Description

Technical Field

[0001] This utility model belongs to the field of container spreader technology, and specifically relates to an automated linkage control container spreader unit. Background Technology

[0002] A shipping container is a large cargo container with certain strength, rigidity, and specifications, specifically designed for repeated use. Using containers for cargo transport allows for direct loading at the shipper's warehouse and unloading at the consignee's warehouse. When changing vehicles or ships en route, the goods do not need to be removed from the container; the container's location can be directly transferred. The greatest advantage of containers lies in their standardization and the resulting comprehensive transportation system. This standardization allows for the transport of massive cargo weighing tens of tons, and on this basis, a multimodal logistics system integrating ships, ports, shipping routes, highways, transit stations, bridges, and tunnels can be gradually realized globally.

[0003] Currently, container spreaders consist of a spreader and four lifting chains. The four chains extend downwards from the four corners of the spreader, and hooks are fixed to the ends of the chains. When a container needs to be lifted, the operator fixes the four hooks to the lifting positions at the four corners of the container. However, the operation of fixing the spreader to the top of the container requires manual operation and cannot be automated. This method is unsafe for operators and is labor-intensive, time-consuming, inefficient, and disrupts the normal lifting process. Utility Model Content

[0004] The main objective of this invention is to provide an automated, linked control container spreader unit. Each first lifting vehicle component includes: a locking head; and corner pieces located at two corners on one side of the container's top, with the two locking heads extending into their respective corner pieces. A drive unit drives a linkage assembly to rotate the two locking heads, while simultaneously pulling a reset component, thus releasing the two locking heads from their corresponding corner pieces. Simultaneously, the drive unit resets, driving the linkage assembly to rotate and reset the two locking heads, ensuring they remain locked relative to their corresponding corner pieces. By employing this solution, the automatic locking and unlocking of the locking heads relative to the corner pieces by the drive unit eliminates the need for manual locking and unlocking operations. This makes the operation of this invention time-saving, labor-saving, and highly efficient, without affecting the normal lifting procedure.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a rotatable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] A shipping container is a large cargo container with certain strength, rigidity, and specifications, specifically designed for repeated use. Using containers for cargo transport allows for direct loading at the shipper's warehouse and unloading at the consignee's warehouse. When changing vehicles or ships en route, the goods do not need to be removed from the container; the container's location can be directly transferred. The greatest advantage of containers lies in their standardization and the resulting comprehensive transportation system. This standardization allows for the transport of massive cargo weighing tens of tons, and on this basis, a multimodal logistics system integrating ships, ports, shipping routes, highways, transit stations, bridges, and tunnels can be gradually realized globally.

[0032] Currently, container spreaders consist of a spreader and four lifting chains. The four chains extend downwards from the four corners of the spreader, and hooks are fixed to the ends of the chains. When a container needs to be lifted, the operator fixes the four hooks to the lifting positions at the four corners of the container. However, the operation of fixing the spreader to the top of the container requires manual operation and cannot be automated. This method is unsafe for operators and is labor-intensive, time-consuming, inefficient, and disrupts the normal lifting process.

[0033] Example 1

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in Embodiment 1 of this utility model, an automated linkage control container spreader unit is provided, which includes: a single-sided track 110, two first lifting vehicle assemblies 120 respectively installed at both ends of the single-sided track 110, a linkage assembly 130 for linking the two first lifting vehicle assemblies 120, a driving component 140 for driving the linkage assembly 130, and a reset component 150 for driving the linkage assembly 130 to reset.

[0035] Each of the first lifting vehicle components 120 includes: a locking head 121, and corner pieces 160 provided at two corners on one side of the top of the container, with the two locking heads 121 extending into the corresponding two corner pieces 160 respectively;

[0036] While the driving component 140 drives the linkage component 130 to rotate the two locking components 121, the linkage component 130 also drives the reset component 150 to stretch, so that the two locking components 121 are unlocked relative to their corresponding corner components 160.

[0037] While the driving component 140 is reset, the reset component 150 resets and drives the linkage component 130 to rotate and reset the two locking components 121, so that the two locking components 121 remain locked relative to their corresponding corner components 160.

[0038] In this utility model, the aforementioned automated linkage control container spreader includes two automated linkage control container spreader units, which are respectively located on both sides of the top of the container. Corner pieces 160 are located at the four corners of the top sides of the container. The container is lifted by the cooperation of the two automated linkage control container spreader units and the corner pieces 160. By adopting this scheme, the linkage component 130 can be automatically driven by the drive component 140 to lock and unlock the locking head component 121 relative to the corner pieces 160, thus avoiding manual locking and unlocking operations. This makes the operation of this utility model time-saving, labor-saving, and highly efficient, without affecting the normal lifting procedure.

[0039] like Figure 5 and Figure 6 As shown, in order to drive the lock cylinder 121 to rotate, the linkage assembly 130 includes: two linkage rods 131 that are respectively linked to the corresponding lock cylinder 121. Each lock cylinder 121 includes: a lock block 1211 and a drive shaft 1212 extending upward from the lock block 1211. Each linkage rod 131 has teeth 1311 on one side, and each drive shaft 1212 has a gear 12121 near one end of the corresponding linkage rod 131. The gear 12121 meshes with the teeth 1311, so that while driving the linkage rod 131 to rotate in conjunction with the corresponding drive shaft 1212, it also drives the lock block 1211 corresponding to the drive shaft 1212 to rotate.

[0040] In order to drive the linkage rod 131 to move, the linkage assembly 130 further includes: a guide head 132, a first guide rail 133, a reversing pulley 134, a first connecting cable 135, and a second connecting cable 136. Each of the first hoisting vehicle assemblies 120 further includes: a hoisting vehicle body 122.

[0041] The first guide rail 133 is installed on the crane body 122 along the length direction of the crane body 122. The guide head 132 is provided with a first guide groove 1321. After the first guide rail 133 is embedded in the first guide groove 1321, the guide head 132 can slide along the direction of the first guide rail 133.

[0042] The first connecting cable 135 elastically connects one end of two adjacent linkage rods 131. The second connecting cable 136 elastically connects the other end of one of the linkage rods 131 and the guide head 132 through the reversing pulley 134. The reset member 150 connects the other end of the other linkage rod 131 to the crane body 122 corresponding to the other linkage rod 131. Since the first connecting cable 135 and the second connecting cable 136 will deform after long-term use, the rotation angle of the locking head 121 will be inaccurate. The connection method of the first connecting cable 135 and the second connecting cable 136 with other components is changed to elastic connection. When elastic connection is used, the first connecting cable 135 and the second connecting cable 136 can retract after linkage is completed, so that the length of the first connecting cable 135 and the second connecting cable 136 remains unchanged, which can make the rotation angle of the locking head 121 accurate.

[0043] The driving component 140 drives the guide head 132 to move along the length direction of the crane body 122. The guide head 132 drives the second connecting cable 136 to move in the opposite direction to the guide head 132 through the reversing pulley 134, which links the two linkage rods 131 and the first connecting cable 135. The reset component 150 is in a stretched state.

[0044] While the driving component 140 is reset, the reset component 150 is also reset. The reset component 150 resets in conjunction with the two linkage rods 131 and the first connecting cable 135. One of the linkage rods 131 drives the second connecting cable 136 to move in the opposite direction through the reversing pulley 134 and the guide head 132 to reset.

[0045] In this utility model, the driving component 140 is preferably a cylinder, but is not limited to this utility model. The driving component 140 can realize reciprocating motion to drive the guide head 132 to move, and this utility model does not limit it. The reset component 150 is preferably a reset spring, but is not limited to this utility model. The reset component 150 can realize reciprocating motion of stretching and contraction, and this utility model does not limit it.

[0046] To prevent the reset component 150, the first connecting cable 135, and the second connecting cable 136 from damaging the linkage rod 131 during shaking, the linkage rod 131 includes: a rod body 1312 and connectors 1313 rotatably disposed at both ends of the rod body 1312; the teeth 1311 are disposed on the side of the rod body 1312 near the gear 12121, and the connectors 1313 are used to connect the reset component 150, the first connecting cable 135, and the second connecting cable 136. Since the connectors 1313 and the rod body 1312 are rotatably connected, even if the reset component 150, the first connecting cable 135, and the second connecting cable 136 shake up and down, the rod body 1312 will rotate through the connectors 1313 and the rod body 1312, thereby preventing the rod body 1312 from disengaging from the gear 12121.

[0047] To guide the sliding of the rod body 1312, the linkage rod 131 further includes: a second guide rail 1314, which is located at the bottom of the rod body 1312; the hoisting vehicle body 122 is provided with a guide slider 1221 at a position corresponding to the second guide rail 1314, and the guide slider 1221 is provided with a second guide groove 12211. After the second guide rail 1314 is embedded in the second guide groove 12211, it can slide along the direction of the second guide groove 12211, thereby guiding the movement direction of the rod body 1312 through the cooperation of the second guide rail 1314 and the second guide groove 12211.

[0048] To prevent the locking block 1211 from colliding with the corner piece 160, the first hoisting vehicle assembly 120 further includes a drive shaft seat 123. After the drive shaft seat 123 is installed at the bottom of the hoisting vehicle body 122, the drive shaft seat 123 is also sleeved on the outside of the drive shaft 1212. The length of the cross-section of the drive shaft seat 123 is greater than the length of the cross-section of the locking block 1211, and the width of the cross-section of the drive shaft seat 123 is greater than the width of the cross-section of the locking block 1211. This is to prevent the locking block 1211 from colliding with the corner piece 160 when the drive shaft seat 123 and the locking block 1211 simultaneously extend into and out of the corner piece 160. Furthermore, the length of the cross-section of the locking block 1211 is greater than the width of the cross-section of the drive shaft seat 123, so that when the locking block 1211 rotates to be perpendicular to the drive shaft seat 123, the locking block 1211 can lock the corner piece 160.

[0049] To enable the automated linkage control container spreader unit to also adapt to another smaller container, the automated linkage control container spreader unit further includes: two second lifting vehicle assemblies 170, which are installed on the single-sided track 110 and located inside the two first lifting vehicle assemblies 120; the two second lifting vehicle assemblies 170 are linked together, and each of the two second lifting vehicle assemblies 170 is linked with its adjacent first lifting vehicle assembly 120, and the bottom height of the two second lifting vehicle assemblies 170 is higher than the bottom height of the two first lifting vehicle assemblies 120, thereby avoiding collisions between the two second lifting vehicle assemblies 170 and the top of the larger container when lifting a larger container, thus affecting the service life of the two second lifting vehicle assemblies 170.

[0050] Example 2

[0051] like Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, in Embodiment 2 of this utility model, an automated linkage control container spreader unit is provided. The structure of the single-sided track 110, the first lifting vehicle assembly 120, the second lifting vehicle assembly 170, the drive component 140, the reset component 150, and the corner component 160 in Embodiment 2 is mostly the same as that in Embodiment 1. The difference between Embodiment 2 and Embodiment 1 is that the structure of the linkage component 230 is different, the linkage structure between the linkage component 230 and the first lifting vehicle assembly 220 and the second lifting vehicle assembly 270 is different, and the installation structure of the reset component 250 is different. In Embodiment 2 of this utility model, since the linkage structure between the linkage component 230 and the first lifting vehicle assembly 220 and the second lifting vehicle assembly 270 is different from that in Embodiment 1, the locking component 221 in Embodiment 2 is also different from the locking component 121 in Embodiment 1.

[0052] In Embodiment 2, in order to drive the locking block 2211 to rotate, each locking head 221 includes: a locking block 2211 and a driving shaft 2212 extending upward from the locking block 2211. The linkage assembly 230 includes: a linkage shaft 231 and a rotation reversing member 232 that links each driving shaft 2212 and the linkage shaft 231. The rotation of the linkage shaft 231 drives the two rotation reversing members 232 to rotate the two driving shafts 2212 that are linked to the two rotation reversing members 232 respectively. The rotation of the two driving shafts 2212 drives the locking block 2211 that corresponds to the two driving shafts 2212 to rotate respectively.

[0053] To drive the linkage shaft 231 to rotate and reset, the first hoisting vehicle assembly 220 further includes: a hoisting vehicle body 222; a lever 2311 is provided at both ends of the linkage shaft 231; a driving member 240 is disposed on one side of the lever 2311 at one end of the linkage shaft 231; and a resetting member 250 is sandwiched between the lever 2311 at the other end of the linkage shaft 231 and the hoisting vehicle body 222. While the driving member 240 drives one side of the lever 2311 at one end of the linkage shaft 231 to rotate the linkage shaft 231, the lever 2311 at the other end of the linkage shaft 231 stretches the resetting member 250. Simultaneously with the resetting of the driving member 240, the resetting member 250 resets, and the resetting member 250 pulls the lever 2311 at the other end of the linkage shaft 231 to rotate and reset the linkage shaft 231.

[0054] In order for the linkage shaft 231 to drive the drive shaft 2212 to rotate, the rotation reversing member 232 includes: a drive arm 2321, a reversing arm 2322, and a connecting arm 2323 that links the drive arm 2321 and the reversing arm 2322.

[0055] One end of the drive arm 2321 is vertically fixed to the linkage shaft 231, and the other end of the drive arm 2321 is provided with a first reversing groove 23211. One end of the reversing arm 2322 is vertically fixed to the drive shaft 2212, and the other end of the reversing arm 2322 is provided with a second reversing groove 23221.

[0056] One end of the connecting arm 2323 is provided with a first rotating shaft 23231. The first rotating shaft 23231 is embedded in the first reversing slide groove 23211 and can slide along the direction of the first reversing slide groove 23211. While the linkage rotating shaft 231 drives the reversing arm 2322 to rotate, in the vertical direction, the reversing arm 2322 drives the first rotating shaft 23231 to slide back and forth in the first reversing slide groove 23211. In the horizontal direction, the driving rotating shaft 1212 drives the connecting arm 2323 to move back and forth.

[0057] The other end of the connecting arm 2323 is provided with a clearance groove 23232. The opening of the clearance groove 23232 is provided with a second rotating shaft 23233. The other end of the reversing arm 2322 extends into the clearance groove 23232 and can slide within the clearance groove 23232. The second rotating shaft 23233 is embedded in the second reversing groove 23221 and can slide along the direction of the second reversing groove 23221. During the forward and backward movement of the connecting arm 2323, the reversing arm 2322 is driven to rotate, which in turn drives the driving shaft 2212 to rotate. While the other end of the reversing arm 2322 slides within the clearance groove 23232, the second rotating shaft 23233 slides back and forth within the second reversing groove 23221.

[0058] The present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and alterations to these embodiments can be made without departing from the principles and spirit of the present invention, and these changes still fall within the protection scope of the present invention.
