Description

Technical Field

[0001] The utility model relates to a cement scraping device, belonging to the technical field of road construction. Background Art

[0002] When pouring cement concrete pavement, it is necessary to lay out cross-sectional templates on both sides of the roadbed, pour cement concrete onto the roadbed, so that the template can restrict the cement concrete. After the cement concrete is poured onto the roadbed, it is uneven, so it is necessary to use a scraper to scrape the uneven cement mortar, so that the two ends of the scraper overlap the templates on both sides of the roadbed, and then use the handle to pull the scraper. In the process of pulling the scraper, more cement mortar will gather on the front side of the scraper, which will cause the resistance to pulling the scraper to become greater and greater, and the labor intensity is high. Therefore, it is necessary to design a cement scraping device that reduces the labor intensity. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a cement scraping device to solve the problems raised in the above-mentioned background technology. The utility model can locally push the accumulated cement mortar and reduce the labor intensity.

[0005] Furthermore, a slat is connected and fixed to the lower position of one side of the guide rail, and two symmetrically arranged long circular openings are opened on the upper surface of the slat, a positioning rod is inserted in the long circular opening, a pointed head is connected and fixed to the lower end of the positioning rod, an external thread is processed on the outer surface of the upper end of the positioning rod, and two nuts are threadedly connected to the positioning rod, and the two nuts on the positioning rod are respectively arranged on the upper and lower sides of the long circular opening.

[0006] Furthermore, two areas of the bottom of the guide rail near its ends are recessed downward to form a stepped groove, and two countersunk holes are symmetrically provided at the bottom of the guide rail, and the two countersunk holes are respectively connected to the two stepped grooves, and connecting plates are inserted in the two stepped grooves where two adjacent guide rails are connected, and hexagon socket screws threadedly connected to the connecting plate are inserted in the countersunk holes.

[0007] Furthermore, a first ball head is connected and fixed to one end of the handle away from the scraper, and a second ball head is connected and fixed to one end of the handle away from the insert plate.

[0008] Furthermore, a connecting ear is fixedly connected to one end of the handle away from the first ball head, and the connecting ear is fixed at a middle position of the upper surface of the scraper.

[0010] Beneficial effects of the utility model:

[0011] 1. When a lot of cement mortar gathers on the front side of the scraper, stop pulling the scraper, then insert the plug plate into the space formed by an end plate and the corresponding U-shaped frame, use the handle to pull the end plate, so that the end plate pushes the gathered cement mortar away from the scraper, and the handle is plugged into different end plates, which is convenient for pulling multiple end plates in sequence. When pulling the end plate, the guide rod slides along the guide hole to limit the moving trajectory of the end plate. Because the end plate is shorter than the end plate, the gathered cement mortar has less resistance to the end plate when pulling the end plate, so that the gathered cement mortar can be partially pushed and the labor intensity can be reduced.

[0012] 2. The two sliders on the scraper are slidably installed in the guide rail, and the position of the guide rail is limited by the combination of nuts and positioning rods, so that the position of the guide rail is limited, and the guide rail limits the moving trajectory of the scraper.

[0013] 3. After inserting the lower end of the positioning rod into the ground and passing the positioning rod through the long round opening, adjust the position of the two nuts on one positioning rod on the positioning rod to facilitate adjusting the guide rail to a horizontal state.

The two steps connected to the two adjacent guide rails 9 A connecting plate 14 is inserted in the groove 15, and a hexagon socket screw threadedly connected to the connecting plate 14 is inserted in the countersunk hole, so that the two sliders 16 on the scraper 1 are slidably installed in the guide rail 9, and the position of the guide rail 9 is limited by the cooperation of the nut 13 and the positioning rod 11, so that the position of the guide rail 9 is limited, and the guide rail 9 limits the movement trajectory of the scraper 1. After the lower end of the positioning rod 11 is inserted in the ground, and the positioning rod 11 passes through the long round opening 12, the two nuts 13 on a positioning rod 11 are adjusted in the position of the positioning rod 11, so as to facilitate the adjustment of the guide rail 9 to a horizontal state, and the two guide rails 9 are connected by the connecting plate 14 to realize the assembly between the two guide rails 9, and so on, the assembly of multiple guide rails 9 is completed, and the number of guide rails 9 can be increased or decreased according to needs, so that the length of the guide rail 9 is miniaturized, which is convenient for the storage and transportation of the guide rail 9.

[0026] See also Figure 1-Figure 4The scraper 1 is provided with a plurality of end plates 7 in contact with each other on the side facing the handle 6. Two guide rods 2 are installed on the side of the end plate 7 facing the scraper 1. A guide hole 17 matching with the guide rod 2 is provided in the area of ​​the scraper 1 covered by the end plate 7. The guide rod 2 passes through the guide hole 17. A threaded cap 3 is threadedly connected to the end of the guide rod 2 away from the end plate 7. The outer diameter of the threaded cap 3 is larger than the inner diameter of the guide hole 17. The threaded cap 3 prevents the guide rod 2 from escaping from the guide hole 17.

When a lot of cement mortar gathers on the front side of the scraper 1, stop pulling the scraper 1, and then insert the plug plate 19 into the space formed by an end plate 7 and a corresponding U-shaped frame 8. The handle 5 is used to pull the end plate 7, so that the end plate 7 pushes the gathered cement mortar away from the scraper 1, so that the handle 5 is plugged into different end plates 7, which is convenient for pulling multiple end plates 7 in sequence. When the end plate 7 is pulled, the guide rod 2 slides along the guide hole 17 to limit the moving trajectory of the end plate 7. Because the end plate 7 is shorter than the end plate 7, the gathered cement mortar has less resistance to the end plate 7 when the end plate 7 is pulled, so that the gathered cement mortar is partially pushed and the labor intensity is reduced.
