[0019] Embodiment:

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0021] A maintenance device for large-span bridge piers in cold regions, comprising a maintenance mechanism 1, a climbing mechanism 3, a water supply mechanism and a bridge pier. The climbing mechanism adjusts the height of the maintenance mechanism through a motor and a lifting cable to meet the needs of different maintenance heights. The pulley mechanism is connected to the maintenance mechanism surrounding the bridge pier and is used for water supply maintenance and temperature maintenance of the bridge pier. Reserved guide rails 2 are provided on both the left and right side walls of the bridge pier. Guide rail clamping members are arranged inside the reserved guide rails 2. There are several guide rail clamping members, and several guide rail clamping members are respectively hinged on several reserved guide rails 2. The guide rail clamping members cooperate with the clamping grooves for clamping and fixing the climbing rails. The maintenance mechanism 1 is slidably connected to the reserved guide rails 2. The maintenance mechanism includes a heating area 16 and a spraying area. The heating area 16 completes heating the maintenance surface of the bridge pier through heating wires 19, and the spraying area performs spraying work through a rotating nozzle 9. Temperature sensors 12 and humidity sensors 13 are provided near the bridge pier in the whole system; when the temperature drops to a certain extent, the intelligent maintenance system starts to work, and the surface temperature of the bridge pier is maintained through the heating area 16. Similarly, when the temperature drops to a certain extent, the spraying area starts to work to maintain the humidity of the bridge pier maintenance. Through the above technical solution, the problem that the bridge pier maintenance in cold regions freezes and the bridge pier maintenance is not in place is solved. At the same time, the system has an automatic monitoring ability, improving the maintenance efficiency. The climbing mechanism 3 includes a motor 6, a lifting cable 4 and a guide wheel; the maintenance mechanism 1 and the water supply mechanism are connected through a water pipe 5. The upper end of the water pipe 5 extends into the interior of the maintenance mechanism 1. The lower end of the water pipe 5 is connected to a water tank 7. The side wall of the water pipe is provided with uniformly arranged rotating nozzles 9 to ensure full coverage of the bridge pier surface. Temperature sensors 12 and humidity sensors 13 are provided on the surface of the bridge pier. The temperature sensors 12 and humidity sensors 13 are on the surface layer of the bridge pier and transmit the monitoring data to the control room 11. There is a computer 10 in the control room 11 to analyze and judge whether the temperature and humidity are suitable for maintenance. The interior of the maintenance mechanism 1 is provided with a control room 11, a heating area 16 and a computer 10. The heating area 16 is to timely increase the temperature to prevent icing. To ensure the overall stability of the system, a heating area 16 is provided in the maintenance mechanism 1. The lower side wall of the maintenance mechanism 1 is provided with a rubber pad 18 through mounting expansion screws 17.

[0022] The maintenance mechanism 1 includes an EPS board 15 and an aluminum alloy protection board 14. The EPS has a heat preservation effect. The EPS board 15 is arranged on the inner layer, and the aluminum alloy protection board 14 is arranged on the outer layer, which can reduce the overall weight and make the whole system easy to control and safe.

[0023] The computer 10 is electrically connected to the heating area 16, the temperature sensor 12 and the humidity sensor 13 through wires. A coil protection box 8 is arranged outside the wires.

[0024] The heating zone 16 includes a heat preservation partition plate 21. Inside the heat preservation partition plate 21, a heating wire 19 is fixedly arranged through bolts 20. The heating wire 19 is separated and heat-insulated from other components by the heat preservation partition plate 21 to ensure the overall safety and the effectiveness of heat preservation.

[0025] The guide wheel is rotatably connected to the side wall of the bridge pier. A lifting cable 4 is arranged outside the guide wheel. One end of the lifting cable 4 is fixedly connected to the upper side wall of the maintenance mechanism 1, and the other end of the lifting cable 4 is fixedly connected to the output shaft of the motor 6.

[0026] Working principle:

[0027] During maintenance, first starting from the bottom of the bridge pier, the maintenance mechanism 1 starts to supply water for maintaining the bridge pier through the spraying device, and the rotary nozzle 9 sprays the bridge pier surface in all directions. Among them, the temperature sensor 12 and the humidity sensor 13 monitor the state of the bridge pier at any time. When the computer 10 in the control room 11 receives the information that the moisture on the pier surface is insufficient, the control room 11 will feedback it to the water pump in the water tank 7 (the water pump is not drawn in this application), and this process is repeated 3 - 5 times; the temperature sensor 12 monitors the temperature of the maintenance mechanism 1 at any time. When the monitored temperature is lower than 20 °C, the computer 10 in the control room 11 issues an instruction again to drive the operation of the heating wire 19 in the heating zone 16 to increase the system temperature and ensure a good maintenance process.

[0028] After experiencing a maintenance cycle, the control room 11 will control the climbing mechanism 3 to rise. Among them, the guide wheel and the lifting cable 4 lift the maintenance mechanism 1 through the motor 6 and will move upward on the reserved guide rail 2 to start the maintenance work, which is adjacent to the first maintenance position to ensure reliable maintenance quality.
