Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cable winding and unwinding device, in particular to a radar cable winding and unwinding device. BACKGROUND

[0002] Radar is an indispensable device in the information age. During use, power is transmitted through cables. Cables are conductive devices composed of multiple insulated wires, used for transmitting power or signals. Cables are usually stored using devices such as wire spools or wire reels. Wire spools are circular disc-shaped objects used to store cables, while wire reels are devices similar to wheels that can conveniently wind and unwind cables and move. These devices help keep cables neat and facilitate transportation.

[0003] The cable entry end and the spool of the existing cable winding and unwinding device change angles as the amount of cable on the spool changes, causing the cable to wear during winding and unwinding. SUMMARY

[0004] The present application aims to provide a radar cable winding and unwinding device to solve the problem of angle changes between the cable and the entry end when the spool winds and unwinds the cable.

[0005] To achieve the above-mentioned purpose, the specific technical solution of a radar cable winding and unwinding device of the present application is as follows:

[0006] A radar cable winding and unwinding device includes a spool placement device, and two spool placement devices are connected through a transmission device. The spool placement device is arranged on a weight detection device, and a reciprocating movement device is provided on the spool placement device to drive the cable to move back and forth. The weight detection device ensures that the cable is always aligned with the upper end of the spool.

[0007] Further, the spool placement device includes a fixed disc, a rotating shaft, a first rotating ring, a second rotating ring, a rotation limiting device, a limiting device, a limiting release device, and a spool mounting assembly. The fixed disc is arranged on the weight detection device, the rotating shaft is arranged on the fixed disc, the first rotating ring is arranged on the rotating shaft, the second rotating ring is arranged on the first rotating ring, the rotation limiting device is arranged inside the first rotating ring to prevent the rotating shaft and the first rotating ring from rotating relative to each other, the limiting device is arranged inside the first rotating ring to limit the rotation of the limiting device and the fixed disc relative to each other, the limiting release device is arranged on the second rotating ring, the limiting release device presses the limiting device to release the limitation between the first rotating ring and the fixed disc, and the spool mounting assembly is arranged on the rotating shaft for quick spool installation.

[0008] Furthermore, the rotation limiting device includes a first sliding groove, a double-ball-end movable bolt, a first spring, a limiting ball groove, and a receiving groove. The first sliding groove is disposed inside the first rotating ring, the double-ball-end movable bolt slides inside the first sliding groove, the first spring is disposed between the first sliding groove and the double-ball-end movable bolt, the limiting ball groove is disposed on the rotating shaft, and the receiving groove is disposed inside the second rotating ring. When the rotating shaft and the first rotating ring rotate relative to each other, the double-ball-end movable bolt moves into the receiving groove, so that the rotating shaft and the first rotating ring can rotate relative to each other.

[0009] Furthermore, the limiting device includes a second sliding groove, a second spring, a limiting bolt, and a limiting hole. The second sliding groove is disposed inside the first rotating ring, and the limiting bolt slides inside the second sliding groove. A second spring is provided between the limiting bolt and the second sliding groove. The limiting hole is disposed inside the fixed plate. The limiting bolt enters into the limiting hole, thereby restricting and fixing the first rotating ring on the fixed plate. The limiting release device squeezes the limiting bolt to expel the restriction.

[0010] Furthermore, the limit release device includes an arc-shaped groove, a push plate, an arc-shaped spring, and a squeezing inclined fork. The arc-shaped groove is disposed inside the first rotating ring, the push plate is disposed on the second rotating ring and slides inside the arc-shaped groove, an arc-shaped spring is disposed between the arc-shaped groove and the push plate, and the squeezing inclined fork is disposed on the push plate for squeezing the limit bolt.

[0011] Furthermore, the bobbin mounting assembly includes a mounting groove, a limiting inclined plate, a push rod, and a third spring. The mounting groove is disposed on the rotating shaft, the limiting inclined plate slides inside the rotating shaft, the third spring is disposed between the limiting inclined plate and the rotating shaft, and the push rod is disposed on the limiting inclined plate.

[0012] Furthermore, the transmission device connection includes a connecting plate, a transmission shaft, pulleys, and a transmission belt. The transmission shaft is mounted on a fixed plate via the connecting plate, and pulleys are provided at both ends of the transmission shaft. The pulleys drive a second rotating ring via the transmission belt, and the transmission shaft is equipped with a matching servo motor.

[0013] Furthermore, the weight detection device includes a fixed cylinder, a sliding cavity, a detection spring, and a connecting bolt. The fixed cylinder has a sliding cavity inside, the connecting bolt slides inside the sliding cavity, the detection spring is disposed between the connecting bolt and the sliding cavity, and the fixed plate is disposed on the connecting bolt.

[0014] Furthermore, the reciprocating moving device includes a mounting base, a moving groove, a threaded rod, a moving threaded hole block, and a hole plate. The mounting base is mounted on the fixed cylinder via a connecting rod. The moving groove is located inside the mounting base. The threaded rod is located inside the mounting base. The moving threaded hole block slides inside the moving groove. The threaded rod drives the moving threaded hole block to slide inside the moving groove. The hole plate is mounted on the moving threaded hole block. The threaded rod is equipped with a matching servo motor.

[0015] The advantages of this invention are:

[0016] This invention enables the quick installation and removal of spools via a spool placement device. Then, a transmission device connects to drive the spool placement device to take in the cable. During the unloading process, the spool placement device prevents the spool from rotating and causing the cable on the spool to become tangled. The weight detection device ensures that the angle between the cable and the spool remains relatively constant after passing through the repositioning device. The repositioning device ensures that the cable is evenly wound around the spool. Attached Figure Description

Detailed Implementation

[0028] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] like Figures 1-9 As shown, a radar cable winding and unwinding device includes a spool placement device 1, two of which are connected by a transmission device 2. The device is characterized in that the spool placement device 1 is mounted on a weight detection device 3, and the spool placement device 1 is provided with a reciprocating moving device 4 for driving the cable to move back and forth. The weight detection device 3 ensures that the cable is always aligned with the upper end of the spool.

[0031] The spools can be quickly installed and removed using the spool placement device 1. Then, the transmission device 2 drives the spool placement device 1 to take in the cable. When releasing the cable, the spool placement device 1 can prevent the spool from rotating and causing the cable on the spool to become tangled. The weight detection device 3 always ensures that the angle between the cable and the spool after passing through the re-moving device 4 does not change much. The re-moving device 4 makes the cable evenly wound on the spool.

[0032] Among them, such as Figures 1-9 As shown, the bobbin placement device 1 includes a fixed disk 1-1, a rotating shaft 1-2, a first rotating ring 1-3, a second rotating ring 1-4, a rotation limiting device 1-5, a limiting device 1-6, a limiting release device 1-7, and a bobbin mounting assembly 1-8. The fixed disk 1-1 is mounted on the weight detection device 3, the rotating shaft 1-2 is mounted on the fixed disk 1-1, the first rotating ring 1-3 is mounted on the rotating shaft 1-2, the second rotating ring 1-4 is mounted on the first rotating ring 1-3, and the rotation limiting device 1-5, the first rotating ring 1-3, the second rotating ring 1-4, the first rotating ring 1-5, the second rotating ring 1-6, the second rotating ring 1-7, and the second rotating ring 1-8. 5 is set inside the first rotating ring 1-3 to prevent the rotating shaft 1-2 and the first rotating ring 1-3 from rotating relative to each other. The limiting device 1-6 is set inside the first rotating ring 1-3 to limit the rotation of the limiting device 1-6 and the fixed plate 1-1 relative to each other. The limiting release device 1-7 is set on the second rotating ring 1-4. The limiting release device 1-7 squeezes the limiting device 1-6 to release the restriction between the first rotating ring 1-3 and the fixed plate 1-1. The bobbin mounting assembly 1-8 is set on the rotating shaft 1-2 for quick bobbin mounting.

[0033] When releasing the cable, the cable is pulled, and the cable drives the rotating shaft 1-2 to rotate through the spool. However, due to the restriction of the first rotating ring 1-3 by the fixed plate 1-1 through the limiting device 1-6, the first rotating ring 1-3 cannot rotate. When the rotating shaft 1-2 rotates inside the first rotating ring 1-3, the rotation limiting device 1-5 prevents the rotating shaft 1-2 and the first rotating ring 1-3 from rotating relative to each other, so that the rotating shaft 1-2 does not rotate without external force, thus avoiding the cable on the spool from becoming tangled. When retracting the cable, the transmission device 2 drives the second rotating ring 1-4 to rotate. The second rotating ring 1-4 releases the first rotating ring 1-3 by squeezing the limiting device 1-6 through the limiting release device 1-7. The second rotating ring 1-4 drives the first rotating ring 1-3 to rotate through the limiting release device 1-7. The first rotating ring 1-3 drives the rotating shaft 1-2 to rotate through the rotation limiting device 1-5, thereby retracting the cable.

[0034] Among them, such as Figures 1-9As shown, the rotation limiting device 1-5 includes a first sliding groove 1-5-1, a double-ball-end movable bolt 1-5-2, a first spring 1-5-3, a limiting ball groove 1-5-4, and a storage groove 1-5-5. The first sliding groove 1-5-1 is disposed inside the first rotating ring 1-3. The double-ball-end movable bolt 1-5-2 slides inside the first sliding groove 1-5-1. The first spring 1-5-3 is disposed between the first sliding groove 1-5-1 and the double-ball-end movable bolt 1-5-2. The limiting ball groove 1-5-4 is disposed on the rotating shaft 1-2. The storage groove 1-5-5 is disposed inside the second rotating ring 1-4. When the rotating shaft 1-2 and the first rotating ring 1-3 rotate relative to each other, the double-ball-end movable bolt 1-5-2 moves inside the storage groove 1-5-5, so that the rotating shaft 1-2 and the first rotating ring 1-3 can rotate relative to each other.

[0035] During line release, the first spring 1-5-3, through the cooperation of the double-ball end movable bolt 1-5-2 and the limiting ball groove 1-5-4, prevents the rotating shaft 1-2 and the first rotating ring 1-3 from rotating, but allows them to rotate. During line take-up, the take-up groove 1-5-5 and the double-ball end movable bolt 1-5-2 are misaligned, preventing the double-ball end movable bolt 1-5-2 from sliding out of the limiting ball groove 1-5-4, thereby causing the second rotating ring 1-4 to drive the rotating shaft 1-2 to rotate through the first rotating ring 1-3.

[0036] Among them, such as Figures 1-9 As shown, the limiting device 1-6 includes a second sliding groove 1-6-1, a second spring 1-6-2, a limiting bolt 1-6-3, and a limiting hole 1-6-4. The second sliding groove 1-6-1 is disposed inside the first rotating ring 1-3. The limiting bolt 1-6-3 slides inside the second sliding groove 1-6-1. The second spring 1-6-2 is disposed between the limiting bolt 1-6-3 and the second sliding groove 1-6-1. The limiting hole 1-6-4 is disposed inside the fixed plate 1-1. The limiting bolt 1-6-3 enters the limiting hole 1-6-4, thereby restricting and fixing the first rotating ring 1-3 on the fixed plate 1-1. The limiting release device 1-7 squeezes the limiting bolt 1-6-3 to expel the restriction.

[0037] Among them, such as Figures 1-9 As shown, the limit release device 1-7 includes an arc-shaped groove 1-7-1, a push plate 1-7-2, an arc-shaped spring 1-7-3, and a pressing inclined fork 1-7-4. The arc-shaped groove 1-7-1 is disposed inside the first rotating ring 1-3. The push plate 1-7-2 is disposed on the second rotating ring 1-4 and slides inside the arc-shaped groove 1-7-1. The arc-shaped spring 1-7-3 is disposed between the arc-shaped groove 1-7-1 and the push plate 1-7-2. The pressing inclined fork 1-7-4 is disposed on the push plate 1-7-2 for pressing the limit bolt 1-6-3.

[0038] Among them, such as Figures 1-9As shown, the bobbin mounting assembly 1-8 includes a mounting groove 1-8-1, a limiting inclined plate 1-8-2, a push rod 1-8-3, and a third spring 1-8-4. The mounting groove 1-8-1 is disposed on the rotating shaft 1-2, the limiting inclined plate 1-8-2 slides inside the rotating shaft 1-2, the third spring 1-8-4 is disposed between the limiting inclined plate 1-8-2 and the rotating shaft 1-2, and the push rod 1-8-3 is disposed on the limiting inclined plate 1-8-2.

[0039] Among them, such as Figures 1-9 As shown, the transmission device connection 2 includes a connecting plate 2-1, a transmission shaft 2-2, a pulley 2-3, and a transmission belt 2-4. The transmission shaft 2-2 is mounted on the fixed disk 1-1 via the connecting plate 2-1. The transmission shaft 2-2 has pulleys 2-3 at both ends. The pulleys 2-3 drive the second rotating ring 1-4 via the transmission belt 2-4. The transmission shaft 2-2 is equipped with a matching servo motor.

[0040] Among them, such as Figures 1-9 As shown, the weight detection device 3 includes a fixed cylinder 3-1, a sliding cavity 3-2, a detection spring 3-3, and a connecting bolt 3-4. The fixed cylinder 3-1 has a sliding cavity 3-2 inside, the connecting bolt 3-4 slides inside the sliding cavity 3-2, the detection spring 3-3 is disposed between the connecting bolt 3-4 and the sliding cavity 3-2, and the fixed plate 1-1 is disposed on the connecting bolt 3-4.

[0041] When the cable on the spool changes position, the detection spring 3-3 will change the position of the spool through the connecting bolt 3-4.

[0042] Among them, such as Figures 1-9 As shown, the reciprocating moving device 4 includes a mounting base 4-1, a moving groove 4-2, a threaded rod 4-3, a moving threaded hole block 4-4, and a hole plate 4-5. The mounting base 4-1 is mounted on the fixed cylinder 3-1 via a connecting rod. The moving groove 4-2 is located inside the mounting base 4-1. The threaded rod 4-3 is located inside the mounting base 4-1. The moving threaded hole block 4-4 slides inside the moving groove 4-2.

The threaded rod 4-3 is equipped with a matching servo motor.

[0043] The motor drives the movable threaded hole block 4-4 and the hole plate 4-5 to move via the threaded rod 4-3, thereby causing the cable to be wound on the spool.
