DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Example 1

[0022] As shown in the attached Figures 1 to 4 An omnidirectional adjustable trolley tensioning oil cylinder bracket, including a rotating base 1 and a swinging assembly 4. A support base 2 is installed above the rotating base 1, and the swinging assembly 4 is arranged on the side of the support base 2 away from the rotating base 1. A tensioning oil cylinder 3 is arranged on the side of the swinging assembly 4 away from the support base 2. The swinging assembly 4 includes a main rotating bracket 19, a sub-rotating bracket 17 and a mounting plate 9. A sub-rotating bracket 17 is arranged on the right side of the main rotating bracket 19. Mounting plates 9 are installed below both the main rotating bracket 19 and the sub-rotating bracket 17 through bolts.

[0023] Among them: When the tensioning oil cylinder 3 is in use, since the fixing of the tensioning oil cylinder 3 only allows adjustment in a specific direction, this also limits the use of the tensioning oil cylinder 3 in a complex environment. Therefore, by installing the tensioning oil cylinder 3 on the swinging assembly 4, the area of the output end of the tensioning oil cylinder 3 can be adjusted, enabling the tensioning oil cylinder 3 to adjust the output range in a complex environment, so that the tensioning oil cylinder 3 can adjust the position of use at any time. Then, the swinging assembly 4 for connecting the tensioning oil cylinder 3 is installed above the rotating base 1, so that the rotating base 1 drives the support base 2, thereby changing the output position of the tensioning oil cylinder 3, so that when the tensioning oil cylinder 3 is in use, the use position of the tensioning oil cylinder 3 can be adjusted according to the usage situation at any time. Example 2

[0024] Based on Example 1, the solution in Example 1 will be further refined and introduced in combination with the following specific working methods, as Figures 1 to 4 shown, for details see the following description:

[0025] As a preferred implementation method, the sub-rotating bracket 17 includes a fixing block 14, a docking bracket 15 and a connecting bracket 16. A docking bracket 15 is arranged at the center of the two fixing blocks 14, and a connecting bracket 16 is arranged on the side of the docking bracket 15 away from the fixing block 14. When adjusting the tensioning oil cylinder 3, the connecting brackets 16 of the main rotating bracket 19 and the sub-rotating bracket 17 are connected to the tensioning oil cylinder 3 at the same time, and then the connecting brackets 16 of the two are installed on the connecting bracket 16 and the tensioning oil cylinder 3 through the fixing block 14, thereby completing the fixing of the tensioning oil cylinder 3. The connecting bracket 16 is placed inside the docking bracket 15, so that the docking bracket 15 limits the connecting bracket 16.

[0026] As a preferred embodiment, the structures between the main rotating bracket 19 and the secondary rotating bracket 17 are the same. A rotating shaft 18 is provided at the centers of the main rotating bracket 19 and the secondary rotating bracket 17. A fixing ring 1801 is provided on the side of the rotating shaft 18 away from the main rotating bracket 19. A rotating gear 20 is provided on the side of the main rotating bracket 19 away from the rotating shaft 18. Both the main rotating bracket 19 and the secondary rotating bracket 17 rotate through the rotating shaft 18. The connection between the rotating shaft 18 and the secondary rotating bracket 17 is connected through the fixing ring 1801 to increase the contact area between the secondary rotating bracket 18 and the rotating shaft 1801. A bearing is installed inside the fixing ring 1801 to facilitate the rotating shaft to drive the connecting bracket 16 of the secondary rotating bracket 17 to rotate. The rotating gear 20 installed on the side of the main rotating bracket 19 is used to connect with the speed reducer 22.

[0027] As a preferred embodiment, a partition plate 21 is provided on the side of the rotating gear 20 away from the main rotating bracket 19. A speed reducer 22 is installed on one side of the partition plate 21. A servo motor 23 is installed below the speed reducer 22. When rotating the rotating shaft 18, the servo motor 23 drives the speed reducer 22 to rotate at this time, and then the speed reducer 22 drives the rotating gear 20 to rotate, thereby driving the rotating shaft 18 to rotate. The partition plate 21 is used to connect with one end of the rotating shaft 18. A bearing is installed at the connection between the partition plate 21 and the rotating shaft 18 to reduce the friction of the rotating shaft 18 during rotation by the bearing. An electromagnetic brake is installed inside the servo motor 23, which is realized by the electromagnetic brake. When the motor receives a stop command and cuts off the current, the electromagnetic brake is activated, generating a magnetic force to attract the iron core inside the brake, thereby generating friction to lock the motor shaft and prevent the shaft from rotating.

[0028] As a preferred embodiment, the tensioning oil cylinder 3 includes a tensioning base 10, a mounting bracket 11, a spring 12 and a push rod 13. A mounting bracket 11 is provided on the side of the tensioning base 10 away from the servo motor 23. A spring 12 is provided on the side of the mounting bracket 11 away from the tensioning base 10. Push rods 13 are placed on both sides of the inner wall of the spring 12. The tensioning base 10 is installed in the tensioning oil cylinder 3, and then the end part of the oil cylinder is installed with the mounting bracket 11. The tensioning oil cylinder 3 passes through the spring 12 and the push rod 13. The functions of the spring 12 and the push rod 13 in the tensioning oil cylinder 3 are to provide tension and compensation. The spring 12 maintains a certain pre-tightening force when the oil cylinder is not subjected to external pressure, ensuring that the oil cylinder can effectively tighten or pull related components during operation.

[0029] As a preferred embodiment, the rotating base 1 includes a fixed bracket 5, a connecting disk 6, a sealing ring 7, and a rotating head 8. The connecting disk 6 is installed on both sides of the inner wall of the fixed bracket 5. The sealing ring 7 is installed above the inner wall of the connecting disk 6. The rotating head 8 is installed above the sealing ring 7. When the tensioning oil cylinder 3 needs to be turned, the support base 2 is installed on the rotating head 8 of the rotating base 1. When the motor drives the rotating head 8 to rotate, the support base 2 installed on the rotating head 8 drives the tensioning oil cylinder 3 to rotate.

[0030] The working process of the present utility model is as follows: When adjusting the tensioning oil cylinder 3, the connecting bracket 16 of the main rotating bracket 19 and the auxiliary rotating bracket 17 is simultaneously connected to the tensioning oil cylinder 3 at this time. Then, the connecting bracket 16 of the two is installed on the connecting bracket 16 and the tensioning oil cylinder 3 through the fixing block 14, thereby completing the fixation of the tensioning oil cylinder 3. The connecting bracket 16 is placed inside the docking bracket 15, so that the docking bracket 15 limits the connecting bracket 16. Both the main rotating bracket 19 and the auxiliary rotating bracket 17 rotate through the rotating shaft 18. The connection between the rotating shaft 18 and the auxiliary rotating bracket 17 is connected through the fixing ring 1801 to increase the contact area between the auxiliary rotating bracket 18 and the rotating shaft 1801. A bearing is installed inside the fixing ring 1801 to facilitate the rotating shaft to drive the connecting bracket 16 of the auxiliary rotating bracket 17 to rotate. The rotating gear 20 installed on the side of the main rotating bracket 19 is used to connect to the speed reducer 22. When rotating the rotating shaft 18, the servo motor 23 drives the speed reducer 22 to rotate at this time, and then the speed reducer 22 drives the rotating gear 20 to be installed, thereby driving the rotating shaft 18 to rotate. The partition plate 21 is used to connect to one end of the rotating shaft 18. A bearing is installed at the connection between the partition plate 21 and the rotating shaft 18 to reduce the friction of the rotating shaft 18 during rotation by the bearing. An electromagnetic brake is installed inside the servo motor 23, which is achieved by the electromagnetic brake. When the motor receives a stop command and the current is cut off, the electromagnetic brake is activated, generating a magnetic force to attract the iron core inside the brake, thereby generating a frictional force to lock the motor shaft and prevent the shaft from rotating. A tensioning base 10 is installed in the tensioning oil cylinder 3, and then the end part of the oil cylinder is installed on the mounting bracket 11. The tensioning oil cylinder 3 is connected through the spring 12 and the ejector rod 13. The functions of the spring 12 and the ejector rod 13 in the tensioning oil cylinder 3 are to provide tension and compensation. The spring 12 maintains a certain pre-tightening force when the oil cylinder is not subjected to external pressure, ensuring that the oil cylinder can effectively tighten or pull related components during the working process. When the tensioning oil cylinder 3 needs to turn, the support base 2 is installed on the rotating head 8 of the rotating base 1 at this time. When the motor drives the rotating head 8 to rotate, the support base 2 installed on the rotating head 8 drives the tensioning oil cylinder 3 to rotate. The above is the working principle of the omnidirectional adjustable trolley tensioning oil cylinder bracket.

[0031] Finally, the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
