Description

Technical Field

[0001] This utility model relates to the field of waterborne hoisting technology, specifically a modular floating crane. Background Art

[0002] Floating cranes are machines used for lifting operations on water. They are typically mounted on the deck of a box-shaped ship, with various types of cranes, mooring equipment, and living facilities. Small and medium-sized floating cranes are generally powered from shore, while self-propelled cranes require a propulsion system. In the construction of large bridges spanning rivers in China, when large-scale water-related operations are involved, floating cranes must be used for lifting operations. Because floating crane decks are often a single unit with a large area, and the operating environment of floating cranes is mostly in inland waterways, some of which are narrow and cannot be accessed by the floating crane hull, we have introduced a modular floating crane.

[0003] The existing technology has the following problems: most existing floating cranes are a single unit, and the floating cranes are mostly used in inland river basins, where some river channels are narrow and the floating crane hull cannot enter. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 8This utility model provides a technical solution: a splicing floating crane, including a first float 1 and a second float 2. The first float 1 is provided with locking components 3 on both sides. The second float 2 is fixedly connected to two locking pins 4 on both sides. The bottom surface of the second float 2 is fixedly connected with a float block 5. The float block 5 has a threaded hole 6 in the middle. The top surface of the second float 2 is fixedly connected with a corner block 7. The top surfaces of the first float 1 and the second float 2 are fixedly connected with a bottom plate 8. The top surface of the bottom plate 8 is provided with a lifting mechanism 9, and the middle of the bottom plate 8 is threadedly connected with a fastening bolt 10. The middle of the first float 1 is provided with a positioning component 11.

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 6-8 As shown, the locking assembly 3 includes a mounting shaft 301 fixedly connected to one side of the float 1. A locking housing 302 is rotatably connected to the middle of the mounting shaft 301. A gear 303 is rotatably connected inside the locking housing 302. A rack 304 meshes with one side of the gear 303. A locking hook 305 is provided at the end of the rack 304 away from the mounting shaft 301. After the three floats are pre-connected, the locking assembly 3 can further tighten the floats, tightly connecting the three floats, so that they can be completely fixed together by the fastening bolts 10 later.

[0029] In this embodiment, as Figure 1 and Figure 8 As shown, the locking hook 305 is hooked in the middle of the locking post 4, and a limiting piece is provided at the end of the locking post 4 away from the second float 2; this structure can prevent the locking hook 305 from slipping off the end of the locking post 4 and enhance the connection between the first float 1 and the second float 2.

[0030] In this embodiment, as Figure 7As shown, a rotating shaft 306 is fixedly connected to the middle of the side of gear 303 away from float plate 2. The rotating shaft 306 passes through the locking housing 302, ratchet 307, and protective housing 308 in sequence. A handle 309 is fixedly connected to the end of the rotating shaft 306 extending to the outside of the protective housing 308. A pawl 3010 is attached to the side of the ratchet 307. An adjusting shaft 3011 passes through the middle of the pawl 3010. The end of the adjusting shaft 3011 away from the pawl 3010 extends to the outside of the protective housing 308. The adjusting shaft 3011 is rotatably connected to the outside of the locking housing 302. The pawl 3010 is connected to the inner wall of the protective housing 308. A torsion spring 3012 is fixedly connected between the components. This structure can rotate the shaft 306 by rotating the handle 309. The shaft 306 will simultaneously drive the ratchet 307 and the gear 303 to rotate. The rotation of the gear 303 will drive the rack 304, which meshes with it, to move into the locking housing 302. This will drive the locking hook 305 at the end to pull the locking pin 4 towards the opposite side of the locking housing 302, making the float plate 1 and float plate 2 more tightly connected. The ratchet 307, pawl 3010 and torsion spring 3012 cooperate with each other to self-lock the gear 303 and prevent the rack 304 from loosening.

[0031] In this embodiment, as Figure 1 and Figure 2 As shown, the fastening bolt 10 passes through the base plate 8 and the second float plate 2 from top to bottom, and the bottom end of the fastening bolt 10 is threaded into the threaded hole 6 opened in the middle of the float block 5; this structure can fix the base plate 8 to the top surface of the first float plate 1 and the second float plate 2, and prevent the lifting mechanism 9 on the top of the base plate 8 from becoming loose.

[0032] In this embodiment, as Figure 3 and Figure 4 As shown, both sides of float plate 1 have two slots 101 and two inserts 102. The ends of the inserts 102 have two triangular blocks on each side. Float plate 2, on the side that adheres to float plate 1, also has two inserts 102 and two slots 101. The ends of the inserts 102 on the side of float plate 2 do not have triangular blocks. The slots 101 on the side of float plate 2 have two mounting grooves 201 on their inner walls compared to the slots 101 on the side of float plate 1. The mounting grooves 201 are internally fixedly connected. There is a spring 202, and a locking block 203 is fixedly connected to one end of the spring 202. The locking block 203 has a triangular structure, and the right-angled side of the locking block 203 is in close contact with the right-angled side of the triangular block at the end of the side insert block 102 of the float plate 1. This structure can pre-connect the two float plates 2 and the middle float plate 1 when splicing the floating crane, and use the triangular structure at the end of the insert block 102 to self-lock with the locking block 203 in the mounting groove 201 to prevent the float plates from loosening and making subsequent splicing inconvenient.

[0033] In this embodiment, as Figure 1 , Figure 3 and Figure 5 As shown, the positioning component 11 includes a groove 1101 formed in the middle of the float 1. A bidirectional screw 1102 is rotatably connected inside the groove 1101. Two positioning blocks 1103 are threadedly connected to the middle of the bidirectional screw 1102. A rotating rudder 1104 is provided at one end of the bidirectional screw 1102 extending to the outside of the groove 1101. During assembly, the bottom plate 8 can be placed on the top surface of the float 1, making it roughly parallel to the float 1. Then, the two floats 2 will move towards the middle float 1 from both sides. During this process, the corner blocks 7 on the top surface of the floats 2 will wrap around the corners of the bottom plate 8, thus initially positioning the bottom plate 8. Then, the rotating rudder 1104 is turned to drive the bidirectional screw 1102 to rotate. The bidirectional screw 1102 will drive the two positioning blocks 1103 to move closer to each other, automatically centering the bottom plate 8, so that the bottom plate 8 is finally in the middle position of the floating crane device, avoiding overturning due to uneven weight distribution.

[0034] The usage and advantages of this utility model: The working process of this modular floating crane is as follows:

[0035] First, insert the slot 101 on the side of the float plate into the adjacent float plate insert 102 that needs to be connected, and use the locking block 203 in the second float plate 2 insert 102 to lock it, thus realizing the pre-connection between the float plates. Then, use the locking component 3 to further strengthen the connection between the first float plate 1 and the second float plate 2, and rely on the self-locking of the locking component 3 to prevent the first float plate 1 and the second float plate 2 from loosening. When the two second float plates 2 move closer to the first float plate 1, the corner block 7 on the top surface of the second float plate 2 can push the bottom plate 8 towards the center of the first float plate 1. Then, use the positioning component 11 to center and position the bottom plate 8. After that, the fastening bolt 10 can be screwed into the threaded hole 6, thereby connecting the three bottom plates 8 and the float plates, completing the splicing of the floating crane.
