The shaft drilling machine is widely used, and has the advantages of simple equipment, simple construction method, low equipment cost and high construction cost, but has high risk. The shaft shield machine is suitable for large and deep shaft construction and stratum with high rock hardness. The shaft tunneling machine is quite different from the horizontal tunneling machine, and generally looks more like a tunneling and anchoring integrated machine by cutting method. The shaft tunneling machine has the characteristics of relatively simple equipment, shield method and low construction efficiency than the shield machine, but higher than the drilling machine, and is used for large shaft construction.

[0003] When the shaft shield machine and the tunneling machine are tunneling, all the tunneling units are lowered into the shaft, and the power unit (hydraulic station), electrical system and operation room are on the ground. Therefore, the oil line, cable and mud pipeline between the two parts of the equipment on the ground and in the shaft need to be connected and lowered downward with the tunneling equipment, and the pipeline also needs to be lowered with the sinking of the equipment. When the equipment is lifted out of the shaft, the pipeline also needs to be lifted synchronously.

[0004] Therefore, it is necessary to design a pipeline follow-up mechanism to wind and unwind the pipeline. UTILITY MODEL CONTENTS

The wall penetrating connector plate assembly comprises a wall penetrating connector plate, the plate surface of the wall penetrating connector plate is provided with a pipeline connector, the left and right sides of the wall penetrating connector plate are provided with side ears, and the two side ears are respectively fixed with a second short ring chain. The wall penetrating connector plate is used as the connector of the extended pipeline. The first short ring chain and the second short ring chain are connected to form a continuous short ring chain, which is used to connect two adjacent wall penetrating connector plate assemblies. The chain wheel assembly comprises a chain wheel engaged with the continuous short ring chain, which is used to drive the wall penetrating connector plate assembly to move along the arch-shaped slide through the continuous short ring chain, so as to realize the sinking and recovery of the pipeline.

[0007] Further, the chain links at the two ends of the second short ring chain are provided with loose joints, which are used for quick connection with the first short ring chain.

[0008] Further, the bottom side of the wall-through connector plate is further provided with a guide rail perpendicular to the plate surface and matched with the arched slide, and the front and rear ends of the guide rail are upwardly curved.

[0009] Further, the top side of the wall-through connector plate is further provided with an ear.

[0010] Further, the chain wheel assembly further comprises a servo motor and a speed reducer for driving the chain wheel; and the pipeline follow-up mechanism further comprises a control module, which is used for receiving displacement data of a tunneling unit of the shaft shield tunneling machine and controlling the servo motor, so that the chain wheel assembly matches the displacement of the tunneling unit of the shaft shield tunneling machine in conveying the short link chain.
