Abstract

The invention discloses a lifting cab and a tunnel boring machine. The lifting cab comprises a cab, a fixed bracket, a connecting rod assembly and a driving mechanism, wherein the fixed bracket is fixedly arranged behind the cab; the connecting rod assembly at least comprises a first connecting rod and a second connecting rod which are arranged in parallel; first ends of both the first connecting rod and the second connecting rod are connected with the cab; second ends of both the first connecting rod and the second connecting rod are hinged with the fixed bracket; the driving mechanism is used for driving the connecting rod assembly to rotate along the vertical face. According to the lifting cab provided by the invention, a lifting device is arranged behind the cab, so that the space in the horizontal direction is effectively utilized, the mounting height of the complete machine in the vertical direction is reduced when the effective lifting height is ensured, and the lifting cab is beneficial for ensuring balance of the gravity center of the complete machine; the number of required driving parts is small, which is beneficial for reducing equipment cost; moreover, the lifting device is arranged behind the cab, so that the lifting cab also has the advantage of convenience for repair.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a lifting cab and a tunnel boring machine. Background technique [0002] Tunnel boring machine is a kind of important construction machinery, and its application is very extensive. Existing tunnel boring machines mainly include a traveling mechanism, a cab arranged on the traveling mechanism, and a cutting part arranged at the front end of the cab. Among them, the cab is fixed on the chassis of the traveling mechanism, so that the operator can explore the working conditions ahead. However, for some complex work transfers, such as a large tunnel section, if the fixed height of the cab is low, it is inevitable that the driver's line of sight will be blocked, which is not good for the operator's work; if the fixed height of the cab is high, it will As a result, the center of gravity of the equipment moves upward, which has a certain impact on the stability of the whole machine...
