[0002] In high-altitude operations such as building exterior wall maintenance, high-altitude equipment repair, and power line inspection, high-altitude operation robots need to rely on adsorption devices to stably attach to the work surface in order to complete various precise operations. As the core adsorption component, the performance of the adsorption suction cup directly determines the safety and reliability of the robot's operation.

[0003] Currently, traditional high-altitude work robots use a single suction cup structure, which achieves adsorption by contacting the work surface with only a single suction cup. However, high-altitude work surfaces often have small bumps or uneven areas. Traditional suction cups cannot flexibly adjust the adsorption position, which can easily lead to local air leakage, resulting in a decrease in adsorption force or even adsorption failure, posing a safety hazard of robot falling. Utility Model Content

[0006] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following: In this invention, the mounting component and the adsorption component are securely installed through the four fixing holes and four first screw holes of the fixing plate. The mounting component enables flexible disassembly and fixation of the negative pressure generating component.

[0021] It should be noted that the present invention relates to an automatically adjustable suction cup for a high-altitude work robot. The main suction cup 65 of the suction component 6 works with the first silicone suction pad 66 to achieve main adsorption. The L-shaped support tube 67, spring 68, and movable rod 691 drive the auxiliary suction cup 69 to make fine adjustments to adapt to the small protrusions on the working surface.

[0022] In one possible implementation, four fixing holes 2 are provided, and the four fixing holes 2 are respectively opened at the four corners of the right end of the fixing plate 1.

The negative pressure generating component 4 is fixed by the mounting component 3. The overall structure is subjected to uniform force, which improves the stability of the device installation and prevents the components from loosening during high-altitude operations.

The first slot 34 is opened at the upper end of the mounting plate 31. There are two second slots 35, two second screw holes 36, a first bolt 33, a second locking plate 37, and a third screw hole 38.

The two third screw holes 38 are both opened at the right end of the first locking plate 32 and are located on both sides of the two second locking plates 37 respectively.

[0025] It should be noted that the two second slots 35 and the second screw holes 36 are correspondingly set with the two second plates 37 and the third screw holes 38. Together with the first slot 34 and the first plate 32, they provide multiple sets of positioning and fixing points for the connection between the mounting plate 31 and the first plate 32, thereby improving the connection accuracy of the mounting component 3 and avoiding component misalignment.

[0026] In one possible implementation, the first locking plate 32 is movably engaged in the first locking groove 34, the two second locking plates 37 are respectively movably engaged in the corresponding second locking grooves 35, and the outer surfaces of the two first bolts 33 are respectively threaded to the inner wall of the corresponding second screw hole 36 and respectively extend into the corresponding third screw hole 38.

[0027] It should be noted that the first card plate 32 and the second card plate 37 are movably engaged with the first card slot 34 and the second card slot 35 respectively, and are fixed by the first bolt 33 passing through the second screw hole 36 and the third screw hole 38. This facilitates the installation and disassembly of the component 3 and the micro vacuum pump 42 on it, while ensuring a firm connection and adapting to the needs of different robots.

[0028] In one possible implementation, the left end of the L-shaped plate 41 is fixedly connected to the right end of the two second clamping plates 37, the lower end of the micro vacuum pump 42 is fixedly installed on the lower inner wall of the L-shaped plate 41, the rear end of the gas pipe 43 is inserted and fixedly connected to the front end of the micro vacuum pump 42, and the switch valve 44 is inserted and movably installed on the outer surface of the gas pipe 43.

[0029] It should be noted that the L-shaped plate 41 is fixed by two second clamping plates 37, providing a stable installation base for the micro vacuum pump 42. The air pipe 43 is tightly connected to the micro vacuum pump 42, and the switching valve 44 flexibly adjusts the air path to ensure stable and controllable negative pressure transmission, adapting to the adsorption force requirements of different working surfaces.

[0030] In one possible implementation, four second bolts 62 and four fourth screw holes 63 are provided. The left end of the support tube 64 is fixedly connected to the center of the right end of the mounting plate 61. The left end of the main suction cup 65 is fixedly connected to the right end of the support tube 64.

The right ends of several movable rods 691 are fixedly connected to the left ends of the corresponding auxiliary suction cups 69. The left ends of several second silicone suction pads 692 are fixedly connected to the right ends of the corresponding auxiliary suction cups 69.

[0031] It should be noted that the four second bolts 62 and the fourth screw hole 63 ensure a stable connection between the mounting plate 61 and the main suction cup 65. The support tube 64 connects the mounting plate 61 and the main suction cup 65 in the center. The first silicone adsorption pad 66 enhances the sealing of the main adsorption. Several L-shaped support tubes 67, springs 68, and auxiliary suction cups 69 work together to adapt to the small protrusions on the working surface. Combined with the second silicone adsorption pad 692 and the movable rod 691, a "main + auxiliary" adsorption structure is formed to improve the adsorption stability.

[0032] In one possible implementation, the outer surfaces of the four second bolts 62 are threaded to the inner wall of the corresponding fourth screw hole 63 and extend into the corresponding first screw hole 5.

[0033] Several L-shaped support tubes 67 are arranged in a ring array around the center of the main suction cup 65.

The left ends of the several movable rods 691 are interlocked and movably connected to the right ends of the corresponding L-shaped support tubes 67.

[0035] It should be noted that the L-shaped support tubes 67 are arranged in a ring array to ensure uniform auxiliary adsorption force. The movable rod 691 moves flexibly within the spring 68, guiding the auxiliary suction cup 69 to make fine adjustments, preventing the spring 68 from shifting, and improving the reliability of auxiliary adsorption.

[0036] In one possible implementation, the end of the gas pipe 43 away from the micro vacuum pump 42 passes through the lower inner wall of the L-shaped plate 41 and extends to the outer surface of the support pipe 64, where it is inserted and fixedly connected to the outer surface of the support pipe 64.

[0037] It should be noted that the air pipe 43 passes through the L-shaped plate 41 and is tightly connected to the support pipe 64, ensuring that the negative pressure generated by the micro vacuum pump 42 can be efficiently transmitted to the main suction cup 65, reducing air leakage, ensuring stable main suction force, and meeting the suction needs of high-altitude operations.

[0038] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following: In this utility model, the mounting component 3 and the adsorption component 6 are securely installed through the four fixing holes 2 and the four first screw holes 5 of the fixing plate 1.

The micro vacuum pump 42 of the negative pressure generating component 4 is started, and the negative pressure is transmitted to the support tube 64 of the adsorption component 6 through the air passage 43. The main suction cup 65 works with the first silicone adsorption pad 66 to achieve main adsorption. Several L-shaped support tubes 67, springs 68, and movable rods 691 drive the auxiliary suction cup 69 to finely adjust and adapt to the protrusion of the working surface.
