Rotatable lift car toe guard

Abstract

The invention relates to a rotatable lift car toe guard, solving the problem that the retractable toe guard in the prior art is easy to be damaged upon collision with the ground and possibly cannot be returned in place. The lift car toe guard comprises an upper toe guard piece and a lower toe guard piece articulated to each other, wherein a stop rod mechanism rotating along with the downward movement of the lift is arranged on the upper toe guard piece; a cam coaxially connected with the stop rod mechanism is further arranged on the upper toe guard piece; and a link mechanism capable of pulling the lower toe guard piece for turnover along with the rotation of the cam is arranged on the cam. The design of the stop rod mechanism, the cam and the link mechanism of the toe guard provided by the invention realizes transformation from rotation to linear movement so that the toe guard rotates at a certain angle; in this way, the demand for the depth of the foundation pit is reduced; the toe guard does not need to collide with the ground surface of the foundation pit; and damage on the toe guard and accidental harm on people are avoided.

Description

[0001] technical field [0002] The invention relates to an elevator device, in particular to a rotatable car toe guard that meets the requirements of a shallow pit and prevents the toe guard from colliding with the ground of the pit. Background technique [0003] Elevator car toe guards are designed to prevent hall door passengers from being cut by the descending car door frame when stretching their feet. It is very necessary. Generally, toe guards are installed on elevator cars. The toe guard is generally fixed on the front side of the bracket of the car sill. According to the standard for the toe guard, the width of the toe guard should be equal to the entire clear width of the landing entrance, and the height of the vertical part should be at least 0.75m. extending downwards. [0004] The existing car toe guards are generally vertical steel plates with bends at the bottom, and the car toe guards are directly installed in front of the sill bracket at the bottom of the ca...
