Description

Technical Field

[0001] This application relates to the technical field of cantilever racks, and in particular to a telescopic support node for cantilever racks. Background Technology

[0002] In warehousing and logistics, there are various usage requirements for the placement of goods. In scenario one, long and narrow goods need to be placed directly on the nodes of the cantilever, and the nodes are used to limit the movement of the goods. In scenario two, large pallets need to be placed on the cantilever, and then the goods are placed on the pallets.

[0003] Reference Figure 1 In scenario two, when using large pallets, the nodes on the cantilever need to be removed to prevent the shelving from squeezing the nodes. At the same time, removing the nodes makes it easier to use the storage space on the cantilever.

[0004] During the exchange process in Scenario 1 and Scenario 2, the nodes need to be repeatedly disassembled and reassembled, resulting in low usability of the nodes. Summary of the Invention

[0005] Therefore, the technical problem to be solved by this application is to improve the usability of nodes in the prior art.

[0006] To address the aforementioned technical problems, this application provides a telescopic support node for cantilever beams, comprising: The cantilever has a telescopic opening on its top surface. The node is used to extend upward through the telescopic opening located above the top surface of the cantilever, and the node is also used to extend downward into the telescopic opening located below the top surface of the cantilever. A guide component, mounted on the cantilever and connected to the node, is used to provide guidance and limit for the vertical movement of the node; The drive component, mounted on the cantilever, is used to drive the node to move vertically.

[0007] By adopting the above technical solution, the node can be raised and lowered in the vertical direction through the driving component, enabling the node to meet the usage requirements of various scenarios, avoiding repeated disassembly and installation of the node, thereby improving the practicality of the node.

[0008] Preferably, it further includes: a support component disposed on the node, the support component including a support block, which extends and supports the node in the vertical direction when the support component is in the activated state; and retracts and facilitates the descent of the node in the vertical direction when the support component is in the deactivated state. An adjustment component is set on a node and is used to adjust the working state of the support component under the influence of the driving component.

[0009] By adopting the above technical solution, the support components can provide effective support for the raised nodes, reduce the load on the drive components, and enable the nodes to be stably set on the cantilever top surface.

[0010] Preferably, the support component further includes a limiting plate, and two limiting plates and two support blocks are provided, with one limiting plate and one support block corresponding to each other; The support block is located below the node, and the two support blocks are symmetrically arranged on both sides of the node. The support block and the node are slidably connected in the horizontal direction. The limiting plate is fixedly connected to the cantilever. When the support block is located below the top surface of the cantilever, the limiting plate is used to abut against and restrict the sliding of the support block.

[0011] Preferably, the adjustment component includes: The adjusting ring is horizontally positioned below the node and rotates around its own axis to connect with the node. There are two first magnets, each corresponding to a support block. The two first magnets are symmetrically arranged on the adjustment ring, and there is an attractive force between the first magnets and the support blocks. There are two second magnets, each corresponding to a support block. The two second magnets are symmetrically arranged on the adjustment ring, and there is a repulsive force between the second magnets and the support blocks.

[0012] By adopting the above technical solution, the first magnet and the second magnet are alternately aligned with the corresponding support blocks by rotating the adjustment ring, thereby achieving the mutual separation and mutual approach of the two support blocks.

[0013] Preferably, the bottom surface of the node has a mounting groove; the driving component includes: The cylinder is mounted on the cantilever and located below the mounting slot. The rack is fixedly connected to the movable end of the cylinder; The rotating shaft is horizontally set and rotatably connected to the node, with one end of the rotating shaft located in the mounting groove and the other end located inside the node; The gear is coaxially sleeved on the rotating shaft and fixedly connected to the rotating shaft. The gear is located in the mounting groove and is used to cooperate with the rack. The first bevel gear is coaxially sleeved on the rotating shaft and fixedly connected to the rotating shaft; the first bevel gear is located inside the node; The second bevel gear is coaxially arranged with the adjusting ring. The second bevel gear is located at the bottom of the node and is fixedly connected to the adjusting ring. The second bevel gear meshes with the first bevel gear.

[0014] Preferably, two guide components are provided, each corresponding to a support block and a limiting plate. Each guide component includes: The guide plate is fixedly connected to the limiting plate. The guide plate is located below the corresponding support block and is used to support the corresponding support block. There are two guide rods. The guide rods are vertically inserted into the corresponding guide plates and are slidably connected to the guide plates in the vertical direction. The top of the guide rod is fixedly connected to the node.

[0015] By adopting the above technical solution, the moving end of the cylinder moves upward, which in turn moves the rack upward, causing the rack to drive the gear to rotate; the gear rotates together with the first bevel gear, the second bevel gear, and the adjusting ring through the rotating shaft, so that the second magnet is directly opposite the support block; When the second magnet and the support block are positioned opposite each other, the end of the cylinder's movable end just touches the node. At this time, the cylinder's movable end continues to move upward, driving the node upward to the top of the cantilever. After the support block disengages from the telescopic port, the support block slides away from the second magnet under the action of the second magnet, and the support block touches the top surface of the cantilever, so that the support block provides effective and stable support for the node. When the node needs to be retracted, the moving end of the cylinder drives the rack to move downward. At this time, due to the support of the support block, the vertical position of the node and the gear is stabilized, which causes the rack to drive the gear to rotate in the opposite direction during the downward movement, thereby resetting the adjusting ring, the first magnet and the second magnet, and realizing the direct alignment of the first magnet and the support block. The support block approaches the adjustment ring under the action of the first magnet. When the distance between the support block and the adjustment ring returns to the preset position, the support block disengages from the top surface of the cantilever, allowing the node to penetrate the telescopic opening downwards by its own weight, making it easy for the tray to be placed directly on the cantilever.

[0016] Preferably, the top surface of the guide plate is provided with a flexible buffer layer.

[0017] In summary, this application includes at least one of the following beneficial technical effects for telescopic support nodes used in cantilever structures: 1. By changing the vertical position of the node through the driving component, the node can adapt to various working scenarios. After the node is raised, the support component can provide effective support for the node, making the support state of the node more stable after being raised. This allows the node to accommodate heavy goods, thereby further enhancing its practicality. Attached Figure Description

[0020] The present application will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present application, but the embodiments are not intended to limit the present application.

[0021] This application discloses a telescopic support node for cantilever beams. (Refer to...) Figures 2 to 9 A telescopic support node for a cantilever includes a cantilever 1, a node 2, a guide assembly 3, and a drive assembly 4. The top surface of the cantilever 1 has a telescopic opening 11. The node 2 is used to extend upward through the telescopic opening 11 above the top surface of the cantilever 1, and the node 2 is also used to extend downward through the telescopic opening 11 below the top surface of the cantilever 1. The guide assembly 3 is disposed on the cantilever 1 and connected to the node 2. The guide assembly 3 is used to provide guidance and limit for the vertical movement of the node 2. The drive assembly 4 is disposed on the cantilever 1 and is used to drive the node 2 to move in the vertical direction.

[0022] In this embodiment, cantilever 1 is an I-beam structure.

[0023] A telescopic support node for a cantilever also includes a support assembly 5 and an adjustment assembly 6. The support assembly 5 includes two support blocks 51 and two limiting plates 52. The support blocks 51 and the limiting plates 52 correspond one-to-one. The support blocks 51 are located below the node 2, and the two support blocks 51 are symmetrically arranged on both sides of the node 2. The support blocks 51 are slidably connected to the node 2 in the horizontal direction. The limiting plates 52 are vertically arranged below the telescopic opening 11, and the two limiting plates 52 are symmetrically arranged on both sides of the telescopic opening 11. The limiting plates 52 are fixedly connected to the cantilever 1. In the initial state, there is a distance between the support blocks 51 and the corresponding limiting plates 52. When the support blocks 51 abut against the limiting plates 52, the support blocks 51 can pass through the telescopic opening 11 under the action of the drive assembly 4.

[0024] It should be noted that the sliding connection structure between the support block 51 and the node 2 is as follows: the bottom of the node 2 has two sliding grooves that correspond one-to-one with the support block 51, and a slider that cannot be disengaged from the sliding groove is slidably installed in the sliding groove; the support block 51 is fixedly connected to the corresponding slider.

[0025] The adjustment component 6 includes an adjustment ring 61, a first magnet 62, and a second magnet 63. The adjustment ring 61 is horizontally positioned directly below node 2 and is rotatably connected to node 2 around its own axis. There are two first magnets 62, each corresponding to a support block 51. The two first magnets 62 are symmetrically arranged on both sides of the adjustment ring 61 and are fixedly embedded in the adjustment ring 61. There is an attractive force between the first magnets 62 and the support blocks 51. There are two second magnets 63, each corresponding to a support block 51. The two second magnets 63 are symmetrically arranged on both sides of the adjustment ring 61 and are fixedly embedded in the adjustment ring 61. There is a repulsive force between the second magnets 63 and the support blocks 51, and the second magnets 63 and the first magnets 62 are located in the same horizontal plane.

[0026] A mounting groove 21 is provided on the bottom surface of node 2; the drive assembly 4 includes a cylinder 41, a rack 42, a rotating shaft 43, a gear 44, a first bevel gear 45, and a second bevel gear 46. The cylinder 41 is vertically positioned below the mounting groove 21, with its fixed end fixedly connected to the cantilever 1, and a preset distance between its movable end and the bottom surface of the mounting groove 21. The rack 42 is vertically positioned and fixedly connected to the movable end of the cylinder 41, with a preset distance between its top end and the bottom surface of the mounting groove 21. The rotating shaft 43 is horizontally positioned and rotatably connected to node 2. One end of shaft 43 is located inside mounting groove 21, and the other end is located inside node 2; gear 44 is coaxially sleeved on shaft 43 and fixedly connected to shaft 43. Gear 44 is located inside mounting groove 21 and is used to cooperate with rack 42; first bevel gear 45 is coaxially sleeved on shaft 43 and fixedly connected to shaft 43. First bevel gear 45 is located inside node 2; second bevel gear 46 is coaxially arranged with adjusting ring 61. Second bevel gear 46 is located at the bottom of node 2 and fixedly connected to adjusting ring 61. Second bevel gear 46 and first bevel gear 45 mesh with each other.

[0027] It should be noted that in the rotational connection structure between the adjusting ring 61 and the node 2, the bottom of the node 2 is provided with a rotational groove, and a sliding ball that cannot be disengaged from the rotational groove is slidably disposed in the rotational groove; the adjusting ring 61 is fixedly connected to the sliding ball.

[0028] Two guide components 3 are provided, each corresponding to a support block 51 and a limiting plate 52. Each guide component 3 includes a guide plate 31 and a guide rod 32. The guide plate 31 is fixedly connected to the limiting plate 52 and is located below the corresponding support block 51, and is used to support the corresponding support block 51. Two guide rods 32 are provided. The guide rods 32 are vertically inserted into the corresponding guide plate 31 and are slidably connected to the guide plate 31 in the vertical direction. The top of the guide rod 32 is fixedly connected to the node 2.

[0029] The top surface of the guide plate 31 is provided with a flexible buffer layer to alleviate the squeezing between the support block 51 and the guide plate 31 when the node 2 descends.

[0030] The implementation principle of this application embodiment is as follows: In the initial state, the top plane of node 2 is flush with the top surface of cantilever 1. When node 2 needs to be raised, the operator controls the movable end of cylinder 41 to move upward. During the upward movement of cylinder 41, it drives rack 42 to move, so that rack 42 moves upward a certain distance and drives gear 44 to rotate, thereby causing adjustment ring 61 to rotate, so that the second magnet 63 is aligned with support block 51. During the rotation of gear 44, the moving end of cylinder 41 and rack 42 are not in contact with node 2 in the vertical direction, so that node 2 maintains its vertical position by its own weight, thereby enabling rack 42 to drive gear 44 to rotate. When the second magnet 63 is directly opposite the support block 51, the end of the movable end of the cylinder 41 is in contact with the node 2. At this time, the movable end of the cylinder 41 continues to move upward and drives the node 2 to move upward to above the cantilever 1. After the support block 51 is disengaged from the telescopic port 11, the support block 51 slides away from the adjusting ring 61 under the action of the second magnet 63, and the support block 51 abuts against the top surface of the cantilever 1, so that the support block 51 provides effective and stable support for the node 2. When node 2 needs to be retracted, the movable end of cylinder 41 drives rack 42 to move downward. At this time, due to the support of support block 51, the vertical position of node 2 and gear 44 is stabilized, which causes rack 42 to drive gear 44 to rotate in the opposite direction during the downward movement, thereby resetting adjustment ring 61, first magnet 62 and second magnet 63, realizing the direct alignment of first magnet 62 and support block 51. Under the action of the first magnet 62, the support block 51 approaches the adjustment ring 61. When the distance between the support block 51 and the adjustment ring 61 returns to the preset position, the support block 51 disengages from the top surface of the cantilever 1, allowing the node 2 to penetrate downward into the telescopic opening 11 by its own weight, so that the tray can be placed directly on the cantilever 1.

[0031] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
