Description

Technical Field

[0001] The present application relates to the field of escalator safety, and in particular, to a safety system and an escalator. Background Art

[0002] Escalators are increasingly used and play an increasingly important role in people's daily activities, such as in shopping malls, hospitals, railway stations and other public places.

[0003] When using existing escalators, children may climb up and down while playing. When climbing, they may go over the handrails and fall, which poses a certain safety hazard. At the same time, the angle where the escalator contacts the upper floor is very likely to cause passengers' arms to be pinched, which poses a high safety risk. For example, the existing technology represented by the comparative document, an escalator safety monitoring system (publication number CN209815462U), which has a technical solution that can identify the passenger status of the escalator, reduce the probability of children riding the escalator alone, and provide safe escalator use, has this problem.

[0004] Therefore, we make improvements to this and propose a safety system and escalator. Summary of the Invention

[0005] The purpose of this application is to address the problem that during the use of existing escalators, children may climb up and down the escalator to play. When climbing, children may cross the handrail and fall, which poses certain safety hazards. At the same time, the angle where the escalator contacts the upper floor is very likely to cause the passengers' arms to be pinched, which poses a high safety risk.

An L-shaped platform is formed by the protective plate and the limit frames, which can prevent passengers from falling from the escalator body after climbing over the handrail body, thereby protecting passengers;

Then, the fixing frame is placed on the escalator body, and the compression spring rebounds, which can drive the suction cup to rest against the escalator body, thereby completing the fixation of the fixing frame;

[0012] The buffer mechanism includes two groups of connecting frames, and infrared sensors are embedded in the outer surfaces of the two connecting frames. An airbag is fixedly connected between the lower surfaces of the two connecting frames. The top of the airbag is connected to a gas generator. The controller controls the gas generator to inflate the airbag. The airbags at both ends expand to wrap and cushion the fallen passenger, which can reduce the damage to the passenger when falling accidentally.

[0013] As a preferred technical solution of the present application, one end of the compression spring is connected to the limiting sleeve, and the other end of the compression spring is connected to the limiting washer. The fixing component located on the left side of the inner wall of the fixing frame corresponds to the fixing component located on the right side of the inner wall of the fixing frame, and the two suction cups are abutted against each other.

When a passenger intends to climb over the handrail body, the infrared distance sensor located on the positioning frame can measure the distance between the passenger and the positioning frame. When the distance between the passenger and the positioning frame is at a dangerous distance, the controller controls the electric push rod to retract, and the electric push rod drives the limit frame to move through the adjustment frame, and the limit frame drives the pad to move, thereby increasing the height of protection, preventing the passenger's arm from being pinched at the angle where the escalator body contacts the upper floor, and at the same time increasing the protection area, further preventing passengers from falling from the escalator body.

[0018] As a preferred technical solution of the present application, the disinfectant tank is fixedly connected to the inside of the fixing frame, and the delivery pipe is fixedly passed through the outer surface of the fixing frame and extends to the outside of the fixing frame.

[0019] As the preferred technical solution of the present application, the two limiting shafts are respectively fixedly connected to the inside of the two movable grooves, one end of the limiting spring is connected to the inner wall of the movable groove, and the other end of the limiting spring is connected to the surface of the limiting ring. Under the action of the compression spring, the cleaning roller can fit tightly on the armrest body and can clean the surface of the armrest body.

[0020] A safety system comprises an escalator body. Handrail bodies are arranged on both sides of the upper surface of the escalator body.

[0023] In the scheme of this application:

[0024] 1. An L-shaped platform is formed by the protective plate and the limit frame, which can prevent passengers from falling from the escalator body after climbing over the handrail body, thereby protecting passengers. The infrared ranging sensor located on the positioning frame can measure the distance between the passenger and the positioning frame. When the distance between the passenger and the positioning frame is at a dangerous distance, the pad moves up, thereby increasing the height of the protection, preventing the passenger's arm from being pinched at the angle where the escalator body contacts the upper floor, and at the same time increasing the protection area, further preventing passengers from falling from the escalator body. This solves the problem in the prior art that children may climb up and down when riding escalators, and may climb over the handrail and fall when climbing, which poses certain safety hazards. At the same time, the angle where the escalator contacts the upper floor is very likely to cause the passenger's arm to be pinched, which poses a high safety risk.

[0025] 2. If a passenger falls while riding an escalator, the passenger will trigger more infrared sensors in a relatively short period of time. The controller controls the gas generator to inflate the airbags. The airbags at both ends expand to wrap and cushion the fallen passenger, which can reduce the damage suffered by the passenger in the event of an accidental fall. The cleaning nozzle sprays the handrail body to effectively disinfect and sterilize the surface of the handrail body. Under the action of the compression spring, the cleaning roller can fit tightly on the handrail body and clean the surface of the handrail body. BRIEF DESCRIPTION OF THE DRAWINGS

The limiting frame 25 movably passes through the protective plate 21 and the positioning frame 22, and the upper surface of the limiting frame 25 extends to the outside of the positioning frame 22. When passengers are riding the escalator, an L-shaped platform is formed by the set protective plate 21 and the limiting frame 25, which can prevent passengers from falling from the escalator body 1 after turning over the handrail body 11, thereby protecting the passengers.

The airbags 54 at both ends expand to wrap and cushion the fallen passenger, which can reduce the damage to the passenger when falling accidentally.

If a passenger falls while riding the escalator, the passenger will trigger more infrared sensors 52 in a relatively short time, and the controller controls the gas generator 53 to inflate the airbags 54. The airbags 54 at both ends expand to wrap and cushion the fallen passenger, which can reduce the damage to the passenger when falling accidentally. The escalator staff can inject disinfectant into the disinfectant tank 41, and the water pump in the disinfectant tank 41 can transport the disinfectant into the cleaning nozzle 43 through the delivery pipe 42, and then the cleaning nozzle 43 sprays the handrail body 11, effectively disinfecting and sterilizing the surface of the handrail body 11.
