Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a roller fairlead for ships. Background Art

[0002] A ship is a means of transport that can sail or anchor in waters for transportation or operations. The ship's roller fairlead is an important component in ship engineering. The roller fairlead is mainly used as a cable hoisting tool for ship towing cargo, anchoring, mooring and other operations, and can complete various ship towing operations quickly and efficiently.

[0003] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when using cables on ships, roller fairleads are required. Since the spacing between each traditional roller fairlead is relatively fixed, and the specifications and usage requirements of the cables are different, the traditional roller fairleads will not be able to adapt in actual use; therefore, a roller fairlead for ships is proposed to address the above problems. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0005] The technical solution adopted by the present invention to solve its technical problems is: the present invention describes a roller fairguide for ships, comprising two bases and an adjusting device, the upper surfaces of the two bases are fixedly connected with bearing columns, and the surfaces of the bearing columns are rotatably connected with the wheel body; the surfaces of the two bases are provided with placement plates, the inner walls of the placement plates are slidably connected to the base surfaces, the inner surfaces of the placement plates are fixedly connected to two support rods, both sides of the base are fixedly connected with sliders, the inner walls of the sliders are slidably connected to the surfaces of the support rods, and the base and the inner walls of the placement plates are inserted with insertion rods, the base drives the slider to slide, and the slider slides on the surface of the support rods, and after the base slides to a suitable position, the insertion rod is inserted into the base and the inner walls of the placement plates. By arranging the placement plates, support rods, sliders and insertion rods, the position of the base can be conveniently adjusted to meet different needs.

[0006] Preferably, a plurality of insertion holes are provided on the surface of the base, and the insertion rod is inserted into the inner wall of the insertion hole of the base. When the insertion rod moves, the insertion rod is inserted into the inner wall of the insertion hole of the base, and the insertion rod can be accommodated by providing the insertion hole.

[0007] Preferably, a limit block is inserted into the inner wall of the insertion rod, and the limit block is located on the side wall of the placement plate. After the insertion rod is used, the limit block is pushed to allow the limit block to be inserted into the inner wall of the insertion rod, and the limit block can limit the position of the insertion rod.

[0008] Preferably, a sliding groove is provided on the surface of the placement plate, and the inner wall of the sliding groove of the placement plate is slidably connected to the surface of the base. When the base moves, the base slides on the inner wall of the sliding groove of the placement plate. The opening of the sliding groove can facilitate the movement of the base.

[0009] Preferably, multiple fixed blocks are fixedly connected to both sides of the placement plate, and the inner walls of the fixed blocks are threadedly connected with positioning pins. After the fixed blocks are placed, the positioning pins are rotated into the inner walls of the fixed blocks and the installation points. By setting the positioning pins and fixed blocks, the position of the placement plate can be limited.

[0010] Preferably, two lubrication devices are provided on the surface of the wheel body, and the lubrication device includes an oil storage cavity, which is opened on the inner surface of the wheel body, and an oil inlet hole is opened on the upper surface of the wheel body near the oil storage cavity, and a plurality of main holes are opened on the inner surface of the base near the bearing column. The grease will be applied to the connection between the bearing column and the wheel body through the main holes. By setting the oil storage cavity, the main hole and the oil inlet hole, the support column and the wheel body can be conveniently lubricated.

[0011] Preferably, a plurality of auxiliary holes are provided on the surface of the wheel body, and a sealing plug is inserted into the inner wall of the oil inlet hole of the wheel body. After the grease enters the oil storage cavity, part of the grease will be smeared on the outer surface of the wheel body through the auxiliary holes. By setting the auxiliary holes, the wheel body surface and the cable connection can be lubricated conveniently.

[0012] The utility model is beneficial in that:

[0013] 1. When the wheel body of the utility model needs to be used, the placement plate is placed in a suitable position, and then the positioning pin is rotated into the fixed block and the installation point, and then the base is pushed to slide on the inner wall of the slide groove of the placement plate.

By setting the entire device, the spacing of the wheel bodies can be conveniently adjusted to meet the actual use needs of the cable.

[0014] 2. When the wheel body and the bearing column need to be lubricated, the utility model pulls out the sealing plug, then inserts the grease gun into the oil inlet hole, and then squeezes the grease into the oil storage cavity of the wheel body. At the same time, the grease is applied to the surface of the bearing column and the outer surface of the wheel body through the main hole and the auxiliary hole respectively. After lubrication is completed, the sealing plug is reinserted into the oil inlet hole. By setting up the entire device, the wheel body and the support column can be lubricated conveniently, reducing the situation where traditional lubrication requires disassembly of the entire equipment.
