Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, in particular to a suction cup hanger for transporting steel plates. Background Art

[0002] Steel plates are flat-plate steel materials. During the production or use of steel plates, they need to be transported in batches many times. Since batch steel plates are large in size and heavy in weight, they cannot be transported by ordinary transport tools. Therefore, special equipment such as lifting machinery or forklifts are usually used for transportation. During the production of steel plates, molten steel needs to be poured into a continuous casting machine for casting, and then it needs to go through multiple rolling processes to be made into steel plates. This involves smelting, casting, rolling and other links, which require a large number of mechanical equipment and workers to operate. In the use of steel plates, they are mainly used in the manufacture of automobiles, ships, building structures and other fields, so they also need to go through cutting, welding and other processing processes; in general, steel plates, as important structural materials, play an irreplaceable role in modern industrial production and construction.

[0003] Existing steel plate lifting devices generally use suction cups to absorb and fix steel plates, and then use a lifting mechanism to drive the suction cups and steel plates to move up, thereby realizing the lifting of the steel plates. For example, Chinese patent announcement No. CN217050639U discloses "a steel plate automatic suction, lifting, handling and placement device", which is adjusted according to the size of the steel plate, and the handle is turned to drive the screw rod to rotate, thereby driving the sleeve to make the slider and the mounting plate slide toward each other, so as to adjust the suction cup to an appropriate position to match the specifications of the steel plate, and then the adjusting bolt is turned to adjust the suction cup to an appropriate height to complete the adjustment of the suction cup, thereby solving the problem of not being able to match the specifications of the steel plate.

[0004] However, in actual use, when the suction cup of the lifting device moves down and contacts the steel plate, the suction cup and the adjusting bolt are directly subjected to force, which makes the adjusting bolt and the suction cup easily deformed after long-term use, causing the position of the suction cup to change and unable to accurately adsorb the steel plate. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art that when the suction cup moves down and contacts the steel plate, the suction cup and the adjusting bolt are directly subjected to force, which makes the adjusting bolt and the suction cup easily deformed after long-term use, and proposes a suction cup hanger for transporting steel plates.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A suction cup hanger for transporting steel plates is designed, comprising a bracket, a hoisting mechanism with a hook, and an adsorption component, wherein the hoisting mechanism is arranged on the bracket, the hook of the hoisting mechanism is connected to a lifting frame, and the adsorption component is arranged on the lifting frame;

[0008] The adsorption assembly includes a suction cup, each of which is connected to an external vacuum device, and a connecting assembly corresponding to the suction cup is provided on the lifting frame;

[0009] The connecting component comprises a horizontal plate, a protective plate is arranged at the lower end of the horizontal plate, a connecting column is arranged at the lower end of the protective plate, the lower end of the connecting column is movably connected with the suction cup, and a spring is arranged between the suction cup and the protective plate.

[0010] Furthermore, a sealing member is provided at the lower end of the connecting column, and the upper end of the sealing member abuts against the suction cup to form a sealing structure.

[0011] Furthermore, a connector matching with the protective plate is fixedly provided on the connecting column, a through hole is opened on the horizontal plate, a supporting column matching with the through hole is fixedly provided on the upper end of the connector, and a limiting piece matching with the through hole is provided on the support column.

[0012] Furthermore, the limiting member includes a rotating portion rotatably connected to the supporting column, and a limiting portion corresponding to the through hole is fixedly provided on an outer wall of the rotating portion.

[0013] Furthermore, a guide groove cooperating with the limiting portion is formed on the inner wall of the through hole, and the guide groove is a spiral structure.

[0014] Furthermore, a torsion spring is connected to the support column, and the other end of the torsion spring is connected to the limiting member.

[0015] The utility model provides a suction cup hanger for transporting steel plates, which has the following beneficial effects:

[0016] In the utility model, the connecting column is movably connected with the suction cup, and a spring is arranged between the suction cup and the protective plate. When the suction cup contacts the steel plate, the suction cup stops moving downward due to force, while the connecting column still moves downward under the action of inertia. The pressure generated by the downward movement of the connecting column and the impact force generated by the suction cup contacting the steel plate are absorbed by the deformation of the spring, thereby extending the service life of the connecting column and the suction cup.

[0017] Secondly, in the utility model, the support column and the connecting column are connected to the cross plate by setting a plug-in part, and the support column is fixed by setting a limiter to prevent the support column and the connecting column from separating and falling off from the cross plate. By rotating the limiter to make it correspond to the guide groove in the through hole, the support column can be taken out and the suction cup can be replaced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4 A suction cup hanger for transporting steel plates comprises a bracket 1, a hoisting mechanism 2 with a hook and an adsorption assembly 3, the hoisting mechanism 2 is arranged on the bracket 1, and the hoisting mechanism 2 can move along the bracket 1, the hook of the hoisting mechanism 2 is connected with a lifting frame 4, and the adsorption assembly 3 is arranged on the lifting frame 4;

[0025] The adsorption assembly 3 includes a suction cup 31, and the suction cup 31 is connected to an external vacuum device through a conduit. A connecting assembly 5 corresponding to the suction cup 31 is provided on the lifting frame 4;

[0026] The connecting component 5 includes a transverse plate 51 , a protective plate 52 is provided at the lower end of the transverse plate 51 , a connecting column 53 is provided at the lower end of the protective plate 52 , the lower end of the connecting column 53 is movably connected to the suction cup 31 , and a spring 54 is provided between the suction cup 31 and the protective plate 52 .

[0027] In the utility model, the connecting column 53 is movably connected with the suction cup 31, and a spring 54 is provided between the suction cup 31 and the protective plate 52. When the suction cup 31 contacts the steel plate, the suction cup 31 stops moving downward due to the force, while the connecting column 53 will still move downward under the action of inertia. The spring 54 deforms to absorb the pressure generated by the downward movement of the connecting column 53 and the impact force generated by the suction cup 31 contacting the steel plate, thereby extending the service life of the connecting column 53 and the suction cup 31.

[0028] Furthermore, in this embodiment, a sealing member 55 is provided at the lower end of the connecting column 53, and the upper end of the sealing member 55 abuts against the suction cup 31 to form a sealing structure. When the steel plate is adsorbed, the connecting column 53 moves upward and under the pressure of the spring 54, the upper end of the sealing member 55 abuts against the inner wall of the suction cup 31 to form a sealing structure, thereby preventing the suction cup 31 from leaking and failing to adsorb the steel plate.

[0029] Furthermore, in the present embodiment, a connector 6 which cooperates with the protective plate 52 is fixedly provided on the connecting column 53, a through hole is opened on the cross plate 51, a support column 7 which cooperates with the through hole is fixedly provided on the upper end of the connector 6, and a limiter 8 which cooperates with the through hole is provided on the support column 7. The connecting column 53 is connected to the cross plate 51 by providing the support column 7, and the connecting column 53 is fixed by providing the limiter 8 to prevent the connecting column 53 from being separated from the cross plate 51. In the present embodiment, the connector 6 is a non-circular structure, such as a polygon such as a rectangle or a triangle.

[0030] It should be noted that, in this embodiment, the limit member 8 includes a rotating part 81 rotatably connected to the support column 7, the outer wall of the rotating part 81 is fixedly provided with a limit part 82 corresponding to the through hole, and the top of the support column 7 is also provided with a capping top corresponding to the rotating part 81 to prevent the limit member 8 from separating from the support column 7.

[0031] In addition, in the present embodiment, a guide groove 83 cooperating with the limiting portion 82 is formed on the inner wall of the through hole, and the guide groove 83 is a spiral structure. When the limiting member 8 corresponds to the guide groove 83 in the through hole, the limiting portion 82 will rotate when moving upward, and when the support column 7 is fully plugged into the through hole, the limiting portion 82 is rotated, and the lower surface of the limiting portion 82 contacts the upper surface of the cross plate 51, thereby limiting the position of the support column 7 and preventing it from being separated from the through hole.

[0032] In more detail, in this embodiment, a torsion spring 9 is connected to the support column 7, and the other end of the torsion spring 9 is connected to the limit member 8, so that the limit member 8 corresponds to the guide groove 83 in the through hole. When moving upward, the limit part 82 will rotate, and the torsion spring 9 will undergo elastic deformation. When the support column 7 is fully plugged into the through hole, the limit part 82 is separated from the through hole. Under the action of the torsion spring, the limit part 82 rotates and is misaligned with the guide groove 83, thereby limiting the position of the support column 7 and preventing it from being separated from the through hole.

[0033] Working mode: When working, the hoisting frame 4 is driven to move upward by the hoisting mechanism 2, and moves along the bracket 1 to the top of the steel plate, and the hoisting frame 4 is moved down until the suction cup 31 contacts the steel plate. At this time, the suction cup 31 stops moving downward due to the force, and the connecting column 53 will still move downward under the action of inertia, and the pressure generated by the downward movement of the connecting column 53 and the impact force generated by the suction cup 31 contacting the steel plate are absorbed by the deformation of the spring 54, and the steel plate is adsorbed by the suction cup 31, and the hoisting frame 4 and the steel plate are driven to move upward by the hoisting mechanism 2, and the steel plate is lowered after moving along the bracket 1 to the desired position;

[0034] The limiting member 8 is matched with the guide groove 83 in the through hole. When moving upward, the limiting part 82 will rotate. At this time, the torsion spring 9 will undergo elastic deformation. When the support column 7 is fully plugged into the through hole, the limiting part 82 will separate from the through hole. Under the action of the torsion spring, the limiting part 82 will rotate and be misaligned with the guide groove 83, thereby limiting the position of the support column 7 and making it unable to separate from the through hole. The plug-in member 6 is provided to prevent the support column 7 from rotating and driving the limiting part 82 to rotate.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
