[0036] A plurality of telescopic railings 14 are fixedly connected to one side opposite to the two transverse plates 11 , and the telescopic railings 14 are used to protect the area on the one side opposite to the two transverse plates 11 .

[0037] The horizontal plate 11 includes a middle plate body 111 and two plate bodies 112. The two plate bodies 112 are respectively installed at the two ends of the plate body 111 through shaft rotation, and the shaft connections at both ends of the plate body 111 are symmetrically distributed along the transverse center line.

When disassembling the lifting guardrail main body 1, the fastening bolt can be removed to fold the lifting guardrail main body 1.

[0039] Through the use of wires by those skilled in the art, all electrical components in this case are connected to their corresponding power supplies, and appropriate controllers should be selected for electrical connection with the driver 13 according to actual conditions to meet control requirements. For specific connections and control sequences, reference should be made to the following working principle, in which the electrical components are electrically connected in a sequential working order. The detailed connection methods are well-known technologies in this field. The following mainly introduces the working principles and processes, and does not explain the electrical control.

[0040] Working principle: When in use, assemble the lifting guardrail body 1, pass the lower connecting ring 54 through the vertical tube 3 until it rests against the lower limit ring 52, and pass the upper connecting ring 53 through the connecting rod 4 until it rests against the upper limit ring 51, and then connect the threaded cap 55 to the connecting rod 4 to limit and fix the lifting guardrail body 1 to prevent the lifting guardrail body 1 from falling off, and then assemble the lifting guardrail body 1 with the vertical tube 3 on the base 2, and the number of lifting guardrail bodies 1 and base 2 can be increased and assembled according to needs, so as to adjust the overall length of the lifting guardrail module.

[0041] The actuator 13 drives the threaded telescopic rod to rotate, adjusting the distance between the two horizontal plates 11, thereby controlling the overall height of the lifting guardrail body 1 and achieving the lifting function. Since the upper horizontal plate 11 is connected to the connecting rod 4, the lifting and lowering of the horizontal plate 11 simultaneously drives the connecting rod 4 up and down, thereby supporting both ends of the upper horizontal plate 11 through the cooperation of the connecting rod 4 and the vertical cylinder 3.

[0042] The rotatable second plate 112 allows the lifting guardrail body 1 to be folded and unfolded, saving space and facilitating storage and transportation. When assembling the lifting guardrail body 1, the second plate 112 is rotated to align with the first plate 111. The locking bolt 115 is then passed through the connection hole 114 and connected to the locking nut 116, securing the second plate 112 to the first plate 111, thereby keeping the lifting guardrail body 1 unfolded. To disassemble the lifting guardrail body 1, the fastening bolts can be removed to fold the lifting guardrail body 1.
