Description

Technical Field

[0001] This application relates to the field of mining drilling expansion technology, and more specifically, to a mining energy-saving drilling expansion device. Background Technology

[0002] Mining well reaming is a technique that enlarges the wellbore diameter during drilling using specialized equipment or tools. It is primarily used in mining or formation drilling to meet subsequent construction needs (such as casing installation and cementing). Well reaming is a process in oil drilling engineering that uses specialized tools to enlarge the wellbore diameter. This technique can be divided into two operation modes: reaming while drilling and post-drilling reaming. It is mainly applied to scenarios such as optimizing wellbore structure, preventing wellbore instability, and improving cementing quality.

[0003] Patent document CN106351583B discloses a mining drilling expansion device, which includes a first conveying pipe, a discharge pipe, an upper mounting shaft, a second conveying pipe, a cylinder pipe, a lower chamber conveying pipe, an upper chamber conveying pipe, a conveying pipe, a cylinder, a rotating arm, a rotating blade, an expansion arm, a cylinder motion chamber, an expansion claw, a fixed end cover, a feed inlet, a digging bucket, a connecting shaft, and a flange. The first conveying pipe is installed in the middle position inside the discharge pipe.

[0004] The aforementioned application document describes how the expansion arm drives the expansion claws to open, thereby enlarging the wellbore diameter during drilling. However, when the expansion claws open, the resistance generated by their contact friction with the well wall during wellbore enlargement will cause uneven stress on the rotating drill pipe. This can easily lead to deviation or damage to the drill pipe, making it difficult to reinforce the drill pipe and enhance the stability of drilling. Summary of the Invention

[0043] Example 1, see Figures 1-8This embodiment provides a mining energy-saving drilling expansion device, including a drill string 1, a drill bit 2 fixedly connected to the lower end of the drill string 1 for drilling, and a drill rod 3 fixedly connected to the upper end of the drill string 1. The drill string 1, drill rod 3, and drill bit 2 are hollow, with the hollow portion inside used to discharge drilling and excavation mud and sand. A reinforcing component 4 is provided on the outer surface of the drill rod 3, which is used to reinforce the part of the drill rod 3 near the ground, so that the rotating rod has a support when rotating, enabling the rotating rod to rotate stably. The reinforcing component 4 includes a first electric slide 401, which is U-shaped and has a concave structure on its front. A support component 5 is provided on the back of the first electric slide 401, which is specifically a tracked vehicle and its external attachment. This is a fixed or adjustable device used to move, adjust, and fix the drill string 1, drill rod 3, and drill bit 2. The support assembly 5 includes a vehicle body 501, on which a track assembly is installed for movement (this is prior art). A support plate 502 is hinged to the top of the vehicle body 501. A large hinge seat is provided between the support plate 502 and the vehicle body 501 for supporting and adjusting the support plate 502. A hydraulic push rod 503 is hinged between the support plate 502 and the vehicle body 501. One end of the hydraulic push rod 503 is hinged to the support plate 502, and the other end is hinged to the vehicle body 501. A hydraulic control device is provided on the vehicle body 501 to control the extension and retraction of the hydraulic push rod 503, thereby causing the support plate 502 to adjust its angle on the vehicle body 501. An electric slide rail 504 is fixedly connected to the front of the support plate 502. The electric slide rail 504 is slidably connected to the back of the first electric slide block 401. The electric slide rail 504 is used to drive the first electric slide block 401 to slide and adjust on the support plate 502. This is prior art. A second electric slide block 505 is slidably connected to the front of the electric slide rail 504. The electric slide rail 504 can also drive the first electric slide block 401 to slide and adjust on the support plate 502. A drive assembly 506 is fixedly installed on the inner surface of the second electric slide block 505. The drive assembly 506 is located on the top of the drill rod 3. The drive assembly 506 includes two pneumatic motors and a rotating part for driving the drill rod 3 to rotate. Gears are provided at the output end of the pneumatic motors. Gears are also provided on the outer surface of the rotating part to interact with the gears on the pneumatic motors. The gear meshes with the drill rod 3, and the gear is located within the space on the inner surface of the second electric slide 505. The drive assembly 506 is used to drive the drill rod 3 to rotate, which in turn drives the drill string 1 to rotate the drill bit 2. This is existing technology. Four cylinders 402 are fixedly connected to the outer surface of the first electric slide 401, arranged in pairs on the left and right sides of the first electric slide 401. The output end of each cylinder 402 penetrates and slides through the outer surface of the first electric slide 401. Two reinforcing seats 403 are fixedly connected to the output end of each cylinder 402. The two reinforcing seats 403 are fastened together to form a cylinder that covers and reinforces the drill rod 3. When the drill rod 3 rotates, it slides within the reinforcing seats 403. An expansion assembly 6 is provided on the outer surface of the drill string 1.The expansion assembly 6 is used to open outwards after the drill bit 2 drills, thereby excavating the well wall and expanding the wellbore as the drill bit 2 rotates. The expansion assembly 6 includes four guide rails 601, which are fixedly connected to the outer surface of the drill string 1. A lifting ring 602 is slidably connected to the outer surface of the guide rails 601, which limits the lifting and lowering of the lifting ring 602. Four expansion arms 603 are hinged to the bottom of the lifting ring 602. Specifically, each expansion arm 603 consists of two interlocking cutting walls. The arching of the two cutting walls causes the expansion arms 603 to open. At this time, the outer diameter of the expansion arms 603 is larger than the outer diameter of the drill bit 2, thus cutting the well wall and expanding the wellbore as the drill bit 2 rotates during drilling. The expansion arms 603 and... The drill string 1 is hinged to its outer surface. A pneumatic assembly 7 is installed between the lifting ring 602 and the reinforcing seat 403. The pneumatic assembly 7 is used to drive the expansion assembly 6 to open when the reinforcing assembly 4 reinforces the outer surface of the drill string 3, thereby expanding the wellbore. The pneumatic assembly 7 includes a chamber 701, which is annular and hollow. An annular groove is provided on its top. The chamber 701 is fixedly connected to the outer surface of the drill string 1. A sealing ring 702 is slidably connected to the inner surface of the chamber 701. The sealing ring 702 is slidably connected to the inner surface of the annular groove at the top of the chamber 701. The sealing ring 702 has an I-shaped cross-section. A shaft seal is provided between the sealing ring 702 and the annular groove at the top of the chamber 701. The spacers 701 and 702 can form an effect similar to a central rotary joint. The chamber 701 rotates with the drill string 1, while the closing ring 702 remains stationary. The closing ring 702 rotates within the chamber 701, still sealing the inner surface of the chamber 701. A limit component 10 is provided at the top of the closing ring 702 to limit its rotation and prevent friction between the chamber 701 and the closing ring 702 from causing the chamber 701 to rotate along with it when the drill string 1 drives the chamber 701 to rotate. The limit component 10 includes two metal rings 101, which are fixedly connected to the top of the closing ring 702. The second electric slide 505... An electric winch 102 is fixedly installed on the front. The electric winch 102 is used to wind up the rope. The electric winch 102 has electric drive for winding and releasing and self-locking functions, which is existing technology. The electric winch 102 is connected to the metal ring 101 by a rope. A steel wire rope is connected between the electric winch 102 and the metal ring 101 to pull the closed ring 702 to limit its movement and prevent the rotation of the chamber 701 from causing the closed ring 702 to rotate as well. A second air pressure chamber 703 is fixedly connected to the outer surface of the drill string 1. A second piston rod 704 is slidably connected to the inner surface of the second air pressure chamber 703. The second piston rod 704 is fixedly connected to the top of the lifting ring 602. A connecting pipe 705 is fixedly connected between the second air pressure chamber 703 and the outer surface of the drill string 1. The connecting pipe 705 is L-shaped.There are two components: a second pressure chamber 703, a second piston rod 704, and a connecting pipe 705. The connecting pipe 705 is connected to the chamber body 701. A channel is provided on the inner surface of the drill string 1 for connecting the connecting pipe 705 to the chamber body 701. The air pressure assembly 7 also includes a first pressure chamber 706, which is fixedly connected to the outer surface of the first electric slide block 401. A first flexible hose 707 is connected between the first pressure chamber 706 and the closing ring 702. The first flexible hose 707 is connected to the chamber body 701. The first pressure chamber 706 is connected to the inner surface of the chamber body 701 through the first flexible hose 707. The first flexible hose 707 can be replaced with different lengths to adapt to usage requirements. A first piston rod 708 is slidably connected to the inner surface of the first pressure chamber 706. The first piston rod 708 is U-shaped. There are two components: the first pressure chamber 706, the first piston rod 704, and the first flexible hose 707. The first piston rod 708 is connected to the first... An electric slide block 401 is slidably connected to the outer surface of the reinforcing base 403. A first piston rod 708 is fixedly connected to the outer surface of the reinforcing base 403. A dust-collecting component 8 is mounted on the outer surface of the pneumatic assembly 7 to absorb dust generated during well expansion. The dust-collecting component 8 can be connected to an external vacuum cleaner via a pipe to absorb dust and impurities generated when the expansion assembly 6 excavates the well wall, preventing dust from falling into the hinged motion structure on the expansion arm 603 and getting stuck, thus affecting its reset adjustment. A reminder component 9 is mounted above the lifting ring 602 to alert the user when the expansion assembly 6 is activated. The reminder component 9 illuminates when the expansion assembly 6 opens. If the light does not illuminate after the expansion assembly 6 opens, it indicates a potential problem with the airtightness of the pneumatic assembly 7, preventing the reinforcing assembly 4 from moving and opening the expansion assembly 6 via the pneumatic assembly 7. The reminder component 9 illuminates when the expansion assembly 6 opens while also monitoring the pneumatic assembly 7.

[0044] In practical use, the aforementioned equipment drives the drill rod 3 to rotate via the drive assembly 506. The drill rod 3 drives the drill string 1, causing the drill bit 2 to rotate and thus perform drilling. After the drill bit 2 enters the ground, if it is necessary to expand the wellbore, the cylinder 402 is activated first. The cylinder 402 pushes the reinforcing seat 403 to move towards the drill rod 3 until they make contact. At this time, the two reinforcing seats 403 will merge together to form a cylinder that covers and reinforces the drill rod 3. The rotation of the drill rod 3 will slide within the reinforcing seat 403, thus providing support for the rotation of the drill rod 3. At this time, the movement of the reinforcing seat 403 will also drive the first piston rod 70. 8. The first piston rod 708 pushes the gas in the first pressure chamber 706 to be injected into the chamber 701 through the first hose 707, and then into the second pressure chamber 703 through the channel and connecting pipe 705 opened on the inner surface of the drill string 1. This pushes the second piston rod 704 to extend from the second pressure chamber 703. The second piston rod 704 pushes the lifting ring 602 to descend. The lifting ring 602 pushes the expansion arm 603 to arch. At this time, as the drill string 1 and drill bit 2 rotate, the arched expansion arm 603 will cut the well wall, thereby expanding the well diameter.

[0045] Example 2, see Figures 1-8 The vacuum assembly 8 includes a support base 801, which is J-shaped and fixedly connected to the top of the closing ring 702. A vacuum port 802 is provided on the front of the support base 801 for sucking in dust. A flexible rotating element 803 is rotatably and elastically connected to the support base 801. After rotating on the support base 801, the vacuum port 802 can be reset by the flexible rotating element 803. The flexible rotating element 803 specifically includes an inner shaft and an outer ring. The vacuum port 802 is rotatably connected to the support base 801 via the inner shaft, and the outer ring is fixedly connected to the support base 801. A torsion spring connects the inner shaft and the outer ring for reset. The bottom of the vacuum port 802... The assembly includes a lever 804, a support base 801, a suction port 802, an elastic rotating part 803, and two levers 804, which are respectively located on the front and rear sides of the drill column 1. A lever block 805 is fixedly connected to the outer surface of the drill column 1. The dust collection assembly 8 also includes a tube 806, which is fixedly connected to the front of the support base 801. A second flexible hose 807 is connected between the tube 806 and the suction port 802. A pipe connector 808 is fixedly connected to the top of the tube 806. The pipe connector 808 is used to connect the pipe to an external vacuum cleaner so that the suction port 802 can absorb dust through the external vacuum cleaner. There are two tubes 806, two second flexible hoses 807, and two pipe connectors 808.

[0046] In practical use, when the drill string 1 rotates, it also drives the chamber 701 to rotate. Since a steel cable connects the electric winch 102 to the metal ring 101 on the closed ring 702, the steel cable pulls on the closed ring 702, thus limiting its movement. The rotation of the chamber 701 does not cause the closed ring 702 to rotate together; instead, the chamber 701 rotates on the outer surface of the closed ring 702. This rotation of the chamber 701 drives the lever 805 to continuously push the lever 804, causing the suction port 802 to swing. After block 805 passes lever 804, suction port 802 will reset under the action of elastic rotating member 803. This process repeats, causing suction port 802 to swing continuously when drill string 1 rotates. At this time, the external vacuum cleaner pre-connected to pipe joint 808 is activated. The vacuum cleaner will generate suction force in suction port 802 through pipe body 806 and second hose 807, thereby absorbing the dust generated when the expansion arm 603 cuts the well wall. The continuous swing of suction port 802 can absorb dust more evenly.

[0047] Example 3, see Figures 1-8 The reminder component 9 includes a support platform 901, which is fixedly connected to the right side of the first electric slide 401. A reinforcing rib is provided between the support platform 901 and the first electric slide 401. A warning light 902 is fixedly installed on the top of the support platform 901. A slip ring 903 is fixedly installed on the inner surface of the chamber 701. A brush 904 is fixedly installed at the bottom of the closing ring 702. The brush 904 and the slip ring 903 are slidably connected. The brush 904 and the slip ring 903 are used to transmit power between the rotating and stationary parts of the structure. This is prior art. The brush 904 is electrically connected to the warning light 902. A wire connects the brush 904 and the warning light 902, and this wire passes through the closing ring 702. A seal is provided at the penetration point to ensure the airtightness of the chamber 701. The reminder component 9 also includes a housing 905, which is fixedly connected to the outer surface of the drill string 1. A reinforcing rib is fixedly installed on the bottom of the inner surface of the housing 905. The device is equipped with a power supply 906, which is a battery used to provide power to the warning light 902. A first contact piece 907 is fixedly connected to the right side of the power supply 906. A second contact piece 908 is provided on the top of the first contact piece 907. The second contact piece 908 is L-shaped and elastic. The second contact piece 908 is fixedly connected to the bottom of the inner surface of the housing 905. The second contact piece 908 is electrically connected to the slip ring 903. A wire is connected between the second contact piece 908 and the slip ring 903. The wire passes through the housing 905 and the compartment 701. A seal is provided at the penetration position to ensure the airtightness of the compartment 701. A top rod 909 is slidably connected through the bottom of the housing 905. The top rod 909 is J-shaped and is used to press the second contact piece 908 to deform it so that it contacts the first contact piece 907. The top rod 909 is fixedly connected to the top of the lifting ring 602.

[0048] In practical use, when the lifting ring 602 descends, it also drives the top rod 909 to descend within the housing 905. The top rod 909 actuates the second contact plate 908, causing it to deform and come into contact with the first contact plate 907. At this time, the power supply 906 can connect to the slip ring 903 through the first contact plate 907, the second contact plate 908, and the wire. The slip ring 903 then connects to the warning light 902 through the brush 904 and the wire, illuminating the warning light 902. This causes the lifting ring 602 to illuminate. The descent of 02 causes the expansion arm 603 to open, and the indicator light illuminates as a warning. When there is a problem with the airtightness of the rotating part between the chamber 701 and the closing ring 702, gas leakage causes the second piston rod 704 to fail to fully extend from the second pressure chamber 703. The second piston rod 704 pushes the lifting ring 602 to descend a shorter distance, which prevents the push rod 909 from pushing the second contact plate 908 to contact the first contact plate 907. The warning light 902 will not light up, thus making it easier for the user to diagnose the fault in time.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
