Description

Technical Field

[0001] The present invention relates to the technical field of lifting devices, in particular to a lifting device for steps of a convertible barrier-free escalator. Background Art

[0002] Barrier-free escalators can not only transport normal passengers in the usual escalator mode, but can also be switched to wheelchair-only operation via a wheelchair operation switch. A specific step system will be widened along the longitudinal direction of the escalator through a lifting device to maintain a horizontal level. Wheelchairs of specified sizes, electric tricycles, and electric four-wheeled vehicles can be transported. After a certain period of time, ordinary passengers are allowed to enter. They can be installed outdoors. This type of escalator not only saves transportation time, but also provides convenience for people with disabilities who have difficulty walking.

[0003] The traditional lifting device only has the function of lifting up and down. During the operation of the steps, the stopping position may deviate due to factors such as wear, resulting in a deviation between the stopping position of the steps and the lifting device, which is not conducive to the connection between the lifting device and the steps.

[0004] For example: China Invention Patent Application: CN202022005313.X, the disclosed "barrier-free escalator", its specification discloses: by adjusting the height of the scissors mechanism 700 and thus adjusting the height of the lifting panel 300, during the rising process of the barrier-free escalator 100, the scissors mechanism 700 applies different forces to the lifting panels 300 at different heights, so that the lifting panels 300 rise at different speeds, so that the lifting panels 300 at different steps 101 are always located at the same horizontal plane, providing a fixed platform for passengers...; the above patents can prove the defects of the existing technology.

[0005] Therefore, we make improvements to this and propose a lifting device for the steps of a conversion-type barrier-free escalator. Summary of the Invention
