Description

Technical Field

[0001] This invention belongs to the field of double-block sleeper construction technology, and in particular relates to a double-block sleeper splitting platform and its construction method. Background Technology

[0002] In the construction of twin-block ballastless track, the core purpose of connecting the twin-block sleepers with the fine-tuning track panels is to achieve precise positioning and stable support of the track in the construction of high-speed railway ballastless track. However, currently, the connection between the twin-block sleepers and the fine-tuning track panels is carried out on sleeper-sharing flatcars. This requires manual labor to hoist each twin-block sleeper onto the flatcar for connection, which is labor-intensive, inefficient, and the track gauge is fixed and cannot be adjusted.

[0003] Therefore, a well-designed double-block sleeper distribution platform is needed to install the double-block sleepers on each distribution unit at the distribution station. By adjusting the spacing between each distribution unit, the spacing between the double-block sleepers can be adjusted, which improves the adaptability, reduces labor intensity, improves construction efficiency, and facilitates subsequent assembly with the double-block fine-tuning track panel. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a double-block sleeper distribution platform to address the shortcomings of the prior art. The platform is reasonably designed to install double-block sleepers on each distribution unit at the distribution station. By adjusting the spacing between each distribution unit, the spacing between the double-block sleepers can be adjusted, thereby improving the adaptability, reducing labor intensity, improving construction efficiency, and facilitating subsequent assembly with double-block fine-tuning rail panels.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a double-block sleeper splitting platform, characterized in that: it includes a platform base, a first sleeper splitting station and a second sleeper splitting station set on the platform base, and a support leg assembly set at the bottom of the platform base, wherein the support leg assembly can drive the platform base to rise and fall. Both the first and second pillow-separating stations include multiple pillow-separating units; Each of the sleeper-sleeper units includes a platform top plate for mounting double-block sleepers, a gear located at the bottom of the platform top plate, and a sleeper-sleeper drive mechanism that drives the gear to roll along the length of the platform base. The sleeper-sleeper drive mechanism drives multiple sleeper-sleeper units to open and close with each other.

[0006] The aforementioned double-block sleeper distribution platform further includes a platform base comprising a platform bottom truss, side wall panels surrounding the sides of the platform bottom truss, and a top plate disposed at the top of the platform bottom truss. The platform bottom truss is provided with two symmetrically arranged outer longitudinal beams and an intermediate longitudinal beam disposed between the two outer longitudinal beams. A rack for gear meshing is provided on the intermediate longitudinal beam, and the rack is arranged along the length direction of the platform base; Two symmetrically arranged sliders are provided at the bottom of the platform top plate, and a longitudinal slide rail is provided on the outer longitudinal beam. The sliders are installed on the longitudinal slide rail, which is arranged along the length of the platform base.

[0007] In the aforementioned double-block sleeper distribution platform, a lateral limiting component is further provided on the top of the platform top plate. The lateral limiting component includes a fixed limiting seat and a movable limiting seat provided on the top of the platform top plate, and the distance between the movable limiting seat and the fixed limiting seat is adjustable. The bottom of the platform top plate is provided with two symmetrically arranged longitudinal limiting components. The longitudinal limiting components include hydraulic angle cylinders provided at the bottom of both ends of the platform top plate and limiting plates provided on the hydraulic angle cylinders.

[0008] In the aforementioned double-block sleeper-sharing platform, a bottom shell is further provided around the bottom of the platform's top plate. The sleeper-sharing drive mechanism is located inside the bottom shell. The sleeper-sharing drive mechanism includes a drive motor, a reducer, and a gear that are sequentially connected in transmission. The output shaft of the drive motor is connected in transmission to the input end of the reducer. A vertical shaft is provided at the output end of the reducer. The gear is installed at the end of the vertical shaft that extends out of the bottom shell.

[0009] In the aforementioned double-block sleeper distribution platform, the top plate of the platform is provided with an elongated hole for the movable limiting seat to move, and the top of the movable limiting seat extends out of the elongated hole. The bottom housing is provided with a moving adjustment mechanism that drives the movable limiting seat to move. The moving adjustment mechanism includes an L-shaped seat set in the bottom of the platform top plate, a hydraulic cylinder set on the L-shaped seat, a connecting seat set in the telescopic end of the hydraulic cylinder, and a sliding plate connected to the top of the connecting seat. The movable limiting seat is set on the sliding plate. Two symmetrically arranged L-shaped plates are set in the bottom of the platform top plate. The edge of the sliding plate slides against the horizontal part of the L-shaped plate.

[0010] In the aforementioned double-block sleeper-sharing platform, the number of support leg assemblies is four, and the four support leg assemblies are arranged in a rectangular pattern. Each of the outrigger assemblies includes an inner outrigger, an outrigger cylinder disposed inside the inner outrigger, an outer outrigger sleeved outside the inner outrigger, and a base plate disposed at the bottom of the inner outrigger. A hinge shaft passes through the bottom of the inner outrigger, the base plate, and the bottom end of the outrigger cylinder. The top of the inner outrigger is lower than the top of the outer outrigger. The top of the outer outrigger and the upper end of the outrigger cylinder are connected by a connecting screw. The extension and retraction of the outrigger cylinder drives the raising and lowering of the outer outrigger.

[0011] In the aforementioned double-block sleeper distribution platform, an end-limiting frame is further provided at one end of the platform base. The end-limiting frame includes an end-support frame at one end of the platform base, a limiting support seat on the upper side of the end-support frame, a limiting guide seat on the limiting support seat, and a transmission rod passing through the limiting support seat. A limit switch is provided inside the limiting support seat, and a sleeve is provided inside the top of the limiting support seat. A spring is provided inside the sleeve. The transmission rod includes an upper transmission rod, a limiting circular plate, and a lower transmission rod connected in sequence. The upper transmission rod extends out of the upper top plate of the limiting support seat. The limiting circular plate is located inside the sleeve and between the upper top plate of the limiting support seat and the spring. The lower transmission rod passes through the spring and the sleeve and can act on the limit switch.

[0012] In the aforementioned double-block sleeper distribution platform, a middle support frame is provided at the end of the platform top plate of the middle sleeper distribution unit. The middle support frame includes an extension plate provided at the end of the platform top plate of the middle sleeper distribution unit. A vertical column is provided on the extension plate, a support plate is provided on the vertical column, a middle guide seat is provided on the support plate, and an end slider that cooperates with the longitudinal slide rail is provided inside the extension plate. Adjacent pillow units are connected by steel wire ropes; The platform base is equipped with a dual-axis tilt sensor.

[0013] A construction method for separating double-block sleepers using a double-block sleeper separating platform is also provided. This method includes the following steps: Step 1: Install the double-block sleepers onto each of the aforementioned sleeper units; Step 2: Limit the double-block sleeper using lateral and longitudinal limiting components; Step 3: Operate the sleeper-sharing drive mechanism within the sleeper-sharing unit. The sleeper-sharing drive mechanism drives the gears to roll along the platform base, so that the sleeper-sharing unit moves along the platform base until the spacing between two adjacent double-block sleepers meets the construction design requirements. Step 4: Install the double-block fine-tuning rail panel on the double-block sleeper; Step 5: Install the inspection trolley on the rails of the double-block fine-tuning rail panel to ensure that the distance between the rails and the top plate of the platform base is the same.

[0014] The above construction method, further, step two, the specific process is as follows: Step 201: After placing the double-block sleeper on the top plate of the sleeper unit platform, make the fixing limit seat on the sleeper unit fit against the inner wall of one of the concrete sleeper blocks in the double-block sleeper. Step 202: When the extension rod of the hydraulic cylinder extends or retracts, the connecting seat drives the sliding plate to slide along the horizontal part of the L-shaped plate. During the sliding process, the sliding plate drives the movable limiting seat to move in the elongated hole to move closer to or away from the fixed limiting seat until the movable limiting seat fits against the inner wall of the other concrete sleeper block in the double-block sleeper. Step 203: The hydraulic angle cylinder drives the limit plate to swing 90 degrees. The limit plate is vertical and moves slightly closer to the double-block sleeper until the limit plate clamps the outer side of the double-block sleeper.

[0015] Compared with the prior art, the present invention has the following advantages: 1. The present invention has a simple structure, reasonable design, and is easy to install and deploy, and is convenient to control, realizing the separate sleeper of the double-block sleeper.

[0016] 2. The first and second sleeper-splitting stations of this invention both include multiple sleeper-splitting units. When there are 8 double-block sleepers, only the first sleeper-splitting station is needed. If there are 9-12 double-block sleepers, the first and second sleeper-splitting stations need to work together. This improves the adaptability and increases the number of double-block sleepers.

[0017] 3. After the double-block sleeper of the present invention is installed, the lateral limitation of the double-block sleeper is achieved by the fixed limiting seat and the movable limiting seat adhering to the inner side wall of the double-block sleeper; the longitudinal limitation of the double-block sleeper is achieved by the limiting plate adhering to the outer side wall of the double-block sleeper; and the distance between the fixed limiting seat and the movable limiting seat can be adjusted, thereby adapting to different double-block sleepers and improving the adaptability range.

[0018] 4. The present invention is provided with a transmission rod so that when the track panel is installed, it presses against the upper transmission rod. The upper transmission rod pushes the limiting circular plate to move downward and compress the spring. The lower transmission rod then moves downward and extends out of the sleeve until it contacts the limit switch. The limit switch then sends a control signal to cut off the power supply to the drive motor, ensuring safe operation thereafter.

[0019] 5. The present invention includes a sleeper-splitting drive mechanism so that when the sleeper-splitting drive mechanism is working, it drives the gears to roll along the platform base, so that the sleeper-splitting units move along the platform base until the spacing between two adjacent double-block sleepers meets the construction design requirements.

[0020] 6. The split-pillow drive mechanism of the present invention drives the gear and rack to mesh. The gear rotates while meshing with the rack to roll, thereby driving the split-pillow unit to move along the platform base, so that multiple split-pillow units can open and close with each other; and the longitudinal slide rail and slider cooperate to guide the movement process.

[0021] 7. The platform base of this invention has a leveling function. It detects the angle error data in two directions through a dual-axis tilt sensor and drives the extension and retraction of the outrigger cylinders to level the sleeper platform. Each sleeper platform unit is an assembly with independent adjustment of sleeper spacing.

[0022] 8. This invention uses steel wire ropes to limit the extreme spacing of adjacent sleeper installation platforms, preventing equipment safety accidents caused by equipment failure; and it is equipped with limit switches to detect the presence of rails, ensuring that the equipment control system and power supply are cut off when the platform is placing the rail panels, eliminating personnel safety accidents caused by equipment failure during manual operation. In addition, a detection trolley is also provided to detect whether sleeper pads are missing during the installation process.

[0023] 9. The construction method for splitting the double-block sleeper of the present invention is simple, convenient and easy to control, and the splitting of the double-block sleeper facilitates the subsequent assembly of the double-block fine-tuning track panel.

[0024] 10. The ballastless track method of the present invention has good performance. First, double-block sleepers are installed on each of the sleeper sub-units, and the double-block sleepers are limited by lateral and longitudinal limiting components. Second, the sleeper sub-unit drive mechanism is operated, which drives the gear to roll along the platform base, so that the sleeper sub-unit moves along the platform base until the spacing between two adjacent double-block sleepers meets the construction design requirements. Next, double-block fine-tuning rail panels are installed on the double-block sleepers. Finally, a testing trolley is installed on the rails of the double-block fine-tuning rail panels to ensure that the distance between the rails and the top plate of the platform base is the same.

[0025] In summary, the present invention is reasonably designed. By installing the double-block sleepers on each sleeper unit at the sleeper distribution station, and adjusting the spacing between each sleeper unit, the spacing of the double-block sleepers can be adjusted, thereby improving the adaptability, reducing labor intensity, improving construction efficiency, and facilitating subsequent assembly with the double-block fine-tuning track panel.

[0057] In this embodiment, in actual use, by setting an inner end plate 26 and an outer end plate 22, and with the slider 27 located between the outer end plate 22 and the inner end plate 26, it is to prevent dust, debris and other impurities from entering the interior and to avoid the slider getting stuck.

[0058] In this embodiment, during actual use, one end of the base plate 24 is provided with an opening, and an interface mounting plate 25 is provided at the opening. The interface mounting plate 25 is mounted on the inner end plate 26, and the bottom surface of the interface mounting plate 25 is flush with the bottom surface of the base plate 24.

[0059] In this embodiment, the interface mounting plate 25 and the base plate 24 are designed as separate units in actual use. This is because the interface mounting plate 25 is equipped with an aviation plug 211 and a mounting hole 212. A hydraulic through-plate connector is installed in the mounting hole. The aviation plug 211 is used to connect cables, and the hydraulic through-plate connector is used to connect oil pipes. This facilitates the separation of the base plate 24 and the interface mounting plate 25, enabling the base plate 24 to be detachably installed and facilitating the maintenance of the internal support drive mechanism.

[0060] In this embodiment, during actual use, the bottom of both ends of the platform top plate 21 is provided with cylinder covers 210 for the installation of hydraulic angle cylinders 29. This provides an installation base for the hydraulic angle cylinders 29 and prevents damage to the hydraulic angle cylinders 29 caused by foreign objects colliding with them during movement.

[0061] In this embodiment, in actual use, the reducer 32 is a worm gear reducer, and more specifically a hollow shaft type right-angle worm gear reducer. The input end and output end are arranged at 90° perpendicularly, which can change the power transmission direction without additional steering mechanism, significantly saving equipment space.

[0062] In this embodiment, during actual use, the output shaft of the drive motor 31 is connected to the input end of the reducer 32. The output end of the reducer 32 is provided with a vertical shaft 34, and the gear 33 is located at the end of the vertical shaft 34 and is connected in a transmission manner. The transmission connection method is not limited, and can specifically be a key connection, etc.

[0063] The base plate 24 has a through hole for the end of the vertical shaft 34 to pass through; The drive motor 31 has a built-in encoder, which can move a distance according to the number of rotations.

[0064] In this embodiment, during actual use, a motor driver 35 is provided inside the bottom housing. The motor driver 35 is electrically connected to the drive motor 31 and is used to control the rotation of the drive motor 31. This connection and control method can refer to conventional methods.

[0065] In this embodiment, during actual use, a solenoid valve 45 is installed inside the bottom housing. The solenoid valve 45 is installed on the oil supply pipe of the hydraulic cylinder 4. The connection and control method can refer to the conventional method.

[0066] In this embodiment, the L-shaped plate 43 is set in actual use to support and limit the edge of the slide plate 44, and further ensure the accurate horizontal movement of the slide plate 44 and the movable limit seat 213.

[0067] In this embodiment, when the extension rod of the hydraulic cylinder 4 is extended, the connecting seat 42 drives the slide plate 44 to slide along the horizontal part of the L-shaped plate 43. During the sliding process, the slide plate 44 drives the movable limiting seat 213 to move in the elongated hole 215 to move closer to the fixed limiting seat 214, and the distance between the movable limiting seat 213 and the fixed limiting seat 214 is reduced. Alternatively, when the telescopic rod of the hydraulic cylinder 4 retracts, the connecting seat 42 drives the slide plate 44 to slide in the opposite direction along the horizontal part of the L-shaped plate 43. During the reverse sliding process, the slide plate 44 drives the movable limit seat 213 to move in the elongated hole 215 to move away from the fixed limit seat 214, thereby increasing the distance between the movable limit seat 213 and the fixed limit seat 214.

[0068] In this embodiment, during actual use, the hydraulic rotary cylinder 29 achieves piston rotation and linear clamping action through hydraulic drive. For details, please refer to the hydraulic rotary cylinder with single pressure plate model HSL-63SL-90.

[0069] like Figure 9 As shown, in this embodiment, in actual use, the end of the limiting plate 28 away from the hydraulic angle cylinder 29 is the enlarged end, and the side of the limiting plate 28 near the platform top plate 21 forms a limiting inclined surface 281, which adapts to the outer side of the double-block sleeper 15.

[0070] In this embodiment, during actual use, the drive motor 31 rotates and drives the vertical shaft 34 to rotate through the reducer 32, and the rotation of the vertical shaft 34 drives the gear 33 to rotate.

[0071] In this embodiment, during actual use, the longitudinal slide rail 9 is mounted on the outer longitudinal beam 64, and both have the same length direction. There are two top plates 63 at the top of the platform bottom truss 66, arranged along both sides with a gap between them.

[0072] In this embodiment, the bottom of the inner support leg 51 is provided with two inner connecting plates 511, and the base plate 54 is provided with two symmetrically arranged outer connecting plates 512 that fit the inner connecting plates 511. The bottom of the support leg cylinder 52 is provided with a lower connecting lug 513, which is located between the two inner connecting plates 511. A lower spacer 514 is provided between the two inner connecting plates 511 and the lower connecting lug 513, and the lower spacer 514 is sleeved on the hinge shaft 55. The hinge shaft 55 passes through the outer connecting plate 512, the inner connecting plate 511, the lower spacer 514, and the lower connecting lug 513 to achieve hinge.

[0073] In this embodiment, a hinge shaft 55 is provided between the bottom of the inner support leg 51, the base plate 54, and the bottom of the support leg cylinder 52. This is so that when the inner support leg 51, the support leg cylinder 52, and the outer support leg 53 are vertical, only the base plate 54 can swing around the hinge shaft 55, thereby allowing the base plate 54 to adapt to different installation foundations.

[0074] In this embodiment, the upper end of the outrigger cylinder 52 is provided with an upper connecting lug 57, and an upper spacer 58 is provided between the two opposite side walls of the outrigger cylinder 52 and the upper connecting lug 57. The connecting screw 59 passes through the two opposite side walls of the outrigger cylinder 52, the upper spacer 58 and the upper connecting lug 57, thereby connecting the top of the outer outrigger 53 and the upper end of the outrigger cylinder 52.

[0075] In this embodiment, the lower partition 514 and the upper partition 58 are respectively positioned for the lower connecting ear 513 and the upper connecting ear 57 to ensure that the outrigger cylinder 52 and the inner outrigger 51 are coaxially arranged with the outer outrigger 53.

[0076] In this embodiment, when the outrigger cylinder 52 extends, the upper end of the outrigger cylinder 52 drives the outer outrigger 53 to slide along the height direction of the inner outrigger 51, and the top of the outrigger assembly 5 rises. Alternatively, when the outrigger cylinder 52 retracts, the upper end of the outrigger cylinder 52 drives the outer outrigger 53 to slide in the opposite direction along the height of the inner outrigger 51, thus lowering the top of the outrigger assembly 5.

[0077] In this embodiment, multiple sliding plates are provided on the outer side wall of the inner support leg 51 so that the inner side wall of the outer support leg 53 fits against the sliding plates. This not only limits the coaxial arrangement of the outer support leg 53, the inner support leg 51 and the support leg cylinder 52, but also ensures the sliding path and reduces friction.

[0078] In this embodiment, the angle error data in two directions is detected by a dual-axis tilt sensor, which drives the outrigger cylinders to extend and retract, thereby leveling the split platform.

[0079] In this embodiment, a base plate 68 is provided on the platform base 6, and an expansion plate 56 connected to the base plate 68 is provided on the top of the outer support leg 53. The expansion plate 56 and the base plate 68 are connected by multiple bolts 510. The inner support leg 51, the support leg cylinder 52 and the outer support leg 53 are arranged vertically.

[0080] In this embodiment, the top of the outer support leg 53 is provided with a top plate, and the top surface of the top plate is attached to the bottom surface of the top plate on the platform base 6.

[0081] In this embodiment, during actual use, the sleeve 75 is installed in the upper top plate of the limiting support 72 through the outward expansion edge. The upper top plate is horizontally arranged, and the limiting switch 74 is set on the vertical plate of the limiting support 72 and located at the bottom of the upper top plate. The area of ​​the limiting circular plate 762 is larger than the cross-section of the spring 77, and the bottom of the sleeve 75 is provided with a through hole for the lower transmission rod 763 to pass through.

[0082] In this embodiment, during actual use, when the installed rail panel presses against the upper transmission rod 761, the upper transmission rod 761 pushes the limiting circular plate 762 downward to compress the spring 77. This causes the lower transmission rod 763 to move downward and extend out of the sleeve until it contacts the limit switch 74. The limit switch 74 then sends a control signal to cut off the power supply to the drive motor 31, ensuring safe operation afterwards. When the rail panel is subsequently removed, the spring 77 pushes the upper transmission rod 761 back to its original position.

[0083] In this embodiment, in actual use, the limit switch 74 can be referenced to the travel limit switch.

[0084] In this embodiment, during actual use, the fixed limiting seat 214 and the movable limiting seat 213 are attached to the inner wall of the double-block sleeper 15 to achieve lateral limiting of the double-block sleeper 15; the limiting plate 28 is attached to the outer wall of the double-block sleeper 15 to achieve longitudinal limiting of the double-block sleeper 15; and the distance between the fixed limiting seat 214 and the movable limiting seat 213 is adjustable, thereby adapting to different double-block sleepers 15 and improving the adaptability range.

[0085] In this embodiment, during actual use, the upper top plate of the limiting support seat 72 and the support plate 83 are provided for the rails in the rail panel to be placed, and the limiting guide seat 73 and the intermediate guide seat 84 limit the rails to ensure that the rails are placed in place.

[0086] In this embodiment, in actual use, two adjacent pillow units 2 are connected by a steel wire rope. The steel wire rope is used to limit the maximum distance of movement between the two pillow units 2 and to prevent damage to components caused by abnormal operation of the pillow units 2.

[0087] In this embodiment, in actual use, the double-block fine-tuning track panel 12 can refer to the double-block fine-tuning track panel 12 composed of two rails and multiple sets of adjustment mechanisms in a double-block ballastless track fine-tuning track panel system and method in patent CN202311507129.7.

[0088] In this embodiment, the inspection trolley 11 is equipped with two laser sensors. The bottom of the inspection trolley 11 housing has an opening for the laser to pass through, and the detection surfaces of the two laser sensors are arranged facing the rail. In this way, when the inspection trolley 11 moves on the rails of the double-block fine-tuning rail panel 12, the distance between the rails and the top plate of the platform base 6 is detected, making it easy to find out whether the pads in the double-block sleeper accessories are missing.

[0089] In this embodiment, after final assembly, the installed double-block sleepers and double-block fine-tuning rail panels 12 are hoisted to the construction site for installation.

[0090] In summary, the present invention is reasonably designed. By installing the double-block sleepers on each sleeper unit at the sleeper distribution station, and adjusting the spacing between each sleeper unit, the spacing of the double-block sleepers can be adjusted, thereby improving the adaptability, reducing labor intensity, improving construction efficiency, and facilitating subsequent assembly with the double-block fine-tuning track panel.

[0091] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
