[0002] In modern power transmission systems, stranded OPGW optical cables, with their unique structural design and superior performance, not only bear the heavy responsibility of lightning protection for power lines but also shoulder the mission of high-speed and stable communication, making them core equipment for smart grid construction. These optical cables operate in complex natural and electrical environments, enduring multiple challenges such as strong winds, icing, sudden temperature changes, and electrical stresses. Therefore, extremely high requirements are placed on their mechanical properties, especially tensile strength.

The connecting blocks are fixedly installed at the bottom of the elongated blocks, and the tensile gauge is fixedly installed on the two connecting blocks to facilitate the determination of the tensile value.

[0004] However, the aforementioned optical cable tensile testing device has many drawbacks. Its adjustment function is limited, only able to clamp and fix the optical cable in the horizontal direction, making it difficult to adapt to the testing needs of OPGW optical cables of different specifications and structures. It is also inconvenient to simulate tensile forces in different directions, resulting in a lack of accuracy and representativeness in the test results. Furthermore, it is susceptible to external interference during the testing process, leading to large fluctuations in the test results. Utility Model Content

[0026] Example

[0027] Reference Figure 1-4 This embodiment of the present invention provides a tensile testing device for the production of stranded OPGW, comprising:

[0028] The support assembly 100 includes a base 101, a column 102 fixedly connected to the upper end of the base 101, a support member 103 installed on the side wall of the column 102, a connector 104 rotatably installed on the side wall of the support member 103, and a crossbeam 105 fixedly connected to the end of the connector 104.

[0029] The test assembly 200 includes a support rod 201 hinged to the end of the crossbeam 105, a main shaft 202 rotatably connected to the end of the support rod 201, a housing 203 sleeved on the end of the main shaft 202, a pull rod 204 movably inserted into the lower end of the housing 203, an extension rod 205 hinged to the end of the pull rod 204, and a hook 206 hinged to the end of the extension rod 205.

[0030] The base 101 provides a stable support plane for the device. The support member 103 is mounted on the side wall of the column 102, serving as a transition connection. The crossbeam 105 is directionally adjustable at the end of the connector 104 to adapt to different testing requirements. The main shaft 202 is rotatably connected to the end of the support rod 201, allowing the housing 203 to rotate around the main shaft 202 at a certain angle to accommodate different testing needs. The pull rod 204 is movably inserted into the lower end of the housing 203, with one end capable of moving up and down within the housing 203. The extension rod 205 is hinged to the end of the pull rod 204, and the hook 206 is hinged to the end of the extension rod 205, used to fix the OPGW optical cable to be tested for tensile testing.

[0031] Specifically, the test assembly 200 also includes a main cylinder 207 fixedly connected inside the housing 203. The output end of the main cylinder 207 passes through the top of the housing 203, and the upper end of the main cylinder 207 is fixedly connected to the upper side wall of the spindle 202. The test assembly 200 also includes an auxiliary cylinder 208 fixedly connected to the side wall of the main cylinder 207. The output end of the auxiliary cylinder 208 is fixedly connected to the end of the pull rod 204.

[0032] When the main cylinder 207 operates, its output thrust or pull force can drive the main shaft 202 and its connected components to perform corresponding movements. The auxiliary cylinder 208 is fixedly connected to the side wall of the main cylinder 207, and its output end is fixedly connected to the end of the pull rod 204. The auxiliary cylinder 208 can independently control the up and down movement of the pull rod 204 within the housing 203, achieving precise control over the position of the hook 206 and the method of applying the pull force.

[0033] Furthermore, the test assembly 200 also includes a slider 209 fixedly connected to the side wall of the main cylinder 207, and the slider 209 is slidably engaged with the side wall of the main shaft 202.

[0034] The slider 209 is used to guide the movement direction of the main cylinder 207, ensuring its stability during operation and reducing errors caused by movement deviations.

[0035] Preferably, handles are symmetrically installed on the outer side wall of the housing 203, and a push rod is installed inside the housing 203 and is fixedly connected to the end side wall of the main cylinder 207.

[0036] Handles are symmetrically installed on the outer side wall of the housing 203 to facilitate the movement and adjustment of the device by the operator. The push rod is installed inside the housing 203 and is fixedly connected to the end side wall of the main cylinder 207, which can further enhance the stability of the main cylinder 207 during operation.

[0037] It should be noted that the test assembly 200 also includes a handle bolt 210 threaded to the side wall of the pull rod 204, with the end of the handle bolt 210 threaded to the side wall of the extension rod 205.

[0038] By rotating the handle bolt 210, the relative position between the extension rod 205 and the pull rod 204 can be adjusted, thereby enabling fine-tuning of the angle and position of the hook 206.

[0039] Preferably, the end of the support rod 201 is equipped with a mounting structure that works in conjunction with the spindle 202, and the side wall of the end of the support rod 201 is equipped with bolts that are fixedly connected to the side wall of the spindle 202.

[0040] Bolts are installed on the end side wall of the support rod 201 to ensure the stability of the connection between the main shaft 202 and the support rod 201.

[0041] During operation, the operator first adjusts the angle of the crossbeam 105 by rotating the connector 104, according to the specifications and testing requirements of the OPGW optical cable to be tested, so that the test assembly 200 is in the appropriate position. Then, the operator holds the handle on the outer wall of the housing 203 and fixes the OPGW optical cable to be tested with the hook 206. The main cylinder 207 is activated, outputting thrust or pull force, which drives the main shaft 202 and the connected housing 203, pull rod 204, extension rod 205, and hook 206 to move accordingly, thereby applying tension to the OPGW optical cable. During this process, the slider 209 slides along the side wall of the main shaft 202 to ensure smooth movement of the main cylinder 207. At the same time, the auxiliary cylinder 208 is activated according to the actual testing requirements. When the auxiliary cylinder 208 is working, its output end pushes the pull rod 204 to move up and down inside the housing 203, further adjusting the magnitude and direction of the tension applied to the OPGW optical cable by the hook 206. During the application of tension, the operator can fine-tune the relative position between the extension rod 205 and the pull rod 204 by rotating the handle bolt 210, thereby achieving precise control over the angle and position of the hook 206 to ensure the accuracy of the tension detection.

[0042] In summary, this device, through the coordinated operation of the main cylinder 207 and the auxiliary cylinder 208, can precisely control the magnitude and direction of the tensile force applied to the OPGW optical cable. Simultaneously, the design of the handle bolt 210 allows the operator to fine-tune the angle and position of the hook 206, effectively improving the accuracy of tensile force detection. The adjustable design of the support assembly 100 and the flexible connection methods between the components of the testing assembly 200 enable the device to adapt to the tensile force testing needs of OPGW optical cables of different specifications and shapes, greatly improving the device's versatility and adaptability. The handle design on the outer wall of the housing 203 facilitates the operator's movement and adjustment of the device. Furthermore, the device is mainly operated via cylinders and the handle bolt, making operation simple and easy to understand, reducing the operator's workload and improving testing efficiency.
