Elevator safety braking device

Abstract

The invention discloses an elevator safety braking device. The elevator safety braking device comprises an elevator shaft wall, a lifting rail, an elevator car, a rail brake, safety airbag boxes, a rail hanging lug baffle, an airtight bulkhead, a buffer plate, buffer columns, communicating holes, sealing valves, an airtight buffer bin, a buffer bin communicating pipe, a communicating pipe sealingplug, a sealing plug spring, a sealing plug triggering ejector rod, a bearing plate, an elevator traction machine, a traction steel wire rope, a steel wire rope monitor, and an elevator car distance sensor; the sealing plug triggering ejector rod is arranged in the lifting rail at the bottom end of the elevator shaft wall; the top end of the sealing plug triggering ejector rod is abutted against the rail hanging lug baffle arranged in the lifting rail; the rail hanging lug baffle is located at an early warning height; the safety air bag boxes are arranged at the bottom end of an elevator car;the airtight bulkhead is arranged at the bottom end of the elevator shaft wall, and the airtight bulkhead is installed in the lifting rail through the edge; and the buffer plate is mounted above the airtight bulkhead through the buffer columns. The elevator safety braking device has the characteristics of multiple buffering and mild and stable braking.

Description

technical field [0001] The invention relates to an elevator safety braking device, in particular to an elevator safety braking device with multiple buffers and gentle and stable braking. Background technique [0002] With the development of modern industry, elevators, as a means of transportation, are more and more closely connected with our lives. While elevators bring convenience to people, their failures also directly threaten people's lives. The elevator braking device is especially important as the safety guarantee of the elevator. [0003] The current elevator brakes generally have an overly complex structure, slow braking response, and insufficient traction of the speed-limiting sheave, resulting in insufficient clamping force, inability to brake quickly, inaccurate speed measurement, abnormal braking, and abnormal fall of the elevator car. , causing injury and damage to the elevator equipment and passengers.
