Plurality of pendulums masthead wheel mechanism for window cleaning equipment
Technical field
The utility model relates to a kind of window cleaning equipment assembly, particularly plurality of pendulums masthead wheel mechanism for a kind of window cleaning equipment.
Background technology
Existing window cleaning equipment is subject to force unbalance with each top wheel of top wheel mechanism, often can not be simultaneously stressed, and cause this top wheel mechanism balance poor, service life is short, and top wheel is fragile. And then affect job stability and the service time of window cleaning equipment.
Summary of the invention
The purpose of this utility model is a kind of window cleaning equipment of design plurality of pendulums masthead wheel mechanism.
To be solved in the utility model is that existing top wheel mechanism respectively pushes up wheel and is subject to force unbalance, can not be simultaneously stressed, and cause this top wheel mechanism balance poor, the problem of the fragile grade of top wheel.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
Plurality of pendulums masthead wheel mechanism for a kind of window cleaning equipment, comprises frame, is located at the wheel carrier in frame, and wheel carrier is installed in frame by major axis, and described wheel carrier is provided with the first wheels and the second wheels, and the first described wheels and the second wheels are located at respectively the both sides of major axis; The first described wheels comprise the first top wheel, the second top wheel, the first minor axis, the first transverse axis, clutch shaft bearing, the second bearing, described the first top wheel and the second top wheel are located at respectively on clutch shaft bearing and the second bearing, described clutch shaft bearing and the second bearing are located at respectively the two ends of the first transverse axis, the first described transverse axis is located on the first minor axis, and the first described minor axis is located on wheel carrier; The second described wheels comprise the 3rd top wheel, the 4th top wheel, the second minor axis, the second transverse axis, the 3rd bearing, the 4th bearing, described the 3rd top wheel and the 4th top wheel are located at respectively on the 3rd bearing and the 4th bearing, the 3rd described bearing and the 4th bearing are located at respectively the two ends of the second transverse axis, the second described transverse axis is located on the second minor axis, and the second described minor axis is located on wheel carrier.
The first described minor axis is provided with the first spacer, and the second described minor axis is provided with the second spacer. The outside of described clutch shaft bearing and the second bearing is respectively equipped with the first dust cap and the second dust cap, and the 3rd described bearing and the outside of the 4th bearing are respectively equipped with the 3rd dust cap and the 4th dust cap. Described major axis is provided with eccentric bushing.
The utility model has the advantages that: four top wheels of the present utility model can be simultaneously stressed, and stressed equalization; For the stressed deviation to top wheel that prevents that the structure of each joint telescopic column from causing, be provided with eccentric bushing outward at major axis, make top wheel have stressed by eccentric bushing adjustment.
