Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and more particularly to a lifting tool. Background Technology

[0002] Container ships, also known as container ships, are vessels specifically designed to carry international standard container ships. The column supports of a container ship are crucial components for stacking containers. The installation quality of the column directly affects the stability and safety of container stacking. Therefore, during installation, the column needs continuous positioning and adjustment to ensure it aligns with the positioning holes or bases on the ship.

[0003] Due to the structural and weight constraints of the box columns, construction workers cannot rely solely on manual labor for handling and installation adjustments during the installation and transportation process; hoisting machinery must be used.

[0004] To save costs, small-tonnage truck cranes are generally used for lifting and transporting box columns during the prefabrication stage. However, the use of small-tonnage truck cranes requires a large construction site and cannot be moved quickly after each lifting operation. During the installation stage of the box columns, the limited space on the ship's deck prevents the placement of small-tonnage truck cranes, and the ship's height limits the use of large-tonnage truck cranes for lifting and installation on the ground. This not only occupies limited ground lifting resources but also results in low construction efficiency and affects the ship's construction efficiency.

[0005] Therefore, a lifting tool is urgently needed to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a lifting tool that can use a forklift to lift and transport box columns, thereby reducing the occupation of ground lifting resources and ensuring the reliability and efficiency of box column lifting and transportation.

[0044] Embodiments of the present invention are described in detail below.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0045] Figure 1 A schematic diagram of the lifting tool provided in an embodiment of the present invention is shown. In the figure, the X, Y, and Z directions are perpendicular to each other. (Refer to...) Figure 1 This embodiment provides a lifting tool, which includes a forklift connecting frame 100, an anti-slip fixing device 200, and an anti-slip fixing device 200.

[0046] Specifically, the forklift connecting frame 100 has a positioning channel 110 inside, into which the forklift forks can extend. The lifting connection mechanism 300 is connected to the forklift connecting frame 100 and is configured to connect to the material to be lifted. Through the forklift connecting frame 100 and the lifting connection mechanism 300, the forklift forks and the material to be lifted can be connected, enabling the lifting and transportation of the material with the help of the forklift, reducing the occupation of ground lifting resources. The anti-slip fixing device 200 is set in the positioning channel 110, which can fix the forklift forks in the positioning channel 110 to ensure the stability and reliability of the lifting of the material.

[0047] Figure 2 Show Figure 1 A magnified view of a section marked A in the middle; Figure 3 An exploded view of the movable connection mechanism provided in an embodiment of the present invention is shown. (Refer to...) Figures 1-3 The forklift connecting frame 100 has a connecting lug 140 at its bottom in the Z direction. The connecting lug 140 has a connecting hole 141, which is configured to connect to the lifting connecting mechanism 300.

[0048] Specifically, the lifting connection mechanism 300 includes a connecting cable 310 and a hook assembly 320. The connecting cable 310 is hooked and connected to the connecting hole 141. The hook assembly 320 is connected to the end of the connecting cable 310 away from the connecting lug 140. The hook assembly 320 is configured to connect to the material to be lifted. In this embodiment, the connecting cable 310 can be a chain or the like. The hook assembly 320 can be a hook with an anti-detachment buckle, as is available in the prior art.

[0049] More specifically, the lifting connection mechanism 300 also includes a movable connection mechanism 330. The movable connection mechanism 330 includes a pivot 331, a first connector 332, and a second connector 333. The pivot 331 is located at the top of the hook assembly 320. Both the first connector 332 and the second connector 333 are connected to the pivot 331 and can swing about the pivot 331. The first connector 332 and the second connector 333 are interlocked to form a connection channel 334, and the connecting cable 310 passes through and is connected to the connection channel 334. Through the swingable connection of the first connector 332 and the second connector 333 relative to the hook assembly 320, the lifting flexibility of the material to be lifted can be improved.

[0050] More specifically, the top of the hook assembly 320 is provided with two mounting seats 335 spaced apart. The two ends of the rotating shaft 331 are respectively connected to one mounting seat 335, thus leaving a certain gap between the rotating shaft 331 and the top of the hook assembly 320. Both the first connector 332 and the second connector 333 have an arc-shaped structure. Taking the first connector 332 as an example, its bottom end is integrally formed with a hollow cylindrical connecting portion. The rotating shaft 331 passes through this hollow cylindrical connecting portion, and there is a gap between the circumference of the rotating shaft 331 and the inner wall of the hollow cylindrical connecting portion, so as to achieve a rotatable connection between the first connector 332 and the rotating shaft 331.

[0051] More specifically, the movable connection mechanism 330 also includes a bolt 336 and a nut 337. The top of the first connector 332 is integrally formed with a first bolt mounting lug, and the top of the second connector 333 is integrally formed with a second bolt mounting lug. The bolt 336 passes sequentially through the second bolt mounting lug and the first bolt mounting lug, and the nut 337 is screwed onto the bolt 336. The second bolt mounting lug and the first bolt mounting lug are clamped between the heads of the nut 337 and the bolt 336.

[0052] Figure 4 This diagram shows a partial structural schematic of the anti-slip fixing device and forklift connecting frame provided in an embodiment of the present invention; Figure 5 A schematic diagram of the pushing mechanism provided in an embodiment of the present invention is shown. (Refer to...) Figure 1 , Figure 4 and Figure 5The anti-slip fixing device 200 includes a pressing mechanism 210 and a pushing mechanism 220. The pressing mechanism 210 has a guide slope 211 at its bottom in the Z direction, and the pushing mechanism 220 has a supporting slope 221 at its top in the Z direction. The supporting slope 221 abuts against the guide slope 211 in the Z direction. The forklift connecting frame 100 is a hollow cuboid structure with openings at both ends, and its interior is the positioning channel 110. The pushing mechanism 220 can move in the X direction, and the pressing mechanism 210 can move in the Z direction under the movement of the pushing mechanism 220. The forks can be clamped between the pressing mechanism 210 and the inner top wall of the forklift connecting frame 100. Through the cooperation of the pressing mechanism 210 and the pushing mechanism 220, the lifting tool can be reliably and stably assembled on the forklift forks, thereby ensuring the reliability and efficiency of lifting and transporting materials.

[0053] Specifically, the anti-slip fixing device 200 also includes a transmission mechanism, which includes a rotating rod 230 with external threads along its circumference. The pushing mechanism 220 has a threaded hole 222 along the X direction, and the rotating rod 230 is coaxially inserted and screwed into the threaded hole 222, allowing it to rotate around its own axis. The pushing mechanism 220 is slidably connected to the inner bottom wall of the positioning channel 110 along the X direction. That is, the pushing mechanism 220 can move in the X direction due to the rotation of the rotating rod 230 and the sliding limit effect of its contact with the inner bottom wall of the positioning channel 110.

[0054] Alternatively, in other embodiments, the transmission mechanism may also include a cylinder, the cylinder body of which is disposed on the side of the forklift connecting frame 100, and the telescopic rod of which extends along the X direction to the positioning channel 110 and is connected to the pushing mechanism 220. In this manner, the movement of the pushing mechanism 220 in the X direction can also be achieved.

[0055] More specifically, the anti-slip fixing device 200 also includes a drive mechanism 240. The drive mechanism 240 is mounted on the forklift connecting frame 100, located outside the positioning channel 110, and is drively connected to the rotating rod 230. The drive mechanism 240 is configured to drive the rotating rod 230 to rotate. In this embodiment, the drive mechanism 240 may specifically be a rotary handle, allowing the operator to rotate the rotating rod 230 via the rotary handle.

[0056] Alternatively, in other embodiments, the drive mechanism 240 described above may also be a servo motor or the like, thereby improving the automation level of the process of reliably assembling the forks in the positioning channel 110.

[0057] More specifically, the inner bottom of the positioning channel 110 is provided with a guide groove 120 along the X direction. The pushing mechanism 220 is provided with a guide protrusion 223 on the side facing the inner bottom of the positioning channel 110, and the guide protrusion 223 is slidably disposed in the guide groove 120. Through the above arrangement, the sliding limit of the pushing mechanism 220 in the X direction can be realized.

[0058] Preferably, there are multiple guide grooves 120, which are spaced apart in the Y direction. The pushing mechanism 220 has multiple guide protrusions 223 on its inner bottom side facing the positioning channel 110. These guide protrusions 223 are slidably connected to the guide grooves 120 and correspond one-to-one. In this embodiment, two guide grooves 120 are specifically provided, and correspondingly, two guide protrusions 223 are provided at the bottom of the pushing mechanism 220. This arrangement improves the reliability of the sliding limit of the pushing mechanism 220 in the X direction and the uniformity of the force applied to the pushing mechanism 220.

[0059] More specifically, a protrusion 212 is provided on one side of the pressing mechanism 210 and on the inner wall of the positioning channel 110, while a limiting groove 130 is provided on the other. The limiting groove 130 extends along the Z direction, and the protrusion 212 is slidably connected in the limiting groove 130. In this embodiment, the limiting groove 130 is specifically formed on the inner side wall of the positioning channel 110, and the protrusion 212 is specifically disposed on the side of the pressing mechanism 210. Through the above arrangement, the movement of the pressing mechanism 210 in the Z direction can be guided, ensuring the reliability of the pressing mechanism 210's abutment and positioning against the forks.

[0060] Preferably, there are multiple protrusions 212, which are spaced apart in the Y direction. There are also multiple limiting grooves 130, which are spaced apart in the Y direction. Each protrusion 212 corresponds to and is slidably disposed within a limiting groove 130. This arrangement improves the reliability of the pressing mechanism 210's movement guidance in the Z direction.

[0061] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
