A foldable multifunctional steel structure ladder

Abstract

The invention discloses a foldable multifunctional steel structure ladder comprising a first ladder column and a second ladder column. Movable connection device and a detachable connection bar deviceare arranged between the first ladder column and the second ladder column; the outer side wall of the first ladder column is provided with a portable tool transport device, and the outer side wall ofthe second ladder column is provided with a detachable moving wheel device; the movable connection devices are composed of rectangular grooves, fixed frames, and a cross connecting rod assembly, and the detachable connection bar device is composed of fixed seats, a rectangular neck, a threaded through hole, a connecting rod, a positioning round hole, and a set screw; the portable tool transport device is composed of a T-shaped slide slot, a T-shaped sliding block, a hook, transmission shafts, rollers, a steel wire, a rotary table, and operating rods; and the detachable moving wheel device is composed of fixed columns, hollow supporting columns, screw holes, screws, nuts, moving wheels, and cushioning springs. The foldable multifunctional steel structure ladder has the beneficial effects ofsimple structure and high practicability.

Description

technical field [0001] The invention relates to the field of steel structure ladders, in particular to a foldable multifunctional steel structure ladder. Background technique [0002] Steel structures have the characteristics of light weight, high strength, good ductility, and strong seismic performance. We often see steel structure ladders in construction sites and other places. Traditional steel structure ladders have simple structures, but single functions, which can no longer meet the needs of today's society. When the ladder is not in use, the size of the ladder itself is too large, resulting in too much floor space; during the transfer process of the ladder, the weight of the ladder will cause certain problems to the workers; and when the workers are using it, the ladder is too high The reason is that it is inconvenient for workers to take tools, so a foldable multifunctional steel structure ladder is needed now. When the ladder is not in use, it can be folded to reduc...

[0002] Steel structures have the characteristics of light weight, high strength, good ductility, and strong seismic performance. We often see steel structure ladders in construction sites and other places. Traditional steel structure ladders have simple structures, but single functions, which can no longer meet the needs of today's society. When the ladder is not in use, the size of the ladder itself is too large, resulting in too much floor space; during the transfer process of the ladder, the weight of the ladder will cause certain problems to the workers; and when the workers are using it, the ladder is too high The reason is that it is inconvenient for workers to take tools, so a foldable multifunctional steel structure ladder is needed now. When the ladder is not in use, it can be folded to reduce the floor space of the ladder. The convenient tool transport device provided can It is convenient for workers to take tools while using the ladder. The detachable moving wheel device can facilitate workers to move the ladder, which greatly reduces the burden on workers. This kind of steel structure ladder is not only simple in structure, but also has multiple functions.
