Description

Technical Field

[0001] The invention relates to the technical field of lashing pieces and preparation thereof, and in particular to a light-weight and high-strength lashing piece for ships and a preparation device thereof. Background Art

[0002] Taking into account the frequent shaking of ships during navigation, a large number of lashing parts are used to fix the materials on the ship relative to the ship. For example, the lashing parts of ship containers are one of the commonly used lashing parts.

[0003] After searching, the invention patent with Chinese patent application number CN202320208922.6 discloses a lashing device for ship containers, which is roughly described as including a different direction screw and a screw sleeve. A rotating seat is provided at the center of the side of the different direction screw. The side of the different direction screw is located at the two ends of the rotating seat and is respectively provided with a thread one and a thread two adapted to the screw sleeve. The thread directions of the thread one and the thread two are opposite. There are two screw sleeves and a plurality of hook-type lock buckles are provided on the sides. The side of the rotating seat is provided with a plurality of rotating rods, and also includes a rotating sleeve adapted to the rotating rod. When in use, the connecting pieces at both ends are respectively connected to the hook-type lock buckles on the two screw sleeves on the different direction screw. Before connection, a suitable number of hook-type lock buckles can be selected according to the connection method of the connecting piece. After the connection is completed, the rotating rod is manually rotated to pre-tighten the screw sleeves at both ends. When the manual method cannot be continued, the rotating sleeve is used to rotate, and then the screw sleeve is further tightened, so that the connection between it and the connecting piece can achieve the effect of tightening and straightening.

[0004] Although the above-mentioned prior art solution can be used for lashing of ship containers, the structural component that mainly transmits force after lashing is a single axle screw, and the corresponding connection and driving functionality of the screw are mainly realized by the threads thereon. Taking into account the overall quality and specifications of the container, if the overall quality of the container and the goods therein is large, it is easy to cause the threads on the screw to exceed the bearing capacity and cause thread failure, which will not only reduce the lashing effect, but also cause the failure of lashing disassembly, and the reliability of use needs to be further improved.

[0030] The torque motor 26 in this embodiment is a conventional device purchased on the market and known to those skilled in the art. In the present invention, we only use it and do not improve its structure and function. For those skilled in the art, its setting method, installation method and electrical connection method only need to be debugged and operated according to the requirements of its instruction manual, and will not be described in detail here.

[0031] In summary, the working principle of the light-weight and high-strength lashing member for ships is that, when in use, the light-weight and high-strength lashing member for ships is first installed relative to the corner column of the container, and after the installation is completed, the vertical frame 2 is fixedly connected to the corner column of the container, as shown in the attached figure. Figure 6As shown, part of the vertical frame 2 leaks out from the bottom end of the container corner column, and under the support of the elastic spring 11, the threaded barrel 8 will be pushed upward relative to the screw sleeve 1. Due to the threaded transmission of the threaded barrel 8 and the screw sleeve 1, the limit hook plate 7 on the threaded barrel 8 will be rotated relative to the vertical frame 2 and collected into the corresponding side opening 6, and this state is maintained. When the containers are stacked up and down, the container corner columns of the containers stacked up and down form a corresponding upper and lower position, which will also form a corresponding upper and lower position of the ship's lightweight and high-strength lashing parts. When the upper layer of the ship's lightweight and high-strength lashing parts forms a relative action with the lower layer of the ship's lightweight and high-strength lashing parts, the support end cover 9 presses the contact pressing block 15, thereby causing the vertical center rod 3 to move downward relative to the vertical center frame in the vertical center hole 4. The downward movement of the vertical center rod 3 will also push the threaded barrel 8 to move downward relative to the screw sleeve 1. This causes the screw sleeve 1 to rotate in the middle expansion 5, and then the limit hook plate 7 is rotated out in the side opening 6. The rotated limit hook plate 7 will form a hook limit relative to the hole on the container corner column, so that the mutual binding between the containers stacked on top of each other can be achieved. For the top layer of the container, it is necessary to use the top pressure structure to achieve the binding limit between it and the container on the second top layer. When the top pressure structure is used, it is relatively inserted relative to the container corner column, and then the threaded rod 14 is rotated through the opening on the top end of the container corner column, so as to increase the relative support height of the top support frame 12 and the bottom support frame 13, and finally cause the top support frame 12 to be relatively tightened relative to the container corner column, and through the bottom support frame 13 relative to the contact pressing block 15 to form a relative push, finally realize the corresponding limit hook plate 7 relative to The side opening 6 is rotated out, and the relative position of the limit hook plate 7 after being rotated out relative to the side opening 6 is stabilized.

[0032] Furthermore, when the supporting preparation device for lightweight and high-strength marine lashing parts is in use, the relative position adjustment of the two opposing clamping frames 19 can be achieved by rotating the bidirectional screw 21, and finally the clamping positioning of the fixing frame 16 relative to the vertical frame 2 is achieved. After the positioning is completed, the operator holds the horizontal handle 35 in one hand and the longitudinal handle 36 in the other hand, and the cutting operation of the vertical middle hole 4, the middle flare 5 and the side opening 6 on the vertical frame 2 can be achieved by synchronously and relatively coordinating the horizontal handle 35 and the longitudinal handle 36. In this case, the horizontal handle 35 is kept fixed, and the single By applying force to the longitudinal hand handle 36, the cutting tool 27 can be given a longitudinal feed, and by applying force to the horizontal hand handle 35, the position of the cross frame 25 relative to the rotating member 24 can be driven, so that the cutting tool 27 can be given a lateral feed relative to the vertical frame 2. At the same time, if the rotating member 24 is rotated relative to the portal frame 23 by controlling the horizontal hand handle 35, the application of lateral feed in different directions can be achieved. The output shaft of the torque motor 26 is equipped with a clamping chuck that matches the cutting tool 27 to facilitate the selection and matching clamping of different cutting tools 27.
