Description

Arrangement structure for reducing local structural stress around positioning pin of container ship Technical Field The invention belongs to the technical field of ship construction, and particularly relates to an arrangement structure for reducing local structural stress around a locating pin of a container ship. Background During the course of sailing, the container ship can encounter complex sea conditions, such as strong wind, billows, etc. The hatch cover locating pins and the transverse locking devices are usually made of high-strength materials, can bear severe offshore environments and the pressure of heavy objects, and can effectively prevent the hatch cover from moving under the extreme conditions, so that the stability and the safety of containers in the cabin are ensured. The local structure around the locating pin and the transverse locking means is deformed by resisting the movement of the hatch cover, and the locating pin is deformed more severely relative to the local structure around the transverse locking means, resulting in greater stress. Disclosure of Invention The invention aims to overcome the defects in the prior art and provide an arrangement structure for reducing the stress of the local structure around the locating pin of the container ship. In order to achieve the above object, the present invention provides the following technical solutions: The utility model provides an arrangement structure for container ship reduces local structural stress around locating pin, includes that locating pin, hatch enclose the platform, the hatch encloses the platform panel, the locating pin is located the platform panel, the hatch encloses the stringer panel, deck and supporting module, the locating pin bottom sets up on the locating pin is located the platform, locating pin upper portion side is connected with hatch encloses platform one end, the hatch encloses platform other end lower part and is connected with the hatch encloses the platform panel, the hatch encloses the platform panel lower extreme and is connected with the hatch encloses the stringer panel upper end, the hatch encloses the stringer panel lower extreme and is connected with the deck, the locating pin is located the platform lower extreme and is provided with the hatch and encloses the stringer, the hatch encloses the stringer lower extreme and is connected with the deck, the hatch encloses the stringer and corresponds the below of deck and be provided with supporting module. Further, the support module comprises a support plate, a support plate panel and relief toggle plates, wherein the support plate is connected with the lower end face of the deck, the support plate is arranged at the lower end of the support plate, the relief toggle plates are arranged on two sides of the lower end of the support plate, and the relief toggle plates comprise a first relief toggle plate, a second relief toggle plate and a third relief toggle plate. Further, the height of the supporting plate is 500-600mm, a first relieving toggle plate and a second relieving toggle plate are respectively arranged at the connection positions of the lower ends of the two sides of the supporting plate and the strong frame, and a third relieving toggle plate is arranged at the connection position of the strong frame on the right side of the supporting plate and the longitudinal ribs of the deck. Further, the supporting plate is higher than the longitudinal ribs of the deck at the lower end of the deck.
