Description

A wire stranded tension balance counterweight wheel assembly Technical Field

[0001] This utility model relates to the field of wire stranding technology, and in particular to a wire stranding tension balance counterweight wheel assembly. Background Technology

[0002] With the development of science and technology, superconducting magnet technology has been increasingly applied. The core of a superconducting magnet is a superconducting conductor, which has the characteristics of good self-support, low AC loss, less need for cryogenic cooling medium, safe and reliable operation, and high performance. It is currently recognized internationally as the preferred conductor for large superconducting magnets and other devices in controlled thermonuclear fusion devices. CICC superconducting conductor is a multi-stage tubular cable, which is composed of five strands. The first stage sub-cable is composed of several copper wires and several superconducting wires stranded at a certain stranding pitch. Then, several sub-cable units are stranded at a certain stranding pitch to form the second stage sub-cable. Similarly, the third and fourth stage sub-cables are formed, and finally, the fifth stage cable is formed. CICC superconducting conductor is composed of many extremely fine superconducting wires. The stranded superconducting strands reach 1154, and the diameter of each superconducting strand is only 0.73±0.003mm.

[0003] During the stranding process of CICC superconducting conductors, it is required that the tension during the unwinding beading be appropriate and consistent. Because the superconducting strands are extremely thin, if the tension during stranding is too high, the superconducting strands are very easy to break; if the tension is too low, the stranded cable is easily damaged and not tight. If the tension is inconsistent, the stranded cable will exhibit phenomena such as serpentine shape and bending.

[0004] However, in the existing conductor stranding tension balancing counterweight wheel sets, most of the tension wheel sets only have one tension wheel set that can be adjusted during operation, which makes them less versatile. Moreover, after long-term use, the tension wheel set is prone to wear, which leads to a deterioration in the conductor stranding quality. Furthermore, the tension wheel set is not easy for workers to quickly disassemble and assemble, which affects the working efficiency of the device. Summary of the Invention

[0005] In order to overcome the shortcomings of existing tension balancing weight wheel sets for conductor stranding, which typically only have one adjustable tension wheel set during operation, resulting in limited applicability, and the tendency for the tension wheel to wear out over time, leading to poor conductor stranding quality, and the inconvenience of quickly assembling and disassembling the tension wheel, the working efficiency of the device is affected.

[0006] The technical solution of this utility model is as follows: a wire stranded tension balance counterweight wheel assembly, including a supporting base plate, a displacement seat movably connected to the front end of the supporting base plate, a movable groove provided on the inner side of the rear end of the displacement seat located on the supporting base plate, the rear end of the displacement seat extending to the inner side of the movable groove, a first knob provided at the top end of the supporting base plate, a first lead screw provided at the bottom end of the first knob, the bottom end of the first lead screw extending through the displacement seat to the bottom end of the inner wall of the movable groove, a mounting base provided at the front end of the displacement seat, a mounting block fixedly connected to the inner side of the mounting base, a locking block provided on both sides of the mounting block, a second knob and a tension wheel sequentially provided on the front end face of the mounting block, a second lead screw provided behind the second knob located on the inner side of the mounting block, the two ends of the second lead screw extending through the locking blocks to the inner side of the mounting block.

[0007] Preferably, three sets of tension wheels are provided, and the three sets of tension wheels can be adjusted separately by three first knobs, which makes it convenient for the staff to adjust the tension according to the strength of different wires, thus improving the applicability of the device. By rotating the second knob, the second knob, in conjunction with the transmission rod and bevel gear, drives the second lead screw to rotate, thereby causing the second lead screw to drive the locking block to insert into the inside of the mounting base, which makes it convenient for the staff to disassemble and replace the mounting base and tension wheels.

[0009] Preferably, the first knob and the first lead screw are an integral structure. The bottom end of the first lead screw is provided with a threaded hole on the inner side of the displacement seat. The bottom end of the first lead screw extends through the threaded hole to the bottom end of the inner wall of the movable groove. The first lead screw and the displacement seat mesh with each other.

[0010] Preferably, the inner side of the mounting base is provided with a mounting groove, the shape of which is consistent with the shape of the rear end of the mounting block, and the rear end of the mounting block is inserted into the inner side of the mounting groove.

[0014] Preferably, one end of the card block is provided with a card slot inside the mounting base, and one end of the card block is consistent with the shape of the card slot, and one end of the card block is inserted into the inside of the card slot.

[0015] The beneficial effects of this utility model are:

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to Figures 1-5. This utility model provides a technical solution: a wire stranded tension balancing counterweight wheel assembly, including a support base plate 1, a displacement seat 2 movably connected to the front end of the support base plate 1, a movable groove 4 provided on the inner side of the rear end of the displacement seat 2 located on the support base plate 1, the rear end of the displacement seat 2 extending into the inner side of the movable groove 4, a first knob 3 provided at the top end of the support base plate 1, a first lead screw 5 provided at the bottom end of the first knob 3, the bottom end of the first lead screw 5 penetrating the displacement seat 2 and extending to the bottom end of the inner wall of the movable groove 4, the front end of the displacement seat 2... A mounting base 6 is provided, and a mounting block 7 is fixedly connected to the inner side of the mounting base 6. Both sides of the mounting block 7 are provided with locking blocks 11. The front end face of the mounting block 7 is provided with a second knob 8 and a tension wheel 9 in sequence. Behind the second knob 8, a second lead screw 13 is provided on the inner side of the mounting block 7. The two ends of the second lead screw 13 pass through the locking blocks 11 and extend to the inner side of the mounting block 7. By rotating the first knob 3, the position of the tension wheel 9 can be adjusted through the first lead screw 5, which makes it convenient for the staff to adjust the tension according to the strength of different wires.

[0025] Please refer to Figures 2-3. In this embodiment, positioning pins 14 are provided at all four ends of the support base plate 1. One end of the positioning pin 14 is located inside the support base plate 1 and is provided with a positioning hole. The other end of the positioning pin 14 extends to the inside of the positioning hole. The first knob 3 and the first lead screw 5 are integral structures. The bottom end of the first lead screw 5 is located inside the displacement seat 2 and is provided with a threaded hole. The bottom end of the first lead screw 5 extends through the threaded hole to the bottom end of the inner wall of the movable groove 4. The first lead screw 5 and the displacement seat 2 mesh with each other, thereby facilitating the connection of the support base plate 1 with other equipment through the positioning pins 14.

[0026] Please refer to Figures 4 and 5. The inner side of the mounting base 6 is provided with a mounting groove 15, the shape of which is consistent with the shape of the rear end of the mounting block 7. The rear end of the mounting block 7 is inserted into the inner side of the mounting groove 15. The rear end of the second knob 8 is provided with a transmission rod 12, one end of which extends to the center of the second lead screw 13. A bevel gear 10 is provided at the intersection of the transmission rod 12 and the second lead screw 13. The transmission rod 12 and the second lead screw 13 are connected by the bevel gear 10. The lead screw 13 is a double-threaded lead screw. The threads at both ends of the second lead screw 13 are symmetrical about the second lead screw 13. The second lead screw 13 meshes with two locking blocks 11. One end of the locking block 11 is located inside the mounting base 6 and has a locking groove. One end of the locking block 11 is consistent with the shape of the locking groove. One end of the locking block 11 is inserted into the inside of the locking groove. Then, by rotating the second knob 8, the second knob 8, together with the transmission rod 12 and the bevel gear 10, drives the second lead screw 13 to rotate. The second lead screw 13 meshes with the two locking blocks 11, so that the second lead screw 13 drives the locking blocks 11 to insert into the inside of the mounting base 6, which makes it convenient for the staff to disassemble and assemble the mounting base 6 and the tension wheel 9.

[0027] When working, place the device in a suitable position and connect the support base plate 1 to the wall or other equipment through the positioning pin 14. Then, pass the wire through the three tension wheels 9 in sequence and connect it to other stranding equipment. There are three sets of tension wheels 9, and the three sets of tension wheels 9 can be adjusted separately through the three first knobs 3. This allows the operator to adjust the tension according to the strength of different wires, improving the applicability of the device. When the tension wheels 9 wear out after long-term use, the second knob 8 is rotated. The second knob 8, in conjunction with the transmission rod 12 and the bevel gear 10, drives the second lead screw 13 to rotate. The second lead screw 13 meshes with the two locking blocks 11, so that the second lead screw 13 drives the locking blocks 11 to insert into the inside of the mounting base 6, which facilitates the operator to disassemble and replace the mounting base 6 and the tension wheels 9.

[0028] Through the above steps, three sets of tension wheels 9 are provided, and the three sets of tension wheels 9 can be adjusted separately by three first knobs 3. This allows the staff to adjust the tension according to the strength of different wires, improving the applicability of the device. By rotating the second knob 8, the second knob 8, in conjunction with the transmission rod 12 and the bevel gear 10, drives the second lead screw 13 to rotate, thereby causing the second lead screw 13 to drive the locking block 11 to insert into the inside of the mounting base 6. This facilitates the disassembly, assembly, and replacement of the mounting base 6 and tension wheels 9 by the staff. This solves the problem that in the existing wire stranding tension balancing counterweight wheel group, most of the tension wheel groups only have one tension wheel group that can be adjusted during operation, resulting in weak applicability. Moreover, after long-term use, the tension wheels are prone to wear, leading to a deterioration in the wire stranding quality. Furthermore, the tension wheels are not easy for the staff to quickly disassemble and assemble, affecting the working efficiency of the device.
