Description

Technical Field

[0001] This application relates to the field of winch technology, and in particular to optical fiber cable winches. Background Technology

[0002] In marine exploration operations, it is necessary to lower detection instruments to the seabed for exploration. Typically, the instruments are connected to the exploration vessel via fiber optic cables, and a winch is used to release and reel in the cables, enabling the instruments to transmit clear data to the vessel from the ocean. In existing technology, the winch typically directly reels in the fiber optic cables, winding them onto the winch drum.

[0003] Regarding the aforementioned technologies, the inventors believe that when the winch rapidly winds up the optical cable, the optical cable is wound too loosely in some parts of the drum, causing it to slip off the drum and affecting the winding of the optical cable. Utility Model Content

[0004] The purpose of this application is to provide an optical cable winch to improve the problem that when the winch is rapidly winding optical cables, some parts of the cable on the drum are wound too loosely, causing the optical cable to slip off the drum and affecting the winding of the optical cable.

[0005] The optical cable winch provided in this application adopts the following technical solution:

[0006] An optical cable winch includes a winch bracket, a drum rotatably mounted on the winch bracket, a drive unit for driving the drum to rotate and winding the optical cable, and support frames at both ends of the winch bracket and below the drum, each support frame having a rotating roller that abuts against the optical cable wound on the drum.

[0007] By adopting the above technical solution, the drive unit on the winch support drives the drum to wind up the optical cable. A rotating roller is rotatably connected to the support frame located at both ends of the winch support below the drum. When the drum winds up the optical cable, it abuts against the optical cable wound on the drum. The rotating roller abuts against the optical cable on the drum and rotates with the drum as it winds up the optical cable, thus supporting the optical cable on the drum. This reduces the impact of the already wound optical cable on the drum loosening and slipping during the winding process.

[0008] Optionally, the first support frame is rotatably connected to a rotating shaft, and the rotating roller is sleeved on the outside of the rotating shaft. Each rotating shaft has several rotating rollers, which are arranged sequentially along the axial direction of the rotating shaft. A second support frame is provided on the side of the first support frame away from the rotating shaft. The second support frame has a fixing hole. A fixing rod is provided on the side of the first support frame close to the second support frame, which is inserted into the fixing hole. An elastic element is provided on the outside of the fixing rod between the first support frame and the second support frame.

[0009] By adopting the above technical solution, a rotating shaft is rotatably connected to the support frame one. Several rotating rollers on each rotating shaft are arranged sequentially along the axial direction of the rotating shaft, so that the rotating rollers can support the optical cable between the side plates of the drum and prevent the optical cable from contacting the support frame. The elastic element one is installed on the outside of the fixed rod between the support frame one and the support frame two. When the diameter of the optical cable wound on the drum increases, the rotating rollers start to push the support frame one towards the support frame two as the diameter of the wound optical cable increases. The elastic element one pushes the support frame one so that the rotating rollers always abut against the optical cable, preventing the optical cable on the drum from loosening and slipping off.

[0010] Optionally, a baffle is provided on the side of the second support frame away from the drum, and the baffle abuts against the side of the first support frame away from the drum.

[0011] By adopting the above technical solution, a baffle is provided on the side of the second support frame away from the drum, which abuts against the first support frame to prevent the first support frame from tilting and detaching from the second support frame under the action of the expanded optical cable on the drum, so that the optical cable on the drum loses its support.

[0012] Optionally, the winch bracket is provided with a sliding groove along the radial direction of the drum below the second support frame. The second support frame is slidably connected to the sliding groove. The second support frame is provided with a connecting hole, in which a sliding rod connected to the inner sidewall of the sliding groove is inserted.

[0013] By adopting the above technical solution, a sliding groove is opened in the radial direction of the drum below the winch support frame 2. The sliding rod set in the sliding groove is inserted into the connecting hole of the support frame 2 to prevent the support frame 2 from falling out of the sliding groove. After the support frame 1 moves to the limit, the support frame 2 moves away from the support frame 1 in a direction away from the drum, so that the rotating roller moves away from the optical cable that gradually expands after being wound on the drum, preventing the optical cable from being damaged by the squeezing of the roller and the drum.

[0014] Optionally, a fixing block is provided at one end of the winch bracket near the second support frame, and an elastic element is provided between the fixing block and the baffle.

[0015] By adopting the above technical solution, an elastic element 2 is set between the fixed block and the baffle. The elastic element 2 pushes the support frame 2 to move in the slide groove, so that the rotating roller on the support frame 1 always abuts against the optical cable on the drum, reducing the possibility of the part of the optical cable wound on the drum becoming loose and slipping off.

[0016] Optionally, the outer side of the rotating roller is fitted with an elastic sleeve that abuts against the optical cable.

[0017] By adopting the above technical solution, an elastic sleeve made of rubber is sleeved on the outside of the rotating roller, so that the optical cable is in contact with the elastic sleeve on the rotating roller. At the same time, it can support the layer of optical cable inside the layer of optical cable that the drum is winding, so that the rotating roller can better support the optical cable on the drum.

[0018] Optionally, the winch bracket is provided with a mounting frame at the end away from the drum, the mounting frame is rotatably equipped with a reciprocating screw, the reciprocating screw is equipped with a movable frame, the movable frame is rotatably equipped with rollers for receiving optical cables, and a second driving component is provided on one side of the mounting frame to drive the reciprocating screw to rotate and cause the movable frame to move back and forth.

[0019] By adopting the above technical solution, a movable frame is set on the reciprocating screw, and the optical cable is supported by the rollers of the movable frame. The reciprocating screw is driven to rotate by the second drive component, so that the movable frame moves back and forth, so that the optical cable is evenly arranged on the drum when the drum is wound up, reducing the accumulation of optical cable in the drum section and reducing the possibility of the optical cable slipping off.

[0020] Optionally, the movable frame has a mounting hole, the mounting frame is provided with a guide rod that can be inserted into the mounting hole, and the arc surface of the roller has a groove that fits with the optical cable.

[0021] By adopting the above technical solution, when the moving frame moves back and forth with the reciprocating screw, the guide rod supports the moving frame to prevent the moving frame from deflecting on the reciprocating screw. Grooves are opened on the arc surface of the roller to reduce the possibility of the optical cable detaching from the roller when it is supported by the roller and moves with the moving frame.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The drive unit on the winch support drives the drum to wind up the optical cable. Rotary rollers are rotatably connected to the support frame located at both ends of the winch support below the drum. When the drum winds up the optical cable, the rollers abut against the optical cable wound on the drum. The rotating rollers abut against the optical cable on the drum and rotate with the drum as it winds up the optical cable, thus supporting the optical cable on the drum and reducing the impact of the already wound optical cable on the winding of the optical cable during winding.

[0024] 2. A rotating roller is rotatably connected to the rotating shaft on the support frame one. The rotating roller is installed at the interval between the rotating shaft and the rotating part of the support frame one and the rotating shaft, so that the rotating roller can support the optical cable between the side plates of the drum and prevent the optical cable from contacting the support frame. The elastic element one is installed on the outside of the fixed rod between the support frame one and the support frame two. When the diameter of the optical cable wound on the drum increases, the rotating roller starts to push the support frame one towards the support frame two as the diameter of the optical cable wound increases. The elastic element one pushes the support frame one so that the rotating roller always abuts against the optical cable and prevents the optical cable on the drum from loosening and slipping off.

[0025] 3. After the support frame 1 moves to its limit, the second support frame, along with the first support frame, moves away from the drum along the slide groove, so that the rotating roller moves away from the gradually expanding optical cable on the drum after winding, preventing the optical cable from being damaged by the compression between the roller and the drum; the second elastic element is set between the fixed block and the baffle, and the second elastic element pushes the second support frame to move in the slide groove, so that the rotating roller on the first support frame is always in contact with the optical cable on the drum, reducing the possibility of the part of the optical cable wound on the drum becoming loose and slipping off.

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0031] Optical cable winch, refer to Figure 1 and Figure 2The system includes a winch support 1, which is rotatably connected to the shafts at both ends of the drum 11 via bearings. A drive component 12 is bolted to the outside of the winch support 1. The drive component 12 is a high-power drive motor connected to a power source. The drive end of the drive motor drives the drum 11 to rotate and wind up the optical cable via a reducer. Support frames 2 are provided at both ends of the winch support 1 below the drum 11. Rotating rollers 21 are installed on the support frames 2. When the drum 11 winds up the optical cable, the rotating rollers 21 abut against the optical cable wound on the drum 11, supporting the optical cable that shows signs of loosening on the drum 11 and reducing the possibility of the wound optical cable on the drum 11 becoming loose and slipping off when the drum 11 winds up the optical cable.

[0032] Reference Figure 2 and Figure 3 The support frame 12 is rotatably connected to the rotating shaft 22 via bearings. Several rotating rollers 21 are sequentially mounted on the rotating shaft 22 along its axial direction, ensuring that the rotating rollers 21 support the optical cables between the side plates of the drum 11 and preventing contact between the optical cables and the support frame. Elastic rubber sleeves 211 are fitted around the outside of the rotating rollers 21, allowing the optical cables to adhere to the elastic sleeves 211 and simultaneously supporting the layer of optical cables being wound on the drum 11. Below the support frame 12, a... The device is equipped with a second support frame 3, on which a fixing hole 31 is opened. A fixing rod 23 is welded to the bottom of the first support frame 2 and inserted into the fixing hole 31. A spring, which serves as an elastic element 24, is installed on the outside of the fixing rod 23 between the first support frame 2 and the second support frame 3. When the diameter of the optical cable wound on the drum 11 increases, the rotating roller 21 begins to push the first support frame 2 towards the second support frame 3 as the diameter of the optical cable wound increases. The elastic element 24 pushes the first support frame 2 so that the rotating roller 21 always abuts against the optical cable, preventing the optical cable on the drum 11 from loosening and slipping off.

[0033] Reference Figure 2 and Figure 3A groove 13 is provided in the winch support 1 below the second support frame 3 along the radial direction of the drum 11. A connecting hole 33 is provided below the second support frame 3. A sliding rod 14 is welded to the inner wall of the groove 13 so that the sliding rod 14 is inserted into the connecting hole 33. After the first support frame 2 moves down to its limit, the second support frame 3 moves the first support frame 2 away from the drum 11. A baffle 32 is welded on the side of the second support frame 3 away from the drum 11 to prevent the first support frame 2 from tilting and detaching from the second support frame 3 under the action of the expanding optical cable on the drum 11. A fixing block 34 is bolted to the winch support 1 near the second support frame 3. An elastic element 35 is fixed between the fixing block 34 and the baffle 32. The elastic element 35 is a large spring. The elastic element 35 pushes the second support frame 3 to move in the groove 13 so that the rotating roller 21 on the first support frame 2 always abuts against the optical cable on the drum 11.

[0034] Reference Figure 1 and Figure 2 A mounting frame 4 is bolted to the end of the winch bracket 1 away from the winding roller. The mounting frame 4 is rotatably connected to the reciprocating screw 41 via bearings. The second drive component 44 is bolted to the outside of the mounting frame 4. The second drive component 44 is a small-power drive motor connected to the power supply. The drive end of the second drive component 44 is fixedly connected to the reciprocating screw 41 via a coupling. A movable frame 42 is mounted on the reciprocating screw 41. The movable frame 42 is rotatably connected to the roller 43 via a rotating shaft. The optical cable is wound around the roller 43 and wound by the drum 11. The second drive component 44 drives the reciprocating screw 41 to rotate, causing the movable frame 42 to move back and forth. This makes the optical cable evenly arranged on the drum 11 when it is wound, reducing the accumulation of the optical cable in some parts of the drum 11 and reducing the possibility of the optical cable slipping off.

[0035] Reference Figure 1 and Figure 2 A mounting hole 421 is provided on the movable frame 42, and a smooth guide rod 45 is inserted into the mounting hole 421. The guide rod 45 is fixedly connected to the mounting frame 4 by bolts. When the movable frame 42 moves back and forth with the reciprocating screw 41, it supports the movable frame 42 and prevents the movable frame 42 from deflecting on the reciprocating screw 41. A groove 431 for receiving the optical cable is provided on the arc surface of the roller 43 to reduce the possibility of the optical cable detaching from the roller 43 when it is received by the roller 43 and moves with the movable frame 42.

[0036] The implementation principle of this application embodiment is as follows:

[0037] In actual operation, the drive unit 12 on the winch support 1 is activated, causing the drum 11 to begin winding the optical cable. The optical cable is received by the roller 43 on the moving frame 42 and moved to the drum 11. The drive unit 44 on the mounting frame 4 drives the reciprocating screw 41 to rotate, causing the moving frame 42 to move back and forth with the optical cable, so that the optical cable is evenly arranged on the drum 11. The support frames 2 on both sides below the drum 11, under the action of the elastic element 24, push the rotating roller 21 on the outside of the rotating shaft 22 to always abut against the optical cable wound on the drum 11. The rotating roller 21 rotates as the drum 11 rotates to wind the optical cable, thus abutting the optical cable on the drum 11. The optical cable is supported to reduce the possibility of it loosening and slipping off. After the support frame 2 moves down and contacts the support frame 2, the expanded optical cable on the drum 11 pushes the rotating roller 21 and the support frame 2 to move along the direction of the slide groove 13. The elastic element 2 35 pushes the support frame 2 3 so that the rotating roller 21 always abuts against the optical cable. When the drum 11 is winding the optical cable, the rotating roller 21 abuts against the optical cable on the drum 11 and rotates with the drum 11 to wind the optical cable, thus supporting the optical cable and reducing the impact on the winding of the optical cable caused by the optical cable being too loosely wound in some positions on the drum 11 and slipping off the drum 11.
