[0025] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0026] In the specific implementation process, Figures 1 to 6 As shown, the belt transmission anti-loosening tensioning device for super gravity equipment provided by the utility model comprises an equipment support assembly 1, a motor 2 is fixedly arranged on one side of the equipment support assembly 1, a tensioning mechanism is arranged on the top of one side of the equipment support assembly 1, and a transmission belt 3 is sleeved on the equipment support assembly 1, the output end of the motor 2 and the outer side of the tensioning mechanism;

[0027] The tensioning mechanism includes a fixed part fixedly connected to the top of the equipment support assembly 1 and a rotating part in contact with the transmission belt 3, and the fixed part is used to push the rotating part to contact the transmission belt 3;

[0028] A plurality of conical claws 12 are arranged in a circular array inside the fixing piece, and a plurality of sliding pieces are arranged through the plurality of conical claws 12 along the conveying direction of the fixing piece, and the sliding pieces are in contact with the inner side wall of the fixing piece.

[0029] The multiple conical claws 12 arranged in a circular array in the fixed part form a dynamic tensioning system through the interaction with the rotating part in contact with the transmission belt 3. When the belt needs to adjust the tension due to relaxation, wear or load changes during the operation of the equipment, the fixed part can accurately push the rotating part to fit the belt to achieve tensioning. The structural design of the conical claws 12 is conducive to evenly dispersing the pressure during the pushing process, avoiding excessive local force on the belt and protecting the belt from damage. Multiple sliding parts are arranged along the conveying direction of the fixed part. They fit tightly with the inner wall of the fixed part, which not only ensures smooth movement during the tensioning process, but also can automatically adapt to the slight changes of the transmission belt 3 through its own sliding adjustment, ensuring the uniform distribution of tensioning force, making the tensioning process more flexible and accurate, reducing the vibration and noise caused by uneven belt tensioning, and improving the stability of equipment operation.

[0030] Through the linkage between the output end of motor 2 and the tensioning mechanism, it can respond quickly according to the actual operating conditions and automatically adjust the tensioning state without frequent manual intervention, which greatly improves work efficiency and reduces maintenance costs. When adjustment or maintenance is required, the operator can easily check and adjust the tensioning mechanism;

[0031] The structural design of the fixed part and the rotating part, combined with the cooperation of the conical claw 12 and the sliding part, improves the stability of the tensioning device, ensures durability under long-term and high-intensity working conditions, reduces the risk of belt slippage and falling off, and extends the service life of the belt and the entire transmission system.

[0032] The fixing part includes an adapter part 4 installed on the outside of the equipment support assembly 1 and a pushing part 9 that fits with the rotating part. The adapter part 4 is arranged through the inner wall of the pushing part 9; the inner wall of the adapter part 4 is threadedly connected with a supporting rod 5, and the supporting rod 5 is provided with a parallel groove 6. The outer surface of the supporting rod 5 is provided with a threaded part and a smooth part. The outer wall of the supporting rod 5 is provided with parallel grooves 6 in an annular array, and the outer surface of the supporting rod 5 is respectively provided with an adjusting nut 7 and a spring 8. The adjusting nut 7 can squeeze the spring 8 on the threaded part to apply a pushing force to the pushing part 9; the inner wall of the pushing part 9 is provided with a tapered groove 10, and the end of the tapered groove 10 away from the transmission belt 3 is the large diameter end, and the inner wall of the pushing part 9 is also in an annular array. The row is provided with an oblique groove 11 parallel to and connected with the conical groove 10, the support rod 5 penetrates and extends out of the inner wall of the pushing part 9, the conical claw 12 is placed in the conical groove 10 of the pushing part 9, and the ends of multiple conical claws 12 are joined to form a conical profile. The conical claw 12 is also provided with a through groove 13, and the sliding member includes two fixed shafts 16 rods 14 and two sliding rollers 15. The two fixed shafts 16 rods 14 are respectively rotatably connected to the through grooves 13 of the conical claws 12, and the sliding rollers 15 are fixedly connected to the outer surface of the fixed shafts 16 rods 14, and the two sliding rollers 15 extend out of the conical claws 12 and respectively fit with the oblique groove 11 of the pushing part 9 and the parallel groove 6 of the support rod 5;

[0033] The structural design of the adapter 4 and the pusher 9 realizes precise adjustment of the thrust of the pusher 9 through the cooperation between the threaded portion on the support rod 5 and the adjusting nut 7. When the adjusting nut 7 rotates, the spring 8 is squeezed to generate a thrust to the pusher 9, and then the pusher 9 acts on the rotating part to achieve tensioning of the transmission belt 3, so that the tensioning force can be fine-tuned according to actual needs, thereby improving the accuracy and flexibility of tensioning;

[0034] The conical profile of the conical claw 12 and the through groove 13 not only increase the contact area with the support rod 5 and the push part 9 to ensure the uniform distribution of the tensioning force, but also realize the guidance and stable support of the support rod 5 through the cooperation of the fixed shaft 16 rod 14 and the sliding roller 15. The sliding roller 15 rolls in the oblique groove 11 and the parallel groove 6 of the support rod 5, ensuring that the push part 9 is stable and free of jams during the pushing process, while reducing friction loss and improving the service life of the device;

[0035] The rolling of the sliding roller 15 cooperates with the oblique groove 11 of the pushing part 9 and the parallel groove 6 of the supporting rod 5. When the transmission belt 3 becomes loose due to elongation or load changes during use, the elastic restoring force of the spring 8 and the position fine-tuning of the adjusting nut 7 can quickly respond and restore the tension state of the belt to maintain the stability of the transmission system.

[0036] The rotating part includes a fixed shaft 16 fixedly connected to the top of the equipment support assembly 1, and a tensioning arm 17 is rotatably connected to the fixed shaft 16. A tensioning wheel 18 for pushing the transmission belt 3 to be tensioned is rotatably connected between the tensioning arms 17. One side of the tensioning arm 17 is arranged in contact with the pushing part 9, and the pushing part 9 can push the tensioning arm 17 to rotate along the fixed shaft 16 as the center to extrude the transmission belt 3.

[0037] When the pushing portion 9 applies a thrust to the tensioning arm 17, the tensioning arm 17 rotates along the fixed axis 16 and directly acts on the tensioning wheel 18, thereby applying appropriate tension to the transmission belt 3 to achieve dynamic adjustment. The tensioning wheel 18 rotatably connected between the tensioning arms 17 directly contacts the transmission belt 3, ensuring that the tensioning force can be transmitted to the belt with almost no loss, avoiding the belt from loosening during operation, and improving the stability and efficiency of the transmission. The position design of the tensioning wheel 18 ensures uniform compression of the belt, reduces local stress concentration, and extends the service life of the belt. The rotation angle of the tensioning arm 17 is accurately controlled by the movement of the pushing portion 9, thereby adjusting the size of the tensioning force and improving the response speed and accuracy.
