Description

Technical Field

[0001] This utility model relates to the field of highway testing technology, and in particular to a soil condition sampling device for highway construction. Background Technology

[0002] Soil sampling is a crucial step in highway construction, serving as a key component for geological analysis and engineering design. Traditional soil sampling devices often employ fixed or simple support structures, which can lead to poor equipment stability and difficulty in leveling when facing complex terrain and uneven construction surfaces. This can result in sampling deviations or even equipment tipping over, affecting sampling accuracy and operational safety. Furthermore, most devices lack effective adaptive leveling mechanisms, requiring operators to manually raise the equipment or repeatedly adjust support points to achieve balance, which is time-consuming, labor-intensive, and inefficient. Additionally, existing equipment lacks flexibility in switching between movement and positioning and lacks a rapid and stable locking mechanism, making it difficult to meet the efficient and accurate sampling needs of construction sites.

[0003] Therefore, a soil condition sampling device for highway construction is being developed to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing equipment, such as insufficient flexibility in switching between movement and positioning, lack of a fast and stable locking mechanism, difficulty in meeting the efficient and accurate sampling needs of construction sites, and the lack of effective adaptive leveling mechanisms in most devices, which require operators to rely on manual elevation or repeated adjustment of support points to achieve balance, which is time-consuming, labor-intensive, and inefficient, this utility model provides a soil condition sampling device for highway construction.

[0005] The technical implementation scheme of this utility model is as follows:

[0006] A soil sampling device for highway construction includes a mounting frame. A pair of symmetrical hydraulic cylinders are connected to the center of the mounting frame. The telescopic ends of the hydraulic cylinders are oriented upwards, and each telescopic end is connected to a mounting block. A servo motor is connected between the mounting blocks, with its telescopic end oriented downwards. A sampling component is connected to the telescopic end of the servo motor. The sampling component includes a rotating tube connected to the telescopic end of the servo motor. A sampling tube is threadedly connected to the bottom of the rotating tube, and a drill bit is threadedly connected to the bottom of the sampling tube. Both the sampling tube and the drill bit are hollow structures. A horizontal mechanism is provided on the mounting frame for balancing the device and facilitating better sampling.

[0007] As a further preferred embodiment, the leveling mechanism includes lifting columns. The mounting frame has two symmetrically positioned lifting columns slidably connected to its front and rear sides. Each lifting column has a wheel rotatably connected to its bottom. Each lifting column has two housings connected to it, and each housing has a sliding block slidably connected to it. Two springs connect each sliding block to its housing. Each housing has a first pin engaged with a protrusion to assist operation. Each first pin engages with an adjacent sliding block. Each sliding block has a worm gear connected to it. Each housing has a worm wheel rotatably connected to it, and the worm gear meshes with an adjacent worm wheel. A first and second connecting rod rotatably connect the two symmetrically positioned worm wheels at the top, and the two symmetrically positioned worm wheels at the bottom are also rotatably connected by the first and second connecting rods. Adjacent first and second connecting rods are slidably connected. Two levels are connected to the upper side of the mounting frame.

[0008] As a further preferred embodiment, a stabilizing mechanism is also included, which includes rotating blocks. The mounting frame is rotatably connected to the rotating blocks symmetrically arranged front and rear. Each rotating block is fitted with a stabilizing pin, and each rotating block is fitted with a second pin, which is engaged with the adjacent stabilizing pin.

[0009] As a further preferred option, the edges of the mounting frame are chamfered to avoid the risk of scratches to the operator during operation.

[0010] As a further preferred embodiment, each of the lifting columns is equipped with a limiting block to prevent the mounting frame from falling off.

[0011] As a further preferred embodiment, each worm gear is equipped with a booster ball for easy movement.

Detailed Implementation

[0022] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0023] A soil condition sampling device for highway construction, such as Figures 1-7 As shown, the device includes a mounting frame 1 with chamfered edges to prevent operator scratches. A symmetrical hydraulic cylinder 2 is connected to the center of the mounting frame 1, with the telescopic ends of the cylinders facing upwards. Mounting blocks 3 are connected to the telescopic ends of the cylinders 2, and servo motors 4 are connected between the mounting blocks 3. The telescopic ends of the servo motors 4 face downwards, and a sampling component 5 is connected to the telescopic ends of the servo motors 4. The sampling component 5 includes a rotating tube 51, which is connected to the telescopic ends of the servo motors 4. A sampling tube 52 is threadedly connected to the rotating tube 51, and a drill bit 53 is threadedly connected to the sampling tube 52. Both the sampling tube 52 and the drill bit 53 are hollow. A horizontal mechanism 6 is provided on the mounting frame 1 to balance the device and facilitate better sampling.

[0024] The horizontal mechanism 6 includes lifting columns 61. The mounting frame 1 has two symmetrically mounted lifting columns 61 slidably connected at both the front and rear. Each lifting column 61 has a wheel 62 rotatably connected to its bottom. Each lifting column 61 has two outer shells 63 connected to it. Each outer shell 63 has a sliding block 69 slidably connected to it. Two springs 610 are connected between each sliding block 69 and the outer shell 63. Each outer shell 63 has a first pin 67 engaged with it. Each first pin 67 has a protrusion for auxiliary operation. Each first pin 67 engages with an adjacent sliding block 69. Each sliding block 69 has a worm gear connected to it. Each worm gear 66 is equipped with a booster ball for easy movement. Each worm gear 611 is rotatably connected inside the outer casing 63. The worm gear 66 meshes with the adjacent worm gear 611. The two symmetrical worm gears 611 at the top are rotatably connected by a first link 64 and a second link 65. The two symmetrical worm gears 611 at the bottom are also rotatably connected by a first link 64 and a second link 65. The adjacent first link 64 and second link 65 are slidably connected. Two levels 68 are connected to the upper side of the mounting frame 1, and a stabilizing mechanism 7 is also included.

[0025] The stabilizing mechanism 7 includes a rotating block 71. The mounting frame 1 is rotatably connected to a symmetrical rotating block 71. A stabilizing pin 72 is snapped into each rotating block 71. A second pin 73 is snapped into each rotating block 71. The second pin 73 is snapped into the adjacent stabilizing pin 72.

[0026] It should be noted that this device can be used for soil condition sampling during highway construction. First, pull out the second pin 73 to unlock the stabilizing pin 72. Then, slide the stabilizing pin 72 upwards and remove it. Next, push the device to the designated position and insert the stabilizing pin 72 into the rotating block 71. Simultaneously, rotate the rotating block 71 to adjust the appropriate angle to insert the stabilizing pin 72 into the soil. Then, reset the first pin 67 to complete the device fixation. If the road surface is uneven, causing the device to be higher on the left and lower on the right, the first pin should be reset. The interaction between rod 64 and the second connecting rod 65 drives the worm gear 611 to finely adjust the angle. At that time, the two symmetrical first connecting rods 64 at the bottom rotate upward and the second connecting rod 65 rotates downward. Then, the lower side of the mounting frame 1 is lifted upward. Observe whether the level 68 is stable. After it is stable, pull out the second pin 73. At that time, the spring 610 is no longer compressed. The spring 610 rebounds and pushes the sliding block 69 closer to the worm gear 611, so that the worm 66 meshes with the worm gear 611, completing the self-locking and ensuring the stability of the overall device.

[0027] Next, the servo motor 4 is started, causing the output shaft of the servo motor 4 to drive the rotating tube 51 to rotate, which in turn drives the sampling tube 52 to rotate. The drill bit 53 rotates synchronously. Then, the hydraulic cylinder 2 is started, and the output shaft of the hydraulic cylinder 2 is used to move the mounting block 3 downward, so that the drill bit 53 is in contact with the ground and gradually goes deeper into the ground, so that the soil can smoothly enter the sampling tube 52. Then, the sampling tube 52 is lifted out of the ground by the hydraulic cylinder 2. Then, the hydraulic cylinder 2 and the servo motor 4 are turned off, and the sampling tube 52 is manually rotated to remove it from the rotating tube 51. The soil sample is poured out for analysis or preservation.

[0028] It should be noted that when a change of position is required, first pull out the second pin 73 to unlock the stabilizing pin 72, then remove the stabilizing pin 72, then move the sliding block 69 to disengage the worm gear 66 from the worm wheel 611, and insert the first pin 67 into the corresponding housing 63. At that time, the corresponding first connecting rod 64 and second connecting rod 65 will interact with each other, and the mounting frame 1 can continue to move to the next position. For samples that need to be collected from deeper soil layers, the length of the sampling tube 52 can also be increased to meet the needs of deeper soil sampling.

[0029] 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 principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
