Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and particularly to a lifting tool. Background Art

[0002] A container ship, also known as a container carrier, is a ship specifically designed to carry international standard containers. The container columns of a container ship are important components that support the stacking of containers. The installation quality of the container columns is directly related to the stability and safety of container stacking. Therefore, during the installation process, it is necessary to continuously position and adjust the position of the container columns to ensure that they fit with the positioning holes or bases on the ship.

[0003] Due to the constraints of the self-structure and weight of the container columns, during the installation and handling process, construction workers cannot rely solely on manpower for handling and installation adjustment and must rely on lifting machinery.

[0004] To save costs, during the prefabrication stage of the container columns, a small-tonnage truck crane is generally used for lifting and handling. However, due to the use of a small-tonnage truck crane, it requires a large construction site, and it cannot move quickly after each lifting. During the installation stage of the container columns, due to the limited space on the ship's deck, a small-tonnage truck crane cannot be placed, and due to the limited height of the ship, only a large-tonnage truck crane can be used to lift and install the container columns on the ground. This not only occupies the limited ground lifting resources but also has low construction efficiency and affects the shipbuilding efficiency.

[0005] Therefore, there is an urgent need for a lifting tool to solve the above problems. Summary of the Invention

Through the forklift connecting frame 100 and the lifting connection mechanism 300, the connection between the fork of the forklift and the material to be lifted such as a box column can be realized, so as to realize the lifting and transportation of the material to be lifted by means of the forklift, and the occupation of ground lifting resources can be reduced. The anti-slip fixing device 200 is arranged in the positioning channel 110 and can fix the fork of the forklift in the positioning channel 110 to ensure the lifting stability and reliability of the material to be lifted.

[0047] Figure 2 Shown Figure 1 A partial enlarged view of the structure marked A in Figure 3 A schematic exploded view of the movable connection mechanism provided by an embodiment of the present invention is shown.

The hook assembly 320 is connected to one end of the connecting cable 310 away from the connecting ear 140. The hook assembly 320 is configured to connect the material to be lifted. In this embodiment, the connecting cable 310 can specifically be selected as a chain or the like. The hook assembly 320 can specifically be selected as a hook provided with an anti-detachment buckle in the prior art.

The movable connection mechanism 330 includes a rotating shaft 331, a first connecting member 332, and a second connecting member 333. The rotating shaft 331 is disposed at the top of the hook assembly 320. Both the first connecting member 332 and the second connecting member 333 are connected to the rotating shaft 331 and can swing about the rotating shaft 331. The first connecting member 332 and the second connecting member 333 are snap-connected to form a connecting channel 334, and the connecting cable 310 is passed through and connected in the connecting channel 334. Through the swingable connection of the first connecting member 332 and the second connecting member 333 relative to the hook assembly 320, the lifting flexibility of the material to be lifted can be improved.

[0050] More specifically, two mounting seats 335 are spaced apart at the top of the hook assembly 320. Both ends of the rotating shaft 331 are respectively connected to a mounting seat 335, so that a certain distance is left between the rotating shaft 331 and the top of the hook assembly 320. Both the first connecting member 332 and the second connecting member 333 are in an arc structure. Taking the first connecting member 332 as an example, a hollow cylindrical connecting portion is integrally formed at the bottom end thereof. The rotating shaft 331 passes through the hollow cylindrical connecting portion, and there is a gap between the circumferential side of the rotating shaft 331 and the inner wall of the hollow cylindrical connecting portion to realize the rotatable connection between the first connecting member 332 and the rotating shaft 331.

[0051] More specifically, the movable connection mechanism 330 further includes a bolt 336 and a nut 337. A first bolt mounting ear plate is integrally formed at the top of the first connecting member 332, and a second bolt mounting ear plate is integrally formed at the top of the second connecting member 333. The bolt 336 sequentially passes through the second bolt mounting ear plate and the first bolt mounting ear plate, and the nut 337 is screwed onto the bolt 336. The second bolt mounting ear plate and the first bolt mounting ear plate are clamped between the nut 337 and the head of the bolt 336.

[0052] Figure 4 Partial structural schematic diagrams of the anti-slip fixing device and the forklift connecting frame provided by the embodiments of the present invention are shown; Figure 5 The structural schematic diagram of the pushing mechanism provided by the embodiments of the present invention is shown.

The pushing mechanism 220 can move along the X direction, and the pressing mechanism 210 can move along the Z direction driven by the movement of the pushing mechanism 220, and the fork 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 easily and stably assembled on the fork of the forklift, thereby ensuring the reliability and efficiency of the lifting and transportation of the materials to be lifted.

In this embodiment, the driving mechanism 240 can be a rotating handle, and the operator can drive the rotating rod 230 to rotate through the rotating handle.

[0056] Alternatively, in other embodiments, the driving mechanism 240 may also be a servo motor, etc., so as to improve the degree of automation of the process of reliably assembling the fork in the positioning channel 110 .

[0057] More specifically, a guiding groove 120 is formed in the inner bottom of the positioning channel 110 along the X direction. A guiding projection 223 is provided on one side of the pushing mechanism 220 facing the inner bottom of the positioning channel 110, and the guiding projection 223 is slidably disposed in the guiding groove 120.

A plurality of guiding projections 223 are provided on one side of the pushing mechanism 220 facing the inner bottom of the positioning channel 110, and the guiding projections 223 are correspondingly and slidably connected to the guiding grooves 120. In this embodiment, specifically two guiding grooves 120 are formed, and correspondingly, two guiding projections 223 are provided at the bottom of the pushing mechanism 220. Through the above arrangement, the reliability of the sliding limit of the pushing mechanism 220 in the X direction and the uniformity of the force received by the pushing mechanism 220 can be improved.
