Description

Technical Field

[0001] This invention belongs to the field of cable production technology, and in particular relates to a cable winding and unwinding device. Background Technology

[0002] With economic development, the use of cables is indispensable in urban construction, and the cable industry has also developed rapidly. Cables, which are mainly used for transmitting and distributing electrical energy, are commonly used in urban underground power grids and internal power supply for enterprises. During power construction, various types of cables need to be laid using cable laying equipment. In particular, when laying power cables in the direction of high-voltage transmission, it is necessary to lay various types of cables.

[0003] The function of cable winding and unwinding devices is to wind cables onto reels after production or to release them during construction. Reels are typically made of steel or aluminum, and their size and capacity depend on the length and diameter of the cable. However, existing cable reels present numerous inconveniences in both unwinding and winding. Because the cable winding and unwinding devices consist of only simple take-up rollers combined with manual operation, this method of unwinding and winding is extremely inefficient and has significant limitations. Furthermore, existing reels come in various diameters, often requiring the use of winding and unwinding devices of different diameters to complete the operations, resulting in wasted resources.

[0076] The sliding base 3 includes a sliding base plate, on which a servo slide with a support plate is mounted. The support frame is mounted on the support plate of the servo slide. The servo slide is driven by a servo motor, which is programmed and controlled by a controller. The controller controls the feed rate of the servo slide according to the size of the reel.

[0077] In this embodiment, the side fixing plate 1 is fixedly installed and used to support and reinforce the support frame. The support frame is used to place the reel, and the support base is used to support the reel and lift it upward. Under the drive of the sliding base 3, the support frame moves closer to or further away from the side fixing plate 1, thereby supporting the reel lifted by the support base or loosening the reel stuck between the side fixing plate 1 and the diameter of the support frame, so as to facilitate the placement and removal of the reel. This improves the operability of the take-up and unload device and makes it simple to operate. The loading and unloading of the reel can be achieved by cooperating with the reel handling machinery. Moreover, the distance between the support frame and the diameter of the side fixing plate 1 can be adjusted under the drive of the sliding base 3, thereby ensuring the placement of reels of different sizes and capacities.

[0085] In this embodiment, the support base plate 4 facilitates the connection between the support seat and the fixed seat 100; the electric push rod 5, controlled by the controller, drives the support base plate 4 to move up and down, thereby lifting or lowering the reel placed on the support seat. If a telescopic guide rod is provided to support the support base plate 4, the stability of the up and down movement of the support base plate 4 can be further improved; the reel support mechanism is used to place and support the reel to prevent it from loosening before it is fixed by the support frame; the slot of the arc plate 8 in the reel support mechanism can hold the edge of the reel, thereby preventing the reel from loosening; the cooperation of the slider and guide rail in the reel support mechanism drives the gap of the arc plate 8 on the two support plates 7 to adjust, thereby facilitating the placement of reels of different lengths; the arc plate 8 is fixed in a detachable manner, thereby facilitating the placement of reels of different diameters; and the coupling 9 facilitates the operation of the two structures with one motor.

[0100] A telescopic connector is provided in the middle of the rotating support rod 16;

[0101] An intermediate limiting member is provided in the middle of the rotating support rod 16, surrounding the telescopic connector.

[0103] Example 5:

[0104] This embodiment provides a cable winding and unwinding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0105] The fasteners include:

[0106] Rotary connecting seat 13 is mounted on the side fixing plate 1;

[0110] Example 6:

[0111] This embodiment provides a cable winding and unwinding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0112] The telescopic connector includes:

[0113] The outer connecting cylinder 17 has a compression chamber inside, and one end of the connecting cylinder is an open end and the other end is a closed end, and a through hole is provided on the closed end;

[0114] An end-sealing plug is provided on the closed end of the outer connecting cylinder 17, and the end-sealing plug is provided with a through hole.

[0115] An intermediate compression component is provided inside the compression chamber;

[0116] The intermediate compression component includes end connecting plates 18 disposed on both sides of the compression chamber, and a plurality of coaxially arranged compression springs 19 are disposed between the two end connecting plates 18. The end connecting plates 18 are stepped, and the rotating support rod 16 has a two-section structure including a first shaft portion 16a and a second shaft portion 16b. One end of the first shaft portion 16a is rotatably connected to the upper fixed plate 11, and the first support 12 is fixedly connected to the side of the first shaft portion 16a near the upper fixed plate 11. The other end of the first shaft portion 16a passes through a through hole into the outer connecting cylinder 17 and is slidably connected to the end connecting plate 18 on one side of the compression chamber. A support spring 33 is provided between the first shaft portion 16a and the outer connecting cylinder 17, and a stop is formed at the end of the first shaft portion 16a to prevent the end connecting plate 18 from falling off; one end of the second shaft portion 16b passes through the through hole into the outer connecting cylinder 17 and is fixedly connected to the end connecting plate 18 on the other side of the compression chamber; wherein the through hole, the through hole and the cross section of the compression chamber are all regular polygons, and the ends of the first shaft portion 16a and the second shaft portion 16b extending into the outer connecting cylinder 17 are regular polygons, and the first shaft portion 16a and the second shaft portion 16b are respectively fixedly connected to the end connecting plate 18 at their respective ends, and the cross section of the side with the largest diameter of the end connecting plate 18 is a regular polygon that matches the inside of the compression chamber.

[0117] In this embodiment, the outer connecting cylinder 17 is used to connect and limit the first shaft portion 16a and the second shaft portion 16b. The end connecting plate 18 inside the outer limiting cylinder 34 achieves the effect of limiting the first shaft portion 16a and the second shaft portion 16b. At the same time, the cross-sections of the through hole, the through hole, and the compression cavity are all regular polygons, and the ends of the first shaft portion 16a and the second shaft portion 16b extending into the outer connecting cylinder 17 are also regular polygons. The first shaft portion 16a is adapted to the through hole, and the second shaft portion 16b is adapted to the through hole, thereby better achieving torque. The transmission; the cooperation of the compression spring 19 and the end connecting plate 18, by squeezing one end of the second shaft 16b, compresses the second shaft 16b, causing the compression spring 19 to be compressed. At the same time, the compression spring 19 drives the end connecting plate 18 on the first shaft 16a to compress away from the second shaft 16b, and at the same time compresses the support spring 33, causing the first shaft 16a and the second shaft 16b to slide into the outer connecting cylinder 17, so as to compress the length of the rotating support shaft, thereby achieving the effect of fixing reels of different lengths.

[0118] Example 7:

[0119] This embodiment provides a cable winding and unwinding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0120] The intermediate limiting component includes:

[0121] Side limiting blocks 20, two side limiting blocks 20 are symmetrically arranged on both sides of the telescopic connector, one side limiting block 20 is sleeved on the first shaft portion 16a, and the other side limiting block 20 is sleeved on the second shaft portion 16b, and the second shaft portion 16b has an abutting edge that abuts against the side of the side limiting block 20 near the middle compression member.

[0122] External clamping blocks 21, a plurality of external clamping blocks 21 are evenly distributed around the circumference and are arranged between two side limiting blocks 20;

[0123] Side support rod 23, each outer clamping block 21 has a side support rod 23 extending to the side limiting blocks 20 on both sides, and the two ends of the side support rod 23 are rotatably connected to the side limiting block 20 and the outer clamping block 21 respectively.

[0124] Side floating springs are provided on both sides of the telescopic connector, with one side floating spring sleeved on the first shaft 16a and the other side floating spring sleeved on the second shaft 16b, and the other end of the side floating spring abutting against the side connecting block on the same side.

[0125] The side limiting block 20 has an arc-shaped abutment on its outer side, and the outer clamping block 21 has a through clamping shaft.

The outer edge of the side limiting block 20 is provided with a side fixing block, and the side support rod 23 is rotatably connected to the side limiting block 20 through the side fixing block.

[0126] In this embodiment, the side limiting block 20 is used to support the intermediate limiting member, and the side support blocks 27 on both sides of each outer clamping block 21 are V-shaped closed. When the distance between the two side limiting blocks 20 changes, the included angle of the two side support rods 23 changes, which changes the distribution diameter of the several cylindrical outer clamping blocks 21. When the diameter increases, it can abut against the inner wall of the reel, thereby achieving the effect of clamping and reinforcing the reel. The abutment of the outer clamping block 21 will not rotate towards the outer connecting cylinder 17 when it is limited by the side support rod 23. Regardless of the abutment's position, after the side limiting block 20 contacts the inner wall of the reel, it continues to expand outward. The abutment and the side limiting block 20 are in a stable state, which will cause the abutment to rotate towards the inner wall of the reel, thereby firmly adhering to the inner wall of the reel and achieving a good fixing effect.
