The invention provides a guardrail assembly, a working platform and a tower crane, the guardrail assembly comprises a fixed seat and a first guardrail unit, the first guardrail unit is provided with a connecting part, and the first guardrail unit is slidably connected with the fixed seat through the connecting part; when the connecting part moves to the unlocking position, the first guardrail unit has M degrees of freedom and can rotate around the connecting part relative to the fixed seat, and when the connecting part moves to the locking position, the first guardrail unit has N degrees of freedom and is limited by the fixed seat; m and N are positive integers, and M is greater than N. Through the arrangement, the first guardrail unit is always kept connected with the fixed seat, the first guardrail unit is controlled to enable the connecting part to be located at different positions on the fixed seat, so that the first guardrail unit is in different states, the purpose of convenient transportation can be achieved without dismounting, and the installation convenience is also improved; the problem that in the prior art, guardrails of an operation platform are disassembled and assembled repeatedly is solved.

    本申请提供了一种护栏组件、作业平台及塔机,护栏组件包括固定座与第一护栏单元,第一护栏单元设有连接部,且第一护栏单元通过连接部与固定座滑动连接;连接部移动至解锁位置时,第一护栏单元具有M个自由度,且第一护栏单元能够绕连接部相对于固定座转动,连接部移动至锁定位置时,第一护栏单元具有N个自由度,且第一护栏单元受固定座限位;M和N均为正整数,且M大于N。如此设置,第一护栏单元始终与固定座保持连接,通过操控第一护栏单元使连接部处于固定座上的不同位置,来令第一护栏单元处于不同的状态,不用拆除便可达到便于运输的目的,安装便利性也得到提高,解决了现有技术中作业平台的护栏反复拆装的问题。
