Description
Technical Field
[0001] The utility model relates to a detection device, in particular to a concrete quality detection device for highway construction supervision, belonging to the technical field of detection equipment. Background Technique
[0002] The quality detection of concrete is mainly divided into the detection before setting and the detection after setting. The detection before setting includes slump, bleeding rate, uniformity, air content, setting time, water-binder ratio, etc. The detection after setting includes compressive strength, tensile strength, flexural strength, elastic modulus, impermeability, carbonation depth, rebound value, etc. Among them, the detection of slump is an important part. The detection method of slump is to use a specified slump cone, pour concrete into it and tamp it, then pull out the cone vertically upward. The concrete collapses due to its own weight. Subtracting the height of the highest point of the collapsed concrete from the height of the cone is called the slump. During the lifting process of the slump cone, workers cannot apply force evenly to the slump cone, which will lead to inaccurate final test results. According to the Chinese utility model patent (application number: 201820083978.2), a concrete slump test device is disclosed, including a base, a slump cone is abutted on the base, two groups of handles are fixedly connected to the upper end of the slump cone, and the two groups of handles are symmetrical about the axis of the slump cone. A support rod is arranged on the base, and the support rod is perpendicular to the base; the support rods are located on both sides of the slump cone and are symmetrical about the axis of the slump cone. A lifting rod is hinged on the support rod, and the lifting rod is connected to the outer wall of the slump cone, achieving the effect of improving the uniform force of the slump cone during lifting.
[0003] However, this device still has the following problems: This device uses the seesaw principle to lift the slump cone, but two symmetrical lifting rods are used for lifting, so it is necessary to apply force on both sides at the same time, which will also face the problem of uneven force application, resulting in inaccurate final test results.

[0025] To make the technical solutions of the present invention clearer and more definite to those skilled in the art, the present invention will be further described in detail below in conjunction with embodiments and the accompanying drawings. However, the implementation manners of the present invention are not limited thereto.
[0026] As Figures 1-6 shown, the concrete quality detection device for highway construction supervision provided in this embodiment includes a measuring plate 1 and a slump cone 2 located on the top of the measuring plate 1. A lifting mechanism is installed on the top of the measuring plate 1 on one side of the slump cone 2, and a measuring mechanism is provided on the other side of the slump cone 2 on the top of the measuring plate 1.

A funnel 7 is installed on the top of the slump cone 2. The measuring mechanism includes a scale rod 8, a sliding sleeve 9 and a measuring rod 10. The scale rod 8 is rotatably connected to the measuring plate 1. The sliding sleeve 9 is slidably sleeved outside the scale rod 8. The measuring rod 10 is rotatably connected to the sliding sleeve 9.
[0027] Through the setting of the lifting mechanism, rotating the lifting screw 4 can drive the lifting slide bar 5 to move upward, drive the two bearing plates 6 to move simultaneously, and thus drive the slump cone 2 to move vertically upward, avoiding uneven force application and improving the accuracy of the test results. Through the setting of the measuring mechanism, measurement can be carried out to make the measurement results more accurate; at the same time, both the lifting mechanism and the measuring mechanism are rotatably connected to the measuring plate 1. Therefore, when not in use, they can be folded to reduce the occupied space and facilitate storage and carrying.
[0028] In this embodiment, asFigure 1 , Figure 2 and Figure 3 As shown in Figure 1 , Figure 2 and Figure 3 , a mounting groove 101 adapted to the slump cone 2 is formed in the middle of the top surface of the measuring plate 1. A first U-shaped frame 102 located on one side of the mounting groove 101 is fixedly connected to the top of the measuring plate 1. A first rotating hole 103 is formed through the first U-shaped frame 102. An installation hole 104 penetrating the first U-shaped frame 102 is provided on one side of the first rotating hole 103.

During measurement, the measuring rod 10 is rotated to the top of the concrete and then released. The operation is convenient and it is also convenient for storage.
[0034] In this embodiment, as Figures 1-6 shown, the working process of a concrete quality detection device for highway construction supervision provided in this embodiment is as follows:
[0035] Step 1: Rotate the lifting frame 3 to the vertical, insert the pin 105, place the slump cone 2 into the installation groove 101, rotate the slump cone 2 so that the plug rod 202 aligns with the jack 602, then rotate the scale rod 8 to the vertical, unfold the measuring rod 10, and slide the sliding sleeve 9 downward so that the measuring rod 10 is placed on the top of the slump cone 2 and record the height dimension, and then turn the measuring rod 10 to one side;
[0036] Step 2: Install the funnel 7, pour concrete from the funnel 7, use a tamper to tamp, after filling with concrete, remove the funnel 7, level the concrete, rotate the lifting screw 4 to move the lifting slide rod 5 upward, drive the two bearing plates 6 to move simultaneously, thereby driving the slump cone 2 to move vertically upward. After the slump cone 2 is completely separated from the concrete, remove the slump cone 2, and then rotate the measuring rod 10 so that the measuring rod 10 contacts the top of the concrete and record the height dimension;
[0037] Step 3: After the measurement is completed, remove the concrete, rotate the measuring rod 10 to be parallel to the scale rod 8, place it in the storage groove 106, then rotate the bearing plate 6 to be parallel to the lifting frame 3, remove the pin 105, and rotate the lifting frame 3 to fall on the measuring plate 1.
