[0024] The base 1 is arranged in close contact with the ground, and has a large contact area, so that the device is arranged and used with high stability. Preferably, the base 1 can also be reinforced and installed on the ground with components such as bolts, so that it will not be displaced due to vibration during the drilling process. Through the arrangement of the hinge seat 5, the support rod 2 can be rotated relative to the base 1, so that the requirements of the drilling inclination angle can be met when drilling obliquely. The hinge seat 5 can also use components with rotation and connection functions such as ball shafts to ensure the stable arrangement and flexible rotation of the support rod 2.

[0025] The extension rod 3 can be extended or retracted relative to the support rod 2 through the transmission mechanism under the drive of the handle 4, so that the total length of the support rod 2 and the extension rod 3 is slightly smaller than the distance between the ground and the drilling position, and when drilling, the extension rod 3 is extended to meet the drilling distance of the drill rod to complete the drilling operation.

[0026] The mounting base is used to install the drilling rig to ensure the installation and use stability of the drilling rig.

[0027] Please see attached Figure 3 and attached Figure 4 The transmission mechanism includes a transmission box 602, a first transmission assembly and a second transmission assembly; the transmission box 602 is arranged on the support rod 2, the first transmission assembly and the second transmission assembly are arranged in the transmission box 602, and the first transmission assembly is transmission-connected with the second transmission assembly; one end of the handle 4 can be rotatably inserted into the transmission box 602 and is transmission-connected with the first transmission assembly, and the other end of the handle 4 extends in a Z shape to the outside of the transmission box 602; the second transmission assembly is transmission-connected with the extension rod 3.

[0028] The handle 4 can be rotated manually to provide power to the first transmission assembly, so that the first transmission assembly engages with the second transmission assembly, and the second transmission assembly then drives the extension rod 3 to perform telescopic movement relative to the support rod 2. Preferably, when the handle 4 is rotated clockwise, the extension rod 3 extends out of the support rod 2, and when the handle 4 is rotated counterclockwise, the extension rod 3 retracts into the support rod 2.

[0029] Please see attached Figure 3 The first transmission assembly includes a first gear 603 and a third gear 604. The first gear 603 is coaxially fixed to one end of the handle 4. The third gear 604 is rotatably arranged in the transmission box 602 through an axle and is meshed and connected to the first gear 603. The third gear 604 is also connected to the second transmission assembly.

[0030] The handle 4 rotates and drives the first gear 603 to rotate synchronously. The first gear 603 rotates and engages with the third gear 604, so that the third gear 604 rotates and synchronously drives the second transmission assembly.

[0031] Preferably, the diameter of the first gear 603 is larger than the diameter of the third gear 604, so that the handle 4 can be rotated at a smaller angle to drive the extension rod 3 to be retracted and extended into place, and the rotation amplitude of the handle 4 can be reduced by adjusting the transmission gear ratio, making the operation more time-saving and labor-saving.

[0032] Please see attached Figure 3 and attached Figure 4 The second transmission assembly includes a first bevel gear 605, a second bevel gear 606, a worm 607, a worm wheel 608, a second gear 609, a first rotating shaft 610 and a second rotating shaft 601; the first bevel gear 605 is coaxially arranged with the third gear 604, the second bevel gear 606 is coaxially fixedly connected with one end of the worm 607 and meshingly connected with the first bevel gear 605; the other end of the worm 607 is rotatably mounted in the transmission box 602 through the second rotating shaft 601 via a rotating bearing; the first rotating shaft 610 is rotatably mounted in the transmission box 602 via a rotating bearing, the worm wheel 608 and the second gear 609 are both coaxially mounted on the first rotating shaft 610, and the worm wheel 608 is meshingly connected with the worm 607, and the second gear 609 is connected with the extension rod 3.

[0033] The first bevel gear 605 rotates synchronously with the third gear 604 and meshes with the second bevel gear 606. The first bevel gear 605 and the second bevel gear 606 can adopt 45° bevel gears to change the transmission direction, which is convenient for the structural arrangement of the handle 4, the extension rod 3 and the transmission mechanism.

[0034] When the second bevel gear 606 rotates, it drives the worm 607 and the second rotating shaft 601 to rotate synchronously. When the worm 607 rotates, it engages and transmits the worm wheel 608 beside it. When the worm wheel 608 rotates, it drives the first rotating shaft 610 and the second gear 609 installed on the first rotating shaft 610 to rotate synchronously, so that the second gear 609 can transmit the extension rod 3.

[0035] Please see attached Figure 4 A rack 301 is fixedly mounted on the extension rod 3, and openings are formed on the transmission box 602 and the support rod 2 facing the rack 301, so that the end of the second gear 609 extends through the opening to the outside of the transmission box 602 and is meshed and connected with the rack 301.

[0036] The rack 301 is a long strip structure and is arranged along the length direction of the extension rod 3. Under the meshing transmission of the second gear 609 and the rack 301, the rotation of the second gear 609 is converted into axial linear motion of the extension rod 3, so that the extension rod 3 extends out of the support rod 2 or is retracted into the support rod 2.

[0037] Please see attached Figure 3A partition 611 is provided in the transmission box 602, and the first transmission assembly and the second transmission assembly are respectively located on both sides of the partition 611, which facilitates the installation and arrangement of the first transmission assembly and the second transmission assembly, and ensures the independent and safe operation of the first transmission assembly and the second transmission assembly.

[0038] A through hole is reserved on the partition 611 for the common axle of the third gear 604 and the first bevel gear 605 to pass through, and a rotating bearing is connected between the axle and the through hole to ensure stable, smooth and synchronous rotation of the third gear 604 and the first bevel gear 605 relative to the partition 611.

[0039] Please see attached Figure 1 and attached Figure 2 The mounting base includes a cross bar 701 and a fixing piece 702; the cross bar 701 is laterally connected to one side of the upper part of the extension rod 3, so that the cross bar 701 and the upper part of the extension rod 3 form an L-shaped bracket, and the drilling rig is placed on the L-shaped bracket; fixing pieces 702 are provided on the upper part of the extension rod 3 and the cross bar 701, so that the drilling rig is fixed to the L-shaped bracket through two fixing pieces 702.

[0040] Preferably, the extension rod 3 and the cross rod 701 can be made of square steel and welded into an integrated structure, and the support rod 2 can be made of square steel one size larger than the extension rod 3, so that the structure has a strong bearing capacity.

[0041] Preferably, the fixing member 702 can be a U-shaped clamp, which clamps the drill rig and is locked by bolts and nuts to ensure the installation firmness of the drill rig. At the same time, the U-shaped clamps with two different setting directions on the L-shaped bracket provide lateral and vertical limit for the drill rig to ensure the stability of the drill rig during operation.

[0042] Please see attached Figure 1 To Attachment Figure 4 , the method of using the utility model is:

[0043] The base 1 is fixed on the ground below the drilling position. When drilling vertically, the support rod 2 is rotated to a vertical state through the hinge seat 5. When drilling obliquely, the support rod 2 is rotated to a corresponding tilt angle through the hinge seat 5, which can meet the drilling requirements within the range of -90° to 90°. The hinge seat 5 is locked by bolts to keep the support rod 2 at the required angle for drilling.

[0044] The drilling rig is fixed to the L-shaped bracket formed by the cross bar 701 and the upper part of the extension rod 3 through two fixing members 702, and the setting and use stability of the drilling rig is ensured by two fixing members 702 with different setting directions. When installing the drilling rig, the drill rod is set parallel to the extension rod 3, so as to ensure that the drill rod can be driven to move synchronously when the extension rod 3 is extended, and the drill rod can be drilled vertically or obliquely.

[0045] According to the height of the drilling hole, the handle 4 is turned, and the handle 4 drives the first gear 603 to rotate synchronously. When the first gear 603 rotates, it meshes with the second gear 609. When the second gear 609 rotates, it drives the first bevel gear 605 to rotate synchronously. The first bevel gear 605 meshes with the second bevel gear 606. When the second bevel gear 606 rotates, it drives the worm 607 to rotate synchronously. The second shaft 601 rotates relative to the transmission box 602 through the rotating bearing to ensure the stable rotation of the worm 607. When the worm 607 rotates, it meshes with the worm wheel 608. When the worm wheel 608 rotates, it drives the second gear 609 to rotate synchronously through the first shaft 610. The first shaft 610 rotates relative to the transmission box 602 through the rotating bearing to ensure the stable rotation of the first shaft 610. When the second gear 609 rotates, it meshes with the transmission rack 301, thereby driving the extension rod 3 to move axially relative to the support rod 2 through the rack 301 and extend, and the drilling rig is lifted to the drilling height.

[0046] When drilling, as the drill rod is drilled, the handle 4 is slightly rotated to slightly lift the extension rod 3 upward to meet the drilling distance of the drill rod and ensure the shaping effect of the drill hole. Preferably, the power adapter of the drilling rig can be set at a position close to the handle 4 on the transmission box 602 through a wire, so that the construction personnel can control the handle 4 and the drilling rig at the same time.

[0047] After the drilling is completed, the handle 4 is rotated in the opposite direction, and the extension rod 3 is driven to be retracted into the support rod 2 through the first transmission assembly and the second transmission assembly via the rack 301, the drilling rig is lowered below the drilling position, and the mobile device is moved to the next drilling position.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
