Description

Technical Field

[0001] The present invention relates to the fields of drilling, well drilling engineering, road and bridge, ocean, aerospace, polar region, urban underground construction and rescue, etc., and particularly relates to a coiled tubing large-capacity storage and transportation device. Background Art

[0002] At present, the application of coiled tubing is becoming more and more extensive. Especially for the multi-channel and multi-functional coiled tubing containing fiber optic cables, it plays a key role in many fields such as drilling, well drilling engineering, road and bridge, ocean, aerospace, polar region, urban underground construction and rescue. Currently, the mature coiled tubing storage and release equipment is mainly winches or hoists. For the load-bearing continuous steel rope type hoist, it is convenient and fast to use. For the winch of the multi-channel and multi-functional coiled tubing with electric cables, there are many problems in use. The main problems are as follows: First, in addition to bearing force, the coiled tubing also needs to transmit fluids, electricity or signals, etc. It is necessary to set up a dynamic and static sealing mechanism with excellent performance to transmit fluids, electricity or signals with the static ground. This mechanism is called a multi-channel slip ring. A stable multi-channel slip ring that can transmit fluids, electricity and signals is a worldwide problem. Second, the capacity of the coiled tubing is small. Because the bending diameter of the rigid coiled tubing with a relatively large diameter is large, its capacity on the reel is naturally not large, and the equipment is huge, making transportation difficult. Third, the large-diameter rigid coiled tubing frequently buckles and straightens on the reel slightly larger than its minimum bending diameter, and its fatigue life is short. Fourth, the coiled tubing storage method of the reel type is extremely prone to mutual extrusion deformation and abnormal damage.

[0003] Therefore, it is very necessary and of great significance to develop a coiled tubing large-capacity storage and transportation device that can effectively solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to address the problems and deficiencies described in the background art and originally create a coiled tubing large-capacity storage and transportation device.

At the same time, it increases the functions of strong downward pressure and upward lifting, and auxiliary lifting and lowering of larger-diameter terminal tools or instruments that need to be connected to the coiled tubing for transportation, making it more green, efficient, intelligent and environmentally friendly.

[0070] Referring to the attached drawings, a coiled tubing large-capacity storage and transportation device includes a gooseneck reversing mechanism 1, a storage and injection mechanism 2, a slewing support mechanism 3, an auxiliary clamping and lifting mechanism 4, a storage and placement guiding mechanism 5, a pipe storage sleeve automatic alignment mechanism 6, a traction electric control trolley 7, a sleeve-type large-capacity pipe storage mechanism 8, a coiled tubing 9, and a hoisting electric hoist 10;

[0071] The gooseneck reversing mechanism 1 includes a coiled tubing centering sleeve 101, a body 102, two side force sensors 103, a support shaft 105, a support sleeve 106, front and rear force sensors 107, an oil-free bearing 1011, a two-side force sensor fixing plate 1012, and a centering and guiding assembly. The function of the gooseneck reversing mechanism 1 is to change the direction of the coiled tubing 9 and transmit the force condition between it and the coiled tubing 9 detected in real time by the two side force sensors 103 and the front and rear force sensors 107 to the detection and control terminal.

[0072] The coiled tubing centering sleeve 101 is arranged along the semi-circular arc of the body 102. The number of the coiled tubing centering sleeves 101 is ≥3. The coiled tubing centering sleeve 101 is used to center the coiled tubing 9 to prevent the coiled tubing 9 from detaching from the body 102. The radial length of the coiled tubing centering sleeve 101 gradually increases from the inner end to the outer end, so that a large circular arc can be formed when the coiled tubing 9 passes through its top. The main purpose is to increase the bending diameter of the coiled tubing 9 as much as possible (this large circular arc is at least more than 1.5 times the minimum bending diameter of the coiled tubing); the function of the body 102 is to smoothly change the direction of the moving end of the coiled tubing 9, and at least 5 centering and guiding assemblies are arranged on the body 102.

[0073] The straightening and guiding assembly includes a straightening and guiding block 104, a straightening and guiding block bearing limit cover 108, a straightening and guiding block shaft 109, and a straightening and guiding block bearing 1010. The straightening and guiding block shaft 109 is rotatably connected to the straightening and guiding block bearing limit cover 108 provided on the body 102 through the straightening and guiding block bearing 1010. The straightening and guiding block 104 is fixedly connected to the outside of the straightening and guiding block shaft 109, and arc-shaped grooves for mating with the arc surface of the coiled tubing 9 are provided on all four surfaces of the straightening and guiding block 104. The straightening and guiding block 104 can form a surface contact with the coiled tubing 9, aiming to minimize the stress concentration points on the coiled tubing 9 beyond its limit during the direction-changing process. The coiled tubing straightening sleeve 101 distributed at the inner end of the body 102 is coaxial with the coiled tubing 9 section clamped between the two sets of semi-open chain clamping blocks 208 of the storage and injection mechanism 2.

[0074] A support shaft 105 is connected to the body 102. Both ends of the support shaft 105 are rotatably connected to the support sleeve 106 through oil-free bearings 1011. The upper and lower surfaces of the two side force sensors 103 are fixedly connected to the support sleeve 106 and the two side force sensor fixing plates 1012 respectively. The body 102 can rotate by 0 - ±5° around the support shaft 105. The two side force sensors 103 bear all the weight of the gooseneck commutation mechanism 1 and the downward pulling force from the coiled tubing 9, and are used to sense the stress state of this section of the coiled tubing 9 on both sides of the device in real time, so as to judge whether the coiled tubing is under too much stress or non-vertically platform-loaded, providing a basis for the precise control of the device.

[0075] The upper surfaces of the front and rear force sensors 107 are fixedly connected to the front and rear of the body 102 respectively. The front and rear force sensors 107 are assembled with the slewing support mechanism 3 to form a variable clearance fit, and the clearance size is determined according to the rotation angle of the body 102 relative to the support shaft 105, and is used to sense the magnitude of the pulling force on this section of the coiled tubing 9 in real time, providing a basis for the precise control of the device.

[0076] The storage and injection mechanism 2 includes a first storage and injection component and a second storage and injection component. The first storage and injection component and the second storage and injection component are arranged facing each other to clamp the coiled tubing 9 and make it move axially. The second storage and injection component has the same structure as the first storage and injection component. The function of the storage and injection mechanism 2 is to clamp the coiled tubing 9 and be able to push and pull the coiled tubing 9 axially, ensuring that the moving end of the coiled tubing 9 can smoothly enter or move away from the sleeve-type large-capacity storage tube mechanism 8.

[0077] The first injection and storage component includes a clamping motor bracket 201, a clamping electric linear push rod support seat 202, a clamping force sensor 203, a clamping electric linear push rod 204, an injection and storage power support frame 205, an injection and storage power motor 206, an injection and storage driving sprocket 207, an injection and storage semi-open chain type clamping block group 208, a clamping electric linear push rod connecting seat 209, an injection and storage power support frame limit sliding bearing 2010, an injection and storage power support frame pressure-bearing sliding bearing 2011, an injection and storage driven sprocket 2012, a force adjustment spring group 2013, an injection and storage semi-open chain type clamping block slideway 2014, and a slewing support mechanism interface 2015;

The top of the clamping force sensor 203 is fixedly connected with a clamping electric linear push rod support seat 202. The clamping electric linear push rod support seat 202 is pin-connected to the main body of the clamping electric linear push rod 204. The extending end of the clamping electric linear push rod 204 is fixedly connected to the clamping electric linear push rod connecting seat 209. The function of the pin connection between the clamping electric linear push rod support seat 202 and the main body of the clamping electric linear push rod 204 is to enable the extending end of the clamping electric linear push rod 204 to finely adjust up and down within the gap generated when the injection and storage power support frame 205 slides back and forth on the clamping slideway 3015 of the injection and storage mechanism.

As it continuously enters, after entering the second transition tube 807 for half a circle to three-quarters of a circle, the moving end of the coiled tube will gradually contact the bottom surface of the second transition tube 807. Then, the moving end of the coiled tube reaches the second transition tube coiled tube outlet inside the second transition tube 807. The bottom end of the second transition tube coiled tube outlet is at the same height as the bottom surface of the second transition tube 807. The moving end of the coiled tube will naturally enter the bottom surface of the third storage tube 808 from the second transition tube coiled tube outlet, start the first layer of storage, and realize spiral ascending layer by layer;

[0106] The coiled tubing fixing mechanism 809 includes a split pin 80901, a base 80902, a pin shaft 80903, a lower coiled tubing clamp 80904 and an upper coiled tubing clamp 80905. The base 80902 is fixed on the radial stiffener 802. The pin shaft 80903 is rotationally limited within the base 80902 by the split pin 80901. The upper end of the pin shaft 80903 is hinged with the lower coiled tubing clamp 80904. The upper end of the lower coiled tubing clamp 80904 is bolted with the upper coiled tubing clamp 80905 that can clamp the fixed end of the coiled tubing. The trolley traveling chain 8012 is fixedly connected to the outer side of the inner guide rail 8013 of the traction electric control trolley to form a closed loop; the trolley traveling sprocket 707 is meshed with the trolley traveling chain 8012. The lower coiled tubing clamp 80904 and the upper coiled tubing clamp 80905 can clamp the fixed end of the coiled tubing and can rotate in the horizontal direction and at a certain angle with the horizontal plane; wherein the split pin 80901 prevents the pin shaft 80903 from being pulled out of the lower coiled tubing clamp 80904;

[0107] The hoisting electric hoist 10 is connected to the hoisting electric hoist interface 3018 and is used to hoist fittings and the like.

[0108] Furthermore, the coiled tubing 9 is a continuous tube. When it is stored in the sleeve-type large-capacity tubing storage mechanism 8, it can be divided into an inner tube coiled tubing 901, a coiled tubing inlet section 902, an inner tube coiled tubing outlet to a transition inner tube section 903, a coiled tubing transition inner tube section 904, a coiled tubing transition inner tube to a tubing storage second tube section 905, a coiled tubing tubing storage second tube section 906, a tubing storage second tube section to a transition second tube section 907, a coiled tubing transition second tube section 908, a coiled tubing transition second tube to a tubing storage third tube section 909 and a coiled tubing tubing storage third tube section 9010; the names of different sections of the coiled tubing 9 should be determined according to the number of tubing storage cylinders;

[0109] The working principle and usage process of the present invention:

[0110] The cooperation and relative movement relationship between the gooseneck reversing mechanism 1 and the coiled tubing 9 is that the moving end of the coiled tubing 9 enters upward through the inner end of the main body 102 via the storage and injection mechanism 2 and abuts against the centralizing and guiding block 104. Under the action of an external bending force, it sequentially contacts and elastically deforms with the first few centralizing and guiding blocks 104 arranged on the main body 102, so that the moving end of the coiled tubing smoothly enters into the coiled tubing centralizing sleeve 101 in sequence and finally passes through the coiled tubing centralizing sleeve 101 arranged at the outermost end of the main body 102, completing the change of the coiled tubing 9 from bottom-up to top-down. Subsequently, under the drive of the storage and injection mechanism 2, the coiled tubing 9 is gradually transported from the outer end to the inner end of the main body 102 or transported in the reverse direction;

[0111] The storage and injection mechanism uses two sets of clamping electric linear push rods 204 to synchronously push out and drive the injection and storage power assembly to close towards the center. The central section of the two sets of semi-open chain clamping blocks 208 of the storage and injection mechanism clamps the 9th section of the continuous pipe passing through. Then, the storage and injection power motor 206 drives the storage and injection semi-open chain clamping blocks 208 on the storage and injection driving sprocket 207 and the storage and injection driven sprocket 2012 to move in a cycle. Under the action of sufficient friction, the continuous pipe moves upward or downward and is linked with the storage and guiding mechanism 5, the automatic alignment mechanism 6 of the pipe sleeve, and the traction electric control trolley 7, thereby realizing the storage and injection action of the continuous pipe. At the same time, the mechanism uses the clamping electric linear push rod 204 to synchronously retract and pull the injection and storage power assembly away from the center by a certain distance. The central section of the two sets of semi-open chain clamping blocks 208 of the storage and injection mechanism releases the continuous pipe section passing through and forms a large space, mainly to make enough space for tools or instruments with a larger diameter than the continuous pipe.

[0112] When the auxiliary clamping lifting mechanism 4 lifts, first, the clamping lifting mechanism 402 is in the clamping state, the clamping mechanism 401 is in the loosening state, and the clamping lifting mechanism 402 is driven by the lifting motor 405 to rise upward to the upper position of the lifting screw 403 through the synchronous transmission mechanism 404 and the lifting screw 403. Then, the clamping mechanism 401 is in the clamping state, the clamping lifting mechanism 402 is in the loosening state, and the clamping lifting mechanism 402 is driven by the lifting motor 405 to descend to the lower position of the lifting screw 403 through the synchronous transmission mechanism 404 and the lifting screw 403. Repeating the above two actions can realize the lifting of tools or instruments with a larger diameter than the continuous pipe. When descending, first, the clamping lifting mechanism 402 is in the clamping state, the clamping mechanism 401 is in the loosening state, and the clamping lifting mechanism 402 is driven by the lifting motor 405 to descend to the lower position of the lifting screw 403 through the synchronous transmission mechanism 404 and the lifting screw 403. Then, the clamping mechanism 401 is in the clamping state, the clamping lifting mechanism 402 is in the loosening state, and the clamping lifting mechanism 402 is driven by the lifting motor 405 to rise to the upper position of the lifting screw 403 through the synchronous transmission mechanism 404 and the lifting screw 403. Repeating the above two actions can realize the descent of tools or instruments with a larger diameter than the continuous pipe.

[0113] The storage and guiding mechanism 5 clamps the continuous pipe section passing through at the central section of the two sets of guiding semi-open chain clamping blocks 504. Then, the guiding power motor 508 drives the guiding semi-open chain clamping blocks 504 on the guiding driving sprocket 510 and the guiding driven sprocket 511 to move in a cycle. Under the action of sufficient friction, the continuous pipe moves upward or downward and is linked with the storage and injection mechanism 2, the automatic alignment mechanism 6 of the pipe sleeve, and the traction electric control trolley 7, thereby realizing the storage and guiding action of the continuous pipe 9.

[0114] Driven by the alignment power motor 603, the pipe storage sleeve automatic alignment mechanism 6 drives the alignment walking lead screw 609 to rotate through the alignment synchronous transmission mechanism 602. Then, the alignment bracket 606 moves axially forward and backward along the alignment walking lead screw 609. When the alignment bracket 606 moves away from the slewing support mechanism interface 6011 and stops when the alignment proximity sensor 607 contacts or senses the alignment proximity limit mechanism 608, it indicates that the distal limit position has been reached. When the alignment bracket 606 moves closer to the slewing support mechanism interface 6011 and stops when the alignment proximity sensor 607 contacts or senses the alignment proximity limit mechanism 608, it indicates that the proximal limit position has been reached;

[0115] The trolley walking power motor 704 drives the trolley walking sprocket 707 to rotate. The trolley walking sprocket 707 is engaged with the trolley walking chain 8012 by sprocket and chain. The trolley walking sprocket 707 will rotate both by itself and drive the traction electric control trolley 7 to revolve. By controlling the forward or reverse rotation of the trolley walking power motor 704, the forward revolution and reverse revolution of the traction electric control trolley 7 can be realized.

[0116] When taking out the coiled tubing 9 from the sleeve-type large-capacity pipe storage mechanism 8, first, the free end of the coiled tubing 9 inside the outermost pipe storage cylinder passes through the storage and guiding mechanism 5. After being clamped by the storage and guiding mechanism 5, it is manually guided to the gooseneck reversing mechanism 1, extends to the inside of the storage and injection mechanism 2 after being reversed by the gooseneck reversing mechanism 1, and finally the free end of the coiled tubing 9 is conveyed to the lower end of the target ground;

[0117] When taking out the coiled tubing 9 from the sleeve-type large-capacity pipe storage mechanism 8, first, the traction electric control trolley 7 reciprocates along the sleeve-type large-capacity pipe storage mechanism 8. When the traction electric control trolley 7 is moving, the storage and guiding mechanism 5 continuously conveys the coiled tubing 9 to the gooseneck reversing mechanism 1 by relying on friction, and the storage and injection mechanism 2 continuously conveys the coiled tubing 9 to the lower end of the target ground by relying on friction; when the coiled tubing 9 inside the outermost pipe storage cylinder is taken out, the control terminal controls the pipe storage sleeve automatic alignment mechanism 6 to drive the storage and guiding mechanism 5 to move a certain distance radially inward. At this time, the coiled tubing 9 inside the transition cylinder is taken out. When the coiled tubing 9 inside the transition cylinder is taken out, the control terminal controls the pipe storage sleeve automatic alignment mechanism 6 to drive the storage and guiding mechanism 5 to move a certain distance radially inward again, and continue to repeat the above actions until the coiled tubing 9 of the required length is taken out. The work of storing the coiled tubing 9 into the sleeve-type large-capacity pipe storage mechanism 8 is opposite to the above working process.
