Description

Technical Field

[0001] The present invention relates to the technical field related to geological sampling, and in particular to a sampling device for tunnel geological detection. Background Art

[0002] Before and during tunnel excavation, various tests are often required. Initial exploration is usually carried out using equipment such as ground-penetrating radar. Before actual construction, due to the attenuation of ground-penetrating radar in the strata, samples must be collected on-site for further physical and chemical testing.

[0003] Obtaining samples from vertical surfaces is an important part of geological testing. It allows staff to analyze vertical rock strength changes, crack development characteristics, water content, and expansive mineral content. This allows for more accurate prediction of landslides, rockbursts, or water gushing risks, and allows for dynamic optimization of support parameters. Existing technologies typically involve manual excavation using a drill rig and manual pushing of materials from the sampling rod, which consumes a lot of manpower. In addition, for different geologies such as soil and rock, drill rods and drill bits of different strengths are usually required, and high-strength accessories cannot generally be simply used because the drill rig required for such a drill rod consumes more power. Therefore, switching between various accessories during sampling is also more troublesome. Summary of the Invention

[0035] like Figures 1 to 3 、 Figure 6 、 Figure 7As shown, the rod transfer unit 3 is arranged at the upper end of the mobile collection unit 1, including a plurality of bases 31 fixed to the upper end surface of the vehicle body 11, a first linear mechanism 32 is provided on the upper end of the base 31, a side frame 321 is provided at the sliding end of the first linear mechanism 32, a second linear mechanism 33 is vertically provided on one side of the side frame 321, a hanger 331 is provided at the output end of the second linear mechanism 33, a third linear mechanism 34 is provided at the lower end of the hanger 331, a hanging plate 35 is provided at the lower end of the sliding end of the third linear mechanism 34, the length direction of the hanging plate 35 is parallel to the travel direction of the third linear mechanism 34, the width direction of the hanging plate 35 is parallel to the output direction of the first linear mechanism 32, and both sides of the two ends of the hanging plate 35 are respectively provided with an inverted An L-shaped frame 351 and a plurality of top frames 352 are further provided on the lower end surface of the hanging plate 35.

[0038] Working method:

[0039] First, the first linear mechanism 32 and the third linear mechanism 34 move the hanging plate 35 to the top of the sampling rod 5 to be used. Then, the second linear mechanism 33 lowers the hanging plate 35 so that the friction wheel 39 abuts against the upper end of the outer periphery of the sampling rod 5. Then, the fourth linear mechanism 36 pushes the vertical plate 37 so that the arc plate 371 clamps the sampling rod 5. In other words, the following is achieved: Figure 1 The status shown.

[0040] Then, the sampling rod 5 is moved by the first linear mechanism 32 and the second linear mechanism 33 so as to be coaxial with the mounting tube 24.

[0042] By analogy, multiple samples are obtained, and then the sampling device for tunnel geological detection drives out of the tunnel, and the staff opens the card plate 16 to obtain the samples for subsequent testing.

[0043] The above are only some of the embodiments listed in this application and are not intended to limit this application.
