Description

Guide rail frame for mounting escalator

Technical Field

The invention relates to the technical field of elevators, in particular to a guide rail frame for mounting an escalator.

Background

Escalators, or escalators for pedestrians, escalator handrails, escalators, are a class of escalators with circulating moving steps, which are stationary electrically driven devices for transporting passengers in an upward or downward inclination. The escalator is generally inclined, a pedestrian can automatically take the steps to the other end of the escalator when walking on one end station of the escalator, the steps can be kept horizontal all the way, handrails which synchronously move with the steps are arranged on two sides of the escalator and are held by a user, the escalator can always walk in one direction, but most of the steps can be controlled by managers according to the needs of time, people flow and the like, the other type of pedestrian transportation tool which is very similar to the escalator is an automatic sidewalk, the two types of transportation tools are mainly automatic sidewalks without steps, and most of the transportation tools can only walk on the flat ground or slightly incline.

The ladder way guide rail of the escalator comprises all guide rails, return rails and corresponding supports of main and auxiliary wheels. The ladder way is a closed circulating system, and comprises an upper ladder way system, a lower ladder way system, a traction chain and a rotary wall part. The escalator guide rail system is used for ensuring that steps follow a preset track. When the step chain is installed, the step chain idler wheel needs to be clamped in the guide rail, the step chain idler wheel is positioned through the guide rail, the positioning of the step chain is realized, when the roller of the step chain runs, the rollers at two ends of the step chain are absolutely parallel, but the roller of the common step chain at present is usually directly clamped in the guide rail, a gap is formed between the inner wall of the guide rail and the roller, the fit gap between the roller and the inner wall of the guide rail is increased along with the increase of the service time, so that the step chain is easy to shake during running, in addition, when the escalator runs, the maximum pulling force borne by the step chain is generally positioned at the upper corner and the lower corner of the escalator, namely the R section which is generally called in the industry, when in operation, the R section needs to bear the impact of the step chain during operation and the load of passengers, after long-time use, easily causes the R-section to be deformed by force, and for this reason we propose a guide rail frame for installing an escalator to solve the above-mentioned problems.
