Description

Technical Field

[0001] This utility model application relates to the field of chain machine technology, and in particular to a chain machine with hydraulic lifting function. Background Technology

[0002] With the rapid development of the modern logistics industry, four-way automated guided vehicle (AGV) systems are becoming increasingly common in various industries. Against the backdrop of the rapid development of the logistics and warehousing industry today, AAV systems have gained wider application due to their significant advantages such as high efficiency, flexibility, and high space utilization. This system enables rapid storage and retrieval of goods through the movement of four-way vehicles between automated racks, greatly improving the efficiency of warehousing operations. However, some existing AAV systems have deficiencies in certain functions, resulting in higher operating costs for users.

[0003] Regarding the aforementioned technologies, the inventors believe that existing four-way automated guided vehicle (AGV) conveyor systems, due to unreasonable conveyor line height settings, often require the use of specialized equipment such as forklifts when placing or removing goods from the conveyor line. This operation method not only increases the purchase and maintenance costs of equipment but also significantly increases labor costs and reduces the efficiency of goods transportation. Furthermore, frequent use of forklifts and other equipment for loading and unloading goods poses certain safety hazards and may damage goods and equipment. Therefore, a chain conveyor with hydraulic lifting function is proposed to solve the above problems.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the aforementioned problems, this application provides a chain machine with a hydraulic lifting function.

[0006] The chain machine with hydraulic lifting function provided in this utility model application adopts the following technical solution:

[0007] A chain machine with hydraulic lifting function includes a frame, inside which multiple hydraulic cylinders are arranged, and the multiple hydraulic cylinders share a lifting platform plate. Conveyor chain assemblies are installed on both outer walls of the lifting platform plate. A mounting frame is fixedly connected to the bottom outer wall of the lifting platform plate. A drive assembly for driving the two conveyor chain assemblies to rotate synchronously is fixedly installed on the inner wall of the mounting frame. Two side mounting plates are fixed to both outer walls of the lifting platform plate, and limit components are provided on both sides of the lifting platform plate.

[0008] Preferably, the drive assembly includes a motor, which is fixedly mounted on the outer wall of the mounting frame. A drive wheel is fixedly connected to the output end of the motor. Two support frames are fixedly connected to the outer walls on both sides of the mounting frame. The two support frames share a connecting shaft. A driven wheel is fixedly connected to the outer wall of the connecting shaft. An annular belt is provided between the driven wheel and the drive wheel. The annular belt meshes with the driven wheel and the drive wheel. Two transmission sprockets are fixedly connected to the outer walls on both sides of the connecting shaft.

[0009] Preferably, the limiting component includes a bracket, a long frame is fixedly connected to the outer wall of the bracket, a spring is fixedly connected to the outer wall of the long frame, and a guide rod is mounted on the long frame through the spring. A first connecting seat is fixedly connected to the outer wall of the guide rod, a first connecting rod is rotatably connected to the outer wall of the first connecting seat, a second connecting seat is fixedly connected to the outer wall of the long frame, and a second connecting frame is rotatably connected to the outer wall of the second connecting seat. The second connecting frame is hinged to the first connecting rod.

[0010] Preferably, the outer wall of the long frame is provided with a sliding groove, and a sliding seat is slidably connected to the outer wall of the sliding groove. A connecting rod is provided between the sliding seat and the guide rod, and the two ends of the connecting rod are hinged to the sliding seat and the guide rod.

[0011] Preferably, the outer wall of the bracket is fixedly connected with an installation block, and the two sides of the lifting platform plate are fixedly installed to the bracket through side installation plates.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. By using multiple hydraulic cylinders, the hydraulic system controls these cylinders to raise and lower the lifting platform. This allows the platform to connect with the rear conveyor belt at a specific height, while simultaneously lowering it to ground level at the manual docking end. The lifting platform is then coordinated with conveyor chain assemblies on both sides, driven by a drive unit to transport goods from the conveyor belt to the platform. Compared to existing technologies, this method allows for easy unloading of goods from a four-way vertical storage unit on a conveyor belt at a certain height. It also facilitates loading goods onto the conveyor belt, enabling forklift operations and significantly reducing labor and equipment purchase / maintenance costs for users, while improving the efficiency of goods transport.

[0014] 2. By setting limiting components on both sides of the lifting platform, the larger opening of the two guide rods is aligned with the outlet of the conveyor line. When unloading goods from the conveyor line, the two guide rods limit the movement of the goods onto the lifting platform, preventing them from falling and improving the stability of the goods transport, thus greatly enhancing the safety of the device.

[0022] The following is in conjunction with the appendix Figure 1 - Figure 6 This application will be described in further detail.

[0023] Example 1:

[0024] A chain conveyor with hydraulic lifting function includes a frame 1. Multiple hydraulic cylinders 9 are installed inside the frame 1, and these cylinders 9 are connected to a lifting platform 4. The lifting platform 4 facilitates the placement of goods. The output ends of the hydraulic cylinders 9 are fixedly connected to the four corners of the lifting platform 4. The hydraulic cylinders 9 are controlled by a hydraulic system. Upon receiving a command, the controller in the hydraulic system starts the hydraulic pump, and hydraulic oil enters the hydraulic cylinders 9 through hydraulic lines, pushing the pistons of the cylinders 9 to rise or fall, thereby lifting the lifting platform 4. Conveyor chains are installed on both outer walls of the lifting platform 4. The bottom outer wall of the lifting platform plate 4 is fixedly connected to the mounting frame 7. The inner wall of the mounting frame 7 is fixedly installed with a drive component that drives the two conveyor chain assemblies 2 to rotate synchronously. The drive component can drive the conveyor chain assemblies 2 on both sides to rotate synchronously, thereby enabling the conveyor chain assemblies 2 on both sides to transport the goods on the conveyor line to the lifting platform plate 4. Similarly, the goods on the lifting platform plate 4 can be transported to the conveyor line. Two side mounting plates 10 are fixed to the outer walls of both sides of the lifting platform plate 4, and limit components are provided on both sides of the lifting platform plate 4. The limit components facilitate the limiting of goods, thereby preventing the goods from falling during the transportation process and improving the safety of the device.

[0025] The drive assembly includes a motor 6, which is fixedly mounted on the outer wall of the mounting frame 7. A drive wheel 17 is fixedly connected to the output end of the motor 6. Two support frames 8 are fixedly connected to the outer walls of both sides of the mounting frame 7. A connecting shaft 21 is shared by the two support frames 8. A driven wheel 19 is fixedly connected to the outer wall of the connecting shaft 21, and an annular belt 18 is provided between the driven wheel 19 and the drive wheel 17. The annular belt 18 meshes with both the driven wheel 19 and the drive wheel 17. Two transmission sprockets 20 are fixedly connected to the outer walls of both sides of the connecting shaft 21. A transmission shaft is provided between the two conveyor chain assemblies 2, and both sides of the transmission shaft... Two sprocket bodies are installed. One of the sprocket bodies is connected to the drive sprocket 20 via a chain. The motor 6 is started by controlling the motor, which drives the drive wheel 17 to rotate. The drive wheel 17 drives the driven wheel 19 to rotate via the annular belt 18, thereby driving the connecting shaft 21. The connecting shaft 21 then drives the drive sprockets 20 on both sides synchronously. The drive sprockets 20 on both sides drive the drive shaft above to rotate synchronously via the chain. The sprockets on the drive shaft drive the conveyor chain to work, facilitating the movement of goods.

[0026] The limiting assembly includes a bracket 13, with a long frame 22 fixedly connected to the outer wall of the bracket 13. A spring member 16 is fixedly connected to the outer wall of the long frame 22, and a guide rod 28 is mounted on the long frame 22 via the spring member 16. The guide rod 28 has a larger opening on the side with the spring member 16 to facilitate the entry of goods. A first connecting seat 24 is fixedly connected to the outer wall of the guide rod 28, and a first connecting rod 23 is rotatably connected to the outer wall of the first connecting seat 24. A second connecting seat 26 is fixedly connected to the outer wall of the long frame 22, and a second connecting frame 25 is rotatably connected to the outer wall of the second connecting seat 26. The second connecting frame 25 is hinged to the first connecting rod 23, and the first connecting rod 23 connects to the second connecting frame. The hinge at 25 facilitates the stable installation of one end of the guide rod 28. When goods enter from the end with the larger opening of the guide rod 28, the two guide rods 28 limit the goods to prevent them from falling. At the same time, when the goods are transported to a certain position, the goods apply pressure to the spring 16 through the guide rod 28, thereby compressing the spring 16 and bringing the two ends of the guide rod 28 into a balanced state, thus limiting the goods with the two guide rods 28. When the operator removes the goods with a forklift, the spring 16 releases its elastic potential energy, causing the guide rod 28 to rebound and return to its original position, facilitating the entry of the next goods.

[0027] The outer wall of the long frame 22 is provided with a sliding groove 14, and a sliding seat 15 is slidably connected to the outer wall of the sliding groove 14. A connecting rod 27 is provided between the sliding seat 15 and the guide rod 28, and the two ends of the connecting rod 27 are hinged to the sliding seat 15 and the guide rod 28. Through the cooperation of the connecting rod 27, the sliding seat 15 and the sliding groove 14, the stability of the end of the guide rod 28 where the spring member 16 is installed is improved, and the guide rod 28 is prevented from swaying back and forth.

[0028] The outer wall of the bracket 13 is fixedly connected with the mounting block 12, and the two sides of the lifting platform plate 4 are fixedly installed with the bracket 13 through the side mounting plate 10. By connecting the mounting block 12 with the mounting hole on the side mounting plate 10, the bracket 13 is fixed on the side mounting plate 10 by bolts, thus completing the installation of the limit component.

[0029] The implementation principle of a chain machine with hydraulic lifting function according to an embodiment of this utility model is as follows: The operator first moves the device to the output position of the four-way garage conveyor line for alignment. When the goods arrive at the unloading position, the hydraulic system controls multiple hydraulic cylinders 9 to rise, causing the output ends of the cylinders 9 to lift the lifting platform plate 4, aligning it with the conveyor line. Simultaneously, the controller starts the motor 6, causing the output shaft of the motor 6 to drive the drive wheel 17 to rotate. The drive wheel 17 then drives the driven wheel 19 to rotate synchronously via the annular belt 18, ensuring that the driven wheel 19 rotates synchronously. The driving wheel 19 drives the rotation of the connecting shaft 21, and the driven wheels 19 on both sides of the connecting shaft 21 are connected to the sprockets on the drive shaft inside the upper conveyor chain assembly 2 via chains, thereby realizing the transmission drive of the conveyor chain assemblies 2 on both sides of the lifting platform plate 4. The two conveyor chain assemblies 2 transport the goods on the conveyor line to the lifting platform plate 4. Then, the hydraulic system controls multiple hydraulic cylinders 9 to lower the lifting platform plate 4, so that the lifting platform plate 4 carries the goods down to be parallel to the ground, which is convenient for operators to unload the goods with a forklift. Similarly, it can also be loaded, which greatly facilitates the convenience of operation.

[0030] When goods move onto the lifting platform 4, the limiting components on both sides of the lifting platform 4, and the guide rods 28 of the limiting components, ensure that the diameter of the inlet between the two guide rods 28 is larger than the diameter of the outlet, thus facilitating the entry of goods. When the goods are transported to a certain position, the goods apply pressure to the section of the guide rod 28 with the spring 16, causing the inlet position of the guide rod 28 to return to its original position, and then the other end of the guide rod 28 to return to its original position simultaneously. This allows the two guide rods 28 to limit the goods being transported onto the lifting platform 4, preventing them from falling. At the same time, when the goods are unloaded by the forklift, the elastic potential energy of the spring 16 drives the guide rods 28 to return to their original position, thus facilitating the entry of goods the next time. The two guide rods 28 limit the movement of goods onto the lifting platform 4, preventing them from falling, improving the stability of goods transportation, and greatly enhancing the safety of the device.
