Description

Technical Field

[0001] This invention relates to the field of long-distance transport technology, specifically to a long-distance transport device with automatic lifting function. Background Technology

[0002] The automatic lifting long-distance transfer device is a material handling equipment that combines automation technology, featuring remote control and lifting functions. Through an electric drive system and hydraulic devices, this equipment can achieve rapid lifting, horizontal transfer, and precise positioning of materials. It is suitable for warehousing, logistics, and production line scenarios, improving transportation efficiency and reducing the risks associated with manual operation.

[0003] Chinese patent CN217024099U discloses a long-distance transfer device with automatic lifting function, including a transfer vehicle. The transfer vehicle is cyclically positioned in at least two workshops via a display control station. Lifting mechanisms are installed below the ground level of each of the at least two workshops. A set of detection radars is installed on each of the front and rear sides of the transfer vehicle. The two sets of detection radars are electrically connected to the lifting mechanisms via the display control station, which is located above the ground level of one side of the workshop. This patent allows the transfer vehicle to be cyclically positioned in at least two workshops via the display control station, enabling the transfer vehicle to move more efficiently, smoothly, and quickly between multiple workshops. This improves the production quality and efficiency of polyethylene fiber, simplifies the transfer process, and effectively reduces costs. Furthermore, the accuracy of the detection radars ensures the stability and safety of the transfer vehicle during operation.

[0004] However, current transfer devices have the following problems: Currently, long-distance transfer devices are usually flat trolleys. When it is necessary to transfer cylindrical items, the flat trolleys have difficulty maintaining the stability of the cylindrical items. Therefore, special cylindrical item transfer trolleys are required. However, due to construction requirements, the transfer trolleys need to be changed back and forth, which requires additional time and manual operation. This will reduce the overall efficiency of the transfer system. Especially in large-scale production and logistics, each change may lead to wasted time and process interruption. Therefore, we propose a long-distance transfer device with automatic lifting function. Summary of the Invention

Two threaded sleeves are threadedly connected to the circumferential surfaces of the bidirectional threaded rod with opposite thread directions. The two threaded sleeves are the driving ends of the driving component.

[0008] According to the above technical solution, the support member includes a fixed frame fixed to the top of the connector on the side away from the driving member. A sliding rod is fixedly connected to the inner wall of the fixed frame. Two sliders are slidably connected to the outer wall of the sliding rod.

[0009] According to the above technical solution, the support plate passes through and slides on the bottom of the placement plate.

[0010] According to the above technical solution, a separating device is provided on the side of the connector. The separating device includes a rotating rod. The outer wall of the rotating rod is rotatably mounted on the side of the connector. An L-shaped adjusting block is fixedly connected to the outer wall of the rotating rod.

[0012] According to the above technical solution, an auxiliary device is provided on the side of the push plate. The auxiliary device includes a fixing block, which is fixedly connected to the side of the push plate. Multiple hemispherical blocks are fixedly connected to the side of the fixing block.

[0013] According to the above technical solution, the second hemispherical block is located on the displacement trajectory of the first hemispherical block, the multiple elastic partition plates are respectively located on the displacement trajectory of the multiple L-shaped rods, and the bottom of the placement plate is provided with a long groove for placing the connecting block.

[0014] This invention provides a long-distance transfer device with automatic lifting function. It has the following advantages:

[0015] (1) The present invention uses the cooperation of electric push rod, connector, support frame, drive component, connecting rod, support plate and support component to enable support plate 46 to block cylindrical items, thereby avoiding the difficulty of the flat trolley in maintaining the stability of cylindrical items. Therefore, a special cylindrical item transfer trolley is required. However, due to the construction requirements, the transfer trolley needs to be changed back and forth, which requires additional time and manual operation, reducing the working efficiency of the overall transfer system. Especially in large-scale production and logistics, each change may lead to time waste and process interruption. At the same time, through the cooperation of bidirectional threaded rod, threaded sleeve, connecting rod and support plate, the opposite movement of the two threaded sleeves will drive the support plate to move towards the middle cylindrical item through the connecting rod connected to each of them. Thus, the two support plates can be adjusted according to the different radii of the cylindrical items, thereby improving the adaptability of the two support plates.

[0016] (2) By setting up the separation device, the present invention enables the rotating rod, L-shaped adjusting block, push plate and elastic separation plate to cooperate so that the push plate will push multiple elastic separation plates to move upward along the inner wall of the placement plate during the upward movement of the push plate. This will cause multiple elastic separation plates to separate multiple small cylindrical items for transfer, which can avoid collision or friction of small cylindrical items during transportation, thereby reducing the risk of damage to the items. At the same time, by cooperating with the push plate and elastic separation plates, the vertical push plate will enter the slots of multiple elastic separation plates, thereby ensuring that the push plate will not push multiple elastic separation plates to move.

[0017] (3) The present invention, through the setting of auxiliary devices, enables the fixed block, hemispherical block one, L-shaped block, connecting block, hemispherical block two, spring, and L-shaped rod to cooperate, so that the spring will drive the connecting block and L-shaped rod to reset through its own elastic force. The reset of the L-shaped rod will reset the elastic partition plate. This process is repeated, so that the elastic partition plate will sway back and forth slightly when separating multiple small cylindrical items, thereby further increasing the efficiency of the elastic partition plate in separating multiple small cylindrical items. At the same time, through the cooperation of the fixed block, hemispherical block one, L-shaped block, connecting block, hemispherical block two, spring, L-shaped rod rotating rod, L-shaped adjusting block, push plate, and elastic partition plate, the staff can adjust according to the items to be transferred, thereby increasing the work efficiency of the staff.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Please see Figures 1-7 One embodiment of the present invention is as follows: a long-distance transfer device with automatic lifting function, comprising a transfer vehicle body 1, a lifting component 2 disposed on the top of the transfer vehicle body 1, a placement plate 3 fixedly connected to the top of the lifting component 2, a switching device 4 disposed at the bottom of the placement plate 3, the switching device 4 comprising two electric push rods 41, the tops of the two electric push rods 41 being fixedly connected to the bottom of the placement plate 3, the bottom of the telescopic ends of the two electric push rods 41 being fixedly connected to connectors 42, the top of one side of the two connectors 42 being fixedly connected to the same support frame 43, a driving component 44 disposed on the inner wall of the support frame 43, the two driving ends of the driving component 44 being fixedly connected to connecting rods 45, the ends of the two connecting rods 45 away from the driving component 44 being fixedly connected to the same support plate 46, and the top of the side of the connector 42 away from the driving component 44 being provided with a for The support member 47 supports the support plate 46. The support member 47 includes a fixed frame 4701 fixed to the top of the connector 42 on the side away from the drive member 44. A slide rod 4702 is fixedly connected to the inner wall of the fixed frame 4701. Two sliders 4703 are slidably connected to the outer wall of the slide rod 4702. Support rods 4704 are fixedly connected to the sides of the two sliders 4703. The two support rods 4704 are fixedly connected to the sides of the two support plates 46. The support plate 46 passes through and slides on the bottom of the placement plate 3. With the above structure, the support plate 46 can block cylindrical items, thereby avoiding the need to change the transfer cart back and forth, which requires additional time and manual operation. This would reduce the working efficiency of the overall transfer system, especially in large-scale production and logistics, where each change may lead to wasted time and process interruption.

[0030] The driving component 44 includes a bidirectional threaded rod 4401, which passes through and rotates on the inner wall of the support frame 43. The bidirectional threaded rod 4401 is driven by a motor, which is fixedly connected to the side of the support frame 43. Two threaded sleeves 4402 are threadedly connected to the circumferential surfaces of the bidirectional threaded rod 4401 with opposite thread directions. The two threaded sleeves 4402 are the driving ends of the driving component 44. With the above structure, the opposite movement of the two threaded sleeves 4402 will drive the support plate 46 to move towards the central cylindrical object through the connecting rod 45 connected to each of them. This allows the two support plates 46 to be adjusted according to the different radii of the cylindrical object, thereby improving the adaptability of the two support plates 46.

[0031] A separating device 5 is provided on the side of the connector 42. The separating device 5 includes a rotating rod 51. The outer wall of the rotating rod 51 is through and rotatably mounted on the side of the connector 42. An L-shaped adjusting block 52 is fixedly connected to the outer wall of the rotating rod 51. A push plate 53 is fixedly connected to the outer wall of the rotating rod 51. Multiple elastic separating plates 54 for being pushed by the push plate 53 are through and slidable on the bottom of the placement plate 3. The sides of the connector 42 and the L-shaped adjusting block 52 are provided with slots for connection by pins. The bottom of the multiple elastic separating plates 54 is provided with slots for placing the push plate 53. With the above structure, when the push plate 53 moves upward, it will push the multiple elastic separating plates 54 to move upward along the inner wall of the placement plate 3. This will cause the multiple elastic separating plates 54 to separate multiple small cylindrical items for transfer, which can avoid collision or friction of small cylindrical items during transportation, thereby reducing the risk of damage to the items.

[0032] In use, the items to be transported are placed on the placement plate 3, and then the lifting component 2 is adjusted according to the required height. The items are then transported to the designated location by the main body 1 of the transport vehicle. Since current long-distance transport devices are usually flat trolleys, when transporting cylindrical items, the flat trolley is difficult to keep the cylindrical items stable. Therefore, a special cylindrical item transport trolley is required. However, due to construction requirements, the transport trolley needs to be changed back and forth, which requires additional time and manual operation. Therefore, the operator retracts the electric push rod 41 through the telescopic end of the external controller. At this time, the telescopic end of the electric push rod 41 will drive the connecting part 42 to move towards the placement plate 3. The movement of the connecting part 42 will simultaneously drive the support frame 43 and the fixed frame 4701 to move upward. The upward movement of the support frame 43 and the fixed frame 4701 will respectively drive the bidirectional threaded rod 4401, the threaded sleeve 4402, the connecting rod 45, the sliding rod 4702, the slider 4703, and the support rod 4704 to move upward. The movement causes the support plate 46 to move upward along the placement plate 3, thus blocking the cylindrical object and preventing the flat trolley from being unable to maintain the stability of the cylindrical object. Therefore, a special cylindrical object transfer trolley is required. However, due to construction requirements, the transfer trolley needs to be changed back and forth, which requires additional time and manual operation, reducing the overall efficiency of the transfer system. Especially in large-scale production and logistics, each change may lead to wasted time and process interruption. When the radius of the cylindrical object is different, the operator can start the motor corresponding to the bidirectional threaded rod 4401, which will cause the bidirectional threaded rod 4401 to rotate. The rotation of the bidirectional threaded rod 4401 will cause the two threaded sleeves 4402 to move towards each other. The opposite movement of the two threaded sleeves 4402 will drive the support plate 46 towards the central cylindrical object through the connecting rod 45 connected to each of them. Thus, the two support plates 46 can be adjusted according to the different radii of the cylindrical objects, thereby improving the adaptability of the two support plates 46.

[0033] When multiple small cylindrical items are placed on the placement plate 3, the operator can remove the pin securing the L-shaped adjusting block 52 and the connector 42. Then, the operator rotates the L-shaped adjusting block 52 ninety degrees. This rotation causes the rotating rod 51 to rotate, which in turn rotates the push plate 53, turning it from its original vertical position to a horizontal position. The pin is then used to secure the rotated L-shaped adjusting block 52 to the connector 42. When the connector 42 moves upward, it causes the rotating rod 51 to move upward, which in turn... As the pusher plate 53 moves upward, it pushes multiple elastic partition plates 54 upward along the inner wall of the placement plate 3. This allows the multiple elastic partition plates 54 to separate multiple small cylindrical items for transport, avoiding collisions or friction between the small cylindrical items during transportation and reducing the risk of damage. When the multiple small cylindrical items are no longer being transported, the above structure is reset. At this time, the upright pusher plate 53 will enter the slots of the multiple elastic partition plates 54, thus ensuring that the pusher plate 53 will not push the multiple elastic partition plates 54 to move.

[0034] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, an auxiliary device 6 is provided on the side of the push plate 53. The auxiliary device 6 includes a fixing block 61, which is fixedly connected to the side of the push plate 53. A plurality of hemispherical blocks 62 are fixedly connected to the side of the fixing block 61. An L-shaped block 63 is fixedly connected to the bottom of the placement plate 3. An elastic telescopic block 641 is slidably connected to the bottom of the inner wall of the L-shaped block 63. A connecting block 64 is fixedly connected to the top of the telescopic end of the elastic telescopic block 641. A hemispherical block 65 is fixedly connected to the lower side of the elastic telescopic block 641. The elastic telescopic block 641 and the L-shaped block 63... A spring 66 is provided between the components. Multiple L-shaped rods 67 are fixedly connected to the top of the connecting block 64. The sides of the multiple L-shaped rods 67 away from the connecting block 64 are fixedly connected to the lower side of the elastic partition plate 54. The second hemispherical block 65 is located on the displacement trajectory of the multiple first hemispherical blocks 62. The multiple elastic partition plates 54 are respectively located on the displacement trajectory of the multiple L-shaped rods 67. The bottom of the placement plate 3 is provided with a long groove for placing the connecting block 64. With the above structure, the reset of the L-shaped rods 67 will knock on the elastic partition plate 54, thereby further increasing the efficiency of the elastic partition plate 54 in separating multiple small cylindrical items.

[0035] In use, when the push plate 53 is turned horizontally, it will cause the fixing block 61 to stand upright. The upright position of the fixing block 61 will cause the first hemispherical block 62 to stand upright as well. When the push plate 53 moves upward, it will also cause the fixing block 61 to move. The movement of the fixing block 61 will cause the first hemispherical block 62 to move, and this movement will cause the second hemispherical block 65 to push the elastic telescopic block 641 onto the L-shaped block 63, compressing the spring 66. The movement of the elastic telescopic block 641 will then... The connecting block 64 moves, and the movement of the connecting block 64 will cause the elastic partition plate 54 to deform through the L-shaped rod 67. When the movement of the first hemispherical block 62 does not resist the second hemispherical block 65, the spring 66 will drive the connecting block 64 and the L-shaped rod 67 to reset through its own elastic force. The reset of the L-shaped rod 67 will reset the elastic partition plate 54. This process is repeated, so that the elastic partition plate 54 will sway back and forth slightly when separating multiple small cylindrical items, thereby further increasing the efficiency of the elastic partition plate 54 in separating multiple small cylindrical items.

[0036] It should be noted that when all hemispherical blocks 62 are no longer in contact with hemispherical blocks 65, the pusher plate 53 has already pushed the elastic partition plate 54 to move half the distance. Therefore, the auxiliary device 6 will not be unable to move when the elastic partition plate 54 separates multiple small cylindrical objects.

[0037] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
