DETAILED DESCRIPTION
[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0032] See also Figure 1 A concrete crack grouting repair device in this embodiment includes a grouting repair device body 1, a filling head 2 is fixedly installed at the center of the bottom end of the grouting repair device body 1, a repair mechanism 3 is provided on the grouting repair device body 1, and two baffles 4 are provided on the repair mechanism 3.
[0033] It should be noted that the grouting repair device body 1 is a prior art. For details, reference may be made to a concrete crack grouting repair device disclosed in Chinese Patent Publication No. CN213539804U. Therefore, its specific working principle will not be described in detail in this technical solution.
[0034] See also Figure 1-4 The repair mechanism 3 includes a scraping component arranged on the grouting repair device body 1 and a cleaning component arranged on the scraping component.
[0035] Among them, the front and rear sides of the bottom surface of the baffle 4 are both provided with fixing grooves 5, and the inner wall of the fixing groove 5 is rotatably connected with a moving wheel 6 to improve the convenience of moving the device.
[0036] At the same time, the scraping assembly includes a box body 301 fixed on the left and right sides of the grouting repair device body 1, a fixed rod 302 fixed on the back between the inner top wall and the inner bottom wall of the box body 301, a support spring 303 movably mounted on the top of the outer surface of the fixed rod 302, a movable plate 304 slidably connected to the middle position of the outer surface of the fixed rod 302, a connecting rod 305 fixed on the opposite side of the bottom surface of the two movable plates 304, and a scraper 306 fixed at the bottom end of the two connecting rods 305. The scraping assembly can scrape the repair material flat and scrape off excess repair material during the movement of the device.
[0037] At the same time, the two baffles 4 are respectively fixed on the opposite sides of the bottom surfaces of the two boxes 301, and the two ends of the support spring 303 are respectively abutted between the top surface of the movable plate 304 and the inner top wall of the box 301. The elastic potential energy of the support spring 303 can act in the opposite direction on the movable plate 304, which is conducive to making the scraper 306 fit closely with the ground.
[0038] In addition, a fixing hole is provided on the top surface of the movable plate 304 at one side away from the connecting rod 305 , and the fixing rod 302 passes through the fixing hole and is slidably connected thereto. The fixing rod 302 can support and limit the movable plate 304 .
[0039] In addition, a clearance hole is opened on one side of the back of the bottom of the box body 301 close to the scraper 306, and the connecting rod 305 passes through the clearance hole and extends to the bottom of the box body 301, so as to facilitate the scraping of the repair material by the scraper 306.
[0040] It should be noted that the cleaning component includes a collection box 307 fixed on the back between the opposite sides of the two boxes 301, three delivery pipes 308 fixed on the bottom of the front of the collection box 307, a guide pipe 309 fixed on the front of the bottom end of the three delivery pipes 308, a plurality of suction heads 310 fixed on the bottom surface of the guide pipe 309 and evenly distributed from left to right, and an exhaust fan 311 fixedly installed on the top of the back of the collection box 307. The cleaning component can uniformly collect the excess repair materials scraped off by the scraping component to avoid excess repair materials remaining on the ground, thereby reducing the difficulty of subsequent cleaning.
[0041] Finally, the conveying pipe 308 is located between the scraper 306 and the filling head 2, and a box door 312 is hinged on the top surface of the collection box 307. The box door 312 can be opened to take out the repair material collected in the collection box 307.
[0042] The working principle of the above embodiment is:
[0043] When in use, the grouting repair device body 1 is moved to the specified position, and the filling head 2 is aimed at the crack to be repaired, and then the device is pressed down to make the scraper 306 fit closely with the ground. During the pressing process, the scraper 306 pushes the movable plate 304 upward through the connecting rod 305 and squeezes the supporting spring 303 upward. At this time, the supporting spring 303 has elastic potential energy and acts in the opposite direction on the movable plate 304, so that the scraper 306 can be closely attached to the ground. Then the grouting repair device body 1 is operated to inject concrete into the crack through the filling head 2 for repair treatment. The device can be moved while injecting along the crack. During the movement, the scraper 306 can scrape the repair material flat and scrape off the excess repair material. At the same time, the exhaust fan 311 is started and the exhaust fan 311 works to make the excess repair material enter the guide pipe 309 through the suction head 310 and finally be collected into the collection box 307 through the conveying pipe 308 for unified collection, which is more convenient to use.
