[0042] The integrated cage fixing device provided by the embodiment of the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0043] Referring to Figure 1 , the structure schematic diagram of the integrated cage fixing device 100 of the embodiment of the present application is shown, like Figure 1As shown, the integrated cage fixing device 100 provided by the present application can include a base 10, a lifting assembly 20, a rotating shaft 30, a tension spring assembly 40, a transmission mechanism 50, a rotating screw 60, two clamping portions 70, and a suction assembly 80.

[0044] In actual application, the base 10, as the basis of the integrated cage fixing device 100, can be used to be connected with the ship body, and the bottom of the base 10 can be fixedly connected on the deck of the ship body by anchoring or welding, etc. Figures 3 to 5 As shown, the top of the base 10 is provided with a first recess 11 and a second recess 13 at positions corresponding to the rotating shaft 30 and the rotating screw 60, so as to ensure that the rotating shaft 30 and the rotating screw 60 can normally rotate.

[0045] Specifically, the lifting assembly 20 can be used as the driving mechanism of the whole fixing device, and the lifting assembly 20 includes a first telescopic rod 21, a second telescopic rod 23, and a connecting rod 22. The first telescopic rod 21 is connected to the first recess 11 in a lifting manner, the second telescopic rod 23 is connected to the second recess 13 in a lifting manner, and the two ends of the connecting rod 22 are fixedly connected with the first telescopic rod 21 and the second telescopic rod 23, respectively. The connecting rod 22 can be lifted synchronously with the first telescopic rod 21 and drive the second telescopic rod 23 to lift. The tension spring 41 is fixedly connected to the first telescopic rod 21, and the suction assembly 80 is fixedly connected to the second telescopic rod 23.

[0046] The first recess 11 includes a first sub-recess and a second sub-recess on both sides of the first telescopic rod 21, and a first boss 12 is formed between the first sub-recess and the second sub-recess. The bottom of the first telescopic rod 21 is fixedly connected to the first boss 12, and the top of the first telescopic rod 21 can be away from or close to the first boss 12 during the lifting process of the first telescopic rod 21. The first boss 12 is protruding relative to the first recess 11, and the top of the first boss 12 can be in the same plane as the top of the base 10.

[0047] The rotating shaft 30 is arranged along the length direction of the first recess 11, and both ends thereof are penetrating through the inner wall of the first recess 11 and are rotatably connected with the inner wall of the first recess 11. Specifically, the first boss 12 can be provided with a mounting hole, the axial direction of the mounting hole is the same as the axial direction of the rotating shaft 30, and the hole diameter of the mounting hole is greater than the diameter of the rotating shaft 30. A bearing can be fixedly arranged in the mounting hole, the diameter of the inner ring of the bearing is matched with the diameter of the rotating shaft 30, the outer ring of the bearing is fixedly connected with the mounting hole, and the rotating shaft 30 is arranged in the inner ring of the bearing.

[0048] One end of the tension spring assembly 40 is fixedly connected to the end of the first telescopic rod 21 away from the first recess 11, and the other end thereof is arranged around the end of the rotating shaft 30 away from the first telescopic rod 21.

[0049] Specifically, the tension spring assembly 40 comprises a tension spring 41, one end of which is fixedly connected to the top of the first telescopic rod 21, and the other end is arranged around the rotating shaft 30. During the lifting of the first telescopic rod 21, the tension spring 41 is subjected to an axial tension and stores energy. When the first telescopic rod 21 is lowered, the restoring force of the tension spring 41 can drive the rotating shaft 30 to rotate through the end of the tension spring 41 arranged around the rotating shaft 30.

[0050] The rotating screw 60 is arranged along the length direction of the second groove 13, and both ends thereof pass through the inner wall of the first groove 11 and are rotationally connected with the inner wall of the second groove 13. The rotating screw 60 is in transmission connection with the rotating shaft 30, and in the case that the rotating shaft 30 is driven to rotate by the tension spring 41, the rotating screw 60 can also rotate simultaneously. It should be noted that, similar to the mounting mode of the rotating shaft 30, the second groove 13 comprises a third sub-groove and a fourth sub-groove on both sides of the second telescopic rod 23, and the second boss 14 is formed between the third sub-groove and the fourth sub-groove. One end of the rotating screw 60 is in transmission connection with the rotating shaft 30 and penetrates the second boss 14 along the length direction. The part of the rotating screw 60 located in the second boss 14 can rotate relative to the second boss 14 through a bearing, so that the rotating shaft 30 can rotate relative to the base 10. Similarly, the second boss 14 is protruded relative to the second groove 13, and the top thereof can be located in the same plane as the top of the base 10.

[0051] The transmission mechanism 50 is connected between the rotating screw 60 and the rotating shaft 30, so as to drive the rotating screw 60 to rotate under the rotation of the rotating shaft 30.

[0052] The rotating screw 60 is provided with two clamping portions 70 in screw connection with the rotating screw 60. The two clamping portions 70 are arranged at intervals on both sides of the second telescopic rod 23. In the case that the rotating screw 60 rotates, since the two clamping portions 70 are in screw connection with the rotating screw 60, the two clamping portions 70 can move relative to the rotating screw 60. In the embodiment of the present application, the moving directions of the two clamping portions 70 are opposite to each other so as to be able to move close to or away from each other. As shown in FIG. 7, the two clamping portions 70 are in the state of moving away from each other. As shown in FIG. 8, the two clamping portions 70 are in the state of moving close to each other. Figure 3 Figure 4

[0053] ​​In actual application, the integrated sleeve cage 200 includes a plurality of ring beams 201 arranged in parallel along the height direction and a plurality of blocking rods 202 for connecting the plurality of ring beams 201, the number of the blocking rods 202 is multiple, the plurality of blocking rods 202 are arranged in the circumferential direction of the ring beams 201 at intervals, and the blocking rods 202 are axially consistent with the ring beams 201. The integrated sleeve cage 200 is located between the two clamping parts 70, and in the case that the two clamping parts 70 are close to each other, the two clamping parts 70 can clamp the blocking rods 202 of the integrated sleeve cage 200 and realize the fixation of the integrated sleeve cage 200, and in the case that the two clamping parts 70 are away from each other, the two clamping parts 70 can release the fixation of the integrated sleeve cage 200, so that the integrated sleeve cage 200 can be lifted away from the fixing device and transferred to the installation position on the sea.

[0054] The adsorption assembly 80 is fixedly connected to the second telescopic rod 23 and located between the two clamping parts 70, the ring beams 201 of the integrated sleeve cage 200 are steel structures, and the adsorption assembly 80 can generate an adsorption force for adsorbing the ring beams 201 at the bottom of the integrated sleeve cage 200.

[0055] In actual application, when the integrated sleeve cage 200 is transported, the operator needs to first lift the integrated sleeve cage 200 to the ship body through the lifting device, and in the lifting process, the integrated sleeve cage 200 will shake to different degrees, so it is difficult to be placed stably and accurately at the target position of the fixing device. The adsorption assembly 80 provided in the embodiment of the application can generate an adsorption force on the bottom ring beam 201 during the lifting of the integrated sleeve cage 200, so as to adsorb the integrated sleeve cage 200 to the adsorption assembly 80, and prevent the shaking of the sleeve cage during lifting from affecting the lifting efficiency and effect.

[0056] In an alternative embodiment of the application, the internal thread directions of the two clamping parts 70 are opposite, so as to have opposite movement directions in the case that the rotating screw rod 60 rotates.

[0057] In the embodiment of the application, the two clamping parts 70 are provided on both sides of the lifting assembly 20, and since the two clamping parts 70 need to move towards each other to clamp the integrated sleeve cage 200, in the case that the rotating screw rod 60 has only one thread direction along the length direction, the internal thread directions of the two clamping parts 70 are set to be opposite, so that the two clamping parts 70 have opposite movement directions.

[0058] In another alternative embodiment of the application, the rotating screw rods 60 on both sides of the second telescopic rod 23 have different thread directions, so that the two clamping parts 70 have opposite movement directions in the case that the rotating screw rod 60 rotates.

[0059] In actual application, when the two clamping portions 70 have the same internal thread direction, the external thread direction of the rotating screw rod 60 on both sides of the second boss 14 is set to be opposite, so that the two clamping portions 70 also have opposite movement directions.

[0060] Optionally, the lifting assembly 20 further comprises a driving motor, which is in transmission connection with the first telescopic rod 21 to drive the first telescopic rod 21 to lift.

[0061] Specifically, the first telescopic rod 21 can be an electric telescopic rod, and a motor mounting cavity can be arranged in the base 10 to mount the driving motor. The driving motor is in electrical connection with the first telescopic rod 21 to electrically drive the first telescopic rod 21 to realize the lifting function. The second telescopic rod 23 can be connected with the first telescopic rod 21 through the connecting rod 22, so as to realize the lifting function by following the lifting of the first telescopic rod 21. In actual application, the lifting of the first telescopic rod 21 can pull the tension spring 41 and drive the rotating shaft 30 to rotate. The lifting of the second telescopic rod 23 can make the adsorption assembly 80 close to the bottom of the integrated cage 200, so as to facilitate the adsorption of the adsorption assembly 80 to the bottom ring beam 201 of the integrated cage 200. During the descending of the first telescopic rod 21, the second telescopic rod 23 follows the first telescopic rod 21 to descend. At this time, since the adsorption assembly 80 has completed the adsorption to the bottom ring beam 201 of the cage, the shaking amplitude of the integrated cage 200 during hoisting and descending can be reduced, so that the cage can be stably and accurately lowered to the target position of the fixing device.

[0062] In addition, the first telescopic rod 21 and the second telescopic rod 23 can also be electric telescopic rods, and are independently driven to lift. At this time, the connecting rod 22 can not be arranged, or the connecting rod is arranged in a flexible structure, and two ends of the connecting rod are connected with the first telescopic rod 21 and the second telescopic rod 23 respectively, so as to limit the first telescopic rod 21 and the second telescopic rod 23 from moving away from each other within a certain range without affecting the independent lifting of the two, and to ensure the overall stability of the lifting assembly 20 during lifting.

[0063] In an embodiment of the present application, the tension spring assembly 40 comprises a tension spring 41 and a fixed sleeve ring 42. The fixed sleeve ring 42 is a ring structure matched with the top structure of the first telescopic rod 21, and the fixed sleeve ring 42 is fixedly sleeved on the top of the first telescopic rod 21 to facilitate the fixation of the tension spring 41. The other end of the tension spring 41 is wound on the end of the rotating shaft 30. Under the action of the restoring force, the part of the tension spring 41 wound on the end of the rotating shaft 30 is released from the winding on the rotating shaft 30, so that the rotating shaft 30 can rotate axially.

[0064] Further, the end of the rotating shaft 30 can be fixedly connected with a rotating wheel 31, the rotating wheel 31 is provided with a limiting plate on both axial sides, and the tension spring 41 is arranged between the limiting plates on both sides of the rotating wheel 31. It can be understood that when the tension spring 41 is arranged around the rotating shaft 30, the tension spring 41 can move axially along the rotating shaft 30 under the force. The rotating wheel 31 is fixedly connected with the rotating shaft 30, and the tension spring 41 is arranged between the limiting plates on both sides of the rotating wheel 31, so that the movement of the end of the tension spring 41 axially along the rotating shaft 30 is limited, and the normal work of the tension spring 41 is ensured.

[0065] In an embodiment of the present application, the adsorption assembly 80 comprises a suction disc 81 and at least two suction claws 82, the suction disc 81 is a circular disc structure, the suction claw 82 comprises an angle arranged long rod and short rod, the suction disc 81 is fixedly connected with the first telescopic rod 21, the suction claw 82 is arranged at least partially along the radial direction of the suction disc 81, and the at least two suction claws 82 are uniformly spaced along the circumferential direction of the suction disc 81. Specifically, the suction disc 81 is fixedly connected at the top of the second telescopic rod 23, the long rod part of the suction claw 82 is arranged along the radial direction of the suction disc 81 and connected with the suction disc 81. In an example embodiment of the present application, four suction claws 82 are provided, and in actual application, the number of suction claws can also be five, six, seven, eight, etc., which is not limited in the present application.

[0066] It should be noted that the integrated cage 200 generally has large volume and weight, in order to meet the adsorption of the bottom ring beam 201 of the integrated cage 200, the suction disc 81 can also have a large weight, and the suction disc 81 is connected with the lifting assembly 20, which needs to support the synchronous lifting of the suction disc 81 during lifting. The adsorption assembly 80 is provided as a combination of the suction disc 81 and the suction claw 82, and the overall weight of the adsorption assembly 80 can be reduced due to the rod structure of the suction claw 82, so that the lifting assembly 20 can complete the lifting operation under the action of a smaller driving force. At the same time, the suction claw 82 can also provide adsorption force, which can work together with the suction disc 81 to achieve adsorption.

[0067] In an embodiment of the present application, the suction claw 82 comprises a supporting part 821 and a limiting part 822 arranged at a preset angle, wherein the supporting part 821 is arranged along the radial direction of the suction disc 81 and connected with the suction disc 81, and the limiting part 822 is arranged along the axial direction of the suction disc 81 and extends towards the direction away from the base 10.

[0068] The supporting part 821 is a long rod structure, and the limiting part 822 is a short rod structure. The supporting part 821 is arranged along the radial direction of the suction disc 81 and is connected to the suction disc 81, and cooperates with the suction disc 81 to support and support the integrated cage 200. The limiting part 822 is arranged at an angle with the supporting part 821 and extends away from the base 10. When the suction disc 81 adsorbs the bottom ring beam 201 of the cage, the limiting part 822 can limit the displacement of the bottom ring beam 201 of the cage along the radial direction of the suction disc 81, so as to avoid the integrated cage 200 from separating from the suction disc 81 during hoisting and lowering. In actual application, the distance between the limiting part 822 and the center of the suction disc 81 can be greater than the diameter of the bottom ring beam 201 of the integrated cage 200.

[0069] In the embodiment of the present application, the transmission mechanism 50 includes a driving wheel 51, a driven wheel 53, and a transmission belt 52 sleeved on the driving wheel 51 and the driven wheel 53. Specifically, the driving wheel 51 is fixedly connected to the end of the rotating shaft 30, the driven wheel 53 is fixedly connected to the end of the rotating screw 60, the driving wheel 51 rotates synchronously with the rotating shaft 30 under the rotation of the rotating shaft 30, the transmission belt 52 rotates synchronously, and the driven wheel 53 rotates in the same direction under the action of the transmission belt 52. Since the rotating screw 60 is fixedly connected to the driven wheel 53, the rotation of the driven wheel 53 can drive the rotation of the rotating screw 60.

[0070] It should be noted that the transmission mechanism 50 in the embodiment of the present application is only an example, and in actual application, the transmission mechanism 50 is not limited to the above-mentioned transmission mode provided in the embodiment of the present application. The transmission connection between the rotating shaft 30 and the rotating screw 60 can also adopt other forms of transmission structure, such as double gear transmission and the like, which can also achieve the transmission between the rotating shaft 30 and the rotating screw 60.

[0071] In an embodiment of the present application, the clamping part 70 includes a sliding block 71 and a clamping arm 72, the clamping arm 72 is fixedly connected to the sliding block 71, and the sliding block 71 is threadedly connected to the rotating screw 60.

[0072] Specifically, each clamping part 70 includes one sliding block 71 and one clamping arm 72. The sliding block 71 is used to move axially along the rotating screw 60, and the clamping arm 72 is used to clamp and fix the cage or release the fixation of the cage. The sliding block 71 is provided with a screw hole axially aligned with the rotating screw 60, and the inner wall of the screw hole is provided with an internal thread. The internal thread of the sliding block 71 is matched with the external thread of the rotating screw 60. Under the rotation of the rotating screw 60, the two sliding blocks 71 move on the rotating screw 60 and drive the two clamping arms 72 to move closer to or away from each other. Since the integrated cage 200 is connected to the lifting assembly 20, and the lifting assembly 20 is arranged between the two clamping arms 72, the two clamping arms 72 moving closer to or away from each other can realize the fixation or release of the fixation of the integrated cage 200.

[0073] Further, referring to Figure 2 The clamping arm 72 can include a clamping rod 721, a fastener 722, and a snap ring 723, wherein the clamping rod 721 is axially aligned with the sleeve cage, the clamping rod 721 is provided with a mounting hole, the mounting hole is arranged along the radial direction of the clamping rod 721, and the axial direction of the mounting hole is preferably aligned with the axial direction of the rotary screw 60. The fastener 722 is arranged in the mounting hole, and the snap ring 723 is fixedly connected to one side of the fastener 722 close to the adsorption assembly 80. In actual application, when the clamping arm 72 is close to the integrated sleeve cage 200, the snap ring 723 can abut against the stopper 202 of the integrated sleeve cage 200, and the snap rings 723 on the two clamping arms 72 are arranged oppositely to clamp and fix the integrated sleeve cage 200 from both sides.

[0074] Optionally, the number of fasteners 722 is multiple, and the multiple fasteners 722 are arranged at intervals along the axial direction of the clamping rod 721. Each fastener 722 is provided with a snap ring 723 matched with the stopper 202.

[0075] In actual application, the integrated sleeve cage 200 can include multiple parallel arranged ring beams 201, multiple rows of stoppers 202 between the multiple ring beams 201, multiple fasteners 722, and one snap ring 723 arranged for each fastener 722, which can enhance the clamping effect of the clamping arm 72 on the stopper 202, thereby ensuring the fixing effect on the integrated sleeve cage 200.

[0076] The snap ring 723 includes an inner wall and an outer wall arranged away from each other, wherein the inner wall is in an arc structure and is used to abut against the stopper 202 of the integrated sleeve cage 200, and the curvature of the arc structure is matched with the curvature of the outer wall of the stopper 202 of the integrated sleeve cage 200. It can be understood that when the curvature of the inner wall of the snap ring 723 is matched with the curvature of the outer wall of the stopper 202 of the sleeve cage, the contact area of the snap ring 723 and the stopper 202 can be maximized, and the clamping effect of the clamping arm 72 on the integrated sleeve cage 200 can be improved.

[0077] In an embodiment of the present application, the snap ring 723 further includes an anti-skid pad fixedly connected to the inner wall of the snap ring 723.

[0078] Specifically, the anti-skid pad can be bonded to the inner wall of the clasp ring 723, and the anti-skid pad can be made of silica gel, rubber or the like, which is not limited in the present application. In the case that the anti-skid pad is attached to the outer wall of the stop rod 202, the direct contact between the inner wall of the clasp ring 723 and the outer wall of the stop rod 202 can be avoided, the friction between the clasp ring 723 and the stop rod 202 is enhanced, and the clamping stability is improved. In addition, since the size of the stop rod 202 and the clasp ring 723 can not be completely matched, the stop rod 202 can be displaced relative to the clasp ring 723, therefore, the anti-skid pad can be made of a flexible material with a certain elasticity, when the clasp ring 723 clamps the stop rod 202, the anti-skid pad can be deformed by a certain amount, and when the anti-skid pad recovers from the deformation, the gap between the clasp ring 723 and the stop rod 202 can be reduced, and the fixing effect between the integrated cage 200 and the integrated cage fixing device 100 is enhanced.

[0079] In summary, the integrated cage fixing device provided by the embodiments of the present application has at least the following advantages:

[0080] In the embodiments of the present application, when the lifting assembly rises relative to the base, the tension spring is subjected to an axial tension and stores energy, when the lifting assembly descends, the tension spring releases the stored energy and drives the rotating shaft to rotate under the action of the restoring force, the rotation of the rotating shaft drives the rotating screw to rotate synchronously, the two clamping parts are threadedly connected with the rotating screw and have opposite movement directions, so they can move closer to or farther away from each other under the rotation of the rotating screw, and the integrated cage is arranged between the two clamping parts, i.e., can be clamped and fixed by the two clamping parts. In addition, the integrated cage can be adsorbed by the adsorption assembly during hoisting, so as to avoid random shaking of the integrated cage and assist the integrated cage to be placed stably and accurately at the target position. The integrated cage fixing device provided by the embodiments of the present application can prevent the cage from shaking randomly, and the integrated cage can be fixed by controlling the two clamping parts to move on the rotating screw by controlling the lifting of the lifting assembly. Compared with the welding method of the cage to the ship body in the prior art, the convenience of the integrated cage fixing operation is improved, and the cage is not cut, so the structural strength of the cage is not damaged, and the structural safety and reliability of the cage during use are ensured.
