Abstract

The invention provides an electric hydraulic excavator special for a tunnel. The electric hydraulic excavator special for the tunnel comprises a walking X frame assembly used for moving on the ground, an upper rack assembly serving as an external main body structure of the excavator, a power output assembly used for providing power support for the excavator and a mechanical arm assembly used for installing and driving an excavating workpiece to move. According to the electric hydraulic excavator special for the tunnel, the mechanical arm assembly is arranged and mainly used for achieving the excavation effect on the interior of the tunnel; the first supporting arm and the second supporting arm which are equal in length are arranged, so that the gyration radius of the first supporting arm and the gyration radius of the second supporting arm are further reduced; the first hydraulic assembly and the second hydraulic assembly are used for driving the first supporting arm and the second supporting arm to rotate respectively, so that the stretching amount of the first supporting arm and the second supporting arm is greatly reduced, and energy consumption is further reduced; and in addition, the maximum stretching amount of the first supporting arm and the second supporting arm is reduced, and the first supporting arm and the second supporting arm can freely move in the tunnel.

Description

technical field [0001] The invention relates to the field of excavators, in particular to an electro-hydraulic excavator dedicated to tunnels. Background technique [0002] Tunnels are engineering buildings buried in the ground, and are a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mine tunnels, and military tunnels. [0003] During the construction of the tunnel, a lot of construction equipment needs to be used, and the excavator is the most common one, which can excavate the non-explosive earthwork of the tunnel, and is generally composed of a walking mechanism, a machine body and an excavating mechanism. [0004] In the related art, the traditional excavator, due to the high height and length of the mechanical arm of the excavating mechanism, is easily restricted in the tunnel with limited space, which reduces the overall mobility of the excavator and cannot realize full-section excavation. An...
