DETAILED DESCRIPTION

[0038] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0039] Embodiment 1:

[0040] The present embodiment provides a water drilling device, as shown in the figure, comprising a drilling mechanism 6, a mechanical arm, a rotating cylinder 2 and a support 1 connected in sequence, wherein the mechanical arm has a multi-section arm, for example, a three-section arm, namely a first arm 3, a second arm 4 and a third arm 5 hinged in sequence, the first arm 3 is connected to the rotating cylinder 2, and the rotating cylinder 2 is fixed to the upper side of the support 1.

[0041] like Figure 2 As shown, the drilling mechanism 6 mainly includes a limit plate 61, a drill barrel 63, a driving assembly, a guide assembly, and a water inlet assembly. One end of the drill barrel 63 is connected to the drill rod 66. The limit plate 61 is provided with a through hole, and the drill barrel 63 passes through the through hole and can move relative to the through hole. The limit plate 61 supports the drill barrel 63.

[0042] A receiving groove 64 is provided at the position where the limit plate 61 is installed with the drill tube 63, and a through hole for installing the drill hole is located in the receiving groove 64. The receiving groove 64 is connected to the water outlet pipe 78, and the waste water is discharged by using the receiving groove 64 and the water outlet pipe 78. In this embodiment, the receiving groove 64 is opened along the thickness direction of the limit plate 61, and its bottom surface (the plane located at the lower side of the drill tube 63) is arc-shaped, which is convenient for receiving waste water.

[0043] A vacuum groove 62 is provided at the lower side of the containing groove 64, and the vacuum groove 62 is connected to a vacuum pump. When the limiting plate 61 is in contact with the wall, the vacuum groove 62 and the wall are evacuated by the vacuum pump, that is, the vacuum suction cup effect is utilized to facilitate the fixation and alignment of the drill tube 63.

[0044] In this embodiment, the drilling end of the drill barrel 63 is used as the front end, and the guide assembly includes a guide rod 65, one end of which is fixed to the back side of the limit plate 61, and the other end is connected to the fixed rod 71, and the guide rod 65 is located on the upper side of the drill barrel 63; the driving assembly includes a moving block 67, a power gear 76, and a rack 75, one end of the rack 75 is fixedly connected to the back side of the limit plate 61, and the other end is connected to the fixed rod 71, the rack 75 is arranged parallel to the guide rod 65, and the rack 75 is located on the lower side of the drill barrel 63.

[0045] The guide rod 65 passes through the moving block 67, and the moving block 67 is connected to the drill rod 66. The power gear 76 is installed on the lower side of the drill rod 66 through the power gear 76 seat. The axial direction of the power gear 76 is perpendicular to the setting direction of the guide rod 65. The power gear 76 is meshed with the rack 75. The rotation of the power gear 76 can drive the moving block 67 to move along the guide rod 65, so that the drill rod 66 and the drill barrel 63 can move linearly. The rotation of the power gear 76 can be achieved by a handle 77 or a motor, that is, the rotating shaft of the power gear 76 is connected to the handle 77 or the motor.

[0046] The rotary drilling of the drill tube 63 is realized by a rotating mechanism. In this embodiment, the rotating mechanism includes a rotating motor 74 and a transmission mechanism 73. The rotating motor 74 is connected to the drill rod 66 through the transmission mechanism 73. The drill rod 66 passes through the moving block 67 and the transmission mechanism 73, and the drill rod 66 is connected to the moving block 67 through a bearing. Figure 2 As shown, the mounting base of the rotating motor 74 is fixedly connected to the moving block 67; the transmission mechanism 73 can be a belt transmission mechanism 73, a chain transmission mechanism 73, etc.

[0047] The water inlet assembly is used to supply water to the drill pipe 63, and the water inlet assembly includes a water inlet pipe 72, a water pump 70 and a water tank. One end of the water pipe is connected to the drill rod 66, and the other end is connected to the water pump 70 and the water tank.

[0048] like Figure 3 and Figure 4 As shown, the drill tube 63 includes a drill tube body, a closing plate is installed at one end of the drill tube body, and the other end is an open structure. The open end of the drill tube body is provided with protrusions 631 and grooves 632 that are spaced apart. A water outlet 633 is provided at the groove 632, and the water outlet 633 is provided along the axial direction of the drill tube body. An end cap 661 is also installed at one end of the drill tube body where the closing plate is installed. The end cap 661 covers the closing plate so that each water outlet 633 corresponds to the cavity in the end cap 661. The drill rod 66 is coaxially installed with the end cap 661, and the interior of the drill rod 66 is a hollow structure, and the water inlet pipe 72 is inserted into the drill rod 66.

[0049] Since the drill rod 66 needs to move in the horizontal direction, the water inlet pipe 72 needs to have a certain length to meet the travel requirement of the drill rod 66 .

[0050] The drill tube 63 is equipped with a core sample removal mechanism, such as Figure 5 and Figure 6 As shown, the core sample removal mechanism includes an arc-shaped pressing piece 131, a positioning column 13 and an iris mechanism 11. A plurality of arc-shaped pressing pieces 131 are sequentially arranged along the inner wall of the drill tube 63, and the arc-shaped pressing pieces 131 are arranged at the rear end of the drill tube 63. Each arc-shaped pressing piece 131 is connected to a positioning column 13, and the positioning column 13 passes through the outer wall of the drill tube 63 and is arranged radially along the drill tube 63. The positioning column 13 is connected to the iris mechanism 11, and the ends of adjacent arc-shaped pressing pieces 131 have a certain gap, so that the arc-shaped pressing pieces 131 are driven by the iris mechanism 11 to approach each other to clamp the core sample.

[0051] It should be noted that the positioning column 13 is disposed at a position that is staggered from the water outlet 633 to avoid water leakage.

[0052] like Figure 7 and Figure 8 As shown, the iris mechanism 11 includes an extension arm 12, a rotating plate 111, a positioning plate 112 and a driving assembly. In this embodiment, the positioning plate 112 is a circular plate, and a plurality of rotating shafts are evenly distributed on one side of the surface. Each rotating shaft is connected to a rotating plate 111, and the number of rotating plates 111 corresponds to the number of positioning posts 13. One end of the extension arm 12 is fixed to the rotating plate 111, and the other end is provided with a through hole for the positioning post 13 to pass through. One end of the positioning plate 112 is connected to the rotating shaft, and the other end is an arc surface. When the arc surface of the positioning plate 112 contacts the adjacent positioning plate 112, it reaches the limit position, and the positioning plate 112 no longer rotates.

[0053] The rotating shaft is connected to the driving mechanism, which is installed on the other side of the positioning plate 112, and the rotating shaft is rotated by the driving mechanism. Figure 8 As shown, the driving mechanism includes a synchronous belt 113 and a synchronous pulley 114. The synchronous pulleys 114 correspond to the rotating shafts one by one. Each synchronous pulley 114 is arranged on the inner side of the synchronous belt 113. One of the rotating shafts is connected to the driving motor 116 through another synchronous belt mechanism 115 to realize the synchronous rotation of each rotating shaft.

[0054] After the drill tube 63 drills a hole, a distance is created between the outer wall of the drill tube 63 and the inner wall of the hole. After the drill tube 63 is taken out, an external force is used to apply a lateral force to the outside of the core sample (such as hammering the outside of the core sample) until the root of the core sample breaks. At this time, the drill tube 63 is extended into the hole again, so that the core sample is located inside the drill tube 63. Finally, driven by the drive motor 116, the rotating plate 111 drives the extension arm 12 to move inward. Since the extension arm 12 is connected to the positioning column 13, and the arc-shaped pressing piece 131 is pressed on the outer side of the core sample, when the drill tube 63 is taken out, the core sample can be taken out at the same time, which is convenient and quick.

[0055] The working principle of this embodiment is:

[0056] The limit plate 61 is adsorbed on the construction position under the action of vacuum, and the drill barrel 63 and the drill rod 66 are moved to the target position under the action of the power gear 76 and the rack 75, and the rotating motor 74 is started. The rotating motor 74 drives the drill rod 66 to rotate through the transmission mechanism 73, so that the drill barrel 63 rotates; at the same time, the water inlet component is started to supply water into the drill barrel 63, and the water is sprayed out from the water outlet 633, and the waste water is discharged through the water outlet pipe 78.

[0057] After drilling is completed, the drill barrel 63 is first taken out, and lateral force is applied to the side of the core sample by external force to break the root of the core sample. At this time, the drill barrel 63 enters the borehole again, allowing the core sample to enter the drill barrel 63, and the arc-shaped pressing piece 131 is attached to the outer end side of the core sample. Under the action of the drive motor 116, the rotating rod drives the extension arm 12 to press the positioning column 13 and the arc-shaped pressing piece 131. Multiple arc-shaped pressing pieces 131 press the core sample, and under the action of the drive structure, the core sample is moved out.

[0058] It should be noted that the core sample is irregular after being taken out and does not meet the test requirements. Therefore, it needs to be processed into a standard core sample that meets the specification requirements, that is, a core sample.

[0059] Embodiment 2:

[0060] This embodiment provides a water drilling device, which adds a mobile positioning frame compared to the first embodiment. Fig. 9 and Fig.10 As shown, the support 1 is installed on the mobile positioning frame.

[0061] Specifically, the mobile positioning frame includes a frame body and a moving mechanism installed on the frame body. The frame body plays a supporting role, and its structural form can be set according to actual requirements. In this embodiment, the frame body includes a first horizontal column 9, a second horizontal column 10 and a connecting rod 8. The first horizontal column 9 and the second horizontal column 10 are connected by the connecting rod 8, and the three form an I-shaped structure; the support 1 is fixed on the upper side of the connecting rod 8.

[0062] like Fig. 9As shown, the moving mechanism includes a first moving component, which is symmetrically installed on both sides of the first cross column 9. The first moving component includes a first support column 93. The top of the first support column 93 is hinged to the first cross column 9. A first cylinder 91 is connected between the first support column 93 and the first cross column 9. The extension and retraction of the first cylinder 91 can change the angle between the first support column 93 and the first cross column 9.

[0063] The first universal wheel 92 is installed inside the first support column 93, and the first universal wheel 92 is installed on the lower side, that is, away from the connection end with the first cross column 9; the frame can be moved in the horizontal direction by providing the first universal wheel 92. For the convenience of fixing, the end of the first support column 93 can also be connected to the bottom column 94, and fixed to the drilling position through the bottom column 94.

[0064] Since the drilling position is not fixed, the mobile positioning frame can also have the function of longitudinal movement. Specifically, the second moving assembly is symmetrically installed at both ends of the second horizontal column 10. The second moving assembly includes a second support column 101. The bottom end of the second support column 101 is rotatably connected to the second horizontal column 10. A second cylinder 103 is connected between the two. The second cylinder 103 can change the angle between the second support column 101 and the second horizontal column 10 by telescoping. A second universal wheel 102 is installed on the outer side of the second support column 101.

[0065] This embodiment realizes drilling in the vertical and horizontal directions by setting a mobile positioning frame and cooperating with a mechanical arm structure, which is convenient to operate and is particularly suitable for tunnel construction. The mobile positioning frame, the mechanical arm and the drilling mechanism 6 can be used in combination or separated according to actual conditions, so that the water drilling device has multiple functions.

[0066] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
