[0040] Specifically, this utility model provides a railway tunnel support structure. In use, the operator inputs a movement command via a touch panel. The built-in microprocessor receives the command and controls the built-in motor to start. The motor drives the moving rollers to rotate, moving the entire device within the railway tunnel. When the device reaches the designated position, the operator inputs a stop command via the touch panel, stopping the built-in motor and the device. After stopping, the operator inputs a fixing command via the touch panel. The built-in microprocessor receives the command and controls the extension of the small telescopic rod and the downward movement of the auger fixing component, inserting it into the railway tunnel floor to complete the device's operation. Once fixed, the small telescopic rod stops extending. Then, based on the size and shape of the railway tunnel, workers input adjustment commands for the support height and lateral position via a touch panel. The built-in microprocessor receives these commands and controls the hydraulic pump unit to start. The hydraulic pump unit then controls the extension and retraction of the large telescopic rod, telescopic support column, and lateral telescopic rod, adjusting the height and lateral position of the support components to stably support the tunnel wall. After adjustment, the hydraulic pump unit stops working, and each telescopic rod maintains its current length. When the device has completed the tunnel reinforcement and lining work and needs to be moved for the next stage of support work, workers input the support group settings via the touch panel. Upon receiving the adjustment command, the built-in microprocessor energizes the linear electromagnetic slide rail. Under electromagnetic force, the linear electromagnetic slider slides along the rail, causing the arc-shaped weight-reducing plate to adjust and move, ensuring the support assembly better fits the tunnel wall. Then, workers input adjustment commands for the moving and telescopic components via a touch panel. The adjustment device moves forward until the arc-shaped weight-reducing plate aligns with the tunnel wall, at which point the linear electromagnetic slide rail is de-energized, the slider stops sliding, and the telescopic component is adjusted to stably support the tunnel wall. This cycle can be repeated continuously for tunnel support operations. Furthermore, this device… Equipped with a wireless transmission module, workers can establish a wireless connection with the control module's wireless transmission module via an external remote control terminal (such as a mobile phone or computer) to send control commands. These commands are transmitted wirelessly to the built-in microprocessor, which then controls each component to perform corresponding actions. When tunnel construction is completed and the equipment needs to be disassembled and transported, workers use a touch panel to control the moving components to pull the auger fixing parts out of the ground. Then, they control the telescopic components to drive each telescopic rod to its shortest length. Finally, the large telescopic rod is disassembled from the telescopic rod joint and support components using detachable threaded connectors, and each component can be transported separately. This invention offers the advantages of flexible adjustment, convenient movement and fixing, good support stability, high construction efficiency, easy disassembly, assembly and maintenance, and a high degree of intelligence.
