Description

Technical Field

[0001] This utility model relates to the field of logistics and warehousing technology, and in particular to an intelligent cargo transportation device. Background Technology

[0002] The logistics vehicles used by existing express delivery and logistics stations for picking up goods are generally complex in structure. During normal use, they also need to have the ability to visually recognize and plan routes to unload goods from different locations. At the same time, they place extremely high demands on the data processing capabilities of the control unit, which leads to excessively high production costs and high repair costs after damage. Moreover, their single transport capacity is insufficient, resulting in low picking efficiency when a single user needs to pick up multiple items. In addition, in order to increase the storage capacity, the cabinets need to be set up to be tall, but most logistics vehicles cannot be adjusted to different heights, so they cannot accommodate goods of different heights. Furthermore, when transporting goods in tall cabinets, a large height and volume are required, which makes the problem of space occupation very prominent. Utility Model Content

[0007] Furthermore, the conveying mechanism includes a conveyor belt, a support frame, a third motor, a third sprocket, and a second chain. The third motor is mounted on the lifting frame, and the support frame is mounted on the lifting frame. The support frame slides up and down relative to the lifting frame. The output end of the third motor is provided with the third sprocket, and the support frame is provided with a fourth sprocket. The second chain is connected to the third sprocket and the fourth sprocket respectively. Several rotating shafts are passed through the support frame, and the rotating shafts rotate relative to the support frame. The fourth sprocket is fixedly connected to one of the rotating shafts. The conveyor belt is sleeved on the rotating shaft. The third motor is electrically connected to an external power supply and signal-connected to the control mechanism.

[0008] Furthermore, the control mechanism includes a motor controller, a main controller, and a first infrared sensor. The motor controller and the main controller are both mounted on the frame, and the first infrared sensor is mounted on the support frame.

[0009] Furthermore, the control mechanism also includes a first limit switch and a second limit switch. The first limit switch is disposed on the frame, and the second limit switch is disposed at the end of the frame. During the upward movement, the second sprocket assembly can contact the first limit switch and send the signal generated upon contact to the first motor through the main controller.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model discloses an intelligent controllable mobile lifting and conveying platform device. When goods need to be retrieved, the control mechanism controls the movement of the walking mechanism on the frame, causing the device to move to the position corresponding to the goods to be retrieved. Then, the control mechanism controls the start of the first motor. The rotation of the first sprocket on the first motor drives the first chain to rotate, which in turn drives the first chain to rotate. This causes the first chain to drive the first sprocket group, the second sprocket group, and the second sprocket to rotate forward or in reverse. Through the cooperation of the first chain, the first sprocket group, the second sprocket group, and the second sprocket, the conveying mechanism moves up and down on the lifting frame, allowing the conveying mechanism to reach different heights and to accommodate goods of different heights onto the conveying mechanism. After the conveying mechanism reaches its maximum height on the lifting frame, if it is necessary to accommodate goods at a higher position, the first sprocket continues to rotate, causing the first chain, the first sprocket group, the second sprocket group, and the second sprocket to work together to lift the lifting frame. This allows the lifting frame to move continuously upwards on the frame until it reaches a higher height to accommodate goods at a higher position. When it is necessary to transport the accommodated goods out, the control mechanism controls the movement of the traveling mechanism, causing the traveling mechanism to move the device to a suitable position for unloading. By using this device, it is not only small in size, effectively reducing space occupation, but also capable of unloading goods at different heights and positions, giving it the advantage of a wider working coverage area.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1 to 5An intelligent cargo transportation device includes a frame 1, a traveling mechanism, and a lifting mechanism. The traveling mechanism is located at the bottom of the frame 1, and the lifting mechanism is mounted on the frame 1 and moves vertically relative to the frame 1. The lifting mechanism is equipped with a conveying mechanism. The lifting mechanism includes a lifting frame 2, a first motor 3, a first sprocket 4, a second sprocket 5, a first chain 6, a first sprocket assembly 7, and a second sprocket assembly 8. One end of the first chain 6 can be fixed to the frame 1, and a suspension part can be provided on the frame 1. The other end of the first chain 6 is a free end, and the first chain 6 can be hung on the suspension part. The first sprocket assembly 7 and the second sprocket assembly 8 can each be composed of two identical fifth sprockets. The lifting frame 2 is mounted on the frame 1 and slides vertically relative to the frame 1. The first sprocket set 7 is located at the top of the lifting frame 2, and the second sprocket set 8 is located at the bottom of the lifting frame 2. The first motor 3 is mounted on the frame 1, and the output shaft of the first motor 3 is connected to the first sprocket 4. The first sprocket 4, the first sprocket set 7, and the second sprocket set 8 are all connected to the first chain 6. The second sprocket 5 is mounted on the conveying mechanism, which slides vertically relative to the lifting frame 2. The first chain 6 is connected to the second sprocket 5. A control mechanism is provided on the frame 1. The traveling mechanism, lifting mechanism, conveying mechanism, and control mechanism are all electrically connected to an external power supply. The mechanism is signal-connected to the walking mechanism, lifting mechanism, and conveying mechanism respectively. When goods need to be retrieved, the control mechanism controls the walking mechanism on the frame 1 to move, so that the device moves to the position corresponding to the goods to be retrieved. Then, the control mechanism controls the first motor 3 to start. The rotation of the first sprocket 4 on the first motor 3 drives the first chain 6 to rotate, which in turn drives the first sprocket group 7, the second sprocket group 8, and the second sprocket 5 to rotate in the forward or reverse direction. The cooperation of the first chain 6, the first sprocket group 7, the second sprocket group 8, and the second sprocket 5 enables the... The conveying mechanism moves up and down on the lifting frame 2, allowing it to reach different heights and accommodate goods of varying heights. Once the conveying mechanism reaches its maximum height on the lifting frame 2, if goods at higher positions need to be accommodated, the first sprocket 4 continues to rotate. This causes the first chain 6, the first sprocket set 7, the second sprocket set 8, and the second sprocket 5 to work together to lift the lifting frame 2. The lifting frame 2 then continues to move upwards on the frame 1 until it reaches higher heights to accommodate goods at higher positions. When the accommodated goods need to be transported out, the control mechanism controls the movement of the traveling mechanism.The walking mechanism moves the device to a suitable position, allowing unloading to proceed. This device is compact, effectively reducing space requirements, and can unload goods at different heights and positions, offering a wider operational coverage.

[0023] Specifically, the walking mechanism includes a drive axle 9, which is fixed to the frame 1 by several first fixing clamps 11. The drive axle 9 receives power from a second motor 12. A drive wheel 13 is connected to the power output end of the drive axle 9. Several second fixing clamps 14 are provided at the bottom of the frame 1, and a rotating shaft 15 is provided between the second fixing clamps 14. Driven wheels 16, which rotate relative to the rotating shaft 15, are provided at both ends of the rotating shaft 15. Both the drive wheel 13 and the driven wheel 16 have annular grooves 17 on their surfaces. Furthermore, annular grooves 17 can be provided on the drive wheel 13. A track (not shown) is provided at the bottom of the driven wheel 16 and the second motor 12. The first motor 3 is electrically connected to an external power source and signal-connected to the control mechanism. The power output of the second motor 12 is sent to the drive axle 9, causing the drive axle 9 to drive the driving wheel 13 to rotate, thereby causing the driven wheel 16 to rotate synchronously. The annular groove 17 on the surface of the driving wheel 13 and the driven wheel 16 can move along the track, thereby controlling the device to move to a designated position, thus completing the receiving and output of goods.

[0024] Specifically, the conveying mechanism includes a conveyor belt 18, a support frame 19, a third motor 20, a third sprocket 21, and a second chain 23. The third motor 20 is mounted on the lifting frame 2, and the support frame 19 is mounted on the lifting frame 2. The support frame 19 slides up and down relative to the lifting frame 2. The output end of the third motor 20 is provided with the third sprocket 21, and the support frame 19 is provided with a fourth sprocket 22. The second chain 23 is connected to the third sprocket 21 and the fourth sprocket 22 respectively. A plurality of rotating shafts 24 are threaded through the support frame 19, and the rotating shafts 24 rotate relative to the support frame 19. The fourth sprocket 22 and its shafts rotate relative to the support frame 19. One of the rotating shafts 24 is fixedly connected, the conveyor belt 18 is sleeved on the rotating shaft 24, the third motor 20 is electrically connected to an external power supply, and the third motor 20 is signal connected to the control mechanism. The control mechanism controls the output end of the third motor 20 to rotate, thereby causing the third motor 20 to drive the third sprocket 21 to rotate, and the second chain 23 on the third sprocket 21 to drive the fourth sprocket 22 to rotate, thereby causing the fourth sprocket 22 to drive the rotating shaft 24 to rotate, so that the rotating shaft 24 can drive the conveyor belt 18 to rotate, and thus output the goods on the conveyor belt 18.

[0025] Specifically, the control mechanism includes a motor controller 25, a main controller 26, and a first infrared sensor 27. The motor controller 25 and the main controller 26 are both mounted on the frame 1, and the first infrared sensor 27 is mounted on the support frame 19. The conveyor belt 18 has a protrusion 28, which the first infrared sensor 27 senses. The motor controller 25 is signal-connected to the main controller 26 and to the second motor 12. The main controller 26 is connected to the first motor 3 and the third motor 12, respectively. The third motor 20 is connected to the first infrared sensor 27. When the conveyor belt 18 rotates, after the first infrared sensor 27 senses the position of the protrusion 28, it sends a signal to the main controller 26. The main controller 26 controls the third motor 20 to stop working immediately, so that the conveyor belt 18 stops moving. When the device needs to move forward or backward, the main controller 26 sends a control signal to the motor controller 25, so that the motor controller 25 controls the second motor 12 to rotate forward or backward, thereby realizing the forward or backward movement of the device.

[0026] Specifically, the control mechanism further includes a first limit switch 29 and a second limit switch 30. The first limit switch 29 can be a TZ-8107 model, and the second limit switch 30 can be a TZ-8108 model. The first limit switch 29 is disposed on the frame 1, and the second limit switch 30 is disposed at the end of the frame 1. During the upward movement, the second sprocket assembly 8 can contact the first limit switch 29 and send the signal generated during contact to the first motor 3 through the main controller 26. The second limit switch 30 sends a control signal to the motor controller 25 through the main controller 26, and then sends a control signal to the first motor 3 through the motor controller 25. The second limit switch on the frame 1 is controlled by the main controller 26. The control signal is sent to the motor controller 25, which in turn sends the control signal to the second motor 12. Due to the action of the first limit switch 29, when the lifting frame 2 rises to its highest height, one of the fifth sprockets on the second sprocket group 8 will contact the first limit switch 29. Therefore, the first limit switch 29 will send a signal to the main controller 26, which will then control the first motor 3 to stop working, thus stopping the conveying mechanism from rising further after reaching its highest position. When the second limit switch 30 touches an obstacle on the device's path, it will send a signal to the main controller 26, which will then control the second motor 12 to stop working, thereby stopping the device.

[0027] Specifically, the control mechanism further includes a second infrared sensor 31, a third infrared sensor 32, a fourth infrared sensor 33, a fifth infrared sensor 34, and a sixth infrared sensor 35. The second infrared sensor 31 is mounted on the lifting frame 2 and is used to sense the rising height of the lifting frame 2. The third infrared sensor 32, the fourth infrared sensor 33, and the fifth infrared sensor 34 are all located at the bottom of the frame 1. The third infrared sensor 32 is used to sense the forward or backward distance of the frame 1, the fourth infrared sensor 33 is used to sense the lowest descending position of the lifting frame 2, and the fifth infrared sensor 35... Sensor 34 is used to sense the distance between the frame 1 and obstacles during the forward movement. The sixth infrared sensor 35 is mounted on the frame 1 and is used to sense the height of the conveyor belt 18. The second infrared sensor 31, third infrared sensor 32, fourth infrared sensor 33, fifth infrared sensor 34, and sixth infrared sensor 35 are all signal-connected to the main controller 26. Through the function of the second infrared sensor 31, the rising height of the lifting frame 2 can be sensed, thereby enabling the second infrared sensor 31 to send control signals to the main controller 26. The main controller 26 stops the rising of the conveyor mechanism; through the function of the third infrared sensor 32, a control signal is sent to the main controller 26, which in turn sends a signal to the motor controller 25, and the motor controller 25 controls the second motor 12 to stop working, enabling the device to move to a designated position according to the set travel distance; through the function of the fourth infrared sensor 33, a control signal is sent to the main controller 26, which in turn sends a signal to the main controller 26. The signal is sent to the first motor 3, causing the output end of the first motor 3 to rotate in the opposite direction. Through the cooperation of the first motor 3, the first sprocket 4, the second sprocket 5, the first chain 6, the first sprocket group 7, and the second sprocket group 8, the conveying mechanism is adjusted to the lowest position. Through the function of the fifth infrared sensor 34, a control signal can be sent to the main controller 26. Therefore, the main controller 26 sends a signal to the motor controller 25, and the motor controller 25 controls the second motor 12 to stop moving. Then, the main controller 26 can control the conveying mechanism to output goods.Through the function of the sixth infrared sensor 35, a control signal can be sent to the main controller 26. The main controller 26 then sends a signal to the first motor 3 to start rotating forward. Through the cooperation of the first motor 3, the first sprocket 4, the second sprocket 5, the first chain 6, the first sprocket group 7, and the second sprocket group 8, the conveying mechanism is adjusted to the delivery height, thereby completing the output of goods.

[0028] Specifically, the frame 1 is also equipped with a storage battery 10, which is electrically connected to the motor controller 25, the main controller 26, the first motor 3, the second motor 12, the third motor 20, the first infrared sensor 27, the second infrared sensor 31, the third infrared sensor 32, the fourth infrared sensor 33, the fifth infrared sensor 34, and the sixth infrared sensor 35, the first limit switch 29, and the second limit switch 30. Through the function of the storage battery 10, power can be provided to this device, thereby ensuring the normal use of this device.

[0029] Specifically, it also includes a server (not shown), which is signal-connected to the main controller 26 and electrically connected to an external power supply. In addition, it can also be signal-connected to the server via a mobile terminal (not shown), which sends signals to the server and sends control signals to the main controller 26 via the server (not shown), thereby controlling the device to complete the picking and shipping operations via the main controller 26.
