More piece crank arm type window cleaning equipment
Technical field
The utility model relates to a kind of more piece crank arm type window cleaning equipment.
Background technology
Existing window cleaning equipment cannot in the less room general work of space, and the interior recess that its workbench enters building is comparatively difficult; When the cranking arm of window cleaning equipment is faced upward and bowed action, suspension arm headstock level regulates difficulty.
Utility model content
The purpose of this utility model designs a kind of more piece crank arm type window cleaning equipment.
To be solved in the utility model is that existing window cleaning equipment cannot in the less room general work of space, and its workbench is difficult to enter the problem that the interior recess of building and described suspension arm headstock level regulate difficulty etc.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is: a kind of more piece crank arm type window cleaning equipment, comprise underframe, be located at the slew gear on underframe, be located at the lifting mechanism on slew gear, described slew gear is provided with pillar of cranking arm, described crank arm pillar and the first rear end of cranking arm hinged, first front end of cranking arm is hinged with Change-over frame, the front end of Change-over frame is hinged with second and cranks arm, be provided with pull bar above cranking arm first, one end of pull bar and the upper articulation of pillar of cranking arm, the other end and the Change-over frame of pull bar are hinged; Be provided with strut in the second bottom of cranking arm, described strut one end and Change-over frame hinged, the other end and second lower front of cranking arm is hinged; Be provided with suspension arm headstock in the second front end of cranking arm, the upper articulation levelling gear of suspension arm headstock, the other end of levelling gear be located at second crank arm on; Suspension arm headstock bottom is provided with suspension arm tip slewing mechanism, hangs with platform under hanging arm tip slewing mechanism; Hang in arm tip slewing mechanism and be provided with horizontal trigger switch, described horizontal trigger switch is connected with levelling gear.
The utility model has the advantages that: the utility model applies to the less roofing of space, by lower door opening space, the moulding cleaning that there is the edge of a wing on roof can be met, platform can be made to enter interior recess; Of the present utility model cranking arm is faced upward when bowing action, is triggered, makes levelling gear work, the piston action of cylinder (oil cylinder), make suspension arm headstock remain level by transversal switch; To crank arm and the second combinative movement of cranking arm by first, platform can be made to arrive plan-position in arbitrary work range.
