Description

Technical Field

[0001] The present invention relates to the technical field of cable retracting and releasing devices, and in particular to a cable retracting and releasing device for an automated marine geophysical exploration vessel. Background Art

[0002] Marine geophysical prospecting vessels are mainly used for marine geophysical exploration. With the development of science and technology, marine geophysical prospecting has developed rapidly in the modern oil industry. Marine geophysical prospecting vessels occupy an important position in the marine oil industry. At present, data packets are set at certain intervals in some marine cables. When the cable is recovered, the cable section with the data packet cannot be wound together, otherwise it may cause the cable section with the data packet to deform too much and cause damage to the data packet. Therefore, traditional marine geophysical prospecting vessels usually have to manually place the cable when retracting and releasing it, which is time-consuming and laborious.

[0003] At present, a Chinese invention with the announcement number CN201298719Y discloses a cable retracting and releasing device for a marine geophysical exploration vessel, including a fixing plate, a guide wheel, a cable recovery winch, a slide, a vertical guide wheel, a cable trough, a cable arrangement device, and a cable releasing winch, so that the data packet segment cable is not damaged when passing through the tension wheel and the cable is always kept compressed by a group of tension wheels to provide sufficient drag force to recover the cable. At the same time, a vertical guide wheel is arranged between the slide and the cable arrangement device to change the transmission direction of the cable, so that the cable is arranged in a serpentine shape in the cable laying trough to avoid damage to the data packet segment cable; however, on the one hand, the serpentine arrangement of the cable in the cable laying trough will take up a lot of space, reducing the number of cable retracting and releasing devices on the marine geophysical exploration vessel; on the other hand, when the specifications of the cable change and the spacing between adjacent data packet segment cables on the cable changes, the existing technology is cumbersome to adjust and it is difficult to ensure that the data packet segment cable is not damaged, and there is a need for improvement.

[0009] The present invention is further configured such that: the width of the adjustment shaft is provided with different specifications, and the adjustment shaft between adjacent base shafts is adjusted based on the diameter of the cable so that the width of the winding shaft is an integral multiple of the cable diameter.

[0010] The present invention is further configured as follows: the rotating abutment assembly includes an abutment seat that is locked and fixedly connected to the tensioning seat and a rotating hole that is coaxial with the rotating positioning axis and is provided on the tensioning seat; a rotating block is rotatably connected in the rotating hole; the rotating block is also provided with the positioning groove that cooperates with the positioning block; a plurality of first bolt holes are provided on the tensioning seat; a plurality of second bolt holes that cooperate with the first bolt holes are evenly and parallelly provided on the tensioning seat along the axial centerline direction of the rotating positioning axis; the abutment seat is adjustable and fixed on the tensioning seat based on bolts.

[0015] In summary, the present invention has the following beneficial effects:

[0016] 1. The cable reel includes a winding shaft coaxially arranged on a rotating positioning shaft and winding cones symmetrically arranged at both ends of the winding shaft. The winding cone is composed of a plurality of cone shafts, and the cross-sectional diameter of the winding cone at one end close to the winding shaft is equal to the diameter of the winding shaft, and the cross-sectional diameter of the winding cone gradually expands from the winding shaft to the outside. When the first circle of winding is performed, the conventional cable segment is wound on the winding shaft and continues to be wound on the winding cone until the data packet segment cable is wound on the outermost cone shaft at one end. By increasing the winding diameter of the data packet segment cable on the cable reel, the data packet segment cable is avoided. If the cable is damaged due to excessive deformation, the second winding direction is opposite to the first winding direction. At this time, the data packet segment cable is wound on the second-to-last cone shaft on the outermost side of the other end. Similarly, as the winding diameter increases and the distance between adjacent data packet segments is equal, the winding position of adjacent data packet segments on the cable reel will also move inward. This ensures that the winding diameter of the data packet segment cable on the cable reel is always balanced, avoiding damage to the data packet segment cable during the reeling and unreeling process, reducing the occupied space, and improving the reeling and unreeling efficiency.

[0017] 2. The winding shaft is composed of a group of symmetrically arranged base shafts and adjustment shafts locked and fixedly connected between the base shafts, and adjustment shafts of different width specifications are set. At the same time, the winding shaft is composed of several conical shaft components arranged in parallel. Since the cables have different specifications, the distances between adjacent data packet segment cables and the number of data packet segment cables on the cable are different. By adjusting the number and specifications of the adjustment shafts between the base shafts, the width of the winding shaft can be adjusted, thereby simplifying the operation while adapting to the requirements of retracting and releasing cables of different specifications, and reducing the adjustment cost.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example:

[0026] refer to Figures 1 to 5The cable guide 2 and the cable adjusting device 3 are respectively provided on the retracting and unwinding seat 1 along the cable conveying direction. The cable guide 2 guides the retracting and unwinding process of the cable and can also keep the cable taut during the retracting and unwinding process. The cable retracting roller 4 and the driving device 5 for driving the cable retracting and unwinding roller 4 to rotate at a certain speed are fixed at the end of the retracting and unwinding seat 1 along the cable conveying direction. The cable adjusting device 3 can adjust the conveying direction of the cable and thus adjust the position of the cable wound on the cable retracting and unwinding roller 4. The driving seat is fixed with a cable tensioning device 6 for ensuring that the cable is wound onto the cable retracting and unwinding roller 4 in a taut state.

[0027] refer to Figure 1 and Figure 2 Specifically, the cable tensioning device 6 includes a tensioning groove 61 provided on the retracting seat 1 and a tensioning seat 62 slidably connected to the tensioning groove 61 along the conveying direction of the cable. The cable retracting roller 4 and the driving device 5 are fixedly connected to the tensioning seat 62. A plurality of tensioning electric cylinders 63 for abutting the tensioning seat 62 are fixed in parallel in the tensioning groove 61. A pressure sensor 64 is fixed between the telescopic end of the tensioning electric cylinder 63 and the tensioning seat 62. As the cable wound on the cable retracting roller 4 is tightened, the tensioning A pulling force opposite to the direction of cable transmission causes the tensioning seat 62 to tend to slide in the direction of the pulling force. At this time, the pressure sensor 64 arranged between the telescopic end of the tensioning electric cylinder 63 and the tensioning seat 62 can measure the pressure of the tensioning seat 62 against the telescopic end of the tensioning electric cylinder 63, thereby indirectly reflecting the tension on the cable. If the tension is less than the standard, it means that the cable is in a relaxed state. The telescopic end of the telescopic electric cylinder extends out to abut the tensioning seat 62, so that the cable can always be in a tightened state.

[0028] refer to Figure 1 and Figure 2Specifically, the cable reel 4 includes a rotating positioning shaft 41 and a coaxially positioned and fixedly connected to the rotating positioning shaft 41 for winding conventional cable segments, and a coaxially symmetrically fixedly connected to both ends of the winding shaft 42 for winding data packet segment cables. At least two groups of positioning blocks 44 are evenly arranged on the rotating positioning shaft 41 along the circumferential direction, preferably four groups. Positioning grooves 45 that cooperate with the positioning blocks 44 are opened on the winding shaft 42 and the winding cone 43. The gap between the positioning blocks 44 and the positioning grooves 45 is The cooperation can ensure the stability of the connection while facilitating installation. The cross-sectional diameter of the winding cone 43 close to the winding shaft 42 is equal to the diameter of the winding shaft 42, and the cross-sectional diameter of the winding cone 43 gradually expands outward from the winding shaft 42. The outermost diameter of the winding cone 43 is not less than 1.8 times the diameter of the winding shaft 42. Rotating abutment components 46 for abutting the winding cone 43 against the two ends of the winding shaft 42 are provided at both ends of the rotating positioning shaft 41. The rotating abutment components 46 can make the winding shaft 42 and the winding cone 43 tightly fit together.

[0029] refer to Figure 1 、 Figure 2 and Figure 5Specifically, the winding shaft 42 includes a group of symmetrically arranged base shafts 421 and an adjustment shaft 422 locked and fixedly connected between the base shafts 421. The distance between adjacent data segment cables of different specifications is adjusted. The winding cone 43 includes a plurality of parallel tapered shafts 431. The distance is adjusted based on the number of data segment cables on the cable. The adjacent base shafts 421, the adjustment shafts 422 and the tapered shafts 431 are fixedly connected by bolts. When performing the first round of winding, the conventional segment cable is wound on the winding shaft 42 and continues to be wound on the winding cone 43 until the data segment cable is wound on the outermost tapered shaft 43 at one end. 1, by increasing the winding diameter of the data packet segment cable on the cable retracting roller 4, the data packet segment cable is prevented from being damaged due to excessive deformation. When the second circle is wound, the winding direction is opposite to the first circle. At this time, the data packet segment cable is wound on the second-to-last tapered shaft 431 on the outermost side of the other end. Similarly, as the winding diameter increases and the distances between adjacent data packet segment cables are equal, the winding positions of adjacent data packet segment cables on the cable retracting roller 4 will also move inward, which ensures that the winding diameters of the data packet segment cables on the cable retracting roller 4 always remain balanced, thereby preventing the data packet segment cables from being damaged during the winding and unwinding process. The width of the adjustment shaft 422 is set in different specifications. The adjustment shaft 422 between adjacent base shafts 421 is adjusted based on the diameter of the cable so that the width of the winding shaft 42 is an integer multiple of the cable diameter. Since the cables have different specifications, the distance between adjacent data packet segment cables and the number of data packet segment cables on the cable are different. By adjusting the number and specifications of the adjustment shafts 422 between the base shafts 421, the width of the winding shaft 42 can be adjusted, thereby simplifying the operation while adapting to the requirements of retracting and releasing cables of different specifications, while reducing the adjustment cost.

[0030] refer to Figure 1 and Figure 2Specifically, the rotating abutment assembly 46 includes an abutment seat 461 that is locked and fixedly connected to the tightening seat 62 and a rotating hole 462 that is coaxial with the rotating positioning shaft 41 and is provided on the tightening seat 62. A rotating block 463 is coaxially connected to the rotating hole 462, and a positioning groove 45 that cooperates with the positioning block 44 is also provided on the rotating block 463. The rotating positioning shaft 41 is fixedly connected in the rotating block 463 and rotates with the rotating block 463. A plurality of first bolt holes 464 are provided on the tightening seat 62, and a plurality of first bolt holes 464 are evenly arranged in parallel on the tightening seat 62 along the axis of the rotating positioning shaft 41. The abutment seat 461 is fixedly secured to the tensioning seat 62 via a second bolt hole 465 that mates with the first bolt hole 464. The position of the abutment seat 461 on the tensioning seat 62 can be easily adjusted by mate-ing the first bolt hole 464 with a different second bolt hole 465, thereby adapting to the width adjustment of the winding shaft 42. This is simple and inexpensive to adjust. Furthermore, to ensure a smooth winding process and prevent damage to the cable due to excessive bending during transport, the cable adjustment device 3 is always positioned within the center plane of the winding shaft 42 during the width adjustment of the winding shaft 42. The drive device 5 includes a drive seat fixedly connected to the abutment seat 461 and a drive motor 52 fixedly connected to the drive seat. The cable retraction and retraction function is achieved by controlling the rotational direction of the drive motor 52. A speed reducer 53 is connected between the output end of the drive motor 52 and the rotary positioning shaft 41. The speed reducer 53 reduces the rotational speed of the cable retraction roller 4 and increases the torque exerted on the cable retraction roller 4 by the drive motor 52.

[0031] refer to Figure 1 and Figure 4 Specifically, the cable adjustment device 3 includes a screw adjustment assembly 31 fixedly connected to the retracting and unloading seat 1 along the axial direction parallel to the rotation positioning axis 41, and a sliding seat 32 slidably connected to the screw adjustment assembly 31. A group of adjustment rollers 33 are symmetrically and slidably connected to the sliding seat 32 along the sliding direction. The cross-section of the adjustment roller 33 is an arc-shaped structure. The cable passes between the two adjustment rollers 33, and the cable conveying direction is adjusted by the position of the adjustment seat 35 on the screw adjustment assembly 31. A spacing adjustment assembly 34 for adjusting the distance between the adjustment rollers 33 is fixed on the sliding seat 32. The spacing adjustment assembly 34 includes an adjustment seat 35 fixedly connected to the sliding seat 32, and a group of adjustment screws 36 that are interconnected, coaxially arranged and rotate in opposite directions are rotatably connected to the adjustment seat 35. An adjustment motor 37 is fixedly provided on the adjustment seat 35 to drive the adjustment screw 36 to rotate, and an adjustment block 38 that is slidably connected to the adjustment screw 36 is fixedly connected to the adjustment roller 33. When the diameter of the cable changes, the adjustment motor 37 drives the adjustment screw 36 to rotate, so that the two adjustment blocks 38 move in opposite directions, thereby realizing synchronous adjustment of the spacing between the two adjustment rollers 33.

[0032] refer to Figure 1 and Figure 3 Specifically, the cable guiding device 2 includes a first guide seat 21 fixedly connected to the retracting seat 1 and a second guide seat 22 slidably connected to the first guide seat 21 along the vertical direction. Several groups of guide wheels 23 are rotatably connected to the first guide seat 21 and the second guide seat 22 along the cable conveying direction. An adjusting electric cylinder 25 is fixedly connected to the first guide seat 21 along the vertical direction to drive the second guide seat 22 to slide up and down. The adjusting electric cylinder 25 adapts to the guiding requirements of cables of different diameters by adjusting the gap between the guide wheels 23 on the first guide seat 21 and the second guide seat 22. It has a simple structure and is easy to adjust.

[0033] A brief description of the usage process: the cable passes through the guide groove 11 and enters the cable guide device 2 for guidance. After passing through the cable guide device 2, the cable enters the cable adjustment device 3 and is connected to the cable take-up roller 4. The driving device 5 drives the cable take-up roller 4 to rotate so that the cables are wound onto the cable take-up roller 4 in parallel. When performing the first circle of winding, the conventional cable segment is wound on the winding shaft 42 and continues to be wound on the winding cone 43 until the data packet segment cable is wound on the outermost cone shaft 431 at one end. When performing the second circle of winding, the direction is opposite to the first circle of winding. At this time, the data packet segment cable is wound on the outermost second-to-last cone shaft 431 at the other end, and so on. As the winding direction increases, the cable is wound onto the outermost second-to-last cone shaft 431 at the other end. The increase in diameter and the distance between adjacent data packet segment cables are equal, and the winding position of adjacent data packet segment cables on the cable reel 4 will also move inward, which ensures that the winding diameter of the data packet segment cable on the cable reel 4 always remains balanced. When the specifications of the cable change, resulting in the distance between adjacent data packet segment cables and the number of data packet segment cables on the cable are different, the width of the winding shaft 42 can be adjusted by adjusting the number and specifications of the adjustment shafts 422 between the base shafts 421, and the position of the abutment seat 461 can be adjusted to adapt to the reeling and winding requirements of cables of different specifications. When the cable needs to be released, the drive motor 52 is reversed to achieve cable release.

[0034] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make creative modifications to this embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
