Description

Technical Field

[0001] This invention relates to the field of cable testing equipment technology, and more specifically, to a cable torsion testing device. Background Technology

[0002] Composite optical fiber grounding wire, also known as fiber optic composite overhead grounding wire, is a communication cable that uses one or more optical fibers encased in a protective sheath as the transmission medium and can be used individually or in groups. With increasing market demand, the requirements for the structural strength and performance of cables are becoming more stringent. To ensure that the cable's performance remains unchanged under complex environments, it is necessary to conduct torsional resistance tests on the cable to meet usage requirements.

[0003] In related technologies, the torsional resistance of a cable is tested by fixing one end of the cable to a clamp and driving the other end of the cable with a motor to perform a torsion test.

[0004] However, the inability to adjust the degree of cable twist in the relevant technology makes it impossible to test different degrees of cable twist. Summary of the Invention

[0012] Furthermore, the first rotating component includes a rotating disk having a communicating cavity, one end of an adjusting block being movably inserted into the communicating cavity, the top wall of the rotating disk having a through-hole clearance hole, and a locking assembly passing through the clearance hole and being disposed in one of the mounting holes.

[0013] Furthermore, the second rotating component includes a cable bundle and a rotating rod. The cable bundle is mounted on the rotating rod, and the rotating rod is rotatably mounted on the mounting platform with the center of the cable bundle as its rotation center. The second cable fixing part is mounted on the cable bundle, and the adjusting block of the first rotating component is slidably connected to the rotating rod.

[0014] Furthermore, the second cable fixing part includes: a threaded sleeve, the outer wall of the cable bundle tube is provided with an external thread, the internal thread of the threaded sleeve is threadedly connected to the external thread of the cable bundle tube, the upper end of the threaded sleeve is provided with a pressing slope, the cross-sectional size of the pressing slope gradually decreases from top to bottom; at least two cable fixing blocks are disposed inside the cable bundle tube, the first end of the cable fixing block extends toward the center of the cable bundle tube, the second end of the cable fixing block extends toward the direction away from the center of the cable bundle tube, and the pressing slope abuts against the second end of the cable fixing block; a third elastic member is disposed inside the cable bundle tube, the first end of the third elastic member is connected to the inner wall of the cable bundle tube, and the second end of the third elastic member is connected to the cable fixing block.

[0015] Furthermore, an arc-shaped plate is provided on the rotating rod, and an arc-shaped groove is provided on the mounting platform. The center of the arc-shaped plate and the arc-shaped groove coincides with the rotation center of the wire bundle.

A first cable fixing part is provided on the mounting platform, and a second cable fixing part is provided below the first cable fixing part on the second rotating component, thereby fixing the cable. The first and second rotating components are slidably connected, so that when the first rotating component is driven to rotate, the second rotating component rotates relative to the mounting platform around the second cable fixing part as its rotation center.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1 to 8As shown, this embodiment of the invention provides a cable torsion testing device, which includes a mounting platform 10 and a testing component 20. The mounting platform 10 is provided with a first cable fixing part 11. The testing component 20 includes a first rotating member 21 and a second rotating member 22. Both the first rotating member 21 and the second rotating member 22 are rotatably mounted on the mounting platform 10. The second rotating member 22 is provided with a second cable fixing part 221 located below the first cable fixing part 11. The first rotating member 21 and the second rotating member 22 are slidably connected to drive the second rotating member 22 to rotate relative to the mounting platform 10 with the second cable fixing part 221 as the rotation center. The first rotating member 21 is provided with an adjusting block 211. The first rotating member 21 is slidably connected to the second rotating member 22 through the adjusting block 211. The adjusting block 211 is adjustablely positioned on the first rotating member 21 to adjust the maximum rotation angle of the second rotating member 22.

[0036] The cable torsion testing device provided in this embodiment includes a mounting platform 10 and a testing component 20. The testing component 20 includes a first rotating member 21 and a second rotating member 22. Both the first rotating member 21 and the second rotating member 22 are rotatably mounted on the mounting platform 10. A first cable fixing part 11 is provided on the mounting platform 10. A second cable fixing part 221 is provided below the first cable fixing part 11 on the second rotating member 22, thereby fixing the cable. The first rotating member 21 and the second rotating member 22 are slidably connected. Thus, when the first rotating member 21 is driven to rotate, the second rotating member 22 can be driven to rotate relative to the mounting platform 10 with the second cable fixing part 221 as the rotation center. Since the first cable fixing part 11 on the mounting platform 10 fixes the cable and does not rotate, the torsion resistance of the cable can be tested when the second cable fixing part 221 rotates. An adjusting block 211 is provided on the first rotating member 21. The adjusting block 211 is positionally adjustable on the first rotating member 21, thereby allowing the length of the adjusting block 211 to be adjusted. Since the adjusting block 211 can be slidably connected to the second rotating member 22, when the length of the adjusting block 211 is adjusted, the maximum rotation angle of the second rotating member 22 can be adjusted, thereby enabling the testing of the anti-torsion performance of the cable at different degrees of torsion and improving the accuracy of the cable anti-torsion performance test.

[0037] It should be noted that when the angle between the adjusting block 211 of the first rotating member 21 and the second rotating member 22 reaches 90° during rotation, the cable experiences the maximum degree of torsion. When adjusting the position of the adjusting block 211, the position where the adjusting block 211 and the second rotating member 22 form a 90° angle can be adjusted. For example, when the adjusting block 211 moves inward into the first rotating member 21, the first rotating member 21 only needs to swing the second rotating member 22 by a small angle to make the angle between the adjusting block 211 and the second rotating member 22 90°, at which point the cable has a lower degree of torsion. When the adjusting block 211 moves outward from the first rotating member 21, the first rotating member 21 needs to swing the second rotating member 22 by a larger angle to make the angle between the adjusting block 211 and the second rotating member 22 90°, at which point the cable has a higher degree of torsion.

[0038] like Figures 1 to 3 As shown, the cable torsion test device also includes a locking assembly 30. The adjusting block 211 is provided with a plurality of mounting holes 2111 arranged along the moving path of the adjusting block 211. The locking assembly 30 has a locking position and a clearance position. When the locking assembly 30 is in the locking position, the locking assembly 30 passes through one of the mounting holes 2111 to fix the adjusting block 211. When the locking assembly 30 is in the clearance position, the locking assembly 30 is disengaged from the mounting hole 2111. With the above structure, by setting the locking component 30, multiple mounting holes 2111 are provided on the adjusting block 211. When the position of the adjusting block 211 is adjusted, the locking component 30 is used for locking and clearance. Therefore, when the adjusting block 211 needs to be locked, the locking component 30 is inserted through one of the mounting holes 2111 of the adjusting block 211. In this way, when the locking component 30 is in the locked position, the adjusting block 211 can be locked and fixed. When the position of the adjusting block 211 needs to be adjusted, the locking component 30 is disengaged from the mounting hole 2111. In this way, when the locking component 30 is in the clearance position, the adjusting block 211 can be moved easily, ensuring that the anti-torsion performance of the cable with different degrees of torsion can be tested.

[0039] like Figures 1 to 3As shown, the locking assembly 30 includes a mounting bracket 31, a fixing rod 32, and a first elastic member 33. The mounting bracket 31 is disposed on the first rotating member 21. The fixing rod 32 is movably disposed on the first rotating member 21 in a vertical direction. The upper end of the fixing rod 32 is movably inserted through the mounting bracket 31, and the lower end of the fixing rod 32 can extend into one of the mounting holes 2111. The first elastic member 33 is sleeved on the fixing rod 32. The upper end of the first elastic member 33 is connected to the mounting bracket 31, and the lower end of the first elastic member 33 is connected to the fixing rod 32. With the above structure, by setting up a mounting bracket 31, a fixing rod 32, and a first elastic element 33, the mounting bracket 31 is set on the first rotating member 21, the upper end of the fixing rod 32 is movably set on the mounting bracket 31, and the lower end of the fixing rod 32 can extend into one of the mounting holes 2111. The first elastic element 33 is sleeved on the fixing rod 32. When it is necessary to adjust the position of the adjusting block 211, the fixing rod 32 needs to be pulled upward, the first elastic element 33 is compressed, so that the fixing rod 32 moves upward relative to the mounting bracket 31, so that the lower end of the fixing rod 32 disengages from one of the mounting holes 2111, which facilitates the movement of the adjusting block 211 and is simple to operate. When the adjusting block 211 moves to the appropriate position, the fixing rod 32 is reset under the action of the first elastic element 33. In this way, the lower end of the fixing rod 32 can be inserted into the corresponding mounting hole 2111, ensuring convenient operation of the locking assembly 30.

[0040] It should be noted that the upper end of the first elastic element 33 is connected to the mounting bracket 31, and this connection includes fixed connection, abutment, etc.

[0041] like Figures 1 to 3 As shown, the locking assembly 30 also includes a handle 34, which includes a pull ring 341 and a connecting rod 342. The connecting rod 342 passes through the upper ends of the pull ring 341 and the fixing rod 32. The lower part of the fixing rod 32 is provided with an annular boss 321, and the lower end of the first elastic member 33 is connected to the annular boss 321. With the above structure, by setting the pull ring 341 and the connecting rod 342, it is convenient to operate the pull ring 341. With the connecting rod 342 passing through the upper ends of the pull ring 341 and the fixing rod 32 in sequence, it is convenient to pull the fixing rod 32 upward by the pull ring 341. The lower end of the fixing rod 32 is provided with an annular boss 321 to ensure that the fixing rod 32 can be easily reset under the action of the first elastic member 33.

[0042] like Figures 1 to 3As shown, a limiting plate 311 is provided on the mounting bracket 31. When the locking assembly 30 is in the clearance position, one side of the pull ring 341 abuts against the side wall of the limiting plate 311, and the other side of the pull ring 341 abuts against the upper surface of the mounting bracket 31 to fix the locking assembly 30 in the clearance position. With the above structure, by providing a limiting plate 311 on the mounting bracket 31, when the locking assembly 30 is in the clearance position, the pull ring 341 can abut against the side wall of the limiting plate 311 and the upper surface of the mounting bracket 31 respectively. This ensures that the pull ring 341 is always in the clearance position, preventing the fixing rod 32 from resetting under the action of the first elastic member 33. The pull ring 341 and the connecting rod 342 are connected at an angle. When the pull ring 341 abuts against the limiting plate 311 and the mounting bracket 31 respectively, the pull ring 341 provides an upward support force to the connecting rod 342, which can ensure that the pull ring 341 will not move downward under the elastic force of the first elastic element 33, thereby improving the structural reliability of the locking assembly 30.

[0043] like Figure 3 As shown, the adjusting block 211 includes a plug-in plate 2112, a roller frame 2113, and a roller 2114. Multiple mounting holes 2111 are spaced apart on the plug-in plate 2112 along its extending direction. The plug-in plate 2112 has a plug-in hole 2115 for accommodating the roller frame 2113. The roller 2114 is rotatably mounted on the roller frame 2113 and rolls in cooperation with the second rotating member 22. With this structure, by providing the plug-in plate 2112, roller frame 2113, and roller 2114, and by providing multiple mounting holes 2111 on the plug-in plate 2112 and a roller frame 2113 at the plug-in hole 2115, the roller frame 2113 can connect to the roller 2114, allowing the roller 2114 to roll in cooperation with the second rotating member 22.

[0044] like Figures 3 to 5As shown, the cable torsion test device also includes a fixed frame 41, a locking block 42, and a second elastic element 43. The fixed frame 41 is mounted on the plug-in plate 2112. The locking block 42 includes a guide rod 421, a locking block 422, and a lever 423. The guide rod 421 is vertically movably mounted on the plug-in plate 2112. The upper end of the guide rod 421 is movably mounted through the fixed frame 41, and the lower end of the guide rod 421 is connected to the locking block 422. The upper surface of the plug-in plate 2112 is provided with a connecting hole. The locking block 422 passes through the connecting hole and engages with the roller frame 2113. The lever 423 is mounted on the side wall of the locking block 422 and is located above the plug-in plate 2112. The second elastic element 43 is sleeved on the outer side wall of the guide rod 421. The upper end of the second elastic element 43 is connected to the fixed frame 41, and the lower end of the second elastic element 43 is connected to the locking block 422. With the above structure, by setting a fixing frame 41, a locking block 42, and a second elastic member 43, the fixing frame 41 is set on the plug plate 2112, and the guide rod 421 in the locking block 42 is movably inserted through the fixing frame 41. The guide rod 421 is connected to the locking block 422. When the guide rod 421 moves upward, it can drive the locking block 422 to separate from the roller frame 2113, which is convenient for disassembling the roller frame 2113. When the guide rod 421 moves downward, it can allow the locking block 422 to pass through the connecting hole to fix the roller frame 2113. The second elastic member 43 is sleeved on the guide rod 421, and thus, under the action of the second elastic member 43, the locking block 42 is reset. The lower end of the second elastic member 43 is connected to the locking block 422, which can ensure the stability of the connection structure between the locking block 422 and the roller frame 2113 under the action of the second elastic member 43.

[0045] In this embodiment, the first rotating component 21 includes a rotating disk 212 with a communicating cavity. One end of the adjusting block 211 is movably inserted into the communicating cavity. The top wall of the rotating disk 212 has a through-hole clearance hole. The locking component 30 passes through the clearance hole and is installed in one of the mounting holes 2111. By setting the rotating disk 212, it is easy to control the rotation of the rotating disk 212, which makes the structure simple. Furthermore, it is easy for the locking component 30 to pass through the clearance hole and engage with the mounting hole 2111 of the adjusting block 211 for easy operation.

[0046] like Figure 1 , Figure 2 , Figure 6 as well as Figure 7As shown, the second rotating component 22 includes a cable bundle 222 and a rotating rod 223. The cable bundle 222 is mounted on the rotating rod 223, which is rotatably mounted on the mounting platform 10 with the center of the cable bundle 222 as its rotation center. The second cable fixing part 221 is mounted on the cable bundle 222. The adjusting block 211 of the first rotating component 21 is slidably connected to the rotating rod 223. With the above structure, by setting the cable bundle 222 and the rotating rod 223, the rotating rod 223 is connected to the cable bundle 222 and rotates with the cable bundle 222 as its rotation center. This facilitates the use of the second cable fixing part 221 on the cable bundle 222 to perform anti-torsion testing on the cable. Furthermore, by slidingly connecting the first rotating component 21 to the rotating rod 223, the rotating rod 223 can drive the cable bundle 222 to rotate when it rotates with the cable bundle 222 as its rotation center, simplifying the driving method.

[0047] like Figure 1 , Figure 2 , Figure 6 as well as Figure 7As shown, the second cable fixing part 221 includes a threaded sleeve 2211, at least two cable fixing blocks 2213, and a third elastic element 2214. The outer wall of the cable bundle 222 is provided with external threads. The internal thread of the threaded sleeve 2211 is threadedly connected to the external thread of the cable bundle 222. The upper end of the threaded sleeve 2211 is provided with a pressing slope 2212. The cross-sectional dimension of the pressing slope 2212 gradually decreases from top to bottom. At least two cable fixing blocks 2213 are provided on the cable bundle 222. Inside 22, the first end of the cable fixing block 2213 extends toward the center of the cable bundle 222, and the second end of the cable fixing block 2213 extends away from the center of the cable bundle 222. The extrusion slope 2212 abuts against the second end of the cable fixing block 2213. The third elastic member 2214 is disposed inside the cable bundle 222. The first end of the third elastic member 2214 is connected to the inner wall of the cable bundle 222, and the second end of the third elastic member 2214 is connected to the cable fixing block 2213. With the above structure, by setting a threaded sleeve 2211, at least two cable fixing blocks 2213, and a third elastic element 2214, the outer wall of the cable bundle 222 is provided with an external thread that can be threadedly connected to the internal thread of the threaded sleeve 2211, allowing the threaded sleeve 2211 to move up and down within the section of the external thread of the cable bundle 222. The upper end of the threaded sleeve 2211 is provided with a pressing inclined surface 2212, which controls the movement of the cable fixing blocks 2213 under the action of the pressing inclined surface 2212 when the threaded sleeve 2211 moves up and down, thus accommodating cables of different diameters. When the cable diameter is small, the threaded sleeve 2211 is controlled to move upwards, allowing the second elastic element 2214 of the cable fixing blocks 2213 to move. The end of the second elastic element 2211 abuts against the extrusion slope 2212, and the first end of the third elastic element 2214 is connected to the inner wall of the cable bundle 222. The second end of the third elastic element 2214 is connected to the cable fixing block 2213. This allows the cable fixing block 2213 to move closer to the cable as the extrusion slope 2212 moves upward and the cross-sectional area gradually decreases. This also allows the third elastic element 2214 to be compressed, thereby pressing the cable. When it is necessary to fix a cable with a larger diameter, the threaded sleeve 2211 only needs to be moved downward. Under the action of the third elastic element 2214, it can play a reset role, thereby ensuring that multiple cables of different diameters can be fixed using the second cable fixing part 221.

[0048] like Figure 2 and Figure 8As shown, an arc-shaped plate 2231 is provided on the rotating rod 223, and an arc-shaped groove 12 is provided on the mounting platform 10. The centers of the arc-shaped plate 2231 and the arc-shaped groove 12 coincide with the rotation center of the cable bundle 222. With the above structure, by providing an arc-shaped plate 2231 on the rotating rod 223 and a corresponding arc-shaped groove 12 on the mounting platform 10, it is convenient for the rotating rod 223 to rotate under the action of the arc-shaped plate 2231.

[0049] like Figure 1 , Figure 2 as well as Figure 8 As shown, the cable torsion testing device also includes a traction rope 51 and a counterweight 52. One end of the traction rope 51 is connected to the end of the rotating rod 223 away from the rotating disk 212, and the other end of the traction rope 51 passes through the mounting platform 10 and is connected to the counterweight 52. With this structure, by setting the traction rope 51 and the counterweight 52, with one end of the traction rope 51 connected to the rotating rod 223 and the other end passing through the mounting platform 10 and connected to the counterweight 52, after the rotating rod 223 is driven to rotate by the first rotating component 21, the first rotating component 21 can rotate in another direction. Under the action of the counterweight 52, the rotating rod 223 can be driven to reset, thus ensuring the structural reliability and practicality of the cable torsion testing device.

[0050] It should be noted that one end of the rotating rod 223 is provided with an installation cylinder, and one end of the traction rope 51 extends into the installation cylinder and is fixedly connected by screws. The traction rope 51 can be threaded through the guide block and guide wheel on the mounting platform 10. The guide block can play a guiding role, and the guide wheel can facilitate movement.

[0051] like Figure 1 and Figure 2 As shown, the mounting platform 10 includes a frame body 13 and a support frame 14. The support frame 14 includes a first plate 141 and a second plate 142. The first plate 141 extends vertically and its lower end is connected to the frame body 13. The second plate 142 extends horizontally and is perpendicular to the first plate 141. The upper end of the first plate 141 is connected to the first end of the second plate 142. A first cable fixing part 11 is provided at the second end of the second plate 142. With the above structure, by setting the frame body 13 and the support frame 14, it is easy to ensure the structural stability of the support frame 14 and ensure that the cable can be fixed by using the first cable fixing part 11 on the second plate 142.

[0052] like Figure 2As shown, the first cable fixing part 11 includes a cable tie ring 111, and the side wall of the cable tie ring 111 is provided with a threaded hole. The cable torsion testing device also includes a cable fastener 53, which passes through the threaded hole. With the above structure, by setting the cable tie ring 111 and using the cable fastener 53 passing through the threaded hole on the cable tie ring 111, it is convenient to use the cable fastener 53 to abut and fix the cable after it passes through the cable tie ring 111, so as to prevent the cable from rotating.

[0053] like Figure 2 As shown, the cable torsion testing device also includes a motor 15, which is mounted on the frame body 13. The motor 15 is driven by the first rotating component 21 to drive the first rotating component 21 to rotate. With the above structure, by setting the motor 15, it is convenient to drive the first rotating component 21 to rotate, ensuring the reliability of the driving method.

[0054] The apparatus provided in this embodiment has the following beneficial effects:

[0055] (1) The first cable fixing part 11 on the mounting platform 10 fixes the cable without rotating, and the cable's torsional resistance can be tested when the second cable fixing part 221 rotates. An adjusting block 211 is provided on the first rotating part 21. The adjusting block 211 is positionally adjustable on the first rotating part 21, allowing for length adjustment. Since the adjusting block 211 is slidably connected to the second rotating part 22, adjusting the length of the adjusting block 211 allows for adjustment of the maximum rotation angle of the second rotating part 22, thereby enabling testing of the cable's torsional resistance at different torsional degrees and improving the accuracy of the cable torsional resistance test.

[0056] (2) When the position of the adjusting block 211 needs to be adjusted, the fixing rod 32 needs to be pulled upward, the first elastic element 33 is compressed, so that the fixing rod 32 moves upward relative to the mounting bracket 31, so that the lower end of the fixing rod 32 disengages from one of the mounting holes 2111, which facilitates the movement of the adjusting block 211 and is simple to operate. When the adjusting block 211 moves to the appropriate position, the fixing rod 32 is reset under the action of the first elastic element 33, so that the lower end of the fixing rod 32 can be inserted into the corresponding mounting hole 2111, ensuring that the operation of the locking assembly 30 is convenient.

[0057] (3) By setting up a plug plate 2112, a roller frame 2113 and a roller 2114, a plurality of mounting holes 2111 are provided on the plug plate 2112, and a roller frame 2113 is provided at the plug hole 2115 of the plug plate 2112. The roller frame 2113 can connect the roller 2114 and enable the roller 2114 to roll with the second rotating member 22.

[0058] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0060] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description.

[0061] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
