Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, and in particular to a low-smoke halogen-free flame-retardant cable material process testing machine. Background Technology

[0002] Cables are widely used in modern power transmission and signal conduction, serving as a critical infrastructure for ensuring the stable operation of power systems and communication networks. Low-smoke halogen-free flame-retardant cable materials, as core materials for manufacturing high-performance cables, have their processing performance directly affecting the cable's safety, durability, and reliability. Therefore, performance testing of these cable materials is particularly important.

[0003] In practical use, cables face a variety of complex operating conditions. On the one hand, when cables are connected and installed between utility poles and towers, they deform due to their own weight and need to withstand a certain amount of tension. On the other hand, wind can cause cables to sway, and sunlight and changes in ambient temperature can also affect cable performance. These actual operating conditions place high demands on the performance of cable materials, requiring simulation and testing.

[0004] However, existing cable material testing equipment often has limited functionality and cannot fully simulate the complex operating conditions of cables in actual use. Some equipment can only perform single tensile tests or environmental simulation tests, failing to consider multiple influencing factors comprehensively. This leads to significant deviations between test results and actual usage conditions, making it difficult to accurately evaluate the process performance of low-smoke halogen-free flame-retardant cable materials and failing to provide comprehensive and reliable data support for the research and development and production of cable materials. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a low-smoke halogen-free flame-retardant cable material process testing machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A low-smoke halogen-free flame-retardant cable material process testing machine includes a U-shaped base. The inner walls at both ends of the upper part of the U-shaped base are equipped with fixing clamps, each clamp holding the same cable. A horizontal frame is provided at the top of the cable at its middle position, with support rods at both ends. Baffles are symmetrically fitted on the outer periphery of the frame, and the cable is slidably inserted into the gaps between the baffles. A connecting rod is provided at the bottom of the support rod, and a pressure adjusting component for applying pressure to the cable is provided at the bottom of the connecting rod. Guide rails are symmetrically provided on the bottom wall of the U-shaped base, and a drive component for controlling cable swaying is provided at the top of the guide rails.

[0008] Through the above technical solutions, the coordinated arrangement of structures such as U-shaped seats, fixing clamps, crossbars, support rods, baffles, connecting rods, pressure adjustment components, and drive components enables the simulation testing of cables under various complex working conditions, including deformation simulation caused by their own gravity and wind-blown swaying simulation, thus comprehensively testing the performance of cable materials.

[0009] Preferably, the pressure regulating assembly includes a pull rod located at the bottom of the connecting rod, a seat plate slidably fitted on the lower part of the pull rod, a bracket at the bottom of the seat plate, a screw rotatably connected to the bottom of the seat plate, a connecting seat threaded onto the screw, a tension gauge at one end of the connecting seat, the tension gauge being connected to the pull rod, a guide rod vertically and symmetrically slidably inserted into the connecting seat, the guide rod being fixed to the bottom of the seat plate, and a handwheel coaxially provided at the bottom end of the screw.

[0010] Through the above technical solutions, the pressure adjustment component can adjust the pressure applied to the cable by rotating the handwheel, screw, connecting seat and other components. The tension gauge can display the pressure value in real time, which is convenient for accurate control and recording of the pressure, thereby accurately testing the cable material's ability to withstand its own weight deformation.

[0011] Preferably, the drive assembly includes a slide block slidably mounted on the top of the guide rail, a lead screw at the end of the slide block, and a servo motor coaxially mounted at the end of the lead screw.

[0012] The above technical solution involves a servo motor driving a lead screw to rotate, which in turn causes the slide to move on the guide rail, thereby causing the cable to swing. This simulates the actual situation of the cable being blown by the wind in nature and tests the performance of the cable material under dynamic swing conditions.

[0013] Furthermore, an ultraviolet lamp is installed on the top of the U-shaped base.

[0014] Through the above technical solutions, the ultraviolet lamp installed on the top of the U-shaped seat can simulate the solar radiation environment and detect the performance changes of cable materials under ultraviolet radiation, further enriching the simulation of the cable's operating environment.

[0015] Furthermore, a hot air blower is also installed on the upper inner wall of the U-shaped seat.

[0016] Through the above technical solutions, the hot air blower on the upper inner wall of the U-shaped seat can blow out winds of different temperatures to simulate winds of different temperatures in nature. Combined with ultraviolet lamps, it can more comprehensively and realistically simulate the usage of cables in actual climatic environments, thereby improving the accuracy of testing.

[0017] Preferably, a camera is also installed on the top of the U-shaped base.

[0018] Through the above technical solutions, the camera on top of the U-shaped base can record the deformation or breakage process of the cable throughout the entire test, providing intuitive and comprehensive image data for the test personnel to analyze the cable material performance in the future, which helps to accurately evaluate the cable material's process performance.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. Multi-dimensional working condition simulation: The pressure regulating component simulates the deformation caused by the cable's own weight, and the driving component simulates the swinging of the wind, realizing multi-dimensional simulation of the mechanical working conditions of the cable during actual installation and use. It can comprehensively test the performance of the cable material under dynamic and static stress.

[0021] 2. When combined with a hot air blower, ultraviolet lamps can simulate solar radiation and natural winds at different temperatures, creating diverse climatic environments to accurately test the weather resistance of cable materials under ultraviolet radiation and temperature changes, thereby improving the consistency between test results and actual application scenarios.

[0022] 3. The camera records the cable deformation or breakage process in real time, providing intuitive image data for test analysis, facilitating accurate evaluation of the cable material's process performance, providing reliable data support for research and development and production, and improving the scientific nature and traceability of the test.

In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example 1, referring to Figures 1 to 4 A low-smoke halogen-free flame-retardant cable material process testing machine includes a U-shaped base 1. The inner walls of both ends of the upper part of the U-shaped base 1 are provided with fixing clamps 2, and the fixing clamps 2 are fixed with the same cable 3. A horizontal frame 4 is provided at the top of the middle position of the cable 3. Support rods 5 are provided at both ends of the horizontal frame 4. Baffles 22 are symmetrically sleeved on the outer periphery of the horizontal frame 4. The cable 3 is slidably inserted into the gap of the baffles 22. The bottom of the support rods 5 is provided with the same connecting rod 6. The bottom of the connecting rod 6 is provided with a pressure adjustment component for applying pressure to the cable 3. The bottom wall of the U-shaped base 1 is symmetrically provided with guide rails 16. The top of the guide rails 16 is provided with a drive component for controlling the swaying of the cable 3.

[0031] In this embodiment, the pressure regulating component includes a pull rod 7 located at the bottom of the connecting rod 6, a seat plate 9 slidably mounted on the lower part of the pull rod 7, a bracket 8 at the bottom of the seat plate 9, a screw 10 rotatably connected to the bottom of the seat plate 9, a connecting seat 11 threadedly mounted on the screw 10, a tension gauge 13 at one end of the connecting seat 11, the tension gauge 13 being connected to the pull rod 7, a guide rod 12 vertically and symmetrically slidably inserted into the connecting seat 11, the guide rod 12 being fixed to the bottom of the seat plate 9, a handwheel 14 coaxially mounted at the bottom end of the screw 10, and a drive component including a slide seat 15 slidably mounted on the top of the guide rail 16, a lead screw 17 at the end of the slide seat 15, a servo motor 18 coaxially mounted at the end of the lead screw 17, an ultraviolet lamp 21 at the top of the U-shaped seat 1, a hot air blower 19 on the upper inner wall of the U-shaped seat 1, and a camera 20 at the top of the U-shaped seat 1.

[0032] The working principle of this embodiment:

[0033] The fixing clamps on the inner walls of both ends of the upper part of the U-shaped bracket fix the cable, placing it in the designated position of the test device and providing a stable test object for subsequent tests.

[0034] Rotating the handwheel drives the screw to rotate. Because the connecting seat is threaded into the screw and the guide rod restricts the rotation of the connecting seat, it moves up and down along the guide rod. The connecting seat is connected to the pull rod via a tension gauge, which in turn moves the pull rod up and down, applying different levels of pressure to the cable. This simulates the deformation caused by the cable's own weight during installation between utility poles. The tension gauge displays the pressure value, facilitating recording and control, thereby testing the maximum cracking resistance of the cable material.

[0035] A servo motor drives a lead screw to rotate, which in turn drives a slide to reciprocate horizontally on a guide rail. The slide is connected to a cable, which in turn causes the cable to swing left and right, simulating the swaying of the cable caused by wind in nature, in order to test the performance of the cable material under dynamic stress.

[0036] The ultraviolet lamp at the top of the U-shaped base emits ultraviolet light to simulate sunlight, allowing for testing of cable material performance changes under ultraviolet radiation. The hot air blower can blow air at different temperatures to simulate natural wind temperatures. Combined with the ultraviolet lamp, this provides a more comprehensive simulation of the cable's operating environment under different climatic conditions, enabling testing of the cable material's performance at varying temperatures.

[0037] The camera on top of the U-shaped base is used to record the deformation or breakage of the cable throughout the test, which facilitates subsequent observation and analysis by the test personnel and provides intuitive image data for evaluating the process performance of the cable material.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
