Abstract

The invention provides a hanging ladder used for street-cross overpass maintenance. The hanging ladder comprises rubber mats, thin nuts and a guardrail. Four universal wheels are arranged, provided with brakes and connected and fixed to the bottom side of a sliding board through bolts. Two hanging rings are arranged, one hanging ring is welded to the top side of a balancing weight at the upmost end, and the other hanging ring is welded to the left side face of a hanging arm. Butterfly bolts are fixed to the right ends of fixing chucks. Press heads are rubber products and are arranged on the left sides of the butterfly bolts. The rubber mats are arranged on the left side faces in the fixing chucks and used for increasing the contact friction force. The thin nuts are connected to the butterfly bolts and located on the right sides of the fixing chucks. The hanging ladder is limited and fixed through the guardrail, meanwhile, the balancing weight is arranged as assistance, the stability ofthe hanging ladder can be effectively enhanced, meanwhile, due to the fact that the hanging arm is moved conveniently, in the working process, the fixing chuck at the corresponding end can be released so that displacement of the hanging arm can be conducted in the direction, and position is convenient to adjust.

Description

Technical field [0001] The invention belongs to the technical field of hanging ladder structures, and in particular relates to a hanging ladder used for maintenance of overpasses. Background technique [0002] Overpass is a kind of building that assists pedestrians to cross the road in modern cities. The construction of overpass can completely separate pedestrians and vehicles on the road, ensuring smooth traffic and safety of pedestrians. Many cities set up advertising spaces on overpasses. , Installation and removal or maintenance are more difficult. [0003] For example, the application number CN201720072313.7 discloses a safety hanging ladder for building construction, including an upper hanging ladder, a lower hanging ladder and a safety belt. The upper hanging ladder includes two supporting rods arranged in parallel with each other. There are multiple step rods arranged in parallel, the upper hanging ladder is set on the top of the lower hanging ladder, and the upper hanging...
