Description

Technical Field

[0001] This utility model relates to the field of building material testing technology, and in particular to a building material impact resistance testing device. Background Technology

[0002] Building materials are a general term for all materials used in constructing and building structures. They can be categorized into many types based on their properties, uses, and sources. Building materials are diverse, but can be broadly classified into: metallic materials (including ferrous and non-ferrous metals), non-metallic materials (such as clay products and cement), organic materials (including plant-based materials, plastics, coatings, and adhesives), and asphalt materials. Composite materials include asphalt concrete, polymer concrete, etc., which are generally composed of organic materials.

[0003] Currently, the most common methods for testing the impact resistance of building materials are manual hammering or suspending a heavy object at a suitable height using a traction rope and then dropping the object to test its impact resistance.

[0004] However, in actual testing, workers usually use the same weight of impactor to conduct impact tests on building materials at different heights. Since different building materials exhibit different impact resistance when faced with impactors of different weights, traditional testing methods make it inconvenient for workers to switch between impactors of different weights according to the testing requirements of building materials, thus affecting the testing efficiency of building materials. Furthermore, existing testing devices are not convenient for adjusting the impact position of building materials, thus failing to meet the needs of impact testing at different points on building materials.

[0031] Example:

[0032] Reference Figures 1-6 This utility model provides a building material impact resistance testing device, including a housing 1 with a bracket 2 mounted on the top, and a shell 4 connected to the bracket 2 via a lifting component; multiple impact objects 3 of different weights, arranged in a ring on the shell 4, wherein the shell 4 is provided with a driving part for driving the multiple impact objects 3 to move in a ring, the number of impact objects 3 being 4 to 8, preferably 6 in this embodiment; a support block 6 for supporting the building material, connected to the housing 1 via a guide component, the support block 6 having anti-slip texture 9 located on the top of the support block 6 for stabilizing the building material; wherein the housing 1 is provided with an adjustment part for driving the support block 6 to move laterally; a ruler 8 is fixedly mounted on the bracket 2, the surface of the ruler 8 having scale lines for easy reference and viewing of the height of the impact objects 3; a stop frame 10 is fixedly connected to the top of the housing 1, the support block 6 being located within the stop frame 10 for stopping the impact objects 3 falling onto the building material and preventing the impact objects 3 from falling off the housing 1.

[0033] Specifically, during use, the drive unit allows multiple impactors 3 to rotate in turn, facilitating the switching of positions between impactors 3 of different weights. This enables workers to quickly select an impactor 3 of appropriate weight to conduct impact resistance testing on building materials, greatly simplifying the testing process and improving testing efficiency. The adjustment unit allows the support block 6 and building materials to move laterally, facilitating the adjustment of the impact position and enabling impact resistance testing at different points on the building materials. This meets the needs of impact testing at different points on building materials. The lifting mechanism allows for adjustment of the height of the impactors 3, making it convenient to test the impact resistance of building materials when subjected to impactors 3 from different heights.

[0034] The lifting component includes a cylinder 41 fixedly mounted on a bracket 2, with a connecting plate 42 fixedly connected to the output end of the cylinder 41, and a housing 4 fixedly connected to the connecting plate 42.

[0035] Specifically, during use, by activating cylinder 41, the output end of cylinder 41 drives connecting plate 42 and housing 4 to move upward or downward, which facilitates the adjustment of the height of the impactor 3, thereby making it convenient to test the impact resistance performance of building materials when subjected to impactors 3 falling from different heights.

[0036] The drive unit includes a first motor 5 fixedly installed inside the housing 4. A rotating rod 51 is rotatably connected to the housing 4. A worm gear 52 is fixedly connected to the rotating rod 51. The output end of the first motor 5 is fixedly connected to a worm 53 that meshes with the worm gear 52. The impactor 3 is connected to the rotating rod 51 by a fastener.

[0037] Specifically, in use, the first motor 5 is started, driving the worm 53, worm wheel 52 and rotating rod 51 to rotate, which in turn drives the fixing parts and multiple impactors 3 to rotate in turn, so that the impactors 3 with appropriate weights are directed toward the building materials. This allows for easy switching of the positions of multiple impactors 3 with different weights, so that workers can quickly select the impactors 3 with appropriate weights to conduct impact resistance testing on the building materials, which greatly facilitates the workers' testing work and helps to improve the testing efficiency of building materials.

[0038] The fixing component includes a connecting plate 31 fixedly installed on the rotating rod 51. The bottom of the connecting plate 31 has multiple positioning grooves 32 arranged in a ring. Each of the multiple positioning grooves 32 has an electromagnet 33 fixedly installed in it. The number of positioning grooves 32 is the same as the number of impact objects 3. The impact objects 3 are magnetically connected to the electromagnets 33. In this solution, the electromagnets 33 can be powered by a storage battery.

[0039] Specifically, by turning on the electromagnet 33, the impactor 3 can be magnetically fixed in the positioning groove 32. By turning off the electromagnet 33, the fixation of the impactor 3 can be released, allowing the impactor 3 to fall onto the building material on top of the support block 6.

[0040] A guide tube 43 is fixedly connected to the bracket 2, and a guide rod 44 is fixedly connected to the housing 4. The guide rod 44 is longitudinally slidably connected inside the guide tube 43.

[0041] Specifically, the stability of the housing 4 and the impactor 3 during lifting and lowering can be improved by setting up the guide tube 43 and the guide rod 44.

[0042] The guide includes a T-shaped block 61 fixedly connected to the bottom of the support block 6, and a T-shaped groove 62 is provided on the top of the chassis 1. The T-shaped block 61 is laterally slidably connected in the T-shaped groove 62.

[0043] Specifically, the T-shaped block 61 and T-shaped groove 62 can guide the support block 6 and also provide limiting support for the support block 6, thereby improving the load-bearing capacity of the support block 6.

[0044] The adjustment unit includes a second motor 7 fixedly installed inside the housing 1. A screw 71 is rotatably connected inside the housing 1. The output end of the second motor 7 and the surface of the screw 71 are both fixedly connected to meshing gears 72. A slider 73 is laterally slidably connected to the housing 1. The slider 73 is threadedly connected to the screw 71. A support block 6 is fixedly connected to the slider 73.

[0045] Specifically, during use, the second motor 7 is started in either the forward or reverse direction. The output end of the second motor 7 drives the gear 72 and the screw 71 to rotate. Under the action of the screw, the slider 73 drives the support block 6 and the building material to move laterally. This allows for easy adjustment of the impact position of the building material, thereby facilitating impact resistance testing at different points on the building material and meeting the needs of impact testing at different points on the building material.

[0046] During use, the building material impact resistance testing device first places the building material on top of the support block 6, and then starts the cylinder 41. The output end of the cylinder 41 drives the connecting plate 42 and the housing 4 to move upward or downward, which makes it easy to adjust the height of the impactor 3, thereby facilitating the testing of the building material's impact resistance performance when subjected to impactors 3 from different heights.

[0047] Furthermore, by starting the first motor 5, the worm gear 53, worm wheel 52, and rotating rod 51 are driven to rotate, which in turn drives the connecting plate 31 and multiple impactors 3 to rotate in turn. This allows the impactors 3 of appropriate weight to be vertically oriented toward the building materials, facilitating the switching of positions between multiple impactors 3 of different weights. This enables workers to quickly select the impactor 3 of appropriate weight to conduct impact resistance testing on the building materials, greatly facilitating the workers' testing work and thus helping to improve the efficiency of building material testing.

[0048] Meanwhile, once the impactor 3 is selected, the electromagnet 33 corresponding to the selected impactor 3 can be turned off to release the fixation of the impactor 3, so that the selected impactor 3 falls onto the building material to test the impact resistance of the building material.

[0049] In addition, during the testing process, the second motor 7 is started in either the forward or reverse direction. The output end of the second motor 7 drives the gear 72 and the screw 71 to rotate. Under the action of the screw, the slider 73 drives the support block 6 and the building material to move laterally. This makes it easy to adjust the impact position of the building material, thereby facilitating the impact resistance testing of different points on the building material and meeting the needs of impact testing at different points on the building material.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
