Detailed implementation mode

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

[0039] Example 1:

[0040] This embodiment provides a water drill device. As shown in the figure, it includes a drilling mechanism 6, a robotic arm, a rotary cylinder 2, and a support 1 connected in sequence. Among them, the robotic arm has multiple segments of arms. For example, three segments of arms are adopted, namely the first arm 3, the second arm 4, and the third arm 5 that are hinged in sequence. The first arm 3 is connected to the rotary cylinder 2, and the rotary cylinder 2 is fixed on the upper side of the support 1.

[0041] As Figure 2 shown, the drilling mechanism 6 mainly includes a limit plate 61, a drill barrel 63, a driving component, a guiding component, and a water inlet component. One end of the drill barrel 63 is connected to a 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 plays a supporting role for the drill barrel 63.

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

[0043] A vacuum chamber 62 is provided on the lower side of the containing groove 64. The vacuum chamber 62 is connected to a vacuum pump. When the limiting plate 61 is in contact with the wall, the space between the vacuum chamber 62 and the wall is evacuated by the vacuum pump, that is, by using the vacuum suction cup effect, which facilitates the fixation and alignment of the drill barrel 63.

[0044] In this embodiment, the drilling end of the drill barrel 63 is taken as the front end. The guiding assembly includes a guiding rod 65. One end of the guiding rod 65 is fixed to the back side of the limiting plate 61, and the other end is connected to a fixing rod 71. The guiding rod 65 is located above the drill barrel 63; the driving assembly includes a moving block 67, a driving gear 76, and a rack 75. One end of the rack 75 is fixedly connected to the back side of the limiting plate 61, and the other end is connected to the fixing rod 71. The rack 75 is arranged parallel to the guiding rod 65 and is located below the drill barrel 63.

[0045] The guiding rod 65 passes through the moving block 67, and the moving block 67 is connected to the drill rod 66. A driving gear 76 is installed on the lower side of the drill rod 66 through a driving gear 76 seat. The axis direction of the driving gear 76 is perpendicular to the setting direction of the guiding rod 65. The driving gear 76 meshes with the rack 75. The rotation of the driving gear 76 can drive the moving block 67 to move along the guiding rod 65, so that the drill rod 66 and the drill barrel 63 make a linear motion. The rotation of the driving gear 76 can be realized by a handle 77 or a motor, that is, the rotating shaft of the driving gear 76 is connected to the handle 77 or the motor.

[0046] The rotary drilling of the drill barrel 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. Among them, 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. As Figure 2 shown, the mounting seat 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 barrel 63. 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] As Figure 3 and Figure 4 shown, the drill barrel 63 includes a drill barrel main body. One end of the drill barrel main body is installed with a closing plate, and the other end is an open structure. The open end of the drill barrel main body is provided with protruding portions 631 and recessed portions 632 distributed at intervals. Water outlet holes 633 are arranged at the recessed portions 632. The water outlet holes 633 penetrate along the axial direction of the drill barrel main body. A end cover 661 is also installed at the end of the drill barrel main body where the closing plate is installed. The end cover 661 covers the closing plate, so that each water outlet hole 633 corresponds to the cavity inside the end cover 661. The drill rod 66 is coaxially installed with the end cover 661, and the inside of the drill rod 66 is a hollow structure. 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 barrel 63 drills a hole, a gap is generated between the outer wall of the drill barrel 63 and the inner wall of the hole. After the drill barrel 63 is taken out, an external force is used to apply a lateral force to the outer side of the core sample (such as hammering the outer side of the core sample) until the root of the core sample breaks. At this time, the drill barrel 63 is inserted into the hole again so that the core sample is located inside the drill barrel 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, the arc-shaped pressing piece 131 presses on the outer side of the core sample. When the drill barrel 63 is taken out, the core sample can be taken out at the same time, which is convenient and fast.

[0055] The working principle of this embodiment is as follows:

[0056] The limiting plate 61 is adsorbed on the construction position under the action of vacuum. Under the action of the driving gear 76 and the rack 75, the drill barrel 63 and the drill rod 66 are moved to the target position. The rotating motor 74 is started, and 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 assembly is started to supply water into the drill barrel 63, and the water sprays out from the water outlet hole 633, and the waste water is discharged through the water outlet pipe 78.

[0057] After drilling is completed, first take out the drill barrel 63, apply a lateral force to the side of the core sample with an external force to break the root of the core sample. At this time, the drill barrel 63 enters the hole again so that the core sample enters the drill barrel 63. The arc-shaped pressing piece 131 fits on 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, and multiple arc-shaped pressing pieces 131 press the core sample. 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, the core sample sample.

[0059] Embodiment Two:

[0060] This embodiment provides a water drill device. Compared with Embodiment One, it adds a mobile positioning frame, as Figure 9 and Figure 10 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 cross column 9, a second cross column 10 and a connecting rod 8. The first cross column 9 and the second cross 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] As Figure 9As shown in the figure, 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 end 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 telescoping of the first cylinder 91 can change the angle between the first support column 93 and the first cross-column 9.

[0063] A first universal wheel 92 is installed inside the first support column 93. The first universal wheel 92 is installed near the lower side, that is, away from the connection end with the first cross-column 9. By setting the first universal wheel 92, the frame can move horizontally. For the convenience of fixation, the end of the first support column 93 can also be connected to a bottom column 94, and is fixed to the drilling position through the bottom column 94.

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

[0065] In this embodiment, by setting the moving positioning frame and cooperating with the robotic arm structure, drilling in the vertical and horizontal directions can be achieved, with convenient operation, especially suitable for tunnel construction. The three parts of the moving positioning frame, the robotic arm, and the drilling mechanism 6 can be used in combination or disassembled according to the actual situation, enabling the water drilling device to have multiple functions.

[0066] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
