Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a drill pipe system and its usage method. Background Technology

[0002] Rotary drilling rigs are widely used engineering machines, primarily for drilling in soil, gravel, soft rock, and other geological conditions. Their development can be traced back to the accelerated pace of urbanization and the increasing demand for infrastructure construction, particularly in bridges, tunnels, subways, and high-rise buildings. Traditional rotary drilling equipment struggles in low-headroom operations such as tunnels, underground engineering projects, and factory buildings, leading to the emergence of low-headroom rotary drilling rigs. These rigs are specifically designed for confined spaces and specific environments, enabling them to flexibly and efficiently address construction challenges.

[0003] Currently, in construction within confined spaces, the height of rotary drilling rigs is limited, necessitating control over the drill rod structure to achieve a certain drilling depth. To ensure that a novel drill rod device meets drilling depth requirements and can be fully automated, saving manpower and time, this invention designs a drill rod system and its usage method. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a drill rod system and its usage method, which can achieve full automation, saving significant manpower and resources. Furthermore, it enables precise detection of the drill rod surface cleanliness and faster, more convenient extraction of loess generated during drilling, achieving simultaneous drilling and soil removal.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A drill pipe system includes an intelligent lifting clamp, a vision sorting system, an electrically controlled clamping and rotating mechanism, and a multi-section threaded block cutting drill pipe mechanism: the intelligent lifting clamp is connected to the vehicle body floor plate by welding and controls the fixing and lifting of the drill pipe;

[0007] The vision sorting system is installed on the intelligent lifting fixture and uses machine vision to identify and remove foreign objects from the surface of the drill pipe.

[0008] The electrically controlled clamping and rotating mechanism is fixed on the bracket and drives the drill rod to rotate, thereby realizing automated rod disassembly.

[0009] The multi-section threaded block cutting drill rod mechanism is installed on the electrically controlled clamping and rotating mechanism and is used to cut large soil clods that appear in the loess and prevent the drill rod from becoming blocked.

[0010] As a further embodiment of the present invention: the intelligent lifting fixture includes a fixed plate, a ball screw lifting platform, an electric push rod, an electric push rod support frame, a rigid connecting key, and mechanical scissors. The ball screw lifting platform is fixedly installed on the fixed plate, the electric push rod support frame is provided on the ball screw lifting platform, the electric push rod is vertically installed on the electric push rod support frame, the electric push rod is provided with a rigid connecting key, and the mechanical scissors are movably connected to the rigid connecting key.

[0011] As a further aspect of the present invention: the visual sorting system includes a CMOS camera, OpenCV image processing software, an alarm system, and a PLC control system. The CMOS camera acquires images, and the OpenCV image processing software performs precise image processing. An alarm system is set with a particle size and volume threshold. Once the particle size and volume are exceeded, an alarm will be triggered. The PLC control system uses feedback information to perform intelligent lifting and clamping adjustments, as well as subsequent drill rod surface cleaning.

[0012] As a further aspect of the present invention: the electrically controlled clamping and rotating mechanism includes a DC motor, a small gear, a large gear, an outer ring, a rotating ring, a flat key block, and a rotating clamping block. The DC motor is connected to the small gear via a key, thereby driving the large gear to rotate counterclockwise. The rotating clamping block is driven by the flat key block to rotate inward, thereby forming a clamp. Under the action of the clamping force, the drill rod is driven to rotate, ultimately achieving automated rod connection and disconnection.

[0013] As a further aspect of the present invention: the multi-section threaded block-cutting drill rod mechanism includes a drill rod, a rotary drill bit, a rigid shaft, soil-breaking blades, rolling bearings, an isolation ring, a gasket, and a filter screen; the drill rod is connected to a reducer, a rotary drill bit, or the next section of the drill rod via male and female threads as connectors; the rigid shaft, soil-breaking blades, rolling bearings, isolation ring, and gasket together form a soil-breaking device, which uses the wind power generated by a fan and a cyclone separator to provide power for the soil-breaking device, cutting and crushing large soil blocks that cannot be sucked out due to their weight and volume, and then filtering them through the filter screen before suction and discharge, effectively preventing the drill rod from clogging.

[0014] As a further aspect of the present invention: a cyclone separator is provided on one side of the intelligent lifting clamp, and a fan is provided on one side of the cyclone separator.

[0015] As a further aspect of the present invention: a method for using a drill rod system includes the following steps: clamping the drill rod with an intelligent lifting clamp, bringing the drill rod into contact with a reducer, and connecting the drill rod by controlling the reducer to rotate in the opposite direction; similarly, connecting the rotary drill bit to the drill rod; when connecting the second drill rod, the intelligent lifting clamp needs to be used to select a position to clamp the first section of the drill rod, at which time a vision sorting system needs to scan the surface of the drill rod to check for large particles embedded in the surface during the drilling process; once large foreign objects are detected, an alarm is triggered and feedback is sent to the control system for surface cleaning; then, the electrically controlled clamping and rotating mechanism is used to proceed... Clamp the upper end of the rotary drill bit and rotate it counterclockwise to separate the rotary drill bit from the first drill rod. After complete separation, insert the stud and stop the electrically controlled clamping mechanism from rotating, while maintaining the clamping posture. At the same time, connect the second drill rod and repeat the rod connection operation of the first drill rod. During drilling, the blower and cyclone separator suck the loess formed in the borehole from the hollow drill rod. The wind power generated by the blower and cyclone separator provides power for the soil crushing device, cutting and crushing large soil clods that cannot be sucked out due to their weight and volume. After being filtered through a filter screen, the soil is then sucked out, which effectively prevents the drill rod from clogging.

[0016] The beneficial effects of this invention are:

[0017] (1) The new drill pipe system and its usage method can automatically control the up and down movement of the drill pipe, and make precise and fast connections, thereby reducing manpower and time costs.

[0018] (2) The new drill rod system and its usage method can accurately detect burrs and foreign objects on the surface of the drill rod, ensure the smoothness of the drill rod surface, and prevent damage to the clamps and scratches to the human body.

[0019] (3) The new drill pipe system and its usage method can automatically perform pipe connection and replacement operations, saving a lot of manpower.

[0020] (4) The new drill rod system and its usage method can quickly cut large volume and heavy soil blocks to prevent soil blocks from accumulating inside the drill rod, causing the drill rod to become blocked and unable to be pumped out. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-7 As shown, this invention is a drill rod system, including an intelligent lifting clamp 1, a vision sorting system 2, an electrically controlled clamping and rotating mechanism 3, and a multi-section threaded block-cutting drill rod mechanism 4. The intelligent lifting clamp 1 is connected to the vehicle chassis by welding, controlling the fixing and lifting of the drill rod 41. The vision sorting system 2 uses machine vision to identify and remove foreign objects from the surface of the drill rod 41. The electrically controlled clamping and rotating mechanism 3 is fixed to a bracket and drives the drill rod 41 to rotate, achieving automated rod removal. The multi-section threaded block-cutting drill rod mechanism 4 connects the drill rods via threaded joints. A soil-breaking device is installed inside the drill rod 41 to cut and extract large soil clods from the loess, preventing blockage of the drill rod 41.

[0032] The intelligent lifting clamp 1 includes a fixed plate 11, a ball screw lifting platform 12, an electric push rod 13, an electric push rod support frame 14, rigid connecting keys 15, and mechanical shears 16. The fixed plate 11 is welded to the front end of the base plate, and bolts are used to bind the fixed plate 11 to the ball screw lifting platform 12. Simultaneously, the electric push rod support frame 14 is bolted to the worktable of the ball screw lifting platform 12, and the electric push rod 13 is bolted to the support frame. A pin connects the front end of the electric push rod 13 to two rigid connecting keys 15. Similarly, a pin connects one end of the rigid connecting key 15 to the two handle ends of the mechanical shears 16, which is composed of two steel plates crosswise. The up-and-down movement of the ball screw lifting platform 12 controls the clamp to hold the drill rod 41 at different positions and can drive the drill rod 41 to connect with the reducer 5, reducing working time. The electric push rod 13, through its telescopic action, retracts the mechanical shears 16 to form the clamp.

[0033] The visual sorting system 2 includes a CMOS camera 21, OpenCV image processing software, an alarm system, and a PLC control system. The CMOS camera 21 is placed on the ball screw lifting platform 12, equipped with multi-angle cameras to ensure comprehensive capture of the shape and size of the soil clods. Image preprocessing is performed using OpenCV software, including grayscale conversion, noise removal, and edge detection, to make the foreign object outline clearer. Region segmentation technology is used for background removal to separate the foreign object from the complex background. The Canny edge detection algorithm is used to obtain the foreign object outline, and the outline detection algorithm is used to obtain the shape and area of ​​the foreign object. The major and minor axes of the soil clod are calculated to determine whether its size meets the screening criteria. An alarm system with a threshold set according to the size of the foreign object is used. When a foreign object exceeding the threshold is detected, a signal is sent to the PLC control system for signal processing, which triggers a light alarm. Based on the feedback information, the intelligent lifting clamp 1 is adjusted, and the surface of the drill rod 41 is subsequently cleaned.

[0034] The electrically controlled clamping mechanism 3 includes a DC motor 31, a pinion 32, a large gear 33, an outer ring 34, a rotating ring 35, a flat key block 36, and a rotating locking block 37. The DC motor 31 is bolted to the lower support and directly connected to the pinion 32. The outer ring 34 is welded to the lower support. The rotating ring 35 is fitted inside the outer ring 34, and the large gear 33 is welded to the rotating ring 35. The rotating ring 35 has four circular through-holes 38 and four arc-shaped keyways 39. The four circular through-holes 38 are connected to one end of the flat key block 36 with headless screws, and the four arc-shaped keyways 39 are connected to the through-holes of the outer ring 34 with headless screws, ensuring that the rotating ring 35 maintains its clamping posture even after it stops working. The rotating locking block 37 is welded to one end of the flat key block 36, and one through-hole in the rotating locking block 37 is connected to the outer ring 34 with a headless screw. The DC motor 31 drives the small gear 32 to rotate, which in turn drives the large gear 33 to rotate through gear meshing. The large gear 33 drives the rotating ring 35 to rotate, which in turn drives the flat key block 36 to rotate, and then the rotating block 37 to rotate inward to form a clamping posture.

[0035] The multi-section threaded block drill rod mechanism 4 includes a drill rod 41, a rotary drill bit 42, a rigid shaft 43, soil-breaking blades 44, rolling bearings 45, isolation rings 46, gaskets 47, and a filter screen 48. The drill rod 41 is connected to the reducer 5, the rotary drill bit 42, or the next drill rod 41 via male and female threads. A through hole is drilled in the drill rod 41 for inserting the rigid shaft 43. The rolling bearings 45 are connected to the rigid shaft 43 via an interference fit. Gaskets 47 are placed between each rolling bearing 45, and isolation rings 46 are placed on both sides of the rolling bearings 45 at both ends to prevent them from shaking or shifting. The soil-breaking blades 44 are welded to the outer surface of the rolling bearings 45. The rigid shaft 43, soil-breaking blades 44, rolling bearings 45, isolation rings 46, and gaskets 47 together form a soil-breaking device. The soil-breaking device is connected to the rigid shaft 43 through the hole in the drill rod 41, and the two ends of the rigid shaft 43 are fixed by pins. The wind generated by the blower 7 and the cyclone separator 6 provides power to the soil crushing device, which cuts and crushes large soil clods that cannot be sucked out due to their weight and volume. After being filtered through the filter screen 48, the soil is sucked out, which effectively prevents the drill rod 41 from clogging and failing to discharge the soil.

[0036] A cyclone separator 6 is provided on one side of the intelligent lifting clamp 1, and a fan 7 is provided on one side of the cyclone separator 6.

[0037] A method for using a drill rod system includes the following steps: A smart lifting clamp 1 holds the drill rod 41, bringing the drill rod 41 into contact with a reducer 5. The reducer 5 is then rotated in the opposite direction to connect the drill rod 41. Similarly, the rotary drill bit 42 is connected to the drill rod 41. When connecting the second drill rod 41, the smart lifting clamp 1 is used to select a position to clamp the first section of the drill rod 41. At this time, a vision sorting system 2 scans the surface of the drill rod 41 to check for large particles embedded in the surface during drilling, preventing damage to the clamp and ensuring personal safety. Once large foreign objects are detected, an alarm is triggered and feedback is sent to the control system for surface cleaning. Then, the electrically controlled clamping and rotating mechanism 3... The upper end of the rotary drilling bit 42 is clamped and rotated counterclockwise to separate the rotary drilling bit 42 from the first drill rod 41. After complete separation, a stud is inserted to stop the rotation of the electrically controlled clamping mechanism 3 while maintaining the clamping posture. At the same time, the second drill rod 41-1 is connected, and the connection operation of the first drill rod 41 is repeated. During the drilling process, the blower 7 and the cyclone separator 6 extract the loess formed in the borehole from the hollow drill rod. The wind power generated by the blower 7 and the cyclone separator 6 provides power to the soil crushing device, cutting and crushing large soil clods that cannot be extracted due to their weight and volume. After being filtered through the filter screen 48, the soil is extracted and discharged, which effectively prevents the drill rod 41 from clogging.

[0038] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
