Hidden turnover ladder and oil field operation equipment

Abstract

The invention relates to a hidden turnover ladder. The hidden turnover ladder is characterized by comprising an upper ladder assembly and a lower ladder assembly, wherein the upper ladder assembly comprises a baseplate, and a pair of mounting vertical plates symmetrically arranged on the baseplate; multiple stages of upper antiskid pedals are arranged between the mounting vertical plate; first pin shaft holes are formed in the lower front parts of the mounting vertical plates; the lower ladder assembly comprises a pair of step type mounting side plates; connecting lug plates are arranged at the upper ends of the mounting side plates, and are rotationally connected with the first pin shaft holes through first pin shafts; and multiple stages of lower antiskid pedals are arranged between the mounting side plates. The hidden turnover ladder has the beneficial effects of less occupied space, convenience for use and folding capacity in no use. The invention further discloses oil field operation equipment adopting the turnover ladder; and the oil field operation equipment has the following beneficial effects: second pin shafts are arranged for connecting a car body with the hidden turnover ladder, so that the turnover ladder can be accommodated in a turnover ladder accommodating cavity after two times of overturning, and the effect of convenience for use and transportation is achieved.

Description
