Description

Subway shield door wall climbing cleaning robot with crossing function Technical Field The utility model relates to the technical field of wall climbing cleaning robots, in particular to a subway shielding door wall climbing cleaning robot with a crossing function. Background The subway shielding door is used as an important facility of a subway station, and the cleaning condition of the subway shielding door not only affects the attractiveness of the station, but also relates to the visual experience of passengers and the overall image of subway operation. At present, the traditional cleaning mode mainly depends on manual work, the area of a subway shielding door is large, manual cleaning consumes a great deal of manpower and time cost, cleaning work is difficult to comprehensively and timely develop in the subway operation period, the cleaning frequency is limited, and dirt is easily accumulated in the shielding door. Furthermore, manual cleaning requires personnel to work near the track, and the subway running environment is complex, which exposes the cleaning personnel to a great safety risk. The existing cleaning equipment has obvious defects when dealing with the special structure of the subway shielding door. The step distance exists between the fixed door and the sliding door on the shielding door, and the structural difference makes the common cleaning equipment difficult to cross over the obstacle, so that the whole shielding door cannot be continuously and seamlessly cleaned, dead angles exist in cleaning work, and the cleaning effect is affected. Although automated cleaning devices are increasingly used in various fields, wall climbing cleaning robots with special structures and cleaning requirements, which are specific to subway shield doors, are lacking. Disclosure of utility model The utility model aims to provide a subway shielding door wall-climbing cleaning robot with a crossing function, which realizes the step distance crossing between a fixed door and a sliding door on a subway shielding door, can continuously and seamlessly clean the whole shielding door, and effectively improves the cleaning efficiency and the flexibility. In order to achieve the above purpose, the utility model provides a subway shielding door wall climbing cleaning robot with a crossing function, which comprises a base, wherein an adsorption unit is arranged in the center position above the base, a driving unit, a cleaning unit and a crossing unit are respectively arranged around the adsorption unit, the driving unit, the cleaning unit and the crossing unit are connected with the base, the driving units are symmetrically distributed on two sides of the base, a lifting structure and a rotating structure are arranged on the crossing unit, a sliding block is arranged on the rotating structure, a guide rail is arranged on the lifting structure, and the lifting structure and the guide rail are connected through the sliding block and the guide rail. Preferably, the adsorption unit comprises a direct current motor, a motor fixing seat, a centrifugal fan and a main sucker are sequentially arranged at the bottom of the direct current motor, and a sealing ring is arranged on the round edge of the main sucker. Preferably, the driving unit comprises a first pulse motor, a first coupling is arranged at the output end of the first pulse motor, the first coupling is connected with a driving wheel through a bearing seat arranged at the output end of the first coupling, the driving wheel is connected with a first belt pulley through the bearing seat, a synchronous belt is arranged on the first belt pulley, the driving wheel is connected with a second belt pulley through the first belt pulley and the synchronous belt, and the second belt pulley is connected with a driven wheel through the bearing seat.
