Abstract

The invention relates to the technical field of elevators, in particular to a high-sensitivity escalator handrail belt inlet safety protection device. The high-sensitivity escalator handrail belt inlet safety protection device comprises inlet rubber, a baffle and a safety switch. The baffle is fixed to an escalator truss, the inlet rubber is located on the front side of the baffle, and the safety switch is located on the rear side of the baffle; gap-shaped openings are formed in two corners at the bottom and two cross sections on the upper middle portion of an inlet of the inlet rubber, communicated specially-shaped holes are formed in the lip portion of the inlet of the inlet rubber, a flexible steel wire rope is arranged in the specially-shaped holes, one end of the steel wire rope is fixedly connected to the baffle, and the other end of the steel wire rope is connected with a triggering mechanism of the safety switch. The safety protective device has the advantages that micro-deformation of the lip portion of the inlet rubber is used for triggering the safety switch, sensitivity is effectively improved, damage is reduced or avoided, dangerous conditions on the two sides and the bottom of a handrail belt inlet are effectively eliminated, and practicality is good.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a high-sensitivity escalator handrail entrance safety protection device. Background technique [0002] The escalator handrail entrance safety protection device is an important protection device for the safe riding of the escalator, such as figure 1 As shown, the prior art escalator handrail mouth safety protection device mainly includes an entrance rubber, a baffle and a safety switch, the entrance rubber is installed on the front side of the baffle and is provided with a handrail mouth, and a There is a safety switch, and the handrail is set outside the mouth of the handrail. The entrance rubber, baffle and safety switch are all installed on the escalator truss, the entrance rubber and the baffle are fixedly connected, and under the action of external force, the baffle can move towards the direction of the safety switch and trigger the safety switch. Under normal circumstanc...
