Description

Technical Field

[0001] This invention belongs to the field of mechanics, and in particular relates to a large-angle integrated coaxial bending device. Background Technology

[0002] In fields such as military radar, communication navigation, satellite communication, and precision instruments, bus rings are generally used to achieve continuous transmission of electricity and signals between stationary and rotating equipment. During operation, the bus ring primarily relies on the sliding contact between the brushes and conductive rings between the stator and rotor to transmit power while the rotor is continuously rotating. However, in applications involving high power transmission and discontinuous rotation, bus rings suffer from drawbacks such as complex design, large size and weight, low reliability, and stringent maintenance requirements.

[0003] Patent CN201510205486.7, invention title: A high-power rolling bus ring device. This patent transmits electrical signals and power through the rolling contact between the conductive ring and the rolling block and the rolling block and the flexible ring. It has low wear and long life, but its composition is complex, its size is large and its weight is heavy, and it is not suitable for low-cost and space-constrained structures.

[0004] Patent CN201621149542.6, invention title: A cable rotation installation device inside an antenna mount, provides a cable rotation installation device inside an antenna mount that can eliminate the bending phenomenon when multiple cables or optical cables are rotated for transmission. However, the cable is rigidly fixed at both ends of the turntable and the antenna mount, and the lifting ring restricts the cable rotation, which can easily cause cable damage. It is not suitable for large-angle bending of high-power thick cables.

[0005] Therefore, there is an urgent need to design an installation device that can reliably transmit electrical energy and hydraulic pressure to various pipelines such as high-power power supplies, optical cables, oil pipes, and water pipes in a discontinuous rotation state within a limited space. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, this invention proposes a comprehensive coaxial bending device for high-power cables, optical cables, oil pipes, and water pipes. This device solves the problems of complex structure, large size, high cost, and complicated maintenance of current high-power bus rings, enabling large-angle coaxial bending of multiple high-power cables in a small space, thus meeting the requirements for low-cost, maintenance-free large-angle bending.

[0007] The large-angle integrated winding device proposed in this invention includes multiple cable clamps 1, a moving ring bracket 2, a moving ring 3, a stationary ring 4, a stationary ring bracket 5, a base 15, and a turntable 16. The moving ring 3 and stationary ring 4 each include a moving ring cable clamp fixing frame 13 and a stationary ring cable clamp fixing frame 14, respectively. The moving ring 3 is mounted on the turntable 16 via the moving ring bracket 2, and the stationary ring 4 is mounted on the base 15 via the stationary ring bracket 5. The cable clamps 1 are respectively mounted on the corresponding moving ring cable clamp fixing frames 13 and stationary ring cable clamp fixing frames 14. The cable first passes through the cable clamp 1 of the stationary ring 4 from the base 15, winds into a U-shape, and then passes through the cable clamp 1 of the moving ring 3. The cable is bundled and fixed by the cable clamp 1. When the turntable 16 rotates, it drives the moving ring 3 to rotate, and the cable clamp 1 rotates under the influence of the cable, thus achieving a large-angle rotation of the turntable 16.

[0008] Furthermore, the cable clamp 1 includes a cable clamp frame 8, a cable clamp rotating frame 7, and a connecting screw 12; when the cable clamp rotating frame 7 is opened, multiple cables are placed into the cable clamp frame 8, and when the cable clamp rotating frame 7 is closed, the cables are secured. The cable clamp 1 is connected to the moving ring cable clamp fixing frame 13 and the stationary ring cable clamp fixing frame 14 through the connecting screw 12.

[0009] Furthermore, the cable clamp 1 can rotate around the connecting screw 12 and swing left and right to accommodate the cable swinging when the turntable 16 rotates, thus releasing stress.

[0010] Furthermore, the cable clamp 1 also includes a cable bushing 9 and a cable divider block 10; the cable bushing 9 is inserted into the cable clamp frame 8 along the slot, the inner side of the cable is in contact with the cable bushing 9, and multiple cables are divided into sections by the cable divider block 10.

[0011] Furthermore, the cable clamp 1 also includes a fastening bolt 6 and a cable pressing block 11; the cable pressing block 11 and the fastening bolt 6 are both connected to the cable clamp rotating frame 7, and the cable pressing block 11 is connected to the fastening bolt 6 on the outside. The cable pressing block 11 is controlled to press the cable by adjusting the fastening bolt 6.

[0012] Furthermore, the moving ring 3 is a split type, consisting of three identical moving ring cable clamp fixing frames 13, which are spliced ​​together by bolts to form a complete moving ring 3.

[0013] Furthermore, the stationary ring 4 is a split type, consisting of three identical stationary ring cable clamp fixing frames 14, which are spliced ​​together by bolts to form a complete stationary ring 4.

[0014] Furthermore, it also includes a coaxial drum 18, and when the turntable 16 rotates at a large angle, the cable is in contact with the coaxial drum 18.

[0015] Furthermore, a water hinge or an oil hinge can be arranged in the space between the moving ring 3 and the stationary ring 4.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. Small space occupation: The space for cable routing and winding is small, and there is no need for structures such as stator, rotor and carbon brush. Water hinges can also be arranged in the middle, resulting in high space utilization.

[0018] 2. High transmission power: The cables are arranged in separate rows, allowing for the placement of multiple high-power cables;

[0019] 3. Multi-pipeline integrated transmission: It can integrate cables, optical cables, water pipes and oil pipes to realize the transmission of electrical energy, optical fiber and hydraulic pressure;

Detailed Implementation

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0028] like Figure 1 As shown, a large-angle integrated winding device of the present invention includes a cable clamp 1, a moving ring bracket 2, a moving ring 3, a stationary ring 4, and a stationary ring bracket 5. Figure 1 The image shows a winding device without cables, oil pipes, or water pipes installed. Figure 5 The image shows a cable winding device.

[0029] like Figure 2 As shown, the cable clamp 1 includes a cable clamp frame 8, a cable clamp rotating frame 7, a fastening bolt 6, a cable bushing 9, a cable separator block 10, a cable pressing block 11, and a connecting screw 12. When the cable clamp rotating frame 7 is opened, the cable bushing 9 is inserted into the cable clamp frame 8 along the slot. Two cables are placed inside the cable clamp frame 8, with the inner cable fitting against the cable bushing 9. The two cables are divided in the middle by the cable separator block 10. When the rotating frame 7 is closed, the cable pressing block 11 is connected to the outer fastening bolt 6. The cable pressing block 11 is adjusted to press the cables by the fastening bolt 6. The cable clamp 1 is connected and fixed to the rotating cable clamp fixing frame 13 and the stationary cable clamp fixing frame 14 through the connecting screw 12. The cable clamp 1 can rotate around the connecting screw 12.

[0030] like Figure 3 As shown, the moving ring 3 consists of three identical moving ring cable clamp fixing brackets 13, which are connected by bolts to form a complete moving ring 3.

[0031] like Figure 4 As shown, the stationary ring 4 consists of three identical stationary ring cable clamp brackets 14, which are connected by bolts to form a complete stationary ring 4.

[0032] The rotating ring 3 of the winding device is mounted on the turntable 16 via the rotating ring bracket 2, and the stationary ring 4 is mounted on the base 15 via the stationary ring bracket 5. The cable clamp 1 is mounted on the corresponding rotating ring cable clamp fixing bracket 13 and stationary ring cable clamp fixing bracket 14 via the connecting screw 12. The cable first passes through the cable clamp 1 of the stationary ring 4 from the base 15, is wound into a U-shape, and then passes through the cable clamp 1 of the rotating ring 3. The cables passing through the rotating ring cable clamp 1 and the stationary ring cable clamp 1 are fixed by the fastening bolt 6.

[0033] Example:

[0034] The installation method of a radar cable, oil pipe, water pipe, and optical cable via a large-angle integrated winding device from the base 15 to the turntable 16 is discussed as an example.

[0035] 1) The installation diagram of cables, oil pipes, water pipes, and optical cables on the turntable 16 on the base 15 is as follows: Figure 5 As shown.

[0036] 2) The moving ring 3 and the stationary ring 4 are assembled into a whole by separate parts, which can be installed in a small space.

[0037] 3) The cable clamp 1, which fixes cables, oil pipes, water pipes, etc., sets the clamping amount of cables, oil pipes, and water pipes through the bushing 9, the partition block 10 and the cable clamping block 11, to ensure that the cables, oil pipes and water pipes are clamped without damaging them.

[0038] 4) When the turntable 16 rotates, it drives the rotating ring 3 to rotate. The cable clamp 1 rotates around the connecting screw under the drive of the cable, realizing the large-angle rotation of the turntable 16. When the turntable 16 rotates at a large angle, the cable, oil pipe and water pipe are in contact with the coaxial barrel 18. The coaxial barrel 18 is made of a low friction coefficient material to avoid wear and entanglement of the cable, oil pipe and water pipe.

[0039] 5) Cables, oil pipes, water pipes, optical cables, etc. are wound into a U-shape to enable the turntable 16 to drive the moving ring 3 to bend at a large angle. The space between the moving ring 3 and the stationary ring 4 can be used to arrange devices such as water hinges 17 and oil hinges.

[0040] This invention is not limited to the specific embodiments described above, and various modifications and variations are possible.
