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 protection scope of the present utility model.

[0025] Example 1:

[0026] like Figures 1-4 As shown, an impact resistance testing device for high-strength square tubes according to an embodiment of the present invention includes a test platform 1, a protective mechanism 2 above the test platform 1, a protective frame 201 fixedly mounted above the test platform 1, a hydraulic telescopic rod 202 mounted on the protective frame 201, an mounting plate 203 fixedly mounted on one end of the hydraulic telescopic rod 202, and two protective shielding plates 204 fixedly mounted above the mounting plate 203 for shielding debris generated during impact of the high-strength square tubes. A protective groove 8 is provided above the test platform 1, the inner wall of the protective groove 8 is opposite to one end of the protective shielding plate 204, and one end of the protective shielding plate 204 penetrates through the protective frame 201.

[0027] An auxiliary mechanism 3 is provided below the mounting plate 203. The auxiliary mechanism 3 includes two spring-loaded telescopic rods 301 fixedly installed below the mounting plate 203. Each spring-loaded telescopic rod 301 consists of a telescopic rod one (small diameter), a telescopic rod two (large diameter), and their springs. One end of the telescopic rod one is nested and connected to the inner wall of the telescopic rod two through a sealing block or sealing gasket. The spring is fitted outside the telescopic rod one and the telescopic rod two. An auxiliary pressing plate 302 is fixed to one end of the two spring-loaded telescopic rods 301 for auxiliary pressing of the high-strength square tube. An impact test hammer 303 is fixed below the mounting plate 203. The impact test hammer 303 has a mounting hole, and an acceleration sensor 7 is installed on the inner wall of the mounting hole for measuring the acceleration change of the impact hammer or the sample. The impact test hammer 303 is located between the auxiliary pressing plates 302.

[0028] Example 2:

[0029] like Figures 1-4 As shown, according to an embodiment of the present invention, an impact resistance testing device for high-strength square tubes is provided above the test platform 1. The fixing mechanism 4 includes a placement platform 401 fixedly installed above the test platform 1 for assisting in the placement of the test piece. Three placement holes are opened above the placement platform 401. The number of placement holes can be increased or decreased according to the actual situation. A pressure sensor 6 is installed on the inner wall of the placement hole for measuring the impact force applied to the high-strength square tube.

[0030] Two fixed seats 402 are fixedly installed on the top of the test bench 1. The top of the two fixed seats 402 is opposite to the position of the auxiliary pressing plate 302. Two electric telescopic rods 403 are installed on the opposite side of the two fixed seats 402. One end of the electric telescopic rod 403 is provided with a clamping plate 404 for clamping and fixing the high-strength square tube. A protective pad 5 is installed on one side of the clamping plate 404, and the protective pad 5 is adapted to one side of the clamping plate 404.

[0031] The electric telescopic pole 403, pressure sensor 6, and acceleration sensor 7 are electrically connected to a controller during actual use. The controller, electric telescopic pole 403, pressure sensor 6, and acceleration sensor 7 are electrically connected to an external power supply.

[0032] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0033] In summary, with the help of the above-mentioned technical solution of this utility model, during the test, the staff places the high-strength square tube to be tested on the placement platform 401 on the test platform 1, and ensures that the square tube is in stable contact with the platform surface through the pressure sensor 6 in the placement hole. After placement, the staff starts the electric telescopic rod 403, which pushes the clamping plate 404 to move towards the square tube. The protective pad 5 on the inner side of the clamping plate 404 fits against the surface of the square tube, providing anti-slip clamping force and preventing the square tube from shifting during the test.

[0034] After fixing, the staff starts the hydraulic telescopic rod 202, which drives the mounting plate 203 to descend. At the same time, the mounting plate 203 drives the protective shield 204 to extend downward along the protective frame 201 until the end of the mounting plate 203 is inserted into the protective groove 8 of the test bench 1, forming a closed protective area to block the flying debris generated during the impact test.

[0035] Simultaneously, the spring-loaded telescopic rod 301 below the mounting plate 203 descends synchronously with the hydraulic telescopic rod 202, while the lower part of the auxiliary pressing plate 302 contacts the upper part of the fixed base 402 and the surface of the square tube, further stabilizing the position of the square tube and eliminating any possible small gaps before testing. After the impact test hammer 303 descends to the preset height with the mounting plate 203, it is quickly released by the hydraulic system, applying a vertical impact force to the square tube. During the impact, the acceleration sensor 7 records the acceleration change of the impact test hammer 303 in real time to evaluate the impact energy.

[0036] The pressure sensor 6 installed on the placement platform 401 measures the force transmitted to the platform when the square tube is impacted, and is used to calculate the impact resistance of the square tube. After the test is completed, the hydraulic telescopic rod 202 drives the mounting plate 203 to rise, the protective shield 204 retracts the protective frame 201, and the auxiliary pressing plate 302 and clamping plate 404 release the fixation of the square tube.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
