[0002] An escalator is an electric device, usually used to transport people between floors inside a building. It consists of a series of steps that run along a continuous looping chain or steel belt. The main function of an escalator is to facilitate passengers to move between floors, especially in high-rise buildings or busy commercial facilities, which can significantly reduce people's walking time. The escalator needs to use a fall prevention device during use.

[0003] The existing anti-fall device requires a large installation space and needs a large space for installation. The mounting bracket is connected by welding, and the base cannot be disassembled, which is inconvenient to use. In addition, the guardrail column is not hidden, which easily blocks the passenger's view. The load condition of the anti-fall device cannot be identified. When the anti-fall device exceeds the maximum load weight, it is easy to be damaged, thereby increasing safety hazards.

[0004] Therefore, we make improvements to this and propose a new escalator anti-fall device. Utility Model Content

[0042] Example 2

[0043] The guardrail monitoring assembly 9 includes a box body 901, which is arranged on one side of the bottom of the guardrail glass 5. A signal transmission cable 902 is arranged on one side of the box body 901, a telescopic rod 903 is arranged on the other side of the box body 901, and a special flat contact 904 is arranged on one side of the telescopic rod 903.

[0044] During the implementation process, the guardrail monitoring component 9 is composed of dual displacement sensors. The contacts of the displacement sensors are special flat contacts 904 with multiple contact positions. The side displacement sensors monitor the left and right movement of the guardrail glass 5, and the lower displacement sensors monitor the up and down movement of the guardrail glass 5.

Four through holes 11 are opened on both sides of the guardrail glass 5, and there are four fixing points for matching the guardrail columns 4. The guardrail columns 4 are completed by straight plate openings, and each column has an L-shaped glass claw 12, whose function is to fix and support the glass. The guardrail top edge seal 8 is formed by bending a stainless steel sheet. The entire top of the guardrail glass 5 has a guardrail top edge seal 8 to ensure the overall surface straightness of the guardrail glass 5. The guardrail monitoring component 9 is composed of dual displacement sensors. The contacts of the displacement sensors are special flat contacts 904 with multiple contact positions. The side displacement sensors monitor the left and right movement of the guardrail glass 5, and the lower displacement sensors monitor the up and down movement of the guardrail glass 5. When any of the displacement sensors detects that the guardrail glass 5 moves more than 4 mm, the guardrail monitoring component 9 receives a feedback signal, and an alarm will be issued at this time to stop the escalator.
