Description

Technical Field

[0001] The present invention relates to the technical field of exploration and drilling in deep earth, deep sea, deep space and polar regions, and particularly relates to a 3D printing type vehicle-mounted coiled tubing storage and transportation system. Background Art

[0002] Exploration and drilling technologies are important means for humans to obtain various mineral resources and soil and rock physical data from the earth and extraterrestrial planets. At present, the energy transmission of traditional exploration and drilling is mainly achieved through continuous cables and fluid pipelines, and the equipment for storing and transporting these long coiled tubings is mainly a drum-type winch. However, although the drum-type winch has excellent characteristics such as simple structure and large capacity, its serious deficiencies are that the conductive or current-carrying slip rings are extremely prone to failure, and the adjacent tubes on each layer are easily squeezed and bitten by each other, which easily causes damage and affects the normal operation and safety of the coiled tubing transmission terminal execution components. For this reason, the inventor proposed "a coiled tubing large-capacity storage and transportation device", see the patent number CN217327242U, which effectively solves the above problems.

[0003] However, the existing coiled tubing storage and transportation devices still have the following two deficiencies: ① Insufficient convenience. In practical applications, it is necessary to lay and install the foundation at the construction site in advance and fixedly install it on the foundation. After the construction is completed, it needs to be disassembled and then moved to the next construction site. Therefore, the preparation work before construction becomes more complicated, the time and cost increase, and thus the comprehensive cost increases. ② The coiled tubing storage and transportation principle adopted by the existing system, in the specific implementation process, the storage and transportation equipment needs to install conductive slip rings to complete the transition from the stationary end to the rotating end of the circuit. The system circuit is complex, and after the conductive slip rings are damaged, the maintenance and replacement are time-consuming and laborious. In order to effectively solve the above problems, a "3D printing type vehicle-mounted coiled tubing storage and transportation system" is proposed, which can move quickly at different construction sites and greatly reduce the preliminary preparation work. At the same time, the 3D printing motion principle is innovatively applied to the storage and extraction of coiled tubing, eliminating the dependence on conductive slip rings, simplifying the system circuit, and ensuring the safety and reliability of the circuit.

[0077] Please refer to Figure 1 shown, a 3D printing type vehicle-mounted coiled tubing storage and transportation system, including a coiled tubing storage sleeve 1, a coiled tubing pressing and anti-disengagement mechanism 2, a motion guide rail mechanism 3 and a coiled tubing storage and retrieval mechanism 4;

[0078] Please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 21 shown, the coiled tubing storage sleeve 1 as a whole presents a "straight notch shape", and is provided with a first installation position 101 and a second installation position 102 for installing the coiled tubing pressing and anti-disengagement mechanism 2, and 4 groups are symmetrically distributed. In addition, a coiled tubing transition area 103 is also provided on the coiled tubing storage sleeve 1 to facilitate the smooth storage and extraction of the coiled tubing 104. Combined with Figure 4It can be known that the storage path of the coiled tubing 104 in the coiled tubing storage sleeve 1 is: E-a-A-b-B-c-C-d-D-c-C-b-B-a-A-b. Correspondingly, when extracting the coiled tubing 104, its extraction path is exactly opposite to the storage path. The starting section of the coiled tubing 104 is fixed at the first fixed position 105 on the innermost side of the coiled tubing storage sleeve 1. The innermost sleeve radius of the coiled tubing storage sleeve 1 depends on the bending radius of the coiled tubing 104 to be stored, and the number of layers and spacing of the coiled tubing storage sleeve 1 depend on the pipe diameter of the coiled tubing 104 and the space size of the actual carrier vehicle body.

[0079] Please refer to Figure 1 and Figure 10 As shown, the coiled tubing storage sleeve 1 is fixedly connected to the vehicle body unit 301 in the moving guide rail mechanism 3 by bolts;

[0080] Please refer to Figure 1 、 Figures 5 to 8 As shown, the coiled tubing pressing and anti-disengagement mechanism 2 includes: a horizontal displacement driving motor 201, a slider mounting seat 202, a first slider 203, a first lead screw 204, a motor mounting plate 205, a vertical displacement driving motor 206, a lifter 207, a lifting lead screw 208, a pressing head 209, a motor mounting frame 210, a baffle driving motor 211, a first planar thrust bearing 212, a baffle 213 and a first roller 221;

[0081] The coiled tubing pressing and anti-disengagement mechanism 2 is integrally fixedly installed on the coiled tubing storage sleeve 1 and is symmetrically distributed in a total of 4 groups. During operation, each group cooperates with each other to jointly complete the actions of pressing the coiled tubing 104 into the coiled tubing storage sleeve 1 and preventing the coiled tubing 104 from disengaging from the coiled tubing storage sleeve 1;

[0082] Please refer to Figure 1 、 Figure 2 、 Figures 5 to 8As shown in the figure, the horizontal displacement drive motor 201 and the slider mounting seat 202 are both fixedly connected to the second mounting position 102 on the coiled tubing storage sleeve 1.

The first slider 203 is slidably connected to the slider mounting seat 202. Among them, the first trapezoidal projection 214 is sleeved with the first trapezoidal slideway 217, the first rectangular projection 215 is sleeved with the first rectangular slideway 218, and the second rectangular projection 216 is sleeved with the second rectangular slideway 219. The first rectangular projection 215 is provided with a first roller mounting groove 220. The first roller 221 is arranged in the first roller mounting groove 220 and is rotatably connected to the first rectangular projection 215. The second rectangular projection 216 is provided with a first lead screw through hole 222. The first lead screw 204 is installed in the second rectangular slideway 219, and the end of the first lead screw 204 is rotatably connected to the slider mounting seat 202. The head end of the first lead screw 204 is coaxially and fixedly connected to the horizontal displacement drive motor 201. The first lead screw 204 is in threaded cooperation with the first lead screw through hole 222. The horizontal displacement drive motor 201 drives the first slider 203 to perform reciprocating motion. In actual work, the first trapezoidal projection 214 and the first trapezoidal slideway 217 are provided to limit the freedom degree of the first slider 203 in other directions and only retain the horizontal movement in one direction. The first roller 221 is provided to reduce the frictional resistance generated during displacement;

[0083] Please refer to Figure 5 As shown in the figure, the motor mounting plate 205 is fixedly connected to the first slider 203. The vertical displacement drive motor 206 and the elevator 207 are both fixedly connected to the motor mounting plate 205, and the vertical displacement drive motor 206 and the elevator 207 are coaxially connected. The elevator lead screw 208 is threadedly connected to the elevator 207, and the pressure head 209 is fixedly connected to the elevator lead screw 208. During operation, the vertical displacement drive motor 206 drives the elevator 207, thereby driving the elevator lead screw 208 to move up and down, and at the same time driving the pressure head 209 to complete the action process of pressing the coiled tubing 104 into the coiled tubing storage sleeve 1;

[0084] Please refer to Figure 1 、 Figure 3 、 Figure 5As shown, the motor mounting bracket 210 is fixedly connected to the first mounting position 101. The baffle driving motor 211 is fixedly connected to the motor mounting bracket 210. The first planar thrust bearing 212 is fixedly connected to the motor mounting bracket 210. The baffle 213 is in contact with the first planar thrust bearing 212 and is fixedly connected to the rotating shaft of the baffle driving motor 211. During operation, the baffle driving motor 211 drives the baffle 213 to perform a sector motion, forming an obstacle above the coiled tubing storage sleeve 1, thereby preventing the coiled tubing 104 in the coiled tubing storage sleeve 1 from detaching from the coiled tubing storage sleeve 1 and causing a safety accident;

[0085] Please refer to Figure 7 、 Figure 8 As shown, furthermore, when installing the first lead screw 204 in the second rectangular slideway 219 and connecting the first roller 221 in the first roller mounting groove 220, appropriate bearings are correspondingly configured at the mounting hole positions to reduce the frictional resistance generated when the first roller 221 and the first lead screw 204 rotate;

[0086] Please refer to Figure 6 、 Figure 7 and Figure 9 It can be seen that during operation, the first slider 203 reciprocates under the drive of the horizontal displacement driving motor 201 and the first lead screw 204, and the set displacement stroke can fully meet the pressing requirements of the coiled tubing 104 at different positions;

[0087] Please refer to Figure 1 and Figure 10 It can be seen that the motion guide mechanism 3 includes: a vehicle body unit 301, a lifting and load-bearing unit 302, an auxiliary step unit 303, a support frame unit 304, a first motion unit 305, and a second motion unit 306;

[0088] Please refer to Figure 10 It can be seen that the vehicle body unit 301 and the lifting and load-bearing unit 302 are existing mature technologies and will not be elaborated here.

Due to the arrangement of the alignment rollers 406, the frictional resistance suffered by the coiled tubing 406 when passing through the alignment roller mounting bracket 405 can be greatly reduced.

In addition, through the above arrangement, the alignment roller mounting bracket 405 can be rotated at any angle, always consistent with the bending direction of the coiled tubing 104, ensuring the largest contact area between the coiled tubing 104 and the alignment rollers 406 to reduce the damage of the coiled tubing 104 to the alignment rollers 406;

[0099] To further illustrate, during operation, the corner adjustment motor 412 drives the driving gear 413, which drives the driven gear 414, and then drives all the components above the driven gear 414 in the coiled tubing conveying unit 404 to rotate slightly, so that the conveying chain 423 can always be directly opposite to the coiled tubing 104, ensuring that when the coiled tubing 104 is clamped, the conveying chain 423 and the coiled tubing 104 are in a state of maximum contact area. On the premise of ensuring that the clamping force meets the requirement of conveying the coiled tubing 104, the clamping damage of the conveying chain 423 to the coiled tubing 104 caused by the deflection of the coiled tubing 104 is minimized as much as possible;

[0100] To further illustrate, during operation, the clamping drive motor 417 drives the commutator 418, which then drives the clamping drive lead screw 419 to rotate, driving the left and right conveying motor mounting seats 420 to move back and forth towards each other, completing the clamping and releasing of the coiled tubing 104.

[0102] For further illustration, during the process of extracting the coiled tubing 104, the coiled tubing 104 itself will generate torsional deformation. Therefore, during the deformation recovery process, the coiled tubing 104 will exhibit warping.

[0104] For further illustration, the function of setting the first deep groove ball bearing 432 and the second deep groove ball bearing 442 is to reduce the circumferential friction resistance of the coiled tubing 104 on the tube-taking unit 401 when conveying the coiled tubing 104;

[0107] The working principle and use process of the present invention:

[0108] Working principle of coiled tubing storage sleeve 1:

[0109] In actual work, the coiled tube storage sleeve 1 provides space for storing the coiled tube 104. With the core purpose of storing the coiled tube 104, a coiled tube transition area 103 for passing the coiled tube 104 and a first installation position 101 and a second installation position 102 for installing the coiled tube pressing and anti-separation mechanism 2 are provided thereon. The coiled tube transition area 103 provides sufficient transition space for the reciprocating crossover storage of the coiled tube between the layers of the sleeves; the coiled tube pressing and anti-separation mechanism 2 installed thereon is responsible for pressing the coiled tube 104 into the sleeve and ensuring that the coiled tube will not separate from the sleeve.

[0110] Working principle of coiled tubing pressing and anti-separation mechanism 2:

[0111] In actual work, the coiled tubing pressing-in and anti-disengagement mechanism 2 is installed on the coiled tubing storage sleeve 1, and there are 4 groups symmetrically distributed. Taking the storage of coiled tubing 104 as an example, when the tubing storage and retrieval mechanism 4 moves close to a certain group of coiled tubing pressing-in and anti-disengagement mechanisms 2, first, the baffle driving motor 211 drives the baffle 213 to move, opening the path for the coiled tubing 104 to pass through. When the tubing storage and retrieval mechanism 4 drives the coiled tubing 104 to move away from this group of coiled tubing pressing-in and anti-disengagement mechanisms 2, the baffle driving motor 211 drives the baffle 213 to move, closing the path for the coiled tubing 104 to pass through. Then, the horizontal displacement driving motor 201 drives the slider mounting seat 202 to move, so that the pressing head 209 is exactly above the coiled tubing 104. After that, the vertical displacement driving motor 206 drives the elevator 207, and then drives the elevator lead screw 208 and the pressing head 209 to move downward, pressing the coiled tubing 104 into the coiled tubing storage sleeve 1. The tubing retrieval process is opposite to the tubing storage process. However, when retrieving the tubing, it is only necessary to open the baffle 213 in time when the coiled tubing 104 passes through, and close the baffle 213 in time when the coiled tubing 104 moves away.

[0112] Working principle of the motion guide rail mechanism 3:

[0113] In actual work, the motion guide rail mechanism 3 is used to control the movement of the tubing storage and retrieval mechanism 4, and the movement range needs to cover the coiled tubing storage sleeve 1. Specifically, the first motion unit 305 is slidably connected to the second motion unit 306, and a third lead screw through hole 321 is provided on the first truss support seat 309 in the first motion unit 305. A third lead screw 327 and a third driving motor 326 are provided in the second motion unit 306. The third lead screw through hole 321 is in threaded cooperation with the third lead screw 327. Therefore, driven by the third driving motor 326 and the third lead screw 327, the first motion unit 305 can achieve reciprocating movement. At the same time, the tubing storage and retrieval mechanism 4 is slidably connected to the first motion unit 305, and a second driving motor 311 and a second lead screw 312 are provided on the first truss 308 in the first motion unit 305. A second lead screw through hole 459 is provided on the tubing retrieval unit support seat 429 in the tubing storage and retrieval mechanism 4. The second lead screw 312 is threadedly connected to the second lead screw through hole 459. Therefore, driven by the second driving motor 311 and the second lead screw 312, the tubing storage and retrieval mechanism 4 can achieve reciprocating movement. To sum up, the tubing storage and retrieval mechanism 4 can achieve movement in two directions under the drive of the motion guide rail mechanism 3, and the movement range meets the requirements of tubing retrieval and storage.

[0114] Working principle of the tubing storage and retrieval mechanism 4:

[0115] In actual work, the pipe storage and extraction mechanism 4 is used to lower and extract the continuous pipe 104, which is specifically divided into the clamping and conveying process of the continuous pipe 104. The pipe storage and extraction mechanism 4 includes a pipe extraction unit 401 and an injection unit 402, and both of the above units include a continuous pipe conveying unit 404, and the clamping and conveying of the continuous pipe 104 are completed by the continuous pipe conveying unit 404. Specifically, first, the clamping drive motor 417 drives the clamping drive lead screw 419 through the commutator 418, and then drives the conveying motor mounting seat 420 threadedly matched with the clamping drive lead screw 419 to move toward each other, and at the same time drives the conveying motor 421, the conveying sprocket 422 and the conveying chain 423 fixedly installed on the conveying motor mounting seat 420 to move toward each other, completing the clamping of the continuous pipe 104. Then, the conveying motor 421 drives the conveying sprocket 422 and the conveying chain 423 to move, thereby driving the continuous pipe 104 to move. When the continuous tube 104 is lowered or taken out, it is only necessary to change the rotation direction of the conveying motor 421 .

[0116] Overview:

[0117] The 3D printing vehicle-mounted continuous pipe storage and transportation system comprises: a continuous pipe storage sleeve 1, a continuous pipe pressing and anti-separation mechanism 2, a motion guide mechanism 3 and a pipe storage and extraction mechanism 4. The present invention innovatively applies the 3D printing motion principle to the storage and extraction of continuous pipes 104. Taking the extraction of continuous pipes 104 as an example, during operation, the extraction unit 401 in the pipe storage and extraction mechanism 4 moves along the continuous pipe storage sleeve 1 under the drive of the motion guide mechanism 3, and at the same time, the continuous pipe 104 is clamped and transported with the cooperation of the continuous pipe conveying unit 404 in the pipe storage and extraction mechanism 4. In this process, the four groups of continuous pipe pressing and anti-separation mechanisms 2 are in a working state only when the extraction unit 401 approaches, and are switched to a closed state when the extraction unit 401 moves away, so as to ensure that the continuous pipe 104 to be extracted is always located in the continuous pipe storage sleeve 1, and will not be separated from the continuous pipe storage sleeve 1, causing a safety accident. In addition, storing and extracting the coiled tubing 104 are inverse processes to each other. Compared with extracting the coiled tubing 104 , storing the coiled tubing 104 adds a step of pressing the coiled tubing 104 into a sleeve.
