Description

Technical Field

[0001] The invention relates to the technical field of pressure testing, and in particular to a rotary guide hydraulic testing system. Background Art

[0002] The rotary steerable drilling technology is a technology that performs steerable drilling under the condition of full rotation of the drill string. A controllable bias stabilizer or a rotary steerable tool that can control the lateral force (steerage force) of the drill bit is installed above the drill bit, and is equipped with a complete rotary steerable drilling control system to regulate the trajectory of the wellbore when the drill string is rotating during drilling.

[0003] At present, rotary steerable tools have become the key technology restricting my country's deep oil and gas exploitation and shale gas exploitation and other technical fields. Among them, the hydraulic control system of the rotary steerable tool is the core mechanism of the rotary steerable tool. The control accuracy and reliability of the hydraulic control system directly determine the performance and reliability of the rotary steerable tool. In order to promote the rapid development of rotary steerable tools, there is an urgent need for a test device for the hydraulic control system of the rotary steerable tool.

[0004] The patent with publication number CN109854569A discloses a test device for the hydraulic control system of a rotary guide tool. This application can test the performance indicators of the hydraulic control system as a whole. The test results are close to the actual working conditions, accurate and reliable, and have a simple structure, easy use, time-saving and labor-saving, and high testing efficiency, providing a testing means for the real market application of the hydraulic control system.

[0005] However, the above prior art has the following technical defects: Since the hydraulic control system is installed in the rotary steering tool, when the drill bit turns, it will also drive the rotary steering tool to tilt, causing the hydraulic control system to tilt. However, this device only detects the output pressure of the hydraulic control system in a horizontal state, and does not detect the output pressure of the hydraulic control system in a tilted state. The test of the hydraulic control system is relatively simple, and defective products may pass through, reducing the product qualification rate.

[0006] Since hydraulic oil is adhesive, some of it will adhere to the hydraulic control system. When removing it, it is not convenient for the staff to remove it from the test cylinder assembly because the surface of the hydraulic control system contains hydraulic oil, which will cause difficulties in removing the hydraulic control system. In addition, hydraulic oil may drip into the workshop during the removal process, causing pollution to the workshop.

[0007] In summary, the prior art still has room for improvement in testing hydraulic control systems and reducing the difficulty of removing the hydraulic control systems from the test cylinder. Therefore, it is necessary to develop a device that can tilt and test the hydraulic control system and clean the hydraulic control system in the cylinder. Summary of the invention

[0008] To solve the above problems, the present application provides a rotary steering hydraulic test system, adopting the following technical solutions: It includes a test cylinder assembly, and a cross-shaped four-way component is installed at the pressure measuring port of the test cylinder assembly.

[0009] An inclination mechanism is arranged on the side of the test cylinder assembly. The inclination mechanism includes two symmetrically arranged vertical plates. On one side of the vertical plate, there is a fixed seat connected to the test cylinder assembly. Two deflection rods are rotatably installed in the cavity of the fixed seat. A set of strip-shaped grooves are opened at both ends of the deflection rod. Two corresponding sliders are slidably arranged in each group of two strip-shaped grooves. The ends of two corresponding sliders are jointly installed with a U-shaped part. A moving block is jointly installed with the middle two U-shaped parts.

[0011] Preferably, a U-shaped seat connected to it is slidably arranged on the side of the deflection rack, and the sliding direction of the U-shaped seat is perpendicular to the sliding direction of the deflection rack.

[0012] Preferably, a storage mechanism is arranged on one side of the inclination mechanism, and the storage mechanism includes a storage box.

[0013] Preferably, two partition plates are symmetrically installed inside the storage box. The two partition plates divide the inner cavity of the storage box into a water cavity, an oil cavity, and a waste liquid cavity in sequence from front to back.

[0014] Preferably, two dispatching seats are symmetrically installed on the upper side of the storage box. A baffle plate adapted to it is slidably arranged in the cavity of the dispatching seat, and a round rod is installed on the side of the baffle plate.

[0015] Preferably, a first bidirectional screw is rotatably installed between the two dispatching seats on the upper side of the storage box, and first thread seats are arranged on both threads of the first bidirectional screw.

[0016] Preferably, the end of the round rod extends outside the dispatching seat and is installed with a mounting plate. Connecting rods are rotatably installed on both sides of the first thread seat, and the ends of the connecting rods are rotatably connected to the mounting plate on the same side.

[0017] Preferably, a rotating gear is installed at one end of the first bidirectional screw, and a rotating rack meshing with it and connected to the deflection rack on the same side is arranged on the side of the rotating gear.

[0018] Preferably, the oil filling port of the test cylinder assembly is equipped with an input pipe connected to one scheduling seat, and the oil outlet of the test cylinder assembly is equipped with an output pipe connected to another scheduling seat.

[0019] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present invention can tilt the test cylinder assembly at various angles by cooperating with the base mechanism and the tilting mechanism, and then the device can detect the output pressure of the hydraulic control system in the tilted state, so that the detection of the device is no longer single, the detection effect is improved, and defective products are prevented from passing through, and the effect of the finished product is improved. At the same time, when the tilting mechanism is not rotating, the test cylinder assembly is fixed by inserting a pin into the socket, and the deflection rack and the deflection gear are not engaged, so as to avoid the weight of the test cylinder acting on the meshing teeth of the deflection rack and the deflection gear for a long time, thereby damaging them, and extending the service life of the device.

[0020] 2. The present invention cooperates with the tilting mechanism and the storage mechanism, and utilizes the cylinder in the tilting mechanism to provide power for the rotation of the first bidirectional screw in the storage mechanism, so that the mechanism in the storage mechanism changes and the water pipe port is opened, so that a cleaning agent can be sent into the test cylinder assembly, and the cleaning agent is used in conjunction with the operation of the hydraulic test system to clean the inside and remove the residual hydraulic oil, thereby making it easy to remove the hydraulic control system, and also convenient for its transportation and subsequent installation, and protecting the environment in the workshop. At the same time, the storage mechanism conversion power comes from the base mechanism and the tilting mechanism, and there is no need to add additional power electrical appliances, so that the storage mechanism structure is simpler, the manufacturing cost is low, it is not easy to be damaged, and the service life is long.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1 - Fig.14 Embodiments of the present invention are described in detail.

[0038] The embodiment of the present application discloses a rotary guide hydraulic testing system, which can tilt the test cylinder assembly at various angles through the cooperation of a base mechanism and a tilting mechanism. The device can then detect the output pressure of the hydraulic control system in a tilted state, so that the device's detection is no longer single, thereby improving the detection effect, preventing defective products from passing through, and improving the effect of the finished product.

[0039] Embodiment 1: like Figure 1 and Figure 2 As shown, it includes a test cylinder assembly 1, a cross-shaped four-way component 9 is installed at the pressure measuring port of the test cylinder assembly 1, and the ports of the four-way component 9 are respectively installed with a pressure detection component 10 and a pressure gauge 11. The hydraulic control system (including a motor component, a plunger pump component and a control valve component) is installed in the test cylinder assembly 1, and the pressure detection component 10 and the pressure gauge 11 detect the output pressure of the hydraulic control system.

[0040] like Figure 1 and Figure 3 As shown, a base mechanism 4 is arranged below the test tube assembly 1, and the base mechanism 4 includes a bottom plate 401, and two movable grooves 402 are symmetrically opened on the upper side of the bottom plate 401, in which a second bidirectional screw 403 is rotatably installed in one of the movable grooves 402, and a limiting rod 406 is installed in the other movable groove 402, and a driving motor 404 whose driving end is fixedly connected to the end of the second bidirectional screw 403 is installed on the side of the bottom plate 401, and the bottom plate 401 can support other mechanisms in the device, and the driving motor 404 is energized to make it run, and the two driving motors 404 drive the second bidirectional screw 403 connected thereto to rotate.

[0041] like Figure 3 As shown, the two threads of the second bidirectional screw 403 are each provided with a second threaded seat 405 which is slidably connected to the movable groove 402, and the limiting rod 406 is slidably installed with a corresponding limiting block 407 on one side of each second threaded seat 405, and when the driving motor 404 rotates forward, the two second threaded seats 405 thereon can be driven away from each other, and when the driving motor 404 rotates reversely, the two second threaded seats 405 thereon can be driven toward each other.

[0042] like Figure 1 and Figure 4As shown, a tilting mechanism 2 is provided on the side of the test cylinder assembly 1, and the tilting mechanism 2 includes two vertical plates 201 which are symmetrically arranged and fixedly connected to the bottom plate 401 at the lower end. A fixing seat 202 connected to the test cylinder assembly 1 is provided on one side of the vertical plate 201, and the test cylinder assembly 1 is installed on the vertical plate 201 using the two fixing seats 202.

[0043] like Figure 5 and Figure 6 As shown, two deflection rods 205 are rotatably installed in the cavity of the fixed seat 202, and a group of strip grooves 207 are opened at both ends of the deflection rods 205. Two corresponding sliders 208 are slidably arranged in each group of two strip grooves 207. The ends of the two corresponding sliders 208 are jointly installed with a C-shaped piece 209, and the two middle C-shaped pieces 209 are jointly installed with a moving block 206. When the moving block 206 moves, it will drive the two deflection rods 205 to deflect around its rotating connection point through the corresponding C-shaped piece 209 and the slider 208, thereby driving the other two C-shaped pieces 209 to move.

[0044] like Figure 4 and Figure 5 As shown, an annular seat 203 is installed on the side of the vertical plate 201. The surface of the annular seat 203 is circular and has a plurality of evenly distributed pin holes 204. The sides of the two U-shaped members 209 are installed with latches 210 extending into the two pin holes 204. The latches 210 are inserted into the pin holes 204, and the test cylinder assembly 1 is fixed on the annular seat 203 through the two fixing seats 202. When the two U-shaped members 209 move, the latches 210 will also be driven to move.

[0045] like Figure 5 As shown, a rotating tube 211 penetrating the vertical plate 201 on the same side is installed at the center of the side of the fixing seat 202, and a deflection gear 212 is installed at the end of the rotating tube 211. A deflection rack 214 is provided on one side of the deflection gear 212. After the deflection rack 214 is moved horizontally to engage with the deflection gear 212, the deflection rack 214 is moved longitudinally to drive the deflection gear 212 to rotate, thereby driving the test cylinder assembly 1 to rotate and adjust its tilt angle.

[0046] like Figure 5 and Figure 6As shown, a hollow groove is provided on the side of the deflection rack 214, in which a mounting slide bar 215 is installed, on which a mounting slider 216 is slidably provided, and on the side of the mounting slider 216 a connecting plate 217 is installed, and on the side of the moving block 206 a shaft rod 213 is installed which passes through the rotating tube 211 and is rotatably connected to the connecting plate 217. When the deflection rack 214 is driven to move laterally, the shaft rod 213 is driven to move by the cooperation of the mounting slide bar 215, the mounting slider 216 and the connecting plate 217, and the moving shaft rod 213 drives the moving block 206 to move, and when the deflection rack 214 moves longitudinally, the mounting slider 216 will not be driven to move.

[0047] like Figure 4 and Figure 5 As shown, each second threaded seat 405 and the corresponding limit block 407 are jointly installed with a C-shaped seat 221 on the upper side, and a group of movable slide bars 218 are installed on the inner side of the C-shaped seat 221. Two movable slide bars 219 fixedly connected to the deflection rack 214 on the same side are slidably arranged on the two movable slide bars 218. A cylinder 220 with an end fixedly connected to one of the movable slide bars 219 is installed on the inner side of the C-shaped seat 221. When the cylinder 220 is extended, it drives the movable slide bar 219 to slide on the movable slide bar 218, and the sliding movable slide bar 219 drives the deflection rack 214 to move longitudinally.

[0048] In summary, when adjusting the tilt angle of the test tube assembly 1, the driving motor 404 rotates the second bidirectional screw 403, thereby driving the two second threaded seats 405 to separate, driving the C-shaped seats 221 to move away from each other, and allowing the two deflection racks 214 to move laterally until they are engaged with the deflection gear 212 on the same side. At the same time, the deflection rack 214 that moves laterally drives the shaft 213 to move through the installation slide bar 215, the installation slider 216 and the connecting plate 217. The moving shaft 213 drives the moving block 206 to move, and drives the two deflection rods 205 to deflect around the rotating connection through the corresponding C-shaped piece 209 and the slider 208, and at the same time drives the other two C-shaped pieces 209 to move, so that the latch 210 is disengaged from the pin hole 204, thereby releasing the fixing. After the fixed seat 202 is fixed, the two cylinders 220 extend to drive the two deflection racks 214 to move horizontally, drive the two deflection gears 212 to rotate, and drive the test cylinder assembly 1 to rotate, so as to adjust the deflection angle of the test cylinder assembly 1. After reaching the predetermined test angle, the staff fine-tunes the angle of the test cylinder assembly 1 to align the four latches 210 with the nearest four pin holes 204, and then the driving motor 404 drives the second bidirectional screw 403 to reverse and move the two U-shaped seats 221 closer to each other, thereby driving the two moving blocks 206 closer to each other, and allowing the deflection rod 205 to reverse and deflect so that each latch 210 is inserted into the aligned pin hole 204, thereby fixing the test cylinder assembly 1 and releasing the meshing of the deflection rack 214 with the corresponding deflection gear 212.

[0049] like Figure 7-Figure 9 As shown, a storage mechanism 3 is provided on one side of the tilting mechanism 2, and the storage mechanism 3 includes a storage box 301. Two partitions 302 are symmetrically installed inside the storage box 301. The two partitions 302 divide the inner cavity of the storage box 301 into a water chamber, an oil chamber and a waste liquid chamber in front and back order. The water chamber is used to store hydraulic oil cleaning agent, the oil chamber is used to store hydraulic oil, and the waste liquid chamber is used to store waste liquid generated by cleaning the hydraulic oil.

[0050] like Fig. 9 and Fig.10 As shown, two scheduling seats 307 are symmetrically installed on the upper side of the storage box 301, and a baffle 308 matching it is slidably arranged in the cavity of the scheduling seat 307. A round rod 309 is installed on the side of the baffle 308. When the round rod 309 moves, it can drive the baffle 308 to move, and the moving baffle 308 can push the liquid in the cavity to move.

[0051] like Figure 8 As shown, a first bidirectional screw 303 is rotatably installed on the upper side of the storage box 301 between two scheduling seats 307, and first threaded seats 304 are provided on both threads of the first bidirectional screw 303. The end of the round rod 309 extends to the outside of the scheduling seat 307 and is installed with a mounting plate 310. Connecting rods 319 are rotatably installed on both sides of the first threaded seat 304, and the ends of the connecting rods 319 are rotatably connected to the mounting plate 310 on the same side. When the first bidirectional screw 303 rotates, it drives the two first threaded seats 304 to approach each other, and pulls the two mounting plates 310 to approach each other through four connecting rods 319, while driving the two round rods 309 to move.

[0052] like Fig.11 and Fig.12 As shown, a group of cross bars 14 are installed on the rear side of the storage box 301, and a slide 15 is slidably arranged on the two cross bars 14. A rotating gear 305 is installed at one end of the first bidirectional screw 303, and a rotating rack 306 meshing with the rotating gear 305 is arranged on the upper side of the slide 15. When the slide 15 moves, it drives the rotating rack 306 to move, and the moving rotating rack 306 drives the meshing rotating gear 305 to rotate, thereby driving the first bidirectional screw 303 to rotate.

[0053] like Fig. 9 and Fig.10As shown, the oil filling port of the test cylinder assembly 1 is installed with an input pipe 7 connected to a dispatching seat 307, and the dispatching seat 307 connected to the input pipe 7 is respectively installed with a water pipe 311 and an oil pipe 312 on both sides. The lower end of the water pipe 311 extends to the bottom of the water cavity and is installed with a water pump 315, and the lower end of the oil pipe 312 extends to the bottom of the oil cavity and is installed with an oil pump 316. During testing, the running oil pump 316 delivers the hydraulic oil in the oil cavity into the test cylinder assembly 1 through the oil pipe 312, the dispatching seat 307 and the input pipe 7. During cleaning, the running water pump 315 delivers the hydraulic oil cleaning agent in the water cavity into the test cylinder assembly 1 through the above-mentioned pipelines.

[0054] like Fig. 9 and Fig.10 As shown, the oil outlet of the test cylinder assembly 1 is installed with an output pipe 8 connected with another dispatching seat 307, and the dispatching seat 307 connected with the output pipe 8 is respectively installed with a return oil pipe 313 and a return sewage pipe 314 on both sides. The return oil pipe 313 extends into the oil chamber, and the return sewage pipe 314 extends into the waste liquid chamber. The hydraulic oil after detection returns to the oil chamber through the output pipe 8, another dispatching seat 307 and the return oil pipe 313, and the waste liquid after cleaning returns to the waste liquid chamber through the output pipe 8, the dispatching seat 307 and the return sewage pipe 314.

[0055] like Figure 8 and Fig. 9 As shown, a faucet 317 connected to the waste liquid chamber is installed on the side of the storage box 301 near the bottom, and two liquid inlet pipes 318 connected to the water chamber and the oil chamber respectively are installed on the front side of the storage box 301 near the top. By opening the faucet 317, the waste liquid can be discharged from the faucet 317, and cleaning agent and hydraulic oil can be added to the water chamber and the oil chamber respectively through the two liquid inlet pipes 318.

[0056] like Fig.12 As shown, a slot 16 is provided on the side of the slide 15, and an L-shaped plate 12 is installed on the side of a movable slider 219 on the same side as the slide 15. A block 13 adapted to the slot 16 is installed on the side of the L-shaped plate 12. When the block 13 on the L-shaped plate 12 is engaged with the slot 16, the movable movable slider 219 can drive the L-shaped plate 12 to move, and the movable L-shaped plate 12 drives the slide 15 to move through the block 13 and the slot 16.

[0057] In summary, during testing, the running oil pump 316 delivers the hydraulic oil in the oil chamber into the test cylinder assembly 1 through the oil pipe 312, the dispatching seat 307 and the input pipe 7, and then the oil returns to the oil chamber through the output pipe 8, another dispatching seat 307 and the return oil pipe 313. When the test cylinder assembly 1 needs to be cleaned, the driving motor 404 will reverse the second bidirectional screw 403, and the U-shaped seat 221 will drive the two sets of movable sliders 219 to approach each other. The movement of the movable slider 219 causes the card block 13 to be inserted into the card slot 16. At this time, the cylinder 220 on the same side of the L-shaped plate 12 extends, and further drives the slide 15 to move through the L-shaped plate 12. The moving slide 15 drives the rotating rack 306 to move, and drives the first bidirectional screw 303 to rotate through the meshing rotating gear 305, driving the two first threaded seats 304 to approach each other, and drives the two mounting plates 310 to approach each other through the four connecting rods 319, and then drives the two baffles 308 to approach each other through the two round rods 309. The hydraulic oil in the cavities of the two dispatching seats 307 is pressed back into the oil cavity through the oil pipe 312 and the return oil pipe 313. At the same time, the ports of the oil pipe 312 and the return oil pipe 313 are closed, and the ports of the water pipe 311 and the return sewage pipe 314 are opened. Then the running water pump 315 extracts the hydraulic oil cleaning agent in the water cavity and sends it into the test cylinder assembly 1 through the water pipe 311, the dispatching seat 307 and the input pipe 7 for cleaning. Then the cleaning waste liquid returns to the waste liquid cavity through the output pipe 8, the other dispatching seat 307 and the return sewage pipe 314.

[0058] Embodiment 2: like Figure 7 and Fig.13 As shown, on the basis of the first embodiment, a recovery mechanism 5 is further included, the recovery mechanism 5 includes a U-shaped frame 501 installed on the upper side of the storage box 301, and the input pipe 7 and the output pipe 8 are both provided with a cylinder 502 fixedly connected to the U-shaped frame 501 and placed horizontally, and a group of pistons 503 are arranged in the cylinder 502, and a group of mutually aligned through holes 508 are opened on the side of each group of two pistons 503. When the two groups of through holes 508 on the two pistons 503 are aligned, liquid can pass through the through holes 508, and when the two groups of through holes 508 are aligned, liquid cannot pass through.

[0059] like Fig.13 and Fig.14 As shown, a round tube 505 is installed at the center of the side of one of the pistons 503 in the group, the end of the round tube 505 extends to the outside of the cylinder 502 and is installed with a mouth-shaped frame 504, and an electric push rod 509 with an end fixedly connected to it is installed on the upper side of the U-shaped frame 501 on one side of each mouth-shaped frame 504. The extended electric push rod 509 drives the piston 503 connected to it to move through the mouth-shaped frame 504 and the round tube 505.

[0060] like Fig.13 and Fig.14As shown, a rotating rod 506 extending into the circular tube 505 is installed at the center of the side of another piston 503 in the group, and a rotating motor 507 whose driving end is fixedly connected to the rotating rod 506 on the same side is installed on the inner side of the mouth-shaped frame 504. The running rotating motor 507 can drive the rotating rod 506 to rotate, and the rotating rotating rod 506 drives the piston 503 connected thereto to rotate.

[0061] In summary, before cleaning, the rotary motor 507 drives the rotary rod 506 to rotate the piston 503 by ninety degrees, causing the two sets of through holes 508 to be misaligned. Subsequently, the electric push rod 509 extends, pushing the piston 503 to move, pressing the oil in the cylinder 502 into the dispatching seat 307, and at the same time withdrawing the hydraulic oil in the input pipe 7 and the output pipe 8. Then, the rotary motor 507 is reversed to reset the piston 503 and align the through holes 508. The electric push rod 509 shortens, the piston 503 recovers, and the rotary motor 507 drives the piston 503 to rotate ninety degrees again, causing the through holes 508 to be misaligned. The electric push rod 509 extends, pressing the oil in the cylinder 502 back into the oil chamber.

[0062] Similarly, before testing, the operation can be repeated to draw back the cleaning agent and waste liquid in the input pipe 7 and the output pipe 8. At this time, one cylinder 502 stores the cleaning agent and the other stores the waste liquid. The cleaning agent is then pressed into the water cavity, and the waste liquid is forced into the waste liquid cavity. The residual oil in the input pipe 7 and the output pipe 8 can be taken out before cleaning, thereby reducing the waste of oil. At the same time, the cleaning agent in the input pipe 7 can be taken out before testing to prevent the hydraulic oil mixed with the cleaning agent from entering the test cylinder assembly 1 and affecting the test results. At the same time, taking out the waste liquid in the output pipe 8 can also prevent the waste liquid mixed with the oil from returning to the oil cavity and contaminating the hydraulic oil.

[0063] The working principle steps of the present invention are as follows: S1. System installation: install the hydraulic control system in the test cylinder assembly 1. Specifically, open the test cylinder assembly 1, properly install the hydraulic control system including the motor assembly, the plunger pump assembly and the control valve assembly inside the test cylinder assembly 1, then close the test cylinder assembly 1, and connect the oil inlet of the test cylinder assembly 1 to the input pipe 7, connect the oil outlet of the test cylinder assembly 1 to the output pipe 8, install the pressure detection assembly 10 and the pressure gauge 11 at the ports of the four-way assembly 9 respectively, and close the other ports.

[0064] S2, system test, inject oil into the test cylinder assembly 1 to let the hydraulic control system run and detect its output pressure. Specifically, the running oil pump 316 sends the hydraulic oil in the oil chamber into the test cylinder assembly 1 through the oil pipe 312, the dispatching seat 307 and the input pipe 7. The hydraulic control system works, and the motor assembly starts the plunger pump assembly to pump the hydraulic oil into the control valve assembly. After the hydraulic oil enters the control valve assembly, a part of it enters the high-pressure area of ​​the control valve assembly, so that the pressure in the high-pressure area increases, and the output pressure of the pressure output port also increases. The pressure gauge 11 and the pressure detection assembly 10 are used to detect the output pressure of the pressure output port, and the remaining part is discharged from the control valve assembly through the throttle valve. After that, the oil returns to the oil chamber through the output pipe 8, another dispatching seat 307 and the return oil pipe 313. The speed of the motor assembly controls the output pressure of the pressure output port. As the speed of the motor assembly increases, the hydraulic oil pumped into the control valve assembly by the plunger pump assembly increases, the pressure in the high-pressure area increases, and the output pressure of the pressure output port increases.

[0065] S3, angle tilting, the test tube assembly 1 is angle tilted and its output pressure is detected. Specifically, after the driving motor 404 is started, the second bidirectional screw 403 is driven to start rotating, and the two second threaded seats 405 are driven to move away from each other, thereby making the two U-shaped seats 221 also separate from each other, so that the two deflection racks 214 can move laterally until they are engaged with the deflection gear 212 on the same side. At the same time, the deflection rack 214 that moves laterally also pushes the moving block 206 to move through the shaft 213. The movement of the moving block 206 drives the two deflection rods 205 to deflect around the rotating connection. This deflection action further drives the movement of the other two U-shaped members 209, so that the two latches 210 are smoothly moved out of the pin hole 204.

[0066] Afterwards, the two cylinders 220 extend to drive the two deflection racks 214 to move horizontally, and drive the test tube assembly 1 to rotate through the deflection gear 212. After reaching the predetermined test angle, the staff fine-tunes the angle of the test tube assembly 1 to align the four pins 210 with the four nearest pin holes 204. Then, the driving motor 404 drives the second bidirectional screw 403 in reverse to move the two U-shaped seats 221 closer to each other, thereby driving the two moving blocks 206 closer to each other, allowing the deflection rod 205 to reverse and deflect so that each pin 210 is stuck in the aligned pin hole 204, thereby fixing the test tube assembly 1 and releasing the meshing of the deflection rack 214 with the corresponding deflection gear 212.

[0067] S4, pressure observation. After each tilt of the test cylinder assembly 1, the staff observes the output pressure on the pressure gauge 11 and the pressure detection component 10. Specifically, after the tilt of the test cylinder assembly 1 is completed, the staff can observe the output pressure of the test cylinder assembly 1 when it is tilted, and then repeat the S3 operation to tilt the test cylinder assembly 1 multiple times and observe its output pressure multiple times. If the pressure reaches the existing index each time, it means that the hydraulic control system is qualified. If the pressure does not reach the existing index, it means that the hydraulic control system is unqualified.

[0068] S5. System cleaning. Clean the inside of the test cylinder assembly 1 and the hydraulic control system. Specifically, the driving motor 404 drives the second bidirectional screw 403 to reverse, and drives the two groups of movable slide blocks 219 to approach each other through the U-shaped seat 221. The movable movable slide block 219 drives the card block 13 to be stuck in the card slot 16. The cylinder 220 on the same side of the L-shaped plate 12 extends to drive the slide seat 15 to move through the L-shaped plate 12. The movable slide seat 15 drives the rotating rack 306 to move, and drives the first bidirectional screw 303 to rotate through the meshing rotating gear 305, drives the two first threaded seats 304 to approach each other, drives the two mounting plates 310 to approach each other through the four connecting rods 319, and then drives the two baffles 308 to approach each other through the two round rods 309, and uses the oil pipe 312 and the return oil pipe 313 to move the two dispatching seats. The hydraulic oil in 307 is pressed back into the oil chamber, and at the same time, the ports of the oil pipe 312 and the return oil pipe 313 are closed, and the ports of the water pipe 311 and the return sewage pipe 314 are opened. Then, the running water pump 315 extracts the hydraulic oil cleaning agent in the water chamber and sends it into the test cylinder assembly 1 through the water pipe 311, the dispatching seat 307 and the input pipe 7. When the cleaning agent flows through the test cylinder assembly 1, the hydraulic control system starts synchronously to promote the flow of the cleaning agent, and uses the cleaning agent to flush the inside of the test cylinder assembly 1 and every corner of the hydraulic control system to clean and take away the residual hydraulic oil. The waste liquid after cleaning passes through the output pipe 8, another dispatching seat 307 and the return sewage pipe 314, and finally flows back to the waste liquid chamber. After the staff observes that the color of the waste liquid in the transparent output pipe 8 is the same as the color of the cleaning agent, it means that the hydraulic oil cleaning is completed, and the water pump 315 is turned off.

[0069] S6. Structural restoration. Take out the hydraulic control system in the test cylinder assembly 1. Specifically, after cleaning, open the test cylinder assembly 1 and take out the cleaned hydraulic control system. If the system passes the inspection, it can be directly assembled into the rotary guide tool for use. If it fails, it needs to be reworked. At the same time, the cylinder 220 on the same side of the storage box 301 is shortened to drive the rotating rack 306 to reverse, and the first bidirectional screw 303 is reversed by the rotating gear 305, so that the two baffles 308 move away from each other, the ports of the water pipe 311 and the sewage return pipe 314 are closed, and the ports of the oil pipe 312 and the oil return pipe 313 are opened, and then the next test can be carried out.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
