Description

Technical Field

[0001] The utility model belongs to the technical field of road maintenance equipment, and in particular relates to ground remote-controlled automatic milling equipment. Background Art

[0002] Currently, the most cost-effective pavement repair strategy is to use milling technology to first remove the damaged old pavement layer and then lay a new overlay. In this process, milling machines are mainly used for milling operations, which are widely used in renovation projects of highways, urban roads, airport runways and cargo loading and unloading areas. It can not only effectively solve common problems such as pavement bulges, oil waves, network cracks and rutting, but also assist in the excavation of potholes and ditches.

[0003] Traditional milling machines usually consist of a power source (motor or engine), a main structure, a milling cutter, a depth adjustment system, and travel wheels. When working, the motor drives the cutter to rotate at high speed, and the machine is guided to mill the road material through human push and pull. However, this human-driven method has obvious defects. The strong reaction force generated during the milling process requires the operator to exert great physical strength to stabilize the machine and prevent it from retreating. This not only puts a severe test on the operator's physical strength, but long-term high-intensity labor may also cause excessive fatigue or even physical injury, especially when working in a hot environment. The risk of heat stroke increases significantly. In addition, the operator's need for rest has also become a major factor restricting the continuity and efficiency of construction.

[0004] Therefore, it is necessary to develop a milling equipment that can be remotely operated. The equipment should be equipped with a remote control function, allowing the operator to control the travel component through the remote control from a safe distance to realize the forward, backward and steering of the milling machine, and at the same time control the lifting component to adjust the milling tool to lift or lower, thereby replacing manual operation. This design can not only significantly reduce the labor intensity of the operator and avoid health problems caused by overwork, but also improve construction efficiency, ensure operational safety, and bring revolutionary changes to road repair projects.
