Description

Technical Field

[0001] This utility model relates to the field of superconducting wire laying technology, specifically to a superconducting wire precision laying tension adaptive constant device. Background Technology

[0002] Superconducting wires are wires made of superconducting materials. Superconducting materials are those whose electrical resistance suddenly disappears under certain temperature and magnetic field conditions, exhibiting special physical properties such as perfect diamagnetism. When a material is in a superconducting state, current can be transmitted without loss, without heat loss due to resistance, thus enabling highly efficient power transmission and other special applications.

[0003] In the process of superconducting cable laying, a tension-consistent device is required. Chinese utility model patent CN208071000U discloses a superconducting cable laying tension device, including a fixed frame, a pull-down spring, and an upper pull-up spring. A wire cylinder is located at the right end of the fixed frame, a compression ball is located inside the heating layer, and a contact pad is located at the outer end of the pressure-reducing spring. The pull-down spring is located at the lower end of the fixed frame, and a lower roller shaft is located above it. The upper pull-up spring is located at the upper end of the fixed frame, and a bearing is located at the lower end of the connecting frame. A fixing rod is located on the left side of the upper roller shaft, a connecting shaft is located inside the upper fixing shaft, and a lower fixing shaft is located below the upper fixing shaft. This utility model solves the problem of low utilization rate of superconducting cables due to entanglement during laying in most superconducting cable laying tension devices, and also solves the problem of superconducting cables easily breaking when operating in low-temperature environments.

[0004] However, in use, this device, by simply setting up upper and lower springs, cannot adjust the tension of the superconducting wire. During the wire feeding process, the superconducting wire may bounce up and down, thereby accelerating the wear on its surface and failing to meet production requirements. Therefore, a precision wire feeding tension adaptive constant device for superconducting wire is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a precision tension adaptive constant device for superconducting wire, which has the advantage of facilitating the adjustment of superconducting wire tension. It solves the problem that the existing device, which only uses upper and lower springs, cannot adjust the tension of the superconducting wire. During the wire feeding process, the superconducting wire may bounce up and down, thereby accelerating the wear of its surface and failing to meet production requirements.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precision tension adaptive constant device for superconducting wire, comprising a base and a drive box fixedly connected to the top of the base, wherein the drive box is provided with a tension adjustment mechanism capable of adjusting the tension of the superconducting wire.

[0007] The tension adjustment mechanism includes two tension guide wheels slidably connected to the front of the drive box. A drive motor is fixedly installed on the back of the drive box. A transmission gear extending into the drive box is fixedly connected to the output shaft of the drive motor. Two lifting racks meshing with the transmission gear are slidably connected inside the drive box. A connecting plate is fixedly connected to the side of each of the two lifting racks that are separated from each other. A connecting shaft is rotatably installed between the connecting plate and the tension guide wheels.

[0008] Furthermore, the front of the drive box is provided with a positioning groove that matches the connecting shaft, and the inside of the connecting plate is provided with a through-hole that matches the lifting rack.

[0009] Furthermore, a support frame is fixedly installed on the top of the base, and two movable blocks are slidably connected inside the support frame. A positioning roller is rotatably connected between the two movable blocks, and a threaded rod extending to the top of the support frame is rotatably connected to the top of the movable blocks. A rotating handle is fixedly connected to the top of the threaded rod.

[0010] Furthermore, a positioning guide rod extending to the top of the support frame is fixedly connected to the top of the movable block on the back side, the inner wall of the movable block is in contact with the inner wall of the support frame, and the back side of the movable block is on the same horizontal plane as the inner wall of the support frame.

[0011] Furthermore, a support plate is fixedly connected to both the front and back of the top of the base, and a cable tube is provided between the two support plates. One end of the cable tube is fixedly connected to a positioning plate extending to the front of the support plate.

[0012] Furthermore, an electric push rod is fixedly installed on the top of the base, and a positioning cylinder is fixedly connected to the output end of the electric push rod. A line-setting roller is rotatably installed inside the positioning cylinder.

[0013] Furthermore, four casters are rotatably mounted on the bottom of the base, and the four casters are evenly distributed on the bottom of the base.

[0014] Compared with the prior art, this utility model provides a device for adaptive constant tension of precision wire feeding of superconducting wire, which has the following beneficial effects:

[0015] 1. This superconducting wire precision tension adaptive constant device uses a drive motor to rotate a transmission gear, which in turn drives two lifting racks to move up and down simultaneously. The two lifting racks move in opposite directions, allowing them to simultaneously drive two tensioning guide wheels to move up and down. This facilitates adjustment of the tension during superconducting wire laying and allows for adjustment based on the actual conditions during the laying process, thus improving the device's practicality.

[0016] 2. This precision tension adaptive constant device for superconducting wire, by setting a moving block and a positioning roller, can position the superconducting wire and simultaneously apply a certain pressure to it, preventing the superconducting wire from becoming too loose during the unwinding process. By rotating the rotating handle to drive the threaded rod to rotate, the moving block can be raised and lowered, thereby adjusting the pressure on the superconducting wire. This solves the problem that the current device, which only uses upper and lower pull springs, cannot adjust the tension of the superconducting wire. During the unwinding process, the superconducting wire may bounce up and down, thus accelerating its surface wear and failing to meet production requirements. Attached Figure Description

[0025] Specifically, the front of the drive box 2 is provided with a positioning groove 8 that matches the connecting shaft, and the inside of the connecting plate 7 is provided with a through opening 9 that matches the lifting rack 6.

[0026] It should be noted that a controller is fixedly installed on the front of the top of the base 1, and tension sensors are fixedly installed on both tension guide wheels 3.

[0030] It should be noted that by setting the moving block 11 and the positioning roller 12, the superconducting wire can be positioned, thereby applying a certain pressure to the superconducting wire to prevent it from being too loose during the wire laying process. Furthermore, by rotating the rotating handle 14 to drive the threaded rod 13 to rotate, the moving block 11 can be moved up and down, thereby adjusting the pressure on the superconducting wire.

Next, one end of the superconducting wire is pulled out, passes through the bottom of the positioning roller 12, and rests on the two tensioning guide rollers 3. Then, it passes through the positioning drum 19. At this time, the drive motor 4 is started to move the two tensioning guide rollers 3 to adjust the tension of the superconducting wire. At the same time, the rotating handle 14 is rotated to fine-tune the tension of the superconducting wire. After that, the wire feeding process can be completed.
