Abstract
Description
Technical Field
[0001] The present application relates to the technical field of crack repair, and particularly to a crack repair device for the waterproof layer of a bridge deck. Background Art
[0002] Common cracks on the bridge deck include shrinkage cracks, longitudinal cracks, reticular cracks and turtle shell cracks. There are many reasons for the occurrence of cracks. For example: defects in design theory or a large difference between assumptions and actual conditions, construction not carried out in accordance with design regulations and construction specifications, improper construction procedures and methods, natural factor influences, etc. After cracks appear, a repair device is needed.
[0003] In the patent with the published authorization announcement number CN218932919U, the bridge deck crack repair device includes a base, a cleaning component and a rolling component. A through groove is formed through the top of the base, and an adjustment frame is arranged in the through groove. A second sliding rod is fixedly connected in the adjustment frame, and an adjustment block is slidably connected to the second sliding rod. A first air cylinder is fixedly installed on the top of the adjustment block. The piston rod head of the first air cylinder penetrates below the adjustment block and is fixedly connected with a lifting plate. The bottom of the lifting plate is fixedly connected with an adjustment rod and a liquid discharge pipe head. The cleaning component is arranged on the right side of the top of the base, and the rolling component is arranged on the left side of the bottom of the base. The beneficial effect of the present utility model is that the provided cleaning component is convenient for blowing away the dust inside the crack while repairing, avoiding the cleaning work before repair. The provided rolling component can compact the repair liquid in the crack, thereby reducing the number of air bubbles formed in the repair liquid and improving the repair quality of the repair liquid.
[0004] When the above device is implemented, it is not convenient to perform air drying operation on the repair liquid filled in the crack. Therefore, it needs to rely on the natural air flow for drying, which will affect its drying efficiency, prolong the maintenance period of the bridge deck, and is not conducive to popularization and use. Moreover, the above device is not convenient for stirring the repair liquid, which will cause it to be in a static state for a long time and is easy to solidify. Summary of the Utility Model

[0020] By adopting the above technical solution, it can be ensured that the stirring blade does not interfere with the hose during rotation, thus ensuring the service life of the hose.
[0021] Advantages of this application:
[0022] 1. For this bridge deck waterproof layer crack repair device, the driving motor drives the rotating rod, the second transmission wheel and the fan to rotate, and at the same time pushes the device to move, thus moving the fan above the filled waterproof layer repair agent, enabling it to perform a drying operation, improving the drying efficiency, accelerating the maintenance period of the bridge deck. At the same time, the rotating force can be transmitted to the first transmission wheel and the stirring rod through the transmission belt, and then the stirring rod can drive the stirring blade to rotate, stirring the repair agent in the inner cavity of the tank to prevent it from solidifying due to being in a static state.
[0023] 2. The bridge deck waterproof layer crack repair device drives the screw rod to rotate through the driving motor, thereby driving the slider and the hard pipe to move downward until the injection pipe is inserted into the deepest part of the crack.
