Description

Technical Field

[0001] This utility model relates to the technical field of concrete strength testing, and in particular to the technical field of a rebound method testing device for testing the strength of grouting materials used in reinforcement. Background Technology

[0002] Concrete strength is an important indicator, primarily including cubic compressive strength, strength guarantee rate, and axial compressive strength. The rebound method involves striking the concrete surface with a hammer and measuring the distance the hammer bounces back. The rebound value is used as a strength-related indicator to estimate the concrete strength. However, existing rebound method concrete compressive strength testing devices have certain drawbacks. During the rebound test of concrete test blocks, it is necessary to ensure that the rebound hammer is always perpendicular to the concrete surface. Existing rebound hammers rely on manual adjustment to ensure perpendicularity, which introduces errors and leads to inaccurate test results. Furthermore, the device lacks a function to clean up debris. During the test, debris from the test block accumulates near the test site, affecting subsequent testing operations. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the prior art by proposing a rebound method for testing the strength of grouting material for reinforcement. This device can keep the rebound hammer and the testing surface of the grouting material block perpendicular, avoiding the impact of fragments on subsequent testing operations. The testing operation is convenient and the test results are accurate.

[0004] To achieve the above objectives, this utility model proposes a rebound method for testing the strength of grouting material used in reinforcement. The device includes a frame, a fixed platform, locking blocks, a grouting block, a rebound hammer, a testing platform, telescopic locking rods, a buffer spring, an auxiliary support, a positioning bottom ring, an air nozzle, an elastic hose, a compressed air source, a lifting robotic arm, a waste trough, and a touch control center. A fixed platform is located at the lower part of the frame. A grouting block is fixedly mounted on the top of the fixed platform using several locking blocks. A rebound hammer is positioned directly above the grouting block. The top of the rebound hammer is fixedly installed at the bottom of the testing platform. Several telescopic locking rods are evenly and vertically arranged around the rebound hammer at the bottom of the testing platform. An external buffer spring is fitted around the rebound spring. An auxiliary bracket is installed at the bottom of the telescopic sleeve rod. The auxiliary bracket is fitted around the rebound spring. A positioning bottom ring is provided at the bottom of the auxiliary bracket. The auxiliary bracket and the positioning bottom ring are perpendicular to each other. Several air nozzles are arranged around the lower inner side of the auxiliary bracket. The air nozzles are connected to a compressed air source through elastic hoses. A lifting robotic arm is installed on the top of the test platform. A waste trough is detachably installed on the lower side of the fixed platform. A material baffle extends upward from the outer side of the waste trough. A touch control center is provided on the side of the frame. The touch control center is connected to the rebound spring, air nozzles, compressed air source and lifting robotic arm respectively.

[0005] Preferably, the fixed platform is horizontally positioned, and the locking block is fixedly mounted on the fixed platform. The locking block is an L-shaped bolt locking block.

[0006] Preferably, the width of the positioning bottom ring is greater than the thickness of the bottom end of the auxiliary support, and the outer diameter of the positioning bottom ring is greater than the outer diameter of the auxiliary support.

[0007] Preferably, the air nozzle is a duckbill-shaped nozzle, and a flow-stopping solenoid valve is provided at the connection between the air nozzle and the elastic hose.

[0008] Preferably, an electric slider is installed on the top of the lifting robotic arm, and the electric slider is mounted on a translation guide rail, which is fixedly installed on the top of the frame.

[0009] The beneficial effects of this utility model are as follows: This utility model combines a frame, a fixed platform, a locking block, a grouting block, a rebound hammer, a testing platform, a telescopic sleeve rod, a buffer spring, an auxiliary support, a positioning bottom ring, an air nozzle, an elastic hose, a compressed air source, a lifting robotic arm, a waste trough, and a touch control center. Through experimental optimization, it can maintain the perpendicularity of the detection surfaces of the rebound hammer and the grouting block through the support of the auxiliary support. The buffer spring, in conjunction with the telescopic sleeve rod, reduces the impact of the rebound hammer's oscillation during rebound on the stability of the auxiliary support. The detection result has a small error, which helps to improve the detection accuracy. When the auxiliary support detaches from the grouting block, the air nozzle installed at the bottom of the auxiliary support blows the fragments of the grouting block into the surrounding waste trough, preventing the fragments from affecting subsequent detection operations. The detection operation is convenient and the detection results are accurate.
