Description

Technical Field

[0001] This utility model relates to the field of tensile strength testing technology, and in particular to a device for testing the tensile strength of utility poles. Background Technology

[0002] In the field of power engineering, utility poles, as core supporting components of power transmission networks, have tensile strength that directly affects the operational safety and stability of the power system. Therefore, tensile strength testing is a crucial step in scenarios such as factory quality inspections and safety checks of aging utility poles. However, current mainstream methods for testing the tensile strength of utility poles still have many technical limitations and operational constraints, making it difficult to meet the demands for efficient, accurate, and safe testing. Traditional testing methods generally rely on manual operation to apply tension, such as manually rotating winches, pulling ropes, or using simple hydraulic equipment. This not only requires a large investment of manpower, but also makes it difficult to accurately control the speed and force of the applied tension. Sudden increases or decreases in tension can easily occur, potentially causing the utility pole to break prematurely due to sudden changes in stress, making it impossible to accurately obtain the ultimate tensile strength data. Unstable stress can also lead to safety hazards such as the utility pole collapsing or parts falling off, posing a threat to the personal safety of workers. Summary of the Invention

[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a device for testing the tensile strength of utility poles. This solves the problems that require a lot of manpower to manually rotate the winch, manually pull the rope or use simple hydraulic equipment to apply force, and that it is difficult to accurately control the speed and force of the applied force during the manual application process, which can easily lead to sudden increases or decreases in the tensile force.

[0004] This utility model also provides a utility pole tensile strength testing device, which significantly reduces manual operation. The motor replaces manual labor to apply the tension, and the tension sensor directly outputs real-time tension data. Workers do not need to manually measure the tension; they only need to observe the changes in the appearance of the utility pole and the deformation value of the scale. This simplifies the operation process and shortens the testing time for a single utility pole. Furthermore, the device has a simple structure and clear connection method for each component, making subsequent maintenance and repair less difficult. This further reduces long-term operating costs and improves the overall testing efficiency.

The device includes a fixed plate with a fixed pull ring fixedly connected to its upper surface. A tension rope is fixedly connected to the upper surface of the pull ring, and the other end of the tension rope is fixedly connected to a fixed sleeve. These components significantly reduce manual operation. A motor replaces manual labor in applying tension, and a tension sensor directly outputs real-time tension data. Workers no longer need to manually measure the tension; they only need to observe changes in the appearance of the utility pole and the deflection of the scale. This simplifies the operation process and shortens the inspection time for a single utility pole. Furthermore, the device's components have simple structures and clear connections, resulting in lower maintenance and repair difficulties, further reducing long-term operating costs and improving overall inspection efficiency.

Furthermore, the simple structure and clear connection method of each component of the device make subsequent maintenance and repair less difficult, further reducing long-term operating costs and improving the overall efficiency of the inspection work.

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] Reference Figure 1-4This utility model discloses a device for testing the tensile strength of a utility pole, comprising: a utility pole mechanical testing platform 1, a support leg 2 fixedly connected to the lower surface of the utility pole mechanical testing platform 1, a base 3 fixedly connected to the lower surface of the support leg 2, a flexible plate made of rubber on the lower surface of the base 3, a fixing block 4 fixedly connected to the upper surface of the utility pole mechanical testing platform 1, a fixing frame 18 fixedly connected to the side surface of the fixing block 4, and a fixing member 15 fixedly connected to the side surface of the fixing frame 18. There are two fixing frames 18 and two fixing members 15. The fixing member 15 is provided with a threaded hole 16, and a bolt 17 is threadedly connected to the inner surface of the threaded hole 16. A utility pole 14 is provided on the inner surface of the fixing member 15, and a fixing sleeve 12 is detachably fixedly installed on the outer surface of the utility pole 14.

[0017] Specifically: The utility pole 14 to be tested is placed inside the fixing parts 15 of the two fixing brackets 18. Bolts 17 are screwed in through the threaded holes 16 on the fixing parts 15. The clamping action of the bolts 17 firmly clamps the utility pole 14 in the fixing parts 15. At the same time, the silicone anti-slip pad and anti-slip texture on the inner surface of the fixing parts 15 can increase the friction with the utility pole 14, preventing the utility pole 14 from shifting or slipping during the test. Fixing sleeves 12 are then placed on the designated test position of the utility pole 14.

[0018] The upper surface of the pole mechanical testing platform 1 is provided with a slide rail 5. A slider 8 is slidably connected to the inner surface of the slide rail 5. A lead screw 7 is threadedly connected to the inner surface of the slider 8. A motor 6 is fixedly connected to the side surface of the slide rail 5. The output end of the motor 6 passes through the interior of the slide rail 5. The lead screw 7 is driven by the motor 6. A fixing plate 9 is provided on the upper surface of the slider 8. A fixing pull ring 10 is fixedly connected to the upper surface of the fixing plate 9. A tension rope 11 is fixedly connected to the upper surface of the fixing pull ring 10. The other end of the tension rope 11 is fixedly connected to the fixing sleeve 12. A tension sensor is provided on the tension rope 11. An anti-slip pad is provided on the inner surface of the fixing sleeve 12. The anti-slip pad is made of silicone and has anti-slip texture on its outer surface. A scale 13 is provided on the upper surface of the pole mechanical testing platform 1. The scale 13 is located directly below the pole 14.

[0019] Specifically: the fixed sleeve 12 is fixedly connected to one end of the tension rope 11, and the other end of the tension rope 11 is connected to the fixed pull ring 10 on the slider 8, completing the connection of the force-bearing structure. Then, the device is started to apply tension, and the motor 6 on the side surface of the slide rail 5 is turned on. The output end of the motor 6 drives the lead screw 7 inside the slide rail 5 to rotate. The inner surface of the slider 8 is threadedly connected to the lead screw 7. The rotation of the lead screw 7 is converted into linear motion of the slider 8 along the length of the slide rail 5. The movement of the slider 8 applies a horizontal tension to the fixed sleeve 12 through the fixed pull ring 10 and the tension rope 11. This tension is further transmitted to the detection part of the utility pole 14. The system gradually applies tensile load to the utility pole 14, simultaneously monitoring and recording data. A tension sensor installed on the tension rope 11 collects the current tension value applied to the pole 14 in real time, which can be read by the sensor's display device. Simultaneously, the system observes changes in the pole's appearance and measures the deformation displacement under tension using a scale 13 located directly below the pole on the pole's mechanical testing platform 1. This helps determine if cracks, fractures, or other failures have occurred. Finally, the tensile strength of the pole is assessed based on the test data. When significant failure occurs, the tension value recorded by the tension sensor represents the pole's ultimate tensile strength. To test the pole's performance under a specified tension, the motor 6 can be stopped, maintaining the current tension for a period. The stability of the deformation is observed using the scale 13, allowing for an assessment of the pole's tensile stability and load-bearing capacity, thus completing the tensile strength testing process.

[0020] Working principle: The utility pole 14 to be tested is placed inside the fixing parts 15 of the two fixing brackets 18. Bolts 17 are screwed into the threaded holes 16 on the fixing parts 15. The clamping action of the bolts 17 firmly clamps the utility pole 14 in the fixing parts 15. At the same time, the silicone anti-slip pad and anti-slip texture on the inner surface of the fixing parts 15 can increase the friction with the utility pole 14, preventing the utility pole 14 from shifting or slipping during the test. The fixing sleeve 12 is put on the designated test position of the utility pole 14. The fixing sleeve 12 is fixedly connected to one end of the tension rope 11, and the other end of the tension rope 11 is connected to the fixing pull ring 10 on the slider 8, completing the connection of the force-bearing structure. Then, the device is started to apply tension. The motor 6 on the side surface of the slide rail 5 is turned on. The output end of the motor 6 drives the lead screw 7 inside the slide rail 5 to rotate. The inner surface of the slider 8 is threadedly connected to the lead screw 7. The rotation of 7 is converted into linear motion of slider 8 along the length of slide rail 5. The movement of slider 8 applies horizontal tension to fixed sleeve 12 through fixed pull ring 10 and tension rope 11. This tension is further transmitted to the detection part of utility pole 14, realizing the gradual application of tensile load on utility pole 14. Data monitoring and recording are carried out simultaneously during the application of tension. The tension sensor installed on tension rope 11 will collect the current tension value applied to utility pole 14 in real time. The staff can read the tension data through the sensor's matching display device. At the same time, the appearance changes of utility pole 14 are observed, and the deformation displacement of utility pole 14 under tension is measured by combining the scale 13 located directly below utility pole 14 on the utility pole mechanical testing platform 1. This determines whether utility pole 14 has cracks, fractures or other failure phenomena. Finally, the utility pole 14 is judged based on the test data. The tensile strength is measured by the force sensor. When the pole 14 shows obvious failure, the tensile force value recorded by the force sensor is the ultimate tensile strength of the pole 14. If it is necessary to test the performance of the pole 14 under a specified tensile force, the motor 6 can be stopped and the current tensile force can be maintained for a period of time. The deformation can be observed through the scale 13 to determine whether it is stable, thereby evaluating the tensile stability and load-bearing capacity of the pole 14 and completing the entire tensile strength test process.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
