The invention discloses a crawling ladder with a foot bar interval adjusting function. The crawling ladder comprises a crawling ladder body; the two sides of the crawling ladder body are provided with fixed handrailings, a groove is formed in the handrailing face of the inner side of each handrailing and provided with a plurality of holes, and a plurality of pushing and plugging columns are guided into the positions, corresponding to the grooves, of the outer portions of the handrailings; a plurality of foot bars are installed between the grooves, a plurality of hydraulic supporting retractable rods are vertically connected between the foot bars, and the two ends of each foot bar are separately provided with spring type latches; and the two ends of the foot bars abut against the grooves to slide through the spring type latches. By adoption of the mode, the crawling ladder with the foot bar interval adjusting function can freely adjust the interval between the foot bars of the crawling ladder to be adapted to different working requirements and different personnel using requirements.
Description
technical field [0001] The invention relates to the field of climbing ladders, in particular to a climbing ladder equipped with adjustable step bar spacing. Background technique [0002] The ladder is a tool used for climbing. There are no guardrails on both sides of the ladder. Any two points can bear twice the weight of the human body. Each rung must be able to bear the weight of the human body. The distance and materials are all stipulated. There may be fixed back rings or no fixed back rings, and a rest platform must be required above a certain height. Temporary ladders have no guardrails and must have a 4-fold insurance factor. However, the traditional ladder structure is fixed, and the ladder rods cannot be adjusted according to the needs. It is not possible to increase the distance between the climbing rods when working at low altitudes to improve climbing efficiency, and it is also impossible to adjust the distance between the climbing rods when working at high alti...
