Description

road roller for building construction

technical field

The invention relates to the technical field of construction machinery, in particular to a road roller for building construction.

Background technique

Road rollers belong to the category of road equipment in construction machinery. They are widely used in the filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can roll sandy, semi-cohesive and cohesive soils, Subgrade stabilized soil and asphalt concrete pavement layer.

In the construction process, especially after the asphalt pavement of the road is laid, the road surface needs to be compacted by a road roller. The rollers of the existing road roller are easy to stick and attach a large amount of soil and gravel during the road rolling process, making the The rotation process of the pressure roller is not stable enough, which in turn affects the compaction effect on the ground; therefore, there is an urgent need for a road roller for construction to realize the smooth rotation of the pressure roller and improve the compaction effect of the road surface.

A road roller for building construction, comprising a connecting frame, on which a pressure roller and a rear wheel are rotated; The sliding rod is provided with a cushioning spring in the limiting sleeve, the upper end of the cushioning spring is fixed at the lower end of the sliding rod, and the lower end of the cushioning spring is fixed in the limiting sleeve; the end of the sliding rod away from the cushioning spring is fixed and installed horizontally There is a top plate, a hanger is vertically hung on the lower side of the top plate, a rotating rod is hinged on the lower side of the top board, a telescopic hydraulic cylinder is arranged between the rotating rod and the hanger, and one end of the telescopic hydraulic cylinder is hinged on the hanger , the other end of the telescopic hydraulic cylinder is hinged on the rotating rod; the end of the rotating rod far away from the top plate is connected with a scraper through a limit spring; the left side of the scraper is inclined with several scrapers; the scraper and The surface of the pressure roller abuts; the connecting frame is fixedly installed with a rotating motor, and the output shaft of the rotating motor is coaxially fixed with a rotating shaft, and the rotating shaft moves downward through the connecting frame; Steel wire brushes are uniformly arranged on the lower side; push rods are fixedly installed on the connecting frame and the top plate.

As a further improvement of the present invention, the hanger is located on the left side of the rotating rod.

As a further improvement of the present invention, the diameter of the pressure roller is the same as that of the rear wheel.

As a further improvement of the present invention, the scraper is made of flexible rubber material.

Compared with prior art, the beneficial effect of the present invention is:

In the present invention, the road surface is compacted by the pressure roller, and the scraping block can scrape off the soil or gravel adhered to the surface of the pressure roller by being close to the surface of the pressure roller, so as to avoid the influence of the soil or gravel on the rotation of the pressure roller , which improves the compaction effect of the pressure roller on the road surface; the rotation of the turntable drives the wire brush to rotate and clean the road surface to remove debris on the road surface, which not only cleans the road surface, but also ensures that the pressure roller can rotate smoothly on the road surface. The invention plays the role of cushioning and ensures the compaction effect of the road surface.

detailed description

Below in conjunction with specific embodiment, the technical scheme of this patent is described in further detail:

Please refer to Figure 1-2, a road roller for building construction, including a connecting frame 1, on which a pressure roller 2 and a rear wheel 16 are rotated; Cylinder 3, the sliding rod 5 is connected with the sliding type in the limit sleeve 3, and the cushion spring 4 is arranged in the limit sleeve 3, and the upper end of the cushion spring 4 is fixed on the lower end of the slide rod 5, and the lower end of the cushion spring 4 Fixed in the limit sleeve 3; the end of the sliding rod 5 away from the cushioning spring 4 is fixed and horizontally installed with a top plate 6, the lower side of the top plate 6 is vertically hung with a hanger 7, and the lower side of the top plate 6 is hinged with a rotating rod 9, A telescopic hydraulic cylinder 8 is arranged between the rotating rod 9 and the hanger 7, one end of the telescopic hydraulic cylinder 8 is hinged on the hanger 7, and the other end of the telescopic hydraulic cylinder 8 is hinged on the rotating rod 9; The end of the rotating rod 9 away from the top plate 6 is connected with a scraper 11 through a limit spring 10; a number of scrapers 18 are inclined on the left side of the scraper 11; the scraper 18 is in contact with the surface of the pressure roller 2; A rotating motor 12 is fixedly installed on the connecting frame 1, and a rotating shaft 15 is fixedly installed coaxially on the output shaft of the rotating motor 12. The rotating shaft 15 moves downwards through the connecting frame 1, and a turntable 13 is fixedly installed at the lower end of the rotating shaft 15. Wire brushes 14 are evenly provided on the lower side of the turntable 13; push rods 17 are fixedly installed on the connecting frame 1 and the top plate 6.
