Stairway for constructional engineering based on worm wheel and worm

Abstract

The invention belongs to the technical field of stairways, and particularly relates to a stairway for constructional engineering based on a worm wheel and a worm. The stairway comprises stairway pedals, telescopic baffles, adjusting mechanisms, and stairway side plates. The two adjusting mechanisms are respectively installed in the two stairway side plates. The four stairway pedals are respectively installed at the position between the two stairway side plates through cooperation with the two adjusting mechanisms. One telescopic baffle is respectively installed between at the position every two neighboring stairway pedals in the four stairway pedals. In a normal state of the designed stairway, the stairway pedals are positioned in a horizontal state, under this situation, the stairway canbe used as a normal stairway. While the disabled sitting in a wheelchair wants to climb the stairway, the multiple stairway pedals are enabled to form a smooth slope through regulating swing of the stairway pedals. People can push the wheelchair to walk on the smooth slope, so the wheelchair passes through the stairway smoothly, and the stairway has the better using effect.

Description

Technical field [0001] The invention belongs to the technical field of stairs, in particular to a staircase used in construction engineering based on worm gears. Background technique [0002] Stairs are an essential facility in multi-storey buildings. At present, the stairs mainly include cement steps, wooden steps, or metal steps, etc., but no matter what kind of stairs, they are all ladder-like steps. There are limitations. When going up and down the stairs, pedestrians can only go up or down step by step. This is perfectly fine for people with normal health, but for people with inconvenient lower limbs, they use wheelchairs instead of walking. In this way, it is impossible to go up and down the stairs. Even normal people, when they are dragging items such as luggage carts or bags, it is more laborious to go up and down the stairs of this step type; Stairs for walking are very necessary. [0003] The present invention designs a kind of staircase that is used in construct...
