Unmanned chain type excavation device, unmanned operation system and unmanned operation method

Abstract

The invention discloses an unmanned chain type excavation device, an unmanned operation system and an unmanned operation method, and belongs to the technical field of road and mechanical engineering. The positioning unit is arranged on the vehicle body and is used for sending a positioning request to a plurality of positioning base stations located at the periphery, so that the server positions the position of the unmanned chain type excavation device; the power output unit is arranged on the vehicle body and used for providing driving power; the operation execution unit is arranged on the vehicle body, is in driving connection with the power output unit and is used for excavating the land; and the control processing unit is mounted on the vehicle body, connected with the operation execution unit and used for responding to an operation instruction sent by the server according to the position of the positioning unit, controlling the vehicle body to move to the target area and performing operation in the target area. Rapid construction and one-time forming of roadbed steps can be achieved, the construction workload is reduced, the engineering period is shortened, and the settlement difference between widening of new and old roadbeds is reduced, so that the construction quality of the widening roadbed is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of road and mechanical engineering, and specifically relates to an intelligent unmanned chain-type excavation device, an unmanned operation system and an unmanned operation method based on unmanned driving for road reconstruction and expansion of old subgrade steps. Background technique [0002] With the rapid development of my country's national economy, many two-way four-lane expressways built in the early stage of the country can no longer meet the travel requirements of the existing traffic flow. Expressway reconstruction and expansion projects have become a key issue in the development of expressways in recent years. The main direction of highway development is necessary for the research on the reconstruction and expansion of expressways under various construction conditions. Subgrade widening and splicing is an important research content of highway reconstruction and expansion, especially for the rapid d...

Problems solved by technology

[0005] (1) In the process of reconstruction and expansion of old roads, it is necessary to set multiple steps on the joint surface between the new roadbed and the old roadbed. The steps include horizontal joint surfaces and vertical joint surfaces. Traditional step excavation equipment adopts general-purpose bucket excavation. machine, without professional equipment, the excavated steps are uneven and need to be leveled in the later stage; and the excavation operation cannot be carried out continuously, the efficiency is low, the construction period is long, and the cost is high;

[0006] (2) When the new subgrade and the old subgrade are over-excavated to form the wide-faced steps, the previous slope-clearing operations are all asynchronous construction, so that the step slopes on both sides form different tensile structures during the foundation building process. At the same time, the slope dikes on both sides of the old subgrade have changed over a long period of time, and the angles of the slope dikes on both sides are different, which has caused certain difficulties in excavating and clearing the slope, thus affecting the laying of the new subgrade base.

[0007] (3) The step excavation equipment is manually driven, the labor cost is high, and large-scale mechanized construction cannot be achieved, and the engineering efficiency is low. Especially in the construction of roads with heavy traffic such as expressways, the construction period is long and the economic benefits are greatly affected.
