Abstract
Description
Technical Field
[0001] This application relates to the field of sealed storage technology, and specifically to a track-type sealed storage tunnel. Background Technology
[0002] For sealed storage of logistics equipment, the goods are generally sealed (covered with sealing film or sealant, etc.) and then stored in sealed containers treated with sealing materials.
[0003] However, due to the large size and complex structure of the goods requiring sealing (such as stacker cranes, AGVs, and shuttles), sealing them is difficult. Direct sealing within containers is also challenging, as warehouses themselves become even larger and more complex, making warehouse sealing difficult. Furthermore, moving heavy goods like stacker cranes, AGVs, and shuttles into sealed containers is time-consuming and labor-intensive. Additionally, these items are frequently used, requiring the sealing channels to be opened during operations to allow them to exit the sealed container, and then re-sealing them afterward.
[0004] In the existing technology, items that need to be sealed are placed on a mobile cart and transported to a sealed container. When the mobile cart moves inside the sealed container, it is less constrained because the cart's wheels are casters. Therefore, the mobile cart can move in any direction on the bottom plane of the sealed container, which can easily cause the stored items to collide with the inside of the sealed container, resulting in damage to both the stored items and the sealed container. Utility Model Content
[0005] This application provides a track-type sealed storage tunnel, which aims to solve the problem that existing technologies easily cause storage objects to collide with the inside of the sealed container, resulting in damage to both the storage objects and the sealed container.

[0019] In one embodiment, the second driving component includes a telescopic cylinder and a tension spring; the telescopic cylinder is fixedly mounted on the sealing door; one end of the telescopic cylinder is a telescopic end, and the tension spring is fixedly connected to the other end of the telescopic cylinder; the telescopic end and the tension spring are respectively the first telescopic part and the second telescopic part.
[0020] Specifically, the sealed door is equipped with a base plate, which is slidably connected to the moving rod; the telescopic cylinder is fixedly connected to the base plate.
[0021] In one embodiment, the second driving component further includes: two second pull ropes and two pulley assemblies; one end of each of the two second pull ropes is fixedly connected to the first telescopic part and the second telescopic part respectively, and the other end of each of the two second pull ropes is fixedly connected to the sealing door; the pulley assembly includes two pulley bodies spaced apart from each other; both pulley bodies are rotatably mounted on the fixed plate; the first pull rope and the second pull rope are respectively connected to the two pulley bodies respectively.
[0022] Specifically, the two pulley bodies can move relative to the sealing door. The telescopic cylinder, the first drive motor, and the second drive motor are all electrically connected to an external power source; the sealing door is equipped with a switch button; the telescopic cylinder and the first drive motor are electrically connected to the switch button. The snap-fit block has an inclined surface; a sealing ring is fixedly connected to the end face of the sealing door that abuts against the edge of the opening; when the sealing door is placed over the opening, the sealing ring is sealed by the end face of the sealing door and the edge of the opening, and at the same time, the snap-fit block extends into the sealing box near the opening, and the inner wall of the sealing box is provided with a slot for the snap-fit block to snap into (the inner wall of the slot has an inclined surface that matches the snap-fit block), the snap-fit block abuts against the inner wall surface of the slot, and the wall surface of the snap-fit block abutting against the slot is inclined. After the snap-fit block is inserted into the slot, as the snap-fit block continues to be inserted, the snap-fit block is lifted along the contact surface, causing the sealing door to move along the extension direction of the sealing box.

[0025] The beneficial effects of this application are:
[0026] By setting a track body in the sealing channel inside the sealing box, and by setting a carrier plate on the track body, the carrier plate can move along the track body. The object to be sealed is placed on the carrier plate and sent into the sealing box. Since the carrier plate only moves along the extension direction of the track body, the carrier plate will not bump into the inner wall of the sealing channel, thus avoiding collision damage between the object to be sealed and the sealing channel.
[0027] Meanwhile, some objects to be sealed are also equipped with rollers that are compatible with the track body. The objects to be sealed can be directly opened into the sealing channel. Due to the limiting effect of the track body, the objects to be sealed can only move along the extension direction of the track body. Therefore, the objects to be sealed will not touch the inner wall of the sealing channel and will not cause damage to the sealing channel or the objects to be sealed. Attached Figure Description

[0049] This application proposes improvements and innovations, and presents the following embodiments.
[0050] In some implementations, please refer to Figures 1 to 10 A track-type sealed storage tunnel is provided, comprising:
[0051] The sealed box 1 has a sealed channel 11 inside; the side of the sealed box 1 has an opening 12.
[0052] Support frame 2 is fixedly installed on the outer side of the sealed box 1;
[0053] The track body 3 is laid and fixed at the bottom of the sealed box 1, and the track body 3 extends along the extension direction of the sealed channel 11.
[0054] A sealing door 4 is provided on the opening 12; a drive mechanism 5 for opening or closing the sealing door 4 is fixedly provided on the top of the sealing box 1; a snap-fit mechanism 6 for connecting with the inner wall of the sealing channel 11 is provided on the sealing door 4.
[0055] The sealed box 1 is formed by multiple sealing plates that are connected in sequence to form a cuboid shape with a hollow interior and an opening 12 on one side.
[0056] A carrier plate is provided on the track body 3, and the carrier plate can move along the track body 3. The carrier plate is used to provide a carrier for the object to be sealed.
[0057] By setting a track body 3 in the sealing channel 11 inside the sealing box 1, and by setting a carrier plate on the track body 3, the carrier plate can move along the track body 3. The object to be sealed is placed on the carrier plate and sent into the sealing box 1. Since the carrier plate only moves along the extension direction of the track body 3, the carrier plate will not bump into the inner wall of the sealing channel 11, thus avoiding collision damage between the object to be sealed and the sealing channel 11.
[0058] Meanwhile, some objects to be sealed are also equipped with rollers that are compatible with the track body 3. The objects to be sealed can be directly opened into the sealing channel 11. Due to the limiting effect of the track body 3, the objects to be sealed can only move along the extension direction of the track body 3. Therefore, the objects to be sealed will not touch the inner wall of the sealing channel 11 and will not cause damage to the sealing channel 11 and the objects to be sealed.
[0059] In some embodiments, the drive mechanism 5 includes: a plate 51 having a first limiting groove 511 and a second limiting groove 512, a connecting plate 52 fixedly connected to the sealing door 4, and a first drive member 53; the plate 51 is fixedly connected to the top of the sealing box 1; the first limiting groove 511 extends along the extending direction of the sealing box 1; the second limiting groove 512 is arc-shaped and communicates with the first limiting groove 511; a first limiting block 521 and a second limiting block 522 are fixedly connected to the connecting plate 52; the first limiting block 521 and the second limiting block 522 are spaced apart, the first limiting block 521 can slide in the first limiting groove 511, and the second limiting block 522 can slide in the first limiting groove 511 and the second limiting groove 512; the first drive member 53 is fixedly connected to the top of the sealing box 1, and the first drive member 53 is drively connected to the second limiting block 522.
[0060] With the sealed door 4 closed, i.e., the sealed door 4 covering the opening 12, the first limiting block 521 and the second limiting block 522 are both located within the first limiting groove 511. When the sealed door 4 needs to be opened, the first driving member 53 drives the second limiting block 522 to move, and the connecting plate 52 moves along the extension direction of the first limiting groove 511. When the second limiting block 522 moves to the second limiting groove 512, the second limiting block 522 slides into the second limiting groove 512. As the second limiting block 522 moves within the second limiting groove 512, the connecting plate 52 rotates around the first limiting block 521. The rotation of the connecting plate 52 causes the sealed door 4 to rotate together, ultimately opening the sealed door 4.
[0061] Since the first limiting block 521 and the second limiting block 522 first move within the first limiting groove 511, and the extending direction of the first limiting groove 511 extends in the same direction as the extending direction of the sealing channel 11, the connecting plate 52 moves along the extending direction of the first limiting groove 511, thereby pushing the sealing door 4 to move along the extending direction of the sealing channel 11, thus separating the sealing door 4 from the opening 12. Subsequently, as the second limiting block 522 slides into the second limiting groove 512, the connecting plate 52 rotates around the first limiting block 521. The rotation of the connecting plate 52 causes the sealing door 4 to rotate as well, ultimately opening the sealing door 4. Because the sealing door 4 separates from the opening 12 first, and then the sealing door 4 rotates, the edge of the sealing door 4 will not interfere with the edge of the opening 12, thus affecting the rotation of the sealing door 4. This ensures smooth rotation and is a reasonable design.
[0062] In some embodiments, the arc of the second limiting groove 512 is 90°; one end of the second limiting groove 512 is connected to the first limiting groove 511, and the other end of the second limiting groove 512 is on the same straight line as one end of the second limiting groove 512, and the straight line coincides with the plane where the opening 12 is located. The arc of the second limiting groove 512 is 90°, and the straight line coincides with the plane where the opening 12 is located, thus allowing the sealing door 4 to rotate 90 degrees. This ensures that the object to be sealed can smoothly and reasonably enter and exit the sealing channel 11.
[0063] In some embodiments, the first driving member 53 includes: a first driving motor 531, a crank 532, and a connecting rod 533; the output end of the first driving motor 531 is connected to the crank 532 in a transmission manner; the crank 532 is rotatably connected to the plate 51; the two ends of the connecting rod 533 are respectively rotatably connected to the crank 532 and the second limiting block 522. The first motor drives the crank 532 to rotate, the crank 532 drives the connecting rod 533 to move, and the connecting rod 533 pushes the second limiting block 522 to move. When the second limiting block 522 moves to the connection between the first limiting groove 511 and the second limiting groove 512, the first limiting block 521 abuts against one end of the first limiting groove 511. At this time, as the crank 532 continues to rotate, the crank 532 pushes the second limiting block 522 into the second limiting groove 512, and the second limiting block 522 moves along one end of the second limiting groove 512 to the other end. This structure is simple and reasonably designed.
[0064] Specifically, the output end of the first drive motor 531 and the crank 532 are connected by a worm gear drive. Using a worm gear drive prevents the sealing door 4 from rotating under external forces, thus avoiding damage to the first drive motor 531.
[0065] The plate 51 has an n-shaped cross-section, and the plate 51 and the top of the sealed box 1 enclose a cavity, in which the crank 532, connecting rod 533, and connecting plate 52 are all located. The fact that the crank 532, connecting rod 533, and connecting plate 52 are all located within the cavity of the n-shaped plate 51 effectively protects the safety of the crank 532 and connecting rod 533, while also making the appearance simpler and more aesthetically pleasing.
[0066] In some embodiments, the locking mechanism 6 includes: a plurality of fixed pulleys 61, a plurality of locking blocks 62, a first pull rope 63, and a second driving member 64; the plurality of fixed pulleys 61 are arranged at intervals along the edge of the sealing door 4; the plurality of locking blocks 62 are arranged at intervals along the edge of the sealing door 4, and each locking block 62 is hinged to the sealing door 4; one end of the first pull rope 63 passes through each fixed pulley 61 in sequence and is fixedly connected to the other end, and the first pull rope 63 connects each locking block 62 together; the second driving member 64 is fixedly connected to the sealing door 4; the inner wall of the sealing channel 11 is provided with a slot 13 for the locking blocks 62 to be locked in; the second driving member 64 has a first telescopic part 6401 and a second telescopic part 6402, both used to pull the first pull rope 63 to move.
[0067] The first pull rope 63 is moved by the drive component, which causes the first pull rope 63 to pull the locking block 62 to rotate accordingly. Thus, the locking block 62 is able to be locked into or out of the locking slot 13; finally, the locking of the sealing door 4 and the sealing channel 11 is achieved, which improves the firmness of the connection between the sealing door 4 and the opening 12.
[0068] In some embodiments, the second driving member 64 includes: a movable rod 6403 with a rack and a second drive motor 6404; the movable rod 6403 is slidably connected to the sealing door 4; the output end of the second drive motor 6404 meshes with the rack; the two ends of the movable rod 6403 are a first telescopic part 6401 and a second telescopic part 6402, respectively. The second drive motor 6404 drives the movable rod 6403 to move, one end of the movable rod 6403 pulls the first pull rope 63, and the other end releases the pull of the first pull rope 63, thus realizing the movement of the first pull rope 63. The design of this second driving member 64 is simple and reasonable, ingenious, and effectively drives the movement of the first pull rope 63.
[0069] In some embodiments, the second driving member 64 includes a telescopic cylinder 6405 and a tension spring 6406; the telescopic cylinder 6405 is fixedly mounted on the sealing door 4; one end of the telescopic cylinder 6405 is a telescopic end, and the tension spring 6406 is fixedly connected to the other end of the telescopic cylinder 6405; the telescopic end and the tension spring 6406 are respectively the first telescopic part 6401 and the second telescopic part 6402.
[0070] The telescopic movement of the telescopic cylinder 6405 pulls the first pull rope 63, causing the tension spring 6406 to elastically deform and maintain the tension balance of the first pull rope 63. When the telescopic cylinder 6405 retracts, it pulls the first pull rope 63, causing the locking block 62 to rotate and move into the locking groove 13. When the telescopic cylinder 6405 extends, the tension of the tension spring 6406 pulls the first pull rope 63, causing the locking block 62 to rotate and move out of the locking groove 13. This structure is simple, reasonably designed, and easy to replace and maintain.
[0071] Specifically, the sealing door 4 is provided with a base plate 6407, which is slidably connected to the moving rod 6403; the telescopic cylinder 6405 is fixedly connected to the base plate 6407.
[0072] In some embodiments, the second driving component 64 further includes: two second pull ropes 6408 and two pulley sets 6409; one end of each of the two second pull ropes 6408 is fixedly connected to the first telescopic part 6401 and the second telescopic part 6402 respectively, and the other end of each of the two second pull ropes 6408 is fixedly connected to the sealing door 4; the pulley set 6409 includes two pulley bodies 64091 arranged at intervals; both pulley bodies 64091 are rotatably mounted on the fixed plate 64092; the first pull rope 63 and the second pull rope 6408 are respectively connected to the two pulley bodies 64091. The second pull ropes 6408 and pulley sets 6409 can adjust the driving force of the small second driving component 64 (i.e., the telescopic cylinder 6405) and the second drive motor 6404, adapting to equipment with lower power and reducing production costs. Simultaneously, when using equipment with the same power, the pulling force generated on the first pull rope 63 is greater, increasing the rotational torque of the locking block 62.
[0073] Specifically, the two pulley bodies 64091 can move relative to the sealing door 4. The telescopic cylinder 6405, the first drive motor 531, and the second drive motor 6404 are all electrically connected to an external power source; the sealing door 4 is equipped with a switch button; the telescopic cylinder 6405 and the first drive motor 531 are electrically connected to the switch button. The latching block 62 has an inclined surface; a sealing ring 7 is fixedly connected to the end face of the sealing door 4 that abuts against the edge of the opening 12; when the sealing door 4 covers the opening 12, the sealing ring 7 is sealed by the end face of the sealing door 4 and the edge of the opening 12, and at the same time, the latching block 62 extends into the sealing box 1 near the opening 12, and the inner wall of the sealing box 1 is provided with a slot 13 for the latching block 62 to be latched into (the inner wall of the slot 13 has an inclined surface that matches the latching block), the latching block 62 abuts against the inner wall surface of the slot 13, and the wall surface of the latching block 62 abutting against the slot 13 is inclined. After the snap-fit block 62 is snapped into the slot 13, as the snap-fit block 62 continues to snap into the slot, the snap-fit block 62 is lifted along the contact surface, causing the sealing door 4 to move along the extension direction of the sealing box 1. As a result, the sealing ring 7 is subjected to greater compressive force, which improves the sealing effect between the sealing door 4 and the opening 12.
[0074] In some embodiments, the locking block 62 has a groove 621, and a slider 622 is slidably engaged within the groove 621; the slider 622 is fixedly connected to the first pull rope 63. The groove 621 and the cooperating slider 622 allow the slider 622 to move in the direction of the pull force of the first pull rope 63 when the first pull rope 63 pulls it. Therefore, during the rotation of the locking block 62, the first pull rope 63 will not generate a radial force on the rotation axis of the locking block 62. This improves the service life of both the first pull rope 63 and the locking block 62.
[0075] In some embodiments, the second drive member 64 includes: a first gear 6410, a second gear 6411, a handle 6412, and a chain 6413; both the first gear 6410 and the second gear 6411 are rotatably connected to the sealing door 4; the first gear 6410 meshes with the second gear 6411; the handle 6412 is fixedly connected to the first gear 6410; the chain 6413 is fixedly connected to the first pull rope 63, and the chain 6413 meshes with the second gear 6411; the two ends of the chain 6413 are respectively a first telescopic part 6401 and a second telescopic part 6402.
[0076] By rotating the handle 6412, the first gear 6410 is driven to rotate, and the second gear 6411, which meshes with the first gear 6410, rotates accordingly. The rotation of the second gear 6411 drives the chain 6413 to move, and the movement of the chain 6413 causes the first pull rope 63 to move, ultimately driving the locking block 62. This structure is reasonably designed and can be operated manually by rotating the handle 6412, reducing the need for a drive motor or telescopic cylinder 6405 and lowering production costs.
[0077] Specifically, the size of the first gear 6410 is larger than that of the second gear 6411, and the chain 6413 can move a large distance with a small angle of rotation of the handle 6412. This facilitates rotation.
[0078] Specifically, the sealing door 4 is provided with a limiting hole. When the handle 6412 is rotated to the predetermined position, that is, when the locking block 62 is fully engaged in the slot 13, a limiting pin is inserted into the limiting hole to prevent the handle 6412 from rotating back and causing the locking block 62 to leave the slot 13. This ensures the firmness of the connection.
[0079] The above are merely optional embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of this utility model.
