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, adjusting the extension length of the extension end of the second electric push rod 13 until the second distance sensor 16 detects that the distance between the second electric push rod and the bridge floor 1 reaches a distance H2And 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 detects that the distance between the first distance sensor and the bridge floor 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.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, changes and equivalent structural changes made to the above embodiment according to the technical spirit of the present invention still fall within the protection scope of the technical solution of the present invention.
