Description

Technical Field

[0001] This application relates to the field of four-hook lifting chains, and more specifically, to a self-balancing four-hook lifting chain. Background Technology

[0002] A four-hook lifting chain, also known as a four-chain hook or four-legged hook, consists of four chains of the same length and four hooks. It is connected to a crane via lifting rings and is suitable for lifting boxed, bundled, and other cargoes. It is especially widely used in port loading and unloading. Its four-hook design can automatically balance the center of gravity of the cargo, reduce the risk of tilting, and ensure a safe and stable lifting process.

[0003] However, the existing four-hook lifting chains still have the following shortcomings in use: the length of the existing four-hook lifting chains cannot be adjusted. When using four-hook lifting chains to lift non-parallelogram objects, some of the chains cannot be fully extended after being lifted, causing the lifted object to tilt. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a self-balancing four-hook lifting chain, which aims to improve the situation where, when lifting non-parallelogram objects, part of the chain cannot be fully extended after being lifted, causing the lifted object to tilt.

[0005] This application provides a self-balancing four-hook chain, including four hooks. The outer surface of the four hooks is provided with an adjustment mechanism for adjusting the length of the chain, and the outer surface of the four hooks is provided with a storage mechanism for storing excess chain.

[0006] The adjustment mechanism includes four chains. One end of each chain is sleeved on one end of a four-legged hook, and the other end of the chain is sleeved on a mounting base. A first mounting component and a second mounting component are connected to one side of the mounting base.

[0007] In one specific implementation, both the first mounting component and the second mounting component have placement slots on their tops.

[0008] In the above implementation process, by setting the placement groove, a part of the four-legged hook chain can be placed above the placement groove, and after the chain is straightened, a certain support force can be provided by the first mounting part and the second mounting part.

[0009] In one specific implementation, a positioning hole is provided on one side of the first mounting component.

[0010] In the above implementation process, by setting the positioning hole, a portion of the four-legged hook chain can be limited between the first mounting part and the second mounting part.

[0011] In one specific implementation, a first housing is connected to one side of the second mounting member, a movable member is slidably connected inside the first housing, a positioning member is connected to one side of the movable member, and one end of the positioning member passes through the second mounting member and is movably inserted into the positioning hole.

[0012] In the above implementation process, by setting the moving part, the movement of the moving part can be controlled to drive the positioning part to move, thereby controlling whether the positioning part is inserted into the positioning hole. When the positioning part penetrates a part of the four-legged hook chain and is inserted into the positioning hole, a part of the four-legged hook chain can be limited, thereby shortening the effective length of the four-legged hook chain to deal with non-parallelogram objects.

[0013] In one specific implementation, a crossbar is connected to the other side of the movable component, and the other end of the crossbar passes through the first housing and is connected to a pull plate.

[0014] In the above implementation process, by setting up the pull plate, the crossbar can be moved by pulling the pull plate, which in turn can drive the moving parts to move.

[0015] In one specific implementation, a spring is fitted onto the outer surface of the crossbar.

[0016] In the above implementation process, by setting the spring, the elastic potential energy released by the spring can prevent the moving part from moving randomly when the moving part is not moved by external force, and keep the positioning part inserted into the positioning hole.

[0017] In one specific implementation, the storage mechanism includes a second housing connected to one side of the mounting base.

[0018] In the above implementation process, by setting up the second housing, the invalid part of the four-legged hook chain after it is limited by the positioning component can be put into the interior of the second housing for storage.

[0019] In one specific implementation, a clamping plate is slidably connected inside the second housing.

[0020] In the above implementation process, the clamping plate can prevent the invalid part from swaying randomly when the four-legged hook moves as a whole.

[0021] In one specific implementation, a screw is rotatably connected to one side of the clamping plate, one end of the screw penetrates through the second housing, and the outer surface of the screw is threadedly connected to one side of the second housing.

[0022] In the above implementation process, by setting the screw, when the screw rotates, one end of the screw can be driven to move into the interior of the second housing, thereby driving the clamping plate to move and preventing the four-legged hook chain from being clamped inside the second housing.

[0023] In one specific implementation, an adjustment knob is connected to one end of the screw.

[0024] In the above implementation process, by adjusting the knob settings, the screw can be rotated by rotating the adjustment knob.

[0025] Compared with the prior art, the beneficial effects of this application are as follows: By setting the adjustment mechanism and the storage mechanism, the movement of the moving part can be controlled to drive the movement of the positioning part, thereby controlling whether the positioning part is inserted into the positioning hole. When the positioning part penetrates a part of the four-legged hook chain and is inserted into the positioning hole, a part of the four-legged hook chain can be limited, thus shortening the effective length of the four-legged hook chain. This is used to deal with non-parallelogram objects, so that they can be lifted in a balanced state. After the four-legged hook chain is limited by the positioning part, the ineffective part is stored inside the second housing, preventing the ineffective part from swaying randomly when the four-legged hook moves as a whole. This solves the problem that when lifting non-parallelogram objects, part of the chain cannot be fully extended after being lifted, causing the lifted object to tilt. Attached Figure Description

[0036] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0037] Please see Figure 1 This application provides a self-balancing four-hook lifting chain, including four hooks 1.

[0038] Please see Figure 1 and Figure 2 The outer surface of the four-legged hook 1 is provided with an adjustment mechanism 2 for adjusting the length of the hanging chain, and the outer surface of the four-legged hook 1 is provided with a storage mechanism 3 for storing excess hanging chain.

[0039] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The adjustment mechanism 2 includes a chain 201, and there are four sets of chains 201. One end of the chain 201 is sleeved on one end of the four-legged hook 1, and the other end of the chain 201 is sleeved on a mounting base 202. A first mounting component 203 and a second mounting component 204 are connected to one side of the mounting base 202.

[0040] In the specific configuration, the top of the first mounting component 203 and the second mounting component 204 are both provided with a placement groove 206. The placement groove 206 allows a portion of the four-legged hook 1 lifting chain to be placed above the placement groove 206, and provides a certain support force through the first mounting component 203 and the second mounting component 204 after the lifting chain is straightened.

[0041] In a specific configuration, a positioning hole 205 is provided on one side of the first mounting component 203. The positioning hole 205 allows a portion of the chain of the four-legged hook 1 to be positioned between the first mounting component 203 and the second mounting component 204.

[0042] In a specific configuration, a first housing 207 is connected to one side of the second mounting component 204. A movable component 2011 is slidably connected inside the first housing 207. A positioning component 2012 is connected to one side of the movable component 2011. One end of the positioning component 2012 passes through the second mounting component 204 and is movably inserted into the positioning hole 205. By controlling the movement of the movable component 2011, the positioning component 2012 can be moved, thereby controlling whether the positioning component 2012 is inserted into the positioning hole 205. When the positioning component 2012 passes through a part of the four-legged hook 1 chain and is inserted into the positioning hole 205, a portion of the four-legged hook 1 chain can be limited, thus shortening the effective length of the four-legged hook 1 chain to accommodate non-parallelogram objects.

[0043] In a specific configuration, a crossbar 208 is connected to the other side of the movable component 2011. The other end of the crossbar 208 passes through the first housing 207 and is connected to a pull plate 209. By setting the pull plate 209, the crossbar 208 can be moved by pulling the pull plate 209, which in turn moves the movable component 2011.

[0044] In a specific configuration, a spring 2010 is fitted on the outer surface of the crossbar 208. The spring 2010 prevents the moving part 2011 from moving arbitrarily by releasing its elastic potential energy when the moving part 2011 is not moved by an external force, thus keeping the positioning part 2012 inserted into the positioning hole 205.

[0045] In a specific configuration, the storage mechanism 3 includes a second housing 301, which is connected to one side of the mounting base 202. The second housing 301 allows the invalid portion of the chain of the four-legged hook 1 after it is limited by the positioning member 2012 to be stored inside the second housing 301.

[0046] In a specific configuration, a clamping plate 302 is slidably connected inside the second housing 301. The clamping plate 302 prevents the invalid part from swaying randomly when the four-legged hook 1 moves as a whole.

[0047] In the specific configuration, a screw 303 is rotatably connected to one side of the clamping plate 302. One end of the screw 303 passes through the second housing 301, and the outer surface of the screw 303 is threaded to one side of the second housing 301. The screw 303 can be rotated to move one end of the screw 303 into the interior of the second housing 301, thereby moving the clamping plate 302 and preventing the four-legged hook 1 from being clamped by the chain inside the second housing 301.

[0048] In a specific configuration, one end of the screw 303 is connected to an adjustment knob 304. By adjusting the knob 304, the screw 303 can be rotated.

[0049] The working principle of this self-balancing four-hook lifting chain is as follows: When using the self-balancing four-hook lifting chain to lift non-parallelogram objects, pulling the pull plate 209 moves the crossbar 208, which in turn moves the moving part 2011. This causes the positioning part 2012 to disengage from the positioning hole 205, shortening the effective length of part of the four-hook lifting chain. The portion of the four-hook lifting chain to be shortened is placed between the first mounting part 203 and the second mounting part 204. Then, the positioning part 2012 passes through a portion of the four-hook lifting chain and is inserted into the positioning hole 205, further shortening the effective length of the four-hook lifting chain to cope with... For non-parallelogram objects, the suspension chain is kept in a balanced state. After the four-legged hook 1 chain is limited by the positioning component 2012, the invalid part of the four-legged hook 1 chain is stored inside the second housing 301. By operating the adjustment knob 304, the screw 303 is rotated, which causes the clamping plate 302 to move inside the second housing 301, clamping the invalid part. This prevents the invalid part from swaying randomly when the four-legged hook 1 moves as a whole, thus solving the problem that when lifting non-parallelogram objects, part of the chain cannot be fully extended after being lifted, causing the lifted object to tilt.

[0050] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
