Description

Technical Field

[0001] This utility model relates to the field of engineering construction equipment, specifically to a road roller that is easy to assemble. Background Technology

[0002] During operation, the steel cylinder of a road roller needs to have the dirt adhered to it scraped off by scrapers installed on its sides. The existing scrapers have circular through holes (A-holes) at both ends, and the mounting plate on the road roller frame has circular through holes (B-holes) for mounting the scrapers. The scrapers are assembled onto the frame using mounting bolts, through the A-holes, and through the B-holes. Since the road roller frame is also pre-assembled, there are machining and assembly errors in the parts, and the scrapers are generally assembled relatively late. Therefore, during assembly, the A-holes on the scraper and the B-holes on the mounting plate often do not align correctly, making it impossible to install the scraper and affecting assembly efficiency. Therefore, it is necessary to solve this problem. Utility Model Content

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] As used herein, the terms “parallel,” “perpendicular,” and the like are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors.

[0022] The technical solution provided by this utility model is as follows: Figure 1 , 2 As shown, a road roller that is easy to assemble includes a frame 10, a steel cylinder 11 is mounted on the frame 10, a scraper 20 is mounted on the side of the steel cylinder 11, and side mounting plates 12 are respectively mounted on the outer sides of both ends of the steel cylinder 11. The two ends of the scraper 20 are respectively mounted on the side mounting plates 12 through adjusting mounting units. The end of the scraper 20 has an A1 mounting part, the side mounting plate 12 has an A2 mounting part, the adjusting mounting unit has a B1 mounting part and a B2 mounting part, an A locking assembly is provided between the A1 mounting part and the B1 mounting part, and a B locking assembly is provided between the A2 mounting part and the B2 mounting part.

[0023] A further embodiment is as follows: Assembly part A1 is composed of A1 oblong hole 21, and assembly part B1 is composed of B1 oblong hole 31. The length direction of A1 oblong hole 21 and the length direction of B1 oblong hole 31 are arranged perpendicularly. A preferred embodiment is as follows: Scraper 20 is composed of an L-shaped plate, which includes a horizontally arranged A1 plate body and a vertically arranged A2 plate body. The lower edge of the A2 plate body is used to scrape the soil off the steel cylinder 11. The oblong hole A1 is provided on the A1 plate body. The length direction of A1 oblong hole 21 is arranged perpendicularly to the length direction of scraper 20.

[0024] The above solution allows for horizontal adjustment of the installation dimensions by setting horizontally arranged A1 waist-shaped holes 21 on the adjustment and installation unit, and vertical adjustment of the installation dimensions by using B1 waist-shaped holes 31 on the scraper 20. This makes the installation dimensions of the scraper 20 adjustable, avoids over-constraint, and simplifies the traditional box structure to an L-shaped plate structure, thereby simplifying the structure, reducing production costs, and avoiding over-constraint.

[0025] A further proposed solution is as follows: n A1 waist-shaped holes 21 are respectively set at each end of the scraper 20. The A1 waist-shaped holes 21 are spaced apart along the length of the scraper 20. n B1 waist-shaped holes 31 are set corresponding to the A1 waist-shaped holes 21, where n≥2, preferably n=2. This makes the installation more secure and extends the service life.

[0026] like Figure 3 As shown, the adjustment and installation unit includes an adjustment and installation component 30, which is composed of a folded component. The strip-shaped installation component includes a B1 strip body and a B2 strip body. The B1 strip body and the A1 plate body are fitted together, and the B2 strip body and the side mounting plate 12 are fitted together. The B1 waist-shaped hole 31 is provided on the B1 strip body. The A locking assembly includes an A locking block 41. The B1 strip body and the A locking block 41 are respectively placed on the upper and lower sides of the A1 plate body. The A locking block 41 is provided with two fixedly assembled A screws. The A screws are inserted into the A1 waist-shaped hole 21 and the B1 waist-shaped hole 31. The A screws extend to the upper side of the B1 strip body and are provided with A locking nuts 42. The A2 assembly is formed by circular A2 assembly holes on the side mounting plate 12, and the B2 assembly is formed by circular B2 assembly holes 32 on the B2 strip body. Two A2 assembly holes are provided, and two B2 assembly holes 32 are provided along the length of the B2 strip body. The B locking assembly includes a B locking block 43. The side mounting plate 12 and the B locking block 43 are respectively placed on the two outer sides of the B2 strip body. Two B screws are provided on the B locking block 43 for fixed assembly. The B screws are inserted into the A2 assembly holes and B2 assembly holes 32, and B locking nuts 44 are provided on the rods extending to the outer side of the side mounting plate 12. The above-described adjusting mounting part 30, the A locking assembly, and the B locking assembly can reliably assemble the scraper 20, and the assembly operation is simple and convenient, improving assembly efficiency.

[0027] In summary, this utility model, through its adjustable installation unit, compensates for assembly errors and component processing errors, enabling the scraper 20 to be assembled conveniently and quickly, thereby improving assembly efficiency.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
