Description

Technical Field

[0001] This utility model relates to the field of highway engineering testing technology, and in particular to a testing and inspection device for highway engineering. Background Technology

[0002] In the field of highway engineering, crack sealant is a core material for repairing pavement cracks, and its performance directly affects the service life of the road and driving safety. However, traditional crack sealant testing methods have revealed many limitations in practical applications, specifically as follows:

[0003] 1. For high-strength highway engineering projects, it is necessary to systematically test the bonding strength of various joint sealants after curing in order to select the optimal material. However, most existing testing devices are single-station designs, which can only test one type of joint sealant at a time. This results in a lengthy testing process, making it impossible to quickly complete multiple sets of comparative experiments, which seriously affects the efficiency of material selection and thus delays the project schedule.

[0004] 2. Traditional testing devices use an integrated structure, requiring manual cleaning of any residual sealant inside the device after testing. Because the sealant is highly adhesive after curing, the cleaning process is time-consuming and labor-intensive, and easily leaves behind sealant fragments, contaminating subsequent test results, reducing data accuracy, and creating a vicious cycle of "testing-cleaning-error accumulation." Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a testing and inspection device for highway engineering. The test box can be quickly inserted and removed without the need for complex fixing devices, effectively reducing the time for injecting and cleaning the sealant. It also improves the ease of operation when changing test boxes or cleaning residual sealant. Furthermore, it can simultaneously perform tests on multiple sets of sealant, thus improving testing efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A testing and inspection device for highway engineering includes a base plate, on the upper end of which a first vertical plate and a second vertical plate are fixedly installed. The first vertical plate and the second vertical plate are symmetrically arranged. Fixing rods are fixedly installed at equal intervals on the side wall of the first vertical plate. A fixing plate is fixedly installed at the other end of the fixing rod.

[0008] The second vertical plate has multiple sliding plates at equal intervals at one end, corresponding to the fixed plate. Each sliding plate has a material placement mechanism for injecting grout on the side opposite to the fixed plate.

[0009] The second vertical plate is provided with a pulling mechanism for pulling the sliding plate.

[0010] Preferably, the material placing mechanism includes a test box arranged inside the fixed plate. Limit plates are fixedly installed on both the front and rear sides of the test box, and a handle is fixedly installed at the upper end of the test box.

[0011] Preferably, "middle"-shaped grooves are formed on the side walls of both the fixed plate and the sliding plate.

[0012] Preferably, the test box is formed by welding a right-angled U-shaped plate and a bottom rectangular plate.

[0013] Preferably, the pulling mechanism includes a hydraulic cylinder fixedly installed on the side wall of the second vertical plate. A connecting plate is fixedly installed at the telescopic end of the hydraulic cylinder, and a tension sensor is arranged between the connecting plate and the sliding plate.

[0014] Preferably, a guide rod is fixedly installed on the side wall of the connecting plate, and the other end of the guide rod penetrates through the second vertical plate and is slidably connected to it.

[0015] The utility model has the following beneficial effects:

[0016] The "middle"-shaped groove structures of the fixed plate and the sliding plate enable the test box to be quickly inserted and removed without a complex fixing device, reducing the time for injecting and cleaning the caulking gum. The limit plates on both sides of the test box cooperate with the "middle"-shaped grooves to ensure the stable position of the test box during the tensile test and avoid data errors caused by deviation. The handle on the top of the test box facilitates manual operation, especially when replacing the test box or cleaning the residual caulking gum, improving the operation convenience;

[0017] The stable pulling force is provided by the hydraulic cylinder, avoiding the unevenness of manual operation and ensuring the consistency of the pulling force application process in each test. The guide rod penetrates through the second vertical plate and is fixed to the connecting plate, providing lateral support when the sliding plate moves and preventing the reading fluctuation of the tension sensor caused by eccentric loading;

[0018] The tension sensor is directly connected to the sliding plate and the connecting plate, and the tensile strength of the caulking gum during the movement of the sliding plate is recorded in real time, avoiding the error caused by indirect measurement. In addition, multiple groups of caulking gum can be tested simultaneously, improving the test efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Refer to Figures 1-3 , a test detection device for highway engineering, including a bottom plate 1. A first vertical plate 2 and a second vertical plate 10 are fixedly installed at the upper end of the bottom plate 1. The first vertical plate 2 and the second vertical plate 10 are symmetrically arranged. Fixed rods 3 are fixedly installed at equal intervals on the side wall of the first vertical plate 2, and the other ends of the fixed rods 3 are fixedly installed with fixed plates 4;

[0027] A plurality of sliding plates 6 corresponding to the fixed plates 4 are arranged at equal intervals at one end of the second vertical plate 10. "Chinese character middle" shaped grooves are opened on the side walls of the fixed plates 4 and the sliding plates 6. A material placing mechanism for injecting sealant is arranged on the side of the sliding plate 6 opposite to the fixed plate 4. The material placing mechanism includes a test box 5 arranged inside the fixed plate 4. The test box 5 is formed by welding a right-angled U-shaped plate and a bottom rectangular plate. Limiting plates 12 are fixedly installed on both the front and rear sides of the test box 5, and a handle 11 is fixedly installed at the upper end of the test box 5;

[0028] The second vertical plate 10 is provided with a pulling mechanism for pulling the sliding plate 6. The pulling mechanism includes a hydraulic cylinder 9 fixedly installed on the side wall of the second vertical plate 10. A connecting plate 7 is fixedly installed on the telescopic end of the hydraulic cylinder 9. A tension sensor is provided between the connecting plate 7 and the sliding plate 6. A guide rod 8 is fixedly installed on the side wall of the connecting plate 7. The other end of the guide rod 8 passes through the second vertical plate 10 and is slidably connected to it.

[0029] Working principle:

[0030] Start the hydraulic cylinder 9. The extension end of the hydraulic cylinder 9 pushes the connecting plate 7 to move. The connecting plate 7 is connected to the sliding plate 6 through the tension sensor, thereby driving the sliding plate 6 to move and align the sliding plate 6 with the fixed plate 4, realizing the docking of the two test boxes 5. At the same time, the guide rod 8 slides in the second vertical plate 10 to ensure the stability of the movement of the connecting plate 7.

[0031] The sealant is injected into the test box 5 to complete the material placement operation. Then, the sliding plate 6 is moved by the hydraulic cylinder 9 and the connecting plate 7. During the movement of the sliding plate 6, the tension sensor detects the tension on the sliding plate 6 in real time. The bonding performance between the sealant and the fixed plate 4 and the sliding plate 6 can be analyzed through the tension data, thereby completing the test of the sealant used in highway engineering.

[0032] Due to the design of multiple test boxes 5, multiple sets of potting compounds can be tested simultaneously, which improves the efficiency of testing.

[0033] After the test is completed, the test box 5 can be lifted by pulling the handle 11 to remove the test box 5 for cleaning of the potting compound.
