The utility model content
The utility model purpose provides a kind of efficient, safe high building glass curtain wall cleaning device.
Realize the utility model technical scheme that purpose is taked: a kind of high building glass curtain wall cleaning device, comprise wiper mechanism, pull rope, roof walking mechanism and be fixed in the guide rail on roof, it is characterized in that: wiper mechanism comprises that two pairs is the right glass curtain wall vacuum cup that alternately is adsorbed in diagonal, and the connecting rod of vacuum cup is slidingly connected by piston-cylinder and wiper mechanism; Rail level has certain intervals from deck under the guide rail, and rail level is provided with the anti-dumping gear wheel under guide rail, and this anti-dumping gear wheel and roof walking mechanism fuse;
Drive four driven sprockets by a drive sprocket by chain in the wiper mechanism, each driven sprocket respectively connects a secondary cleaning brush;
After the cleaning brush of wiper mechanism, be furnished with the scraping blade of band spring;
The power of cleaning brush rotation, wiper mechanism lifting, roof walking mechanism all adopts direct current generator to provide in the wiper mechanism.
The utility model good effect: owing to take the fourth officer cleaning brush to work simultaneously, cleaning efficiency significantly improves.Design the anti-gear wheel that topples, capsizing case can not take place, avoided personnel's property loss.Adopt vacuum cup to be adsorbed on the glass curtain wall, allow cleaning brush tightly be attached on the glass curtain wall and clean, clean thoroughly clean.

The specific embodiment
The lifting of the utility model wiper mechanism is born by the hoist engine that is arranged on the roof walking mechanism.
Whether vacuum cup work is controlled by vavuum pump in the utility model wiper mechanism, vacuum cup stretches out from wiper mechanism or the Compressed Gas that is provided by compressor of withdrawing realizes that by piston-cylinder vacuum cup can slide up and down along the straight line chute of wiper mechanism by connecting rod.
The walking of the utility model roof walking mechanism comprises along the horizontal of guide rail moves, and it is by the chain transmission; Another moves and is and the vertically moving of horizontal mobile vertical direction, it can make wiper mechanism near or leave glass curtain wall, it is realized by rack-and-pinion.
The utility model course of work: put the initial position (the curtain wall upper left corner) of wiper mechanism in cleaning.Power-on switch, contactor, gas source switch, then wiper mechanism begins from top to bottom, cleans automatically from left to right.Specifically:
1) vertically moving of control roof walking mechanism allows wiper mechanism press close to curtain wall, stops behind the travel switch in touching;
2) vavuum pump 1 begins to bleed, the magnetic valve energising, and control compressed air stream direction allows first pair of cylinder of wiper mechanism stretch out, and first pair of sucker is adsorbed on the curtain wall;
3) the elevator electric motor starting loosens pull rope, and wiper mechanism at the uniform velocity descends under the deadweight effect, starts simultaneously to clean motor, drives cleaning brush and rotates the scouring curtain wall at a high speed;
4) behind the wiper mechanism decline 2s, vavuum pump 2 begins to bleed, the energising of respective electrical magnet valve, and control compressed air stream direction allows second pair of cylinder stretch out, and makes second pair of sucker also be adsorbed on the curtain wall; 0.5s after, vavuum pump 1 stops to bleed, and preceding magnetic valve outage is unclamped first pair of sucker;
5) behind the wiper mechanism decline 2s, vavuum pump 1 begins to bleed, the energising of respective electrical magnet valve, and control compressed air stream direction allows first pair of cylinder stretch out, and first pair of sucker is adsorbed on the curtain wall; 0.5s after, vavuum pump 2 stops to bleed, and the outage of respective electrical magnet valve is unclamped second pair of sucker;
6) constantly repeat 4), 5) step, allow the 1st pair and the alternately absorption of the 2nd pair of sucker, realize the asynchronous continuous walking of diagonal (imitative lizard creeps), keep wiper mechanism to be close to curtain wall and to descend continuously and clean;
7) when the infrared sensor that is contained in wiper mechanism bottom detected the curtain wall bottom, vertically moving of roof walking mechanism made wiper mechanism leave curtain wall, stopped after touching the outer stroke switch, and all power sources of wiper mechanism quit work;
8) the elevator motor reverses fast, and the traction wiper mechanism at the uniform velocity rises, when the infrared sensor on wiper mechanism top detects the curtain wall top, and stop motion;
9) after the roof walking mechanism moves right the distance of setting along guide rail, repeat above action.
The deadweight meeting of the utility model wiper mechanism produces the pulling force that leans forward to the roof walking mechanism, if the roof walking mechanism of not taking measures just is easy to be drawn topple.The utility model rail level under guide rail is provided with the anti-dumping gear wheel, and anti-dumping gear wheel and roof walking mechanism fuse, and have solved the problem of toppling well.
The utility model has increased a scraping blade that has spring in order not stay mottling after cleaning glass.
Utilize single-chip microcomputer (C8051F310) to realize the accurate coordination of each action, desirable motor speed and whole system automated job.The control of whole system automation divides two major parts to realize, one is control roof walking mechanism, and it makees the lead that can reduce aerial connection like this two for the control wiper mechanism, and the be more convenient for debugging of system of control circuit modularization.Coordinate control between four cylinders, two vavuum pumps and two five-way electromagnetic valves in the wiper mechanism, be easy to control by single-chip microcomputer.
