A method for spraying a deck waterproofing material as shown in fig. 3, 4 and 6, comprising the steps of:

step one, determining the distance between the first nozzle and the bridge floor, and simultaneously determining the distance between the second nozzle and the bridge floor:

according to the formulaDetermining the distance H between the first nozzles 11 and the deck 1₁(ii) a Wherein L is₁The width of the bridge deck 1 between the base plate 7 and the anti-collision wall 8, and alpha is the angle of the sector sprayed by the first nozzle 11;

dividing the bridge deck 1 between two rows of base plates 7 into n spraying channels, wherein n second nozzles 15 are correspondingly arranged on the n spraying channels, and each second nozzle 15 is positioned right above the central line of the corresponding spraying channel and is used for spraying the bridge deck according to a formulaDetermining the distance H between the second nozzles 15 and the deck 1₂(ii) a Wherein L is₂Between two rows of base plates 7The width of the bridge deck 1, beta is the angle of the spraying sector of the second nozzle 15, n is a positive even number, and the value range of n is 4-8;

in this example, H₁Has a value range of 400 mm-500 mm and H₁＝H₂，α＝β，n＝4；

Step two, judging whether the bridge deck waterproof material spraying machine is positioned on the straight-line bridge deck or not:

acquiring the distance between the first distance sensor 12 and the bridge floor 1, acquiring the distance between the second distance sensor 16 and the bridge floor 1, and determining that the bridge floor waterproof material spraying machine is positioned in a bridge floor straight line section when the first distance sensor 12 detects that the distance between the first distance sensor 12 and the bridge floor 1 is equal to the distance between the second distance sensor 16 and the bridge floor 1, and executing the step three;

when the first distance sensor 12 detects that the distance between the first distance sensor and the bridge deck 1 is not equal to the distance between the second distance sensor 16 and the bridge deck 1, determining that the bridge deck waterproof material spraying machine is located on the bridge deck of the curve section, and executing the fourth step;

step three, spraying a straight-line bridge deck waterproof material:

301, adjusting the height of the extending end of the first electric push rod 9 to make the distance between the first nozzle 11 and the bridge floor 1 reach the distance H₁；

Step 302, adjusting the height of the extending end of the second electric push rod 13 to enable the distance between the second nozzle 15 and the bridge floor 1 to reach a distance H₂；

303, controlling the traveling frame and the coating supply mechanism to operate, so that the bridge deck waterproof material spraying machine travels along the straight-line-section steel rail 20, and spraying the waterproof material on the straight-line section of the bridge deck;

step four, spraying waterproof materials on the bridge deck of the curved road section:

step 401, adjusting the extension length of the extension end of the first electric push rod 9 until the first distance sensor 12 detects that the distance between the first electric push rod and the bridge deck 1 reaches a distance H₁And maintaining the distance between the first distance sensor 12 and the deck 1 at a distance H₁；

Step 402, adjustThe extension length of the extending end of the second electric push rod 13 is not less than the distance H between the second distance sensor 16 and the bridge floor 1₂And maintaining the distance between the second distance sensor 16 and the deck 1 at a distance H₂；

It should be noted that the distance between the first distance sensor 12 and the bridge deck 1 is detected by the first distance sensor, and is the distance between the first nozzle 11 and the bridge deck 1; the second distance sensor 16 detects that the distance between the second distance sensor and the bridge floor 1 is the distance between the second nozzle 15 and the bridge floor 1 when the bridge floor is straightly cut;

and step 403, controlling the traveling frame and the coating supply mechanism to continuously operate, so that the bridge deck waterproof material spraying machine runs along the curve section steel rail 20, and spraying the waterproof material on the bridge deck 1 of the curve section.

It should be noted that, because the bending section bed plate 7 needs to be raised by a certain angle, the distance between the first nozzle 11 and the second nozzle 15 and the bridge deck 1 changes, in order to eliminate the influence of the raising angle of the bed plate 7 and ensure the normal spraying of the bridge deck 1, the heights of the first nozzle 11 and the second nozzle 15 need to be adjusted to the original height, and at this time, the influence of the raising angle of most of the bed plate 7 can be offset. Because the included angle between the nozzle and the bridge floor is changed while the heights of the first nozzle 11 and the second nozzle 15 are changed, the spraying surfaces sprayed by the first nozzle 11 and the second nozzle 15 cannot directly cover the width of the whole bridge floor like a straight line section, but the change of the included angle between the nozzle and the bridge floor is relatively small due to the flowability of the waterproof coating, so that the influence of the lifting angle of the rest base plate 7 can be offset by the flowability of the waterproof coating, and the normal spraying of the bridge floor waterproof material of the curve section is ensured.

In this embodiment, in step 401, the specific manner of determining the extending direction of the extending end of the first electric push rod 9 is as follows:

when the first distance sensor 12 detects that the distance between the first distance sensor and the bridge floor 1 is more than H₁When the distance between the first distance sensor 12 and the bridge floor 1 reaches the distance H, the controller 2 controls the first electric push rod 9 to extend until the first distance sensor detects that the distance between the first electric push rod and the bridge floor 1 reaches the distance H₁(ii) a When the first distance sensor 12 detectsThe distance between the bridge deck and the bridge deck 1 is less than H₁When the first distance sensor 12 detects that the distance between the first electric push rod 9 and the bridge floor 1 reaches the distance H, the controller 2 controls the first electric push rod 9 to retract₁；

In step 402, the specific extending and retracting direction of the extending end of the second electric push rod 13 is determined as follows:

when the second distance sensor 16 detects that the distance between the second distance sensor and the bridge floor 1 is greater than H₂When the distance between the second distance sensor 16 and the bridge floor 1 reaches the distance H, the controller 2 controls the second electric push rod 13 to extend until the second distance sensor detects that the distance between the second electric push rod and the bridge floor 1 reaches the distance H₂(ii) a When the second distance sensor 16 detects that the distance between it and the bridge deck 1 is less than H₂When the distance between the second distance sensor 16 and the bridge floor 1 reaches the distance H, the controller 2 controls the second electric push rod 13 to retract until the second distance sensor detects that the distance between the second electric push rod and the bridge floor 1 reaches the distance H₂。

When the extending end of the first electric push rod 9 retracts, the extending end of the second electric push rod 13 extends; when the extending end of the first electric push rod 9 extends, the extending end of the second electric push rod 13 retracts.
