Foldable ladder stand for elevator pit
The foldable ladder stand comprises a ladder frame assembly, a plurality of folding structure assemblies arranged on the two sides of the ladder frame assembly and a safety switch assembly arranged on one of the folding structure assemblies. The ladder frame assembly comprises a handrail and a plurality of pedal rollers; the folding structure assembly comprises a connecting rod, a base, a first pin shaft and a second pin shaft. One end of the connecting rod is hinged to the outer side wall of the handrail through the first pin shaft, and the other end is hinged to the base through the second pin shaft. The safety switch assembly comprises a UKS switch, the UKS switch is fixed to the outer side wall of the base, an arc-shaped notch is formed in the edge of a second pin shaft, hinged to the base, of the connecting rod, and the trigger end of the UKS switch is arranged in the arc-shaped notch. The device can be folded, does not interfere with a landing door sill, and can adapt to most elevators with door opening sizes and shaft sizes; a UKS switch is arranged, so that the safety performance is good; the scheme is good in executability, and the original shaft arrangement is not influenced; the structure and the processing technology are simple.
本发明是一种可折叠式电梯底坑爬梯，包括梯框组件、设置在梯框组件两侧的若干个折叠结构组件以及设置在其中一个折叠结构组件上的安全开关组件；梯框组件包括扶手以及若干个踏辊；折叠结构组件包括连杆、底座、第一销轴和第二销轴，连杆一端通过第一销轴与扶手外侧壁铰接且另外一端通过第二销轴与底座铰接；安全开关组件包括UKS开关，UKS开关固定在底座的外侧壁上，连杆与底座铰接的第二销轴边缘处设有弧形缺口，UKS开关的触发端头设置在弧形缺口内。本发明可以折叠不会与层门地坎干涉，能适应绝大部分开门尺寸和井道尺寸的电梯；配备UKS开关，安全性能好；方案可执行性好，不影响原有井道布置；结构和加工工艺简单。
