Description

Anti-riot rushing device for elevator

The invention relates to an elevator anti-rushing device, in particular to an elevator anti-rushing device which uses brake guide rails and brake modules to increase the stability of elevator users riding the elevator.

With the advancement of technology and urbanization, under the premise of effective land use and diversified uses, various high-rise apartments and commercial buildings have become the most common buildings in the city, and in order to facilitate users Moving to each floor, the elevator device in the building becomes an indispensable means of movement.

Generally speaking, the elevator device adopts the traction drive method, the traction machine installed on the top floor is used as the driving mechanism, and the steel rope is hung on the traction machine, and the steel rope is suspended at one end of the elevator car and the other end is suspended. The weight, through the rotation of the traction machine, causes the traction machine and the steel rope to produce a traction force to drive the elevator car up and down.

However, at present, general elevators have only one set of brake and braking system, and are installed in the elevator machine room on the top floor of the building. Its wiring is complicated, and there are many electrical parts contacts. As long as there is an electrical part contact with poor contact or failure, it is easy to cause Accidents involving casualties can be divided into two categories. The first category: people taking the elevator are entering and exiting. At this time, the brake system of the elevator suddenly fails, regardless of whether the elevator is moving up or down. , Will cause serious casualties, the second category: due to the sudden failure of the elevator brake system, the elevator car has not stopped at the designated floor, when the designated floor elevator door (landing door) is opened, the person taking the elevator If you don’t pay attention, you will step on the air and fall into the bottom of the elevator shaft, causing serious casualties. The invention of this case can avoid such accidents and protect the safety of human life and property.

Elevator manufacturers at home and abroad are actively working to find solutions for elevator crashes and casualties, but as of now, no mature technology has been adopted by major elevator manufacturers, so elevators storm There have been many casualties involving people, such as invention patent certificate number TW I599533B (elevator anti-burst method and its structure), invention patent certificate number TW I614204B (instant brake protection device for elevator unexpected displacement), yes In order to solve the technical solution developed by the elevator storm, because the two technical solutions use multiple electronic components, the more the number of parts, the higher the failure rate, and the electronic components are generally not easy to judge from the appearance. Regular maintenance is also not easy to detect. If there is a power failure, the braking effect of the brake cannot be exerted and there is a potential safety hazard. The invention has a simple creation structure, no power is used, and is not affected by the power failure. Once the original brake fails, regardless of the elevator car, When parked at any position of the elevator shaft, elevator users can get the maximum safety guarantee when entering and exiting the elevator.

In addition, there are accompanying cables under the elevator car, counterweight guide rail behind, car buffer at the bottom of the elevator pit, and ladder at the bottom wall of the pit. These are necessary equipment for the elevator. Due to limited space, no matter whether it is an existing elevator or a newly installed elevator, if you want to install the invention patent certificate number TW I526390B (entrance prevention device of the elevator), it will be difficult to carry out future maintenance and repair work. However, the present invention is to install an anti-fall shield door in the passenger door, using the natural law of gravity, the structure is simple, does not affect the future maintenance work, elevator users can obtain absolute safety guarantee.
