The coupler consists of three parts: the hook head, the hook body, and the hook tail. The thick part at the front end of the coupler is called the hook head. The hook tongue is hinged in the hook head. The hook tongue can swing and is fixed by the hook pin. In order to achieve hooking or unhooking, and connect or separate vehicles, the coupler has the following three positions, that is, the three states of the coupler: locked position - the position where the hook tongue of the coupler is blocked by the hook pin and cannot be turned outward. The coupler is in this position when two vehicles are connected together; open position - the position where the hook pin is lifted and the hook tongue can be turned outward as long as it is pulled.

[0042] The telescopic cylinder is an electric cylinder, a hydraulic cylinder or a gas cylinder. In addition, the alternative solution is that the hook opening component includes a motor, and one end of the rotating handle 7 extends out of the mounting bracket 3 and is connected to the motor transmission.

[0043] The mounting bracket 3 is detachably fixedly mounted on the hook head.

[0044] The hook opening drive component 2 also includes a slider 4, which is fixedly connected to the hook pin, and the slider 4 is slidably connected to the mounting bracket 3. The mounting bracket 3 is provided with a sliding groove or a sliding hole that matches the slider 4. The first sensor 51 is installed on the mounting bracket 3 and is used to detect the position of the slider 4 when the hook tongue is in a locked state. The second sensor 52 is installed on the mounting bracket 3 and is used to detect the position of the slider 4 when the hook tongue is in a fully open state.

[0047] The auxiliary bracket 9 is detachably fixedly connected or threadedly connected to the hook tongue.

[0048] The locomotive also includes a controller, which is electrically connected to the first sensor 51, the second sensor 52, and the driving component 2. The controller is an industrial computer or a PLC, which is arranged in the locomotive and electrically connected to the driving component 2 through wires.

[0049] The mounting bracket 3 is fixed to the hook head and is used to mount the driving component 2, the rotating handle 7, the first sensor 51, the second sensor 52 and other components; the slider 4 is arranged on the hook pin through the mounting bracket 3 to limit the vertical movement of the hook pin and to transmit the position of the hook pin; the auxiliary bracket 9 is arranged on the hook tongue through the mounting bracket 3, mainly used to transmit the position of the hook tongue; the detection bracket 8 is arranged on the mounting bracket 3 by bolts and is used to mount the third sensor 53 and the fourth sensor 54. When the above parts are in different positions, the coupler 1 can realize three states: locked, unlocked and fully opened.

[0050] Before hooking, the fourth sensor 54 detects the hook tongue position signal from the auxiliary bracket 9 to determine whether the hook tongue is fully opened; if it is not fully opened, the controller controls the driving component 2 to drive the rotating handle 7 to rotate, and lifts the connecting chain 6 under the action of the force arm to lift the hook pin, and the hook tongue opens under the action of the hook head part in the coupler 1. After the fourth sensor 54 receives the hook tongue position signal transmitted from the auxiliary bracket 9, it feeds back to the controller, the driving component 2 stops and retreats, and the hook pin returns to the middle position to prepare for hooking; during hooking, the hook tongue begins to close under the action of the opposing coupler 1, the third sensor 53 receives the hook tongue position signal transmitted from the auxiliary bracket 9, and the first sensor 51 receives the hook pin position signal transmitted from the slider 4, which means that the hooking is completed and the locomotive can run.

[0051] When unhooking, the driving component 2 acts to drive the rotating handle 7 to rotate, and the connecting chain 6 is lifted under the action of the force arm, so that the hook pin is lifted to the unlocking position. After the second sensor 52 receives the hook pin position signal transmitted by the slider 4, the locomotive runs to drive the coupler 1 to disengage, and the fourth sensor 54 detects the signal to determine whether the hook tongue is fully opened. The controller controls the driving component 2 to fully act, so that the hook tongue is fully opened, and retracted after fully acting to prepare for the next hooking.

[0052] The present application can realize automatic unhooking through electrical control, and at the same time, the system does not interfere with the original locomotive manual hook-lifting rod unhooking system, thereby avoiding the unhooking action being unable to be performed due to a failure of the automatic unhooking system.

[0053] Embodiment 2: A method for using an automatic hook removing device comprises the following steps:

[0054] Step 1: When the hook needs to be removed, the hook tongue is in a locked state, and the controller sends a command to the driving component 2;

[0056] Step 3: When the second sensor 52 detects the hook pin position signal transmitted by the slider 4, it is fed back to the controller, and the controller determines that the hook tongue is in a fully open state. At this time, the locomotive can be operated to drive the coupler 1 to disengage;

[0057] Step 4: If the locomotive stops running, the action ends and waits for the next hooking; when the locomotive needs to hook, proceed to step 5;

[0058] Step 5: Use the third sensor 53 and the fourth sensor 54 to detect the state of the hook tongue. If the fourth sensor 54 does not detect the hook tongue position signal transmitted by the auxiliary bracket 9, the controller determines that the hook tongue is in an unlocked state rather than a fully open state, and then proceeds to step 6; if the fourth sensor 54 detects the hook tongue position signal transmitted by the auxiliary bracket 9, the controller determines that the hook tongue is in a fully open state, and then proceeds to step 7;

[0059] Step 6: The controller sends a command to the driving component 2. After receiving the command, the driving component 2 drives the rotating handle 7 to rotate, the connecting chain 6 continues to be pulled up, and the hook pin continues to be pulled out, until the fourth sensor 54 detects the hook pin position signal transmitted by the slider 4, and then proceeds to step 7;

[0060] Step 7: The controller sends a command to the driving component 2, and the driving component 2 drives the rotating handle 7 to stop rotating. Then the rotating handle 7 rotates in the opposite direction compared with step 6, the connecting chain 6 stops pulling up and retracts, and the hook pin returns to the middle position to prepare for hooking;

[0061] Step eight, perform the hooking operation. The hook tongue begins to close under the action of the coupler 1.
