A dual-mode support control system and method

Abstract

The invention discloses a dual-mode support control system and method, which includes: a steel formwork assembly part, a steel arch traction device, a steel arch assembly frame fixedly connected to a fixed ring, and a steel arch assembly frame installed on the steel arch assembly frame. Multiple steel arch grippers, several steel arch lifting mechanisms, the steel arch assembly frame is in the form of a ring, each steel arch gripper includes a telescopic component, and multiple groups of guides installed on the telescopic component and whose relative spacing can be adjusted The wheel assembly, the wireless transmitter triggers the signal of the steel arch assembly machine and the steel formwork assembly machine, wirelessly transmits to the remote control receiver, and then transmits to the PLC through the PROFIBUS‑DP industrial communication network, and then the PLC processes through the control program , and send the corresponding action signal to the steel formwork and steel arch interface module, and finally transmit it to the actuator to trigger the action. The invention mainly assists the TBM tunneling process to support complex surrounding rocks, so as to realize the safe, fast and efficient tunneling of the TBM.

Description

technical field [0001] The invention belongs to the field of shield machine equipment, and in particular relates to a dual-mode support control system and method. Background technique [0002] Tunnel Boring Machine TBM (Tunnel Boring Machine) is a comprehensive equipment that uses mechanical crushing of rocks, mining and support for continuous operation. It is developed from shield technology. The types are mainly divided into open type and shield type, and the corresponding support forms are also different. The open type TBM is equipped with auxiliary equipment such as steel arch installers and spray anchors for support, and the shield type TBM uses steel formwork support as the support in the cave. means. Generally, TBM corresponds to the selected geology. Open TBM is usually used in hard rock with better formation, and shield TBM can adapt to soft rock, hard rock or soft-hard rock alternate formation. However, there are strata with complex surrounding rocks in the worki...

AI Technical Summary

Problems solved by technology

However, there are strata with complex surrounding rocks in the working conditions, and the surrounding rocks of types II and III are mostly mixed with surrounding rocks of types IV and V. If an open TBM is used, the surrounding rocks of types II and III The amount of medium support is small, the risk of construction safety is low, and the amount of steel arch materials is saved. When encountering Class IV and Class V surrounding rocks, the installation amount of steel arch frames and the workload of construction will be increased, and large deformation and landslides of soft rock may also occur. If it is too late to do steel arch support, it will cause destructive damage to the equipment; if a shield-type TBM is used, steel formwork support can avoid the above problems and ensure the safety of construction personnel. It is relatively long, and steel formwork in Type II and III surrounding rocks will take up a lot of excavation time and material resources, while in Type IV and V surrounding rocks, steel formwork can well support and prevent deformation and protect construction safety
