Description

Technical Field

[0001] This utility model relates to the field of transfer equipment technology, and in particular to a lifting and unloading device. Background Technology

[0002] After PPR pipe fittings with inserts are manufactured, they need to be marked, counted, and packaged. During packaging, the products are typically arranged in frames, and the entire frame is manually poured into the packaging equipment.

[0003] The weight of a whole crate of products is about 50KG. This method relies heavily on manual handling and dumping, which is not only extremely labor-intensive and inefficient, but also poses a high risk of workplace injuries. In addition, manual operation makes it difficult to avoid material spillage during dumping, which affects product quality and the workshop environment. Utility Model Content

[0013] Compared to the beneficial effects achieved by existing technologies:

[0014] This product's lifting and unloading device effectively solves the problems of cumbersome operation, high labor intensity, and numerous safety hazards associated with traditional unloading methods by rotating the lifting frame onto a horizontal support shaft and using a dedicated drive component to control the lifting frame to drive the material frame containing the product to rotate. This structure achieves stable lifting and controllable rotation of the material frame, significantly improving the automation level and operational efficiency of the unloading process. It also avoids material spillage that may occur during manual operation, improving the working environment. Its compact structure and reliable, coordinated movements reduce the workload of operators and are suitable for product material transfer and unloading needs in various industrial scenarios, offering high practicality and safety.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example:

[0021] Reference Figure 1 and Figure 2This application discloses a lifting and unloading device, comprising a fixed frame 1, a horizontal support shaft 2 rotatably mounted on the top of the fixed frame 1, and a lifting frame 3 for placing a material frame 12 inside the fixed frame 1. The top of the lifting frame 3 is higher than the top of the fixed frame 1, and one side of the top of the lifting frame 3 is rotatably connected to the support shaft 2. This arrangement facilitates the connection between the lifting frame 3 and the support shaft 2 at the top of the fixed frame 1. Bearing seats 8 are provided at the connection points between the support shaft 2 and the fixed frame 1 and the lifting frame 3, respectively. Through the provision of several bearing seats 8, the support shaft 2 can be effectively rotated at the top of the fixed frame 1.

[0022] like Figure 1 and Figure 2 As shown, the fixed frame 1 is equipped with a drive assembly for driving the lifting frame 3 to rotate around the support shaft 2. The drive assembly includes a lifting shaft 4 and two lifting cylinders 5. The lifting shaft 4 is rotatably mounted on the lifting frame 3, and the axes of the lifting shaft 4 and the support shaft 2 are parallel to each other. Fixed seats 6 are fixedly mounted on both sides of the bottom of the fixed frame 1 at the ends of the lifting shaft 4. One end of each of the two lifting cylinders 5 is hinged to one of the two fixed seats 6. This hinged connection allows for the installation of a rotating shaft on the fixed seat 6, enabling the bottom of the lifting cylinder 5 to be rotatably connected to the rotating shaft. Fisheye connectors 9 are fixedly mounted on the telescopic ends of both cylinders, and the two fisheye connectors 9 are rotatably fitted onto both ends of the lifting shaft 4. This arrangement effectively allows the lifting shaft 4 to rise and fall through the telescopic movement of the lifting cylinders 5, driving the lifting frame 3 to rotate around the support shaft 2, causing the material frame 12 inside the lifting frame 3 to flip and dump the product inside the material frame 12 into the storage bin 13. Figure 1 As shown, the lifting frame 3 is equipped with several limiting plates 7 to prevent the material frame 12 from moving during unloading. These limiting plates 7 are specifically located within the lifting frame 3 and on both sides of the top of the material frame 12. During unloading, they abut against the top sides of the material frame 12 and support and limit its movement. The fixing base 6 has several connecting holes 10, each with an expansion screw 11 inserted into it. The connecting holes 10 and expansion screws 11 facilitate the fixing of the overall position of the fixing frame 1.

[0023] Working principle:

[0024] During operation, the material frame 12 containing the material is placed inside the lifting frame 3 and fixed by several limiting plates 7 within the frame to prevent displacement during subsequent actions. After the equipment is started, the lifting cylinders 5 installed on both sides of the bottom of the fixed frame 1 begin to work. The cylinder extension rod pushes the lifting shaft 4 connected to it upward through the fisheye joint 9 at its top. Since the lifting shaft 4 is rotatably mounted on the lifting frame 3, and the top side of the lifting frame 3 is rotatably connected to the horizontal support shaft 2 at the top of the fixed frame 1 through the bearing seat 8, when the lifting shaft 4 is lifted by the cylinder, it forces the entire lifting frame 3 to rotate and flip stably around its hinge point with the support shaft 2. During this process, the material frame 12 inside the lifting frame 3 tilts along with the frame, thereby achieving the purpose of smoothly and controllably pouring the product inside the frame into the storage bin 13 below or into the packaging equipment.

[0025] After unloading is complete, the lifting cylinder 5 retracts, pulling the lifting shaft 4 back down, causing the lifting frame 3 to rotate in the opposite direction and return to its initial horizontal position for the next loading operation. The entire device converts the linear drive of the cylinder into the rotational motion of the lifting frame 3. The structure is reliable and the operation is smooth, effectively realizing the automated unloading of the heavy-duty material frame 12, greatly reducing the intensity of manual labor, and ensuring operational safety and unloading efficiency.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
