Embodiment Construction

[0023] Such as figure 1 As shown, this embodiment includes a speed governor rope pulling mechanism, a left safety gear pulling mechanism, a right safety gear pulling mechanism, a left linkage mechanism and a right linkage mechanism. The above speed governor rope pulling mechanism, left safety gear pulling mechanism and right safety gear pulling mechanism are installed on the interconnected arc-shaped bottom plate 1 and arc-shaped side plate 6 inside the car frame, and the left safety gear pulling mechanism and the right safety gear pulling mechanism are distributed on the left and right sides of the speed governor rope pulling mechanism. The speed governor rope pulling mechanism is connected with the left safety gear lifting mechanism and the right safety gear lifting mechanism respectively by means of the left linkage mechanism and the right linkage mechanism, that is, when the speed governor is in action, it is pulled by the speed governor rope. The pulling mechanism synchr...

Abstract

The invention discloses a ring type safe plier connecting rod pulling mechanism which is suitable for ring type elevators. The ring type safe plier connecting rod pulling mechanism comprises a speed limiter rope dragging mechanism, a left safe plier pulling mechanism, a right safe plier pulling mechanism, a left linkage mechanism and a right linkage mechanism, the speed limiter rope dragging mechanism, the left safe plier pulling mechanism and the right safe plier pulling mechanism are installed on an arc-shaped bottom plate and an arc-shaped side plate which are mutually connected and arranged on the inner side of a lift car, the left safe plier pulling mechanism and the right safe plier pulling mechanism are distributed on the left and right sides of the speed limiter rope dragging mechanism respectively, the speed limiter rope dragging mechanism is respectively connected with the left safe plier pulling mechanism and the right safe plier pulling mechanism by the aid of the left linkage mechanism and the right linkage mechanism, namely, when the speed limiter is operated, by the aid of the left linkage mechanism and the right linkage mechanism, the speed limiter rope dragging mechanism synchronously drives the left safe plier pulling mechanism and the right safe plier pulling mechanism to perform pulling actions for corresponding safe pliers. The ring type safe plier connecting rod pulling mechanism has the advantages of being simple in structure, high in braking accuracy and good in reliability.

Description

technical field [0001] The invention belongs to the technical field of elevator safety, and relates to an elevator safety gear lifting mechanism, in particular to a ring type safety gear connecting rod lifting mechanism. Background technique [0002] The national standard GB7588 stipulates that safety gear must be provided for all passenger elevator cars that are pulled by rods or chains. Safety gear is a safety protection device for elevators, which is a mechanical device that can force the car to stop running when it overspeeds. Usually, the safety tongs are installed under the two ends of the lower beam of the car frame or in the inside of the vertical beam at the two ends of the lower beam. The speed limiter is a device that limits the speed of the car or counterweight. It is generally installed in the machine room or inside the elevator shaft, and its tensioning device is installed in the pit. [0003] The safety gear and speed limiter must be linked to brake the car....
