[0030] The fixed support device for ship provided in the embodiment of the present application is connected to the main support member and the bottom plate respectively through the auxiliary parts to form a whole. The bottom plate can be used by laying it flat on the ground. When in use, the device is moved to under the stern by hoisting the lifting lugs set on the main support member with a crane. After the hull is formed or before launching, the device can be moved out from under the stern by a crane without the need for installation and dismantling. Compared with the stacked steel pier support in the prior art, the device is safer.

[0031] In some optional embodiments, the fixed support device for ship further comprises a support plate, and the support plate is horizontally arranged on the top of the main support member. The support plate is arranged on the top of the main support member, and the stern is supported by the support plate, so that the contact area with the stern is increased, so that the support effect is more stable, and the reliability and stability of the device are improved.

[0032] In some optional embodiments, the marine fixed support device further comprises reinforcing ribs, which are respectively connected to the support plate and the main support member. The reinforcing ribs are connected to the bottom surface of the support plate and the side wall of the main support member to strengthen the support plate, improve the strength of the support plate, and improve the stability and service life of the device.

[0033] In some optional embodiments, at least two of the auxiliary parts are evenly distributed around the main support part. For example, there are four auxiliary parts, and the four auxiliary parts are evenly distributed around the main support part, so that the force is evenly distributed and the center of gravity is along the main support part. When used to support the stern, it is relatively stable. Each auxiliary part forms a triangular structure with the main support part and the bottom plate, which has good stability.

[0034] In some other optional embodiments, two, three or more auxiliary parts may be provided; specifically, when two auxiliary parts are provided, the two auxiliary parts are symmetrically arranged on both sides of the main support member; or, when three auxiliary parts are provided, the three auxiliary parts are symmetrically arranged on both sides of the main support member.

[0035] In some optional embodiments, the ship-mounted fixed support device further comprises at least two plug-in brackets, the plug-in brackets are respectively connected to the auxiliary component and the main support component, and each of the plug-in brackets is connected to one of the auxiliary components. The plug-in brackets are located between the auxiliary component and the main support component and are arranged horizontally. The plug-in brackets are convenient for forklift transportation. The forklift is inserted under the plug-in brackets, which can facilitate the horizontal movement of the ship-mounted fixed support device and facilitate the removal of the ship-mounted fixed support device from the stern. The plug-in brackets can use channel steel and be connected to the auxiliary component and the main support component by welding.

[0036] In some optional embodiments, by setting the height of the end where the auxiliary part is connected to the main support part, and the height of the plug-in bracket, the overall center of gravity of the marine fixed support device is lower than the plug-in bracket. By setting the height of the main support part to L, and the height of the end where the auxiliary part is connected to the main support part to L / 3, the overall center of gravity of the device is located in the lower half of the main support part, thereby improving stability. By setting the height of the plug-in bracket to be greater than L / 6, the overall center of gravity of the device is lower than the plug-in bracket, and when the device is transported by a forklift, it can be more stable, thereby improving the stability and safety of the device.

[0037] In some optional embodiments, a counterweight is provided under the bottom plate, so that the overall center of gravity of the marine fixed support device is lower than the plug-in bracket. By providing the counterweight under the bottom plate, the overall center of gravity of the marine fixed support device is lower than the plug-in bracket, and when the device is transported by a forklift, it can be more stable, thereby improving the stability and safety of the device.

[0038] In some optional embodiments, the counterweight is cast by cement mortar, and the bottom plate is pre-embedded in the cement mortar. The counterweight is cast by cement mortar, and during the casting process, the bottom plate is pre-embedded in the cement mortar. After the casting is completed, the counterweight and the bottom plate are integrated.

[0039] In some optional embodiments, the marine fixed support device further comprises a ladder, which is arranged on the outer wall of the main support member. By arranging the ladder on the outer wall of the main support member, it is convenient for operators to climb up, and it can be used as a ladder when performing maintenance and installation at high places, so that one object can be used for multiple purposes, thereby improving the scope of application of the device. The ladder can be composed of a plurality of square steel steps, which are welded to the main support member.

[0040] In some optional embodiments, the ladder is arranged in a vertical direction and avoids the auxiliary components. The ladder is arranged in a vertical direction and is arranged between two adjacent auxiliary components to avoid the auxiliary components and improve the reliability of the device.

[0041] In some other optional embodiments, the ladder is arranged to spirally rise around the main support member. Near the position where the auxiliary member is connected to the main support member, a section of the ladder is arranged in the vertical direction, and the section of the ladder is arranged between two adjacent auxiliary members to avoid the auxiliary members. The spiral rise of the ladder can prevent the ladder from affecting the center of gravity of the device, so that the center of gravity of the device is maintained on the center line of the main support member, so that the device can be more stable when supporting the stern, thereby improving the reliability and stability of the device.
