Description

Technical Field

[0001] This invention relates to the field of automobile dismantling technology, and in particular to a scrapped automobile dismantling line and its usage method. Background Technology

[0002] After a certain period of use, automobiles experience significant wear and tear on their parts, resulting in increased exhaust emissions and decreased safety. From both a safety and environmental perspective, vehicles that have reached their service life and corresponding wear levels must be scrapped. Failure to properly recycle and reuse the parts and materials of scrapped vehicles leads to a substantial waste of resources and severe environmental pollution. Instead of discarding the entire vehicle, scrapped vehicles should be disposed of by recycling intact or reworkable parts to achieve resource reuse. Vehicle dismantling is the process of separating the entire vehicle, its assemblies, and its components.

[0003] In dismantling assembly line operations, the prepared vehicle body usually needs to be moved to a designated workstation first. Current technology commonly uses overhead cranes with wire ropes or hooks for lifting. However, these conventional lifting methods have significant drawbacks: First, during lifting and movement, the vehicle body is prone to swaying, rotating, or even slipping, resulting in poor positioning and fixation, posing a significant safety hazard. Second, before dismantling and transporting the vehicle, there may be disassembled or loose parts (such as screws, small trim panels, etc.) remaining in the chassis, doors, etc. During the bumpy lifting process, these parts are easily detached and scattered on the ground or equipment. This not only causes parts loss, affecting subsequent sorting and recycling, but also risks safety accidents or hinders operations at other workstations. Summary of the Invention

[0004] The purpose of this invention is to address the problems in existing technologies where car hoisting relies on manual steel wire rope binding and hook unbinding, resulting in low operational efficiency, high labor costs, and the risk of vehicle swaying and slipping during hoisting, posing significant safety hazards. Furthermore, it addresses the issue of scattered parts being easily lost during transport, leading to low utilization of recyclable resources and potential safety accidents caused by scattered parts. The invention proposes a scrap car dismantling line and its usage method. Through overall modular optimization of vehicle clamping, parts anti-scattering, and hoisting sequence control, an automated dismantling line hoisting device with pure mechanical linkage as its core has been developed. The solution organically combines four sets of three-dimensional gripping and support positioning mechanisms triggered by the vehicle's own weight, a material receiving component with automatic lifting and retraction linkage, and a hydraulic interlocking full-process time-series collaborative control system. This achieves fully automated operation of scrap cars from grabbing, supporting, clamping, locking, transporting, and lowering through mechanical linkage and hydraulic control.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A scrapped car dismantling line includes a track frame and a moving block that moves along the track frame, and further includes: Mounting plate, which is fixedly connected to the movable block, and a first hydraulic cylinder is fixedly mounted on the mounting plate; A hanger, which is fixed to the bottom of the telescopic end of the first hydraulic cylinder, and a clamping frame is provided on the hanger; The support and positioning mechanism consists of four sets, which are respectively located at the four corners of the gripper frame to support and position the vehicle body to be disassembled. And receiving components, which are provided in two sets and symmetrically arranged on both sides of the clamping frame, for receiving parts that fall off during the transfer of the vehicle body to be disassembled; The support and positioning mechanism includes a support component for supporting the vehicle body to be disassembled and a positioning component disposed on the support component and limiting the displacement of the vehicle body to be disassembled.

[0006] Preferably, the hanger includes a hanging plate fixedly connected to the telescopic end of the first hydraulic cylinder, a plurality of frames disposed on the hanging plate, a base plate disposed at both ends of the bottom of the frames, and a first elastic telescopic rod disposed between the top of the base plate and the bottom of the clamping frame. The clamping frame includes two U-shaped frames fixedly connected to the top of the first elastic telescopic rod and a frame plate disposed between the two U-shaped frames.

[0007] Preferably, the support assembly includes a side plate fixed to the bottom of the frame plate, a second hydraulic cylinder fixedly connected to the side plate, and an L-shaped support seat connected to the telescopic end of the second hydraulic cylinder.

[0008] Preferably, the positioning assembly includes a slider slidably disposed on an L-shaped support, a force-bearing seat disposed on the top of the slider, a first elastic element disposed between the L-shaped support and the force-bearing seat, a movable plate disposed at the bottom of the slider, a support plate fixed on the L-shaped support, a swing rod rotatably connected to the support plate via a first pin, and a connecting rod hinged between the movable plate and the swing rod.

[0009] Preferably, the end of the swing rod away from the connecting rod is rotatably connected to a Y-shaped plate via a second pin, and both ends of the Y-shaped plate are provided with abutment rods.

[0010] Preferably, the L-shaped support includes a push plate fixedly connected to the telescopic end of the second hydraulic cylinder, a second elastic telescopic rod fixedly connected to the push plate, and an L-shaped seat body connected to the movable end of the second elastic telescopic rod, wherein the push plate is slidably connected to the L-shaped seat body. A third elastic telescopic rod is fixedly provided on the push plate, and an insertion block that slides in the L-shaped seat is fixedly provided at the end of the third elastic telescopic rod away from the push plate. Several slots that cooperate with the insertion block are provided on the slider.

[0011] Preferably, the receiving assembly includes an upper slide groove and a lower slide groove formed on the U-shaped frame, an upper slide plate fixedly connected in the upper slide groove, a lower slide plate slidably connected in the lower slide groove, a second elastic element disposed between the lower slide plate and the inner wall of the lower slide groove, a flexible folding metal plate disposed between the upper slide plate and the lower slide plate, and a steel wire rope disposed in the lower slide plate, wherein the end of the steel wire rope away from the lower slide plate passes through the frame plate and is connected to the mounting plate.

[0012] Preferably, the slide plate includes a slide seat slidably connected in the slide groove and a plate body slidably connected to the slide seat via a fourth elastic telescopic rod. The plate body is fixedly connected to a flexible folding metal plate. A first force-bearing inclined surface is provided on the side of the plate body away from the flexible folding metal plate. The flexible folding metal plate is configured as a V-shaped folding plate with a lower middle and higher sides.

[0013] Preferably, the bottom of the sliding plate is connected to an elastic telescopic rod with an internal spring. The bottom plates on both sides of the middle of the U-shaped frame are provided with insertion holes that cooperate with the elastic telescopic rod. A second force-bearing inclined surface is provided on one side of the telescopic end of the elastic telescopic rod. The end of the steel wire rope away from the mounting plate passes through the frame plate, the sliding plate, and the elastic telescopic rod in sequence and is finally fixedly connected to the telescopic end of the elastic telescopic rod.

[0014] This invention also discloses a method for using a scrapped car dismantling line, comprising the following steps: S1: The moving block slides along the track frame, moving the entire hoisting device directly above the car body to be dismantled; S2: Control the extension of the first hydraulic cylinder to drive the overall descent of the hanger and clamping frame. During this process, the wire rope remains stationary relative to the clamping frame, while the lower slide plate moves down with the clamping frame, causing the wire rope to exert tension on the lower slide plate, which in turn moves up in the sliding groove and compresses the second elastic element. Before this, the wire rope must first pull the telescopic end of the elastic telescopic rod to disengage it from the insertion hole in the bottom plate before it can pull the lower slide plate, causing the flexible folding metal plate and the lower slide plate to retract and fold towards the side of the clamping frame. Before contacting the top of the vehicle body to be disassembled, the flexible folding metal plate has retracted to the side of the vehicle body to be disassembled to avoid collision and damage with the vehicle body below. As the clamping frame continues to move down, the flexible folding metal plate continues to be folded and moves towards the side of the clamping frame. S3: The clamping frame is lowered to a suitable height so that the support and positioning mechanisms at its four corners are located around the vehicle body to be disassembled. Then, the four second hydraulic cylinders are extended. The telescopic ends of the second hydraulic cylinders push the push plate. The push plate transmits the force to the L-shaped seat through the second elastic telescopic rod, driving the four L-shaped seats to move in the front, rear, left and right directions of the vehicle body to be disassembled, until the horizontal part of each L-shaped seat extends under the car chassis. S4: Then, control the first hydraulic cylinder to retract, driving the lifting frame and clamping frame to rise as a whole. Due to the weight of the vehicle body to be disassembled, the first elastic telescopic rod is compressed, which plays a buffering role. As it is lifted, the bottom of the vehicle body to be disassembled contacts the four force seats. The force seats are pressed and drive the slider to slide down on the L-shaped seat. As the slider moves down, it drives the swing rod to rotate around the first pin on the support plate through the connecting rod. The free end of the swing rod swings until the two abutting rods press tightly against the side of the vehicle body to be disassembled, thereby effectively limiting the vehicle body from both sides and preventing it from shaking during lifting. At this time, the second hydraulic cylinder continues to apply a pushing force to the push plate. During the movement, when the L-shaped seat comes into contact with the body of the vehicle to be disassembled, the third elastic telescopic rod is compressed, and the push plate continues to retract relative to the L-shaped seat. The push plate drives the insert block to move, so that it is inserted into the corresponding slot on the slider, thus restricting the clamping state of the vehicle to be disassembled at this time. S5: During the lifting process, as the clamping frame rises, the distance between the clamping frame and the mounting plate shortens, and the wire rope loosens. At this time, the compressed second elastic element recovers, pushing the lower slide plate to reset in the sliding groove, thereby driving the flexible folding metal plate to unfold outward to the horizontal working position. When the lower slide plate is reset in place, the elastic telescopic rod at its bottom extends under the action of the internal spring. Its telescopic end aligns with the insertion hole and automatically springs in and locks, preventing the lower slide plate from sliding during transportation. The unfolded V-shaped flexible folding metal plate is located under the vehicle body to be disassembled, and can catch the scattered parts that fall from the vehicle body to be disassembled during transportation bumps. S6: Then control the displacement of the moving block, and smoothly transfer the clamped and fixed car to the target dismantling station along the track frame. After reaching the target station, control the first hydraulic cylinder to slowly extend and place the car smoothly. Then control the second hydraulic cylinder to retract and drive the L-shaped seat to exit from under the car chassis, and release the support and lateral limit. Finally, the gantry and clamps are raised, ready for the next work cycle.

[0015] Compared with the prior art, the present invention provides a scrapped car dismantling line and its usage method, which has the following beneficial effects: 1. In this invention, through the coordinated work of four sets of support and positioning mechanisms, the vehicle body is lifted from the bottom and combined with side adaptive clamping, achieving a stable three-dimensional hold on the vehicle body. The L-shaped support base provides multi-point support from below the chassis. During the lifting process, the vehicle body's own weight automatically triggers the side clamping mechanism, forming a reliable limit on the vehicle body from both sides. This integrated support and limit design, which is linked with the lifting action, overcomes the risks of vehicle body swaying, rotating, or even slipping during traditional wire rope hoisting, improving the safety of the hoisting process. At the same time, the process is highly automated, reducing the time spent on manual binding, hooking, and adjustment, making the process of grabbing, fixing, transferring, and releasing the vehicle body more coherent and efficient, suitable for the rhythm of disassembly assembly lines.

[0016] 2. In this invention, by setting automatically retractable receiving components on both sides of the clamping frame, the flexible folding metal plate can automatically retract to avoid the vehicle body when the lifting device descends and approaches it; when the vehicle body is lifted and transported, it can automatically unfold and reset, forming a V-shaped receiving groove located under the vehicle body, which can effectively catch scattered parts such as screws, clips, and small decorative panels that fall from the chassis and gaps of the vehicle body during transport. This solves the problem of parts being scattered and lost in traditional lifting methods, improves the recycling rate of recyclable parts, and meets the requirements of resource recycling; at the same time, it avoids pollution and safety hazards to the ground, other equipment, and workstations caused by scattered parts, maintains the cleanliness and order of the dismantling operation area, and improves the safety and standardization of the overall working environment.

[0017] 3. In this invention, the second and third elastic telescopic rods in the support and positioning mechanism provide buffering and stroke compensation, enabling the L-shaped support seat to adapt to slight differences in chassis height and body contours of different vehicle models. The material receiving assembly, through the linkage of the wire rope, elastic telescopic rod, and second elastic element, automatically avoids the vehicle body during descent, preventing damage to flexible folding metal plates and other components from rigid collisions. The cooperation between the elastic telescopic rod and the insertion hole ensures the secure locking of the material receiving assembly during transfer. This allows the equipment to adapt to more vehicle models, reduces equipment damage caused by misoperation or interference, extends the service life of key components, and reduces maintenance costs.

[0018] 4. In this invention, the entire system achieves timing control and automated operation of complex actions through hydraulic drive and mechanical linkage. During descent, the timing of the wire rope traction ensures that the receiving component unlocks first and then retracts to avoid obstruction. During support, the cooperation between the insert and the slot achieves pre-locking of the slider. During lifting, the vehicle's own weight sequentially triggers the unlocking of the insert, the downward movement of the slider, and the action of the lateral clamping mechanism, while the receiving component automatically unfolds and locks. The coordinated action of each functional module ensures stable and reliable operation. The entire operation process requires almost no manual intervention, has a high degree of automation, and is reliable in operation. It effectively reduces the labor intensity and skill requirements of operators and improves the overall intelligence level of dismantling operations. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] like Figures 1 to 3 As shown, this embodiment proposes a scrapped car dismantling line, including a track frame 1 and a moving block 101 that moves along the track frame 1. It also includes: a mounting plate 2, a hanger 3, a support and positioning mechanism, and a receiving assembly. The mounting plate 2 is fixedly connected to the moving block 101, and a first hydraulic cylinder 201 is fixedly mounted on the mounting plate 2. The hanger 3 is fixedly mounted at the bottom of the telescopic end of the first hydraulic cylinder 201, and a clamping frame 4 is mounted on the hanger 3. Four sets of support and positioning mechanisms are provided, respectively located at the four corners of the clamping frame 4, for supporting and positioning the car body to be dismantled. Two sets of receiving assemblies are provided, symmetrically arranged on both sides of the clamping frame 4. Used to pick up parts that fall off during the transfer of a vehicle body to be disassembled; the support and positioning mechanism includes a support component for supporting the vehicle body to be disassembled and a positioning component set on the support component to limit the displacement of the vehicle body to be disassembled; the equipment can be linked with the PLC system of the disassembly production line through the controller to realize the fully automated cycle matching of the vehicle body loading, hoisting and transportation, and disassembly station placement; an industrial vision camera can be added to the clamping frame 4 and electrically connected to the controller, which can automatically identify the vehicle model and chassis outline, automatically plan the support position and cylinder stroke of the four sets of support and positioning mechanisms, and realize unmanned adaptive clamping and hoisting of different vehicle models; Specifically, the moving block 101 runs on the track frame 1, moving the entire hoisting device directly above the scrapped vehicle. The first hydraulic cylinder 201 is activated, driving the lifting frame 3 and gripping frame 4 to descend as a whole, allowing the gripping frame 4 to cover the vehicle body to be dismantled from above. Then, the four sets of support and positioning mechanisms are controlled to operate. First, each support component extends and is positioned at the bottom of the vehicle body. Then, the first hydraulic cylinder 201 retracts, providing stable support from the bottom of the vehicle body. Subsequently, each positioning component operates, limiting the vehicle body from the side to prevent it from swaying, rotating, or slipping during subsequent hoisting. This allows the vehicle body, firmly gripped by the support and positioning mechanisms, to be lifted smoothly. This multi-point rigid or semi-rigid gripping method, compared to traditional flexible slings such as ropes, effectively prevents the vehicle body from swaying, rotating, or even slipping during hoisting, greatly reducing the risk of damage. This design mitigates the risk of falling objects from heights, ensures operational safety, and enables more precise positioning and placement. It reduces reliance on overhead cranes and manual hooks, shortens the time for transferring and fixing the vehicle body between workstations, and facilitates efficient, streamlined dismantling operations. At this point, the receiving components on both sides are in their working positions, located below the vehicle body, ready to catch falling objects, preventing the loss and mixing of parts, improving the recycling rate of recyclable materials, and preventing safety hazards caused by parts scattering on the ground and interference with other work areas. Then, the moving block 101 moves along the track to transfer the vehicle body to the designated dismantling workstation. Upon arrival at the workstation, the first hydraulic cylinder 201 extends, smoothly lowering the vehicle body. Next, the support and positioning mechanism releases the constraint on the vehicle body, and finally, the hanger 3 and the clamping frame 4 are lifted and reset, completing one work cycle.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in a preferred embodiment, based on the above method, the hanger 3 further includes a hanging plate 301 fixedly connected to the telescopic end of the first hydraulic cylinder 201, several frames 302 disposed on the hanging plate 301, a base plate 303 disposed at both ends of the bottom of the frame 302, and a first elastic telescopic rod 304 disposed between the top of the base plate 303 and the bottom of the clamping frame 4; a rigid limiting sleeve is provided on the outer side of the first elastic telescopic rod 304 to limit the maximum compression stroke of the telescopic rod and avoid structural damage caused by excessive compression under heavy load; The clamping frame 4 includes two U-shaped frames 401 fixedly connected to the top of the first elastic telescopic rod 304 and a frame plate 402 disposed between the two U-shaped frames 401; Specifically, the lifting plate 301 is fixedly connected to the telescopic end of the first hydraulic cylinder 201, suspending the entire lifting frame 3 and the clamping frame 4 below the hydraulic cylinder. The clamping frame 4 is elastically connected to the base plate 303 of the lifting frame 3 through multiple first elastic telescopic rods 304. When the first hydraulic cylinder 201 drives the lifting frame 3 to lift as a whole, the lifting plate 301, frame 302 and base plate 303 move accordingly. Since the clamping frame 4 is connected to the lifting frame 3 through the first elastic telescopic rods 304, when the clamping frame 4 contacts or carries the vehicle body, the first elastic telescopic rods 304 can provide elastic extension and contraction to buffer the impact force during the lifting process. Especially when initially lifting the vehicle body, it can absorb part of the instantaneous load and achieve a smooth start. The rigid collision or hard pull between the hydraulic cylinder and the vehicle body not only protects the lifting equipment and vehicle structure from instantaneous overload damage, but also makes the start and stop of the entire lifting process smoother and improves the operation softness.

[0025] like Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 9 As shown, in a preferred embodiment, based on the above method, the support assembly further includes a side plate 5 fixed to the bottom of the frame plate 402, a second hydraulic cylinder 501 fixedly connected to the side plate 5, and an L-shaped support seat 502 connected to the telescopic end of the second hydraulic cylinder 501; the four sets of second hydraulic cylinders 501 are supplied with oil synchronously by the same hydraulic pump station, and a synchronous flow divider valve and a stroke sensor are set to ensure that the telescopic speed and stroke of the four cylinders are completely consistent, and to ensure that the four sets of L-shaped seats 5023 extend and retract synchronously, so that the vehicle body is supported stably and the risk of tilting and slipping is avoided; Furthermore, the positioning assembly includes a slider 6 slidably disposed on the L-shaped support 502, a force-bearing seat 601 disposed on the top of the slider 6, a first elastic element 602 disposed between the L-shaped support 502 and the force-bearing seat 601, a movable plate 603 disposed at the bottom of the slider 6, a support plate 604 fixedly disposed on the L-shaped support 502, a swing rod 605 rotatably connected to the support plate 604 via a first pin, and a connecting rod 606 hinged between the movable plate 603 and the swing rod 605; rollers may be provided on the force-bearing seat 601 so that the L-shaped support 502 drives the force-bearing seat 601 to move relative to the vehicle body; Furthermore, the end of the swing rod 605 away from the connecting rod 606 is rotatably connected to a Y-shaped plate 7 via a second pin, and both ends of the Y-shaped plate 7 are provided with abutment rods 701; Furthermore, the L-shaped support 502 includes a push plate 5021 fixedly connected to the telescopic end of the second hydraulic cylinder 501, a second elastic telescopic rod 5022 fixedly connected to the push plate 5021, and an L-shaped seat body 5023 connected to the movable end of the second elastic telescopic rod 5022. The push plate 5021 is slidably connected inside the L-shaped seat body 5023. A third elastic telescopic rod 8 is fixed on the push plate 5021. A plug 9 that slides in the L-shaped seat 5023 is fixed at one end of the third elastic telescopic rod 8 away from the push plate 5021. A number of slots 10 that cooperate with the plug 9 are opened on the slider 6. Multiple sets of plugs 9 and the third elastic telescopic rod 8 connected to them can be arranged in the vertical direction of the slots 10 to ensure that at least one plug 9 is connected to the slot 10. Specifically, when the horizontal height of the support assembly is slightly lower than the chassis of the vehicle to be disassembled, the second hydraulic cylinder 501 is extended, and its telescopic end pushes the L-shaped support seat 502 to move horizontally towards the vehicle body, so that the horizontal part of the L-shaped seat 5023 extends under the chassis. Subsequently, the first hydraulic cylinder 201 is retracted, and the force-bearing seat 601 moves upward with the L-shaped support seat 502, lifting the vehicle body. The weight of the vehicle body acts on the force-bearing seat 601, overcoming the elastic force of the first elastic element 602, forcing the slider 6 to slide downward along the L-shaped support seat 502. When slider 6 moves downward, it pushes swing rod 605 to rotate around the first pin shaft via connecting rod 606. The rotation of swing rod 605 causes the Y-shaped plate 7 and two abutment rods 701 at its end to swing towards the side of the vehicle body until the two abutment rods 701 are tightly pressed against the appropriate position on the side of the vehicle body, thereby reliably limiting the vehicle body from the side and preventing it from swaying during hoisting. The design of Y-shaped plate 7 allows the two abutment rods 701 to adapt to the side profile of the vehicle body, providing two contact points, increasing the contact area and stability with irregular vehicle body sides. This creates a more effective surface constraint, better preventing the vehicle body from rotating or swaying horizontally during hoisting. Subsequently, the second hydraulic cylinder 501 extends further, pushing the L-shaped seat 5023. While the cylinder continues to push after the L-shaped seat 5023 contacts the vehicle body, the push plate 5021 retracts relative to the L-shaped seat 5023, compressing the second elastic telescopic rod 5022 to provide cushioning. Simultaneously, the push plate 5021, through the third elastic telescopic rod 8, moves the insert block 9, causing it to insert into a slot on the slider 6. In section 10, the position of slider 6 is locked to maintain the stability of the clamped state during the lifting of the vehicle body; all hydraulic cylinders are equipped with hydraulic locks (two-way hydraulic control check valves), which can automatically lock the oil circuit when the cylinder stops moving. Even if the hydraulic line loses pressure or bursts, the cylinder can still maintain the current stroke to prevent the L-shaped seat 5023 from retracting and the vehicle body from falling; at the same time, the hydraulic system is equipped with an overload relief valve to avoid structural damage caused by overload, which complies with the mandatory safety specifications for lifting and hoisting equipment; the hydraulic system adopts explosion-proof hydraulic valve groups.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 10 and Figure 11As shown, in a preferred embodiment, based on the above method, the receiving assembly further includes an upper sliding groove 11 and a lower sliding groove 12 formed on the U-shaped frame 401, an upper sliding plate 111 fixedly connected in the upper sliding groove 11, a lower sliding plate 121 slidably connected in the lower sliding groove 12, a second elastic element 122 disposed between the lower sliding plate 121 and the inner wall of the lower sliding groove 12, a flexible folded metal plate 13 disposed between the upper sliding plate 111 and the lower sliding plate 121, and a steel wire rope 14 disposed in the lower sliding plate 121. The end of the steel wire rope 14 away from the lower sliding plate 121 passes through the frame plate 402 and is connected to the mounting plate 2. Wear-resistant guide strips are provided in the sliding groove to avoid jamming caused by dust and oil. On the wire path of the steel wire rope 14, all wire holes are provided with wear-resistant nylon guide sleeves to avoid direct friction between the steel wire rope 14 and the metal hole wall, extend the service life of the steel wire rope 14, and prevent breakage and failure. Furthermore, the sliding plate 121 includes a slide block 1211 slidably connected in the sliding groove 12 and a plate body 1213 slidably connected to the slide block 1211 via a fourth elastic telescopic rod 1212. The plate body 1213 is fixedly connected to the flexible folding metal plate 13. A first force-bearing inclined surface is provided on the side of the plate body 1213 away from the flexible folding metal plate 13. The flexible folding metal plate 13 is configured as a V-shaped folding plate with a lower middle and higher sides. The V-shaped structure effectively prevents the picked-up parts from falling off from both sides of the folding plate. Furthermore, the bottom of the sliding plate 121 is connected to an elastic telescopic rod 15 with an internal spring. The bottom plates 303 on both sides of the middle of the U-shaped frame 401 are provided with insertion holes 151 that cooperate with the elastic telescopic rod 15. A second force-bearing inclined surface is opened on one side of the telescopic end of the elastic telescopic rod 15. The end of the steel wire rope 14 away from the mounting plate 2 passes through the frame plate 402, the sliding plate 121, and the elastic telescopic rod 15 in sequence and is finally fixedly connected to the telescopic end of the elastic telescopic rod 15. Specifically, when the first hydraulic cylinder 201 drives the lifting frame 3 and the clamping frame 4 to descend as a whole, the position of the mounting plate 2 and the wire rope 14 fixed thereon remains unchanged, while the lower slide plate 121, the elastic telescopic rod 15, and the bottom end of the wire rope 14 move down with the clamping frame 4. Since the length of the wire rope 14 is fixed, its bottom end tends to pull downward. This pulling force first acts on the telescopic end of the elastic telescopic rod 15, overcoming the internal spring force and pulling the telescopic end out of the insertion hole 151 of the base plate 303, thus unlocking. The pulling force driving the wire rope 14 comes directly from the relative movement between the lifting frame 3 and the clamping frame 4, without the need for an additional independent power source. This reflects a high degree of functional integration and timing coordination, making the material receiving function an integral part of the entire lifting system. An organic, automatically operating component enhances the overall integrity and automation level of the equipment. Subsequently, the tension of the steel wire rope 14 directly acts on the lower slide plate 121, overcoming the elastic force of the second elastic element 122, and pulls the lower slide plate 121 to slide in the lower slide groove 12. The lower slide plate 121 drives the flexible folding metal plate 13 to slide and fold between the upper slide groove 11 and the lower slide groove 12, thereby moving the entire receiving plate to the side of the U-shaped frame 401. Before contacting the top of the vehicle body to be disassembled, the flexible folding metal plate 13 has folded to the side of the vehicle body to be disassembled, avoiding collision and damage with the vehicle body to be disassembled below. As the clamping frame 4 continues to move down, the flexible folding metal plate 13 continues to be folded and continues to move to the side of the clamping frame 4. Subsequently, the first hydraulic cylinder 201 drives the clamping frame 4 to continue moving downwards and cover the outside of the vehicle body to be disassembled, so that the support positioning mechanisms at its four corners are located around the vehicle body to be disassembled. When it is necessary to clamp and lift the vehicle body, the first hydraulic cylinder 201 retracts, the hanger 3 and the clamping frame 4 rise, causing the distance between the mounting plate 2 and the clamping frame 4 to shorten, the wire rope 14 becomes slack, and the tension on the lower slide plate 121 disappears. At this time, the compressed second elastic element 122 is released, pushing the lower slide plate 121 to slide and reset in the lower slide groove 12. The lower slide plate 121 drives the flexible folding metal plate 13 to unfold and move to the initial position. During this period, the first force-bearing inclined surface of the plate 1213 may come into contact with the bottom structure of the vehicle body, such as the wheels. The plate 1213 is forced to move downwards and compresses the fourth elastic telescopic rod 1212, causing the plate 1213 to drive the folding metal plate. The lower slide avoids the wheel area. After the plate 1213 passes the wheel area, the fourth elastic telescopic rod 1212 pulls the plate 1213 upward to reset. When the lower slide 121 is about to reset to the initial limit position, the second force-bearing inclined surface of its telescopic end will be squeezed and contracted when it contacts the bottom plate 303. Once it slides to align with the insertion hole 151, the telescopic end will quickly spring into the insertion hole 151, locking the lower slide 121 in this working position. The fully unfolded V-shaped flexible folding metal plate 13 is located on both sides under the vehicle body to catch fallen parts during subsequent transportation. During transportation, the locking effect of the elastic telescopic rod 15 and the insertion hole 151 ensures the stability of the lower slide 121 and the flexible folding metal plate 13, preventing them from sliding due to bumps. The V-shaped plate structure can guide the caught parts to the central recess, preventing them from sliding off the sides.

[0027] This invention also discloses a method of using the aforementioned end-of-life vehicle dismantling line, comprising the following steps: S1: The moving block 101 slides along the track frame 1, moving the entire hoisting device to directly above the car body to be dismantled; S2: Control the first hydraulic cylinder 201 to extend, drive the hanger 3 and the clamping frame 4 to descend as a whole. During this process, the wire rope 14 is stationary relative to the clamping frame 4, while the lower slide plate 121 moves down with the clamping frame 4, causing the wire rope 14 to generate tension on the lower slide plate 121, causing the lower slide plate 121 to move up in the lower slide groove 12 and compress the second elastic element 122. Before this, the wire rope 14 must first pull the telescopic end of the elastic telescopic rod 15 to disengage it from the insertion hole 151 of the bottom plate 303, and then pull the lower slide plate 121, so that the flexible folding metal plate 13 and the lower slide plate 121 retract and fold towards the side of the clamping frame 4. Before contacting the top of the vehicle body to be disassembled, the flexible folding metal plate 13 has retracted to the side of the vehicle body to be disassembled to avoid collision and damage with the vehicle body to be disassembled below. As the clamping frame 4 continues to move down, the flexible folding metal plate 13 continues to be folded and moves towards the side of the clamping frame 4. S3: The clamping frame 4 is lowered to a suitable height, so that the support and positioning mechanisms at its four corners are located around the vehicle body to be disassembled. Then, the four second hydraulic cylinders 501 are extended. The telescopic ends of the second hydraulic cylinders 501 push the push plate 5021. The push plate 5021 transmits the force to the L-shaped seat 5023 through the second elastic telescopic rod 5022, driving the four L-shaped seats 5023 to move in the front, rear, left and right directions of the vehicle body to be disassembled, until the horizontal part of each L-shaped seat 5023 extends under the car chassis. S4: Then, control the first hydraulic cylinder 201 to retract, driving the lifting frame 3 and the clamping frame 4 to rise as a whole. Due to the weight of the vehicle body to be disassembled, the first elastic telescopic rod 304 is compressed, which plays a buffering role. As it is lifted, the bottom of the vehicle body to be disassembled contacts the four force seats 601. The force seats 601 are pressed and drive the slider 6 to slide down on the L-shaped seat 5023. While the slider 6 moves down, it drives the swing rod 605 to rotate around the first pin on the support plate 604 through the connecting rod 606. The free end of the swing rod 605 swings until the two abutting rods 701 press tightly against the side of the vehicle body to be disassembled, thereby effectively limiting the vehicle body from both sides and preventing it from shaking during lifting. At this time, the second hydraulic cylinder 501 continues to apply a pushing force to the push plate 5021. During the movement, when the L-shaped seat 5023 comes into contact with the body of the vehicle to be disassembled, the third elastic telescopic rod 8 is compressed, and the push plate 5021 continues to retract inward relative to the L-shaped seat 5023. The push plate 5021 drives the insert block 9 to move, so that it is inserted into the corresponding slot 10 on the slider 6, thus restricting the clamping state of the vehicle to be disassembled at this time. S5: During the lifting process, as the clamping frame 4 rises, the distance between the clamping frame 4 and the mounting plate 2 shortens, and the wire rope 14 loosens. At this time, the compressed second elastic element 122 recovers, pushing the lower slide plate 121 to reset in the lower slide groove 12, thereby driving the flexible folding metal plate 13 to unfold outward to the horizontal working position. When the lower slide plate 121 is reset in place, the elastic telescopic rod 15 at its bottom extends under the action of the internal spring. Its telescopic end aligns with the insertion hole 151 and automatically springs in and locks, preventing the lower slide plate 121 from sliding during transportation. The unfolded V-shaped flexible folding metal plate 13 is located under the vehicle body to be disassembled and can catch the scattered parts that fall from the vehicle body to be disassembled during transportation bumps. S6: Then control the displacement of the moving block 101, and smoothly transfer the clamped and fixed car along the track frame 1 to the target dismantling station. After reaching the target station, control the first hydraulic cylinder 201 to slowly extend and place the car smoothly. Then control the second hydraulic cylinder 501 to retract, and drive the L-shaped seat 5023 to exit from under the car chassis, and release the support and lateral limit. Finally, the gantry 3 and the clamping frame 4 rise, ready for the next work cycle.

10. A method of using the end-of-life vehicle dismantling line according to claim 9, characterized in that, Includes the following steps: S1: The moving block (101) slides along the track frame (1) to move the entire hoisting device to the top of the vehicle body to be dismantled; S2: Control the first hydraulic cylinder (201) to extend, driving the hanger (3) and clamping frame (4) to descend as a whole. During this process, the wire rope (14) is stationary relative to the clamping frame (4), while the lower slide plate (121) moves down with the clamping frame (4), causing the wire rope (14) to generate tension on the lower slide plate (121), causing the lower slide plate (121) to move up in the lower slide groove (12) and compress the second elastic element (122). Before this, the wire rope (14) must first pull the extension and retraction of the elastic telescopic rod (15). The end is pulled out of the insertion hole (151) of the bottom plate (303), and then the lower slide plate (121) can be pulled to make the flexible folding metal plate (13) and the lower slide plate (121) retract and fold towards the side of the clamping frame (4). Before contacting the top of the vehicle body to be disassembled, the flexible folding metal plate (13) has retracted to the side of the vehicle body to be disassembled to avoid collision and damage with the vehicle body to be disassembled below. As the clamping frame (4) continues to move down, the flexible folding metal plate (13) continues to be folded and moves towards the side of the clamping frame (4). S3: The clamping frame (4) is lowered to a suitable height so that the support positioning mechanisms at its four corners are located around the vehicle body to be disassembled. Then, the four second hydraulic cylinders (501) are extended. The telescopic ends of the second hydraulic cylinders (501) push the push plate (5021). The push plate (5021) transmits the force to the L-shaped seat (5023) through the second elastic telescopic rod (5022), driving the four L-shaped seats (5023) to move in the front, rear, left and right directions of the vehicle body to be disassembled, until the horizontal part of each L-shaped seat (5023) extends into the underside of the car chassis. S4: Then control the first hydraulic cylinder (201) to retract, driving the lifting frame (3) and clamping frame (4) to rise as a whole. Due to the weight of the car body to be disassembled, the first elastic telescopic rod (304) is compressed, which plays a buffering role. As it is lifted, the bottom of the car body to be disassembled contacts the four force seats (601). The force seats (601) are pressed and drive the slider (6) to slide down on the L-shaped seat (5023). While the slider (6) moves down, it drives the swing rod (605) to rotate around the first pin on the support plate (604) through the connecting rod (606). The free end of the swing rod (605) swings until the two abutting rods (701) press tightly against the side of the car body to be disassembled, thereby effectively limiting the car body from both sides and preventing it from shaking during hoisting. At this time, the second hydraulic cylinder (501) continues to apply a pushing force to the push plate (5021). During the movement, when the L-shaped seat (5023) comes into contact with the body of the vehicle to be disassembled, the third elastic telescopic rod (8) is compressed, and the push plate (5021) continues to retract relative to the L-shaped seat (5023). The push plate (5021) drives the insert (9) to move, so that it is inserted into the corresponding slot (10) on the slider (6), thus restricting the clamping state of the vehicle to be disassembled at this time. S5: During the lifting process, as the clamping frame (4) rises, the distance between the clamping frame (4) and the mounting plate (2) shortens, and the wire rope (14) loosens. At this time, the compressed second elastic element (122) recovers, pushing the lower slide plate (121) to reset in the lower slide groove (12), thereby driving the flexible folding metal plate (13) to unfold outward to the horizontal working position. When the lower slide plate (121) is reset in place, the elastic telescopic rod (15) at its bottom extends under the action of the internal spring. Its telescopic end aligns with the insertion hole (151) and automatically springs in and locks, preventing the lower slide plate (121) from sliding during transportation. The unfolded V-shaped flexible folding metal plate (13) is located under the vehicle body to be disassembled, and can catch the scattered parts that fall from the vehicle body to be disassembled during transportation bumps. S6: Then control the displacement of the moving block (101) and smoothly transfer the clamped car to the target disassembly station along the track frame (1). After reaching the target station, control the first hydraulic cylinder (201) to slowly extend and place the car smoothly. Then control the second hydraulic cylinder (501) to retract and drive the L-shaped seat (5023) to exit from under the car chassis, and release the support and lateral limit. Finally, the gantry (3) and clamp (4) are raised to prepare for the next work cycle.
