[0019] During the use of the device, the clamping plate 1 is placed on the bridge guardrail 9 so that the two sides of the clamping plate 1 are respectively located on the two sides of the bridge guardrail 9. Then the driving motor 5 is started, and the driving motor 5 drives the screw rod 6 to rotate. During the rotation of the screw rod 6, the maintenance device 8 connected thereto is driven to move linearly along the length direction of the screw rod 6. During the movement of the maintenance device 8, the maintenance water spraying system thereon can perform water spraying maintenance on the bridge concrete guardrail below.

[0020] The maintenance device 8 includes a mounting frame 801 with a door-shaped structure, a second threaded hole 802 is provided in the middle of the upper part of the mounting frame 801, the second threaded hole 802 is matched with the screw rod 6, a guide groove 803 is provided on both sides of the second threaded hole 802, the guide groove 803 is matched with the guide slide 4, a water tank 804 is provided on the top of the mounting frame 801, and a plurality of water spray nozzles 805 are provided inside the mounting frame 801, and the water spray nozzles 805 are connected to the water tank 804 through pipes. During the installation process, the screw rod 6 is threaded into the second threaded hole 802, and the two guide slides 4 on both sides of the clamping plate 1 are respectively inserted into the two guide grooves 803. During use, the driving motor 5 drives the screw rod 6 to rotate. Since the screw rod 6 is threadedly connected to the second threaded hole 802, and the guide slide 4 is inserted into the guide groove 803, the screw rod 6 rotates and the mounting frame 801 moves along the length direction of the guide slide 4. By controlling the rotation direction of the driving motor 5, the maintenance device 8 is controlled to move on the guide slide 4 while the water nozzle 805 sprays water for maintenance. The water in the water tank 804 is sprayed from the water nozzle 805 through the pipeline to achieve water sprinkling maintenance of the bridge guardrail 9. This makes it convenient for the maintenance device 8 to maintain the bridge guardrail 9, effectively reducing the labor intensity of the staff.

[0021] The clamping plate 1 is provided with first threaded holes 101 on both sides, and an adjusting member 2 is threadedly inserted into the first threaded hole 101. The adjusting member 2 includes an adjusting stud 201 inserted into the first threaded hole 101, and the ends of the adjusting studs 201 facing each other are fixedly connected with anti-skid pads 203, and the other end of the adjusting stud 201 located outside the clamping plate 1 is fixedly connected with a hand-held portion 202. During use, the bridge guardrail 9 is placed in the door frame of the clamping plate 1, and then the hand-held portion 202 is manually rotated to make the adjusting stud 201 rotate inward, and the anti-skid pad 203 at the head end thereof abuts against the side of the bridge guardrail 9, thereby fixing the device and the bridge guardrail 9 together, improving the safety performance of the device during installation.

The inner movable tube 303 is clamped in the outer sleeve 301, and its tube body extends out of the outer sleeve 301. The end of its outer tube body is fixedly connected with a rubber pad 304. When the bridge guardrail 9 is placed inside the door frame of the clamping plate 1, the rubber pad 304 is squeezed first to compress the spring 302. After the bridge guardrail 9 is placed, the rubber pad 304 is released. Under the elastic force of the spring 302, the rubber pad 304 presses against the side of the bridge guardrail 9, which can make the device not easy to shake before the adjusting member 2 is tightened, thereby facilitating the fixing of the device and improving the safety performance of the device during installation.
