Description

Technical Field

[0001] The invention belongs to the technical field of storage equipment, and in particular relates to a three-dimensional storage shelf and a storage method thereof. Background Art

[0002] Stereoscopic storage racks, also known as automated stereoscopic warehouses or high-bay warehouses, are an efficient storage solution that utilizes vertical space to maximize storage capacity. In large automated stereoscopic warehouses, there are dedicated lanes for automated guided vehicles to place goods in designated locations or to remove goods from them. However, traditional automated guided vehicles require wider lanes for vehicle driving, turning, and loading and unloading of goods, which increases the floor space of the racks and is not conducive to maximizing storage capacity. At the same time, traditional stereoscopic storage racks require special lifting equipment to facilitate the loading and unloading of goods at different heights by guided vehicles, which not only increases costs, but also further increases the floor space of the racks.

[0003] Therefore, there is a need for a three-dimensional storage shelf that can minimize aisle width, reduce shelf footprint, and maximize storage capacity in a limited space. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a three-dimensional storage shelf and a storage method thereof. The present invention can establish a minimum passage between storage racks, allowing the vehicle body to pass through while also conveniently allowing the vehicle body to be lifted vertically, thereby minimizing the floor space occupied by the storage racks. The three-dimensional storage shelf with maximized storage capacity in a limited space can improve space utilization and production efficiency at the same time.

[0006] The lifting mechanism can drive the vehicle body to vertically lift on the storage rack;

[0007] The loading vehicle can travel on the cleaning component, and the loading vehicle can drive the cleaning component when traveling on the cleaning component.

[0008] Through the above technical scheme, multiple storage racks are fixed on the floor of the warehouse in sequence, so that the gaps between the storage racks form a straight passage that only allows the vehicle body to pass through. When the vehicle body travels in the passage and reaches the target storage rack, the lifting mechanism is started, and the lifting mechanism can drive the vehicle body to vertically lift and lower on the storage rack. When the vehicle body reaches the target height, the load platform turns so that the loader points to the target storage rack, and then the loader is started to enter the storage rack. The loader enters the storage rack to load and unload goods. After the loading and unloading of goods is completed, the loader returns to the load platform, and then the lifting mechanism lowers the vehicle body to the ground, and the vehicle body can continue to travel, and then the next loading and unloading of goods is carried out, so that more storage racks can be displayed in a limited space, and the storage racks can be easily loaded and unloaded, effectively improving the space utilization rate of the warehouse.

[0009] Furthermore, the guide plate edge is provided with teeth, and a first adjusting gear is rotatably connected to one side of the guide plate at the bottom of the vehicle body, and the first adjusting gear is meshed with the teeth on the guide plate edge.

The inclined surfaces of the first inclined block and the second inclined block can fit together, and the climbing rack can mesh with the climbing gear.

[0014] Through the above technical solution, since the sliding block is vertically slidably connected to the four corners of the vehicle body, an electric push rod is fixedly connected to the side of the vehicle body, a first inclined block is fixedly connected to the top of the electric push rod, and a second inclined block is fixedly connected to the side of the sliding block, the inclined surfaces of the first inclined block and the second inclined block can fit together, so that when the electric push rod pushes the first inclined block to slide toward the second inclined block, the first inclined block can squeeze the second inclined block to realize the rise of the sliding block, and when the inclined surfaces of the first inclined block and the second inclined block are completely fitted together, the sliding block is locked, and when the first inclined block slides in the opposite direction, the second inclined block also descends, that is, the sliding block descends;

[0015] Since the climbing gear is rotatably connected to the top of the sliding block, a climbing motor is fixedly connected to the top of the sliding block, and the climbing motor shaft and the climbing gear shaft are connected by a transmission belt. The lifting rack can engage with the climbing gear, so that the climbing motor can drive the climbing gear to rotate through the transmission belt, and the rising of the sliding block can make the climbing gear enter the track groove, and the climbing gear engages with the climbing rack, so that the climbing gear rotates to drive the sliding block to rise and fall, that is, drive the vehicle body to rise and fall.

The edge of the rotating disk is provided with teeth. A second adjusting gear is rotatably connected to one side of the rotating disk on the top of the vehicle body, and the second adjusting gear is engaged with the teeth on the edge of the rotating disk.

Cleaning belts are wound around the first conveying roller and the second conveying roller. Both ends of the first conveying roller are fixedly connected to the first transmission wheel, and both ends of the second conveying roller are fixedly connected to the second transmission wheel. The first transmission wheel and the second transmission wheel are connected through a transmission chain. The transmission gear is rotatably connected to the inner wall of the load platform. The transmission gear consists of two groups, and the transmission gears are symmetrically arranged above the first conveying roller. Both ends of the first conveying roller are also fixedly connected to driven gears, and the driven gears are meshed with the transmission gears.

[0019] Through the above technical scheme, since the cleaning belt is wound around the first conveying roller and the second conveying roller, the first conveying roller is fixedly connected to the first transmission wheel at both ends, and the second conveying roller is fixedly connected to the second transmission wheel at both ends. The first transmission wheel and the second transmission wheel are connected by a transmission chain, and the transmission gear is rotatably connected to the inner wall of the load platform. There are two groups of transmission gears, and the transmission gears are symmetrically arranged above the first conveying roller. The first conveying roller is also fixedly connected to the driven gear at both ends, and the driven gear is meshed with the transmission gear, so that the rotation of the transmission gear can drive the driven gear to rotate, and the rotation of the driven gear can drive the first conveying roller to rotate, and the rotation of the first conveying roller can drive the first transmission wheel to rotate. The rotation of the first transmission wheel can drive the second transmission wheel to rotate through the transmission chain, that is, drive the second conveying roller to rotate, and then drive the cleaning belt to move, and the rotation direction of the transmission gear is opposite to that of the driven gear.

[0021] Through the above technical solution, since the driving rack is fixedly connected to both sides of the loading vehicle, the traveling roller is rotatably connected to the bottom of the loading vehicle, and the driving rack is meshed with the transmission gear, when the loading vehicle enters and exits the loading platform, the driving rack can drive the transmission gear to rotate, and then drive the cleaning belt to move, and the rotation direction of the transmission gear is opposite to the rotation direction of the driven gear, that is, the rotation direction of the transmission gear is opposite to the rotation direction of the first conveying roller and the second conveying roller, that is, the moving direction of the cleaning belt is opposite to the moving direction of the loading vehicle, so that the cleaning belt cleans the traveling roller, prevents the traveling roller from contaminating the storage rack, and reduces the cleaning burden of the storage rack. At the same time, the moving direction of the cleaning belt is opposite to the forward direction of the traveling roller, which can prevent the traveling roller from slipping, and help the loading vehicle to smoothly enter and exit the loading platform;

[0022] Since a plurality of scrapers are fixedly connected to the bottom of the load platform, when the cleaning belt moves below the first conveying roller and the second conveying roller, the scrapers can scrape and clean the cleaning belt.

[0023] Furthermore, the top of the loader is also fixedly connected to a lifting assembly, and the lifting assembly is symmetrically arranged in two groups on the top of the loader, and the lifting assembly includes a top plate, a bottom plate, a first strut group, a second strut group and a pin, one end of the first strut group is hinged to the bottom plate, the other end of the first strut group is slidably connected to the top plate, one end of the second strut group is hinged to the top plate, the other end of the second strut group is slidably connected to the bottom plate, and the first strut group and the second strut group are hinged in the middle by a pin.

[0024] Through the above technical solution, since one end of the first strut group is hinged to the bottom plate, the other end of the first strut group is slidably connected to the top plate, one end of the second strut group is hinged to the top plate, the other end of the second strut group is slidably connected to the bottom plate, and the first strut group and the second strut group are hinged through a pin shaft in the middle, the other end of the second strut group sliding on the bottom plate can drive the other end of the first strut group to slide on the top plate synchronously, and the distance between the top plate and the bottom plate changes accordingly.

[0025] Furthermore, a first slide groove is provided on the side of one end of the top plate, and the other end of the first strut group is slidably connected to the first slide groove; a second slide groove is provided on the side of one end of the bottom plate, and the other end of the second strut group is slidably connected to the second slide groove; a hydraulic push rod is also provided at one end of the bottom plate, and a cross beam is fixedly provided on the second strut group, and the hydraulic push rod can push the cross beam to slide horizontally.

[0026] Through the above technical scheme, since a first slide groove is provided on the side surface of one end of the top plate, the other end of the first support rod group is slidably connected to the first slide groove, a second slide groove is provided on the side surface of one end of the bottom plate, and the other end of the second support rod group is slidably connected to the second slide groove, a hydraulic push rod is also provided at one end inside the bottom plate, and a crossbeam is fixedly provided on the second support rod group, and the hydraulic push rod can push the crossbeam to slide horizontally, so that the hydraulic push rod pushes the crossbeam to move horizontally, which can drive the other end of the second support rod group to slide horizontally in the second slide groove, and then drive one end of the second support rod group to rotate on the top plate, so as to realize the rotation of one end of the first support rod group on the bottom plate, and the other end of the first support rod group slides horizontally in the first slide groove simultaneously;

[0027] When the hydraulic push rod is extended, the distance between the top plate and the bottom plate increases, and when the hydraulic push rod is shortened, the distance between the top plate and the bottom plate decreases, thereby achieving the lifting and lowering of the top plate.

[0028] A storage method comprises the following steps:

[0029] Step 1: Fix multiple storage racks on the floor of the warehouse in order, so that the gaps between the storage racks form a straight passage that only allows vehicles to pass through, and adjacent storage racks share a track groove, so that as many storage racks as possible can be placed in the warehouse, and goods can be placed on the storage racks;

[0030] Step 2: The vehicle automatically passes through the passage between the storage racks. When the vehicle needs to turn, the first adjusting gear drives the guide plate to rotate. The rotation of the guide plate can drive the driving wheel group to turn, thereby changing the driving direction of the vehicle, so that the vehicle can complete the turning without additional space;

[0031] Step 3: Before the vehicle body reaches the designated storage rack, the electric push rod is started, and the electric push rod slides horizontally to drive the first inclined block to squeeze the second inclined block, so that the sliding block rises, and the climbing rack is meshed with the climbing gear. At this time, the climbing motor is started to drive the vehicle body to rise and fall in front of the designated storage rack;

[0032] Step 4: After the vehicle body is raised to the specified height, the second adjusting gear is started, and the second adjusting gear drives the rotating disk to rotate, so that the loading vehicle is aligned with the specified storage rack;

[0033] Step 5: Start the loading vehicle, the loading vehicle enters the designated storage rack, and then start the lifting assembly to load the goods on the storage rack onto the loading vehicle, and then the loading vehicle unloads the goods onto the loading platform, or the loading vehicle transports the goods on the loading platform to the designated storage rack, and then the loading vehicle returns to the loading platform to realize the loading and unloading of goods;

[0034] Step 6. When the loader enters and exits the loading platform, the driving rack can drive the cleaning component to rotate, and the rotation direction of the cleaning component is opposite to the driving direction of the loader, so that the cleaning belt on the cleaning component can clean the driving roller on the loader to prevent contamination of the storage rack.

[0035] The beneficial effects of the present invention are as follows:

[0036] (1) In the present invention, multiple storage racks are fixed on the floor of the warehouse in sequence, so that the gaps between the storage racks form a straight passage through which only vehicles can pass. When the vehicle travels in the passage and reaches the target storage rack, the lifting mechanism is activated, and the lifting mechanism can drive the vehicle to rise and fall vertically on the storage rack, thereby maximizing the area occupied by the storage racks and maximizing the storage capacity of the three-dimensional storage rack in a limited space, thereby improving space utilization and production efficiency;

[0037] (2) In the present invention, when the loader enters and exits the loading platform, the driving rack can drive the transmission gear to rotate, and then drive the cleaning belt to move. The rotation direction of the transmission gear is opposite to that of the driven gear, that is, the rotation direction of the transmission gear is opposite to that of the first conveying roller and the second conveying roller, that is, the moving direction of the cleaning belt is opposite to that of the loader. The cleaning belt cleans the traveling roller, prevents the traveling roller from contaminating the storage rack, and reduces the cleaning burden of the storage rack. At the same time, the moving direction of the cleaning belt is opposite to the forward direction of the traveling roller, which can prevent the traveling roller from slipping and help the loader to smoothly enter and exit the loading platform.

[0058] In this embodiment, multiple storage racks 1 are fixed on the floor of the warehouse in sequence, so that the gaps between the storage racks 1 form a straight passage through which only the vehicle body 2 can pass. When the vehicle body 2 travels in the passage and reaches the target storage rack 1, the lifting mechanism 3 is started, and the lifting mechanism 3 can drive the vehicle body 2 to rise and fall vertically on the storage rack 1.

The first support rod group 523 and the second support rod group 524 are hinged in the middle through a pin 525.

[0074] A first slide groove 5211 is arranged on the side of one end of the top plate 521, and the other end of the first strut group 523 is slidably connected to the first slide groove 5211. A second slide groove 5222 is arranged on the side of one end of the bottom plate 522, and the other end of the second strut group 524 is slidably connected to the second slide groove 5222. A hydraulic push rod 5221 is also arranged on one end of the bottom plate 522, and a cross beam 5241 is fixedly arranged on the second strut group 524. The hydraulic push rod 5221 can push the cross beam 5241 to slide horizontally.

[0075] In this embodiment, the hydraulic push rod 5221 pushes the crossbeam 5241 to move horizontally, thereby driving the other end of the second support rod group 524 to slide horizontally in the second slide groove 5222, and then driving one end of the second support rod group 524 to rotate on the top plate 521, and synchronously realizes that one end of the first support rod group 523 rotates on the bottom plate 522, and the other end of the first support rod group 523 slides horizontally in the first slide groove 5211;

[0076] When the hydraulic push rod 5221 is extended, the distance between the top plate 521 and the bottom plate 522 increases, and when the hydraulic push rod 5221 is shortened, the distance between the top plate 521 and the bottom plate 522 decreases, thereby achieving the lifting and lowering of the top plate 521.

[0077] A storage method comprises the following steps:

[0078] Step 1: fix multiple storage racks 1 on the floor of the warehouse in order, so that the gaps between the storage racks 1 form a straight passage through which only the vehicle body 2 can pass, and adjacent storage racks 1 share a track groove 11, so that as many storage racks 1 as possible can be placed in the warehouse, and goods can be placed on the storage racks 1;

[0079] Step 2: The vehicle body 2 automatically passes through the passage between the storage racks 1. When the vehicle body 2 needs to turn, the first adjusting gear 71 drives the guide plate 7 to rotate. The rotation of the guide plate 7 can drive the driving wheel group to turn, thereby changing the driving direction of the vehicle body 2, so that the vehicle body 2 can complete the turning without additional space;

[0080] Step 3: Before the vehicle body 2 reaches the designated storage rack 1, the electric push rod 32 is started, and the electric push rod 32 slides horizontally to drive the first inclined block 321 to squeeze the second inclined block 311, so that the sliding block 31 rises, and the climbing rack 111 is meshed with the climbing gear 33. At this time, the climbing motor 34 is started to drive the vehicle body 2 to rise and fall in front of the designated storage rack 1;

[0081] Step 4: After the vehicle body 2 is raised to a specified height, the second adjusting gear 42 is started, and the second adjusting gear 42 drives the rotating disk 41 to rotate, so that the loading vehicle 5 is aligned with the specified storage rack 1;

[0082] Step 5: Start the loading vehicle 5, the loading vehicle 5 enters the designated storage rack 1, and then start the lifting assembly 52 to load the goods on the storage rack 1 onto the loading vehicle 5, and then the loading vehicle 5 unloads the goods onto the load platform 4, or the loading vehicle 5 transports the goods on the load platform 4 to the designated storage rack 1, and then the loading vehicle 5 returns to the load platform 4 to realize the loading and unloading of goods;

[0083] Step 6. When the loading cart 5 enters and exits the loading platform 4, the driving rack 51 can drive the cleaning component 6 to rotate, and the rotation direction of the cleaning component 6 is opposite to the driving direction of the loading cart 5, so that the cleaning belt on the cleaning component 6 can clean the driving roller 53 on the loading cart 5 to prevent contamination of the storage rack 1.

[0084] Working principle:

[0085] During operation, a plurality of storage racks 1 are fixed on the floor of the warehouse in sequence, so that the gaps between the storage racks 1 form a straight passage through which only the vehicle body 2 can pass, and the vehicle body 2 travels in the passage;

[0086] When steering is required, the first adjusting gear 71 rotates to drive the guide plate 7 to steer, and the steering of the guide plate 7 drives the driving wheel group to steer, thereby driving the vehicle body 2 to steer, so that the vehicle body 2 can complete the steering without requiring additional space;

[0087] After the vehicle body 2 reaches the target storage rack 1, the electric push rod 32 is started, and the electric push rod 32 pushes the first inclined block 321 to slide toward the second inclined block 311. The first inclined block 321 can squeeze the second inclined block 311 to achieve the rise of the sliding block 31. When the inclined surface of the first inclined block 321 is completely in contact with the inclined surface of the second inclined block 311, the sliding block 31 is locked, and the rise of the sliding block 31 can make the climbing gear 33 enter the track groove 11, and the climbing gear 33 is meshed with the climbing rack 111;

[0088] At this time, the climbing motor 34 is started to drive the climbing gear 33 to rotate, and the climbing gear 33 rotates to drive the sliding block 31 to rise, that is, to drive the vehicle body 2 to rise;

[0089] After the vehicle body 2 is raised to the target height, the rotation of the second adjusting gear 42 can drive the rotating disk 41 to rotate, and the rotation of the rotating disk 41 can drive the load platform 4 to rotate, so as to realize the steering of the load platform 4, so that the loading vehicle 5 faces the target direction;

[0090] At this time, the loading vehicle 5 is started, and when the goods on the storage rack 1 need to be loaded onto the loading vehicle 5, the hydraulic push rod 5221 extends, the distance between the top plate 521 and the bottom plate 522 increases, the top plate 521 rises to lift the goods, and then the loading vehicle 5 returns to the load platform 4, the hydraulic push rod 5221 retracts, the distance between the top plate 521 and the bottom plate 522 decreases, the top plate 521 descends, and the goods fall onto the load platform 4;

[0091] When the goods on the load platform 4 need to be placed on the storage rack 1, the hydraulic push rod 5221 extends, the distance between the top plate 521 and the bottom plate 522 increases, the top plate 521 rises to lift the goods, and then the loader 5 enters the storage rack 1, the hydraulic push rod 5221 retracts, the gap between the top plate 521 and the bottom plate 522 becomes smaller, the top plate 521 descends, the goods are placed on the storage rack 1, and the loader 5 returns to the load platform 4;

[0092] When the loader 5 enters and exits the loading platform 4, the driving rack 51 can drive the transmission gear 64 to rotate, and then drive the cleaning belt to move, and the rotation direction of the transmission gear 64 is opposite to the rotation direction of the driven gear 612, that is, the rotation direction of the transmission gear 64 is opposite to the rotation direction of the first conveying roller 61 and the second conveying roller 62, that is, the moving direction of the cleaning belt is opposite to the moving direction of the loader 5, so that the cleaning belt cleans the driving roller 53, prevents the driving roller 53 from contaminating the storage rack 1, and reduces the cleaning burden of the storage rack 1. At the same time, the moving direction of the cleaning belt is opposite to the forward direction of the driving roller 53, which can prevent the driving roller 53 from slipping, and help the loader 5 smoothly enter and exit the loading platform 4;

[0093] A plurality of scrapers 43 are fixedly connected to the bottom of the load platform 4 so that when the cleaning belt moves below the first conveying roller 61 and the second conveying roller 62, the scrapers 43 can scrape and clean the cleaning belt;

[0094] After loading and unloading is completed, the climbing motor 34 is started to drive the vehicle body 2 to descend. After the vehicle body 2 descends to the ground, the electric push rod 32 is started, and the electric push rod 32 drives the first inclined block 321 to slide in the opposite direction, and the second inclined block 311 descends accordingly, that is, the sliding block 31 descends. At this time, the vehicle body 2 can travel normally in the channel, and the vehicle body 2 can be loaded and unloaded for the next target;

[0095] Both the first adjusting gear 71 and the second adjusting gear 42 can be driven to rotate by the control motor to realize automatic steering of the vehicle body 2 and the load platform 4 .

[0096] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
