Single-freedom-degree numerical control hole digging robot mechanism

Abstract

A single-freedom-degree numerical control hole digging robot mechanism comprises a main arm lifting mechanism, a horizontal maintaining branched chain and a tool bit platform. The numerical control hole digging robot mechanism is subjected to drive control through a servo motor system mounted on a rack. Under numerical control programming control of a computer, the tool bit platform does single-freedom-degree flexibility-controllable high-precision motion, and therefore the hole digging operation of a numerical control hole digging robot is achieved. All components of the numerical control hole digging robot mechanism are connected through rotary pairs, connecting rod transmission is utilized for replacing a hydraulic system frequently used by an existing hole digger, reliability is greatly improved, and the maintenance cost is reduced; the mechanical efficiency is greatly improved; and the problems that a hydraulic system is high in energy consumption, poor in reliability and the like are avoided. The numerical control hole digging robot developed through the structure design scheme has the beneficial effects of being low in noise, free of exhaust gas emission, low in energy consumption, highly intelligent and the like and is especially suitable for municipal engineering operation with urban road lamp pole embedding, landscape engineering and the like as the principal things in densely-populated areas.

Description

technical field [0001] The invention relates to the field of digging machines, in particular to a single-degree-of-freedom numerical control digging robot mechanism. Background technique [0002] A pit digger is a kind of mechanical equipment that uses an internal combustion engine as a power source and is equipped with a hydraulic system to excavate a pit. It is generally composed of a power system (tractor or excavator), a hydraulic system, and a mechanical drilling system. Composed of parts, the digging machine liberates people from heavy physical labor, and is widely used in road light poles, green digging, mountainous, hilly, and ravine area afforestation, and fertilization as a special machine for fast digging. [0003] However, when the digging machine is widely used, there are many problems. First of all, hydraulic valves and hydraulic circuits are the main causes of energy loss. Generally, the energy loss of hydraulic systems is as high as 30%. Existing excavators ...

Problems solved by technology

First of all, hydraulic valves and hydraulic circuits are the main causes of energy loss. Generally, the energy loss of hydraulic systems is as high as 30%. Existing excavators use hydraulic systems for power transmission, which not only consumes high energy, but also easily produces oil leakage. It pollutes the environment and greatly increases the cost of use and maintenance; secondly, the digging machine usually uses a diesel engine as the source power of the hydraulic transmission system, and there are still problems such as loud working noise and serious exhaust emissions. With the increasingly serious environmental problems, existing digging It is becoming more and more difficult for excavators to adapt to municipal projects in densely populated areas; in addition, with the implementation of the first-generation numerical control equipment innovation project, green, intelligent, and precise have become important development trends for mechanical equipment. The power and hydraulic systems of traditional excavators There are problems such as slow response speed and low motion accuracy, which make it difficult to meet the performance requirements of the new generation of digital equipment
