The invention discloses a safety system of an elevator shaft. The safety system of the elevator shaft comprises an inductor, a telescopic component and a controller, wherein the inductor is arranged at the bottom of the elevator shaft; the inductor is connected with the controller; the telescopic component is fixedly arranged at the bottom of the elevator shaft, and comprises a telescopic post which is made from a magnet or a magnetisable material, and a coil which drives the telescopic post to move up and down and can be electrified; the telescopic post is arranged in a mounting hole arranged in the bottom of the telescopic post; the coil which can be electrified is arranged outside the telescopic post in a sleeving manner and is fixed relative to the mounting hole. The safety system can monitor whether a foreign object makes an incursion into the elevator or not in real time; when the foreign object makes the incursion, the coil which can be electrified is enabled to bounce under the control of the controller, a safe region is provided for the foreign object making the incursion, and the foreign object making the incursion is prevented from being extruded and having a safety accident.
Description
technical field [0001] The invention relates to the technical field of elevator equipment, in particular to an elevator shaft safety system. Background technique [0002] A sufficient safety space needs to be set up at the top and bottom of the elevator shaft, which is also called a machine room-less elevator. Sufficient top and bottom space provide protection for maintenance personnel to repair, and can also provide security for illegal intruders, such as preventing being crushed by the elevator shaft. [0003] In the existing life, the bottom of the elevator shaft is generally provided with fixed grooves to prevent illegal intruders from being pressed by the elevator box, but the space of the elevator shaft is wasted in this way. This protective space should be normally used when there is no illegal intrusion, and its maximum utilization value should be exerted. Therefore, a new technology is needed to improve the existing safety equipment. Contents of the invention ...
