Technical Field

[0001] This invention belongs to the field of ballastless track construction technology, and in particular relates to a turnout fine-tuning system and method. Background Technology

[0002] During the fine-tuning of turnouts, the effect of fine-tuning the ballastless track of high-speed railways will directly affect the safety of train operation. Therefore, after the base plate is completed, turnout sleepers and rails need to be installed, and then the rails need to be fine-tuned to meet the design elevation and centerline design requirements.

[0003] However, current rail fine-tuning requires manual adjustment, involving manually turning wrenches and screws, which is inefficient. Furthermore, rail fine-tuning is a large undertaking and quite difficult. How to quickly perform fine-tuning and reduce manpower input is one of the urgent problems to be solved in the construction of turnout fine-tuning systems.

[0004] Therefore, a well-designed and easy-to-operate turnout fine-tuning system is needed to quickly complete the fine-tuning of the turnout's elevation and centerline, reduce manual assistance, save manpower and resources, and improve construction efficiency. Summary of the Invention

The lateral fine adjuster is detachably clamped onto the double-threaded telescopic rod and can drive the double-threaded telescopic rod to rotate so that the double-threaded telescopic rod extends or retracts. The double-threaded telescopic rod is arranged laterally and connected to the rail of the turnout.

The sleeve component includes a transition sleeve, a universal joint, and a bottom sleeve that are connected in transmission to the elevation adjustment power mechanism. An elastic element is provided between the bottom of the transition sleeve and the universal joint.

[0008] In the aforementioned turnout fine-tuning system, a circular ring plate is further provided on the universal joint, the circular ring plate is located below the transition sleeve, and a proximity switch is provided on the top of the circular ring plate, with the detection surface of the proximity switch facing the top of the circular ring plate. The bottom of the transition sleeve is provided with two symmetrically arranged waist-shaped guide holes. An upper pin is inserted into the universal joint and the two waist-shaped guide holes. The upper pin can move up and down along the waist-shaped guide holes. The lower part of the transition sleeve is fitted with a protective sleeve, which covers the waist-shaped guide hole, and the outer side wall of the transition sleeve is fitted with the inner side wall of the protective sleeve.

[0009] In the aforementioned turnout fine-tuning system, the double-threaded telescopic rod is further provided with a central hexagonal portion; The lateral fine-tuning device includes a housing, a lateral power module disposed within the housing, a transmission gear set connected to the lateral power module, and an open gear meshing with the transmission gear set. The open gear is sleeved on the middle outer hexagonal part and can drive the middle outer hexagonal part to rotate, so as to extend and retract the double threaded telescopic rod.

[0010] In the aforementioned turnout fine-tuning system, the transmission gear set is located inside the gear housing, a limiting plate is provided at the bottom of the gear housing, a through limiting hole is provided at the bottom of the limiting plate, the top of the limiting hole is semi-circular, and the center of the semi-circular top of the limiting hole coincides with the center of the first internal hexagonal hole of the open gear. It also includes a bracket for mounting the double-threaded telescopic rod in the lateral fine adjuster, the bracket being a floor bracket or a U-shaped bracket.

[0011] In the aforementioned turnout fine-tuning system, the tilt detection trolley further includes a long car body, a tilt sensor disposed in the long car body, a connecting slide rail disposed under the extended beam, a sliding guide embedded in the connecting slide rail, and a connecting rod connecting the sliding guide and the long car body. A display screen is disposed on the top surface of the long car body, and moving wheels are disposed at both ends of the long car body.

[0012] In the aforementioned turnout fine-tuning system, the end of the fine-tuning moving vehicle is provided with two external U-shaped seats, two external ear plates are respectively provided on the two extension beams, and internal ear plates are provided on both ends of the crossbeam; The inner ear plate extends into the two outer ear plates, and the two outer ear plates extend into the outer U-shaped seat, and the three are hinged together by a hinge shaft; one of the outer U-shaped seats is provided with an upper waist-shaped hole to accommodate the sliding of the hinge shaft; A telescopic rod is provided between the fine-tuning moving vehicle and the extension beam. The telescopic rod can be an electric push rod, a hydraulic cylinder, or a pneumatic cylinder.

[0013] Meanwhile, a method for fine-tuning the elevation of a turnout is provided, which includes the following steps: Step S1: The fine-tuning mobile car pulls the Amberg rail inspection trolley along the straight track. The first vision camera on the crossbeam captures the QR code image of the turnout sleeper and sends it to the vision controller to obtain the current turnout sleeper number. Step S2: The main controller inside the fine-tuning moving car receives the current turnout sleeper number and obtains the lateral displacement of the elevation screw relative to the elevation adjuster at the current turnout sleeper number from the elevation adjuster and elevation screw phase lateral displacement database. Step S3: Adjust the lateral movement of the elevation adjuster according to the lateral movement of the elevation screw relative to the elevation adjuster on the current turnout sleeper number, and the lateral movement must satisfy step S2; Step S4: The second vision camera at the bottom of the elevation adjuster captures an image of the elevation screw on the current turnout sleeper number. With the center of the second vision camera and the center of the bottom sleeve fixed at the same position, the image is processed by the vision controller to obtain the displacement of the center of the elevation screw relative to the center of the bottom sleeve. Step S5: Based on the displacement of the center of the elevation screw relative to the center of the bottom sleeve, control the elevation adjuster to move continuously so that the center of the elevation screw and the center of the bottom sleeve coincide; and drive the sleeve component to descend through the lifting mechanism so that the bottom sleeve is fitted onto the top of the elevation screw. Step S6: Obtain the elevation error value at the current turnout sleeper number using the Amberg track inspection trolley, and based on the elevation error value at the current turnout sleeper number, finely adjust the elevation screw at the current turnout sleeper number using the elevation adjuster on the straight track, with the adjustment amount being the elevation error value. The elevation of the elevation screw on the side stock is finely adjusted by the elevation adjuster on the side stock until the tilt angle detected by the tilt angle detection trolley on the side stock is zero. Step S7: Repeat step S6 multiple times until the elevation error value at the current turnout sleeper number is less than or equal to ±0.3mm. Then the current turnout sleeper elevation meets the construction design requirements. Step S8: Following the methods of steps S1 to S7, complete the elevation adjustment of the remaining turnout sleepers in sequence.

[0014] Meanwhile, a method for fine-tuning the centerline of a turnout is provided, which includes the following steps: Step A1: The fine-tuning mobile car pulls the Amberg track inspection trolley along the straight track to inspect the turnout sleepers equipped with centerline adjusters, and obtain the centerline error value at each turnout sleeper equipped with a centerline adjuster. Step A2: The rails of the turnout are moved laterally by multiple centerline adjusters installed, and the adjustment amount is the centerline error value. Step A3: Repeat steps A1 and A2 multiple times until the centerline error value is less than ±0.3mm, then the turnout centerline meets the construction design requirements; When multiple centerline adjusters are installed to adjust the lateral movement of the turnout rails, the specific process is as follows: Step A: Connect the EtherCAT port of the PLC controller to the EtherCAT IN port of the first horizontal motor driver using a standard shielded network cable. Connect the remaining horizontal motor drivers in the multiple centerline adjusters in series with standard shielded network cables. The PLC controller is wirelessly connected to the tablet computer via a Wi-Fi communication module. Step B: The tablet computer receives the centerline error value and sends an adjustment command to the PLC controller. The PLC controller receives the adjustment command and sends it to the lateral motor driver using the EtherCAT protocol. The lateral motor driver controls the lateral rotating component to work. The lateral rotating component drives the lateral reducer to rotate. The rotation of the lateral reducer drives the open gear to rotate in sequence through the drive gear and the transition gear. When the open gear is sleeved under the middle outer hexagonal part, it drives the adjusting screw sleeve to rotate, so that the double threaded telescopic rod extends. The double threaded telescopic rod then pushes the turnout rail to move laterally through the rail clamping component. Alternatively, the lateral rotating component can be operated to rotate in the opposite direction, so that the double threaded telescopic rod retracts. The double threaded telescopic rod then pushes the turnout rail to move laterally in the opposite direction through the rail clamping component, and the adjustment amount is the centerline error value.

[0015] Meanwhile, a method for fine-tuning a turnout is provided, which includes the following steps: Step 1: Install multiple centerline adjusters along the outer rails of the straight and side rails; Step 2: Hoist the fine-tuning moving vehicle onto the straight section; Step 3: Place the Amberg track inspection trolley on the straight track and the tilt detection trolley on the side track; connect both the Amberg track inspection trolley and the tilt detection trolley to the fine-tuning moving car. Step 4: Fine-tune the moving car to pull the Amberg track inspection trolley along the straight track to obtain the centerline error value at the turnout sleeper where the centerline adjuster is installed; Step 5: Based on the centerline error value, multiple centerline adjusters automatically adjust the centerline of the turnout using a tablet computer. Step 6: Repeat steps 4 and 5 for the next automatic adjustment until the centerline error is less than ±0.3mm; Step 7: Fine-tune the movement of the mobile car to pull the Amberg track inspection trolley along the straight track to obtain the current elevation error value at the turnout sleeper; Step 8: Fine-tune the moving vehicle control elevation adjuster and fine-tune all elevation screws at the fork bolster until the elevation error is less than ±0.3mm; Step 9: Following the methods in Steps 7 and 8, adjust the next turnout sleeper until the elevation error is less than ±0.3mm; Step 10: Remove all lateral fine adjusters. Turnout fine adjustment is now complete.

[0016] Compared with the prior art, the present invention has the following advantages: 1. This invention has a simple structure, reasonable design, and convenient operation, enabling fine adjustment of turnouts.

[0017] 2. The centerline adjuster used in this invention can be installed along the extension direction of the turnout, and each centerline adjuster is installed along the outer rail of the straight track and the side track, which can realize the adjustment of the turnout centerline, reduce manual intervention, and thus improve the adjustment efficiency.

[0018] 3. The transverse fine adjuster used in this invention is clamped on the telescopic rod, eliminating the need for manual assistance in adjustment and avoiding manual intervention; in addition, the double-threaded telescopic rod is directly connected to the rail, avoiding the complex and labor-intensive operation of welding steel bars.

[0019] 4. The lateral fine-tuning device used in this invention drives the double-threaded telescopic rod to extend, and the double-threaded telescopic rod pushes the rail of the turnout to move laterally through the rail clamping device; when the double-threaded telescopic rod retracts, the double-threaded telescopic rod pushes the rail of the turnout to move laterally in the opposite direction through the rail clamping device, thereby realizing the centerline adjustment of the rail until the construction design requirements are met.

[0020] 5. The present invention sets up a vision camera in the drive box, and the vision camera is pointed towards the turnout sleeper to realize the positioning of the elevation screw, which facilitates accurate installation.

[0021] 6. An elastic element is provided between the bottom of the transition sleeve and the universal joint used in this invention. When the sleeve component moves down, the contracted elastic element ensures that it applies a downward force to the elevation screw, so that the bottom of the elevation screw contacts the steel pad on the base plate. In this way, when the sleeve component drives the elevation screw to rotate, the elevation of the turnout sleeper can be adjusted because the elevation screw is threadedly connected to the turnout sleeper, thus avoiding the bottom of the elevation screw from being suspended and spinning idly.

[0022] 7. The tilt angle detection trolley used in this invention is placed on the side stock. The tilt angle detection trolley and the fine-tuning moving trolley move and stop synchronously. While the Amberg trolley detects the elevation and centerline of the straight stock, the tilt angle sensor detects the tilt angle of the side stock. The side stock is kept horizontal to achieve the same elevation as the straight stock, thereby realizing the automatic adjustment of the side stock elevation.

[0023] 8. The method for fine-tuning turnouts in this invention is simple in steps, easy to implement and operate, and ensures that the elevation and centerline of the turnout meet the design requirements.

[0024] In summary, the present invention is reasonably designed and can quickly complete the fine adjustment of the elevation and centerline of the turnout, reduce manual assistance, save manpower and material resources, and improve construction efficiency.

[0066] In this embodiment, during actual use, the lower part of the cover plate 1008 is provided with an L-shaped seat, and the L-shaped seat is provided with a lower bearing for the bottom of the lead screw 5004 to be rotatably mounted.

[0067] In this embodiment, during actual use, the guide rail of the linear guide is installed on the cover plate 1008, and the length direction of the guide rail is arranged along the height direction of the cover plate 1008. The guide rail slider on the linear guide rail is connected to the first mounting base 1012 so that when the elevation adjustment power mechanism is raised or lowered, the guide rail slider moves up and down along the guide rail synchronously.

[0068] In this embodiment, during actual use, a vertical connecting plate 6001 is provided at the bottom of the first mounting base 1012, the proximity switch 600 is installed at the bottom of the vertical connecting plate 6001, and the annular plate 1014 covers the detection range of the proximity switch 600.

[0069] In this embodiment, it should be noted that when the elastic element is in its natural state, the distance between the detection surface of the proximity switch 600 and the annular plate 1014 is greater than the detection distance of the proximity switch 600, so the proximity switch 600 does not detect the annular plate 1014; if the elastic element is in its contracted state, the annular plate 1014 is close to the proximity switch 600, so the proximity switch 600 detects the annular plate 1014, thereby achieving detection.

[0070] In this embodiment, when the sleeve component moves down and is fitted onto the top of the elevation screw, the sleeve component gradually moves down, the elastic element gradually contracts, and the annular plate 1014 moves closer to the proximity switch 600 until the proximity switch 600 detects the annular plate 1014. Then the sleeve component stops moving down, thereby ensuring that the contracted elastic element exerts a downward force on the elevation screw so that the bottom of the elevation screw contacts the steel pad on the base plate. In this way, when the sleeve component drives the elevation screw to rotate, the elevation adjustment of the turnout sleeper is achieved because the elevation screw and the turnout sleeper are threadedly connected.

[0071] In this embodiment, the protective sleeve 1005 is provided to limit the upper pin 1009, prevent the upper pin 1009 from slipping, and not affect the upper pin 1009 from moving up and down along the waist-shaped guide hole 10033 to adapt to the expansion and contraction of the spring 1004.

[0072] In this embodiment, the bottom surface of the protective sleeve 1005 is attached to the annular plate 1014 to limit the position of the protective sleeve 1005.

[0073] In this embodiment, the top of the transition sleeve 1003 is provided with an upper receiving hole 10031, the output end of the first reducer 1002 extends into the upper receiving hole 10031, and the output end of the first reducer 1002 and the top of the transition sleeve 1003 are connected by a key drive. The bottom of the transition sleeve 1003 is provided with a lower receiving hole 10032, and the spring 1004 is located in the lower receiving hole 10032. The inner diameter of the lower receiving hole 10032 is larger than the inner diameter of the upper receiving hole 10031. The top of the universal joint also extends into the lower receiving hole 10032 so that the annular plate 1014 is arranged to fit against the bottom of the transition sleeve 1003.

[0074] In this embodiment, there are two universal joints, namely the first universal joint 1013 and the second universal joint 1015 from top to bottom. The annular plate 1014 is disposed on the first universal joint 1013. The top of the first universal joint 1013 extends into the lower receiving hole 10032 and is connected to the bottom of the transition sleeve 1003 through the upper pin 1009. The bottom of the second universal joint 1015 is connected to the bottom sleeve 1007.

[0075] In this embodiment, the universal joint can be referenced as the universal joint sleeve of the pneumatic wrench, allowing for flexible adjustment within a certain range.

[0076] In this embodiment, the connection between the first universal joint 1013 and the second universal joint 1015, as well as the connection between the second universal joint 1015 and the bottom sleeve 1007, or the sleeve component, can also be referred to the sleeve component structure and connection relationship in patent CN202110934532.2, "An Intelligent Device and Fastening Method for Fastening Railway Track Fastener Bolts".

[0077] In this embodiment, a rubber sleeve 1006 is added to the outside of the universal joint and the bottom sleeve 1007 to limit the universal joint joint so that the universal joint joint and the bottom sleeve 1007 are aligned.

[0078] In this embodiment, the interior of the bottom sleeve 1007 engages with the top of the elevation screw of the turnout sleeper, so that the rotation of the bottom sleeve 1007 drives the elevation screw to rotate.

[0079] In this embodiment, the strip fill light 700 is set on both sides of the second vision camera 300, and the illumination surface of the strip fill light 700 faces the fork pillow; For the 700 strip fill light, refer to the MV-LLDS-H-250-30-X fill light to provide supplemental lighting for the second vision camera 300. For the camera, refer to the conventional method to ensure that it does not interfere with the shooting operation of the second vision camera 300.

[0080] In this embodiment, there is a gap between the axis of the second vision camera 300 and the axis of the bottom sleeve 1007.

[0081] In this embodiment, the laser rangefinder 400 can refer to the DT35S laser sensor to realize the spacing measurement. When the elevation adjuster is located above the turnout sleeper, the spacing detected by the laser rangefinder 400 becomes smaller.

[0082] In this embodiment, the second vision camera 300 can refer to the MT-U12010GM-G100 camera and the matching camera lens MVL-HF0824M-10MP, which has a matching vision controller.

The transmission gear set includes a drive gear 401 disposed in the gear housing 4 and connected to the output end of the transverse reducer 202, and two transition gears 402 that mesh symmetrically with the drive gear 401. The open gear 403 is located between the two transition gears 402 and meshes symmetrically with the two transition gears 402.

[0089] In this embodiment, the gear housing 4 is connected to the housing 2, and a handle 7 is provided on the top of the gear housing 4.

[0090] In this embodiment, the floor support 5 includes a base plate 501, a top plate 503, and two trapezoidal side frames 502 connecting the base plate 501 and the top plate 503. A fixing plate 505 is provided on the trapezoidal side frame 502, and a support bolt 504 passes through the fixing plate 505. Two clamping plates 506 are provided on the top of the top plate 503. The clamping plates 506 and the first pin hole 104 of the double threaded telescopic rod 1 are connected by a pin with a threaded end. The support bolt 504 is used to abut against the side of the base plate for stabilization. The U-shaped bracket 8 includes an L-shaped frame 801 and an L-shaped clamping plate 806 disposed on the L-shaped frame 801. The opening of the L-shaped frame 801 is provided with an inner vertical plate 803 and an outer vertical plate 802. The L-shaped frame 801 is provided with a waist-shaped hole 805 in the horizontal direction. An upper bolt (not shown in the figure) for connecting the inner vertical plate 803 passes through the waist-shaped hole 805. The inner vertical plate 803 can slide along the horizontal part of the L-shaped frame 801. A nut 804 is provided in the outer vertical plate 802. An adjusting screw 807 passes through the nut 804. The adjusting screw 807 abuts against the outer side of the inner vertical plate 803. The L-shaped clamping plate 806 and the first pin hole 104 of the double-threaded telescopic rod 1 are connected by a pin with a threaded end.

[0091] In this embodiment, during actual use, the two ends of the adjusting sleeve 106 are a first cylindrical part and a second cylindrical part. The first cylindrical part, the middle hexagonal part 102 and the second cylindrical part are integrally formed. The interior of both ends of the middle hexagonal part 102 is provided with internal threads that correspond to the first threaded rod 105 and the second threaded rod 101.

[0092] In this embodiment, during actual use, the first threaded rod 105 passes through the first cylindrical portion and extends into the first end of the middle outer hexagonal portion 102, and the second threaded rod 101 passes through the second cylindrical portion and extends into the second end of the middle outer hexagonal portion 102.

[0093] In this embodiment, the first cylindrical part and the second cylindrical part are provided in actual use to guide and limit the first threaded rod 105 and the second threaded rod 101, so as to facilitate the adjustment of the threaded sleeve 106 to rotate and drive the first threaded rod 105 and the second threaded rod 101 to move closer or further apart axially; in addition, it can also increase the connection strength at the threaded connection of the first threaded rod 105 and the second threaded rod 101, making the connection reliable and improving the safety of construction and adjustment.

[0094] In this embodiment, during actual use, the first threaded rod 105 is a positive thread and the second threaded rod 101 is a negative thread. By reversing the thread direction, the adjusting sleeve 106 rotates, causing the first threaded rod 105 and the second threaded rod 101 to move axially closer or further apart.

[0095] In this embodiment, during actual use, the first pin hole 104 is located on the first outer hexagonal portion 103 of the first lead screw, and the second pin hole 108 is located on the second outer hexagonal portion 107 of the second lead screw.

[0096] In this embodiment, during actual use, the bottom opening of the limiting hole 601, the bottom opening of the opening gear 403, and the bottom opening of the positioning seat 3 are for fitting the transverse fine adjuster 15 onto the double threaded telescopic rod 1, and for fitting the opening gear 403 onto the middle outer hexagonal part 102, and for fitting the positioning seat 3 onto the first outer hexagonal part 103 of the first lead screw, thereby realizing the installation of the transverse fine adjuster 15 and making it easy to install and disassemble.

[0097] In this embodiment, during actual use, the center of the top semicircle of the limiting hole 601 coincides with the center of the first internal hexagonal hole of the open gear 403, so that the circle in which the semicircular hole is located is the circumcircle of the first internal hexagonal hole, thus providing better positioning.

[0098] In this embodiment, the limiting plate 6 is located on the gear cover plate 404.

[0099] In this embodiment, the limiting plate 6 is provided to ensure that when the lateral fine adjuster 15 is fitted onto the double-threaded telescopic rod 1, the top of the limiting hole 601 in the limiting plate 6 abuts against the middle outer hexagonal part 102. This limits the lateral fine adjuster 15 when the bottom opening of the open gear 403 rotates to the top, preventing the lateral fine adjuster 15 from moving downward and causing the middle outer hexagonal part 102 and the open gear 403 to be out of axis. This improves the continuity of the rotation adjustment of the middle outer hexagonal part 102 driven by the open gear 403.

[0100] In this embodiment, during actual use, the gear housing 4 and the housing 2 are connected, and a gear cover plate 404 is provided on the gear housing 4. The two ends of the axles of the driving gear 401, the transition gear 402 and the open gear 403 are inserted into the mounting holes of the gear housing 4 and the gear cover plate 404. The inner surfaces of the gear housing 4 and the gear cover plate 404 that are close to each other limit the two end faces of the gear so as to satisfy the rotation of the driving gear 401, the transition gear 402 and the open gear 403. The bottom of the gear housing 4 and the gear cover plate 404 are provided with an opening, and the bottom opening of the open gear 403 is connected to the opening. The outlet length of the opening of the gear housing 4 and the gear cover plate 404 is less than the diameter of the axle of the open gear 403 to prevent the open gear 403 from slipping.

[0101] In this embodiment, during actual use, the driving gear 401 and two transition gears 402 are set to drive the open gear 403 to rotate, and the two transition gears 402 respectively mesh with the open gear 403. This is to ensure that at least one part is engaged when the bottom opening of the open gear 403 rotates to the top, so as not to affect the meshing transmission. In addition, the number of gears is reduced compared to the past, thereby reducing weight.

[0102] In this embodiment, in actual use, the lateral rotating component 201 of the lateral power module is preferably a servo motor, but it can also be a frequency converter motor, stepper motor, DC brushless motor or hydraulic motor.

The precision planetary reducer is designed specifically for torque rotating components and has the characteristics of high precision, large torque, and low noise, making it suitable for industrial automation control scenarios.

[0104] In this embodiment, during actual connection, the U / V / W three-phase motor connection terminals of the horizontal motor driver 203 are connected to the U / V / W three-phase wiring terminals of the horizontal rotating component 201.

[0105] In this embodiment, in actual use, a control box is installed on the outer side of the outer rails of both the straight and side rails, and the PLC controller is located inside the control box.

[0106] In this embodiment, during actual use, the tablet computer sends control commands to the PLC controller, which controls the horizontal motor driver 203 to drive the horizontal rotating component 201 to rotate, while the centerline adjuster works to adjust.

[0107] In this embodiment, the oblong hole 805 is provided in actual use to loosen the upper bolt and release the locking of the inner vertical plate 803. The upper bolt slides along the oblong hole 805, thereby driving the inner vertical plate 803 to slide. When it moves to the required position, the upper bolt is tightened. Then, the adjusting screw 807 is rotated around the nut 804 until the adjusting screw 807 abuts against the outer side of the inner vertical plate 803, assisting in the abutment of the inner vertical plate 803, so that the vertical part of the L-shaped frame 801 and the inner vertical plate 803 are clamped on the retaining wall.

[0108] In this embodiment, the ground support 5 and U-shaped support 8 are set up in actual use to adapt to the environment of the turnout rail 10 to be adjusted. If there is a retaining wall, the L-shaped clamping plate 806 and the double threaded telescopic rod 1 are connected by clamping with the U-shaped support 8. If there is no retaining wall, i.e., the tunnel arch surface, bridge surface or road surface, the ground support 5 needs to be installed to install the double threaded telescopic rod 1.

[0109] In this embodiment, during actual use, the clamping plate 506 and the L-shaped clamping plate 806 are provided with a plurality of connecting pin holes that cooperate with the first pin hole 104. Pins are inserted into the corresponding connecting pin holes and the first pin hole 104, and a locking nut is installed at the protruding end of the pin to achieve hinge connection.

[0110] In this embodiment, the specific structure of the rail clamping member 9 is not limited, as long as it can clamp the rail 10 and the double threaded telescopic rod can drive the rail 10 to move.

[0111] like Figure 12 As shown, in this embodiment, it is further preferred that the rail clamping member 9 includes a bottom plate 904 passing through the bottom of the rail 10, a left L-shaped clamping block 902 welded to one end of the bottom plate 904, and a right L-shaped clamping block 903 bolted to the other end of the bottom plate 904, and a connecting ear plate 901 disposed at the end edge of the bottom plate 904. The connecting ear plate 901 is arranged close to the right L-shaped clamping block 903. The second pin hole 108 and the mounting hole on the connecting ear plate 901 are through which pins pass, and a locking nut is installed at the protruding end of the pin.

[0112] In this embodiment, the bolt installation of the right L-shaped clamp 903 is set so that when disassembling later, the bolt on the right L-shaped clamp 903 can be removed first, thereby removing the right L-shaped clamp and removing the pin in the connecting ear plate 901 and the second pin hole 108, thereby disengaging from the double threaded telescopic rod 1. Then, pull the left L-shaped clamp 902 and the bottom plate 904 out of the gap at the bottom of the rail 10.

[0113] In this embodiment, a left L-shaped clamping block 902 and a right L-shaped clamping block 903 are set on both sides of the web of the rail 10 to clamp the rail 10, and the rail 10 is moved laterally by the double threaded telescopic rod 1.

[0114] like Figure 13 As shown in this embodiment, in actual use, the movable wheel 1602 is a single-sided track wheel that can move along the rail, and has good stability.

[0115] In this embodiment, during actual use, the top of the connecting slide rail 1604 is located at the bottom of the extended beam 18, and the bottom of the connecting slide rail 1604 is open so that the sliding guide can be inserted into the slide rail 1604.

[0116] In this embodiment, in actual use, the connecting slide rail 1604 is a U-shaped slide rail, and the bottom is bent inward to form a lower bend edge.

[0117] In this embodiment, during actual use, the sliding guide includes a support plate 1609, two sets of upper and lower limiting rollers 1608 disposed in the middle of the support plate 1609, and two front and rear limiting rollers 1610 symmetrically disposed at both ends of the support plate 1609. The bottom of the support plate 1609 is provided with an upper connecting lug 1607.

[0118] In this embodiment, in actual use, such as Figure 14 As shown, the rolling surface of the upper and lower limiting rollers 1608 is in contact with the lower bent edge of the connecting slide rail 1604, and the rolling surface of the front and rear limiting rollers 1610 is close to the front and rear sides inside the connecting slide rail 1604.

[0119] In this embodiment, during actual use, the side of the long vehicle body 1601 is provided with a lower connecting lug, and the two ends of the connecting rod 1603 are respectively hinged to the upper connecting lug 1607 and the lower connecting lug via quick-release pins 1606.

[0120] In this embodiment, in actual use, one end of the long vehicle body 1601 is provided with two movable wheels 1602 through the first wheel frame, and the other end of the long vehicle body 1601 is provided with one movable wheel 1602 through the second wheel frame. A support rod 1607 is provided between the elongated vehicle body 1601 and the first wheel frame to improve stability.

[0121] In this embodiment, in actual use, a movable wheel 1602 is set up close to the fine-tuning mobile vehicle 11 in order to reduce space occupation and adapt to the limited space under the fine-tuning mobile vehicle 11.

[0122] In this embodiment, during actual use, the fine-tuning mobile vehicle 11 is equipped with a main controller 135, which can be a PLC.

[0123] In this embodiment, during actual use, the Amberg track inspection trolley 18 is connected to the main controller 135 so that the data detected by the Amberg track inspection trolley 18 is sent to the main controller 135.

[0124] In this embodiment, during actual use, the first vision camera 132 and the second vision camera 300 are connected to the vision controller, which is connected to the main controller 135, so that the displacement of the center of the elevation screw relative to the center of the bottom sleeve and the data of the fork number are sent to the main controller 135.

[0125] In this embodiment, during actual use, a wireless router is installed in the long vehicle body 1601. The wireless router and the main controller 135 are connected by wired or wireless means so that the tilt angle detected by the tilt sensor 160 is sent to the main controller 135 through the wireless router.

[0126] The tilt sensor 160 is connected to the display screen 1605 so that the detected tilt angle is synchronously displayed on the display screen 1605.

[0127] In this embodiment, in actual use, the control and connection between the main controller 135 and the torque rotating component 1001, the transverse rotating component 8001 and the lifting rotating component 5001 can be referenced to the control and connection between the PLC controller and multiple transverse rotating components 201.

[0128] In this embodiment, during actual use, both the laser rangefinder 400 and the proximity switch 600 are connected to the main controller 135 to realize the acquisition of detection data and signals.

[0129] like Figure 16 As shown, the two extension beams 14 are a long extension beam and a short extension beam, respectively. The inner end of the short extension beam is provided with two outer connecting plates 142. One end of the crossbeam 13 is provided with an inner connecting plate 136. The inner connecting plate 136 extends into the two outer connecting plates 142 and is detachably connected by a pin with threads at both ends.

[0130] When the inner connecting plate 136 and the outer connecting plate 142 are connected by a pin, the short extension beam and the cross beam 13 can be swung and adjusted; when the pin in the connecting plate 136 and the outer connecting plate 142 is removed, the short extension beam and the cross beam 13 are not connected, and the short extension beam and the long extension beam can be folded.

[0131] In this embodiment, in actual use, the place where one end of the long extension beam and the crossbeam 13 is hinged is recorded as the swing point. One telescopic rod 17 extends and retracts to drive the long extension beam to swing around the swing point; with the short extension beam and the crossbeam 13 connected, another telescopic rod 17 extends and retracts to drive the short extension beam and the crossbeam 13 to swing around the swing point as well. If there is only one turnout sleeper, then the projections of the crossbeam 13 and the extension beam 14 are parallel to the turnout sleeper; thereby enabling multiple elevation adjusters 12 to adapt to the elevation screw when they move laterally along the crossbeam 13. If there are two turnout sleepers, the projections of the short extension beam and the crossbeam 13 are parallel to the turnout sleeper under the straight section, and the projection of the long extension beam is parallel to the turnout sleeper under the side section.

[0132] In this embodiment, four elevation adjusters 12 are used in actual operation: one on the short extension beam, one on the crossbeam 13, and the other two on the long extension beam. The structural dimensions and number can be adjusted adaptively in practice.

[0133] In this embodiment, during actual use, a column 19 is installed on the top of the fine-tuning mobile vehicle 11. A camera, a lighting fixture, and a zone radar safety alarm system 1901 are installed on the top of the column 19. The zone radar safety alarm system 1901 can be a reference to the forklift zone alarm system of the brand Loman. This improves safety and provides lighting and video monitoring functions.

[0134] In this embodiment, in actual use, the column 19 can be a telescopic column. The bottom of the column 19 is hinged to the top of the fine-tuning moving vehicle 11, and can swing upward to open vertically or swing downward to close.

[0135] A method for fine-tuning the elevation of a turnout, the method comprising the following steps: Step S1: The fine-tuning mobile car 11 pulls the Amberg track inspection trolley 18 to move along the straight track. The first vision camera 132 on the crossbeam 13 captures the QR code image of the turnout sleeper and sends it to the vision controller to obtain the current turnout sleeper number. Step S2: The main controller 136 inside the fine-tuning moving car 11 receives the current turnout sleeper number and obtains the lateral displacement of the elevation screw relative to the elevation adjuster from the elevation adjuster and elevation screw phase lateral displacement database. Step S3: Adjust the elevation adjuster 12 to move laterally according to the lateral displacement of the elevation screw relative to the elevation adjuster on the current turnout sleeper number, and the lateral displacement satisfies step S2. Step S4: The second vision camera 300 at the bottom of the elevation adjuster 12 captures an image of the elevation screw on the current turnout sleeper number. With the center of the second vision camera 300 and the center of the bottom sleeve 1007 fixed at the same position, the displacement of the center of the elevation screw relative to the center of the bottom sleeve 1007 is obtained after processing by the vision controller. Step S5: Based on the displacement of the center of the elevation screw relative to the center of the bottom sleeve 1007, control the elevation adjuster 12 to move continuously so that the center of the elevation screw and the center of the bottom sleeve coincide; and drive the sleeve component to descend through the lifting mechanism 500 so that the bottom sleeve 1007 is fitted onto the top of the elevation screw. Step S6: Obtain the elevation error value at the current turnout sleeper number using the Amberg track inspection trolley 18, and based on the elevation error value at the current turnout sleeper number, finely adjust the elevation screw at the current turnout sleeper number using the elevation adjuster on the straight track, with the adjustment amount being the elevation error value. The elevation of the elevation screw on the side stock is finely adjusted by the elevation adjuster on the side stock until the inclination angle detected by the inclination angle detection trolley 16 on the side stock is zero. Step S7: Repeat step S6 multiple times until the elevation error value at the current turnout sleeper number is less than or equal to ±0.3mm. Then the current turnout sleeper elevation meets the construction design requirements. Step S8: Following the methods of steps S1 to S7, complete the elevation adjustment of the remaining turnout sleepers in sequence.

[0136] A method for fine-tuning the centerline of a turnout, the method comprising the following steps: Step A1: The fine-tuning moving car 11 pulls the Amberg track inspection trolley 18 to move along the straight track and inspect the turnout sleepers equipped with centerline adjusters to obtain the centerline error value at each turnout sleeper equipped with a centerline adjuster. Step A2: The rail 10 of the turnout is moved laterally by multiple centerline adjusters, and the adjustment amount is the centerline error value. Step A3: Repeat steps A1 and A2 multiple times until the centerline error value is less than ±0.3mm, then the turnout centerline meets the construction design requirements; When multiple centerline adjusters are installed to adjust the lateral movement of the turnout rail 10, the specific process is as follows: Step A: Connect the EtherCAT port of the PLC controller to the EtherCAT IN port of the first horizontal motor driver 203 using a standard shielded network cable. Connect the EtherCAT IN and EtherCAT OUT ports of the remaining horizontal motor drivers 203 in the multiple centerline adjusters in series using a standard shielded network cable. The PLC controller is wirelessly connected to the tablet computer via a Wi-Fi communication module. Step B: The tablet computer receives the centerline error value and sends an adjustment command to the PLC controller. The PLC controller receives the adjustment command and sends it to the lateral motor driver 203 using the EtherCAT protocol. The lateral motor driver 203 controls the lateral rotating component 201 to work. The lateral rotating component 201 drives the lateral reducer 202 to rotate. The rotation of the lateral reducer 202 drives the open gear 403 to rotate sequentially through the drive gear 401 and the transition gear 402. When the open gear 403 is fitted under the middle outer hexagonal part 102, it drives the adjusting screw sleeve 106 to rotate, so that the double threaded telescopic rod 1 extends. The double threaded telescopic rod 1 then pushes the rail 10 of the turnout to move laterally through the rail clamp 9. Alternatively, the lateral rotating component 201 can be operated to rotate in the opposite direction, so that the double threaded telescopic rod 1 retracts. The double threaded telescopic rod 1 then pushes the rail 10 of the turnout to move laterally in the opposite direction through the rail clamp 9, and the adjustment amount is the centerline error value.

[0137] A method for fine-tuning a turnout, the method comprising the following steps: Step 1: Install multiple centerline adjusters along the outer rails of the straight and side rails; Step 2: Hoist the fine-tuning moving vehicle onto the straight section; Step 3: Place the Amberg track inspection trolley 18 on the straight track and the tilt detection trolley 16 on the side track; connect both the Amberg track inspection trolley 18 and the tilt detection trolley 16 to the fine-tuning moving car. Step 4: Fine-tuning the moving car to pull the Amberg track inspection trolley 18 along the straight track to obtain the centerline error value at the turnout sleeper where the centerline adjuster is installed; Step 5: Based on the centerline error value, multiple centerline adjusters automatically adjust the centerline of the turnout using a tablet computer. Step 6: Repeat steps 4 and 5 for the next automatic adjustment until the centerline error is less than ±0.3mm; Step 7: Fine-tune the movement of the mobile car to pull the Amberg track inspection trolley 18 along the straight track to obtain the current elevation error value at the turnout sleeper; Step 8: Fine-tune the moving vehicle control elevation adjuster and fine-tune all elevation screws at the fork bolster until the elevation error is less than ±0.3mm; Step 9: Following the methods in Steps 7 and 8, adjust the next turnout sleeper until the elevation error is less than ±0.3mm; Step 10: Remove all lateral fine adjusters. Turnout fine adjustment is now complete.

[0138] In this embodiment, it should be noted that the initial positions of the four elevation adjusters 12 are all located at the beam ends. Therefore, the database of phase lateral displacement of the elevation adjusters and elevation screws is obtained by manual measurement of the initial positions of the elevation adjusters 12.

[0139] In this embodiment, the drive box 100 is equipped with three motor drivers for driving the transverse rotating component 8001, the lifting rotating component 5001, and the torque rotating component 1001, respectively. The Ethercat ports of the three motor drivers are connected in series using standard shielded network cables, and one motor driver is connected to the Ethercat port of the main controller 136.

[0140] In this embodiment, during specific implementation, the main controller 136 controls the lateral movement rotating component 8001 to work according to the lateral movement amount of the elevation screw relative to the elevation adjuster on the current turnout sleeper number. The lateral movement rotating component 8001 drives the gear 8003 to rotate through the third reducer 8002. The gear 8003 rotates along the rack 134, and then the elevation adjuster 12 moves laterally along the slide rail 133 until the lateral movement amount meets the requirements of step S2.

[0141] In this embodiment, the PLC controller is an XLH-24A16LPLC controller, and the Wi-Fi communication module is a USR-G806W module.

[0142] In this embodiment, during actual use, the fine-tuning mobile vehicle 11 can also pull the Amberg track inspection trolley 18 to move along the side track for elevation and center fine-tuning.

[0143] In this embodiment, during actual use, the lifting mechanism 500 in step S5 drives the sleeve component to descend, and the specific process is as follows: The main controller 135 controls the operation of the lifting and rotating component 5001, and drives the lead screw 5004 to rotate through the second reducer 5002. With the lead screw 5004 and the lead screw nut 5005 threadedly connected, the lead screw nut 5005 moves downward along the lead screw 5004. Then, the lead screw nut 5005 drives the power component and the sleeve component to move downward through the first mounting base 1012. The first mounting base 1012 slides along the linear guide rail through the guide rail slider. In step S6, the elevation adjuster performs fine-tuning of the elevation screw. The specific process is as follows: When the sleeve component moves down and is fitted onto the top of the elevation screw, the sleeve component gradually moves down, the elastic element gradually contracts, and the annular plate 1014 moves closer to the proximity switch 600 until the proximity switch 600 detects the annular plate 1014. Then, the proximity switch 600 outputs a signal to the main controller 135, and the main controller 135 controls the sleeve component to stop moving down, thereby ensuring that the contracted elastic element exerts a downward force on the elevation screw so that the bottom of the elevation screw contacts the steel pad on the base plate. After that, the main controller 135 controls the torque rotating component 1001 to work and drives the first reducer 1002 to rotate, and the sleeve component rotates. With the sleeve component driving the elevation screw to rotate, the elevation of the turnout sleeper is adjusted because the elevation screw and the turnout sleeper are threadedly connected.

[0144] In this embodiment, it should be noted that the turnout includes a straight track and a side track, and both the straight track and the side track have rails 10.

[0145] In this embodiment, it should be noted that the elevation adjuster and centerline adjuster in the system can also be used in the fine-tuning construction of the double-block ballastless track panel.

[0146] In this embodiment, it should be noted that a laser rangefinder 400 can also be used for positioning. The laser rangefinder 400 can measure the distance. When the system is located above the turnout sleeper, the distance detected by the laser rangefinder 400 becomes smaller, thus positioning the turnout sleeper.

[0147] In summary, the present invention is reasonably designed and can quickly complete the fine adjustment of the elevation and centerline of the turnout, reduce manual assistance, save manpower and material resources, and improve construction efficiency.

[0148] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
