Description

Technical Field

[0001] The present application relates to the technical field of hoisting, and in particular to a hoisting device. Background Art

[0002] In the marine membrane containment system, LNG (liquefied natural gas) marine storage tanks need to ensure good insulation effects and have a certain degree of pressure resistance. For this reason, when the tank is manufactured, a protective layer needs to be laid on the inner wall of the tank to improve the storage safety of LNG in the tank.

[0003] Reference Figure 1 The bottom wall and side wall of the storage tank need to be covered with a protective layer 9, the outermost side of the protective layer 9 is a shielding plate 91, the surface of the shielding plate 91 is crisscrossed horizontally and vertically, and a knot 92 is formed at the intersection. For large storage tanks, the protective layer 9 on the side wall of the storage tank needs to be built layer by layer, and the plate on the side wall needs to be hoisted by a hoisting device. The hoisting device is built on the bottom wall of the storage tank, and the plate is hoisted to a certain height by the hoisting device, so as to form a protective layer 9 on the side wall of the storage tank.

[0004] If the bottom wall of the storage tank is not covered with a protective layer, the lifting equipment can be directly built on the bottom wall of the storage tank to lift the plate. However, in practice, in order to improve the laying effect of the protective layer of the storage tank, according to the design requirements, it is often necessary to first build the protective layer from the bottom wall of the storage tank, and then build the protective layer from the side wall of the storage tank to ensure a good connection between the protective layer of the bottom wall and the protective layer of the side wall. In this case, once the protective layer of the bottom wall of the storage tank is built, it is difficult to avoid the need to penetrate the protective layer of the bottom wall of the storage tank with bolts when connecting the lifting equipment to the bottom wall of the storage tank, which will inevitably cause structural damage to the protective layer of the bottom wall of the storage tank, thereby reducing the storage safety of LNG in the storage tank. Therefore, there is an urgent need for a lifting equipment that can adapt to the completed protective layer of the bottom wall of the storage tank to reduce the structural damage to the protective layer of the bottom wall of the storage tank when the lifting equipment is built. Summary of the invention

[0005] In order to reduce the structural damage to the protective layer of the bottom wall of the tank when the lifting equipment is erected, the present application provides a lifting equipment.

[0006] The present application provides a lifting device that adopts the following technical solution: A lifting device comprises a movable track and a lifting body, wherein the movable track is arranged on a protective layer on the bottom wall of a storage tank, and the lifting body is slidably installed on the movable track for lifting a plate; a plurality of connecting seats are arranged at the bottom of the movable track, and the connecting seats are installed at the knot of a shielding plate; a fixed clamp and a movable clamp are respectively arranged on the bottom wall of the connecting seat, and a clamping area for the knot of the shielding plate to be embedded is formed between the fixed clamp and the movable clamp; the movable clamp is slidably installed on the bottom wall of the connecting seat so as to be able to approach or move away from the fixed clamp; and the connecting seat is provided with a driving component for driving the movable clamp to slide.

[0007] By adopting the above technical solution, when the lifting equipment is built, the connection seat is placed at the knot of the shielding plate, and then the driving component drives the movable clamp to move toward one side of the fixed clamp, reducing the size of the clamping area, so that the fixed clamp and the movable clamp are clamped together on the knot of the shielding plate, so that the connection seat is installed on the protective layer of the bottom wall of the tank; then a moving track for the sliding of the lifting body is laid on the connection seat, so that the lifting body can lift the plate, reducing the structural damage to the protective layer of the bottom wall of the tank when the lifting equipment is built. After the protective layer of the side wall of the tank is built, the lifting body and the moving track are disassembled in turn, and then the movable clamp is driven to move toward the side away from the fixed clamp, so that the connection seat can be disassembled, thereby improving the convenience of disassembly and assembly of the overall structure.

[0008] Optionally, the knot of the shielding plate includes cross-arranged transverse ribs and longitudinal ribs, and when the movable clamp moves toward the side close to the fixed clamp, the fixed clamp and the movable clamp are respectively clamped on both sides of the transverse ribs; the bottom wall of the fixed clamp and the bottom wall of the movable clamp are both provided with positioning arc grooves, and the positioning arc grooves are used for matching and embedding of the longitudinal ribs.

[0009] By adopting the above technical solution, when installing the connecting seat, the fixed clamp and the movable clamp are aligned with the longitudinal reinforcement and lowered, so that the longitudinal reinforcement is embedded in the positioning arc groove of the fixed clamp and the positioning arc groove of the movable clamp, respectively matching the embedded positioning arc groove of the fixed clamp, and the positioning arc groove plays the effect of locating the orientation of the connecting seat, thereby improving the installation accuracy of the connecting seat; after the fixed clamp and the movable clamp are positioned by their respective positioning arc grooves, the movable clamp is driven to move toward one side of the fixed clamp, so that the fixed clamp and the movable clamp can be clamped on both sides of the transverse reinforcement respectively, thereby improving the installation convenience and installation accuracy of the connecting seat.

[0010] Optionally, two opposite side walls of the fixed clamp and the movable clamp are provided with positioning protrusions, and two opposite sides of the transverse ribs are provided with positioning grooves for the positioning protrusions to match and embed.

[0011] By adopting the above-mentioned technical solution, the fixed clamp and the movable clamp are aligned with the longitudinal reinforcement and lowered, so that the longitudinal reinforcement is embedded in the positioning arc groove of the fixed clamp and the positioning arc groove of the movable clamp, and then the movable clamp is driven to move toward one side of the fixed clamp, so that the fixed clamp and the movable clamp can be clamped on both sides of the transverse reinforcement respectively. During this process, the positioning protrusion of the fixed clamp and the positioning protrusion of the movable clamp can be respectively embedded in the positioning grooves on the opposite sides of the transverse reinforcement, so as to further limit the connecting seat, reduce the possibility of the connecting seat rotating freely around the longitudinal reinforcement and causing the surface of the connecting seat to tilt, and improve the connection stability between the connecting seat and the knot.

[0012] Optionally, a sliding plate is slidably installed on the bottom wall of the connecting seat, the movable clamp is arranged on the side wall of the sliding plate close to the fixed clamp, and the movable clamp is slidably installed on the connecting seat through the sliding plate; the driving assembly includes a push rod, a force handle and a swing bar, the push rod is slidably installed on the bottom of the connecting seat and is located on the side of the sliding plate away from the fixed clamp; one end of the force handle is hinged to the bottom of the connecting seat, the force handle is respectively connected to a first connecting column and a second connecting column, one end of the swing bar is hinged to the push rod, and the other end is hinged to the first connecting column, when the force handle is driven to rotate and the second connecting column abuts against the swing bar, the push rod drives the movable clamp to abut against the knot of the shielding plate through the sliding plate.

[0013] By adopting the above technical solution, after the connecting seat is placed at the knot of the shielding plate, the force handle is rotated, and the force handle pushes the push rod through the swing bar, thereby driving the sliding plate to move toward the side close to the fixed clamp, so that the fixed clamp and the movable frame are clamped together on the knot of the shielding plate. In this state, the second connecting column abuts against the swing bar to keep the push rod always in a tight state; when disassembling, the force handle is pulled in the opposite direction to evacuate the push rod, thereby improving the convenience of disassembly and assembly of the connecting seat.

[0014] Optionally, the side walls of the sliding plate away from the fixing clamp are respectively provided with a straight push block and a side push block, and two side push blocks are provided and symmetrically distributed on both sides of the straight push block; a pushing assembly is provided between the straight push block and the side push block, and when the push rod moves toward the side close to the fixing clamp, the pushing assembly forces the straight push block and the side push block to synchronously push the sliding plate toward one side of the fixing clamp.

[0015] By adopting the above technical solution, after the connecting seat is placed at the flower knot, the push rod is driven to move toward the side close to the fixed frame. Under the action of the pushing assembly, the straight push block and the two side push blocks can simultaneously push the sliding plate toward one side of the fixed frame, so that the sliding plate slides to force the fixed clamp and the movable clamp to clamp the flower knot together; the setting of the straight push block and the two side push blocks can disperse the pushing force of the push rod, so that the force at each position of the sliding plate is more uniform, thereby improving the pushing effect on the movable clamp, and then improving the clamping effect on the flower knot.

[0016] Optionally, two opposite side walls of the straight push block are provided with oblique push grooves, the two oblique push grooves are arranged correspondingly to the two side push blocks, and one side of each of the oblique push grooves passes through the side wall of the straight push block away from the sliding plate; the pushing assembly includes two oblique push rods, the two oblique push rods are arranged correspondingly to the two side push blocks, one end of each of the oblique push rods is connected to the corresponding side push block, and the other end passes through the corresponding oblique push groove and extends to the side of the straight push block away from the sliding plate for the push rod to abut; the inner wall of the oblique push groove has a first oblique push surface for the oblique push rod to abut.

[0017] By adopting the above technical scheme, the push rod is driven to move toward the side close to the fixed frame, and the push rod pushes the two oblique push rods at the same time. The oblique push rods are subjected to force acting on the corresponding side push blocks, forcing the two side push blocks to be subjected to a component force moving away from each other and a component force used to push the sliding plate, so that both sides of the sliding plate are subjected to the same thrust. At the same time, in the process of the push rod pushing the two oblique push rods, the oblique push rod pushes the first oblique push surface of the oblique push groove, and the straight push block is subjected to force to form a thrust on the sliding plate, thereby improving the uniformity of force on the sliding plate, thereby ensuring that the sliding plate slides along a straight line, and improving the clamping effect of the movable clamp and the fixed clamp on the knot.

[0018] Optionally, each of the side push blocks has a second inclined push surface on its side wall close to the straight push block, one end of the inclined push rod is connected to the second inclined push surface, and the second inclined push surface of the side push block is vertically arranged to the first inclined push surface of the corresponding inclined push groove.

[0019] By adopting the above technical solution, the push rod pushes the oblique push rod, and the thrust received by the oblique push rod acts on the second oblique push surface, thereby dividing the thrust into two components (the two side push blocks are subjected to a component force moving away from each other and a component force used to push the sliding plate) to disperse the thrust of the push rod and improve the force uniformity of the sliding plate.

[0020] Optionally, the movable track is provided with a first connecting hole, the connecting seat is provided with a through groove, the straight push block is slidably installed on the sliding plate, and the second connecting hole is provided in the middle position of the top wall of the straight push block; the movable track is installed with a connecting bolt, and the connecting bolt passes through the first connecting hole, the through groove and the second connecting hole in sequence and is threadedly connected to the second connecting hole; the first inclined push surface is gradually inclined from bottom to top toward the side close to the second connecting hole.

[0021] By adopting the above technical scheme, the top push rod pushes the inclined push rod, driving the sliding plate to move toward one side of the fixed clamp, so that the fixed clamp and the movable clamp are clamped on the knot together. At this time, the movable rail is laid on the connecting seat, and then the connecting bolts are sequentially passed through the first connecting hole, the passing groove and the second connecting hole, and the connecting bolts are threadedly connected to the second connecting hole. After the connecting bolts are locked, an upward pulling force is exerted on the straight push block, so that the first inclined push surface can squeeze the inclined push rod. Since one end of the inclined push rod is connected to the side push rod and the other end abuts the top push rod, that is, the inclined push rod remains stationary in this state, the first inclined push surface forms a reaction force against the extrusion of the inclined push rod, so as to drive the straight push block to tighten the sliding plate, thereby improving the connection stability between the connecting seat and the knot.

[0022] Optionally, two movable rails are arranged side by side, a reinforcing rod is provided between the two movable rails, and the two movable rails are connected in series with each other through the reinforcing rod; a docking rod is provided on the connecting seat of the movable rail, a docking assembly is provided between the docking rod and the reinforcing rod, and the reinforcing rod can be detachably mounted on the docking rod of the connecting seat through the docking assembly.

[0023] By adopting the above technical solution, the connecting seats of the two movable rails are connected in series through the reinforcing rod, so as to improve the installation stability of the overall structure; after the protective layer of the side wall of the tank is built, the reinforcing rod is disassembled through the docking assembly.

[0024] Optionally, the docking assembly includes a docking sleeve, a limit sleeve, a first spring, a second spring and a limit ball, the docking sleeve is slidably installed on the outer peripheral wall of the docking rod, and the first spring is installed between the docking sleeve and the docking rod; the outer peripheral wall of the docking sleeve is provided with a limit hole, the limit sleeve is slidably sleeved on the outer peripheral wall of the docking sleeve, the second spring is installed between the limit sleeve and the docking sleeve, and the second spring forces the limit sleeve to cover the limit hole; the limit ball is embedded in the limit hole, and the outer peripheral wall of one end of the reinforcing rod is provided with a limit ring groove for the limit ball to be embedded, when the limit sleeve covers the limit hole, the inner wall of the limit sleeve pushes the limit ball and forces the limit ball to be partially embedded in the limit ring groove.

[0025] By adopting the above technical scheme, the reinforcing rod is placed between the connecting seats of the two moving rails, so that the two ends of the reinforcing rod are aligned with the docking rods of the connecting seats of the two moving rails, and then the docking sleeve is pulled to force the docking sleeve to move toward one side of the reinforcing rod. When the limiting hole is moved to be opposite to the limiting ring groove of the reinforcing rod, the limiting sleeve is moved toward the side away from the connecting seat under the action of the second spring to cover the limiting hole. In this process, the inner wall of the limiting sleeve pushes the limiting ball, forcing the limiting ball to be partially embedded in the limiting ring groove to achieve the connection between the docking rod and the reinforcing rod; when disassembling, the limiting sleeve is pulled to force the limiting hole to be exposed, and the docking sleeve can be moved toward the side away from the reinforcing rod under the action of the first spring, so that the docking sleeve is separated from the reinforcing rod, which greatly improves the convenience of disassembly and assembly between the docking rod and the reinforcing rod.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the setting of the connection seat and the driving component, when the lifting equipment is built, the connection seat is placed at the knot of the shielding plate, and then the driving component is used to drive the movable clamp to move toward one side of the fixed clamp, thereby reducing the size of the clamping area, so that the fixed clamp and the movable clamp are clamped together on the knot of the shielding plate, so that the connection seat is installed on the protective layer of the bottom wall of the tank; then a movable track is laid on the connection seat for the sliding of the lifting body, so that the lifting body can lift the plate and reduce the structural damage to the protective layer of the bottom wall of the tank when the lifting equipment is built. After the protective layer of the side wall of the tank is built, the lifting body and the movable track are removed in turn, and then the movable clamp is driven to move toward the side away from the fixed clamp to remove the connection seat, thereby improving the convenience of disassembly and assembly of the overall structure; 2. Through the arrangement of the straight push block and the side push block, after the connection seat is placed at the knot, the push rod is driven to move toward the side close to the fixed frame. Under the action of the pushing assembly, the straight push block and the two side push blocks can simultaneously push the sliding plate toward one side of the fixed frame, so that the sliding plate slides to force the fixed clamp and the movable clamp to clamp the knot together; the arrangement of the straight push block and the two side push blocks can disperse the pushing force of the push rod, so that the force at each position of the sliding plate is more uniform, thereby improving the pushing effect on the movable clamp and thus improving the clamping effect on the knot; 3. Through the setting of the docking assembly, the reinforcing rod is placed between the connecting seats of the two moving rails, so that the two ends of the reinforcing rod are aligned with the docking rods of the connecting seats of the two moving rails, and then the docking sleeve is pulled to force the docking sleeve to move toward one side of the reinforcing rod. When the limiting hole is moved to be opposite to the limiting ring groove of the reinforcing rod, the limiting sleeve is moved toward the side away from the connecting seat under the action of the second spring to cover the limiting hole. In this process, the inner wall of the limiting sleeve pushes the limiting ball, forcing the limiting ball to be partially embedded in the limiting ring groove to achieve the connection between the docking rod and the reinforcing rod; when disassembling, the limiting sleeve is pulled to force the limiting hole to be exposed, and the docking sleeve can be moved toward the side away from the reinforcing rod under the action of the first spring, so that the docking sleeve is separated from the reinforcing rod, which greatly improves the convenience of disassembly and assembly between the docking rod and the reinforcing rod.

[0048] Reference Fig. 9 In this embodiment, the first inclined push surface 352 is gradually inclined from bottom to top toward a side close to the second connecting hole 353.

[0049] The implementation principle of Example 3 of the present application is as follows: the top push rod 41 pushes the inclined push rod 5, driving the sliding plate 34 to move toward one side of the fixed clamp 31, so that the fixed clamp 31 and the movable clamp 32 are clamped together on the knot 92. At this time, the movable rail 1 is laid on the connecting seat 3, and then the connecting bolt 12 is sequentially passed through the first connecting hole 11, the passing groove 37 and the second connecting hole 353, and the connecting bolt 12 is threadedly connected with the second connecting hole 353. After the connecting bolt 12 is locked, an upward pulling force is exerted on the straight push block 35, so that the first inclined push surface 352 can squeeze the inclined push rod 5. Since one end of the inclined push rod 5 is connected to the side push rod and the other end abuts the top push rod 41, that is, the inclined push rod 5 remains stationary in this state, and the first inclined push surface 352 forms a reaction force on the squeezing of the inclined push rod 5, so as to drive the straight push block 35 to press the sliding plate 34, thereby improving the connection stability between the connecting seat 3 and the knot 92.

[0050] Embodiment 4:

[0051] The embodiment of the present application discloses a hoisting device.

[0052] The difference between the lifting equipment disclosed in the embodiment of the present application and the embodiment 1 is that: Reference Fig.10 , Fig.11 In this embodiment, a reinforcing rod 6 is installed between the two moving rails 1, and a docking rod 7 for docking the reinforcing rod 6 is fixedly installed on the side wall of the connecting seat 3 of the moving rail 1. The connecting seats 3 of the two moving rails 1 are connected in series with each other through the reinforcing rod 6; a docking assembly 8 is provided between the docking rod 7 and the reinforcing rod 6, and the reinforcing rod 6 can be detachably installed on the docking rod 7 of the connecting seat 3 through the docking assembly 8.

[0053] The docking assembly 8 includes a docking sleeve 81, a limiting sleeve 82, a first spring 83, a second spring 84 and a limiting ball 85. The docking sleeve 81 is slidably installed on the outer peripheral wall of the docking rod 7. The first spring 83 is sleeved on the outer peripheral wall of the docking rod 7. One end of the first spring 83 is fixedly connected to the docking rod 7, and the other end is fixedly connected to the docking sleeve 81. Under normal circumstances, the first spring 83 forces the docking sleeve 81 to move toward one side of the connecting seat 3 so that the docking rod 7 is away from the end surface of the connecting seat 3 and exposed to the docking sleeve 81; a plurality of limiting holes 811 are opened on the outer peripheral wall of the end of the docking sleeve 81 away from the connecting seat 3, and the plurality of limiting holes 811 are arranged at intervals around the central axis of the docking sleeve 81, and each limiting hole 811 passes through the inner peripheral wall of the docking sleeve 81.

[0054] The limiting sleeve 82 is slidably sleeved on the outer peripheral wall of the docking sleeve 81, and the second spring 84 is sleeved on the outer peripheral wall of the docking sleeve 81. One end of the second spring 84 is fixedly connected to the docking sleeve 81, and the other end is fixedly connected to the limiting sleeve 82. Under normal circumstances, the second spring 84 forces the limiting sleeve 82 to move toward the side away from the connecting seat 3 so that the limiting sleeve 82 covers all the limiting holes 811; there are multiple limiting balls 85, and the multiple limiting balls 85 are correspondingly arranged with the multiple limiting holes 811, and each limiting ball 85 is embedded in the corresponding limiting hole 811; a limiting ring groove 61 is provided on the outer peripheral wall of one end of the reinforcing rod 6, and the limiting ring groove 61 is arranged in a ring shape around the central axis of the reinforcing rod 6 for the limiting ball 85 to be embedded; when the limiting sleeve 82 covers the limiting hole 811, the inner wall of the limiting sleeve 82 pushes the limiting ball 85 and forces all the limiting balls 85 to be partially embedded in the limiting ring groove 61.

[0055] It should be noted that a positioning ring 62 is fixedly installed on the outer peripheral wall of the reinforcing rod 6. When the docking sleeve 81 is driven to abut against the positioning ring 62, the limiting hole 811 is opposite to the limiting ring groove 61; a first force rod 812 for driving the docking sleeve 81 to slide is fixedly installed on the outer peripheral wall of the docking sleeve 81, and a second force rod 821 for driving the limiting sleeve 82 to slide is fixedly installed on the outer peripheral wall of the limiting sleeve 82; limiting convex rings are installed at the openings at both ends of the limiting hole 811, and the inner diameter of the limiting convex ring is smaller than the outer diameter of the limiting ball 85 to reduce the possibility of the limiting ball 85 falling out of the limiting hole 811 completely.

[0056] The implementation principle of Example 4 of the present application is as follows: when installing the reinforcing rod 6, place the reinforcing rod 6 between the connecting seats 3 of the two moving rails 1, so that the two ends of the reinforcing rod 6 are aligned with the docking rods 7 of the connecting seats 3 of the two moving rails 1, and then hold the first force rod 812 and the second force rod 821 at the same time to pull the docking sleeve 81 toward the side away from the connecting seat 3. When the docking sleeve 81 abuts against the positioning ring 62 (that is, the limiting hole 811 is opposite to the limiting ring groove 61), release the second force rod 821, and the limiting sleeve 82 moves toward the side away from the connecting seat 3 under the action of the second spring 84 to push the limiting ball 85, forcing the limiting ball 85 to embed into the limiting ring groove 61, thereby realizing the connection between the docking rod 7 and the reinforcing rod 6.

[0057] During disassembly, the second force-applying rod 821 is used to force the limiting sleeve 82 to slide toward the side close to the connecting seat 3, so that the limiting sleeve 82 is separated from the limiting hole 811. At this time, the docking sleeve 81 is displaced toward the side close to the connecting seat 3 under the action of the first spring 83, so that the docking sleeve 81 is separated from the reinforcing rod 6, which greatly improves the convenience of disassembly and assembly between the docking rod 7 and the reinforcing rod 6; the reinforcing rod 6 connects the connecting seats 3 of the two movable rails 1 in series, thereby improving the installation stability of the overall structure.

[0058] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
