In order to ensure the stability of the equipment, it is necessary to use anchoring or dropping anchors to anchor the waterborne equipment to prevent large displacement or swaying.

[0003] Anchoring of waterborne equipment is done by dropping anchors, which takes a long time. Anchor piles take up a lot of space, and raising anchors requires auxiliary equipment, making the operation inconvenient. Summary of the Invention

The anchor piles can be spliced ​​together and can adaptively change the anchoring / lifting speed according to the load. This reduces the overall height of the water equipment while making full use of the prime mover power and saving operation time.

Detailed Implementation

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] This embodiment provides a reversible anchoring device that can switch the anchor pile from a horizontal to a vertical position. The anchor piles can be spliced ​​together, and the anchoring / lifting speed can be adaptively changed according to the load. This reduces the overall height of the waterborne equipment while making full use of the prime mover power and saving operation time.

[0029] like Figure 1 As shown, the anchoring device includes: a chain adjustment mechanism 1, a chain 2, a splicable anchor pile 3, a guide pile frame 5, and a hydraulic cylinder 6; wherein, as Figure 2 As shown, the chain adjustment mechanism 1 includes: a pin I 1.1, a pull rod 1.2, and a nut 1.3; Figure 3 As shown, the guide pile frame 5 includes: roller 5.1, driven sprocket I 5.2, reducer 5.3, driving sprocket 5.4, driven sprocket II 5.5, connecting lug 5.6 and pile cylinder 5.7;

[0030] Both ends of the chain 2 are installed on both ends of the splicable anchor pile 3 via chain adjustment mechanisms 1. Each chain adjustment mechanism 1 has a pull rod 1.2 with an external thread at one end, which passes through the mounting hole at the top of the splicable anchor pile 3 and is fixed to the splicable anchor pile 3 by a nut 1.3. The other end is a double-ear seat with ear holes, into which a pin I 1.1 is inserted. The pin I 1.1 serves as the rotation shaft at the end of the chain 2, allowing the chain 2 to be rotatably connected to the pull rod 1.2. This enables the chain 2 to be connected to the splicable anchor pile 3 via the chain adjustment mechanism 1. The upper end of the splicable anchor pile 3 has a groove extending along its length to accommodate the chain 2. By rotating the nut 1.3, the pull rod 1.2 can be extended and retracted relative to the splicable anchor pile 3 and moved left and right, thereby adjusting the tension of the chain 2.

[0031] The guide pile frame 5 is fitted outside the modular anchor pile 3 and is used to guide the modular anchor pile 3 and connect it to the deck of the surface equipment. Specifically, the pile cylinder 5.7 has a square hole inside to facilitate the insertion of the modular anchor pile 3. When the modular anchor pile 3 is in a horizontal state, rollers 5.1 are installed on the upper and lower sides of the left end of the pile cylinder 5.7 through mounting lugs. The rims of the two rollers 5.1 on opposite sides extend into the square hole inside the pile cylinder 5.7 and cooperate with the square hole inside the pile cylinder 5.7 to guide the modular anchor pile 3. Connecting lugs 5.6 are installed on the upper and lower sides of the right end of the pile cylinder 5.7. The lower connecting lug 5.6 rotates with a lug seat on the surface equipment deck through pin III. The connection is as follows: the upper connecting lug 5.6 is a spare; on the upper side of the pile cylinder 5.7 between the roller 5.1 and the connecting lug 5.6, from left to right, driven sprocket I 5.2, reducer 5.3 and driven sprocket II 5.5 are installed sequentially through the mounting lugs; on the lower side of the pile cylinder 5.7 between the roller 5.1 and the connecting lug 5.6, there is a cylinder mounting lug; the piston rod end lug of the hydraulic cylinder 6 is rotatably connected to the cylinder mounting lug through pin IV; the cylinder end is rotatably connected to another lug on the deck of the water equipment through pin V; the extension and retraction of the hydraulic cylinder 6 drives the guide pile frame 5 to switch between horizontal and vertical positions; the driving sprocket 5.4 is installed on the housing of the reducer 5.3;

[0032] The middle section of chain 2 passes sequentially around driven sprocket I 5.2, driving sprocket 5.4, and driven sprocket II 5.5, and meshes with them. Simultaneously, a hydraulic motor is mounted on reducer 5.3 to drive its operation, which in turn drives driving sprocket 5.4 to drive chain 2. This chain 2 then causes the connectable anchor pile 3 to rotate, enabling its lowering or raising. When the connectable anchor pile 3 is in a vertical position, the hydraulic motor can drive it to move up and down, achieving anchoring and raising of the equipment. Driven sprockets I 5.2 and II 5.5 guide and tighten the chain 2, preventing tooth skipping.

[0033] In this embodiment, as Figure 4 As shown, the splicable anchor pile 3 includes: an upper pile 3.1, a connecting joint 3.2, and a lower pile 3.3; both the upper pile 3.1 and the lower pile 3.3 are concave box girders, and the openings of the two concave box girders face upwards, forming a groove for accommodating the chain 2; one end of the lower pile 3.3 is a pile tip, and the other end is a concave connecting port, with a pin hole I left at the concave connecting port; one end of the connecting joint 3.2 is welded to the upper pile 3.1, and the other end has a pin hole II; after the connecting joint 3.2 is inserted into the concave connecting port of the lower pile 3.3, the connecting pin 4 is passed through the pin hole I and the pin hole II to realize the splicing of the splicable anchor pile 3.

[0034] In this embodiment, as Figure 5As shown, the connecting pin 4 includes: pin shaft II 4.1, locking block 4.2, spring 4.3, and bolt 4.4; the pin shaft II 4.1 has a stepped hole in the radial direction in the middle of its axial direction, and locking block 4.2 and bolt 4.4 are respectively provided at both ends, with the smaller end being a smooth hole and the larger end being a threaded hole; the locking block 4.2 is a cylindrical shape with a shoulder, and its shoulder can abut against the step of the stepped hole; the two ends of the spring 4.3 abut against the locking block 4.2 and bolt 4.4 respectively, and when the spring 4.3 extends, it can press the locking block 4.2 tightly against the step of the stepped hole; when the connecting pin 4 is inserted into the connecting joint 3.2, the locking block 4.2 pops out under the action of the spring 4.3 and is locked into the radially reserved groove in the middle of the pin hole II of the connecting joint 3.2, so as to realize the stable connection of the splicable anchor pile 3.

[0035] In this embodiment, the end of the card block 4.2 facing the card slot is machined into a spherical or ellipsoidal shape to facilitate quick insertion into the card slot.

[0036] In this embodiment, the hydraulic motor is a two-point automatic variable displacement motor, which can automatically adjust the motor to a large displacement and a small displacement according to different loads, thereby automatically adjusting the speed of the hydraulic motor. When lowering the anchor, the corresponding hydraulic system outputs a large flow of low-pressure oil to achieve rapid anchor lowering and prevent the equipment on the water from moving with the water flow. When raising the anchor, the corresponding hydraulic system outputs a small flow of high-pressure oil to output a large pulling force and achieve smooth anchor raising.

[0037] In this embodiment, a hydraulic pump provides high-pressure oil to the hydraulic system and delivers it to the hydraulic cylinder 6 and the hydraulic motor through connecting pipelines. The hydraulic pump is a constant power variable pump, which can set the maximum system power according to the power of the prime mover to make full use of the prime mover power.

[0038] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
