Abstract

The invention discloses a push-pull type welcome pedal of an elevator and belongs to elevator safety devices. The push-pull type welcome pedal of the elevator comprises a pedal 1, a pedal 2, guide rails 3, guide rails 4, pulleys 5 and fixing pieces 6, and is characterized in that the pulleys 5 are mounted at two ends of each of the pedal 1 and the pedal 2; the guide rails 3 comprise an upper-layer guide rail 3 and a lower-layer guide rail 3, and the pedal 1 is mounted on the upper-layer guide rail 3; the guide rails 4 comprise an upper-layer guide rail 4 and a lower-layer guide rail 4, and the pedal 2 is mounted on the lower-layer guide rail 4; the fixing pieces 6 are mounted at two ends of each of the guide rails 3 and the guide rails 4. The guide rails and cross rods are adopted for double supports to guarantee stability of the welcome pedal, a double-insurance safety protection function is realized, and the problem of safety accidents caused by pedal loosening when passengers take the elevator is solved.

Description

technical field [0001] The invention relates to an elevator push-pull welcome pedal. Background technique [0002] The structural design of the welcoming pedals of existing escalators or moving walks is unreasonable, and loose screws will cause the pedals to collapse, which is prone to safety accidents of personal injury and death. For example, the patent application number is 201220036069.6—comb-tooth pedal for elevators, which is a pedal assembled from multiple iron plates. Although the manufacturing process is simple and saves raw materials, it lacks safety. [0003] For example, at around 10:00 am on July 26, 2015, an elevator safety accident occurred in the Anliang Department Store in Jingzhou, Hubei. A 30-year-old woman was thrown into the escalator and died on the spot. According to the on-site investigation, the cause of the accident was that the welcome pedal of the elevator was loose, causing the pedal to collapse after the passenger stepped on it and was involved...
