However, traditional inverted arch trestle hydraulic control systems typically use a centralized control method. This means that the control valve groups of all hydraulic actuators are centrally located in a control cabinet and connected to each actuator via hydraulic piping. This control method has the following disadvantages:

[0003] Complex hydraulic pipelines, difficult installation and maintenance: Centralized control requires laying a large number of hydraulic pipelines, resulting in a complex system structure, difficult installation and maintenance, and high costs;

[0050] Working principle: Step 1: When in use, an instruction is sent to the central control unit 2 through an external connection device. The central control unit 2 receives the operation instruction and sensor feedback signal, performs logical operations and control decisions, generates a control signal and sends it to the corresponding distributed electro-hydraulic control unit; the distributed control unit 21 receives the control signal, controls the action of the electro-hydraulic proportional valve or the switch valve, and each driving unit on the surface of the inverted trestle equipment 1 receives the instruction and operates;

[0051] Step 2: When the pouring trolley 12 is running, the driving motor 5 is started. The driving motor 5 drives the driving screw 52 to rotate through the transmission mechanism 51. The threaded sleeve 53 moves on the surface of the driving screw 52 under the action of the push plate 54 and the driving screw 52. The push plate 54 pulls one end of the airbag 4 to extend.
