Description

Technical Field

[0001] This invention relates to the field of cable crimping technology, and more specifically, to a cable crimping device for segmented variable-parameter flow cables. Background Technology

[0002] Flow cables, due to their advantages of low resistance, good towing stability, low noise, and high depth-keeping efficiency, have been fully utilized in deep-sea towing systems. However, the inherent difficulty in cable laying of flow cables has limited their further promotion. Currently, there are several effective methods for laying single-parameter flow cables, mainly including pre-set cable grooves and pre-loaded deflection methods.

[0003] The pre-grooved cable method involves pre-grooving a certain depth of groove on the drum. The cable lies within the groove, maintaining an upright position during cable laying. This method has a wide range of applications, but its disadvantages include low winch cable capacity and high dependence on cable parameters; generally, one type of groove is used for each type of cable. The pre-loaded deflection method involves forcibly deflecting the cable at a certain angle before it is wound onto the winch, ensuring that the cable maintains a necessary unidirectional inclination while winding on the winch. This method also achieves efficient cable laying, but it is only suitable for one type of cable. In practical applications, sometimes the parameters of the cable sections on a single cable are segmented, with each segment having different parameters. Currently, there is no good method for handling this type of cable. Summary of the Invention

[0004] The purpose of this invention is to address the technical problems existing in the prior art by providing a cable pressing device for segmented variable parameter flow cables, which can realize the arrangement of segmented variable parameter flow cables at the same inclination angle, thereby achieving neat cable arrangement on the winch drum.

[0005] To address the problems mentioned above, the technical solution adopted by this invention is as follows:

[0006] The present invention provides a cable crimping device for segmented variable parameter current cables, comprising a first ball assembly, a first ball seat assembly, a second ball assembly, a second ball seat assembly, an adjusting screw assembly, and a cable crimping plate, wherein the cable crimping plate comprises a bottom cable crimping section, a middle cable crimping section, and a high cable crimping section;

[0007] The cable clamping plate has a first ball bearing seat group and a second ball bearing seat group respectively on its high-end and middle-end cable clamping parts, and each is connected and adjusted by an adjusting screw group. The ends of the first ball bearing seat group and the second ball bearing seat group that protrude from the side of the cable clamping plate are also movably provided with a first ball bearing group and a second ball bearing group, which cooperate with the surface of the cable to clamp the cable. The bottom cable clamping part forms an inclined surface on the surface corresponding to the cable, and the thickness gradually decreases from the middle end to the bottom end.

[0008] Furthermore, the middle and high end cable clamping portions have the same thickness and are located on the same plane; the length of the first ball bearing seat group protruding from the surface of the high end cable clamping portion is greater than the length of the second ball bearing seat group protruding from the surface of the middle end cable clamping portion.

[0009] Furthermore, the cable pressing plate is provided with a first countersunk hole and a second countersunk hole that penetrates the opposite side, and the first ball bearing seat group and the second ball bearing seat group are located at one end of the corresponding first countersunk hole and the second countersunk hole; the other end of the first countersunk hole and the second countersunk hole are respectively provided with an adjusting screw group.

[0010] Furthermore, the ball seats of the first ball seat assembly and the second ball seat assembly are respectively provided with arc-shaped grooves for mounting the first ball seat assembly and the second ball seat assembly.

[0011] Furthermore, the first ball bearing assembly and the second ball bearing assembly each include one or more ball bearings, the positions of the ball bearings in both align one-to-one and are located on the same axis; the first ball bearing assembly and the second ball bearing assembly each include one or more corrosion-resistant balls.

[0012] Furthermore, the ball bearing seat is provided with a through hole communicating with the arc-shaped groove for filling with lubricant.

[0013] Furthermore, the width of the cable clamping plate is not less than 1.5 times the width of the guide plate in the cable.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1) The cable pressing device of the present invention can meet different flow cable parameters. That is, the bottom cable pressing part forms an inclined surface with a thinner thickness to achieve the pre-pressing angle of the flow cable and is directly applicable to shorter flow cables. The middle and high cable pressing parts are respectively provided with ball bearing seats and corresponding balls, that is, two sets of cable pressing contacts are provided. By preset contact positions, the segmented variable parameter flow cables can be automatically identified and laid with the same angle. The structure is simple, the installation is convenient, and the work efficiency is improved.

[0016] 2) The present invention uses corrosion-resistant balls and ball seats in a rolling fit. The cable pressing contact formed by the two ensures that the corrosion-resistant balls form rolling friction when they are in contact with the working flow cable, which can ensure that the flow cables are not scratched or damaged during cable laying. The ball seats are used to fix the balls to prevent them from falling off. The two are easy to install and fit together.

[0017] 3) In this invention, the length of the first ball bearing seat group protruding from the surface of the high-end cable pressing part is greater than the length of the second ball bearing seat group protruding from the surface of the middle cable pressing part. That is, multiple sets of cable pressing contacts are provided, and the height and position of the cable pressing contacts can be changed, so as to meet different flow cable parameters.

[0018] 4) The cable pressing plate of the present invention is provided with an arc-shaped groove, which facilitates the installation of corrosion-resistant balls and ensures that the corrosion-resistant balls form rolling friction when they are in contact with the cable. A through hole connected to the arc-shaped groove is provided for filling with lubricant, which ensures that the corrosion-resistant balls can roll flexibly and also ensures the reliability of the cable pressing device.

[0028] See Figure 1 and Figure 2 As shown, the present invention provides a cable crimping device for segmented variable parameter current cables, including a first ball assembly 11, a first ball seat assembly 12, a second ball assembly 21, a second ball seat assembly 22, an adjusting screw assembly 3, and a cable crimping plate 4. The cable crimping plate 4 includes a bottom cable crimping part 41, a middle cable crimping part 42, and a high cable crimping part 43.

[0029] The cable clamping plate 4 has a first ball bearing seat group 12 and a second ball bearing seat group 22 respectively on its high-end cable clamping part 43 and middle-end cable clamping part 42, and each is equipped with an adjusting screw group 3 for connection and adjustment. The ends of the first ball bearing seat group 12 and the second ball bearing seat group 22 that protrude from the side of the cable clamping plate 4 are also respectively provided with a first ball bearing group 11 and a second ball bearing group 21, which engage with the surface of the cable to clamp the cable. The bottom cable clamping part 41 has a sloped surface corresponding to the cable, and its thickness gradually decreases from the middle end to the bottom end.

[0030] Specifically, the first ball bearing assembly 11 and the second ball bearing assembly 21 are in contact with the corresponding first ball bearing seat assembly 12 and the second ball bearing seat assembly 22 and can roll freely. The first ball bearing seat assembly 12 and the second ball bearing seat assembly 22 are connected by the corresponding adjusting screw assembly 3, so as to facilitate the adjustment of the length of the two protruding from the side of the cable pressing plate 4.

[0031] In this embodiment, the first ball bearing seat group 12 and the first ball bearing group 11, the second ball bearing seat group 22 and the second ball bearing group 21 respectively form different cable clamping contacts, which facilitates automatic identification of flow cables with different parameters. Different cable clamping contacts can act on the side of flow cables with different parameters.

[0032] Furthermore, the middle cable clamping part 42 and the high-end cable clamping part 43 have the same thickness and are located on the same plane; the length of the first ball bearing seat group 12 protruding from the surface of the high-end cable clamping part 43 is greater than the length of the second ball bearing seat group 22 protruding from the surface of the middle cable clamping part 42.

[0033] Furthermore, the cable clamping plate 4 is provided with a first countersunk hole and a second countersunk hole that penetrates the opposite side, and the first ball bearing seat group 12 and the second ball bearing seat group 22 are located at one end of the corresponding first countersunk hole and the second countersunk hole; the other end of the first countersunk hole and the second countersunk hole is respectively provided with an adjusting screw group 3.

[0034] Specifically, the adjusting screw group 3 in the first countersunk hole and the second countersunk hole are respectively connected to the corresponding first ball bearing seat group 12 and the second ball bearing seat group 22, which serve to fix them and can adjust the length of the two protruding from the surface of the cable pressing plate 4, so that the ends of the first ball bearing group 11 and the second ball bearing group 21 are located on different planes, thereby accommodating different parameters of the cable and playing the role of pressing the cable.

[0035] Furthermore, the ball seats of the first ball seat assembly 12 and the second ball seat assembly 22 are respectively provided with arc-shaped grooves to facilitate reliable installation and engagement with the first ball seat assembly 11 and the second ball seat assembly 21.

[0036] Furthermore, the first ball bearing assembly 12 and the second ball bearing assembly 22 each include one or more ball bearing seats, the positions of which correspond one-to-one and are located on the same axis, making installation convenient and functionality reliable. The first ball bearing assembly 11 and the second ball bearing assembly 21 each include one or more corrosion-resistant balls.

[0037] Furthermore, the ball bearing seat is provided with a through hole that communicates with the arc-shaped groove, which serves as an oil groove for filling with lubricant, ensuring that the corrosion-resistant ball bearing 1 can roll flexibly and that the cables are not scratched or damaged during cable laying.

[0038] Furthermore, the width of the cable clamping plate 4 is not less than 1.5 times the width of the guide plate in the cable, that is, the width is greater than or equal to 1.5 times the width of the guide plate in the cable, so that the cable clamping plate 4 can reliably act on the cable and achieve reliable cable clamping. Specifically, the widths of both the cable clamping plate 4 and the guide plate in the cable can be adjusted according to actual needs to ensure the reliability of the cable clamping device.

[0039] The cable pressing device of the present invention secures the entire assembly to the cable guiding device by means of the cable pressing plate 4, so that the segmented variable parameter flow cable can enter the winch drum at the same tilt angle. Figure 3 The diagram shows three different types of flow cables. The flow cable includes a flow guide plate 100 and a trailing cable 200 wound on the flow guide plate 100. The length of the flow guide plate 100 increases from short to long. According to the parameters of different flow cables, in order to ensure that the variable parameter flow cables can achieve a uniform cable pressing angle, the cable pressing plate 4 is divided into sections, namely, a bottom cable pressing section 41, a middle cable pressing section 42, and a high-end cable pressing section 43.

[0040] Figure 4 As shown, for cable type 1, the inclined surface on the bottom cable clamping part 41 is pressed against the side of the guide plate 100 in the cable; for cable type 2, the inclined surface on the bottom cable clamping part 41 is pressed against the side of the guide plate 100 in the cable, and the second ball set 21 on the middle cable clamping part 42 acts on the end of the guide plate 100; for cable type 3, the inclined surface on the bottom cable clamping part 41 is pressed against the side of the guide plate 100 in the cable, the second ball set 21 on the middle cable clamping part 42 acts on the middle of the guide plate 100, and the first ball set 12 on the high-end cable clamping part 43 acts on the end of the guide plate 100.

[0041] In the above, the cable pressing plate 4 is segmented. During operation, the guide plates 100 of the flow cable are all subjected to force on the side of the cable pressing device. Flow cables of different line types can contact the corrosion-resistant balls at the corresponding positions. Under the action of this force, the shape of the flow cable changes according to the preset deflection angle through rolling friction. This can effectively identify the segmented variable parameter flow cables and make them all reach the preset uniform cable pressing angle. Finally, the flow cables with three different parameters can be successfully laid out with the same deflection angle.

[0042] The cable pressing device provided by this invention enables different types of cables on the same cable to be laid out at the same deflection angle. It has a simple structure, is easy to install, and has a high degree of automation, making it highly practical and applicable.

[0043] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
