Description
Technical Field
[0001] This utility model relates to the field of shelving technology, specifically a high-level telescopic cantilever shelving. Background Technology
[0002] With the acceleration of urbanization, warehouse rents and land costs continue to rise, and e-commerce and logistics centers are demanding increasingly efficient use of warehousing space. High-bay racking, typically over 8 meters high, maximizes the use of vertical space. Combined with telescopic functionality, it avoids interference with adjacent storage locations when storing and retrieving goods, and can be used in conjunction with overhead cranes, AGV robots, and other equipment for efficient operation, meeting the core needs of modern warehousing for high density and high efficiency.
[0003] Existing devices mainly employ single-cantilever telescopic racks. Current technologies are largely similar to a telescopic cantilever rack, as illustrated in CN221044562U. The structure includes a main frame slide rail, a lifting block slidably connected to the inner wall of the main frame slide rail, a first rotating block rotatably connected to the inner wall of the lifting block, a first lead screw mounted on the inner wall of the main frame slide rail, a rack positioned in front of the lifting block, reinforcing ribs on the lower surface of the rack, a first locking block at one end of a second bevel gear, a rotating rod rotatably connected to the inner wall of the reinforcing rib, and a telescopic extension rod slidably connected to the inner wall of the rack. This device facilitates height adjustment, expansion of the rack box to both sides, and adjustment of the extension length of the telescopic extension rod. However, there are still areas for improvement.
[0004] Existing systems primarily control the extension and retraction of individual cantilever arms via a screw mechanism. This makes it difficult to synchronously control the displacement of a pair of extension arms, leading to some racks being prone to tipping over due to a shift in the center of gravity of the cantilever arms on both sides. Furthermore, some systems utilize integrated cantilever racks to support pallets and goods, making it difficult to assemble the appropriate number of cantilever arms according to the needs of high-level racking. This results in limitations in supporting multiple layers of goods, reducing the system's efficiency and practicality. Therefore, to address these issues, a high-level telescopic cantilever rack is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a high-level telescopic cantilever rack to address the problems mentioned in the background section. Existing devices primarily control the extension and retraction of a single cantilever using a screw structure, making it difficult to synchronously control the displacement of a pair of extension arms. This can lead to some racks easily tipping over due to the shift in the center of gravity of the cantilever arms on both sides. Furthermore, some devices primarily use integrated cantilever racks to support pallets and goods, making it difficult to install the appropriate number of cantilever arms according to the needs of high-level racks, thus hindering the ability to support multiple layers of goods.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-position telescopic cantilever rack, including a base, a transmission box above the base, fixed arms on the left and right sides of the transmission box, an extension arm slidably connected to the outer side of the fixed arms, an adjustment mechanism inside the transmission box, a pair of uprights fixedly mounted on the bottom rear side of the transmission box, a mounting mechanism below the outer wall of the pair of uprights, a sleeve fitted at the bottom end of the uprights, and the bottom of the sleeve fixedly mounted on the top rear side of the base and the transmission box.
[0007] Preferably, the adjusting mechanism includes a symmetrical screw, which is inserted and installed inside the transmission box. Limiting rings are fixedly sleeved on both sides of the outer wall of the symmetrical screw inside the transmission box, and a second bevel gear is fixedly sleeved on the middle of the outer wall of the symmetrical screw.
[0008] Preferably, the rear side of the second bevel gear is meshed with the first bevel gear, the rear middle of the first bevel gear is fixedly connected to a drive shaft, and the rear end of the drive shaft passes through the limiting hole of the transmission box and is fixedly connected to a first twist cover.
[0009] Preferably, the outer walls of the symmetrical screw are fitted with push screw cylinders on both sides inside the fixed arm, and the outer ends of the push screw cylinders are fixedly connected to the inner side of the extension arm.
[0010] Preferably, the mounting mechanism includes a limiting seat, which is sleeved on the outer wall of a pair of uprights. A plug-in bolt is inserted into the front inner wall of the limiting seat, and a second twist cap is fixedly connected to the top of the plug-in bolt.
[0011] Preferably, a fixing screw is threaded on the lower part of the outer wall of the plug bolt, and the bottom of the fixing screw is fixedly installed on the top front side of the base and the transmission box.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model allows for symmetrical adjustment of the extension arms via an adjustment mechanism, enabling some devices to synchronously control the displacement of a pair of extension arms. This effectively prevents the center of gravity of the cantilever arms on both sides of the shelf from shifting and tipping over, thus improving the stability and practicality of the device.
[0013] 2. This utility model uses an assembly mechanism to sequentially add telescopic cantilever arms above the base, allowing some devices to be equipped with a corresponding number of cantilever arms according to the needs of high-rise shelves, facilitating the carrying of multiple layers of goods and improving the applicability and practicality of the device.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1-5 One embodiment provided by this utility model: A high-level telescopic cantilever rack includes a base 11, a transmission box 12 above the base 11, fixed arms 13 on the left and right sides of the transmission box 12, an extension arm 14 slidably connected to the outer side of the fixed arms 13, an adjustment mechanism 2 inside the transmission box 12, a pair of uprights 15 fixedly mounted on the bottom rear side of the transmission box 12, a mounting mechanism 3 below the outer wall of the pair of uprights 15, a plug 16 sleeved at the bottom end of the uprights 15, and the bottom of the plug 16 fixedly mounted on the top rear side of the base 11 and the transmission box 12.
[0018] The adjusting mechanism 2 includes symmetrical screws 21, which are inserted and installed inside the transmission box 12. Limiting rings 22 are fixedly sleeved on both sides of the outer wall of the symmetrical screws 21 inside the transmission box 12. A second bevel gear 23 is fixedly sleeved on the middle of the outer wall of the symmetrical screws 21. This design allows the second bevel gear 23 to drive the symmetrical screws 21 to rotate within the transmission box 12.
[0019] The rear side of the second bevel gear 23 is meshed with the first bevel gear 24. The rear middle of the first bevel gear 24 is fixedly connected to the drive shaft 25. The rear end of the drive shaft 25 passes through the limiting hole of the transmission box 12 and is fixedly connected to the first twist cover 26. Through this design, the first twist cover 26 drives the drive shaft 25 and the first bevel gear 24 to rotate in a limited position, so that the first bevel gear 24 meshes and drives the second bevel gear 23 to rotate.
[0020] Pushing screws 27 are fitted inside the fixed arm 13 on both sides of the outer wall of the symmetrical screw 21. The outer ends of the pushing screws 27 are fixedly connected to the inner side of the extension arm 14. This design enables the symmetrical screw 21 to drive the pushing screws 27 and the extension arm 14 to slide symmetrically, effectively preventing the cantilever arms on both sides of the shelf from shifting their center of gravity and tipping over.
[0021] The assembly mechanism 3 includes a limiting seat 31, which is sleeved on the outer wall of a pair of uprights 15. A connecting bolt 32 is inserted into the inner front wall of the limiting seat 31, and a second twist cap 33 is fixedly connected to the top of the connecting bolt 32. Through this design, the second twist cap 33 drives the connecting bolt 32 to rotate within the limiting seat 31.
[0022] A fixing screw cylinder 34 is threaded onto the lower outer wall of the plug bolt 32, and the bottom of the fixing screw cylinder 34 is fixedly mounted on the top front side of the base 11 and the transmission box 12. Through this design, the plug bolt 32 and the fixing screw cylinder 34 are used to stably and cumulatively mount the cantilever.
[0023] Working principle: When the extension arm 14 needs to be adjusted, the first twist cover 26 is rotated manually first. The first twist cover 26 drives the transmission shaft 25 to rotate in a limited position. The transmission shaft 25 drives the first bevel gear 24 to rotate synchronously. The first bevel gear 24 meshes and drives the second bevel gear 23 to rotate. The second bevel gear 23 drives the symmetrical screw 21 to rotate in a limited position. The symmetrical screw 21 drives the pusher cylinder 27 and the extension arm 14 to slide symmetrically, thus realizing the adjustment operation of the extension arm 14.
[0024] When it is necessary to install the cantilever, first insert a pair of uprights 15 into the corresponding inserts 16, and then rotate the second twist cover 33 clockwise. The second twist cover 33 drives the insertion bolt 32 to rotate within the limit seat 31, so that the insertion bolt 32 is screwed into the fixed screw cylinder 34, thus realizing the cantilever installation operation. The operation ends here.
[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
