Description

Technical Field

[0001] The invention relates to the technical field of conductive slip ring brackets, in particular to a spliced ​​bracket of a conductive slip ring. Background Art

[0002] Conductive slip ring is an electrical component, its function is to provide energy and signal transmission for rotating body. According to the different transmission media, conductive slip ring can be divided into conductive slip ring, fluid slip ring and smooth ring. Conductive slip ring is generally installed at the rotation center of the equipment, and consists of two parts: rotor and stator.

[0003] Publication No.: CN115332901A discloses a spliced ​​bracket of a conductive slip ring, comprising a large-end bearing seat, a small-end bearing seat and a connecting rod, wherein the two ends of the connecting rod are detachably connected to the large-end bearing seat and the small-end bearing seat, respectively, and there are multiple connecting rods, and the multiple connecting rod arrays are arranged between the large-end bearing seat and the small-end bearing seat. The device solves the problem of poor applicability of the bracket of the conductive slip ring. In actual use, since the rotor output line of the conductive slip ring needs to be connected to the power supply end, users generally stick the longer rotor output line to the surface of the slip ring stator or directly suspend it during use. The sticking method for handling the longer rotor output line is likely to cause problems with the subsequent conductive slip ring, which is difficult to separate from the power supply end when it needs to be disassembled. The suspension method is more dangerous and the rotor output line is easy to loosen, and the output end of the conductive slip ring is unstable. Fixing with coil-like items is likely to cause the rotor output line to be entangled, which is difficult to separate it later, and it is not beautiful and inconvenient for users to use during maintenance.

[0044] See also Figure 1-Figure 9 Further on the basis of the first embodiment, the bracket 2 also includes two tooth plates 22, which are respectively installed on the front and rear sides of the bottom of the base plate 20, and a gear 23 adapted to the tooth plate 22 is provided at the bottom of the tooth plate 22.

[0046] The first fixing ring 3 includes a push rod 32 , which is installed at one end of the first fixing ring 3 close to the screw rod 241 . The screw rod 241 is threadedly connected to the inside of the push rod 32 to ensure the normal movement of the first fixing ring 3 .

[0047] The first fixing ring 3 also includes a second fixing ring 30, which is slidably connected to a side surface of the slip ring stator 1 and is arranged at the bottom of the first fixing ring 3. A reset column 31 is sleeved on the bottom of the second fixing ring 30. A spring 310 is fixedly connected inside the reset column 31. The top of the spring 310 is fixedly connected to the bottom of the second fixing ring 30. The length of the spring 310 is greater than the length of the reset column 31, and is used to cooperate with the first fixing ring 3 to fix the rotating shaft.

[0048] Working principle: manually place the rotating shaft into the slip ring rotor 10, at which time the rotating shaft is supported by the second fixing ring 30 and the slip ring rotor 10. In the initial state, in the cross-sectional circle of the slip ring rotor 10, the distance between the second fixing ring 30 and the circle point is less than the distance between the first fixing ring 3 and the center of the circle. The second fixing ring 30 moves downward under the pressure of the rotating shaft, and the spring 310 is elastically deformed under the thrust, and the elastic force generated acts in the opposite direction to the second fixing ring 30 until the second fixing ring 30 stops moving downward. Then the user can manually push the bottom plate 20 in the bracket 2 until the bottom plate 2 0 moves to a position close to the rotor outlet 12, the movement of the bottom plate 20 drives the tooth plate 22 to move, the movement of the tooth plate 22 drives the gear 23 and the meshing rod 24 to rotate, the rotation of the meshing rod 24 drives the bevel gear 240 and the screw 241 to rotate, the rotation of the screw 241 drives the push rod 32 and the first fixed ring 3 to move downward, the first fixed ring 3 moves downward and cooperates with the second fixed ring 30 to fix and clamp the rotating shaft and then continues to move downward until the distance from the second fixed ring 30 to the center of the cross section of the slip ring rotor 10 is equal to the current distance from the first fixed ring 3 to the center of the cross section of the slip ring rotor 10. At this time, the horizontal position of the rotating shaft maintains a straight line, that is, the rotating shaft keeps the center fixed inside the slip ring rotor 10, so that the device can quickly fix the rotating shaft and position it to the center, which is convenient for users to install and use;

[0049] After moving the bottom plate 20 to the rotor outlet line 12, the user can manually place several rotor outlet lines 12 on the bottom of the first wire wheel 250 of the first rotating rod 25, and each first wire wheel 250 corresponds to a rotor outlet line 12. Then the rotor outlet line 12 bypasses the first wire wheel 250 and then goes to the second wire wheel 260, and then goes to the top of the third wire wheel 270 and sticks out a part. In the initial state, the third movable disk 290 at the rear end is clamped at the top plate 28 on the rear side. Then the user can manually push the movable rod 29, and the third movable disk 290 at the rear end is no longer clamped to the top plate 28 on the rear side, and the third movable disk 290 at the front end is clamped to the top plate 28 on the front side. At this time, the clamping plate 291 moves so that each The distance between the clamping plate 291 corresponding to the first wire wheel 250 and the fixed plate 281 is reduced, so as to fix the protruding part of each rotor wire 12. Then the user can manually pull the movable plate 261 through the sliding rod 262 and the sliding groove 21 to pull out all the rotor wires 12 and keep them vertical, thereby completing the fixing and sorting of the wires of the conductive slip ring rotor 10 to avoid their entanglement. The user only needs to reset the movable rod 29 and move the movable plate 261 to adjust the connection distance between the power supply and the conductive slip ring, which is convenient for the user to use. Then, the rotating cover 280 is closed to turn the conductive slip ring over so that the conductive slip ring is supported by the contact plane of the rotating cover 280. The size of the rotating cover 280 can be determined according to the actual situation.

[0050] When the movable plate 261 cannot be used, the user can wind the rotor wire 12 around the first wire wheel 250 or the third wire wheel 270 and push the push block 253 to clamp the clamping column 254 in the clamping slot, thereby completing the fixing and storage of the rotor wire 12. This solution can be used as a replacement solution.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
