[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-3 As shown, a fiber optic cable erection end traction device includes a movable base 1, with movable frames 2 slidably installed on both sides inside the movable base 1, and traction belts 3 rotatably installed on the inner sides of the two movable frames 2 via rotating rollers.

[0023] A traction motor 4 is installed at the front of the top of the movable frame 2, and the shaft of the traction motor 4 is connected to the roller of the traction belt 3. An optical cable body 5 is provided on the inner side of the traction belt 3. Two support rods 6 are fixedly connected at the rear of the top of the movable base 1, and the positions of the support rods 6 match those of the movable frame 2. A conical rotating cylinder 7 is slidably connected to the outer ring of the support rod 6. A second conical rotating cylinder is slidably connected to the outer ring of the support rod 6 and located below the first conical rotating cylinder 7. The optical cable body 5 is located between the upper and lower ends of the second conical rotating cylinder and the first conical rotating cylinder 7. A fixing spring 8 is provided at the upper part of the outer ring of the support rod 6. The top of the fixing spring 8 is connected to the support rod 6, and the bottom of the fixing spring 8 abuts against the top of the first conical rotating cylinder 7.

[0024] In this embodiment, the outer rings of the two support rods 6 are provided with external threads, and two adjusting nuts are connected by the external threads. The upper and lower ends of the adjusting nuts abut against the upper and lower ends of the conical rotating cylinder 2, respectively. By turning the adjusting nuts at the conical rotating cylinder 2, the support height of the conical rotating cylinder 2 can be adjusted, which makes it easier to lift the optical cable body 5 to a suitable height, reduce the downward pulling force of the optical cable body 5, and improve the smoothness of traction.

[0025] In this embodiment, a fixed plate is fixedly connected to the center of the bottom of the movable frame 2. Adjusting screws 9 are threaded through both sides of the fixed plate and are rotatably installed inside the movable base 1. By rotating the adjusting screws 9, the movable frame 2 is driven to slide on the movable base 1, which facilitates the adjustment of the distance between the two traction belts 3 and the adjustment of the clamping force. The fact that the adjusting screws 9 are rotatably installed inside the movable base 1 avoids interference from the movable base 1 to the rotation of the adjusting screws 9.

[0026] In this embodiment, a fixed tube 10 is fixedly installed at the front of the top of the movable base 1, and a guide tube 11 is rotatably installed at the front end of the fixed tube 10. Both the top and front ends of the guide tube 11 are provided with outlets. Several balls are provided inside the fixed tube 10 and the guide tube 11. The end of the optical cable body 5 away from the traction belt 3 passes through the fixed tube 10 and the guide tube 11. The fixed tube 10 and the guide tube 11 facilitate the guidance of the optical cable body 5. The balls rotate with the traction of the optical cable body 5, which can reduce the probability of the optical cable body 5 getting stuck and reduce friction.

[0027] In this embodiment, a plug rod 12 is movably installed on the outer ring of the guide tube 11 near the upper and lower ends via an adjusting plate. A return spring 13 is provided around the outer ring of the plug rod 12. An annular insert plate is provided at the connection between the fixed tube 10 and the guide tube 11. Several insertion holes matching the plug rod 12 are provided at the front and rear ends of the annular insert plate. By pulling the plug rod 12 away from the fixed tube 10, the plug rod 12 is disengaged from the insertion hole, thereby releasing the fixation of the guide tube 11. Afterward, the guide tube 11 can be rotated to adjust the angle pulled out by the optical cable body 5.

[0028] In this embodiment, the front end of the reset spring 13 is connected to the front end of the insertion rod 12 through a connecting block, and the rear end of the reset spring 13 is connected to the adjustment plate. The front end of the connecting block is provided with a pull ring. After adjusting the guide tube 11, the reset spring force of the reset spring 13 will drive the insertion rod 12 to reset and be inserted into the insertion hole again, which is convenient for fixing and prevents the guide tube 11 from being rotated by external force. The pull ring also makes it easy for personnel to pull.

[0029] In this embodiment, a fixing frame 14 is provided at the front position of the outer ring of the optical cable body 5, and a handle is provided at the front end of the fixing frame 14. Clamping knobs 16 are threaded through both sides of the fixing frame 14. Clamping plates 15 are rotatably installed on the inner side of the two clamping knobs 16, and the inner side of the clamping plates 15 is in contact with the outer ring of the optical cable body 5. Anti-slip texture is provided at the contact point. By inserting the optical cable body 5 into the fixing frame 14 and placing it inside the two clamping plates 15, and then turning the clamping knobs 16, the two clamping plates 15 are brought closer to each other, which facilitates the fixing of the end of the optical cable body 5. At the same time, the handle is provided for easy gripping by personnel.

[0030] It should be noted that this utility model is a fiber optic cable laying end traction device. When in use, firstly, when the fiber optic cable body 5 is laid for a long length, a section of the fiber optic cable body 5 can be pulled out as needed, and the pulled-out fiber optic cable body 5 is passed between the conical rotating drum 1 7 and the conical rotating drum 2. Then it is passed through the inside of the two traction belts 3, and then the fiber optic cable body 5 is passed through the fixed tube 10.

[0031] Meanwhile, since the guide tube 11 has two outlets, the appropriate outlet can be selected to pass the optical cable body 5 through according to actual needs. Then the optical cable body 5 can be passed into the fixing frame 14 and placed inside the two clamps 15. Then the clamping knob 16 is turned to bring the two clamps 15 closer to each other and fix the end of the optical cable body 5.

[0032] After the fixed frame 14 is fixed, the personnel can hold the handle on the fixed frame 14 to pull out the optical cable body 5. During the pulling, the traction motor 4 can be started as needed. Since the traction belt 3 is installed on the movable frame 2 through the rotating roller, and the shaft of the traction motor 4 is connected to the rotating roller of the traction belt 3, the traction belt 3 can be rotated by the rotation of the shaft of the traction motor 4, so that the optical cable body 5 can be gradually pulled out of the optical cable drum. This plays a role in assisting the personnel to pull and reduce the labor intensity of the personnel. At the same time, the movable frame 2 is slidably installed on the movable base 1, and the movable frame 2 is threadedly connected to the adjusting screw 9. Thus, the movable frame 2 can be slid on the movable base 1 by rotating the adjusting screw 9. The two traction belts 3 can be adjusted to move away from or closer to each other, so as to adjust the clamping force.

[0033] Meanwhile, conical rotating drum 1 and conical rotating drum 2 are set at the inlet of the traction belt 3. The adjusting nut at conical rotating drum 2 can be turned alternately as needed to adjust the support height of conical rotating drum 2. The optical cable body 5 can be lifted to a suitable height as needed, which helps to reduce the downward pulling force of optical cable body 5, and at the same time reduces the probability of optical cable body 5 detaching from traction belt 3, and improves traction smoothness.

[0034] When it is necessary to adjust the traction angle of the optical cable body 5, the insertion rod 12 can be pulled out in the direction away from the fixed tube 10 as needed, thereby releasing the fixation of the guide tube 11. Since the guide tube 11 is rotatably installed on the fixed tube 10, the angle of the optical cable body 5 can be adjusted by rotating the guide tube 11. After adjusting to the appropriate angle, the insertion rod 12 can be released as needed. Through the reset spring force of the reset spring 13, the insertion rod 12 will be reset and inserted into the insertion hole again to complete the adjustment process. Before adjustment, it is necessary to ensure that the optical cable body 5 extends out from the upper outlet of the guide tube 11.

[0035] Furthermore, the guide tube 11 and the fixing tube 10 are equipped with several equidistantly arranged ball bearings. When the optical cable body 5 enters the guide tube 11 and the fixing tube 10, the ball bearings rotate with the traction of the optical cable body 5, which can reduce the probability of the optical cable body 5 getting stuck. At the same time, it can reduce the friction and reduce the probability of the outer sheath of the optical cable body 5 being scratched.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
