Description

Technical Field

[0001] This invention relates to the field of end-of-life vehicle processing technology, specifically to an end-of-life vehicle dismantling equipment and its dismantling process. Background Technology

[0002] Scrapped vehicles refer to motor vehicles that have reached the national scrapping standards, or those that, while not reaching the national scrapping standards, have severely damaged engines or chassis and fail to meet national motor vehicle operation safety technical conditions or national motor vehicle pollutant emission standards. Scrapped vehicles contain a large amount of recyclable materials, such as metals, plastics, rubber, and glass. Dismantling these vehicles can effectively recycle and reuse these materials, reducing the exploitation and consumption of natural resources.

[0003] For example, Chinese patent CN115285259B discloses a waste car dismantling device, including: a base for supporting scrapped cars; a cutting mechanism connected to the top of the base and capable of moving toward the top of the base for cutting the scrapped cars into pieces; and a sorting table located on one side of the base.

[0004] The shortcomings of the aforementioned existing technical solutions are as follows: Although the solutions can crush and disassemble automobiles, when crushing the top of the car, the cutting mechanism relies on longitudinal movement to contact the top and then repeatedly cuts and crushes it to a certain extent. However, even with this process, it is difficult to ensure that the roof can be effectively separated for separate processing. The shredded parts will still be connected to the main body of the car, making it difficult to effectively separate the top and bottom of the car into two parts. This affects the disassembly of internal parts. Although other existing technologies exist to completely remove the roof from the car, the separated roof is not easy to transfer quickly and safely, requiring additional transport operations, thus reducing the overall efficiency of the car disassembly process. Furthermore, there are many parts on the car chassis, and existing technologies do not facilitate the car being flipped over so that the chassis faces upwards. When it is necessary to disassemble parts of the car chassis, the usual methods are to raise the car and then disassemble it from below, or for workers to lie flat under the car to disassemble it. Both of these methods limit the workers' disassembly space, affect the disassembly effect, and make the disassembly inconvenient. Summary of the Invention

[0013] As a further aspect of the present invention: the transmission mechanism includes a timing belt, and the ends of the two first drive screws are coaxially fixedly connected to timing pulleys, and the two timing pulleys are connected by the timing belt.

[0014] As a further embodiment of the present invention: the clamp-type cutting mechanism includes a screw drive mechanism, a lifting cutting component, and a balancing guide mechanism; the screw drive mechanism and the balancing guide mechanism are both disposed between two sets of support guide rails, the screw drive mechanism has a first slider at both ends that is slidably connected to the support guide rails, the balancing guide mechanism has a second slider at both ends that is slidably connected to the support guide rails, and the first slider and the second slider are both threadedly connected to the corresponding first drive screw, the lifting cutting component is disposed between the screw drive mechanism and the balancing guide mechanism.

[0015] As a further embodiment of the present invention: the screw drive mechanism includes a second drive screw, one end of which is rotatably connected to one of the first sliders, and the other end is equipped with a second servo motor, and the second servo motor is fixedly connected to the other first slider. Both ends of the second drive screw are threadedly connected with threaded connecting sleeves. The lifting cutting component is provided in two sets, and one end of each set of the lifting cutting component is connected to the corresponding threaded connecting sleeve, and the other end is connected to the balance guide mechanism.

[0016] As a further embodiment of the present invention: both sets of lifting cutting components include a mounting plate and a disc-shaped cutting machine.

The second hydraulic telescopic rod and the third hydraulic telescopic rod are both electrically connected to the second pressure sensing switch.

[0018] A process for dismantling end-of-life vehicles, with the following specific steps:

[0019] The first step is to move the scrapped car onto the rotating support frame and secure it using the clamping and fixing mechanism.

[0020] The second step is to cut the car roof horizontally using a clamp-type cutting mechanism, and then use a transverse drive mechanism to drive the clamp-type cutting mechanism to move the car roof horizontally away from the car along the support guide rail. After removing the roof, the internal parts of the car are disassembled.

[0021] The third step involves using the lifting connector to lift the rotating support frame, which in turn lifts the car. Once lifted, the rotating support frame flips up and down under gravity, causing the car chassis to face upwards. Then, the parts on the car chassis are disassembled.

[0022] The beneficial effects of this invention are:

[0023] 1. This invention relies on a second drive screw to drive two sets of laterally distributed disc-shaped cutting machines to move laterally, thereby facilitating the direct lateral cutting of the roof of a scrapped car. After the two sets of disc-shaped cutting machines come together, the corresponding second and fourth hydraulic telescopic rods automatically retract, thereby raising the cut car roof to abut against the crossbar, achieving fixed clamping of the roof and effective separation from the bottom of the car, facilitating subsequent disassembly.

[0024] 2. In this invention, after the roof rises and contacts the crossbar, the first pressure sensor switch on the crossbar generates feedback, causing the first drive screw to drive the distributed first and second sliders to move laterally along the support guide rail. In this way, the first and second sliders drive the raised and clamped roof to move laterally away from the car body, making it easier for workers to disassemble the parts in the car's interior space. This avoids the danger of the cut roof hanging above and falling and hitting the maintenance workers. Moreover, the process is completed automatically without manual operation, improving the overall disassembly efficiency.

[0025] 3. When it is necessary to disassemble the parts of the car chassis, the present invention controls the first hydraulic telescopic rod to drive the lifting cross plate to rise. The lifting cross plate then drives the rotating support frame supporting the car to rise. After the rotating support frame is raised to the corresponding height, the cylindrical cross bar is pressed against the pressing inclined block, causing the pressing inclined block to release the horizontal locking plate from the rotating support frame, thereby unlocking. In this way, the rotating support frame can carry the car up and down under the action of gravity, so that the chassis can automatically rotate upward, which facilitates the disassembly of the parts on the chassis.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1-5As shown, a scrapped car dismantling device includes a support rail 1 and a support column 2. Two sets of support rails 1 are arranged in parallel, and each set of support rails 1 has a support column 2 fixedly connected to both ends, providing support for the support rails 1. The device also includes a lifting support component and a cutting assembly. The lifting support component includes a rotating support frame 8 and lifting connectors. Two sets of lifting connectors are provided and respectively connected to the lower part of the support rails 1. The rotating support frame 8 is rotatably positioned between the telescopic ends of the two sets of lifting connectors. The rotating support frame 8 is used to support and place scrapped cars. The rotating support frame 8 has a hollow frame structure in the middle, with clamping and fixing mechanisms symmetrically distributed on both sides of the rotating support frame 8, and the upper surface of the rotating support frame 8 is inclined. That is, one side is higher and the other side is lower. When the car moves onto the rotating support frame 8, it is fixed by the clamping and fixing mechanism. Then, the rotating support frame 8 is raised by the lifting connector. Since the car is fixed above the rotating support frame 8, the upper part is heavier and the upper surface is inclined, which makes it easier for the car to be tilted to a lower position. After the rotating support frame 8 is raised, its bottom loses ground support and is suspended in the air. Then, the rotating support frame 8 can automatically tilt under the action of gravity, so that the car can be flipped over and the chassis is facing upward. It should be noted that even if the upper surface of the rotating support frame 8 is not set as a slope, since the car is mounted on the rotating support frame 8 and the weight is evenly distributed on both sides of the central axis, it will inevitably tilt to one side.

[0035] The cutting assembly includes a clamp-type cutting mechanism and a transverse drive mechanism. The transverse drive mechanism is mounted on the support guide rail 1, and the clamp-type cutting mechanism is mounted between the two support guide rails 1. The clamp-type cutting mechanism is connected to the transverse drive mechanism.

[0036] When disassembly is required, the clamp-type cutting mechanism will cut off the top of the car laterally, and the car top cut off by the transverse drive mechanism will be moved laterally to facilitate the disassembly of the internal parts of the car by the staff.

[0037] In some specific implementation plans, such as Figure 1 As shown, both sets of lifting connecting parts include lifting horizontal plates 7. A rotating support frame 8 is rotatably connected between the two lifting horizontal plates 7 via a rotating shaft. The rotating shaft is located at the center line of the rotating support frame 8. Each lifting horizontal plate 7 has a first hydraulic telescopic rod 6 vertically fixedly connected to both ends. The end of the first hydraulic telescopic rod 6 away from the lifting horizontal plate 7 is fixedly connected to the corresponding support guide rail 1. Each of the distributed first hydraulic telescopic rods 6 is controlled by a control switch and has the same specifications, which facilitates simultaneous extension and retraction, thereby making it easy to drive the rotating support frame 8 to move up and down by relying on the lifting horizontal plate 7.

[0038] In some specific implementations, to prevent the rotating support frame 8 from rotating immediately after leaving the ground, causing its edges to hit the ground, a linkage locking mechanism is installed between the lifting horizontal plate 7 and the rotating support frame 8, such as... Figure 4 and Figure 5 As shown, the linkage locking mechanism includes a pressing inclined block 17, a transverse locking plate 28, and a connecting spring 27. The transverse locking plate 28 extends transversely through the lifting horizontal plate 7 and can slide relative to the lifting horizontal plate 7. The end of the transverse locking plate 28 away from the rotating support frame 8 is fixedly connected to the pressing inclined block 17. A cylindrical crossbar 16 that cooperates with the pressing inclined block 17 is fixedly connected to the support column 2 near the lifting horizontal plate 7. The cylindrical crossbar 16 is higher than the position of the lifting horizontal plate 7. The connecting spring 27 is connected between the lifting horizontal plate 7 and the transverse locking plate 28. The end of the rotating support frame 8 near the lifting horizontal plate 7 is provided with a slot 26 that cooperates with the transverse locking plate 28.

[0039] In its initial state, the transverse locking plate 28 is inserted into the slot 26, locking the relative positions of the rotating support frame 8 and the lifting horizontal plate 7, preventing relative movement. When the lifting horizontal plate 7, carrying the rotating support frame 8, rises to the position of the cylindrical horizontal bar 16, the cylindrical horizontal bar 16 presses against the inclined surface of the pressing block 17, causing the pressing block 17 to be subjected to a transverse pressing force. Thus, the pressing block 17 drives the transverse locking plate 28 to move laterally and disengage. During this process, the limiting spring 27 is compressed, and finally the transverse locking plate 28 disengages from the slot 26, unlocking the rotating support frame 8. The rotating support frame 8 can then be tilted up and down by the weight of the car placed on the upper layer.

[0040] In some specific implementation schemes, in order to facilitate the lateral translation of the clamp-type cutting mechanism along the support guide rail 1, combined with Figures 1 to 3 As shown, the transverse drive mechanism includes a first drive screw 25 and a first servo motor 3. There are two first drive screws 25, which are rotatably connected to the corresponding support rails 1. The first servo motor 3 is fixedly connected to the end of one set of support rails 1, and the spindle end of the first servo motor 3 is connected to the corresponding first drive screw 25. A transmission mechanism is provided between the two first drive screws 25, and a clamp-type cutting mechanism is provided between the two first drive screws 25.

[0041] The transmission mechanism includes a timing belt 5, and timing pulleys 4 are coaxially fixedly connected to the ends of the two first drive screws 25. The two timing pulleys 4 are connected to each other by the timing belt 5.

[0042] When the first servo motor 3 drives the corresponding first drive screw 25 to rotate, the first drive screw 25 drives the other first drive screw 25 to rotate by means of the combination of the synchronous pulley 4 and the synchronous belt 5.

[0043] In some specific implementations, to facilitate the effective lateral cutting and separation of the car roof, the clamp-type cutting mechanism includes a screw drive mechanism, a lifting cutting component, and a balancing guide mechanism. Both the screw drive mechanism and the balancing guide mechanism are positioned between two sets of support rails 1. The screw drive mechanism has a first slider 20 at both ends that is slidably connected to the support rail 1. The balancing guide mechanism has a second slider 24 at both ends that is slidably connected to the support rail 1. Both the first slider 20 and the second slider 24 are threadedly connected to a corresponding first drive screw 25, which passes through both the first slider 20 and the second slider 24. The lifting cutting component is positioned between the screw drive mechanism and the balancing guide mechanism.

[0044] The screw drive mechanism includes a second drive screw 13. One end of the second drive screw 13 is rotatably connected to one of the first sliders 20, and the other end is equipped with a second servo motor 21. The second servo motor 21 is fixedly connected to the other first slider 20. The second servo motor 21 is used to drive the second drive screw 13 to rotate. Both ends of the second drive screw 13 are threadedly connected to threaded connecting sleeves 22. The second drive screw 13 is provided with two opposite threads. The two threaded connecting sleeves 22 are respectively connected to one thread. In this way, when the second drive screw 13 rotates, the two threaded connecting sleeves 22 can move closer to each other or separate. Two sets of lifting cutting components are provided. One end of each set of lifting cutting components is connected to the corresponding threaded connecting sleeve 22, and the other end is connected to the balance guide mechanism.

[0045] The balance guide mechanism includes a guide rod 10 and a sliding sleeve 23. The guide rod 10 is fixedly connected between two second sliders 24. Two sliding sleeves 23 are provided and are slidably connected to both ends of the guide rod 10. The sliding sleeves 23 are aligned with the threaded connecting sleeves 22. A crossbar 12 is fixedly connected between the sliding sleeves 23 and the aligned threaded connecting sleeves 22. A first pressure sensing switch electrically connected to the transverse drive mechanism is distributed at the bottom of the crossbar 12. Specifically, the first pressure sensing switch activates the first servo motor 3 in the transverse drive mechanism. The two sliding sleeves 23 are respectively connected to the lifting and cutting components.

[0046] In some specific implementations, both sets of lifting cutting components include a mounting plate 14 and a disc-shaped cutting machine 15. One end of the mounting plate 14 is fixedly connected to a second hydraulic telescopic rod 9, and the end of the second hydraulic telescopic rod 9 away from the mounting plate 14 is fixedly connected to a corresponding threaded connecting sleeve 22. The other end of the mounting plate 14 is fixedly connected to a third hydraulic telescopic rod 29, and the end of the third hydraulic telescopic rod 29 away from the mounting plate 14 is fixedly connected to a corresponding sliding sleeve 23. Multiple disc-shaped cutting machines 15 are provided and are distributed laterally at equal intervals on the mounting plate 14.

[0047] When both mounting plates 14 are initially positioned above the front and rear ends of the rotating support frame 8, the second hydraulic telescopic rods 9 and the third hydraulic telescopic rods 29 can be controlled to extend synchronously, causing the mounting plates 14 to descend along with the distributed disc-shaped cutting machines 15. Then, the second servo motor 21 is activated, which drives the second drive screw 13 to rotate, causing the two threaded connecting sleeves 22 to move closer together towards the center. In this way, the threaded connecting sleeves 22 drive the mounting plates 14 to move laterally closer together towards the center, making it easier to cut the various pillars of the car roof using the two laterally distributed disc-shaped cutting machines 15. The horizontal cutting is achieved, and the horizontal bar 12 drives the sliding sleeve 23 to move horizontally in sync. When the two sets of disc cutting machines 15 cut horizontally to the middle position of the car and achieve the separation of the roof, the second hydraulic telescopic rod 9 and the third hydraulic telescopic rod 29 are controlled to retract. In this way, the two mounting plates 14 can push up the cut roof and drive it to contact the horizontal bar 12. The first pressure sensing switch on the horizontal bar 12 will generate a sense and start the first servo motor 3, thereby causing the first slider 20 and the second slider 24 to drive the guide rod 10 and the second drive screw 13 to move along the support guide rail 1.

[0048] In order to enable the second hydraulic telescopic rod 9 and the third hydraulic telescopic rod 29 to retract automatically, a limit block group 11 is fixedly connected to the middle position of the guide rod 10, and a second pressure sensing switch is installed on the side of the limit block group 11 near the sliding sleeve 23. The retraction control circuits of the second hydraulic telescopic rod 9 and the third hydraulic telescopic rod 29 are both electrically connected to the second pressure sensing switch.

[0049] When the sliding sleeve 23 slides to the middle position of the guide rod 10, the two sets of disc-shaped cutting machines 15 will cut horizontally to the middle position of the car roof, separating it from the bottom. At this time, the sliding sleeve 23 will contact the limit block group 11, causing the second pressure sensing switch to generate feedback. The second pressure sensing switch will then cause the second hydraulic telescopic rod 9 and the third hydraulic telescopic rod 29 to retract, thereby automatically raising the mounting plate 14 and the cut roof.

[0050] In some specific implementations, both sets of clamping and fixing mechanisms include a fourth hydraulic telescopic rod 19 and a fixed clamping plate 18. The two fourth hydraulic telescopic rods 19 are symmetrically distributed on both sides of the rotating support frame 8 and are fixedly installed. The two fixed clamping plates 18 are respectively fixedly connected to the telescopic ends of the corresponding fourth hydraulic telescopic rods 19, and the fixed clamping plates 18 are provided with protruding teeth. When the car is mounted on the rotating support frame 8, the two fourth hydraulic telescopic rods 19 are controlled to extend, thereby achieving fixed clamping of the car.

[0051] A process for dismantling end-of-life vehicles, implemented using the aforementioned end-of-life vehicle dismantling equipment, comprises the following specific steps:

[0052] The first step is to move the scrapped car onto the rotating support frame 8 and fix it in place using the clamping and fixing mechanism.

[0053] The second step is to cut the car roof horizontally using a clamp-type cutting mechanism, and clamp the cut car roof in place. Then, the clamp-type cutting mechanism is driven by a transverse drive mechanism to move the car roof horizontally along the support guide rail 1 and detach it from the car. After removing the roof, the internal parts of the car are disassembled.

[0054] The third step involves lifting the rotating support frame 8 using the lifting connector, which in turn lifts the car. Once lifted, the rotating support frame 8 flips up and down under gravity, causing the car chassis to face upwards. Then, the parts on the car chassis are disassembled.

[0055] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios:

[0056] First, the car frame is positioned on the rotating support frame 8. The two fourth hydraulic telescopic rods 19 are extended to secure the car. Then, the second and third hydraulic telescopic rods 9 and 29 are extended synchronously, causing the mounting plate 14 to descend with the distributed disc-shaped cutters 15. Next, the second servo motor 21 is activated, which drives the second drive screw 13 to rotate, causing the two threaded connecting sleeves 22 to move towards the center. The threaded connecting sleeves 22 then drive the mounting plate 14 to move laterally towards the center, facilitating the cutting of the car roof supports by the two laterally distributed disc-shaped cutters 15, achieving lateral cutting. The crossbar 12 drives the sliding sleeve 23 to move laterally. When the two disc-shaped cutters 15 have cut laterally to the middle of the car, the roof is separated.

[0057] At this time, the sliding sleeve 23 slides to the middle position of the guide rod 10 and comes into contact with the limit block group 11, causing the second pressure sensor switch to generate feedback. The second pressure sensor switch then causes the second hydraulic telescopic rod 9 and the third hydraulic telescopic rod 29 to retract, thereby realizing the automatic upward lifting of the mounting plate 14. The raised roof comes into contact with the crossbar 12, and the first pressure sensor switch on the crossbar 12 generates a sensor, causing the first servo motor 3 to start. This causes the first slider 20 and the second slider 24 to drive the guide rod 10 and the second drive screw 13 to move along the support guide rail 1, making it easier for staff to disassemble the internal parts of the car.

[0058] After the internal parts of the car are disassembled, the first hydraulic telescopic rod 6 is extended and retracted, causing the lifting cross plate 7 to lift the rotating support frame 8. When the lifting cross plate 7 and the rotating support frame 8 are raised to the position of the cylindrical cross bar 16, the cylindrical cross bar 16 is pressed against the inclined surface of the pressing wedge 17, causing the pressing wedge 17 to be subjected to a lateral pressing force. In this way, the pressing wedge 17 drives the transverse locking plate 28 to move laterally and disengage. During this process, the limiting spring 27 is compressed, and finally the transverse locking plate 28 disengages from the slot 26, realizing the unlocking of the rotating support frame 8. The rotating support frame 8 can then be tilted up and down by the weight of the car placed on the upper layer.

[0059] The foregoing has described several embodiments of the present invention in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of the invention. All equivalent variations and improvements made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
