Lifting anti-falling device
The invention relates to the technical field of lifting devices, in particular to a lifting anti-falling device which comprises a lifting module and a limiting module, the lifting module comprises a lifting body and a lower protruding part, the lower protruding part is arranged on the lifting body in a protruding mode, and a plurality of tooth grooves arranged up and down are formed in the portion, on one side of the lower protruding part, of the lifting body; the limiting module comprises a shifting piece and a retainer, the shifting piece is rotatably arranged on the side, away from the lifting body, of the tooth groove, and the retainer is arranged on the outer side of the shifting piece; in the ascending process of the lifting body, the shifting piece is movably inserted into the tooth groove to prevent the lifting body from moving downwards; the shifting piece is provided with a first contact part, the retainer is provided with a first retaining part, when the lifting body ascends to a specified height, the shifting piece can be shifted upwards by the lower convex part, so that the first contact part is aligned to the first retaining part and is inserted by the first retaining part, the shifting piece is locked, and in the locking state, the shifting piece is separated from the tooth groove, and the locking part is locked. The lifting body can move downwards.
本发明涉及升降装置的技术领域，具体涉及一种升降防坠装置，包括升降模块和限位模块，升降模块包括升降本体和下凸起部，下凸起部凸设在升降本体上，升降本体在下凸起部的一侧设有若干个上下排列的齿槽；限位模块包括拨动件和止动件，拨动件可转动地设在齿槽背离升降本体的一侧，止动件设在拨动件的外侧；在升降本体的上升过程中，拨动件用于活动地插接于齿槽以阻止升降本体下移；拨动件设有第一接触部，止动件设有第一止动部，当升降本体上升到指定高度时，下凸起部能够将拨动件往上拨动，以使得第一接触部对准于第一止动部并被第一止动部插接，从而将拨动件锁定，在该锁定状态下，拨动件脱离于齿槽，升降本体能够下移。
