Description

Technical Field

[0001] This utility model belongs to the field of material lifting technology, and specifically relates to a cylindrical material lifting device. Background Technology

[0002] In industrial sites such as factory areas and logistics warehouses, the handling, loading, unloading, and stacking of goods are generally carried out by special motorized industrial vehicles within the factory. For example, forklifts can lift loads to a certain height through masts and forks for stacking operations, while tractors, pushers, and handling vehicles can be used to tow, push, or move goods.

[0003] In many fields such as industrial production and logistics transportation, the handling and lifting of cylindrical materials are frequently involved. For example, in the paper industry, paper rolls, as typical cylindrical materials, need to be transferred from the production line to warehouse storage after production, or lifted during subsequent processing to meet the needs of different processes; in the building materials industry, some large pipe-like cylindrical materials need to be lifted to a specific height for installation at construction sites. Utility Model Content

[0004] This utility model addresses the problems in the prior art by providing a cylindrical material lifting device, which is installed on a transport vehicle for lifting cylindrical materials. The specific technical solution is as follows:

[0005] A cylindrical material lifting device is installed on a vehicle frame and includes a lifting assembly. The vehicle frame includes two base plates, a side facade, and a connecting plate. The two base plates are arranged horizontally side by side. The side facade is connected above the two base plates. The connecting plate is connected between the two base plates to form an I-beam load-bearing structure.

[0006] The lifting assembly includes a boom and a lifting cylinder. One end of the boom is rotatably connected to the side facade, and the free end of the boom is used to lift materials. One end of the lifting cylinder is rotatably connected to a connecting plate, and the other end of the lifting cylinder is rotatably connected to the boom. The boom rotates with the extension and retraction of the lifting cylinder.

[0007] As a further technical solution of this utility model, the slewing frame includes two side plates and a support plate. The two side plates are arranged side by side and one end of each is rotatably connected to the side facade. The support plate is connected between the two side plates to form an I-beam structure.

[0008] As a further technical solution of this utility model, the slewing arm frame also includes a notch, the notch opening upward and disposed at the free end of the side plate.

[0009] As a further technical solution of this utility model, the inner circumference of the notch is evenly distributed with rolling balls along its trajectory, and the rolling balls can form a rolling support surface for the horizontal axis.

[0010] As a further technical solution of this utility model, the free end of the swing arm is equipped with a horizontal shaft, and both ends of the horizontal shaft are detachably connected with baffles, which fit against the outer side wall of the side plate.

[0011] The beneficial effects of this utility model are as follows:

[0012] (1) In this application, the lifting component is set up to drive the free end of the boom to rotate upward based on the lifting cylinder to lift the cylindrical material. At the same time, the boom can be parallel to the bottom plate when it rotates downward. The small volume design makes the lifting device occupy very little space on the forklift, does not affect other operating functions of the forklift, and can flexibly move through narrow working areas, making it suitable for more complex working environments.

[0013] (2) In this application, by setting the notch and the ball bearing support surface, the center of gravity of the cylindrical material can be lower when it rises, so as to ensure the stability of the cylindrical material during the lifting process. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Figure 1 This diagram shows the overall structure of the cylindrical material lifting device after installation. Figure 1 In this invention, the cylindrical material lifting device includes a lifting assembly 200 mounted on a frame 100 for lifting cylindrical materials on the frame 100; a jack 300 is also mounted at the rear of the frame 100. In the prior art, the frame 100 and the jack 300 constitute a forklift for handling cylindrical materials.

[0021] Figure 2 A structural schematic diagram of the frame 100 and the lifting assembly 200 is shown; Figure 2 In the frame 100, there are two base plates 110, a side facade 120, and a connecting plate 130. The two base plates 110 are arranged horizontally side by side, the side facade 120 is connected above the two base plates 110, and the connecting plate 130 is connected between the two base plates 110 to form an I-beam load-bearing structure. The connecting plate 130 and the two base plates 110 are located on the same horizontal plane, and the three together form an I-beam load-bearing structure to support the materials to be transported. The side facade 120 is vertically arranged and connected above the two base plates 110, and the side facade 120 is adjacent to the jack 300. Used as an intermediate connecting component for connecting the jack 300; the lifting assembly 200 includes a boom 210 and a lifting cylinder 220. One end of the boom 210 is rotatably connected to the side facade 120, and the free end of the boom 210 is used to lift materials. One end of the lifting cylinder 220 is rotatably connected to the connecting plate 130, and the other end of the lifting cylinder 220 is rotatably connected to the boom 210. The boom 210 rotates with the extension and retraction of the lifting cylinder 220. The lifting cylinder 220 itself is powered by an external power source, which can be hydraulically driven or pneumatically driven. When the lifting cylinder 220... When extended, the lifting cylinder 220 pushes the boom 210 to rotate upward around its connection axis with the side facade 120, raising the free end of the boom 210 to lift the cylindrical material. When the lifting cylinder 220 retracts, it pulls the boom 210 to rotate downward around its connection axis with the side facade 120, causing the boom 210 to rotate downward and its free end to fall to lower the cylindrical material. Simultaneously, the boom 210 rotates downward parallel to the base plate 110, thus concealing the lifting assembly 200 and avoiding... To avoid occupying too much space above the chassis, the compact design of this lifting device minimizes its footprint on the forklift, does not affect other forklift operations, and allows for flexible movement through narrow work areas, making it suitable for more complex operating environments. The rotating lifting method allows for multi-angle adjustment of the position of cylindrical materials, making it easier to accurately position and place them, reducing material impact damage. It can flexibly complete lifting tasks under different working conditions and can enhance stability during the lifting process to a certain extent, reducing safety risks such as material shaking and slippage, and reducing the probability of accidents.

[0022] Figure 3 A schematic diagram of the structure of the swing arm 210 and the horizontal axis 230 is shown; Figure 3In the slewing boom 210, two side plates 211, a support plate 212, and a notch 213 are included. The two side plates 211 are arranged side by side and one end of each is rotatably connected to the side facade 120. The support plate 212 is connected between the two side plates 211 to form an I-beam structure, thereby further increasing the structural strength of the slewing boom 210, making it suitable for heavy cylindrical materials and improving the applicability of the device. The notch 213 opens upward and is located at the free end of the side plates 211. The notch 213 can support the support shaft, making the horizontal shaft 230 more stable when placed at the free end of the slewing boom 210, and the two form a mutually compatible load-bearing structure. Ball bearings are evenly distributed along the trajectory of the inner circumference of the notch 213. Several ball bearings can form a support surface for the horizontal shaft 230, so that there is a gap between the horizontal shaft 230 and the inner wall of the notch 213. In this way, the horizontal shaft 230 can support the horizontal shaft 230. The horizontal shaft 230 can rotate automatically as the lifting angle changes to ensure its stability during the lifting process. This is because the mass of the material in the circumferential direction is not uniform. By utilizing the self-rotation of the horizontal shaft 230, the position with the greatest circumferential mass of the cylindrical material can be located at the bottom, ensuring the stability of the cylindrical material during the lifting process. The free end of the boom 210 is equipped with the horizontal shaft 230, and both ends of the horizontal shaft 230 are detachably connected to baffles 231, which fit against the outer wall of the side plate 211. The horizontal shaft 230 carries the cylindrical material, and after the lifting end of the boom 210 is placed on it, the baffles 231 are installed at the end of the horizontal shaft 230. The two baffles 231 restrict the axial position of the horizontal shaft 230, ensuring that the horizontal shaft 230 does not undergo axial displacement during the lifting process.

[0023] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
