Beneficial Effects
[0012] The utility model provides an automatic maintenance device for bridge piers. Compared with the prior art, it has the following beneficial effects:
[0013] 1. The automatic maintenance device for the bridge pier body is provided with a base and a support mechanism, and the hydraulic rod is started to adjust the angle of the support mechanism, and the second motor is directly started. The second motor drives the screw to rotate, and the screw rotation causes the movable rod to move. After the movable block is moved out of the pier, the second motor is turned off, and then the steel pipe is fixed on the movable block through the clamping strip, and then the hydraulic rod is retracted to make the movable block drop, and then the second motor is started to reverse, so that the movable block approaches the pier, and then the first motor is started, and the first motor drives the rotating plate and the support mechanism to rotate, and the support mechanism drives the fixed frame, the movable block and the steel pipe to rotate, and the maintenance water is sprayed from the nozzle to replenish the pier with water to prevent it from drying and cracking.
[0014] 2. The automatic maintenance device for the bridge pier body is equipped with an inclination sensor, an infrared rangefinder and a PLC. The second motor is started. After the moving rod moves the movable block out of the pier and descends, the infrared rangefinder and the inclination sensor are started. The inclination sensor senses the angle between the movable block and the steel pipe. If it is not vertical, a signal is sent to the PLC. The PLC starts the third motor. The third motor rotates the movable block to adjust the angle between the movable block and the steel pipe to make it vertical. Because the pier is not a perfect circle, the infrared rangefinder senses the distance between the movable block and the pier. When the movable block is too close to or too far away from the pier, the infrared rangefinder sends a signal to the PLC. The PLC starts the second motor to rotate the second motor forward and reverse. The second motor rotates the screw forward and reverse. In this way, the distance between the movable block and the pier can be adjusted, so that the movable block automatically maintains a distance from the outer wall of the pier.
