Crawling ladder for meter look-up
The invention discloses a crawling ladder for meter look-up. The crawling ladder comprises two uprights which are in left-right corresponding arrangement, multiple cross beams which are in up-down mutual parallel are fixedly connected between the left upright and the right upright, through penetrating holes which are in left-right corresponding arrangement are formed in each cross beam, a pressing rod is jointly inserted in the penetrating holes on the same side penetratingly in an up-down moving manner, multiple pedaling rods which are in up-down mutual parallel are fixedly connected between the pressing rod and the right pressing rod, the pedaling rods and the cross beams are arranged at intervals, the lower end of each pressing rod is hinged to an antiskid disc, and the lower surface of each antiskid disc is not higher than the lower end of the corresponding upright after the corresponding pedaling rod is stepped down. Each antiskid disc can move up and down and can make contact with the ground after the corresponding pedaling rod is stepped down, so that backward sliding of the lower end of the crawling ladder is prevented effectively, and safety of meter reading personnel is guaranteed. By the crawling ladder, the meter reading personnel can complete meter look-up work independently without assistance of others, so that surplus labor force is freed, and working efficiency is improved.
