Technical Field

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

[0002] In actual testing, to fully evaluate the compressive properties of concrete, it is necessary to conduct compressive tests under different load areas. This helps us understand the compressive behavior of concrete under different conditions and thus more accurately evaluate its performance.

[0003] An existing patent (publication number: CN219265933U) discloses a concrete pressure testing device comprising a circular plate. The device features a support rod fixed to the center of the circular plate, with one end of a connecting rod hingedly connected to the center of each lower portion of the support rod. The other end of each pair of connecting rods is hingedly connected to the underside of the horizontal bar of an L-shaped rod. The upper end of the vertical bar of each L-shaped rod is fixedly connected to the housing of an electric push rod, and the telescopic rod of each electric push rod is fixed to a pressure detector. This utility model relates to the technical field of pressure testing equipment, specifically to a concrete pressure testing device that facilitates concrete pressure testing.

The pressure detector moves in the direction of the concrete and applies pressure to it to realize the strength detection of the concrete. However, it cannot change the contact area between the detection device and the concrete, and thus cannot measure the compressive strength of the concrete under the same pressure and different force-bearing areas.

[0017] Furthermore, the outer surface of each replacement plate is fixedly connected to a plurality of circumferentially arranged fixing blocks, and each detection rod is threadedly connected to the adjacent fixing block.

[0018] With the above solution, the detection rod can be disassembled and replaced by means of the threaded connection between the detection rod and the fixing block.

[0020] Through the above solution, by setting the worm and the worm wheel, the purpose of self-locking the replacement disk can be achieved, and the stability after adjustment can be improved.

[0021] Furthermore, the front ends of the two worms are fixedly connected to the external motor output end, and two groups of connection holes are opened on the upper surface of the connecting plate.

[0022] Through the above solution, by providing the connection holes, it is convenient for the user to connect the connection plate to the external mobile rack.
