Description

Technical Field

[0001] The utility model belongs to the technical field of Leeb hardness testers, and in particular relates to an auxiliary device for on-site detection of the compressive strength of sleeve grouting materials using a Leeb hardness tester. Background Art

[0002] The Leeb hardness tester is a portable testing instrument used to measure the hardness of metal materials. Its basic principle is to use an impact body with a certain mass to impact the sample surface under a certain test force, measure the impact velocity and rebound velocity of the impact body 1 mm away from the sample surface, and use the principle of electromagnetic induction to induce a voltage proportional to the velocity, thereby calculating the Leeb hardness value.

[0003] However, when the Leeb hardness tester is being tested, the object to be tested should be placed flat on the ground to ensure absolute stability without any shaking. The testing position cannot be suspended in the air, and a support block should be added when necessary. When testing the compressive strength of the sleeve grouting material, the Leeb hardness tester is mostly not vertical but sometimes horizontal. This makes it impossible for the Leeb hardness tester to maintain a vertical angle with the tested surface, resulting in a large difference in the detected values, affecting the testing work.
