Tie rod module of container knotter and manufacturing method thereof

The present invention relates to a container fastening device, and more particularly to a tie rod module of a container tie and a method of manufacturing the same.

Containers generally loaded on freighters are stacked in multiple layers. In order to prevent the container wheels from swaying during driving and causing the container to be unstable, most container tiers will be used to tie the containers to decks or bridges, such as TW Patent No. Patent cases such as I250956, M284618, and I245730.

As shown in FIG. 1 and FIG. 2, most of the decks or bridges of the general cargo ship are provided with a plurality of fixing bases 503 for mounting on the most of the Eye Plates. Each of the binding plates 5 has a circular hole 501 and a wearer. A shaft pin 502 provided in the circular hole 501. A conventional container tier includes a tightener 6 pivotally coupled to the axle pin 502 of the lashing plate 5 and a tie bar 7 (Lasing Rod) adjustably coupled to the tightener 6. The pull tie bar can be used to generate a hook setting position with respect to a container corner 401 (Corner Casting Of Container) of a container 4, and the pull tie bar module 8 includes a head support 1 (Support Of Rod Head), a Rod Head 2 and a Pin 3 (Pin). The head support 1 has a perforation The puller head 2 has a hook body 201 located outside the head support base 1 , a connecting body 202 coupled to the hook body 201 and threaded through the through hole 102 , and a hook body 201 disposed on the hook body 201 . The connecting member 202 has a tip hole 204 through which the tip rod 3 can pass.

In use, the knotter 6 of the knotter is pivotally connected to the axle pin 502 of the lashing plate 5, and the knotter can be positioned on the deck or bridge of the freighter, and the tie rod is utilized at the other end. The pulling rod head 2 of the module 8 and the head supporting base 1 can pivot relative to each other, so that the hook body 201 can be buckled in a button hole 402 preset by the container angle 401 of the container 4, that is, The container 4 can be stabilized.

The overall structure of the tie rod module 8 of the above-mentioned container binder using the head support 1, the tie rod 2, and the tip rod 3 can achieve the intended use purpose, but in order to take into account the structural strength and assembly The tip rod 3, the tie rod head 2 is provided with a considerable flesh around the tip hole 204, and the tip rod 3 must also have a considerable circular diameter, as shown in Fig. 2, in the tie rod head 2 When the size of the head support 1 is fixed, a movable distance d between the head support 1 and the container angle 401 is small, and the deck space of the freight wheel is limited, so that the tie is tight. The angle of time is limited (see Figure 1), and when the container tie is X-shaped, the stacked container tiers will interfere with each other. Due to the shaking of the hull carrying process, the tie rod 7 will be phased. Interference creates constant friction, and a severe groove 103 (see Figure 2) after friction will even produce a bending deformation (see Figure 2). Afterwards, the tie rod will be removed from the groove and deformation. Breaking will affect the service life and safety of the container tie.

That is, the container tier receives the rod 3 as a member for positioning the head support 1 relative to the tie rod 2, so the head support 1 receives the tip 3 The other tie bars 7 that overlap with the other crosses interfere with each other.

Under the angle of the container tie puller that cannot be extended, the container tier When used, they will overlap each other. In order to avoid mutual interference, the tie rod 7 can only be moved outwardly from the ship system, that is, the distance A1 between the fixed seat 503 and the container in FIG. 1 is increased, but currently The shipping and hull manufacturing of the hull space will consume too much manufacturing cost and space available for the hull, and the tie rod module 8' also includes a head support 1' and a tie rod head 2' And a lock bar 3' that is locked to the head support 1', the head support 1' has a pair of pivot plates 101' and one is disposed between the pivot plates 101' and is provided for the tie bars The head 2' accommodates a channel 102' having a long slot 201' through which the lock lever 3' passes. Achieving the intended use, but the portion of the head support 1' through which the lock bar 3' passes is still required to have a considerable thickness, and the periphery of the long groove 201' is also required to have a considerable thickness in order to maintain the tie rod. The strength of the head, and because the tie rod head 2' is provided with a long groove 201', the head branch is also limited The amount of displacement of the support 1', so that in the premise of saving the hull space, there is still a container tie holder 1' which is restricted by the long groove 201' and interferes with other cross-overly stacked container tiers. technical problem.
