Description

Technical Field

[0001] This utility model belongs to the field of cantilever crane technology, and more specifically, it relates to a lightweight and easily detachable aluminum alloy cantilever crane. Background Technology

[0002] A cantilever crane is a lifting device used for lifting and moving heavy objects, typically consisting of a fixed support frame and a rotating boom. Its design allows for horizontal and vertical movement within a certain range, making it suitable for warehouses, workshops, and similar locations. Cantilever cranes effectively improve work efficiency and facilitate the handling of heavy objects. Depending on different needs, cantilever cranes can have varying load capacities and working radii.

[0003] Based on the above, the inventors have discovered the following problems: most existing cantilever cranes are installed and fixed with bolts during use. However, during installation and disassembly, workers need to align the cantilever crane with the support rod, which cannot be pre-fixed and may cause shaking, thus causing inconvenience to the workers during installation and disassembly and indirectly reducing the efficiency of installation or disassembly.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a lightweight and easy-to-disassemble aluminum alloy cantilever crane in order to achieve a more practical value. Utility Model Content

[0005] The purpose and effect of this utility model of a lightweight, easily detachable aluminum alloy cantilever crane are achieved by the following specific technical means:

[0006] A lightweight, easily detachable aluminum alloy cantilever crane includes a base, a support frame mounted on the top of the base, a frame body at one end of the support frame, a drive shaft inside the frame body, a frame at one end of the drive shaft, a limit mechanism inside the frame body, a connector connected to one end of the frame body, a boom mounted at one end of the connector, a movable component at the bottom end of the boom body, and a hook at the bottom end of the movable component.

[0007] Furthermore, the limiting mechanism includes a connecting rod, the surface of which is fitted with a spring, one end of which is connected to and installed with a limiting block, and one end of which is fitted with a trapezoidal locking block.

[0008] Furthermore, the surface of the frame is provided with an installation groove, and one end of the trapezoidal block is installed through the inside of the installation groove.

[0009] Furthermore, an installation block is fixedly installed at one end of the connector, and a slot is provided at the top of the installation block. The installation block is installed inside the installation slot, and the trapezoidal locking block is installed inside the slot.

[0010] Furthermore, a handle is connected and installed at the top of the frame, and one end of the handle passes through the frame and connects to the connecting rod inside.

[0011] Furthermore, the surface of the connector is provided with several sets of bolts.

[0012] Furthermore, the surface of the frame is provided with several sets of threaded holes, and one end of the bolt is connected to the inside of the threaded hole by a thread.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By utilizing the interlocking mechanism between the trapezoidal locking block and the slot, when installing the boom, workers can first align the mounting block on the connector with the mounting slot. Then, the trapezoidal locking block will automatically engage with the slot under the action of the spring, thus pre-fixing the connector and the boom. Afterward, workers can tighten the bolts into the threaded holes to fix the connector and the frame. The operation is very simple. When disassembly is required, the bolts can be removed first, and then the handle can be pulled to move the connecting rod and the trapezoidal locking block, thereby disassembling the connector and the boom. This indirectly improves the efficiency of installation and disassembly, and the design greatly increases practicality. Attached Figure Description

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 5 As shown:

[0027] This utility model provides a lightweight, easily detachable aluminum alloy cantilever crane, including a base 1, a support frame 2 installed at the top of the base 1, a frame body 3 provided at one end of the support frame 2, a drive shaft 4 provided inside the frame body 3, a frame 12 provided at one end of the drive shaft 4, a limit mechanism provided inside the frame 12, a connector 15 connected to one end of the frame 12, a boom 5 installed at one end of the connector 15, a moving component 6 provided at the bottom end of the boom 5, and a hook 7 provided at the bottom end of the moving component 6.

[0028] The limiting mechanism includes a connecting rod 13, a spring 18 is sleeved on the surface of the connecting rod 13, a limiting block 17 is connected and installed at one end of the connecting rod 13, and a trapezoidal locking block 16 is installed at one end of the limiting block 17.

[0029] The frame 12 has a mounting groove 14 on its surface, and one end of the trapezoidal block 16 is installed through the mounting groove 14.

[0030] One end of the connector 15 is fixedly fitted with an mounting block 9. The top of the mounting block 9 has a slot 10. The mounting block 9 is installed inside the mounting slot 14, and the trapezoidal locking block 16 is installed inside the slot 10. Through the cooperation between the trapezoidal locking block 16 and the slot 10, when the operator installs the boom, they can first align the mounting block 9 on the connector 15 with the mounting slot 14 for installation. Then, the trapezoidal locking block 16 will automatically lock into the slot 10 under the action of the spring 18, thereby pre-fixing the connector 15 and the boom 5. Then, the operator can fix the connector 15 and the frame 12 by tightening the bolt 8 into the threaded hole 19. The operation steps are very simple. When disassembly is required, the bolt 8 can be removed first, and then the handle 11 can be pulled to move the connecting rod 13 and the trapezoidal locking block 16, thereby disassembling the connector 15 and the boom 5. This indirectly improves the efficiency of installation and disassembly, and the design greatly increases the practicality.

[0031] The top of the frame 12 is connected to a handle 11, one end of which passes through the frame 12 and connects to the connecting rod 13 inside.

[0032] The surface of the connector 15 is provided with several sets of bolts 8.

[0033] The frame 12 has several sets of threaded holes 19 on its surface, and one end of the bolt 8 is threaded into the threaded hole 19.

[0034] The specific usage and function of this embodiment are as follows:

[0035] Before installation and use, the operator needs to inspect the internal components or structure of the cantilever crane. Once the inspection is completed, it can be used normally. When installing the boom, the operator can first align the mounting block 9 on the connector 15 with the mounting groove 14. Then, the trapezoidal locking block 16 will automatically engage with the groove 10 under the action of the spring 18, thus pre-fixing the connector 15 and the boom 5. Then, the operator can tighten the bolt 8 into the threaded hole 19 to fix the connector 15 and the frame 12. The operation steps are very simple. When disassembly is required, the bolt 8 can be removed first, and then the handle 11 can be pulled to move the connecting rod 13 and the trapezoidal locking block 16, thus disassembling the connector 15 and the boom 5. This indirectly improves the efficiency of installation and disassembly, and the design greatly increases the practicality. If it needs to be used again, the above operation can be repeated.
