[0002] At present, most of the working platform guardrails of scissor-type aerial work platforms are folding guardrails, which need to be locked when the guardrails are erected. In the current industry, most of the guardrails are welded with U-shaped bent plates and locked with lock pins or pin shafts. However, Since the scissor-type aerial work platform needs to fold the guardrail of the working platform during the transportation process or when the transition process is limited by the height of the door, the existing guardrail welding U-shaped bending plate with the lock of the lock pin or pin shaft The U-shaped curved plate of the tight mechanism will occupy the overall height of the platform after the guardrail is folded after the guardrail is folded, which may cause poor passability or impassability

Embodiment Construction
[0018] The working platform guardrail locking mechanism of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] As shown in the figure, the working platform guardrail locking mechanism of the present invention includes multiple pairs of locking positions that cooperate with each other provided on the main guardrail 1 and the side guardrail 2, wherein the main guardrail 1 includes a front guardrail and a back guardrail, and multiple pairs of locking positions The positions include a pair of locking positions formed between the front guardrail and the right side guardrail 2, a pair of locking positions formed between the front guardrail and the left side guardrail 2, and a pair of locking positions formed between the back guardrail and the right side guardrail 2. Locking position, a pair of locking positions formed between the back guardrail and the left side guardrail 2, each pair of lock...

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.
