Elevator having anti-falling function

Abstract

The invention provides an elevator having an anti-falling function. The elevator comprises a car, a lifting device and limiting rails, wherein the lifting device is connected with the car; the car is provided with an accommodating tank; an anti-falling device is arranged in the accommodating tank, and comprises a centrifugal limiting rod and a spring; the centrifugal limiting rod is rotationally arranged in the accommodating tank; one end of the spring is connected with the car, and the other end is connected with the centrifugal limiting rod; and the limiting rails are arranged at the two sides of the car, and are provided with multiple limiting clamping grooves fitting the centrifugal limiting rod. The elevator adopts a pure mechanical principle, so that the structure is simple, safe and reliable, the manufacturing cost is low, a greater effect on the prevention of personal and object harm caused by sudden out-of-control falling of the elevator is achieved, and a greater protection effect on the daily life of common people and the production of enterprises and public institutions is achieved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator with a fall prevention function. Background technique [0002] Most of the existing safety devices for preventing elevators from falling use electronic components, which are easy to cause misoperation, misjudgment, and have a limited service life, especially when the elevator is running when the power is suddenly cut off, the electronic components will not be able to play a role , It is very easy to fall because of loss of control, which not only causes damage to articles, but also easily causes personal casualties, causing great losses to people's daily life and the production of enterprises and institutions. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an elevator with a purely mechanical principle, simple structure, safety, reliability, low cost and anti-fall function based on the deficiencies of t...
