[0016] The present invention provides a prefabricated box beam maintenance device through improvement, which has the following improvements and advantages compared with the prior art:

[0017] First, the present invention uses a lifting device to lift the beam body to the top of the maintenance plate, and then a number of hydraulic jacks drive the maintenance plate to slide downward a certain distance in the maintenance box. At this time, the bottom surface of the beam body is located in the maintenance box. At the same time, the maintenance plate uses two extrusion columns to drive the extrusion plate to slide downward a certain distance in the bottom box. The extrusion plate sprays the water in the bottom box to the bottom surface of the beam body through the water spray pipe and the first nozzle, and the water flows along the beam body to the top of the maintenance plate. Then the maintenance mechanism works to spray water on the top and side surfaces of the beam body. The water from the water spraying operation flows along the beam body to the top of the maintenance plate. The rising water level will overflow the maintenance box. The overflowed water flows into the recovery box through the bottom box for recovery. After the water spraying operation is completed, the maintenance mechanism is reset, and then the lifting equipment Continue to work and hoist the beam upward for a certain distance to leave a certain gap between the bottom surface of the beam and the top of the curing plate. At this time, the water gathered on the curing plate will fully moisten the bottom surface of the beam. After the moistening is completed, the hoisting equipment will continue to hoist the beam upward to beyond the curing box to facilitate the contact between the water on the bottom surface of the beam and the air. It is also convenient for several hydraulic jacks to drive the curing plate to slide upward and reset in the curing box. While the curing plate slides upward and resets, the water supply pump works, and the connecting pipe is connected to the water source. The water is pressurized and injected into the bottom box through the connecting pipe and the water supply pipe to ensure that there is sufficient water in the bottom box when the curing plate slides downward next time to inject into the water spray pipe, so as to achieve the maintenance of the top, side and bottom surfaces of the beam, and the maintenance effect is good.

[0018] Second, the present invention drives the travel gear, the driving gear and the linkage gear to rotate through the travel motor. The travel gear drives the travel frame to slide on the two guide rails using the travel rack, so that the first spray component and the second spray component can move along the length direction of the beam body to fully spray the top and side surfaces of the beam body.

[0019] Third: When the mobile platform of the present invention moves back and forth horizontally, the mobile platform uses one of the mobile brackets to drive the swing frame to move back and forth horizontally synchronously. Since the swing gear is engaged with the swing rack, the swing gear rotates, and the swing gear drives the mounting shaft and the mounting rod to rotate. The mounting rod drives the slider to slide back and forth on the swing rod for a certain distance. At the same time, the slider drives the swing rod to swing back and forth at a certain angle, thereby increasing the spraying range of the second nozzle. When the width span of the beam body is too large, the second nozzle can also fully spray the top surface of the beam body.

[0020] Fourthly, the active bevel gear of the present invention drives the adjusting part to work, and the adjusting part drives the adjusting block and the adjusting rack to move back and forth horizontally for a certain distance. The adjusting rack uses the fan gear to drive the adjusting handle to swing back and forth at a certain angle, and then the second spray box and several third nozzles can swing back and forth at a certain angle, so that the third nozzle can spray the side of the beam body comprehensively.

[0021] Fifth, the active bevel gear of the present invention drives the second bevel gear to rotate, the second bevel gear drives the second linkage shaft and the second cam to rotate, the second cam drives the lifting block and the lifting frame to move back and forth a certain distance by using the second roller, the lifting frame moves back and forth on the two vertical rods, the lifting frame drives the piston to move back and forth in the water replenishment tank by using the push rod, when the piston moves upward, the piston draws the water in the water replenishment tank into the first spray box and the second spray box through the first hose and the second hose, so as to achieve continuous water supply operation for the first spray box and the second spray box, when the piston moves downward, the piston draws the water in the water tank into the water replenishment tank through the third hose.
