Description

Technical Field

[0001] The utility model relates to the technical field of cable guide rollers, in particular to a cable guide roller for ships with a self-protection function. Background Art

[0002] The cable roller of a ship is an important component of the ship's mooring device. When the ship is berthing at a dock or mooring a buoy, the cable roller guides the nylon rope or wire rope mooring cable through its rotation to tie the ship to the dock or buoy. Publication (Announcement) No.: CN220054071U discloses a ship cable roller, including a mounting seat, a guide member arranged on the top of the mounting seat, the guide member includes a connecting shaft fixedly connected to the top of the mounting seat, a roller body rotatably connected to the outside of the connecting shaft through a bearing, and a rubber sleeve sleeved on the outside of the roller body, a plurality of countersunk holes are evenly arranged on the rubber sleeve along the circumferential direction, and the countersunk holes penetrate the rubber sleeve along the radial direction of the rubber sleeve, and threaded holes corresponding to the countersunk holes are opened on the outer wall of the roller body, and each countersunk hole is provided with a connecting bolt, the head of the connecting bolt is tightly pressed against the inner wall of the countersunk hole, and the threaded section of the connecting bolt is threadedly connected to the threaded hole. A rubber sleeve is arranged on the outside of the roller body to increase the friction between the ship guide cable and the guide roller. In this way, during the process of pulling the ship guide cable, the ship guide cable can drive the roller body to rotate, making it difficult for relative sliding to occur between the ship guide cable and the roller body, thereby reducing the wear of the ship guide cable.

[0003] The above-mentioned prior art solutions have the following defects: since the cable guide roller is used on a ship and the guide is in an open use environment, the ship is sailing in the sea, and the cable guide roller is in a severe high-salt and high-humidity environment for a long time, and it is easy to be corroded; at the same time, more seawater easily invades between the connecting shaft and the roller body, causing it to be corroded. The cable guide roller is easy to get stuck on the rope when rotating, and it cannot work normally, reducing the stability of use and service life. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a ship cable guide roller with a self-protection function, which reduces the erosion of seawater on the surface of the V-shaped roller and the supporting shaft, and improves the stability and service life of use.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a ship cable guide roller with a self-protection function, comprising: a U-shaped mounting seat and a V-shaped roller arranged in the inner cavity thereof, a support shaft is passed through the center of the V-shaped roller, and both ends of the support shaft are passed through the U-shaped mounting seat and are rotatably connected thereto;

[0006] The outer side of the V-shaped roller is sleeved with an inner arc-shaped protective cover assembly, the outer side of the inner arc-shaped protective cover assembly is sleeved with an outer arc-shaped protective cover assembly, and the support shaft is penetrated through the inner arc-shaped protective cover assembly and the outer arc-shaped protective cover assembly and is rotatably connected thereto;

[0007] The outer arc-shaped protective cover assembly comprises an outer arc-shaped cover body and an introduction hole arranged on the outer circumferential surface thereof;

[0008] The inner arc-shaped protective cover assembly comprises an inner arc-shaped cover body and a guide hole arranged on the outer surface thereof, and the inner arc-shaped cover body and the outer arc-shaped cover body are staggered and overlapped in the circumferential direction.

[0009] By adopting the above technical scheme, when in use, one end of the cable is inserted into the lead-in hole on the outer arc protective cover assembly, the cable is wound around the V-shaped groove of the V-shaped roller and then extends out from the lead-out hole of the inner arc protective cover assembly. Since the support shaft is rotatably connected to the inner arc protective cover assembly and the outer arc protective cover assembly respectively, the inner arc protective cover assembly and the outer arc protective cover assembly can be properly adjusted in the circumferential direction according to the moving path of the cable, and the inner arc cover body and the outer arc cover body are staggered and overlapped in the circumferential direction. The inner arc cover body and the outer arc cover body have a wrapping and protective effect on the V-shaped roller, which reduces the erosion of the V-shaped roller and the support shaft by seawater, reduces the probability of rust of the V-shaped roller and the support shaft, and extends the service life.

[0010] In a preferred example, the utility model can be further configured as follows: the inner arc cover body includes an inner arc plate and a fan-shaped plate connected to the inner walls at both ends thereof, the inner hole of the fan-shaped plate is connected to an annular seat, the annular seat is rotatably connected to the outer circle of the support shaft, and the outer circle surface of the inner arc plate is provided with the guide hole.

[0011] By adopting the above technical solution, the inner arc plate and the fan-shaped plate 1 have the function of preventing seawater from corroding the V-shaped roller and the support shaft. Since the annular seat 1 is rotatably connected to the support shaft, the inner arc cover body can rotate in a circle along the support shaft.

[0012] In a preferred example, the utility model can be further configured as follows: two first guide roller assemblies are spaced apart and connected to the outer circular surface of the inner arc plate, the guide holes are provided between the first guide roller assemblies, the minimum gap between the first guide roller assemblies is smaller than the inner diameter of the guide holes, the first guide roller assembly includes a first guide roller body and a support seat rotatably connected at both ends thereof, and the end of the support seat away from the first guide roller body is connected to the end of the inner arc cover body.

[0013] By adopting the above technical solution, when the cable passes through the lead-out hole, the cable is respectively connected to the first guide roller body in a rolling manner, which reduces the probability of large friction between the cable and the lead-out hole and prolongs the service life of the cable.

[0014] In a preferred example, the utility model can be further configured as follows: the outer arc-shaped cover body includes an outer arc-shaped plate and two fan-shaped plates connected to the inner walls at both ends thereof, the inner hole of the two fan-shaped plates is connected to an annular seat two, the two annular seats are rotatably connected to the outer circle of the support shaft, and the outer circle surface of the outer arc-shaped plate is provided with the introduction hole.

[0015] By adopting the above technical solution, the outer arc plate and the second fan-shaped plate have the function of preventing seawater from corroding the V-shaped roller and the support shaft. Since the annular seat 2 is rotatably connected to the support shaft, the outer arc cover can rotate in a circle along the support shaft.

[0016] In a preferred example, the utility model can be further configured as follows: two second guide roller assemblies are connected to the outer circular surface of the outer arc plate at intervals, the introduction holes are provided between the second guide roller assemblies, the minimum gap between the second guide roller assemblies is smaller than the inner diameter of the introduction holes, the second guide roller assembly includes a second guide roller body and a support seat 2 rotatably connected at both ends thereof, and the end of the support seat 2 away from the second guide roller body is connected to the end of the outer arc cover body.

[0017] By adopting the above technical solution, when the cable passes through the introduction hole, the cable is rollingly connected with the second guide roller body respectively, which reduces the probability of large friction between the cable and the introduction hole and prolongs the service life of the cable.

[0018] In a preferred example, the utility model can be further configured as follows: the outer circles of both ends of the support shaft are respectively covered with nylon spacers, one end of the nylon spacer contacts the V-shaped roller, and the other end contacts the inner wall of the U-shaped mounting seat, and the two sides of the U-shaped mounting seat are respectively clamped with waterproof covers.

[0019] By adopting the above technical solution and using a nylon spacer, the erosion of the support shaft by seawater is reduced. By using a waterproof cover, the erosion of the rotating connection between the support shaft and the U-shaped mounting seat by seawater is reduced, the probability of the cable guide roller getting stuck during rotation is reduced, and the stability and service life of use are improved.

[0020] In summary, the present invention includes at least one of the following beneficial technical effects:
