The invention discloses an elevator safety gear integrated lifting mechanism. The elevator safety gear integrated lifting mechanism comprises an underneath type lifting mechanism, an electric trigger device and two safety gears, wherein each safety gear is provided with a side plate, a lifting rod and a movable wedge block, one ends of the lifting rods are fixedly connected with rotating shafts, the rotating shafts penetrate through and are rotationally arranged on the side plates, the other ends of the lifting rods abut against the wedge blocks. the underneath type lifting mechanism comprises a short rod, a long rod, a linkage rod and a driving spring which are located outside the safety gears, the rotating shaft on one safety gear is fixedly connected with the long rod, one end of the long rod and one end of the short rod are rotationally connected with the two ends of the linkage rod, the other end of the short rod is fixedly connected with the rotating shaft on the other safety gear, the other end of the long rod is connected with the electric triggering device, the linkage rod is sleeved with a driving spring, one end of the driving spring is fixedly connected with the linkage rod, and the other end of the driving spring is fixedly connected with the safety gears connected with the long rod. The elevator safety gear integrated lifting mechanism is fast in action response, simple in structure and convenient to maintain.
Description
technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator safety gear integrated lifting mechanism. Background technique [0002] At present, the lifting brake system is realized by using an integrated safety lifting mechanism and a speed limiter to pull the wire rope. The use of this structure can save space in the well and optimize the configuration of the well. However, during the pulling action of the safety gear, due to the transmission between the internal parts of the speed limiter, there is a gap, the number of parts and the transmission distance. Empty position can easily lead to a relatively slow response speed of the lifting safety gear, resulting in adverse effects such as untimely lifting and misoperation, and the existing integrated safety lifting mechanism has a large number of related parts due to the cooperation with the traditional speed limiter , especially not conducive to cost reduction, and this stru...
