Description

Technical Field

[0001] This application relates to the technical field of reverse-lifting drilling rigs, and particularly to a quick-disassembly and assembly drill pipe for a reverse-lifting drilling rig and a method for quickly disassembling and assembling the drill pipe. Background Art

[0002] In the construction of inclined shafts and vertical shafts of pumped-storage power stations, reverse-lifting drilling rigs and drill pipes play a crucial role; currently, threaded connection methods are commonly used between drill pipes to achieve connection and fixation; however, threaded connections require tools to be tightened, which not only increases the complexity of construction but also prolongs the operation time; moreover, during the process of driving by thread locking, the threaded part is prone to damage. Once the thread is damaged, the structural integrity and connection reliability of the drill pipe will be severely affected, and even the entire drill pipe device may become unusable, increasing the construction cost and maintenance difficulty; the disassembly process of the threaded connection of the drill pipe is also cumbersome, requiring tools to reverse-loosen the thread, but the damaged thread makes the drill pipe difficult to disassemble, increasing the work intensity and safety risk of construction workers. Summary of the Invention

[0003] To improve the defects that the disassembly and assembly of the threaded connection between drill pipes on a reverse-lifting drilling rig are inconvenient and prone to damage, this application provides a quick-disassembly and assembly drill pipe for a reverse-lifting drilling rig and a method for quickly disassembling and assembling the drill pipe.

[0004] The quick-disassembly and assembly drill pipe for a reverse-lifting drilling rig and the method for quickly disassembling and assembling the drill pipe provided by this application adopt the following technical solutions:

[0005] A quick-disassembly and assembly drill pipe for a reverse-lifting drilling rig includes a first drill pipe, a second drill pipe axially corresponding to the first drill pipe, a first clamping mechanism connected to the end of the first drill pipe and used for clamping the end of the second drill pipe, a second clamping mechanism connected to the end of the second drill pipe and used for clamping the end of the first drill pipe, a first connection mechanism inserted into the first drill pipe in the radial direction and used for connecting the first drill pipe and the first clamping mechanism, and a second connection mechanism inserted into the second drill pipe in the radial direction and used for connecting the second drill pipe and the second clamping mechanism;

[0006] A connection shaft sleeve is provided at the end of the first drill pipe, and a connection shaft rod for inserting into the connection shaft sleeve is provided at the end of the second drill pipe;

[0007] The first clamping mechanism includes a moving shaft assembly movably inserted into the first drill pipe, and a first clamping link assembly hinged to the moving shaft assembly;

[0008] The second clamping mechanism includes a moving shaft sleeve assembly movably inserted into the second drill pipe, a second clamping link assembly hinged to the moving shaft sleeve assembly, and magnetic attraction components respectively arranged on the connecting shaft sleeve and the moving shaft sleeve assembly. The magnetic attraction components are used for the ends of the connecting shaft sleeve and the moving shaft sleeve assembly to be mutually attached and adsorbed.

[0009] When the connecting shaft rod is inserted into the connecting shaft sleeve, the connecting shaft rod presses against the moving shaft assembly, and the moving shaft assembly drives the first clamping link assembly to flip and clamp the second drill pipe.

[0010] When the connecting shaft rod is withdrawn from the connecting shaft sleeve, the connecting shaft sleeve adsorbs and pulls the moving shaft sleeve assembly, and the moving shaft sleeve assembly drives the second clamping link assembly to flip and clamp the first drill pipe.

[0011] By adopting the above technical solution, when the connecting shaft rod is inserted into the connecting shaft sleeve, the connecting shaft rod presses against the moving shaft assembly, and the moving shaft assembly drives the first clamping link assembly to flip and clamp the second drill pipe. The first connecting mechanism connects the first drill pipe and the moving shaft assembly. When the first drill pipe pushes the second drill pipe to move downward, the connecting shaft rod and the moving shaft assembly maintain a mutually pressing trend, so that the first clamping link assembly maintains a trend of clamping the second drill pipe.

[0012] When the second clamping link assembly clamps the first drill pipe, the second connecting mechanism connects and fixes the second drill pipe and the moving shaft sleeve assembly. When the first drill pipe and the second drill pipe move upward, the connecting shaft sleeve adsorbs and maintains a trend of pulling the moving shaft sleeve assembly, and the moving shaft sleeve assembly drives the second clamping link assembly to flip and maintain a trend of clamping the first drill pipe.

[0013] So that when the first drill pipe and the second drill pipe move up and down, they can be tightly connected and not easily separated. And when it is necessary to separate the first drill pipe and the second drill pipe, directly disassemble the first connecting mechanism and the second connecting mechanism, pull the first clamping link assembly away from the second drill pipe, pull the second clamping link assembly away from the first drill pipe, and synchronously separate the first drill pipe and the second drill pipe. The present application realizes rapid and stable clamping and release between drill pipes through the first clamping mechanism and the second clamping mechanism, avoiding the problem of thread damage. The clamping and release operations between the first drill pipe and the second drill pipe of the present application are simple and do not require tool assistance, greatly reducing the operation difficulty and maintenance cost, and overall improving the convenience and safety of drill pipe use.

[0014] Preferably, the moving shaft assembly includes a moving shaft movably inserted into the first drill pipe, and a first moving seat connected to the end of the moving shaft.

[0015] The first clamping link assembly includes a first guide seat disposed inside the first drill pipe and fixedly connected to the first drill pipe, a first clamping assembly hinged to the first guide seat, and a first push-pull rod hinged to the first moving seat and the first clamping assembly respectively;

[0016] When the connecting shaft rod is inserted into the connecting shaft sleeve and presses against the first moving seat, the moving shaft moves in the direction of inserting into the first drill pipe. The first moving seat drives the first push-pull rod to move, so that the first push-pull rod pulls the first clamping assembly to move towards the second drill pipe and clamp the second drill pipe.

[0017] By adopting the above technical solutions, the direct pressing drive of the connecting shaft rod and the first moving seat simplifies the operation, and the hinged cooperation of the first moving seat, the first clamping assembly and the first push-pull rod ensures the accuracy and reliability of clamping; when the connecting shaft rod presses against the first moving seat, the first push-pull rod quickly pulls the first clamping assembly, realizing the tight clamping of the first clamping assembly on the second drill pipe; this design saves space, maintains the drill pipe structure compact, improves the operation efficiency, and enhances the construction safety.

[0018] Preferably, the second clamping link assembly includes a second guide seat disposed inside the second drill pipe and fixedly connected to the second drill pipe, a second clamping assembly hinged to the second guide seat, and a second push-pull rod hinged to the moving shaft sleeve assembly and the second clamping assembly respectively;

[0019] When the magnetic attraction assembly makes the ends of the connecting shaft sleeve and the moving shaft sleeve assembly closely adhere and adsorb to each other, and the connecting shaft sleeve and the moving shaft sleeve assembly move away from each other, the connecting shaft sleeve pulls the moving shaft sleeve assembly to move. The moving shaft sleeve assembly drives the second push-pull rod to move, so that the second push-pull rod pulls the second clamping assembly to move towards the first drill pipe and clamp the first drill pipe.

[0020] By adopting the above technical solutions, the design of the second clamping link assembly realizes the quick-response clamping of the first drill pipe. The fixed connection between the second guide seat and the second drill pipe provides a stable guiding basis. The second clamping assembly realizes a flexible flipping clamping action through the hinge with the second guide seat; the magnetic attraction assembly not only enables the ends of the connecting shaft sleeve and the moving shaft sleeve assembly to closely adsorb, but also when the connecting shaft sleeve and the moving shaft sleeve assembly move away from each other, through the pulling action of the connecting shaft sleeve, the moving shaft sleeve assembly drives the second push-pull rod to move, and then the second push-pull rod effectively pulls the second clamping assembly, realizing the quick clamping of the first drill pipe and maintaining the clamping trend; the simplification and automation of this clamping process significantly improve the efficiency and reliability of drill pipe connection, and at the same time avoid the possible damage problems in the thread connection method, enhancing the stability and durability of drill pipe connection.

[0021] Preferably, the connecting bushing is provided with bushing grooves arranged in an array along the circumferential direction, and the connecting shaft rod is provided with insertion grooves arranged in an array along the circumferential direction;

[0022] The second clamping link assembly includes a second clamping assembly. Both the first clamping assembly and the second clamping assembly include a first clamping rod, a second clamping rod connected to the first clamping rod, and an insertion limiting convex edge provided at the connection position between the first clamping rod and the second clamping rod; the insertion limiting convex edge is used to pass through the bushing groove and insert into the insertion groove to limit the relative rotation of the connecting bushing and the connecting shaft rod in the circumferential direction.

[0023] By adopting the above technical solution, the bushing grooves on the connecting bushing and the insertion grooves on the connecting shaft rod are both arranged in an array along the circumferential direction, forming a plurality of corresponding positioning points, increasing the flexibility and adaptability of the connection; by passing the insertion limiting convex edge provided at the connection position between the first clamping rod and the second clamping rod through the bushing groove and inserting it into the insertion groove, the relative circumferential rotation of the connecting bushing and the connecting shaft rod is effectively limited; this application not only enhances the anti-rotation ability between the first drill pipe and the second drill pipe, but also provides a more reliable connection guarantee by restricting rotation.

[0024] Preferably, fixing grooves are provided on the side walls of both the first drill pipe and the second drill pipe, and the end of the second clamping rod is provided with an insertion head for vertically inserting into the fixing groove.

[0025] By adopting the above technical solution, the insertion head can be vertically inserted into these fixing grooves; the fixing grooves provide clear guidance and stable positioning points for the second clamping rod, ensuring that the second clamping rod can be accurately inserted and hooked on the side wall of the first drill pipe or the second drill pipe; moreover, the insertion head vertically inserted into the fixing groove simplifies the disassembly and assembly process of the first drill pipe and the second drill pipe, improves the disassembly and assembly efficiency, enhances the connection stability between the first drill pipe and the second drill pipe, reduces the risk of loosening or falling off during construction, and improves the safety and durability of the drill pipe structure.

[0026] Preferably, insertion and fixing holes are provided on both the first drill pipe and the second drill pipe along the radial direction;

[0027] Both the first connection mechanism and the second connection mechanism include a connection fixing rod movably inserted into the insertion and fixing hole, a pressing convex edge provided at the end of the connection fixing rod, a handle provided at the end of the connection fixing rod, and limiting convex edges provided on both sides of the opening end of the insertion and fixing hole. There is a clearance groove for the pressing convex edge to insert between the two limiting convex edges, and there is a rotational clearance between the limiting convex edges and the first drill pipe and the second drill pipe respectively;

[0028] When the connecting and fixing rod is inserted into the plugging and fixing hole, the pressing convex edge is inserted from the clearance groove and moves into the rotation clearance space, and the connecting and fixing rod is rotated so that the outer side wall of the pressing convex edge is in pressing fit with the inner side wall of the limiting convex edge; the connecting and fixing rod is used to be inserted into the moving shaft and the moving shaft sleeve assembly respectively.

[0029] By adopting the above technical solution, the connecting and fixing rod is movably inserted into the plugging and fixing hole, the pressing convex edge is inserted from the clearance groove and moves into the rotation clearance space, and the connecting and fixing rod is rotated so that the outer side wall of the pressing convex edge is in pressing fit with the inner side wall of the limiting convex edge, which restricts the relative movement between the connecting and fixing rod and the first drill rod or the second drill rod respectively in the radial direction and enhances the connection stability; the connecting and fixing rod is used to be inserted into the moving shaft and the moving shaft sleeve assembly respectively to limit the relative movement between the moving shaft and the first drill rod and between the second drill rod and the moving shaft sleeve assembly; it is convenient to realize quick disassembly and assembly, improves the safety of the whole drill rod connection system and the convenience of operation; it prevents the first clamping mechanism and the second clamping mechanism from loosening due to the resistance of obstacles such as soil, sand and gravel during the up and down movement of the first drill rod and the second drill rod.

[0030] Preferably, the first clamping assembly and the second clamping assembly are arranged in a mutually crossed and closely attached manner.

[0031] By adopting the above technical solution, the first clamping assembly and the second clamping assembly are arranged in a mutually crossed and closely attached manner, which improves the stability of the first clamping mechanism and the second clamping mechanism and the uniformity of the distribution of the clamping force; this configuration enables the first clamping assembly and the second clamping assembly to act on the drill rod more effectively together, enhances the clamping effect, and at the same time, the crossed design helps to reduce the space occupation and optimize the spatial layout of the first clamping mechanism and the second clamping mechanism; the closely attached arrangement of the first clamping assembly and the second clamping assembly helps to increase the contact friction area between the first clamping mechanism and the second clamping mechanism, further improves the reliability of clamping, and ensures the firm connection and good performance of the drill rod during construction.

[0032] Preferably, the first clamping rod and the second clamping rod are arranged at an inclined angle to form an upper inclined slope surface and a lower inclined slope surface.

[0033] By adopting the above technical solution, the design of the upper inclined slope surface and the lower inclined slope surface helps to reduce the resistance during the up and down movement of the first drill rod and the second drill rod, and when being resisted by obstacles such as soil, sand and gravel, it will squeeze the upper inclined slope surface and the lower inclined slope surface, further improving the clamping effect of the first clamping mechanism and the second clamping mechanism.

[0034] A quick disassembly and assembly method for a quick disassembly and assembly drill rod of a reverse-lifting drill rig further includes the following steps:

[0035] S1: Install the first drill pipe and the second drill pipe: Insert the connecting shaft rod into the connecting shaft sleeve;

[0036] S2: The connecting shaft rod presses against the moving shaft assembly, and the moving shaft assembly drives the first clamping link assembly to flip and clamp the second drill pipe;

[0037] S3: The first connecting mechanism is inserted into the first drill pipe and connects and fixes the moving shaft assembly and the first drill pipe;

[0038] S4: Push the second clamping link assembly to clamp the first drill pipe, and the magnetic attraction assembly makes the ends of the connecting shaft sleeve and the moving shaft sleeve assembly closely adhere to and attract each other;

[0039] S5: The second connecting mechanism is inserted into the second drill pipe and connects and fixes the moving shaft sleeve assembly and the second drill pipe;

[0040] S6: Disassemble the first drill pipe and the second drill pipe: Pull out the first connecting mechanism and the second connecting mechanism respectively;

[0041] S7: Pull the second clamping link assembly to move away from the first drill pipe, and separate the ends of the connecting shaft sleeve and the moving shaft sleeve assembly;

[0042] S8: Pull the first clamping link assembly to move away from the second drill pipe, and synchronously pull the first drill pipe and the second drill pipe to separate from each other.

[0043] By adopting the above technical solutions, in step S2, the connecting shaft rod presses against the moving shaft assembly to realize the flipping and clamping of the first clamping link assembly, providing stability for the second drill pipe; in step S3, the insertion and fixation of the first connecting mechanism enhance the connection strength between the moving shaft assembly and the first drill pipe and limit the relative movement between the moving shaft assembly and the first drill pipe; in step S4, through the clamping of the second clamping link assembly and the adsorption of the magnetic attraction assembly, the tight fit between the connecting shaft sleeve and the moving shaft sleeve assembly is ensured; in step S5, further through the insertion and fixation of the second connecting mechanism, the connection between the moving shaft sleeve assembly and the second drill pipe is strengthened and the relative movement between the moving shaft sleeve assembly and the second drill pipe is limited; the disassembly process in step S6 simplifies the operation by pulling out the first connecting mechanism and the second connecting mechanism; the coordinated actions in steps S7 and S8 achieve the rapid separation of the first drill pipe and the second drill pipe; the entire process simplifies the disassembly and assembly procedures, reduces the dependence on tools, improves the operation efficiency and safety, and at the same time ensures the reliability of the drill pipe connection.

[0044] Preferably, in step S3, the first connecting mechanism is inserted into the first drill pipe along the radial direction of the first drill pipe, and in step S5, the second connecting mechanism is inserted into the second drill pipe along the radial direction of the second drill pipe.

[0045] By adopting the above technical solution, the first connecting mechanism and the second connecting mechanism are inserted along the radial directions of the first drill pipe and the second drill pipe respectively, which simplifies the installation process of the first connecting mechanism and the second connecting mechanism, makes the operation more direct and convenient, and enhances the stability of the overall structure; moreover, the design of radial insertion also helps to reduce the occupation of the external space of the drill pipe by the first connecting mechanism and the second connecting mechanism, makes the layout of the drill pipe more compact, and optimizes the space utilization; this connection method is convenient for quick disassembly and assembly, improves the flexibility of drill pipe use and the convenience of maintenance.

[0063] The following further describes the present application in detail Figures 1-6 in conjunction with the accompanying drawings.

[0064] An embodiment of the present application discloses a quickly detachable drill pipe for a reverse-lifting drilling rig. Referring to Figure 1 , the quickly detachable drill pipe includes a first drill pipe 1, a second drill pipe 2 axially arranged corresponding to the first drill pipe 1, a first clamping mechanism 3 connected to the end of the first drill pipe 1 and used for clamping the end of the second drill pipe 2, a second clamping mechanism 4 connected to the end of the second drill pipe 2 and used for clamping the end of the first drill pipe 1, a first connection mechanism 5 inserted into the first drill pipe 1 in the radial direction and used for connecting the first drill pipe 1 and the first clamping mechanism 3, and a second connection mechanism 6 inserted into the second drill pipe 2 in the radial direction and used for connecting the second drill pipe 2 and the second clamping mechanism 4;

[0065] A connection sleeve 7 is provided at the end of the first drill pipe 1, and a connection shaft rod 8 for inserting into the connection sleeve 7 is provided at the end of the second drill pipe 2;

[0066] The first clamping mechanism 3 includes a moving shaft assembly 31 movably inserted into the interior of the first drill pipe 1, and a first clamping link assembly 32 hinged to the moving shaft assembly 31; the second clamping mechanism 4 includes a moving shaft sleeve assembly 41 movably inserted into the interior of the second drill pipe 2, a second clamping link assembly 42 hinged to the moving shaft sleeve assembly 41, and a magnetic attraction assembly 43 respectively disposed on the connecting shaft sleeve 7 and the moving shaft sleeve assembly 41, and the magnetic attraction assembly 43 is used for the ends of the connecting shaft sleeve 7 and the moving shaft sleeve assembly 41 to be tightly attached and adsorbed to each other;

[0067] When the connecting shaft rod 8 is inserted into the connecting shaft sleeve 7, the connecting shaft rod 8 presses against the moving shaft assembly 31, and the moving shaft assembly 31 drives the first clamping link assembly 32 to flip and clamp the second drill pipe 2;

[0068] When the connecting shaft rod 8 is withdrawn from the connecting shaft sleeve 7, the connecting shaft sleeve 7 adsorbs and pulls the moving shaft sleeve assembly 41, and the moving shaft sleeve assembly 41 drives the second clamping link assembly 42 to flip and clamp the first drill pipe 1.

[0069] In this application, when the connecting shaft rod 8 is inserted into the connecting shaft sleeve 7, the connecting shaft rod 8 presses against the moving shaft assembly 31, and the moving shaft assembly 31 drives the first clamping link assembly 32 to flip and clamp the second drill pipe 2, and the first connecting mechanism 5 connects the first drill pipe 1 and the moving shaft assembly 31; when the first drill pipe 1 pushes the second drill pipe 2 to move downward, the connecting shaft rod 8 and the moving shaft assembly 31 maintain a mutually pressing trend, thereby enabling the first clamping link assembly 32 to maintain a trend of clamping the second drill pipe 2;

[0070] When the second clamping link assembly 42 clamps the first drill pipe 1, the second connecting mechanism 6 connects and fixes the second drill pipe 2 and the moving shaft sleeve assembly 41; when the first drill pipe 1 and the second drill pipe 2 move upward, the connecting shaft sleeve 7 adsorbs and maintains a trend of pulling the moving shaft sleeve assembly 41, and the moving shaft sleeve assembly 41 drives the second clamping link assembly 42 to flip and maintain a trend of clamping the first drill pipe 1;

[0071] So that when the first drill pipe 1 and the second drill pipe 2 move up and down, they can maintain a tight connection and are not easily separated, and when it is necessary to separate the first drill pipe 1 and the second drill pipe 2, directly disassemble the first connecting mechanism 5 and the second connecting mechanism 6, pull the first clamping link assembly 32 away from the second drill pipe 2, pull the second clamping link assembly 42 away from the first drill pipe 1, and synchronously separate the first drill pipe 1 and the second drill pipe 2; this application realizes fast and stable clamping and release between drill pipes through the first clamping mechanism 3 and the second clamping mechanism 4, avoiding the problem of thread damage. The clamping and release operations between the first drill pipe 1 and the second drill pipe 2 in this application are simple and do not require tool assistance, greatly reducing the operation difficulty and maintenance cost, and overall improving the convenience and safety of drill pipe use.

[0072] Further, as Figure 2As shown, the moving shaft assembly 31 includes a moving shaft 311 movably inserted into the first drill pipe 1, and a first moving seat 312 connected to the end of the moving shaft 311;

[0073] The first clamping link assembly 32 includes a first guide seat 321 disposed inside the first drill pipe 1 and fixedly connected to the first drill pipe 1, a first clamping assembly 322 hinged to the first guide seat 321, and a first push-pull rod 323 respectively hinged to the first moving seat 312 and the first clamping assembly 322;

[0074] When the connecting shaft rod 8 is inserted into the connecting shaft sleeve 7 and presses against the first moving seat 312, the moving shaft 311 moves in the direction of inserting into the first drill pipe 1. The first moving seat 312 drives the first push-pull rod 323 to move, so that the first push-pull rod 323 pulls the first clamping assembly 322 to move towards the second drill pipe 2 and clamp the second drill pipe 2.

[0075] In this application, efficient clamping is achieved through the coordinated action of the moving shaft assembly 31 and the first clamping link assembly 32; the direct pressing drive of the connecting shaft rod 8 and the first moving seat 312 simplifies the operation, while the hinged cooperation of the first moving seat 312, the first clamping assembly 322 and the first push-pull rod 323 ensures the accuracy and reliability of clamping; when the connecting shaft rod 8 presses against the first moving seat 312, the first push-pull rod 323 quickly pulls the first clamping assembly 322, realizing the tight clamping of the first clamping assembly 322 on the second drill pipe 2; this design saves space, maintains the drill pipe structure in a compact form, improves the operation efficiency, and enhances the construction safety.

[0076] Furthermore, as Figure 3 shown, the second clamping link assembly 42 includes a second guide seat 421 disposed inside the second drill pipe 2 and fixedly connected to the second drill pipe 2, a second clamping assembly 422 hinged to the second guide seat 421, and a second push-pull rod 423 respectively hinged to the moving shaft sleeve assembly 41 and the second clamping assembly 422;

[0077] When the magnetic attraction assembly 43 makes the ends of the connecting shaft sleeve 7 and the moving shaft sleeve assembly 41 tightly adhere and adsorb to each other, and the connecting shaft sleeve 7 and the moving shaft sleeve assembly 41 move away from each other, the connecting shaft sleeve 7 pulls the moving shaft sleeve assembly 41 to move. The moving shaft sleeve assembly 41 drives the second push-pull rod 423 to move, so that the second push-pull rod 423 pulls the second clamping assembly 422 to move towards the first drill pipe 1 and clamp the first drill pipe 1.

[0078] The design of the second clamping link assembly 42 of this application realizes the quick-response clamping of the first drill pipe 1. The fixed connection between the second guide seat 421 and the second drill pipe 2 provides a stable guiding foundation. The second clamping assembly 422 realizes a flexible flipping clamping action through the hinge connection with the second guide seat 421; the magnetic attraction assembly 43 not only enables the end of the connecting bushing 7 and the moving bushing assembly 41 to be tightly adsorbed, but also when the connecting bushing 7 and the moving bushing assembly 41 move away from each other, through the pulling action of the connecting bushing 7, the moving bushing assembly 41 drives the second push rod 423 to move, and further enables the second push rod 423 to effectively pull the second clamping assembly 422, realizing the quick clamping of the first drill pipe 1 and maintaining the clamping tendency; the simplification and automation of this clamping process significantly improve the efficiency and reliability of drill pipe connection, and at the same time avoid the possible damage problems in the thread connection method, enhancing the stability and durability of drill pipe connection. The magnetic attraction assembly 43 is preferably a magnet or an electromagnet.

[0079] Specifically, as Figure 2 and Figure 4 shown, the connecting bushing 7 is provided with bushing grooves 71 arranged in an array along the circumferential direction, and the connecting shaft rod 8 is provided with insertion grooves 81 arranged in an array along the circumferential direction;

[0080] The second clamping link assembly 42 includes a second clamping assembly 422. Both the first clamping assembly 322 and the second clamping assembly 422 include a first clamping rod 3221, a second clamping rod 3222 connected to the first clamping rod 3221, and an insertion limiting convex edge 3223 arranged at the connection position of the first clamping rod 3221 and the second clamping rod 3222; the insertion limiting convex edge 3223 is used to pass through the bushing groove 71 and insert into the insertion groove 81 to limit the relative rotation of the connecting bushing 7 and the connecting shaft rod 8 in the circumferential direction.

[0081] The bushing grooves 71 on the connecting bushing 7 and the insertion grooves 81 on the connecting shaft rod 8 of this application are both arranged in an array along the circumferential direction, forming a plurality of corresponding positioning points, increasing the flexibility and adaptability of the connection; by passing the insertion limiting convex edge 3223 arranged at the connection position of the first clamping rod 3221 and the second clamping rod 3222 through the bushing groove 71 and inserting it into the insertion groove 81, the relative circumferential rotation of the connecting bushing 7 and the connecting shaft rod 8 is effectively restricted; this application not only enhances the anti-rotation ability between the first drill pipe 1 and the second drill pipe 2, but also provides a more reliable connection guarantee by restricting the rotation, while simplifying the docking and fixing process of the first drill pipe 1 and the second drill pipe 2, improving the efficiency of quick disassembly and assembly and the stability of the overall structure.

[0082] More specifically, as Figure 2 and Figure 4As shown, fixing grooves 11 are provided on the side walls of the first drill pipe 1 and the second drill pipe 2, and the end of the second clamping rod 3222 is provided with a plug joint 3224 for vertically inserting into the fixing groove 11.

[0083] In this application, fixing grooves 11 are designed on the side walls of both the first drill pipe 1 and the second drill pipe 2, and the plug joint 3224 provided at the end of the second clamping rod 3222 can vertically insert into these fixing grooves 11; the fixing grooves 11 provide a clear guide and a stable positioning point for the second clamping rod 3222, ensuring that the second clamping rod 3222 can accurately insert and hook the side wall of the first drill pipe 1 or the second drill pipe 2; moreover, the plug joint 3224 vertically inserted into the fixing groove 11 simplifies the disassembly and assembly process of the first drill pipe 1 and the second drill pipe 2, improves the disassembly and assembly efficiency, enhances the stability of the connection between the first drill pipe 1 and the second drill pipe 2, reduces the risk of loosening or falling off during construction, and improves the safety and durability of the drill pipe structure.

[0084] In addition, as Figure 2 and Figure 5 shown, plugging and fixing holes 12 are provided on the first drill pipe 1 and the second drill pipe 2 along the radial direction;

[0085] Both the first connecting mechanism 5 and the second connecting mechanism 6 include a connecting and fixing rod 51 movably inserted into the plugging and fixing hole 12, a pressing flange 52 provided at the end of the connecting and fixing rod 51, a handle 53 provided at the end of the connecting and fixing rod 51, and limiting flanges 54 provided on both sides of the opening end of the plugging and fixing hole 12. A clearance groove 55 for the pressing flange 52 to insert is provided between the two limiting flanges 54, and a rotational clearance 56 is provided between the limiting flanges 54 and the first drill pipe 1 and the second drill pipe 2 respectively;

[0086] When the connecting and fixing rod 51 is inserted into the plugging and fixing hole 12, the pressing flange 52 inserts from the clearance groove 55 and moves into the rotational clearance 56, and the connecting and fixing rod 51 is rotated so that the outer side wall of the pressing flange 52 is in pressing fit with the inner side wall of the limiting flange 54; the connecting and fixing rod 51 is used to insert into the moving shaft 311 and the moving shaft sleeve assembly 41 respectively.

[0087] The first drill pipe 1 and the second drill pipe 2 of the present application are both provided with insertion fixing holes 12 in the radial direction. The first connection mechanism 5 and the second connection mechanism 6 are respectively designed for insertion and cooperation with the insertion fixing holes 12, providing a simple and efficient connection and fixing method. The connection fixing rod 51 is movably inserted into the insertion fixing hole 12, and the pressing convex edge 52 is inserted from the clearance groove 55 and moved into the rotation clearance gap 56. The connection fixing rod 51 is rotated so that the outer side wall of the pressing convex edge 52 is in pressing cooperation with the inner side wall of the limiting convex edge 54, restricting the relative movement between the connection fixing rod 51 and the first drill pipe 1 or the second drill pipe 2 in the radial direction and enhancing the stability of the connection. The connection fixing rod 51 is used to be respectively inserted into the moving shaft 311 and the moving shaft sleeve assembly 41 to restrict the relative movement between the moving shaft 311 and the first drill pipe 1 and between the second drill pipe 2 and the moving shaft sleeve assembly 41. It is convenient to realize quick disassembly and assembly, improving the safety of the entire drill pipe connection system and the convenience of operation. It prevents the first clamping mechanism 3 and the second clamping mechanism 4 from loosening due to the resistance of obstacles such as soil and sand during the up and down movement of the first drill pipe 1 and the second drill pipe 2.

[0088] And, as Figure 2 and 3 shown, the first clamping component 322 and the second clamping component 422 intersect and are tightly attached to each other.

[0089] Through the intersecting and tightly attached arrangement of the first clamping component 322 and the second clamping component 422 of the present application, the stability of the first clamping mechanism 3 and the second clamping mechanism 4 and the uniformity of the distribution of the clamping force are improved. This configuration enables the first clamping component 322 and the second clamping component 422 to act on the drill pipe more effectively together, enhancing the clamping effect. At the same time, the cross design helps to reduce the space occupation and optimize the spatial layout of the first clamping mechanism 3 and the second clamping mechanism 4. The tightly attached arrangement of the first clamping component 322 and the second clamping component 422 helps to increase the contact friction area between the first clamping mechanism 3 and the second clamping mechanism 4, further improving the reliability of clamping and ensuring the firm connection and good performance of the drill pipe during construction.

[0090] Furthermore, as Figure 2 shown, the first clamping rod 3221 and the second clamping rod 3222 are arranged at an inclined angle to form an upper inclined slope 9 and a lower inclined slope 10.

[0091] In the present application, the first clamping rod 3221 and the second clamping rod 3222 are arranged at an inclined angle, forming an upper inclined slope 9 and a lower inclined slope 10; the design of the upper inclined slope 9 and the lower inclined slope 10 helps to reduce the resistance during the up and down movement of the first drill pipe 1 and the second drill pipe 2, and when encountering resistance from obstacles such as soil, sand and gravel, it will squeeze the upper inclined slope 9 and the lower inclined slope 10, further improving the clamping effect of the first clamping mechanism 3 and the second clamping mechanism 4.

[0092] Furthermore, as Figure 6 shown, the present application also discloses a quick disassembly and assembly method for quickly disassembling and assembling drill pipes of a reverse lifting drill rig, which further includes the following steps:

[0093] S1: Install the first drill pipe 1 and the second drill pipe 2: Insert the connecting shaft rod 8 into the connecting shaft sleeve 7;

[0094] S2: The connecting shaft rod 8 presses against and moves the moving shaft assembly 31, and the moving shaft assembly 31 drives the first clamping link assembly 32 to flip and clamp the second drill pipe 2;

[0095] S3: The first connecting mechanism 5 is inserted into the first drill pipe 1 and connects and fixes the moving shaft assembly 31 and the first drill pipe 1;

[0096] S4: Push the second clamping link assembly 42 to clamp the first drill pipe 1, and the magnetic attraction assembly 43 makes the end parts of the connecting shaft sleeve 7 and the moving shaft sleeve assembly 41 closely adhere and adsorb to each other;

[0097] S5: The second connecting mechanism 6 is inserted into the second drill pipe 2 and connects and fixes the moving shaft sleeve assembly 41 and the second drill pipe 2;

[0098] S6: Disassemble the first drill pipe 1 and the second drill pipe 2: Pull out the first connecting mechanism 5 and the second connecting mechanism 6 respectively;

[0099] S7: Pull the second clamping link assembly 42 to move in a direction away from the first drill pipe 1, and separate the end parts of the connecting shaft sleeve 7 and the moving shaft sleeve assembly 41;

[0100] S8: Pull the first clamping link assembly 32 to move in a direction away from the second drill pipe 2, and synchronously pull the first drill pipe 1 and the second drill pipe 2 to separate from each other.

[0101] In step S1 of this application, preliminary docking is achieved by inserting the connecting shaft rod 8 into the connecting shaft sleeve 7; in step S2, the connecting shaft rod 8 is used to press against the moving shaft assembly 31 to achieve the flipping and clamping of the first clamping link assembly 32, providing stability for the second drill pipe 2; in step S3, the insertion and fixation of the first connecting mechanism 5 enhance the connection strength between the moving shaft assembly 31 and the first drill pipe 1 and limit the relative movement between the moving shaft assembly 31 and the first drill pipe 1; in step S4, through the clamping of the second clamping link assembly 42 and the adsorption of the magnetic adsorption assembly 43, the tight fit between the connecting shaft sleeve 7 and the moving shaft sleeve assembly 41 is ensured; in step S5, further through the insertion and fixation of the second connecting mechanism 6, the connection between the moving shaft sleeve assembly 41 and the second drill pipe 2 is strengthened, and the relative movement between the moving shaft sleeve assembly 41 and the second drill pipe 2 is limited; the disassembly process in step S6 simplifies the operation by pulling out the first connecting mechanism 5 and the second connecting mechanism 6; the coordinated actions in steps S7 and S8 achieve the rapid separation of the first drill pipe 1 and the second drill pipe 2; the entire process simplifies the disassembly and assembly procedures, reduces the dependence on tools, improves the operation efficiency and safety, and at the same time ensures the reliability of the drill pipe connection.

[0102] Specifically, in step S3, the first connecting mechanism 5 is inserted into the first drill pipe 1 along the radial direction of the first drill pipe 1, and in step S5, the second connecting mechanism 6 is inserted into the second drill pipe 2 along the radial direction of the second drill pipe 2.

[0103] In this application, by inserting the first connecting mechanism 5 and the second connecting mechanism 6 along the radial directions of the first drill pipe 1 and the second drill pipe 2 respectively, the installation process of the first connecting mechanism 5 and the second connecting mechanism 6 is simplified, making the operation more direct and convenient, and enhancing the stability of the overall structure; moreover, the radial insertion design helps to reduce the occupation of the external space of the drill pipe by the first connecting mechanism 5 and the second connecting mechanism 6, making the drill pipe layout more compact and optimizing the space utilization; this connection method facilitates rapid disassembly and assembly, improving the flexibility of drill pipe use and the convenience of maintenance.

[0104] The implementation principle of an embodiment of a quick-disassembly drill pipe for a reverse-lifting drill rig and a method for quickly disassembling and assembling the drill pipe in this application is as follows:

[0105] A quick-disassembly drill pipe for a reverse-lifting drill rig, with a connecting shaft rod 8 inserted into a connecting shaft sleeve 7, the connecting shaft rod 8 pressing against a moving shaft assembly 31, the moving shaft assembly 31 driving a first clamping link assembly 32 to flip and clamp the second drill pipe 2, and a first connecting mechanism 5 connecting the first drill pipe 1 and the moving shaft assembly 31; when the first drill pipe 1 pushes the second drill pipe 2 downward, the connecting shaft rod 8 and the moving shaft assembly 31 maintain a mutually pressing trend, thereby causing the first clamping link assembly 32 to maintain a trend of clamping the second drill pipe 2.

[0106] When the second clamping link assembly 42 clamps the first drill pipe 1, the second connection mechanism 6 connects and fixes the second drill pipe 2 and the moving bushing assembly 41; when the first drill pipe 1 and the second drill pipe 2 move upward, the connecting bushing 7 adsorbs and maintains the tendency to pull the moving bushing assembly 41, and the moving bushing assembly 41 drives the second clamping link assembly 42 to flip and maintain the tendency to clamp the first drill pipe 1;

[0107] So that when the first drill pipe 1 and the second drill pipe 2 move up and down, they can be kept tightly connected and not easily separated. And when it is necessary to separate the first drill pipe 1 and the second drill pipe 2, directly disassemble the first connection mechanism 5 and the second connection mechanism 6, pull the first clamping link assembly 32 away from the second drill pipe 2, pull the second clamping link assembly 42 away from the first drill pipe 1, and synchronously separate the first drill pipe 1 and the second drill pipe 2; The present application realizes the fast and stable clamping and release between drill pipes through the first clamping mechanism 3 and the second clamping mechanism 4, avoiding the problem of thread damage. The clamping and release operations between the first drill pipe 1 and the second drill pipe 2 of the present application are simple and do not require tool assistance, greatly reducing the operation difficulty and maintenance cost, and overall improving the convenience and safety of drill pipe use;

[0108] The bushing grooves 71 on the connecting bushing 7 and the insertion grooves 81 on the connecting shaft rod 8 are both arranged in a circumferential array, forming a plurality of corresponding positioning points, increasing the flexibility and adaptability of the connection; by passing the insertion limit convex edge 3223 provided at the connection position of the first clamping rod 3221 and the second clamping rod 3222 through the bushing groove 71 and inserting it into the insertion groove 81, the circumferential relative rotation between the connecting bushing 7 and the connecting shaft rod 8 is effectively restricted; The present application not only enhances the anti-rotation ability between the first drill pipe 1 and the second drill pipe 2, but also provides a more reliable connection guarantee by restricting the rotation. At the same time, it simplifies the docking and fixing process of the first drill pipe 1 and the second drill pipe 2, improving the efficiency of quick disassembly and assembly and the stability of the overall structure;

[0109] A quick disassembly and assembly method for quickly disassembling and assembling drill pipes of a reverse-lifting drilling rig. In step S1, preliminary docking is achieved by inserting a connecting shaft rod 8 into a connecting shaft sleeve 7. In step S2, the connecting shaft rod 8 is used to press against and move the shaft assembly 31, realizing the flipping and clamping of the first clamping link assembly 32 to provide stability for the second drill pipe 2. In step S3, the insertion and fixation of the first connecting mechanism 5 enhance the connection strength between the moving shaft assembly 31 and the first drill pipe 1 and limit the relative movement between the moving shaft assembly 31 and the first drill pipe 1. In step S4, through the clamping of the second clamping link assembly 42 and the adsorption effect of the magnetic adsorption assembly 43, the tight fit between the connecting shaft sleeve 7 and the moving shaft sleeve assembly 41 is ensured. In step S5, further through the insertion and fixation of the second connecting mechanism 6, the connection between the moving shaft sleeve assembly 41 and the second drill pipe 2 is strengthened, and the relative movement between the moving shaft sleeve assembly 41 and the second drill pipe 2 is limited. The disassembly process in step S6 simplifies the operation by pulling out the first connecting mechanism 5 and the second connecting mechanism 6. The coordinated actions in steps S7 and S8 achieve the quick separation of the first drill pipe 1 and the second drill pipe 2. The entire process simplifies the disassembly and assembly procedures, reduces the dependence on tools, improves the operation efficiency and safety, and at the same time ensures the reliability of the drill pipe connection.

Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
