[0027] A push plate 20, the push plate 20 is fixedly connected to the telescopic ends of two second cylinders 12.
[0028] In a specific embodiment of the present utility model, the connection frame 1 serves as the main frame of the entire support device, providing stability and structural support. The limiting holes 16 on the inner walls on both sides are used to install the lead screw and the limiting rod 14 to ensure the linearity and stability of the adjusting plate 6 during movement. The adjusting plate 6 and the electric mechanical gripper 10: The adjusting plate 6 is the core part of the device and can slide along the limiting rod 14 and the lead screw inside the connection frame 1 to achieve position adjustment in the horizontal direction. The electric mechanical gripper 10 is responsible for grasping the tunnel I-beam construction steel 11, improving the operation efficiency and safety. The motor 4 and the lead screw 21: The motor 4 drives the rotation of the lead screw, and the thread fit between the lead screw and the nut enables the adjusting plate 6 to perform linear motion on the limiting rod 14, thereby achieving the purpose of precise adjustment. The limiting rod 14 and the nut 9: The limiting rod 14 ensures the linear motion of the adjusting plate 6 and prevents it from deviating during movement. The threaded connection between the nut and the lead screw converts the rotational motion of the motor 4 into the linear motion of the adjusting plate 6. The first cylinder 7 and the connecting plate 8: The first cylinder is used to provide the supporting force in the vertical direction, and the connecting plate 8 transmits this force to the structure that needs to be supported, such as the tunnel roof or side wall, enhancing the overall stability. The second cylinder 12 and the push plate 20: The function of the second cylinder is to provide additional supporting force or thrust. The push plate 20 can contact and support a certain area of the tunnel, especially in the case where the supporting strength needs to be temporarily increased. It should be noted that: The specific models of the second cylinder 12, the cylinder 7, the electric mechanical gripper 10, and the intelligent controller 5 are selected by those skilled in the relevant art. The above-mentioned second cylinder 12, the cylinder 7, the electric mechanical gripper 10, and the intelligent controller 5, etc. all belong to the prior art, and this solution will not be elaborated.
[0029] Specifically, please refer to Figures 1 - 3 , two clamping plates 17 are movably clamped inside the tunnel I-beam construction steel 11, two bolts 18 are movably clamped inside the two clamping plates 17, a screw rod 19 is threadedly connected inside the two bolts 18, one side end of the connection frame 1 is fixedly connected with an intelligent controller 5, and the second cylinder 12, the cylinder 7, the electric mechanical gripper 10, and the intelligent controller 5 are electrically connected.
[0030] In this embodiment: The I-shaped construction steel for tunnels 11 and the clamping plate 17: The I-shaped construction steel is a key load-bearing member in the tunnel support structure. The setting of the clamping plate 17 enables the support device to be firmly fixed on the I-shaped steel, and it can remain stable even in the complex and changeable underground environment. By adjusting the angle and position of the clamping plate 17, it can adapt to I-shaped steels of different sizes and shapes, improving the versatility and adaptability of the device. The bolt 18 and the screw rod 19: The combination of the bolt 18 and the screw rod 19 provides an additional fastening effect, ensuring that the clamping plate 17 is more securely fixed on the I-shaped steel. By tightening the bolt 18, sufficient pre-tightening force can be applied to prevent loosening caused by vibration or external impact, thus ensuring the safety of the entire support system. The intelligent controller 5: It is responsible for receiving sensor data, processing information, and controlling the actions of actuators such as the electro-mechanical gripper 10, the first cylinder 7, and the second cylinder 12. It can automatically adjust the working mode of the device according to the specific situation of tunnel construction. For example, when encountering geological changes, it can quickly adjust the support force or position to cope with emergencies. Electrical connection: The electrical connection between all key components including the electro-mechanical gripper 10, the cylinders, and the intelligent controller 5 means that the operation of the device can be uniformly coordinated and managed through the intelligent controller 5.
[0031] For details, please refer to Figures 1 - 3 Both ends of the connection frame 1 are fixedly connected with protective plates 2. The top end of the connection frame 1 is fixedly connected with a lighting lamp 13 and a length scale 15. Four corners at the bottom end of the connection frame 1 are fixedly connected with support plates 3.
[0032] In this embodiment: The protective plates 2 are fixed at both ends of the connection frame 1, mainly playing a protective role to prevent the device from being accidentally impacted during movement or use. At the same time, it can also prevent staff from directly contacting the mechanical structure inside the device, improving operation safety. The tunnel construction environment is usually dimly lit. The setting of the lighting lamp 13 ensures sufficient illumination in the working area, facilitating construction workers to observe and operate. It also facilitates the device's night work, improving work efficiency and safety. The integration of the length scale 15 provides a convenient measurement method, enabling construction workers to quickly and accurately measure distances, which is crucial for adjusting the device position and ensuring the precise installation of the support structure, and helps to improve the project quality and construction efficiency. The support plates 3 are at the four corners of the bottom end of the connection frame 1. Its main function is to provide a stable base to ensure that the device can remain balanced on uneven ground, preventing the device from tilting or sliding. Especially in tunnel construction with unstable geological conditions or narrow spaces, the role of the support plates 3 is particularly prominent.

Position the I-shaped building steel 11: Use the electric mechanical gripper 10 to grab the tunnel I-shaped building steel to a predetermined position, and firmly fix the I-shaped building steel through the cooperation of the clamping plate 17, bolts 18, and screw rod 19. Adjust the support device: The motor 4 drives the screw rod 21 to rotate, and the threaded cooperation between the screw rod and the nut 9 drives the adjusting plate 6 to linearly move along the limit rod 14 to achieve precise adjustment of the support position. Provide support force: The first cylinder 7 and the second cylinder 12 provide vertical and lateral support forces to the tunnel roof or side wall through the connecting plate 8 and the push plate 20 to enhance the support stability. Intelligent monitoring and adjustment: The intelligent controller 5 automatically adjusts the working mode of the equipment according to the sensor data. When encountering geological changes, it quickly adjusts the support force or position to cope with emergencies. Safety guarantee: The protection plate 2 protects the equipment from external impacts, and the support plate 3 ensures the stability of the equipment on uneven ground. Auxiliary function: The lighting lamp 13 provides sufficient light for construction at night or in low-light environments, and the length scale 15 facilitates measuring and adjusting the position of the equipment. Unified coordination and management: All key components are electrically connected and are uniformly coordinated and managed by the intelligent controller 5 to simplify the operation process and improve the operation efficiency and safety of the equipment.
