Description

Technical Field

[0001] This utility model relates to the field of traffic engineering guardrail strength testing technology, specifically to a traffic engineering guardrail strength testing device. Background Technology

[0002] Guardrails play a crucial role in traffic engineering, separating traffic flows from different directions, preventing vehicles from running off the road, and protecting pedestrian safety. Guardrail strength testing is a key step in ensuring their proper functioning. If the guardrail is not strong enough, it will not be able to effectively stop vehicles in the event of a collision or other accidents, which may cause vehicles to cross the guardrail and run into the opposite lane or off the road, resulting in serious traffic accidents and casualties. Existing testing devices are complicated to operate, require simultaneous force application and fixation, and cannot perform tests on multiple forces, making them impractical. Utility Model Content

[0003] The purpose of this invention is to provide a strength testing device for traffic engineering guardrails to solve the problems mentioned in the background art.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: the use of the vehicle body and pulleys facilitates the movement of the testing equipment, ensuring a wide range of applicability. The use of the sliding rod, top plate, and spring allows for rapid displacement of the testing block based on spring force, delivering a powerful impact to the guardrail to be tested.

Detailed Implementation

[0013] 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 protection scope of the present utility model.

[0014] Please see Figure 1-3This utility model provides a traffic engineering guardrail strength testing device, including a vehicle body 1. Two pulleys 3 are rotatably connected to both sides of the vehicle body 1. A cavity is formed in the inner wall of the vehicle body 1. A cover plate 2 is connected to the surface of the vehicle body 1 by a hinge, covering the cavity. An elastic adjustment structure 6 is screwed to the inner wall of the vehicle body 1. A sliding rod 5 is inserted into the inner wall of the elastic adjustment structure 6. The sliding rod 5 passes through the vehicle body 1 and extends to the outside. A testing device is fixedly installed on the outer wall of the vehicle body 1 on the sliding rod 5. Block 4 and slide bar 5 are fixedly fitted with a top plate 13. A strong spring 9 is sleeved on the outer wall of slide bar 5. One end of the strong spring 9 is connected to the top plate 13, and the other end of the strong spring 9 is connected to the elastic adjustment structure 6. A rotating rod 10 is rotatably fitted through the inner wall of the vehicle body 1. A handle 7 is fixedly fitted on the outer wall of the outer end of the rotating rod 10. A nut 11 is fixedly fitted on the inner end of the rotating rod 10. A screw 12 is fixedly fitted on the side wall of the detection block 4. The screw 12 is screwed to the nut 11.

[0015] The use of the vehicle body 1 and pulley 3 facilitates the movement of the testing equipment, ensuring its wide applicability. The cover plate 2 facilitates the maintenance of internal components. Through the cooperation of the sliding rod 5, top plate 13, and strong spring 9, the force stored in the strong spring 9 controls the rapid displacement of the testing block 4, delivering a powerful impact to the guardrail to be tested. As needed, the elastic adjustment structure 6 can be adjusted to control the impact force of the testing block 4, thus adapting to the strength testing of guardrails of different specifications and models. It intuitively demonstrates the maximum force that the guardrail can withstand, making the testing convenient and highly practical. By turning the handle 7, the rotating rod 10 and nut 11 are controlled to rotate simultaneously. With the help of the screw 12, the initial position of the testing block 4 can be effectively fixed, and it can be effectively fixed when not in use.

[0016] The elastic adjustment structure 6 includes a screw cylinder 62, which is screwed to the inner wall of the vehicle body 1. A connecting plate 63 is fixedly mounted on the inner end of the screw cylinder 62, and the connecting plate 63 is connected to the strong spring 9. A rotating block 61 is fixedly mounted on the outer wall of the outer end of the screw cylinder 63.

[0017] The elastic force of the strong spring 9 needs to be adjusted. The rotating block 61 can be rotated to drive the screw cylinder 62 to move inside the vehicle body 1, and drive the connecting plate 63 to move. As the connecting plate 63 moves towards the inside of the vehicle body 1, it will squeeze the strong spring 9, reduce its extension path, and make it store more force.

[0018] It also includes a support structure 8, which is fixedly mounted on the side wall of the vehicle body 1. The support structure 8 includes a support 83, which is fixedly mounted on the side wall of the vehicle body 1. A hydraulic cylinder 81 is fixedly mounted on the inner wall of the support 83, and a support plate 82 is fixedly mounted on the lower end of the piston rod of the hydraulic cylinder 81.

[0019] When the support structure 8 is needed, the hydraulic cylinder 81 is activated, and it is fixed to the side wall of the vehicle body 1 through the support 83. The piston rod is controlled to drive the support plate 82 to move. When the support plate 82 contacts the ground, the reaction force will lift the vehicle body 1. At this time, the position of the vehicle body 1 can be effectively supported and fixed.

[0020] A push handle 14 is fixedly mounted on one side of the surface of the vehicle body 1.

[0021] The push handle 14 facilitates the movement of the vehicle body 1.
