Description

Technical Field

[0001] This utility model relates to the field of crack repair technology, specifically to a concrete crack repair grouting mechanism. Background Technology

[0002] Concrete grouting is a technique that uses pressure to inject repair materials into cracks or pores in a concrete structure. Grouting materials typically include polymers, epoxy resins, etc. After injection, these materials diffuse and penetrate within the cracks, bonding tightly with the concrete matrix to form a water-insoluble solid, thereby achieving the purpose of sealing leaks, stopping water leakage, and repairing cracks.

[0003] According to announcement number CN221810753U, a concrete crack repair grouting mechanism is disclosed, including a base. A handle is fixedly connected to the top right side of the base, and casters are rotatably connected to both the left and right sides of the bottom of the base. An adjustment structure is provided on the upper left side of the base, and a cleaning structure is provided on the upper right side of the base. The adjustment structure includes an electric telescopic rod, the top of which is fixedly connected to the base. The output end of the electric telescopic rod faces downwards, and a connecting plate is fixedly connected to the output end. This concrete crack repair grouting mechanism can accelerate the discharge efficiency of the discharge pipe by driving a motor to rotate a mixing frame. This allows the grouting pipe to be adjusted according to the crack depth. When the bidirectional threaded rod rotates, it can drive the sleeve to move. At this time, the bottom of the sleeve can drive a scraper via an extension rod to scrape and clean the concrete adhering to the outside of the sleeve.

[0004] However, the aforementioned concrete crack repair grouting mechanism has the following drawbacks:

[0005] Because there is no agitation and scraping mechanism inside the concrete hopper, although the material can be agitated, prolonged storage inside will cause the material to adhere to the inner wall and bottom of the hopper, making it inconvenient to clean and affecting future use. It also makes it difficult to adjust grouting for cracks in different locations, and the varying grouting depths make it difficult to observe the grouting process, thus affecting grouting efficiency.

[0006] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0007] In view of the problems in the related technologies, this utility model proposes a concrete crack repair grouting mechanism to overcome the above-mentioned technical problems existing in the existing related technologies.

[0008] Therefore, the specific technical solution adopted by this utility model is as follows:

[0009] A concrete crack repair grouting mechanism includes a trolley, a stirring and scraping mechanism, a grouting device, and a position adjustment mechanism. The trolley has a base plate at its bottom, and a grouting tank is located on one side above the base plate. The top of the grouting tank is equipped with a stirring and scraping mechanism for stirring the grout and preventing it from sticking to the wall. The top of the grouting tank has a feed inlet, and the bottom of the grouting tank is connected to the grouting device. A position adjustment mechanism for adjusting the grouting position is fixed on the other side above the base plate.

[0010] As a further embodiment of this utility model, the stirring and scraping mechanism includes a stirring motor, which is fixed above the grouting tank, and the output end of the stirring motor is fixed with stirring blades via a connecting rod.

[0011] As a further embodiment of this utility model, a bottom scraper is fixed to the bottom of the connecting rod, and a side wall scraper is fixed to one end of the stirring blade.

[0012] As a further embodiment of this utility model, the grouting device includes a pump body, one end of which is connected to the grouting tank via a pipe, and the other end of which is connected to a telescopic hose, one end of which is connected to a grouting head.

[0013] As a further embodiment of this utility model, the position adjustment mechanism includes a horizontal electric slide rail, a vertical electric slide rail fixed to the horizontal electric slide rail by a first slider, a U-shaped frame fixed to the vertical electric slide rail by a second slider, a rotating motor fixed to the U-shaped frame, and an electric telescopic rod fixed to the output end of the rotating motor.

[0014] As a further embodiment of this utility model, the grouting head is fixedly connected to one end of the electric telescopic rod, and a camera is fixedly mounted on the grouting head.

[0015] The beneficial effects of this utility model are as follows: by setting up a stirring and scraping mechanism, the grout inside the grouting tank can be stirred while scraping the inner wall and bottom of the grouting tank, preventing the grout from adhering to the inner wall and bottom of the grouting tank after prolonged storage, making it easier for people to clean.
