Description

Technical Field

[0001] The present invention belongs to the field of drilling rigs, and particularly relates to a full-automatic auxiliary rod-changing box. Background Art

[0002] A horizontal directional drill is a construction machine for laying various underground public facilities (pipelines, cables, etc.) without excavating the ground surface. It is widely used in the construction of flexible pipelines such as water supply, electricity, telecommunications, natural gas, coal gas, and petroleum. It is suitable for geological conditions such as sandy soil and clay, and is not suitable for areas with relatively high groundwater levels and pebble strata. Most non-hard rock areas in China can be constructed. The working environment temperature is -15°C to +45°C. The horizontal directional drilling technology is a new construction technology that combines the directional drilling technology in the petroleum industry with the traditional pipeline construction method. It has the advantages of fast construction speed, high construction accuracy, and low cost, and is widely used in pipeline laying construction projects such as water supply, gas, electricity, telecommunications, natural gas, and petroleum. The horizontal directional drilling equipment has also developed rapidly in the past ten years and has become an emerging industry in developed countries. Its development trend is towards large-scale and miniaturization, adaptation to hard rock operations, self-contained anchoring systems, automatic stacking and extraction of drill pipes, automatic lubrication of drill pipe connections, automated operation functions such as anti-electric shock systems, ultra-deep guidance monitoring, and wide application ranges. This type of equipment is generally suitable for steel pipes and PE pipes with a pipe diameter of φ300 to φ1200mm, and the maximum pipe laying length can reach 1500m. It is suitable for various soil conditions from soft soil to hard rock, and has broad application prospects.

[0003] During the construction process of a horizontal directional drilling rig, drill pipes need to be added multiple times. For medium and small-sized drilling rigs, due to more frequent pipe changing, semi-automatic auxiliary pipe-changing devices and fully automatic auxiliary pipe-changing devices are mainly configured to replace manual pipe changing, reduce labor intensity, and improve construction efficiency. Although the existing semi-automatic auxiliary pipe-changing device has no limit on the number of connected pipes and does not affect the construction distance, it requires 2 workers during construction, with a large labor intensity. Moreover, manual handling takes time and labor costs, and the pipe connection and replacement efficiency is not high. While the existing fully automatic pipe-changing device does not require manual handling of drill pipes, saving manpower and time, its drill pipe box has a limited volume, and the number of drill pipes stored is also limited to maintain the balance of the machine, resulting in an insufficient total number of drill pipes that the drill pipe box can accommodate, thus affecting the construction distance. During the construction process, it is often necessary to add drill pipes temporarily. The drill pipe box is installed on the machine's girder, at a relatively high position, generally about 1.6 meters above the ground. When adding drill pipes, 2 workers must climb up and drop the drill pipes one by one from the gaps at the top of the drill pipe box. Inevitably, when the drill pipes fall into the drill pipe box, they will collide with other drill pipes, easily damaging the drill pipes and threads. During the climbing process, the workers not only have a large labor intensity but also are prone to safety accidents. When the machine is transported by truck and travels long distances, to ensure the balance of the machine and the safety of getting on and off the vehicle, all the drill pipes in the drill pipe box need to be unloaded. The existing fully automatic drill pipe box only has the function of discharging pipes towards the inner side of the machine. When unloading the pipes, due to the obstruction of the drill pipe box, they can only be wound out from the girder on the inner side of the machine, which is cumbersome and time-consuming. The process of adding or removing drill pipes from the drill pipe box must be operated with the machine stopped, affecting the construction progress.

[0004] Moreover, during the working process of the existing fully automatic pipe-changing device, since the drill pipe is as long as 3 meters, the lifting of the drill pipe is completed by at least two drill pipe brackets (fulcrums). The rod-supporting mechanism of the existing technology is that each of the two drill pipe brackets is connected to a hydraulic cylinder. The telescopic movement of the hydraulic cylinder is used to push the drill pipe bracket to complete the up and down lifting action of the drill pipe, and then the synchronization of the actions of the two hydraulic cylinders is controlled by adjusting the flow rate of the hydraulic oil flowing in and out of the hydraulic cylinders. This structure can only be manually adjusted by visual inspection and experience. In actual use, there is always a certain difference in the control of the flow rate of the hydraulic oil in the two hydraulic cylinders. The synchronization control effect of the two hydraulic cylinders is not ideal. The lifting actions of the two drill pipe brackets often appear to be uneven in speed, and the lifting heights cannot be accurately synchronized, resulting in inconsistent heights at both ends of the drill pipe, and the drill pipe is prone to deflect and slide towards the end with a lower height, interfering with the surrounding structural components, causing jamming or even failure of the up and down pipe actions, and the drill pipe is squeezed and deformed, thus affecting the construction efficiency. Summary of the Invention

[0018] 1. The storage mechanism and the fixing mechanism of the present invention are detachably installed, which is convenient for placing drill pipes into the storage mechanism. The transportation mechanism can transport the drill pipes in the storage mechanism to the manipulator of the drilling rig, realizing full automation throughout the process and improving the working efficiency.

[0019] 2. The present invention designs the existing two independent drill pipe brackets as a linkage mechanism, and on this basis, multiple groups of drill pipe brackets can be set according to the length of the drill pipe. The rigid connection between adjacent drill pipe brackets accurately ensures the complete consistency of the lifting actions of two adjacent drill pipe brackets, thereby ensuring the realization of the linkage effect between multiple groups of drill pipe brackets, ensuring that the drill pipe can rise and fall horizontally, avoiding the problems of jamming and extrusion deformation when the drill pipe moves up and down in the drill pipe box, and improving work efficiency; and the present invention only needs to use one driving device to control multiple groups of drill pipe brackets, instead of one driving device for each drill pipe bracket as before, saving manufacturing and assembly costs and having good economy.

[0052] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following describes the detailed implementation manners of the present invention clearly and completely with reference to the accompanying drawings.

[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0055] As shown Figure 1 in the figure, it is an existing horizontal directional drill. During the working process, the drill pipe 6 needs to be connected multiple times. The existing drill pipe replacement method requires manual disassembly and assembly of the drill pipe 6. This method not only has a high labor intensity, but also requires time and labor costs for manual handling, and the efficiency of replacing and connecting the drill pipe is not high.

[0056] As shown Figure 2 in Figure 3 the figure, a fully automatic auxiliary drill pipe changing box provided in this embodiment is installed on the same side of the drill manipulator. It can not only automatically transport the drill pipe 6 to the manipulator, but also automatically supplement or remove the drill pipe in the drill pipe box 42, without the need to manually load, take out and transport the drill pipe in the drill pipe box 42, which is more efficient and safe; and through the transport mechanism 2, new drill pipes can be continuously provided to the manipulator to ensure the working efficiency.

[0057] As shown Figure 4 in the figure, the specific structure is as follows: it includes a storage mechanism 4 for storing and placing drill pipes, a plurality of transport mechanisms 2 for transporting the drill pipes in the storage mechanism 4, a rod supporting mechanism 3 for lifting the drill pipes in the storage mechanism 4, a first driving mechanism 1 for providing power to the plurality of transport mechanisms 2 at the same time, and a fixing mechanism 5 for installing the storage mechanism 4, the transport mechanism 2, the rod supporting mechanism 3, and the first driving mechanism 1; the storage mechanism 4 is detachably installed above the fixing mechanism 5; the transport mechanism 2 is located below the storage mechanism 4, and the top of the transport mechanism 2 is flush with the bottom of the storage mechanism 4; the rod supporting mechanism 3 is located below the transport mechanism 2; the highest lifting point of the rod supporting mechanism 3 is higher than the bottom position of the storage mechanism 4.

[0058] As shown Figure 5 in the figure, in this embodiment, the first driving mechanism 1 includes a first driving device 11, a first driving rod 12, and a transmission mechanism 13; the first driving device 11 is fixed on the fixing mechanism 5 through a first mounting frame 14; the output shaft of the first driving device 11 is connected to the first driving rod 12; a plurality of transmission mechanisms 13 for controlling the movement of the transport mechanism 2 are provided on the first driving rod 12. In a specific implementation, the first driving device 11 is a driving motor, the output shaft of the driving motor is connected to the first driving rod 12 to control the rotation of the first driving rod 12, and the transmission mechanism 13 is fixed on the first driving rod 12. By starting the driving motor, the synchronous transmission of the plurality of transmission mechanisms 13 can be achieved at the same time. In this embodiment, the transmission mechanism 13 can be a gear transmission, a belt transmission, etc. The gear transmission method is preferably used. The transmission mechanism 13 is a gear, and the gear is fixedly arranged on the first driving rod 12 and corresponds to the number of transport devices 2 one by one. By controlling the rotation of the gear through the first driving rod 12, the transport device 2 meshed with the gear can be controlled to move.

[0059] As shown Figure 11 inFigure 12 As shown, in this embodiment, the transport mechanism 2 includes a moving block 23; a placement block 25 is fixed to the top of the moving block 23, and the placement block 25 is flush with the bottom of the storage mechanism 4. Among them, the length of the placement block 25 is greater than the width of the storage mechanism 4, so as to provide a displacement capacity for the left and right fine adjustment of the placement block 25, and avoid the placement block 25 being too short to always abut against the bottom of the storage mechanism 4 during the movement, resulting in the drill pipe located in the storage mechanism 4 falling; the moving block 23 is arranged on the fixing mechanism 5 through the second mounting bracket 27; one end of the moving block 23 is fixed with a receiving block 26; a limiting mechanism 24 for restricting the drill pipe located in the receiving block 26 from moving out is arranged on the moving block 23; the bottom of the moving block 23 is cooperatively connected with the transmission mechanism 13. In this embodiment, teeth that can mesh with the gear are arranged at the bottom of the moving block 23. The first driving device 11 is started, so as to simultaneously control the synchronous transmission of multiple gears, and then the moving block 23 moves synchronously under the transmission of the gears.

[0060] As Figure 4 、 Figure 5 shown, in this embodiment, a first receiving groove 22 for placing the drill pipe is arranged on the placement block 25 of the transport mechanism 2, and a detachable cushion block 21 is placed in the first receiving groove 22.

[0061] As Figure 12 shown, in this embodiment, the limiting mechanism 24 includes a second driving device 241 and a first stop block 247; a receiving groove 261 for receiving the drill pipe is arranged on the receiving block 26; the first stop block 247 is located above the receiving groove 261; the first stop block 247 is connected with the second driving device 241. In the specific implementation manner, the receiving groove 261 is in a 3 / 4 arc shape. When the drill pipe falls into the receiving groove 261, the second driving device 241 controls the first stop block 247 to be above the receiving groove 261, and forms a clamping assembly with the receiving groove 261 to fix the drill pipe in the receiving groove 261 to prevent it from falling during transportation.

[0062] As Figure 13As shown, in another embodiment, the limiting mechanism 24 further includes a first connecting block 242; the first connecting block 242 is slidably disposed at the bottom of the storage block 25 or the side surface of the moving block 23; one end of the first connecting block 242 is connected to the first stopper 247, and the other end is connected to the second driving device 241; the first connecting block 242 is further connected to the receiving block 26 through a spring 245. In a specific implementation, a fourth hook 262 is provided on the receiving block 26, a first hook 243 is provided on the first connecting block 242, and third hooks 246 that cooperate with the fourth hook 262 and second hooks 244 that cooperate with the first hook 243 are respectively provided at both ends of the spring 245. When the second driving device 241 controls the first stopper 247 to move away from the receiving block 26, the spring 245 is stretched under the action of the first connecting block 242. When the second driving device 241 controls the first stopper 247 to return to the clamping state, the first stopper 247 is also subjected to the elastic force of the spring 245, so as to avoid that even if the second driving device 241 fails during the clamping process, the clamping state can still be maintained, ensuring that the drill pipe will not fall off and ensuring the safety of the staff.

[0063] In a specific operation, if the transportation mechanism 2 is a one-way rod loading method, then the first receiving groove 22 is not provided on the moving block 23, or a cushion block 21 is placed in the provided first receiving groove 22. At this time, the receiving block 26 of the transportation mechanism 2 is located below the outermost group of drill pipes of the storage mechanism 4, and the highest point of the rod supporting mechanism 3 is located below the storage block 25 of the transportation mechanism 2. Since the storage block 25 is flush with the bottom of the storage mechanism 4, that is, the storage block 25 and the lowest point of the storage mechanism 4 are on the same horizontal plane. At this time, the drill pipes in the storage mechanism 4 will fall onto the storage block 25, and the outermost drill pipe will fall onto the receiving block 26. Then move the transportation mechanism 2 to move the receiving block 26 out of the storage mechanism 4. For the drill pipes above the removed drill pipe, because the storage block 25 replaces the position of the receiving block 26, they will fall onto the storage block 25. At the same time, the storage block 25 also replaces the rod supporting mechanism 3 to support the other drill pipes located in the storage mechanism 4, thus completing the preparation for the feeding of the drill pipes; then start the rod supporting mechanism 3 to make its highest point located above the storage block 25 of the transportation mechanism 2, and lift the drill pipes located on the storage block 25 to facilitate the movement of the transportation mechanism 2 to transport the drill pipes in the receiving block 26.

[0064] As Figure 11 , Figure 14 , Figure 15As shown, the transport mechanism 2 is a two-way upward rod method, that is, not only a receiving block 26 is provided on the moving block 23, but also a first receiving groove 22 is provided on the placing block 25. At this time, the drill pipe transportation and the drill pipe addition can be completed simultaneously. The transportation of the drill pipe includes the process of transporting it down to the drill rig and the unloading process. The process of transporting it to the drill rig is for the drill pipes located in the receiving block 26, while the unloading process is for the drill pipes in the first receiving groove 22. The feeding preparation is the same as that of the one-way upward rod method. The difference between the two lies in the transportation direction, so it will not be described here; for the drill pipe addition, the rod supporting mechanism 3 is in the state of lifting the drill pipe at this time. Move the first receiving groove 22 out from below the storage mechanism 4, then place the drill pipe into the first receiving groove 22, and then move the first receiving groove 22 back under the storage mechanism 4. At this time, control the rod supporting mechanism 3 to descend below the placing block 25. The drill pipes in the storage mechanism 4 fall onto the placing block 25 or on top of the drill pipes in the first receiving groove 22. Then control the rod supporting mechanism 3 to rise and lift all the drill pipes to complete the addition of the drill pipes. In specific operations, the drill pipes in the receiving block 26 fall in the order from the outside to the inside, while for the drill pipes in the first receiving groove 22, as long as the placing block 25 outside the first receiving groove 22 is long enough, there is no need to follow the order.

[0065] As Figure 7 shown, in this embodiment, the rod supporting mechanism 3 includes a third driving device 32 and multiple groups of drill pipe brackets 33; the third driving device 32 is arranged on the fixing mechanism 5 through a third mounting frame 31, and the third driving device 32 is hingedly connected to the third mounting frame 31; one end of the drill pipe bracket 33 is hingedly connected to the fixing mechanism 5; the free end of the drill pipe bracket 33 close to the third driving device 32 is hingedly connected to the output shaft of the third driving device 32; a linkage rod 35 is arranged between two adjacent drill pipe brackets 33; both ends of the linkage rod 35 are hingedly arranged with the drill pipe brackets 33 it is connected to; the top of the drill pipe bracket 33 is higher than the bottom of the storage mechanism 4 at the highest point of movement.

[0066] As Figure 6 、 Figure 7 、 Figure 10 shown, the third driving device 32 adopts a hydraulic cylinder. The third driving device 32 can rotate around the third mounting frame 31, the output shaft of the third driving device 32 can rotate around the drill pipe bracket 33, and the drill pipe bracket 33 rotates around the fixing mechanism 5. Both ends of the linkage rod 35 rotate around the drill pipe bracket 33 respectively, thus forming a set of linkage mechanisms. Start the third driving device 32, the output shaft of the third driving device 32 extends, and then pushes the drill pipe bracket 33 to rotate around the fixing mechanism 5, and through the linkage rod 35, pushes the adjacent drill pipe brackets 33 to rotate. When moving to the highest point, the top of the drill pipe bracket 33 is higher than the placing block 25 of the transport mechanism 2. At this time, the drill pipes on the placing block 25 can be lifted to facilitate the movement of the transport mechanism 2 loaded with drill pipes to send the drill pipes to the manipulator of the drill rig.

[0067] As shown Figure 8 , Figure 9 , Figure 10 After reaching the highest point, the third driving device 32 is activated, and the output shaft of the third driving device 32 contracts, thereby pulling the drill pipe bracket 33 to rotate around the fixing mechanism 5. The adjacent drill pipe brackets 33 are pulled to rotate through the linkage rod 35. Finally, the top of the drill pipe bracket 33 is lower than the placing block 25 of the transportation mechanism 2. At this time, the drill pipe drops into the receiving groove 261 of the placing block 25 and the receiving block 26, preparing the materials for transporting the drill pipe to the drill rig.

[0068] As shown Figure 16 , Figure 17 In this embodiment, the drill pipe bracket 33 is composed of multiple bracket units; each bracket unit is composed of two first lifting blocks 336 arranged in parallel and a second lifting block 337 perpendicular to the first lifting blocks 336.
