Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1-5 As shown, a steel pole wind resistance strength testing device includes a main body 1. A movable testing component 2 is provided on one side of the main body 1. The movable testing component 2 includes a fixed testing component 3 for testing and a lifting adjustment component 4 for adjusting the height. The fixed testing component 3 includes a mounting base 21. Several fixed bearings 23 are fixedly installed on the top of the mounting base 21. Two rotating shafts 24 are respectively inserted through and movably installed on the several fixed bearings 23. Each rotating shaft 24 inserts two fixed bearings 23. A clamping plate 25 and a crank 26 are respectively inserted through and fixedly installed on the two rotating shafts 24. A piston rod 28 is respectively hinged to one end of the two cranks 26. The piston rod 28 is movably installed on the output end of a hydraulic cylinder 27. One side of the hydraulic cylinder 27 is hinged to one side of the mounting base 21. A force sensor 22 is fixedly installed at the bottom of the mounting base 21. A steel rod 29 is placed on the top of the force sensor 22. A displacement sensor 30 is detachably installed in the middle and top of the steel rod 29.

[0026] During operation, the steel rod 29 is placed on top of the force sensor 22, and then the hydraulic cylinder 27 is driven to extend and retract the piston rod 28 at the output end. One end of the piston rod 28 is hinged to the crank 26, which drives the rotating shaft 24 to rotate, thereby causing the rotating shaft 24 to drive the clamping plate 25 to rotate accordingly. The two clamping plates 25 are used to clamp and fix the two sides of the steel rod 29. Then, the force sensor 22 and the displacement sensor 30 are used to test the strength of the steel rod 29.

[0027] Furthermore, the main body 1 includes a fixed platform 11, a support base 12 is fixedly installed on the top of the fixed platform 11, and a fan 13 is fixedly installed on the top of the support base 12.

[0028] During operation, the support base 12 and the fan 13 are fixed by the installation of the fixed platform 11, which generates corresponding support and ensures the stability of the fan 13 during operation.

[0029] Furthermore, the lifting adjustment component 4 includes a base 31, a servo motor 32 is fixedly installed on the top of the base 31, a first sprocket 33 is fixedly installed at the output end of the servo motor 32, a transmission chain 34 is meshed around the first sprocket 33, and a second sprocket 35 is meshed on the other side of the transmission chain 34.

[0030] During operation, the servo motor 32 is fixed by the base 31. When the servo motor 32 is driven to work, the first sprocket 33 at the output end rotates. The rotational motion is transmitted to the movable shaft 36 through the meshing between the first sprocket 33, the transmission chain 34 and the second sprocket 35.

[0031] Furthermore, the lifting adjustment component 4 also includes a movable shaft 36, one end of which is connected and fixedly mounted with a second sprocket 35, and both ends of the movable shaft 36 are movably mounted in the bearing seats at the top of the base 31. The movable shaft 36 is connected and fixedly mounted with two third sprockets 37.

[0032] During operation, both third sprockets 37 are engaged with adjusting chains 38. The second sprocket 35 drives the movable shaft 36 to rotate, so that the third sprocket 37 on the movable shaft 36 engages with the adjusting chain 38, thereby enabling the adjustment chain 38 to move.

[0033] Furthermore, the lifting adjustment component 4 also includes a lifting platform 39, an adjustment chain 38 is fixedly installed on the top of the lifting platform 39, a counterweight 42 is fixedly installed on the other end of the adjustment chain 38, a sliding groove is opened on the top of the base 31, and the counterweight 42 is slidably embedded in the sliding groove on both sides.

[0034] During operation, when the adjusting chain 38 rotates, one end of the adjusting chain 38 drives the lifting platform 39 to rise and fall, while the counterweight 42 at the other end of the adjusting chain 38 ensures the meshing between the third sprocket 37 and the adjusting chain 38.

[0035] Furthermore, two limit rods 41 are installed through and movable on one side of the lifting platform 39. The two limit rods 41 are fixedly installed on the top of the base 31, and the top of the lifting platform 39 is fixedly installed with a mounting base 21.

[0036] During operation, when the lifting platform 39 is raised or lowered, the adjusting chain 38 supports the lifting platform 39, which may cause the lifting platform 39 to be unstable during the movement. The installation of the limit rod 41 limits the lifting platform 39 to ensure that the lifting platform 39 drives the mounting base 21 to rise and fall vertically.

[0037] Working principle: The steel rod 29 is placed on the force sensor 22, and then the displacement sensor 30 is installed at the top and middle of the steel rod 29. The steel rod 29 is fixed by the clamping plate 25 driven by the hydraulic cylinder 27. According to the actual installation height of the steel rod 29, the servo motor 32 is started. Through the transmission of the first sprocket 33, the transmission chain 34, the second sprocket 35, the movable shaft 36 and the third sprocket 37, the adjusting chain 38 is driven to pull the lifting platform 39 up and down. The mounting seat 21 of the fixed steel rod 29 is adjusted to the required detection height. The limit rod 41 ensures that the lifting process is stable and vertical. The fan 13 is started to simulate different wind environments. The steel rod 29 is subjected to force and displacement under the action of wind. The force sensor 22 detects the wind load on the steel rod 29 in real time, and the displacement sensor 30 detects the displacement of the middle and top of the steel rod 29. The detected data is transmitted to the control system for analysis to evaluate whether the wind resistance of the steel rod 29 meets the requirements.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
