Description

At this time, the connecting hole 19 in the lower middle of the slide column 18 is connected with the water inlet and outlet of the valve body 16; thus, no matter how the wind blade 25 is blown by the strong wind, as long as the wind force exceeds the set wind force, the clean water inside the main water pipe 2 will be diverted to the inside of the telescopic water bag 20, so that the telescopic water bag 20 expands and improves the quality; and when the telescopic water bag 20 expands and improves the quality, it drives the column 8 and the top plate 7 to descend in height, so that the support arm 9 is further expanded outward; thereby reducing the height and center of gravity of the support structure, and increasing the overall quality of the support structure, thereby improving the wind resistance of the maintenance device. ;

[0037] like Figure 5 to Figure 6 As shown, a clamping plate 26 is fixedly connected to the bottom surface of the telescopic water bag 20; a magnetic ring 27 is fixedly connected to the bottom of the clamping plate 26 and the bottom of the support plate 12; the two magnetic rings 27 attract each other; during operation, when the telescopic water bag 20 is not filled with water and expanded, the magnetic ring 27 on the clamping plate 26 and the magnetic ring 27 on the support plate 12 attract each other, so that the clamping plate 26 and the support plate 12 are close to each other, and the telescopic water bag 20 is compressed; thereby reducing the volume of the telescopic water bag 20, which is convenient for the installation and transportation of the staff.

[0038] like Figures 4 to 8 As shown, a resistance ring seat 28 is bolted to the top surface of the column 8; the resistance ring seat 28 is sleeved on the outer ring of the rotating rod 22; the inner ring of the resistance ring seat 28 is evenly provided with a plurality of slots 29; a resistance insert 30 is slidably installed inside the slot 29, and the resistance insert 30 is elastic; the resistance insert 30 can be in sliding contact with the rotating rod 22; the outer ring of the resistance ring seat 28 is evenly provided with a plurality of receiving slots 31; the resistance insert 30 is slidably installed inside the receiving slot 31; A protrusion is fixed to the top of the insert 30; when working, the friction resistance of the rotating rod 22 is controlled according to the set wind force level; the resistance insert 30 stored in the storage groove 31 is pulled out, and evenly inserted into the card groove 29 of the inner circle of the resistance ring seat 28, so that the resistance insert 30 contacts the rotating rod 22, increasing the friction resistance of the rotating rod 22; thus, by adjusting the number of resistance inserts 30, the wind blade 25 can be controlled to be blown by the wind, which makes it convenient for the staff to control and adjust according to the actual situation.

[0039] like Figure 1 , Figure 2 , Figure 4 , Fig. 9 and Fig.10As shown, a bottom plate 32 is rotatably mounted on the bottom end of the support arm 9; a plurality of ball holes 33 are evenly provided on the bottom surface of the bottom plate 32; a slot 34 is provided on the side of the ball hole 33 close to the top plate 7; a ball head spur 35 is rotatably mounted inside the ball hole 33; the tip of the ball head spur 35 can be rotatably slid into the slot 34; during operation, when the support arm 9 is rotated and unfolded outward, it drives the bottom plate 32 to slide outward along the ground. At this time, the tip of the ball head spur 35 is blocked by the ground, so that the tip of the ball head spur 35 is rotated to the inside of the slot 34, reducing the influence on the rotation and unfolding of the support arm 9; when the support structure moves, at this time, the bottom plate 32 moves toward the direction of the top plate 7 along the direction of movement, so that the tip of the ball head spur 35 is inserted into the ground, increasing the friction resistance with the ground, thereby reducing the probability of displacement of the support structure.

[0040] Working principle: Use bolts to fix the square tube 1 on the supporting structure, fix the installation beam 5 to the outer ring of the square tube 1, use bolts to install the installation vertical beam 6 into the installation groove of the installation beam 5, fix the main water pipe 2 to the outside of the square tube 1, and then install the diversion pipe 3 and the nozzle 4; unfold the support arm 9 at the bottom of the column 8, so that the slider 11 slides along the slide groove 10, driving the connecting telescopic rod 13 to extend, and driving the spring 14 to stretch; rotate the rotating rod 22 in the middle of the column 8, drive the internal thread slide plate 23 to slide along the guide limit frame 21, control the internal thread slide plate 23 to move to the middle of the threaded section of the rotating rod 22, and drive The push frame 24 slides, driving the slide post 18 to slide along the slide hole 17 of the valve body 16, so that the two connecting holes 19 on the slide post 18 are respectively located above and below the water inlet and water outlet of the valve body 16, thereby cutting off the water inlet and water outlet of the valve body 16; according to the set wind force level, the friction resistance of the rotating rod 22 is controlled; the resistance plug 30 stored in the storage groove 31 is pulled out, and evenly inserted into the card groove 29 of the inner circle of the resistance ring seat 28, so that the resistance plug 30 contacts the rotating rod 22, increasing the friction resistance of the rotating rod 22; by adjusting the number of resistance plugs 30, the wind blade 25 can be controlled to be blown by the wind;

[0041] After the ground installation is completed, the maintenance device is hoisted to the top surface of the bridge pier by a crane, so that the diversion pipes 3 are distributed on the periphery of the bridge pier, and the water outlet of the nozzle 4 faces the outer wall of the bridge pier. The clean water is pumped into the main water pipe 2 by a sprinkler truck, and then diverted by multiple diversion pipes 3, and evenly sprayed on the outer wall of the bridge pier in the clean water tank nozzle 4 for maintenance;

[0042] When a strong wind exceeding the set value is generated at the top of the bridge pier, the strong wind drives the wind blade 25 to rotate; when the wind blade 25 drives the rotating rod 22 to rotate forward, it drives the internal threaded slide plate 23 to slide downward along the guide limit frame 21, and drives the pushing frame 24 and the sliding column 18 to slide downward. When the internal threaded slide plate 23 slides to the bottom of the guide limit frame 21, the internal threaded slide plate 23 is blocked by the guide limit frame 21 and stops. At this time, the upper connecting hole 19 in the sliding column 18 is connected to the water inlet and outlet of the valve body 16; when the wind blade 25 drives the rotating rod 22 to reverse, it drives the internal threaded slide plate 23 to slide upward along the guide limit frame 21, and drives the pushing frame 24 and the sliding column 18 to slide upward. When the threaded slide plate 23 slides to the top of the inner cavity 15, the internal threaded slide plate 23 is blocked and stops. At this time, the connecting hole 19 in the lower middle of the slide column 18 is connected with the water inlet and the water outlet of the valve body 16; thus, no matter how the wind blade 25 is blown by the strong wind and rotates, as long as the wind force exceeds the set wind force, the clean water inside the main water pipe 2 will be diverted to the inside of the telescopic water bag 20, so that the telescopic water bag 20 expands and improves the quality; and when the telescopic water bag 20 expands and improves the quality, it drives the column 8 and the top plate 7 to descend in height, so that the support arm 9 is further expanded outward; thereby reducing the height and center of gravity of the support structure, and increasing the overall quality of the support structure, thereby improving the wind resistance of the maintenance device;

[0043] After the maintenance of the bridge pier is completed, the connection between the sprinkler truck and the main water pipe 2 is disconnected, and the maintenance device is lifted to the ground by a crane for disassembly and recovery; thereby improving the maintenance effect of the bridge pier, reducing the phenomenon of maintenance omissions, and reducing the probability of danger to the staff.
