Description

Lashing rod

Technical field

The invention relates to the Lashing rod that uses when bundling the freight container that piles up.

Background technology

Usually, transporting at boats and ships under the situation of a plurality of freight containers, is that these freight containers are stacked as multilayer, and the freight container of each layer is bundled, and reaches the purpose of fixed set vanning.

When being bundled, uses by freight container Lashing rod.Lashing rod has the hook part of the circumference of the mating holes that forms on the bight metal piece that can be engaged in freight container.When using this Lashing rod that freight container is bundled, hook part inserts the mating holes of bight metal piece and cooperates hook part at the circumference of this mating holes, then, the end that turn buckle is buckled (turnbuckle) is matched with the rearward end of Lashing rod, the other end that turn buckle is buckled is matched with the complexed metal spare that is provided with on the freight container bearing surface, and that carries out that turn buckle buckles is fastening.

The above-mentioned Lashing rod that uses as the binding of freight container, on the books in the real fair 4-39838 communique of patent documentation, this Lashing rod, in the coupling link of the front end setting of bar, be inserted in the connection board that is provided with on the hook part, and prevent to come off, can hook part be connected on the bar with freely swinging.

In above-mentioned Lashing rod, because hook part can freely swing, so be matched with the mating holes of bight metal piece at this hook part, the rotation of being buckled by turn buckle is given tensile force to bar and when bundling, bar just can be given tensile force at the length direction of bar towards draw direction.Therefore, have the institutes such as distortion breakage that bar can not take place and do not wish the phenomenon that takes place, the feature that freight container can be bundled very securely.

Yet, because the number of plies that the freight container that piles up on the deck of hull piles up increases, so as Figure 6 and Figure 7, the compartment of terrain is provided with the binding bridge (lashing bridge) 21 that prolongs along the side of a ship side direction of hull on the length direction at hull on the deck 20, the freight container B of stacked multilayer between this binding bridge 21.

In this case, during container fixing, as shown in the drawing, by buckle the 31 bight metal piece C-1 horizontal binding methods of level binding almost that will descend the top of the bight metal piece C-2 of bottom of freight container B-2 of several second layers or undermost freight container B-1 by Lashing rod 30 and turn buckle, owing to can prevent the B-1 of this level binding, the distortion of B-2 effectively, so can access highly stable stacked state.

Yet, among bight metal piece C-1, the C-2 on being arranged at freight container B, as shown in Figure 7, because the mating holes H that on the metal piece C-1 of the bight on top, forms ₁Width dimensions W ₁Than the mating holes H that on the metal piece C-2 of the bight of bottom, forms ₂Width dimensions W ₂Want big, so the hook part of the Lashing rod of putting down in writing is matched with the mating holes H of upper corner metal piece C-1 in described communique ₁And carrying out level when binding, hook part is for mating holes H ₁Use level little, if give the rotational force of the direction that comes off to hook part, the danger that breaks away from from mating holes is just arranged in when binding, by the mono-Lashing rod just can not with mating holes H ₁, H ₂Different two kinds bight metal piece C-1, the C-2 of width dimensions corresponding.

Here, between binding bridge 21, there be its length dimension multiple freight container different among the cargo-carring freight container B with height dimension, when these freight containers B is loaded between the binding bridge 21, shown in Fig. 8 (I), (II), distance L 1, L2 difference to binding bridge 21, under the short situation of the distance between freight container B shown in Fig. 8 (I) and the binding bridge 21, need: the side of the guide pillar (guide post) 22 that above binding bridge 21, is provided with make hook part down, reduce Lashing rod 30, hook part is inserted the mating holes H of bight metal piece C-1, C-2 ₁, H ₂And fall operation by the volt of Lashing rod 30 and make hook part be matched with mating holes H ₁, H ₂Circumference.

On the other hand, shown in Fig. 8 (II), under the situation of the distance between freight container B and the binding bridge 21, need: control Lashing rod 30, keep Lashing rod 30 to be almost level, make the mating holes H of hook part insertion bight metal piece C-1, the C-2 of Lashing rod 30 front ends ₁, H ₂, and be that the center makes its rotation with the axle center of Lashing rod 30, the hook part of front end is matched with mating holes H ₁, H ₂Circumference.

Yet, because the employed Lashing rod of binding of freight container B has the above weight of 7kg, so hook part is for the mating holes H of bight metal piece C-1, C-2 ₁, H ₂The position align and have very big difficulty.

Particularly, shown in Fig. 8 (II), under the situation of the distance between freight container B and the binding bridge 21, hook part can freely swing, in the front end and the swing of the contacted situation lower draw-bar of freight container parts of this hook part, attitude change is because the variation of this posture makes hook part can not insert mating holes, so be necessary to make the posture of hook part to get back to suitable posture and the compounding practice of reforming, existing takes time and energy for the cooperation of hook part etc. does not wish the phenomenon that takes place very much.

Summary of the invention
