Safety elevator capable of effectively avoiding falling into shaft

Abstract

The invention relates to a safety elevator capable of effectively avoiding falling into a shaft. The safety elevator comprises the elevator shaft, two fixing mechanisms and a speed reducing mechanism, each fixing mechanism comprises a connecting block, an electromagnet is fixedly installed on the outer surface of each connecting block, four cross rods are fixedly installed in an inner cavity of each connecting block, and four electric telescopic rods are fixedly mounted in an inner cavity of each connecting block. According to the safety elevator capable of effectively avoiding falling into the shaft, the fixing mechanisms are connected to the left side and the right side of an elevator body through connecting columns, when the elevator decelerates to a certain speed and moves to fixing grooves formed in the front surface and the rear surface of a vertical plate, the fixing mechanisms work, two fixing plates in the fixing mechanisms move out of inner cavities of the fixing mechanisms and are inserted into the fixing grooves, springs play a role of buffering, when the fixing plates and buffer blocks move to the groove bottoms of the fixing grooves, due to limiting of the fixing grooves, the elevator body cannot continue to move downwards, and meanwhile, the electromagnet and the vertical plate attract each other, so that the auxiliary fixing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a safe elevator that can effectively avoid falling into a well. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or less than 15° from the plumb line. Modern elevators are mainly composed of traction machines. (Winch), guide rail, counterweight device, safety device (such as speed limiter, safety gear and buffer, etc.), signal control system, car and hall door, etc. These parts are respectively installed in the shaft and machine room of the building . [0003] Due to the convenience and comfort of the elevator, it is widely used in high-altitude buildings, but when the desired elevator is used, accidents often occur. [0004] Elevators occasionally break down during operation, and the worst case...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a safe elevator that can effectively avoid falling into a well, which has the advantages of multiple deceleration and fixing the elevator, and solves the problem that the existing elevator has only one deceleration mode and cannot be used when it fails. The elevator slows down and cannot be fixed, and the problem of falling may follow
