Abstract

The invention relates to the field of elevator safety protection, in particular to an anti-drop protection device used for vertical elevator ascending and descending. The anti-drop protection device used for vertical elevator ascending and descending comprises a wire rope, a car and an anti-drop protection device body installed on the car. The anti-drop protection device body comprises a verticalframe vertically fixed to the top face of the car; an anti-drop clamping board of an annular structure is fixedly arranged in the middle of the vertical frame and symmetrically provided with clampingsleeves; a rotation mechanism is arranged at the center of the anti-drop clamping board and comprises a rotation disc installed on the inner side of a ring hole of the anti-drop clamping board; a spiral rod is vertically and fixedly arranged at the geometric center of the rotation disc; two pull ropes of the same structure are arranged on the surface of the spiral rod; the upper and lower ends ofthe two pull ropes are in an X shape and connected with the lower surface of a cross beam and the top face of the car separately; and the anti-drop protection device body further comprises an anti-drop block. The anti-drop protection device used for vertical elevator ascending and descending is simple in structure, convenient to maintain, stable in working state, safe and reliable.

Description

technical field [0001] The invention relates to the field of elevator safety protection, in particular to an anti-drop protection device for vertical elevator lifting. Background technique [0002] Elevators are widely used in various multi-storey buildings. According to their movement mode, they can be divided into vertical lifting type, step type and crawler type. Modern elevators greatly facilitate people's lives and improve people's travel efficiency. Among them, vertical elevators are mainly used in multi-storey buildings to take people or carry goods. It is composed of traction machine (winch), guide rail, counterweight device, safety device (such as speed limiter, safety gear and buffer, etc.), signal control System, car and hall door etc. During the running process, the traction machine lifts the car vertically through the flexible wire rope, so as to realize the passenger or load. [0003] With the extension of the service life of the elevator, daily management, ...
