Description

Technical Field

[0001] This utility model belongs to the field of concrete testing, and in particular relates to a concrete strength tester for highway bridge construction. Background Technology

[0002] Highway bridge engineering includes the main bridge structure and ancillary engineering facilities at the bridge site. A concrete strength tester is a specialized instrument used to test and evaluate the strength of concrete. It can be used to directly test the strength of concrete structures on-site, such as construction sites, to promptly understand the quality status of the concrete. This helps construction companies and quality supervision departments to effectively monitor and control the strength of concrete during construction, ensuring that the project quality meets requirements.

[0003] For example, Chinese Patent Publication No. CN221377435U, entitled "A Concrete Strength Tester for Highway Bridge Construction," discloses the tester body, which is equipped with protective components and a dust-absorbing structure. This protects workers during concrete crushing tests and allows for rapid cleaning of concrete debris. Before cleaning the debris, the crushed concrete fragments also need to be cleaned. Similarly, Chinese Patent Publication No. CN219245178U, also entitled "Concrete Strength Tester," discloses a vacuum cleaner and an electric actuator. The electric actuator lifts a carrier plate, facilitating the cleaning of the crushed concrete.

[0004] However, while it facilitates the cleaning of the broken concrete, the large number of fragments still requires considerable time for staff to process, thus extending the preparation time for the next concrete strength test. Summary of the Invention

[0005] In order to overcome the shortcomings of existing technologies, this utility model provides a concrete strength tester for highway bridge construction, which can facilitate the processing of broken concrete blocks.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A concrete strength tester for highway bridge construction includes a testing frame, a worktable, a baffle, a slide bar, a push plate, and a drive assembly. The testing frame has a feed inlet and a discharge outlet. The worktable is slidably mounted on the testing frame. The baffle is fixedly mounted on the edge of the worktable and fixedly connected to the testing frame. The slide bar is located in the direction of the feed inlet of the testing frame. The push plate is slidably mounted on the slide bar. The worktable is connected to the drive assembly for driving the worktable to slide horizontally. When the worktable moves towards the feed inlet, the push plate can abut against the upper surface of the worktable. A discharge guide plate is inclinedly provided at the bottom of the worktable.

[0008] Furthermore, the testing frame is also fixed with a slide rail, the worktable is slidably disposed on the slide rail, the bottom of the push plate can abut against the slide rail, the push plate also has a guide groove, and the groove wall of the guide groove is located on the moving path of the worktable.

[0009] Preferably, the top of the slide bar is also fixed with a first limiting hook for restricting the movement of the push plate.

[0010] Furthermore, the drive assembly includes a drive rod and a drive motor for driving the drive rod to rotate, the drive rod engaging with the lower surface of the worktable. This configuration forms a rack and pinion linear motion mechanism.

[0011] Preferably, the slide bar is also slidably provided with a protective plate, the protective plate having mesh.

[0012] Preferably, the protective plate includes a protective rod slidably disposed on the slide rod and a mesh plate rotatably disposed on the protective rod.

[0013] Furthermore, a second limiting hook is fixed to the bottom of the slide bar to restrict the movement of the protective plate.

[0014] Preferably, the bottom of the protective plate has an extension rod that can abut against the second limiting hook.

[0015] A material discharge box is also provided at the material discharge port, and the material discharge box is located below the material discharge guide plate.

[0016] The baffle has three sections. When testing concrete, the baffle can block the concrete block in three directions, with the fourth direction being the feed inlet of the testing frame.

[0017] The main advantages of this invention are as follows: after crushing, simply move the baffle to contact the worktable, and then drive the worktable to move. The baffle will automatically push the crushed concrete into the discharge port, which shortens the time for workers to handle the crushed concrete blocks and thus improves the efficiency of concrete strength testing.

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] Reference Figure 1 and Figure 2 A concrete strength tester for highway bridge construction includes a test frame 1, a workbench 2, and multiple baffles 13. The workbench 2 is slidably mounted on the test frame 1. There are three baffles 13, which are located at the edge of the workbench 2 and fixedly connected to the test frame 1. A concrete block is placed on the workbench 2. When testing the concrete, the baffles 13 can block the concrete block in three directions. The fourth direction is the direction of the feed inlet 11 of the test frame 1. The test frame 1 also has a discharge port 12.

[0023] The drive assembly enables the worktable 2 to slide horizontally towards the feed inlet 11. The drive assembly includes a drive rod 21 and a drive motor (not shown in the figure). The drive motor allows the drive rod 21 to rotate, and the drive rod 21 engages with the lower surface of the worktable 2. When the worktable 2 needs to move, rotating the drive rod 21 moves the worktable 2. The inspection frame 1 is also fixed with a slide rail 15, one end of which extends towards the discharge port. The worktable 2 is slidably connected to the slide rail 15, and as the drive rod 21 rotates, the worktable 2 can slide relative to the slide rail 15.

[0024] The feed inlet 11 of the testing frame 1 is also provided with a slide bar 3. In this application, there are two slide bars 3. The slide bar 3 is slidably connected to a push plate 31. The upper end of the slide bar 3 is fixed with a first limiting hook 33. When the push plate 31 moves upward, the first limiting hook 33 can lock the push plate 31, thereby restricting the movement of the first limiting hook 33. When the push plate 31 moves downward, the bottom of the push plate 31 can abut against the slide rail 15. The push plate 31 also has a guide groove 32. The groove wall of the guide groove 32 is inclined and is located on the moving path of the worktable 2. After the concrete block is broken, the worktable 2 is driven to move. One end of the worktable 2 can push the groove wall of the guide groove 32, thereby allowing the push plate 31 to move upward. At this time, the bottom of the push plate 31 abuts against the upper surface of the worktable 2. As the worktable 2 moves, the push plate 31 can push the broken concrete on the worktable 2.

[0025] The bottom of the workbench 2 is inclined and equipped with a material guide plate 14. A material box 16 is also provided at the material discharge port 12, which is located below the material guide plate 14. The push plate 31 pushes the concrete fragments into the material guide plate 14, and then the material guide plate 14 can guide the fragments to the material box 16, where the material box 16 collects the concrete fragments.

[0026] The slide bar 3 is also slidably equipped with a protective plate 34, which covers the protective bar 36 and the mesh plate 37. The protective plate 34 is slidably mounted on the slide bar 3, and the upper end of the mesh plate 37 is rotatably mounted on the protective bar 36. The mesh plate 37 has mesh holes 35. A second limiting hook 38 is fixed to the bottom of the slide bar 3 to restrict the movement of the protective plate 34. The bottom of the protective plate 34 has an extension rod 39. When crushing concrete, the extension rod 39 can abut against the second limiting hook 38, keeping the protective plate 34 at the feed inlet 11, which is convenient for observation and prevents large pieces of concrete from coming out of the discharge outlet during crushing.

[0027] The working process of this embodiment is as follows: When testing the strength of concrete, it is necessary to crush the concrete. At this time, the protective plate 34 is moved so that the extension rod 39 of the protective plate 34 abuts against the second limit hook 38, and the entire protective plate 34 is located at the feed inlet 11 of the testing frame 1. When the crushing is finished and cleaning is required, the protective plate 34 is reset first, and then the push plate 31 is moved so that the bottom of the push plate 31 abuts against the slide rail 15. Then the worktable 2 is moved. As the worktable 2 moves, the worktable 2 will push the push plate 31 so that the bottom of the push plate 31 abuts against the upper surface of the worktable 2. Then the worktable 2 continues to move, and the push plate 31 will push the crushed concrete on the worktable 2, so that the crushed concrete falls into the material drop box 16.

[0028] The embodiments described in this specification are merely examples of implementations of the inventive concept and are for illustrative purposes only. The scope of protection of this utility model should not be considered limited to the specific forms described in these embodiments; rather, it extends to equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
