Description

Technical Field

[0001] The invention belongs to the technical field of stackers, and in particular relates to a lifting mechanism of a high-load stacker. Background Art

[0002] Stacking cranes, also known as stackers, are the most important lifting and transportation equipment in a three-dimensional warehouse and are the symbol of the characteristics of a three-dimensional warehouse. The main function of a stacking crane is to run back and forth in the aisles of a three-dimensional warehouse, storing the goods at the entrance of the aisle into the cargo compartment of the shelf, or taking out the goods in the cargo compartment and transporting them to the entrance of the aisle.

[0003] In the early days, stackers were built by hanging a gantry (column) on the trolley of a bridge crane, and using the up and down movement of the fork on the column and the rotation of the column to transport goods. They were usually called bridge stackers. Around 1960, aisle stackers appeared in the United States. This type of stacker uses ground rails to prevent tipping. Later, with the development of computer control technology and automated warehouses, stackers have become more and more widely used, with better technical performance and higher heights. Today, the height of a stacker can reach 40 meters. In fact, if it is not limited by warehouse construction and costs, the height of a stacker can be even higher. Summary of the invention

[0004] The purpose of the present invention is to provide a high-load stacker to solve the shortcomings of traditional stackers such as insufficient load, unstable transmission speed and insufficient transmission accuracy. By improving the coordinated control of the motor and the transverse motor, optimizing the gear and chain transmission, and real-time monitoring and intelligent control of sensors and other innovative features, the handling accuracy, efficiency and carrying capacity of the stacker are significantly improved, the energy consumption and operating costs are effectively reduced, and the safety and reliability of the system are enhanced.

[0006] Preferably, the lifting device is directly connected to the motor, and the gear and chain on the transmission shaft are used to lift the left side of the cargo platform. The gear arranged below the transmission shaft passes through the bottom of the cargo platform and is connected to the gear on the lower right side through a chain to lift the right side of the cargo platform.

[0007] Preferably, the transverse motor of the lifting device is installed relative to the lifting motor, a bevel gear is provided at the bottom of the transverse motor, and a second transmission shaft is provided in the middle. The transverse motor and the lifting motor are installed relative to each other, which can realize the coordinated control of the two movements. The lifting motor is responsible for the lifting movement in the vertical direction, while the transverse motor is responsible for the movement or positioning in the horizontal direction. The two cooperate with each other to realize more complex and precise motion control. Compared with spur gears, helical gears have a greater overlap and can withstand greater loads, making the transmission process smoother and less noisy. At the same time, the gradual meshing characteristics of the helical gears can reduce the impact between the gear teeth, further improving the smoothness and reliability of the transmission. A second transmission shaft is provided in the middle, which can effectively transmit and distribute power, transmit the power of the transverse motor to other transmission components, realize more complex motion control and power distribution, enable the lifting device to adapt to different working conditions and load requirements, and improve the stability and efficiency of the overall system.

[0008] Preferably, the gears of the lifting device are all mounted on shafts and each shaft is provided with a plurality of positioning components to position the gears.

[0009] Preferably, the first transmission part of the cargo platform is provided with a helical gear meshing with the helical rack of the cargo platform, and a plurality of hubs are provided on both sides of the first transmission part, and vertical small hubs are provided at the hubs at both ends to change the speed.

[0010] Preferably, a rectangular strip is provided in the middle of the second transmission part of the cargo platform, a plurality of wheel hubs are provided on the strip, and gears and chains are provided on both sides of the rectangular strip to drive the second transmission part.

[0011] Preferably, the third transmission part of the cargo platform has an outer shape of a cross-shaped frame, a groove is provided at the bottom thereof to be connected to the hub of the second transmission part, and hubs are provided on both sides to be locked in the grooves of the second transmission part.

[0012] Preferably, a motor drive is provided at the bottom of the cargo platform, which can realize precise control and efficient transmission, improve handling efficiency and capacity, reduce energy consumption and operating costs, and improve system reliability and safety.

[0013] Preferably, several sensors are arranged in the T-shaped boxes on both sides of the cargo platform and on the cargo platform to detect the operation status of the cargo platform, and a through hole for the chain to pass through is arranged in the middle of the T-shaped box.

[0014] Preferably, the cargo platform and the lifting device are mounted between the ceiling rail and the ground rail, and a gear bar is provided on the ground rail to mesh with a helical gear provided on the transverse motor.

[0015] The beneficial effect of the present invention is that the cooperative work of the lifting motor and the horizontal motor enables the stacker to not only efficiently lift goods in the vertical direction, but also to achieve rapid movement or precise positioning in the horizontal direction. Compared with the single vertical lifting or horizontal movement mode of the traditional stacker, this cooperative control greatly improves the efficiency of cargo handling and shortens the operation cycle, especially in situations where the position of goods needs to be frequently changed or multi-layer cargo is stacked, the advantages are more obvious.

[0016] The gear and chain transmission method has greater lifting force and higher transmission efficiency than the belt or hydraulic transmission that traditional palletizers may use. The gear transmission can ensure that the cargo platform is lifted to the required height smoothly and accurately. At the same time, the wear resistance and reliability of the chain also enable the palletizer to maintain stable performance during long-term and high-frequency operations, thereby improving the overall handling efficiency and carrying capacity.

[0017] The combination of motor drive and sensor detection enables the palletizer to monitor and precisely control the movement status of the cargo platform in real time. This means that the palletizer can effectively reduce ineffective movement during operation, such as avoiding excessive lifting or movement, thereby reducing energy consumption. At the same time, precise control also helps to reduce equipment loss caused by improper operation, extend equipment service life, and reduce maintenance costs.

[0018] The sensors installed in the T-shaped boxes on both sides of the cargo platform and on the cargo platform can monitor the operation status of the cargo platform in real time, such as key parameters such as position, speed, and load. Once an abnormal situation is detected, such as cargo tilting, overloading, etc., the system can promptly issue an alarm and take corresponding safety measures, such as stopping operation or adjusting the movement status, thereby effectively avoiding the occurrence of safety accidents and improving the safety of the palletizer.

[0019] The design of the third transmission part of the cross-shaped frame and the connection between the transmission parts through the hub and the groove enhance the structural stability of the cargo platform. This stability enables the stacker to remain stable when carrying heavy objects or operating on uneven ground, reducing cargo damage or equipment failure caused by vibration or impact, and improving the reliability of the system.

[0020] The combination of sensor detection and intelligent control system enables the palletizer to automatically adjust operating parameters such as speed and acceleration according to real-time monitoring data to adapt to different working environments and task requirements. This intelligent adaptability reduces the reliance on manual operation, improves the flexibility and response speed of the palletizer, and makes it more advantageous in the changing logistics needs between machine tools and various storage stations.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] A lifting mechanism of a high-load stacker includes a cargo platform and a lifting device. The lifting device is arranged on the left side of the cargo platform. The lifting device includes a lifting motor 9 and a transverse motor 10. A first transmission shaft is connected to the lifting motor 9. A plurality of gears 6 are arranged on the transmission shaft. The gears 6 are meshed and connected through a chain 7. The cargo platform is divided into a first transmission part 1, a second transmission part 2 and a third transmission part 3. Each transmission part is directly connected through a wheel hub and a groove. A plurality of wheel hubs are arranged on both sides of the cargo platform to contact the lifting device.

[0027] The lifting support frame mechanism design of this high-load stacker makes the overall structural layout reasonable by setting the lifting device on the left side of the cargo platform, which is conducive to the efficient lifting of the cargo platform. The lifting device includes a lifting motor 9 and a transverse motor 10, wherein the first transmission shaft is connected to the lifting motor 9, and a plurality of gears 6 are arranged on the transmission shaft, and the gears 6 are meshed and connected through chains 7. This transmission method can transmit the power of the lifting motor 9 to the gears 6 on the transmission shaft through the chain 7, and then the gears 6 drive the cargo platform to lift or lower. Since the chain 7 transmission has a high transmission efficiency and a large load-bearing capacity, it can realize the rapid and smooth lifting of the cargo platform, meet the requirements of the high-load stacker for lifting speed and stability, and thus improve the working efficiency of the stacker.

[0028] The cooperation between the wheel hub and the groove can tightly connect the various transmission parts together to form a whole, which enhances the rigidity and load-bearing capacity of the cargo platform. Several wheel hubs are arranged on both sides of the cargo platform to contact the lifting device. This design makes the cooperation between the cargo platform and the lifting device closer, which is conducive to more effectively transmitting the power of the lifting device to the cargo platform. At the same time, the contact between the wheel hub and the lifting device can also play a certain guiding role, ensuring that the cargo platform runs smoothly along the predetermined track during the lifting process, avoiding damage to the goods or failure of the stacker due to deviation or vibration.

[0029] Since the cargo platform is divided into multiple transmission parts, and each transmission part is connected through a hub and a groove, the structure and layout of each transmission part can be adjusted according to actual needs to adapt to different scenarios and load requirements. For example, when it is necessary to carry heavier goods, the number of transmission parts can be increased or the structure of the transmission part can be adjusted to improve the carrying capacity of the cargo platform; when it is necessary to increase the lifting speed, the connection method between the transmission parts can be optimized to reduce friction and loss during the transmission process. This flexible adaptability enables the stacker crane to better meet the needs of different users and has broad application prospects.

[0030] Since key components such as transmission components and motors are located in easy-to-maintain locations and the structure is reasonably designed, maintenance personnel can easily inspect, replace or repair these components.

[0031] The lifting device is directly connected to the motor. The gear 6 and chain 7 on the transmission shaft are used to lift the left side of the cargo platform. The gear 6 arranged below the transmission shaft passes through the bottom of the cargo platform and is connected to the gear 6 on the lower right side through the chain 7 to lift the right side of the cargo platform.

[0032] The power generated by the motor does not need to go through a complex conversion or transmission process, but directly acts on the drive shaft, minimizing energy loss. This direct connection method allows each torque output of the motor to be quickly converted into the rotational motion of the drive shaft, thereby quickly driving the cargo platform to rise or fall. Therefore, the cargo platform has a faster response speed and can complete the cargo handling task in a shorter time, significantly improving the working efficiency of the stacker crane, especially suitable for working between equipment and storage stations under heavy load and high precision environment requirements.

[0033] The gear 6 and chain 7 on the transmission shaft are used to lift the left side of the cargo platform. This design allows the lifting action on the left side of the cargo platform to be performed accurately according to the transmission ratio of the gear 6 and chain 7. The meshing transmission of the gear 6 and chain 7 has high transmission accuracy and stability, which can ensure that the left side of the cargo platform maintains a stable upward trajectory during the lifting process. At the same time, the flexibility of the chain 7 also enables the transmission system to adapt to certain load changes and impacts, avoiding transmission interruptions or damage caused by sudden placement of heavy objects or uneven distribution of cargo. In addition, the chain 7 transmission also has good self-lubricating properties, which can reduce friction and wear during the transmission process to a certain extent and extend the service life of the transmission system.

[0034] The gear 6 arranged below the transmission shaft passes through the bottom of the cargo platform and is connected to the gear 6 on the lower right side by a chain 7 to lift the right side of the cargo platform. This design realizes the synchronous lifting of the left and right sides of the cargo platform. When the gear 6 below the transmission shaft rotates, the gear 6 at the bottom of the cargo platform is driven to rotate synchronously through the transmission action of the chain 7, so that the right side of the cargo platform can also be lifted synchronously with the left side. This synchronous lifting mechanism is crucial to maintaining the horizontal balance of the cargo platform, especially when carrying goods with a high center of gravity or irregular shapes. It can effectively prevent the goods from sliding or tipping over due to the tilt of the cargo platform, ensuring the safe handling of the goods. At the same time, synchronous lifting also helps to reduce the vibration and impact generated by the cargo platform during the lifting process, improves the operating stability of the stacker, and provides a strong guarantee for the stable handling of goods.

[0035] The transverse motor 10 of the lifting device is installed opposite to the lifting motor 9. A bevel gear 8 is arranged at the bottom of the transverse motor 10, and a second transmission shaft is arranged in the middle.

[0036] By installing the transverse motor 10 of the lifting device opposite to the lifting motor 9, the coordinated control of the two movements can be achieved. The lifting motor 9 is mainly responsible for the lifting movement in the vertical direction, while the transverse motor 10 is responsible for the movement or positioning in the horizontal direction. This relative installation method allows the two to cooperate with each other during work to achieve more complex and precise motion control. For example, when transporting goods, the lifting motor 9 can lift the goods to a certain height, while the transverse motor 10 can move the goods to a specified position, thereby achieving precise positioning and transportation of the goods. This coordinated control not only improves the working efficiency of the stacker, but also can meet more complex transportation needs, such as the storage and retrieval of goods on multi-layer shelves.

[0037] A bevel gear 8 is arranged at the bottom of the transverse motor 10. Compared with the traditional spur gear, the bevel gear 8 has a greater overlap. The overlap refers to the ratio of the number of teeth that are simultaneously engaged when the gears are meshing. The overlap of the bevel gear 8 is usually greater than that of the spur gear. This means that during the transmission process, more teeth will be engaged at the same time, making the transmission smoother and able to withstand greater loads. This is especially important for the lifting device, because the lifting device needs to withstand a large load, and the high overlap of the bevel gear 8 can effectively disperse the load, reduce the force on a single tooth, and improve the service life and reliability of the gear. At the same time, the gradual meshing characteristics of the bevel gear 8 can also reduce the impact between the gear teeth, reduce the noise during the transmission process, and make the operation of the lifting device quieter and more stable.

[0038] The benefit of having a second transmission shaft in the middle is that it can effectively transmit and distribute power. The second transmission shaft can transmit the power of the transverse motor 10 to other transmission components, such as other parts of the lifting device or other transmission mechanisms of the cargo platform. This design can achieve more complex motion control and power distribution, so that the lifting device can adapt to different working conditions and load requirements. For example, when lifting and moving operations are required at the same time, the second transmission shaft can distribute the power of the transverse motor 10 to other parts of the lifting device to achieve synchronous lifting and movement. In addition, the second transmission shaft can also increase the flexibility of the transmission system, making the design of the lifting device more compact and efficient, and improving the stability and efficiency of the overall system. This design can also simplify the structure of the transmission system and reduce the number of transmission components, thereby reducing manufacturing and maintenance costs.

[0039] The gears of the lifting device are all mounted on the shafts and each shaft is provided with a plurality of positioning components to position the gears 6 .

[0040] The gears 6 of the lifting device are all mounted on the shaft and each shaft is provided with several positioning components to position the gears 6. This design significantly improves the transmission accuracy and stability. The positioning component ensures the accurate position of the gear 6 on the shaft and prevents it from axial or radial displacement during operation, thereby ensuring that the meshing between the gears 6 and the gears 6 is more accurate and reducing the transmission error. At the same time, the positioning component can also withstand the axial force and radial force generated by the gear 6 during operation, disperse the force of the gear 6, enhance the bearing capacity of the gear 6 and the shaft, and enable the lifting device to withstand a larger load. In addition, stable operation reduces the friction and impact between the gear 6 and the shaft, and prolongs the service life of the gear 6 and the shaft. In terms of installation and maintenance, the setting of the positioning component simplifies the installation process, making the installation of the gear 6 more convenient and quick, and also facilitates maintenance and replacement, reducing maintenance costs. More importantly, the positioning component can effectively prevent the gear 6 from falling off or being damaged due to unexpected circumstances during operation, improve the reliability and safety of the system, and ensure the long-term stable operation of the lifting device and the efficient operation of the stacker.

[0041] The first transmission part 1 of the cargo platform is provided with a helical gear 8 meshing with the helical rack of the cargo platform. A plurality of hubs are provided on both sides of the first transmission part 1, and vertical small hubs 5 are provided at the hubs at both ends to change the speed.

[0042] The first transmission part 1 of the cargo platform is provided with a helical gear 8 meshing with the helical rack of the cargo platform. This design can firstly significantly improve the transmission efficiency and stability. The meshing transmission of the helical gear 8 and the helical rack has a high stability, because the tooth surface of the helical gear 8 and the tooth surface of the rack are gradually in contact and gradually withdrawn. This gradual meshing method makes the transmission process more stable, reduces impact and vibration, and thus improves the stability of the transmission. This is very important for the cargo platform to maintain stable operation during the handling process, especially when carrying heavier or larger-sized goods, it can effectively avoid the tilting or overturning of the goods caused by the unstable transmission, and ensure the safe handling of the goods. In addition, the overlap of the helical gear 8 transmission is large, which means that during the transmission process, more teeth will participate in the meshing at the same time. This not only improves the stability of the transmission, but also can withstand a larger load, enhances the carrying capacity of the transmission system, and enables the cargo platform to adapt to higher load requirements and meet the use requirements of high-load stackers.

[0043] In terms of precise motion control, the cooperation between the bevel gear 8 and the bevel rack can accurately convert rotary motion into linear motion, or convert linear motion into rotary motion. This precise motion conversion is very important for the precise positioning and handling of the cargo platform, and can ensure that the goods are accurately placed at the designated location. For example, when performing storage and retrieval operations of goods, the cargo platform needs to be accurately moved to a specific position on the shelf. The transmission of the bevel gear 8 and the bevel rack can provide precise motion control, so that the cargo platform can quickly and accurately reach the target position, thereby improving the efficiency and accuracy of cargo handling. At the same time, since the meshing transmission of the bevel gear 8 and the bevel rack has a high transmission accuracy, the transmission error can be reduced, thereby improving the positioning accuracy of the cargo platform. This is particularly important for occasions that require high-precision handling, such as in automated warehouses, where the storage and retrieval positions of goods need to be very precise to avoid damage or loss of goods and ensure efficient operation of the warehouse.

[0044] Several hubs are arranged on both sides of the first transmission part 1 of the cargo platform, and vertical small hubs 5 are arranged at the hubs at both ends to change their speed. This design allows the cargo platform to flexibly adjust the movement speed as needed. For example, when carrying heavier or lighter goods, the transmission ratio can be changed by adjusting the small hub 5, so as to adjust the running speed of the cargo platform to adapt to different handling requirements. This speed adjustment function provides greater flexibility for the cargo platform, enabling it to better adapt to different working conditions and task requirements. For example, when a large amount of goods needs to be transported quickly, the speed can be increased to shorten the handling time and improve work efficiency; and when the goods need to be placed accurately, the speed can be reduced to ensure the stability and accuracy of the handling and avoid damage to the goods or position deviation caused by excessive speed. In addition, this speed adjustment function can also be optimized according to the actual handling distance and the characteristics of the goods, making the operation of the cargo platform more efficient and economical.

[0045] In terms of structural design, the transmission structure of the helical gear 8 and the helical rack is relatively compact, takes up little space, and is conducive to the overall design and layout of the cargo platform. The compact structural design can make the cargo platform lighter and reduce its own weight, thereby improving its carrying capacity and flexibility. At the same time, the arrangement of the hub and the small hub 5 also makes the transmission system more compact, improves the space utilization rate, and enables the cargo platform to achieve more functions and higher efficiency in a limited space. In addition, the compact structural design also helps to reduce manufacturing costs and maintenance costs, because the number and complexity of transmission components are reduced, making the production and maintenance of the cargo platform simpler and more economical. Convenient maintenance is another important advantage of this design. Since the meshing transmission structure of the helical gear 8 and the helical rack is relatively simple, maintenance and replacement are relatively easy. When it is necessary to maintain the transmission system, it is convenient to check and replace components such as gears and racks, reducing maintenance costs and time. For example, when the helical gear 8 or the helical rack is worn or damaged, the maintenance personnel can quickly find the fault location and replace or adjust it to ensure the normal operation of the cargo platform.

[0046] A rectangular strip is arranged in the middle of the second transmission part 2 of the cargo platform, on which a plurality of hubs are arranged, and gears and chains 7 are arranged on both sides of the rectangular strip to drive the second transmission part 2 .

[0047] A rectangular strip is arranged in the middle of the second transmission part 2 of the cargo platform, and this design provides a stable structural foundation for the transmission part. Compared with structures of other shapes, the square strip has stronger torsion resistance and load-bearing capacity, and can effectively support and fix the wheel hub and other transmission parts above. When the cargo platform is carrying goods, the square strip can withstand the weight of the goods and various forces during the movement, and maintain the stability and reliability of the transmission part. At the same time, the design of the square strip is also conducive to improving the rigidity of the transmission part, reducing deformation during heavy load or high-speed movement, and ensuring the accuracy and consistency of the transmission process. In addition, the square strip can also serve as the skeleton of the transmission part, and work in coordination with other transmission parts such as gears, chains 7, etc. to form a complete transmission system, so as to realize efficient motion control of the cargo platform.

[0048] Several wheel hubs are arranged on the rectangular strips, which are closely integrated with the rectangular strips and jointly undertake the movement task of the cargo platform. The arrangement of the wheel hubs can realize the rotation or movement of the cargo platform, providing a flexible mode of movement for the cargo platform. For example, when carrying goods, the wheel hubs can drive the cargo platform to rotate to adapt to different carrying directions and angles, thereby improving the flexibility and efficiency of the transportation. At the same time, the wheel hubs can also contact the ground or other supporting structures to provide additional support and guidance, thereby ensuring the stability and accuracy of the cargo platform during the movement. In addition, the design of the wheel hubs is also conducive to reducing friction and wear, and improving the service life and reliability of the transmission system.

[0049] Gears and chains 7 are provided on both sides of the rectangular strip to drive the second transmission part 2. This transmission combination of gears and chains 7 has significant advantages. First, the gear transmission has high transmission accuracy and stability, can accurately transmit power, and ensure the movement accuracy and consistency of the cargo platform. The meshing transmission of the gears can also withstand larger loads, enhance the carrying capacity of the transmission system, and enable the cargo platform to adapt to heavier cargo handling needs. Secondly, the chain 7 transmission has good self-lubricating properties and a low friction coefficient, and can maintain stable transmission efficiency under various working conditions and reduce energy losses. The flexibility of the chain 7 also enables the transmission system to adapt to certain load changes and impacts, avoiding transmission interruptions or damage caused by sudden placement of heavy objects or uneven distribution of cargo.

[0050] The third transmission part 3 of the cargo platform has a cross-shaped frame shape, a groove is set at the bottom thereof to be connected with the hub of the second transmission part 2, and hubs are set on both sides to be locked in the grooves of the second transmission part 2, and a motor drive is set at the bottom of the cargo platform. Several sensors 4 are set on both sides of the cargo platform and on the cargo platform to detect the operating status of the cargo platform, and several sensors are set in the T-shaped boxes 12 on both sides of the cargo platform and on the cargo platform to detect the operating status of the cargo platform. A through hole is set in the middle of the T-shaped box 12 for the chain to pass through. The cargo platform and the lifting device are mounted on the ceiling rail and the ground rail, and there are gears on the ground rail that mesh with the bevel gear 8 set on the transverse motor 10.

[0051] The third transmission part 3 of the cargo platform adopts a cross-shaped frame structure. This design can firstly significantly improve the stability and load-bearing capacity of the structure. Compared with frames of other shapes, the cross-shaped frame has better rigidity and torsion resistance, which enables it to effectively withstand the weight of the cargo and various forces during the movement when the cargo platform is carrying cargo, and maintain the stability and reliability of the transmission part. In addition, the design of the cross-shaped frame also enables the load of the cargo platform to be more evenly distributed in various parts of the frame, avoiding local overload, thereby improving the load-bearing capacity of the transmission part, allowing the cargo platform to adapt to the needs of heavier cargo handling and meet the use requirements of high-load stackers.

[0052] In terms of motion control and transmission efficiency, a groove is provided at the bottom of the third transmission part 3 to connect with the hub of the second transmission part 2. This precise connection method can ensure the coordinated movement between the two transmission parts. The cooperation between the groove and the hub can achieve smooth transmission, reduce friction and wear during movement, and improve transmission efficiency. At the same time, hubs are provided on both sides to lock in the grooves of the second transmission part 2. This design enables the third transmission part 3 to be motion controlled in multiple directions. The setting of the hub lock can realize the rotation or movement of the cargo platform, providing a flexible movement mode for the cargo platform, enabling it to adapt to different handling tasks and working environments more flexibly, and improving the efficiency and flexibility of handling.

[0053] A motor drive is provided at the bottom of the cargo platform. This design makes the movement of the cargo platform more precise and controllable. The motor drive can adjust the movement speed and direction as needed to achieve precise positioning and handling of the cargo platform, thereby improving work efficiency and handling accuracy. For example, when performing storage and retrieval operations on goods, the motor drive can accurately control the cargo platform to move to a specific position on the shelf to ensure that the goods are accurately placed or taken out. In addition, a number of sensors 4 are provided on both sides of the cargo platform and on the cargo platform. These sensors 4 can monitor the operating status of the cargo platform in real time, such as position, speed, load and other information. Through the detection of the sensor 4, potential faults and anomalies can be discovered and handled in a timely manner, ensuring the safe and stable operation of the cargo platform, avoiding damage to goods or handling errors caused by faults, and improving the reliability and safety of the system.

[0054] The cargo platform and the lifting device are set up in the ceiling rail and the ground rail. This design provides a stable running track for the cargo platform. The cooperation of the ceiling rail and the ground rail can limit the range of motion of the cargo platform, avoid damage to the goods or handling errors caused by deviation or vibration, and ensure the smooth operation of the cargo platform during the handling process. There is a gear bar on the ground rail that meshes with the bevel gear 8 set by the transverse motor 10. This transmission method can achieve smooth movement and precise positioning of the cargo platform. The meshing transmission of the bevel gear 8 has high transmission accuracy and stability, which can reduce transmission errors and improve the operation efficiency and reliability of the cargo platform. In addition, the meshing of the gear bar and the bevel gear 8 can also provide a large driving force, so that the cargo platform can carry heavier goods and move smoothly on the ground rail to meet the handling needs of high-load stackers.
