Safety anti-disengagement structure applied to elevator landing door

Abstract

The invention discloses a safety anti-disengagement structure applied to an elevator landing door, and relates to the technical field of elevator parts. The safety anti-disengagement structure comprises a base plate and a door plank, the door plank is arranged below the base plate, a positioning plate is arranged on the front face of the base plate, a cover plate is arranged above the positioningplate, limiting plates are arranged on the two sides of the cover plate, a partition plate is arranged in the middle of the base plate, and a driving motor is fixedly installed on the upper surface ofthe partition plate; the output end of the driving motor is in transmission connection with a transmission rod; the positioning plate, the cover plate and the limiting plates are buckled on the frontface of the base plate; the positioning plate corresponds to the joint between the lower end of the base plate and the door plank, the cover plate corresponds to the installation position of the driving motor at the upper end of the base plate, the limiting plates correspond to a winch, when the landing door structure breaks down, partial disassembling can be conducted according to the fault without disassembling the whole outer plate structure, and the overhaul time is saved; and meanwhile, the mounting structures of the positioning plate, the cover plate and the limiting plates are simple,and the convenience of disassembling the outer plate structure of the elevator landing door is improved.

Description

technical field [0001] The invention relates to the technical field of elevator parts, in particular to a safety anti-detachment structure applied to elevator landing doors. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical lift has a car that runs between at least two vertical columns of rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical transportation in buildings regardless of its driving mode. [0003] 1.

AI Technical Summary

Problems solved by technology

[0003] 1. In the existing technology, the top of the elevator landing door is mostly fixed by hanging, and it is directly turned secretly at the lower end of the driving mechanism. After long-term use, the equipment is aging, which will easily lead to loose suspension structure, causing the landing door to fall, and the driving is always large. Security risks;

[0004] 2. In the prior art, the elevator landing door hanging installation structure is relatively complicated, and the outer plate structure is interlocking, making disassembly and assembly difficult, which brings inconvenience to the local inspection and maintenance of the elevator
