Description

Technical Field

[0001] The utility model relates to the technical field of transposed conductor limiting, in particular to a transposed conductor supporting and limiting device. Background Art

[0002] The transposed conductor is a special conductor structure, mainly composed of multiple enameled flat copper wires arranged in a double-helix winding transposition method. These conductors are arranged in two rows with their wide sides touching each other, and are transposed in the same direction along the narrow side above and below the two rows of enameled wires as required. The transposed conductor is also continuously wrapped with electrical insulating paper, rope or tape to improve its insulation performance. The transposed conductor support and limit device is a device used to support and limit the transposed conductor. Its main function is to ensure that the conductor can stably remain in the predetermined position during the storage or processing of the transposed conductor to prevent it from moving or dislocating.

[0003] The existing Chinese patent with announcement number CN114068099B discloses a transposed conductor support and limit device, including an incoming line bottom support and limit device and a lateral jumper limit device; the fixed bracket of the incoming line bottom support and limit device is connected to the guide rail fixed bracket of the lateral anti-jumper limit device; the guide rail fixed bracket is fixedly connected to the external wrapping cage door; the lateral anti-jumper limit device includes a guide rail fixed bracket, a guide rail, a slider, a clamping roller, a clamping rod, a fixed block and an incoming line stop roller; the guide rail is installed on the guide rail fixed bracket, a slider is embedded on the guide rail, and the left and right fixed seats are respectively installed on the slider.

[0004] Although the above scheme utilizes the wire feed stop roller and the limit support roller to timely adjust the center position of the wire after transposition, the stability of the adjustment slider of the device after sliding is insufficient, and it is easy to slide again, affecting the clamping and limiting effect, and will require re-sliding adjustment. At the same time, the two adjustment sliders cannot slide synchronously when the adjustment slider slides, which is easy to produce errors. The position of the wire is offset after clamping and limiting, affecting processing. Therefore, it does not meet existing needs. In this regard, we propose a transposition wire support and limiting device. Utility Model Content

When it is necessary to limit the transposed conductor by the clamp rod, the knob can be turned, and the knob can cause the threaded rod to rotate, thereby driving the two limit blocks to move synchronously in opposite or opposite directions.

The friction generated by the fit between the semicircular block and the rotating shaft can limit the rotating shaft, thereby avoiding the random rotation of the rotating shaft, and further ensuring the stability of the transposed wire after the limit fixation, avoiding affecting the limit of the transposed wire.

[0027] It also includes a fixed box 10, which is welded to one side of the front end of the support platform 1. A moving block 13 is provided inside the fixed box 10, and the moving block 13 is slidably matched with the fixed box 10. A pull rod 11 is welded inside the moving block 13, and both ends of the pull rod 11 pass through and extend to the outside of the fixed box 10, and the pull rod 11 is slidably matched with the fixed box 10.

[0028] When in use, grasp the knob 8 to make the rotating shaft 7 drive the threaded rod 4 to rotate synchronously, and the threaded rod 4 will drive the two limit blocks 6 to rotate synchronously. Under the guidance of the guide rod 5, the rotation of the two limit blocks 6 can be converted into opposite or opposite horizontal linear movement, and the limit block 6 will drive the clamping rod 9 to move synchronously, so that the transposed conductor can be clamped and limited. Since the limit block 6 and the threaded rod 4 are threadedly connected, the stability after movement is guaranteed.

[0029] See also Figure 3 A guide rod 5 is welded on the lower side of the transmission cavity 3. The guide rods 5 all penetrate the limit blocks 6, and the guide rods 5 all slide with the limit blocks 6. The setting of the guide rods 5 can guide the two limit blocks 6, play an axial limit role on the limit blocks 6, and convert the two limit blocks 6 into opposite or opposite horizontal linear movements;

[0030] See also Figure 1 , Figure 2 and Figure 3 A rotating shaft 7 is provided at the front end of the threaded rod 4, one end of the rotating shaft 7 penetrates and extends to the outside of the transmission chamber 3, and the rotating shaft 7 rotates with the transmission chamber 3. A knob 8 is installed at one end of the rotating shaft 7 located outside the transmission chamber 3. The cooperation between the knob 8 and the rotating shaft 7 facilitates the user to rotate the threaded rod 4;

[0031] See also Figure 4 The pull rod 11 is located at one end of the fixed box 10 and is sleeved with a return spring 14. One end of the return spring 14 is connected to the moving block 13, and the other end of the return spring 14 is connected to the fixed box 10.

The setting of the pull block 15 makes it easy for the user to pull the pull rod 11;

[0034] See also Figure 3 The movable seats 16 are connected by a connecting rod 17 , and the setting of the connecting rod 17 increases the connection firmness between the two movable seats 16 .

[0035] Working principle: when in use, the support platform 1 can be moved to the wire-changing machine through the universal wheel 19 with lock, and the electric telescopic rod 18 is started, and the electric telescopic rod 18 will drive the support platform 1 to rise and fall in height. The user can make appropriate adjustments according to needs to meet the needs of different wire-changing machines, which is practical. When limiting the transposed wire, the user can pull the pull block 15, and the pull block 15 will drive the pull rod 11 to move, and the pull rod 11 will drive the moving block 13 to move synchronously. The movement of the moving block 13 will compress the reset spring 14, and the semicircular block 12 will move away from the rotating shaft 7. The user can grab the knob 8 to rotate the rotating shaft 7, and the rotating shaft 7 will drive the threaded rod 4 to rotate synchronously, and the threaded rod 4 will drive the two limit blocks 6 to rotate synchronously. It slides with the guide rod 5, so the rotation of the limit block 6 will be converted into opposite or opposite horizontal linear movement, and the limit block 6 will drive the clamping rod 9 to move synchronously, so that the transposed wire can be clamped and limited. Since the limit block 6 and the threaded rod 4 are threadedly connected, the stability after movement is guaranteed. At the same time, the user can loosen the pull block 15, and the elastic recovery action of the reset spring 14 can make the moving block 13 drive the pull rod 11 to restore its position, so that the pull rod 11 can drive the semicircular resistance block 12 to move, so that the semicircular resistance block 12 fits the outer wall of the rotating shaft 7. The friction force generated by the fit between the semicircular resistance block 12 and the rotating shaft 7 has a limiting effect on the rotating shaft 7, further ensuring the stability of the transposed wire after the limit is fixed, and avoiding affecting the limit of the transposed wire.
