At the same time, the swinging of the anchor cable poses a safety hazard.
The anti-wear launching and recovering device adopts a winch, guide rollers and sliding rollers. The guide rollers guide the cable and a basic support frame and sliding rollers are set at the hatch to change sliding friction into rolling friction, reduce friction loss, and control the swing of the anchor cable through a spring buffer structure.
It effectively reduces anchor cable friction loss, protects the ship's structure, lowers maintenance costs, improves construction safety and efficiency, and avoids safety hazards to operators caused by anchor cable swaying.

TECHNICAL FIELD
[0001] The utility model relates to a positioning anchor, especially an anchor cable anti-abrasion winding and unwinding device. BACKGROUND
[0002] In the process of offshore wind power foundation pile construction, the construction ship must ensure accurate positioning to complete the piling task, so the construction ship needs to throw the positioning anchor. At present, in the process of winding and unwinding the positioning anchor, the following main problems exist:
[0003] Firstly, when the construction ship winds and unwinds the positioning anchor, the anchor cable directly passes through the hatch and will slide and rub against the cabin wall, causing serious abrasion of the anchor cable, thereby shortening the service life of the anchor cable, increasing the frequency of replacing the anchor cable, and increasing the construction cost and the burden of ship maintenance. At the same time, the friction can also damage the cabin wall surface, causing damage to the ship structure.
[0004] Secondly, when the anchor cable is subjected to tension, the anchor cable will swing up and down and left and right, bringing certain safety hazards to the nearby operators. Especially in the offshore construction environment, the weather conditions are uncertain, and when the wind and waves are large, the swinging amplitude of the anchor cable can be more severe, increasing the probability and severity of accidents. SUMMARY
[0005] The technical problem to be solved by the utility model is to provide an anchor cable anti-abrasion winding and unwinding device, which can reduce the friction loss of the anchor cable and the swinging amplitude of the anchor cable.
[0006] To solve the above technical problems, the utility model adopts the following technical scheme:
[0007] An anchor cable anti-abrasion winding and unwinding device, comprising a winch arranged inside a cabin wall, a positioning anchor cable being led out through the winch, the positioning anchor cable passing through a hatch of the cabin wall and being guided by a guide roller; a base support frame is fixed at the hatch, and a sliding roller is mounted around the inner edge of the base support frame.
[0008] Each sliding roller is connected with a sliding block at both ends, the sliding block is slidingly arranged in a sliding groove and is tightly pressed by a compression spring on one side, and the sliding groove is mounted on the base support frame.
[0009] The sliding roller is coated with a rubber ring.
[0010] The sliding roller comprises a central shaft, and the central shaft is rotatably connected with an outer sleeve at both ends through bearings.
[0011] Flanges are arranged at both ends of the central shaft, and the flanges are connected with the sliding block.
[0012] The sliding roller is made of stainless steel and is coated with a corrosion-resistant coating on the surface.
[0013] The size of the base support frame is less than the size of the hatch.
[0014] The anchor cable anti-abrasion winding and unwinding device has the following technical effects:
[0015] 1) By combining the base support frame with the sliding roller, the sliding friction between the anchor cable and the cabin wall in the traditional construction operation is changed into rolling friction when the positioning anchor is wound and unwound in the offshore wind power foundation pile construction process, the friction loss of the anchor cable is reduced, the ship structure is protected, and the construction and maintenance cost is reduced.
[0016] 2) The sliding roller is arranged around the base support frame, the position and direction of the anchor cable can be controlled, and the safety hazards brought to the operator by the up-down and left-right swing of the anchor cable in the positioning anchor construction operation process are avoided.
[0017] 3) By setting the two ends of the sliding roller as a structure with spring buffering, the sliding roller has a certain buffering property when the positioning anchor cable swings due to strong wind, and the deformation caused by long-term impact of the anchor cable is reduced.

[0025] As Figures 1-2As shown, an anchor cable anti-wear winding and unwinding device includes a winch 1 arranged in a cabin, a guide roller 2 arranged outside the cabin and guiding the positioning anchor cable 5, the positioning anchor cable 5 winding on the winch 1 after passing through the hatch 4 of the cabin wall 3 after passing through the guide roller 2. A base support frame 7 is arranged at the hatch 4, which limits the anchor cable within a fixed and movable space range, so that the operator does not need to worry about the damage caused by the swing of the anchor cable during the construction operation, and the construction efficiency and safety are significantly improved.
[0026] The hatch is originally a rectangle with a size of 2.2*1.5 meters, and the device is a rectangle with a size of 1m*0.8m, which effectively limits the swing range of the anchor cable wire rope.
[0027] Meanwhile, sliding rollers 8 are arranged in the upper, lower, left and right directions of the base support frame 7, which guide the positioning anchor cable 5 entering the cabin and optimize the sliding friction of the positioning anchor cable 5 with the cabin wall 3 to rolling friction, which can greatly reduce the friction loss of the anchor cable. At the same time, since the sliding rollers 8 are arranged around, the direct contact between the cabin wall 3 and the positioning anchor cable 5 is avoided, so that the ship structure is prevented from being damaged.
[0028] As shown in Figures 3-4 Preferably, the sliding roller 8 includes a center shaft 8.1, both ends of the center shaft 8.1 are rotatably connected with an outer sleeve 8.3 through bearings 8.2, so that the outer sleeve 8.3 can be rotated when the positioning anchor cable 5 moves. Flanges 9 are arranged at both ends of the center shaft 8.1, the flanges 9 are connected with sliding blocks 10, the sliding blocks 10 are slidingly arranged in sliding grooves 11 and are tightly pressed on the inner end faces of the sliding grooves 11 away from the base support frame 7 through compression springs 12. By arranging the compression springs 12, the sliding roller 8 can be buffered when the positioning anchor cable 5 swings greatly in strong wind and waves, so that the sliding roller 8 is prevented from being deformed by being hit.
[0029] As shown in Figure 5 The sliding roller 8 is covered with a rubber ring 8.4. The rubber ring 8.4 plays an isolation role, which can prevent the sliding roller 8 from being eroded by seawater accumulated on the positioning anchor cable 5, and also can further prevent wear.
