A detachable crossbeam 110 is provided on the front or rear side of the hoisting frame 100. The crossbeam 110 can be removed to facilitate the disassembly and assembly of the reel frame 200. The cable can be firstly wound on the reel frame 200, and then the reel frame 200 can be installed on the hoisting frame 100, and finally the crossbeam 110 can be installed, so that the entire hoisting frame 100, the reel frame 200 and the connected cable can be moved to the front end of the pipe rack by hoisting. At the same time, the reel frame 200 can be driven to rotate by the driving device 300, so as to reduce the friction force when the cable is released, thereby reducing the difficulty of the release operation and improving the safety during the release construction process. The ICCP cable release tool of the embodiment of the utility model can complete the cable release work of the ICCP system by only one or two operators.

[0024] Reference Figure 1 and Figure 2 In this embodiment, the reel frame 200 is welded by steel pipe or square steel, and is composed of a plurality of circular frames 220, which are arranged at equal intervals along the rotating shaft 210, and the rotating shaft 210 passes through the center of each circular frame 220. A plurality of central support beams 230 are connected between the circular frame 220 and the rotating shaft 210, and the central support beams 230 are coplanar with the connected circular frame 220, and the central support beams 230 are radially distributed in the circular frame 220 at equal intervals. A plurality of peripheral surface support beams 240 are arranged at equal intervals on the circumference of the reel frame 200, and the peripheral surface support beams 240 are parallel to the direction of the rotating shaft 210. One end of the central support beam 230 on each circular frame 220 that faces away from the rotating shaft 210 is connected to the corresponding peripheral surface support beam 240, that is, part of the peripheral surface support beam 240 passes through the connection node between the corresponding central support beam 230 on each circular frame 220 and the circular frame 220. In this embodiment, the reel frame 200 includes four circular ring frames 220 and 16 peripheral surface support beams 240, and each circular ring frame 220 is provided with 8 central support beams 230, and the 8 central support beams 230 are connected to the corresponding peripheral surface support beams 240 at odd positions. Among them, 4 cross-ring support beams 250 are also arranged at equal intervals between the circular ring frames 220 at the left and right ends and the rotating shaft 210, and the first end of the cross-ring support beam 250 is connected to the circular ring frame 220, and the second end is connected to the rotating shaft 210, and the connection node with the rotating shaft 210 is located at the center of the adjacent circular ring frame 220. Taking the circular ring frame 220 at the left end as an example, the first end of the cross-ring support beam 250 is connected to the circular ring frame 220 at the left end, and the second end is connected to the rotating shaft 210 at the center of the second circular ring frame 220 from the left. The first end of the cross-ring support beam 250 is also connected to the corresponding central support beam 230. When the cable is wound on the reel frame 200, the weight of the cable is supported by the circumferential support beam 240, and the pressure on each point on the circumferential support beam 240 is dispersed through the central support beam 230, the cross-ring support beam 250 and the annular frame 220, so as to avoid stress concentration on the circumferential support beam 240 and deformation, thereby improving the strength of the entire reel frame 200. It is understandable that the circumferential support beam 240 can be composed of a single steel pipe or welded from multiple steel pipes.

[0025] In order to prevent the cable from being detached from the reel frame 200 at both ends when the cable is wound on the reel frame 200, refer to Figure 1 and Figure 2A plurality of side guard beams 260 are also provided on the circular frames 220 at the left and right ends.

It is understandable that the rotating shaft 210 and the hole on the hanging frame 100 for installing the rotating shaft 210 should be kept bright to further reduce the friction during the line release, and a sufficient amount of lubricating oil or grease should be poured between the rotating shaft 210 and the hole.

[0027] Reference Figure 1 and Figure 2 In this embodiment, the driving device 300 includes a driving bracket 320 and a reduction motor 310. The output shaft of the reduction motor 310 is connected to the shaft 210 of the reel frame 200. The reduction motor 310 is arranged on the driving bracket 320.
