Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and more specifically, to a novel separating, lifting, and transferring device. Background Technology

[0002] With the rapid development of the automotive industry, vehicle manufacturers are comprehensively upgrading and transforming their production lines to automation. As a core process in vehicle manufacturing, the chassis assembly line is mainly responsible for key functions such as automatic assembly of the chassis and body, automatic bolt tightening, and automatic separation of the body from the pallet.

[0003] Traditional automated chassis separation processes typically employ a step-by-step operation: first, the chassis is lifted and separated at a first station, then the pallet is transported to a second station for transfer and return. However, this existing operation mode has the following technical drawbacks: First, the lifting mechanism and the transfer mechanism are set up as two independent workstations, resulting in a large overall structure of the equipment, occupying a large amount of factory floor space, and easily causing tight workshop workstation layout. Second, the switching between workstations increases ineffective conveying strokes and equipment waiting time, resulting in redundant process connections and thus forming a bottleneck in production cycle. Finally, the existing single workstation functions are too simple and cannot meet the needs of automated production with multiple processes, which seriously restricts the further improvement of vehicle production capacity.

[0004] Therefore, it is necessary to propose a new type of separation lifting and transfer device to at least partially solve the problems existing in the prior art. Summary of the Invention

[0005] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section.

[0006] To at least partially solve the above problems, the present invention provides a novel separating lifting and transferring device, comprising: The transfer track is set on the ground; The transfer frame is slidably mounted on the transfer track, and its bottom is provided with a lateral drive device for driving it to move laterally along the transfer track; The lifting platform assembly is vertically and flexibly mounted above the moving frame; A conveying assembly, installed on top of the lifting platform assembly, is used to carry and convey materials; An anti-sway component is connected between the moving frame and the lifting platform assembly. The anti-sway component includes a vertically arranged guide member for constraining the horizontal degree of freedom of the lifting platform assembly relative to the moving frame. A track alignment component, located on one side of the transfer frame, is used to lock the conveying component to a preset separation station.

[0007] Preferably, the novel separation lifting and moving device further includes a drive component; the drive component is inclinedly disposed between the moving frame and the lifting platform component, and is used to drive the lifting platform component to perform lifting and lowering actions relative to the moving frame.

[0008] Preferably, the guide member includes two parallel and vertically connected I-beam columns to one side of the moving frame; the side of the lifting platform assembly is connected to two sets of symmetrically arranged support brackets, the end of each set of support brackets extends to the corresponding I-beam column, and a rolling guide is installed that rolls against the side wall of the I-beam column.

[0009] Preferably, the rolling guide includes at least two pairs of rollers, and vertical guide grooves are formed on opposite sides of the two I-beam columns. The two pairs of rollers are respectively rolled in the vertical guide grooves of the two I-beam columns. The rollers are used to limit the horizontal lateral movement of the lifting platform assembly during lifting.

[0010] Preferably, the track alignment assembly includes: A fixed frame is installed on the ground on one side of the transfer track, and a supporting structure is provided on its top; The movable frame is installed on the rear end face of the lifting platform assembly and moves up, down and sideways synchronously with the lifting platform assembly. When the moving frame is reset and the lifting platform assembly rises to the preset high working point, the movable frame is mechanically locked and docked with the fixed frame through the docking structure.

[0011] Preferably, the docking structure includes: A limiting plate is symmetrically arranged on the top of the fixing frame and has a locking groove, with an opening on one side of the locking groove; The movable docking assembly includes a drive motor, a rotating plate, connecting rods, a swing arm, and a locking bearing wheel. The drive motor is mounted at the center of the movable frame, and the rotating plate is connected to its output shaft. A connecting rod is hinged to each end of the rotating plate. The swing arms are hinged to both sides of the movable frame, and the locking bearing wheel is connected to the swing arm. The other end of the connecting rod is hinged to the swing arm. When the lifting platform assembly rises to its position, the locking bearing wheel locks into the locking groove to perform docking.

[0012] Preferably, a scissor support mechanism is further connected between the bottom of the lifting platform assembly and the moving frame; the output end of the drive assembly acts on the bottom of the lifting platform assembly or the cross axis of the scissor support mechanism; the drive assembly is a hydraulic cylinder, the bottom end of the cylinder barrel of the hydraulic cylinder is hinged to the base of the moving frame, and the top end of its piston rod extends obliquely upward and is hinged to the lifting platform assembly. A bellows cover is also provided between the lifting platform assembly and the moving frame. The upper edge of the bellows cover is connected to the lifting platform assembly, and the lower edge is connected to the moving frame. The hydraulic cylinder and the scissor support mechanism are both enclosed in the inner cavity of the bellows cover.

[0013] Preferably, the conveying assembly is configured as a motorized roller bed assembly, including a plurality of parallel conveying rollers and a roller bed drive motor for driving the conveying rollers to rotate. The conveying direction of the conveying rollers is perpendicular to the lateral movement direction of the transfer frame on the transfer track. The rotating shafts of adjacent conveying rollers are connected by belt drive.

[0014] Preferably, the novel separation lifting and moving device further includes a drag chain assembly and a switch assembly. One end of the drag chain assembly is connected to a ground base next to the moving track, and the other end is connected to the moving frame. The switch assembly includes a limit switch and a photoelectric sensor disposed at preset positions on the moving frame and the moving track.

[0015] Preferably, the novel separating lifting and transferring device further includes a controller, which is electrically connected to both the lateral driving device and the driving assembly; the controller is configured to perform the following steps upon receiving a reset command: Drive the transfer frame to move horizontally back along the transfer track, and simultaneously control the drive component to make the lifting platform component move vertically downward, so that the lifting platform component moves along a downward composite trajectory to the low-position docking point at the origin of the transfer track; The drive assembly is driven to raise the lifting platform assembly vertically from the low-position stop point to the preset high-position working point.

[0016] Compared with the prior art, the present invention provides a novel separating lifting and transferring device, which has at least the following beneficial effects: Improved space utilization: Through integrated design, the originally separate lifting and transfer / return workstations are merged into a single workstation operation mode. This dual-workstation-in-one architecture significantly reduces the physical footprint of the equipment on the chassis assembly line in the vehicle plant, making a compact production line layout possible.

[0017] Improved production cycle time: Because lifting, lateral movement, roller conveying, and precise alignment are all achieved synchronously or continuously on a single machine, redundant station switching strokes and conveying waiting times are eliminated in traditional step-by-step operation modes. Combined with the oblique compound motion reset in the control logic, the work cycle is shortened, significantly improving production efficiency.

[0018] Improved operational stability: In response to the high center of gravity and off-center loading characteristics of the chassis assembly, lateral anti-sway components ensure smooth operation of the equipment throughout the entire process of heavy-load lifting and high-speed lateral movement.

[0019] Ensuring dynamic positioning accuracy: The rail alignment mechanism eliminates the mechanical cumulative tolerances caused by long-term operation of the equipment, and realizes rigid physical locking and precise docking of the high-level working point, ensuring the reliability of pallet conveying.

[0020] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0024] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0025] Example 1: As Figures 1-6 As shown, the present invention provides a novel separating lifting and transferring device, comprising: Transfer track 1 is set on the ground; The transfer frame 2 is slidably mounted on the transfer track 1, and its bottom is provided with a lateral drive device for driving it to move laterally along the transfer track 1; The lifting platform assembly 4 is vertically and flexibly mounted above the moving frame 2; Conveying assembly 5, installed on top of the lifting platform assembly 4, is used to carry and convey materials; Anti-sway component 3 is connected between the moving frame 2 and the lifting platform assembly 4. The anti-sway component 3 includes a vertically arranged guide member for constraining the horizontal degree of freedom of the lifting platform assembly 4 relative to the moving frame 2. The track alignment component 8 is located on one side of the transfer frame 2 and is used to lock the conveying component 5 to a preset separation station.

[0026] The working principle and beneficial effects of the above technical solution are as follows: This embodiment provides a novel separation lifting and transfer device. In the initial state, the lifting platform assembly 4 is at a preset high working point, and the rail alignment assembly 8 is in a pre-open state. The conveying assembly 5 starts, and the pallet carrying the assembled vehicle chassis is conveyed horizontally into the separation station. After the material has completely stopped on the conveying assembly 5, the external hoisting equipment separates the vehicle body from the connecting pipe. Subsequently, the rail alignment assembly 8 switches to the closed state. The lifting platform assembly 4, carrying the conveying assembly 5 and the empty pallet, performs a vertical descent. Throughout the entire descent stroke of the lifting platform assembly 4, the vertically arranged guide member in the anti-sway assembly 3 remains in contact with the side of the lifting platform assembly 4. The translational degrees of freedom of the lifting platform assembly 4 in the X and Y axes and the rotational degrees of freedom around the Z axis are restricted, retaining only the unidirectional vertical translational degree of freedom along the Z axis.

[0027] Once the lifting platform assembly 4 descends to the set low position height, the lateral drive device is activated, driving the transfer frame 2 to move laterally along the transfer track 1 towards the return side. During the acceleration and deceleration phases of the lateral movement, the anti-sway component 3 continuously provides anti-sway protection for the lifting platform assembly 4, limiting its swaying caused by inertial forces. After the lateral movement reaches the return side and stops, the lifting platform assembly 4 performs an upward movement, conveying the empty pallet horizontally out of the current workstation.

[0028] After the empty pallet is discharged, the equipment resets. The vertical descent of the lifting platform assembly 4 and the horizontal traverse return of the transfer frame 2 operate simultaneously. When the transfer frame 2 resets to the origin, the alignment assembly 8 reopens, and the lifting platform assembly 4 rises to the preset high working point and aligns with the rail. In this state, the conveying assembly 5 restarts, thus completing the reset and entering the next material receiving cycle.

[0029] The Z-axis represents the vertical lifting direction, corresponding to the lifting trajectory of the lifting platform assembly 4. The X-axis represents the horizontal lateral movement direction, corresponding to the trajectory of the transfer frame 2 moving back and forth on the ground transfer track 1. The Y-axis represents the horizontal conveying direction, that is, the forward and backward direction perpendicular to the track, corresponding to the direction in which the conveying assembly 5 at the top of the lifting platform sends the car chassis or pallet into and out of the workstation.

[0030] As an optional implementation, the traverse drive device includes a traverse geared motor and traveling wheels symmetrically mounted at the bottom of the traverse frame 2; the output shaft of the traverse geared motor is connected to the drive shaft of the traveling wheels. The upper surface of the traverse track 1 is machined with guide treads adapted to the traveling wheels to guide the traverse frame 2 to move with low friction.

[0031] The technical solution provided in this embodiment solves the technical problem of traditional automatic chassis separation processes where the lifting mechanism and the horizontal traverse trolley are set up as two independent workstations, resulting in a large occupation of physical space on the workshop floor. By structurally integrating the transfer track 1, transfer frame 2, lifting platform assembly 4, and anti-sway assembly 3, the original dual-workstation serial logistics process is merged into a single-workstation composite process, directly reducing the conveying stroke during workstation switching and eliminating the downtime of material transfer between different devices. The anti-sway assembly 3 solves the problem of center of gravity instability under multi-axis motion superposition conditions, providing dynamic attitude constraints throughout the motion and eliminating the interference of lateral inertia on the lifting trajectory. At the same time, when the equipment returns to the origin at high speed, the track alignment assembly 8 eliminates the accumulated mechanical stopping tolerance caused by the long-term operation of the traverse drive device, enabling the equipment to significantly increase the reset speed while still ensuring the accuracy of the material transfer coordinates at the highest working point, ensuring the efficient and stable operation of the entire production line.

[0032] Example 2: Based on Example 1 above, the novel separation lifting and moving device further includes a drive component; the drive component is inclinedly disposed between the moving frame 2 and the lifting platform component 4, and is used to drive the lifting platform component 4 to perform lifting and lowering actions relative to the moving frame 2.

[0033] A scissor support mechanism is also connected between the bottom of the lifting platform assembly 4 and the moving frame 2; the output end of the drive assembly acts on the bottom of the lifting platform assembly 4 or the cross axis of the scissor support mechanism; the drive assembly is a hydraulic cylinder (as a specific alternative to the drive assembly, it can also be configured as a pneumatic cylinder or an electric push rod), the bottom end of the cylinder of the hydraulic cylinder is hinged to the base of the moving frame 2, and the top end of its piston rod extends obliquely upward and is hinged to the lifting platform assembly 4; A bellows cover is also provided between the lifting platform assembly 4 and the moving frame 2. The upper edge of the bellows cover is connected to the lifting platform assembly 4, and the lower edge is connected to the moving frame 2. The hydraulic cylinder and the scissor support mechanism are both enclosed in the inner cavity of the bellows cover.

[0034] The working principle and beneficial effects of the above technical solution are as follows: When the new type of separating lifting and transferring equipment performs vertical lifting operations, the external hydraulic pump station injects pressurized oil into the oil chamber of the hydraulic cylinder. The piston rod of the hydraulic cylinder extends along its inclined physical mounting axis. The oblique linear thrust output by the hydraulic cylinder is decomposed into a vertical lifting component perpendicular to the horizontal plane and a horizontal lateral thrust component parallel to the horizontal plane. The vertical lifting component acts directly on the bottom of the lifting platform assembly 4 and the scissor support mechanism, driving the lifting platform assembly 4 to move upward along the Z-axis. The scissor support mechanism performs an unfolding action under the constraint of the hinge point, guiding the lifting trajectory.

[0035] Throughout the lifting process, as the vertical height of the lifting platform assembly 4 changes, the pleated structure of the bellows cover undergoes synchronized mechanical stretching or compression. The boundaries of the bellows cover remain closed, and the volume of its internal cavity dynamically changes with the lifting height. This isolates and protects the internal drive components and the lifting platform assembly 4.

[0036] This embodiment solves the technical problem that the overall height of the equipment in the retracted state is too large due to the use of a vertically arranged linear drive device, making it unsuitable for low-level chassis assembly operations. The obliquely arranged drive components effectively compress the Z-axis geometry of the equipment at its lowest position. The cooperation between the scissor lift support mechanism and the oblique hydraulic cylinder ensures the load-bearing rigidity of the foundation while providing a large lifting stroke. Simultaneously, the bellows-shaped protective cover eliminates the technical hazards of suspended welding slag, metal debris, and industrial dust adhering to the transmission components in automotive assembly workshops, extending maintenance intervals and improving the equipment's environmental adaptability under complex operating conditions.

[0037] Example 3: Based on Example 1 above, the guide member includes two parallel and vertically connected I-beam columns 11 connected to one side of the moving frame 2; the side of the lifting platform assembly 4 is connected to two sets of symmetrically arranged support brackets 12, the end of each set of support brackets 12 extends to the corresponding I-beam column 11, and is equipped with a rolling guide member 13 that rolls against the side wall of the I-beam column 11.

[0038] The rolling guide 13 includes at least two pairs of rollers. Vertical guide grooves are formed on opposite sides of the two I-beam columns 11. The two pairs of rollers are respectively rolled in the vertical guide grooves of the two I-beam columns 11. The rollers are used to limit the horizontal lateral movement of the lifting platform assembly 4 during lifting.

[0039] The working principle and beneficial effects of the above technical solution are as follows: During lifting and lateral movement, the two sets of support brackets 12 fixed to the sides of the lifting platform assembly 4 tend to displace along the X and Y axes. Two pairs of rollers mounted at the ends of the support brackets 12 abut tightly against the opposite sides of the two I-beam columns 11. The web of the I-beam column 11 provides Y-axis support, supporting the rollers on both sides. The wing plate structure of the I-beam column 11 provides support for the rolling surface of the rollers. This support force reacts to the lifting platform assembly 4 through the support brackets 12, forming a spatial constraint structure that restricts the lateral movement of the lifting platform assembly 4 along the X and Y axes. When the lifting platform assembly 4 moves along the Z-axis, the rollers roll along the wing plate surface of the I-beam column 11, reducing friction and avoiding sliding interference.

[0040] As an optional embodiment, to cope with the dynamic impact of the heavy-duty chassis under high-speed lateral and lifting combined motions, the rolling guide 13 is mounted on the support bracket 12 via a floating preload module. This floating preload module includes a set of disc springs or polymer damping elastic pads, allowing the rolling guide 13 to have a small amount of elastic floating space in the direction perpendicular to the surface of the I-beam column 11. During the acceleration / deceleration phase of the lifting platform assembly 4 moving along a downward-sloping combined trajectory or performing high-speed lateral movement, this floating preload module can dynamically absorb the instantaneous lateral sway energy generated by heavy-load inertia, converting the hard impact into a damping energy absorption process. This adaptive contact design ensures that the rollers maintain a constant preload force against the flange surface of the I-beam column 11 under any load condition, eliminating structural vibration caused by mechanical assembly gaps, thereby maintaining the horizontal degree of freedom constraint accuracy of the lifting platform assembly 4 relative to the transfer frame 2 throughout the entire stroke.

[0041] Example 4: Based on Example 1 above, the track alignment assembly 8 includes: A fixing frame 81 is installed on the ground on one side of the transfer track 1, and its top is provided with a support structure; The movable frame 82 is installed on the rear end face of the lifting platform assembly 4 and moves up, down and sideways synchronously with the lifting platform assembly 4. When the moving frame 2 is reset and the lifting platform assembly 4 rises to the preset high working point, the movable frame 82 is mechanically locked and connected to the fixed frame 81 through the docking structure.

[0042] The docking structure includes: A limiting plate 811 is symmetrically arranged on the top of the fixing frame 81 and has a locking groove 812, with an opening on one side of the locking groove 812; The movable docking assembly includes a drive motor 822, a rotating plate 823, a connecting rod 824, a swing arm 825, and a locking bearing wheel 821. The drive motor 822 is mounted at the center of the movable frame 82, and the rotating plate 823 is connected to its output shaft. A connecting rod 824 is hinged to each end of the rotating plate 823. The swing arm 825 is hinged to both sides of the movable frame 82, and the locking bearing wheel 821 is connected to the swing arm 825. The other end of the connecting rod 824 is hinged to the swing arm 825. When the lifting platform assembly 4 rises to its position, the locking bearing wheel 821 locks into the locking groove 812 to perform docking.

[0043] The working principle and beneficial effects of the above technical solution are as follows: When the transfer frame 2, carrying the lifting platform assembly 4, returns to its starting point and the lifting platform assembly 4 rises vertically to the preset high working point, the rail alignment assembly 8 enters the pre-dock state. At this time, the movable frame 82 and the fixed frame 81 are roughly aligned in spatial coordinates. Subsequently, the drive motor 822 starts, and the motor output shaft drives the rotating plate 823 located at the center of the movable frame 82 to rotate in a circle. Since the two ends of the rotating plate 823 are symmetrically hinged with connecting rods 824, the swing arms 825 on both sides are pushed to perform synchronous outward swinging motion around their hinge points on the movable frame 82. The locking bearing wheel 821 at the end of the swing arm 825 accurately enters the locking groove 812 of the limiting plate 811 from the opening side, realizing the locking of the movable frame and the fixed frame. After the material transfer process is completed, the drive motor 822 rotates in the opposite direction, and drives the locking bearing wheel 821 out of the locking groove 812 through the linkage mechanism, releasing the lock and preparing for the subsequent descent and transfer cycle.

[0044] The alignment assembly provided in this embodiment addresses the mechanical cumulative tolerance problem caused by the excessively long operation and frequent start-stop cycles of the transfer track 1 in the chassis assembly line. It adopts an active linkage locking mechanism instead of the traditional passive mortise lock or funnel-type alignment. Through the combination of the rotating plate 823 and the double connecting rod 824, the swing stroke of the swing arm 825 forms a fault-tolerant guide zone. With the rolling intervention of the locking bearing wheel 821, it can actively correct and eliminate the slight deviation of the transfer frame 2 in the horizontal lateral direction (X-axis), thereby improving the positioning accuracy of the equipment.

[0045] The drive motor 822 is centrally located and distributes power to both sides simultaneously via the rotating plate 823. This ensures that the two sets of locking bearing wheels 821 can engage with the limit plate 811 at a synchronized frequency and with equal locking force, thus offsetting the lateral torque generated by unilateral locking and preventing localized stress concentration or tilting of the lifting platform assembly 4 during rail alignment. The rolling contact between the locking bearing wheel 821 and the locking groove 812 ensures low wear and low noise during engagement while maintaining locking rigidity.

[0046] As an optional embodiment, the linkage mechanism in this embodiment is configured as an over-dead-point self-locking structure. When the locking bearing wheel 821 is fully inserted into the locking groove 812 and abuts against the bottom of the groove, the hinge point between the rotating plate 823 and the connecting rod 824 rotates to a position exceeding the physical dead point of the line connecting the rotation center point of the rotating plate 823 and the hinge point at the end of the connecting rod. In this state, the locking bearing wheel 821 and the locking groove 812 form a rigid physical lock. Because the mechanism is in the over-dead-point locked state, any thrust from the side (X-axis direction) of the conveying component 5 or the reverse force generated by equipment vibration cannot drive the rotating plate 823 to rotate in the opposite direction through the connecting rod 824. Even if the drive motor 822 loses power, the mechanism can still maintain the self-locking state, ensuring the absolute stillness and safety of the coordinates during material transfer at the high-level working point. In addition, the locking groove 812 opening of the limiting plate 811 is provided with a wedge-shaped misalignment guide surface, which, together with the rolling intervention of the locking bearing wheel 821, can actively correct and forcibly eliminate the slight stopping deviation of the transfer frame 2 in the horizontal lateral direction.

[0047] Example 5: Based on Example 1 above, the conveying assembly 5 is configured as a motorized roller bed assembly, including multiple parallel conveying rollers and a roller bed drive motor that drives the conveying rollers 51 to rotate. The conveying direction of the conveying rollers 51 is perpendicular to the lateral movement direction of the transfer frame 2 on the transfer track 1. The rotating shafts of adjacent conveying rollers 51 are connected by belt drive.

[0048] The working principle and beneficial effects of the above technical solution are as follows: During the material receiving or discharging stage, the control system switches on the power to the roller bed drive motor. The roller bed drive motor drives the first conveyor roller 51, which serves as the drive shaft, to rotate. The pulley on the shaft of the conveyor roller 51 drives all the conveyor rollers 51 to rotate synchronously. The pallet carrying the chassis workpiece contacts the cylindrical surface of the conveyor roller 51 and is driven by the tangential friction force of the surface to move smoothly along a straight trajectory perpendicular to the lateral direction. This ensures the speed stability and system durability of the material during the transfer process in the perpendicular lateral direction.

[0049] Example 6: Based on Example 1 above, the novel separation lifting and moving device further includes a drag chain assembly 6 and a switch assembly 7. One end of the drag chain assembly 6 is connected to the ground base next to the moving track 1, and the other end is connected to the moving frame 2. The switch assembly 7 includes a limit switch (or micro switch) and a photoelectric sensor (or electromagnetic proximity switch, ultrasonic displacement sensor) disposed at a preset position on the moving frame 2 and the moving track 1.

[0050] The working principle and beneficial effects of the above technical solution are as follows: When the lateral drive device drives the transfer frame 2 to perform frequent horizontal lateral movements along the transfer track 1, the drag chain assembly 6 constrains the scattered cables within a protected fixed bending radius, eliminating the potential for cables to interfere with the track or surrounding materials, and ensuring the physical safety of power supply and signal transmission.

[0051] When the transfer frame 2 moves to its physical limit near the end of the transfer track 1, a mechanical stop installed at the bottom of the frame contacts the actuation lever of the limit switch. Upon triggering, the lateral drive device is shut down, stopping the lateral movement. Simultaneously, as the lifting platform assembly 4 moves along the Z-axis, a photoelectric sensor emits an infrared detection beam. When the blocking plate on the side of the lifting platform assembly 4 passes a set height and cuts off the beam, the lifting is complete, and the lifting stops upon triggering. This setup enables real-time detection of position and movement status, ensuring the accuracy of the automated production line operation and the convenience of troubleshooting.

[0052] Example 7: Based on Example 1 above, the novel separating lifting and transferring device further includes a controller, which is electrically connected to the lateral driving device and the driving assembly respectively; the controller is configured to perform the following steps upon receiving a reset command: Drive the transfer frame 2 to move horizontally back along the transfer track 1, and simultaneously control the drive component to make the lifting platform assembly 4 move vertically downward, so that the lifting platform assembly 4 moves along a downward composite trajectory to the low-position docking point at the origin of the transfer track 1. In response to the moving frame 2 reaching the origin, the driving component is driven to make the lifting platform assembly 4 rise vertically from the low-position docking point to the preset high-position working point, so that the movable frame 82 and the fixed frame 81 perform locking docking.

[0053] The working principle and beneficial effects of the above technical solution are as follows: The controller is configured to execute the following specific condition determination and segmented interlock control logic upon receiving a reset command: First reset phase (dual-axis compound motion phase): In response to the reset command, the controller synchronously outputs a preset return frequency signal to the lateral drive device (lateral reduction motor) and a descent control signal to the drive assembly (reversing valve of the hydraulic cylinder). At this time, the traveling frame 2 starts to move laterally back along the traveling track 1, while the lifting platform assembly 4 descends vertically relative to the traveling frame 2. To ensure the safety of the compound trajectory, the controller performs the following position monitoring: During the movement, the controller reads the status of the photoelectric sensor (or ultrasonic displacement sensor) and the limit switch in the switch assembly 7 in real time.

[0054] If the lifting platform assembly 4 reaches the vertical minimum limit point before the moving frame 2: the shielding plate installed on the side of the lifting platform assembly 4 cuts off the photoelectric sensor beam at the set height, the controller receives the signal that it has descended to the position, and immediately cuts off the power output of the drive assembly (e.g., controls the hydraulic system to unload or closes the proportional valve), so that the lifting platform assembly 4 remains stationary in the vertical direction, while the lateral drive device continues to drive the moving frame 2 to move laterally until it touches the origin. If the moving frame 2 reaches the horizontal origin before the lifting platform assembly 4: the mechanical stop at the bottom of the moving frame 2 first touches the limit switch set at the origin of the moving track 1. The controller receives the horizontal positioning signal and immediately controls the lateral drive device to perform braking and locking, while the drive assembly continues to drive the lifting platform assembly 4 to descend vertically until the photoelectric sensor beam is cut off.

[0055] Through the above-mentioned asynchronous interlocking logic of first-come-first-served and dual-axis closed loop, the system can safely guide the conveying component 5 to move along a composite trajectory that is diagonally downward in the absolute space coordinate system to the low-position docking point at the origin of the transfer track 1, regardless of how the response speed or load of the two heterogeneous power systems changes, and eliminates the potential mechanical jamming caused by the mismatch of the two axes speeds.

[0056] Second reset stage (vertical precision alignment stage): In response to the travel frame 2 touching the origin limit switch and the lifting platform assembly 4 cutting off the lowest position photoelectric sensor beam (i.e. both axes confirm reaching the origin low position docking point), the controller keeps the lateral drive device in a motor braking or mechanical brake locking state, eliminating the horizontal degree of freedom.

[0057] Subsequently, the controller outputs a lifting signal to the drive assembly, driving the hydraulic cylinder to extend obliquely upwards, causing the lifting platform assembly 4 to perform a purely vertical upward movement from the low-position docking point. During the upward movement, the movable frame 82 installed on the rear end of the lifting platform assembly 4 rises vertically until it reaches the preset high-position working point, triggering the high-position limit switch. At this time, the movable frame 82 and the fixed frame 81 achieve rigid interlocking alignment in the vertical direction. Then, the controller starts the drive motor 822 of the rail alignment assembly 8 to perform active linkage locking docking, completing the reset.

[0058] This embodiment resolves the conflict between dynamic stability and docking reliability during high-speed repositioning of heavy-duty mobile equipment through a two-stage path design of compound descent and vertical ascent. The first stage, a downward compound motion, utilizes the auxiliary effect of gravity to reduce the burden on the hydraulic system and maintains a low center of gravity throughout the high-speed lateral movement, effectively suppressing structural vibration and instability caused by uneven tracks or starting inertia. The second stage, a vertical ascent design, ensures accurate connection of the rail assembly 8. This achieves a fusion of smooth operation and precise docking, improving the safety of the chassis assembly line.
