Description

Technical Field

[0001] This utility model relates to the technical field of tensioning conductors for superconducting DC cables, and in particular to a tensioning device for conductors of superconducting DC cables. Background Technology

[0002] Currently, in the process of high-speed cable production, the tensioning device acts as a buffer between the pay-off frame and the production equipment. If the tension of the pay-off frame is too small when an emergency stop occurs, the inertia will cause the cable to become tangled, which is time-consuming and labor-intensive. If the tension is too large, small-diameter cables will be pulled and thinned, and they are also prone to scratches, which greatly reduces the production capacity.

[0003] In existing tensioning devices for superconducting DC cable conductors, such as the one disclosed in utility model patent application number 202021108027.X, when a counterweight plate needs to be installed, a second slider is inserted into a first groove. The second slider moves to the end of the first groove and enters a second groove. The second slider rotates along the second groove to the end of the second groove to prevent it from coming out of the first groove, thus achieving a locking effect between the counterweight plate and the counterweight shaft. Multiple second grooves are arranged in parallel to achieve the effect of increasing or decreasing the counterweight plate according to the required tension.

[0004] However, during the tensioning process of superconducting DC cable conductors, the counterweights need to be moved and placed at any time, which is inconvenient to operate. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a tensioning device for superconducting DC cable conductors, which reduces the complexity of the device and the complicated operation of carrying counterweights back and forth during the tensioning process by setting an adjustment mechanism and a tensioning mechanism, thereby improving the processing efficiency.

[0006] This utility model discloses a tensioning device for a superconducting DC cable conductor, including a guiding mechanism; it also includes an adjusting mechanism, a tensioning mechanism, two sets of moving mechanisms, and four sets of limiting mechanisms. The adjusting mechanism is installed on the guiding mechanism, the tensioning mechanism is installed on the guiding mechanism, the two sets of moving mechanisms are installed on the guiding mechanism, and the four sets of limiting mechanisms are installed on the two sets of moving mechanisms.

[0007] The guiding mechanism provides guidance, the adjusting mechanism adjusts the tension, the tensioning mechanism guides the tension, the moving mechanism moves the cable, and the limiting mechanism limits the cable. The moving mechanism guides the cable during connection, the limiting mechanism limits the cable, the guiding mechanism guides the cable, the tensioning mechanism tensions the cable, and the adjusting mechanism adjusts the tension. This reduces the complexity of the equipment and the cumbersome operation of repeatedly moving counterweights during the tensioning process of the superconducting DC cable conductor, thereby improving processing efficiency.

[0008] Preferably, the guiding mechanism includes a frame and guide wheels, with the guide wheels rotatably mounted on the front end of the frame; the guide wheels guide the cable.

[0009] Preferably, the adjusting mechanism includes a threaded block and a screw. The threaded block is slidably installed in the frame, and the screw is rotatably installed on the frame, with the screw engaging with the threaded block. By rotating the screw and engaging with the threaded block, the threaded block is moved to adjust the tightness of the device.

[0010] Preferably, the tensioning mechanism includes a slider, a spring, and a tensioning wheel. The slider is slidably mounted inside the frame and is connected to the threaded block via the spring. The tensioning wheel is rotatably mounted at the front end of the slider. The slider and the spring support the tensioning wheel to tension the cable.

[0011] Preferably, the moving mechanism includes a second threaded block, a second screw, and a support roller. The second threaded block is slidably mounted on the frame, the second screw is rotatably mounted on the frame, and the second screw and the second threaded block are threadedly engaged. The support roller supports the cable, the second screw and the second threaded block are moved by rotating the screw and the second threaded block, and the second threaded block limits the cable.

[0012] Preferably, the limiting mechanism includes a second slider, a second spring, and a limiting roller. The second slider is slidably mounted on the second threaded block via the second spring, and the limiting roller is rotatably mounted on the lower end of the second slider. The limiting roller is supported by the second slider and the second spring, thereby clamping the cable.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the cable is guided by the moving mechanism, the cable is limited by the limiting mechanism, the cable is guided by the guiding mechanism, the cable is tensioned by the tensioning mechanism, and the tensioning force is adjusted by the adjusting mechanism. Thus, the complexity of the device and the complex operation of moving counterweights back and forth can be reduced during the tensioning process of the superconducting DC cable conductor, thereby improving the processing efficiency.

This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0023] The guiding mechanism 1 includes a frame 11 and a guide wheel 12, with the guide wheel 12 rotatably mounted on the front end of the frame 11;

[0024] The adjusting mechanism 2 includes a threaded block 21 and a screw 22. The threaded block 21 is slidably installed in the frame 11, and the screw 22 is rotatably installed on the frame 11. The screw 22 is threadedly engaged with the threaded block 21.

[0025] The tensioning mechanism 3 includes a slider 31, a spring 32 and a tensioning wheel 33. The slider 31 is slidably installed in the frame 11 and is connected to the threaded block 21 through the spring 32. The tensioning wheel 33 is rotatably installed at the front end of the slider 31.

[0028] The cable is supported by a support roller 43. The screw 42 rotates and engages with the threaded block 41 to move the threaded block 41, which then limits the cable. The slider 51 and spring 52 support the limiting roller 53 to clamp the cable. The guide wheel 12 guides the cable. The slider 31 and spring 32 support the tensioning wheel 33 to tension the cable. The screw 22 rotates and engages with the threaded block 21 to move the threaded block 21 and adjust the tension of the equipment.
