Walking telescopic arm type remote control digging machine

Abstract

Disclosed is a walking type and telescopic arm type remote control excavating machine applied to construction machinery of underground engineering, which comprises folding telescopic excavators, a chassis, a telescopic excavating mechanism, a walking mechanism and a remote control unit. Two folding telescopic excavators are positioned on the upper platform of the chassis in a manner of 180 degrees symmetry, and the middle of the upper platform is provided with a set of electric hydraulic pump to provide power to the excavators. The lower platform of the chassis is provided with the special walking mechanism; after the two excavators support the whole machine away from the ground, the lower platform is rotated so as to have the whole machine walk at any directions. Under the control of the remote control unit, the two excavators can carry out excavating works independently. The upper platform and the lower platform rotate relatively when the whole machine needs walking and are fixedly connected together under normal excavation. The two excavators are 12m long after lateral extension and the radius of one-arm excavation is 5m. The whole machine is driven by electric power and controlled by the remote control unit, and has large excavation radius and high borrow efficiency.

Description

technical field [0001] The invention relates to an underground engineering construction machine, in particular to a walking telescopic arm type remote control excavator for underground deep foundation pit excavation construction, air pressure caisson construction and cover excavation construction. Background technique [0002] With the continuous development of urban construction, there are more and more various types of underground projects and deep foundation projects. High-efficiency, safe, economical, energy-saving, and environmentally-friendly deep foundation pit construction methods are particularly important. At present, the excavation construction of deep foundation pits has the following problems: [0003] 1. The efficiency is not high; due to the many auxiliary facilities inside the foundation pit, the high groundwater level, and the muddy soil, it is difficult for traditional excavators to perform effectively; [0004] 2. There are many safety hazards, such as f...
