Description

Full-automatic container interlocking mechanism

Technical Field

The invention relates to the technical field of container transportation, in particular to a full-automatic container interlocking mechanism.

Background

Container ships have evolved from 3000TEU in the eighties of the last century to 22000TEU today. The ultra-large container ship has large cargo capacity, is less influenced by market freight rate, and has much lower transportation cost than other types of ships and common container ships, so the ultra-large container ship is widely adopted by the modern shipping industry.

The standardized size and sturdy construction of the containers allow multiple containers to be stacked one on top of the other so that they can be easily loaded and unloaded. This design of containers, commonly referred to as international organization for standardization containers, provides good protection for the transported goods during transport and loading and unloading.

Today's transport systems, such as ships, can be loaded with thousands of containers, stacked one on top of the other, to efficiently use the available space. In order to ensure the safety of the loading method in the transportation process, the containers loaded on the ship are connected with at least one adjacent container by means of locks such as bottom locks, bases, automatic locks, intermediate locks, ground reams, pull rods, tighteners and the like, and are bound and fixed with the ship body by taking columns as units. When a ship encounters severe weather in navigation, particularly in stormy weather, the ship is subjected to the action of sea waves and swell, physical states such as pitching, rolling, heaving, bumping, sieving and the like are generated, and a container loaded on a deck can also physically move along with the dynamic state of the ship under the comprehensive action of the external forces. At this time, various locks for fixing the container are likely to start to loose and gap, and even cannot bear the swinging and swinging tension of the container, and the locks are directly broken. If the ship continues to shake, the affected single-row containers may topple over, and further, additional external force is generated to the adjacent rows of containers, and finally, the containers fall into water, which is particularly the case when heavy containers are loaded on the high-rise deck. This places extremely high demands on the strength of the locks that secure the container.

Today, due to the diversity of cargo types, the market in the transportation industry is gradually subdivided, the types of high-value and time-sensitive cargoes are more and more, the transportation time becomes a non-negligible potential transportation cost, and the transportation time cost is gradually an important factor for the cargo owner to choose and consider the transportation mode. Currently, thousands of containers are typically stacked on the same ship. This means that a small reduction in the time spent in each container handling section results in a significant time saving and ultimately an economic benefit. Automation of container locks can undoubtedly greatly reduce the time cost of container transportation.

What is needed for shipping is a quick and efficient loading and unloading of containers, as well as minimizing personnel requirements during the loading and unloading of containers. There is an automatic unlocking and locking of container coupling such as korean 'Kummyung' company, which has developed an automatic twist lock suitable for container trailer and fixing of a ship deck to a container, and which is automatically locked when the container is placed and restored to an inactive state when the container is lifted. However, the twist lock can only realize the connection of two containers longitudinally, and meanwhile, the problem of insufficient safety of container fixation exists. The other full-automatic locks are not provided with container connecting devices for realizing simultaneous locking and unlocking of containers in the longitudinal direction and the transverse direction, and the lack of connection among container columns makes the transportation stability of a container stack lower, and the container falls into water easily in the transportation process to cause great shipping loss.

Detailed Description

For a clearer understanding of technical features, objects and effects of the present invention, a detailed description of embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1 to 4, a fully automatic container interlocking mechanism 100 according to an embodiment of the present invention includes a housing 10, a longitudinal coupling device 20 and a transverse coupling device 30, wherein the longitudinal coupling device 20 is used for coupling two containers in a vertical direction, and the transverse coupling device 30 is used for coupling two containers in a horizontal direction.

The housing 10 is used on the one hand for coupling upper containers and on the other hand for positioning the longitudinal coupling means 20 and the transverse coupling means 30. The housing 10 comprises a housing 11, the housing 11 comprising a long side and a short side, the housing 11 being rotatable into the bottom hole of the upper container corner fitting 201, i.e. into the upper container corner fitting 201 when the long side of the housing 11 is parallel to the long side of the bottom hole of the upper container corner fitting 201, and being rotated 90 ° after the entering to effect a coupling with the upper container.

The longitudinal coupling device 20 comprises a coaxially arranged main shaft 22 and an engagement member 24. The main shaft 22 passes through the middle of the shell 10, and the rotation of the main shaft 22 can not drive the shell 10 to rotate. The engagement member 24 is located below the spindle 22; the engagement member 24 includes a core 241 and a guide 242, the guide 242 being located below the core 241, and the guide 242 being a cone for alignment with the top aperture of the underlying shipping container corner fitting 202; the core 241 has a surface on which are mounted first and second screws 243 and 244 disposed in parallel and spaced apart relation, and the engagement member 24 is coupled to or uncoupled from the lower container by means of the helical paths provided by the top holes of the second and first screws 244 and 243, respectively, which are screwed into or out of the lower container corner fitting 202.

Specifically, the first screw 243 is higher than the second screw 244, and the two screws operate on a principle similar to double-thread screw, so that the screwing-in and screwing-out efficiency can be improved. The first screw 243 includes a first guide surface 2431 at a lower portion and a second guide surface 2432 at an upper portion, the first guide surface 2431 forming a substantially smaller angle with respect to the horizontal than the second guide surface 2432, and a lower tooth deviation angle, which is analogous to threads, is substantially smaller than an upper tooth deviation angle. The second screw 244 includes a third guide surface 2441 at a lower portion and a fourth guide surface 2442 at an upper portion, the third guide surface 2441 forming a substantially smaller angle with respect to the horizontal than the fourth guide surface 2442. During the locking process, the third guiding surface 2441 of the second screw 244 is in first contact with the top aperture of the lower container corner fitting 202, guiding the longitudinal coupling device 20 to rotate clockwise as seen from above downwards, since the small angle of the third guiding surface 2441 to the horizontal plane tends to allow the engagement member 24 to enter the top aperture of the lower container corner fitting. The locked state can be seen in fig. 5. During the unlocking process, the second guiding surface 2432 of the first screw 243 is in contact with the top hole of the corner fitting 202 of the lower container, which is also provided with a screw path, and the longitudinal coupling device 20 is guided to rotate anticlockwise when being observed from top to bottom, because the second guiding surface 2432 is easy to self-lock with a large included angle with the horizontal plane, the vertical upward force applied by the invention is insufficient to enable the engaging member 24 to disengage from the corner fitting when dumping, and the vertical upward force applied by the invention can realize unlocking when unloading the container.

The transverse coupling device 30 comprises a guide disc 31, a crank linkage 32 and a lock 33. The guiding disc 31 is sleeved on the main shaft 22 and is positioned in the shell 10, the guiding disc 31 and the main shaft 22 are driven by friction force, and an arc-shaped notch 311 is formed in the guiding disc 31. The crank link mechanism 32 includes a rod 321, two rods 322, and a slider 323, one end of the rod 321 is hinged to one end of the two rods 322, the other end of the rod 321 is hinged to the slider 323, and the slider 323 is disposed in the arc-shaped notch 311 of the guide plate 31 and can reciprocate in the arc-shaped notch 311. When the guide disk 31 receives a small tangential force of a rod 321, it moves up and down and rotates along with the spindle 22; when receiving a large tangential force of a rod 321, the guide disk 31 moves up and down along with the spindle 22. The first rod 321 and a part of the second rod 322 are always positioned in the shell 10, the second rod 322 can extend out of the shell 10 through the side hole 111 arranged on the shell 10, and further can extend out of the side hole 205 of the upper container corner fitting where the shell 10 is positioned through the side hole 204 of the upper container corner fitting; the locking member 33 is fixed to the other end of the two rods 322 and can be coupled to a side container. The crank link mechanism 32 moves in a horizontal plane along with the movement of the longitudinal connecting device 20, and drives the lock piece 33 to realize connection or disconnection with the side container. In the unlocked state of the transverse coupling device 30, a rod 321 is parallel to the tangential direction of the guiding disc 31; in the locked state of the transverse coupling device 30, a rod 321 rotates to be radially parallel to the guide disc 31.

Specifically, the side container corner fitting side hole 205 is adapted to the lock 33, the side container corner fitting side hole 205 includes an unlock position 206 and a lock position 207, the lock position 207 is located below the unlock position 206, the unlock position 206 has a T-shape, the width of the unlock position 206 is larger than the width of the lock 33, and the width of the lock position 207 is smaller than the width of the lock 33.

As shown in fig. 6-8, the transverse coupling device 30 is locked with the longitudinal coupling device 20 as follows:

when the longitudinal connecting device 20 is locked downwards, forward rotation is generated, the process sliding block 323 and the arc notch 311 do not have relative movement, so that the first rod 321 gradually turns to the diameter direction of the guide disc 31 from the tangential direction of the guide disc 31, the movement process of the first rod 321 provides power for the second rod 322 to extend out of the shell 10, the upper side hole 111 of the shell 10 enables the second rod 322 to move only along the connecting line direction of the second rod 322 and the upper container corner fitting side hole 204, the second rod 322 extends out of a certain length and then the locking piece 33 enters the unlocking position 206 of the side container corner fitting side hole 205, at the moment, the second rod 322 is restrained to a certain extent, the acting force of the first rod 321 on the guide disc 31 along the tangential direction of the guide disc 31 is larger, the guide disc 31 only continues to move downwards along with the axial direction, and the locking piece 33 continues to move downwards into the locking position 207 of the side container corner fitting side hole 205, so that locking is realized.

As shown in fig. 9-11, the transverse coupling device 30 is unlocked with the longitudinal coupling device 20 as follows:

the upward unlocking of the longitudinal coupling device 20 results in a reverse rotation, the lock 33 is still at the locking position 207 of the side container corner fitting side hole 205 for a period of time before the lock moves upwards gradually towards the unlocking position 206, the first rod 321 and the second rod 322 keep completely consistent with the diameter direction of the guide disc 31, the sliding block 323 slides in the arc-shaped notch 311, the friction force between the guide disc 31 and the main shaft 22 is not smaller than the force of the first rod 321 acting on the guide disc 31, the guide disc 31 rotates reversely along with the main shaft 22, and then the lock 33 continues to rise to the unlocking position 206 of the side container corner fitting side hole 205, at the moment, the sliding block 323 also moves to the other side of the arc-shaped notch 311, and the first rod 321 is rotated from the diameter direction of the guide disc 31 to the tangential direction of the guide disc 31 by the effect of the guide disc 31, so that the second rod 322 is mostly retracted into the casing 10 to complete unlocking. Wherein the arcuate slot 311 serves to reduce wear caused by relative movement between the guide disk 31 and the spindle 22.

Further preferably, the longitudinal coupling device 20 further comprises a connection plate 21, the connection plate 21 being rotatably mounted on top of the spindle 22 and being located outside the housing 10. The top of the shell 11 of the housing 10 is provided with a clamping groove 12 which is matched with a connecting plate 21, and the connecting plate 21 can rotate to be positioned in the clamping groove 12, so that the connection between the longitudinal connecting device 20 and the housing 10 is realized. The rotation among the connecting plate 21, the shell 10 and the main shaft 22 is independent. The housing 10 is detachable along a central plane.

Further preferably, the longitudinal coupling device 20 further comprises an eccentric shaft 23 and a spring 231; the eccentric shaft 23 is located between the main shaft 22 and the engaging member 24, the main shaft 22 and the engaging member 24 are collinear with each other, and the axis of the eccentric shaft 23 is parallel to the axes of the main shaft 22 and the engaging member 24. The spring 231 is sleeved on the eccentric shaft 23 and is used for helping the eccentric shaft 23 to return to the normal position after being partially bent, and specifically, two limiting pieces 232 which are arranged at intervals up and down are arranged on the eccentric shaft 23, and the spring 231 is positioned between the two limiting pieces 232. The eccentric shaft 23 is an eccentric part in the main shaft 22, and plays a role in enhancing the container dumping prevention. As shown in fig. 12-13, the working principle is as follows:

when the container is to be dumped, one side of the bottom is a dumping fulcrum, the other three sides of the container have a disengaging trend, at the moment, the part with the disengaging trend is provided with two full-automatic container interlocking mechanisms 100, if the dumping force applied by the two mechanisms has a component force perpendicular to the plane direction of the main rotation shaft of the main shaft 22 and the eccentric shaft 23, the eccentric shaft 23 rotates to the side far away from the dumping fulcrum, and the size of the container is considered to be unchanged, so that the dumping trend of the container is weakened due to the increase of the distance between the eccentric shaft 23 and the dumping fulcrum according to the Pythagorean theorem, namely the inclination angle alpha is reduced.

In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.
