Embodiment Construction

[0011] First, install a set of blocking buffer devices to prevent the elevator car from squatting on the well walls on both sides of the car between the first floor and the second floor or on the car guide rails in the elevator shaft. The rope pulley and the arresting rope are placed horizontally on the reverse rope pulley, and the two ends are connected to the arresting counterweight below, and the arresting counterweight is installed in the cylindrical guide rail, and the car arresting hook is installed on both sides of the car.

[0012] The combined weight of all blocking counterweights should not exceed two-thirds of the weight of the car. The principle is that when the car falls at high speed, the car blocking hook hooks the blocking cable and continues to run downward, and the blocking cable is dragged upward by the anti-rope pulley The reaction force generated by the counterweight is dragged to offset part of the momentum of the car's falling, which plays a role in decel...

Abstract

In order to solve the car collapsing accident caused by sliding out-of-control of an elevator, the invention discloses a blocking buffering device for preventing the elevator car from collapsing. Theblocking buffering device comprises a blocking cable, diversion sheaves, blocking counterweights and car blocking hooks, wherein the car blocking hooks hook the blocking cable for dragging and blocking to achieve the car deceleration. The specific embodiment mode comprises the steps that firstly, a blocking buffering device for preventing the elevator car from collapsing is mounted on each shaft wall of the two sides of the car or each guide rail of the car from a first layer to a second layer in an elevator shaft, the two diversion sheaves are mounted in the horizontal direction of each device, the blocking cable is horizontally placed on the diversion sheaves, the two ends of the blocking cable are connected with the blocking counterweights below, the blocking counterweights are mountedin the cylindrical guide rails, and the car blocking hooks are mounted on the two side surfaces of the car; and the total weight of all the blocking counterweights cannot exceed two third of the car weight, the principle of the blocking buffering device for preventing the elevator car from collapsing is that when the car falls at a high speed, the car blocking hooks hook the blocking cable to continue to operate downwards, and counterforce generated through the mode the blocking cable drag the blocking counterweights upwards through the diversion sheaves counteract a part of impact force of falling of the car, so that the deceleration effect is achieved.

Description

Technical field: [0001] The invention relates to the field of traction-driven elevator mechanical safety devices, in particular to a blocking and buffering device for preventing an elevator car from squatting. Background technique: [0002] With the continuous development of modern society, there are more and more factories and mines, buildings are getting higher and higher, and the installation and use of elevators are becoming more and more popular. Elevators have become high-risk mechanical equipment. There are many personal injury accidents in elevator accidents, so The safety of elevator operation cannot be ignored. Among them, the elevator car is out of control and the squatting accident caused by rapid sliding is the most serious, and the existing buffer stroke is too short to effectively reduce the damage caused by the accident. The present invention greatly reduces the damage caused by this type of accident. Invention content: [0003] In order to solve the car s...
