Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, and in particular to a transportation device for the production and processing of suspension springs. Background Technology

[0002] As a core component of the automotive suspension system, the suspension spring plays a crucial role in the vehicle's driving performance. It is typically made of high-quality spring steel of a specific grade, precision-machined into a helical structure. During vehicle operation, uneven road surfaces cause the wheels to experience impact forces. The suspension spring, with its inherent elastic properties, converts this impact energy into stored elastic potential energy and releases it as needed.

[0003] Suspension spring production involves multiple processes, including material preparation, coiling, heat treatment, high-pressure treatment, and surface treatment. Different transportation equipment is used between each process, such as forklifts, conveyor belts, overhead cranes, and overhead conveyors.

[0004] Patent publication number CN221719195U discloses a transfer fixture for primary spring assemblies in rail transit, comprising: a storage frame with an open top, wherein the bottom of the storage frame is provided with several spaced positioning columns, the shape of which matches the primary spring, and one end of the primary spring can be sleeved on the positioning column. By transferring the storage frame, new primary springs can be transferred to the bogie, and existing primary springs can be transferred to a location away from the bogie without manual handling, reducing labor intensity. At the same time, the centralized transfer of primary springs can also improve the maintenance efficiency of the bogie. The positioning column sleeved on the positioning column facilitates placement and retrieval, and the positioning column can also effectively limit the primary springs during the transfer process, preventing the primary springs from colliding and causing surface damage due to shaking.

[0005] The existing technology has the following drawbacks: Because some processes in the production of suspension springs are highly dangerous, such as heat treatment, these processes are often located in different areas or even different workshops than the relatively safer processes. As a result, during the spring processing, the springs often need to be stacked in a container and transported over long distances using forklifts. However, since the suspension springs have not yet undergone heat treatment, their strength, flexibility, and stability are relatively poor. The suspension springs in the container are squeezed against each other, which may cause deformation and damage. Furthermore, when the spring pitch is large, the springs that are pushed together may become entangled, making them difficult to remove from the container or separate. Summary of the Invention

[0006] In view of the problem of spring deformation due to pushing in the existing technology, a transportation device for suspension spring production and processing is proposed.

[0007] This application provides a transport device for the production and processing of suspension springs, the purpose of which is to: place the springs stably and keep them intact.

[0008] The technical solution of the present invention is: a transportation device for suspension spring production and processing, used to accommodate transport springs, including a tray, a holding frame disposed on the top of the tray, and a placement rack disposed inside the holding frame, with an outer opening on the side of the holding frame; The placement rack specifically includes an outer frame arranged in a linear array within the container, crossbeams arranged in a linear array on the inner side of the outer frame, inner openings arranged in a linear array on the side of the outer frame, and partition components arranged within the crossbeams. The separation component specifically includes a mounting slot arranged in a linear array on the top of the crossbeam, two bearing seats disposed inside the mounting slot, a rotating shaft disposed between the two bearing seats, a partition and a limiting component disposed outside the rotating shaft, and an unloading blocking component and a loading blocking component disposed inside the mounting slot. Two limiting components are provided, respectively distributed on both sides of the partition. The unloading blocking component and the loading blocking component are located on both sides of the partition and correspond to the limiting components. The partition extends vertically out of the mounting groove.

[0009] Furthermore, the unloading blocking component specifically includes an unloading fixing block disposed inside the mounting slot, an unloading sliding groove disposed on the side of the unloading fixing block near the limiting component, an unloading spring and an unloading slider disposed inside the unloading sliding groove, and an unloading connecting groove formed between the mounting slots. One end of the unloading slider extends into the unloading sliding groove, reaching below the limiting component. The unloading connecting groove passes through the unloading fixing block and communicates with the unloading sliding groove. The unloading connecting groove extends into the crossbeam in the inward direction. Two sets of traction ropes are installed inside the unloading connecting groove. One set of traction ropes is connected to the limiting component at one end and to the unloading slider at the other end. The other set of traction ropes is connected to the unloading slider at one end and extends into the crossbeam in the inward direction at the other end.

[0010] Furthermore, the loading barrier component specifically includes a loading fixing block disposed inside the mounting groove, a loading sliding groove disposed on the side of the loading fixing block near the limiting component, a loading spring component and a loading slider disposed inside the loading sliding groove, and a loading connecting groove opened between the mounting grooves. One end of the loading slider extends into a loading sliding groove, and the loading connecting groove passes through the loading fixing block and communicates with the loading sliding groove. A set of traction ropes II is provided inside the unloading connecting groove. One end of the traction ropes II is connected to the limiting component, and the other end is connected to the loading slider.

[0011] Furthermore, the limiting component specifically includes a limiting platform disposed on the outside of the rotating shaft, a fixing hole disposed on the side of the limiting platform, and a fixing bolt disposed on the inside of the fixing hole.

[0012] Furthermore, a suspension beam is provided on the inner side of the outer frame, and the suspension beam is located above the crossbeam. Furthermore, the upper opening of the mounting groove is covered with a cover plate, and the top of the cover plate has an outlet corresponding to the partition.

[0013] Furthermore, a sealing assembly is provided on the outer side of the tray. The sealing assembly specifically includes a mounting base disposed at the outer opening, a sealing plate disposed inside the mounting base, and a handle disposed outside the sealing plate.

[0014] Furthermore, the sealing assembly also includes a locking assembly disposed on the side of the mounting base away from the container frame. The locking assembly specifically includes a fixing platform disposed on the side of the mounting base away from the container frame, a storage hole opened through the top of the fixing platform, an extension spring and a locking bolt disposed inside the storage hole, a top cover disposed at the opening above the storage hole, and a locking hole opened on the top of the sealing plate. The locking bolt extends downward through the receiving hole and into the locking hole on the outside of the lower sealing plate, with the lower end of the locking bolt being hemispherical.

[0015] Furthermore, the sealing assembly also includes an unlocking assembly disposed inside the sealing plate. The unlocking assembly specifically includes a rotating groove opened on the side of the sealing plate away from the container frame, a rotating disk disposed inside the rotating groove, a boss disposed on the outer contour of the rotating disk, a buckle plate disposed at the opening of the rotating groove, and a moving groove opened on the side of the buckle plate. The rotating groove is connected to the locking hole, and the locking bolt passes through the rotating groove. The boss corresponds to the locking bolt and pushes the locking bolt out of the rotating groove. The shortest distance from the inner contour of the rotating groove to the outer contour of the sealing plate is less than the radius of the lower hemisphere of the locking bolt. The handle is fixed to the surface of the rotating disk and extends out from the moving groove.

[0016] Furthermore, the tray specifically includes a frame disposed at the bottom of the container, and a lifting opening and a raising opening opened on the side of the frame; The lifting port penetrates the frame, and the penetration path is perpendicular to the central axis of the inner opening. There are two lifting ports, which are symmetrically distributed on both sides of the frame. The connecting line of the two lifting ports is parallel to the central axis of the inner opening.

[0017] The beneficial effects of this invention are: 1. By setting up placement racks, independent placement spaces are formed within the container frame. Springs are placed in these spaces, making full use of the space within the container frame, ensuring the single transport capacity of the equipment, avoiding reduced transport efficiency, preventing springs from piling up and being squeezed, avoiding spring deformation and damage, and preventing springs from getting tangled together, thus ensuring the integrity of the springs and facilitating the loading and unloading of springs.

[0018] 2. By setting up placement racks, independent placement spaces are formed within the container frame. Springs are placed in these spaces, making full use of the space within the container frame, ensuring the single transport capacity of the equipment, avoiding reduced transport efficiency, preventing springs from piling up and being squeezed, avoiding spring deformation and damage, and preventing springs from getting tangled together, thus ensuring the integrity of the springs and facilitating the loading and unloading of springs.

[0019] 3. By setting up unloading and loading barrier components, when loading springs, the springs push against the innermost partition, causing the partition to deflect and extend the loading slider in the adjacent mounting slot below the mounting base, limiting the deflection angle of the partition. This prevents subsequently added springs from contacting previously added springs. When unloading springs, pulling the traction rope causes the unloading slider to leave the limit assembly, unlocking the partition, and the springs can be removed sequentially. This facilitates the loading and unloading process of springs, ensuring safe transportation while reducing loading and unloading steps.

[0020] 4. By setting up a lifting port, when loading springs, insert the foot-operated jack into the lifting port near the outer opening. One end of the frame is lifted, and the container frame and crossbeam tilt. This causes the springs placed on the crossbeam to slide along the crossbeam, facilitating the loading process. When unloading springs, insert the foot-operated jack into the lifting port away from the outer opening. One end of the frame is lifted, and the container frame and crossbeam tilt, causing the springs on the crossbeam to slide towards the outer opening, facilitating the unloading process. 5. By setting a sealing plate, the outer opening can be sealed to prevent the spring from accidentally sliding out during transportation, thus further ensuring the safety of the spring during transportation. At the same time, by connecting the first traction rope to the sealing plate, the first traction rope will be pulled when the sealing plate is opened, which further facilitates the unloading process of the spring.

[0021] 6. By setting a sealing component, when the sealing plate is closed, the locking bolt is inserted into the locking hole, which restricts the sealing plate to the opening of the outer opening, ensuring the stability of the closed-loop state of the sealing plate. When the sealing plate needs to be opened, hold the handle and turn the rotating disk. The boss pushes the locking bolt to unlock the sealing plate. This makes it easy to open the sealing plate and can be operated with one hand. Attached Figure Description

Detailed implementation manners

[0024] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the drawings in the specification.

[0025] Example 1, referring to Figures 1-14 , which is the first embodiment of the present invention, provides a transportation device for the production and processing of suspension springs, used to accommodate and transport springs, including a tray 1, a loading frame 2 arranged on the top of the tray 1, a placing rack 3 arranged in the loading frame 2, and an outer port 21 opened on the side of the loading frame 2.

[0026] The placing rack 3 specifically includes outer frames 31 arranged in a linear array in the loading frame 2, cross beams 32 arranged in a linear array inside the outer frames 31, inner ports 33 opened in a linear array on the sides of the outer frames 31, and suspension beams 34 arranged inside the outer frames 31, which is convenient to pull the placing rack 3 out of the loading frame 2 from above, and a partition component 4 arranged in the cross beams 32.

[0027] Specifically, the loading frame 2 is assembled from five plates in five directions of front, back, left, right, and bottom. The tray 1 and the loading frame 2 are fixed by bolts. The outer ports 21 are distributed in a rectangular array. The placing racks 3 are distributed in a linear array in the loading frame 2, and adjacent placing racks 3 are mutually adhered. The outer frames 31 are in a "C" shape. The cross beams 32 and the suspension beams 34 are both fixed in the outer frames 31 by bolts. The suspension beams 34 are located above the cross beams 32, which is convenient for the overall lifting and installation of the placing rack 3. The inner ports 33 are correspondingly arranged with the outer ports 21, and the cross beams 32 are correspondingly arranged with the inner ports 33. The springs are placed above the cross beams 32.

[0028] By setting up the placement rack 3, independent placement spaces are formed within the container frame 2. Springs are placed in these spaces, making full use of the space within the container frame 2. This ensures the single transport capacity of the equipment, avoids reduced transport efficiency, and also prevents springs from piling up and being squeezed, deformed or damaged, and from getting tangled together, thus ensuring the integrity of the springs and facilitating their loading and unloading.

[0029] The partition component 4 specifically includes a mounting groove 41 arranged in a linear array on the top of the crossbeam 32, two bearing seats 42 disposed inside the mounting groove 41, a rotating shaft 43 disposed between the two bearing seats 42, a partition 44 and a limiting component 45 disposed outside the rotating shaft 43, an unloading blocking component 46 and a loading blocking component 47 disposed inside the mounting groove 41, and a cover plate 48 disposed at the opening above the mounting groove 41, with an outlet corresponding to the partition 44 on the top of the cover plate 48.

[0030] Specifically, the mounting groove 41 is divided into upper and lower steps. The cover plate 48 covers the upper step of the mounting groove 41 and is fixed with bolts. The inner wall of the upper step of the mounting groove 41 has two assembly grooves corresponding to the bearing seat 42 and two locking grooves corresponding to the unloading blocking component 46 and the loading blocking component 47. The bearing seat 42, the limiting component 45, the unloading blocking component 46 and the loading blocking component 47 are all located in the lower step of the mounting groove 41. The bearing seat 42 is engaged in the assembly groove. The partition plate 44 extends vertically from the outlet of the mounting groove 41 and separates the springs. The rotating shaft 43 is rotatably connected to the bearing seat 42, and a torsion spring is provided at the connection between the two to keep the partition 44 vertical. The inner opening 33 is fixedly connected to the suspension beam 34. Two limiting components 45 are provided and distributed on both sides of the partition 44. The unloading blocking component 46 and the loading blocking component 47 are located on both sides of the partition 44, diagonally distributed, and correspond to the limiting components 45. The top of the unloading blocking component 46 and the loading blocking component 47 are fixedly connected to the side plates, which are snapped into the slots and fixed by bolts. The outer side of the partition 44 is wrapped with a rubber sleeve.

[0031] By setting up the separator component 4, the springs on the same crossbeam 32 are separated by the partition plate 44. This can prevent the springs on the same crossbeam 32 from being squeezed and collided when the transport equipment passes through uphill or downhill or bumpy sections during transportation, thus further protecting the springs.

[0032] The unloading barrier component 46 specifically includes an unloading fixing block 461 disposed inside the mounting groove 41, an unloading sliding groove 462 disposed on the side of the unloading fixing block 461 near the limiting component 45, an unloading spring component 463 and an unloading slider 464 disposed inside the unloading sliding groove 462, and an unloading connecting groove 465 opened between the mounting grooves 41.

[0033] Specifically, the unloading slider 464 is slidably installed in the unloading sliding groove 462. One end of the unloading slider 464 extends out of the unloading sliding groove 462 and reaches below the limiting component 45, preventing the partition 44 from deflecting outward in the direction of the outer opening 21. The unloading connecting groove 465 passes through the unloading fixing block 461 and communicates with the unloading sliding groove 462. The unloading connecting groove 465 extends into the inner opening 33 through the crossbeam 32. Two sets of traction ropes are provided inside the unloading connecting groove 465. One set of traction ropes has multiple ropes. One end of this traction rope is connected to the limiting component 45, and the other end is connected to the unloading slider 464. The other set of traction ropes has one rope. One end of this traction rope is connected to the unloading slider 464, and the other end extends into the inner opening 33 through the crossbeam 32.

[0034] The loading barrier component 47 specifically includes a loading fixing block 471 disposed inside the mounting groove 41, a loading sliding groove 472 disposed on the side of the loading fixing block 471 near the limiting component 45, a loading spring component 473 and a loading slider 474 disposed inside the loading sliding groove 472, and a loading connecting groove 475 opened between the mounting grooves 41.

[0035] Specifically, the loading slider 474 is slidably installed in the loading sliding groove 472. One end of the loading slider 474 extends out of the loading sliding groove 472. The height of the top surface of the loading slider 474 is lower than the height of the bottom surface of the limiting component 45, so that there is a certain deflection buffer space between the two. The loading spring 473 is in a compressed state. The loading connecting groove 475 passes through the loading fixing block 471 and communicates with the loading sliding groove 472. A set of traction ropes II is provided inside the unloading connecting groove 465. One end of the traction ropes II is connected to the limiting component 45, and the other end is connected to the loading slider 474.

[0036] By setting up unloading barrier component 46 and loading barrier component 47, when loading springs, the springs push the innermost partition 44, causing the partition 44 to deflect so that the loading slider 474 in the adjacent mounting slot 41 extends below the mounting base 51, limiting the deflection angle of the partition 44. This prevents subsequently added springs from contacting previously added springs. When unloading springs, pulling the traction rope causes the unloading slider 464 to leave the limiting component 45, unlocking the partition 44, and allowing the springs to be removed sequentially. This facilitates the loading and unloading process of springs, ensuring safe transportation while reducing loading and unloading operation steps.

[0037] Specifically, the limiting component 45 includes a limiting platform 451 disposed on the outside of the rotating shaft 43, a fixing hole 452 disposed on the side of the limiting platform 451, and a fixing bolt 453 disposed on the inside of the fixing hole 452.

[0038] The limiting platform 451 is sleeved on the outside of the rotating shaft 43 and fixed with bolts. The limiting platform 451 is trapezoidal. The fixing hole 452 on the surface of the limiting platform 451 corresponding to the unloading blocking component 46 is located away from the outer opening 21. The fixing hole 452 on the surface of the limiting platform 451 corresponding to the loading blocking component 47 is located close to the outer opening 21. The first traction rope and the second traction rope are both wrapped around the outside of their respective fixing bolts 453. The fixing bolts 453 are threaded into the fixing holes 452, which facilitates the connection of the first traction rope and the second traction rope.

[0039] The tray 1 specifically includes a frame 11 located at the bottom of the container frame 2, a lifting opening 12 and a raising opening 13 on the side of the frame 11.

[0040] Specifically, the frame 11 is made of wood or plastic. The lifting port 12 passes through the frame 11, and the path of the passage is perpendicular to the central axis of the inner port 33. When in use, the two forks of the forklift are inserted into the frame 11 to lift the frame 11 and transport the container 2 and the springs inside the container 2. There are two lifting ports 13, which are symmetrically distributed on both sides of the frame 11. The connecting line of the two lifting ports 13 is parallel to the central axis of the inner port 33. The lifting ports 13 can be used to install a foot-operated jack. The bottom edge of the frame 11 is designed with rounded corners to facilitate the lifting of one end of the frame 11.

[0041] By setting up the lifting port 13, when loading springs, the foot-operated jack is inserted into the lifting port 13 near the outer opening 21, one end of the frame 11 is lifted, and the holding frame 2 and the crossbeam 32 become tilted. In this way, the spring placed on the crossbeam 32 will slide along the crossbeam 32, which facilitates the loading of the springs. When unloading springs, the foot-operated jack is inserted into the lifting port 13 away from the outer opening 21, one end of the frame 11 is lifted, and the holding frame 2 and the crossbeam 32 become tilted, causing the spring on the crossbeam 32 to slide towards the outer opening 21, which facilitates the unloading of the springs.

[0042] Example 2, refer to Figures 1-4 , Figures 15-22 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a sealing component 5 is provided on the outer side of the tray 1. The sealing component 5 specifically includes a mounting base 51 provided at the opening of the outer opening 21, a sealing plate 52 provided on the inner side of the mounting base 51, a handle 53 provided on the outer side of the sealing plate 52, and a through groove provided on the inner wall of the outer opening 21.

[0043] Mounting base 51 is fixed to container frame 2 by bolts, sealing plate 52 is rotatably connected to mounting base 51, sealing plate 52 covers the opening of outer opening 21, and one end of traction rope passing through crossbeam 32 passes through through groove and is connected to the surface of sealing plate 52.

[0044] By setting the sealing plate 52, the outer opening 21 can be closed, preventing the spring from accidentally sliding out of the outer opening 21 during transportation, thus further ensuring the safety of the spring transportation. At the same time, by connecting the first traction rope to the sealing plate 52, the first traction rope will be pulled when the sealing plate 52 is opened, which further facilitates the unloading process of the spring.

[0045] The sealing assembly 5 also includes a mounting base 51 on the side away from the container frame 2. The locking assembly 54 specifically includes a fixing platform 541 on the side of the mounting base 51 away from the container frame 2, a storage hole 542 through the top of the fixing platform 541, an extension spring 543 and a locking bolt 544 inside the storage hole 542, a top cover 545 at the opening above the storage hole 542, and a locking hole 546 at the top of the sealing plate 52.

[0046] Specifically, the sealing plate 52 has a guide slope corresponding to the locking bolt 544 on the side near the outer opening 21. The fixing platform 541 and the mounting base 51 are integrally formed. The surface of the lower mounting base 51 is not provided with the locking component 54, and the upper mounting base 51 is not provided with the sealing plate 52. The locking bolt 544 slides in the extension spring 543. The top cover 545 is snapped above the storage hole 542. One end of the extension spring 543 is in contact with the locking bolt 544, and the other end is in contact with the top cover 545. The locking bolt 544 passes downward through the storage hole 542 and extends into the locking hole 546 on the outside of the lower sealing plate 52. The lower end of the locking bolt 544 is set as a hemispherical shape.

[0047] The sealing assembly 5 also includes an unlocking assembly 55 disposed inside the sealing plate 52. The unlocking assembly 55 specifically includes a rotating groove 551 opened on the side of the sealing plate 52 away from the container frame 2, a rotating disk 552 disposed inside the rotating groove 551, a boss 553 disposed on the outer contour of the rotating disk 552, a buckle 554 disposed at the opening of the rotating groove 551, and a moving groove 555 opened on the side of the buckle 554.

[0048] Specifically, the rotating groove 551 is connected to the locking hole 546, the locking bolt 544 passes through the rotating groove 551, the rotating disk 552 is rotatably connected to the rotating groove 551, the boss 553 corresponds to the locking bolt 544 and pushes the locking bolt 544 out of the rotating groove 551, the shortest distance from the inner contour of the rotating groove 551 to the outer contour of the sealing plate 52 is less than the radius of the lower hemisphere of the locking bolt 544, and the handle 53 is fixed to the surface of the rotating disk 552 by bolts and extends out from the moving groove 555.

[0049] By setting the sealing component 5, when the sealing plate 52 is closed, the locking bolt 544 is inserted into the locking hole 546, which restricts the sealing plate 52 to the opening of the outer opening 21, ensuring the stability of the closed loop state of the sealing plate 52. When the sealing plate 52 needs to be opened, hold the handle 53 and then rotate the rotating disk 552. The boss 553 pushes the locking bolt 544 to unlock the sealing plate 52. This makes it easy to open the sealing plate 52 and can be operated with one hand.

[0050] The remaining structure is the same as that in Example 1.

[0051] Based on embodiments 1-2, the working principle of the suspension spring production and processing transportation device of the present invention is as follows: During installation, the locking bolt 544 and the extension spring 543 are inserted into the receiving hole 542 from above in sequence. Then, the top cover 545 is installed above the receiving hole 542, and the locking bolt 544 extends out from below the receiving hole 542, thus completing the installation of the locking assembly 54. The buckle plate 554 is attached to the surface of the rotating disk 552, and then the two ends of the handle 53 are passed through the moving groove 555 and attached to the surface of the rotating disk 552, and fixed with bolts. Then, the rotating disk 552 is placed into the rotating groove 551, and the buckle plate 554 is attached to the opening of the rotating groove 551 and fixed with bolts, thus completing the installation of the unlocking assembly 55. The bolt mounting seat 51 is fixed to the opening of the outer opening 21, and then the sealing plate 52 is rotated and installed on the mounting seat 51, thus completing the installation of the sealing assembly 5.

[0052] Take out the first set of two traction ropes. Insert one end of the first traction rope through the unloading connecting groove 465 from the outside of the unloading fixing block 461 into the unloading sliding groove 462. Then pull it out of the unloading sliding groove 462. Sleeve the unloading spring 463 on the outside of the first traction rope and insert it into the unloading sliding groove 462. Then connect the first traction rope to the outside of the unloading slider 464 and insert it into the unloading sliding groove 462. The unloading slider 464 is partially left outside the unloading sliding groove 462. This completes the installation of the unloading blocking component 46. Then use a threading tool to thread the other end of the first traction rope through the unloading block 461. The unloading fixing block 461 is placed into the installation slot 41 through the unloading connecting slot 465 and fixed with bolts. When one set of traction ropes passes through the unloading connecting slot 465 into another installation slot 41, it passes through the fixing hole 452 from top to bottom and the fixing bolt 453 is inserted into the fixing hole 452. The same steps are followed to complete the installation of the accessories in multiple installation slots 41. After one end of another set of traction ropes is connected to the unloading slider 464, the other end passes through the unloading connecting slot 465 and leaves the crossbeam 32, and is connected to the surface of the sealing plate 52. In this way, the installation of the unloading blocking sub-component 46 is completed.

[0053] One end of the second traction rope is inserted into the loading sliding groove 472 through the loading connecting groove 475 from the outside of the loading fixing block 471. Then, it is pulled out of the loading sliding groove 472. The loading spring 473 is sleeved on the outside of the second traction rope and inserted into the loading sliding groove 472. The second traction rope is then connected to the outside of the loading slider 474 and inserted into the loading sliding groove 472. The loading slider 474 is left slightly outside the loading sliding groove 472. This completes the installation of the loading barrier component 47. Then, the other end of the second traction rope is passed through the loading connecting groove 475 using a threading tool. The loading fixing block 471 is placed into the mounting groove 41 and fixed with bolts. When the second traction rope passes through the loading connecting groove 475 into another mounting groove 41, it is passed through the fixing hole 452 from bottom to top. The fixing bolt 453 is inserted into the fixing hole 452.

[0054] The limiting platform 451 is fitted onto the outside of the rotating shaft 43 and then fixed with bolts. The two bearing seats 42 are then fitted onto both ends of the rotating shaft 43. The partition plate 44 is then placed vertically into the mounting groove 41, so that the limiting platform 451 on one side is attached to the top of the unloading slider 464, and the limiting platform 451 on the other side is pressed against the loading slider 474. Finally, the cover plate 48 is fastened onto the top of the mounting groove 41.

[0055] Install the crossbeams 32 one by one into the outer frame 31, and finally install the suspension beams 34 into the outer frame 31. This completes the installation of the placement rack 3. Then, lift the placement rack 3 with the suspension beams 34 and insert it into the container frame 2 one by one, so that the inner opening 33 and the outer opening 21 correspond.

[0056] When loading the spring, insert the foot-operated jack into the lifting port 13 near the outer opening 21, activate the foot-operated jack, and lift one end of the frame 11, causing the container frame 2 and the placement rack 3 inside the container frame 2 to tilt. The end of the crossbeam 32 near the inner opening 33 is raised, thus inserting the spring from the outer opening 21 and the inner opening 33 into the placement rack 3. The spring falls above the crossbeam 32 and slides along the crossbeam 32 away from the inner opening 33. When the spring encounters the partition 44, the loading slider 474 is not in contact with the limiting platform 451. The partition 44 is pushed and deflects away from the inner opening 33. When the spring encounters the last partition 44, the partition 44 deflects at a certain angle and is blocked by the inner wall of the outer frame 31. When the partition 44 deflects, the limiting platform 451, which is coaxial with it, also deflects. The connection point between the second and the limiting platform 451 deflects from below towards the inner opening 33, causing the second traction rope to loosen. This weakens the limiting force on the loading slider 474 in the adjacent mounting slot 41. The loading spring 473 pushes the loading slider 474 out of the loading sliding groove 472, causing the loading slider 474 to move below the limiting platform 451. This limits the deflection angle of the limiting platform 451 and the partition 44. When the spring that is subsequently placed comes into contact with the partition 44, the limiting platform 451 is blocked by the loading slider 474 after the partition 44 deflects at a certain angle. The partition 44 cannot be completely rotated, preventing the spring from continuing to move. At the same time, during the deflection of the partition 44, the loading slider 474 in another adjacent mounting slot 41 extends out of the loading sliding groove 472. In the same process, the springs are placed one by one and separated by the partition 44.

[0057] After the outer spring is loaded, hold the handle 53 and push the sealing plate 52 to close the outer opening 21. During this process, the hemispherical part at the bottom of the locking bolt 544 is inserted into the locking hole 546. Then, rotate the rotating disk 552 by the handle 53 to make the boss 553 leave the locking hole 546. The locking bolt 544 extends into the locking hole 546 and enters the rotating groove 551 to lock the sealing plate 52.

[0058] Use the foot-operated jack to restore frame 11 to a horizontal position, remove the foot-operated jack, and use a forklift to move it.

[0059] When the spring is ready to be unloaded after moving it to the designated area, insert the foot-operated jack into the lifting port 13 away from the outer opening 21, and start the foot-operated jack. One end of the frame 11 is lifted, causing the container frame 2 and the placement rack 3 inside the container frame 2 to tilt. The end of the crossbeam 32 away from the inner opening 33 is raised. Hold the handle 53 and then rotate the rotating disk 552. The rotating disk 552 drives the boss 553 to approach the locking hole 546. The boss 553 pushes the locking bolt 544 upward, so that only the lower hemisphere of the locking bolt 544 is in the locking hole 546. At this time, pull the sealing plate 52 with force. The locking bolt 544 squeezes the extension spring 543 and leaves the locking hole 546, thus successfully opening the sealing plate 52.

[0060] After the sealing plate 52 is opened, the spring slides out from the inner opening 33 and the outer opening 21. During the opening of the sealing plate 52, the first traction rope pulls the unloading slider 464, causing it to enter the unloading sliding groove 462 and leave the limiting platform 451. The limiting platform 451 is no longer restricted, and the partition 44 can deflect towards the inner opening 33. The spring side, which was originally blocked by the partition 44, can push the partition 44 away and move closer to the inner opening 33, and then slide out. During the deflection of the partition 44, the first traction rope is pulled by the limiting platform 451. The first traction rope pulls the unloading slider 464 in the adjacent mounting groove 41 into the unloading sliding groove 462, so that the partition 44 here is unlocked. In this way, the springs slide out from the inner opening 33 one by one.
