DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0022] The utility model provides Figures 1 to 4 A small lifting device for ship maintenance is shown, including a base 1, which has a semi-annular structure. A lower support column 2 is fixedly connected to the base 1, and an upper support column 3 is fixedly connected to the top of the lower support column 2. The base 1 can be set as a semi-annular structure to provide basic support for the equipment. At the same time, the lower support column 2 and the upper support column 3 are connected to each other to improve the overall strength of the equipment, thereby avoiding bending of the equipment due to the weight of the hoisted objects and causing damage to the equipment.

[0023] A guide rail assembly is provided on the lower support column 2, which can guide the lifting rope of the equipment to avoid contact between the rope and the equipment, reduce the life and strength of the rope, and at the same time limit the up and down movement of the hoisted objects to prevent the equipment from shaking due to the influence of the hoisted objects.

[0024] The guide rail assembly assists the operation of the wire rope 11 through the first guide wheel 7 and the second guide wheel 9, effectively preventing the rope from contacting the equipment during use, while improving the smoothness of the rope use.

[0025] The guide rail assembly includes two L-shaped plates 4, which are fixedly connected to the lower support column 2. The two L-shaped plates 4 are connected to a winding rod 5 on one side close to each other. A reciprocating motor 6 is fixedly connected to one of the L-shaped plates 4, and the output end of the reciprocating motor 6 is fixedly connected to the winding rod 5. A first guide wheel 7 is arranged on the upper support column 3, and an inclined plate 8 is fixedly connected to the top of the upper support column 3. A second guide wheel 9 is arranged on the inclined plate 8. A movable opening 10 is opened on the inclined plate 8. A steel wire rope 11 is wound on the winding rod 5, and one end of the steel wire rope 11 is movable. The bottom end of the wire rope 11 is fixedly connected with a load-bearing hook 12 through the movable opening 10. When working, the reciprocating motor 6 can be driven to make the winding rod 5 release or retract the rope according to the use requirements, and the first guide wheel 7 and the second guide wheel 9 have a limiting effect on the movement of the wire rope 11 to avoid misalignment during the movement. At the same time, the first guide wheel 7 and the second guide wheel 9 have a guiding limit on the contraction of the wire rope 11 to avoid the wire rope 11 from shaking left and right when hoisting objects, thereby enhancing the directionality of the contraction of the wire rope 11.

[0026] During specific use, the first guide wheel 7 and the second guide wheel 9 are a combination of a fixing member and a guide wheel, wherein the fixing member is fixed on the equipment, and the guide wheel guides the wire rope 11. At the same time, the guide wheel can effectively enhance the smoothness of the contraction of the wire rope 11 to avoid jamming during contraction.

[0027] Furthermore, the steel wire rope 11 is respectively fitted with the first guide wheel 7 and the second guide wheel 9, so as to increase the service life of the steel wire rope 11, avoid friction breakage, and enhance the use strength of the steel wire rope 11.

[0028] Furthermore, both sides of the inner wall of the movable opening 10 are chamfered, which can protect the steel wire rope 11 from shrinking, and the movable opening 10 can lift and lower the steel wire rope 11 in a directional manner.

[0029] The base 1 is provided with a plurality of mounting holes, each of which is provided with a mounting bolt 17. The plurality of mounting bolts 17 can facilitate the installation and use of the device, and are conducive to subsequent disassembly and assembly operations, providing basic use functions of the device.

[0030] refer to Figure 3 In the figure, the inner walls on both sides of the base 1 are fixedly connected with a connecting plate 13, and a first movable part 14 is fixedly connected to the connecting plate 13. A second movable part 15 is fixedly connected to a side of the lower support column 2 close to the connecting plate 13. A reinforcement plate 16 is commonly arranged between the second movable part 15 and the first movable part 14. When working, the reinforcement plate 16 can enhance the stability of the device, enhance the supporting strength of the device, and tilt the lower support column 2 against it.

[0031] During specific use, the reinforcing plate 16 can move between the first movable member 14 and the second movable member 15 on both sides, and can also provide support for the device when the device is tilted.

[0032] Furthermore, a triangular support structure is formed between the base 1, the lower support column 2, and the reinforcement plate 16, thereby strengthening the supporting stability effect of the equipment by forming a triangular structure.

[0033] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
