The connecting shaft rotates through the closed annular structure to drive the cable body clamped between the three closed annular structures to move forward, and the adaptive unit can automatically adjust to match the shape of the cable body.

[0011] Furthermore, the structures of all the adaptive units are equal. Taking any one of the adaptive units as an example, the adaptive unit includes N levels of crescent columns, N is a positive integer greater than 2, wherein there is one first-level crescent column, and the first-level crescent column is arranged in the arc groove of the turntable body; two arc grooves are provided on each of the crescent columns of each level, and for the i-th level crescent column, i is a positive integer less than N, and an i+1-th level crescent column is respectively arranged in each arc groove of each crescent column; each of the crescent columns is limited in the corresponding arc groove and can rotate on the arc surface of the corresponding arc groove; for any one of the turntables, the N-th level crescent columns on its two turntable bodies can form a closed annular structure.

[0012] Furthermore, six arc grooves are provided on the side wall of each of the turntable bodies. Taking any one of the adaptive units as an example, the adaptive unit includes four levels of crescent columns, wherein the first-level crescent column is arranged in the arc groove of the turntable body and can rotate on the arc surface of the arc groove, a second-level crescent column is respectively arranged in each arc groove of the first-level crescent column, a third-level crescent column is respectively arranged in each arc groove of each crescent column of the second level, and a fourth-level crescent column is respectively arranged in each arc groove of each crescent column of the third level.

DETAILED DESCRIPTION

[0032] In order to better understand the purpose, structure and function of the present invention, a cable guiding mechanism of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0033] like Figure 1-Figure 2 As shown, it shows a cable guiding mechanism of an embodiment of the present invention, including a three-jaw chuck 01, the chuck body of the three-jaw chuck 01 is fixed on a supporting mechanism 02, and the supporting mechanism 02 is used to support the three-jaw chuck 01; each jaw 012 of the three-jaw chuck 01 is respectively connected to an actuator, at least one actuator is connected to a driving mechanism, the driving mechanism is fixed on the jaw 012 of the three-jaw chuck 01 connected to the actuator, the driving mechanism is used to drive the actuator connected thereto to rotate, and the rotation of the actuator can drive the cable body clamped between the three actuators to move.

[0034] The cable guide mechanism of this embodiment is used to clamp the cable body of the marine seismic exploration streamer and the submarine cable, and to drive the cable body to move.

[0035] The cable guiding mechanism of this embodiment includes a supporting mechanism 02 and a three-jaw chuck 01. The supporting mechanism 02 can be set to a corresponding height according to actual working conditions, or the three-jaw chuck 01 can be directly fixed on the supporting structure at the required working environment.

[0036] Specifically, the cable guide mechanism includes a three-jaw chuck 01, and the three jaws 012 of the three-jaw chuck 01 can be moved closer to or farther away from each other by adjusting the square hole 011 of the bevel gear on the three-jaw chuck 01. Each jaw 012 of the three-jaw chuck 01 is connected to an actuator, and the cable body of the marine seismic exploration tow cable and the submarine cable is clamped between the three actuators. Therefore, by adjusting the square hole 011 of the bevel gear on the three-jaw chuck 01, the actuators can be moved closer to or farther away from each other, thereby clamping or releasing the clamped cable body.

[0037] At least one actuator is connected to a driving mechanism, and the driving mechanism is used to drive the corresponding actuator to rotate. The rotation of the actuator can drive the cable body clamped between the three actuators to move forward through the friction between the actuator and the cable body.

[0038] The cable guiding mechanism of the present embodiment can be applied to clamp cables of different radii, and has good versatility; the cable guiding mechanism of the present embodiment saves and liberates manpower, and can obtain greater traction force; the cable guiding mechanism of the present embodiment ensures the personal safety of the operator. Due to the influence of the flow direction of the seawater, non-directional force is often generated when the guiding cable is retracted and released, and manual cable holding may knock people away, while the cable guiding mechanism of the present embodiment overcomes the above-mentioned shortcomings; the setting of the three-jaw chuck 01 of the present embodiment can control the guided cable body to always remain at the center of the three-jaw chuck 01, thereby preventing the trajectory of the guided cable body from deviating; the present embodiment can control the direction of the cable guiding by adjusting the position of the actuator on the support mechanism 02, thereby overcoming the shortcomings of the prior art that the cable body itself is hard and it is difficult for manpower to change the direction; the cable guiding mechanism of the present embodiment has the advantage of strong mobility, and the three-jaw chuck 01 can be fixed on the support mechanism 02 at a position that meets the requirements as needed.

[0039] Among them, the structures of the three actuators are the same. Taking any one claw 012 of the three-jaw chuck 01 as an example, an extension plate 05 is fixed on both sides of the claw 012, and the actuator connected to the claw 012 includes a connecting shaft 04 and a turntable 06. Bearings 041 are respectively arranged between the connecting shaft 04 and the two extension plates 05. The turntable 06 is limited between the two extension plates 05. The turntable 06 is fixedly connected to the connecting shaft 04, and the cable body is clamped between the outer walls of the three turntables 06.

[0040] Specifically, each clamping jaw 012 corresponds to an actuator, and the actuator includes a connecting shaft 04. For any clamping jaw 012, extension plates 05 are fixedly connected on both sides along the circumferential direction of the chuck body, and the corresponding connecting shaft 04 passes through the extension plates 05 on both sides thereof. The setting of the extension plates 05 here serves the purpose of supporting the connecting shaft 04. In addition, bearings 041 are arranged between the corresponding connecting shaft 04 and each of the extension plates 05 on both sides thereof, wherein the inner ring of the bearing 041 is interference fit with the connecting shaft 04, and the outer ring of the bearing 041 is interference fit with the extension plate 05.

[0041] Again, the actuator also includes a turntable 06. For any claw 012, its corresponding turntable 06 is arranged between the extension plates 05 on both sides thereof, and its corresponding turntable 06 is fixedly arranged on its corresponding connecting shaft 04, for example, its corresponding turntable 06 is fixedly arranged on its corresponding connecting shaft 04 through a connecting key.

[0042] To reiterate: for any turntable 06, its surface is parallel to the movement direction of its corresponding claw 012. Therefore, when the three claws 012 of the three-jaw chuck 01 are brought closer to each other by adjusting the square hole 011 of the bevel gear on the three-jaw chuck 01, the three turntables 06 are brought closer to each other, thereby achieving the purpose of clamping the cable body between the outer walls of the three turntables 06. When the three claws 012 of the three-jaw chuck 01 are moved away from each other by adjusting the square hole 011 of the bevel gear on the three-jaw chuck 01, the cable body clamped between the three turntables 06 can be released.

[0043] Among them, the connecting shaft 04 corresponding to at least one claw 012 is connected to a driving mechanism, and the driving mechanism is fixed on one of the extension plates 05 of the claw 012. The driving mechanism is used to drive the connecting shaft 04 connected thereto to rotate. The rotation of the connecting shaft 04 drives the cable body clamped between the outer walls of the three turntables 06 to move forward through the turntable 06.

[0044] When the cable body is clamped between the three turntables 06, when there is only one driving mechanism, the driving mechanism is controlled to rotate to drive the turntable 06 to rotate through the connecting shaft 04. When there are more than one driving mechanism, each driving mechanism is controlled to rotate to make the turntable 06 rotate in the same direction. The rotation of the turntable 06 causes the cable body to move forward through the friction between the turntable 06 and the cable body.

[0045] For a cable body whose diameter does not change substantially, the turntable 06 of this embodiment is, for example, configured as a common round disc having a hanging point function.

[0046] Considering the redundant design, the present embodiment has three driving mechanisms, that is, each actuator is connected to a driving mechanism, and each driving mechanism is fixedly connected to a jaw 012 of the three-jaw chuck 01.

[0047] Under normal working conditions, one driving mechanism can drive the cable body to move forward through the turntable 06. This embodiment adopts a redundant design of three driving mechanisms to increase the reliability of the cable guiding mechanism.

[0048] The driving mechanism includes a driving motor 03 , which is fixed on a motor base 031 , and the motor base 031 is fixedly connected to one of the extension plates 05 of the corresponding claw 012 of the driving motor 03 ; the motor shaft of the driving motor 03 is connected to the connecting shaft 04 through a coupling 042 .

[0049] In the case of setting up three driving mechanisms, each claw 012 corresponds to a driving motor 03. For any claw 012, its corresponding driving motor 03 is fixed on one of the extension plates 05 on both sides thereof, and its corresponding driving motor 03 is connected to its corresponding connecting shaft 04 through a coupling 042.

[0050] Finally, when the cable body is clamped between the three turntables 06, the three drive motors 03 are controlled to rotate forward or reverse at the same time, and the motor shaft of the drive motor 03 drives the turntable 06 to rotate through the connecting shaft 04. The rotation of the turntable 06 causes the cable body to move forward through the friction between the turntable 06 and the cable body.

[0051] With respect to the three turntables 06, the structures of the three turntables 06 are the same. Taking any one turntable 06 as an example, the turntable 06 includes two turntable bodies 061 with equal diameters. The two turntable bodies 061 are fixed on the corresponding connecting shaft 04. A plurality of arc grooves 0611 are provided on the side wall of each turntable body 061. An adaptive unit is provided in each arc groove 061. The adaptive units on the two turntable bodies 061 of each turntable form a closed annular structure with a diameter greater than that of the turntable body 061. The connecting shaft 04 rotates through the closed annular structure to drive the cable body clamped between the three closed annular structures to move forward, and the adaptive unit can automatically adjust to match the shape of the cable body.

[0052] In this embodiment, each turntable includes two turntable bodies 061, and the diameters of the two turntable bodies 061 are equal. The two turntable bodies 061 are fixed to the corresponding connecting shaft 04 through a connecting key. For the two turntable bodies 061 on any connecting shaft 04, each turntable body 061 is provided with an arc groove 0611, and the number of arc grooves 061 on the two turntable bodies 061 is equal. The arc grooves 0611 on the two turntable bodies 061 are staggered. Since an adaptive unit is provided in each arc groove 0611, the adaptive units on the two turntable bodies 061 corresponding to any connecting shaft 04 are staggered, that is, each adaptive unit on one turntable body 061 is located between two adaptive units on the other turntable body 061.

[0053] Again, the adaptive units on the two turntable bodies 061 of each turntable form a closed annular structure with a diameter greater than the diameter of the turntable body 061, that is, the closed annular structure is located outside the turntable body 061, so in the process of clamping the cable body, the closed annular structure directly contacts the cable body. During the rotation of the driving motor 03, the driving motor 03 drives the connecting shaft 04 and the turntable body 061 to rotate, and the closed annular structure formed by the adaptive unit rotates accordingly. The rotation of the closed annular structure drives the cable body clamped between the three closed annular structures to move forward through friction. Since the adaptive units on the two turntable bodies 061 on the same connecting shaft 04 are staggered with each other, and the diameter of the closed annular structure is greater than the diameter of the turntable body 061, the two turntable bodies 061 are described as the A turntable body 061 and the B turntable body 061, respectively. In the process of the rotation of the closed annular structure, the adaptive structure on the A turntable body 061 drives the cable body to move forward, the adaptive structure on the B turntable body 061 drives the cable body to move forward, and the adaptive structure on the A turntable body 061 drives the cable body to move forward in a cycle.

[0054] Finally, the adaptive unit of this embodiment can automatically adjust to match the shape of the cable body, that is, after the adaptive unit clamps the cable body, when the diameter of the cable body changes, there is no need to adjust the three-jaw chuck 01 again, and the adaptive unit can adaptively adjust to clamp the cable body according to the diameter of the cable body. Therefore, the cable guide mechanism of this embodiment can adaptively guide the diameter of the cable body and has a clamping effect on irregular (non-circular cross-section) shaped cables.

[0055] Among them, the structures of all the adaptive units are equal. Taking any one of the adaptive units as an example, the adaptive unit includes N levels of crescent columns 062, N is a positive integer greater than 2, wherein there is one first-level crescent column 062, and the first-level crescent column 062 is arranged in the arc groove 0611 of the turntable body 061; two arc grooves 0611 are provided on each crescent column 062 of each level, and for the i-th level crescent column 062, i is a positive integer less than N, and each arc groove 0611 of each crescent column 062 is respectively provided with an i+1-th level crescent column 062; each crescent column 062 is limited in the corresponding arc groove 0611 and can rotate on the arc surface of the corresponding arc groove 0611; for any turntable, the N-th level crescent columns 062 on its two turntable bodies 061 can form a closed annular structure.

[0056] As can be seen from the above, the turntable body 061 is provided with a plurality of arc-shaped grooves 0611, and each arc-shaped groove 0611 is provided with an adaptive unit, wherein any adaptive unit is taken as an example to be described as follows:

[0057] The adaptive unit includes N levels of crescent columns 062, where N is a positive integer greater than 2, and each crescent column 062 of each level is provided with two arc grooves 0611. There is one first-level crescent column 062, which is arranged in an arc groove 0611 of the corresponding turntable body 061, and the first-level crescent column 062 is limited in the corresponding arc groove 0611 and can rotate on the arc surface of the corresponding arc groove 0611; the adaptive unit has two second-level crescent columns 062, which are respectively arranged in the two arc grooves 0611 of the first-level crescent column 062, and the two crescent columns 062 are limited in their respective arc grooves 0611 and can rotate on the arc surface of their respective arc grooves 0611. The two crescent columns 062 are each provided with two arc grooves 0611; similarly, for the case where N is greater than or equal to 3, the adaptive unit has four third-stage crescent columns 062, and these four crescent columns 062 are respectively provided in the four arc grooves 0611 of the two second-stage crescent columns 062, and these four crescent columns 062 are limited in their respective arc grooves 0611 and can rotate on the arc surfaces of their respective arc grooves 0611, and each of these four crescent columns 062 is provided with two arc grooves 0611.

[0058] Finally, regarding the crescent column 062 and the arc groove 0611 matched therewith, for example, the angle at which each crescent column 062 can rotate in the arc groove 0611 is 60 degrees. For the number N of crescent columns 062, it is also necessary to satisfy that the Nth-level crescent columns 062 of the two turntable bodies 061 on the same connecting shaft 04 can form a closed annular structure, that is, taking the example of M arc grooves 0611 on each turntable body 061, and correspondingly M adaptive units on each turntable body 061, then the Nth-level crescent columns 062 of the 2M adaptive units on the two turntable bodies 061 can surround a closed annular structure. For the case of a total of N levels of crescent columns 062, since there is no nesting of the N+1th-level crescent column 062 and the Nth-level crescent column 062, the arc groove 0611 may not be set on the Nth-level crescent column 062. Figure 6 shown.

[0059] When the cable body changes from a conventional circular cross section to another cross section, during the clamping process of the adaptive unit, each crescent column 062 will rotate on the arc surface of its corresponding arc groove 0611, thereby achieving the function of automatically clamping the special-shaped cross section.

[0060] In specific implementation, Figure 2 and Figure 3For example, six arc grooves 0611 are provided on the side wall of each turntable body 061. Taking any adaptive unit as an example, the adaptive unit includes 4 levels of crescent columns 062, wherein the first-level crescent column 062 is arranged in the arc groove 0611 of the turntable body 061 and can rotate on the arc surface of the arc groove 0611, and a second-level crescent column 062 is respectively arranged in each arc groove 0611 of the first-level crescent column 062, and a third-level crescent column 062 is respectively arranged in each arc groove 0611 of each crescent column 062 of the second level, and a fourth-level crescent column 062 is respectively arranged in each arc groove 0611 of each crescent column 062 of the third level. Correspondingly, it is still necessary to satisfy that each crescent column 062 is limited in the corresponding arc groove 0611 and can rotate on the arc surface of the corresponding arc groove 0611; for any turntable, the 4th-level crescent columns 062 on its two turntable bodies 061 can form a closed annular structure.

[0061] like Figure 4 , Figure 5 , Figure 6 As shown, in order to cooperate with the crescent column 062 and the arc groove 0611, U-shaped slide grooves 0612 are set at both ends of each arc groove 0611, and the notches of the two U-shaped slide grooves 0612 on each arc groove 0611 are set far away from each other, and the two ends of the arc wall of each crescent column 062 are fixedly connected to the arc slider 0622, and the two arc sliders 0622 on each crescent column 062 are respectively extended into the U-shaped slide grooves 0612 at both ends of the corresponding arc groove 0611, so that each crescent column 062 is limited in the corresponding arc groove 0611 and can rotate on the arc surface of the corresponding arc groove 0611.

[0062] Specifically, the crescent column 062 is limited in the corresponding arc groove 0611 through the cooperation of the U-shaped slide groove 0612 and the arc slider 0622, and the arc slider 0622 can slide in the U-shaped slide groove 0612, so that the crescent column 062 can slide on the arc surface of the arc groove 0611.

[0063] Among them, a limiting screw hole 0621 is provided on each crescent column 062, and a limiting groove 0613 is provided at each arc groove 0611. Each crescent column 062 is limited in the corresponding arc groove 0611 by a limiting screw passing through the corresponding limiting screw hole 0621 and the limiting groove 0613, and the arc of the limiting groove 0613 is 60 degrees.

[0064] In this embodiment, the crescent column 062 is further limited on the existing arc groove 0611 by the limiting screw. And the setting of the limiting groove 0613 will not hinder the rotation of the crescent column 062 on the arc surface of the arc groove 0611.

[0065] Among them, the supporting mechanism 02 includes a base, to which a chuck frame is fixedly connected, and the chuck frame is fixedly connected to the chuck body of the three-jaw chuck 01. A through hole is provided on the chuck frame, and the through hole is coaxially arranged with the center hole of the three-jaw chuck 01; the lower end of the base is fixedly connected to four support columns through an adapter plate, and the lower end of each support column is connected to a universal wheel.

[0066] The provision of the universal wheel in this embodiment facilitates moving the cable guiding mechanism to a corresponding position.

[0067] There are two three-jaw chucks 01, and the chuck body of each three-jaw chuck 01 is fixed on the support mechanism 02. The arrangement of two three-jaw chucks 01 makes the clamping and guiding of the cable body more stable, and when there are two three-jaw chucks 01, there are two corresponding chuck racks, and the center holes of the two three-jaw chucks 01 and the center holes of the two chuck racks are coaxially arranged,

[0068] When guiding the cable body, the cable body passes through the center hole of the three-jaw chuck 01 and the center hole of the chuck frame, and the square hole 011 of the bevel gear on the three-jaw chuck 01 is adjusted to perform manual clamping; the drive motor 03 is started, and the drive motor 03 is controlled to rotate forward or reverse at the same time, and the connecting shaft 04 is driven to rotate through the coupling 042 at the same time. The rotation of the connecting shaft 04 drives the two turntable bodies 061 to rotate, and the friction between the rotation of the turntable body 061 and the cable body drives the cable body to move.
