Technical Field

[0001] This utility model relates to the technical field of road compaction measurement equipment, specifically to a road compaction degree measuring device. Background Technology

[0002] Road compaction degree is one of the key indicators for testing the construction quality of roadbed and pavement. It represents the density after on-site compaction. The higher the compaction degree, the greater the density, and the better the overall performance of the material.

[0003] The existing method for measuring road compaction usually involves construction workers inserting a handheld measuring instrument into the ground. However, when inserting the instrument manually, there is an inherent angle deviation, which can affect the accuracy of the test results. Utility Model Content

[0004] The purpose of this invention is to provide a road compaction measuring device to solve the problem that when construction workers insert a handheld road testing instrument into the ground for testing, there will be angular deviations that affect the accuracy of the test results.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A road compaction degree measuring device, further comprising a detector for measuring road compaction degree, including a fixing plate, a fixing cover, a base, a left vertical rod, and a right vertical rod;

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0025] like Figures 1-4 As shown, a road compaction measuring device includes a detector 1 for measuring road compaction, and also includes a fixing plate 2, a fixing cover 3, a base 4, a left vertical rod 5, and a right vertical rod 6;

[0026] The base 4 has a through-hole in the middle, and a left side plate 41 and a right side plate 42 are provided on the left and right sides respectively. The bottom of the left side plate 41 and the right side plate 42 are provided with a tapered rod 43 that is inserted into the ground.

[0027] The left vertical rod 5 is located on the left side of the base 4. The left vertical rod 5 has a track 51 along the vertical direction. Multiple mounting holes 52 are provided on the side wall of the left vertical rod 5, and the left vertical rod 5 has a scale along the vertical direction.

[0028] The right vertical rod 6 is located on the right side of the base 4 and has the same structure as the left vertical rod 5;

[0029] The fixing plate 2 is vertically set, and the left and right sides are respectively provided with connecting sliders 21. The connecting sliders 21 are set in the track 51 and slide up and down. The side wall of the connecting slider 21 is provided with connecting holes 22 that match the mounting holes 52. After the fixing plate 2 is set in position, it is fixed by bolts 7 passing through the mounting holes 52 and connecting holes 22.

[0030] The fixed cover 3 includes a frame 31 and multiple connecting rods 32. The frame 31 is arranged parallel to the front end of the fixed plate 2. The detector 1 is placed vertically behind the fixed plate 2. One end of the connecting rod 32 is connected to the frame 31 and the other end is connected to the fixed plate 2, which is used to fix the detector 1 on the fixed plate 2.

[0031] In this device, the base 4 is placed on the ground. The left side plate 41 and right side plate 42 at both ends of the base 4 serve as extended mounting bases. A tapered rod 43 is installed below the base 4 and is inserted into the ground for fixation, thus fixing the base 4. A left vertical rod 5 and a right vertical rod 6 are installed on the left and right sides of the base 4. After connecting sliders 21 are installed on both sides of the fixing plate 2, the connecting sliders 21 are inserted into the tracks 51 on the left vertical rod 5 and the right vertical rod 6 and slide up and down along the tracks 51. The detector 1 is vertically mounted on the fixed plate 2. The frame 31 of the fixed cover 3 is used to frame the detector 1, and multiple connecting rods 32 are used to connect to the fixed plate 2 to fix the detector 1. The operator slides the left vertical rod 5 and the right vertical rod 6 on the fixed plate 2 up and down by connecting slider 21, and determines the descent height of the detector 1 according to the scale reading at the front end of the left vertical rod 5. Since the middle of the base 4 is through, the detector 1 can be inserted into the ground to perform the test. At this time, the bolt 7 is used to pass through the mounting hole 52 and the connecting hole 22 to fix the height of the fixed plate 2, thus fixing the height of the detector 1. The cooperation between the connecting slider 21 and the track of the left vertical rod 5 and the right vertical rod 6 ensures that the detector 1 is in a vertical state when it moves down and inserts into the ground, ensuring the accuracy of the test.

[0032] like Figure 3 As shown in the preferred embodiment, a support plate 33 is also provided between the frame 31 and the connecting rod 32. In this embodiment, the detector 1 is completely connected through the fixed cover 3. After setting the support plate 33, the weight of the detector 1 can be supported and distributed, so that not only the connecting rod 32 bears the force. In use, multiple support plates 33 can be set, or only one can be set at the bottom to support it.

[0033] like Figure 3 As shown, in a preferred embodiment, the fixing plate 2 and frame 31 are circular, and multiple connecting rods 32 are evenly distributed along the circumference of the frame 31. In this embodiment, since the device uses a WG-VI road compaction tester, and the tester 1 body is circular, setting the fixing plate 2 and frame 31 to be circular adapts to the shape of the tester 1, which reduces material usage and lowers costs while installing and fixing the tester 1.

[0034] like Figure 1 and Figure 4As shown, in a preferred embodiment, it further includes an upper adjusting rod 81, a lower adjusting rod 82, and a moving rod 83. The upper adjusting rod 81 is located at the upper end of the display screen of the detector 1, and its lower end is provided with a first slide rail. The lower adjusting rod 82 is located at the lower end of the display screen of the detector 1, and its upper end is provided with a second slide rail. The moving rod 83 is vertically arranged, with its upper end inserted into the first slide rail and its lower end inserted into the second slide rail. A cleaning cotton 84 is provided at the rear end of the moving rod 83 for cleaning the display screen, and a handle 85 is provided on the side wall. In this embodiment, the detection results of the detector 1 are displayed on the display screen. During use, the operator pulls the handle 85, and the moving rod 83 moves along the first and second slide rails. The cleaning cotton 84 slides to the display screen to clean the stains and dust on the surface of the display screen, ensuring the accuracy of the readings.
