Abstract

A safety plier automatic triggering mechanism for a telescopic elevator mounting platform comprises a movable part, a fixed part, a spring, a transverse rod part and a triggering movable part; the fixed part is fixed to a portal frame upper beam of an elevator, the movable part is fixed to a hoister, the transverse rod part is fixed to the portal frame upper beam through a shaft part, and the twoends of the spring abut against the upper portion of the fixed part and the lower portion of the movable part; one end of the triggering movable part is hinged to the lower portion of the movable part, and the other end of the triggering movable part is fixed to the transverse rod part; the end part of the transverse rod part is connected with a pulling plate of a safety plier through a connectingpiece; and when elevator rapid weightlessness occurs, a spring pushes away the movable part to enable the movable part to be away from the fixed part, the movable part drives the triggering movable part to rotate around the transverse rod part to drive the transverse rod part to rotate, and the transverse rod part pulls the pull plate when rotating. The safety plier automatic triggering mechanismis simple in structure and convenient to install, and automatic triggering can be achieved without manual intervention. Stepless adjustment can be carried out in the length direction, and the safetyplier automatic triggering mechanism is particularly suitable for the telescopic elevator mounting platform.

Description

technical field [0001] The invention relates to the technical field of elevator installation based on an adjustable telescopic elevator platform, in particular to an automatic safety gear trigger mechanism for a telescopic elevator installation platform. Background technique [0002] In recent years, the elevator installation technology has gradually transitioned from scaffolding construction to non-scaffolding construction technology, and the special elevator platform has also been more and more widely used. Commonly used elevator platforms generally use safety locks and safety gears as safety components, and safety gears are commonly used as safety guarantees for elevators, which are generally indispensable. The trigger method of the safety gear is mainly triggered by the elevator speed limiter. It is inconvenient to install the speed limiter on site in advance, and it is not suitable for this field. Another form of trigger mechanism used by domestic elevator installation...
