According to a further optimization scheme of the technical scheme, the suspension arm is provided with a hydraulic nut rolling device.
According to a further optimization scheme of the technical scheme, the other end of the balance hanging beam is vertically provided with a clamping arm, a clamping adjusting rod is arranged at the lower part of the clamping arm, and the clamping adjusting rod and the balance hanging beam are arranged in parallel.
According to a further optimization scheme of the technical scheme, the adjustable lifting lug is provided with a locking nut.
According to a further optimized scheme of the technical scheme, the suspension arm, the clamping arm and the balance suspension beam are fixedly connected through fastening nuts; the support rod and the suspension arm are also fixedly connected through a fastening nut, and the clamping adjusting rod and the clamping arm are also fixedly connected through a fastening nut.
According to a further optimization scheme of the technical scheme, the clamping wheels are arranged at the inner side ends of the clamping adjusting rods.
The LNGC ship hydraulic nut handling device has the advantages of simple structure, strong bearing capacity, good matching performance and the like, can be widely applied to the dismounting of the hydraulic nuts of the propellers of different models of various ships, and can also be used for dismounting the hydraulic nuts of other equipment.
Drawings
Fig. 1 is a configuration diagram of a hydraulic nut handling apparatus for an LNGC-based ship according to a preferred embodiment in a use state.
Detailed Description
Referring to fig. 1, the LNGC type ship hydraulic nut handling device comprises a balance hanging beam 1, wherein an adjustable lifting lug 4 is sleeved on the balance hanging beam 1, and the adjustable lifting lug 4 is fixed with the balance hanging beam 1 in a relative position through a locking nut 41.
Two ends of the balance hanging beam 1 are respectively and vertically fixed with a clamping arm 2 and a hanging arm 3 through fastening nuts, and the clamping arm 2 and the hanging arm 3 are arranged in parallel.
The lower part of the suspension arm 3 is fixed with a support rod 31 through a fastening nut, the support rod 31 and the balance suspension beam 1 are arranged in parallel, and a support roller 32 is sleeved on the support rod 31.
The suspension arm 3 is provided with a hydraulic nut rolling device 33, the hydraulic nut rolling device 33 is used for assisting the hydraulic nut 5 to rotate, and a common transmission mechanical structure is adopted.
And a clamping adjusting rod 21 is arranged at the lower part of the clamping arm 2, and the clamping adjusting rod 21 and the balance hanging beam 1 are arranged in parallel. A clamping wheel 22 is arranged at the inner side end of the clamping adjusting rod 21. The clamping wheel 22 is used for fixing the hydraulic nut 5.
The clamping arm 2, the suspension arm 3 and the balance suspension beam 1 are fixed by fastening nuts, so that the balance suspension beam 1 with different lengths can be conveniently replaced and further matched with hydraulic nuts 5 with different specifications, and the supporting rod 31 and the suspension arm 3 are fixed by fastening nuts, so that the supporting rod 31 with different lengths can be conveniently replaced and further matched with the hydraulic nuts 5 with different specifications.
The specific application method of the hydraulic nut handling device for the LNGC ship is as follows.
1. When the hydraulic nut 5 is detached, the hydraulic nut 5 is screwed out by one third in advance.
2. Then, the hand chain block is used for hoisting the LNGC ship hydraulic nut handling device, and the support roller 32 is used for supporting the hydraulic nut 5.
3. The adjustable lug 4 of regulation finds out the focus of hydraulic nut 5, recycles chain block and holds up hydraulic nut 5 a little, is favorable to hydraulic nut 5 light to back out like this. The weight of the hydraulic nut is pressed on the tail shaft, so that the hydraulic nut is relatively laborious to rotate, and the hydraulic nut can be easily unscrewed after being slightly lifted by using the LNGC type ship hydraulic nut assembling and disassembling device.
4. Before the hydraulic nut 5 is completely unscrewed, the support rollers 32 are made to completely hold the hydraulic nut 5, and the clamp roller 22 is pressed against the end surface of the hydraulic nut 5 by the clamp adjustment lever 21 to prevent the hydraulic nut 5 from falling down when being unscrewed.
5. After the hydraulic nut is completely screwed out, the hydraulic nut 5 is descended by using the chain block and placed on the ground.
6. The hydraulic nut mounting process is operated as above, the hydraulic nut 5 is hoisted and fixed by the LNGC ship hydraulic nut handling device, then the hydraulic nut 5 is lifted to the mounting height of the tail shaft, and finally the hydraulic nut is screwed into the tail shaft.
This scheme hydraulic nut dismounting device adopts the form equipment that the nut is fixed to form by a plurality of parts, and bolted connection back whole structure bearing capacity is stronger, and a plurality of adjusting device can be applied to not equidimension hydraulic nut's installation. In addition, the tool has high safety performance, simple operation and wide use space, and can be widely applied to the disassembly and assembly of hydraulic nuts of various types.
