever seat 7 at its bottom, and the lever 3 is mounted on the lever seat 7; the piston rod of the cylinder 8 is connected to one end of the lever 3 to provide unhooking power; the other end of the lever 3 is connected to the unhooking rod 6 through the first flexible connector 5.

[0042] The pneumatic unhooking module 1 includes a cylinder 8, in which a piston rod is installed. Compressed air is connected to the cylinder 8 through an air supply line. The piston rod of the cylinder 8 is connected to one end of a lever 3 to provide unhooking power. The lever 3 is mounted on a lever seat 7, and the other end of the lever 3 is connected to one end of an unhooking rod 6 through a first flexible connector 5 to ensure that the movement of the piston rod can be smoothly transmitted to the lever 3. When connecting, the length and tension of the first flexible connector 5 should be adjusted to ensure that the first flexible connector 5 can effectively pull the unhooking rod 6 during the unhooking process without loosening or falling off. The unhooking rod 6 is pulled by lever 3 and the first flexible connector 5 using the lever 3 principle. The other end of the unhooking rod 6 is connected to the car coupler 2 through a second flexible connector 4. Through the action of lever 3 and the first flexible connector 5, the raised end of lever 3 pulls the unhooking rod 6 away from the locking tongue through the first flexible connector 5, completing the unhooking action.

[0043] A solenoid valve 13 is installed on the air supply line. The control system is connected to the solenoid valve 13. Cylinder 8 provides the uncoupling power. When the coupler 2 needs to be opened, the locomotive control system sends an uncoupling signal, controlling the solenoid valve 13 of cylinder 8 to open the air supply line. The piston rod in cylinder 8 begins to move, pushing the uncoupling rod 6 to complete the uncoupling. Specifically, the piston rod in cylinder 8 moves, pushing one end of lever 3, causing the other end of lever 3 to lift. The lifted end of lever 3 pulls the uncoupling rod 6 through the first flexible connector 5 to complete the uncoupling action. At the same time as the uncoupling is completed, the second proximity switch 10 lights up, and the first proximity switch 9 goes out. After receiving the signal, the locomotive control system confirms that the coupler 2 has been successfully uncoupled. After the coupler 2 completes automatic coupling, the uncoupling rod 6 is brought to the self-locking position by the locking tongue, and the piston rod in cylinder 8 also returns to its original position. At this time, the second proximity switch 10 goes out, and the first proximity switch 9 lights up. After receiving the signal, the locomotive control system confirms that the coupler 2 has been successfully coupled.

[0044] The locomotive uncoupling device further includes a connecting bracket, which is a rectangular housing with one open end. The cylinder 8, pressure stabilizing tank 11, solenoid valve 13, pressure regulating valve 12, first proximity switch 9, and second proximity switch 10 are all installed inside the rectangular housing. The connecting bracket is used to install the pneumatic uncoupling module 1 onto the existing coupler 2 system. The connecting bracket has multiple installation interfaces to adapt to the installation requirements of different coupler 2 systems. A lever 3 is provided at the bottom of the connecting bracket. One end of the lever 3 is located inside the connecting bracket and is connected to the output end of the piston rod of the cylinder 8.

Under the action of the lever 3 and the unhooking rod, the unhooking rod 6 of the unhooking rod engages with the locking tongue of the coupler 2 to achieve automatic unhooking or coupling; the pneumatic unhooking module 1 is set to provide unhooking power, and by utilizing the lever principle, the automatic unhooking or coupling action of the coupler is completed through the action of the lever and the unhooking rod, which improves the efficiency of manual unhooking and reduces labor intensity and risk.
