Technical Field

[0001] The utility model relates to the technical field of tunnel construction concrete mortar scraping, in particular to a simple scraper for construction. Background Art

[0002] During tunnel construction, in order to improve the structural strength of the tunnel inner wall, it is often necessary to spray concrete mortar onto the tunnel inner wall through a concrete mortar wet spraying machine. However, after spraying the concrete mortar on the tunnel inner wall, there will be uneven spraying, so the concrete mortar sprayed on the tunnel inner wall needs to be scraped and leveled.

[0003] At present, when scraping and leveling the concrete mortar sprayed on the inner wall of the tunnel, the scraping and leveling operation is mainly carried out manually by using a scraper with a handle. Although the scraping and leveling operation of the concrete mortar sprayed on the inner wall of the tunnel can be achieved by manually holding the scraper, the long-term manual scraping will make the manual labor intensity greater. At the same time, manual scraping and leveling may easily lead to the concrete mortar on the inner wall of the tunnel being not continuous due to frequent breaks, and the scraping efficiency is relatively low.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] like Figure 1-Figure 3As shown, a simple scraper for construction in this embodiment includes a scraper plate 1. The scraper plate 1 is a trapezoidal plate structure with one end larger than the other end. The small end of the scraper plate 1 is connected to a connecting plate 5. The bottom end of the connecting plate 5 is fixed with a mounting frame 4. A fixing component 3 connected to the nozzle of the concrete mortar wet spraying machine is installed on the mounting frame 4. The fixing component 3 includes a handwheel 301, a clamping plate 302, a bidirectional screw 303, a slide groove 304, a sliding edge 305 and a moving block 306. During installation, the nozzle of the concrete mortar wet spraying machine is placed between the clamping plates 302, and then the handwheel 301 is rotated to rotate the bidirectional screw 303, so that the two clamping plates 302 are clamped close to the outer wall of the nozzle of the concrete mortar wet spraying machine under the action of the thread transmission, thereby realizing reliable installation of the scraper plate 1. After installation, the concrete mortar sprayed on the inner wall of the tunnel is scraped flat by making the scraper plate 1 follow the movement of the mechanical arm at the nozzle of the concrete mortar wet spraying machine.

[0032] like Figure 1-Figure 3 As shown, in this embodiment, the mounting frame 4 is a square frame structure, the bidirectional screw 303 is rotatably mounted in the middle of the mounting frame 4, and the bidirectional screw 303 extends out of the mounting frame 4 at one end and is connected to the handwheel 301. There are two moving blocks 306, and each moving block 306 has a sliding edge 305 formed in the middle of the two short side walls. The moving block 306 is mainly used to realize the synchronous movement of the splint 302, so as to clamp the nozzle of the concrete mortar wet spraying machine with the help of the splint 302.

[0033] like Figure 1-Figure 3 As shown, in this embodiment, the slide groove 304 is opened in the installation frame 4 and cooperates with the sliding edge 305. The cooperation between the sliding edge 305 and the slide groove 304 can realize the convenient sliding adjustment of the moving block 306 in the installation frame 4. The bidirectional screw 303 runs through the two moving blocks 306, and the two moving blocks 306 are respectively screwed with the two sections of threads with opposite rotation directions on the bidirectional screw 303. After the bidirectional screw 303 is rotated, the two moving blocks 306 are brought close to each other under the cooperation of the two sections of threads with opposite rotation directions. The splint 302 is an arc-shaped structure, and a splint 302 is connected to the bottom end of each moving block 306. The arc-shaped splint 302 can better fit and clamp the outer wall of the nozzle of the concrete mortar wet spraying machine.

The cleaning plate 201 is close to the scraping surface of the scraper plate 1, and the electric telescopic rod 202 is installed between the cleaning plate 201 and the connecting plate 5. When cleaning the concrete mortar adhered to the scraper plate 1, the electric telescopic rod 202 is used to move the cleaning plate 201 along the scraping surface of the scraper plate 1, thereby realizing the cleaning of the concrete mortar adhered to the scraper plate 1.

[0035] The specific implementation process of this embodiment is as follows: when scraping the concrete mortar sprayed on the inner wall of the tunnel, first, the nozzle of the concrete mortar wet spraying machine is located between the clamping plates 302, and then the two-way screw 303 is rotated by the hand wheel 301 to clamp the two clamping plates 302 close to the outer wall of the nozzle of the concrete mortar wet spraying machine, so as to achieve the fixation of the scraper plate 1 at the nozzle of the concrete mortar wet spraying machine, and then the cleaning mechanism 2 is connected to the power supply and control components of the concrete mortar wet spraying machine, and the mechanical arm at the nozzle of the concrete mortar wet spraying machine is operated. The scraper is used to scrape the sprayed concrete mortar along the inner wall of the tunnel. During the scraping process, the concrete mortar adhering to the scraping surface of the scraper plate 1 can be cleaned by pushing the cleaning plate 201 to move by the electric telescopic rod 202. Under the action of this scraper, the concrete mortar sprayed on the inner wall of the tunnel can be automatically scraped and leveled by cooperating with the nozzle on the concrete mortar wet spraying machine, which eliminates the tedious operation of manual scraping, reduces the labor intensity, and makes the scraping efficiency of the concrete mortar sprayed on the inner wall of the tunnel higher.
