[0029] The embodiment of the present application provides a geological exploration drilling anti-dumping device, such as Figure 1As shown, it includes a bottom ring plate 100, a plurality of fixed wedges 200, a clamping cylinder 300 and a plurality of arc-shaped clamping plates 400, wherein the bottom ring plate 100 is a structure for installing and supporting other components, the fixed wedges 200 can fix the bottom ring plate 100 on the ground, the clamping cylinder 300 is a component for accommodating drilling equipment, and the arc-shaped clamping plate 400 can clamp the drilling equipment to keep the drilling equipment stable.

[0030] like Figure 2 As shown, the bottom ring plate 100 is provided with a plurality of fixing holes 110 , and the plurality of fixing holes 110 are evenly distributed along the circumference of the bottom ring plate 100 . The bottom ring plate 100 can be fixed by the cooperation of the fixing holes 110 and the fixing wedges 200 .

[0031] like Figure 1 As shown, the number of the plurality of fixing wedges 200 is equal to the number of the plurality of fixing holes 110. The plurality of fixing wedges 200 pass through the plurality of fixing holes 110 one by one and are inserted into the soil. The fixing wedges 200 are inserted into the soil to fix the bottom ring plate 100. Generally, the bottom end of the fixing wedge 200 forms a sharp angle to facilitate insertion into the soil.

[0032] like Figure 2 As shown, the clamping tube 300 is arranged on the bottom ring plate 100 and is coaxial with the bottom ring plate 100. The tube wall of the clamping tube 300 is provided with a plurality of threaded holes 310. The plurality of threaded holes 310 are evenly distributed along the circumference of the clamping tube 300. The drilling tube of the drilling equipment is inserted into the clamping tube 300.

[0033] like Figure 1 As shown, the number of the plurality of arc-shaped clamping plates 400 is equal to the number of the plurality of threaded holes 310, and the outer side of the arc-shaped clamping plate 400 is rotatably connected with a screw rod 500, and the plurality of screw rods 500 are matched with the plurality of threaded holes 310 in a one-to-one manner. When the screw rod 500 rotates, the arc-shaped clamping plate 400 approaches or moves away from the center of the clamping tube 300. By rotating the screw rod 500, the arc-shaped clamping plate 400 can be brought close to the center of the clamping tube 300 until it is clamped on the outer wall of the drilling tube of the drilling equipment, thereby clamping and supporting the drilling tube of the drilling equipment, and the drill rod of the drilling equipment can be drilled in the drilling tube.

[0034] like Figure 1 As shown, a first shock-absorbing pad 600 is provided on the inner side of the arc-shaped clamping plate 400. When clamping, the first shock-absorbing pad 600 directly abuts against the drilling tube of the drilling equipment. The vibration generated when the drilling equipment is working can be absorbed by the first shock-absorbing pad 600, thereby reducing the transmission of vibration. The first shock-absorbing pad 600 can be detachably connected to the inner side of the arc-shaped clamping plate 400, and when the first shock-absorbing pad 600 is damaged, it is convenient to replace.

[0035] When in use, the bottom ring plate 100 can be fixed on the ground through the fixing hole 110 and the fixing wedge 200, thereby fixing the entire device. The drilling equipment is placed in the clamping cylinder 300, and the screw 500 is adjusted to make the multiple arc-shaped clamping plates 400 approach the center of the clamping cylinder 300 until the arc-shaped clamping plates 400 are clamped on the drilling equipment to clamp the drilling equipment, and the first shock-absorbing pad 600 on the inner side of the arc-shaped clamping plate 400 directly contacts the drilling equipment, so that the vibration generated by the drilling equipment can be absorbed.

[0036] Compared with the prior art, the geological survey drilling anti-dumping device can achieve good clamping of the drilling equipment and fix the drilling equipment. The first shock-absorbing pad 600 inside the arc-shaped clamping plate 400 directly contacts the drilling equipment, and the vibration generated by the drilling equipment can be absorbed, thereby reducing the transmission of the vibration to the arc-shaped clamping plate 400, the clamping tube 300, etc., so that the entire anti-dumping device remains stable, the soil is not easy to loosen, and the anti-dumping effect is good.

[0037] In some embodiments, Figure 3 As shown, the outer side of the arc-shaped clamping plate 400 is provided with a receiving hole 410, the opening of the receiving hole 410 is provided with an annular baffle 420, and the end of the screw 500 close to the arc-shaped clamping plate 400 is provided with a circular plate 510, the screw 500 is arranged through the annular baffle 420, the circular plate 510 is located in the receiving hole 410, and the inner diameter of the annular baffle 420, the diameter of the circular plate 510 and the aperture of the receiving hole 410 increase in sequence. In this structure, when the screw 500 rotates, the circular plate 510 is driven to rotate, which can push the bottom of the receiving hole 410 or pull the annular baffle 420, thereby driving the arc-shaped clamping plate 400 to move.

[0038] In some embodiments, Figure 2 As shown, the bottom surface of the bottom ring plate 100 is provided with a strip protrusion 120, and the strip protrusion 120 extends in the radial direction of the bottom ring plate 100. There are multiple strip protrusions 120, which are evenly distributed along the circumference of the bottom ring plate 100. When the bottom ring plate 100 is fixed to the ground, the strip protrusions 120 can be embedded in the soil, so that the friction between the entire bottom ring plate 100 and the ground is increased, the bottom ring plate 100 is easier to maintain stability, and the anti-dumping effect is better.

[0039] In some embodiments, Figure 4 As shown, a top ring plate 320 is provided at the top of the clamping tube 300, and a plurality of connection holes 330 are provided on the top ring plate 320. A flange can be provided on the drilling tube of the drilling equipment. When the drilling tube is inserted into the clamping tube 300, the flange can be connected with the top ring plate 320 through the connection holes 330 and bolts, and then the screw 500 is rotated to clamp the drilling tube with the arc-shaped clamping plate 400. The drilling tube is fixed by clamping and flange connection, and the fixing effect is better, thereby ensuring the drilling effect.

[0040] In some embodiments, Figure 4 As shown, a second shock-absorbing pad 340 is provided on the upper surface of the top ring plate 320, that is, when the flange is connected to the top ring plate 320, the second shock-absorbing pad 340 is located between the two, which can absorb the vibration generated by the drilling tube, reduce the transmission of vibration, and have a better anti-dumping effect.

[0041] In some embodiments, two locking nuts are provided on the screw rod 500, and the two locking nuts are respectively abutted against the inner wall and the outer wall of the clamping tube 300. After the arc-shaped clamping plate 400 is clamped to the drilling equipment, the locking nuts can be adjusted so that the locking nuts abut against the inner wall and the outer wall of the clamping tube 300, so as to achieve the locking of the screw rod 500 and a better clamping effect.

[0042] In some embodiments, Figure 1 As shown, a cover plate 210 is provided at the top of the fixing wedge 200, and the cover plate 210 abuts against the bottom ring plate 100, and the cover plate 210 can cover and press the bottom ring plate 100, and has a better fixing effect on the bottom ring plate 100. The cover plate 210 is rotatably connected with a lifting ring 220, and when disassembling, the fixing wedge 200 can be pulled out through the lifting ring 220, which is easier to disassemble.

[0043] In some embodiments, the thickness of the first shock absorbing pad 600 is 5 mm to 10 mm. Compared with the case where the thickness is less than 5 mm, the first shock absorbing pad 600 in this range is thicker, has better shock absorption effect, and has a longer service life. Compared with the case where the thickness is greater than 10 mm, the first shock absorbing pad 600 in this range is thinner and has a lower cost.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
