Problems solved by technology

[0004] However, in the above-mentioned invention patent application, the safety circuit is used to realize non-manipulation reversal, overspeed and stall protection. The system responds quickly and has high sensitivity. It has not been improved, especially when the elevator stops suddenly or breaks down suddenly, it will inevitably cause the passengers on the elevator to fall accidentally. For example, the escalator for the above-mentioned invention patent application is obviously not comprehensive for the protection of passengers, especially the elevator. Longer distances and steeper slopes are more likely to cause casualties

Embodiment Construction

[0027] A preferred embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0028] Such as figure 2 The illustrated embodiment of the stepped safety automatic escalator according to the present invention includes a step 1, a frame, a ladder guide rail 2, a guide wheel 3, and a step conveyor chain 4, and the frame is a stepped frame and is installed on a stepped ramp , the step 1 is installed on the ladder guide rail 2 and driven by the step conveyor chain 5 on the guide wheel 3 and guided by the guide wheel 3, the ladder guide rail 2 is a stepped ladder guide rail, The safety automatic escalator of the present invention adopts a step-by-step geometric structure design, which breaks the limitation of "one roll to the bottom" of the traditional structural escalator, and is especially suitable for occasions where the lifting distance is long and the slope is relatively steep. According to this structural design, even the esc...

Abstract

The invention discloses a step type safety automatic escalator which comprises steps (1), a framework, a step guiding track (2), a guiding wheel (3) and a step conveying chain (4). The framework is a step type framework and arranged on a step type slope, the steps (1) are arranged on the step guiding track (2), driven by the step conveying chain (4) on the guiding wheel (3) and guided by the guiding wheel (3). The step guiding track (2) is a step type step guiding track. The safety automatic escalator designed by means of the structure is reasonable in structure, high in safety and capable of reducing and avoiding passenger casualties.

Description

technical field [0001] The invention relates to a public facility automation control collar, in particular to a step-by-step safety automatic escalator. Background technique [0002] As a public facility, automatic escalators are used in many public places, such as large shopping malls, railway stations, subway stations, etc., but the current structural design of escalators still has a certain lack of safety, especially for some subway stations with long lifting distances. , In the case of steep slope, the safety design of the escalator is even more important. For example, at 9:36 a.m. on July 5, 2011, at the Zoo Station of Metro Line 4, there was an accident that caused casualties due to an escalator failure. [0003] The Chinese invention patent application with the application number 201010265233.6 discloses a reverse, overspeed and stall protection safety circuit for escalators and moving walks, including: an input control module for detecting the running status of esca...
