Description

Technical Field

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

[0002] In order to control the quality of building structures and ensure that the strength of structural concrete can meet the design requirements, it is important to conduct strength testing on concrete, which generally includes the ability of concrete to resist compression, tension, bending, shear and other stresses.

[0003] A Chinese patent discloses a concrete strength testing device, with the authorization announcement number CN218212396U. The patent includes a hydraulic cylinder, a top platform, a hydraulic rod, a testing platform and a base. The top platform is arranged directly above the base, and pillars are arranged at the four corner ends between the testing platform and the base. A threaded sleeve is arranged between the pillars on both sides, and a clamping member is arranged inside the threaded sleeve. The clamping member includes a rotary disc, a threaded rod, a support rod and a clamping plate. The above utility model places the concrete block to be tested on the testing platform, then starts the hydraulic cylinder to push the hydraulic rod downward, and then pushes it against the top of the concrete block for compressive stress testing. During this period, the rotary discs on both sides are rotated so that the clamping plate at the front end pushes against the side of the concrete block. The test is more stable and the test data is more accurate. However, the above detection device does not protect the concrete block when performing pressure testing. The concrete block is easily crushed by pressure and splashes, which is not conducive to ensuring the safety of surrounding operators. At the same time, when clamping and fixing the concrete block, it is necessary to rotate the dials on both sides so that the clamping plate can be pressed against the side of the concrete block. Multiple tests require frequent rotation of the dial for clamping and fixing, which is cumbersome and not conducive to improving detection efficiency. Therefore, those skilled in the art provide a concrete strength detection device to solve the problems raised in the above background technology. Utility Model Content

[0010] By adopting the above technical solution, the second electric push rod drives the pressure plate to move downward and fit the concrete block to be tested, so that compressive stress detection can be carried out. Under the action of the pressure sensor, the detection process can be better monitored.

[0011] Preferably, one end of the movable plate is rotatably connected to the base, and a handle is fixedly connected to a side of the movable plate away from the rotatable connection.

It is easy to use and is conducive to improving the detection efficiency of concrete.

[0013] Preferably, a transparent plate is embedded on the outer side of the protective cover.

[0014] By adopting the above technical solution, the transparent plate can facilitate the inspection personnel to observe the inspection status of the internal concrete blocks.

[0015] Preferably, the movable plate is connected to the base via a hinge.

[0016] By adopting the above technical solution, the movable plate connected by the hinge can rotate more flexibly, thereby making it more convenient to flip the movable plate.

[0017] Preferably, the two first electric push rods, the second electric push rod and the pressure sensor are all electrically connected to an external control device.
