Description

Technical Field

[0001] The invention belongs to the technical field of winches, and in particular relates to a winch for communication engineering. Background Art

[0002] When carrying out submarine cable laying projects for marine communication projects, it is necessary to arrange winches on the construction ship, and drop the optical cable onto the seabed, and lay it using diving equipment. However, due to the heavy weight of the optical cable, if the current winches or winches cannot control the release speed of the optical cable when releasing it, the optical cable will fall rapidly due to gravity, which will not only affect the laying work, but the uncontrolled release of the optical cable will pull other equipment on the hull and damage the winch itself, which is not conducive to the laying construction. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a winch for communication engineering, which has better retractable and unretractable effect than the existing winch for optical cables, has higher controllability and higher transmission accuracy, avoids uncontrollable factors, and avoids safety accidents.

[0004] The technical solution adopted by the present invention is as follows: The present invention provides a winch for communication engineering, including a winding drum, a conveying platform and a steady conveying mechanism, wherein the winding drum is arranged on a winding frame, the winding drum is used to wind up and release the optical cable, the conveying platform is arranged on one side of the winding drum, the optical cable is released from the winding drum and transmitted to the conveying platform, and the cable is gradually transported to the seabed through the steady conveying mechanism.

[0005] Furthermore, the steady conveying mechanism comprises a conveying pulley, a locking rod, an adjusting rod, a push-pull rod, a driving rod, a lifting slide rail and a driving frame, and the lifting slide rail is arranged on one side of the conveying platform;

[0006] The conveying pulley is slidably arranged on the conveying platform, the middle end of the locking rod is provided with an adjustment center axis, the locking rod is hingedly arranged in the conveying pulley through the adjustment center axis, one end of the adjustment rod is connected to the adjustment center axis, the other end of the adjustment rod is provided with a pulley, and the adjustment rod is slidably arranged in the lifting slide rail through the pulley; when the adjustment rod rotates, the locking rod is driven to rotate at the same time, and the locking rod can be adjusted to two states by rotating, namely, a state of pressing the optical cable and a state of loosening the optical cable. When the optical cable is pressed, the optical cable can move with the conveying pulley, and when the optical cable is loosened, the optical cable does not move with the conveying pulley;

[0007] One end of the push-pull rod is hinged to the locking rod, the driving rod is hinged to the push-pull rod, the driving rod is rotatably arranged on the driving frame, and the driving rod is driven to rotate by a motor.

[0008] When the driving rod rotates, it drives the push-pull rod to do a push-pull action, and then drives the conveying chute to move through the locking rod.

[0009] In order to control the rotation adjustment of the adjusting rod, the lifting slide rail is arranged to be liftable. When the lifting slide rail rises, it drives the adjusting rod to rotate clockwise, and then drives the locking rod to rotate clockwise to loosen the optical cable. When the lifting slide rail descends, it drives the adjusting rod to rotate counterclockwise, and then drives the locking rod to rotate counterclockwise to tighten the optical cable.

[0010] Furthermore, in order to control the rise of the lifting slide rail, a cam is rotatably provided under the lifting slide rail, and when the cam rotates, the lifting slide rail is lifted up intermittently;

[0011] In order to control the descent of the lifting slide rail, an elastic telescopic support column is connected to the bottom of the lifting slide rail. The elastic telescopic support column has a pulling force to pull the lifting slide rail down.

[0012] Furthermore, the delivery and clamping of the optical cable need to be controlled in association, that is, when the push-pull rod pulls the delivery pulley, the optical cable needs to be clamped, and when the push-pull rod pushes the delivery pulley, the optical cable needs to be loosened;

[0013] Therefore, the rotating shaft end of the driving rod is connected with the linkage wheel 1, the cam is connected with the linkage wheel 2, and the linkage wheel 1 and the linkage wheel 2 are connected by a belt.

[0014] Furthermore, a guide mechanism is provided between the winding drum and the conveying platform, and the guide mechanism includes a guide frame, an upper guide wheel and a lower guide wheel. The upper guide wheel and the lower guide wheel are rotatably provided on the guide frame, and the optical cable passes between the upper guide wheel and the lower guide wheel. The bottom of the guide mechanism is connected to a lifting mechanism, which can control the lifting and moving of the guide mechanism to adjust the guiding position and conveying angle of the optical cable.

[0015] Further, the cam includes a protruding portion and a groove portion.

[0016] In order to further improve the stability of the optical cable transmission, a magnetic powder brake is connected to the reel to provide damping for the reel to avoid over-rotation when the optical cable is released.

[0017] Furthermore, in order to improve the precision of transportation, a transportation groove is provided in the transportation pulley, and transportation grooves are provided on both sides of the transportation platform.

[0018] The beneficial effects achieved by the present invention using the above structure are as follows: This scheme provides a winch for communication engineering, which realizes a step-by-step conveying effect through the setting of a steady conveying mechanism, and controls the stable conveying throughout the entire process, and realizes linkage control of the conveying of the optical cable and the clamping of the optical cable, thereby realizing precise continuous and intermittent conveying effects. At the same time, a magnetic powder brake is set to avoid over-rotation problems, and combined with the restraining effect on the optical cable, the problem of the optical cable suddenly falling out of control can be avoided, thereby avoiding safety hazards. It is more suitable for the transportation of optical cables with larger weight and length, and improves the laying construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figure 1-2 The present invention provides a winch for communication engineering, including a winding drum 1, a conveying platform 2 and a steady conveying mechanism 3, wherein the winding drum 1 is arranged on a winding frame, the winding drum 1 is used for winding and releasing the optical cable, the conveying platform 2 is arranged on one side of the winding drum 1, the optical cable is released from the winding drum 1 and transmitted to the conveying platform 2, and the cable is gradually transported to the seabed through the steady conveying mechanism 3.

[0031] Among them, Figure 3-5 The steady conveying mechanism 3 includes a conveying pulley 4, a locking rod 5, an adjusting rod 6, a push-pull rod 7, a driving rod 8, a lifting rail 9 and a driving frame 10, and the lifting rail 9 is arranged on one side of the conveying platform 2;

[0032] The conveying pulley 4 is slidably arranged on the conveying platform 2, and the middle end of the locking rod 5 is provided with an adjusting middle axis 11, and the locking rod 5 is hingedly arranged in the conveying pulley 4 through the adjusting middle axis 11. One end of the adjusting rod 6 is connected to the adjusting middle axis 11, and the other end of the adjusting rod 6 is provided with a pulley 12, and the adjusting rod 6 is slidably arranged in the lifting slide rail 9 through the pulley 12; when the adjusting rod 6 rotates, the locking rod 5 is driven to rotate at the same time, and the locking rod 5 can be adjusted to two states by rotating, namely, a state of pressing the optical cable and a state of loosening the optical cable. When the optical cable is pressed, the optical cable can move with the conveying pulley 4, and when the optical cable is loosened, the optical cable does not move with the conveying pulley 4;

[0033] One end of the push-pull rod 7 is hinged to the locking rod 5, and the driving rod 8 is hinged to the push-pull rod 7. The driving rod 8 is rotatably arranged on the driving frame 10, and the driving rod 8 is driven to rotate by a motor.

[0034] When the driving rod 8 rotates, it drives the push-pull rod 7 to do a push-pull action, and then drives the conveying chute to move through the locking rod 5.

[0035] In order to control the rotation adjustment of the adjusting rod 6, the lifting slide rail 9 is arranged to be liftable. When the lifting slide rail 9 rises, it drives the adjusting rod 6 to rotate clockwise, and then drives the locking rod 5 to rotate clockwise to loosen the optical cable. When the lifting slide rail 9 descends, it drives the adjusting rod 6 to rotate counterclockwise, and then drives the locking rod 5 to rotate counterclockwise to tighten the optical cable.

[0036] In order to control the rise of the lifting slide rail 9, a cam 13 is rotatably provided under the lifting slide rail 9. When the cam 13 rotates, the lifting slide rail 9 is lifted up intermittently.

[0037] In order to control the descent of the lifting rail 9, an elastic telescopic support column 14 is connected to the bottom of the lifting rail 9. The elastic telescopic support column 14 has a pulling force to pull the lifting rail 9 down.

[0038] The delivery and clamping of the optical cable need to be controlled in association, that is, when the push-pull rod 7 pulls the delivery pulley 4, the optical cable needs to be clamped, and when the push-pull rod 7 pushes the delivery pulley 4, the optical cable needs to be loosened;

[0039] Therefore, the rotating shaft end of the driving rod 8 is connected with a linkage wheel 15 , and the cam 13 is connected with a linkage wheel 2 16 . The linkage wheel 15 and the linkage wheel 2 16 are connected by a belt 17 .

[0040] like Figure 6 A guide mechanism 18 is provided between the winding drum 1 and the conveying platform 2, and the guide mechanism 18 includes a guide frame 19, an upper guide wheel 20 and a lower guide wheel 21. The upper guide wheel 20 and the lower guide wheel 21 are rotatably provided on the guide frame 19, and the optical cable passes between the upper guide wheel 20 and the lower guide wheel 21. The bottom of the guide mechanism 18 is connected to a lifting mechanism 22, which can be a hydraulic cylinder or a lifter to control the lifting and moving of the guide mechanism 18 to adjust the guiding position and conveying angle of the optical cable.

[0041] like Figure 7 The cam 13 includes a protruding portion 23 and a recessed portion 24 .

[0042] In order to further improve the stability of the optical cable, the reel 1 is connected with a magnetic powder brake 25 to provide damping for the reel 1 to avoid over-rotation when the optical cable is released.

[0043] In order to improve the precision of transportation, a transportation groove 26 is provided in the transportation pulley 4, and transportation grooves 26 are provided on both sides of the transportation platform 2.

[0044] During specific use, the cable is first wound onto the winding drum 1. When laying, the cable is first pulled out and passed between the upper guide wheel 20 and the lower guide wheel 21. The guide position and the conveying angle are adjusted by controlling the lifting mechanism 22, and the optical cable is passed through the conveying platform 2 and the conveying pulley 4. When releasing the line, the motor drives the driving rod 8 to rotate, and drives the push-pull rod 7 to do the push-pull action. At the same time, the linkage wheel 1 15 drives the linkage wheel 2 16 to rotate. When the push-pull rod 7 pushes the conveying pulley 4, the cam 13 lifts the lifting slide rail 9, and the lifting slide rail 9 drives the adjusting rod 6 to rotate clockwise, and the locking rod 5 rotates clockwise. At this time, the locking rod 5 releases the optical cable, and the conveying pulley 4 slides on the conveying platform 2 without driving the optical cable to move; when the push-pull rod 7 pulls the conveying pulley 4, the cam 13 does not contact the lifting slide rail 9. At this time, the lifting slide rail 9 is pulled down by the elastic telescopic support column 14, and then the lifting slide rail 9 drives the adjusting rod 6 to rotate counterclockwise, and the locking rod 5 rotates counterclockwise, and then the locking rod 5 presses the optical cable, and the optical cable moves simultaneously with the conveying pulley 4 to produce a conveying effect. The above operation is fully circulated, and the optical cable is continuously and intermittently conveyed. Moreover, due to the effect of the magnetic powder brake 25, a damping effect is automatically generated each time the optical cable is conveyed to prevent the winding drum 1 from over-rotating.
