Escalator with anti-turnover function on leading edge treads

Abstract

The invention discloses an escalator with a front-edge pedal having a rollover prevention function and belongs to the technical field of escalators. The escalator comprises a truss, a rear-edge pedal, a comb plate and a front-edge pedal, wherein a left longitudinal beam of the truss is fixed at the upper part of the left side of the truss; a right longitudinal beam of the truss is fixed at the upper part of the right side of the truss; a left shelf bar is fixed at the left end of the left longitudinal beam of the truss; a right shelf bar is fixed at the left end of the right longitudinal beam of the truss; the left end of the rear-edge pedal is shelved on the left shelf bar; the right end of the rear-edge pedal is shelved on the right shelf bar; the upper part of the front side of the comb plate forms a front-edge pedal shelving groove; the left end of the front side of the front-edge pedal is shelved on the left shelf bar; the right end of the front side of the front-edge pedal is shelved on the right shelf bar; the edge part on the rear side of the front-edge pedal is shelved in the front-edge pedal shelving groove. The escalator is characterized in that plug pin tubes are fixed on the downward surfaces at the left end and the right end of the front side of the front-edge pedal ; a front-edge pedal rollover prevention mechanism is arranged on each plug pin tube; the front-edge pedal rollover prevention mechanisms on the plug pin tubes at the left end and the right end of the front-edge pedal are also matched with the left shelf bar and the right shelf bar. Through the escalator, the safety is ensured; the view is not influenced; the operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of escalators, and in particular relates to an escalator with an anti-turnover function on the front pedals. Background technique [0002] The position of the aforementioned front pedal is located in front of the comb plate of the escalator. Since the front pedal (take the direction of passengers getting off the ladder as an example) is usually equipped with a rear pedal, the front pedal is located between the comb plate and the rear edge. Between the pedals, and the comb plate, front and rear pedals are all arranged on a pair of truss longitudinal beams on the upper part of the truss of the escalator. The space below the front and rear pedals is the machine room of the escalator. When the power facilities in the machine room are to be inspected, the front pedals are removed and the escalator is lifted from the escalator when the escalator stops running. Except for the space behind the front pedals, enter t...
