It will not walk about with pedal for escalator, and the first cover body 2, the second cover body 3 and the 3rd cover body 4 can leave centainly between pedal
Spacing so covers in vivo brush member, sponge component exposes the first cover body 2, the second cover body 3 and the 3rd cover body 4 and pedal
It is in contact, so as to carry out dedusting.
In the present invention, the drying component 9 includes an air-heater 91（Air-heater can also use dryer in practical application
To substitute）With two winding pipes 92, the air-heater 91 is fixed on the side wall of escalator 1, described two winding pipes
92 are arranged side by side in 4 inner upper wall of the 3rd cover body, and one end of described two winding pipes 92 seals, two winding pipes 92
The other end be connected through the 3rd cover body 4 with an air inlet main pipe 93；The air inlet main pipe 93 is connected with the air-heater 91；
Described two winding pipes 92 are located at the top of two sponge components 8 respectively, and 92 bottom part down of winding pipe opens up all more
A exhaust vent 921.Air-heater is passed through hot wind into air inlet main pipe 93, then hot wind is passed through the exhaust vent of two winding pipes 92
921 carry out outlet air, so as to which pedal be dried.
First cover body 2, the second cover body 3, the length of the 3rd cover body 4 are less than the length of 1 pedal of escalator, institute
State the first cover body 2, the second cover body 3, the 3rd width of cover body 4 and being of same size for 1 pedal of escalator.
It refers to shown in Fig. 4, is the structure diagram that component is dried in second embodiment of the invention.The second of the present invention is real
Apply example and first embodiment difference lies in：The drying component includes an air-heater 91（Air-heater can also in practical application
It is substituted with dryer）With one the 4th cover body 94, the air-heater 91 is fixed on the side wall of escalator 1, the 4th cover
Body 94 is located in the 3rd cover body 4, and a hollow cavity 95 is formed between the 4th cover body 94 and the 3rd cover body 4, the 4th cover body
Multiple through holes 941 is offered on 94, an air admission hole is offered on the 4th cover body 94（It is not shown）, the air-heater 91 is logical
A hose 96 is crossed to connect with the hollow cavity 95 through the air admission hole.Due between the 4th cover body 94 and the 3rd cover body 4
A hollow cavity 95 is formed, such hot wind can be passed into from hollow cavity 95 in the 4th cover body 94, filled in such 4th cover body 94
Full hot gas, so as to be dried to pedal.
Wherein, the first cover body, the second cover body, the 3rd cover body can clear up the same pedal of escalator successively,
I.e. first pedal of elevator can pass through the progress dedusting of the first cover body, and first pedal is cleaned using the second cover body, the
One pedal is dried using the 3rd cover body, so as to form the cleaning and drying operation of a continuous-flow type.Due to helping automatically
In ladder at least there are four stair treads to be located at horizontal plane, so the first cover body 2 of the present invention, the second cover body 3 and the
Three cover bodies 4 can carry out first three stair tread of horizontal plane continuous-flow type cleaning, i.e. the first rank pedal can be successively by the first cover
Body 2, the second cover body 3 and the 3rd cover body 4 carry out clear dirt, cleaning, drying operation, and second-order pedal can pass through the first cover body successively
2nd, the second cover body 3 and the 3rd cover body 4 carry out clear dirt, cleaning, drying operation, the 3rd rank pedal can pass through successively the first cover body 2,
Second cover body 3 and the 3rd cover body 4 carry out clear dirt, cleaning, drying operation.
The device of the invention is removably disposed on escalator treadboards, and escalator is carried out when so needs
Clear dirt operation, is directly removed when unwanted, and use is very convenient, passes through the first in vivo two the first brush members pair of cover
Escalator treadboards are swiped, then are absorbed the dust cleared by exhaust fan, thorough so as to be carried out to pedal
Clear dirt, then cleaned by the second in vivo second brush member of cover and spray head to the pedal after clear dirt, preferably by the
The in vivo sponge component of three covers and drying component carry out drying operation to the pedal after cleaning, and the pedal of escalator can be carried out
Clear dirt, cleaning and the operation of drying, so as to keep the clean of escalator.
The foregoing is merely presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with
Modification should all belong to the covering scope of the present invention.
