Description

Technical Field

[0002] Conductive slip rings are electrical components responsible for transmitting energy and signals to rotating bodies. According to the transmission medium, slip rings are divided into conductive slip rings, fluid slip rings and smooth rings. It can also be commonly referred to as "rotary communication" or "rotary communication". Slip rings are usually installed at the rotating center of the equipment, which is mainly composed of rotating parts and stationary parts. The rotating part is connected to the rotating structure of the equipment and rotates with it, called the "rotor", while the stationary part is connected to the energy source of the fixed structure of the equipment, called the "stator". The slip ring as a whole relies on the elastic grinding principle, rolling grinding principle or sealing principle, as well as the ingenious design of the motion structure and sealing structure, the precise matching of parts manufacturing and the reasonable material selection. Form a stable and reliable rotary communication system. As long as the slip ring is attached to the infinite rotating device, it can provide power and energy to the rotating body, so that the rotating body can perform other movements or detect the working status under the rotating state while moving infinitely. The cable is mainly used to control installation, connect equipment, transmit electricity, etc. After production, the cable needs to be wound in a cylindrical shape by a winding device for storage, transportation and sale. In the process of communication engineering construction, different types of cables are needed to connect communication lines. After use, the cables need to be recycled and reused. Usually, a cable winding device is used to wind them up for easy storage and transportation.

[0003] In most existing cable winding devices, the size of the winding roller is fixed, and the diameter of the winding roller cannot be adjusted accordingly as needed. This results in that when winding a shorter cable, if a winding roller with a smaller diameter is used, the number of turns of the winding roller needs to be increased, which will lead to low cable winding efficiency. Summary of the invention

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a conductive slip ring and a cable retracting device using the conductive slip ring, which has the following beneficial effects:

[0019] 1. The conductive slip ring and the cable retracting and releasing device using the conductive slip ring are fixed by the first electromagnet due to its own magnetic force and the fourth connecting gear. Then the servo motor is started. When the output end of the servo motor drives the insulating rod to rotate, it will drive the first electromagnet to rotate synchronously, and then synchronously drive the fourth connecting gear to rotate on the surface of the insulating block. When the fourth connecting gear rotates, it meshes with the third connecting gear, driving the third connecting gear to drive the rotating rod to rotate synchronously. When the rotating rod rotates, it drives the second connecting gear to rotate synchronously. When the second connecting gear rotates, it meshes with the first connecting gear, so that the first connecting gear rotates on the surface of the support plate.

The continuous rotation of the first connecting gear controls the outward expansion distance of the supporting piece, so that the distance between them can be changed as needed to solve the problem that when a shorter cable is wound up, if a smaller diameter winding roller is used, the number of turns of the winding roller needs to be increased, which will lead to low cable winding efficiency and improve the overall practicality.

[0020] 2. The conductive slip ring and the cable retracting and releasing device using the conductive slip ring drive the second pulley to rotate synchronously due to the transmission belt through the first pulley, and the second pulley will drive the driving member to rotate synchronously when rotating, so that the driving member drives the first bevel gear to rotate synchronously when rotating, and the first bevel gear and the second bevel gear are meshed and transmitted, so that when the first bevel gear drives the second bevel gear to rotate, it drives the driving shaft to rotate synchronously, and the driving shaft drives the rotating disk to rotate. When the matching piece on the surface of the rotating disk rotates, it slides in the groove inside the moving block. Since the matching block fixedly connected to one side of the moving block is connected to the slide rail, the matching piece drives the moving block to rotate synchronously. When moving, it will only reciprocate left and right, so that the matching block drives the matching ring to move left and right through the matching rod, so that when the cable is wound, it will be driven by the matching ring to move left and right, so that the cable can reciprocate when it is wound, thereby preventing the cables from being entangled and making it inconvenient to release the cables. At the same time, the length detection sensor set up will monitor the length of the cable released, which is convenient for the staff to calculate. At the same time, the support frame is set up, and the support frame is rotated inside the moving frame through the moving roller below, which can facilitate the staff to move the entire device, making the entire device more convenient to carry.

[0033] For alternative specific embodiment 2, please refer to Figure 1-7 The staff can replace the third connecting gear 213 and the fourth connecting gear 216 according to the actual usage. They can be replaced with two sets of transmission wheels, and the two sets of transmission wheels can be transmitted through a transmission belt. The specific assembly parts only need to be able to play a transmission role, so that the rotating rod 208 can rotate synchronously, and can be magnetically adsorbed and fixed with the first electromagnet 215.

[0034] Working principle: The staff can start the first electromagnet 215 according to the specific length of the cable. The first electromagnet 215 and the second electromagnet 218 are arranged opposite to each other. When the first electromagnet 215 is started, the second electromagnet 218 will automatically close. The first electromagnet 215 is adsorbed and fixed to the fourth connecting gear 216 due to its own magnetic force. Then the staff sends an electrical signal to the conductive slip ring through the device. The conductive slip ring drives the output end of the servo motor 31 to drive the insulating rod 217 to rotate through the electrical signal, which will drive the first electromagnet 215 to rotate synchronously, and then synchronously drive the fourth connecting gear 216 to rotate on the surface of the insulating block 214. When the fourth connecting gear 216 rotates, it meshes with the third connecting gear 213, driving the third connecting gear 213 to drive The rotating rod 208 rotates synchronously, and the rotating rod 208 drives the second connecting gear 209 to rotate synchronously when rotating. When the second connecting gear 209 rotates, it meshes with the first connecting gear 206, so that the first connecting gear 206 rotates on the surface of the support plate 201. At the same time, when the first connecting gear 206 rotates, the sliding groove arranged on its surface will push the connecting piece 207 on the surface of the support block 203 to slide outward or inward, thereby driving the support block 203 to move through the sliding groove 202 through the connecting piece 207. At the same time, when the support block 203 moves, it will drive the connecting plate 204 to move synchronously. When the connecting plate 204 moves inward synchronously, it will squeeze the supporting spring 212 on the surface of the reset rod 211. When the connecting plate 204 moves outward, the supporting spring 212 The contraction of elastic potential energy will form a reverse thrust force to push the connecting plate 204 outward. During this process, part of the surface of the reset rod 211 is always slidably connected to the inside of the support member 205, and the first connecting gear 206 continues to rotate, thereby controlling the outward expansion distance of the support member 205. After rotating to the appropriate position, the staff can pass one end of the cable through the matching ring 44 and fix it to the surface of the support member 205 on one side. Then the staff will start the second electromagnet 218 on the other side, and the corresponding first electromagnet 215 will automatically close. Then the staff will start the first electromagnet 215 and start the servo motor 31 on one side at the same time. When the output end of the servo motor 31 drives the insulating rod 217 to rotate, the insulating rod 217 The second electromagnet 218 is driven to rotate, and the second electromagnet 218 rotates on the surface of the first electromagnet 215. At the same time, the second electromagnet 218 is adsorbed and fixed to the connecting tube 219 due to magnetic attraction, thereby driving the connecting tube 219 to drive the support plate 201 to rotate, so as to reel the cable. At the same time, when the insulating rod 217 on one side rotates, it will drive the first pulley 33 on its surface to rotate synchronously. The first pulley 33 drives the second pulley 34 to rotate synchronously due to the transmission belt. When the second pulley 34 rotates, it will drive the driving member 50 to rotate synchronously, so that when the driving member 50 rotates, it drives the first bevel gear 51 to rotate synchronously. The first bevel gear 51 and the second bevel gear 52 are meshed for transmission, so that when the first bevel gear 51 drives the second bevel gear 52 to rotate,The driving shaft 46 is driven to rotate synchronously, and the driving shaft 46 drives the rotating disk 47 to rotate. When the matching piece 48 on the surface of the rotating disk 47 rotates, it will slide in the groove inside the moving block 49. Since the matching block 42 fixedly connected to one side of the moving block 49 is slidably connected to the slide rail 41, the matching piece 48 will only reciprocate left and right when driving the moving block 49 to move, so that the matching block 42 drives the matching ring 44 to move left and right through the matching rod 43, so that when the cable is wound, it will be driven by the matching ring 44 to move left and right. When the winding is completed, the staff starts the second electromagnet 218 on the other side, and the effect is the same as above. When the cable needs to be released, it is only necessary to start the output ends of the servo motors 31 on both sides to rotate synchronously. The output ends of the servo motors 31 drive the second electromagnet 218 on the surface of the insulating rod 217 to rotate synchronously on the surface of the first electromagnet 215. The second electromagnet 218 is magnetically adsorbed and fixed to the connecting tube 219, thereby realizing the release of the cable. When the cable is released, the length detection sensor will monitor the length of the cable released, which is convenient for the staff to calculate. At the same time, the staff can push the support frame 1, and the support frame 1 rotates inside the moving frame 6 through the moving roller 7 below, which is convenient for the staff to move the entire device.

[0035] In summary, the conductive slip ring and the cable retracting and releasing device using the conductive slip ring are fixed by the first electromagnet 215 and the fourth connecting gear 216 due to its own magnetic force, and then the servo motor 31 is started. When the output end of the servo motor 31 drives the insulating rod 217 to rotate, it will drive the first electromagnet 215 to rotate synchronously, and then synchronously drive the fourth connecting gear 216 to rotate on the surface of the insulating block 214. When the fourth connecting gear 216 rotates, it meshes with the third connecting gear 213, driving the third connecting gear 213 to drive the rotating rod 208 to rotate synchronously. When the rotating rod 208 rotates, it drives the second connecting gear 209 to rotate synchronously. When the second connecting gear 209 rotates, it meshes with the first connecting gear 206, so that the first connecting gear 206 is on the support plate. 201 surface rotates, and at the same time, when the first connecting gear 206 rotates, the sliding groove arranged on its surface will push the connecting piece 207 on the surface of the supporting block 203 to slide outward or inward, thereby driving the supporting block 203 to move through the sliding groove 202 through the connecting piece 207. At the same time, when the supporting block 203 moves, it will drive the connecting plate 204 to move synchronously. When the connecting plate 204 moves inward synchronously, it will squeeze the supporting spring 212 on the surface of the reset rod 211. When the connecting plate 204 moves outward, the supporting spring 212 will form a reverse thrust force due to the contraction of elastic potential energy, pushing the connecting plate 204 outward. In this process, part of the surface of the reset rod 211 is always slidably connected to the inside of the supporting piece 205, and the continuous rotation of the first connecting gear 206 causes the connecting plate 204 to move outward. The outward expansion distance of the support member 205 is controlled so that the distance between them can be changed as needed to solve the problem that when a shorter cable is wound up, if a winding roller with a smaller diameter is used, the number of turns of the winding roller needs to be increased, which will lead to low cable winding efficiency. The overall practicality is improved. The first pulley 33 drives the second pulley 34 to rotate synchronously due to the transmission belt. When the second pulley 34 rotates, it will drive the driving member 50 to rotate synchronously, so that when the driving member 50 rotates, it drives the first bevel gear 51 to rotate synchronously. The first bevel gear 51 and the second bevel gear 52 are meshed for transmission, so that when the first bevel gear 51 drives the second bevel gear 52 to rotate, it drives the drive shaft 46 to rotate synchronously, and the drive shaft 46 drives the rotating The movable disk 47 rotates, and the matching piece 48 on the surface of the rotating disk 47 slides in the groove inside the moving block 49 when it rotates. Since the matching block 42 fixedly connected to one side of the moving block 49 is connected to the slide rail 41, the matching piece 48 will only reciprocate left and right when driving the moving block 49 to move, so that the matching block 42 drives the matching ring 44 to move left and right through the matching rod 43, so that when the cable is wound, it will be driven by the matching ring 44 to move left and right, so that when the cable is wound, it can reciprocate, thereby preventing the problem of cables being entangled and inconvenient to release the cable. At the same time, the length detection sensor set up will monitor the length of the cable released, which is convenient for the staff to calculate, and at the same time, through the support frame 1 set up,The support frame 1 rotates inside the moving frame 6 through the moving roller 7 below, which makes it easier for the staff to move the entire device, making the entire device more portable.
