Description

Anti-falling device for elevator

Technical Field

The invention relates to an elevator anti-falling device, in particular to an elevator anti-falling device which utilizes an anti-falling shielding door arranged in a door (a hall door and an outer door) of a passenger room to increase the stability of an elevator user taking the elevator.

Background

With the development of scientific and technological progress and urbanization, apartments and commercial buildings of various high floors have become the most common buildings in cities on the premise that the land can be effectively utilized and diversified uses are provided, and elevator devices in the buildings have become indispensable means of movement for the convenience of users to move to each floor.

Generally, an elevator apparatus employs a traction drive system, in which a traction machine installed on a top floor is used as a drive mechanism, a steel rope is suspended on the traction machine, one end of the steel rope suspends an elevator car, and the other end suspends a counterweight, and the traction machine and the steel rope generate traction force to drive the elevator car to move up and down by rotation of the traction machine.

However, at present, a common elevator only has one set of brake system, and is installed in a machine room of an elevator in the top floor of a building, and the circuit of the elevator is complex, the contacts of electrical parts are numerous, and as long as one electrical part contact is poor or fails, accidents of casualties are easily caused, and the accidents can be divided into two types, namely a first type: the personnel who take the elevator are passing in and out, and at this moment, elevator braking system is malfunctioning suddenly, no matter the elevator up or down move, to the personnel taking the elevator, all can cause great casualties accident, the second type: because the elevator brake system suddenly fails, the elevator car is not stopped at the appointed floor, when the elevator landing door (floor door) of the appointed floor is opened, the personnel taking the elevator can step empty without paying attention and fall into the bottom of the elevator shaft to cause serious casualty accidents.

All large elevator manufacturers at home and abroad actively seek solutions for casualties of elevator rushing and clamping people, but no mature technology is adopted by all the large elevator manufacturers so far, so that the casualties of elevator rushing and clamping people are smelled when being layered endlessly, for example, the invention patent certificate number TW I599533B (elevator anti-rushing method and structure) of Taiwan and the invention patent certificate number TW I614204B (elevator unexpected displacement instant braking protection device) of Taiwan are developed for solving the problem of elevator rushing, because the two technical schemes use a plurality of electronic elements, the more the relative parts are, the failure rate is relatively improved, the electronic elements are not easy to judge the quality of the elevator from the appearance, the regular maintenance is not easy to be realized, and if the elevator is met, the braking effect cannot be exerted, the invention has the advantages of simple structure, no use of electric power and no influence of power failure, and once the original brake fails, the elevator user can obtain the maximum safety guarantee when getting in and out of the elevator no matter the elevator car stops at any position of the elevator shaft.

In addition, in order to solve the problem of insufficient safety of the known elevator device, various manufacturers of elevators at home and abroad actively seek solutions for casualties of the elevator shaft caused by taking the elevator, but no mature technology is adopted by various manufacturers of elevators so far, so that the casualties of the elevator shaft are in endless and smelly, for example, the invention No. TWI 526390B (the ground entrance prevention device of a lifter) of Taiwan is a technical scheme developed for solving the casualties of the elevator shaft, although the invention device avoids the occurrence of the shaft casualties, the elevator maintenance personnel need to enter the elevator car for maintenance work due to the devices of the first grid-shaped belt and the second grid-shaped belt, and the invention device needs to reach the bottom of the elevator shaft for picking up small articles which fall down from a gap between a car door and a landing door carelessly, the invention is characterized in that a key, a bank card and the like are added, puzzles are increased, an elevator shaft cannot enter, the invention has no defect, furthermore, a traveling cable is arranged below an elevator car, a counterweight guide rail is arranged at the back, a car buffer is arranged at the bottom of an elevator pit, and a ladder stand is arranged on the wall of the bottom wall of the elevator pit, which are necessary equipment facilities of the elevator, because the space is limited, no matter the elevator is an existing elevator or a newly-arranged elevator, if a Chinese Taiwan patent certificate TW I526390B (an entering prevention device of a lifter) is added, the later maintenance work is difficult to carry out and cannot be carried out, but the invention arranges an anti-falling shielding door in the elevator door, applies a natural gravity rule, has simple structure, does not influence the later maintenance work, and an elevator user can obtain absolute safety guarantee.

Therefore, in order to solve the problem of insufficient safety of the known elevator device, the inventor of the present invention has conceived an elevator anti-falling device, which utilizes an anti-falling shielding door installed in a landing door (hall door, outer door) to increase the safety of the elevator user in using the elevator device, and several research experiments have completed the present invention.
