The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0036] like Figure 1-4 As shown, a lifting device that is easy to assemble and disassemble includes a frame assembly and a lifting device 1. The frame assembly includes a crossbeam 2 and support assemblies 3 disposed opposite to both ends of the crossbeam 2.

[0037] The support assembly 3 is angled relative to the crossbeam 2. The support assembly 3 includes an upper support 31 and a lower support 32 that can be detachably or foldably connected.

[0038] The end of the upper support 31 away from the lower support 32 is detachably connected to the crossbeam 2;

[0039] A caster assembly 4 is provided at the end of the lower support 32 that is away from the upper support 31;

[0040] A lifting device 1 is installed on the crossbeam 2 and is slidably connected to the crossbeam 2 from left to right.

[0041] In this embodiment, when the barrel of the extruder needs to be replaced due to defects such as water leakage, seepage, or cracks, the upper support 31 and the crossbeam 2 are assembled sequentially with the assistance of a forklift at the barrel replacement location in the workshop. After the lifting device is completed, the barrel is first lifted in the middle of the crossbeam 2 by the crane 1, then moved to both sides and then the barrel is unloaded, thereby realizing the lifting and transfer of the barrel disassembly process.

[0042] The above structure, due to its detachable frame component design, reduces the assembly difficulty of the lifting device, making it easy to disassemble, assemble, and use. Moreover, it has low requirements for workshop space and is suitable for occasions where cranes and forklifts are difficult to operate.

[0043] Furthermore, such as Figure 1 , 3 As shown in Figure 4, in order to ensure the smooth and safe left and right movement of the lifting device 1, the crossbeam 2 is an I-beam, and a traveling trolley 5 is provided between the crossbeam 2 and the lifting device 1.

[0044] The lifting device 1 is detachably connected to the traveling trolley 5.

[0045] In this embodiment, the walking vehicle 5 can be either powered or unpowered, depending on the application scenario.

[0046] Furthermore, such as Figure 1 , 3 As shown in Figure 4, in order to improve the stability of the support assembly 3, the upper support 31 is an A-shaped structure and the lower support 32 is a trapezoidal structure.

[0047] The lower two ends of the A-shape of the upper support 31 are detachably connected to the upper end face of the lower support 32;

[0048] After the upper support 31 and the lower support 32 are connected, the support assembly 3 forms a triangular shape.

[0049] Furthermore, such as Figure 2 , 4 As shown, in order to improve the connection stability between the upper support 31 and the lower support 32, a connecting component 6 is provided at the connection between the lower support 32 and the upper support 31.

[0050] The connecting assembly 6 includes an upper connecting plate 61, a lower connecting plate 62, and a first locking member (not shown in the figure);

[0051] The upper connecting plate 61 and the lower connecting plate 62 are respectively fixedly connected to the lower support 32 and the lower support 32;

[0052] The upper connecting plate 61 and the lower connecting plate 62 have the same structure, and the upper connecting plate 61 and the lower connecting plate 62 have corresponding mounting holes 10 on their outer periphery.

[0053] The first locking member is used to fix the upper connecting plate 61 and the lower connecting plate 62 after passing through the mounting hole 10.

[0054] In this embodiment, the first locking member includes a bolt and a nut. The bolt passes through the mounting hole 10 and is locked by screwing the nut to the bolt, thereby making the upper connecting plate 61 and the lower connecting plate 62 stable and securely fixed.

[0055] Furthermore, such as Figure 1 , 2As shown in Figures 3 and 4, in order to improve the stability and reliability of the connection between the crossbeam 2 and the support assembly 3, the upper support 31 is connected to the end of the crossbeam 2 around the perimeter by a second locking member (not shown in the figure).

[0056] In this embodiment, the second locking component is a locking screw, which locks the perimeter of the connection between the end of the crossbeam 2 and the upper support 31 to achieve a fixed connection.

[0057] Furthermore, such as Figure 1 As shown, the lifting device 1 is an electric or manual chain hoist.

[0058] Furthermore, such as Figure 1 As shown, in order to improve the mobility of the lifting device, the caster assembly 4 is a swivel caster.

[0059] Furthermore, to improve assembly convenience and efficiency, as well as ease of placement, the upper support 31 is rotatably hinged to the lower support 32 via a hinge (not shown in the figure).

[0060] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
