Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0037] Rollers for road rollers, such as figure 1 As shown, it includes the traction frame 1, the rotating shaft 11 that is rotatably connected with the traction frame 1, and the smooth roller 12 fixed with the keyway of the rotating shaft 11. The circumferential mask of the smooth roller 12 is provided with four inner arc plates 13, and the inner arc The outer arc surface of the plate 13 is integrally formed with a plurality of sheep foot bumps 14, and the outer cover of each inner arc plate 13 is provided with an outer arc plate 15, and the outer arc surface of the outer arc plate 15 is integrally formed with impact bumps 16 .

[0038] When the present invention is working normally, the traction frame 1 is connected with the vehicle body, thereby being pulled forward by the vehicle body, and then realizes rolling on the ground; Inner arc plate 13, thereby...

Abstract

The invention discloses a runner wheel for a road roller, and relates to the road roller. The runner wheel for the road roller aims at solving the problem that conversion to impact milling cannot be completed in the prior art. According to the technical scheme points, the runner wheel for the road roller includes a traction frame, a rotating shaft rotatably connected with the traction frame and asmooth roller fixedly connected with the rotating shaft. The circumferential surface of the smooth roller is provided with four inner arc slabs in a covered mode, and the outer cambered surfaces of the inner arc slabs are provided with sheep foot protruding blocks. The inner arc slabs are externally provided with outer arc slabs in a covered mode, and the outer cambered surfaces of the outer arc slabs are provided with impact protruding blocks. According to the runner wheel for the road roller, the function of arbitrarily switch between three types of runner wheels of a light roller, a tampingroller and an impact roller is achieved, the functions of three runner wheels are integrated in the road roller, and the equipment cost is effectively reduced during road construction.

Description

technical field [0001] This invention relates to road rollers and, more particularly, to a drum for a road roller. Background technique [0002] 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. [0003] The rollers of the road roller include smooth rollers, sheep foot rollers and impact rollers. The smooth rollers are rollers with smooth peripheral surfaces. The sheep foot rollers are rollers with several trapezoidal bumps on the peripheral surface, and the impact rollers have multiple The grinding wheel of the arc protruding block. [0004] Since different rollers may be used during modern road construction, the Chinese Patent Announcement No. CN107489083...
