Abstract

The invention discloses a counterweight safety gear protection device which comprises a counterweight housing, an overspeed governor, a steel wire rope, two safety gear devices and a safety gear lifting device, wherein the counterweight housing moves up and down in a counterweight guide rail; the overspeed governor is arranged on a host fixing device above the counterweight guide rail and overlapped with the plumb bob direction of the counterweight housing, and the mounting height of the overspeed governor is consistent with the host mounting height; in the case of overspeed of the counterweight housing, the overspeed governor acts to stop the steel wire rope, and the steel wire rope acts on the safety gear devices on two sides of the counterweight housing through the safety gear lifting device so as to clamp the counterweight guide rail. The counterweight safety gear protection device disclosed by the invention has the advantages of simple structure, convenience and quickness in operation, space saving and safety and reliability.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a counterweight safety gear protection device. Background technique [0002] In the elevator, the counterweight device is an indispensable part of the vertical traction elevator, it can balance the weight of the car frame and part of the elevator load weight, and reduce the loss of motor power. However, when part of the shaft is in a space under the counterweight that people can reach, the counterweight must be equipped with a safety gear device to avoid potential safety hazards. The existing counterweight belt safety gear technology generally affects the size of the hoistway, resulting in higher construction costs for the hoistway. And the existing elevator can also rotate and drive the safety tongs to brake when the steel wire rope produces a small braking force, so the safety tongs malfunction and the safety performance is poor. Contents of the invention [0003] In orde...
