Description

Technical Field

[0001] The utility model relates to an adaptive hull curved surface supporting device, belonging to the technical field of shipbuilding. Background Art

[0002] Ship block docking technology is a commonly used manufacturing method in the ship production and manufacturing process. During the docking process of the block and the sub-block, the technology of lifting and moving the ship section through the jacking moving device is becoming more and more mature and the frequency of application is increasing.

[0003] The bottom of the ship section is mostly a non-planar structure, and the connection with the side is a curved surface transition. Therefore, during the jacking work of the ship body, the contact stability between the jacking trolley and the bottom of the ship section is a problem that must be solved during the ship section docking process. At present, during the jacking process of the ship section, the positioning of the lifting structure and the surface of the ship section is achieved by measuring the matching position of the jacking trolley and the ship section in advance, moving the jacking trolley to the specified position, and then starting the jacking mechanism until it contacts the surface of the ship section. The connection structure between the jacking mechanism and the ship section adopts suction cups, special lifting structures that match the shape of the ship section, etc. When these connection structures are in contact with the ship section during jacking, since the lifting cylinder of the jacking trolley is rigid and the position of the jacking trolley is fixed, if there is a positioning deviation, the connection structure matching the ship section will be mismatched, resulting in the inability to provide safe and effective jacking.

[0004] Therefore, in order to solve the impact of the position error of the connecting structure during the jacking process, there is an urgent need for a connecting structure that can overcome the influence of the error and achieve stable jacking. Summary of the Invention

[0005] Purpose of the invention: In view of the deficiencies in the prior art, the present invention provides an adaptive hull curved surface support device to solve the problems mentioned in the above background technology.

[0006] Technical solution: An adaptive hull curved surface support device includes support units mounted in a rectangular array on a transport trolley, each support unit including a lifting cylinder fixedly connected to the transport trolley and an adaptive support assembly provided at the lifting end of the lifting cylinder;

[0007] The adaptive support assembly includes a chassis fixedly connected to the outer side of the lifting end of the lifting cylinder and a top plate with an electromagnetic suction cup on the upper end. The top plate and the chassis are connected by a parallel mechanism arranged between the chassis and the top plate. The top plate is hinged to the lifting end of the lifting cylinder through a support and a ball bearing.

[0008] The utility model provides a parallel mechanism and a ball bearing structure. When the top plate contacts the surface of the ship section, the ball bearing can make the overall direction of the adaptive support component roughly the same as the direction of the ship section surface. At this time, the electromagnetic suction cup is energized with a small current to generate a small adsorption force between the electromagnetic suction cup and the surface of the ship section, thereby correcting the corresponding positions of the top plate and the ship section. When the lifting cylinder continues to lift, if the lifting position deviates, the electromagnetic suction cup will slide on the surface of the ship section through the squeezing of the lifting cylinder until the sliding stops, which means that the force at this position is balanced. At this time, the current intensity is increased to make the electromagnetic suction cup generate maximum adsorption force, and the parallel mechanism is locked to achieve positioning, thereby providing a basis for subsequent safe lifting and transportation.

[0009] The electromagnetic chuck includes at least three electromagnetic chuck units distributed in a circular array on the top plate. One side of any electromagnetic chuck unit close to the middle of the top plate is hinged to the upper end of the top plate, and the other side abuts against the upper end of the top plate, so that the electromagnetic chuck unit can rotate upward.

[0010] In order to adapt to the curved surface of the ship section and ensure that the electromagnetic suction cup can fit the curved surface and provide stable support, the electromagnetic suction cup is decomposed into at least three electromagnetic suction cup monomers, and the monomers are hingedly connected to the top plate. Under low current conditions, the electromagnetic suction cup monomers can rotate on their own to adsorb to the ship section, and then continue to lift, correct the adsorption position, increase the current intensity, so that the electromagnetic suction cup monomers can be stably adsorbed on the hull surface. When targeting the curved hull, the three electromagnetic suction cup monomers form a stable support surface. At the same time, during the transportation of the ship section, when starting and braking, the force generated by the inertia of the ship section, because the electromagnetic suction cup monomers are distributed in a circular array, their hinged positions have constraints at various angles in the horizontal direction, so they can be effectively constrained in the starting and braking stages to prevent the problem of position changes caused by inertia of the hull during movement.

[0011] Electromagnetic bosses are evenly distributed at equal intervals on the upper end of the electromagnetic chuck, and the electromagnetic bosses cover the entire upper end surface of the electromagnetic chuck.

[0012] The surface of the ship section is adsorbed by evenly distributed electromagnetic bosses, which increases the strength of the electromagnetic suction cup and provides better support. After wear and tear caused by long-term work, only the electromagnetic bosses need to be replaced accordingly, without the need to replace the entire structure, thus reducing maintenance costs.

[0013] The parallel mechanism includes at least three groups of adjusting cylinders corresponding to the number and position of the electromagnetic suction cup units, and any group of adjusting cylinders includes at least one adjusting cylinder unit whose two ends are hinged to the edges of the top plate and the bottom plate respectively, and the outer diameter of the top plate is smaller than the outer diameter of the bottom plate.

[0014] The parallel mechanism is set as an adjusting cylinder, which can use the hydraulic system of the lifting cylinder itself to provide oil for it, and through hydraulic braking positioning, it can provide a more stable and safe supporting force. The outer diameters of the top plate and the chassis are different, so the adjusting cylinder can be installed at an angle. When supporting a flat surface, the pillars and the lifting cylinder bear the vertical downward force. When supporting a curved surface, the force is transmitted to the pillars and the lifting cylinder through the adjusting cylinder to achieve stable support.

[0015] The connection between the bottom of the top plate and the regulating oil cylinder is arranged as an inclined support surface which is inclined downward from the edge of the top plate toward the support column.

[0016] The setting of the inclined support surface makes the retracted side closer to the vertical state when the adjusting cylinder deflects to one side, and the force is transmitted in the vertical downward direction as much as possible, making the support more stable.

[0017] The middle part of the top plate is a circular hollow structure, the top of the pillar is provided with a step surface, and the top of the pillar is provided with at least two spaced-apart mounting parts, the outer side of the mounting part is an arc surface that is interference fit with the inner side surface of the middle part of the top plate, and the bottom of the top plate abuts against the step surface of the top of the pillar.

[0018] The top plate and the pillars are made into a separate structure, and two mounting parts are set on the top of the pillars for interference fit with the top plate, so that the top plate only needs to be snapped in during installation. The integrated design has high cost and maintenance cost.

[0019] Beneficial effect: The utility model sets a parallel mechanism and a ball bearing structure. When the top plate contacts the surface of the ship section, the ball bearing can make the overall direction of the adaptive support component roughly the same as the direction of the ship section surface. At this time, the electromagnetic suction cup is energized and a small current is used to generate a smaller adsorption force between the electromagnetic suction cup and the surface of the ship section, thereby correcting the corresponding positions of the top plate and the ship section. When the lifting cylinder continues to lift, if the lifting position deviates, the electromagnetic suction cup will slide on the surface of the ship section through the squeezing of the lifting cylinder until the sliding stops, which means that the force at this position is balanced. At this time, the current intensity is increased to make the electromagnetic suction cup generate maximum adsorption force, and the parallel mechanism is locked to achieve positioning, providing a basis for subsequent safe lifting and transportation.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0027] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0028] like Figures 1 to 3 As shown, an adaptive hull curved surface support device includes support units mounted in a rectangular array on a transport trolley, each support unit includes a lifting cylinder 1 fixedly connected to the transport trolley and an adaptive support assembly provided at the lifting end of the lifting cylinder 1;

[0029] The adaptive support assembly includes a chassis 2 fixedly connected to the outer side of the lifting end of the lifting cylinder 1 and a top plate 3 with an electromagnetic suction cup 4 on the upper end. The top plate 3 and the chassis 2 are connected by a parallel mechanism arranged between the chassis 2 and the top plate 3. The top plate 3 is hinged to the lifting end of the lifting cylinder 1 through a support 5 and a ball bearing 6.

[0030] The utility model provides a parallel mechanism and a ball bearing 6 structure. When the top plate 3 contacts the surface of the ship section, the ball bearing 6 can make the overall direction of the adaptive support assembly roughly the same as the direction of the ship section surface. The parallel mechanism causes the top plate 3 to move when the bottom plate 2 does not move. At this time, the electromagnetic suction cup 4 is energized with a small current to generate a small adsorption force between the electromagnetic suction cup 4 and the surface of the ship section, thereby correcting the corresponding positions of the top plate 3 and the ship section. When the lifting cylinder 1 continues to lift, if the lifting position deviates, the electromagnetic suction cup 4 will slide on the surface of the ship section through the squeezing of the lifting cylinder until the sliding stops, which means that the force at this position is balanced. At this time, the current intensity is increased to make the electromagnetic suction cup 4 generate the maximum adsorption force, and the parallel mechanism is locked to achieve positioning, thereby providing a basis for subsequent safe lifting and transportation.

[0031] The electromagnetic chuck 4 includes at least three electromagnetic chuck units 41 distributed in a circular array on the top plate 3. One side of any electromagnetic chuck unit 41 near the middle of the top plate 3 is hinged to the upper end of the top plate 3 in a movable manner, and the other side abuts against the upper end of the top plate 3, so that the electromagnetic chuck unit 41 can rotate upward.

[0032] In order to adapt to the curved surface of the ship section and ensure that the electromagnetic suction cup 4 can fit the curved surface and provide stable support, the electromagnetic suction cup 4 is decomposed into at least three electromagnetic suction cup monomers 41, and the monomers are hingedly connected to the top plate 3. Under low current conditions, the electromagnetic suction cup monomer 41 can rotate on its own to adsorb to the ship section, and then continue to lift, correct the adsorption position, increase the current intensity, so that the electromagnetic suction cup monomer 41 can be stably adsorbed on the surface of the hull. When targeting a curved hull, the three electromagnetic suction cup monomers 41 form a stable support surface. At the same time, during the transportation of the ship section, when starting and braking, the force generated by the inertia of the ship section, since the electromagnetic suction cup monomers 41 are distributed in a circular array, their hinged positions have constraints at various angles in the horizontal direction, so they can be effectively constrained in the starting and braking stages to prevent the problem of position changes caused by inertia of the hull during movement.

[0033] Electromagnetic bosses 42 are evenly distributed at equal intervals on the upper end of the electromagnetic chuck 4 , and the electromagnetic bosses 42 cover the entire upper end surface of the electromagnetic chuck 4 .

[0034] The surface of the ship section is adsorbed by the evenly distributed electromagnetic bosses 42, which increases the strength of the electromagnetic suction cup 4 and provides better support. After wear and tear occurs during long-term operation, only the electromagnetic bosses 42 need to be replaced accordingly, without the need to replace the entire structure, thus reducing maintenance costs.

[0035] The parallel mechanism includes at least three groups of adjusting cylinders 7 corresponding to the number and position of the electromagnetic suction cup units 41. Any group of adjusting cylinders 7 includes at least one adjusting cylinder unit 71 whose two ends are hinged to the edges of the top plate 3 and the bottom plate 2 respectively, and the outer diameter of the top plate 3 is smaller than the outer diameter of the bottom plate 2.

[0036] The parallel mechanism is set as an adjusting cylinder 7, which can use the hydraulic system of the lifting cylinder 1 itself to provide oil for it, and through hydraulic braking positioning, it can provide a more stable and safe supporting force. The outer diameters of the top plate 3 and the chassis 2 are different, so the adjusting cylinder 7 can be installed at an angle. When supporting a flat surface, the pillar 5 and the lifting cylinder 1 bear the vertical downward force. When supporting a curved surface, the force is transmitted to the pillar 5 and the lifting cylinder 1 through the adjusting cylinder 7 to achieve stable support.

[0037] like Figure 4 As shown, the connection between the bottom of the top plate 3 and the regulating cylinder 7 is set as an inclined support surface 31 inclined downward from the edge of the top plate 3 toward the support 5.

[0038] The setting of the inclined support surface 31 enables the regulating cylinder 7 to shift to one side, and the contracted side is closer to a vertical state, so that the force is transmitted in the vertical downward direction as much as possible, making the support more stable.

[0039] The middle part of the top plate 3 is a circular hollow structure, the top of the pillar 5 is provided with a stepped surface, and the top of the pillar 5 is provided with at least two spaced-apart mounting portions 51, the outer side of the mounting portion 51 is an arc surface that is interference fit with the inner side surface of the middle part of the top plate 3, and the bottom of the top plate 3 abuts against the stepped surface on the top of the pillar 5.

[0040] The top plate 3 and the pillar 5 are made into a separate structure, and two mounting parts 51 for interference fit with the top plate 3 are set on the top of the pillar 5, so that the top plate 3 only needs to be snapped in when installed. The integrated design has high cost and maintenance cost.

Reference can be made to the common and similar parts between the various embodiments. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the method description.
