Pedal anti-falling protection device used for moving walk

Abstract

The invention discloses a pedal anti-falling protection device used for a moving walk. The device comprises a sliding rail support matched with the arc part of a tensioning trolley, a sliding rail arranged on the side, close to the tensioning trolley, of the sliding rail support, and a connecting part used for connecting the sliding rail support with the tensioning trolley; the sliding rail, the tensioning trolley and the connecting part form space at least allowing a part of pedal assembly to pass through; according to the pedal anti-falling protection device used for the moving walk, the sliding rail support matched with the arc part of the tensioning trolley is arranged, a pedal is supported and guided, when a pedal connecting block between the pedal and a pedal chain falls off, the relative position between the pedal and the pedal chain is ensured, the pedal can smoothly pass through the rotation end, the condition that the pedal falls off, and a person is hurt or equipment is damaged is avoided, a sliding rail is arranged to avoid rigid contact between the pedal and the sliding rail support, and the damage and the noise generated by the device can be avoided.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a pedal fall-off prevention protection device for moving walks. Background technique [0002] With the rapid development of the economy, more and more large supermarkets have entered people's lives. In order to better serve customers, large supermarkets are generally equipped with moving walkways. The pedals of the moving walk are generally connected to the pedal chain through the pedal connecting block. Due to long-term use or insufficient maintenance, the pedal connecting block may become loose or even fall off, resulting in the separation of the pedal and the pedal chain. However, due to the structure of the sidewalk itself, only when the pedal enters the turning end, will the pedal be detached from the pedal chain and fall to the inside of the truss due to its own gravity.

AI Technical Summary

Problems solved by technology

The pedals of the moving walk are generally connected to the pedal chain through the pedal connecting block. Due to long-term use or insufficient maintenance, the pedal connecting block may become loose or even fall off, resulting in the separation of the pedal and the pedal chain.

However, due to the structure of the sidewalk itself, only when the pedal enters the turning end, will the pedal be detached from the pedal chain and fall to the inside of the truss due to its own gravity. If a passenger takes a ladder or a shopping cart passes by at this time, it is easy to cause the passenger's foot to fall to the inside of the moving walkway or the shopping cart gets stuck inside the sidewalk, causing safety issues such as casualties or equipment damage
