[0027] The cleaning element 85 includes two second hollow support blocks 851 and two rag blocks 852, the second hollow support blocks 851 are fixed to the inner side wall of the arc-shaped limit cover 71, and the rag blocks 852 are arranged at On the second hollow support block 851, the surface of the second hollow support block 851 is provided with a plurality of water outlet holes; in this way, the water in the water tank 82 can flow from the water outlet holes on the surface of the second hollow support block 851 to On the rag 852, so that the wet rag can clean the handrails in the grooves on both sides of the escalator; the dust removal member 86 includes a plurality of brushes, the plurality of brushes are fixed on the arc limit The inner side wall of the bit cover 71; the brush can firstly remove dust from the handrails in the grooves on both sides of the escalator;
[0028] The air outlet of the hot air blower 81 is connected with a main air pipe 811, the main air pipe 811 is connected with a first four-way valve 812, and the upper two sides of the arc-shaped limit cover 71 are provided with two first air guides One end of the first air guide tube 813 passes through the arc-shaped limit cover 71 to connect to the drying element 84, and the other end of the first air guide tube 813 is connected to the first air guide tube through a water pipe quick connector (not shown). The four-way valve 812 is connected. The upper side plate of the arc-shaped limit cover 71 is provided with a second air duct 814, one end of the second air duct 814 extends through the arc-shaped limit cover 71 to the arc-shaped limit cover In the hollow cavity 71, the other end of the second air guide tube 814 is connected to the first four-way valve 812 through a water pipe quick connector (not shown), and the upper surface of the upper side plate 75 of the arc limiting cover 71 is opened There are multiple air outlets 815; in this way, hot air can also flow out from the air outlets 815 on the side panel 75, so as to dry the front of the handrail belt and also dry the moisture on the first roller; When it is necessary to use a hot air blower to enter the main air pipe 811, connect the first air guide pipe 813 and the second air guide pipe 814 to the first four-way valve through the water pipe quick connector. When it is not needed, The hot air blower and the main air duct can be separated from the first air guide tube and the second air guide tube;
[0029] The water tank 82 is provided with a water pump, the water pump is connected to a water inlet main pipe 821, the water inlet main pipe 821 is connected with a second four-way valve 822, the arc-shaped limit cover 71 is provided on both sides of the middle part Two first water inlet pipes 823. One end of the first water inlet pipe 823 passes through the arc-shaped limit cover 71 and is connected to the cleaning element 85, and the other end of the first water inlet pipe 823 is connected to the cleaning member 85 through a water pipe quick connector (not shown). The second four-way valve 822 is connected. A second water inlet pipe 824 is provided on the middle side plate of the arc-shaped limit cover 71. One end of the second water inlet pipe 824 passes through the arc-shaped limit cover 71 and is located on the second roller. Above 73, the water can flow to the second roller 73; the other end of the second water inlet pipe 824 is connected to the second four-way valve 822 through a water pipe quick connector; a valve is provided on the water inlet main pipe 821; The water diversion pipe 77 is connected to the water storage tank 83. In this way, when the water tank is needed to send water to the water inlet main pipe 821, the first water inlet pipe and the second water inlet pipe 824 are connected to the second four-way valve through the water pipe quick connector. When not in use, the water tank and the water inlet pipe The main water pipe can be stripped from the first water inlet pipe 823 and the second water inlet pipe 824;
[0030] Among them, the main air pipe 811, the water inlet pipe 821, and the water diversion pipe 131 are hoses and all have a certain length. The telescopic rod can drive the arc-shaped limit cover 71 to move forward and backward. The two air guide pipes, the two first water inlet pipes, and the second water inlet pipe 824 are hard pipes, so that the two first air guide pipes, the second air guide pipe, the two first water inlet pipes, and the second water inlet pipe 824 can be arranged On the arc-shaped limit cover 71; in addition, the water pump, hot air blower, and telescopic cylinder can be controlled to start or close through a control box. The control principle of the control box is the prior art and will not be described in detail here. The side wall of the base has an opening, and the air inlet of the hot air blower is located on the opening, so that wind will flow in from the hot air blower.
[0031] In the present invention, the first air duct 813 passes through the arc-shaped limit cover 71 and is connected to the first hollow support block 841 of the drying element 84, so that the hot air in the first air duct 813 can be guided to On sponge block 842. The first water inlet pipe 823 passes through the arc-shaped limit cover and is connected to the second hollow support block of the cleaning element 85, so that the water in the first water inlet pipe 823 can be drained to the rag block of the cleaning element.
[0032] In order to better control the airflow on the main air pipe 811, in the present invention, an air inlet valve is provided on the main air pipe 811. In this way, the airflow can be controlled through the intake valve. The second water inlet pipe 824 is provided with a valve, so that the size of the water flowing onto the second roller 73 can be controlled through the valve.
[0033] In the present invention, a drying element, a cleaning element, and a dust removing element are sequentially arranged in the arc-shaped limit cover from top to bottom, so that the handrail belt in the grooves on both sides of the automatic handrail ladder is first cleaned by the dust removing element, and then passed The cleaning part cleans the handrail belt, and finally the drying part is used for drying, so that the handrail belt in the grooves on both sides of the automatic handrail ladder is cleaned by running water. The surface of the handrail belt is cleaned by the second roller, and then passed The first roller and the hot air blower dry the moisture on the surface of the handrail, so that the surface of the handrail is also cleaned. This patent does not require a lot of manpower and material resources, and is cleaned by flowing water, which is relatively clean.
[0034] In short, when the present invention is in use, the cleaning module is rotated to the handrail of the escalator through the motor and the rotating shaft, and then the arc-shaped limit cover is buckled on the escalator handrail through the telescopic rod, and the first roller and the The second roller cleans the surface of the handrail belt. The first air guide tube and the second air guide tube are both connected to the first four-way valve through the quick connector, and the first water inlet pipe and the second water inlet pipe are both connected through the quick connector It is connected with the second four-way valve, so that the handrail belts in the grooves on both sides of the escalator are cleaned and dried first through the cleaning parts and drying parts; when the device is not in use, the first air duct and the second The second air duct is removed from the first four-way valve, and the first water inlet pipe and the second water inlet pipe are removed from the second four-way valve; the cleaning module is folded by the motor and the rotating shaft against the side of the handrail belt. Therefore, the hot air blower 81, the water tank 82, and the water storage tank 83 are removed so as not to hinder pedestrians from walking on the escalator; the present invention is convenient to use and can effectively clean the surface of the handrail.
