Elevator car type elevator landing door device

Abstract

The invention relates to an elevator car type elevator landing door device. The elevator car type elevator landing door device comprises an upper sill frame, a landing door hanging plate, a door hanging wheel, a pressing wheel and a door lock device installed on the upper sill frame. The pressing wheel is fixed to the landing door hanging plate. The elevator car type elevator landing door device is characterized in that the upper sill frame is of an integrally extrusion-formed structure and comprises an upper section part and a guide rail extending downwards from the upper section part; the guide rail is in a transversely-placed S shape; a vertical extension section extends downwards from the guide rail, and the head of the vertical extension section is folded upwards, so that a guide edge and a folded edge are formed. According to the structural design of the elevator car type elevator landing door device, the upper sill frame structure is applied to an elevator car type elevator landing door, the door hanging wheel is connected with the guide rail in a hung mode, a protruding part of the guide edge is connected with the pressing wheel, and thus a rolling track of the pressing wheel is limited; the technical problem that an existing landing door device is poor in use safety performance is solved, and the stability of the elevator car type elevator landing door is improved.

Description

technical field [0001] The invention relates to a landing door device in the field of elevators, in particular to a car-type elevator landing door device. Background technique [0002] At present, car-type elevators have been used in large areas in my country. The main component of the car-type elevator is the door lock device. The main function of the door lock device is to ensure that the car door locks when Can not be opened, and the parts that make up the door lock device are installed on the upper sill of the car, and the landing door device has also embraced the landing door hanging plate, door hanging wheel and pressure roller. [0003] There are technical defects in the commonly used upper sill structure: the guide rails on the upper sill are basically solid guide rails or spliced ​​and welded guide rails. In the production process, not only are there many process steps, but also waste materials, increasing the overall upper sill The weight of the upper sill leads to...

Problems solved by technology

[0003] There are technical defects in the commonly used upper sill structure: the guide rails on the upper sill are basically solid guide rails or spliced ​​and welded guide rails. In the production process, not only are there many process steps, but also waste materials, increasing the overall upper sill The weight of the upper sill leads to instability when the upper sill is installed; the authorized announcement number is CN203306893U, and its authorized patent number is 201320398687. The parallel side of the end of the part is connected with the pressure roller. In actual use, because the pressure roller is constantly rotating, not only will it easily cause shaking, but also cause the end of the guide rail to wear, so that the pressure roller cannot work normally and damage the whole. Elevators pose a safety hazard
