Description

Technical Field

[0001] This invention relates to the field of lifting container technology, specifically a vertical lifting container and its conveying method that is transported by visual intelligent control. Background Technology

[0002] Vertical lift containers are a type of high-density, intelligent warehousing equipment. They mainly use a motor-driven chain to move a lifting plate vertically up and down inside the container, transporting pallets carrying goods to a designated height partition position, thus achieving automatic storage and retrieval of goods.

[0003] With the development of intelligent warehousing technology, vision control systems have been introduced into vertical lifting containers. Through real-time scanning and positioning by vision modules, the swaying error that may be caused by chain transmission is compensated to ensure that the lifting platform stops precisely at the target height.

[0004] During the long-term operation of vertical lift containers, the chain, as the main load-bearing and transmission component, bears the entire weight of the lifting platform and the goods on it. Due to frequent loading and unloading of goods, fatigue wear of the chain, and possible uneven stress, the chain is at risk of breaking. Once the chain breaks, the lifting platform will fall rapidly under the action of gravity, which will not only damage the pallet and goods, but may also damage the internal structure of the container.

[0005] Existing technologies for fall protection typically employ steel wire ropes. When the chain breaks or the speed of the lifting platform exceeds a safety threshold, the steel wire rope is locked by centrifugal force. However, this locking method is simplistic and relies entirely on the steel wire rope to bear the entire impact load. When the lifting platform carrying heavy loads falls, the steel wire rope will experience tremendous impact tension at the moment of locking, which can easily cause the internal strands of the steel wire rope to break or the rope ends to loosen, leading to locking failure. Summary of the Invention

[0006] The purpose of this invention is to provide a vertical lifting container and its conveying method controlled by visual intelligence, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A vertical lifting container controlled by visual intelligence includes:

[0009] The cabinet, and the top plate installed on the cabinet, with symmetrically distributed rotating rods installed inside the cabinet, chain teeth connected to the rotating rods, and chains meshing on the chain teeth;

[0010] Also includes:

[0011] A lifting plate is connected to the chain, and a buffer assembly is provided on the lifting plate, with a connecting plate connected to the buffer assembly;

[0012] A centrifugal limiting mechanism is installed on the top plate, and a steel wire rope connected to the connecting plate is connected to the centrifugal limiting mechanism. The centrifugal limiting mechanism can lock the position of the steel wire rope when the speed of the connecting plate is abnormal.

[0013] A trigger locking mechanism is installed inside the cabinet and connected to the connecting plate. The trigger locking mechanism can be activated when there is relative displacement between the connecting plate and the lifting plate to lock the position of the lifting plate.

[0014] As a further aspect of the present invention: the buffer assembly includes a movable rod slidably mounted on the lifting plate, the movable rod being connected to the connecting plate, a first limiting ring and a second limiting ring being connected to the movable rod, the second limiting ring being in contact with the lifting plate, and a first spring being sleeved on the movable rod, the two ends of the first spring being in contact with the first limiting ring and the lifting plate respectively.

[0015] As a further embodiment of the present invention: the centrifugal limiting mechanism includes a fixed plate symmetrically connected to the top plate, a winding roller is rotatably mounted on the fixed plate, and the wire rope is wound on the winding roller;

[0016] It also includes a rotating assembly and a fitting assembly disposed on the take-up roller.

[0017] As a further embodiment of the present invention: the rotating assembly includes a rotating disk slidably mounted on the take-up roller, the rotating disk having a plurality of grooves equidistantly distributed around the circumference, a sliding block being slidably mounted in the groove, a limit wheel being rotatably mounted on the sliding block, and a conical ring being connected to the fixed plate and engaging with the limit wheel.

[0018] As a further embodiment of the present invention: the fitting assembly includes a fixed ring connected to the end of the take-up roller, a limiting plate connected to the rotating disk, a third spring sleeved on the take-up roller, the two ends of the third spring respectively abutting against the limiting plate and the fixed ring, and a fixed plate connected to the top plate that abuts against the limiting plate.

[0019] As a further embodiment of the present invention: the triggering locking mechanism includes guide columns connected to the cabinet body and symmetrically distributed, a plurality of guide blocks equally distributed on the guide columns, a rotating sleeve sleeved on the guide columns is rotatably mounted on the lifting plate, and a fixing block that abuts against the guide blocks is connected to the inner wall of the rotating sleeve.

[0020] It also includes a guide assembly and a follower assembly disposed on the lifting plate and connected to the rotating sleeve.

[0021] As a further embodiment of the present invention: the guiding component includes a spiral groove and an annular groove formed on the outer circumference of the rotating sleeve, a sliding sleeve is slidably attached to the rotating sleeve, and a limiting block is connected to the inner wall of the sliding sleeve and slidably engaged with the spiral groove and the annular groove.

[0022] As a further embodiment of the present invention: the follower component includes a support rod connected to the connecting plate, a movable plate connected to the sliding sleeve is slidably mounted on the support rod, a support ring that abuts against the movable plate is connected to the end of the support rod, and a second spring is sleeved on the rotating sleeve, with the two ends of the second spring abutting against the movable plate and the connecting plate respectively.

[0023] A method for conveying a vertically lifting container using visual intelligent control includes the following steps:

[0024] Step 1: The chain teeth are rotated by the rotating rod, and the lifting plate is moved by the chain;

[0025] Step 2: When the chain breaks, the lifting plate descends rapidly and drives the connecting plate to move through the buffer assembly;

[0026] Step 3: The connecting plate controls the movement of the centrifugal limit mechanism through the wire rope, and locks the position of the wire rope when the speed reaches the set value, thereby locking the position of the lifting plate in the first stage.

[0027] Step 4: The connecting plate will also undergo relative displacement with the lifting plate, and under the action of the trigger locking mechanism, the position of the lifting plate will be locked in a secondary manner.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] This invention achieves dual protection of centrifugal locking and mechanical resistance locking of the wire rope through the coordinated operation of the centrifugal limiting mechanism and the trigger locking mechanism, as well as multi-level buffering and dispersion of the falling impact force. When the chain breaks and the lifting plate falls rapidly, the buffer component provides initial buffering of the falling impact. At the same time, under the action of centrifugal force, the limiting plate and the fixed plate engage with each other to complete the first-level locking of the lifting plate. In this way, under the buffering effect, the wire rope is prevented from directly bearing the entire falling force under rigid impact, reducing the instantaneous peak tension on the wire rope and improving the reliability of locking.

[0030] During the primary locking process, the cooperation between the fixed block and the guide block provides a secondary locking effect for the lifting plate. When the fixed block slides along the spiral section of the guide block, it can buffer the descent. When the fixed block enters the annular section, multiple fixed blocks simultaneously abut against the end face of the corresponding guide block, and the position of the lifting plate no longer changes. In this way, the impact stress is dispersed through the contact cooperation between the fixed block and the guide block, achieving a secondary mechanical locking of the lifting plate. Furthermore, the force concentrated on the wire rope is dispersed, preventing the wire rope from breaking due to excessive tension, thereby further improving the safety of loading and unloading goods.

[0042] 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.

[0043] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0044] Please see Figures 1-10 In this embodiment of the invention, a vertically lifting container controlled by visual intelligence includes:

[0045] Cabinet 1, and top plate 2 installed on cabinet 1. Rotating rods 3 are symmetrically distributed inside cabinet 1. Chain teeth are connected to the rotating rods 3, and chains 4 are engaged on the chain teeth.

[0046] Also includes:

[0047] The lifting plate 5 is connected to the chain 4. A buffer assembly is provided on the lifting plate 5, and a connecting plate 11 is connected to the buffer assembly.

[0048] A centrifugal limiting mechanism is provided on the top plate 2. A steel wire rope 19 connected to the connecting plate 11 is connected to the centrifugal limiting mechanism. The centrifugal limiting mechanism can lock the position of the steel wire rope 19 when the speed of the connecting plate 11 is abnormal.

[0049] A trigger locking mechanism is installed inside the cabinet 1 and connected to the connecting plate 11. The trigger locking mechanism can be activated when the connecting plate 11 and the lifting plate 5 are in relative positions to lock the position of the lifting plate 5.

[0050] Specifically, when storing goods in a container, the goods are usually quite heavy. With prolonged use, chain 4 is prone to breakage due to uneven stress, causing the lifting platform 5 to fall and damage the goods. Therefore, in the event of chain 4 breakage, the position of the lifting platform 5 needs to be quickly locked. During normal operation, the centrifugal limit mechanism controls the steel wire rope 19 to move synchronously with the lifting platform 5 and maintain a slight tension. At this time, chain 4 is responsible for transmitting force, while the steel wire rope 19 does not provide force. If chain 4 breaks, the lifting platform 5 and the goods on it will... Under the influence of gravity, the object falls rapidly, causing the buffer assembly to move. The buffer assembly transmits the force to the wire rope 19 through the connecting plate 11, causing the centrifugal limiting mechanism to move. Under the action of the centrifugal limiting mechanism, the wire rope 19 is locked, thus providing a primary locking effect to the lifting plate 5 through the connecting plate 11 and the buffer assembly. At the same time, the connecting plate 11 will undergo relative displacement with the lifting plate 5, driving the trigger locking mechanism to move. Under the action of the trigger locking mechanism, the impact force generated by the fall is buffered and dispersed, and a secondary locking effect is provided to the lifting plate 5, thereby ensuring that the goods are not damaged.

[0051] The cabinet 1 has multiple partitions installed on both sides for placing goods. The lifting plate 5 is equipped with a vision module. When the lifting plate 5 carries a pallet containing goods, it can be raised to a specified height by controlling the chain 4. Since the chain 4 may shake during operation, it may cause deviations in the actual lifting and lowering height of the lifting plate 5. At this time, the vision module performs a visual scan and controls the chain 4 to move accordingly, thereby ensuring that the lifting plate 5 moves to the specified height.

[0052] Please see Figures 2-4 , Figure 6 , Figure 8The buffer assembly includes a movable rod 9 slidably mounted on the lifting plate 5. The movable rod 9 is connected to the connecting plate 11. A first limiting ring 901 and a second limiting ring 902 are connected to the movable rod 9. The second limiting ring 902 abuts against the lifting plate 5. A first spring 10 is sleeved on the movable rod 9. The two ends of the first spring 10 abut against the first limiting ring 901 and the lifting plate 5, respectively.

[0053] Please see Figure 2 , Figure 3 , Figure 9 , Figure 10 The centrifugal limiting mechanism includes a fixed plate 17 symmetrically connected to the top plate 2, a take-up roller 18 rotatably mounted on the fixed plate 17, and a wire rope 19 wound around the take-up roller 18; it also includes a rotating assembly and an engaging assembly disposed on the take-up roller 18, the rotating assembly including a rotating disk 21 slidably mounted on the take-up roller 18, the rotating disk 21 having a plurality of circumferentially equidistant grooves 2101 formed thereon, and sliding blocks 22 slidably mounted in the grooves 2101. A limiting wheel 2201 is rotatably mounted on the top plate 22. A conical ring 20 that abuts against the limiting wheel 2201 is connected to the fixed plate 17. The fitting assembly includes a fixed ring 1801 connected to the end of the take-up roller 18. A limiting disc 23 is connected to the rotating disk 21. A third spring 25 is sleeved on the take-up roller 18. The two ends of the third spring 25 abut against the limiting disc 23 and the fixed ring 1801, respectively. A fixed disc 24 that abuts against the limiting disc 23 is connected to the top plate 2.

[0054] Please see Figure 9 , Figure 10 In detail, the end faces of both the limiting plate 23 and the fixed plate 24 are convex, and their protrusions can abut against each other. The conical ring 20 is conical. A guide wheel 16 is installed on the lifting plate 5. Under the guidance of the guide wheel 16, interference between the wire rope 19 and the goods can be avoided. In the initial state, the winding roller 18 is not rotating, the limiting wheel 2201 is not subjected to centrifugal force, and the limiting plate 23 and the rotating plate 21 are located at the end of their strokes near the fixed plate 17, so that the limiting plate 23 and the fixed plate 24 are in contact with each other. With the fixed plate 24 in a separated state, the distance between the four sliding blocks 22 is at its minimum, so that the limiting wheel 2201 is located on the side of the conical ring 20 close to the fixed plate 17. In this state, the distance between the limiting plate 23 and the fixed ring 1801 is at its maximum. The extension of the third spring 25 in its natural state is greater than the maximum distance between the limiting plate 23 and the fixed ring 1801. Therefore, the third spring 25 is in a pre-compressed state and always provides the limiting plate 23 with a thrust in the direction away from the fixed plate 24.

[0055] Since the wire rope 19 does not provide tension to the connecting plate 11, the distance between the connecting plate 11 and the lifting plate 5 is the smallest, so that the second limiting ring 902 and the lifting plate 5 are in abutting state. In this state, the distance between the first limiting ring 901 and the lifting plate 5 is the largest. The elongation of the first spring 10 in its natural state is greater than the maximum distance between the first limiting ring 901 and the lifting plate 5. Therefore, the first spring 10 is in a pre-compressed state and always provides the first limiting ring 901 with a thrust in the direction away from the lifting plate 5.

[0056] A motor is installed on the top plate 2 to drive the rotation of the winding roller 18. When the lifting plate 5 is storing and retrieving goods normally, the motor controls the rotation of the winding roller 18, so that the wire rope 19 moves synchronously with the lifting plate 5, thereby controlling the wire rope 19 to be in a slightly taut state.

[0057] If chain 4 breaks, lifting plate 5 will fall rapidly. The acceleration generated by the falling lifting plate 5 will cause the first spring 10 to push the first limit ring 901, which will drive the movable rod 9 to move rapidly with the lifting plate 5. Meanwhile, the connecting plate 11 is still being pulled by the wire rope 19. Therefore, there will be a relative displacement between the lifting plate 5 and the connecting plate 11, and the first spring 10 will be further compressed to achieve initial buffering of the falling impact.

[0058] Simultaneously, the connecting plate 11 pulls the wire rope 19, causing the wire rope 19 to quickly pull the winding roller 18 to rotate. The rotation speed of the winding roller 18 will increase sharply, and the rotating disk 21 will rotate synchronously with the winding roller 18. At this time, the centrifugal force on the sliding block 22 increases, causing the sliding block 22 to slide along the slide groove 2101 away from the axis of the winding roller 18. The limiting wheel 2201 on the sliding block 22 will slide along the inner wall of the conical ring 20 away from the fixed plate 17, thereby driving the rotating disk 21 and the limiting disk 23 to move towards the fixed disk 24 as a whole, and compressing the third spring 25. Finally, the protrusion of the limiting disk 23 and the protrusion of the fixed disk 24 are engaged and abutted against each other, the rotation of the winding roller 18 is locked, and the wire rope 19 cannot be pulled out further, thus achieving the first-level locking of the lifting plate 5.

[0059] If the lifting plate 5 is located near the bottom of the cabinet 1 and the chain 4 breaks, the lifting plate 5 can fall to a relatively small height, making it difficult to trigger the centrifugal locking between the limiting plate 23 and the fixed plate 24. The movable rod 9 extends out from the lower side of the lifting plate 5 and will first contact the bottom of the cabinet 1, locking the position of the first limiting ring 901. The first spring 10 provides a buffering force to the lifting plate 5, thereby decelerating the lifting plate 5 until it stops falling. In this way, when the lifting plate 5 is at a higher position, the position of the wire rope 19 can be locked to protect the lifting plate 5 and the goods. When the lifting plate 5 is at a lower position, the elastic buffering method can prevent the lifting plate 5 from having a hard collision with the bottom of the cabinet 1.

[0060] Please participate Figures 2-8 The trigger locking mechanism includes guide posts 6 connected within the cabinet 1 and symmetrically distributed, with multiple guide blocks 601 evenly distributed on the guide posts 6. A rotating sleeve 7, sleeved on the guide posts 6, is rotatably mounted on the lifting plate 5. A fixing block 8, which abuts against the guide blocks 601, is connected to the inner wall of the rotating sleeve 7. The mechanism also includes a guide assembly and a follower assembly disposed on the lifting plate 5 and connected to the rotating sleeve 7. The guide assembly includes a spiral groove 701 and an annular groove 702 formed on the outer circumference of the rotating sleeve 7. A sliding sleeve 14 is slidably mounted on the axial direction. A limiting block 1401 is connected to the inner wall of the sliding sleeve 14 and slides into the spiral groove 701 and the annular groove 702. The follower assembly includes a support rod 12 connected to the connecting plate 11. A movable plate 13 connected to the sliding sleeve 14 is slidably mounted on the support rod 12. A support ring 1201 that abuts against the movable plate 13 is connected to the end of the support rod 12. A second spring 15 is sleeved on the rotating sleeve 7. The two ends of the second spring 15 abut against the movable plate 13 and the connecting plate 11, respectively.

[0061] Furthermore, there are multiple guide blocks 601 distributed at equal intervals along the axial direction of the guide post 6, and each guide block 601 is composed of two segments, namely a spiral segment and an annular segment. The fixing blocks 8 are also distributed at equal intervals, and the distance between adjacent fixing blocks 8 is equal to the distance between adjacent guide blocks 601.

[0062] In the initial state, under the action of the first spring 10, the distance between the connecting plate 11 and the lifting plate 5 is maximized. At this time, the distance between the movable plate 13 and the sliding sleeve 14 and the connecting plate 11 is maximized, and the movable plate 13 and the support ring 1201 are in abutment state, so that the limiting block 1401 is located at the end of the stroke of the spiral groove 701 away from the annular groove 702. The extension of the second spring 15 in its natural state is greater than the maximum distance between the movable plate 13 and the connecting plate 11. Therefore, the second spring 15 is in a pre-compressed state and always provides the movable plate 13 with a thrust in the direction away from the connecting plate 11. Under the action of the limiting block 1401 and the spiral groove 701, the angle of the rotating sleeve 7 is locked. In this state, the fixed block 8 and the guide block 601 are in a misaligned state, that is, the fixed block 8 will not interfere with the axial sliding of the rotating sleeve 7 along the guide post 6.

[0063] When chain 4 breaks, lifting plate 5 falls rapidly under the action of gravity. Steel wire rope 19 provides the main pulling force under the action of centrifugal limiting mechanism. It drives the movable rod 9 to move through connecting plate 11, thereby compressing the first spring 10 and realizing the initial buffering of the falling impact. Relative displacement occurs between connecting plate 11 and lifting plate 5, that is, connecting plate 11 moves away from lifting plate 5 and drives support rod 12 to move away from lifting plate 5 in sync.

[0064] At this time, under the action of the second spring 15, the movable plate 13 is controlled to maintain its contact with the support ring 1201 and moves synchronously with the connecting plate 11. The movable plate 13 drives the sliding sleeve 14 to slide along the axis of the rotating sleeve 7. The limiting block 1401 on the inner wall of the sliding sleeve 14 slides along the spiral groove 701 towards the annular groove 702. Under the cooperation of the limiting block 1401 and the spiral groove 701, the rotating sleeve 7 rotates, driving the fixed block 8 to rotate synchronously, so that it moves to the position where it is directly aligned with the guide block 601 on the guide post 6.

[0065] Since the lifting plate 5 is still in a downward state, the fixed block 8 contacts the spiral section of the guide block 601 and slides along the inclined trajectory of the spiral section. Under the action of the spiral section of the guide block 601 and the fixed block 8, the lifting plate 5 can be buffered and decelerated during its downward process.

[0066] When the fixed block 8 disengages from the spiral section and moves to the annular section of the guide block 601, the fixed block 8 abuts against the annular end face of the guide block 601, the downward movement of the lifting plate 5 is stopped, and the height no longer changes. Since multiple fixed blocks 8 abut against the corresponding guide blocks 601 at the same time, the downward impact force is evenly distributed to multiple contact points, avoiding stress concentration and improving the reliability of locking.

[0067] During this process, the centrifugal locking action has been completed between the limiting plate 23 and the fixed plate 24, and the positions of the wire rope 19 and the connecting plate 11 are locked. Under the buffering action of the first spring 10, the lifting plate 5 can still move down a small distance relative to the connecting plate 11, so that the fixed block 8 can smoothly slide over the spiral section of the guide block 601 and enter the annular section, realizing the abutting cooperation between the fixed block 8 and the guide block 601. In this way, the impact stress is dispersed by the abutting cooperation between the fixed block 8 and the guide block 601, realizing the secondary mechanical locking of the lifting plate 5, and further dispersing the force concentrated on the wire rope 19, avoiding the wire rope 19 from breaking due to excessive tension, thereby further improving the safety of loading and unloading goods.

[0068] A method for conveying a vertically lifting container using visual intelligent control includes the following steps:

[0069] Step 1: The chain teeth are rotated by rotating rod 3, and the lifting plate 5 is moved by chain 4;

[0070] Step 2: When chain 4 breaks, lifting plate 5 descends rapidly and drives connecting plate 11 to move through buffer assembly;

[0071] Step 3: The connecting plate 11 controls the movement of the centrifugal limiting mechanism through the wire rope 19, and locks the position of the wire rope 19 when the speed reaches the set value, thereby locking the position of the lifting plate 5 in the first stage.

[0072] Step 4: The connecting plate 11 will also undergo relative displacement with the lifting plate 5, and under the action of the trigger locking mechanism, the position of the lifting plate 5 will be locked in a secondary manner.
