Elevator car anti-falling device capable of avoiding falling stall

Abstract

The invention discloses an elevator car anti-falling device capable of avoiding falling stall, and particularly relates to the field of elevators. The elevator car anti-falling device comprises a main body mechanism, wherein the two sides of the main body mechanism are provided with brake mechanisms used for controlling the moving speed of the main body mechanism, a buffer mechanism used for cushioning is arranged at the bottom of the main body mechanism, the main body mechanism comprises a hoistway, supporting rails are fixedly installed at the four corners of the hoistway, rectangular gear blocks are fixedly installed on the inner walls of the supporting rails, a lift car is arranged in the hoistway, a balancing frame used for controlling the moving balance of the lift car is fixedly installed on the outer wall of the lift car, and a traction machine used for being connected with the balancing frame is fixedly installed at the top of the hoistway. According to the invention, brake sleeves used for being clamped to the outer walls of gear columns are arranged on the two sides of the lift car, friction resistance during rotation of the gear columns is increased, so that the rotation speed of the gear columns is controlled to be slowly adjusted, the lift car is driven to slowly fall till stopping, and the actual use is more facilitated.

Description

technical field [0001] The invention relates to the technical field of elevators, and more specifically, the invention relates to an elevator car fall prevention device for avoiding falling and stalling. 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 at an inclination angle of less than 15° from the plumb line. [0003] At present, some elevators drive the elevator car to move by pulling the traction machine rope. However, when the rope breaks, the elevator car will definitely crash. Because the traditional measure for the falling elevator is the deceleration of the pulley , its anti-falling effect is not obvious enough, which is not conducive to practical use. Contents of the invention [0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the pres...
