Description

Technical Field

[0001] This utility model relates to the field of logistics and warehousing technology, and in particular to a three-way stacking gantry for upward movement of people. Background Technology

[0002] With the deep integration of technologies such as the Internet of Things and artificial intelligence, the logistics and warehousing industry is undergoing an unprecedented wave of transformation. In this intelligent transformation, automated storage and retrieval systems (AS / RS) have become the core development direction of modern warehousing systems due to their advantages of high efficiency, precision, and high space utilization. Stacker cranes, as the executors of AS / RS, undertake the critical tasks of goods storage, retrieval, and handling.

[0003] Related technology can be found in Chinese Patent No. CN211470675U, which discloses a stacker crane for logistics warehouses, belonging to the field of stacker cranes. It includes a machine body with a lifting rail on one side and a lifting frame on the other side. A sliding rod is fixed inside the lifting frame. When lifting goods, the bottom of the goods contacts a gravity sensor and applies pressure. The gravity sensor transmits the value to the controller. When the value exceeds a preset threshold, the controller activates an alarm light. When the alarm light illuminates, the operator knows that the goods have exceeded the maximum lifting capacity and abandons further lifting. This avoids the danger of fork deformation and tipping due to unstable lifting, improving safety. The stacker crane also includes an electric push rod and a pressure plate. When lifting goods, the operator activates the electric push rod, which retracts, causing the pressure plate to press down on the goods, improving stability during lifting and further enhancing the safety of the stacker crane.

[0004] Regarding the aforementioned technologies, stacker cranes utilize lifting frames to achieve precise vertical lifting of goods. While this unidirectional adjustment mechanism can meet basic warehousing operation needs, in actual use, as the complexity of warehousing operations increases, and the sizes and specifications of goods become more diverse, as well as the layout of warehouses become more varied, the flexibility of stacker cranes becomes poor. Utility Model Content

[0005] To improve the flexibility of using stacking gantry, the present application provides an upward three-way stacking gantry.

[0006] The applicant provides an upward three-way stacking gantry, which adopts the following technical solution: The three-way stacking gantry for upward movement includes a mounting frame. A driver's cab is located on one side of the mounting frame. A lifting frame is located between the driver's cab and the mounting frame, sliding vertically to the mounting frame. The lifting frame is used to move the driver's cab vertically. A rotating component is located on the side of the lifting frame closest to the driver's cab, rotating the cab. A sliding block is located at the end of the driver's cab furthest from the lifting frame, sliding laterally to the driver's cab. A translation frame is fixedly mounted at the end of the sliding block opposite to the driver's cab. A motor is fixedly mounted on one side of the translation frame. A connecting plate is fixedly mounted on the output shaft of the motor, and a hydraulic cylinder is fixedly mounted inside the connecting plate. A sprocket is provided at the output end of the hydraulic cylinder, and a chain is provided on one side of the sprocket. The chain meshes with the sprocket, and one end of the chain is fixedly connected to the connecting plate. A lifting plate is fixedly provided at the end of the chain away from the connecting plate. The lifting plate is slidably connected to the connecting plate along the length of the connecting plate. A motor is fixedly provided at the end of the lifting plate away from the connecting plate. A double-acting screw is fixedly provided on the output shaft of the motor. The double-acting screw is rotatably connected to the lifting plate. There are moving blocks at both ends of the double-acting screw. The moving blocks are threadedly connected to the double-acting screw and are slidably connected to the lifting plate in the transverse direction. Forks are fixedly provided on one side of each of the two moving blocks.

[0007] By adopting the above technical solution, the mounting frame supports the lifting frame, the lifting plate drives the cab to rise and fall, facilitating the adjustment of the cab's position and improving the flexibility of equipment use. The translation frame drives the connecting plate to move laterally, which in turn drives the lifting plate to move laterally, and the lifting plate to move the forks laterally, facilitating the adjustment of the fork position. When the motor starts, it drives the connecting plate to rotate, which in turn drives the lifting plate to rotate, and the lifting plate to rotate the forks, thus adjusting the fork angle. When the hydraulic cylinder starts, it drives the sprocket to rise and fall, which in turn drives the chain to rise and fall, which in turn drives the lifting plate to rise and fall, and the lifting plate to move the forks, thus adjusting the fork height. When the motor starts again, it drives the bidirectional screw to rotate, the lifting plate limits the moving blocks, and the bidirectional screw rotates the two moving blocks to move laterally, allowing the two moving blocks to move closer or further apart. The lateral movement of the moving blocks drives the forks to move laterally, thus adjusting the distance between the two forks, adapting to the handling of objects of different sizes and improving the flexibility of gantry use.

[0008] Optionally, the lifting frame includes a mast one, a mast two, two hydraulic cylinders two, two hydraulic cylinders three, two sprockets two, two chains two, two sprockets three, and two chains three. The two hydraulic cylinders two are fixed at both ends of the mounting frame. The output ends of the sprockets two and the hydraulic cylinders two are coaxial. The sprockets two and the chains two correspond one-to-one and mesh with each other. One end of the chains two is fixedly connected to the mounting frame. The mast one is fixed at the end of the chains two away from the mounting frame. The two hydraulic cylinders three are fixed at the side of the mast one away from the mounting frame. The output ends of the sprockets three and the hydraulic cylinders three are coaxial. The sprockets three and the chains three correspond one-to-one and mesh with each other. One end of the chains three is fixedly connected to the mast one. The mast two is fixed at the end of the chains three away from the mast. A mounting plate is fixed on one side of the mast two and is rotatably connected to the cab.

[0009] By adopting the above technical solution, the second hydraulic cylinder starts and drives the second sprocket to rotate. The rotation of the second sprocket causes the second chain to move vertically. The vertical movement of the second chain causes the first gantry to rise and fall relative to the mounting frame. The third hydraulic cylinder starts and drives the third sprocket to rotate. The rotation of the third sprocket causes the third chain to move vertically. The vertical movement of the third chain causes the mounting plate to rise and fall. The rise and fall of the mounting plate causes the cab to rise and fall, thereby realizing the adjustment of the cab position. This design can achieve a larger vertical lifting range in a limited space and improve the flexibility of equipment use.

[0010] Optionally, the rotating component includes two motors, two worms, a worm wheel, and a movable plate. The two motors are fixed to the upper end of the mounting plate. The worms correspond one-to-one with the motors and are coaxially fixed with the output shaft of the corresponding motor. The worm wheel is located between the two worms and meshes with the two worms. The movable plate is fixed to the upper end of the worm wheel and is fixedly connected to the cab.

[0011] By adopting the above technical solution, the three motors start and drive the corresponding worm gears to rotate. When the two worm gears rotate in opposite directions, they drive the worm wheel to rotate. The rotation of the worm wheel drives the moving plate to rotate, and the rotation of the moving plate drives the cab to rotate. The cab angle can be flexibly adjusted, making it easier for operators to observe the goods and operate the stacking operation from different directions, thus improving operational flexibility and convenience.

[0012] Optionally, the sliding block includes a hydraulic cylinder four, a sliding plate, and a fixed plate. The fixed plate is fixed on the side of the cab away from the lifting frame, the hydraulic cylinder four is fixed on one side of the fixed plate, the sliding plate is coaxially fixed with the output end of the hydraulic cylinder four, and the sliding plate is slidably connected to the fixed plate along the length of the fixed plate.

[0013] By adopting the above technical solution, the hydraulic cylinder four-drive slide plate slides along the length of the fixed plate, which can realize the lateral position adjustment of the translation frame. It can flexibly change the lateral position of the forks to adapt to different cargo placement positions and improve the accuracy of cargo stacking.

[0014] Optionally, two sliders are fixed at the upper end of the slide plate, with the two sliders located at the two ends of the slide plate respectively. A groove is provided on the surface of the fixed plate, and the sliders are located in the groove and are slidably connected to the fixed plate along the length of the groove.

[0015] By adopting the above technical solution, the slider slides in the groove, making the slide plate slide more smoothly and stably on the fixed plate, reducing the jamming and deviation during the sliding process of the slide plate, and ensuring the reliability of the working of the sliding block.

[0016] Optionally, the translation frame includes a connecting block, a fourth motor, two gears, two racks, and a connecting rod. The connecting block is located on the side of the sliding block away from the cab. The connecting block is slidably connected to the sliding block along its length. The fourth motor is fixed to the upper end of the connecting block. The connecting rod is coaxially fixed to the fourth motor and is vertically arranged. The two gears are fixed to both ends of the connecting rod. The two racks are fixed to the side of the sliding block away from the cab. The gears and racks correspond one-to-one and mesh with each other.

[0017] By adopting the above technical solution, the connecting block supports the fourth motor. When the fourth motor starts, it drives the connecting rod to rotate. The rotation of the connecting rod drives the two gears to rotate. The rotation of the gears causes the connecting block to slide along the length of the sliding block, thereby realizing the lateral position adjustment of the translation frame and increasing the flexibility of the stacking gantry operation and the range of goods handling.

[0018] Optionally, a translation roller is provided on the side of the connecting block near the sliding block. The translation roller is rotatably connected to the connecting block. A slide rail is provided on the side of the sliding block near the connecting block. The translation roller is located inside the slide rail and is slidably connected to the slide rail along the length of the slide rail.

[0019] By adopting the above technical solution, the connecting block cooperates with the sliding block's slide rail through the translation roller, making the translation frame slide more smoothly relative to the sliding block, reducing friction and wear, and improving the stability and reliability of equipment operation.

[0020] Optionally, a hydraulic cylinder five is fixedly installed at the upper end of the lifting plate. The hydraulic cylinder five is vertically arranged, and a baffle is fixedly installed at the output end of the hydraulic cylinder five. The baffle cooperates with the forks to limit the object.

[0021] By adopting the above technical solution, the hydraulic cylinder five starts to drive the baffle to rise and fall, so that the baffle and the fork cooperate with each other, which can effectively reduce the probability of objects slipping or shaking during the handling process, and improve the stability and safety of cargo handling.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The motor starts and drives the double-acting screw to rotate. The lifting plate limits the movement of the moving blocks. The rotation of the double-acting screw moves the two moving blocks laterally, allowing the two moving blocks to move closer or further apart. The movement of the moving blocks laterally drives the forks to move laterally, allowing the distance between the two forks to be adjusted to accommodate the handling of objects of different sizes and improve the flexibility of the mast. 2. The slider slides within the groove, making the slide plate slide more smoothly and stably on the fixed plate, reducing the jamming and offset during the sliding process, and ensuring the reliability of the slider block's operation; 3. The hydraulic cylinder five starts and drives the baffle to rise and fall, so that the baffle and the forks work together to effectively reduce the probability of objects slipping or shaking during handling and improve the stability of cargo handling.

[0029] The present application will be further described in detail below with reference to all the accompanying drawings.

[0030] The embodiments of this application disclose an upward three-way stacking gantry. Example

[0031] Reference Figure 1 and Figure 2 The three-way stacking gantry for upward movement includes a mounting frame 1. A gantry 111 is provided on one side of the mounting frame 1. Two hydraulic cylinders 118 are fixed at both ends of the mounting frame 1. A sprocket 114 is provided at the output end of the hydraulic cylinder 118. A chain 115 is provided on one side of the sprocket 114. The sprocket 114 and the chain 115 mesh. One end of the chain 115 is fixedly connected to the mounting frame 1. When the hydraulic cylinder 118 is started, it drives the sprocket 114 to rotate. The rotation of the sprocket 114 drives the chain 115 to move vertically. The end of the chain 115 away from the mounting frame 1 is fixed to the gantry 111. The movement of the chain 115 along the lateral direction drives the gantry 111 to move horizontally.

[0032] Reference Figure 1 and Figure 2 Hydraulic cylinders 113 are fixed at both ends of gantry 111. A sprocket 116 is rotatably connected to the output end of each hydraulic cylinder 113. A chain 117 is located on the outer side of the sprocket 116, meshing with it. One end of the chain 117 is fixedly connected to gantry 111. When hydraulic cylinders 113 are activated, they drive the sprocket 116 to rotate. This rotation of the sprocket 116 drives the chain 117 to move vertically. A gantry 2 112 is fixed to the end of the chain 117 furthest from gantry 111. The vertical movement of the third 117 causes the second gantry 112 to rise and fall. A mounting plate 121 is fixed on one side of the second gantry 112. The vertical movement of the second gantry 112 causes the mounting plate 121 to move vertically. A cab 12 is provided on one side of the mounting plate 121. The cab 12 is rotatably connected to the mounting plate 121. The rise and fall of the mounting plate 121 causes the cab 12 to rise and fall, thereby adjusting the position of the cab 12. This design can achieve a larger vertical lifting range in a limited space and improve the flexibility of equipment use.

[0033] Reference Figure 3Two motors 122 are fixedly mounted on the upper end of the mounting plate 121. The two motors 122 are located at opposite ends of the mounting plate 121. Worms 123 are fixedly mounted on the output shafts of the motors 122. When the motors 122 are started, they drive the corresponding worms 123 to rotate. A worm wheel 124 is provided between the two worms 123. A movable plate 125 is fixedly mounted on the upper end of the worm wheel 124. The movable plate 125 is fixedly connected to the cab 12. The worm wheel 124 meshes with the two worms 123. When the two worms 123 rotate in the same direction, the worm wheel 124 moves along the worm 123. The worm gear 124 moves along the length direction, which in turn drives the moving plate 125 to move laterally. The moving plate 125 moves laterally, which in turn drives the cab 12 to move laterally, making it easier to adjust the position of the cab 12. When the two worm gears 123 rotate in opposite directions, they drive the worm gear 124 to rotate. The rotation of the worm gear 124 drives the moving plate 125 to rotate, which in turn drives the cab 12 to rotate. This allows for flexible adjustment of the angle of the cab 12, making it easier for operators to observe the goods and perform stacking operations from different directions, thus improving operational flexibility and convenience.

[0034] Reference Figure 4 A sliding block 13 is provided at the end of the cab 12 away from the lifting frame 11. The sliding block 13 includes a hydraulic cylinder 131, a sliding plate 132, and a fixing plate 133. The fixing plate 133 is fixed on the side of the cab 12 away from the lifting frame 11. The hydraulic cylinder 131 is fixed on one side of the fixing plate 133. The fixing plate 133 supports the hydraulic cylinder 131. The sliding plate 132 is coaxially fixed with the output end of the hydraulic cylinder 131. The hydraulic cylinder 131 drives the sliding plate 132 to slide along the length of the fixing plate 133, which can realize the lateral position adjustment of the sliding plate 132. It can flexibly change the lateral position of the forks 16 to adapt to different cargo placement positions and improve the accuracy of cargo stacking.

[0035] Reference Figure 4 Two sliders 134 are fixedly provided at the upper end of the slide plate 132. The two sliders 134 are located at the two ends of the slide plate 132 respectively. The surface of the fixed plate 133 is provided with a groove. The sliders 134 are located in the groove and are slidably connected to the fixed plate 133 along the length of the groove. This makes the slide plate 132 slide more smoothly and stably on the fixed plate 133, reduces the jamming and offset during the sliding process of the slide plate 132, and ensures the stability of the working of the sliding block 13.

[0036] Reference Figure 5A connecting block 14 is provided on the side of the sliding block 13 away from the cab 12. The connecting block 14 is slidably connected to the sliding block 13 along its length. A motor 141 is fixedly mounted on the upper end of the sliding block 13, supporting the motor 141. A connecting rod 144 is fixedly mounted on the output shaft of the motor 141. When the motor 141 starts, it drives the connecting rod 144 to rotate. Gears 142 are fixedly mounted on both ends of the connecting rod 144. The rotation of the connecting rod 144 drives the gears 142 to rotate. Two racks 143 are fixedly mounted on the side of the sliding block 13 away from the cab 12. The racks 143 correspond one-to-one with the gears 142, and the gears 142 mesh with their corresponding racks 143. The rotation of the rack 143 causes the connecting block 14 to slide along the length of the sliding block 13. A connecting plate 15 is provided on one side of the connecting block 14. The connecting block 14 moves laterally, causing the connecting plate 15 to move laterally as well. A lifting plate 152 is provided on the side of the connecting plate 15 away from the connecting block 14. The lifting plate 152 is slidably connected to the connecting plate 15 along the length of the connecting plate 15. The connecting plate 15 moves laterally, causing the lifting plate 152 to move laterally as well. A fork 16 is provided on the side of the lifting plate 152 away from the connecting plate 15. The lifting plate 152 moves laterally, causing the fork 16 to move laterally as well, thus realizing the lateral position adjustment of the fork 16, increasing the flexibility of the stacking gantry operation and the range of goods handling.

[0037] Reference Figure 5 The connecting block 14 is provided with a translation roller 146 on the side near the sliding block 13.

The translation roller 146 is located inside the slide rail 145 and is slidably connected to the slide rail 145 along the length of the slide rail 145. The connecting block 14 cooperates with the slide rail 145 of the sliding block 13 through the translation roller 146, so that the sliding of the translation frame relative to the sliding block 13 is smoother, reducing friction and wear, and improving the stability and reliability of the equipment operation.

[0038] Reference Figure 5A motor 151 is fixed on one side of the connecting block 14. The output shaft of the motor 151 is coaxially fixed with the connecting plate 15. When the motor 151 starts, it drives the connecting plate 15 to rotate. The rotation of the connecting plate 15 drives the lifting plate 152 to rotate. The rotation of the lifting plate 152 drives the fork 16 to rotate, thereby realizing the adjustment of the angle of the fork 16 and improving the flexibility of equipment use. A motor 161 is fixedly mounted on one end of the lifting plate 152 away from the connecting plate 15. A double-acting screw 162 is fixedly mounted on the output shaft of the motor 161. The double-acting screw 162 is rotatably connected to the lifting plate 152. When the motor 161 starts, it drives the double-acting screw 162 to rotate. Both ends of the double-acting screw 162 are provided with moving blocks 163. The moving blocks 163 are threadedly connected to the double-acting screw 162, and the moving blocks 163 are slidably connected to the lifting plate 152 in the lateral direction. The lifting plate 152 limits the moving blocks 163. When the double-acting screw 162 rotates, the two moving blocks 163 move laterally, so that the two moving blocks 163 move closer or further away from each other. The moving blocks 163 correspond one-to-one with the forks 16, and the moving blocks 163 are fixedly connected to the forks 16. The lateral movement of the moving blocks 163 drives the forks 16 to move laterally, so as to adjust the distance between the two forks 16, adapt to the handling of objects of different sizes, and improve the flexibility of the mast.

[0039] Reference Figure 5 A hydraulic cylinder 155 is fixedly installed at the upper end of the lifting plate 152. The hydraulic cylinder 155 is vertically arranged, and a baffle 156 is fixedly installed at the output end of the hydraulic cylinder 155. When the hydraulic cylinder 155 is activated, it drives the baffle 156 to rise or fall, so that the baffle 156 cooperates with the forks 16. This can effectively reduce the probability of objects slipping or shaking during transportation, and improve the stability and safety of cargo transportation. The implementation principle of the three-way stacking gantry of this application embodiment is as follows: the lifting frame 11 drives the cab 12 to rise and fall, the hydraulic cylinder 1 starts and drives the sprocket 154 to rotate, the sprocket 154 rotates and drives the chain 153 to rise and fall, the chain 153 rises and falls and drives the lifting plate 152 to rise and fall, the lifting plate 152 rises and falls and drives the forks 16 to rise and fall, realizing the adjustment of the height of the forks 16.
