The invention discloses a working platform guardrail locking mechanism. The locking mechanism comprises a plurality of pairs of locking positions which are arranged on a main supporting guardrail and a side guardrail and matched with one another, each pair of locking positions comprises a shaft hole formed in the main supporting guardrail and a pin hole formed in the side guardrail, an operation plate and a connecting plate are connected in the shaft hole through a pin shaft, a U-shaped lock pin can be connected in the pin hole in series, and the operation plate and the connecting plate are installed on the U-shaped lock pin, so that the main supporting guardrail and the side guardrail can be locked. The locking mechanism has the advantages that the structure is very compact, operation and use are easy and convenient, rapid folding and recovery of the platform folding guardrail can be achieved, gaps between the folding guardrails are reduced, and therefore the overall height of the folded guardrail is reduced, the trafficability of the whole machine is improved, and the purpose of rapid transition is achieved.
本发明公开了一种工作平台护栏锁紧机构。它包括主撑护栏和侧面护栏上设置的相互配合的多对锁定位,每对锁定位均包括一个设置在主撑护栏上的轴孔和一个设置在侧面护栏上的销孔,轴孔中通过一根销轴连接有一个操作板和一个连接板,销孔中能够串接有U型锁销,通过将操作板和连接板安装在U型锁销上能够将主撑护栏和侧面护栏进行锁定。优点在于:其结构十分紧凑、操作使用简单方便,可实现平台折叠护栏的快速折叠、恢复,并缩减折叠护栏间间隙,从而降低了护栏折叠后的整体高度,提高了整机通过性,实现快速转场的目的。
