Embodiment 1

[0027] Such as figure 1 with image 3 As shown, a stair with a transformable form includes a step 1 and a support frame 2 for supporting the step 1. The step 1 is provided with multiple layers from top to bottom, and a crossbeam 3 is arranged inside the support frame 2, and the crossbeam 3 corresponds to the steps 1 one by one, the crossbeams 3 are distributed symmetrically front and back, and respectively correspond to the inner walls on the left and right sides of the step 1, the steps 1 and the crossbeams 3 are slidingly connected by a pair of guide rail sliders, and the rear end of the supporting frame 2 is provided with a drive The first cylinder 4 that moves forward and backward on the step 1, the first cylinder 4 corresponds to the step 1 one by one, the first cylinder 4 is symmetrically distributed front and back, the cylinder end of the first cylinder 4 is hinged with the front end of the support frame 2, and the piston of the first cylinder 4 The rod end is hinged w...

Embodiment 2

[0035] Such as Figure 4 As shown, the step 1 is fixedly connected to the beam 3, the width of the rotating plate 5 is the same as the surface width of the step 1, the rear end of the rotating plate 5 is directly connected to the step by rotation, the rear end of the rotating plate 5 is provided with a sleeve, and the rotating shaft passes through The sleeve at the rear end of the rotating plate 5 is connected to the inner side of the step. The rotating plate 5 can rotate around the rotating shaft. The lower end of the first connecting plate 9 is provided with a third cylinder 12, and the cylinder end of the third cylinder 12 is hinged with the first connecting plate 9. , the piston rod end of the third cylinder 12 is hinged with the end plate 7, the third cylinder 12 drives the end plate 7 to rotate counterclockwise, and then the second cylinder 6 drives the rotating plate 5 to rotate clockwise, and the upper and lower rotating plates 5 are spliced ​​into a slope.

Abstract

The invention discloses a staircase with changeable forms. The staircase comprises steps and a supporting frame used for supporting the steps; cross beams are arranged in the supporting frame and correspond to the steps in a one-to-one mode; rotating plates are arranged at the front ends of the upper surfaces of the steps; second air cylinders for driving the rotating plates to rotate are arranged at the front ends of the steps; end plates are arranged on the front end faces of the steps; and the lower ends of the end plates are rotationally connected with the steps. In a normal use state, the shape of the staircase is the same as that of an existing staircase, when a person with disability needs to climb the staircase on a wheelchair, the second air cylinder drives the rotating plates to rotate, the rotating plates on all the layers are spliced into a slope shape, the person with disability can conveniently go up and down on the wheelchair, and safety and reliability are achieved; and in the forward moving process of the steps, the end plates rotate anticlockwise along with the steps, and rotation of the rotating plates cannot be interfered.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a staircase with transformable forms. Background technique [0002] Stairs are an architectural design used to connect large vertical distances, for communication between floors and when there is a large difference in height. [0003] Most of the existing stairs are stairs of reinforced concrete structure or steel structure. The structure of this kind of stairs is fixed. For the disabled, it is difficult to climb the stairs and they are easy to roll down. Contents of the invention [0004] The object of the present invention is to solve the above-mentioned problems, and provide a stair with a changeable form, which can change the form of the staircase, and is convenient for the disabled to go up and down in a wheelchair. [0005] The technical scheme that the present invention solves its technical problem to take is: [0006] A stair with a transformable shap...
