Claims

1. A de-icing device for subway overhead contact lines, characterized in that, Includes a roller control panel, housing, elevator, control cabinet, and power supply cabinet, among which: The roller control panel is installed on the top of the housing, and the control cabinet and power cabinet are both located inside the housing. The housing is used for installation on an engineering vehicle. The roller operating platform includes a platform and a first roller, a second roller, a first belt, a second belt, and a stepper motor mounted on the platform. The outer surface of the first roller is provided with a plurality of first cylindrical bodies. The first roller includes a first flat pulley. The outer surface of the second roller is provided with a plurality of second cylindrical bodies. Both the first cylindrical bodies and the second cylindrical bodies are used to contact the contact wire. The second roller includes a second flat pulley. One end of the first belt is sleeved and mounted on the first flat pulley, and the other end of the first belt is sleeved and mounted on the second flat pulley. The stepper motor includes a motor pulley. One end of the second belt is sleeved and mounted on the motor pulley, and the other end of the second belt is sleeved and mounted on the second flat pulley. When the stepper motor rotates, it drives the second roller and the first roller to rotate, thereby rotating and striking the ice on the contact wire. The lifting platform includes a lead screw, a meshing worm gear and worm, a motor gearbox, and a base. The motor gearbox is mounted on the base and includes a servo motor and a motor shaft. The motor shaft is mounted on the worm. The lead screw includes a mounting end and a telescopic end. The worm gear is sleeved on the outer wall of the telescopic end and helically engages with the lead screw. The mounting end is mounted inside the housing, and the end face of the telescopic end is mounted on the platform. When the servo motor rotates, the lead screw drives the roller operating platform to rise and fall. The control cabinet is communicatively connected to the stepper motor and the servo motor, and the power supply cabinet is electrically connected to the control cabinet.

2. The subway contact network de-icing device according to claim 1, characterized in that, The diameters of the first planar pulley, the second planar pulley, and the motor pulley increase sequentially.

3. The subway contact network de-icing device according to claim 1, characterized in that, The elevator also includes an upper flange and a lower flange. The upper flange is installed on the end face of the telescopic end, and the lower flange is installed on the end face of the mounting end. The top of the housing is provided with an opening for the elevator to pass through. The upper flange is threadedly installed on the bottom surface of the platform, and the lower flange is threadedly installed on the bottom of the housing.

4. The subway contact network de-icing device according to claim 1, characterized in that, The control cabinet includes a power button, a start button, a stepper motor speed adjustment button, an up button, a down button, and a display screen. The outer side of the cabinet is provided with slots, and the power button, the start button, the stepper motor speed adjustment button, the up button, the down button, and the display screen are all installed in the slots.
