[0002] With the rapid development of my country's economy, the total mileage of highways is also constantly increasing, especially in mountainous areas. In order to ensure local economic development, highways need to be built. In mountainous areas and across rivers, bridges need to be built for every kilometer. Most of the current bridges use steel frame structures, which are not only light in weight but also have high structural strength compared to concrete reinforced structures. However, the surface of the steel frame structure needs to be treated with anti-corrosion. In the early stage of construction, the surface of the steel frame has been sprayed with paint, but after a long period of weathering and corrosion, the paint on some parts of the steel frame surface will fall off. In order to ensure that the steel frame will not be corroded, the paint that has fallen off needs to be repainted.

The first rotating block 113 and the second rotating block 114 are provided with a first triangular limiting groove 1131 and a second triangular limiting groove 1141 of the same shape, and the first triangular limiting groove 1131 and the second triangular limiting groove 1141 are respectively provided with two first friction columns 116 and two second friction columns 117 which are symmetrically arranged, and the opposite back surfaces of the two first friction columns 116 are magnetically contacted and cooperated with the linkage toggle rods 115, and the opposite back surfaces of the two second friction columns 117 are also magnetically contacted and cooperated with the two linkage toggle rods 115, and all the linkage toggle rods 115 are fixed on the linkage toggle rod mounting plate 141.

[0027] The working principle of the bridge support surface spraying equipment disclosed in the present invention is as follows: paint is injected into the storage ball 101 through the injection port 1012, so that the interior of the storage ball 101 is filled with paint, and the set separating conical plate 118 and the slowing baffle 119 can reduce the amplitude of the paint shaking in the storage ball 101, so that the wave amplitude of the paint surface when shaking is reduced, thereby reducing the impact on the posture of the rotor drone 2. During spraying, the boost motor 105 is controlled, and the output disk of the boost motor 105 drives the active friction sleeve 112 to rotate. The active friction sleeve 112 drives the first friction column 116 to slide in the first triangular limiting groove 1131 through friction force (referring to the movement trend). It should be noted that the first triangular limiting groove 1131 and the second triangular limiting groove 1141 have the same structure, and both have a triangular groove composed of two inclined surfaces and an arc surface. The triangle is isosceles and the bottom side is an arc. The first friction column 116 slides on the hypotenuse of the triangle, and the hypotenuse is symmetrically arranged. Therefore, there will be a first friction column 116 that is subjected to the friction force of the active friction sleeve 112. Move toward the angle between the hypotenuse and the arc side, that is, move in the direction of decreasing space, so that the pressure of the active friction sleeve 112 and the hypotenuse of the triangle on the first friction column 116 increases. The friction force will increase as the pressure increases, which will cause the first rotating block 113, the active friction sleeve 112 and the first friction column 116 to be stuck together in turn. The first rotating block 113 and the first friction column 116 rotate under the drive of the active friction sleeve 112, which will cause the linkage toggle rod 115 to rotate. The rotation of the linkage toggle rod 115 will drive the second rotating block 114 to rotate. The rotation of the second rotating block 114 will drive the input end of the air pump 110 to rotate. At this time, the air pump 110 will provide positive pressure to the storage ball 101.

[0028] Under actual working conditions, in order to improve the endurance of the rotor UAV 2, the weight of the booster motor 105 is often very small, that is, the power is very low. In order to drive the air pump 110, the booster motor 105 may be damaged. In order to prevent this phenomenon, during the flight of the rotor UAV 2, the lower side of the propeller of the rotor UAV 2 (not directly below, otherwise it will affect the flight attitude of the rotor UAV 2) is used. If there is still a small amount of paint left inside the storage ball 101, the overall weight is low at this time, which can make the driven impeller 109 move to the bottom of the propeller. At this time, the flight control inside the rotor UAV 2 The overall flight attitude is coordinated and the rotation speeds of the four motors are controlled. Since the driven impeller 109 is not directly below the propeller of the air pump bracket 102, and the surrounding airflow is used to drive the driven impeller 109, for example, the position between the two propellers, the flight attitude of the rotor UAV 2 is not seriously affected. The position of the driven impeller 109 can be adjusted by controlling the telescopic adjustment of the telescopic rod of the electric cylinder 107. The airflow drives the driven impeller 109 to rotate. The driven impeller 109 drives the auxiliary friction sleeve 111 to rotate through the transmission belt 108. The rotation of the auxiliary friction sleeve 111 will pass through the friction force and the second friction column 11 7 drives the second rotating block 114 to rotate (the principle is the same as the first rotating block 113 and the first friction column 116). The rotation of the second rotating block 114 will drive the input end of the air pump 110 to rotate, and when the second rotating block 114 rotates, it will drive the linkage toggle rod 115 to rotate. There are two linkage toggle rods 115, so one linkage toggle rod 115 will drive one of the first friction columns 116 to move in the direction of the triangle space becoming larger (the other first friction column 116 will also move in the direction of the triangle space becoming larger under the action of the friction force of the active friction sleeve 112). When the boost motor 105 is started, the power will not be transmitted to the auxiliary friction sleeve 111 (it should be noted that there is a movement gap between the linkage toggle rod 115 and the triangular inclined surfaces of the first triangular limiting groove 1131 and the second triangular limiting groove 1141. The purpose of the gap is to toggle the first friction column 116 and the second friction column 117 to move so that they are no longer subjected to the squeezing force).

[0029] The increase in the internal pressure of the storage ball 101 will squeeze the paint into the telescopic pipe 124, and then enter the sliding pipe 136 through the hose 125 (a solenoid valve is arranged inside the sliding pipe 136 to control the on and off of the paint). The sliding pipe 136 sends the paint into the space between the atomizing spray plate 134 and the spring limiting plate 131, so that the pressure in the internal space increases. At this time, the piston plate 138 squeezes the spring 137, so that the piston plate 138 moves toward the direction of the spring limiting plate 131 (a through hole is provided on the spring limiting plate 131). The movement of the piston plate 138 will drive the blocking rod 139 to be drawn out from the tapered through hole of the atomizing spray plate 134, and the paint will be sprayed out through the tapered through hole of the atomizing spray plate 134. At this time, the paint is sprayed on the bridge in atomized form. When the electromagnetic valve inside the sliding tube 136 is closed, the blocking rod 139 is pushed back into the tapered through hole of the atomizing spray plate 134 under the action of the spring 137 to seal it and prevent the paint inside from oxidizing. The limiting column 140 can limit the distance between the atomizing spray plate 134 and the piston plate 138. According to the shape and size of the actual bridge, the support sliding arm 123 and the telescopic pipe 124 of appropriate length are selected, the support sliding arm 123 is fixed to the hose 125, and then the positioning electromagnet 122 is started to fix the support sliding arm bracket 121 and the support sliding arm 123 together. The user can also control the swing amplitude of the two servos 128 to drive the pull rod connecting seat 130 to move through the swing arm and the pull rod 129 of the servo 128. The movement of the pull rod connecting seat 130 will drive the spray chamber 132 to adjust the swing of the activity center of the ball seat 127 and the movable ball 135. At this time, the direction of the paint sprayed by the atomizing spray plate 134 will change.
