[0001] This utility model belongs to the technical field of mechanical transportation and lifting equipment, specifically a simple, stable and efficient pallet lifting device. Background Technology

[0002] In industrial production, after the core assembly operation is completed on a fixed pallet, the pallet and cores usually need to be transferred to another location. Currently, there are two main transfer methods: one is to use a forklift to move the pallet and cores; the other is to use an overhead crane to lift the pallet for transfer.

[0003] However, the following problems were found in the implementation of the relevant technologies: When using forklifts for transport, space needs to be reserved for forklift operations within the production area, which may increase site occupancy. When using overhead cranes for lifting and transport, overhead crane resources will be occupied for a long time, affecting the use of overhead cranes in other processes. Furthermore, it is difficult to achieve automated linkage with the production system using either method, requiring separate personnel to operate, which increases labor costs and operational complexity. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a simple, stable, and efficient pallet lifting device with advantages such as simple structure, cost savings, and high automation. This invention utilizes a lifting structure composed of a frame, guide columns, trolleys, and hydraulic cylinders, combined with a flatcar, to achieve forklift-free and crane-free transport, solving the problems of relying on forklifts for handling and overhead cranes for lifting. Furthermore, by interlocking with the core system, no individual operator is required, addressing the issues of high labor costs and difficulty in achieving automated linkage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a simple, stable, and efficient pallet lifting device, comprising a frame, a guide column, a trolley, a hydraulic cylinder, an adjustable support component, and a top cover. The guide column is fixedly installed, and the trolley is equipped with a pulley, which is embedded inside the guide column. The trolley slides in conjunction with the guide column through the pulley. The output end of the hydraulic cylinder is connected to the trolley.

The top of the adjustable support component is higher than the upper surface of the frame, and the top of the trolley corresponds to the bottom of the adjustable support component.

[0006] Preferably, the guide post is vertically fixed on the frame, and the trolley is located inside the guide post and fits against the inner wall of the guide post.

[0007] Preferably, the cylinder body end of the hydraulic cylinder is connected to the frame, and the piston rod end of the hydraulic cylinder is connected to the bottom of the trolley.

[0008] Preferably, the adjustable supports are distributed at lateral intervals along the frame, and the bottom of the adjustable supports is fixedly connected to the upper surface of the frame.

[0009] Preferably, the edge of the top cover is connected to the top edge of the frame, and the top cover covers a predetermined area on the upper part of the frame.

[0010] Preferably, there are two guide posts, which are symmetrically distributed on both sides of the frame, and the two ends of the trolley are respectively connected to the two guide posts by pulleys.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 3 As shown, this utility model provides a simple, stable, and efficient pallet lifting device, including a frame 1, guide column 2, trolley 3, hydraulic cylinder 4, adjustable support 5, and top cover 6. The guide column 2 is fixedly installed, and the trolley 3 is equipped with pulleys that are embedded inside the guide column 2. The trolley 3 slides in conjunction with the guide column 2 through the pulleys. The output end of the hydraulic cylinder 4 is connected to the trolley 3. The adjustable support 5 is installed on the frame 1, and the top cover 6 is installed on the upper part of the frame 1. The top of the adjustable support 5 is higher than the upper surface of the frame 1, and the top of the trolley 3 corresponds to the bottom of the adjustable support 5. A transfer flatcar carries the pallet to the device. When in position, the cylinder body of the hydraulic cylinder 4 is fixed to the frame 1, and the piston rod pushes the trolley 3. The pulleys at both ends of the trolley 3 are embedded in the two guide posts 2 symmetrically distributed on both sides of the frame 1, and the trolley 3 is in contact with the inner wall of the guide post 2, so it can slide stably upward along the guide post 2. As the trolley 3 rises, its top contacts the bottom of the adjustable support 5, causing the adjustable support 5 (which is distributed laterally along the frame 1 and fixedly connected to the upper surface of the frame 1 at its bottom) to press against the pallet until the trolley 3 rises to the top of the guide post 2 and stops. At this time, the pallet is completely lifted and the transfer flatcar drives away.

[0019] Specifically, the guide post 2 is vertically fixed on the frame 1, and the trolley 3 is located inside the guide post 2 and fits against the inner wall of the guide post 2, ensuring that the trolley 3 will not deviate during the up and down sliding process, thereby improving the stability and accuracy of the sliding.

[0020] Furthermore, the cylinder body end of the hydraulic cylinder 4 is connected to the frame 1, and the piston rod end of the hydraulic cylinder 4 is connected to the bottom of the trolley 3. The hydraulic cylinder 4 drives the trolley 3 to descend to the lowest position, and the gantry robot completes the core assembly on the pallet. After the core assembly is completed, the hydraulic cylinder 4 pushes the trolley 3 to rise along the guide column 2 to the top. The system interlocks and controls the transfer flatcar to return to the device position. The hydraulic cylinder 4 drives the trolley 3 and the pallet on the adjustable support 5 to descend, so that the pallet falls back to the flatcar. The flatcar transports the core-assembled pallet to the next process.

[0021] Furthermore, the adjustable support members 5 are distributed laterally along the frame 1, and the bottom of the adjustable support members 5 is fixedly connected to the upper surface of the frame 1. This distribution method can evenly distribute the weight of the pallet, avoid excessive local stress that could cause the pallet to tilt or be damaged, and the fixed connection ensures that the adjustable support members 5 will not loosen when supporting the pallet.

[0022] It is worth noting that the edge of the top cover 6 is connected to the top edge of the frame 1, and the top cover 6 covers the preset area on the upper part of the frame 1. The top cover 6 on the upper part of the frame 1 (with its edge connected to the top edge of the frame 1 and covering the preset area on the upper part) can prevent the truss from impacting the device when it moves to assemble the core.

[0023] It is worth noting that there are two guide columns 2, which are symmetrically distributed on both sides of the frame 1. The two ends of the trolley 3 are respectively connected to the two guide columns 2 through pulleys. The double-sided guide columns 2 provide double-sided guiding support for the trolley 3, further enhancing the stability of the trolley 3 when it is raised and lowered, and preventing the trolley 3 from shaking.

[0024] It is worth mentioning that the hydraulic cylinder 4 is located between the two guide posts 2, and the axis of the hydraulic cylinder 4 is parallel to the axis of the guide post 2. This ensures that the driving force of the hydraulic cylinder 4 on the trolley 3 is in the central area of ​​the trolley 3 and is consistent with the sliding direction of the trolley 3, thus avoiding the trolley 3 from jamming or aggravating wear due to force deviation.

[0025] It is worth emphasizing that a base plate 7 is fixedly installed on the lower surface of the frame 1, and several bolt grooves 8 are opened on the upper surface of the base plate 7. The base plate 7 fixed on the lower surface of the frame 1 achieves stable installation of the device on the ground through the bolt grooves 8, ensuring the overall operational stability.

[0026] The hydraulic cylinder 4 and the trolley 3 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switches, which are not the main technical points of this patent and will not be described in detail. The "front, rear, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.

[0027] Working principle: When the transfer flatcar carries the pallet to the device position, the cylinder end of the hydraulic cylinder 4 is fixed on the frame 1, and the piston rod end pushes the trolley 3. The pulleys at both ends of the trolley 3 are embedded in the two guide columns 2 symmetrically distributed on both sides of the frame 1, and the trolley 3 is in close contact with the inner wall of the guide column 2, so it can slide stably upward along the guide column 2. As the trolley 3 rises, its top contacts the bottom of the adjustable support 5, causing the adjustable support 5 (which is distributed laterally along the frame 1 and fixedly connected to the upper surface of the frame 1 at its bottom) to press against the pallet until the trolley 3 rises to the top of the guide column 2 and stops. At this time, the pallet is completely lifted and the transfer flatcar drives away.

[0028] Afterwards, cylinder 4 drives trolley 3 to descend to its lowest position, and the gantry robot completes the core assembly on the pallet. After the core assembly is completed, cylinder 4 pushes trolley 3 again to rise along guide post 2 to the top. The system interlocks and controls the transfer flatcar to return to the device position. Cylinder 4 drives the pallet on trolley 3 and adjustable support 5 to descend, so that the pallet falls back onto the flatcar. The flatcar transports the assembled pallet to the next process. During the process, the top cover 6 on the upper part of frame 1 (with its edge connected to the top edge of frame 1, covering the upper preset area) can prevent the gantry from hitting the device when it moves to assemble the core. The base plate 7 fixed to the lower surface of frame 1 achieves stable installation of the device on the ground through bolt grooves 8, ensuring overall operational stability.
