Road roller

Abstract

The invention discloses a road roller, which comprises a pinch roller frame and a vibrating wheel which is arranged in the pinch roller frame. The road roller is characterized by also comprising wheels and elevating devices for controlling the wheels to ascend and descend relative to the vibrating wheel, wherein the wheels are connected with the pinch roller frame through the elevating devices. When the road roller is in the working state, the wheels can be elevated and retracted by the elevating devices, and the vibrating wheel runs; and when the road roller is required to be transported to another place, the wheels are lowered by the elevating devices, the vibrating wheel is lifted away from the road surface, the road roller walks under the action of the wheels and a back wheel, self-propelled traveling function is realized, and a special transportation tool is not needed for transferring the road roller, so that time and cost are saved for users.

Description

Technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a road roller. Background technique [0002] Road rollers are indispensable machinery and equipment when building roads, and single-drum vibratory rollers are a type of road roller used to compact roadbed materials. [0003] Please refer to figure 1 with figure 2 , figure 1 It is a schematic structural diagram of a typical single-drum vibratory roller; figure 2 for figure 1 Schematic diagram of the structure of the middle pressure wheel frame [0004] The complete vehicle of a single steel wheel vibratory roller usually consists of a cab 500, a rear frame 300, a tire 400, a vibrating wheel 200, and a roller frame 100. The rear frame 300 is located at the rear of the vehicle, and tires 400 are arranged on both sides. The rear frame 300 and the pressure wheel frame 100 located at the front of the vehicle are hinged by a hinged shaft. The pressure wheel frame 100 is composed...

AI Technical Summary

Problems solved by technology

[0007] Since the vibration wheel 200 is a steel roller, in order to prevent the steel wheel from damaging the road surface during driving, the relevant regulations do not allow the steel wheel to drive directly on the road. Therefore, the single-steel-wheel vibratory roller needs to be towed by vehicles when transferring to the construction site, and the transfer process is complicated. Especially in the case of short-distance transfer, the transfer is more inconvenient. Moreover, when using ordinary trucks for transfer, a crane is needed to hoist the roller, which increases the construction cost
