Description

Technical Field

[0001] The utility model relates to the field of highway detection equipment, in particular to a highway base compaction detection sampling device used for highway construction. Background Art

[0002] Compaction, also known as tamping, refers to the ratio of the dry density of soil or other road construction materials after compaction to the standard maximum dry density, expressed as a percentage. The compaction quality of roadbed and pavement is one of the most important internal indicators of road construction quality management. The compaction degree of roadbed reflects the compactness strength of each compacted layer of the roadbed. Only when the compactness strength of each compacted layer meets the requirements can the overall strength, stability and durability of the roadbed meet the requirements.

DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings and implementation modes. Example 1

[0026] Please refer to Figures 1, 2 and 3, wherein Figure 1 is a schematic structural diagram of a first embodiment of a road base compaction detection sampling device for road construction provided by the utility model; Figure 2 is a schematic structural diagram of a cross-section of a sampling tube shown in Figure 1; and Figure 3 is an enlarged schematic diagram of part A shown in Figure 2. A road base compaction detection sampling device for road construction comprises: a cart 1;

[0027] A mounting frame 2, wherein the mounting frame 2 is fixedly mounted on the top of the cart 1, a first driving motor 4 is fixedly mounted on the top of the mounting frame 2, a threaded sleeve 41 is fixedly mounted on the output end of the first driving motor 4, a first threaded rod 42 is threadedly connected to the inner side surface of the threaded sleeve 41, a mounting frame 43 is fixedly mounted on the bottom of the first threaded rod 42, a limiting plate 44 is fixedly mounted on the bottom of the mounting frame 43, a second driving motor 45 is fixedly mounted on the top of the limiting plate 44, a sampling barrel 46 is fixedly mounted on the output end of the second driving motor 45, and limiting grooves 47 are provided on both sides of the sampling barrel 46;

[0028] An adjusting rod 3, wherein the adjusting rod 3 is threadedly connected to the inside of the top of the mounting frame 2, a first crank 31 is fixedly mounted on the top of the adjusting rod 3, and a baffle 32 is rotatably connected to the bottom of the adjusting rod 3;

[0029] A movable plate 5 is arranged on the inner side surface of the sampling tube 46, and movable blocks 51 are fixedly installed on both sides of the movable plate 5, and a sliding plate 52 is fixedly installed on one end of the movable block 51. A push plate 53 is arranged at the bottom of the movable plate 5, and a rotating cavity 54 is opened at the top of the push plate 53. A rotating groove 55 is opened on the inner side surface of the rotating cavity 54, and a clamping plate 57 is rotatably connected to the inner side surface of the rotating groove 55. A connecting rod 56 is fixedly installed inside the clamping plate 57, and the top of the connecting rod 56 is fixedly installed at the bottom of the movable plate 5.

[0030] A first slide groove 21 is provided on one side of the mounting frame 2, and one end of the limiting plate 44 is slidably connected to the inner side of the first slide groove 21. A second slide groove 22 is provided on the other side of the mounting frame 2, and one end of the baffle 32 is slidably connected to the inner side of the second slide groove 22.

[0031] The baffle plate 32 is disposed on the top of the sliding plate 52 .

[0032] The moving block 51 is slidably connected to the inner side surface of the limiting groove 47 , and the sliding plate 52 is sleeved on the outer side surface of the sampling tube 46 .

[0033] The outer side of the adjusting rod 3 is provided with a thread, and when in use, it can be threadedly connected inside the mounting frame 2, so that when in use, the height of the baffle 32 can be adjusted to meet the use of different sampling tubes 46. When the baffle 32 moves up and down, one end of the baffle 32 slides on the inner side of the second slide groove 22, which can limit the baffle 32.

[0034] One end of the limiting plate 44 slides on the inner side of the first sliding groove 21, and when in use, the limiting plate 44 can be limited to prevent the limiting plate 44 from rotating;

[0035] The sampling tube 46 is installed at the output end of the second driving motor 45, and the sampling tube 46 can be replaced according to the usage;

[0036] Since the bottom of the push plate 53 is lower than the sliding plate 52, when in use, the bottom of the push plate 53 can first touch the ground, and the push plate 53 can rotate on the ground to avoid friction between the sliding plate 52 and the ground.

[0037] The working principle of the highway base compaction detection sampling device for highway construction provided by the utility model is as follows:

[0038] When in use, the user pushes the cart 1 to a suitable position, and then starts the first drive motor 4 and the second drive motor 45, so that the first drive motor 4 drives the threaded sleeve 41 to be threadedly connected to the outer side of the first threaded rod 42, so that the installation frame 43 and the second drive motor 45 move downward, and at the same time, the second drive motor 45 drives the sampling tube 46 to be inserted underground, so that the sampling tube 46 samples the compacted ground, and at the same time, the soil entering the sampling tube 46 pushes the push plate 53 upward;

[0039] After the sampling is completed, the second drive motor 45 is stopped, and then the first drive motor 4 is reversed to move the sampling tube 46 upward. When the sampling tube 46 moves upward, the top of the sliding plate 52 is pressed against the bottom of the baffle 32, so that the baffle 32 limits the sliding plate 52, thereby the pushing plate 53 pushes the soil inside the sampling tube 46 out.

[0040] Compared with the related art, the highway base compaction detection sampling device provided by the utility model for highway construction has the following beneficial effects:

[0041] Through the cooperation of the sampling barrel 46, the first drive motor 4, the threaded sleeve 41, the first threaded rod 42, the second drive motor 45 and the baffle 32, after the sampling is completed, the baffle 32 can limit the sliding plate 52, so that the push plate 53 can push the sample inside the sampling barrel 46 out. In this way, the user does not need to knock on the sampling barrel 46 to discharge the sample inside, which makes it convenient for the user to use, reduces the user's operating steps, and avoids damage to the motor and the sampling barrel 46 caused by knocking.

The second embodiment of the present application provides another road base compaction detection sampling device for road construction. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0043] Specifically, the second embodiment of the present application provides a highway base compaction detection sampling device for highway construction. The difference is that, in a highway base compaction detection sampling device for highway construction, the internal thread at one end of the cart 1 is connected to a second threaded rod 6.

[0044] A second crank handle 61 is fixedly mounted on the top of the second threaded rod 6 .

[0045] A backing plate 62 is rotatably connected to the bottom of the second threaded rod 6 .

[0046] The working principle of the highway base compaction detection sampling device for highway construction provided by the utility model is as follows:

[0047] When performing detection and sampling, the user can rotate the second crank handle 61 so that the second crank handle 61 drives the second threaded rod 6 to be threadedly connected inside the cart 1, and then the bottom of the second threaded rod 6 drives the pad 62 to move downward, so that the bottom of the pad 62 contacts the ground, thereby limiting the position of the cart 1.

[0048] Compared with the related art, the highway base compaction detection sampling device provided by the utility model for highway construction has the following beneficial effects:

[0049] By means of the cooperation between the second threaded rod 6, the second crank handle 61 and the pad 62, when in use, the second crank handle 61 drives the second threaded rod 6 to be threadedly connected inside the cart 1, and then makes the pad 62 contact the ground, so that when sampling is performed, the device can be limited to prevent the device from moving.
