An air compressor 6 is fixed to the top surface of the horizontal side of the first right-angle frame 7. The horizontal side of the first right-angle frame 7 extends into the interior of the frame 1, which can reduce the overall volume of the device; the electrical control cabinet 4 is located on the outside of the frame 1 for convenient operation by workers.

[0025] like Figure 2 As shown, a placement platform 8 is fixedly connected to the top surface of the base plate 9, and a vacuum pump 5 is fixedly connected to the placement platform 8. A second right-angle bracket 27 is fixedly connected to the top frame of the long side of the frame 1. A pneumatic valve 24 is fixedly connected to the bottom surface of the horizontal side of the second right-angle bracket 27. One side of the pneumatic valve 24 is connected to an air extraction port 26, and the other side is connected to a three-way valve 25. Three suction cup assemblies 16 are also provided on the base plate 9. Each suction cup assembly 16 has a through hole 10 at a corresponding position on the base plate 9. A sealing sleeve 29 is fixedly connected to the through hole 10 to increase the airtightness of the pipeline.

[0026] In use, the vacuum pump 5 is first connected to the suction port 26 through the main pipeline, and then connected to the three branch pipelines through the through hole 10 and the three-way valve 25, and then connected to the suction cup assembly 16; the piston of the pneumatic valve 24 is controlled to move by the air compressor 6, so that the pneumatic valve 24 is used as a suction switch of the vacuum pump 5.

[0027] The middle part of the top frame of the two long sides of the frame 1 is provided with a secondary lifting ring 28, which is arranged at the center position of the frame 1 together with the main lifting ring 2, which is beneficial to improve the balance of the device when the crane is lifted.

[0028] As shown in Figure 3 each suction cup assembly 16 includes four connecting assemblies and a suction cup 18, the connecting assembly includes a connecting rod 11, the connecting rod 11 is arranged through the bottom plate 9, the top end of the connecting rod 11 is provided with a limiting ring 12, and the bottom end is provided with a connecting seat 15. A bushing 13 is also provided on the connecting rod 11, and a spring 14 is arranged between the bushing 13 and the connecting seat 15, which can buffer through the extension of the connecting rod 11 when absorbing heavy objects, reduce the wear of the connecting assembly, and prolong the service life.

[0029] As shown in Figure 4 the bottom surface of the connecting seat 15 is fixedly connected with the suction cup 18, and the suction cup 18 is composed of four layers of structures fixedly connected together, which are the air chamber plate 19, the air guide plate 20, the suction plate 21 and the flexible plate 22 from top to bottom. The chamber is provided in the air chamber plate 19, which is used as a unified path for extracting air to form a vacuum environment. As shown in Figure 6 a plurality of first air guide holes 30 are formed in the air guide plate 20, and each row of first air guide holes 30 is in the form of a cylinder. The top of the first air guide hole 30 is provided with a blocking plate 33, and the inside is provided with a blocking piece 23 in the form of a sphere; the center of the blocking plate 33 is provided with a blocking hole 34 in the form of a circle, and the diameter of the blocking hole 34 is smaller than the diameter of the blocking piece 23. As shown in Figure 7 a plurality of second air guide holes 31 corresponding to the positions of the first air guide holes 30 are formed in the suction plate 21, and the second air guide holes 31 are in the form of a polygon, and the diameter of the sphere of the blocking piece 23 is greater than the diameter of the inscribed circle of the polygon. A plurality of third air guide holes 32 corresponding to the positions of the second air guide holes 31 are formed in the flexible plate 22; the material of the flexible plate 22 can be selected from sponge, which can form a buffer when the suction cup 18 contacts the heavy object, and make the suction plate 21 and the heavy object adhere more closely, and the suction effect is better.

[0030] As shown in Figure 5As shown, taking the hoisting interlocking block as an example, the hook of the crane is connected with the main lifting ring 2 and the auxiliary lifting ring 28 through a rope, the device is moved to above the interlocking block, then is moved downward to make the suction cup 18 adhere to the surface of the interlocking block, and then the pneumatic valve 24 is opened, and the vacuum pump 5 starts to operate. In the part where the adsorption plate 21 contacts the solid surface 35 of the interlocking block, the first air guide hole 30 does not cause air leakage, and the internal and external air pressures are balanced, and the blocking piece 23 is at the bottom of the first air guide hole 30 due to gravity; in the part where the adsorption plate 21 does not contact the solid surface of the interlocking block (for example, the notch 36), the first air guide hole 30 causes air leakage, and the blocking piece 23 is brought to the upper part through the airflow generated by the pressure difference, the blocking hole 34 is closed, the negative pressure value in the whole suction cup 18 is ensured not to decrease, and finally the adsorption force is generated, the interlocking block is lifted, and then the interlocking block is moved to the splicing position.

[0031] In addition, a generator can be arranged on the frame 1, which is used as an independent power supply, so that the device does not need to be externally connected to the power supply.

[0032] Embodiment 2

[0033] As Figures 8-10 shown, the difference from embodiment 1 is that the shape of the second air guide hole 31 is petal-shaped, and the diameter of the ball body of the blocking piece 23 is greater than the diameter of the circle surrounded by all tangent points of the plurality of mutually tangent circles. Compared with the polygon, the petal-shaped air guide hole has a larger air volume and can form a vacuum environment faster to adsorb the heavy object.

[0034] It should be noted that the shape of the second air guide hole 31 in embodiment 1 and embodiment 2 is a standard graph, which is for the convenience of describing the relationship between the size of the blocking piece 23 ball body and the second air guide hole 31. When the size of the blocking piece 23 reaches the minimum requirement, that is, the blocking piece 23 cannot pass through the second air guide hole 31 under the limiting structure 17 of the second air guide hole 31, the shape of the second air guide hole 31 except the limiting structure 17 can be arbitrary.

[0035] In the description of the present application, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inner", "outer", "back", "middle" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0036] The above is only a specific embodiment of the present application, and cannot limit the scope of the present application. The replacement of equivalent components or equivalent changes and modifications within the scope of the present application should still be within the scope of the present application.
