Problems solved by technology

[0003] At present, there is no uniform specification and instrument for taking powder from concrete specimens. Most of the existing concrete powder grinding devices have the following problems: (1) The safety is not high during grinding, and it is easy to cause harm to the operator
(2) The positioning accuracy of the powder extraction drill bit on the working surface of the test piece is poor
(3) The powder produced by the specimen during grinding is easy to fly in the air
(4) The collection of each batch of powder will be interfered by other batches of residual powder, which will cause errors in the analysis results
(5) The firmness of the clamping of concrete specimens is poor
(6) Poor ease of use
(7) Indoor noise is loud

Embodiment 2

[0048] A method of drilling powder for an automatic positioning concrete powder extractor based on phased array ultrasonic scanning, comprising the following steps:

[0049] Step 1: The ultrasonic sensor scans the size of the test piece to obtain the side length (length and width) and height of the test block, and sends the side length information of the test block to the powder extraction drill operation controller. The calculation module takes the center of the test block as the coordinate origin, the length direction of the test block as the X axis, the width direction of the test block as the Y axis, and the height direction of the test block as the Z axis to establish a Cartesian coordinate system;

[0050] Step 2: Input the coordinates of the desired powder extraction position from the center of the test piece and the number of required powder extraction points in the powder extraction drill operation controller, and the calculation module in the powder extraction drill o...

Abstract

The invention discloses an automatic positioning concrete powder picking machine based on phased array ultrasonic scanning, and the picking machine comprises a support base, wherein the support base is provided with a vertical lifting rod; the vertical lifting rod is movably connected with a test piece fixing table that is provided with a vertical and horizontal moving mechanism, and the verticaland horizontal moving mechanism is provided with an adjustable clamping block; the top end of the vertical lifting rod is further provided with a mounting platform, a powder picking bit operation controller is arranged below the mounting platform, a powder picking bit is disposed below the powder picking bit operation controller, and an ultrasonic scanner is disposed on the powder picking bit; anautomatic powder collector is disposed adjacent to the powder picking bit and connected to the mounting table; and the powder picking bit operation controller comprises an external powder picking bitoperation module screen and an internal calculation module. The concrete powder picking machine is high in safety, can automatically locate and take powder, and has high drilling accuracy, high powderpicking efficiency, simple operation and low labor intensity.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to an automatic positioning concrete powder extractor based on phased array ultrasonic scanning. Background technique [0002] Concrete structures often fail to reach the expected service life due to carbonization, chloride ion intrusion, acidic medium corrosion, etc. In order to study its failure mechanism, it is necessary to take powder from cubic concrete specimens in the laboratory, and chemically react the powder to determine changes in its composition. It is worth noting that there are high requirements for the depth, path, and relative position of each powder extraction. [0003] At present, there is no uniform specification and instrument for taking powder from concrete specimens. Most of the existing concrete powder grinding devices have the following problems: (1) The safety is not high during grinding, and it is easy to cause injury to the operator. (2) The po...
