DETAILED DESCRIPTION

[0016] like Figures 1 to 3 As shown, a box girder spray maintenance device includes a gantry, both ends of which are fixedly connected to a walking beam 3, the walking beam 3 is arranged on a track 15, the gantry includes a spray pipe 6, a plurality of nozzles 63 are installed on the spray pipe 6, a support plate 2 is fixedly connected to the walking beam 3 on one side of the gantry, a water tank 1 is arranged on the support plate 2, a water pump 12 is arranged in the water tank 1, and the water pump 12 is connected to the spray pipe 6 through a hose 11.

[0017] A wire take-up device 4 and a power distribution cabinet 5 are installed on a walking beam 3 where no water tank 1 is provided. The wire take-up device 4 and the reduction motor 32 in the walking beam 3 are electrically connected to the power distribution box. The wire take-up device 4 is used to reel in the cable with the vehicle to prevent the cable from being twisted and entangled and being pressed by the walking beam 3.

[0018] When the walking beam 3 in the device moves on the track 15, it moves outside the box beam with the spray pipe 6. During the movement, water in the water tank 1 is pumped by the water pump 12 and enters the spray pipe 6, and then sprayed toward the box beam from the nozzle 63, so as to perform comprehensive spray maintenance on the box beam.

[0019] It also includes an automatic water-adding device, which includes a controller, a water-adding pipe 9 and support rods 65 fixed on the ground at both ends of the track 15. The first travel switch 13 and the second travel switch 14 are respectively installed on the two support rods 65. The first travel switch 13 and the second travel switch 14 are triggered at both ends of the walking beam 3. The pipe mouth of one end of the water-adding pipe 9 is located above the water tank 1, and the other end of the water-adding pipe 9 is connected to the tap water pipe. A solenoid valve 10 is installed on the water-adding pipe 9. The first travel switch 13 and the second travel switch 14 are connected to the controller input end, and the walking beam 3, the solenoid valve 10 and the water pump 12 are connected to the controller output end. The controller is a PLC controller, and the controller is arranged in the power distribution cabinet 5; the first travel switch 13 and the second travel switch 14 are 31 meters apart, the length of the box beam is 30 meters, and the box beam to be sprayed and maintained is located between the first travel switch 13 and the second travel switch 14.

[0020] A liquid level switch 8 is provided in the water tank 1 and is connected to an input terminal of the controller.

[0021] The working process of the automatic water adding device is:

[0022] Initially, the walking beam 3 is located at the position of the first stroke switch 13. After the box girder enters the spraying maintenance section, the controller controls the walking beam 3 to move toward the second stroke switch 14. At the same time, the water pump 12 is controlled to start, so that the maintenance device can spray the box girder while walking. After the walking beam 3 moves to the second stroke switch 14, the controller controls the walking beam 3 to move toward the first stroke switch 13. After the maintenance device returns to the first stroke switch 13, the controller controls the water pump 12 to stop and controls the solenoid valve 10 to open. Tap water flows into the water tank 1 through the water filling pipe 9. When the water in the water tank 1 triggers the liquid level switch 8, the controller controls the solenoid valve 10 to close, completing the automatic water filling of the water tank 1 and the spraying maintenance of the box girder.

[0023] The spray pipe 6 includes a top pipe 62 arranged above the box beam, and the two ends of the top pipe 62 are respectively connected to the U-shaped curved pipes 61 arranged on both sides of the box beam. The shapes of the U-shaped curved pipes 61 on both sides correspond to the shapes of the two sides of the box beam, so that the spray distances of each nozzle 63 can be the same, making the box beam spray more uniform.

[0024] The gantry also includes a support rod 65 of the same shape as the spray pipe 6, the two ends of the support rod 65 are respectively fixedly connected to the two walking beams 3, and the support rod 65 is fixedly connected to the spray pipe 6 through a plurality of connecting rods 64. This structure can be used to improve the strength of the spray pipe 6.

[0025] A water shield 31 is installed on the walking beam frame 33, and the water shield 31 is located above the walking beam 3 reduction motor 32. The water shield 31 is used to prevent the spray water from splashing onto the reduction motor 32 and prevent the reduction motor 32 from short circuit.

The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
