[0030] The base 1 is used to connect to the coupler electrical head 5, and the measuring element 2 is connected to the side of the base 1 away from the coupler electrical head 5. Preferably, both the base 1 and the measuring element 2 are made of aluminum alloy.

[0031] A level measuring instrument 4 is fixedly connected to the measuring component 2. Both sides of the base 1 have flanges 11 extending toward the coupler electrical head 5. The ends of the flanges 11 form a contact surface. Magnets 3 are fixedly connected at intervals on the contact surface for adsorbing onto the coupler electrical head 5. Preferably, the contact surface of the flanges 11 is set perpendicular to the level measuring instrument 4.

[0032] Specifically, the two sides of the coupler electrical head 5 are made of flat iron material. Three neodymium iron boron magnets with a length, width and thickness of 5*6*2mm are evenly pasted on the contact surface between the flange 11 of the base 1 and the coupler electrical head 5. They are connected to the metal frame of the coupler electrical head 5 by magnetic force to fix the detection device. The thickness of the base 1 body is 6mm, and the length and width are adapted to the width of the metal shell of the coupler electrical head 5. The flange 11 is 40mm high, and the length of the T-slot 12 is 250mm.

[0033] Preferably, the measuring component 2 is constructed as a right-angled triangle, and the height of the measuring component 2 is less than the length of the base 1. The measuring component 2 has a mounting groove parallel to the long side above its long side for mounting the level measuring instrument 4. Preferably, the level measuring instrument 4 is a graduated bubble level measuring instrument with the center point of the bubble level measuring instrument as the zero point. The scale extends symmetrically from the center point to both sides. The offset of the coupler electrical head 5 is determined by reading the scale on the bubble level measuring instrument. The bubble level measuring instrument is 140mm long and has 0-70mm scale lines (resolution 1) engraved on the left and right sides from its center point.

[0034] See Figure 3 , 4 As shown:

[0035] Preferably, the measuring component 2 can be detachably mounted on the base 1 via a connecting structure, making it easy to carry;

[0036] The connecting structure includes a T-shaped groove 12 formed on the base 1 and a T-shaped boss 21 formed on one side of the measuring member 2. The T-shaped groove 12 extends from the top end of the base 1 toward the bottom end. The T-shaped groove 12 and the T-shaped boss 21 are slidably connected. The end of the T-shaped groove 12 has an end face for supporting the T-shaped boss 21.

[0037] In the above technical solution, the present invention provides a longitudinal offset detection device for the coupler electrical head of a high-speed train, and its method of use is as follows:

[0038] First, insert the T-shaped boss 21 of the measuring part 2 into the T-shaped groove 12 of the base 1, and then attract it to the metal frame of the coupler electrical head 5 by magnet. Use the scale corresponding to the center point of the bubble in the level measuring instrument 4 to determine whether the longitudinal level of the coupler electrical head 5 is within the qualified range.

[0039] This high-speed train coupler electrical head longitudinal offset detection device, consisting of a base 1 and a measuring component 2, is fixed to the coupler electrical head 5. It enables the measurement of the longitudinal offset of the coupler electrical head 5 using a level measuring instrument 4. The device features a simple structure, convenient operation, and accurate measurement. Its modular design effectively reduces storage volume and the probability of damage. Using this device, the longitudinal offset of the coupler electrical head can be quickly and accurately determined, allowing for simultaneous measurement and adjustment, reducing adjustment difficulty and improving efficiency.
