Description

Technical Field

[0001] The present application relates to the technical field of strength detection devices, and in particular to a concrete strength detection device. Background Art

[0002] Concrete, abbreviated as "tóng", is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement concrete obtained by mixing cement as the cementitious material, sand and stone as aggregates and water (which may contain admixtures and additives) in a certain proportion.

[0003] The existing concrete strength detection device, as described in the patent with announcement number CN218212396U, includes a hydraulic cylinder, a top platform, a hydraulic rod, a detection platform and a base, wherein the top platform is arranged directly above the base, and pillars are arranged at the four corner ends between the detection platform and the base, and threaded sleeves are arranged between the pillars on both sides, and clamping parts are arranged inside the threaded sleeves, and the clamping parts include a rotary disk, a threaded rod, a support rod and a clamping plate. When the concrete strength detection device provided by the utility model is used, the concrete block to be detected is placed on the detection platform, and then the hydraulic cylinder is started to push the hydraulic rod downward, and then the top of the concrete block is pushed to perform a compressive stress test, during which the rotary disks on both sides are rotated so that the clamping plate at the front end is pushed against the side of the concrete block, so that the test is more stable and the test data is more accurate.

[0004] In view of the above-mentioned related technologies, the inventor believes that there is no protective device during concrete testing. When the concrete is struck and tested, flying stones when the concrete is broken can easily cause danger to people, and the broken concrete can easily pollute the surrounding environment. It takes a long time to clean up the debris, wasting manpower and material resources. Utility Model Content

[0005] In order to improve the problem that there is no protective device during concrete testing, when the concrete is struck and tested, flying stones may easily cause danger to people when the concrete is broken, and the broken concrete may easily pollute the surrounding environment, and it takes a long time to clean up the broken debris, wasting manpower and material resources, the present application provides a concrete strength testing device.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A concrete strength testing device comprises a fixed frame, an electric telescopic rod is fixedly provided at the bottom of the inner cavity of the fixed frame, a fixed plate is fixedly provided at the bottom of the electric telescopic rod, a hydraulic cylinder is fixedly provided at the top of the fixed plate, a hydraulic piston rod is slidably connected to the inner cavity of the hydraulic cylinder, a detection probe is fixedly provided at the bottom of the hydraulic piston rod, a connecting rod is fixedly provided at the bottom of the fixed plate, a protective plate is fixedly provided at the bottom of the connecting rod, a testing platform is fixedly provided at the bottom of the inner cavity of the fixed frame, a sliding groove is provided on the inner wall of the testing platform, a baffle is slidably connected to the inner cavity of the sliding groove, a collecting box is slidably connected to the inner cavity of the testing platform, threaded rods are threadedly connected to both sides of the fixed frame, a rotating handle is fixedly provided at one end of the threaded rod, and a clamping plate is fixedly provided at the other end of the threaded rod.

[0008] By adopting the above technical solution, concrete is placed on the baffle, and the clamping plate is fitted with the concrete by turning the handle to rotate the threaded rod to fix the concrete. When testing, the fixing plate is driven downward by the electric telescopic rod to make the protective plate fit on the top of the testing platform, and the hydraulic cylinder is started to drive the detection probe to crush the concrete through the hydraulic piston rod. The protective plate covers the testing platform so that the detection probe does not splash gravel when crushing the concrete. The broken concrete after pulling the baffle will enter the collection box, and the concrete is collected through the collection box.

[0009] Optionally, the fixing plate is slidably connected to the inner wall of the fixing frame via an electric telescopic rod.

[0010] By adopting the above technical solution, the position of the protective plate is adjusted by moving the fixed plate so that the protective plate can cover the top of the testing platform.

[0011] Optionally, a through hole is provided on the top of the protective plate and directly below the detection probe.

[0012] By adopting the above technical solution, the hydraulic piston rod can be normally extended and retracted through the through hole, and will not interfere with the detection of the detection probe.

[0013] Optionally, fixing holes are provided on both sides of the detection platform.

[0014] By adopting the above technical solution, the clamping plate can pass through the fixing hole to fix the concrete placed on the baffle.

[0015] Optionally, a pulling handle is fixedly provided on the baffle and the front side of the collection box.

[0016] By adopting the above technical solution, after the concrete is broken by pulling the handle, it is convenient to pull the baffle so that the concrete on the fixed frame can enter the collection box, and at the same time, it is convenient to pull the collection box to clean the concrete in the collection box.

[0017] Optionally, a rubber pad is fixedly provided on one side of the clamping plate.

[0018] By adopting the above technical solution, the connection between the clamping plate and the concrete can be made more stable by arranging the rubber pad, and damage caused by friction of the clamping plate can be avoided.

[0019] In summary, the beneficial effects of this application are as follows:

[0020] The present application uses the coordination of structures such as connecting rods, protective plates, and collection boxes. When concrete is placed on a test bench for testing, the fixed plate is driven downward by an electric telescopic rod to make the protective plate fit against the top of the test bench. The protective plate covers the test bench so that when the test probe breaks the concrete, no gravel will splash, thereby ensuring the safety of the test personnel. The broken concrete will enter the collection box after the baffle is pulled, and the concrete will be collected through the collection box to prevent the concrete from causing environmental pollution.
