In general, an escalator is a staircase-shaped device made to automatically go up and down floors by driving a plurality of steps rotating in a caterpillar by power, and is also called an automatic staircase.

These escalators were registered trademarks of Otis Corporation until they were designated as public English meaning moving stairs by the US Patent and Trademark Office in 1950.

As shown in Figure 1, the escalator (1) as described above has a pair of left and right handrails 10 installed along the slope between the upper and lower platforms with height, and a plurality of steps ( 20) is provided with a driving unit 30 to rotate in an endless orbit. The driving unit 30 includes a main driving sprocket 32 that rotates by receiving rotational force from the driving motor 31, a driving chain 33 coupled to the main driving sprocket 32 to rotate in an endless track, and the driving chain 33 ) and a driven sprocket 34 coupled thereto. In general, the driving motor 31 of the driving unit 30 is built under the upper platform, and by changing the rotational direction of the driving motor 31, the conveying direction can be changed up and down.

At this time, each of the plurality of steps 20 is coupled to the drive chain 33 adjacent to each other and rotates in an endless orbit together with the drive chain 33 . Specifically, each of the steps 20 includes a step 21 that a passenger can step on and stand on, a riser 22 having a curved surface downwardly at the rear end of the step 21, and the step 21 A pair of brackets 23 coupled to the lower left and right sides, respectively.

In the bracket 23, a driving roller 23a is coupled to the upper portion of the bracket 23 so that the stepping plate 21 can be maintained horizontally when the step 20 is raised and lowered in consideration of the inclination angle of the driving chain 33, and a following roller ( 23b) is bound. The driving roller 23a and the following roller 23b roll and rotate along the inclined surface, and the driving roller 23a is fixed to the driving chain 33 via the driving roller shaft 23c and moves together.

The upper and lower platforms for passengers to get on and off are made of a fixed horizontal floor, and the upper and lower ends of the moving step 20 start at a horizontal angle under the fixed horizontal floor, and at the beginning of the inclined surface, the stepping plate 21 moves the inclined surface while maintaining the horizontal angle. It follows the movement, allowing passengers to stand upright and climb up and down the slope. The inclination angle of the inclined surface is usually 30 to 35 degrees with respect to the horizontal.

There is no restriction on the height of the escalator 1, and the moving speed of the step 20 is possible up to 0.5m per second, but up to a maximum of 0.75m. The handrail is installed on the handrail 10 so that the step 20 moves in the same direction and at the same speed as the moving speed, so that the passenger can stand and hold it and move. In addition, the driving unit 30 is equipped with an electromagnetic brake and a governor, and a safety device that stops the operation in preparation for an emergency situation such as when the driving chain 33 is cut or the speed of the escalator becomes faster than a prescribed value. , for example, reverse running prevention or emergency stop systems are installed.

Since the above-mentioned escalator 1 is usually installed in a place with a lot of floating population such as subway stations, department stores, shopping centers, airports, etc. ) was hung or installed on or around each component.
