Cutting device for digging robot

Abstract

The invention discloses a cutting device for a digging robot. The device comprises a mechanical arm and a cutting machine which is driven by the mechanical arm to move in the space; the mechanical armcomprises a machine base, an inner arm which is rotatably connected to the machine base at the single degree of freedom in the vertical direction, an outer arm which is rotatably connected to the inner arm at the single degree of freedom in the vertical direction, a first driving device for driving the outer arm to rotate relative to the inner arm and a second driving device for driving the innerarm to rotate relative to the machine base. Therefore, the mechanical arm with high length and weight can be adopted for the cutting device for the digging robot, the bending moment generated under the gravity of the mechanical arm is prevented from damaging the driving devices (usually gear motors), and accordingly the operation range of the cutting device for the digging robot is greatly enlarged.

Description

technical field [0001] The invention relates to the field of cutting, in particular to a cutting device for an excavating robot. Background technique [0002] The pipe corridor (called "common ditch" in Japan and "common pipeline" in Taiwan) is a comprehensive corridor of underground urban pipelines. That is to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports, hoisting ports and monitoring systems, implementing unified planning, unified design, Unified construction and management is an important infrastructure and "lifeline" to ensure the operation of the city. It is generally "open" type, the main place for centralized laying of large-scale installation pipelines, it is composed of columns, beams and trusses of steel structure or reinforced concrete structure, and can be divided into single-layer or multi-layer according to the t...

Problems solved by technology

[0004] The first is that workers hold conventional drilling tools, such as rhinestones or barrel drills, to drill a section of rock and then take it out, and continue to drill the next section. This method is time-consuming and labor-intensive in the process. A 3m*3m square hole, Two workers can only dig 1-1.2m a day, which is very inefficient and affects the construction period;

[0005] The second is to use a shield machine for excavation, but the cost of the shield machine is too high, and the cost of tens of millions or even hundreds of millions of dollars makes many construction parties discouraged
