[0031] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0032] See also Figure 1-Figure 8 As shown, the utility model provides a lifting device for ship maintenance, including a gantry body 1 and a winch body 5, the gantry body 1 is provided with a plurality of winch bodies 5 and arranged in the same longitudinal direction, the horizontal parts on the top of the gantry body 1 are all arranged horizontally and the bottom surface is installed with a transverse adjustment component 2, specifically, the transverse adjustment component 2 includes a slide plate 201 and a sleeve 202, the slide plates 201 are fixed laterally between the tops of the vertical parts on both sides of the gantry body 1, the two sides of the slide plate 201 are laterally inserted with the sleeve 202 in a sliding fit manner, and the bottom surface of the sleeve 202 is detachably connected with a mounting plate 4 through a disassembly and assembly assembly 3, the purpose of such a setting is that the transverse position of the winch body 5 can be adjusted by the sleeve 202 of the transverse adjustment component 2 sliding laterally along the slide plate 201, and then the winch body 5 can be adjusted to the upper side of the hanging position of the ship hull by adjusting the transverse position of the winch body 5, so as to facilitate the adaptive adjustment of the hanging position according to the width of the ship hull.

[0033] See also Figure 1-Figure 5As shown, both sides of the bottom of the lateral adjustment component 2 are detachably connected with a flat mounting plate 4 through a disassembly assembly component 3, and the bottom surface of the mounting plate 4 is fixedly installed with a winch body 5 for lifting and lowering the ship. Specifically, the disassembly assembly component 3 includes a matching seat 304 and a fixing sleeve 301, the front and rear positions of the top surface of the mounting plate 4 are vertically fixed with matching seats 304, and the outer end surfaces of the matching seats 304 at the front and rear positions that are away from each other are longitudinally provided with locking holes 307, the front and rear positions of the bottom surface of the sliding sleeve 202 are vertically fixed with fixing sleeves 301, the bottom surface of the fixing sleeve 301 is vertically provided with matching grooves 303, and the matching grooves 303 and the matching seats 304 are vertically slidably matched one by one, the outer end surfaces of the fixing sleeves 301 at the front and rear positions that are away from each other are longitudinally provided with matching through holes 306, and the matching through holes 306 and the locking holes 307 are longitudinally provided. 07 are respectively longitudinally coaxially compared, the matching through holes 306 are coaxially detachably inserted with locking rods 305, and the inner ends of the locking rods 305 at the front and rear positions that are close to each other are coaxially detachably matched with the corresponding locking holes 307. The purpose of such a setting is that the mounting plate 4 and the winch body 5 can be detachably fixed to the bottom of the sliding sleeve 202 by means of the vertical sliding match between the matching seat 304 and the matching groove 303 and the longitudinal coaxial match between the locking rod 305 and the locking hole 307 through the matching through hole 306. At the same time, the matching seat 304 can be vertically slid out of the matching groove 303 only after the locking rod 305 is successively disengaged from the locking hole 307 and the matching through hole 306, so that the mounting plate 4 and the winch body 5 can be detached from the bottom of the sliding sleeve 202. The combination and disassembly method of the mounting plate 4 and the winch body 5 at the bottom of the sliding sleeve 202 is simple and easy to operate.

[0034] See also Figure 1-Figure 5 As shown, the lateral adjustment component 2 and the disassembly and assembly component 3 are optimized as follows. Specifically, as for the lateral adjustment component 2, the outer bottoms of the sliding sleeves 202 at both sides are horizontally extended and fixed with wing plates 203 away from each other. The wing plates 203 are vertically interspersed with clamping studs 205 in a threaded manner. The tops of the clamping studs 205 are coaxially fixed with elastic clamping blocks 204, and the elastic clamping blocks 204 can be pressed against the bottom surface of the slide plate 201. The bottoms of the clamping studs 205 are coaxially fixed with end heads 206 for convenient force application and twisting. After the winch body 5 is adjusted to a suitable hanging position by sliding the sleeve 202 along the slide plate 201, the elastic pressure block 204 can be pressed against the bottom surface of the slide plate 201 by twisting the end 206 with the help of a wrench or other tools, and then the sliding sleeve 202 can be locked and prevented from sliding naturally along the slide plate 201 by pressing the elastic pressure block 204 against the bottom surface of the slide plate 201, thereby locking and limiting the lateral position of the winch body 5 during use, preventing the winch body 5 from lateral movement during the process of lifting a small ship.

[0035] At the same time, optionally, the elastic pressure blocks 204 are all cylindrical rubber blocks and the outer diameters are smaller than the outer diameters of the corresponding clamping studs 205. The bottom surfaces of the end caps 206 are coaxially provided with inner hexagonal grooves. The bottom surfaces of the vertical parts on both sides of the gantry body 1 are horizontally extended and fixed with fixing seats 101, and the four corners of the fixing seats 101 are vertically provided with connecting through holes 102. Such a configuration first facilitates the elastic pressure blocks 204 to be elastically pressed on the bottom surface of the slide plate 201 to prevent the elastic pressure blocks 204 from damaging the bottom surface of the slide plate 201. At the same time, the hexagonal grooves are provided at the end caps 206 to facilitate the tightening and loosening of the clamping studs 205 with the help of outer hexagonal straight rod tools, which is convenient for operation under the gantry body 1. In addition, the gantry can be firmly and securely fixed in the setting position by installing bolts to the ground position through the connecting through holes 102 of the fixing seats 101. Further optionally, the cross-sectional shapes of the slide plate 201 and the sliding sleeve 202 along the longitudinal vertical plane are both rectangular, so that the sliding sleeve 202 has a good guiding and correcting design when sliding laterally along the slide plate 201.

[0036] Specifically for the disassembly and assembly assembly 3, the cross-sectional shapes of the mating seat 304 and the mating groove 303 along the horizontal vertical plane are both rectangular, so that the mating seat 304 has a good positioning and guiding design when it slides vertically along the mating groove 303. At the same time, the mating grooves 303 are all blind grooves in the vertical direction and are opened from bottom to top, and the top ends of the mating seats 304 are in close contact with the top ends of the corresponding mating grooves 303. With this arrangement, in the process of the mating seat 304 sliding vertically along the mating groove 303, when the locking hole 307 slides vertically with the mating seat 304 to be coaxial with the locking rod 305, an obvious prompt can be given by the way that the top ends of the mating seat 304 are in close contact with the top ends of the corresponding mating grooves 303. Optionally, the locking rods 305 are all screws, the matching through holes 306 and the locking holes 307 are all threaded holes, and the locking rods 305 are coaxially detachably connected with the matching through holes 306 and the locking holes 307 by means of threaded matching. Such a configuration facilitates the locking rods 305 to be able to be quickly assembled and disassembled with the matching through holes 306 and the locking holes 307 by twisting. Furthermore, the outer ends of the locking rods 305 at the front and rear positions that are away from each other are coaxially fixed with a handle 302 for easy holding, so that the locking rods 305 can be driven to move axially by applying force by holding the handle 302.

[0037] With the above structure, specifically in the process of maintaining and using a small vessel, the small vessel is towed ashore and towed to the positions on both sides of the gantry body 1. At least two gantry bodies 1 should be provided so that the bow and stern of the small vessel are respectively located below the horizontal part of the gantry body 1 at the front and rear positions. Then, in the process of lifting the small vessel, the lateral position of the winch body 5 can be adjusted by sliding the sleeve 202 of the lateral adjustment component 2 along the slide plate 201 laterally. Then, by adjusting the lateral position of the winch body 5, the winch body 5 can be adjusted to the position above the hanging position on the side of the ship's hull, thereby facilitating adaptive adjustment of the hanging position according to the width of the ship's hull, thereby improving flexibility and applicability during use. Specifically, when performing the combination and disassembly operations of the mounting plate 4, the winch body 5 and the sleeve 202, when they are combined, the winch body 5 can be adjusted by adjusting the lateral position of the winch body 5. The vertical sliding cooperation between the seat 304 and the matching groove 303 and the longitudinal coaxial cooperation between the locking rod 305 and the matching through hole 306 and the locking hole 307 can removably fix the mounting plate 4 and the winch body 5 to the bottom of the sliding sleeve 202. The fixing combination method of the mounting plate 4 and the winch body 5 at the bottom of the sliding sleeve 202 is simple and easy to operate, which makes it convenient to quickly combine the mounting plate 4 and the winch body 5 at the bottom of the sliding sleeve 202 for lifting the ship. When performing the disassembly operation, it is only necessary to hold the handle 302 and apply force to make the locking rod 305 disengage from the locking hole 307 and the matching through hole 306 in turn, so that the matching seat 304 can be vertically slid out of the matching groove 303, so that the mounting plate 4 and the winch body 5 can be disassembled from the bottom of the sliding sleeve 202. The disassembly method of the mounting plate 4 and the winch body 5 at the bottom of the sliding sleeve 202 is simple and easy to operate, which makes it convenient to disassemble the mounting plate 4 and the winch body 5 for inspection and maintenance.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
