Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude cleaning robots, in particular to a high-altitude glass cleaning robot. Background Art

[0002] At present, there are more and more high-rise buildings, and various skyscrapers have become a beautiful landscape in modern cities. Because glass curtain walls have good lighting, heat preservation and moisture resistance, and are practical and beautiful, many high-rise buildings are equipped with glass curtain walls on the outside. However, in order to ensure the neatness and beauty of the building's appearance, it is necessary to clean the glass wall regularly to beautify the city's appearance. At present, the cleaning methods used are hanging basket cleaning and lifting table cleaning, both of which are labor-intensive, costly, and dangerous.

[0003] Existing high-altitude glass cleaning robots are usually suspended on the outside of the glass using steel cables. The steel cables are limited and pulled so that the cleaning machine approaches the glass and performs cleaning. When such suspended robots are cleaning the glass, the scrubbing rollers of the robots have little squeezing force on the glass during operation, and their ability to scrub dust and stains on the glass is weak. The cleaning effect is not good, the wind resistance is poor, and the robots will swing when encountering strong winds. In addition, the construction of the steel cables is time-consuming and labor-intensive. The cleaning robot can only move along the direction of the steel cables and cannot automatically adjust the cleaning direction, thereby reducing the efficiency of glass cleaning.

Then the electric suction cup on the mounting plate releases the adsorption and fixation of the glass, adjusts the angle of the mounting plate and moves it back into the receiving groove, so that the travel route can be automatically adjusted as needed without manual adjustment.

[0031] Example: Reference Figure 1-6 A high-altitude glass cleaning robot shown in the figure comprises a top plate 1 and a bottom plate 2, two vertical plates 8 are fixed on the upper surface of the bottom plate 2, a back plate 7 is fixed on the lower surface of the top plate 1, the back plate 7 and the vertical plates 8 are slidably matched, a group of second electric push rods 16 are embedded and fixed at the bottom of the back plate 7, the output end of the second electric push rod 16 is fixedly connected to the bottom plate 2, the top plate 1 and the bottom plate 2 are symmetrically arranged, and an adsorption component 3 for adsorbing glass is provided on one side of the top plate 1 and the bottom plate 2;

[0032] A first driving box 15 is fixed to one side of the back plate 7, and a freely liftable water tank 4 is transmission-connected between the top plate 1 and the first driving box 15. A scrubbing roller 5 is fixedly installed on the top and bottom of the water tank 4. A receiving groove 22 is provided in the middle of the upper surface of the water tank 4, and a second driving box 18 is slidably fitted in the receiving groove 22. A driving shaft is rotationally connected to one side of the second driving box 18, and the driving shaft is fixedly connected to the rotating shaft 20. A mounting plate 6 is fixed to one end of the rotating shaft 20, and two electric suction cups 37 are fixed to one side of the mounting plate 6. A third electric push rod 19 is fixedly installed in the receiving groove 22, and an output end of the third electric push rod 19 is fixedly connected to the second driving box 18.

[0033] In the actual glass cleaning process, the robot needs to be manually placed against the glass so that the adsorption components 3 on the top plate 1 and the bottom plate 2 are pre-adsorbed on the outside of the glass, and the entire robot is fixed on the outside of the glass. The water tank 4 sprays clean water on the glass, and the water tank 4 reciprocates up and down, and the scrubbing roller 5 cleans the high-altitude glass. When it is necessary to move downward, the adsorption component 3 on the bottom plate 2 releases the adsorption and fixation of the glass and moves away from the glass. After the second electric push rod 16 pushes the bottom plate 2 down to the maximum range, the adsorption component 3 on the bottom plate 2 approaches the glass again and adsorbs and fixes it. Subsequently, the adsorption component 3 on the top plate 1 removes the adsorption of the glass and moves downward under the drive of the second electric push rod 16, and is adsorbed and fixed to the glass again. Such reciprocating operation can realize the automatic vertical movement of the robot during the cleaning operation; when it is necessary to adjust the moving route, the third electric push rod 19 pushes the second drive box 18 to move outward and is located on the mounting plate 6 The electric suction cup 37 on the top plate 1 and the bottom plate 2 contacts with the glass surface and is adsorbed on the glass surface. At this time, the adsorption components 3 on the top plate 1 and the bottom plate 2 simultaneously release the adsorption and fixation of the glass and move away from the glass. The driving shaft in the second driving box 18 rotates a certain angle. Since the rotating shaft 20 is fixed to the mounting plate 6, the second driving box 18 will rotate the same angle with the rotating shaft 20 as the axis, thereby causing the entire robot to rotate synchronously by a certain angle. After the angle adjustment is completed, the adsorption components 3 on the top plate 1 and the bottom plate 2 simultaneously approach the glass and are adsorbed and fixed on the glass. Then the electric suction cup 37 on the mounting plate 6 releases the adsorption and fixation of the glass. The driving shaft on the second driving box 18 drives the mounting plate 6 to rotate in the opposite direction back to the initial position again. Then the third electric push rod 19 drives the second driving box 18 to move into the storage slot 22, so that the mounting plate 6 and the electric suction cup 37 are moved back into the storage slot, thereby completing the automatic adjustment of the robot's movement route.

[0034] In this embodiment, in order to ensure that the adsorption component 3 is stably adsorbed and fixed on the glass surface, the adsorption component 3 includes a horizontal plate 31 fixedly installed on the surface of the top plate 1, and a group of first electric push rods 33 are fixed on the horizontal plate 31. The output end of the first electric push rod 33 is fixed with a connecting plate 32, and one side of the connecting plate 32 is fixed with a plurality of horizontal bars 34 slidably connected to the upper surface of the top plate 1, and one end of the horizontal bar 34 is fixed with the same electric suction cup 37, and a T-block 36 is fixed to the lower surface of the horizontal bar 34. T-slots 12 are opened at the positions of the upper surface of the top plate 1 corresponding to the horizontal bars 34, and the T-blocks 36 are slidably fitted in the T-slots 12. A support rod 35 inclined upward is fixed to the upper surface of the horizontal bar 34, and a same electric suction cup 37 is fixed to one end of the support rod 35.

[0035] By driving the connecting plate 32 to move left and right through the first electric push rod 33 on the cross plate 31, the electric suction cup 37 on the cross bar 34 and the support rod 35 can be moved closer to or away from the glass. After the electric suction cup 37 approaches the glass surface, it will automatically adsorb on the glass after power is turned on. The arrangement of multiple cross bars 34, support rods 35 and the electric suction cups 37 thereon can enable the adsorption assembly 3 to be stably adsorbed and fixed on the glass surface. The sliding cooperation between the T-block 36 and the T-slot 12 allows the cross bar 34 to always slide stably and linearly on the surface of the top plate 1.

[0036] In this embodiment, in order to make the lifting plate 14 slide stably vertically between the top plate 1 and the first driving box 15, the driving shaft in the second driving box 18 drives the rotating shaft 20 to rotate, and a transmission component for driving the two threaded screws 13 to rotate synchronously is provided in the first driving box 15. A lifting plate 14 is fixed to one side of the water tank 4. The lifting plate 14 is sleeved on the threaded screw 13 and is threadedly connected to the threaded screw 13. A plurality of spray heads 21 are fixedly installed on one side of the water tank 4. A servo motor is fixedly installed in the second driving box 18, and the rotating shaft of the servo motor is transmission-connected to the driving shaft through a gear set.

[0037] The transmission assembly in the first drive box 15 drives the two threaded screws 13 to rotate synchronously, so that the threaded screws 13 drive the lifting plate 14 to move vertically up and down, driving the water tank 4 to reciprocate up and down, so that the washing roller 5 cleans the high-altitude glass. The rotating shaft of the servo motor in the second drive box 18 drives the driving shaft to rotate through the gear set, and the clean water in the water tank 4 is sprayed onto the glass through the spray head 21.

[0038] In this embodiment, in order to improve the stability of the top plate 1 and the bottom plate 2 during relative sliding, a group of limit columns 9 are fixed between the top plate 1 and the bottom plate 2, the back plate 7 and the vertical plate 8 are both slidably sleeved on the limit columns 9, the two vertical plates 8 are symmetrically arranged relative to the axis of the bottom plate 2, an end block 10 is fixed to the top of the vertical plate 8, and a sliding groove 11 is provided on both end surfaces of the back plate 7. The end block 10 slides in the sliding groove 11, and a spring 17 is fixed between the end block 10 and the bottom of the sliding groove 11. The spring 17 can make the connection between the back plate 7 and the vertical plate 8 more stable, thereby improving the structural strength.
