[0031] Please refer to Figure 1 The ship equipment lifting device 10 provided in the embodiments of the present application is used for lifting ship equipment into the inside of a ship. An installation opening for the ship equipment to enter is arranged at the bottom of the ship, and the lifting device 10 is correspondingly arranged below the installation opening. The ship equipment lifting device 10 provided in the embodiments of the present application greatly reduces the risk of transferring ship equipment and improves safety.

[0032] Please refer to Figure 1In the embodiment of the present application, the lifting device 10 comprises a mounting assembly 100, a lifting assembly 200 and a lifting mechanism 300. The lifting assembly 200 is arranged above the mounting assembly 100 and is used for mounting the marine equipment. The lifting mechanism 300 is mounted on the mounting assembly 100 and the driving end of the lifting mechanism 300 is connected to the lifting assembly 200. The lifting mechanism 300 can drive the lifting assembly 200 to move towards the mounting port by rising, so as to lift the marine equipment into the mounting port.

[0033] The lifting mechanism 300 can realize rising and lowering. Since the lifting mechanism 300 is mounted on the mounting assembly 100 and the driving end of the lifting mechanism 300 is connected to the lifting assembly 200, the lifting mechanism 300 rises to drive the lifting assembly 200 to rise, and the lifting mechanism 300 lowers to drive the lifting assembly 200 to lower. Since the lifting device 10 is arranged below the mounting port, the lifting mechanism 300 rises to drive the lifting assembly 200 to move towards the mounting port, so as to lift the marine equipment into the mounting port.

[0034] Next, the lifting method of the lifting device 10 provided in the embodiment of the present application for the marine equipment is introduced.

[0035] 1) The lifting mechanism 300 drives the lifting assembly 200 to lower to the lowest point, and the marine equipment is hoisted onto the lifting assembly 200.

[0036] 2) The center of the marine equipment and the center of the mounting port are aligned by means of a plumb line, and the lifting assembly 200 is leveled by using a screw jack.

[0037] 3) The lifting mechanism 300 drives the lifting assembly 200 to rise until the marine equipment enters the mounting port, and the workers in the ship can install the marine equipment.

[0038] It should be noted that during the lifting of the marine equipment by the lifting mechanism 300, the eyebolts and the hand-operated hoists can also be used to install and hoist the marine equipment, so as to form secondary protection, further reduce the risk and improve the safety.

[0039] The lifting device 10 for the marine equipment provided in the present application can drive the lifting assembly 200 to move towards the mounting port by rising, so as to lift the marine equipment into the mounting port. Therefore, when the marine equipment is installed, the marine equipment is placed on the lifting assembly 200, and then the lifting assembly 200 is driven to move upwards by the lifting mechanism 300, so as to send the marine equipment into the mounting port. Since the marine equipment is lifted into the mounting port, it will not fall in the air, thereby greatly reducing the risk of transferring the marine equipment and improving the safety.

[0040] Please refer to Figure 1 In some embodiments, the lifting assembly 200 comprises a lifting body 210 and a fixing assembly 220, the fixing assembly 220 is mounted on the lifting body 210, the lifting body 210 is used for mounting the marine equipment, and the fixing assembly 220 can abut the circumferential side of the marine equipment to fix the marine equipment on the lifting body 210.

[0041] When the marine equipment is mounted on the lifting body 210, the fixing assembly 220 can abut the circumferential side of the marine equipment, and since the fixing assembly 220 is mounted on the lifting body 210, i.e., the fixing assembly 220 is fixedly connected to the lifting body 210, under the abutting action of the surrounding multiple fixing assemblies 220, the marine equipment can be stationary relative to the lifting body 210, thereby avoiding the marine equipment from slipping as much as possible during being lifted, and further improving the safety during the entire construction process.

[0042] Please refer to Figure 1 and Figure 2 In some embodiments, the marine equipment comprises a first equipment and a second equipment; the fixing assembly 220 comprises a plurality of first fixing members 221, the plurality of first fixing members 221 are distributed around the lifting body 210 and connected to the outer circumferential surface of the lifting body 210, and the plurality of first fixing members 221 can abut the circumferential side of the first equipment to fix the first equipment on the lifting body 210.

[0043] The marine equipment has various types, and different marine equipment has different sizes, so the abutting modes are different. For example, the marine equipment comprises a discardable ballast device, the discardable ballast device comprises a discardable frame assembly and a fixed load assembly, the size of the discardable frame assembly is larger, and the size of the fixed load assembly is smaller. In the embodiments of the present application, the marine equipment is divided into a first equipment and a second equipment, wherein the size of the second equipment is smaller than that of the first equipment.

[0044] Since the size of the first equipment is large, the entire area of the lifting body 210 is required to mount the first equipment. Since the plurality of first fixing members 221 are distributed around the lifting body 210 and connected to the outer circumferential surface of the lifting body 210, the first fixing members 221 do not occupy the area of the lifting body 210. Since the plurality of first fixing members 221 can abut the circumferential side of the first equipment, the first equipment can be fixed on the lifting body 210, and slipping of the first equipment during being lifted can be avoided as much as possible.

[0045] Please refer to Figure 1 and Figure 2In some embodiments, the fixing assembly 220 further comprises a plurality of second fixing members 222, which are arranged in the lifting body 210 and detachably connected with the lifting body 210. The plurality of second fixing members 222 enclose a mounting space 213 for mounting the second device, and can abut against the periphery of the second device to fix the second device to the lifting body 210. The size of the second device is smaller than that of the first device.

[0046] Since the size of the second device is smaller, it only occupies part of the area of the lifting body 210. If the second fixing members 222 are also arranged outside the lifting body 210, it is inconvenient to abut against the second device. Therefore, the plurality of second fixing members 222 are arranged in the lifting body 210, and the plurality of second fixing members 222 enclose the mounting space 213 for mounting the second device. The second device is mounted in the mounting space 213, and the second fixing members 222 can conveniently abut against the second device to fix it.

[0047] Since the second fixing members 222 are detachably connected with the lifting body 210, when the first device is lifted, the second fixing members 222 are detached from the lifting body 210 to not occupy the area of the lifting body 210. The first device is fixed by the plurality of first fixing members 221. When the second device is lifted, the plurality of second fixing members 222 are mounted to fix the second device. The area of the mounting space 213 can be set according to the size of the second device.

[0048] Please refer to Figure 3 In some embodiments, the first fixing members 221 and the second fixing members 222 each comprise a fixing portion 223, a fixing bolt 224 and an abutting plate 225. The fixing portion 223 is connected with the lifting body 210. The fixing bolt 224 is arranged in the fixing portion 223 and threadedly driven with the fixing portion 223. The abutting plate 225 is arranged at one end of the fixing bolt 224 close to the marine device. The fixing bolt 224 can drive the abutting plate 225 to abut against the marine device by threadedly driving with the fixing portion 223.

[0049] That is, the fixing portion 223 has an internal thread. After the marine device is mounted on the lifting body 210, an operator twists the fixing bolt 224 to threadedly drive the fixing bolt 224 with the fixing portion 223, so as to move in the direction close to the marine device until the abutting plate 225 abuts against the marine device. After the plurality of first fixing members 221 or the plurality of second fixing members 222 abut against the marine device from all around, the marine device can be fixed.

[0050] And, before lifting the ship equipment, the center of the ship equipment and the center of the mounting port can be aligned by the plurality of first fixing members 221 or the plurality of second fixing members 222, i.e. the ship equipment is slightly pushed by the fixing bolts 224 to align the center of the ship equipment and the center of the mounting port, so as to ensure that the ship equipment can smoothly enter the mounting port.

[0051] In some embodiments, the abutting plate 225 is provided with a gasket 226 near one end of the ship equipment, and the gasket 226 is used to abut the ship equipment.

[0052] Since the force generated by the threaded drive is large, in order to avoid damaging the ship equipment when the abutting plate 225 abuts the ship equipment as much as possible, the abutting plate 225 is provided with a gasket 226 near one end of the ship equipment, so that when the abutting plate 225 abuts the ship equipment, the gasket 226 contacts the ship equipment, and of course, the gasket 226 is made of flexible material. Specifically, the gasket 226 can be made of oil-resistant rubber.

[0053] Please refer to Figure 2 In some embodiments, the lifting body 210 includes a mounting frame 211 and two mounting rods 212, the two mounting rods 212 are crossly arranged in the mounting frame 211, the two mounting rods 212 have a cross point, and each of the two mounting rods 212 is provided with two second fixing members 222, and the two second fixing members 222 are respectively arranged at two ends of the cross point.

[0054] The mounting frame 211 can be rectangular, and the two mounting rods 212 are respectively connected to four corners of the mounting frame 211. The mounting frame 211 and the two mounting rods 212 can be made of I-beams, which have large bearing capacity and are relatively safe and stable. The two mounting rods 212 cross to form a cross point. Obviously, the cross region of the two mounting rods 212 has the highest strength, and the two second fixing members 222 on each of the two mounting rods 212 are respectively arranged at two ends of the cross point, so that the second equipment can be located in the cross region as much as possible, thereby making the installation of the second equipment more stable and improving the safety.

[0055] Please refer to Figure 4 In some embodiments, the lifting assembly 200 further includes a plurality of mounting members 230, the plurality of mounting members 230 are connected to the outer circumferential surface of the lifting body 210, the plurality of mounting members 230 are one-to-one corresponding to the plurality of first fixing members 221, and the first fixing members 221 are mounted on the corresponding mounting members 230.

[0056] It can be understood that the first device is arranged on the top of the lifting body 210, and thus the fixing bolt 224 for abutting against the first device is also arranged above the lifting body 210, and thus the fixing portion 223 also needs to be arranged on the top of the lifting body 210. Therefore, in order to facilitate the connection of the fixing portion 223 and the outer circumferential surface of the lifting body 210, a plurality of mounting members 230 are arranged on the outer circumferential surface of the lifting body 210, the mounting members 230 are fixedly connected with the lifting body 210, the plurality of mounting members 230 are arranged in one-to-one correspondence with the plurality of first fixing members 221, the first fixing members 221 are mounted on the corresponding mounting members 230, so that the first fixing members 221 are fixedly connected with the lifting body 210. Specifically, the mounting members 230 can be connected to the outer circumferential surface of the mounting frame 211 through connecting bolts.

[0057] The second fixing member 222 is arranged on the top surface of the lifting body 210, and thus the fixing portion 223 of the second fixing member 222 can be directly connected with the top surface of the lifting body 210. Specifically, the fixing portion 223 of the second fixing member 222 can also be connected with the lifting body 210 through connecting bolts, so as to facilitate disassembly and assembly.

[0058] Please refer to Figure 1 In some embodiments, the lifting device 10 further comprises a roller assembly 400 arranged on the bottom of the mounting assembly 100.

[0059] In the process of hoisting the ship equipment to the lifting assembly 200, in order to facilitate operation, the ship equipment is first hoisted to the lifting assembly 200 outside the ship, and then the lifting device 10 is moved to below the installation opening. However, the ship equipment is heavy, and thus in order to facilitate the movement of the lifting device 10, the roller assembly 400 is arranged on the bottom of the mounting assembly 100, that is, the lifting device 10 is moved through the roller assembly 400, so as to be more labor-saving and convenient.

[0060] Specifically, the roller assembly 400 comprises a plurality of rollers arranged at intervals, and the rollers can adopt load-bearing universal casters, so as to be able to bear the ship equipment. In order to facilitate the pushing of the lifting device 10 by the operating personnel, a handrail 500 for holding by the operating personnel can be arranged on the mounting assembly 100.

[0061] Please refer to Figure 1 and Figure 5 In some embodiments, the lifting mechanism 300 comprises a plurality of lifting members 310, the mounting assembly 100 comprises a mounting body 110 and a plurality of mounting seats 120 arranged on the mounting body 110, the plurality of mounting seats 120 are arranged in one-to-one correspondence with the plurality of lifting members 310, and the lifting members 310 are mounted in the corresponding mounting seats 120.

[0062] In order to make the lifting assembly 200 lift stably, the lifting mechanism 300 comprises a plurality of lifting pieces 310, the plurality of lifting pieces 310 drive the lifting assembly 200 together, can make the lifting assembly 200 lift stably, and keep horizontal, thereby further avoiding the ship equipment to slip.

[0063] Since the installation assembly 100 comprises the installation body 110 and the plurality of installation seats 120 arranged on the installation body 110, the plurality of installation seats 120 are arranged one by one with the plurality of lifting pieces 310, the lifting piece 310 is installed in the corresponding installation seat 120, thereby can make the lifting piece 310 install stably, not easy to displace.

[0064] Specifically, the lifting piece 310 can adopt a hydraulic oil cylinder. The installation body 110 and the lifting body 210 are both rectangular, the lifting piece 310 is provided with four, the four lifting pieces 310 are arranged at four corners of the installation body 110, and the driving end of the four lifting pieces 310 is connected to four corners of the lifting body 210, thereby can make the lifting force provided by the lifting piece 310 evenly distributed on the lifting assembly 200, make the lifting assembly 200 lift stably, and keep horizontal.
