AI Technical Summary
On offshore wind power lifting platform, due to the influence of sea breeze during non-operating conditions, temporary reinforcement of cable-stay is required, but because there is only one eyepiece with a wound hole space, it is impossible to wind and install the two cable-stays simultaneously.
A temporary fixing eye plate for marine activity equipment is designed, including a spacing-distributed side eye plate and a middle eye plate. There is a spacing between the middle eye plates to form multiple winding hole spaces. Two zig-stays can be simultaneously wound on the anti-pin shafts on both sides of the middle eye plate.
By increasing the winding hole space, the problem that the eye plate with only one winding hole space cannot be wound in two traps simultaneously, and the synchronous winding installation of two traps on the offshore wind power lifting platform is achieved.

Abstract
Description
Technical Field
[0001] The utility model relates to an eyebolt for temporarily fixing marine movable equipment, belonging to the technical field of fixing connecting pieces. Background Technique
[0002] For movable equipment such as crawler cranes on an offshore wind power hoisting platform, during non-operation conditions, due to the influence of sea breeze, it is necessary to carry out inclined cable temporary reinforcement.
[0003] When carrying out inclined cable temporary reinforcement, sometimes more than two inclined cables are required for inclined pulling, as shown in Chinese Patent Publication No. CN113915478B. When winding and pulling with a winding inclined cable such as a rope or a steel chain, when there is only an eyebolt with one winding hole space, it will cause the problem that the two inclined cables cannot be wound and installed synchronously. Content of the Utility Model
[0004] To solve the above technical problems, the utility model provides an eyebolt for temporarily fixing marine movable equipment.
[0005] The utility model is achieved through the following technical solutions.
[0006] An eyebolt for temporarily fixing marine movable equipment provided by the utility model includes:
[0007] Side eyebolts and an intermediate eyebolt, both of which are provided with pin holes for inserting anti-loosening pins.
[0008] There are two spaced-apart side eyebolts; the intermediate eyebolt is located between the spaced-apart side eyebolts. The pin holes of the side eyebolts and the pin holes of the intermediate eyebolt are coaxially inserted with anti-loosening pins.
[0009] An inclined cable is wound around the anti-loosening pin.
[0010] It further includes a mounting base plate that is fixed on the deck of the offshore wind power hoisting platform during use. Two spaced-apart side eyebolts are fixed on the mounting base plate, and an intermediate eyebolt is fixed on the mounting base plate between the two side eyebolts.
[0011] There are multiple intermediate eyebolts, and there are intervals between the intermediate eyebolts.
[0012] The beneficial effect of the utility model is that two inclined cables form two winding hole spaces between the corresponding intermediate eyebolts and the two side eyebolts, and the two inclined cables are synchronously wound around the anti-loosening pins on both sides of the intermediate eyebolt, solving the problem that when there is only an eyebolt with one winding hole space, the two inclined cables cannot be wound and installed synchronously.

[0021] The technical solution of the present utility model will be further described below, but the scope of protection claimed is not limited thereto.
[0022] As Figures 1 to 7 shown.
[0023] An eyebolt for temporarily fixing a marine activity equipment in the present application includes:
[0024] A mounting base plate 1 fixed on the deck of a marine wind power hoisting platform during use. A side eyebolt 21 is fixed on the mounting base plate 1, and there are two spaced - apart side eyebolts 21. A middle eyebolt 22 is fixed on the mounting base plate 1 between the two side eyebolts 21. When there are multiple middle eyebolts 22, there are intervals between the middle eyebolts 22. Pin shaft holes 3 are provided on the middle eyebolt 22 and the side eyebolts 21 for inserting the anti - detachment pin shaft 7. Two winding hole spaces for two stay cables 5 to pass through and wind are formed between the middle eyebolt 22 and the two side eyebolts 21. When there are multiple middle eyebolts 22, the winding hole spaces increase accordingly.
[0025] Two stay cables 5 form two winding hole spaces corresponding to the middle eyebolt 22 and the two side eyebolts 21, and the two stay cables 5 are wound synchronously on the anti - detachment pin shafts 7 on both sides of the middle eyebolt 22, solving the problem that when there is only one winding hole space in the eyebolt, the two stay cables cannot be wound and installed synchronously.
[0026] When conducting inclined cable temporary reinforcement, a winding inclined cable member such as a rope or a steel chain is wound around the pin shaft of the eye plate. In a sea breeze environment, it is necessary to ensure that the pin shaft has anti-disengagement properties. For the existing pin shaft technology for anti-disengagement, see Chinese Patent Publication No. CN208951065U. Although the first stop block can achieve anti-disengagement through bolts, there is a problem that the anti-disengagement member cannot be adjusted to adapt to the actual connection situation, resulting in poor practicability.
[0027] An anti-disengagement pin shaft 7 of the present application includes:
[0028] A pin shaft rod 73 as the main structure, one end of the pin shaft rod 73 is integrally and fixedly connected with an anti-disengagement plate 71. The anti-disengagement plate 71 is larger than the pin shaft rod 73. There is a rope-sheathing groove 72 between the anti-disengagement plate 71 and the pin shaft rod 73. The inclined cable 5 composed of a rope or a steel chain can be initially wound in the rope-sheathing groove 72.
[0029] A threaded hole 74 is provided in the middle of the pin shaft rod 73, and the threaded hole 74 is used for screwing with a long screw rod 77.
[0030] At the other end of the pin shaft rod 73, a cross groove 76 is provided. A cross-shaped anti-disengagement cross 78 can be slidably installed in the cross groove 76. The anti-disengagement cross 78 is larger than the pin shaft rod 73. The anti-disengagement cross 78 and the anti-disengagement plate 71 prevent the two ends of the pin shaft rod 73 from disengaging. A cylindrical cavity 75 is provided on the pin shaft rod 73, and the cylindrical cavity 75 is used to accommodate the connecting cylinder 79 in the middle of the anti-disengagement cross 78; the cylindrical cavity 75 is larger than the threaded hole 74. The anti-disengagement cross 78 is installed on the other end of the pin shaft rod 73 by screwing the long screw rod 77 with the threaded hole 74, and the anti-disengagement cross 78 is adjusted axially on the pin shaft rod 73 by the long screw rod 77 to adapt to eye plates of different widths.
[0031] When the winding width of the inclined cable 5 composed of a rope or a steel chain increases or the number of strands increases, the middle eye plate 22 of the eye plate correspondingly increases, causing the width of the eye plate to increase. At this time, the long screw rod 77 is screwed out axially from the pin shaft rod 73 to adapt. This solves the problem that the anti-disengagement member cannot be adjusted to adapt to the actual connection situation, resulting in poor practicability. At this time, the anti-disengagement cross 78 and the anti-disengagement plate 71 abut against the two side eye plates 21 to achieve anti-disengagement, so that the anti-disengagement pin shaft 7 is located in the eye hole 23, and the inclined cable 5 is synchronously wound around the anti-disengagement pin shafts 7 on both sides of the middle eye plate 22.
