Description

Cleaning device for open air article surface
Technical field
The present invention relates to a kind of burnisher, especially for the burnisher of scrubbing open air article surface.
Background technology
Present open air article as the building surface (plastic-aluminum, ceramic tile body of wall and glass etc.) or the cleaning of road curb mainly is: smear washing agent to the surface that quilt is scrubbed earlier, the nylon brush rider-type brush that the workman is hand-held common is moving then, water flushing again.Though it is simple manual labor, labour intensity is very big; Simultaneously modern building is all than higher, so the workman needs carry out work high above the ground on boatswain chair or hanging basket, and not only operating efficiency is very low, but also dangerous, and human casualty accident easily takes place.
Summary of the invention
The object of the present invention is to provide a kind of physical labor intensity, high efficiency that can not only alleviate the workman, and safe again cleaning device for open air article surface.The present invention can hand, and also can be airborne, no matter but which kind of, the cleaning brush dish all is essential assembly.Brush dish of the present invention mainly includes: chassis, grooming thing, coupling piece and brush dish motor (containing decelerator).Wherein the chassis is a circular slab, and the one side is provided with the grooming thing, and as bristle, nonwoven etc., they can use separately, but also both are used in combination.Coupling piece is established in center at chassis opposite side (being non-grooming thing one side of establishing), and it can link to each other the chassis with brush coil motor output shaft.Preferably the motor fixed head links to each other with the angle adjustment part, it is 90 ° fanning strip that this angle adjustment part has two drift angles, be provided with 2~3 cylindrical voids near the arc limit of one piece plate, be provided with row's circular hole near the arc limit of another piece plate, the right-angle side of two fanning strips is linked to be bucket shape by connecting plate, is positioned at above-mentioned motor fixing plate and a connecting plate parallel (or vertical with another connecting plate) wherein near the bucket point.Be provided with two corresponding through holes at above-mentioned angle adjustment part near fan-shaped drift angle place, be provided with bolt in the hole.Above-mentioned cleaning brush dish is located on the movable support member of being handled by the people.When cleaning apart from ground the open air article surface below 9 meters, this support member adopts hand-held control stick, its upper end directly links to each other with motor fixing plate, also can link to each other indirectly by the angle adjustment part, when cleaning brush dish when being single, two corresponding through holes of control stick upper end are inserted in the above-mentioned bolt, on this control stick position corresponding, be provided with through hole with fanning strip cylindrical void or circular hole, be provided with spring detent in the hole, promptly this bayonet lock has an arcuate bombing leaf that is located in the control stick, be fixed with an end of pin on it, the free end of pin is towards the through hole of control stick.When the pin of elasticity bayonet lock reaches in certain circular hole of angle adjustment part, just make control stick and motor output shaft be fixed on a certain angle; When the pin of elasticity bayonet lock reaches in certain cylindrical void of angle adjustment part, just control stick and motor output shaft are fixed in certain angular range, brush dish operation angle can be adjusted within the specific limits automatically, to finish the cleaning of different work face.When cleaning brush dish when being a plurality of, the control stick upper end then links to each other with the brush plate rail, this brush plate rail has a framework, and on this framework, be provided with perpendicular brush dish fixed leg and which is provided with the nearly hole that links to each other with brush dish angle adjustment part, and the elasticity bayonet lock corresponding with the angle adjustment part.Above-mentioned control stick can be one of regular length, but many of preferably can fit together, so that adjust length according to actual needs.
When cleaning apart from ground the building surface more than 9 meters, the support member of above-mentioned brush dish promptly adopts brush dish bearing support, and the brush dish then links to each other with the brush plate rail of this bearing support.It is the horizontal gird on plane that this brush dish bearing support has face upwards, and its cross section is Π word or square shape, and the two ends of this crossbeam are inserted in respectively in the nearly hole of above-mentioned two vertical rigid rod lower ends, and flexibly connect by securing member.Above-mentioned crossbeam can be single, but together three of superposition preferably can make crossbeam extend to both sides like this, is transferred to and is beneficial to its fixing position so that will be fixed on fixed mechanism on the rigid rod.The upper end of this rigid rod links to each other with the steel cable lower end, and the steel wire rope upper end then is fixed on the crane that places the building top, can realize brush dish bracing frame moving up and down in a big way by this crane.The top that is preferably in above-mentioned two rigid rods is provided with an end of the buffer spring that prevents brush dish bearing support damage building surface, and the other end of this spring is a free end, and the material that can not damage building surface is established on the end top.A detent mechanism is respectively established in the bottom of above-mentioned two rigid rods, it has a rigidity sucker, each sucker mouth is established the software body material that increases sealing effectiveness, and the sucker middle part links to each other with telescoping tube one end, and this telescoping tube other end links to each other with vavuum pump on being located at rigid rod by conduit.Above-mentioned telescoping tube passes the through hole on two relative walls of rigid rod bottom square tube, two ends are positioned at outside the square tube, be provided with
