Description

Technical Field

[0001] This invention relates to the field of rail transit construction technology, and in particular to a track slab laying device and a track slab laying method based on BIM technology. Background Technology

[0002] With the rapid development of rail transit construction, rail transit construction technology has evolved from manual laying to mechanized construction. In rail transit infrastructure construction, the installation and laying of track slabs is a crucial process, and its construction efficiency and quality directly affect the progress and safety of the entire project. To adapt to the ever-increasing demands of rail transit construction, track slab laying technology is continuously developing towards automation and intelligence.

[0003] Currently, the installation of track slabs in rail transit construction mainly relies on manual labor combined with simple mechanical tools. Construction workers need to use transport equipment to move the track slabs to designated locations, transfer them using hoisting equipment, and finally manually adjust and secure them. This construction method depends on a large workforce, has relatively low construction efficiency, and results in high labor intensity for the workers.

[0004] While existing technologies can enable the transfer and installation of track slabs, in actual operation, the difficulty in ensuring construction accuracy and the tendency for manual adjustments to cause deviations can affect the quality of track slab laying. Summary of the Invention

[0005] The main objective of this invention is to propose a track slab laying device and a track slab laying method based on BIM technology. This aims to solve the technical problem that although existing technologies can achieve the transfer and installation of track slabs, in actual operation, the construction accuracy is difficult to guarantee, and manual adjustments are prone to deviations, which affect the laying quality of the track slabs.

[0006] To achieve the above objectives, in a first aspect, the present invention provides a track slab laying device, comprising: A rail transport vehicle, the top of which has a rail plate placement position, and a guide rail is installed on each side along its length. A traveling truss, which is slidably engaged with the two guide rails, extends upward above the placement position, and can travel along the two guide rails; A position adjustment mechanism, mounted on the top of the traveling truss, capable of moving along the width direction of the rail-carrying vehicle from the top of the traveling truss; and... A track slab clamping and laying mechanism is installed on the position adjustment mechanism. The track slab clamping and laying mechanism is used to switch between a clamping and transferring state that adsorbs and clamps the track slab and a laying state that releases and lays the track slab.

[0007] In one embodiment, the position adjustment mechanism includes: The first slide rail is installed on the top of the traveling truss along the width direction of the rail-carrying vehicle; A first sliding travel member, which is slidably engaged with the first slide rail, and the first sliding travel member can travel along the first slide rail; A position measuring component, mounted on top of the first sliding walking member, capable of measuring the placement position of the track plate; and... A connecting beam is provided, which is spaced apart from the position measuring component on the top of the first sliding walking component. One end of the connecting beam extends downward and is connected to the track plate clamping and laying mechanism.

[0008] In one embodiment, the position measurement component includes: An arc-shaped track is installed on the top of the first sliding walking component, and the curvature of the arc-shaped track is perpendicular to the width direction of the rail-carrying vehicle. A second traveling drive component, which slides along the arc-shaped track and is capable of traveling along the arc-shaped track; and... A position measuring component is mounted on the second traveling drive component, which drives the position measuring component to travel along the arc-shaped track so that the position measuring component can measure the placement position of the track plate.

[0009] In one embodiment, the track slab clamping and laying mechanism includes: A connecting frame is installed on the connecting beam, and a first mounting position and a second mounting position are formed on the connecting frame, with the first mounting position and the second mounting position being spaced apart. A clamping assembly, mounted at the first mounting position, the clamping assembly being capable of extending outward along the width direction of the rail-carrying vehicle to clamp the track slab; and... An adsorption assembly is installed at the second installation position and extends downward to adsorb onto the top of the track plate to cooperate with the clamping assembly and clamp and transfer the track plate.

[0010] In one embodiment, the gripping assembly includes: The first horizontal telescopic component has one end connected to the first installation position and the other end extending outward along the width direction of the rail transport vehicle. A first vertical telescopic member, which is installed at the telescopic end of the first horizontal telescopic member; and, A clamping plate is installed at the telescopic end of the first vertical telescopic member. The first horizontal telescopic member can drive the first vertical telescopic member to extend horizontally along the width direction of the rail transport vehicle. When the clamping plate extends out of the rail transport vehicle, the first vertical telescopic member can drive the clamping plate to extend downward to the bottom of the top track plate. The first horizontal telescopic member can also drive the first vertical telescopic member to retract horizontally and clamp the clamping plate at the bottom of the track plate.

[0011] In one embodiment, there are two clamping components, which are spaced apart on the connecting frame along the width direction of the rail transport vehicle, and the two clamping components can clamp the track plate simultaneously.

[0012] In one embodiment, the adsorption components are multiple, and the multiple adsorption components are spaced apart at the bottom of the connecting frame and on both sides of the connecting frame along the length direction of the rail transport vehicle. All the adsorption components can be simultaneously adsorbed onto the top of the track plate or simultaneously detached from the top of the track plate.

[0013] In one embodiment, the adsorption component includes: The second horizontal telescopic member extends along the length direction of the rail transport vehicle; A second vertical telescopic member is mounted at the output end of the second horizontal telescopic member, and extends vertically; and, An adsorption component is installed at the bottom of the second vertical telescopic component. The adsorption component can cooperate with the clamping assembly to adsorb and clamp the track plate, so as to transfer the track plate to the laying position.

[0014] Based on the same technical concept, in a second aspect, the present invention also proposes a track slab laying method based on BIM technology, which applies the track slab laying device described in the first aspect, and the track slab laying device further includes a controller. The BIM-based track slab laying method includes the following steps: The area where the track slab is to be installed is automatically measured, and the coordinate data of the area where the track slab is to be installed is collected. Import the collected coordinate data into the pre-built BIM model; The input coordinate data is compared in the BIM model to determine whether the collected coordinates are accurate. When the collected coordinates are accurate, the accurate coordinate data recorded in the BIM model is transmitted to the controller. The controller controls the track slab clamping and laying mechanism to transfer and install the track slab to be installed based on the received coordinate data.

[0015] In one embodiment, the BIM model contains preset installation coordinate data of the track slab to be installed.

[0016] The technical solution of this invention involves setting up a rail transport vehicle, guide rails, a traveling truss, a position adjustment mechanism, and a track slab clamping and laying mechanism. In use, the rail transport vehicle is first driven to the track slab prefabrication storage area or next to the transport vehicle. The track slab is then manually or with auxiliary equipment placed stably on the rail slab placement position on the rail transport vehicle. At this time, the traveling truss is located at the starting end of the rail transport vehicle, and the position adjustment mechanism moves the track slab clamping and laying mechanism directly above the track slab. The track slab clamping and laying mechanism switches to the clamping and transfer state: the adsorption component is activated, applying uniform negative pressure or magnetic force to the upper surface of the track slab to achieve firm adsorption. Simultaneously, the clamping component closes, further fixing the position of the track slab and preventing shaking or displacement during transfer. Subsequently, the traveling truss moves forward along the guide rail to the laying operation area, and the position adjustment mechanism moves along the width direction at the top of the traveling truss, precisely adjusting the track slab clamping and laying mechanism above the target laying position.

[0017] Upon reaching the designated laying position, the track slab clamping and laying mechanism first slowly lowers its height, bringing the lower surface of the track slab close to the predetermined gap with the roadbed or ballast surface. Then, it releases the suction force of the adsorption components and gradually opens the clamping components, allowing the track slab to be smoothly released and laid in place under gravity. Through this process, the device can automatically transfer, precisely position, and release the track slab, avoiding the frequent manual adjustments required during traditional manual hoisting operations.

[0025] This invention proposes a track slab laying device and a track slab laying method based on BIM technology.

[0026] Please see Figures 1 to 5 For ease of understanding, this track slab laying device includes: The rail transport vehicle 100 has a rail plate placement position formed on its top, and a guide rail 200 is installed on each side of the rail transport vehicle 100 along its length. The traveling truss 300 slides with two guide rails 200. The traveling truss 300 extends upward above the placement position and can travel along the two guide rails 200. A position adjustment mechanism 400 is mounted on the top of the traveling truss 300, and the position adjustment mechanism 400 can travel along the width direction of the rail transport vehicle 100 on the top of the traveling truss 300; and, The track slab clamping and laying mechanism 500 is installed on the position adjustment mechanism 400. The track slab clamping and laying mechanism 500 is used to switch between a clamping and transferring state that adsorbs and clamps the track slab and a laying state that releases and lays the track slab.

[0027] Specifically, the rail-carrying vehicle 100 is arranged along the track direction, with a flat track slab placement area on its top for temporary storage of track slabs to be laid. A straight guide rail 200 is installed on each side of the rail-carrying vehicle 100 along its length, parallel to the length of the vehicle, with a smooth running surface on its upper surface. The traveling truss 300 has a portal frame structure, with roller or slider assemblies on its bottom sides that slide with the two guide rails 200, allowing the traveling truss 300 to move smoothly along the guide rails 200 along the length of the rail-carrying vehicle 100. The vertical portion of the traveling truss 300 extends upwards, spanning above the track slab placement area, forming an overhead working space across the width of the rail-carrying vehicle 100.

[0028] The position adjustment mechanism 400 is mounted on the top crossbeam of the traveling truss 300. The position adjustment mechanism 400 includes a transverse guide rail 200 extending along the width direction of the rail-carrying vehicle 100 and a carriage capable of moving on the transverse guide rail 200. The carriage achieves precise movement along the width direction via a drive device. The track slab clamping and laying mechanism 500 is mounted on the carriage of the position adjustment mechanism 400 and includes an adsorption component 530 and a clamping component 520. The adsorption component 530 uses a vacuum adsorption plate or an electromagnetic adsorption device to reliably adsorb the upper surface of the track slab during clamping and transfer. The clamping component 520 uses openable and closable mechanical grippers to assist in fixing the sides or pre-drilled holes of the track slab.

[0029] In this embodiment, during actual operation, the rail transport vehicle 100 is first driven to the prefabricated track slab storage area or next to the transport vehicle. The track slab is then placed smoothly on the track slab placement position of the rail transport vehicle 100 using manual labor or auxiliary equipment. At this time, the traveling truss 300 is located at the starting end of the rail transport vehicle 100, and the position adjustment mechanism 400 moves the track slab clamping and laying mechanism 500 directly above the track slab. The track slab clamping and laying mechanism 500 switches to the clamping and transfer state: the adsorption component 530 is activated, applying uniform negative pressure or magnetic force to the upper surface of the track slab to achieve firm adsorption; simultaneously, the clamping component 520 closes, further fixing the position of the track slab and preventing shaking or displacement during transfer. Subsequently, the traveling truss 300 moves forward along the guide rail 200 to the laying operation area, and the position adjustment mechanism 400 moves along the width direction at the top of the traveling truss 300, precisely adjusting the track slab clamping and laying mechanism 500 above the target laying position.

[0030] Upon reaching the designated laying position, the track slab clamping and laying mechanism 500 first slowly lowers its height, bringing the lower surface of the track slab close to the predetermined gap with the roadbed or ballast surface. Then, it releases the suction force of the adsorption component 530 and gradually opens the clamping component 520, allowing the track slab to be smoothly released and laid in place under gravity. Through this process, the device can automatically transfer, precisely position, and release the track slab, avoiding the frequent manual adjustments required during traditional manual hoisting operations.

[0031] In one embodiment, the position adjustment mechanism 400 includes: The first slide rail 410 is installed on the top of the traveling truss 300 along the width direction of the rail transport vehicle 100. The first sliding walking component 420 is slidably engaged with the first slide rail 410, and the first sliding walking component 420 can move along the first slide rail 410. A position measuring component 430 is mounted on top of the first sliding travel member 420. The position measuring component 430 can measure the placement position of the track plate; and... A connecting beam 440 is spaced apart from the position measuring component 430 on the top of the first sliding walking component 420. One end of the connecting beam 440 extends downward and is connected to the track plate clamping and laying mechanism 500.

[0032] Specifically, the top of the rail-carrying vehicle 100 forms a track slab placement position, with guide rails 200 installed on both sides. The traveling truss 300 slides and extends upward above the placement position, engaging with the two guide rails 200. The track slab clamping and laying mechanism 500 is installed on the position adjustment mechanism 400. In this embodiment, the top crossbeam of the traveling truss 300 serves as the mounting base for the position adjustment mechanism 400. The first slide rail 410 is fixed to this crossbeam along the width direction, allowing the first sliding traveling member 420 to move laterally in the width direction. The position measuring component 430 is installed on top of the first sliding traveling member 420, enabling precise measurement of the current placement position of the track slab during travel and feeding the measurement data back to the control system to guide the travel distance of the first sliding traveling member 420. The connecting beam 440 is spaced apart from the position measuring component 430, serving to suspend and fix the track slab clamping and laying mechanism 500. Its downward extension ensures that the track slab clamping and laying mechanism 500 is at a suitable working height, facilitating subsequent switching between clamping and laying states.

[0033] In this embodiment, the rail transport vehicle 100 transports the track slab to the work area, and the traveling truss 300 moves along the guide rail 200 to above the track slab placement position. After the position adjustment mechanism 400 is activated, the first sliding traveling component 420 travels along the first slide rail 410, driving the position measuring component 430 on its top to move synchronously. The position measuring component 430 collects the lateral position data of the track slab edge or marked point in real time, calculates the offset by comparing it with the preset laying coordinates, and drives the first sliding traveling component 420 to move precisely to the alignment position. When the first sliding traveling component 420 stops, the connecting beam 440 stably holds the track slab clamping and laying mechanism 500 directly above it. The track slab clamping and laying mechanism 500 then switches to the clamping and transfer state, adsorbing and clamping the track slab. After clamping is completed, the traveling truss 300 continues to move along the length direction, and the position adjustment mechanism 400 further optimizes the lateral alignment accuracy of the track slab at the laying point by fine-tuning the first sliding traveling component 420 along the width direction.

[0034] Through the sliding engagement of the first slide rail 410 and the first sliding walking component 420, combined with the real-time measurement function of the position measuring component 430, and the reliable connection of the connecting beam 440 to the track slab clamping and laying mechanism 500, the automated and precise adjustment of the track slab in the width direction is achieved. During the structural implementation, the first slide rail 410 provides a rigid guide path for lateral movement, along which the first sliding walking component 420 moves smoothly, avoiding the swaying caused by the lack of guide rail 200 constraint in traditional hoisting equipment; the position measuring component 430 is installed on the top of the first sliding walking component 420, which can directly obtain the actual data of the track slab placement position during movement and reduce positioning deviation through closed-loop control; the connecting beam 440 and the position measuring component 430 are distributed at intervals on the top of the first sliding walking component 420, which not only avoids mutual interference between the measuring component and the connecting beam 440, but also directly links the movement of the clamping and laying mechanism with the movement of the first sliding walking component 420 through the downward extension, ensuring that the lateral adjustment action is directly transmitted to the track slab.

[0035] In one embodiment, the position measurement component 430 includes: The curved track 431 is installed on the top of the first sliding walking component 420, and the curvature direction of the curved track 431 is perpendicular to the width direction of the rail transport vehicle 100. The second travel drive component 432 is slidably engaged with the arc-shaped track 431, and the second travel drive component 432 can travel along the arc-shaped track 431; and, The position measuring component 433 is installed on the second travel drive component 432. The second travel drive component 432 can drive the position measuring component 433 to travel along the arc track 431 so that the position measuring component 433 can measure the placement position of the track plate.

[0036] Specifically, the first sliding walking component 420 serves as the mounting carrier for the position measuring component 430, with the arc-shaped track 431 fixed on its top, enabling the second walking drive component 432 to move on the arc-shaped path. The position measuring component 433 moves synchronously with the second walking drive component 432, realizing dynamic scanning measurement of the edge of the track plate or the marked point.

[0037] In this embodiment, after the position measurement component 430 is activated, the second walking drive component 432 drives the position measurement component 433 to move along the arc-shaped track 431. The position measurement component 433 sequentially collects distance data or angle data of the track slab placement position at different positions along the arc path. By comparing the multi-point measurement results with the preset laying coordinates, the lateral offset and possible posture deviation are calculated and fed back to the control system to drive the first sliding walking component 420 for compensation and adjustment. Subsequently, the connecting beam 440 holds the track slab clamping and laying mechanism 500 in the optimized position directly above it, and the track slab clamping and laying mechanism 500 switches to the clamping and transfer state to adsorb and clamp the track slab.

[0038] Through the sliding engagement of the arc-shaped track 431 and the second traveling drive component 432, and the movement of the position measuring component 433 along the arc-shaped path, multi-point precise measurement of the track slab placement position is achieved. During the structural implementation, the arc-shaped track 431 provides a stable arc-shaped guide path for the second traveling drive component 432, avoiding the limitation of a single viewpoint that may occur during straight-line measurement. When the second traveling drive component 432 moves along the arc-shaped track 431, it drives the position measuring component 433 to collect data at different arc points, forming a measurement dataset covering a certain angle range. The position measuring component 433 is installed on the second traveling drive component 432, and its measurement results are directly related to the lateral adjustment action of the first sliding traveling component 420, ensuring the final positioning accuracy of the track slab clamping and laying mechanism 500.

[0039] In another embodiment, the arc-shaped track 431 can adopt a semi-circular or fan-shaped arc structure, with its radius of curvature adapted according to the track plate specifications, and is installed at the center of the top of the first sliding walking component 420; the second walking drive component 432 is correspondingly configured as a servo motor driven gear-rack engagement or synchronous belt drive to achieve precise step-by-step movement along the arc-shaped track 431. The position measuring component 433 can adopt a combination of a laser rangefinder and an inclination sensor, wherein the laser rangefinder is used for real-time distance measurement, and the inclination sensor assists in recording the changes in posture angle during the arc-shaped walking process. In this embodiment, the second walking drive component 432 first drives the position measuring component 433 to start walking from one end of the arc track 431 and complete the full arc scan to the other end. The laser rangefinder collects the distance values ​​of multiple reference points on the upper surface of the track slab at multiple discrete arc points, and the tilt sensor synchronously records the tilt data of each point. The lateral coordinates and attitude correction of the track slab placement position are calculated and generated. The first sliding walking component 420 performs width direction compensation based on the comprehensive data, and the connecting beam 440 then stably transmits the adjusted position to the track slab clamping and laying mechanism 500.

[0040] In one embodiment, the track slab clamping and laying mechanism 500 includes: A connecting frame 510 is installed on a connecting beam 440. A first mounting position and a second mounting position are formed on the connecting frame 510, and the first mounting position and the second mounting position are spaced apart. A clamping assembly 520 is installed at a first mounting position. The clamping assembly 520 can extend outward along the width direction of the rail transport vehicle 100 and clamp the rail plate; and, Adsorption assembly 530 is installed in a second installation position. Adsorption assembly 530 can extend downward to adsorb onto the top of the track plate so as to cooperate with clamping assembly 520 and clamp the transfer track plate.

[0041] Specifically, the lower end of the connecting beam 440 serves as the installation interface for the track slab clamping and laying mechanism 500. The connecting frame 510 is fixed to the lower end of the connecting beam 440, so that the first installation position and the second installation position respectively bear the clamping component 520 and the adsorption component 530, thereby achieving the coordinated arrangement of the two in space.

[0042] In this embodiment, the connecting beam 440 stably holds the connecting frame 510 directly above the track slab. The track slab clamping and laying mechanism 500 switches to the clamping and transferring state: the lifting rod of the adsorption component 530 extends downward, and multiple adsorption units contact and adsorb onto the top surface of the track slab, forming a uniform negative pressure or magnetic fixation; simultaneously, the telescopic arm of the clamping component 520 extends outward along the width direction, and its mechanical grippers close to clamp the side of the track slab, further assisting in fixation. Subsequently, the position adjustment mechanism 400 and the traveling truss 300 move in coordination to transfer the track slab above the laying point. After reaching the laying position, the track slab clamping and laying mechanism 500 switches to the laying state: the adsorption component 530 gradually releases the adsorption force, the lifting rod slowly rises, and the telescopic arm of the clamping component 520 retracts and opens the mechanical grippers, allowing the track slab to be smoothly released and laid in place under the action of gravity.

[0043] By spaced apart at the first and second mounting positions on the connecting frame 510, and combined with the outward extending gripping action of the clamping component 520 along the width direction, and the downward adsorption component 530 extending to the top of the track plate for adsorption, stable clamping, transfer, and precise release of the track plate are achieved. During structural implementation, the connecting frame 510 provides a rigid mounting base for the clamping component 520 and the adsorption component 530, ensuring their relative positions are fixed and preventing relative misalignment during transfer. The clamping component 520, installed at the first mounting position, reliably clamps the side of the track plate when its telescopic arm extends outward, compensating for any potential localized insufficient adsorption by the adsorption component 530. The adsorption component 530, installed at the second mounting position, has a downward extending lifting rod that allows the adsorption unit to directly act on the top of the track plate, forming a large-area contact adsorption. Together with the clamping component 520, this constitutes a dual fixing method, significantly enhancing the anti-shaking and anti-displacement capabilities during transfer.

[0044] In another embodiment, the connecting frame 510 can adopt an adjustable-spacing frame structure, and the interval between the first installation position and the second installation position can be adapted and adjusted according to the width of the track plate; the clamping component 520 can adopt a hydraulic or pneumatically driven parallel opening and closing gripper, and its telescopic arm is configured as a multi-section telescopic structure, with an outward extension stroke of more than one-third of the width of the track plate. A rubber buffer pad is added to the end of the gripper to protect the edge of the track plate; the adsorption component 530 can adopt a hybrid form of vacuum adsorption cup combined with electromagnetic adsorption unit, and the lifting rod is a precision lifting structure driven by a screw, with multiple evenly distributed suction cup units at the lower end, each suction cup unit equipped with an independent vacuum control valve. In this embodiment, after the connecting frame 510 is installed on the connecting beam 440, the interval between the first installation position and the second installation position is adjusted according to the specifications of the track plate. In the clamping and transfer state, the lifting rod of the adsorption component 530 descends rapidly, the hybrid adsorption unit is activated at the same time to form a composite adsorption force, and the telescopic arm of the clamping component 520 then extends outward, the parallel opening and closing jaws close and apply auxiliary clamping force. After the transfer is completed, when switching the laying state, the vacuum and electromagnetic adsorption are gradually released first, and then the telescopic arm is slowly retracted and the jaws are opened to ensure that the track plate falls evenly and avoid tilting caused by unilateral force.

[0045] In one embodiment, the gripping component 520 includes: The first horizontal telescopic component 521 has one end connected to the first installation position and the other end extending outward along the width direction of the rail transport vehicle 100. The first vertical telescopic member 522 is installed at the telescopic end of the first horizontal telescopic member 521; and, The clamping plate 523 is installed at the telescopic end of the first vertical telescopic member 522. The first horizontal telescopic member 521 can drive the first vertical telescopic member 522 to extend horizontally along the width direction of the rail transport vehicle 100. When the clamping plate 523 extends out of the rail transport vehicle 100, the first vertical telescopic member 522 can drive the clamping plate 523 to extend downward to the bottom of the top track plate. The first horizontal telescopic member 521 can drive the first vertical telescopic member 522 to retract horizontally and clamp the clamping plate 523 at the bottom of the track plate.

[0046] Specifically, one end of the first horizontal telescopic member 521 is fixed to the first installation position of the connecting frame 510, and its telescopic end carries the first vertical telescopic member 522 and the clamping plate 523, so that the clamping assembly 520 can extend along the width direction and clamp from below the side of the track plate.

[0047] In this embodiment, when the track slab clamping and laying mechanism 500 switches to the clamping and transferring state, the adsorption component 530 first extends downward and adsorbs onto the top surface of the track slab, forming a preliminary fixation. Subsequently, the first horizontal telescopic member 521 drives the first vertical telescopic member 522 to extend horizontally along the width direction, causing the clamping plate 523 to extend from the side of the track slab to its outside. Next, the first vertical telescopic member 522 drives the clamping plate 523 to extend downward to the bottom of the track slab located at the top, and the supporting surface of the upper surface of the clamping plate 523 contacts and supports the bottom of the track slab. Finally, the first horizontal telescopic member 521 drives the first vertical telescopic member 522 to retract horizontally, causing the clamping plate 523 to clamp inward from the bottom of the track slab, stably clamping the bottom edge of the track slab between the clamping plate 523 and the adsorption component 530. After clamping is completed, the traveling truss 300 and the position adjustment mechanism 400 move together to transfer the track slab above the laying point. When switching between laying states, the adsorption force of the adsorption component 530 is gradually released first, and then the clamping plate 523 is slowly lifted by the first vertical telescopic component 522, and the first horizontal telescopic component 521 retracts, so that the track plate is smoothly released and laid in place under the action of gravity.

[0048] The horizontal extension of the first horizontal telescopic member 521 along the width direction, combined with the vertical extension of the first vertical telescopic member 522 onto the clamping plate 523, and the clamping action of the clamping plate 523 at the bottom of the track slab, enables reliable clamping and transfer of the bottom of the track slab. During structural implementation, one end of the first horizontal telescopic member 521 is connected to the first installation position. Its outward extension allows the first vertical telescopic member 522 and the clamping plate 523 to cross the side of the track plate and reach the outside, avoiding potential collisions caused by direct insertion from above. The first vertical telescopic member 522 is installed at the telescopic end of the first horizontal telescopic member 521. When the clamping plate 523 extends out of the track vehicle, it drives the clamping plate 523 downward to the bottom of the track plate, forming a clamping path supported from below. The clamping plate 523 is installed at the telescopic end of the first vertical telescopic member 522. Its flat supporting surface and guide slope ensure that the clamping plate 523 fits tightly against the bottom of the track plate during retraction, ensuring uniform distribution of clamping force. Together with the adsorption component 530, it forms a coordinated upper and lower fixing method, significantly enhancing the anti-sway capability and posture stability during the transfer process.

[0049] In another embodiment, the first horizontal telescopic member 521 can adopt a hydraulic drive structure with two cylinders in parallel, and its telescopic stroke can be adapted and adjusted according to the width of the track plate. The first vertical telescopic member 522 is correspondingly configured as a multi-stage telescopic cylinder, and the clamping plate 523 can adopt two symmetrically distributed clamping plate units 523. Each clamping plate unit 523 is connected by an independent vertical telescopic member to achieve symmetrical clamping of the bottom sides of the track plate. In this embodiment, in the clamping and transfer state, the first horizontal telescopic member 521 first drives the first vertical telescopic member 522 to extend horizontally to the outside of the side of the track plate; the first vertical telescopic member 522 then drives the clamping plate unit 523 to extend downward to the bottom of the track plate, and the two clamping plate units 523 move downward synchronously so that their supporting surfaces contact the bottom sides of the track plate respectively; then, the first horizontal telescopic member 521 drives the first vertical telescopic member 522 to retract horizontally, so that the two clamping plate units 523 tighten inward, stably clamping the bottom of the track plate therein, and forming a three-point or multi-point fixation in conjunction with the adsorption component 530. When switching between laying states, the adsorption force of the adsorption component 530 is first released, and then the clamping plate 523 unit is gradually lifted by the first vertical telescopic component 522, and the first horizontal telescopic component 521 retracts, so that the track plate falls evenly.

[0050] In one embodiment, there are two clamping components 520, which are distributed at intervals along the width direction of the rail transport vehicle 100 on the connecting frame 510, and the two clamping components 520 can clamp the track plate synchronously.

[0051] In this embodiment, when the track slab clamping and laying mechanism 500 switches to the clamping and transfer state, the adsorption component 530 first extends downward and adsorbs onto the top surface of the track slab, providing initial fixing force. Subsequently, the two clamping components 520 are activated simultaneously: the first horizontal telescopic member 521 of each clamping component 520 drives the first vertical telescopic member 522 to extend horizontally along the width direction, so that their respective clamping plates 523 extend from the corresponding side of the track slab to the outside. Next, each first vertical telescopic member 522 simultaneously drives the clamping plate 523 to extend downward to the bottom of the track slab, and the supporting surface of the clamping plate 523 contacts and supports the bottom edges of the track slab on both sides. Finally, the two first horizontal telescopic members 521 simultaneously drive the first vertical telescopic member 522 to retract horizontally, so that the clamping plates 523 on both sides clamp inward from the bottom of the track slab, stably clamping the bottom edges of the track slab between the clamping plates 523 and the adsorption component 530, forming three-point or multi-point fixation. After clamping is completed, the traveling truss 300 moves longitudinally, and the position adjustment mechanism 400 makes necessary fine adjustments to transfer the track slab above the laying point. When switching the laying state, the adsorption force of the adsorption component 530 is gradually released first, and then the clamping plate 523 is lifted slowly and synchronously through the two first vertical telescopic members 522, while the first horizontal telescopic member 521 retracts synchronously, so that the track slab is evenly released and laid in place under the action of gravity.

[0052] Two clamping components 520 are spaced apart along the width of the connecting frame 510 and perform synchronous clamping actions. Combined with the adsorption component 530, this achieves symmetrical fixation of the track slab's bottom on both sides during the transfer process. During structural implementation, the two clamping components 520 are spaced apart on the connecting frame 510, ensuring that the first horizontal telescopic member 521 of each clamping component 520 can extend independently but synchronously to the corresponding side, avoiding eccentric loading that might be caused by unilateral clamping. The first vertical telescopic member 522 of each clamping component 520 drives the clamping plate 523 downwards to the bottom of the track slab after the clamping plate 523 extends out of the rail transport vehicle 100, forming a symmetrical support path from below. During synchronous retraction, the clamping plate 523 applies balanced clamping force to the bottom edge of the track slab on both sides, forming a stable triangular or polygonal fixing system together with the centrally located adsorption component 530. This significantly enhances the anti-sway, anti-torsion, and attitude maintenance capabilities during long-distance transfer.

[0053] In another embodiment, the spacing between the two clamping components 520 can be adapted and adjusted according to the width of different specification track plates. The connecting frame 510 is correspondingly provided with a movable mounting base, so that the first mounting position of each clamping component 520 can be finely adjusted in the width direction. The first horizontal telescopic member 521 of each clamping component 520 can be in the form of a ball screw driven by a servo motor to achieve higher synchronization accuracy and displacement control. The first vertical telescopic member 522 can be configured as an electric cylinder with position feedback. A pressure sensor is added to the surface of the clamping plate 523 to monitor the clamping force in real time and feed it back to the control unit. In this embodiment, during the clamping and transfer state, the two clamping components 520 first adjust the spacing according to the width of the track plate and align with the side position; after the adsorption component 530 adsorbs, the first horizontal telescopic members 521 on both sides extend synchronously, and the first vertical telescopic members 522 synchronously drive the clamping plate 523 downward to the bottom; the pressure sensor monitors the clamping force on both sides during the retraction clamping stage to ensure that the values ​​are balanced; after the transfer is completed, in the laying state, the control unit synchronously controls the lifting and retraction actions according to the sensor data, so that the track plate is smoothly released.

[0054] In one embodiment, there are multiple adsorption components 530, which are spaced apart at the bottom of the connecting frame 510 and on both sides of the connecting frame 510 along the length of the rail transport vehicle 100. All adsorption components 530 can be simultaneously adsorbed onto the top of the track plate or simultaneously detached from the top of the track plate.

[0055] Specifically, multiple adsorption components 530 are respectively disposed in the central area at the bottom of the connecting frame 510 and on the front and rear edges of the connecting frame 510 along the length of the rail carrier 100. Each adsorption component 530 includes a downwardly extending lifting rod and a vacuum adsorption plate or electromagnetic adsorption unit disposed at the lower end of the lifting rod. The specifications and spacing of each adsorption unit are matched according to the characteristics of the top surface of the track slab. All adsorption components 530 are synchronized through the same control unit to ensure that the extension of the lifting rod, the application of the adsorption force, and the retraction and detachment processes are consistent in time and displacement.

[0056] The bottom and both sides of the connecting frame 510 serve as mounting carriers for multiple adsorption components 530. Their spacing allows the adsorption units to cover the top center and front and rear edge areas of the track plate, forming a multi-point coordinated fixing layout with the clamping components 520 on both sides.

[0057] Precise alignment in the width direction is achieved through the first sliding walking component 420 and the position measuring component 430, and the connecting beam 440 stably holds the connecting frame 510 directly above the track slab. When the track slab clamping and laying mechanism 500 switches to the clamping and transferring state, all adsorption components 530 are activated simultaneously: the lifting rod of each adsorption component 530 extends downward, so that its adsorption unit contacts the top surface of the track slab; then adsorption force is applied simultaneously to form a uniform negative pressure or magnetic fixation; then the two clamping components 520 move simultaneously to clamp from both sides of the bottom of the track slab, forming a multi-point fixing system together with the multiple adsorption components 530. After clamping is completed, the walking truss 300 moves longitudinally, and the position adjustment mechanism 400 makes necessary fine adjustments to transfer the track slab above the laying point. When switching between laying states, all adsorption components 530 are simultaneously detached from the top of the track slab: first, the adsorption force is released simultaneously, and then the lifting rod is raised simultaneously, so that the adsorption unit gradually leaves the top surface of the track slab. At the same time, the two clamping components 520 are raised and retracted simultaneously, so that the track slab is evenly released and laid in place under the action of gravity.

[0058] In another embodiment, the number and spacing of the plurality of adsorption components 530 can be adapted and adjusted according to the length and width of track plates of different specifications. The connecting frame 510 is correspondingly provided with movable mounting supports, so that the position of each adsorption component 530 can be finely adjusted at the bottom and on both sides of the length direction. The lifting rod of each adsorption component 530 can be driven by an electric screw with position feedback to achieve higher synchronization accuracy and height control. The adsorption unit can be configured as a hybrid form of vacuum adsorption plate combined with electromagnetic adsorption unit, and a pressure sensor is added to the lower surface to monitor the adsorption force in real time and feed it back to the control unit. In this embodiment, in the clamping and transfer state, the plurality of adsorption components 530 first adjust the spacing according to the size of the track plate and align with the corresponding area on the top; all lifting rods descend synchronously, the hybrid adsorption unit starts at the same time to form a composite adsorption force, and the pressure sensor monitors the adsorption force at each point to ensure that the value is balanced; after the clamping components 520 move synchronously, the control unit dynamically fine-tunes the adsorption force according to the sensor data during the transfer process; when the laying state is switched, all adsorption components 530 release the adsorption force synchronously and raise the lifting rods, combined with the synchronous movement of the clamping components 520, so that the track plate is smoothly detached. This other embodiment further supports the higher-level generalization of the number, distribution location and synchronization characteristics of the adsorption components 530 in the claims, and broadens the adaptability of the device to various track plate specifications and complex working environments through adjustable intervals and drive and monitoring forms with feedback.

[0059] In one embodiment, the adsorption component 530 includes: The second horizontal telescopic component 531 extends along the length direction of the rail transport vehicle 100. The second vertical telescopic member 532 is installed at the output end of the second horizontal telescopic member 531, and extends vertically; and, The adsorption component 533 is installed at the bottom of the second vertical telescopic component 532. The adsorption component 533 can cooperate with the clamping component 520 to adsorb and clamp the track plate, so as to transfer the track plate to the laying position.

[0060] Specifically, one end of the second horizontal telescopic member 531 is connected to the area corresponding to the second installation position of the connecting frame 510, and its output end carries the second vertical telescopic member 532 and the adsorption member 533, so that the adsorption assembly 530 can adjust its position in the length direction and form a cooperative layout with the clamping assemblies 520 on both sides in the length direction.

[0061] In this embodiment, when the track slab clamping and laying mechanism 500 switches to the clamping and transferring state, all adsorption components 530 are activated simultaneously: the second horizontal telescopic member 531 of each adsorption component 530 first extends along the length direction, causing the output end to drive the second vertical telescopic member 532 and the adsorption member 533 to reach above the corresponding area on the top of the track slab; then the second vertical telescopic member 532 drives the adsorption member 533 to extend downward until the lower surface of the adsorption member 533 contacts the top surface of the track slab; then adsorption force is applied simultaneously to form a uniform fixation. At the same time, two clamping components 520 clamp from the bottom of the track slab simultaneously, forming a multi-point cooperative fixation together with multiple adsorption components 530. After clamping is completed, the traveling truss 300 moves longitudinally, and the position adjustment mechanism 400 makes necessary fine adjustments to transfer the track slab above the laying point. When switching between laying states, all adsorption components 530 are released simultaneously: first, the adsorption force is released simultaneously, then the adsorption component 533 is raised simultaneously through the second vertical telescopic component 532, and the second horizontal telescopic component 531 is retracted simultaneously, so that the adsorption component 533 gradually leaves the top surface of the track slab. At the same time, the clamping component 520 is raised and retracted simultaneously, so that the track slab is evenly released and laid in place under the action of gravity.

[0062] By extending the second horizontal telescopic member 531 along its length, combined with the vertical drive of the adsorption member 533 by the second vertical telescopic member 532, and the adsorption clamping action of the adsorption member 533 with the clamping assembly 520, the track plate can be fixed and transferred at multiple positions along its length. During implementation, the second horizontal telescopic member 531 extends along its length, allowing the second vertical telescopic member 532 and the adsorption member 533 to move precisely to the front and rear areas of the top of the track plate, avoiding insufficient coverage that might result from fixed-position adsorption. The second vertical telescopic member 532 is installed at the output end of the second horizontal telescopic member 531, driving the adsorption member 533 downwards to the top of the track plate after it reaches the top, forming a reliable contact path. The adsorption member 533 is installed at the bottom of the second vertical telescopic member 532, its flat adsorption surface tightly adhering to the top of the track plate during synchronous force application, forming a bidirectional balanced fixing system with the clamping assembly 520 in the width direction, significantly enhancing the resistance to forward and backward swaying, torsion, and overall posture maintenance during the transfer process.

[0063] In another embodiment, the second horizontal telescopic member 531 may adopt a multi-section hydraulic cylinder parallel structure, and its telescopic stroke is adapted and adjusted according to the length of the track plate. The second vertical telescopic member 532 is correspondingly configured as an electric screw with position feedback. The adsorption member 533 may adopt a hybrid array of vacuum adsorption disk and electromagnetic adsorption unit. Each adsorption member 533 unit is equipped with an independent pressure sensor for real-time monitoring of contact force and adsorption force and feedback to the control unit. In this embodiment, during the clamping and transfer state, multiple adsorption components 530 first extend synchronously along the length direction to the corresponding areas before and after the track plate via the second horizontal telescopic member 531; the second vertical telescopic member 532 synchronously drives the adsorption member 533 downward to contact the top surface, the mixed adsorption unit is activated to form a composite adsorption force, and the pressure sensor monitors the values ​​at each point to ensure balance; after the clamping components 520 move synchronously, the control unit dynamically adjusts the telescopic position and adsorption force according to the sensor data during the transfer process; when the laying state is switched, all adsorption components 530 synchronously release the adsorption force, the second vertical telescopic member 532 raises the adsorption member 533, the second horizontal telescopic member 531 retracts synchronously, and combined with the synchronous movement of the clamping components 520, the track plate is smoothly detached.

[0064] Based on the same technical concept, in a second aspect, the present invention also proposes a track slab laying method based on BIM technology, which applies the track slab laying device of the first aspect, and the track slab laying device further includes a controller. The track slab laying method based on BIM technology includes the following steps: S100: Automatically measure the area where the track slab is to be installed and collect the coordinate data of the area where the track slab is to be installed; S200. Import the collected coordinate data into the pre-built BIM model; S300. Compare the input coordinate data in the BIM model to determine whether the collected coordinates are accurate. S400: When the collected coordinates are accurate, transmit the accurate coordinate data recorded in the BIM model to the controller. The S500 controller controls the track slab clamping and laying mechanism to transfer and install the track slabs to be installed based on the received coordinate data.

[0065] Specifically, the controller is electrically connected to the position measurement component, the walking drive component, the first sliding walking component, the second walking drive component, the first horizontal telescopic component, the first vertical telescopic component, the second horizontal telescopic component, the second vertical telescopic component, and the drive part of the adsorption unit to form a closed-loop control circuit, so that the coordinate data output by the BIM model can be directly converted into the precise action parameters of each telescopic component and drive component.

[0066] The location measurement component automatically scans and measures the area where the track slabs are to be installed, collecting 3D coordinate data of multiple feature points in the area and uploading it in real time. The collected coordinate data is then imported into a pre-built BIM model, where coordinate comparison calculations are performed to determine if the deviation between the actual measured values ​​and the model's baseline values ​​is within acceptable limits. When the comparison results show accurate coordinates, the BIM model transmits the accurate coordinate data to the controller. Upon receiving the coordinate data, the controller generates control signals containing the movement path of the traveling truss, alignment instructions for the position adjustment mechanism, and the action sequence of the track slab clamping and laying mechanism. The track slab clamping and laying mechanism then... The system first moves to a position above the track slab. Multiple adsorption components of the adsorption assembly extend along the length direction via the second horizontal telescopic component and are driven downward by the second vertical telescopic component to achieve synchronous adsorption. The two first horizontal telescopic components of the clamping assembly extend along the width direction and the first vertical telescopic component drives the clamping plate downward to the bottom and retracts synchronously to achieve clamping, forming multi-point fixation. Subsequently, the traveling truss and the position adjustment mechanism move in coordination to transfer the track slab above the area to be installed, and perform fine-tuning of its attitude according to the precise coordinates output by the controller. Finally, the adsorption assembly synchronously releases the adsorption force and rises, and the clamping assembly synchronously lifts and retracts, allowing the track slab to be smoothly installed in place under the action of gravity.

[0067] The system automatically measures and collects coordinate data of the installation area, imports it into the BIM model for comparison to confirm accuracy, and transmits the accurate coordinates to the controller to control the track slab clamping and laying mechanism to complete the transportation and installation work, realizing a data-driven process from measurement to installation. During structural implementation, the automatic measurement step directly obtains the coordinates of the area to be installed through the measuring elements of the position measurement component, avoiding the subjective errors of manual measurement; the coordinate data is imported into the BIM model and compared to ensure the consistency between the actual position and the design benchmark, and prompts for remeasurement when the deviation exceeds the threshold; the controller generates drive commands based on the accurate coordinates, precisely controlling the movement of the traveling truss along the guide rail, the position adjustment mechanism to complete the lateral and arc adjustment through the first sliding traveling component and the second traveling drive component, and the track slab clamping and laying mechanism to achieve bottom clamping through the sequential action of the first horizontal telescopic component and the first vertical telescopic component, and to achieve top adsorption through the cooperation of the second horizontal telescopic component and the second vertical telescopic component, so that the track slab transportation path and installation landing point strictly follow the BIM coordinate data, significantly enhancing the positioning accuracy and action coordination of the entire operation process.

[0068] In another embodiment, in the BIM-based track slab laying method, the automatic measurement step can use a laser scanner or total station as the measuring element of the position measurement component to collect dense point cloud coordinate data of the area to be installed; the BIM model comparison process adds a real-time deviation visualization display module, which automatically transmits accurate data when the coordinate deviation is within the threshold, and triggers an alarm and suggests local remeasurement when the deviation is large; after receiving the coordinate data, the controller not only controls the movement of the track slab clamping and laying mechanism, but also synchronously links the walking drive system of the track transport vehicle to realize continuous path planning from the placement position to the installation position; the synchronous movement of the clamping component and the adsorption component is further refined by the timing control algorithm built into the controller, and the displacement and speed of the telescopic component at each step are dynamically adjusted according to the weight of the track slab and the BIM coordinates. In this embodiment, the workflow first completes the point cloud data acquisition and imports it into the BIM model for comparison and confirmation; the controller generates a sequence of instructions including speed curves and attitude maintenance parameters; multiple adsorption components of the adsorption assembly complete top fixation through the synchronous action of the second horizontal telescopic component and the second vertical telescopic component, and the clamping component completes bottom clamping through the synchronous action of the first horizontal telescopic component and the first vertical telescopic component; during the transfer process, the controller fine-tunes the walking truss and position adjustment mechanism according to real-time coordinate feedback; during installation, the controller directs all telescopic components to retract in a preset sequence so that the track plate is accurately placed at the BIM coordinate point.

[0069] In one embodiment, the BIM model contains preset installation coordinate data of the track slab to be installed.

[0070] In this embodiment, by pre-embedding the preset installation coordinate data of the track slabs to be installed into the BIM model, combined with automatic measurement to collect actual coordinates, model comparison to confirm accuracy, and the controller controlling the track slab clamping and laying mechanism to complete the transfer and installation operations based on accurate coordinates, rapid matching and automated execution of measurement data with design benchmarks are achieved. During structural implementation, the embedding of preset installation coordinate data in the BIM model provides a stable benchmark for the comparison step, avoiding errors that may be introduced by temporary input benchmarks; after the actual coordinate data collected by the position measurement component is imported into the model, it is precisely calculated with the preset coordinates to ensure that the coordinates transmitted to the controller strictly correspond to the engineering design requirements; the controller generates drive commands based on the preset installation coordinates to precisely control the clamping action in the width direction of the first horizontal telescopic component and the first vertical telescopic component, the adsorption action in the length direction of the second horizontal telescopic component and the second vertical telescopic component, and the movement path of the traveling truss and the position adjustment mechanism, so that the track slab transfer landing point is highly consistent with the preset coordinates, significantly enhancing the positioning consistency and action repeatability of the entire operation process.

[0071] In another embodiment, the preset installation coordinate data embedded in the BIM model can be further subdivided into segmented coordinate groups of each edge feature point of the track slab, and associated with track slab specification parameters and laying slope correction values; a dynamic weighting algorithm is added to the comparison process, giving higher weight to elevation coordinates to adapt to slight changes in terrain; after receiving accurate coordinates, the controller not only controls the extension and retraction of the track slab clamping and laying mechanism, but also links the position measurement component to perform real-time verification scanning, and inserts intermediate verification points in the transport path. When the deviation between the real-time coordinates and the preset coordinates exceeds a threshold, an attitude correction command is automatically triggered. In this embodiment, the workflow first completes the actual coordinate acquisition and imports it into the BIM model, and performs a weighted comparison and confirmation with the embedded preset coordinate group; the controller generates a command sequence containing intermediate verification parameters; the adsorption component and the clamping component synchronously complete top adsorption and bottom clamping according to the preset coordinates; during the transport process, the controller fine-tunes the walking truss and position adjustment mechanism according to real-time feedback; during installation, all telescopic components retract according to a preset timing sequence, so that the track slab is accurately placed at the preset coordinate point.

[0072] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of the present invention.
