An elevator safety braking device

Abstract

The invention discloses an elevator safety braking device, which comprises an elevator shaft wall, a lifting rail, an elevator car, a rail brake, a safety airbag box, a rail hanging lug baffle, an airtight partition, a buffer plate, a buffer column, and a communication hole , sealing valve, airtight buffer chamber, buffer chamber connecting pipe, connecting pipe sealing plug, sealing plug spring, sealing plug triggering the ejector rod, load-bearing plate, elevator traction machine, traction wire rope, wire rope monitor, elevator car distance sensor device; the lifting rail at the bottom of the elevator shaft wall is provided with a sealing plug to trigger the ejector rod, and the top of the sealing plug triggers the ejector rod against the track hanging lug baffle provided in the lifting track, and the track hanging lug baffle is located at the warning height; The bottom end of the elevator car is provided with an airbag box; the bottom end of the elevator shaft wall is provided with an airtight partition, and the airtight partition is installed in the lifting track through the edge; a buffer column is installed above the airtight partition plate. The invention has the characteristics of multiple buffering and gentle 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.
