Description

Technical Field

[0001] This utility model relates to the field of tension device technology, and in particular to an assembly tension device. Background Technology

[0002] Ship components refer to the various structural parts and equipment components that make up the hull, engine room, deck, outfitting, etc., including steel plates, profiles, welded parts, pipes, valves, bolts, etc. They collectively bear the ship's strength, rigidity, waterproofing, and functional requirements. In order to perform stress calibration and pre-tightening on these components during ship construction and maintenance, it is necessary to install tensioning devices to ensure that the fastening force of the connection meets the design requirements, preventing structural deformation, leakage, or failure caused by loose bolts or stress concentration in welds, thereby improving overall safety and service life.

[0003] In the current ship component assembly process, the commonly used tensioning devices mostly adopt simple turnbuckles and chain hoists, which have many shortcomings: the traditional turnbuckle has a fixed connection at both ends, making it difficult to adapt to the docking of components at different angles and positions under complex working conditions; although chain hoists can provide greater tension, they are bulky, cumbersome to operate, require additional hoisting support, and cannot achieve fine adjustment and self-locking. Therefore, we propose an assembly tensioning device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an assembly tension device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tension assembly includes a steel wire rope, with hooks fixedly connected to the outer walls of both ends of the steel wire rope. A U-shaped rod is fitted inside each hook. A first fixing plate and a connecting plate are fixedly connected to one end of each U-shaped rod, respectively. A threaded rod is fixedly connected to the outer wall of the connecting plate. A circular sleeve is threadedly fitted onto the outer wall of the threaded rod. A turntable is fixedly connected to one end of the circular sleeve. A T-shaped ring is fixedly connected to the outer wall of the turntable. A tension sleeve is rotatably fitted onto the outer wall of the circular sleeve. Multiple levers are fixedly connected to the outer wall of the turntable. An anti-rotation component is provided on the outer wall of the tension sleeve. An ear plate is fixedly connected to one end of the tension sleeve. Two foot plates are rotatably connected to the outer wall of the ear plate. A second fixing plate is fixedly connected to one end of each foot plate.

[0007] Preferably, the anti-rotation component includes a metal ring, wherein the outer wall of one of the handles is slidably connected to the inner wall of the metal ring, and a rope is fixedly connected to the outer wall of the metal ring. One end of the rope is fixedly connected to the outer wall of the tension sleeve. The anti-rotation component fundamentally prevents the turntable from accidentally rotating after tensioning, which could lead to tension failure and avoid safety hazards.

[0008] Preferably, the outer wall of the tension sleeve is provided with an annular groove, the inner wall of the annular groove is rotatably connected to the outer wall of the T-shaped ring, and the annular groove and the annular groove of the tension sleeve form a rotatable fit structure to ensure that the tension sleeve always remains stationary when the turntable and the sleeve rotate freely.

[0009] Preferably, one end of the threaded rod is located inside the tension sleeve, and the internal space of the tension sleeve provides an area for the threaded rod to move.

[0010] Preferably, the outer walls of both foot plates and ear plates are provided with through holes, and the inner walls of the through holes are rotatably connected to I-shaped shafts. The two foot plates and ear plates can be adjusted at multiple angles by rotating around the I-shaped shafts.

[0011] Preferably, the outer walls of the first fixing plate and the second fixing plate are evenly provided with a plurality of foot holes.

[0012] Compared with the prior art, the advantages of this utility model are:

[0019] 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.

[0020] Depend on Figures 1-3 As shown, an assembly tensioning device is involved, including a steel wire rope 1. The steel wire rope 1 has high strength and tensile strength characteristics, which can stably transmit the axial tension of the threaded rod 6 to the first fixed plate 4 to achieve tensioning of the two structural components. Its flexible material can adapt to the connection requirements of different angles and avoid the stress limitations of traditional rigid connections under complex working conditions.

[0021] Hooks 2 are fixedly connected to the outer walls of both ends of the wire rope 1. U-shaped rods 3 are sleeved inside the two hooks 2. The two hooks 2 achieve quick connection between the wire rope 1, the first fixing plate 4, and the connecting plate 5 by sleeved U-shaped rods 3. No complicated installation tools are required, and disassembly and docking can be completed quickly, improving operation efficiency. Furthermore, the hooks 2 cannot be rotated on the U-shaped rods 3.

[0022] One end of each of the two U-shaped rods 3 is fixedly connected to a first fixing plate 4 and a connecting plate 5. The connecting plate 5 can smoothly transmit the tension from the wire rope 1 to the threaded rod 6. The threaded rod 6, through thread engagement with the round sleeve 7, converts the rotational motion of the round sleeve 7 into its own axial linear motion, thereby generating tension. At the same time, it supports the axial tension of the threaded rod 6 in the opposite direction, achieving balanced force transmission.

[0023] A threaded rod 6 is fixedly connected to the outer wall of the connecting plate 5. A circular sleeve 7 is threadedly fitted onto the outer wall of the threaded rod 6. A turntable 10 is fixedly connected to one end of the circular sleeve 7. The rotation direction of the turntable 10 is the same as the twist direction of the wire rope 1. A T-shaped ring 8 is fixedly connected to the outer wall of the turntable 10. A tension sleeve 9 is rotatably fitted onto the outer wall of the circular sleeve 7. An annular groove is formed on the outer wall of the tension sleeve 9. The inner wall of the annular groove is rotatably connected to the outer wall of the T-shaped ring 8. The annular groove and the annular groove of the tension sleeve 9 form a rotatable fit structure to ensure that the tension sleeve 9 remains stationary when the turntable 10 and the circular sleeve 7 rotate freely. One end of the threaded rod 6 is located inside the tension sleeve 9. The internal space of the tension sleeve 9 provides an active area for the threaded rod 6.

[0024] Multiple levers 11 are fixedly connected to the outer wall of the turntable 10. The levers 11 are used to increase the operating lever arm and reduce labor intensity, so that a single person can complete the tension adjustment operation.

[0025] One end of the tension sleeve 9 is fixedly connected to an ear plate 14. The outer wall of the ear plate 14 is rotatably connected to two foot plates 15. One end of the two foot plates 15 is fixedly connected to the same second fixing plate 16. The outer walls of the two foot plates 15 and the ear plate 14 are provided with through holes. The inner wall of the through holes is rotatably connected to an I-shaped shaft 17. The two foot plates 15 and the ear plate 14 can rotate around the I-shaped shaft 17 to realize the multi-angle adjustment of the second fixing plate 16, which can adapt to the docking of components at different angles under complex working conditions. The outer walls of the first fixing plate 4 and the second fixing plate 16 are evenly provided with multiple foot holes.

[0026] The outer wall of the tension sleeve 9 is provided with an anti-rotation component, which includes a metal ring 12. The outer wall of one of the levers 11 is slidably connected to the inner wall of the metal ring 12. A rope 13 is fixedly connected to the outer wall of the metal ring 12. One end of the rope 13 is fixedly connected to the outer wall of the tension sleeve 9. The metal ring 12 and the rope 13 connect and fix the turntable 10 to the tension sleeve 9, fundamentally preventing the turntable 10 from accidentally rotating after tensioning, which would cause the tension to fail and avoid safety hazards.

[0027] Working principle: When using this assembly tension device, the operator first holds and rotates the multiple levers 11 on the turntable 10, which drives the fixed sleeve 7 to rotate. Since the sleeve 7 is threadedly connected to the threaded rod 6 and the threaded rod 6 is fixed to the connecting plate 5, the first fixing plate 4 and the second fixing plate 16 are moved away from each other.

[0028] Then, the hooks 2 at both ends of the wire rope 1 are respectively fitted onto the U-shaped rods 3 on the first fixing plate 4 and the connecting plate 5 to form an initial connection;

[0029] Then, the first fixing plate 4 and the second fixing plate 16 are fixed to the two structural components that need to be tightened or connected through multiple foot holes on their outer walls (in conjunction with existing bolts and nuts);

[0030] When tension needs to be applied, the operator holds and rotates the multiple levers 11 on the turntable 10, causing the circular sleeve 7 fixed thereto to rotate. Since the circular sleeve 7 is threadedly connected to the threaded rod 6, and the threaded rod 6 is fixed to the connecting plate 5, the rotating circular sleeve 7 causes the threaded rod 6 to move axially away from the first fixed plate 4. The tension sleeve 9 is rotatably connected to the T-shaped ring 8 fixed on the turntable 10 through its internal annular groove, ensuring that the turntable 10 and the circular sleeve 7 can rotate freely while the tension sleeve 9 does not rotate with them.

[0031] The linear motion of the threaded rod 6 is ultimately transmitted to the first fixed plate 4 through the wire rope 1, achieving tension between the two structural components. To prevent the turntable 10 from rotating unexpectedly after tensioning, the metal ring 12 can be slid along one of the handles 11 and locked, while the rope 13 connected to it is tied to the tension sleeve 9 as a safety measure, thereby completing the application and locking of the tension.

[0032] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
