Abstract
The invention discloses a suspension bridge type anti-climbing ladder. According to the suspension bridge type anti-climbing ladder, a building is provided with a fixed ladder provided with stairs; the lower part of the fixed ladder is provided with a movable ladder; the lower part of the movable ladder is connected to a stay rope passing through a pulley. The movable ladder is connected to the fixed ladder for use; and when the suspension bridge type anti-climbing ladder is not used, the movable ladder is pulled upward so as to prevent irrelevant personnel from climbing.
Description
Technical field
The present invention relates to a kind of use only for maintenance personal prevent up and down other personnel at risks climbing can pull-up the anti-climbing ladder of suspension bridge type.
Background technology
At present, architectural being provided with of high chimney, viaduct contour level in factory can supply the upper and lower ladder of maintenance personal, although this ladder has facilitated building maintenance repairman, but usually because ladder is a kind of open state all the time, the top that these personnel that go to extremes that just make some cause because of variety of issue also can climb up highrise building along ladder is with the threat mutually of committing suicide, to society, brought destabilizing factor, if can be by not used time sealing, disconnection of ladder, just can not gone to extremes personnel with opportunity, be reduced social destabilizing factor.
Summary of the invention
In order to solve the problem of above-mentioned proposition, the invention provides the anti-climbing ladder of a kind of suspension bridge type, the anti-climbing ladder of this suspension bridge type, the used time connects, not used time pull-up, effectively prevents unrelated person climbing.
The object of the present invention is achieved like this, the anti-climbing ladder of suspension bridge type, the fixed ladder that band ladder is stepped on is housed on building, fixed ladder is connecting mobile ladder below, the lower end of mobile ladder is connected with the stay cord through pulley, during use, after the work such as maintenance of ascending a height complete, upwards pull stay cord that mobile ladder pull-up is hung and both can avoid idler to climb building.
Feature of the present invention is, adopted bottom one section at ordinary times can pull-up foldingly lock, the used time puts down connected design, flexible, safe and reliable.
Accompanying drawing explanation
Figure is structural representation of the present invention.
In figure: 1, building; 2, fixed ladder; 3, mobile ladder; 4, stay cord; 5, pulley; 6, ladder is stepped on.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
In view, band ladder is housed on building 1 and steps on 6 fixed ladder 2, fixed ladder 2 is connecting mobile ladder 3 below, the lower end of mobile ladder 3 is connected with the stay cord 4 through pulley 5, during use, after the work such as maintenance of ascending a height complete, upwards pull stay cord 4 that mobile ladder 3 pull-ups are hung and both can avoid idler to climb building.
