Durability experiment device for door lock of construction hoist

Abstract

The invention discloses a durability experiment device for a door lock of a construction hoist, and the device comprises a bottom plate, wherein the upper surface of the bottom plate is movably connected with a lifting device, the top of the lifting device is provided with a lifting plate, and the upper surface of the lifting plate is slidably connected with a side plate. The invention relates to the technical field of lock testing. According to the device, through arrangement of the lifting device, when the device is in use, a driving wheel drives a screw rod to rotate, an X-shaped rod is extruded and deformed under the limitation of an adjusting device; after the device reaches a designated position, the adjusting device is separated from the screw rod, a lifting plate stops moving, and a cam is driven by the screw rod to continue to rotate; the connecting rod is influenced by the cam to drive the lifting plate to move up and down, and the lifting plate is directly influenced by the screw, so the lifting plate can perform high-frequency and low-frequency shaking in the vertical direction at the moment, the shaking range is larger, more experimental data can be acquired, and the problem that the experimental variety and range of a traditional lock are smaller is solved.

Description

technical field [0001] The invention relates to the technical field of lock testing, in particular to an experimental device for the durability of construction elevator door locks. Background technique [0002] The construction hoist adopts door lock devices of different structures to be used in cage doors, fence doors, landing doors and other components, and is equipped with electrical interlock devices. Every switch action of the door lock device during the up and down operation of the construction hoist will touch the mechanical and electrical components of the door lock device, requiring the door lock device to have sufficient strength and durability. For safety reasons, the construction elevator door lock device needs to be tested for durability before leaving the factory to detect the reliability of the mechanical and electrical components of the door lock device. [0003] Most of the traditional construction elevator door locks only perform repeated opening and closi...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a construction elevator door lock durability experiment device, which solves the problem that the lock cannot simulate the connection with the door frame, the reciprocating motion in the vertical direction cannot accurately detect the overall safety of the elevator, and, Experimental equipment is affected by the size and model of the lock, and it is a relatively single and fixed problem
