Description

Technical Field

[0001] This utility model relates to the field of road engineering quality testing technology, specifically a roadbed compaction testing device for road engineering quality testing. Background Technology

[0002] Compaction degree is one of the key indicators for quality inspection of roadbed filling construction. It characterizes the density after on-site compaction. The higher the compaction degree, the greater the density and the better the overall performance of the material. Currently, the existing compaction degree testing methods in my country usually adopt the ring cutter method, sand cone method, water cone method, nuclear moisture density meter method and compaction meter method, etc. The compaction meter method refers to inserting a test rod with a sensor into the roadbed. The sensor senses the resistance during the insertion process or the mechanical properties of the soil (such as hardness and elastic modulus), and converts it into compaction degree through a preset calibration curve.

[0003] In existing technologies, the detection rod is prone to vibration due to uneven thrust during insertion, which can damage the precision sensor. Furthermore, the lack of effective guidance makes the detection rod prone to tilting during insertion, leading to inaccurate depth measurement, abnormal sensor force, and ultimately, deviations in the detection data, making it difficult to meet the requirements for accurate detection. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figure 1-3 A roadbed compaction testing device for road engineering quality inspection includes a mounting frame 1 and a testing rod 2. A base plate 3 is fixedly installed at the bottom of the mounting frame 1, a linkage plate 4 is provided on the inner side of the mounting frame 1, and a controller 5 is installed on the side of the mounting frame 1. The testing rod 2 is vertically inserted and fixedly installed inside the linkage plate 4. A drive guide mechanism 6 is provided on the mounting frame 1 at a position relative to the linkage plate 4, and adjustment mechanisms 11 are provided on both sides of the mounting frame 1. During testing, the testing rod 2 is fixed on the linkage plate 4, and then the controller 5 is turned on to make the drive guide mechanism 6 work. The drive guide mechanism 6 can apply a downward force to the testing rod 2, so that the testing end of the testing rod 2 is inserted into the roadbed, thereby detecting the roadbed compaction. The adjustment mechanism 11 facilitates the movement of the device.

[0025] The drive guide mechanism 6 includes a first frame 61 fixedly installed on the inner wall of the mounting frame 1. A linkage block 62 is slidably connected to the inner cavity of the first frame 61. One side of the linkage block 62 is fixedly connected to the linkage plate 4. A lead screw 63 is vertically threaded through and threaded to the top of the linkage block 62. One end of the lead screw 63 passes through the outer side of the mounting frame 1. The lead screw 63 and the mounting frame 1 are rotatably connected to the first frame 61. A motor 64 is fixedly installed on the top of the mounting frame 1. The output end of the motor 64 is fixedly connected to one end of the lead screw 63. By turning on the motor 64, the lead screw 63 is rotated, which allows the linkage block 62 to slide within the first frame 61. This causes the linkage plate 4 and the detection rod 2 to move vertically downward, allowing the detection rod 2 to be inserted into the roadbed to detect the compaction degree of the roadbed.

[0026] Furthermore, a second frame 65 is fixedly installed on the inner wall of the mounting bracket 1 relative to the position of the first frame 61. A guide block 66 is slidably connected inside the second frame 65, and one side of the guide block 66 is fixedly connected to the linkage plate 4. When the linkage plate 4 moves downward, it can drive the guide block 66 to slide inside the second frame 65, which can play a guiding role and prevent the detection rod 2 from deviating. A guide groove 67 is fixedly connected to the inner wall of the guide block 66. The guide groove 67 penetrates vertically and slides inside the guide block 66. By setting the guide groove 67, the guide block 66 can be prevented from detaching from the second frame 65, which further improves the stability of the linkage plate 4 when it moves.

[0027] It should also be noted that the top of the linkage plate 4 is provided with an insertion slot 7, and the front surface of the linkage plate 4 is threaded with a bolt 8, the bottom end of which passes through the interior of the insertion slot 7. This arrangement facilitates the disassembly and replacement of the detection rod 2. The surface of the detection rod 2 is fixedly fitted with a limiting block 9, and the bottom of the linkage plate 4 is provided with a limiting groove 10 relative to the limiting block 9. The bottom end of the bolt 8 passes through the interior of the limiting block 9. By setting the limiting block 9 and the limiting groove 10, when the detection rod 2 is inserted into the roadbed, it can be engaged in the limiting groove 10 by the limiting block 9, which can prevent the detection rod 2 from coming out of the insertion slot 7 and increase the stability of the detection rod 2 after it is fixed.

[0028] Furthermore, the adjustment mechanism 11 includes a positioning plate 111 fixedly installed on the side of the mounting frame 1. An electric push rod 112 is fixedly installed at the bottom of the positioning plate 111, and a universal wheel 113 is fixedly connected to the telescopic end of the electric push rod 112. After the test is completed, the electric push rod 112 drives the universal wheel 113 to move downward until the mounting frame 1 is separated from the ground, so as to facilitate the movement of the device. When the test is required, the electric push rod 112 drives the universal wheel 113 to move upward until it is separated from the ground. At this time, the base plate 3 contacts the ground to avoid the device from shifting and causing test errors.

[0029] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
