Description

Technical Field

[0001] This utility model relates to the field of cable stranding machine technology, and in particular to a three-dimensional tension balance wheel group structure for a cable stranding machine. Background Technology

[0002] A stranding machine is a type of mechanical equipment that can be widely used to strand various soft and hard conductor wires, turning multiple single conductors into one strand to meet the process requirements of wire. Stranding machines can generally be classified according to the stranding method into single stranding machines, double stranding machines, high-speed stranding machines, untwisting machines, cage stranding machines, frame stranding machines, tubular stranding machines, and disc stranding machines, including cable stranding machines.

[0003] In existing technologies, when using a cable stranding machine to strand cables, a tension balancing wheel assembly is essential to ensure cable balance. Currently, the balancing wheel assemblies on existing cable stranding machines are directly fixed to the rotating shaft with bolts. This installation method makes it inconvenient to align the bolts with the bolt holes during installation, wasting time and effort and reducing the installation speed of the balancing wheel assembly. Furthermore, because the tension wheel is fixed in a fixed position, the balancing wheel assembly cannot adaptively adjust the cable tension. When the cable vibrates during stranding, it is prone to falling off the balancing wheel assembly, affecting the normal operation of the cable stranding machine and slowing down the cable stranding process. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a three-dimensional tension balance wheel structure for cable stranding machines.

Mounting bolts are threadedly connected to the four ends of the sidewall of the mounting plate, the mounting bolts penetrating the mounting plate. Two rotating rods are rotatably connected to the sidewall of the mounting plate. The two tension wheels are respectively sleeved on the outer surface of the corresponding rotating rods. A fixing plate is fixedly installed on the outer surface of the rotating rod located between the mounting plate and the tension wheels.

[0009] The outer surface of the fixed sleeve is threaded with four fixing bolts, all of which penetrate the outer surface of the fixed sleeve and are inserted into the outer surface of the rotating rod.

[0010] As a further description of the above technical solution:

[0011] Four connecting rods are fixedly installed on the side wall of the fixed plate. The connecting rods pass through the tension wheel, the pressure plate and the mounting ring in sequence. Nuts are fitted on the outer surface of the end of the four connecting rods away from the fixed plate. Threaded grooves are opened on the outer surface of the end of the connecting rod away from the fixed plate. The connecting rods are threadedly connected to the nuts through the threaded grooves.

Detailed Implementation

[0028] 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.

[0029] Reference Figures 1 to 5 This utility model provides a three-dimensional tension balancing wheel assembly structure for a cable stranding machine: it includes a mounting plate 1 and two tension wheels 2. The two tension wheels 2 are both located on the outer side of the mounting plate 1. Mounting bolts 3 are threadedly connected to the four ends of the side wall of the mounting plate 1. The mounting bolts 3 penetrate the mounting plate 1. Two rotating rods 4 are rotatably connected to the side wall of the mounting plate 1. The two tension wheels 2 are respectively sleeved on the outer surface of the corresponding rotating rods 4. A fixing plate 5 is fixedly installed on the outer surface of the rotating rod 4 located between the mounting plate 1 and the tension wheels 2. A fixing sleeve 7 is sleeved on the outer surface of the rotating rod 4 at the end away from the mounting plate 1. A mounting ring 8 is fixedly installed on the end of the fixing sleeve 7 near the tension wheel 2. Several damping springs 9 are fixedly installed on the side wall of the mounting ring 8 near the tension wheel 2. A pressure plate 10 is fixedly installed on the end of the damping springs 9 away from the mounting ring 8.

[0030] To facilitate quick and easy fixation of the fixed sleeve 7, limit blocks 11 are fixedly installed on the inner walls of the tension wheel 2, the fixed sleeve 7, the mounting ring 8, and the pressure plate 10. The outer surface of the rotating rod 4 is provided with a limit groove that slides and connects with the limit block 11. Four fixing bolts 12 are threadedly connected to the outer surface of the fixed sleeve 7. All four fixing bolts 12 penetrate the outer surface of the fixed sleeve 7 and are inserted into the outer surface of the rotating rod 4. Four connecting rods 6 are fixedly installed on the side wall of the fixed plate 5. The connecting rods 6 pass through the tension wheel 2, the pressure plate 10, and the mounting ring 8 in sequence. Nuts 13 are fitted on the outer surface of the four connecting rods 6 at the end away from the fixed plate 5. Threaded grooves are provided on the outer surface of the connecting rods 6 at the end away from the fixed plate 5. The connecting rods 6 are threadedly connected to the nuts 13 through the threaded grooves.

[0031] By setting up mounting plate 1, tension wheel 2, mounting bolt 3, rotating rod 4, fixing plate 5, connecting rod 6, fixing sleeve 7, mounting ring 8, damping spring 9, pressure plate 10, limit block 11, fixing bolt 12, and nut 13, the function of quickly and conveniently installing tension wheel 2 is realized. This improves the installation method of the balance wheel group in the existing technology, saving time and effort when installing tension wheel 2, increasing the installation speed of tension wheel 2, and enabling the balance wheel group to adaptively adjust the tension of the cable. When the cable vibrates, tension wheel 2 can move with the vibration of the cable, thereby preventing the cable from falling out of the balance wheel group, ensuring the normal use of the cable stranding machine, and improving the working progress of cable stranding.

[0032] Two rotating rods 4 are equipped with a reduction gear assembly, which includes a reduction disc 14. The reduction disc 14 is fixedly installed on the outer surface of the rotating rod 4. An electric telescopic rod 15 is fixedly installed on the outer surface of the mounting plate 1. An mounting sleeve 16 is fixedly installed at the output end of the electric telescopic rod 15. A reduction block 17 is slidably connected to the inner wall of the mounting sleeve 16. The arc-shaped inner wall of the reduction block 17 is adapted to the circular outer wall of the reduction disc 14. A locking block 18 is fixedly installed on the inner wall of the mounting sleeve 16. A locking groove 19 is opened on the outer surface of the reduction block 17. Both the locking block 18 and the locking groove 19 are T-shaped. The locking block 18 and the inner wall of the locking groove 19 are slidably connected. Two limiting bolts 20 are threadedly connected to the side wall of the mounting sleeve 16 near the electric telescopic rod 15. The limiting bolts 20 penetrate the side wall of the mounting sleeve 16 and extend into the interior of the mounting sleeve 16. The limiting bolts 20 are inserted into the reduction block 17.

[0033] By setting up a speed reducer 14, an electric telescopic rod 15, a mounting sleeve 16, a speed reduction block 17, a locking block 18, a locking groove 19, and a limiting bolt 20, the function of limiting the rotation speed of the rotating rod 4 is realized. By limiting the rotation speed of the rotating rod 4, the rotation speed of the tension wheel 2 is limited, thereby preventing the cable from falling off due to the excessive rotation speed of the tension wheel 2. On the original basis, the practicality of the balance wheel set is further improved.

[0034] Working principle: When installing the balance wheel assembly, first, the four mounting bolts 3 fix the mounting plate 1 onto the stranding machine. Then, bring the tension wheel 2 close to the rotating rod 4, so that the limiting block 11 on the inner wall of the tension wheel 2 aligns with the limiting groove. Move the tension wheel 2 to fit onto the outer surface of the rotating rod 4, so that the limiting block 11 slides into the limiting groove. When the tension wheel 2 contacts the side wall of the fixing plate 5, the connecting rod 6 penetrates the tension wheel 2. Then, in the same way, the fixing sleeve 7 is fitted onto the outer surface of the rotating rod 4, thereby stabilizing the tension wheel assembly. The mounting ring 8 and the pressure plate 10 are fitted onto the outer surface of the rotating rod 4, so that the side wall of the pressure plate 10 is in contact with the tension wheel 2. At the same time, the connecting rod 6 passes through the pressure plate 10 and the mounting ring 8. Then, the fixing bolt 12 is turned so that the fixing bolt 12 passes through the outer surface of the fixing sleeve 7 and is turned into the rotating rod 4 to fix the fixing sleeve 7. Finally, the nut 13 is screwed onto the connecting rod 6 through the thread groove, so that the nut 13 abuts against the mounting ring 8 to complete the installation of the tension wheel 2. The above operation is repeated to install the other tension wheel 2.

[0035] After the balance wheel assembly is installed, bring the reduction block 17 close to the mounting sleeve 16 so that the reduction block 17 is aligned with the inside of the mounting sleeve 16 and the locking block 18 is aligned with the locking groove 19. Move the reduction block 17 so that it slides into the inside of the mounting sleeve 16 and the locking block 18 slides into the inside of the locking groove 19. At this time, the reduction block 17 is connected to the mounting sleeve 16. Then, tighten the limiting bolt 20 so that the limiting bolt 20 passes through the side wall of the mounting sleeve 16 and rotates into the reduction block 17 to fix the reduction block 17 and complete the installation of the reduction block 17. Repeat the above operation to install the other reduction block 17.

[0036] When using a cable stranding machine to strand cables, the cable slides inside the tension wheel 2, thereby driving the tension wheel 2 and the rotating rod 4 to rotate. When the cable vibrates, the cable drives the tension wheel 2 to slide on the outer surface of the rotating rod 4 and the connecting rod 6, while simultaneously driving the pressure plate 10 to move, causing the damping spring 9 to compress and deform. When the damping spring 9 returns to its original position, the pressure plate 10 presses down on the tension wheel 2, causing the tension wheel 2 to return to its original position. In this process, on the one hand, it can prevent the cable from falling out of the tension wheel 2, and on the other hand, it can buffer the force generated by the cable vibration, thereby reducing the vibration amplitude of the cable.

[0037] When the speed of tension wheel 2 and rotating rod 4 is too fast, the electric telescopic rod 15 is activated and extended. This causes the speed reduction block 17 to move towards the speed reduction disc 14 via the mounting sleeve 16. When the inner wall of the speed reduction block 17 contacts the outer circular wall of the speed reduction disc 14, the speed of rotating rod 4 is limited by the speed reduction disc 14, thereby limiting the speed of tension wheel 2.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
