Embodiment one

[0067] In this embodiment, a shore-based container crane dragging device is installed on two adjacent shore-based container cranes. When the trolley of a certain shore-based container crane fails, the shore-based container crane dragging device is used to connect two adjacent shore-based container cranes, and the adjacent shore-based container crane is used to drag the trolley of the shore-based container crane with failure to move, so as to realize safe avoidance of approaching and leaving the ship.

[0068] In this embodiment, as shown in Figure 1 , Figure 3 , Figure 5 The shore-based container crane dragging device includes a first locking module 100 and a second locking module 200. The first locking module 100 and the second locking module 200 are respectively arranged on the adjacent shore-based container cranes. When it is necessary to drag the shore-based container crane with failure, the first locking module 100 and the second locking module 200 are connected.

[0069] In the embodiment, the first locking module 100 comprises a first locking component 110, a plurality of telescopic driving assemblies 120, a rotary driving assembly 130, a connecting assembly and a guide assembly.

[0070] The second locking module 200 comprises a second locking component 210.

[0071] The plurality of telescopic driving assemblies 120 are used to drive the first locking module 100 to extend or retract.

[0072] The rotary driving assembly 130 is used to drive the first locking module 100 to rotate, so as to realize the position locking of the first locking module 100 and the second locking module 200.

[0073] The driving direction of the output end of the telescopic driving assembly 120 is arranged perpendicularly to the driving direction of the output end of the rotary driving assembly 130.

[0074] In the embodiment, the plurality of telescopic driving assemblies 120 are arranged in the same direction with the guide assembly. That is, the plurality of telescopic driving assemblies 120 are arranged in parallel with the guide assembly. The output end of the plurality of telescopic driving assemblies 120 is connected with the first locking module 100, so as to drive the first locking module 100 to extend or retract. And the output end of the telescopic driving assembly 120 drives the first locking module 100 to move along the arrangement direction of the guide assembly.

[0075] In the embodiment, the plurality of telescopic driving assemblies 120 are arranged in the circumferential direction of the guide assembly.

[0076] Specifically, the first locking module 100 is detachably connected with a shore-based container crane traction device, and the second locking module 200 is detachably connected with another adjacent shore-based container crane traction device.

[0077] The plurality of telescopic driving assemblies 120 drive the first locking component 110 to move to the second locking component 210. The rotary driving assembly 130 drives the first locking component 110 to rotate, so as to realize the position locking of the first locking component 110 and the second locking component 210.

[0078] Specifically, the first locking component 110 comprises a lock head. The second locking component comprises a lock hole. The telescopic driving assembly 120 drives the lock head to extend into the lock hole, and the rotary driving assembly 130 drives the lock head to rotate in the lock hole, so as to realize the relative position locking of the two.

[0079] In the embodiment, the second locking module 200 further comprises a second frame body 220, and the end of the second frame body 220 is formed with a lock hole. The lock hole is formed in communication by a cavity 211 formed in the inside of the end of the second frame body 220 and a fourth through hole 212 formed on the side wall of the end of the second frame body 220.

[0080] A plurality of third through holes 221 are circumferentially spaced apart at the end of the second frame 220, and the plurality of third through holes 221 are in communication with the cavity 211, so that an operator can observe the rotating state of the lock head in the lock hole through the third through holes 221.

[0081] In the embodiment, as shown in Figure 2 、 Figure 4 、 Figure 6 、 Figure 8 The first locking module 100 further includes a first frame 160, and the fixed ends of the plurality of telescopic driving assemblies 120 and the fixed ends of the rotary driving assemblies 130 are arranged on the first frame 160.

[0082] Specifically, the telescopic driving assembly 120 is a telescopic oil cylinder, and the rotary driving assembly 130 is a rotary oil cylinder. The fixed end of the telescopic oil cylinder is arranged on the first frame 160, and the fixed end of the rotary oil cylinder is also arranged on the first frame 160.

[0083] The guide assembly includes two guide plates 151 arranged in parallel. The two guide plates 151 are arranged in parallel on the first frame 160. The guide plate 151 is provided with a first through hole 1511.

[0084] The two guide plates 151 are arranged in parallel on the first frame 160. The two first through holes 1511 are coaxially arranged.

[0085] The connecting assembly includes a connecting rod 141. The first end of the connecting rod 141 is connected with the first locking part 110 after sequentially passing through the two first through holes 1511. That is, the lock head is arranged on the first end of the connecting rod 141.

[0086] The second end of the connecting rod 141 is connected with the output end of the telescopic driving assembly 120.

[0087] The telescopic driving assembly 120 drives the connecting rod 141 to move along the two first through holes 1511, so as to drive the lock head to extend or retract.

[0088] Specifically, in order to facilitate the connection of the plurality of telescopic driving assemblies 120 and the connecting rod 141, the connecting assembly further includes a telescopic connecting plate 142.

[0089] The lock head is coaxially arranged with the connecting rod 141.

[0090] In the embodiment, the number of the telescopic driving assemblies 120 is not limited, and the telescopic driving assemblies 120 are arranged at intervals along the circumference of the lock head, especially, the telescopic driving assemblies 120 are evenly distributed along the axis, so that the thrust applied to the lock head is more balanced, and because the telescopic driving assemblies 120 are evenly distributed along the circumference of the connecting rod 141, the circumferential component forces applied to the connecting rod 141 cancel each other out, so that the connecting rod 141 can smoothly move along the two first through holes 1511.

[0091] The connecting rod 141 is arranged at the middle of the telescopic connecting plate 142, and the output ends of the telescopic driving assemblies 120 are connected at intervals along the circumference of the telescopic connecting plate 142.

[0092] The number of the telescopic driving assemblies 120 is not limited, and in the embodiment, two telescopic driving assemblies 120 are taken as an example for illustration.

[0093] Correspondingly, the telescopic connecting plate 142 adopts a rhombus structure. The second end of the connecting rod 141 is connected at the center of the telescopic connecting plate 142. The output ends of the two telescopic driving assemblies 120 are connected at two opposite ends of the telescopic connecting plate 142. The output ends of the two telescopic driving assemblies 120 drive the connecting rod 141 to move through the telescopic connecting plate 142, so as to drive the extension and retraction of the lock head.

[0094] In the embodiment, in order to ensure the structural strength of the two guide plates 151, a reinforcing portion 152 is arranged at the connection between the guide plate 151 and the first frame body 160.

[0095] In the embodiment, as shown in Figure 7 The connecting assembly further includes a rotating connecting plate 143. The output end of the rotating driving assembly 130 is connected with the rotating connecting plate 143, and the rotating driving assembly 130 drives the connecting rod 141 to rotate through the rotating connecting plate 143.

[0096] Specifically, a second through hole 1431 is formed in the rotating connecting plate 143.

[0097] The second through hole 1431 is sleeved on the second end of the connecting rod 141. Specifically, the second through hole 1431 has the same cross section as the connecting rod 141. The second through hole 1431 is sleeved on the connecting rod 141. Because the rotating connecting plate 143 needs to drive the connecting rod 141 to rotate, the second through hole 1431 can adopt a non-circular hole.

[0098] In some other embodiments, the second through hole 1431 can also adopt a circular hole, and the rotating connecting plate 143 is in interference fit with the connecting rod 141, so that the rotating connecting plate 143 can drive the connecting rod 141 to rotate.

[0099] The first locking module 100 and the second locking module 200 are arranged on the adjacent sides of the trolleys of the adjacent shore-based container cranes.

[0100] The first locking module 100 and the second locking module 200 are arranged on the adjacent sides of the trolleys of the adjacent shore-based container cranes.

[0101] In the embodiment, when the shore-based container crane is close to the adjacent shore-based container crane to the target distance, the moving shore-based container crane needs to be prompted to stop moving, and therefore, the shore-based container crane towing device further comprises a control module and a detection module.

[0102] In the embodiment, the detection module comprises a first detection assembly, a second detection assembly and a third detection assembly.

[0103] The first detection assembly comprises a distance measuring sensor and a first detection component. Specifically, the distance measuring sensor is installed on the shore-based container crane, and the first detection component can be a detection plate arranged at a position corresponding to the distance measuring sensor on the adjacent shore-based container crane.

[0104] The distance measuring sensor and the first detection component can measure the distance between the two adjacent shore-based container cranes.

[0105] The distance measuring sensor is electrically connected to the control module, and the control module transmits a signal to the moving shore-based container crane, so that the moving shore-based container crane stops moving.

[0106] After the shore-based container crane moves to the target position, the telescopic driving assembly 120 drives the lock head to extend out. In order to detect whether the lock head extends to the target position, the second detection assembly comprises a first proximity switch 311 and a second detection component 312. The first proximity switch 311 is electrically connected to the control module.

[0107] The first proximity switch 311 is arranged opposite to the second detection component 312. When the second detection component 312 moves to a distance value range set by the first proximity switch 311, the first proximity switch 311 sends a signal to the control module, so as to prompt the lock head to extend to the target position.

[0108] Specifically, the first proximity switch 311 is installed on the first frame body 160, and the second detection component 312 is arranged on the telescopic connecting plate 142. The second detection component 312 is arranged opposite to the position of the telescopic connecting plate 142. When the second detection component 312 moves with the telescopic driving assembly 120, when the second detection component 312 moves to the target distance of the first proximity switch 311, the first proximity switch 311 sends a signal to the control module, so that the telescopic driving assembly 120 stops moving.

[0109] At this time, the lock head extends into the target position in the lock hole, and then the rotary driving assembly 130 drives the connecting rod 141 to rotate. In order to detect that the lock head rotates to the target angle relative to the lock hole, the third detection assembly includes a third proximity switch 321, a fourth proximity switch 322 and a fourth detection component 323. The third proximity switch 321 and the fourth proximity switch 322 are arranged on the first frame body 160 along the circumference of the connecting rod 141.

[0110] The included angle between the third proximity switch 321 and the fourth proximity switch 322 relative to the connecting rod 141 is the target angle of the lock head rotating to the locking position relative to the lock hole.

[0111] Specifically, the target angle of the lock head rotating relative to the lock hole is 90°. Therefore, the included angle between the third proximity switch 321 and the fourth proximity switch 322 relative to the connecting rod 141 is 90°.

[0112] The fourth detection component 323 is arranged at the hinge between the connecting rod 141 and the rotary connecting plate 143.

[0113] The fourth detection component 323 is arranged opposite to the third proximity switch 321 and the fourth proximity switch 322.

[0114] The third proximity switch 321 and the fourth proximity switch 322 are electrically connected to the control module.

[0115] When the lock head is not rotated after being inserted into the lock hole, the third proximity switch 321 is arranged opposite to the fourth detection component 323, and the fourth detection component 323 triggers the third proximity switch 321.

[0116] When the lock head rotates to the target angle relative to the lock hole, the fourth proximity switch 322 is arranged opposite to the fourth detection component 323, and the fourth detection component triggers the fourth proximity switch 322.

[0117] In the embodiment, after the fourth detection component 323 moves to the detection distance of the third proximity switch 321, the third proximity switch 321 is triggered, the third proximity switch 321 feeds back a signal to the control module, and the relative angle of the lock head and the lock hole is prompted; the rotary driving assembly 130 drives the connecting rod 141 to rotate, and when the connecting rod 141 rotates to the fourth proximity switch 322 moving to the detection distance of the fourth detection component 323, the fourth proximity switch 322 is triggered, the fourth proximity switch 322 feeds back a signal to the control module, the lock head has been rotated to the target angle relative to the lock hole, and the lock head and the lock hole are locked.

[0118] After the lock head and the lock hole are locked, the trolley of the shore-based container crane is started, so that the adjacent shore-based container crane is dragged to move along the track of the shore. When the two move to the target position, the rotary driving assembly 130 drives the connecting rod 141 to rotate reversely, the third proximity switch 321 rotates to the detection distance of the fourth detection component 323, the third proximity switch 321 is triggered, and the third proximity switch 321 feeds back a signal to the control module, prompting that the lock head and the lock hole are unlocked.

[0119] At this time, the lock head is moved out of the lock hole and retracted by the telescopic driving assembly 120. In order to prompt the target position of the retraction of the lock head, the second detection assembly further comprises a second proximity switch 313 and a third detection component 314.

[0120] In the embodiment, the second proximity switch 313 is arranged on the inner wall of the end of the first frame body 160 away from the lock head. The third detection component 314 is arranged on the telescopic connecting plate 142, and the third detection component 314 and the second detection component 312 are arranged on the opposite sides of the telescopic connecting plate 142, respectively. The second proximity switch 313 is arranged opposite to the third detection component 314.

[0121] When the telescopic connecting plate 142 is retracted to the third detection component 314 moving to the detection range of the second proximity switch 313 by the telescopic driving assembly 120, the second proximity switch 313 is triggered, and the second proximity switch 313 feeds back a signal to the control module, prompting that the lock head has been retracted to the target position.

[0122] At this time, the shore-based container crane dragging device returns to the original position. Embodiment Two

[0123] In the embodiment, a control method of a shore-based container crane dragging device is involved. When the trolley of the shore-based container crane fails, the following steps are adopted for emergency dragging:

[0124] S1: In the process of moving towards the malfunctioning shore-based container crane, the first detection component triggers the distance measuring sensor, the distance measuring sensor feeds back signals to the control module, the control module prompts that the shore-based container crane has moved to the target position, and the shore-based container crane stops moving;
