[0025] Please see Figure 1-4 This utility model provides a technical solution: a brake for tire production, comprising:

[0026] The base 100 is used to mount the tire lifting platform 200 and the hydraulic cylinder 300;

[0027] The braking assembly 400 is used to lock the tire lifting platform 200 after it is driven to rise and fall by the hydraulic cylinder 300. The braking assembly 400 includes four fixed cylinders 401 fixed in a circumferential array on the upper surface of the base 100, and telescopic rods 402 slidably disposed on the inner walls of the four fixed cylinders 401 respectively. The top end of the telescopic rod 402 is fixedly connected to the lower surface of the tire lifting platform 200, and the surface of the telescopic rod 402 is provided with straight toothed grooves 403. The braking assembly 400 also includes a hollow ring 404 fixed on the outer surface of the four fixed cylinders 401, and toothed plates 405 slidably disposed in a circumferential array on the inner wall of the hollow ring 404 and corresponding to the four straight toothed grooves 403 respectively. A drive motor 406 is fixed on the upper surface of the hollow ring 404 for driving the four toothed plates 405 to mesh with the four straight toothed grooves 403 at the same time.

[0028] See Figure 2 , Figure 3 The hollow ring 404 and the fixed cylinder 401 have sliding openings for the toothed plate 405 to slide, and the toothed plate 405 has an internal threaded cylinder 407 fixed on its surface, and the internal threaded cylinder 407 is slidably connected to the inner wall of the sliding opening.

[0029] Specifically, by setting the internal threaded cylinder 407, the toothed plate 405 can be moved by the extension and retraction of the internal threaded cylinder 407.

[0030] See Figure 3The inner wall of the hollow ring 404 is provided with four threaded posts 408 arranged in a circumferential array, and the outer surfaces of the four threaded posts 408 are respectively threaded to the inner walls of the four internal threaded cylinders 407.

[0031] Specifically, by setting the threaded post 408, the rotation of the threaded post 408 can drive the internal threaded cylinder 407 to automatically extend and retract.

[0032] See Figure 3 , Figure 4 A connecting ring 409 is rotatably provided on the inner top wall of the hollow ring 404, and a bevel gear ring 4010 is fixed on the inner ring surface of the connecting ring 409. A driven bevel gear 4011 is fixed on the surface of each of the four threaded columns 408, and the four driven bevel gears 4011 mesh with the inner wall of the bevel gear ring 4010.

[0033] Specifically, by setting a bevel gear ring 4010 and a driven bevel gear 4011, the rotation of the connecting ring 409 can drive the four threaded columns 408 to rotate simultaneously.

[0034] See Figure 3 , Figure 4 The output end of the drive motor 406 extends into the interior of the hollow ring 404 and is fixedly provided with the drive gear 4012, and the inner ring surface of the connecting ring 409 is fixedly provided with the driven gear ring 4013 that meshes with the drive gear 4012.

[0035] Specifically, by setting the active gear disc 4012 and the driven gear ring 4013, the connecting ring 409 can be driven to rotate at a reduced speed by the rotation of the drive motor 406.

[0036] See Figure 3 The inner wall of the hollow ring 404 is fixed with four limiting rods 4014 corresponding to the four internal threaded cylinders 407 in a circumferential array, and the end of the internal threaded cylinder 407 is fixed with a limiting block 4015. The surface of the limiting block 4015 is provided with a sliding hole that is slidably connected to the surface of the limiting rod 4014.

[0037] Specifically, by setting the limit block 4015 and the limit rod 4014, the stability of the internal threaded cylinder 407 during its movement can be effectively guaranteed.

[0038] In this invention, by setting a braking component 400, after the tire lifting platform 200 is driven to rise and fall to a suitable position by the hydraulic cylinder 300, the drive motor 406 can be started, which drives the toothed plate 405 into the straight tooth groove 403 and meshes with the straight tooth groove 403, thereby effectively limiting the telescopic rod 402 and effectively braking the tire lifting platform 200 after lifting and falling, ensuring the stability during tire processing and ensuring the service life of the hydraulic cylinder 300.

[0039] Working principle: After the tire lifting platform 200 is lifted to a suitable position by the hydraulic cylinder 300, the drive motor 406 is started. The rotation of the drive motor 406 drives the active gear plate 4012 to rotate. The rotation of the active gear plate 4012 drives the driven gear ring 4013 and the connecting ring 409 to rotate. The rotation of the connecting ring 409 drives the bevel gear ring 4010 to rotate. The rotation of the bevel gear ring 4010 drives the four driven bevel gears 4011 to rotate. The rotation of the four driven bevel gears 4011 drives the four threaded columns 408 to rotate simultaneously. The rotation of the threaded columns 408 drives the internal threaded cylinder 407 to move inward, thereby driving the tooth plate 405 to enter the straight tooth groove 403 and mesh with the straight tooth groove 403, realizing the effective limit of the telescopic rod 402, and thus realizing the effective braking of the tire lifting platform 200 after lifting, ensuring the stability during tire processing and ensuring the service life of the hydraulic cylinder 300.

[0040] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
