Description

Technical Field

[0001] The utility model relates to the field of marine engineering equipment, in particular to a cable winding device. Background Art

[0002] Winches, especially deep-sea winches, typically require separate cables. These cables can be quite long, reaching tens of thousands of meters. These cables are typically delivered wound around a drum. Cable winding equipment is required when the cable needs to be transported to the winch, or when the winch is replaced with a new one and the old cable is wound around the drum. Cable winding equipment typically uses a shaft to drive the drum to facilitate cable transportation and winding.

When installing the cable drum, it is necessary to adjust the height of the cable drum so that the cable drum and the rotating shaft are positioned relative to each other and connected to each other. The above operations make the installation of the cable drum more cumbersome and inefficient.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0037] When installing the cable drum, the existing cable winding equipment needs to adjust the cable drum height so that the cable drum and the rotating shaft are positioned relative to each other and are connected to each other. The above operations make the installation of the cable drum more complicated and inefficient.

[0038] In order to solve the above technical problems, this embodiment provides a cable winding device, please refer to Figures 1 to 4 As shown, Figure 1 is a three-dimensional diagram of the cable winding device in the embodiment, Figure 2 This is a top view of the cable winding device in the embodiment. Figure 3 This is a front view of the cable winding device in the embodiment. Figure 4 2 is a side view of the cable winding device in the embodiment.

[0039] A cable winding device of this embodiment, such as Figure 1 and Figure 3 As shown, it includes two cable winding devices 1 , and each cable winding device 1 includes a base 11 and a friction wheel assembly 12 .

[0040] The base 11 is used to install and support the friction wheel assembly 12 , thereby supporting the cable drum 2 .

[0041] Friction wheel assembly 12, such as Figure 1 and Figure 2 As shown, two groups are provided on each base 11. Each group of friction wheel assemblies 12 includes a friction wheel 121 and a driving mechanism 122. The friction wheel 121 is rotatably provided on the base 11, and the two groups of friction wheels 121 are spaced apart along the longitudinal direction; the driving mechanism 122 is provided on the base 11 and is transmission-connected to the friction wheel 121 for driving the friction wheel 121 to rotate.

[0042] The setting of the cable winding device 1 also needs to meet the following conditions: Figure 2As shown, the friction wheels 121 of the two cable winding devices 1 are used to jointly support the cable drum 2 and drive the cable drum 2 to rotate circumferentially through rotational friction; there are at least two relatively fixed positions between the bases 11 of the two cable winding devices 1. At different relatively fixed positions, the friction wheels 121 of the two cable winding devices 1 have different spacings in the transverse direction to accommodate cable drums 2 of different lengths.

[0043] The cable winding equipment of the above technical solution supports and drives the cable drum 2 to rotate through two cable winding devices 1. When installing the cable drum 2, the cable drum 2 is supported on the four sets of friction wheels 121 of the two cable winding devices 1 by hoisting or rolling. The driving mechanism 122 drives the four sets of friction wheels 121 to rotate synchronously, so that the friction wheels 121 can drive the cable drum 2 to rotate through friction transmission, thereby realizing the cable drum 2 to release and reel in the cable. Compared with the traditional cable winding equipment, which requires adjusting the height of the cable drum 2 and making the cable drum 2 and the rotating shaft 124 relative and socketed, the installation method is simpler and more efficient. At the same time, this method of supporting and driving the cable drum 2 with the friction wheel 121 is suitable for cable drums 2 of different diameters. The bases 11 of the two cable winding devices 1 have at least two relatively fixed positions. Since the friction wheels 121 of the two cable winding devices 1 are spaced at different distances in the lateral direction at different relatively fixed positions, the friction wheels 121 of the two cable winding devices 1 can be adjusted to accommodate cable drums 2 of different lengths by adjusting the relative fixed position between the bases 11. Therefore, the cable winding device has good applicability to cable drums 2 of different diameters and lengths. It can be seen that the cable winding device of the above technical solution is suitable for cable drums 2 of different sizes and specifications, simplifies the installation operation of the cable drum 2, and has the advantages of ease of use and high efficiency.

[0044] Each friction wheel assembly 12 may include one or more friction wheels 121 , which may be set according to specific needs.

[0045] Exemplarily, each friction wheel assembly 12 includes a friction wheel 121 (not shown), and the two cable winding devices 1 have a total of four friction wheels 121 to meet the basic support and drive requirements of the cable drum 2. At this time, the friction wheel 121 can be directly connected to the base 11 through the wheel axle.

[0046] For example, see Figure 1 and Figure 2 As shown, each group of friction wheel assemblies 12 includes at least two friction wheels 121, and a necking structure is formed between the friction wheels 121 of each cable winding device 1, and the opening of the necking structure gradually decreases from top to bottom, that is, the friction wheels 121 of the same group are arranged around the circular edge of the cable drum 2 when supporting the cable drum 2, so that all friction wheels 121 contact the cable drum 2 at the same time. The cable drum 2 is supported and driven by more friction wheels 121, so that the placement and rotation of the cable drum 2 are smoother.

[0047] In one embodiment, the friction wheel 121 is rotatably mounted on the base 11. Figure 1 and Figure 2 As shown, the friction wheel assembly 12 includes a swing frame 123 and a rotating shaft 124. The rotating shaft 124 is rotatably connected to the base 11 and is in transmission connection with the drive mechanism 122. The swing frame 123 is rotatably mounted on the rotating shaft 124. The friction wheels 121 are rotatably connected to the swing frame 123 and are in transmission connection with the rotating shaft 124 via a gear set 125. The swing frame 123 can swing relative to the rotating shaft 124 and the base 11 to adjust the angles of the friction wheels 121 so that all friction wheels 121 contact the cable drum 2 simultaneously. During operation, the drive mechanism 122 drives the rotating shaft 124 to rotate, and the rotating shaft 124 drives the friction wheels 121 to rotate via the gear set 125.

[0048] For example, see Figure 1 and Figure 3 As shown, a bearing seat 126 is fixed on the base 11 , and the rotating shaft 124 is connected to the bearing seat 126 via a bearing, so that it can rotate relative to the base 11 .

[0049] The driving mechanism 122 and the rotating shaft 124 can be connected to each other by using existing gear transmission, chain transmission and other transmission methods, or by using the following transmission methods:

[0050] See Figure 1 and Figure 2 As shown, in this transmission method, the drive mechanism 122 includes a drive motor 1201, a driving pulley 1202, a synchronous belt 1203, and a driven pulley 1204. The drive motor 1201 is fixed to the base 11. There are two driving pulleys 1202 connected to the output shaft of the drive motor 1201. There are two driven pulleys 1204, each connected to the two driving pulleys 1202 via a synchronous belt 1203, and respectively connected to the rotating shafts 124 of the two friction wheel assemblies 12. In this transmission method, a single drive motor 1201 can synchronously drive two sets of friction wheel assemblies 12, causing the friction wheels 121 of the same cable winding device 1 to rotate synchronously at the same speed. Combined with the equal operating power of the two drive motors 1201, the synchronous and smooth driving of the cable drum 2 by the friction wheels 121 is improved.

[0051] For example, see Figure 1 As shown, the gear set 125 includes a driven gear and a driving gear. A driven gear is fixedly connected to the axle of each friction wheel 121. The driving gear is fixedly connected to the rotating shaft 124 and is also connected to each driven gear, thereby driving each driven gear and the corresponding friction wheel 121 to rotate.

[0052] For example, see Figure 1 and Figure 3As shown, the swing frame 123 includes two swing plates 1230 that are spaced apart and relatively fixed. The friction wheel 121 is connected between the swing plates 1230 through the rotation of the wheel axle, and a channel for limiting the lateral movement of the cable drum 2 is formed between the two swing plates 1230. That is, when the cable drum 2 is supported on the friction wheel 121, the two swing plates 1230 are respectively located on the opposite sides of the supporting part of the cable drum 2, thereby preventing the cable drum 2 from disengaging from the friction wheel 121 in the lateral direction.

[0053] In order to make the swing frame 123 more stable when supporting and driving the cable drum 2, refer to Figure 3 and Figure 5 As shown, Figure 5 The figure is a three-dimensional diagram of the adjustment mechanism in the embodiment. Each cable winding device 1 also includes an adjustment mechanism 13, which includes a limit frame 131, a bracket 132, and an adjustment bolt 133. The limit frame 131 is fixedly connected to the base 11, and the bracket 132 is fixedly connected to the swing frame 123. The above two fixed connections can be achieved by welding or bolting. The adjustment bolt 133 is threadedly connected to the bracket 132 and can be locked with a nut. The limit frame 131 is provided with a limit hole 1310, and the adjustment bolt 133 is located in the limit hole 1310. When the friction wheel 121 jointly supports the cable drum 2, the swing frame 123 abuts against the inner side of the limit hole 1310 via the limit bolt, thereby limiting the relative angle between the swing frame 123 and the base 11, preventing the swing frame 123 from further rotating. The adjustment bolt 133 is used to adjust and fix the relative position with the bracket 132 to adjust the aforementioned relative angle.

[0054] For example, see Figure 3 and Figure 5 As shown, the limit frame 131 is located on the side of the swing frame 123 away from the cable drum 2. When the cable drum 2 is supported on the friction wheel 121, it can drive the swing frame 123 to rotate toward the cable drum 2, so that each friction wheel 121 is in contact with the cable drum 2 at the same time. In order to maintain this simultaneous contact state, the limit frame 131 is provided with a longitudinally opened limit hole 1310, and the bracket 132 partially extends into the limit hole 1310, and the adjusting bolt 133 is connected to the extended part and is fixed relative to the bracket 132 by a thread or a nut. The top of the adjusting bolt 133 abuts against the top of the limit hole 1310, thereby limiting the bracket 132 and the swing frame 123 from continuing to rotate toward the cable drum 2, thereby realizing the limiting function.

[0055] The two bases 11 of the above-mentioned two cable winding devices 1 have at least two relatively fixed positions, which can be achieved by the following methods: Figure 1 and Figure 3As shown, the bases 11 of the two cable winding devices 1 are connected by an adjusting structure, which includes connecting holes 111 and connecting bolts 112. Each base 11 is provided with at least two connecting holes 111 spaced apart in the transverse direction. The number and spacing of the connecting holes 111 can be set according to the preset length of the cable drum 2. The connecting bolts 112 pass through any two opposite connecting holes 111 on the two bases 11 and fix the two bases 11. Different connecting holes 111 are connected by the connecting bolts 112, so that there are at least two relatively fixed positions between the two bases 11.

[0056] For example, see Figure 1 and Figure 3 As shown, three connection holes 111 are provided at equal intervals on both sides of each base 11 , and the same side is connected by at least one adjusting bolt 133 so that the bases 11 are fixed at a preset relative fixed position.

[0057] The two bases 11 of the above-mentioned two cable winding devices 1 have at least two relatively fixed positions, which can also be achieved in the following way: slide rails and sliders (not shown) are respectively provided on the two bases 11, and are connected by the slide rails and sliders so that the two bases 11 can slide relative to each other to adjust the spacing to adapt to cable drums 2 of different lengths. At the same time, after adjusting the spacing, the relative position can be fixed by bolts.

[0058] In order to increase friction, reduce wear on the surface of the cable drum 2, and enhance the rotation stability of the cable drum 2, the wheel surface of the friction wheel 121 is provided with a rubber skin, and contacts the cable drum 2 through the rubber skin.

[0059] Exemplarily, the rubber sheet is annular and is sleeved on the outer periphery of the friction wheel 121 , and the wheel surface of the friction wheel 121 is bonded and fixed to the rubber skin.

[0060] In some embodiments, see Figure 2 and Figure 3 As shown, the friction wheel assemblies 12 of the two cable winding devices 1 of the cable winding equipment are symmetrically arranged. In a top view, the center of symmetry is the center line of the length direction of the cable drum 2 or the axis of the cable drum 2.

[0061] In some embodiments, see Figure 2 and Figure 3 As shown, the friction wheel 121 has a certain length so as to be applicable to cable drums 2 of a certain length range without adjusting the spacing between the bases 11 .

[0062] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
