A tunnel construction trolley

Abstract

The invention discloses a tunnel construction trolley. The tunnel construction trolley comprises a walking mechanism, a lifting platform, a drill arm mechanism, a lifting mechanism and a power and control device, wherein the walking mechanism is located on the bottom of a trolley body, and the power and control device is installed on the walking mechanism; the lifting platform is arranged above the walking mechanism in a liftable mode; the drill arm mechanism and the lifting mechanism are both installed on the lifting platform; the power and control device controls the lifting platform, the drill arm mechanism and the lifting mechanism to act. According to the tunnel construction trolley, anchor protection and lifting are integrated, not only can the construction requirement for the inland tunnel anchor bolt support be met, but also the mechanization and the automation of large section tunnel anchor bolt support work are achieved, the labor intensity is relieved, the efficiency is improved, and a better guarantee of the tunnel engineering quality is achieved.

Problems solved by technology

[0002] China is one of the countries with the most railways and highway tunnels and the longest total extension in the world, and in the next few decades, my country will build a large number of new railways and highways, including a large number of mountainous railways and highways, The terrain and geological conditions of some tunnels are very complicated, the adverse geological phenomena are serious, and the construction conditions are very poor. If the level of mechanization and automation of tunnel construction is not improved, it will be difficult to increase the construction speed of tunnels, which will inevitably affect the development of tunnel construction.

[0003] At present, most of the tunnel construction technologies at home and abroad adopt the "New Austrian Method", and its core technology is to carry out tunnel bolt support, so that the support becomes passive and active. However, at present, there is no special mechanized equipment for tunnel bolt support in my country. As a result, bolt construction is rarely used in the construction process of railway and highway tunnels. Even if bolt support is carried out, most of them are carried out manually. The labor intensity of workers is high, the safety is poor, and the efficiency is low.

Although some foreign tunnel bolting equipment is relatively mature, the number of arms of the bolting equipment is small, the efficiency is low, and it is not suitable for the technology and working conditions of domestic tunnel construction, making the existing tunnel bolting equipment difficult To meet the construction requirements of domestic tunnel bolt support, especially for large-section tunnels, there are many shortcomings such as large-scale employment, high cost, and low efficiency. Therefore, it has become one of the important links in tunnel construction to improve the mechanization of tunnel bolt support and ensure the quality of the project. one
