Description

Technical Field

[0001] The invention relates to the technical field of drilling, in particular to a geotechnical engineering drilling device. Background Art

[0002] Geotechnical engineering investigation is the basis of design and construction. If the investigation is not in place, adverse engineering geological problems will be exposed. Even if the design and construction of the upper structure are of high quality, it will inevitably be damaged. Engineering activities of different types and scales will have different degrees of impact on the geological environment. The purpose of geotechnical engineering investigation is mainly to identify engineering geological conditions, analyze existing geological problems, and make engineering geological evaluations of construction areas. The entire construction process will generate a large amount of dust, polluting the surrounding environment, and the dust is not conducive to the staff's observation of the working status of the drilling equipment. The traditional treatment method is to set up a fan to guide the airflow or choose a fog cannon to reduce dust in the surrounding area. However, this treatment method is carried out when the dust is already in a diffuse state, which will still affect the surrounding environment.

[0003] Chinese invention patent CN118498910B discloses a drilling device for geotechnical engineering construction. Although it can dissipate heat for the drilling unit, prolong the drilling time, avoid dust diffusion, and facilitate construction workers to observe the construction site, when working outdoors, a motor and a water pump are used to provide power for dust reduction. The energy of the internal combustion engine needs to be converted into electrical energy and then used, which will waste a lot of energy. In addition, due to the dust problem, it is easy for electrical components to be damaged, affecting the construction progress. Moreover, when adding or removing drill rods, the existing drilling equipment requires operators to manually lock the lower drill rods. Not only is the operation complicated, but it is also easy for the drill rod to fall due to failure to lock the drill rod due to operational errors, which brings great trouble to the later salvage of the drill rod.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] For an embodiment of the present invention, please refer to Figures 1 to 12 , comprising a base 1 and a lifting assembly 2, the lifting assembly 2 is arranged on the top of the base 1, a driving assembly 3 is arranged inside the lifting assembly 2, a drill rod 5 is installed at the bottom of the driving assembly 3, a rotating disk 4 capable of rotating with the drill rod 5 is arranged in the middle of the base 1 through a bearing 400, a clamping assembly for clamping the drill rod 5 is arranged inside the rotating disk 4, and a dust removal assembly is arranged inside the side wall of the base 1;

[0040] like Figure 8 and Fig. 9As shown, the dust removal assembly includes a dust collection cylinder 801 arranged at the bottom of the base 1, a turbofan 805 for extracting the air inside the dust collection cylinder 801 is arranged inside the base 1, a protective net 106 is arranged at the position where the turbofan 805 exhausts air to the outside, the turbofan 805 is arranged on the inner wall of the base 1 through a rotating cylinder 804, and a filter net 806 is arranged at the position where the dust collection cylinder 801 and the rotating cylinder 804 are connected;

[0041] like Figure 6 and Figure 8 As shown, a circular hole is provided in the middle of the rotating disk 4 for inserting the drill rod 5 downward, a clamping groove 604 is provided on the side wall of the circular hole, a clamping rod 601 is movably connected to the inside of the clamping groove 604 through a rotating shaft, a clamping wheel 602 is provided at the end of the clamping rod 601, and an anti-slip groove is provided on the surface of the clamping wheel 602;

[0042] like Figure 8 and Fig.10 As shown, a clamping cylinder 701 is slidably provided at the bottom of the clamping groove 604, and a reset spring 705 is provided between the clamping cylinder 701 and the clamping groove 604 to move the clamping cylinder 701 toward the center of the rotating disk 4. A clamping tooth 702 is provided on the top of the clamping cylinder 701, and the clamping wheel 602 drives the gear group 613 to rotate through the pulley group 603. When the rotating disk 4 does not rotate, the reset spring 705 pushes the clamping cylinder 701 to connect the clamping tooth 702 with the gear group 613 in power.

[0043] When in use, the drill rod 5 is rotated by the power provided by the driving assembly 3, and at the same time, the lifting assembly 2 makes the driving assembly 3 move up and down to control the lifting and drilling of the drill rod 5. When drilling, since the dust originates from the bottom of the base 1, especially near the drill hole where the dust is the most, the rotation of the turbofan 805 can extract the air inside the dust collection cylinder 801, so that the dust stirred at the bottom of the base 1 is sucked into the dust collection cylinder 801, and the sucked dust is filtered through the filter 806, and then the clean air is discharged through the protective net 106. At the same time, when the drill rod 5 rotates, in order to ensure the stability of the position of the drill rod 5, the drill rod 5 is clamped by the clamping wheel 602, and then the rotating disk 4 can also rotate with the rotation of the drill rod 5;

[0044] When the drill rod 5 needs to be increased or decreased in length, the drill rod 5 will not continue to rotate, and the rotating disk 4 will also stop rotating. Due to the presence of the reset spring 705, the clamping cylinder 701 will be pressed against the gear set 613 so that the gear set 613 is meshed with the reset spring 705. At this time, when the drill rod 5 is moved downward, the rotation of the clamping wheel 602 can enable the gear set 613 to drive the clamping cylinder 701 to move in the direction of clamping the drill rod 5, thereby automatically clamping the drill rod 5, preventing the drill rod 5 left in the borehole from falling when adding or decreasing the drill rod 5, and can effectively avoid the problem of the drill rod 5 falling caused by human error.

[0045] like Figure 1-Figure 4 As shown, the lifting component 2 includes a driving frame 201, a driving motor 203 is arranged on the top of the driving frame 201, the output shaft of the driving motor 203 is keyed to a driving pulley 204, two threaded shafts 206 are symmetrically arranged on the left and right sides of the driving frame 201, a driven pulley 205 connected to the driving pulley 204 through a belt is arranged on the top of the threaded shaft 206, a lifting plate 202 is arranged in the middle of the threaded shaft 206, and the driving component 3 is installed on the lifting plate 202.

[0046] like Figure 2 As shown, the driving assembly 3 includes an engine 301, a reducer 302 is provided on one side of the engine 301, the bottom of the reducer 302 is connected to the drill pipe 5, a generator 303 is provided on one side of the reducer 302, and the generator 303 is electrically connected to the battery that supplies power to the driving motor 203.

[0047] When drilling, the engine 301 provides power, and after the speed is reduced by the reducer 302, a large torque is provided to the drill rod 5. At the same time, the engine 301 can also make the generator 303 work to charge the external battery. When the drill rod 5 needs to move up and down, the battery provides power to control the rotation of the drive motor 203, and the power is transmitted through the active pulley 204 and the driven pulley 205 to drive the threaded shaft 206 to rotate, thereby completing the lifting and lowering control of the drive assembly 3 and the drill rod 5.

[0048] like Figure 2 and Figure 4 As shown, the four corners of the bottom of the base 1 are fixedly connected with lifting columns 103, the bottom of the lifting columns 103 is inserted into the adjusting cylinder 102, an adjusting air bag 104 is arranged between the inner bottom wall of the adjusting cylinder 102 and the lifting columns 103, a control valve 105 that can be connected to an external air pump is arranged on the side of the adjusting air bag 104, and a bottom pad 101 is arranged at the bottom of the adjusting cylinder 102.

[0049] When installing the device, the base 1 is placed in a designated position by hoisting. After the installation is completed, the air pump is connected to the control valve 105 through an air pipe. While measuring with a level meter, the four adjustment air bags 104 are adjusted and inflated to adjust the base 1 to a horizontal state.

[0050] like Figure 6-Figure 7 as well as Fig.11As shown, a compression spring 615 is arranged on the bottom side of the clamping rod 601, and the compression spring 615 presses against the inner wall of the rotating disk 4. When the clamping rod 601 clamps the drill rod 5, the clamping rod 601 can always be pushed to clamp the drill rod 5. When the clamping rod 601 is opened outward, the clamping rod 601 can be kept in a stable open state. A slide groove 614 is arranged in the middle of the clamping rod 601, and a sliding block 614 is arranged inside the slide groove 614 for sliding. 05. The outside of the sliding block 605 is connected to a push-pull rod 607 through a pin shaft, a convex block 608 is provided at the bottom of the push-pull rod 607, a sliding groove 609 matching the convex block 608 is provided at the top of the rotating disk 4, a push-pull rack 610 and a symmetrical rod 611 are symmetrically provided at the end of the push-pull rod 607, a gear ring 612 is provided on the top circumference of the rotating disk 4, and a small gear 405 meshing with the push-pull rack 610 is provided inside the gear ring 612 through a rotating shaft.

[0051] like Figure 5-Figure 7 As shown, the top of the rotating disk 4 is movably connected to a rotating ring 401, the top of the rotating ring 401 is provided with a handle 402 in a ring array, the outer wall of the rotating ring 401 is provided with driving teeth 403, and the bottom of the small gear 405 is provided with a coaxially rotating large gear 404, and the large gear 404 is meshed with the driving teeth 403.

[0052] When in use, after the drill rod 5 is inserted from top to bottom into the circular hole in the center of the rotating disk 4, the handle 402 is manually held to rotate the rotating ring 401, and the driving gear 403 cooperates with the large gear 404 to make the large gear 404 drive the small gear 405 to rotate synchronously, and at the same time, the small gear 405 drives the push-pull rack 610 to move. When the push-pull rack 610 moves, the push-pull rod 607 will push and pull the clamping rod 601. Fig.11 As shown, the sliding block 605 slides inside the sliding groove 614, and the clamping rod 601 also rotates, further compressing the tensioning spring 615. After the tensioning spring 615 reaches a horizontal state, as the clamping rod 601 continues to rotate, the elastic force of the tensioning spring 615 pushes the clamping rod 601 to assist in rotation, thereby providing a clamping force for the clamping rod 601 to clamp on the drill pipe 5.

[0053] like Figure 8 and Fig.10 As shown, a clamping column 703 is slidably arranged inside the clamping cylinder 701, and one end of the clamping column 703 inserted into the clamping cylinder 701 is connected to the clamping cylinder 701 through a ejection spring 706. A rectangular opening is arranged at the bottom of the clamping cylinder 701, and a pressing block 707 is arranged inside the rectangular opening through an elastic plate. A row of locking teeth is arranged at the bottom of the pressing block 707, and a limiting tooth groove 708 cooperating with the locking teeth is arranged on the bottom wall of the clamping groove 604.

[0054] When in use, when the clamping plate 704 is needed to clamp the drill rod 5, the clamping cylinder 701 is driven to move by the descent of the drill rod 5. After the clamping plate 704 touches the drill rod 5, the clamping column 703 will shrink into the inside of the clamping cylinder 701, and the ejection spring 706 will also be compressed, providing a continuous clamping force for the clamping plate 704 to clamp the drill rod 5. At the same time, the end of the clamping column 703 will also press the lower pressing block 707 when moving, and the bottom of the lower pressing block 707 and the limiting tooth groove 708 cooperate to prevent the clamping cylinder 701 from continuing to move. At this time, since the clamping cylinder 701 can no longer move, the clamping wheel 602 will no longer rotate, thereby providing braking force for the descent of the drill rod 5. At the same time, the clamping plate 704 will also clamp the drill rod 5 to prevent the drill rod 5 from falling, thereby achieving the purpose of automatically preventing the drill rod 5 from falling according to the falling movement of the drill rod 5.

[0055] like Figure 8 As shown, a driving gear ring 802 is provided in the middle of the rotating disk 4, and intermediate gears 803 meshing with the driving gear ring 802 are distributed in a circular array inside the base 1, and a gear ring meshing with the intermediate gear 803 is provided on the outer wall of the rotating cylinder 804. When the rotating disk 4 rotates, the driving gear ring 802 drives the intermediate gears 803 distributed in a circular array to rotate at the same time, and the intermediate gears 803 can drive each rotating cylinder 804 to rotate, so that the rotating cylinder 804 rotates at a high speed, and exhaust is performed by using the turbine fans 805 distributed in a circular array.

[0056] like Figure 8 and Fig. 9 As shown, a sliding column 800 is provided at one end of the clamping cylinder 701 connected to the return spring 705. The sliding column 800 passes through the rotating disk 4 and is inserted into the dust collection cylinder 801. A cleaning brush 810 for cleaning the filter 806 is provided at the end of the sliding column 800. An annular opening for accommodating the sliding column 800 is provided on the inner side wall of the dust collection cylinder 801.

[0057] like Figure 8 As shown, dust boxes 807 distributed in a ring array are provided at the position where the dust collection cylinder 801 is connected to the base 1. The outside of the dust collection box 807 is closed by two semicircular sealing sheets 808. The two sealing sheets 808 are detachably connected. The inner and outer walls of the dust collection box 807 and the dust collection cylinder 801 are installed together by internal connecting columns 809 distributed in a ring array.

[0058] When in use, when the drill rod 5 is drilling, since the drill rod 5 can drive the rotating disk 4 to rotate, the driving gear ring 802 can drive the rotating cylinder 804 to rotate through the intermediate gear 803, so that the turbine fan 805 inside the rotating cylinder 804 starts to work and remove dust. In addition, since the drill rod 5 will be lifted up a little before starting to rotate, to prevent the gravel or debris remaining at the bottom of the borehole from directly contacting the drill bit and increasing the rotation resistance, when the drill rod 5 is lifted up, the gear set 613 drives the clamping cylinder 701 to move, and the elastic plate directly connected to the lower pressing block 707 will also deform to adapt to the movement of the clamping cylinder 701. After the clamping cylinder 701 moves, the ejection spring 706 will also eject the clamping column 703. After the clamping column 703 no longer presses the lower pressing block 707, the clamping cylinder 701 recovers its freedom, so that the clamping cylinder 701 can move under the action of the gear set 613, and the clamping cylinder 701 can return to the position where the clamping teeth 702 are just meshed with the gear set 613.

[0059] Subsequently, as the rotation speed of the rotating disk 4 gradually increases, the clamping cylinder 701 moves outward under the action of centrifugal force. When the clamping cylinder 701 is pressed against the inside of the clamping groove 604 to compress the return spring 705 to the shortest value, Figure 8 and Fig. 9 As shown, the sliding column 800 will also move outward to the designated position, so that the end of the cleaning brush 810 is on the filter 806, and the filter 806 distributed in a ring array is cleaned by the rotation of the rotating disk 4. At the same time, driven by the rotating disk 4, the driving gear ring 802 drives the intermediate gear 803 to rotate the rotating cylinder 804, and the turbo fan 805 starts to work, so that the filter 806 can be cleaned at the same time when the dust is removed, so as to achieve the purpose of maintaining the filtering performance and enabling the device to continuously remove dust;

[0060] After the dust attached to the filter 806 is cleaned by the cleaning brush 810, it will fall down into the dust storage box 807. By opening the sealing sheet 808 on the outside of the dust storage box 807, the dust inside can be cleaned.

[0061] The specific steps and principles of this device are as follows:

[0062] First, when installing the device, the base 1 is placed at the designated position by hoisting, and then the lifting assembly 2 is installed. After the installation is completed, the air pump is connected to the control valve 105 through the air pipe, and the four adjustment air bags 104 are adjusted and inflated while measuring with a level meter to adjust the base 1 to a horizontal state;

[0063] Then, the drill rod 5 is installed at the bottom of the driving assembly 3, and the drill bit at the bottom end of the drill rod 5 is inserted into the circular hole in the middle of the rotating disk 4. Then, the rotating ring 401 is rotated by the handle 402, and the driving gear 403 cooperates with the large gear 404 to make the large gear 404 drive the small gear 405 to rotate synchronously. At the same time, the small gear 405 drives the push-pull rack 610 to move. When the push-pull rack 610 moves, the push-pull rod 607 will push and pull the clamping rod 601. Fig.11 As shown, the sliding block 605 slides inside the sliding groove 614, and the clamping rod 601 also rotates, further compressing the tension spring 615. After the tension spring 615 reaches a horizontal state, as the clamping rod 601 continues to rotate, the tension spring 615 pushes the clamping rod 601 to assist in rotation, providing a clamping force for the clamping rod 601 to clamp on the drill rod 5.

[0064] When the drill rod 5 is rotated by the power provided by the driving assembly 3, since the anti-skid grooves are arranged on the surface of the clamping wheel 602, it can rotate along with the drill rod 5 under the action of the clamping force, so that the rotating disk 4 rotates along with it. After the speed increases, the clamping cylinder 701 compresses the reset spring 705 under the action of the centrifugal force. When the clamping cylinder 701 is pressed against the inside of the clamping groove 604 to compress the reset spring 705 to the shortest value, as shown in FIG. Figure 8 and Fig. 9 As shown, the sliding column 800 will also move outward to the designated position, so that the end of the cleaning brush 810 is on the filter 806, and the filter 806 distributed in a ring array is cleaned by the rotation of the rotating disk 4. At the same time, driven by the rotating disk 4, the driving gear ring 802 drives the intermediate gear 803 to rotate the rotating cylinder 804, and the turbo fan 805 starts to work, so that the filter 806 can be cleaned at the same time when the dust is removed, so as to achieve the purpose of maintaining the filtering performance and enabling the device to continuously remove dust;

[0065] When the drill rod 5 rotates at a high speed, the engine 301 provides power, and after the speed is reduced by the reducer 302, a large torque is provided to the drill rod 5. At the same time, the engine 301 can also make the generator 303 work to charge the external battery. When the drill rod 5 needs to move up and down, the battery provides power to control the rotation of the drive motor 203, and the power is transmitted through the active pulley 204 and the driven pulley 205 to drive the threaded shaft 206 to rotate, so as to complete the lifting and lowering control of the drive assembly 3 and the drill rod 5, and the drill rod 5 is continuously moved downward to make the drill bit contact with the ground to be drilled, and the agitated dust is sucked into the dust collection cylinder 801, and falls into the dust storage box 807 under the cleaning of the cleaning brush 810;

[0066] When the drill rod 5 needs to be lengthened, the rotation of the drill rod 5 is stopped. At this time, the clamping tube 701, under the action of the reset spring 705, can make the clamping teeth 702 return to the position where the gear set 613 just meshes. After the top of the drill rod 5 is separated from the driving assembly 3, the driving assembly 3 is lifted to a suitable position. After the drill rod 5 is lengthened, the drill rod 5 is lifted upward again by the lifting assembly 2, and the drill rod 5 is rotated by increasing the speed to shorten the reset spring 705, and then the drill rod 5 is lowered again for drilling.

[0067] When the drill rod 5 needs to be shortened, the driving assembly 3 is lifted by one section through the lifting assembly 2 while rotating the drill rod 5. After the rotation of the drill rod 5 is stopped, the lifting assembly 2 contacts the clamping teeth 702 again, and then the lifting assembly 2 is lowered, so that the gear set 613 drives the clamping cylinder 701 to move, and the drill rod 5 is clamped by the clamping plate 704. After the drill rod 5 is clamped, the pressing block 707 is pressed down to engage with the limiting tooth groove 708 and clamped. At the same time, the gear set 613 can no longer rotate. The clamping plate 704 and the clamping wheel 602 are used to clamp the drill rod 5 to prevent the drill rod 5 from falling, which can further prevent the drill rod 5 from falling into the drilling hole. After the top of the drill rod 5 is disassembled, the height of the driving assembly 3 is lowered, and the height of the driving assembly 3 is raised again. The operation is repeated again, and the drill rod 5 can be disassembled, thereby further preventing the drill rod 5 from falling due to human error.

[0068] After the dust attached to the filter 806 is cleaned by the cleaning brush 810, it will fall down into the dust storage box 807. By opening the sealing sheet 808 on the outside of the dust storage box 807, the dust inside can be cleaned.
