Abstract

The invention relates to a double-action safety gear lifting mechanism. The double-action safety gear lifting mechanism comprises a first elevator double-action safety gear, a second elevator double-action safety gear, a first brake rod, a second brake rod, a lifting rod, a balance beam and a rope end connecting rod, wherein the first elevator double-action safety gear and the second elevator double-action safety gear are in left-right symmetry, one end of the first brake rod is inserted into the first elevator double-action safety gear, the other end of the first brake rod is rotatable connection with one end of the balance beam, one end of the second brake rod is inserted into the second elevator double-action safety gear, the other end of the second brake rod is in rotatable connection with the other end of the balance beam, one end of the lifting rod is rotatably connected with the middle of the balance beam, and the other end of the lifting rod is connected with one end, arranged on the lateral side of the second elevator double-action safety gear, of the rope end connecting rod. The double-action safety gear lifting mechanism is simple in structure, low in manufacturing cost and high in cost performance.

Description

technical field [0001] The invention relates to the technical field of elevator operation safety devices, in particular to a bidirectional safety gear lifting mechanism. Background technique [0002] When the elevator runs overspeed, it will trigger the action of the speed limiter. The wire rope of the speed limiter will make the safety gear move through the safety gear pulling mechanism, and the elevator car will stop after the safety gear moves. The existing safety gear lifting mechanism mostly uses the rotation of the shaft to drive the crank to rotate so as to drive the lifting rod to lift up, and the safety gear pulls to stop the car. This kind of lifting mechanism has a complicated structure and high manufacturing cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bidirectional safety gear lifting mechanism with simple structure, low manufacturing cost and high cost performance. [0004] The technical...
