[0048] This embodiment provides a ship, which includes a hull, a derrick and an elevator. The derrick is arranged on the hull, and the elevator is installed on the derrick. The derrick provides the necessary lifting capacity and pipeline connection capacity for the ship to meet the maximum operating water depth and maximum drilling depth through the elevator. The elevator includes elevator guide rails, and the function of the elevator guide rails is to guide and support the elevator car to move along a certain track in the hoistway. Among them, the ship can specifically be a drilling ship.
[0049] When the elevator is installed, since the upper part of the elevator guide rail is about 5 meters higher than the upper surface of the derrick and is usually about 40 meters high from the drill floor, there will be unsafe factors such as swaying at the upper part of the guide rail when the elevator runs up and down on the drilling ship in the wind and waves. To prevent the swaying and unsafe factors at the upper part of the guide rail when the elevator runs up and down, there are usually two solutions in the prior art: First, by changing the upper structure of the derrick to make the height of the derrick consistent with the height of the elevator guide rail; Second, replace the elevator guide rail with a stronger stress-bearing material.
[0050] In the prior art, for the first solution, the structure of the derrick is changed, and the derrick needs to be customized again, with a long manufacturing cycle and high cost; for the second solution, it will change the conventional design and material selection of the elevator guide rail, and requires re-design and calculation, increasing the cost.
[0051] To solve the above problems, as Figures 1-4As shown in the figure, this embodiment provides an elevator guide rail support device 100, which includes a support member 10, a first connection mechanism 20, and a second connection mechanism 30. The support member 10 extends along the length direction of the elevator guide rail 300. The first connection mechanism 20 is arranged on the support member 10 and is detachably connected to the hoistway 200. The second connection mechanism 30 is arranged on the side of the support member 10 away from the first connection mechanism 20 and is detachably connected to the elevator guide rail 300. By connecting the elevator guide rail 300 to the hoistway 200 through the elevator guide rail support device 100, it can not only meet the requirement of the support force for the elevator guide rail 300, but also does not need to change the structure of the hoistway 200 and the product design of the elevator guide rail 300. The structure is simple and the production cost is reduced. The first connection mechanism 20 and the second connection mechanism 30 are respectively detachably connected to the hoistway 200 and the elevator guide rail 300, which is convenient for the installation of the elevator guide rail support device 100.
[0052] Specifically, the support member 10 is a cylinder. The support member 10 is the main load-bearing member, and at the same time provides the force and fixed position on the hoistway 200 side and the elevator guide rail 300 side. Therefore, the support member 10 is made of ferroalloy material and has high strength.
[0053] As Figure 1 and Figure 2 As shown in the figure, the number of the first connection mechanisms 20 is two, and the two first connection mechanisms 20 are arranged at intervals along the length direction of the support member 10, so that the force between the support member 10 and the hoistway 200 is uniform, and at the same time, the force of the elevator guide rail support device 100 is transmitted to the hoistway 200. In other embodiments, the number of the first connection mechanisms 20 can also be three, four or more, which is not limited herein.
[0054] The number of the second connection mechanisms 30 is four, and the four second connection mechanisms 30 are arranged at intervals along the length direction of the support member 10, so that the force between the support member 10 and the elevator guide rail 300 is uniform, and at the same time, the force during elevator operation is transmitted to the support member 10. In other embodiments, the number of the second connection mechanisms 30 can also be two, three or more, which is not limited herein.
[0055] Specifically, the first connection structure includes at least two first connecting members 21 and a first connection end plate 22. At least two first connecting members 21 are arranged at intervals on the circumferential side of the support member 10. The first connection end plate 22 is arranged on the side of the first connecting member 21 away from the support member 10 and is connected to the ends of all the first connecting members 21. As Figure 3 and Figure 4As shown, the first connection end plate 22 and the two first connectors 21 located at the edge together roughly enclose a triangle, thereby improving the support strength of the first connection mechanism 20; the first connector 21 located at the middle position is roughly at the position of the median line of the triangle, further improving the support strength of the first connection mechanism 20.
[0056] Optionally, the first connector 21 is welded to the support member 10. Optionally, the first connection end plate 22 is welded to the first connector 21. This is convenient for improving the connection stability between the first connector 21 and the support member 10 and between the first connection end plate 22 and the first connector 21.
[0057] Optionally, the elevator guide rail support device 100 further includes a first fixing component 40. The first connection mechanism 20 and the derrick 200 are detachably connected through the first fixing component 40, which is convenient for the quick disassembly and assembly of the first connection mechanism 20 and the derrick 200, and thus improves the installation efficiency of the first connection mechanism 20 and the derrick 200. Specifically, the first fixing component 40 includes a bolt and a nut. After the bolt passes through the derrick 200 and the first connection end plate 22, the bolt is threadedly connected to the nut, and the bolt and the nut cooperate to fix the derrick 200 and the first connection end plate 22. Through this setting, it is convenient for the quick disassembly and assembly of the derrick 200 and the first connection end plate 22, and improves the installation efficiency of the elevator guide rail support device 100.
[0058] As Figure 3 and Figure 4 shown, the number of the first fixing components 40 is multiple, and the multiple first fixing components 40 are arranged in an array, which is beneficial to improving the connection stability between the derrick 200 and the elevator guide rail support device 100.
[0059] Optionally, the second connection mechanism 30 includes a second connector 31 and a second connection end plate 33. The second connector 31 is arranged on the support member 10; the second connection end plate 33 is arranged at one end of the second connector 31 away from the support member 10. The second end plate is used to connect the elevator guide rail 300. Among them, as Figure 4 shown, the number of the second connectors 31 is three, and the three second connectors 31 surround the circumference of the support member 10 and roughly form a triangle, which is convenient for improving the support strength of the second connector 31.
[0060] Optionally, the second connector 31 is welded to the support member 10. This is convenient for improving the connection stability between the second connector 31 and the support member 10.
[0061] Furthermore, the second connecting mechanism 30 further includes an extension member 32. One end of the extension member 32 is connected to the second connecting member 31, and the other end is connected to the second connecting end plate 33. On the one hand, the extension member 32 can improve the strength of the second connecting mechanism 30. On the other hand, it is used to compensate for the distance between the elevator guide rail support device 100 and the elevator guide rail 300, so that the second connecting end plate 33 can be closely attached to the elevator guide rail 300.
[0062] Optionally, the elevator guide rail support device 100 further includes a second fixing component. The second connecting mechanism 30 and the elevator guide rail 300 are detachably connected through the second fixing component, which facilitates the quick disassembly and assembly of the second connecting mechanism 30 and the elevator guide rail 300, and thus improves the installation efficiency of the second connecting mechanism 30 and the elevator guide rail 300. Specifically, the second fixing component can be a combination of a screw and a nut. The screw passes through the elevator guide rail 300 and the second connecting end plate 33 and is threadedly connected to the nut. In other embodiments, the second fixing component can also be a rivet or a pin, etc.
