Description

Technical Field

[0001] This utility model relates to the field of cage winch technology, and in particular to a transmission structure for a cage winch. Background Technology

[0002] A cage stranding machine is a device used in wire and cable factories to strand control cables, rubber cables, steel strands, steel-cored aluminum strands, copper strands, aluminum strands, and flexible strands. The working principle of a cage stranding machine is to use the rotation of multiple small cages to simultaneously or separately strand multiple wires. Each small cage can hold one or more wires to be stranded. When the central shaft rotates, the small cages also rotate, and the wires inside move relative to the cages due to friction, thus achieving stranding.

[0003] The existing transmission structure of the cage winch consists of a motor, a reducer, and a transmission assembly. The transmission shaft on the transmission assembly is directly integrally formed and fixed to the main shaft on the cage winch. When the transmission assembly fails, it is difficult to disassemble and assemble the transmission shaft and the main shaft on the cage winch, which affects the convenience of disassembly, assembly, and maintenance of the motor drive end and the main body of the cage winch.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] This utility model provides, for example Figure 1-4 The transmission structure of the cage winch shown includes:

[0046] The system comprises a support base 1, a stranding mechanism 2, a drive mechanism 3, and a connecting mechanism 4. The stranding mechanism 2 is mounted on the top of the support base 1, and the drive mechanism 3 is mounted on one end of the stranding mechanism 2. The drive mechanism 3 includes a servo motor 31, a reducer 32, a connecting shaft assembly 33, and a positioning assembly 34. The reducer 32 is mounted on the output end of the servo motor 31, and the connecting shaft assembly 33 is detached from the stranding mechanism 2 through the positioning assembly 34. The connecting mechanism 4 is mounted between the stranding mechanism 2 and the drive mechanism 3, and is used for the synchronous stranding of multiple wires in the stranding mechanism 2.

[0047] The stranding mechanism 2 includes a stranding machine body 21, a stranding cage 22, a cage shaft 23, and a main shaft assembly 24. The stranding machine body 21 is connected to the top of the support base 1 through a support frame. Multiple stranding cages 22 are installed in a circular array in the middle of the stranding machine body 21. The cage shaft 23 is fixed to the end of the stranding cage 22. The cage shaft 23 enables the stranding cage 22 to rotate on the stranding machine body 21. The main shaft assembly 24 is fixedly inserted in the middle of the stranding machine body 21. The rotation of the main shaft assembly 24 can drive the stranding machine body 21 to rotate.

[0048] Specifically, the spindle assembly 24 includes: a spindle body 241, a mating block 242, a connecting hole 243, and a positioning hole 244. The spindle body 241 is fixedly inserted into the end of the stranding machine body 21. The mating block 242 is integrally formed and disposed at one end of the spindle body 241. The connecting hole 243 is opened in the middle of the mating block 242, and the positioning hole 244 is opened in the middle of the mating block 242.

[0049] Furthermore, the connecting shaft assembly 33 includes: a drive shaft 331, a mating groove 332, and a rectangular block 333. The drive shaft 331 is connected to the servo motor 31 via a reducer 32, so that the drive of the servo motor 31 can drive the drive shaft 331 to rotate stably. Two adjacent positioning components 34 are arranged opposite to each other at the ends of the drive shaft 331. The mating groove 332 is opened at one end of the drive shaft 331 and is inserted into one end of the mating block 242. The rectangular block 333 is integrally formed and fixed in the inner cavity of the mating groove 332 and is inserted into the inner cavity of the connecting hole 243. Through the insertion between the drive shaft 331 and the main shaft body 241, the opposite ends of the drive shaft 331 and the main shaft body 241 form a mating snap-fit ​​structure. The connection between the drive shaft 331 and the main shaft body 241 is reinforced by the positioning components 34, so that the drive shaft 331 can drive the main shaft body 241 to rotate stably.

[0050] Furthermore, the positioning assembly 34 includes: a positioning rod 341, a magnetic block 342, a handle 343, a tension spring 344, and a locking block 345. The positioning rod 341 is slidably inserted into the end of the drive shaft 331. The magnetic block 342 is fixed to one end of the positioning rod 341. The positioning rod 341 passes through the mating block 242 and is slidably inserted into the middle of the rectangular block 333. The magnetic blocks 342 at opposite ends of the two positioning rods 341 are magnetically connected, stabilizing the position of the two positioning rods 341 and preventing the positioning rods 341 from disengaging from the drive shaft 331 due to rotation. The handle 343 is fixed. At the other end of the positioning rod 341, the tension spring 344 is fixed to one end of the handle 343. The tension spring 344 is slidably inserted into the inner wall of the mating groove 332. The locking block 345 is fixedly connected to one end of the tension spring 344. The locking block 345 is inserted into the inner wall of the mating groove 332. The handle 343 is movably attached to the outer wall of the drive shaft 331. By pulling the handle 343 forcefully, the two magnetic blocks 342 at opposite ends of the two positioning rods 341 can be separated, so that the positioning rods 341 can release the insertion limit between the drive shaft 331 and the main shaft body 241, making the disassembly and assembly between the drive shaft 331 and the main shaft body 241 convenient.

[0051] In addition, the connecting mechanism 4 includes: a protective disc 41, a first gear 42, a connecting gear 43, and a second gear 44. The protective disc 41 is fixed to one end of the stranding machine body 21 by bolts. The first gear 42 is fixed to one end of the main shaft assembly 24. The connecting gear 43 meshes with the outer wall of the first gear 42. Multiple second gears 44 are respectively fixedly connected to one end of multiple cage shafts 23 that rotate through the stranding machine body 21. The connecting gear 43 is synchronously meshed with the outer walls of the multiple second gears 44. By disassembling and assembling the connecting gear 43 with the first gear 42 and the second gear 44, the first gear 42 can rotate independently and the second gear 44 can rotate simultaneously, so that the cable on the stranding cage 22 can rotate to achieve the simultaneous or separate stranding of multiple wires.
