Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a scraping device for high-strength repair mortar. Background Art
[0002] Throughout a building's lifecycle, both old structures weathered by time and new buildings subjected to daily use inevitably encounter damage such as cracks and peeling. These seemingly minor flaws, if not repaired promptly, can gradually expand, affecting the building's overall stability and safety. High-strength repair mortar, with its superior performance and wide range of applications, has become the preferred choice for building repair.
[0003] Currently, when using high-strength repair mortar to repair building surfaces, construction workers usually need to use tools such as scrapers to evenly compact and smooth the mortar until it is level with the bottom surface. This leveling operation is not only labor-intensive, but the smoothness of the repair also largely depends on the subjective judgment of the construction workers, and the efficiency and effect of leveling cannot be guaranteed. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, the present invention provides a scraping device for high-strength repair mortar.

[0006] Furthermore, the roller is rotatably connected between the two sliders. When the two sliders move synchronously along the guide rail, the roller contacts the mortar surface and rotates relative to the sliders.
[0007] Furthermore, the leveling device also includes: guide rods, symmetrically arranged guide rods are slidably connected to the support platform, and the bottom end of the guide rods is fixedly connected to the pressure plate; a lifting frame, the top ends of the guide rods are all connected to the lifting frame; and an electric telescopic rod, an electric telescopic rod is fixedly installed on the support platform, and the top end of the electric telescopic rod is connected to the lifting frame.
[0008] Furthermore, the leveling device also includes: connecting rods, at least two connecting rods are symmetrically arranged on the scraper; rod caps, the top of the connecting rods extends through the support platform and the top of the connecting rods is provided with rod caps with a diameter larger than the rod body; and elastic elements, an elastic element connecting the rod caps and the support platform.
[0009] Furthermore, the front end of the scraper is provided with an inclined surface, and when the scraper moves forward, the mortar moves along the inclined surface to the top of the scraper.
[0010] Furthermore, the front end of the scraper has an inverted V-shaped structure, and a baffle is installed on the rear side of the scraper.
[0011] Furthermore, the scraper has at least two rows of strip-shaped holes, which are arranged alternately.
[0012] The beneficial effects are: 1. This utility model, by sequentially providing a scraper, a roller and a pressure plate, can efficiently and quickly scrape, smooth and compact the mortar repair area, thereby effectively improving the processing efficiency;
[0013] 2. This utility model has staggered strip holes on the scraper, which allow excess mortar collected above the scraper to fall through the strip holes and fill the depressions in the mortar until the depressions are filled with mortar to the same level as the bottom of the scraper. This effectively avoids mortar waste and makes the operation simpler and more convenient.
[0014] 3. This utility model, through the sliding design of the connecting rod, allows the scraper to be adjusted to a certain extent. Through the cooperation of the rod cap and the elastic element, the scraper is always subjected to downward pressure, thus maintaining good contact with the mortar surface.

DETAILED DESCRIPTION
[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0021] A high-strength repair mortar leveling device, such as Figure 1-4 As shown, it includes: positioning plates 1, which are placed on both sides of the repair mortar and are arranged in parallel; guide rails 2, each of the positioning plates 1 is equipped with a guide rail 2 with a convex rail structure, which can effectively prevent mortar from accidentally entering the guide rail groove and causing poor sliding, and is also easier to clean when the guide rail is dirty; sliders 3, each of the guide rails 2 is slidably connected to a slider 3; and a support platform 4, which is bolted to the slider 3. The support platform 4 is a T-shaped platform, which can be manually pulled. The movable slider 3 can be moved by adding a handle to the support platform 4 for easy pulling. The support platform 4 is provided with a scraper 5 for smoothing the mortar surface, a roller 6 for smoothing the mortar, and a pressure plate 8 for compacting the mortar along the direction of movement of the slider 3 on the lower side. The roller 6 is rotatably connected between the two sliders 3. When the two sliders 3 move synchronously along the guide rail 2, the roller 6 contacts the mortar surface and rotates relative to the slider 3. The pressure plate 8 rises and falls at a specific frequency to apply pressure to the mortar when it descends, pressing it to compact it.
[0022] The leveling device further includes: guide rods 7, symmetrically arranged guide rods 7 are slidably connected to the support platform 4, and the bottom end of the guide rods 7 is fixedly connected to the pressure plate 8 by welding; lifting frame 9, the top ends of the guide rods 7 are fixedly connected to the lifting frame 9, and when the lifting frame 9 moves up and down, the guide rods 7 drive the pressure plate 8 to rise and fall synchronously; electric telescopic rod 10, an electric telescopic rod 10 is fixedly installed on the support platform 4, and the top end of the electric telescopic rod 10 is connected to the lifting frame 9.
[0023] The leveling device further includes: connecting rods 11, three connecting rods 11 are symmetrically arranged on the scraper 5, the three connecting rods 11 are respectively arranged in the middle and on both sides to ensure that the scraper 5 maintains better balance; rod caps 12, the top of the connecting rods 11 extends through the support platform 4, and the top of the connecting rods 11 is provided with rod caps 12 with a diameter larger than the rod body; elastic element 13, an elastic element 13 is connected between the rod cap 12 and the support platform 4, and the elastic element 13 can be a stainless steel compression spring.
[0024] The front end of the scraper 5 is provided with an inclined surface. When the scraper 5 moves forward, the mortar moves along the inclined surface to the top of the scraper 5. The front end of the scraper 5 has an inverted V-shaped structure. A baffle 52 is installed on the rear side of the scraper 5. Two rows of strip holes 51 are opened on the scraper 5. The two rows of strip holes 51 are staggered. The holes of the two rows of strip holes 51 completely cover the length range of the scraper 5, so as to ensure that the mortar can fall smoothly to fill any depression that occurs below the scraper 5.
[0025] When high-strength repair mortar is needed to repair or restore building surfaces, first, fix the positioning plate 1 on both sides of the base surface to be repaired. Then, apply the fully mixed high-strength repair mortar to the base surface. Control the slider 3 to move along the guide rail 2 on the positioning block using manual or electric drive equipment. This allows the scraper 5, roller 6, and pressure plate 8 to pass through the mortar repair area in sequence. As the scraper 5 moves along the direction of travel, the mortar surface is uneven, with raised excess parts and recessed missing parts. When the scraper 5 passes, the raised excess mortar will move along the inclined surface at the front end of the scraper 5 to above the scraper 5. Because the scraper 5 adopts an inverted V-shaped structure, the mortar will concentrate towards the center when it moves above the scraper 5 (when filling mortar for repair, the mortar is confined to the center). In the area between the two positioning plates, mortar is more likely to adhere and accumulate on both sides (where it contacts the positioning plates) compared to the middle. When the strip hole 51 of the scraper 5 moves to the depression on the mortar surface, the excess mortar above the scraper 5 can fall along the strip hole 51 to fill the depression and initially level the mortar surface. The slider 3 continues to move forward, and the roller 6 rotates while in contact with the mortar surface, thus making the roller 6 rotate while moving forward, effectively smoothing the initially leveled mortar and making the mortar surface smoother. Subsequently, the pressure plate 8 moves to the repair area with the support platform 4, and the electric telescopic rod 10 drives the lifting frame 9 to reciprocate and lift at a fixed frequency, thereby driving the pressure plate 8 to lift and fall at fixed intervals, compacting the smoothed mortar surface and improving the leveling effect. In addition, since an elastic element 13 is provided between the rod cap 12 at the top of the connecting rod 11 and the bearing platform 4, the scraper 5 will always be subjected to downward pressure and thus maintain good contact with the mortar surface. When this scraping device is needed, the height of the scraper 5 can be adjusted appropriately in the flat area that does not need to be repaired to achieve leveling, so that the bottom surface of the scraper 5 is always flush with the leveling surface, thereby improving the applicability of the scraper 5 and ensuring its flatness effect.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
