Embodiment 1

[0040] Such as figure 1 As shown, an automatic positioning and dotting device for a concrete rebound tester includes a base 2 and a rebound tester 1, a mounting arm 3 is arranged horizontally on the base 2, and a rotating rod 4 is arranged on the mounting arm 3 to rotate perpendicularly to the direction of the mounting arm 3 , the mounting arm 3 is provided with a driving assembly 5 for driving the rotating rod 4 to rotate in a vertical plane.

[0041] Such as figure 1 As shown, the driving assembly 5 includes a first worm gear 51, a first worm screw 52, ​​a rotating block 53 and a driving motor 54. The first worm gear 51 is rotatably sleeved at one end of the mounting arm 3, and the driving motor 54 is fixedly arranged on the mounting arm 3. The driving motor 54 is a servo motor, so as to control the rotation angle precisely. The first worm 52 is fixed coaxially on the output shaft of the drive motor 54 and meshes with the first worm wheel 51. The rotating block 53 is fixed...

Embodiment 2

[0056] A method for automatic positioning and dotting of a concrete rebound tester. First, a measurement area is set, including 16 measurement points, and the 16 measurement points are divided into grids by a scribe pen. Each grid is a square, and every four measurements The points are a group, and then control the rebound hammer 1 to realize the positioning of the four measurement points of each group along the set motion trajectory, and then control the rebound hammer 1 to perform spot measurement on the four measurement points of each group at the same time rebound value.

[0057] The measurement area is divided into grids, and there are nine grids in three rows and three columns. The grids are square. When measuring, measure the grids located at the four corners of the measurement area in turn. Four groups of measurements complete a measurement area 16 The measurement work of each measurement point has high measurement efficiency and accuracy.

Abstract

The invention relates to anautomatic positioning striking device and method ofa concrete rebound instrument, and belongs to the technical field of concrete detection. The automatic positioning striking device ofthe concrete rebound instrumentcomprises a base and rebound instruments, a mounting arm is horizontally arranged on the base, a rotating rod is rotatably arranged on the mounting arm, a driving assembly is arranged on the mounting arm, and a driving source is arranged on the base; a mounting bracket is fixedly arranged on the rotating rod, four mounting parts are arranged on the mounting bracket, a rebound instrument is mounted on each mounting part, and the length directionsof the rebound instrumentsis parallel to the mounting arm. The driving source drives the mounting arm to movetoward the direction near the wall surface, so that the rebound instruments contact with the wall surface and complete a rebound test; then the driving assembly drives the rotating rod to rotate in the vertical plane, and then the rebound test is conducted,the process is carried out four times successively, and the rebound test of 16 to-be-tested points in a to-be-tested area can be completed; and measurement is convenient, and measurement efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of concrete detection, in particular to an automatic positioning and dotting device and method for a concrete rebound tester. Background technique [0002] Using a rebound tester to test the compressive strength of concrete is the most widely used non-destructive testing method for concrete construction site testing in our country. [0003] The national industry standard JGJ / T23-2011 "Technical Regulations for Testing the Compressive Strength of Concrete by Rebound Method" stipulates that when testing concrete components in batches, components should be randomly selected, and the number of sampling inspections should not be less than 30% of the total number of components in the same batch. Less than 10 pieces; for general components, the number of measurement areas should not be less than 10; and each measurement area should read 16 rebound values. This requires thousands of bullets for each batch of tests....
