Description

Technical Field

[0001] This invention relates to the field of steel support connection technology, specifically to a steel support servo system conversion device. Background Technology

[0002] The effective connection between the steel support and the servo system, as well as the stable operation of the servo control system, are crucial for the safety of the foundation pit. Currently, there are different ways to connect the steel walers and the servo system, such as hanging plate connections and direct connections. It is necessary to ensure the robustness and stability of the connection to guarantee the effective transmission of force. Simultaneously, the servo control system needs to achieve real-time monitoring, automatic compensation, and fault alarm functions for the axial force of the steel support, thereby addressing potential changes in axial force during construction and preventing safety hazards such as excessive deformation of the retaining structure.

[0003] During construction, the steel support servo system needs to be installed and debugged in conjunction with the foundation pit excavation process. Its installation quality and control precision directly affect the stability of the foundation pit. Furthermore, due to the complex construction site environment and various risk factors, such as crane overturning and steel support instability, the servo control system must also possess high reliability and emergency response capabilities to ensure effective operation and construction safety in unexpected situations. Therefore, developing reliable steel plates for connecting the steel support and the servo system, as well as a highly efficient and stable servo control system, is of significant engineering importance.

[0004] Currently. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a steel-supported servo system conversion device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a steel support servo system conversion device, comprising a servo control system, one end of which is attached to one side of a connecting steel plate, and the other side of the connecting steel plate is attached to one end of a steel support;

[0007] The connecting steel plate is connected to the servo control system and the steel support using bolts and bolt adapters.

[0008] The connecting steel plate has an inner ring hole and an outer ring hole, which are equidistant from the center of the connecting steel plate.

[0009] Optionally, the connecting steel plate is a square plate-shaped structure with rounded corners.

[0010] Optionally, the inner ring hole corresponds to the connection hole at one end of the servo control system.

[0011] Optionally, the outer ring hole corresponds to the connecting hole at one end of the steel support, and one end of the outer ring hole is set as an inwardly recessed step, with its inward depth being greater than the thickness of the nut.

[0012] Optionally, the servo control system consists of a remote monitoring station, a field monitoring station, an operator station, and a field control station. The field control station is located near the edge of the foundation pit and is used to control five pump stations. Each pump station can control ten steel supports. Each station acquires data and sends control commands via a CAN bus.

[0013] Optionally, the on-site monitoring station can comprehensively monitor the real-time operation of all pump stations, including the pressure of each cylinder, the set pressure, the status of the pump station, the setting of operating parameters, the ability to collect and store operating data in real time, and the ability to display data in graphical form and print reports and export tables as required.

[0014] Optionally, the field control station has a real-time status monitoring function. It can collect field data by communicating with the underlying control unit and dynamically display information such as cylinder loading pressure, cylinder set pressure, and cylinder displacement in real time on the main interface in the form of numerical display or chart curve.

[0015] Optionally, the field control station has real-time control operation function. All cylinders and pump stations have selection function. After selecting the cylinder or pump station to be controlled, it can perform operations such as pressure upper limit compensation setting, pressure lower limit compensation setting, pressure upper limit alarm setting, pressure lower limit alarm setting, cylinder displacement upper limit alarm setting, cylinder displacement lower limit alarm setting, cylinder extension and retraction control, and automatic pressure control opening and closing control.

[0016] Optionally, a hydraulic support system is also included. This system mainly consists of a hydraulic power station, a remote monitoring console, a manual emergency operation box, communication cables, and a hydraulic support loading device. One hydraulic power station can simultaneously control 10 field cylinders to achieve compensation control of the axial force of 10 steel supports.

[0017] This invention provides a steel-supported servo system conversion device, which has the following beneficial effects:

[0018] This steel-supported servo system conversion device enables separate connection operations for both the servo system and the steel support structure on the same steel plate structure. This not only improves the support strength but also solves the problem of mismatch between the servo system and the steel support structure, thereby increasing the fault tolerance of the equipment.

[0019] Meanwhile, the servo control system features an automatic monitoring and compensation system with real-time monitoring, alarm, and automatic compensation functions for the supporting axial force. The system can dynamically adjust the axial force according to pre-set values ​​and upper and lower limits for each steel support. Specifically, when the measured axial force of the support is lower than the set lower limit, the system automatically activates to load the axial force of the target support to the set value, and vice versa. The system can also manually increase or decrease the axial force according to specific on-site requirements. Attached Figure Description
