Description

Technical Field

[0001] The invention relates to the technical field of cable testing equipment, in particular to a cable low-temperature winding testing device. Background Art

[0002] As a key test method for evaluating the cold resistance of wires and cables in extreme cold environments, the low-temperature winding test is designed to accurately verify the operational reliability and stability of wire and cable products in extremely cold regions or under low-temperature working conditions. The test requires completing a predetermined cooling process in a low-temperature chamber and ensuring that the ambient temperature strictly meets the conditions set by the test specifications before the test process can be officially started.

[0003] In the specific test operation, the winding device and the wires and cables to be tested need to be placed in a low-temperature box as a whole to simulate the actual low-temperature application scenario. The existing winding device is usually composed of core components such as a bracket, a winding rod, a guide tube and a pressure roller. During the test, the cable is precisely guided and wound onto the winding rod through the guide tube. At the same time, the tightness and uniformity of the cable winding are ensured with the help of the pressing effect of the pressure roller. However, since the diameter of the existing winding rod is designed to be a fixed value, when the test requirements involve testing the performance of the same cable at different bending angles, the staff have to frequently disassemble and replace winding rods of different diameters to the bracket. This process is not only cumbersome, time-consuming and labor-intensive, but also significantly reduces the overall efficiency of the test. For this reason, we propose a cable low-temperature winding test device. Summary of the Invention

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figures 1-10 The present invention provides a technical solution: a low-temperature cable winding test device, comprising a bracket 1 and a guide tube 11 arranged on the bracket 1, and further comprising:

[0034] The winding rod 2 is rotatably mounted on the bracket 1 and has a mounting hole for fixing the cable end.

[0035] The drive assembly 3 is provided on the bracket 1 and connected to the winding rod 2. The drive assembly 3 includes a third shaft 76 fixedly connected to the winding rod 2. The third shaft 76 is rotatably connected to the bracket 1. The bracket 1 is fixedly connected to a drive shaft and a second drive motor 77 fixed to the third shaft 76. The drive assembly 3 is used to drive the winding rod 2 to rotate to achieve cable winding. The winding rod 2 has a conical structure. During the cable winding test, the bending angle of the cable is gradually increased, thereby continuously completing tests of different bending angles of the same cable.

[0036] The pressing roller 4 is tilted and arranged on the bracket 1, and is used to cooperate with the winding rod 2 to squeeze the cable so that the cable can be wound more tightly and regularly;

[0037] The C-shaped plate 5 is slidably arranged on the bracket 1 and connected to the guide tube 11, and a plurality of fan-shaped plates 6 are equidistantly and evenly slidably connected to one side of the C-shaped plate 5, which are used to limit the cable wound on the winding rod 2. Specifically, when the device is in use, the cable starts from the end with a larger diameter of the winding rod 2 and gradually winds it to the end with a smaller diameter, so as to achieve a smooth transition from a small to a large bending angle of the cable. However, during the winding process, there is a risk that the wound cable will slide along the winding rod 2 and become loose. For this reason, the device is provided with a plurality of fan-shaped plates 6 on the C-shaped plate 5. These fan-shaped plates 6 can effectively support the wound cable and prevent it from becoming loose.

[0038] The translation assembly 7 is provided on the bracket 1 and is connected to the C-shaped plate 5 and the guide tube 11, and is used to drive the C-shaped plate 5 and the guide tube 11 to move while the winding rod 2 is winding the cable;

[0039] Specifically, the device adopts a conical winding rod 2. During the cable winding process, the bending angle of the cable will gradually increase with the change of the winding position. Based on this feature, the same winding rod 2 can be used to continuously carry out cable tests at different bending angles. There is no need to frequently replace winding rods 2 with different diameters, which significantly improves the test efficiency. When the winding rod 2 is performing the cable winding operation, the cable will exert an extrusion effect on the L-shaped slide 52. This extrusion action will trigger the drive motor 51 to work. After the drive motor 51 is running, it will synchronously drive the fan plate 6 and the guide tube 11 to move along the winding direction. Through this coordinated movement mechanism, the loosening of the cable during the winding process is effectively avoided, ensuring that the cable can be tightly and regularly wound on the winding rod 2.

[0040] A round rod 41 is fixedly connected to one side of the fan-shaped plate 6. Specifically, a rectangular plate 86 is fixedly connected between the fan-shaped plate 6 and the round rod 41. A sliding groove 87 is provided on the C-shaped plate 5, which is connected to the sliding groove 42. The rectangular plate 86 is located in the sliding groove 87 and is slidably connected to its inner wall. A sliding groove 42 is provided on the C-shaped plate 5, and the round rod 41 is located in the sliding groove 42 and is slidably connected to its inner wall. A tension spring 43 is provided on the round rod 41, whose two ends are respectively fixed to the round rod 41 and the C-shaped plate 5, so that one end of the round rod 41 is always in contact with the winding rod 2. Specifically, when the C-shaped plate 5 moves along the conical winding rod 2, under the continuous action of the elastic force of the tension spring 43, the end of the round rod 41 can always fit closely to the surface of the winding rod 2. In this way, the fan-shaped plate 6 can also always fit in with the surface of the winding rod 2, thereby providing stable and good support for the cable wound on the winding rod 2.

[0041] The translation assembly 7 includes a sliding block 44 slidably disposed in the bracket 1, the guide tube 11 is connected to the sliding block 44, and a C-shaped slide 45 is provided on one side of the C-shaped plate 5, and a connecting rod 46 is fixedly connected between the C-shaped slide 45 and the sliding block 44;

[0042] A guide rod 47 is fixedly connected to the bracket 1 and slides through the sliding block 44. A shaft 48 is rotatably connected to the bracket 1. A screw 49 is fixedly connected to the shaft 48 and threadedly penetrates the sliding block 44. A drive motor 51 is fixedly connected to the bracket 1 and is fixedly connected to the shaft 48. When the drive motor 51 is started, the shaft 48 is rotated to rotate the screw 49, thereby driving the sliding block 44 to move, and further driving the C-shaped slide 45, the C-shaped plate 5, and the guide tube 11 to move.

[0043] An L-shaped slide 52 is provided between the winding rod 2 and the nip roller 4. The L-shaped slide 52 is connected to the C-shaped slide 45. A control assembly 53 connected to the L-shaped slide 52 and the drive motor 1 51 is provided on the bracket 1. The control assembly 53 is used to control the drive motor to operate when the cable wound onto the winding rod 2 is squeezed against the L-shaped slide 52, thereby driving the sliding block 44 to move.

[0044] Specifically, by precisely adjusting the gap width between the pressing roller 4 and the winding rod 2, the gap is made to allow only a single cable to pass through. When the winding rod 2 starts the cable winding operation, as the cable is continuously wound around the winding rod 2, the cable will exert an extrusion effect on the L-shaped slide 52, and then transmit the pressure to the pressure sensor 73 provided on the L-shaped slide 52. After the pressure sensor 73 senses the pressure change, it will send a control signal to start the drive motor 51. After the drive motor 51 is running, it will drive the L-shaped slide 52, the guide tube 11, the C-shaped slide 45, the C-shaped plate 5 and the fan plate 6 to move synchronously, so that these components can closely follow the cable winding process.

[0045] A U-shaped frame 54 is provided in the bracket 1, and the pressing roller 4 is rotatably connected to the U-shaped frame 54 through a rotating shaft, and a sliding rod 55 with one end sliding through the bracket 1 is fixedly connected to the U-shaped frame 54, and a screw 2 56 is rotatably connected to the U-shaped frame 54. One end of the screw 2 56 is threaded through the bracket 1 and is fixedly connected to a handwheel 57. By rotating the handwheel 57, the screw 2 56 is driven to rotate, and then the U-shaped frame 54 and the pressing roller 4 are driven to move, so as to adjust the gap between the pressing roller 4 and the winding rod 2 to adapt to cables of different diameters and improve the applicability of the device.

[0046] A U-shaped frame 2 58 is slidingly provided on one side of the U-shaped frame 1 54, and a guide rod 59 parallel to the pressing roller 4 is fixedly connected to the U-shaped frame 2 58, and the L-shaped slide 52 is slidingly connected to the guide rod 59. A push plate 61 is provided on one side of the L-shaped slide 52 and is slidingly connected to the guide rod 59. The push plate 61 is rotatably connected to the connecting rod 1 62 through a rotating shaft, and a connecting rod 2 63 is rotatably connected between the C-shaped slide 45 and the connecting rod 1 62 through a rotating shaft. This design can synchronously drive the L-shaped plate to move when the C-shaped slide 45 moves, and at the same time allow the L-shaped slide 52 to slide along the guide rod 59 without interfering with the movement of the L-shaped slide 52.

[0047] The U-shaped frame 58 is fixedly connected to the second slide rod 64 that is slidably connected to the first U-shaped frame 54. The U-shaped frame 58 is rotatably connected to the third screw 65. The U-shaped frame 54 is fixedly connected to the first hollow cylinder 66. One end of the third screw 65 passes through the hollow cylinder 66 and is connected to the hollow cylinder 66 by a thread.

[0048] One end of the screw rod 3 65 is fixedly connected to the shaft 2 67, and the U-shaped frame 1 54 is rotatably connected to the gear plate 1 68. One end of the shaft 2 67 slides through the gear plate 1 68. A guide groove 69 is provided on the shaft 2 67. A guide protrusion 71 is fixedly connected to the inner wall of the gear plate 1 68, and the guide protrusion 71 is slidably connected to the guide groove 69. One end of the screw rod 2 56 is fixedly connected to the gear plate 2 72 meshing with the gear plate 1 68, which is used to rotate the screw rod 2 56 to drive the gear plate 1 When the pressing roller 4 moves and the distance between the pressing roller 4 and the winding rod 2 is adjusted, the transmission action of the toothed disc 2 72 drives the toothed disc 1 68 to rotate, and the rotation of the toothed disc 1 68 will further drive the shaft 2 67 and the screw 3 65 to rotate synchronously. The rotation of the screw 3 65 drives the U-shaped frame 2 58 and the L-shaped slide 52 to move relative to the pressing roller 4. In this way, the L-shaped slide 52 can always be accurately in the middle position of the gap between the pressing roller 4 and the winding rod 2.

[0049] The control assembly 53 includes a pressure sensor 73 mounted on one side of the push plate 61. The pressure sensor 73 is electrically connected to the controller of the drive motor 51. A spring 74 mounted on the guide rod 59 is fixedly connected to one side of the L-shaped slide 52. One end of the spring 74 is fixedly connected to an extrusion plate 75. The guide rod 59 slides through the extrusion plate 75, and the pressure sensor 73 is connected to the extrusion plate 75.

[0050] During specific use, the cable is passed through the guide tube 11, and then the cable end is clamped in the mounting hole of the winding rod 2. Then the drive motor 51 is started to rotate, driving the L-shaped slide 52 to press against one side of the cable and compress the spring 1 74, so that the pressure sensor 73 has a certain pressure value. Then the drive motor 2 77 is started to drive the winding rod 2 to wind the cable. During the cable winding operation, as the cable is continuously wound, the L-shaped slide 52 will gradually be squeezed. This squeezing action will further compress the spring 1 74, thereby causing the pressure value detected by the pressure sensor 73 to increase. After the pressure sensor 73 senses the pressure change, it will send a control signal, and the drive motor 51 will start and rotate accordingly. The power generated by the motor rotation will drive multiple related components to move in coordination, so that these components can fit closely with the cable winding process and achieve synchronous movement.

[0051] One side of the C-shaped plate 5 is fixedly connected to a plurality of sliding rods 3 78, each of which slides through the C-shaped slide plate 45 at one end, and a spring 2 79 is sleeved on the sliding rod 3 78, with its two ends respectively fixed to the C-shaped plate 5 and the C-shaped slide plate 45. With this design, when the fan-shaped plate 6 plays the role of blocking the loose cables, the spring 2 79 can better fit the cables under the elastic force of the spring 2, thereby improving the blocking effect and stability of the cables.

[0052] At the same time, the contact surface between the fan-shaped plate 6 and the cable is designed with elastic material to better fit the cable.

[0053] Example 2: Please refer to Figures 1-11 , the present invention provides a technical solution: Example 2 is optimized based on Example 1;

[0054] The guide tube 11 is fixedly connected to a slide rod 481 with one end sliding through the sliding block 44, and the guide tube 11 is fixedly connected to a screw rod 482. The sliding block 44 is rotatably connected to a threaded sleeve 83 threadedly penetrated by the screw rod 482. One end of the threaded sleeve 83 is fixedly connected to an outer gear ring 84, and the bracket 1 is fixedly connected to a rack 85 meshing with the outer gear ring 84. With this design, when the sliding block 44 drives the guide tube 11 to move along the winding rod 2, the diameter of the winding rod 2 tends to gradually decrease. The winding position of the cable will continue to decrease accordingly. To adapt to this change, the outer gear ring 84 will move along the rack 85, thereby driving the threaded sleeve 83 to rotate. The rotation of the threaded sleeve 83 will drive the screw rod 82 and the guide tube 11 connected thereto to move downward together, thereby realizing dynamic adjustment of the height of the guide tube 11 so that it always matches the winding position. In this way, excessive friction between the cable and the guide tube 11 due to position mismatch can be effectively avoided, and the guiding process can be smoother.
