One end of the locking pin 136 is inserted into the pin hole 137 with clearance fit, and the other end extends into the mounting cavity 135 and is fixedly sleeved with the limit plate 138. One end of the cable 133 passes through the second through hole and is fixedly connected to the locking pin 136, and the other end is connected to the side of the guardrail unit 1 away from the mounting frame 131. A support spring 139 is disposed in the mounting cavity 135 between the locking pin 136 and the second through hole.

[0041] In this embodiment, before pulling out the guardrail 12, an operator pulls the two adjacent cables 133 to make the locking pins 136 on both sides of the guardrail 12 come out of the pin holes 137 respectively. At this time, another operator can pull the guardrail 12 out of the plug-in seat 11. The disassembly is convenient and the locking is stable, avoiding the impact of the guardrail 12 on the hoisting of the workpiece.

[0042] In a preferred embodiment, such as Figure 2 As shown, a guard plate 14 is fixedly installed on the inner side of the cable 133 on the guardrail unit 1 to prevent maintenance personnel from accidentally kicking the cable 133 when walking on the maintenance platform, which could cause the cable 133 to break or the interlocking component 13 to mis-lock, thus providing good protection.
