Fall-prevention safe fire-fighting equipment for high-rise elevator

Abstract

The invention relates to the field of elevator fire protection, in particular to fall-prevention safe fire-fighting equipment for a high-rise elevator. The fall-prevention safe fire-fighting equipmentcomprises an elevator lift car and an elevator shaft, a trigger block is movably installed in the elevator shaft, a limit device is movably installed below the trigger block, the two ends of the limit device are arranged to be in diamond shapes, and the two ends of the limit device and a fixing device are arranged to be in an oblique acute angle triangle shape, so that when the limit device rotates to limit the elevator lift car, the fixing device can be triggered to move upwards through a slope, and the two sides of the elevator lift car are accordingly clamped and fixed; then the right sideof the rhombic lower end of the limit device is arranged in an inwards-sinking manner, and a meshing groove where a meshing protrusion block arranged below the fixing device is embedded is arranged,so that the efficiency that the limit device drives the fixing device to move upwards is improved; and through fixing protrusion blocks, opposite to wholly-wavy zigzag grooves fixedly connected to oneside of the elevator lift car, of the fixing device, and the fixing efficiency of the elevator lift car is improved after contact with the elevator lift car.

Description

technical field [0001] The invention relates to the field of elevator fire protection, in particular to a fall prevention safety fire protection device for high-rise elevators. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific higher floors in the building, and its car runs on at least two rigid rails perpendicular to the horizontal plane or with an inclination angle of less than 15° from the plumb line. In case of failure, the elevator fire lock will limit and fix it in time to ensure the safety of internal personnel. [0003] However, most of the existing elevator fire locks are tightened by the steel cable when the elevator falls so that the clamping rails on both sides are fixed, but when the steel cable breaks or the limit device of the steel cable breaks down and cannot be fixed, it cannot be fixed. The elevator is limited and fixed. Contents of the invention [0004] A fall-prevention safety fire-f...
