Abstract
Description
Technical Field
[0001] This utility model relates to the field of guardrail detection technology, specifically a rapid detection device for road guardrails. Background Technology
[0002] Road safety barriers play a vital role in traffic safety, and ensuring their quality and performance meet standards is crucial. During the production process, rapid testing is conducted on the barriers. Fixing devices are used to secure the two ends of the barriers, and then pressure devices are used to locally compress the barriers to test their strength.
[0003] A Chinese patent with publication number CN216208166U discloses a strength testing device for highway traffic safety guardrails, including a fixing ring. A support block is fixedly connected to the bottom inner wall of the fixing ring, and a support groove is provided on the top of the support block. Positioning bolts pass through the front, back, and top sides of the fixing ring, and a single guardrail to be tested is fixed by rotating the positioning bolts.
[0004] The problem with the aforementioned technologies is that when inspecting multiple isolation fences, it is necessary to fix and remove the fences multiple times. The bolt fixing method makes the operation cumbersome and wastes time. Utility Model Content
[0005] The purpose of this invention is to provide a rapid inspection device for road guardrails. By using this device, the problem of repeatedly fixing and removing guardrails when inspecting multiple guardrails, and the cumbersome and time-consuming operation caused by bolt fixing, is solved.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid detection device for road guardrails, comprising an operating table, fixed components installed at both ends of the operating table, a test component disposed between the two fixed components, a buffer component disposed below the test component, the buffer component being mounted on the operating table, the fixed components comprising a fixed frame, a sliding groove one and a sliding groove two being provided on the fixed frame, the sliding groove two being located above the sliding groove one, a support block being slidably disposed within the sliding groove one, rack plates one being mounted on both sides of the support block, a gear being meshed on one side of the two rack plates one, a rotating shaft being mounted in the middle of the gear, the rotating shaft being rotatably mounted on the fixed frame, a moving block being disposed above the rotating shaft, the moving block being slidably disposed within the sliding groove two, a rack plate two being mounted below the moving block, the rack plate two being meshed with the gear, and a clamping block being mounted at one of the opposing ends of the two moving blocks.
[0007] The isolation barrier component is placed on the upper end of the support block. The output end of the test component presses down on the middle of the isolation barrier component, causing both ends of the isolation barrier component to exert force on the support block, thereby causing the support block to move downward. This causes rack plate one to move downward, rack plate one to drive the gear to rotate, the gear rotation to drive rack plate two to move, and rack plate two to drive the moving block to move, causing the two moving blocks to move towards each other, thereby causing the two clamping blocks to move towards each other and clamp the isolation barrier component. The operation is simple and does not require manual adjustment of the clamping parts.
[0008] Preferably, the opposing surfaces of the two clamping blocks are arranged in an arc shape, and both clamping blocks are made of rubber.
[0009] Preferably, the fixed frame is provided with a spring groove, which is located below the sliding groove. The lower end of the support block slides through two limiting posts, which are installed on the fixed frame. A spring is sleeved on the outside of the limiting posts, which is located in the spring groove. The upper end of the spring is fixedly connected to the support block, and the lower end of the spring is fixedly connected to the fixed frame.
[0010] After the test is completed, the barrier component is no longer under downward pressure. The spring exerts upward force on the support block, causing the support block to move upward. This causes the two clamping blocks to move away from each other, thus releasing the barrier component from its fixation. It can be removed at any time and replaced with another set of barrier components that need to be tested.
[0011] Preferably, the test assembly includes a support frame, a hydraulic rod is mounted on the upper end of the support frame, a pressure sensor is mounted on the output end of the hydraulic rod, and a pressing block is mounted on the lower end of the pressure sensor.
[0012] The hydraulic rod is activated, and its output end drives the pressure sensor and pressing block to move downwards. The pressing block squeezes the barrier component, and the pressure sensor records the maximum pressure that the barrier component can withstand, thereby quickly detecting the quality and performance of the barrier component.
[0013] Preferably, the buffer assembly includes a buffer frame located below the pressing block, a sliding block slidably mounted inside the buffer frame, and a buffer block mounted on the upper end of the sliding block.
[0014] The buffer block prevents the isolation barrier component from being unable to withstand the pressure of the pressing block, breaking off and moving rapidly downwards, causing damage to the testing device.
[0015] Preferably, a plurality of springs are installed at the lower end of the sliding block, and the lower ends of the springs are fixedly connected to the buffer frame.
[0016] Spring 2 acts as a buffer for the sliding block.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] This utility model proposes a rapid testing device for road guardrails. The fixing component includes a fixing frame with a support block and two clamping blocks. The guardrail component is placed on the upper end of the support block. The testing component presses the middle of the guardrail component, and the two ends of the guardrail component exert force on the support block, causing the two clamping blocks to move towards each other and clamp the guardrail component. The operation is simple and does not require manual adjustment of the clamping parts. After the test is completed, the guardrail component is no longer under downward pressure. The spring at the lower end of the support block exerts upward force on the support block, causing the two clamping blocks to move away from each other, thereby releasing the fixation of the guardrail component. It can be removed at any time and replaced with another set of guardrail components that need to be tested. Attached Figure Description

[0026] 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.
[0027] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.
[0028] Combination Figures 1-4 A rapid detection device for road guardrails includes an operating platform 1, with fixing components 2 installed at both ends of the operating platform 1. A test component 3 is arranged between the two fixing components 2, and a buffer component 4 is arranged on the lower side of the test component 3. The buffer component 4 is installed on the operating platform 1. The fixing components 2 include a fixing frame 21, with a sliding groove 1 211 and a sliding groove 212 formed on the fixing frame 21. The sliding groove 212 is located above the sliding groove 1 211. A support block 22 is slidably arranged in the sliding groove 1 211. A rack plate 1 221 is installed on both sides of the support block 22. A gear 23 is meshed on one side of the two rack plates 1 221. A rotating shaft 24 is installed in the middle of the gear 23. The rotating shaft 24 is rotatably mounted on the fixing frame 21. A moving block 25 is arranged on the upper side of the rotating shaft 24 and is slidably arranged in the sliding groove 212. A buffer component 4 is installed on the lower side of the moving block 25. The device includes a rack plate 251, which meshes with a gear 23. Two moving blocks 25 are fitted with clamping blocks 26 at their opposite ends. The surfaces of the opposite ends of the clamping blocks 26 are arc-shaped. Both clamping blocks 26 are made of rubber. The barrier component is placed on top of the support block 22. The output end of the test component 3 presses downwards onto the middle of the barrier component, causing both ends of the barrier component to exert force on the support block 22. This causes the support block 22 to move downwards, which in turn causes the rack plate 221 to move downwards. The rack plate 221 drives the gear 23 to rotate, which in turn moves the rack plate 251. The movement of the rack plate 251 moves the moving blocks 25, causing the two moving blocks 25 to move towards each other. This, in turn, causes the two clamping blocks 26 to move towards each other, clamping the barrier component. The operation is simple and requires no manual adjustment of the clamping components.
[0029] Combination Figures 2-4 A spring groove 213 is provided on the fixed frame 21. The spring groove 213 is located below the sliding groove 211. The lower end of the support block 22 slides through two limiting posts 222. The limiting posts 222 are installed on the fixed frame 21. A spring 223 is sleeved on the outside of the limiting posts 222. The spring 223 is located in the spring groove 213. The upper end of the spring 223 is fixedly connected to the support block 22, and the lower end of the spring 223 is fixedly connected to the fixed frame 21. After the test is completed, the isolation fence component is no longer subjected to downward pressure. The spring 223 exerts upward force on the support block 22, thereby causing the support block 22 to move upward, thereby causing the two clamping blocks 26 to move away from each other, thereby releasing the fixation of the isolation fence component. It can be removed at any time and replaced with another set of isolation fence components that need to be tested.
[0030] Combination Figure 1 , Figure 5The test component 3 includes a support frame 31, with a hydraulic rod 32 mounted on the upper end of the support frame 31. A pressure sensor 33 is mounted on the output end of the hydraulic rod 32, and a pressing block 34 is mounted on the lower end of the pressure sensor 33. When the hydraulic rod 32 is activated, the output end of the hydraulic rod 32 drives the pressure sensor 33 and the pressing block 34 to move downward. The pressing block 34 squeezes the barrier component, and the pressure sensor 33 records the maximum pressure that the barrier component can withstand, thereby quickly detecting the quality and performance of the barrier component.
[0031] Combination Figure 1 , Figure 6 The buffer assembly 4 includes a buffer frame 41, which is located below the pressing block 34. A sliding block 42 is slidably installed inside the buffer frame 41. A buffer block 43 is installed on the upper end of the sliding block 42. A plurality of springs 44 are installed on the lower end of the sliding block 42. The lower end of the springs 44 is fixedly connected to the buffer frame 41. The buffer block 43 can prevent the isolation barrier component from being unable to withstand the pressure of the pressing block 34 and breaking, and then moving downward rapidly to damage the testing device. The springs 44 play a buffering role on the sliding block 42.
[0032] Working principle: The isolation barrier component is placed on the upper end of the support block 22. The output end of the test component 3 presses down on the middle of the isolation barrier component, causing both ends of the isolation barrier component to exert force on the support block 22, thereby causing the support block 22 to move downward. This causes the rack plate 1 221 to move downward, which in turn drives the gear 23 to rotate. The rotation of the gear 23 drives the rack plate 251 to move, which in turn drives the moving block 25 to move. This causes the two moving blocks 25 to move towards each other, thereby causing the two clamping blocks 26 to move towards each other and clamp the isolation barrier component. The operation is simple and does not require manual adjustment of the clamping parts. After the test is completed, the isolation barrier component is no longer under downward pressure. The spring 1 223 exerts upward force on the support block 22, causing the support block 22 to move upward. This causes the two clamping blocks 26 to move away from each other, thereby releasing the fixation of the isolation barrier component. It can be removed at any time and replaced with another set of isolation barrier components that need to be tested.
