DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Embodiment 1: Figure 1 - Figure 7 As shown, a casing pay-off stand with online adjustable tension in the figure comprises a base 1, a bracket 2 is fixedly connected to the top of the base 1, a top seat 3 is fixedly connected to the top of the bracket 2, the base 1, the bracket 2 and the top seat 3 are all welded, and also comprise: a pulley 34 and a fixed wheel 4 rotatably connected to the outside of the base 1 and the top seat 3 respectively, the outside of the pulley 34 and the fixed wheel 4 are rotatably provided with casing, a tension measuring instrument 5 is fixedly installed on the outside of the top seat 3, wherein the tension measuring instrument 5 is a conventional standard part, which can be installed on the casing line path, and the tension measuring instrument 5 is used for real-time monitoring of casing line tension; and an adjusting mechanism 6 fixed on the base 1, the adjusting mechanism 6 is used for real-time adjustment of tension; and a shock absorbing assembly 7 fixed on the base 1, the shock absorbing assembly 7 is used for shock absorbing the adjusting mechanism 6, and the shock absorbing assembly 7 comprises a shock absorbing bottom plate 29, which is used for shock absorbing the bottom plate 29. The shock-absorbing bottom plate 29 is fixedly installed on the top of the base 1. The top of the shock-absorbing bottom plate 29 is symmetrically fixedly connected with a shock-absorbing block 30. The tops of multiple shock-absorbing blocks 30 are fixedly connected with shock-absorbing springs 31. The shock-absorbing principle of the shock-absorbing spring 31 is to absorb and relieve vibration by utilizing the elasticity of the spring. The interiors of multiple shock-absorbing springs 31 are fixedly connected with hydraulic rods 32. The hydraulic rods 32 can prevent the shock-absorbing springs 31 from rebounding quickly, thereby assisting the shock-absorbing springs 31 in shock-absorbing the adjustment mechanism 6. The ends of multiple shock-absorbing springs 31 away from the shock-absorbing blocks 30 are fixedly connected with shock-absorbing top plates 33. The shock-absorbing assembly 7 can absorb vibration energy, reduce the impact force on key components of the equipment, extend the service life of the equipment, reduce maintenance costs, ensure stable and reliable operation of the equipment, and at the same time facilitate improving the stability of tension adjustment, which helps to improve the tension adjustment effect.

[0032] For further information, see Figure 3 The adjusting mechanism 6 includes a motor 8, which is a servo motor. The motor 8 is fixedly mounted on the top of the shock-absorbing top plate 33. The output end of the motor 8 is fixedly connected to a planetary reducer 9. Due to the meshing mode and structural characteristics of the planetary gears, it is relatively stable during operation, and the vibration and noise generated are relatively small, which is convenient for cooperating with the motor 8 to adjust the tension.

[0033] For further information, please refer to Figure 3 The top of the base 1 is symmetrically fixedly connected with a bearing seat 10, and a limit frame 35 is fixedly connected between the two bearing seats 10. The output end of the planetary reducer 9 passes through the limit frame 35 and is fixedly connected with a screw 11. The screw 11 is a transmission screw, and the other end of the screw 11 is rotatably connected to the inside of the limit frame 35. The external thread of the screw 11 is connected to a screw nut seat 12. Due to the matching relationship between the screw 11 and the screw nut seat 12, the movement process is relatively smooth, which is convenient for stable operation of the equipment. The screw nut seat 12 is slidably connected to the limit frame 35, and the limit frame 35 is used to limit the screw nut seat 12 to ensure its horizontal movement. The top of the screw nut seat 12 is fixedly connected with a counterweight block 13, and the outside of the counterweight block 13 is fixedly connected with a connecting column 14, and the outside of the connecting column 14 is rotatably connected with a rotating shaft 15.

[0034] Embodiment 2: Figure 5 and Figure 6 As shown, this is a further description of Example 1. In this embodiment, the bottom of the connecting column 14 is fixedly connected to a connecting rod 16, and the bottom of the connecting rod 16 is fixedly connected to a magnifying glass 17. The magnifying glass 17 moves with the counterweight 13, which is convenient for the user to observe the movement value of the counterweight 13, and also convenient for the system to automatically scan and sense the value. The inside of the magnifying glass 17 is fixedly connected to an indicator mark 18, which is convenient for the user to observe the value. The outside of the limit frame 35 is fixedly connected to a scale line 19, which is convenient for observing the value on the scale line 19 through the magnifying glass 17 and the indicator mark 18, and convenient for the user to record the change of tension value. The outside of the rotating shaft 15 is fixedly connected to a tension wheel 36, which is used to assist in adjusting the tension. The outside of the rotating shaft 15 is symmetrically rotatably connected to a connecting seat 20.

[0035] Specifically, one of the connecting seats 20 is fixedly connected to a fixed plate 21 on the outside, and a limiting cylinder 22 is fixedly connected to the outside of the limiting cylinder 22. A movable rod 23 is slidably connected to the inside of the limiting cylinder 22. One end of the movable rod 23 is fixedly connected to a rotating cap 24. The other end of the movable rod 23 passes through the fixed plate 21 and is fixedly connected to a movable arc block 25. The movable rod 23 is threadedly connected to the fixed plate 21, and a protrusion 26 is fixedly connected to the outside of the movable arc block 25. The top of the other connecting seat 20 is fixedly connected to a fixed arc block 27. A slot 28 is provided inside the fixed arc block 27, and the slot 28 corresponds to the protrusion 26. By rotating the rotating cap 24, the rotating cap 24 drives the movable rod 23 to move, thereby driving the movable arc block 25 to approach the fixed arc block 27, and the protrusion 26 is stuck into the slot 28, forming an arc on the outside of the casing line. The protective ring prevents the sleeve from slipping when the adjustment mechanism 6 adjusts the tension, so as to assist the adjustment mechanism 6 in adjusting the sleeve tension. In a static state, the corresponding relationship between the displacement value of the counterweight block 13 and the tension change value is measured, and this corresponding relationship is stored in the system parameter formula. In production, the real-time tension is measured by the tension measuring instrument 5, and the difference between the measured value and the set value is compared. The system automatically calculates the required displacement value, and then the motor 8 and the lead screw 11 drive the counterweight block 13 to move the corresponding distance, so as to adjust the sleeve pay-off tension in real time. Real-time tension adjustment can keep the sleeve pay-off tension stable, thereby more accurately controlling the excess length of the optical fiber, avoiding excessive or too small excess length, ensuring the stable performance of the optical cable under different environments, and reducing the product failure rate caused by the excess length problem, thereby reducing the waste of raw materials and reducing production costs.

[0036] In summary, when using this device:

[0037] First, install the tension measuring instrument 5 on the casing wire path, measure the corresponding relationship between the displacement value of the counterweight block 13 and the tension change value in a static state, and store this corresponding relationship in the system parameter formula;

[0038] Next, the rotating cap 24 is rotated, and the rotating cap 24 drives the movable rod 23 to move, thereby driving the movable arc block 25 to approach the fixed arc block 27, and the protrusion 26 is inserted into the slot 28 to form an arc-shaped protective ring outside the casing line;

[0039] Finally, the tension of the casing line is measured in real time by the tension measuring instrument 5, and the difference between the measured value and the set value is compared, and the system automatically calculates the required displacement value.

[0040] Then the motor 8 and the planetary reducer 9 cooperate with each other to drive the lead screw 11 to rotate, thereby driving the lead screw nut seat 12 and the counterweight block 13 to move, and then driving the casing line to move a corresponding distance through the tension wheel 36, so that the casing pay-off tension can be adjusted in real time.
