Portable crawling ladder for maintenance of fire-fighting equipment

Abstract

The invention discloses a portable crawling ladder for maintenance of fire-fighting equipment. The portable crawling ladder comprises inclined frame plates, pedals, stop parts, transverse frame plates, a standing platform, a rear support frame, moving wheels, a connecting bottom plate, control buttons, a storage battery, a power line and a telescopic platform device. The telescopic platform deviceis mounted at the bottom of the standing platform, a left telescopic platform and a right telescopic platform are enabled to extend outwards under pushing of a telescopic pushing mechanism, then thestanding area of the standing platform can be increased, the time-consuming and labor-consuming problems caused by the fact that the crawling ladder is required to be moved back and forth manually during maintaining are solved, and the maintenance efficiency is increased; meanwhile, by means of the telescopic pushing mechanism, the left telescopic platform and the right telescopic platform can beretracted into a platform storage box, no space is occupied, furthermore, an auxiliary supporting device is used for supporting the left telescopic platform and the right telescopic platform, therefore, a standing person keeps stable conveniently, and safety is improved.

Problems solved by technology

[0003] In the firefighting work, various firefighting equipment are often used, including short and small firefighting equipment, and tall and large firefighting equipment, such as fire engines, cranes, etc. After a long period of use, firefighting equipment needs to be repaired to ensure follow-up For normal use, when large-scale fire-fighting equipment needs to be repaired, the height of the maintenance personnel is usually increased by means of a ladder to facilitate maintenance of the equipment. The existing ladder is usually a single standing platform, and the standing platform space is small, while the fire-fighting equipment The perimeter is large, and it is usually necessary to move the ladder back and forth during maintenance, and then re-up the ladder for maintenance, which is very troublesome and greatly affects the efficiency of maintenance
