[0037] Embodiment one: a method for transporting foundation beams into a ship's cold storage.
[0038] For a ship 1 with multiple cold storage layers 5 inside, and in the manufacturing stage, only the hull part is available, the power system is not pulled, the transport elevator is not installed, and only manpower can be used to transport the foundation beams 6 through the stairs. The work is especially suitable for the ship structure where the elevator shaft 4 is located on one side of the cold storage layer 5, so this embodiment provides a method for transporting foundation beams into a ship's cold storage, including the following steps:
[0039] Step one: the elevator shaft 4 is arranged adjacent to the cold storage layer 5, and the cold storage layer 5 is located on the left side of the elevator shaft 4. The gantry lifting assembly 2 and the cantilever lifting assembly 3 are installed on both sides of the top of the elevator shaft 4 of the ship, specifically the gantry lifting assembly 2 is located on the left side of the opening at the top of the elevator shaft 4, and the cantilever lifting assembly 3 is located on the right side, as shown in Figure 1 ;
[0040] Step two: the top of the cold storage layer 5 can be regarded as a transport deck, and the foundation beam 6 is transported along the top of the cold storage layer 5 to the elevator shaft 4 direction by the transport vehicle, until the foundation beam 6 is transported between the gantry lifting assembly 2 and the cantilever lifting assembly 3, and the hooks on the gantry lifting assembly 2 and the cantilever lifting assembly 3 are respectively hooked on both ends of the foundation beam 6, as shown in Figure 2 ;
[0041] Step three: when the hooks of the gantry lifting assembly 2 and the cantilever lifting assembly 3 are respectively hooked on both ends of the foundation beam 6, the foundation beam 6 is in a horizontal lifting state at this time, that is, in this state, it is necessary to ensure that the height of the gantry lifting assembly 2 and the cantilever lifting assembly 3 lifting the foundation beam 6 is consistent, so that the foundation beam 6 is controlled by the gantry lifting assembly 2 and the cantilever lifting assembly 3. When it is lifted horizontally and synchronously upward, it is not easy to deviate, and the lifting efficiency is higher, as shown in Figure 3 ;
[0042] Step four: since the base beam 6 is horizontally lifted to a certain height, and considering the length of the base beam 6, there is a case that the length of the base beam 6 exceeds the width of the elevator shaft 4, if the base beam 6 is horizontally lifted into the elevator shaft 4, it is easy to be stuck, and it is not easy to operate, because the lifting direction of the base beam 6 needs to be adjusted, therefore, when the lifting height of the base beam 6 is equal to the length of the base beam 6, there is enough distance between the base beam 6 and the top of the freezer layer 5, even if the base beam 6 quickly turns, there will be no collision, but for safety, the hook of the gantry lifting assembly 2 slowly moves downward, and the cantilever lifting assembly 3 remains stationary, here, for the sake of convenience, the two ends of the base beam 6 are defined as the first end and the second end, the gantry lifting assembly 2 hooks the first end of the base beam 6, and the cantilever lifting assembly 3 hooks the second end of the base beam 6, when the hook of the gantry lifting assembly 2 moves downward, it is equivalent to the first end of the originally horizontally placed base beam 6 moving downward, while the second end is stationary, that is, at this time, the base beam 6 turns downward around the second end as the fulcrum, and then controls the base beam 6 to turn up and down, as shown in Figure 4 ;
[0043] Step five: when the base beam 6 turns vertically downward, that is, the first end vertically downward, the gantry lifting assembly 2 is unhooked, and the cantilever lifting assembly 3 alone hangs the base beam 6, by vertically lifting the base beam 6 through the cantilever lifting assembly 3, it can ensure that the base beam 6 has sufficient adjustment space in the elevator shaft 4, and due to the weight of the base beam 6 itself, the stability of single-point lifting is also high, as shown in Figure 5 ;
[0044] Step six: control the base beam 6 to move vertically downward along the elevator shaft 4 through the cantilever lifting assembly 3, when the downward first end of the base beam 6 moves to be flush with the bottom of the freezer layer 5 where the base beam 6 needs to be installed, the base beam 6 stops moving downward, as shown in Figure 6 ;
[0045] Step seven: adjust the turning of the base beam 6, so that the base beam 6 turns to be horizontal with the bottom of the freezer layer 5, and then transport the base beam 6 to the freezer layer 5 for installation, as shown in Figure 7 .
[0046] Based on the above scheme, the movement of the foundation beam 6 is realized by cooperation of the gantry lifting assembly 2 and the cantilever lifting assembly 3, the elevator shaft 4 located at the edge of the cold storage layer 5 is fully utilized as a transportation channel, the gantry lifting assembly 2 and the cantilever lifting assembly 3 cooperate to control the horizontal transportation, turning and vertical transportation of the foundation beam 6, without additional labor cost, the transportation and installation of the foundation beam 6 are realized in a fully mechanized and automated manner, the foundation beam 6 is quickly loaded into the cabin, the construction period of the ship cold storage is shortened, the labor cost is greatly saved, and the stability and reliability in the transportation process of the foundation beam 6 are guaranteed by the mechanized transportation, and the precision control is realized.
[0047] In some embodiments, a buffer pad layer is laid on the inner wall of the elevator shaft 4 away from the cold storage layer 5, that is, the buffer pad layer is laid on the right side in the elevator shaft 4. Since the left side in the elevator shaft 4 is in communication with the cold storage layer 5, it is equivalent to an open design. In order to effectively protect the foundation beam 6 and the elevator shaft 4, the buffer pad layer needs to be laid on the right side inside the elevator shaft 4 where the foundation beam 6 may collide, so that even if the foundation beam 6 collides, the damage can be reduced under the buffering effect, and damage can be avoided. A buffer layer can also be appropriately laid on the left side opening of the elevator shaft 4 to prevent the foundation beam 6 from shaking too much and colliding with the edge of the opening.
[0048] Preferably, an adjusting assembly can be installed on the side of the cantilever lifting assembly 3 facing the gantry lifting assembly 2, the adjusting assembly abuts against the foundation beam 6 to adjust the turning of the foundation beam 6, so that the foundation beam 6 completes collision-free turning. The adjusting assembly can be a telescopic rod, the telescopic rod extends from the cantilever lifting assembly 3 towards the gantry lifting assembly 2, when the cantilever lifting assembly 3 and the gantry lifting assembly 2 cooperate to adjust the direction of the foundation beam 6, one end of the telescopic rod extends towards the gantry lifting assembly 2 and abuts against the foundation beam 6, avoiding the foundation beam 6 turning too much at once, and ensuring that the foundation beam 6 completes the turning action slowly and safely.
[0049] Specifically, one end of the telescopic rod is provided with a clamping part matched with the foundation beam 6, the clamping part can effectively clamp the foundation beam 6, when the foundation beam 6 turns downward, the telescopic rod synchronously shrinks to cooperate with the turning of the foundation beam 6, improving the stability of the turning of the foundation beam 6 without affecting the turning of the foundation beam 6.
[0050] Meanwhile, the conveying device is placed on the inner bottom surface of the cold storage layer 5, the hook on the conveying device hooks the downward end of the foundation beam 6, the cantilever crane lifting assembly 3 is synchronized with the conveying device to move the foundation beam 6 in the direction away from the cold storage layer 5 until the foundation beam 6 is spaced one meter from the inner wall of the elevator shaft 4, then the movement is stopped, the conveying device drives the foundation beam 6 to move horizontally in the direction of the cold storage layer 5, the cantilever crane lifting assembly 3 lowers the foundation beam 6, until the foundation beam 6 is placed horizontally, when the foundation beam 6 is completely placed in the cold storage layer 5, the cantilever crane lifting assembly 3 is unhooked. The conveying device can be a conveying vehicle on which a telescopic hook is installed, the telescopic hook is extended towards the foundation beam 6 and hooks the first end of the foundation beam 6, the telescopic hook first cooperates with the cantilever crane lifting assembly 3 to move the foundation beam 6 vertically to the right, when the foundation beam 6 is still one meter away from the right inner wall, at this time, the foundation beam 6 is controlled to turn without collision, the foundation beam 6 can be safely controlled to turn, the specific adjustment of the turning is to control the telescopic hook to shrink in the direction of the cold storage layer 5, and at the same time, the cantilever crane lifting assembly 3 lowers the foundation beam 6, so that the foundation beam 6 can slowly turn in a gradually inclined state, when the foundation beam 6 is turned to be placed horizontally, it indicates that the turning is completed, at this time, the foundation beam 6 needs to be moved horizontally to the conveying vehicle, when the foundation beam 6 is stably placed on the conveying vehicle, the cantilever crane lifting assembly 3 is unhooked.
[0051] As an optional embodiment, the guide rail is placed obliquely between the cold storage layer 5 and the elevator shaft 4, when the foundation beam 6 abuts against the guide rail, the speed of the foundation beam 6 is reduced to make the foundation beam 6 slide into the cold storage layer 5 along the guide rail. The surface of the guide rail needs to be paved with a buffer layer, because the guide rail is obliquely arranged, when the foundation beam 6 abuts against the guide rail, the contact area between them is small and easy to be damaged, so the buffer layer can effectively solve the problem of small contact area, and when the foundation beam 6 abuts against the guide rail, the foundation beam 6 will gradually incline along the direction of the guide rail, at this time, the foundation beam 6 is slowly lowered, and only when most of the foundation beam 6 enters the cold storage layer 5, the lowering is stopped, it needs to be noted that the cantilever crane lifting assembly 3 needs to move the hook position to the left according to the position of the foundation beam 6 while lowering the foundation beam 6, so that the rope connected with the hook is always aligned with the second end of the foundation beam 6, so as not to interfere with the movement of the foundation beam 6.
[0052] Further, a sliding device is arranged between the guide rail and the inner wall of the elevator shaft 4, and the guide rail can be moved up and down through the sliding device, so that the guide rail can be arranged at any angle between any cold storage layer 5 and the elevator shaft 4. A telescopic device is arranged at the bottom of the end of the guide rail in contact with the cold storage layer 5, and the telescopic device drives the guide rail to move up and down at the same angle through cooperation with the sliding device. In this scheme, the sliding device is arranged on the right side wall of the elevator shaft 4, and the telescopic device is arranged at the bottom of the left side wall of the elevator shaft 4. One end of the telescopic device is in contact with the left end of the guide rail, and the sliding device is connected with the right end of the guide rail. Through the connection and cooperation of the telescopic device and the sliding device, the guide rail can be installed at the door of different cold storage layers 5 in the elevator shaft 4 at the same angle. The whole moving process does not need manual operation, and can be directly realized by controlling the actions of each device through the system, improving the intelligent automation of the manufacturing process, and further improving the assembly and manufacturing efficiency.
[0053] Optionally, a position sensor is arranged on the cold storage layer 5 to detect the position of the base beam 6. When the base beam 6 moves to the specified position, the position sensor sends a stop descending instruction to the cantilever frame lifting assembly 3, and the cantilever frame lifting assembly 3 stops the descending action.
[0054] Optionally, an angle sensor for detecting the inclination angle of the base beam 6 is arranged on the cantilever frame lifting assembly 3. When the angle of the base beam 6 is detected to be perpendicular to the horizontal line, a hooking-off instruction is sent to the gantry frame lifting assembly 2, and the gantry frame lifting assembly 2 is unhooked.

[0056] A base beam access device in a ship cold storage, comprising a gantry frame lifting assembly 2 and a cantilever frame lifting assembly 3, the gantry frame lifting assembly 2 and the cantilever frame lifting assembly 3 are arranged on the top of the two sides of the elevator shaft 4 respectively. The following method steps are used when the access device is used:

[0059] S3, when the lifting height of the base beam 6 is equal to the length of the base beam 6, control the hooks of the gantry frame lifting assembly 2 to move downward, and then control the base beam 6 to turn up and down;
