Description

Technical Field

[0001] This utility model belongs to the field of automation equipment, and relates to a lifting and transferring device, particularly a cylinder-type lifting and transferring device. Background Technology

[0002] In automated logistics and production lines, lifting and transferring devices are widely used for material diversion, merging, and reversal. Traditional electric lifting mechanisms suffer from complex structures, high costs, and slow speeds; while cylinder lifting is low-cost and fast, it has significant drawbacks: multiple cylinders are difficult to operate synchronously, easily leading to tilting and jamming of the loading platform; rigid connections are difficult to accommodate installation errors or frame deformation, easily causing cylinders to be subjected to lateral forces and damaged; at the same time, there is a lack of effective mechanisms to ensure the synchronous start and stop of the transmission chain. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a cylinder-type lifting and transfer system to solve these problems.

[0004] The purpose of this utility model can be achieved through the following technical solution: a cylinder-type lifting and transferring device, including a base frame and a frame, wherein the bottom of the base frame is provided with a plurality of support feet for supporting and fixing the device, characterized in that the frame is located above the base frame and can be lifted and moved, and the frame is provided with a plurality of chain assemblies that can drive objects to move.

[0005] A synchronization device for driving the chain assembly is provided below the frame.

[0006] The base frame is equipped with a leveling device to maintain the frame in a horizontal state during the lifting process;

[0007] The base frame is also equipped with multiple lifting cylinders for driving the frame to be lifted as a whole. The lifting cylinders are connected to the bottom of the frame through cylinder flange joints.

[0008] The bolt hole diameter on the cylinder flange joint is larger than the bolt hole diameter on the frame, forming a structure that is larger at the bottom and smaller at the top to achieve fine adjustment.

[0009] In the above-mentioned cylinder-type lifting and transferring device, the synchronization device includes a drive shaft, bearing seats at both ends of the drive shaft, a servo motor for driving the drive shaft, and a plurality of sprockets spaced apart on the drive shaft. The number of sprockets is the same as the number of chain assemblies and corresponds one-to-one. The sprockets are connected to the corresponding chain assemblies through a drive chain.

[0010] In the above-mentioned cylinder-type lifting and transferring device, the horizontal device consists of multiple mechanical synchronizers to ensure the synchronous movement of multiple lifting cylinders, and two adjacent synchronizers are connected by a connecting shaft to maintain horizontal synchronous movement.

[0011] In the aforementioned cylinder-type lifting and transferring device, the bolted connection structure between the cylinder flange joint and the frame allows for fine-tuning of the position during assembly to accommodate installation errors or frame deformation.

[0012] In the aforementioned cylinder-type lifting and transfer device, the bottom of the support foot is designed with a duck-foot structure to improve its support and fixation strength.

[0013] Compared with existing technologies, this cylinder-type lifting and transferring device has the following advantages:

[0014] 1. By using a mechanical synchronizer and servo motor drive, the multi-chain components and lifting cylinders are synchronized to avoid jamming or tilting caused by asynchrony, thus ensuring the smoothness of the lifting and transmission process.

[0015] 2. Servo motor drive in conjunction with synchronization device can achieve precise control, suitable for lifting, transfer and positioning stations in automated production lines, improving production efficiency and system integration capabilities;

[0016] 3. The special bolt hole design of the cylinder flange joint provides fine-tuning capability during installation, enhances the equipment's adaptability to manufacturing errors and frame deformation, and improves assembly efficiency and operational reliability. Attached Figure Description

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figure 1 As shown, this cylinder-type lifting and transferring device includes a base frame 1 and a frame 2. The base frame 1 has multiple support feet 3 at its bottom for supporting and fixing the device. The frame 2 is located above the base frame 1 and can be raised and lowered. The frame 2 has multiple chain assemblies 13 that can move objects. The frame 2 has a synchronization device below it for driving the chain assemblies 13. The base frame 1 has a leveling device to keep the frame 2 horizontal during the lifting process. The base frame 1 also has multiple lifting cylinders 4 for driving the frame 2 to lift as a whole. The lifting cylinders 4 are connected to the bottom of the frame 2 through cylinder flange joints 5. The bolt hole diameter on the cylinder flange joint 5 is larger than the bolt hole diameter on the frame 2, forming a structure that is larger at the bottom and smaller at the top to achieve fine adjustment.

[0023] The synchronization device includes a drive shaft 6, bearing seats 7 at both ends of the drive shaft 6, a servo motor 8 for driving the drive shaft 6, and multiple sprockets 9 spaced apart on the drive shaft 6. The number of sprockets 9 is the same as the number of chain assemblies 13 and corresponds one-to-one. The sprockets 9 are connected to the corresponding chain assemblies 13 via a drive chain 10. The horizontal device consists of multiple mechanical synchronizers 11 to ensure the synchronous movement of multiple lifting cylinders 4. Two adjacent synchronizers 11 are connected by a connecting shaft 12 to maintain horizontal synchronous movement. The bolted connection structure between the cylinder flange joint 5 and the frame 2 allows for fine-tuning of the position during assembly to accommodate installation errors or deformation of the frame 2. The bottom of the support foot 3 has a duck-foot structure to improve its support and fixation strength. The duck-foot structure of the support foot 3 increases the contact area with the ground, improves the overall support strength and anti-overturning ability, and is suitable for heavy-duty or high-frequency operation environments.

[0024] The working principle of this cylinder-type lifting and transferring device is as follows: The device drives the frame 2 to move up and down as a whole through multiple lifting cylinders 4 on the base frame 1. A chain assembly 13 is installed on the frame 2 for transporting objects. A synchronization device is driven by a servo motor 8 to drive the transmission shaft 6, which in turn drives all the chain assemblies 13 to operate synchronously through sprockets 9 and transmission chains 10, ensuring smooth material transport. A leveling device consists of multiple mechanical synchronizers 11, linked by a connecting shaft 12 to ensure that the multiple lifting cylinders 4 move synchronously during lifting, thereby maintaining the horizontal state of the frame 2. The cylinder flange joint 5 adopts a bolt hole diameter design with a larger diameter at the bottom and a smaller diameter at the top, allowing for fine adjustments during assembly to accommodate installation errors or deformation of the frame 2, improving assembly accuracy and operational stability.
