Description

Technical Field

[0001] This invention belongs to the field of geological exploration technology, and specifically relates to a geological exploration borehole enlargement device. Background Technology

[0002] In geological exploration, drilling technology is used to obtain information about underground rocks, soil, and hydrogeology, helping people better understand underground geological structures, lithology, stratum thickness, groundwater levels, and water quality. Drilling technology involves using drilling equipment to drill small-diameter, deep cylindrical holes into the ground. The diameter and depth of the borehole depend on the depth of the geological mineral deposit and the purpose of the borehole. Because the borehole creates small openings, which are inconvenient for construction work and geological sampling, it is necessary to enlarge the borehole. This involves using unique enlargement tools and conventional drill bit procedures to obtain a larger borehole than a conventional one.

[0003] Existing technologies use reaming tools with a single diameter that cannot be adjusted, limiting their use. Different diameter reaming tools are required for holes of different sizes, making them inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a geological exploration borehole enlargement device that can select the required diameter of the enlargement plate as needed, which is convenient to use and has high working efficiency.

[0005] To achieve the above objectives, the present invention provides a geological exploration borehole enlargement device, comprising: a support frame, both sides of which are fixedly connected to the ground, and a lifting device on the support frame; a drilling device, comprising a drill rod and a drive motor, the drive motor being mounted on the lifting device, the drill rod being vertically arranged, the top of the drill rod being fixedly connected to the output shaft of the drive motor and the drive motor being used to drive the drill rod to rotate, and a drill bit for advancing being mounted at the bottom of the drill rod; and a borehole enlargement device, which is mounted above the drill bit, the borehole enlargement device being connected to the support frame via a connector, the borehole enlargement device being sleeved with the drill rod, and a locking device being provided between the borehole enlargement device and the drill rod, the borehole enlargement device comprising multiple enlargement discs of different diameters, each of the multiple enlargement discs comprising a connecting column and multiple enlargement arms radially and evenly distributed around the connecting column.

[0006] Further, the locking device includes: a fixed seat, which is sleeved on the drill rod, with its bottom fixedly connected to the connecting column. The fixed seat is a cylindrical structure with a cavity inside, and a first rack is provided on the surface of the cavity; a clamping member, which is disposed on the upper part of the fixed seat and sleeved with the drill rod, with a spacer between the clamping member and the drill rod, and the clamping member cooperates with the cavity on the fixed seat to clamp the drill rod. A second rack is provided on the plane of the clamping member that contacts the cavity for locking with the first rack; and a locking column, which is disposed outside the fixed seat, with its lower part threadedly connected to the outer side of the fixed seat, and its upper part rotatably connected to the clamping member via a bearing, and the locking column is used to drive the clamping member to move up and down.

[0007] Furthermore, the connector includes a hanging hole and a hook. The hanging hole is located at the end of the reaming arm away from the drill rod. One end of the hook is fixedly connected to the support frame, and the other end of the hook is hooked to the hanging hole.

[0008] Furthermore, the plurality of reaming discs are arranged along the axial direction of the drill rod, and the diameter of the plurality of reaming discs decreases sequentially from top to bottom. The connecting post of each reaming disc is sleeved on the drill rod, and the connecting post is movably connected to the corresponding plurality of reaming arms through a hydraulic telescopic rod.

[0009] Furthermore, the fixed end of the hydraulic telescopic rod is connected to the connecting column, and the movable end of the hydraulic telescopic rod is connected to the reaming arm.

[0010] Furthermore, the hole-expanding device also includes a controller, which is mounted on the support frame and connected to the hydraulic telescopic rod, and is used to control the extension and retraction of the hydraulic telescopic rod.

[0011] Furthermore, the connecting posts of the plurality of reaming discs are detachably connected to the drill rod, and the connecting posts are fixedly connected to the corresponding plurality of reaming arms.

[0012] Furthermore, each of the plurality of borehole-reaming arms is provided with a breaking tooth at its bottom, the plurality of breaking teeth being inclined, and the inclination direction of the plurality of breaking teeth being consistent with the rotation direction of the drill rod.

[0013] Furthermore, the lifting device includes a lifting plate and a hydraulic push rod. The hydraulic push rod is disposed on the upper part of the support frame, and the lifting plate is disposed between the support frame and the ground. The output shaft of the hydraulic push rod passes through the support frame and is fixedly connected to the lifting plate. The hydraulic push rod is used to drive the lifting plate to rise and fall.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. The hole-expanding device used in this invention selects multiple hole-expanding discs of different diameters. When expanding holes, the hole-expanding disc of the appropriate diameter can be selected as needed, which is convenient to use and has a wide range of applications.

[0040] Example 1

[0041] like Figure 1-7As shown, this invention provides a geological exploration borehole enlargement device, comprising: a support frame 1, a drilling device, and an enlargement device. The support frame 1 is fixedly connected to the ground on both sides. A lifting device is provided on the support frame 1. Specifically, the lifting device includes a lifting plate 4 and a hydraulic push rod 2. The hydraulic push rod 2 is disposed on the upper part of the support frame 1, and the lifting plate 4 is disposed between the support frame 1 and the ground. The output shaft of the hydraulic push rod 2 passes through the support frame 1 and is fixedly connected to the lifting plate 4, and the hydraulic push rod 2 is used to drive the lifting plate 4 to rise and fall. The drilling device includes a drill rod 5 and a drive motor 3. The drive motor 3 is disposed on the lifting plate 4 of the lifting device. The drill rod 5 is vertically arranged, and the top of the drill rod 5 passes through the lifting plate 4 and is connected to the output shaft of the drive motor 3. The drive motor 3 is used to drive the drill rod 5 to rotate, and a drill bit 6 for advancing is provided at the bottom of the drill rod 5. The reaming device is located on the upper part of the drill bit 6. The reaming device is connected to the support frame 1 via a connector 10. The reaming device is sleeved with the drill rod 5, and a locking device 9 is provided between the reaming device and the drill rod 5. The reaming device includes multiple reaming discs 7, each with a different diameter. Each reaming disc 7 includes a connecting post 71 and multiple reaming arms 73 radially and evenly distributed around the connecting post 71. The connecting post 71 is a hollow cylindrical structure. Specifically, each of the multiple reaming arms 73 has a breaking tooth 73 at its bottom. The breaking teeth 73 are inclined, and their inclination direction is consistent with the rotation direction of the drill rod 5. As the drill rod 5 rotates, the inclined breaking teeth 73 can more efficiently penetrate the geological soil layers, improving the reaming efficiency.

[0042] Specifically, the locking device 9 includes: a fixed seat 91, which is sleeved on the drill rod 5, with its bottom fixedly connected to the connecting post 71. The fixed seat 91 has a cylindrical structure, with a cavity inside and a first toothed rack 96 on the surface of the cavity. External threads are provided on the outer side of the fixed seat 91. A clamping member 92 is disposed on the upper part of the fixed seat 91 and sleeved with the drill rod 5. A spacer 95 is provided between the clamping member 92 and the drill rod 5. The spacer 95 can be a spring or two semi-circular sleeves. The spacer 95 separates the clamping member 92 from the drill rod 5. The recess on the clamping member 91 is used to clamp the drill rod 5. The clamping member 92 is provided with a second rack 97 on the plane that contacts the recess for locking with the first rack 96. When the clamping member 92 is in contact with the recess of the fixed seat 91, the clamping member 92 and the fixed seat 91 are locked together by the rack to prevent relative sliding. The locking post 93 is located outside the fixed seat 91. The lower inner side of the locking post 93 is provided with an internal thread. The internal thread of the lower part of the locking post 93 is connected to the external thread of the fixed seat 91 by a threaded engagement. The upper part of the locking post 93 is rotatably connected to the clamping member 92 by a bearing 94, and the locking post 93 is used to drive the clamping member 92 to move up and down. By turning the locking member 93, the clamping member 92 on it moves downward and cooperates with the fixed seat 91 to press tightly. As the clamping member 92 moves downward, it gradually hugs the drill rod 5, so that the hole reaming device is locked and fixed to the drill rod 5, thereby performing hole reaming operation.

[0043] The connector 10 is used to temporarily fix the reaming device. The connector 10 is disposed between the reaming disc 7 and the support frame 1. The connector 10 includes a hanging hole 101 and a hook 102. The hanging hole 101 is located at the end of the reaming arm 72 away from the drill rod 5. One end of the hook 102 is fixedly connected to the support frame 1, and the other end of the hook 102 is hooked to the hanging hole 101. During drilling operations, the hook 102 is hooked tightly to the hanging hole 101, so that the reaming device is fixed together with the support frame 1, thereby fixing the position of the reaming device. When the drill rod 5 moves down to drill, the position of the reaming device does not move, so only drilling operations are performed. When reaming is required, the locking pin 93 in the locking device 9 is tightened, so that the clamping member 92 contacts the fixing seat 91 and clamps and locks the drill rod 5, thereby fixing the position of the reaming device on the drill rod 5. Then the hook 102 is removed, and the reaming device can perform reaming operations as the drill rod 5 moves down. By setting the locking device 9, the position between the hole reaming device and the drill rod 5 can be moved relative to each other, so that drilling and hole reaming operations can be carried out separately, and can also be locked and fixed, so that drilling and hole reaming operations can be carried out simultaneously, thus improving the flexibility of the device.

[0044] In this embodiment, multiple reaming discs 7 are arranged along the axial direction of the drill rod 5, and the diameters of the multiple reaming discs 7 decrease sequentially from top to bottom. A connecting post 71 of each reaming disc 7 is sleeved on the drill rod 5, and the connecting post 71 is movably connected to the corresponding multiple reaming arms 73 via a hydraulic telescopic rod 8. Specifically, the fixed end of the hydraulic telescopic rod 8 is hinged to the connecting post 71, and the movable end of the hydraulic telescopic rod 8 is hinged to the reaming arm 73. Since the diameters of the multiple reaming discs 7 are different, a reaming disc 7 of the corresponding diameter is selected according to the required hole size. The reaming arms 73 of the remaining reaming discs 7 are then retracted together using the hydraulic telescopic rod 8. After retraction, the remaining reaming discs 7 form a conical structure. The conical structure at the lower part of the reaming disc 7 of the required diameter provides further propulsion force for reaming, facilitating advancement into the geological structure. Furthermore, since the diameter of each reaming disc 7 is fixed, diameter deviation is less likely to occur during reaming, thus preventing hole deviation.

[0045] In this embodiment, the hole-reaming device further includes a controller 11, which is mounted on the support frame 1. The controller 11 is electrically connected to the hydraulic telescopic rod 8 and is used to control the extension and retraction of the hydraulic telescopic rod 8. The controller 11 can simultaneously retract the hole-reaming arms 72 of the hole-reaming discs 7 other than the hole-reaming disc 7 of the required diameter, thereby improving the convenience of operation.

[0046] In this embodiment, the working principle of the present invention is as follows:

[0047] In use, the hydraulic push rod 2 and drive motor 3 are activated, the lifting plate 4 moves downward, driving the drive motor 3 and drill rod 5 downward. Activating the drive motor 3 causes the drill rod 5 and the drill bit 6 at the end of the drill rod 5 to rotate, enabling drilling and reaming. When reaming adjustment is needed, the locking device 9 is used to lock the drill rod 5 to the reaming disc 7, and the connecting piece 10 between the reaming disc 7 and the support frame 1 is removed. The reaming disc 7 corresponding to the required reaming diameter is selected, and the hydraulic telescopic rod 8 is activated via the controller 11 to retract the reaming arms 73 of the remaining reaming discs 7, forming a conical structure, and pushing downward to create the required diameter hole.

[0048] Example 2

[0049] like Figure 8 , Figure 9 As shown, the geological exploration borehole enlargement device provided in this embodiment is basically the same as that in Embodiment 1, except for the following structural configuration: the connecting posts 71 of the plurality of enlargement discs 7 are detachably connected to the drill rod 5, and the connecting posts 71 are fixedly connected to the corresponding plurality of enlargement arms 73. In use, the enlargement disc 7 of the required diameter can be selected according to the size of the hole, and the selected enlargement disc 7 is fitted onto the drill rod 5 from bottom to top at the drill bit 6 at the bottom of the drill rod 5, thereby achieving diameter adjustment of the enlargement disc 7.

[0050] In this embodiment, the working principle of the present invention is as follows:

[0051] In use, select the reaming disc 7 corresponding to the diameter of the hole to be enlarged, and place the selected reaming disc 7 onto the drill rod 5 from bottom to top at the drill bit 6 at the bottom of the drill rod 5. Use the connector 10 to fix the selected reaming disc 7 to the support frame 1. Start the hydraulic push rod 2 and drive motor 3, the lifting plate 4 moves downward, driving the drive motor 3 and drill rod 5 downward. Start the drive motor 3, and the drill rod 5 and the drill bit 6 set at the end of the drill rod 5 will rotate accordingly, enabling drilling operations. When it is necessary to enlarge the hole, use the locking device 9 to lock the drill rod 5 and the reaming disc 7, and remove the connector 10 between the reaming disc 7 and the support frame 1 to enable hole enlargement operations.

[0052] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Any simple modifications, alterations, or equivalent structural transformations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
