Description

Technical Field

[0001] This utility model relates to the field of warehousing and logistics equipment technology, and in particular to a lifting chain machine for AGV connection. Background Technology

[0002] Warehousing and logistics are core components of the modern supply chain system. Through the organic integration of specialized warehousing facilities and intelligent logistics networks, they enable the efficient flow of goods from production to consumption. Their core functions encompass cargo storage, sorting and packaging, transportation and distribution, and information management. Relying on automated warehousing systems, IoT technology, and big data analytics, they precisely control inventory and optimize delivery routes, ensuring the safety of goods in warehousing and the timeliness of logistics. Modern warehousing and logistics not only provides standardized warehousing services but also extends to diversified scenarios such as supply chain finance, cross-border logistics, and cold chain transportation, significantly improving supply chain responsiveness and resource utilization.

[0003] In warehousing and logistics systems, the efficient connection between AGVs and conveying equipment is a key link in achieving automated flow. Traditional chain conveyors typically have their drive mechanisms (such as geared motors and drive shafts) installed at the bottom. First, the mechanical structure at the bottom of the equipment forces an increase in the equipment's height off the ground. This requires a certain height, necessitating the excavation of deep pits or the raising of the connection platform to meet the passage requirements of AGVs or manual forklifts, significantly increasing civil engineering and modification costs. Second, the lateral space occupies a significant amount of space, and the protruding parts of the drive components are prone to interference with adjacent conveyor lines, limiting the compact layout.

[0004] Therefore, it is necessary to provide a lifting chain machine for AGV docking to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a lifting chain machine for AGV docking, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: A lifting chain machine for AGV docking includes a column frame, a lifting reduction motor fixed at the top of the column frame, support seats fixed at both the top and bottom of the column frame, and a transmission shaft rotatably connected within the support seats. Multiple sprockets are fixed on the side of the transmission shaft, and two sets of lifting chains a and b are meshed on the sprockets. A bracket is provided at the bottom of the column frame, and the two sets of lifting chains a and b are symmetrically distributed on both sides of the bracket. The bracket is lifted and moved by pulling the two sets of lifting chains a and b.

[0007] As a further embodiment of this utility model, a conveyor chain machine is installed on the bracket, and lifting arms are fixed on both sides of the bracket. The two ends of the lifting chain a and the lifting chain b are respectively fixed to the top and bottom ends of the bracket, and guide rails arranged along the height direction of the column are fixed on the column of the column frame.

[0008] As a further embodiment of this utility model, the lifting arm is equipped with a retaining wheel and a guide wheel, which are in rolling contact with the guide rail.

[0009] As a further embodiment of this utility model, a coupling is provided at the end of the transmission shaft, and the output end of the lifting and decelerating motor is connected to the transmission shaft through the coupling.

[0010] As a further embodiment of this utility model, adjusting screws are provided at the connection points between the ends of the lifting chains a and b and the bracket.

[0011] As a further embodiment of this utility model, the bottom of the column frame is fixed with multiple support legs, and the multiple support legs are symmetrically distributed.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The output of the lifting reduction motor drives the drive shaft to rotate, which in turn drives multiple sprockets. These sprockets and the drive shaft work together to simultaneously drive the closed-loop lifting chains a and b on both sides, ensuring synchronous lifting. Lifting chains a and b then forcefully pull and lift the pallet for connection. By mounting the lifting reduction motor and drive shaft above the column frame, the footprint of the reducer and drive shaft in existing technologies is effectively reduced, improving space utilization. This also prevents interference between the reducer and the connecting conveyor equipment. Since the drive shaft does not need to be installed under roller conveyors or other conveying equipment, the pallet landing distance is lower, facilitating manual pallet forklift connection. The equipment can be installed without digging a pit or with a shallow pit, effectively reducing investment and subsequent maintenance costs. Attached Figure Description

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figure 1-4 This utility model provides a lifting chain machine for AGV docking, including a column frame 3. A lifting reduction motor 1 is fixed on the top of the column frame 3. Support seats are fixed on both the top and bottom of the column frame 3, and a transmission shaft 12 is rotatably connected inside the support seats. Multiple sprockets 13 are fixed on the side of the transmission shaft 12. Two sets of lifting chains a8 and b9 are meshed on the sprockets 13. A bracket 6 is provided at the bottom of the column frame 3. The two sets of lifting chains a8 and b9 are symmetrically distributed on both sides of the bracket 6. The bracket 6 is lifted and moved by pulling the two sets of lifting chains a8 and b9. In specific operation, the output end of the lifting reduction motor 1 drives the transmission shaft 12 to rotate, thereby driving the multiple sprockets 13. The rotation of the sprocket 13 and drive shaft 12 drives the closed-loop lifting chains a8 and b9 on both sides simultaneously, ensuring synchronous lifting. The lifting chains a8 and b9 then forcefully pull and lift the bracket 6 for connection. The lifting reduction motor 1 and drive shaft are installed above the column frame 3, effectively reducing the footprint of the reducer and its drive shaft in the prior art, effectively improving space utilization, and preventing interference between the reducer and the connecting conveyor equipment. Since the drive shaft does not need to be installed under the roller conveyor or other conveying equipment, the pallet landing distance is lower, facilitating manual pallet forklift docking. The equipment can be installed without digging a pit or with a shallow pit, effectively reducing investment and subsequent maintenance costs.

[0023] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that a conveyor chain machine 7 is installed on the bracket 6. Lifting arms 4 are fixed on both sides of the bracket 6. The two ends of lifting chains a8 and b9 are fixed to the top and bottom of the bracket 6, respectively. Guide rails arranged along the height of the column are fixed on the column of the column frame 3. The lifting arms 4 are equipped with rollers 5 and guide wheels 10, which are in rolling contact with the guide rails. In actual operation, the lifting arms are installed on both sides of the bracket, and the conveyor chain machine 7 is installed on the bracket 6. The lifting arms 4, rollers 5 and guide wheels 10 work together to ensure that the bracket 6 moves in a straight line, improving the stability of the lifting and moving of the bracket 6, so that the items carried on the conveyor chain machine 7 do not tilt or overturn.

[0024] Further as Figure 2 As shown, it is worth noting that a coupling 2 is provided at the end of the drive shaft 12, and the output end of the lifting reduction motor 1 is connected to the drive shaft 12 through the coupling 2. The coupling 2 ensures stable power transmission, adapts to the alignment error between shafts, reduces stress concentration and wear caused by inaccurate installation or thermal deformation, and effectively compensates for deviations.

[0025] Further as Figure 3 As shown, it is worth noting that adjusting screws 11 are provided at the connection points between the ends of lifting chains a8 and b9 and the bracket 6; the tension of the chains can be precisely adjusted by adjusting screws 11 to avoid slippage, skipping teeth, or increased wear caused by the chains being too loose.

[0026] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the bottom of the column frame 3 is fixed with multiple support legs, and the multiple support legs are symmetrically distributed.

[0027] In summary: The bracket 6 is forcibly pulled and lifted by lifting chains a8 and b9 for connection; the lifting reduction motor 1 and drive shaft are installed above the column frame 3, which effectively reduces the footprint of the reducer and its drive shaft in the existing technology, effectively improving space utilization, and also preventing interference between the reducer and the connected conveyor equipment. Since the drive shaft does not need to be installed under the roller conveyor or other conveying equipment, the pallet landing distance is lower, which is convenient for manual pallet forklift docking. The equipment can be installed without digging a pit or with a shallow pit, which effectively reduces investment and subsequent maintenance costs. Lifting arms are installed on both sides of the bracket, and the conveyor chain machine 7 is installed on the bracket 6. The lifting arms 4, the rollers 5, and the guide wheels 10 work together to ensure the linear lifting and moving of the bracket 6, improving the stability of the lifting and moving of the bracket 6, and ensuring that the items carried on the conveyor chain machine 7 do not tilt or overturn.

[0028] The lifting reduction motor 1 and the conveyor chain machine 7 can be purchased from the market. The lifting reduction motor 1 and the conveyor chain machine 7 are equipped with power supplies. They are mature technologies in this field and have been fully disclosed. Therefore, they will not be described again in the specification.
