Description

Technical Field

[0001] This utility model belongs to the field of testing device technology, specifically relating to a guardrail impact resistance testing system. Background Technology

[0002] Guardrails are important auxiliary components in buildings, structures, and bridges. While they do not affect the load-bearing performance of the main structure, they are crucial to the safety of users. The safety acceptance of guardrails requires impact resistance testing. Currently, the traditional testing method involves setting a suspension point directly above the test point on the guardrail and suspending a shotgun bag above it. During the test, the suspension height is adjusted, and the shotgun bag is manually pulled backward to a certain angle before being released, causing the shotgun bag to impact the guardrail with a certain amount of energy. Throughout this process, holes need to be drilled and expansion bolts driven into the crossbeam directly above the guardrail. If there is no usable building above, an additional hanging steel frame needs to be erected. Currently, the traditional testing method has the following four drawbacks:

[0003] (1) The entire testing process requires manual operation, resulting in low testing efficiency;

[0004] (2) Hanging shotgun bags requires destroying buildings;

[0005] (3) When additional steel frames need to be erected, the operation is troublesome, the inspection process takes a long time, and there are significant operational risks to the safety of the inspection personnel.

[0006] (4) The impact energy of the suspended shot bag is difficult to control, and the detection data error is too large.

[0007] Therefore, it can be seen that there is currently a lack of a reliable and durable testing system for the impact resistance of guardrails, so that people can easily test the impact resistance of guardrails.

[0008] Therefore, a new technology is needed to address the lack of a reliable and durable system for testing the impact resistance of guardrails in existing technologies. Utility Model Content

[0059] Reference Figures 1 to 5 In one embodiment, the testing method of the present invention "a guardrail impact resistance testing system 1" includes the following steps:

[0060] S1. Before testing, mark the position to be tested on guardrail 6;

[0061] S2. During use, transport the "Guardrail Impact Resistance Testing System 1" to the testing area, connect the host system 4 to the servo motor with the data transmission cable 41, and connect the host system 4 to the main control device F with the connecting wire 42. Turn on the host system 4 and conduct an air impact test (to avoid test errors). After confirming that there are no problems with use, push the "Guardrail Impact Resistance Testing System 1" to the front of the building guardrail 6 and use the clamping device 26 to clamp the moving wheel 25.

[0062] Then, rotate the support member 241, causing the support member 241 to lift the entire support structure 2 and the moving wheel 25, and then use the locking member 242 to lock the load-bearing plate 21 onto the support member 241.

[0063] Next, adjust the telescopic outriggers of the adjustable height main frame assembly so that the front impact point of the impact head 321 corresponds to the detection position of the building guardrail 6. After the correspondence is correct, lock the telescopic outriggers onto the fixed outriggers using the buckles.

[0064] Afterwards, input the data to be tested into the host system 4, adjust the impact level, and start the power storage button of the host system 4. The servo motor starts and adjusts the electric telescopic device 332 to the baffle C at the front end of the elastic telescopic component by adjusting the retraction position of the telescopic rod E.

[0065] Then, the electric telescopic device 332 is activated, and the telescopic part G extends to limit the baffle C.

[0066] Afterwards, the servo motor continues to drive the telescopic rod E to retract, and the telescopic part G compresses the elastic telescopic component 333 through the baffle, causing the elastic telescopic component 333 to reach the set impact energy and achieve successful energy storage.

[0067] Afterwards, the limiting effect of the telescopic part G on the baffle C is released, and the elastic force of the elastic telescopic part 333 is released, pushing the impact head 321 to impact the building railing 6. After the impact head 321 impacts the railing 6, it needs to be retrieved in time to avoid secondary impact between the impact head 321 and the building railing 6.

[0068] S3. After impacting the building guardrail 6, observe the state of the building guardrail 6 and record the impact data values.

[0069] S4. After the test is completed, shut down the host system 4, disconnect the data transmission cable 41 connecting the host system 4 to the servo motor, disconnect the connecting wire 42 connecting the host system 4 to the main control device F, lower the telescopic legs of the adjustable height main frame assembly, and lock them with the buckles; then, release the locking action of the locking piece 242, and rotate the support piece 241 to restore the support piece 241 and the locking piece 242 to their original state; then, release the rotation restriction of the clamping device 26 on the moving wheel 25, and remove the "Guardrail Impact Resistance Testing System 1" from the site.

[0070] The present invention, “A guardrail impact resistance testing system”, is simple to operate, highly adaptable, and can be set according to different building guardrail types and heights, thus meeting the testing needs of various building guardrail models.
