Description

Technical Field

[0001] The present invention relates to the technical field of cable winding equipment, and in particular to an easy-to-throw automatic cable winding cone and a winding method. Background Art

[0002] Cable winding devices have important applications in the fields of maritime rescue, ship mooring, etc. In the existing technology, cable winding devices mostly use mechanical reciprocating motion to achieve winding. However, such devices have significant defects in practical applications: due to the use of a multi-layer winding method, cross-extrusion is prone to occur between cable layers, resulting in a significant increase in friction when releasing the cable, causing poor cable release; at the same time, the uneven distribution of winding stress can easily cause local twisting and knotting of the cable. In scenarios where high-speed cable throwing is required (such as emergency rescue), existing devices are difficult to meet the needs of fast and low-resistance throwing due to excessive release resistance. Therefore, there is an urgent need for a winding device that can achieve high-speed cable throwing to solve the above technical problems. Summary of the Invention

[0003] The purpose of the present invention is to provide an automatic cable winding cone and winding method that is easy to throw, so as to solve the problems existing in the above-mentioned prior art, avoid friction loss and entanglement risk between cables, and solve the problem that cables cannot be thrown at high speed in specific scenarios.

[0004] To achieve the above object, the present invention provides the following solutions:

[0006] A conical winding roller comprises a base and a plurality of fins arranged on the base, wherein the plurality of fins are arranged in a circumferential array on the base to form a frustum structure, and the conical surface of the frustum structure is used for winding the cable uniformly in a single layer;

[0007] A cable arranging frame is provided on one axial side of the conical winding roller and is used to guide the cable to be arranged along the conical surface;

[0008] A rotating platform is coaxially connected to the conical winding roller and is used to drive the conical winding roller to rotate under the drive of a rotary drive mechanism;

[0009] a displacement brake connected to the wire traversing frame and used to control the horizontal displacement of the wire traversing frame according to the number of winding turns;

[0010] The cable restraint mechanism includes a telescopic assembly and multiple sets of one-to-one corresponding connecting rods and tensioning members, one end of the connecting rod is hinged to the movable end of the telescopic assembly, the other end is hinged to the first end of the tensioning member, and the second end of the tensioning member is hinged to the base; the multiple tensioning members are spaced apart from the multiple fins of the conical winding roller, and the telescopic assembly drives the tensioning member to switch between the cable winding state and the cable throwing state through the multiple connecting rods, wherein,

[0011] Cable reeling state: the plurality of tensioning members are in an open state, so that their outer circumferences form a support surface for the cable and apply radial tension to the cable;

[0012] Cable dropping state: the plurality of tensioning members are retracted to be separated from the cable, and the tensioning effect is cancelled.

[0013] In an exemplary embodiment, the fin is a curved plate, and the outer side surface of the curved plate is flush with the outer side surface of the tensioning member when it is expanded, forming a continuous supporting surface.

[0014] In an exemplary embodiment, the tapered winding roller has a taper angle ranging from 5° to 15°.

[0015] In an exemplary embodiment, the outer side surface of the curved plate is provided with an anti-slip texture.

[0016] In an exemplary embodiment, the displacement brake includes an encoder and a servo motor. The encoder detects the number of rotations of the conical winding roller in real time and feeds back to the servo motor to control the displacement of the wire rack.

[0017] In an exemplary embodiment, an anti-unhooking claw is provided at the end of the tensioning member.

[0018] In an exemplary embodiment, a tension sensor is provided on the wire rack, and the tension sensor monitors the cable tension in real time and feeds back to the displacement brake to adjust the displacement speed of the wire rack.

[0019] The present invention also provides a cable winding method based on the above-mentioned cable winding cone, comprising the following steps:

[0020] Step 1: Control the telescopic assembly to drive the plurality of tensioning members to open, and fix the starting end of the cable to the small diameter end of the tapered winding roller;

[0021] Step 2: Start the rotating platform to drive the conical winding roller to rotate, and at the same time control the horizontal displacement of the wire rack by the displacement brake, so that the cable is wound in a single layer along the conical surface of the conical winding roller;

[0022] Step 3: After the winding is completed, the telescopic assembly is controlled to retract the tensioning member to release the cable;

[0023] Step 4: After the throwing is completed, the telescopic assembly is controlled to reset so that the tensioning member returns to the open state.

[0024] In an exemplary embodiment, in step 2, the displacement brake calculates the real-time displacement of the cable rack based on the rotational angular velocity and the taper value of the conical winding roller to ensure that the distance between adjacent turns of the cable is constant.

[0025] In an exemplary embodiment, in step 3, during the cable dropping process, the conical winding roller is freely rotated by an external tension, and the cable is released from the small diameter end to the large diameter end of the conical winding roller.

[0026] Compared with the prior art, the present invention has achieved the following technical effects:

[0027] By installing a conical winding roller composed of multiple fins and winding the cable uniformly around the conical surface in a single layer, the cable only needs to overcome friction between the cable and the conical roller surface during release, significantly reducing frictional losses and the risk of entanglement between the cables. The gaps formed between adjacent fins reduce the contact area between the conical roller surface and the cable, further reducing frictional resistance during release. A tensioner is spaced apart from the fins and spaced apart from the fins. A telescopic assembly allows the tensioner to switch between cable reeling and cable release. During reeling, the tensioner opens to fill the gaps between the fins, forming a continuous support surface with the fins to ensure winding stability. During release, the tensioner retracts, exposing the gaps between the fins and limiting the cable to partial contact with the fins, significantly reducing frictional resistance and effectively resolving the problem of high-speed cable release in certain scenarios. Furthermore, the device automatically resets quickly after cable release, ensuring immediate entry into the next winding cycle and achieving a continuous and efficient reeling and release cycle.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. People familiar with this technology can easily understand other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] The purpose of the present invention is to provide an automatic cable winding cone and winding method that is easy to throw, so as to solve the problems existing in the prior art, avoid friction loss and entanglement risk between cables, and solve the problem that cables cannot be thrown at high speed in specific scenarios.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Example 1

[0039] Please refer to Figures 1 to 2 This embodiment provides an automatic cable winding cone that is easy to throw, including a conical winding roller 1, a wire rack 2, a rotating table 3 and a cable restraint mechanism 5.

[0040] The conical winding roller 1 includes a base 101 and a plurality of fins 102 arranged on the base 101. The plurality of fins 102 are arranged in a circular array on the base 101 to form a frustum structure. The conical surface of the frustum structure is used for winding the cable uniformly in a single layer.

[0041] The cable rack 2 is arranged on one axial side of the conical winding roller 1 and is used to guide the cable to be arranged along the conical surface.

[0042] The rotating table 3 is coaxially connected to the conical winding roller 1 and is used to drive the conical winding roller 1 to rotate under the drive of a rotation drive mechanism (not shown in the figure), wherein the rotating table 3 and the base 101 of the conical winding roller 1 can be an integrated structure.

[0043] The displacement brake 4 is used to install the wire rack 2 and control the horizontal displacement of the wire rack 2 according to the number of winding turns.

[0044] The cable restraint mechanism 5 includes a telescopic assembly 501 and multiple sets of one-to-one corresponding connecting rods 502 and tensioning members 503. The telescopic assembly 501 can adopt a controllable telescopic structure in the prior art, such as an electric telescopic rod or a hydraulic or pneumatic telescopic rod. One end of the connecting rod 502 is hinged to the movable end of the telescopic assembly 501, and the other end is hinged to the first end of the tensioning member 503. The second end of the tensioning member 503 is hinged to the base 101. The end of the tensioning member 503 is provided with an anti-unhooking claw 504; the multiple tensioning members 503 are spaced apart from the multiple fins 102 of the conical winding roller 1. The telescopic assembly 501 drives the tensioning member 503 to switch between the cable winding state and the cable releasing state through the multiple connecting rods 502, wherein:

[0045] Cable reeled state: multiple tensioning members 503 are in an open state, so that their outer circumferences form a support surface for the cable, and 503 applies radial tension to the cable;

[0046] Cable dropping state: the plurality of tensioning members 503 are retracted to be separated from the cable, and the tensioning effect is canceled.

[0047] By installing a conical take-up roller 1 composed of multiple fins 102 and wrapping the cable uniformly around the conical surface in a single layer, the cable only needs to overcome friction between the cable and the conical roller surface during release, significantly reducing frictional losses and the risk of entanglement. The conical structure guides the cable from the small end to the large end, minimizing the probability of knotting. The gaps between adjacent fins 102 reduce the contact area between the conical roller surface and the cable, further reducing frictional resistance during release.

[0048] By providing a tensioning member 503 spaced apart from the fins 102, and utilizing a telescopic assembly 501 to switch the tensioning member 503 between a cable reeling state and a cable releasing state, the device automatically resets itself after releasing the cable, ensuring immediate entry into the next winding cycle. During reeling, the tensioning member 503 expands to fill the gaps between the fins 102, forming a continuous support surface with the fins 102 and ensuring winding stability. During release, the tensioning member 503 retracts, exposing the gaps between the fins 102 and allowing only partial contact between the cable and the fins 102. This significantly reduces frictional resistance and effectively addresses the challenge of high-speed cable release in certain scenarios. Furthermore, the device automatically and quickly resets after releasing the cable, ensuring immediate entry into the next winding cycle and achieving a continuous and efficient reeling and reeling cycle.

[0049] In this embodiment, the fins 102 that make up the frustum structure are curved plates, the outer surfaces of which are flush with the outer surfaces of the tensioning member 503 when extended, forming a continuous support surface. Furthermore, the tapered roll 1 has a taper range of 5°-15°, meaning the inclination angle of the curved plates is 5°-15°.

[0050] The outer side of the curved plate is provided with anti-slip textures, such as serrations or grooves, to prevent slipping when rolling up.

[0051] The displacement brake 4 includes an encoder and a servo motor. The encoder detects the number of rotations of the conical winding roller 1 in real time and provides feedback to the servo motor to control the displacement of the wire draw frame 2. A tension sensor is installed on the wire draw frame 2. The tension sensor monitors the cable tension in real time and provides feedback to the displacement brake 4 to adjust the displacement speed of the wire draw frame 2.

[0052] The cable is wound along a spiral trajectory, starting from the small end of the cone. The circumference of each turn increases with the diameter of the cone. An encoder detects the speed of the conical winding roller 1 and calculates the theoretical cable displacement speed based on the taper parameters. A tension sensor provides feedback on the actual tension. If the tension deviates from the set value, such as due to elastic deformation of the cable, the servo motor adjusts the displacement speed in real time to ensure uniform winding.

[0053] Example 2

[0054] Please refer to Figures 3 to 5 This embodiment discloses a cable winding cone winding method based on the first embodiment, comprising the following steps:

[0055] Step 1: Figure 3 As shown, the telescopic assembly 501 is controlled to drive the multiple tensioning members 503 to open, so that the outer side surface of the tensioning member 503 slightly exceeds the conical surface of the conical winding roller 1, and the starting end of the cable is fixed to the small diameter end of the conical winding roller 1;

[0056] Step 2: Figure 4 As shown, the rotary drive mechanism is started to drive the rotary table 3 to drive the conical winding roller 1 to rotate at a constant speed. Figure 4 The example is counterclockwise rotation, while the horizontal displacement of the wire rack 2 is controlled by the displacement brake 4, so that the cable is wound in a single layer along the conical surface of the conical winding roller 1;

[0057] Among them, the displacement brake 4 calculates the real-time displacement of the cable rack 2 according to the rotation angular velocity and taper value of the conical winding roller 1 to ensure that the distance between adjacent turns of the cable is constant;

[0058] Step 3: After the winding is completed, the telescopic assembly 501 is controlled to retract the tensioning member 503, and the cable falls from the tensioning member 503 to the conical winding roller 1. External traction, such as the pulling force of the rescue equipment, pulls the cable, and the cable is released from the large end to the small end. Since the cable is only placed on the conical winding roller 1 at this time, and there is even a certain gap between the cable and the conical winding roller 1, there is basically no friction when the external traction pulls the cable;

[0059] Step 4: After the casting is completed, the telescopic assembly 501 is controlled to reset, so that the tensioning member 503 returns to the open state, and the wire rack 2 returns to the initial position to prepare for the next round of winding.
