Described articulated joints is at least 2.
Described articulated joints is hinge.
Described vertical direction locking device A is identical with the scantling of structure of vertical direction locking device B.
Described vertical direction locking device A and vertical direction locking device B is installed in the side of nonfloating rail.
Described horizontal direction locking device A is identical with the scantling of structure of horizontal direction locking device B.
The beneficial effects of the utility model: the utility model is arranged on crane in bridge type, when crane in bridge type normally works, Telescopic guardrail can be subdued, locked with horizontal direction locking device, and then rotational vertical direction locking device, put down by folding guard rail, the height of whole like this guardrail is just the same with the height of nonfloating rail, can utilize factory building by actv.; When hoisting crane needs to safeguard, during maintenance, hoisting crane can be parked in the higher position of factory building, then by folding guard rail pull-up, locked with vertical direction locking device, make it keep vertical, and then open horizontal direction locking device, Telescopic guardrail ejects, and the height of guardrail can reach the demand of protection personal safety; The utility model is easy to use, simple to operate, reasonable in design, and actv. protects personal safety and make use of factory building efficiently, avoids causing unnecessary waste.
