Telescopic crossing ladder
The invention discloses a telescopic crossing ladder. The telescopic crossing ladder comprises two groups of crossing vertical ladders, two groups of fixed fences and two groups of telescopic fences,wherein the crossing vertical ladders are of planar ladder structures, the fixed fences and the telescopic fences are of semicircular protective fence structures, and the crossing vertical ladders, the fixed fences and the telescopic fences are symmetrically arranged on the two sides of the truss; a plane structure crossing the vertical ladder, the fixed fence and the telescopic fence is fixed onthe truss, and the telescopic fence sleeves the fixed fence. The communication space of the truss is guaranteed by adopting the telescopic crossing ladder and the telescopic guardrail, and the safetyof the high-altitude crossing ladder is improved by adopting a fence type structure under the condition that the aisle space of the truss is not occupied; the structure is simple, manufacturing and operation are convenient, and manufacturing cost is low.
本发明公开了一种可伸缩式跨越梯，其中，所述可伸缩式跨越梯包括跨越直爬梯、固定围栏和伸缩围栏，跨越直爬梯为平面爬梯结构，固定围栏和伸缩围栏为半圆形防护围栏结构，跨越直爬梯、固定围栏和伸缩围栏均为两组，对称设置于桁架的两侧；跨越直爬梯、固定围栏和伸缩围栏的平面结构固定于桁架上，伸缩围栏套设在固定围栏外。本发明采用可伸缩式跨越梯利用可伸缩护栏既保证了桁架的通信空间，同时采用围栏式结构，在不占用桁架走道空间的情况下，提高了高空跨越梯的安全度；结构简单，制造、操作方便，制造成本低。
