Steel arch splicing system of area L2 of heading machine

Abstract

The invention provides a steel arch splicing system of an area L2 of a heading machine. The area L2 of the heading machine is located behind an area L1 of the heading machine. An area L1 steel arch is arranged in the area L1 of the heading machine. An area L2 steel arch is arranged in the area L2 of the heading machine. The area L2 steel arch comprises an upper machine frame, a lower machine frame, an upper jacking mechanism, side jacking mechanisms, block connecting pieces, an upper traveling mechanism, side traveling mechanisms, a traction trolley and a driving winch. The upper traveling mechanism can be movably arranged on a frame of a rear support. The side traveling mechanisms can be movably arranged on the two sides of the frame of the rear support correspondingly. The upper jacking mechanism is arranged on the upper traveling mechanism. The side jacking mechanisms are arranged on the side traveling mechanisms. The split type upper machine frame is arranged on the upper jacking mechanism. The side jacking mechanisms are connected with the upper machine frame and the lower machine frame. On the premise that personnel and materials are smooth, the steel arch splicing system is located at the foremost end of the area L2 of the heading machine and located on the tail portion of a main beam of the heading machine, and the requirement of the heading machine for fast, safe and efficient construction can be met.

Description

technical field [0001] The invention belongs to a steel arch assembling system, in particular to a steel arch assembling system suitable for an open rock tunnel in the L2 area of ​​a boring machine. Background technique [0002] TBM (Tunnel Boring Machine) is a full-face tunnel boring machine. The construction procedures such as excavation, support, and slag discharge are operated in parallel and continuously. It is a factory-like assembly line tunnel construction equipment integrated with mechanical, electrical, hydraulic, optical, and gas systems. It has the advantages of fast excavation speed, environmental protection, and high comprehensive benefits. It can realize The construction of deep and long tunnels with complex geographical landforms, which is difficult to realize by traditional drilling and blasting methods, is rapidly growing in China's railway, hydropower, transportation, mining, municipal and other tunnel projects. [0003] The steel arch assembly system of ...

AI Technical Summary

Problems solved by technology

[0005] Especially when a large landslide occurs in the main engine area, dense steel arches are required to support the tunnel. Existing roadheaders can only manually erect the arch after the shoe, and erect the arch assembly in the area between the shoe and the rear support. The platform is assembled into a ring by manual lifting and other methods to support the cave wall. This method requires a lot of manpower, low work efficiency, high risk factor, and does not meet the requirements of fast, safe and efficient construction of the roadheader.
