Description

Technical Field

[0001] The invention relates to the technical field of winding equipment, in particular to an automatic winding and unwinding cable drum which can be used multiple times. Background Art

[0002] The cable reel is a reel used to wind cables and is widely used in power construction. The cable reels used in power construction are heavy and the diameter of the cables wound on them is also large. During the cable winding process, the cable reel needs to be placed on a bracket and the cable reel is driven to rotate by a driving device to achieve cable winding.

[0003] In the cable winding method mentioned above, a special cylinder is required to drive the clamping table to reciprocate along the axial direction of the cable drum. In this process, the speed of the motor and the speed of the cylinder need to be considered. The cable winding needs to be coordinated with a special programming program, and manual cooperation is often required to make the winding wire neat, which makes its working method complicated, and the cable is relatively loose during the winding process;

[0004] In summary, when winding the cable, the existing cable reel requires the cooperation of two separate power devices through programming programs to realize the cable winding. The operation method is complicated and the production cost is high. On the other hand, the existing cable reel winding device also has the purpose of axial reciprocating motion along the cable reel by arranging a wire clamping platform on the reciprocating screw and driving the wire clamping platform to rotate on the reciprocating screw through the winding cable of the cable reel. However, the reciprocating screw method has a fixed screw length. During the cable reel winding process, the length of the cable wound on the cable reel varies according to the number of winding layers, and the prior art cannot adjust according to the number of winding turns, resulting in the inability to achieve neat cable winding when the cable is wound to a certain number of layers, and even the cable starts to change turns when it is wound to half a turn.

[0042] The working principle of the automatic winding and unwinding cable drum disclosed in the present invention is as follows: first, the cable drum 4 is fixedly connected to the rotating shaft 3 and the rotating shaft 3 is rotatably connected to the bearing seats 2 on both sides of the frame 1, the cable is passed through the clamping platform 15 and wound on the cable drum 4, and the staff adjusts the distance between the baffles 24 to the required spacing, and starts the motor 5 to drive the rotating shaft 3. The cable drum 4 rotates to wind the wire. During the winding process of the cable drum 4, the pulley 3 29 is driven to rotate by the belt 2 13. The pulley 3 29 drives the connecting rod 1 28 and the gear 3 30 to rotate. The gear 3 30 meshes with the first rotating member 34 and drives the first rotating member 20 to rotate. The first rotating member 20 drives the second rotating member 21 to rotate on the meshing tooth 19. The first rotating member 20 and the second rotating member 21 rotate to make the slider 2 18 step to one side in the slide groove 17. When the slider 2 18 steps to a certain position, the reversing head 40 is engaged with the cavity 1 25 of the baffle 1 24. At this time, the reversing head 40 continues to step. Under the obstruction of the baffle 1 24 and the action of the spring 41, the reversing head 40 reverses to the opposite direction. When reversing, the first swinging member 38 and the second swinging member 39 are in a state of rotation. Under the action of the spring 40, both swing in opposite directions to achieve reversal. The extension member 42 drives the swing triangle member 43 to swing to one side in the cavity 2 70, and the swing latch 45 moves backward by the spacing of the extension tooth 47. The reversing head 40 swings in the opposite direction, causing the sliding meshing member 1 34 hinged by the swing member 37 to disengage from the meshing state and make the sliding meshing member 2 36 mesh with the gear of the second rotating member 21 and drive the second rotating member 21 to rotate. The working mode of the second rotating member 21 and the sliding meshing member 2 36 is the same as the movement mode of the first rotating member 20 and the sliding meshing member 1 34, only the movement direction is opposite. The second rotating member 21 rotates with the first rotating member 20 so that the slider 2 18 is in the slide groove 17 and is aligned with the first rotating member 20 and the second rotating member 21. The slider 18 steps in the direction opposite to the direction of movement. When the slider 18 steps to a certain position, the reversing head 40 engages with the cavity 25 of the baffle 1 24 on the other side. The reversing head 40 continues to step in the opposite direction under the obstruction of the baffle 1 24 and the action of the spring 41. When reversing, the first swinging member 38 and the second swinging member 39 swing in opposite directions under the action of the spring 41 to achieve reversal. The reversing head 40 The swing in the opposite direction drives the hinged sliding meshing member 2 36 out of the meshing state, and makes the sliding meshing member 1 34 mesh with the gear of the first rotating member 20 and drives the first rotating member 20 to rotate. The extension member 42 drives the swing triangle member 43 to swing in the opposite direction in the cavity 2 70, and the swinging latch 45 pushes forward the spacing of an extended tooth 47, so that the rotating disk 46 rotates the spacing of the extended tooth 47. When the cable drum 4 reels a circle of cable, the rotating disk 46 rotates the spacing of the extended tooth 47 to drive the worm 48 and the turbine 49 to rotate through the worm 48. The rotation of the turbine 49 causes the rotating head 55 to drive the swing arm 56 and the outer gear 57 to rotate on the inner gear 53.The outer gear 53 rotates to drive the slider 4 63 to move in the slideway 62. In this process, the slider 3 59, the slideway 62 and the baffle 2 60 move in the first direction along the slideway 2 58 with the movement of the slider 4 63. The clamping platform 15 is arranged at the upper end of the slideway 62 and moves with the movement of the slideway 62 to achieve a stepping distance of a cable width along the axial direction of the cable drum 4. The reciprocating movement realizes the winding of the cable;

[0043] When the cable drum 4 reels one layer, the outer gear 53 moves half a circle inside the inner gear 53, and the cable drum 4 continues to rotate and reel. During the rotation process, the swing arm 56 causes the slider 4 63, the slider 3 59, the slide 62 and the baffle 2 60 to move in the opposite direction of the first direction along the slide groove 2 58, so as to realize the reversal of the cable for reciprocating reeling. During the reversing process, the first slide post 67 on the inner gear 53 engages with the first arc-shaped recess 1 68 on the butterfly rotating member 66 and drives the butterfly rotating member 66 to start rotating. After rotating half a circle, the second slide post 67 behind the butterfly rotating member 68 engages with the arc-shaped recess 2 69 and continues to rotate half a circle before disengaging from the arc-shaped recess 2 69. For each rotation of the butterfly rotating member 68, the baffle 1 24 expands outward by a distance of a cable width, so as to prevent the problem of uneven reeling caused by the change in the reeling length per circle due to the increase in the number of reeling layers.

[0044] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
