Door machine left slow door slide plate assembly

Abstract

The invention aims to provide a door machine left slow door slide plate assembly, and particularly relates to an elevator quick and slow door safety linkage structure and a safety system correspondingthe elevator quick and slow door safety linkage structure. The linkage structure is arranged between an elevator quick door and an elevator slow door, and accordingly, the situation that safety accidents occur due to the fact that the slow door is opened when the quick door is not opened is avoided. According to the door machine left slow door slide plate assembly, faults caused by door closing and faults during power operation are not prone to occurring, in addition, passengers determine a stepped pulley door, a platform and a lift car according to the switch position of the lift car, LED lamps are installed on the bottom face of an entrance of the lift car and can be turned on and off, thus, elevator using safety accidents can be prevented, and the aesthetic feeling is realized.

Description

technical field [0001] The invention relates to a linkage structure of fast and slow doors of an elevator, in particular to a sliding plate assembly of the left slow door of a door machine. Background technique [0002] As we all know, the elevator door has an irreplaceable role in the components of the elevator. The elevator door mainly plays the role of closing the elevator space for safety protection. The elevator door is generally divided into two types: the opposite movement type and the fast and slow door opening in the same direction. Way. [0003] For the structure with fast and slow doors opening in the same direction, it includes a shutter and a slow door. When working, the shutter and the slow door open or close in the same direction. [0004] As far as the fast and slow door structures appearing on the market are concerned, the shutter and the slow door are slid and set in the slide rail on the top of the elevator, and the shutter and the slow door are connected...

AI Technical Summary

Problems solved by technology

[0005] In the slow door swing link connecting plate of the general elevator door opener system provided by the prior art, such as: it is reinforced with a steel plate with a thickness of 8mm, a length of 195mm, and a width of 135mm, and a flat iron with a thickness of 10, a width of 50, and a length of 135; its manufacturing process The process is oxygen cutting into a prototype, and then grinding with a grinding wheel, drilling with a drilling machine, welding with an electric welding machine, and then using a milling machine or lathe to mill out two semicircles with a length of 35mm, a width of 11mm, and two edges punched into 11mm. The center of the two holes is For holes with a distance of 80mm, the processing time is more than 4 times longer than that of the new model in this example; the upper end is two holes with a fixed diameter of 15mm, which is not convenient for installation and debugging

Therefore, the slow door swing link connecting plate of the existing general-purpose elevator door opener system is bulky, has poor practicability, wastes materials, is not conducive to processing, manufacturing and installation, and has a high overall cost, which is not conducive to the development and application of elevators.

However, in specific applications, it often happens that the interlocking relationship between the shutter and the slow door is destroyed when the interlocking pull rope exceeds its service life or is accidentally damaged and disconnected, thus causing a safety accident. When the moving pull rope is accidentally damaged and disconnected, the shutter and the slow door cannot be opened or closed synchronously. When the shutter is still closed, the slow door has already been opened. At this moment, the elevator in operation cannot be closed, resulting in a large potential safety hazards, and this is the main shortcoming of traditional technology
