Description

Technical Field

[0001] This utility model relates to a tension bracket for a novel anchor chain tensioner, belonging to the field of anchor chain tensioning technology. Background Technology

[0002] The foundation of an offshore floating wind turbine is anchored to the seabed through a mooring system. When the anchor chain of the mooring system is installed, the tension of the anchor chain under mooring force needs to be tightened to the designed preload state through an anchor chain tensioner.

[0003] During the tensioning process of the anchor chain, it is necessary to ensure the chain-stopping effect of the anchor chain retraction. See Chinese patent application publication number CN110316318A. When two solid support arms 11 are used to form the installation base of the chain-stopping arm, the chain-stopping arm is located between two spaced support arms 11, making it inconvenient to visually observe the locking and contact state between the chain-stopping arm and the anchor chain from the side. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a new type of anchor chain tensioner tension bracket.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a novel tension bracket for an anchor chain tensioner, comprising: Tension brace; Two solid support arms are fixedly connected to one end of the tension bracket, and the two support arms are spaced apart. The two spaced-apart support arms are equipped with observation windows.

[0007] The other end of the tension bracket is provided with an anchor chain bolt for connecting the anchor cylinder and anchor chain.

[0008] There is a support space between the two spaced support arms. Within the support space between the support arms, there is an anchor chain that needs to be pulled and tensioned, and a short chain stop tongue that engages and locks the anchor chain. The observation window is set on the support arm corresponding to the positions of the anchor chain and the short chain stop tongue.

[0009] An arc-shaped plate is fixedly connected to the tension bracket near the anchor chain bolt.

[0010] The support arm, located away from the anchor chain bolt, is rotatably mounted with a five-jaw sprocket.

[0011] The five-jaw sprocket consists of two spaced-apart sprocket discs, which are fixedly connected by a sprocket connecting shaft.

[0012] Each of the sprocket discs has a sprocket claw integrally fixedly connected to its radial outer circumferential surface. There are five sprocket claws distributed circumferentially. There is a sprocket gap between the sprocket claws on the two sprocket discs. The width of the sprocket gap is greater than that of the anchor chain protrusion but smaller than that of the anchor chain flat section. The radial surface of the sprocket disc is provided with a chain groove to accommodate the anchor chain flat section.

[0013] The support arm is rotatably mounted with a chain stopper body via a chain stop pin.

[0014] The top of the chain stopper body is fixedly connected to a short chain stop tongue for engaging and locking the anchor chain and a long chain stop tongue for installing the elastic element. The short chain stop tongue and the long chain stop tongue are forked.

[0015] The beneficial effects of this utility model are as follows: the through hole facilitates observation of the engagement between the chain stop tongue and the anchor chain, and allows for timely adjustment of the elasticity of the elastic element. This solves the problem that when the chain stop arm is between two solid support arms, it is inconvenient to visually observe the locking and engagement state between the chain stop arm and the anchor chain from the side.

Detailed Implementation

[0017] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0018] See Figures 1 to 8 As shown.

[0019] This application discloses a novel anchor chain tensioner, comprising: A tension bracket 1 for connecting the anchor chain on the anchor tube is provided. Two spaced support arms 11 are integrally fixedly connected to the tension bracket 1. An anchor chain bolt hole 14 is provided at the end of the tension bracket 1 away from the support arm 11. The anchor chain bolt hole 14 is used to connect the anchor chain on the anchor tube.

[0020] An arc-shaped plate 17 is integrally fixedly connected to the tension bracket 1 near the anchor chain bolt 14. The arc-shaped plate 17 is integrally fixedly connected to the tension bracket 1 via the chain stop release arm 16. The arc-shaped plate 17 provides sliding support for the anchor chain 4.

[0021] The arc-shaped plate 17 facing the support arm 11 has a circular arc surface, and the arc-shaped plate 17 contacts the anchor chain 4 through the circular arc surface.

[0022] A five-jaw sprocket 2 is rotatably mounted on the support arm 11, away from the anchor chain bolt opening 14. The five-jaw sprocket 2 provides rolling support for the anchor chain 4. There is a gap between the arc plate 17 and the five-jaw sprocket 2 for the anchor chain 4 to be pulled.

[0023] The arc plate 17 provides sliding support for the anchor chain 4, and the five-jaw sprocket 2 provides rolling support for the anchor chain 4, allowing the anchor chain 4 to be tensioned selectively under sliding or rolling guidance support. When the anchor chain 4 needs to be pulled quickly for tension, the anchor chain 4 is provided with rolling support through the rotatable five-jaw sprocket 2, and the anchor chain 4 is pulled on the rotatable five-jaw sprocket 2, thereby reducing excessive sliding contact of the anchor chain 4.

[0024] A rotatable sprocket according to this application includes: a five-jaw sprocket 2 rotatably mounted on a support arm 11.

[0025] The five-jaw sprocket 2 is composed of two spaced sprocket discs 21, which are fixedly connected as a whole by a sprocket connecting shaft 24.

[0026] The sprocket disc 21 located at the sprocket connecting shaft 24 is provided with a concave structural groove 23, so that the end of the sprocket connecting shaft 24 protrudes into the structural groove 23; the sprocket connecting shaft 24 can be rotatably installed with the sprocket rotating hole 12 at the top of the support arm 11 through the sprocket pin 191.

[0027] Each of the sprocket discs 21 has a sprocket claw 22 integrally fixedly connected to its radial outer circumference. There are five sprocket claws 22 distributed circumferentially. There is a sprocket gap 27 between the sprocket claws 22 on the two sprocket discs 21. The width of the sprocket gap 27 is greater than the protruding joint of the anchor chain 4 but smaller than the flat joint of the anchor chain 4. This ensures that the sprocket gap 27 can only accommodate the protruding joint of the anchor chain 4, and the flat joint of the anchor chain 4 cannot enter the sprocket gap 27.

[0028] The radial surface of the sprocket disc 21 is provided with a chain groove 28 for accommodating the flat section of the anchor chain 4.

[0029] The sprocket claws 22 of the two sprocket discs 21 can abut against the protruding section of the anchor chain 4. The flat section of the anchor chain 4 is accommodated in the chain groove 28, so that each section of the anchor chain 4 can drive the five-claw sprocket 2 to rotate once when it passes through, ensuring that the five-claw sprocket 2 provides rotational guidance and stability for the anchor chain 4.

[0030] The sprocket disc 21 has through circular holes 26, which are five in a circumferential array. The circular holes 26 reduce the weight of the sprocket disc 21. There is a sprocket claw 22 between every two circular holes 26, thereby reducing the rotational inertia of the sprocket claw 22.

[0031] The present application discloses a novel anchor chain tensioner with a rotatable chain stop device, comprising: a chain stop body 3 having a chain stop shaft hole 32, wherein the chain stop shaft hole 32 on the chain stop body 3 is rotatably hinged to the chain stop rotating hole 13 at the bottom of the support arm 11 via a chain stop pin 192.

[0032] The bottom of the chain stopper body 3 is integrally fixed with a chain stopper weight 31, the weight of which is greater than the sum of the weights of the chain stopper long tongue 34 and the chain stopper short tongue 33. The top of the chain stopper body 3 is integrally fixed with a chain stopper short tongue 33 that abuts against the locking anchor chain 4 and a chain stopper long tongue 34 for installing the elastic element 5. The chain stopper long tongue 34 and the chain stopper short tongue 33 are forked. The chain stopper weight 31 pulls the chain stopper body 3 around the chain stopper pin 192 by its own downward gravity, so that the chain stopper short tongue 33 abuts against the locking anchor chain 4 in normal condition.

[0033] The chain stop tongue 34 has a through-type construction groove 37 in the middle, which is used to reduce the weight of the chain stop tongue 34.

[0034] The end of the chain stop tongue 34, which is away from the chain stopper body 3, is provided with a manually operated drag chain buckle hole 35 and a spring hook hole 36 distributed at intervals. The manually operated drag chain buckle hole 35 allows a finger to be inserted to pull the chain stop tongue 34, causing the chain stopper body 3 to rotate around the chain pin 192. The spring hook hole 36 is wrapped and fixedly installed with an elastic element 5. The elastic element 5 is fixedly connected to the anchor chain bolt 14. The middle part of the elastic element 5 is distributed on the tension bracket 1 at the root of the chain stopper release arm 16, so that the middle part of the elastic element 5 is in contact support.

[0035] When the anchor chain 4 rolls around the five-jaw sprocket 2 to tighten, the anchor chain 4 presses against the chain stop tongue 33 and rotates counterclockwise. At this time, the elastic element 5 is pulled into an elastic state. The elastic force of the elastic element 5 pulls the chain stop tongue 34, causing the chain stop body 3 to rotate clockwise around the chain pin 192, so that the chain stop tongue 33 always abuts and locks the anchor chain 4 in its normal state. When the anchor chain 4 falls back, it will be locked by the chain stop tongue 33, so that the anchor chain 4 can only be pulled upwards to tighten.

[0036] After the elastic element 5 experiences fatigue and a decrease in elasticity, the amount by which the elastic element 5, which is composed of elastic rubber body, is wound and fixed on the spring hook hole 36 can be adjusted to facilitate the adjustment of the elasticity of the elastic element 5.

[0037] This application discloses a novel anchor chain tensioner with a tension bracket, comprising: A tension bracket 1 with an anchor chain bolt 14 at one end is provided, and the anchor chain bolt 14 is used to connect the anchor chain on the anchor tube. The other end of the tension bracket 1 is integrally fixedly connected to two spaced bracket arms 11; there is a bracket space 18 between the two spaced bracket arms 11, and there is an anchor chain 4 that needs to be pulled and tensioned and a stop chain tongue 33 that abuts and locks the anchor chain 4 within the bracket space 18 between the bracket arms 11.

[0038] Two spaced-apart support arms 11 are provided with observation windows 15. The observation windows 15 are observation holes that pass through the support arms 11. The observation windows 15 are set on the support arms 11 at the positions corresponding to the anchor chain 4 and the chain stop tongue 33.

[0039] The through hole 15 facilitates observation of the engagement between the chain stop tongue 33 and the anchor chain 4, allowing for timely adjustment of the elasticity of the elastic element 5. This addresses the problem that when the chain stop arm is positioned between two solid support arms 11, it is inconvenient to visually observe the locking and engagement state of the chain stop arm and the anchor chain from the side.
