Description

Technical Field

[0001] The present application relates to the technical field of concrete, and in particular to a visual measuring device for concrete slump and spread. Background Art

[0002] Slump is a method and index for determining the workability of concrete. On construction sites and in laboratories, slump tests are usually performed to determine the fluidity of the mixture, supplemented by intuitive experience to assess cohesion and water retention. Slump is a quantitative index to measure the degree of its degree, used to determine whether the construction can proceed normally.

[0003] The slump of concrete is the height difference between the slump cone height and the highest point of the concrete specimen after slumping, and the expansion is the diameter of the concrete expansion after slumping. When measuring the slump or expansion of concrete, it is usually necessary for multiple people to use steel rulers and other tools to measure the result value. When using a steel ruler for measurement, the steel ruler cannot touch the surface of the concrete. Due to the instability of the manual hand, it is difficult to ensure the stability of the steel ruler. Therefore, the measurement effect is not particularly accurate. In addition, when measuring, the person's line of sight must be kept perpendicular to the steel ruler, and then the measurement value is read visually, which makes it difficult to ensure accuracy.

At this time, by turning the two nuts and turning the two nuts on the plug, the position of the measuring plate can be fixed, which is convenient for reading the height of the measuring plate. It has high stability and does not require multiple people to cooperate in operation.

[0018] Optionally, one end of the positioning bolt is in contact with the clamping block.

A vertical plate 3 is fixedly installed on the top outer wall of the base 1, and a long groove 4 for auxiliary sliding is opened on one side outer wall of the vertical plate 3. A sliding block 7 is slidably installed in the long groove 4. By setting the long groove 4, the sliding block 7 can be slidably installed inside. A card block 8 is provided in the sliding block 7, and a measuring plate 5 for measurement is fixedly installed on one side outer wall of the card block 8. By setting the measuring plate 5, it is convenient to measure the height of the concrete. A scale line 6 is opened on one side outer wall of the vertical plate 3. By setting the scale line 6, it is convenient to measure the height of the concrete. A positioning mechanism for positioning is provided on the sliding block 7; by setting the positioning mechanism, it can play a role of positioning and fixing.

[0032] When in use, by moving the measuring plate 5 upwards, the measuring plate 5 moves upwards, thereby driving the sliding block 7 to move along, and moving the measuring plate 5 to the highest point of the spread concrete. At this time, by rotating the two nuts 13 and rotating the two nuts 13 on the plug posts 10, the position of the measuring plate 5 can be fixed, thereby facilitating the reading of the height of the measuring plate 5, with high stability and without the need for multiple people to cooperate in the operation.

[0040] The implementation principle of the present application is as follows: when it is necessary to measure the slump of concrete, first place the base 1 on the side where the concrete has been spread, and then move the measuring plate 5 upwards. The upward movement of the measuring plate 5 will drive the sliding block 7 to move as well, and move the measuring plate 5 to the highest point of the spread concrete. At this time, by rotating the two nuts 13 and rotating the two nuts 13 on the plug posts 10, the position of the measuring plate 5 can be fixed, and then it is convenient to read the height of the measuring plate 5, which has high stability and does not require multiple people to cooperate in the operation; when it is necessary to measure the expansion of concrete, directly take a picture of the concrete through the expansion visual measurement system 2, and the CCD takes a picture of the concrete and generates a picture, which is then transmitted to the PC, and the information is extracted, and the required data is calculated and sent to the PLC, and the PLC matches the received data, and then the expansion of the concrete can be measured, which is simple and convenient;
