Background Art

[0002] Coiled tubing is increasingly being used, particularly multi-channel, multi-functional coiled tubing containing fiber optic cables. These tubing plays a crucial role in numerous fields, including drilling, well engineering, road and bridge construction, marine, aerospace, polar regions, and urban underground construction and rescue. Currently, established coiled tubing storage equipment primarily consists of winches or hoists. While load-bearing continuous steel rope winches are convenient and fast to use, multi-channel, multi-functional coiled tubing winches with electrical cables present numerous operational challenges and fail to meet these requirements. Consequently, large-capacity coiled tubing storage and transportation devices have been developed. However, the large storage space required for long coiled tubing and the need to secure one end of the tubing are essential components of large-capacity coiled tubing storage and transportation devices. Therefore, the development of a sleeve-type, large-capacity coiled tubing storage and transportation system is crucial. Summary of the Invention

DETAILED DESCRIPTION

[0013] Referring to the accompanying drawings, the sleeve-type large-capacity coiled tubing storage system of the large-capacity coiled tubing storage and transportation device includes an outer guide rail 801 of an electric traction trolley, radial reinforcing ribs 802, circumferential reinforcing ribs 803, a tubing storage tube, a transition tube, a coiled tubing fixing mechanism 809, a radial reinforcing rib fixing plate 8010, a guide rail fixing member 8011, a trolley running chain 8012, and an inner guide rail 8013 of the electric traction trolley. The system is used to secure the stationary end of the coiled tubing 9 and to store the coiled tubing 9.

[0014] A plurality of radial reinforcing ribs 802 are fixedly connected to the interface of the sleeve-type large-capacity storage tube mechanism 3 through the radial reinforcing rib fixing plate 8010. The number of radial reinforcing ribs 802 is at least 3. The outer guide rail 801 of the traction electric control trolley and the inner guide rail 8013 of the traction electric control trolley are two concentric circular rings. The outer guide rail 801 of the traction electric control trolley and the inner guide rail 8013 of the traction electric control trolley are fixedly connected to the radial reinforcing rib 802 through the guide rail fixing piece 8011. The outer guide rail 801 of the traction electric control trolley and the inner guide rail 8013 of the traction electric control trolley provide a track for the traction electric control trolley 7. A reinforcing rib 803 is provided between two adjacent radial reinforcing ribs 802. At least N (≥2) groups of storage tubes are annularly distributed on the radial reinforcing ribs 802. The first to N-1 groups of storage tubes are each provided with a storage tube continuous tube outlet. The first group of storage tubes in the innermost circle is also provided with a storage tube continuous tube inlet. A transition tube is provided between two adjacent groups of storage tubes, each having a transition tube continuous tube outlet. A continuous tube fixing mechanism 809 for fixing the continuous tube inlet section is provided at the tail end of the storage tube continuous tube inlet (the direction from the beginning to the end is the direction of continuous tube storage).

[0015] Here, N is equal to 3, i.e., 3 groups of storage tubes and 2 groups of transition tubes are used as an example. Then, the storage tubes are the storage tube inner tube 804, the storage tube second tube 806, and the storage tube third tube 808, and the transition tubes are the transition tube inner tube 805 and the transition tube second tube 807.

[0016] The storage pipe inner tube 804, transition inner tube 805, storage pipe second tube 806, transition second tube 807 and storage pipe third tube 808 are concentrically distributed along the radial direction of the radial reinforcement rib 802. The storage pipe inner tube 804 is provided with an inner tube continuous tube outlet 80401 and an inner tube continuous tube inlet 80402. The transition inner tube 805 is provided with a transition inner tube continuous tube outlet 80501. The storage pipe second tube 806 is provided with a storage pipe second tube continuous tube outlet 80601. The transition second tube 807 is provided with a transition second tube continuous tube outlet. The inner tube continuous tube inlet 80402 is the position where the connecting pipe 9 enters from the ground and is relative to the ground. The stationary continuous pipe section is provided with a continuous pipe fixing mechanism 809 at the tail end of the inner tube continuous pipe inlet 80402 (the direction from the beginning to the end is the direction of continuous pipe storage). After the moving end of the connecting pipe is stored in the storage tube inner tube 804 for one circle, it will accumulate directly above the continuous pipe fixing mechanism 809. In this way, the moving end of the continuous pipe will spirally rise layer by layer in the storage tube inner tube 804 until the accumulated height reaches the same height as the inner tube continuous pipe outlet 80401. Then, the moving end of the connecting pipe will naturally exit the inner tube continuous pipe outlet 80401 and enter the transition inner tube 805 from the upper edge of the transition inner tube 805. As it continues to enter, After entering the transition inner tube 805 for half a circle to three quarters of a circle, the moving end of the continuous tube will gradually contact the bottom surface of the transition inner tube 805, and then the moving end of the continuous tube will reach the transition inner tube continuous tube outlet 80501 in the transition inner tube 805. The bottom end of the transition inner tube continuous tube outlet 80501 is at the same height as the bottom surface of the transition inner tube 805. The moving end of the continuous tube will naturally enter the bottom surface of the second storage tube 806 from the transition inner tube continuous tube outlet 80501 to start the first layer of storage. The moving end of the connecting tube will coil and spirally rise layer by layer in the second storage tube 806 until the cumulative height is at the same height as the continuous tube outlet 80601 of the second storage tube. The tube will exit the coiled tube outlet 80601 of the second storage tube and naturally enter the second transition tube 807, entering from the upper edge of the second transition tube 807. As it continues to enter, after entering the second transition tube 807 for half to three-quarters of a circle, the moving end of the coiled tube will gradually contact the bottom surface of the second transition tube 807. Then, the moving end of the coiled tube will reach the coiled tube outlet of the second transition tube in the second transition tube 807. The bottom end of the coiled tube outlet of the second transition tube is at the same height as the bottom surface of the second transition tube 807. The moving end of the coiled tube will naturally enter the bottom surface of the third storage tube 808 from the coiled tube outlet of the second transition tube, starting the first layer of storage and achieving layer-by-layer spiral ascent.

[0017] The coiled tubing fixing mechanism 809 includes a pin 80901, a base 80902, a pin shaft 80903, a coiled tubing lower clamping block 80904, and a coiled tubing upper clamping block 80905. The base 80902 is fixed to the radial reinforcing rib 802. The pin shaft 80903 is limited and rotated inside the base 80902 by the pin 80901. The upper end of the pin shaft 80903 is hinged to the coiled tubing lower clamping block 80904. The upper end of the coiled tubing lower clamping block 80904 is connected to a connecting member capable of clamping the fixed end of the coiled tubing via a bolt. The coiled tubing upper clamping block 80905 and the trolley running chain 8012 are fixedly connected to the outer side of the guide rail 8013 within the traction electric trolley to form a closed loop. The trolley running sprocket 707 is meshed with the trolley running chain 8012. The coiled tubing lower clamping block 80904 and the coiled tubing upper clamping block 80905 can clamp the fixed end of the coiled tubing and rotate horizontally and at a certain angle relative to the horizontal plane. The pin 80901 prevents the pin shaft 80903 from being pulled out of the coiled tubing lower clamping block 80904.

[0018] The working principle and use process of the present invention:

[0019] When removing the coiled tubing 9 from the present invention, the free end of the coiled tubing 9 inside the outermost ring storage tube is first passed through the storage and guiding mechanism 5. After being clamped by the storage and guiding mechanism 5, it is manually guided into the gooseneck reversing mechanism 1. After being changed in direction by the gooseneck reversing mechanism 1, it extends into the storage and injection mechanism 2, and finally the free end of the coiled tubing 9 is delivered to the destination below the ground.
