The working personnel stand in the hanging basket, the hanging basket can move up and down and left and right, and the telephone is arranged in the hanging basket, so that the hanging basket can be contacted with the outside at any time, and is safer; the window cleaning machine is the safest, practical and efficient special equipment for finishing high-altitude operation, and the structure of the window cleaning machine generally comprises a frame, a driving device, a guide rail system, a suspension device, a cleaning device, a control system and the like, and the internal structure is complex, and a plurality of parts are required to be combined and matched to ensure normal operation and efficient operation. The stable power output and reliable working efficiency of the window cleaning machine are realized by the driving device. The driving mode of the driving device comprises four modes of electric driving, pneumatic driving, hydraulic driving and manual driving; the different driving modes have respective advantages and adaptability, and the selection of the driving modes depends on the scale, the height and the working requirement of the window cleaning machine, and the driving modes are selected and configured according to specific situations.
Pneumatic drives are often used for high-rise buildings or large-scale installations. Pneumatic drive is to use compressed air to generate power to push the wiping device. The working principle of pneumatic transmission is that the mechanical energy output by an electric motor or other prime movers is converted into the pressure energy of air by an air compressor, and then the pressure energy of the air is converted into the mechanical energy by an executing element under the control of a control element and the cooperation of an auxiliary element, so that the linear or rotary motion is completed and work is done.
Pneumatic driving can enable the window cleaning machine to easily realize larger thrust and working range. The air is adopted as a transmission medium, so that the air is convenient to source and inexhaustible, is directly discharged into the atmosphere after being used, does not pollute the environment, and does not need an air return pipeline. The viscosity of the air is small, the pressure loss is small when the air flows in the pipeline, the pipeline is not easy to be blocked, and the air is not deteriorated, so that the energy is saved, the efficiency is high, and the cost is low. Compared with hydraulic and electric drive, the pneumatic drive has strong adaptability to the environment, and can be suitable for severe environments such as high temperature, inflammability, explosiveness, high dust, strong magnetic radiation, vibration and the like. Compared with hydraulic transmission, pneumatic transmission has fast reaction and quick action, and the required pressure and speed can be built up generally only by 0.02-0.03 s. In addition, the control is convenient, and the pneumatic control device not only can form a full pneumatic control loop, but also can realize rod combination control by combining with electricity and hydraulic pressure, so that pneumatic drive is widely applied to window cleaning machines.
