[0002] Cable is a general term for items such as optical cables and electrical cables. Cables have many uses, primarily controlling installations, connecting devices, and transmitting power. They are a common and indispensable part of everyday life. To enhance the aesthetics and cleanliness of urban environments, cables are often placed underground, creating underground cables for power and communications transmission.

[0003] When using downhole cables, they need to be inspected or replaced at regular intervals to ensure normal power or communication. When replacing downhole cables, a retractable device is required for cable retraction and release. When releasing cables, common downhole cable retractable devices generally use manpower to continuously pull out cables from the device. The pulled-out cables replace the original cables and enter the well. However, the cables in the well are arranged relatively tightly, and the newly entered cables will produce greater friction with the remaining cables in the well, making the cable replacement process very laborious. This not only increases the labor intensity of the workers, but also easily damages the cables due to strong pulling, which is not conducive to cable replacement and use. Utility Model Content

[0025] The position adjustment assembly includes a carrier plate 18, which is fixedly mounted on the oil storage tank 2. A first bolt 19 is threadedly connected to the top of the carrier plate 18. The bottom end of the first bolt 19 is rotatably connected to a second U-shaped plate 20 via a bearing. Both ends of the pressure roller 15 are rotatably connected to the second U-shaped plate 20 via bearings. A guide rod 21 is fixed to the top of the second U-shaped plate 20. A through hole is opened on the top of the carrier plate 18 for the guide rod 21 to slide.

[0026] The drive motor 5 is used to drive the take-up and release disk 7 to rotate in the opposite direction, so as to release the cable wound on the take-up and release disk 7. The drive motor 5 uses the linkage assembly to pull the transmission roller 11 to rotate, so that the transmission roller 11 cooperates with the auxiliary roller 12 to prevent the cable wound on the take-up and release disk 7 from loosening while releasing the cable. When the cable is released, the first bolt 19 can be tightened with the help of a wrench to push the pressure roller 15 downward, squeezing the cable between the oil storage tank 2 and the pressure roller 15 into the oil storage tank 2, so that the cable can be lubricated before the downhole cable replacement operation is carried out.

[0027] Among them, the linkage assembly includes a first sprocket 22 and a second sprocket 23.

[0030] Working principle of this utility model:

[0031] The device is moved to a designated position with the aid of the four universal casters 17. The universal casters 17 are locked by the self-locking structure thereof, so that the universal casters 17 cannot move further. The identification plates 27 are pulled outward to increase the distance between the two identification plates 27 until the adjustment plate 26 cannot be further withdrawn from the storage slot. The second bolt 28 can then be tightened with a wrench to lock the T-shaped plate 25 and the adjustment plate 26. This completes the stabilization of the three shapes of the T-shaped plate 25, the adjustment plate 26, and the identification plate 27. The three form a barrier to warn pedestrians not to approach.

[0032] When winding the cable, the worker pulls the old cable out of the well, starts the drive motor 5 to drive the take-up drum 7 to rotate forward, and the drive motor 5 drives the transmission roller 11 to rotate with the help of the linkage assembly. The worker passes the old cable between the transmission roller 11 and the auxiliary roller 12, and then pulls the old cable onto the take-up drum 7. The operation of the drive motor 5 is suspended until the worker inserts one end of the old cable into the cable insertion slot 16. Then the drive motor 5 is started again to drive the take-up drum 7 to reel in the old cable.

[0033] Paying out and taking up the line are generally performed simultaneously. When using this device to pay out the line, the drive motor 5 can be controlled to drive the take-up disc 7 to rotate in the opposite direction. At this time, a new cable has been pre-wound on the take-up disc 7. The new cable is passed through between the oil storage tank 2 and the pressure roller 15. The first bolt 19 is tightened with a wrench so that the new cable is squeezed into the inside of the oil storage tank 2 and adheres to the lubricating oil stored in the oil storage tank 2. The worker pulls the new cable into the well and uses tools to fix the ends of the new and old cables. As the old cable is pulled out, the new cable adhered to the lubricating oil is replaced in the well.
