Description

Technical Field

[0001] This utility model relates to a rectangular vacuum suction cup suitable for inclined hoisting, belonging to the technical field of industrial manufacturing. Background Technology

[0002] In industrial manufacturing, vacuum suction cups are frequently used for lifting operations. Rectangular vacuum suction cups are typically used when lifting heavy loads.

[0003] Compared to ordinary circular vacuum suction cups, rectangular vacuum suction cups have a larger contact area, and a single suction cup can achieve a load capacity of more than 1 ton. Several are often used simultaneously for lifting operations with heavy loads. However, because a rectangular vacuum suction cup is a large rectangle, traditional rectangular vacuum suction cups can only be used on relatively flat workpiece surfaces and are not suitable for workpieces with uneven surfaces and large undulations.

[0004] To address this, a rectangular vacuum suction cup suitable for inclined hoisting is proposed. Utility Model Content

[0005] In view of this, the present invention provides a rectangular vacuum suction cup suitable for inclined hoisting, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

A chain body is movably connected to the surface of each of the two first chain pins, and a second chain pin is movably connected to the other end of each of the two chain bodies. A lower lifting plate is provided on the outer side of each of the two second chain pins, and a suction cup base plate is fixedly installed at the bottom of the lower lifting plate. A vacuum rectangular suction cup is provided at the bottom of the suction cup base plate.

[0007] More preferably, a manual slide valve is fixedly installed on the right side of the top of the suction cup base plate, and the output end of the manual slide valve is connected to the inner cavity of the vacuum rectangular suction cup.

[0011] More preferably, the top of the suction cup base plate is threaded with fixing bolts, and the bottom of the fixing bolts is threaded to the inner surface of the vacuum rectangular suction cup.

[0012] The present invention has the following advantages due to the adoption of the above technical solution:

[0013] I. This utility model, by setting up a balance link, chain body, lower hanging plate, suction cup base plate and vacuum rectangular suction cup, when encountering a workpiece with an uneven surface and large undulations, several sets of vacuum rectangular suction cups installed on the lifting equipment are simultaneously placed on the workpiece surface.

[0023] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] Example 1

[0026] like Figure 1-5 As shown, this utility model embodiment provides a rectangular vacuum suction cup suitable for inclined hoisting, including a balance link 1, a lifting shaft 2 is provided at the middle end of the balance link 1, and first chain pins 3 are provided on both the left and right sides of the balance link 1. Chain bodies 4 are movably connected to the surfaces of the two first chain pins 3, and second chain pins 5 are movably connected to the other ends of the two chain bodies 4. A lower lifting plate 6 is provided on the outer side of the two second chain pins 5, and a suction cup base plate 7 is fixedly installed at the bottom of the lower lifting plate 6. A vacuum rectangular suction cup 9 is provided at the bottom of the suction cup base plate 7.

[0027] By setting up a balance link 1, chain body 4, lower lifting plate 6, suction cup base plate 7, and vacuum rectangular suction cups 9, when encountering workpieces with uneven surfaces and large undulations, several sets of vacuum rectangular suction cups 9 installed on the lifting equipment are simultaneously placed on the workpiece surface. As the workpiece surface undulates, some vacuum rectangular suction cups 9 are tilted, while others are horizontal, thereby improving the stability of workpiece lifting and making it easier for operators to use.

[0028] Example 2

[0029] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, a manual slide valve 10 is fixedly installed on the right side of the top of the suction cup base plate 7. The output end of the manual slide valve 10 is connected to the inner cavity of the vacuum rectangular suction cup 9. A shaft hole 11 is opened on the surface of the balance link 1. The lifting shaft 2 is inserted into the inner cavity of the shaft hole 11 and is connected to the external lifting equipment. A first insertion hole 12 is opened on both the left and right sides of the balance link 1. Two first chain pins 3 are inserted into the inner cavities of the two first insertion holes 12. A second insertion hole 13 is opened on both the left and right sides of the top of the lower lifting plate 6. Two second chain pins 5 are inserted into the inner cavities of the two second insertion holes 13. A fixing bolt 8 is threadedly connected to the top of the suction cup base plate 7. The bottom of the fixing bolt 8 is threadedly connected to the inner surface of the vacuum rectangular suction cup 9.

[0030] By setting a manual slide valve 10, the air in the inner cavity of the vacuum rectangular suction cup 9 can be extracted, so that the vacuum rectangular suction cup 9 is in a vacuum state, ensuring the stability of workpiece hoisting. By setting a shaft hole 11, the lifting shaft 2 and the balance rod 1 can be connected to each other, thereby facilitating the disassembly and assembly of the balance rod 1 and the external hoisting equipment. By setting a first insertion hole 12, the first chain pin 3 can be connected to the balance rod 1, thereby facilitating the disassembly and assembly of the chain body 4 and the balance rod 1. By setting a second insertion hole 13, the second chain pin 5 and the lower lifting plate 6 can be connected to each other, thereby facilitating the disassembly and assembly of the chain body 4 and the lower lifting plate 6. By setting a fixing bolt 8, the vacuum rectangular suction cup 9 can be installed, improving the convenience of connecting the vacuum rectangular suction cup 9 and the suction cup base plate 7.

[0031] In operation, a conventional vacuum rectangular suction cup 9 is directly connected to two lifting points of the lifting equipment via two chain bodies 4. Because the chain length is fixed, the vacuum rectangular suction cup 9 cannot be tilted for lifting. Our designed vacuum rectangular suction cup 9, suitable for tilting, uses a balance rod 1 to suspend two chain bodies 4. Furthermore, the balance rod 1 is not directly connected to the lifting equipment; instead, it is connected via a lifting shaft 2 mounted on the balance rod 1. This results in only one connection point with the lifting equipment.

[0032] When encountering workpieces with uneven surfaces and large undulations, several sets of vacuum rectangular suction cups 9 installed on the lifting equipment are placed on the workpiece surface simultaneously. As the workpiece surface undulates, some vacuum rectangular suction cups 9 are tilted, while others are horizontal. At this time, the vacuum generator uses the manual slide valve 10 of each vacuum rectangular suction cup 9 to evacuate the inside of each vacuum rectangular suction cup 9, so that each vacuum rectangular suction cup 9 generates vacuum suction force. After vacuum suction is completed, the lifting equipment is raised. At this time, the tilted vacuum rectangular suction cups 9 have a fixed chain body 4, and the lifting shaft 2 is connected to the lifting equipment. Therefore, the balance link 1 will also tilt with the tilt of the vacuum rectangular suction cup 9, thereby achieving tilted suction of the workpiece.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
