The working process of the wall-climbing cleaning robot in the embodiment is as follows: (1) the moving mechanism of the wall-climbing cleaning robot adopts an X-direction slide block and a Y-direction slide block of an X-direction rodless cylinder 2 and a Y-direction rodless cylinder 4 to realize the movement in four directions, namely up, down, left and right. Specifically, taking fig. 4 as an example, taking the movement to the right side of the X-direction bracket 5 as an example, the Y-direction rod cylinder 3 contracts, the X-suction cup 600 is sucked to the wall surface and fixed, the Y-direction moving mechanism and the cleaning mechanism move to the right along the X-direction bracket 5 along with the X-direction slider, then, the Y-direction rod cylinder 3 extends, the Y-suction cup 700 is sucked to the wall surface and fixed, the X-direction rod cylinder 1 contracts, and the X-direction bracket 5 moves to the right.

The utility model discloses a wall climbing cleaning robot, including X to moving mechanism and Y to moving mechanism, carry in the course of the work and clean the mechanism, adsorb on the building wall, realize the abluent function of building wall. The main body part of the wall-climbing cleaning robot is composed of two cross-shaped frames which can translate mutually, wherein any one frame can translate relative to the other frame, precisely, two moving supports are connected with an X-direction sliding block on an X-direction rodless cylinder 2 and a Y-direction sliding block on a Y-direction rodless cylinder 4 to move, and each frame is provided with a 'leg and foot structure' which can be controlled independently in a group. The 'leg-foot structure' comprises an X-direction rod cylinder 1 and a Y-direction rod cylinder 3, and the extension and retraction of a Z-direction cylinder rod enable the robot body to be lifted up and down. Along with the alternate absorption of the legs and the relative motion of the frame body, the robot realizes the function of freely moving the wall surface. The frame structure mainly depends on the structures of the degrees of freedom of the X-direction support 5 and the Y-direction support 7 and the degrees of freedom of the X-direction rod cylinder 1 and the Y-direction rod cylinder 3, and each part has a simple structure and meets the requirements of flexibility and maneuverability. For example, if it is actually required that the wall-climbing washing robot can cross an obstacle of 50mm, the capability of raising by at least 50mm is required for the X-direction rod cylinder 1 and the Y-direction rod cylinder 3.
The utility model discloses a wall climbing cleaning robot can be applied to the multiple wall of waiting to wash, for example the hair wall, including cement, concrete wall etc. the brush hair material of round brush 12 that uses at this time is the metal preferred, and the wearability is good. For a relatively smooth glass or metal wall surface, the rolling brush 12 made of rubber, plastic or wood fiber can be used.
During operation, some walls can be cleaned only by rotating the rolling brush 12, construction requirements are met, cleanliness of some walls is high, and external water sources can be introduced. Specifically, a pipeline 13 is detachably connected to the motor fixing plate 9, a spray head 14 is fixed to the bottom of the pipeline 13, and the spray head 14 is inclined towards the rolling brush 12.

The material of the sucker (including the X sucker and the Y sucker) in the utility model can be made of nitrile rubber, and has larger breaking force. Compared to the magnetic attraction type, it is the cheapest method to attract an object to a wall surface by a suction cup. The sucking discs made of the rubber can be operated at high temperature, and the sucking discs made of the silicon rubber are very suitable for grabbing products with rough surfaces; suction cups made of polyurethane are very durable. In actual production, if oil resistance is required for the suction cup, it is conceivable to manufacture the suction cup using a material such as polyurethane, nitrile rubber, or a vinyl-containing polymer. In general, in order to prevent the surface of the glass wall from being scratched, it is preferable to select a suction cup with bellows made of nitrile rubber or silicone rubber.

Because the support structure used as the wall climbing cleaning robot is likely to be contacted with water frequently, even if the probability of oxidation is not very high for high-strength aluminum alloy, the support structure can be oxidized after a long time, and the support parts are not easy to replace. Therefore, after the cutting process, a rust inhibitive paint coating is required to be coated on the surface of the part to prevent the above situation.
As a specific implementation manner, assuming that the weight of the wall-climbing cleaning robot is 20kg and the load is 15kg, three X suction cups 600 are fixed on each X suction cup fixing plate 6, three Y suction cups 700 are fixed on each Y suction cup fixing plate 8, and the diameters of the X suction cups 600 and the Y suction cups 700 are greater than or equal to 50 mm. The specific theoretical verification calculation mode is as follows: sucker diameter formula:
in the formula: m-bearing mass;
s is the suction coefficient of the suction cup, and the vertical suction S is 8;
p-vacuum pressure (-KPa);
n is the number of the suckers.
TABLE 1 suction cup parameters
The data obtained in Table 1 were substituted for formula (1):
the suction area is smaller than the diameter of the suction cup because the vacuum pressure deforms the suction cup. The degree of deformation differs depending on the material and shape of the suction cup and the hardness of the rubber, and therefore, a margin is required for calculating the diameter of the suction cup. The safety factor includes a deformed portion.
Adsorption area:
A=3.14*D2/(4*100) (2)
in the formula: a-adsorption area (cm)2);
D-sucker diameter (mm).
Substituting the formula (2) to obtain:
Amin=3.14*40.22/(4*100)=12.69cm2
although the diameter of the suction cup indicates the outer diameter of the suction cup, when an object is sucked by vacuum pressure, the rubber is deformed by the vacuum pressure, and the suction area is reduced accordingly. The reduced area is called the effective suction area, and the diameter of the sucker at the moment is called the effective sucker diameter.
According to the difference of vacuum pressure, the thickness of the rubber of the sucker, the friction coefficient with an adsorbed object and the like, the effective diameter of the sucker also has difference, and the general situation can be estimated to be reduced by 10%.
Selecting a sucker with the diameter D equal to 50 mm:
Ais effective=3.14*502/(4*100)*90%=17.66cm2>Amin
So a 50mm chuck is feasible.
