Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a sampling device for engineering detection. Background Technique

[0002] Road engineering refers to the processes of planning, designing, constructing, maintaining, and managing roads. During road construction, to ensure that the strength and quality of the constructed road meet the construction requirements and traffic requirements, it is necessary to sample and detect the quality of the constructed road to improve road safety and durability. Sampled soil is divided into disturbed soil and undisturbed soil: Disturbed soil is soil with a damaged natural structure or changed moisture content, often used to determine the particle size composition, particle density, plastic limit, liquid limit, optimal moisture content, shear strength of compacted soil, as well as the content of organic matter and water-soluble salts, etc.; Undisturbed soil is a soil sample that maintains its natural moisture content and natural structure, often used to determine indicators such as soil bulk density, natural void ratio, compression coefficient, and shear strength, etc.

[0003] A Chinese patent with the publication number of CN219862724U discloses a sampling device for engineering detection. In this application, the cleaning pieces on the cleaning device rotate to sweep the stones and weeds on the road to one side, facilitating sampling. The drill bit on the cleaning device is used for pre-drilling, and further sampling is carried out through the sampling device, effectively solving the problem that it is difficult to sample hard soil.

During sampling, the generated vibration easily causes slight displacement of the brake wheel, thereby affecting the vertical downward angle of the drill bit during drilling and causing damage to the drill bit. For this reason, we propose a sampling device for engineering detection. Content of the Utility Model

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] 1. For the sampling device for engineering detection, by starting the second motor to drive the bidirectional threaded rod to rotate, and using the limitation of the limiting rod, the slider drives the first mounting seats to move away from each other, so that the deflection plate deflects, thereby causing the second mounting seat to descend, the support seat to descend, contact the ground, and lift the bottom plate, so as to avoid the moving wheels contacting the ground during sampling, ensure the stability of the device, prevent the device from displacing during sampling, prevent affecting the vertical downward angle of the drill bit during drilling, and avoid damage to the drill bit.

Please refer to Figures 1-4 , which includes a bottom plate 100, moving wheels 200, a handle 300, and a bracket 400;

[0028] Please refer to again Figure 1 , the bottom plate 100 is used to install the moving wheels 200, the handle 300, and the bracket 400;

[0029] Please refer to again Figure 1 , the moving wheels 200 are rotatably connected to the four corner edge positions at the bottom of the bottom plate 100, the handle 300 is fixedly connected to the front and rear parts of the left part at the top of the bottom plate 100, and the front and rear parts of the right part at the top of the bracket 400 are fixedly connected with the bracket 400 for installing an electric telescopic rod 410.

The end of the output shaft of the electric telescopic rod 410 is fixedly connected with a connecting plate 420. The middle of the top of the connecting plate 420 is fixedly connected with a first motor 430. The end of the output shaft of the first motor 430 penetrates through the bottom of the connecting plate 420, and the end of the output shaft of the first motor 430 is fixedly connected with a sampling drill bit 440. The middle of the top of the bottom plate 100 is connected with a support mechanism 500;

[0030] Please refer to again Figure 2 , the support mechanism 500 includes a housing 510, a bidirectional threaded rod 520, a limiting rod 530, a slider 540, a first mounting seat 550, a deflecting plate 560, a second motor 570, a through groove 580, a limiting block 581, a support seat 590, a limiting groove 591, and a second mounting seat 592;

Second mounting seats 592 are fixedly connected to the middle of the left and right sides of the support seat 590.

[0033] In summary, by starting the second motor 570, driving the bidirectional threaded rod 520 to rotate, and using the limitation of the limiting rod 530, the slider 540 drives the first mounting seats 550 to move away from each other, causing the deflection plate 560 to deflect. As a result, the second mounting seat 592 descends, the support seat 590 descends, contacts the ground, and lifts the bottom plate 100, thereby preventing the moving wheels 200 from contacting the ground during sampling, ensuring the stability of the device, preventing the device from displacing during sampling, preventing the angle of the drill bit from deviating vertically downward during drilling, and avoiding damage to the drill bit.

[0034] Please refer to again Figure 2 , the input ends of the electric telescopic rod 410, the first motor 430, and the second motor 570 are all electrically connected to the output end of an external power source, and the end of the output shaft of the second motor 570 is fixedly connected to the left end of the bidirectional threaded rod 520.

[0035] Please refer to again Figure 2 , the slider 540 is slidably connected to the outer side wall of the limiting rod 530, the limiting block 581 is slidably connected to the inside of the limiting groove 591, and the outer side wall of the support seat 590 is attached to the inner side wall of the outer shell 510.

[0037] Please refer to again Figure 4 , a protection mechanism 600 is connected to the middle of the bottom of the connecting plate 420. The protection mechanism 600 includes a fixed shell 610, a connecting rod 620, a moving shell 630, a fixing plate 640, and a connecting spring 650. The fixed shell 610 is fixedly connected to the middle of the bottom of the connecting plate 420. Connecting rods 620 are slidably connected through the front, rear, left, and right parts of the top of the connecting plate 420. The bottom end of the connecting rod 620 is fixedly connected to the moving shell 630. The top ends of the left and right connecting rods 620 are fixedly connected to the fixing plate 640. A connecting spring 650 is sleeved on the outer side of the top of the connecting rod 620.

A notch is formed through the top of the bottom plate 100 corresponding to the bottom position of the moving shell 630.

[0039] In summary, as the electric telescopic rod 410 descends, it drives the connecting plate 420 to descend, causing the moving shell 630 to descend. When the moving shell 630 contacts the ground, the connecting plate 420 continues to descend, so that the moving shell 630 slides outside the fixed shell 610, facilitating the sampling drill bit 440 to contact the ground. Through the setting of the moving shell 630, the sampling drill bit 440 is shielded, preventing dust and impurities from scattering during sampling, ensuring environmental cleanliness, and improving the practicality of the device.

[0040] During specific use, when personnel in the technical field take samples, they start the second motor 570 to drive the bidirectional threaded rod 520 to rotate. With the restriction of the limiting rod 530, the slider 540 drives the first mounting seats 550 to move away from each other, causing the deflecting plate 560 to deflect, so that the second mounting seat 592 descends, the supporting seat 590 descends, contacts the ground, and lifts the bottom plate 100, thus preventing the moving wheels 200 from contacting the ground during sampling and ensuring the stability of the device. Then, they start the first motor 430 to drive the sampling drill bit 440 to rotate, start the electric telescopic rod 410. As the electric telescopic rod 410 descends, it drives the connecting plate 420 to descend, causing the moving shell 630 to descend. When the moving shell 630 contacts the ground, the connecting plate 420 continues to descend, so that the moving shell 630 slides outside the fixed shell 610, and the sampling drill bit 440 contacts the ground for sampling.
