Description

Technical Field

[0001] This invention belongs to the field of drill pipe recycling technology, specifically a multi-specification adaptable automatic positioning anti-jamming drill pipe recycling chamber. Background Technology

[0002] In modern construction engineering, pile foundations are one of the most widely used foundation types, used to transfer the load of the superstructure to deep, stable soil or rock layers. Their quality is directly related to the safety and durability of the entire building. In order to verify key quality indicators such as the strength, integrity, uniformity of the pile concrete, pile length, and thickness of the sediment at the pile bottom.

[0003] Core drilling is a very intuitive and reliable testing method. It involves drilling concrete core samples from the pile body for observation, measurement, and compressive strength testing, providing direct evidence for project quality acceptance. The workflow is to use a large drilling rig equipped with a drill rod column made up of short drill rods connected together, with a diamond drill bit installed at the front end, and drill downwards from the top of the pile to continuously drill concrete core samples.

[0004] Currently, at pile foundation core drilling testing sites, there is no standardized dedicated equipment for the recovery and temporary storage of drill rods. The closest approach is very primitive, involving manual handling and ground stacking. This is the method used in the vast majority of testing sites. The work involves workers unscrewing the drill rods from the drill rod column next to the drilling rig, picking up or dragging individual drill rods away from the work area by hand or with simple hooks, and placing them directly on the ground or simply leaning them against the drilling rig frame or nearby components. As more drill rods are recovered, they are stacked parallel or crosswise on the ground, forming a messy "drill rod pile." Currently, the common methods for storing and recovering drill rods on site mostly rely on simple drill rod boxes, racks, or manual handling. These traditional methods have many limitations:

[0005] 1. Inefficiency: Workers need to manually loosen and unscrew the connecting threads of each drill rod. The drill rods are heavy, and loosening and unscrewing them is time-consuming and laborious.

[0006] 2. High labor intensity: Repetitive handling and unloading actions require high physical strength from workers;

[0007] 3. Safety hazards: The heavy drill rods pose a risk of falling and injuring feet during handling and placement. The oil and mud on the surface of the drill rods make operation slippery and inconvenient.

[0008] 4. Disorganized site: Recycled drill rods are usually piled up randomly on the ground, taking up space, affecting other operations, and are prone to collisions that can damage the delicate connecting threads;

[0009] 5. Drill rod damage: Random stacking and collisions may cause deformation and wear of the drill rod threads, affecting the connection sealing and verticality of the next use, thereby affecting the drilling quality.

[0010] 6. Poor adaptability: A set of facilities can usually only be used for drill pipes of a specific diameter and length. When the drilling task changes or the drill pipe specifications change, the storage device needs to be replaced or significantly adjusted, resulting in insufficient flexibility and long preparation time.

[0011] 7. Poor positioning and fixing effect: After the drill rod is retrieved, it is often placed only by gravity or simple slots. During equipment movement, road bumps or subsequent operations, it is very easy to roll, move or even slip, which poses a serious safety hazard and may also cause damage to the drill rod threads.

[0012] 8. Jamming is prone to occur, especially when retrieving drill rods with different straightness or with attached materials. Irregular friction and interference may occur at the contact point between the drill rod and the retrieval device, making it difficult to insert or remove the drill rod. This not only affects the smoothness of the operation, but may also cause mechanical damage to the equipment or drill rod due to forced operation. Summary of the Invention

[0013] The purpose of this invention is to integrate the three actions of "disassembly," "transfer," and "storage" into a single drill rod positioning mechanism. Workers no longer need to repeatedly move between the drilling rig and the storage point; simply rotating the drill rod chuck adjusts its position, quickly switching the empty space on the chuck to the working position, ready for the next drill rod to be inserted. This smooth operation saves time and reduces transport distance. Workers only need to unscrew the drill rod from the drilling rig and move it horizontally a short distance to place it in the drill rod chuck in the nearby recovery compartment, eliminating the need to carry heavy drill rods over long distances. Simultaneously, it optimizes the working posture; the height of the recovery compartment is adjustable, avoiding frequent and deep bending of workers to pick up or place drill rods from the ground, effectively reducing lower back strain and eliminating the risk of drill rod rolling. The drill rod is firmly held in the chuck, preventing it from rolling freely, completely avoiding the risk of foot injuries or tripping due to rolling drill rods. Furthermore, it standardizes the work area, storing messy drill rods in the equipment, keeping the work area around the drilling rig clean and unobstructed, and reducing the risk of ground obstructions. To prevent collisions and falls caused by obstructions, the movable sheet metal shell, mounting base, and equidistant positioning holes on the central shaft are mechanically fixed with bolts. The axial position of each component can be quickly adjusted, reliably accommodating drill rods of different lengths. The drill rod positioning mechanism provides a variety of drill rod mounting bases for selection and replacement. Its inherent toughness allows it to hold drill rods of different diameters, covering all drill rod diameter specifications. The detachable cone base and flat support plate design allows the recovery chamber to be flexibly fixed vertically to the ground or placed horizontally according to site space and operating habits, improving environmental adaptability. The braking mechanism, through gear meshing, enables synchronous drive of multiple screws, ensuring the positioning plate descends smoothly and without deviation. The positioning plate descends smoothly and fits the end of the drill rod, rigidly connecting the drill rod, mounting base, positioning plate, and the entire chamber into one unit, eliminating movement and collisions caused by loose or rotating parts during transportation or movement.

The turntable is also connected to the support component.

[0023] The outer casing mounting mechanism includes an outer casing mounting base, outer casing positioning bolts, and outer casing mounting screw holes. The outer casing mounting base is fixedly connected to the top of the movable sheet metal outer casing. Multiple outer casing mounting screw holes are provided, and the multiple outer casing mounting screw holes are equally spaced on the outer casing mounting base. Multiple outer casing positioning bolts are provided, and each outer casing positioning bolt is threaded into each outer casing mounting screw hole. The multiple outer casing positioning bolts are movably connected into one set of positioning holes.

[0024] The movable mounting component includes a fixing component and a card holder mounting base. The card holder mounting base is movably connected to the central shaft. The fixing component is provided in two sets, which are respectively located at both ends of the card holder mounting base, and the two sets of fixing components are respectively connected to two sets of positioning holes.

[0025] Each set of fixing components includes a card seat positioning bolt and a card seat mounting screw hole. There are multiple card seat mounting screw holes, which are equidistantly opened on the card seat mounting base. There are multiple card seat positioning bolts, each of which is threaded into each card seat mounting screw hole, and the multiple card seat positioning bolts are movably connected into one set of positioning holes.

[0026] The positioning component includes a limiting component, a synchronizing component, and lifting screws. The limiting component is located inside the movable sheet metal housing. Multiple lifting screws are provided, and each lifting screw is equidistantly rotatably connected to the movable sheet metal housing.

[0027] The limiting component is a limiting plate, and there are multiple limiting plates. The multiple limiting plates are fixedly connected at equal intervals inside the movable sheet metal shell, and the positioning plate is slidably connected to the multiple limiting plates.

[0028] The synchronization component includes a linkage gear and a synchronization gear. A drive cavity is provided at the top of the movable sheet metal shell.

[0032] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0033] (1) In this invention, the three actions of “disassembly”, “transfer” and “storage” are integrated into a drill rod positioning mechanism. Workers do not need to run back and forth between the drilling machine and the stacking point. They can adjust the position by rotating the drill rod chuck and quickly switch the empty space on the drill rod chuck to the working position, waiting for the next drill rod to be put in. The operation is smooth and saves time.

[0034] (2) In this invention, the carrying distance is reduced. After the worker unscrews the drill rod from the drilling machine, he can move it horizontally a very short distance to put it into the drill rod holder in the recovery compartment next to him. There is no need to carry the heavy drill rod over a long distance. At the same time, the working posture is optimized. The height of the recovery compartment can be adjusted to avoid the worker frequently bending over deeply to pick up or place the drill rod from the ground, effectively reducing lumbar strain.

[0035] (3) In this invention, the risk of drill rod rolling is eliminated. The drill rod is firmly locked in the drill rod holder and cannot roll at will. This completely avoids the risk of the drill rod rolling and injuring the feet or tripping people. At the same time, it standardizes the work area, stores messy drill rods in the equipment, keeps the work area around the drilling machine clean and unobstructed, and reduces the risk of collisions and falls caused by ground obstacles.

[0036] (4) In this invention, the movable iron shell, the card seat mounting base and the equidistant positioning holes on the central shaft are matched and mechanically fixed with bolts, so that the position of each component in the axial direction can be quickly adjusted, thereby reliably adapting to drill rods of different lengths.

[0037] (5) In this invention, by using the drill rod positioning mechanism, a variety of drill rod holders of different sizes are provided for selection and replacement. Its own toughness enables it to hold drill rods of different diameters, thereby covering the diameter specifications of drill rods.

[0038] (6) In this invention, the design of the detachable cone seat and the flat support plate allows the recovery bin to be flexibly fixed vertically on the ground or placed horizontally according to the site space and working habits, thereby improving environmental adaptability.

[0039] (7) In this invention, by using a braking mechanism, the multi-screw synchronous drive is achieved through gear meshing, which ensures that the positioning plate descends smoothly and without deviation, so that the positioning plate descends smoothly and fits the end of the drill rod, and the drill rod, the chuck, the positioning plate and the entire cabin are rigidly connected as one, eliminating the movement and collision caused by loosening or rotating of parts during transportation or movement.

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0050] Example 1, refer to Figure 1-8 A multi-size adaptable automatic positioning and anti-jamming drill pipe recovery chamber, comprising:

[0051] Fixed iron outer casing 1;

[0052] Central shaft 8 is fixedly connected to the center of the fixed sheet metal outer casing 1;

[0053] Positioning holes 9 are provided in multiple sets, and all sets of positioning holes 9 are equally spaced on the central shaft 8;

[0054] The movable sheet metal casing 13 is movably connected to the central shaft 8;

[0055] The outer casing mounting mechanism is located on the movable sheet metal outer casing 13, and the outer casing mounting mechanism is connected to the positioning hole 9;

[0056] The drill pipe positioning mechanism is provided in two sets. Both sets of drill pipe positioning mechanisms are located on the central shaft 8. Each set of drill pipe positioning mechanisms includes a movable mounting component and a drill pipe chuck 12. The movable mounting component is located on the central shaft 8, and the drill pipe chuck 12 is mounted on the movable mounting component.

[0057] The braking mechanism is located inside the movable sheet metal housing 13. The braking mechanism includes an adjusting component and a positioning disk 17. The adjusting component is located inside the movable sheet metal housing 13, and the positioning disk 17 is movably connected inside the movable sheet metal housing 13 and is connected to the adjusting component.

[0058] The rotating mechanism is located inside the fixed iron shell 1. The rotating mechanism includes a support component and a turntable 6. The support component is located inside the fixed iron shell 1, and the turntable 6 is rotatably connected to the bottom of the fixed iron shell 1. The turntable 6 is connected to the support component.

[0059] In this implementation scheme: the fixed iron shell 1 is fixedly connected to the central shaft 8. The positioning holes 9 are evenly distributed on the central shaft 8. The movable iron shell 13 is installed at different positions on the central shaft 8 through the shell mounting mechanism and the positioning holes 9 to accommodate different drill rod lengths. The drill rod holder 12 has different sizes to accommodate drill rods of different diameters. In addition, the drill rod holder 12 has a certain degree of toughness, which can make the drill rod stuck inside the drill rod holder 12 to ensure stability. At the same time, the structure of the drill rod holder 12 can be changed to improve the flexibility during use. The positioning plate 17 has holes to connect with the drill rod to realize the positioning of the drill rod after recovery, so as to avoid the overall stability being affected by the rotatable characteristics of the drill rod holder 12 during movement. The turntable 6 facilitates the rotation of the drill rod when the device is used vertically.

[0060] Specifically: The outer casing mounting mechanism includes an outer casing mounting base 21, an outer casing positioning bolt 19, and an outer casing mounting screw hole 22. The outer casing mounting base 21 is fixedly connected to the top of the movable sheet metal outer casing 13. There are multiple outer casing mounting screw holes 22, which are equidistantly opened on the outer casing mounting base 21. There are multiple outer casing positioning bolts 19, each of which is threaded into each outer casing mounting screw hole 22, and all of the multiple outer casing positioning bolts 19 are movably connected into one set of positioning holes 9.

[0061] In this embodiment, the outer casing mounting base 21, the outer casing positioning bolt 19, and the outer casing mounting screw hole 22 cooperate with each other. By rotating the outer casing positioning bolt 19 in the outer casing mounting screw hole 22, the outer casing positioning bolt 19 extends and retracts in the corresponding positioning hole 9, so as to realize the installation of the movable sheet metal outer casing 13 at different positions on the central shaft 8 to adapt to the use of drill rods of different lengths.

[0062] Specifically: The movable mounting component includes a fixing component and a card holder mounting base 11. The card holder mounting base 11 is movably connected to the central shaft 8. There are two sets of fixing components, which are respectively located at both ends of the card holder mounting base 11, and the two sets of fixing components are respectively connected to two sets of positioning holes 9.

[0063] In this embodiment, the drill pipe chuck 12 is rotatably connected to the center position of the chuck mounting base 11 to ensure the balance of both ends of the chuck mounting base 11. At the same time, in conjunction with the turntable 6, it facilitates position adjustment during the drill pipe retrieval process.

[0064] Specifically: Each set of fixing components includes a card seat positioning bolt 10 and a card seat mounting screw hole 25. There are multiple card seat mounting screw holes 25, which are equidistantly opened on the card seat mounting base 11. There are multiple card seat positioning bolts 10, each of which is threaded into each card seat mounting screw hole 25, and the multiple card seat positioning bolts 10 are movably connected into one set of positioning holes 9.

[0065] In this embodiment, the locating bolt 10 and the mounting screw hole 25 cooperate with each other. By rotating the locating bolt 10 in the mounting screw hole 25, the locating bolt 10 extends and retracts in the locating hole 9, so as to realize the installation of the locating mounting seat 11 at different positions on the central shaft 8, so as to adapt to the recovery of drill rods of different lengths.

[0066] Specifically: The positioning component includes a limiting component, a synchronizing component, and a lifting screw 14. The limiting component is located inside the movable sheet metal housing 13. Multiple lifting screws 14 are provided, and all of the multiple lifting screws 14 are equidistantly rotatably connected inside the movable sheet metal housing 13. All of the multiple lifting screws 14 are threadedly connected to the positioning plate 17. A drive block 24 is fixedly connected to the top of one of the lifting screws 14. The synchronizing component is located inside the movable sheet metal housing 13 and is connected to the multiple lifting screws 14.

[0067] In this embodiment: the lifting screw 14 rotates, controlling the positioning disk 17 to rise and fall within the movable sheet metal outer shell 13, so that the positioning disk 17 is fitted onto one end of the drill rod, thereby restricting the drill rod and preventing it from rotating during movement. The drive block 24 docks with external components to complete the rotation control of the lifting screw 14.

[0068] Specifically: the limiting component is a limiting plate 20, and there are multiple limiting plates 20. The multiple limiting plates 20 are fixedly connected at equal intervals inside the movable iron shell 13, and the positioning plate 17 is slidably connected to the multiple limiting plates 20.

[0069] In this embodiment, the limiting plate 20 restricts the lifting and lowering of the positioning plate 17, so that the positioning plate 17 can only be lifted and lowered, but cannot be rotated, and works in conjunction with the lifting screw 14 to complete the use.

[0070] Specifically: The synchronization component includes a linkage gear 15 and a synchronization gear 16. A drive cavity 23 is provided at the top of the movable sheet metal shell 13. The linkage gear 15 is rotatably connected to the drive cavity 23. There are multiple synchronization gears 16. Each synchronization gear 16 is fixedly connected to the top of each lifting screw 14, and the multiple synchronization gears 16 mesh with the linkage gear 15.

[0071] In this embodiment, the synchronous gears 16 are of the same size. The linkage gear 15 enables multiple synchronous gears 16 to rotate synchronously, thereby enabling multiple lifting screws 14 to rotate synchronously and achieving stable lifting and lowering of the positioning disk 17.

[0072] Specifically: The support components include ball grooves 2, rotating balls 5, and pressure plates 26. There are multiple ball grooves 2, which are all opened at the bottom of the fixed iron shell 1 and are evenly distributed. There are multiple rotating balls 5, each of which is rotatably connected to each ball groove 2. The pressure plates 26 are fixedly connected to the bottom of the central shaft 8 and are located directly above the turntable 6.

[0073] In this embodiment, the ball groove 2 and the rotating ball 5 cooperate with each other to make the turntable 6 rotate smoothly and realize the recovery of the drill rod. The pressure plate 26 limits the height of the turntable 6 to ensure the stability of the turntable 6 in use.

[0074] Specifically: a flat support plate 18 is fixedly connected to one edge of the outer surface of both the fixed iron shell 1 and the movable iron shell 13, and a drill rod insertion port 7 is opened on one side of the outer surface of both the fixed iron shell 1 and the movable iron shell 13.

[0075] In this embodiment: the flat support plate 18 allows the entire device to be placed horizontally, increasing its versatility; the drill rod inlet 7 makes it easier to insert the drill rod into the fixed sheet metal casing 1 and the movable sheet metal casing 13, thus completing the drill rod retrieval.

[0076] Specifically: a slot 3 is provided at the bottom of the fixed iron shell 1, and a conical seat 4 is movably inserted into the slot 3.

[0077] In this embodiment, the cone seat 4 is movably connected to the slot 3, so that the cone seat 4 and the fixed iron shell 1 form an integral whole, ensuring the stable use of the device in the vertical direction.

[0078] In use, select the corresponding drill rod chuck 12 according to the diameter of the drill rod to be recovered, and put the chuck mounting base 11 on the central shaft 8. Adjust the position of the chuck mounting base 11 on the central shaft 8 according to the length of the drill rod to be recovered. Rotate the chuck positioning bolt 10 in the chuck mounting screw hole 25 so that one end of the chuck positioning bolt 10 is inserted into the corresponding positioning hole 9 to complete the installation of the drill rod chuck 12. Put the movable sheet metal shell 13 on the central shaft 8. Move the movable sheet metal shell 13 according to the length of the drill rod to be recovered. Rotate the shell positioning bolt 19 in the shell mounting screw hole 22 so that one end of the shell positioning bolt 19 is inserted into the corresponding positioning hole 9 to complete the installation of the movable sheet metal shell 13. Depending on the site work space and habits, choose to place the entire recovery chamber vertically or horizontally. When placed vertically, install the cone seat 4 in the slot 3 and insert the cone seat 4 into the ground to realize the use of the device. When placed horizontally, place the flat support plate 18 on the fixed sheet metal shell 1 and the movable sheet metal shell 13 on the ground to keep it in place. To ensure the device is stable, align one end of the drill rod with the drill rod inlet 7 on the fixed iron shell 1, placing one end of the drill rod on the turntable 6. Rotate the two drill rod holders 12, pressing the drill rod into the holders 12, allowing them to grip and position it. After the drill rod is fully retracted, it connects to the drive block 24 via external components and rotates, causing one of the lifting screws 14 to rotate. This rotation is then transmitted through the meshing of multiple synchronous gears 16 and linkage gears 15, causing all the lifting screws to rotate. The rod 14 rotates synchronously, cooperating with the limiting plate 20 to make the positioning plate 17 descend smoothly until the docking hole on the positioning plate 17 fits the end of the drill rod. At this time, the drill rod is completely restricted, effectively preventing the drill rod from rotating or moving axially during movement and transportation, thus completing the recycling operation. When taking it out, the lifting screw 14 is rotated in the opposite direction by the drive block 24 to make the positioning plate 17 disengage from the drill rod. The drill rod holder 12 is rotated to rotate the drill rod to the drill rod inlet 7, and the drill rod is pulled out smoothly to complete the extraction operation.

[0079] The control method of this invention is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this invention is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
