It is the main framework of railway electrification engineering, a special type of power transmission line that supplies power to electric locomotives. It consists of several parts: contact suspension, support devices, positioning devices, supports, and foundations.

[0003] In the current overhead contact line operation, violations of operating procedures cannot be detected in a timely manner, leading to safety accidents. Therefore, there is an urgent need for an intelligent identification device that allows users to detect violations in a timely manner. Utility Model Content

[0023] Please see Figure 1-4 This utility model provides a technical solution: an intelligent identification device for violations in subway overhead contact line operations, including a frame, a portable case 1, and a wireless remote controller. The frame is composed of a fixed plate 2 and two movable plates 3 on both sides. A control box 4 is installed on the lower surface of the fixed plate 2. The movable plates 3 are connected to the fixed plate 2 through a connecting mechanism. Fixed rods 5 are provided on the lower surfaces of both ends of the movable plate 3. The lower ends of the fixed rods 5 are equipped with first rollers 7 via rotating shafts 6. A drive mechanism connected to the first roller 7 is provided at the lower end of one of the fixed rods 5. An auxiliary braking mechanism is provided in the middle of the lower surface of the movable plate 3. The portable case 1 is installed on the upper surface of the fixed plate 2 by a snap fastener. A camera 9 is installed on the upper surface of the portable case 1 via a telescopic rod 8. The wireless remote controller, telescopic rod 8, and camera 9 are all placed in the storage space of the portable case 1 and can be directly taken out when in use. The wireless remote controller is wirelessly connected to the control box 4.

[0024] It is understandable that the control box 4 is electrically connected to the drive motor 13 of the drive mechanism and the electric cylinder 16 of the auxiliary braking mechanism.

[0025] The connecting mechanism includes a connecting rod 10 disposed on the side of the fixed plate 2 and an insertion hole 11 opened on the side of the movable plate 3. One end of the connecting rod 10 is placed in the insertion hole 11 and fixed by a connecting bolt 12.

[0026] The drive mechanism includes a drive motor 13, a first transmission gear 14, and a second transmission gear 15. The drive motor 13 is mounted on a mounting base at the lower end of the fixed rod 5. The first transmission gear 14 is located at the output shaft of the drive motor 13. The second transmission gear 15 is mounted on the outside of the rotating shaft 6 and meshes with the first transmission gear 14.

[0027] The auxiliary braking mechanism includes an electric cylinder 16 disposed on the lower surface of the movable plate 3 and a mounting plate disposed at the lower end of the electric cylinder 16. A friction pad 17 is disposed on the lower surface of the mounting plate.

[0028] The electric cylinder 16 is located between the two fixed rods 5, and the electric cylinder 16 and the two first rollers 7 are on the same vertical plane.

[0029] The portable case 1 is detachably connected to the upper surface of the fixing plate 2 by a buckle. One end of the portable case 1 is equipped with a second roller, and the other end of the portable case 1 is equipped with a telescopic pull rod. The interior of the portable case 1 has a storage space. A storage battery is installed on the lower inner side of the portable case 1. The storage battery is connected to the control box 4 by a wire.
