Description

Technical Field

[0001] The utility model relates to the technical field of handrail ropes, in particular to a marine handrail rope. Background Art

[0002] For the safety of ships, handrails are usually installed in dangerous places on the ship. For example, the handrail rope is one of them, which improves the safety of crew members or passengers.

[0003] In order to improve the safety of the marine handrail rope after installation, the prior art has made many improvements to the marine handrail rope. For example, the patent with the publication number CN204688368U discloses a marine knotted boarding rope, especially a marine knotted boarding rope with convex knot sleeves woven on the rope. The technical solution is: on various ropes, many spaced convex knot sleeves are wound, sleeved and knitted with fiber thin ropes, so that many spaced convex knot sleeves are formed on the rope. This rope can effectively ensure the stability of the grip of ship passengers at the rope guardrail or handrail position, and improve the safety of ship passengers when walking. The beneficial effect is that it can improve the safety of crew members grasping the rope.

[0004] The above patent has obvious beneficial effects, but there are still the following deficiencies in actual operation:

[0005] In reality, the handrail rope is installed between two columns, and the number of handrail ropes between the two columns is multiple. In the prior art, most of the two ends of the handrail rope are installed by a plurality of bolts. Therefore, the installation of the handrail rope is relatively troublesome. And if a certain handrail rope is damaged later, if only the damaged handrail rope needs to be replaced, it is relatively cumbersome. Therefore, it is urgent to improve the marine handrail rope in this field to solve the defects of the prior art. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a marine handrail rope, which is convenient for the installation and later maintenance and replacement of the handrail rope unit.

[0007] To achieve the above object, the utility model provides the following technical solution: A marine handrail rope includes a plurality of groups of handrail rope units arranged between two columns. A length adjustment unit is arranged in the middle position of each group of handrail rope units. Plug-in blocks are arranged at both ends of each group of handrail rope units. A plurality of plug-in grooves adapted to the plug-in blocks are arranged on the side surfaces of the two columns. A limiting screw rod is inserted into the upper ends of the two columns, and the limiting screw rod penetrates through a plurality of plug-in blocks.

[0008] Preferably, each handrail cable unit includes a first cable and a second cable. The length adjustment unit is arranged between each first cable and the second cable. Each length adjustment unit includes a first riveting ring and a second riveting ring respectively riveted to the opposite ends of the first cable and the second cable. A connecting sleeve and a connecting column are respectively rotatably connected to the ends of the first riveting ring and the second riveting ring. The connecting column is threadedly connected to the connecting sleeve.

[0009] Preferably, a limiting ring is threadedly connected to the side of the connecting column, and first clamping platforms in the shape of polygons are respectively formed on the sides of the connecting sleeve and the connecting column.

[0010] Preferably, third riveting rings are respectively riveted to both ends of each handrail cable unit. A first threaded column is fixedly connected to the side of each plug-in block, and a first threaded hole adapted to the first threaded column is formed at one end of the third riveting ring.

[0011] Preferably, mounting seats are respectively arranged at the lower ends of the two columns, and the lower end of the limiting screw rod is threadedly connected to the upper end of the mounting seat.

[0012] Preferably, protective blocks are respectively arranged at the upper ends of the two columns. Step holes adapted to the limiting screw rod are respectively formed at the upper ends of the two columns. A second threaded column is fixedly connected to the lower side of the protective block. A second threaded hole adapted to the second threaded column is formed at the upper end of the limiting screw rod. A second clamping platform in the shape of a polygon is formed on the side of the protective block.

[0013] Preferably, reminder signs are respectively pasted on the sides of the two columns, and all the plug-in slots are completely covered by the reminder signs.

[0014] Aiming at the deficiencies of the prior art, the utility model provides a marine handrail cable, which overcomes the deficiencies of the prior art. The beneficial effects of the utility model are as follows:

[0015] 1. In the utility model, when the handrail cable unit needs to be installed, the columns are installed at the positions on the hull to be protected. The plug-in blocks at the ends of a plurality of first cables and second cables are inserted into the plug-in slots. Steps adapted to the plug-in blocks are formed in the plug-in slots. The plug-in blocks are clamped in the plug-in slots. After the plug-in blocks are installed, the limiting screw rod penetrates through the upper ends of the columns, and the limiting screw rod passes through a plurality of plug-in blocks to further limit the positions of the plug-in blocks, which is convenient for installation and later maintenance and replacement.

[0016] 2. In the utility model, by arranging the length adjustment unit, the connecting column is threadedly connected to the connecting sleeve, and a tool such as a wrench is clamped at the position of the first clamping platform to tighten the connecting column and the connecting sleeve, so as to adjust the first cable and the second cable, which is convenient for adjusting the sag in the middle of the handrail cable unit.

[0017] 3. In the present utility model, the first threaded post on the side of the plugging block is threadedly connected to the first threaded hole for installing the plugging block. In the later stage, if it is necessary to replace the handrail cable unit, there is no need to replace the plugging block, and the plugging block can be reused, reducing the later maintenance cost. The mounting seat is installed on the hull through fasteners. The lower end of the limit screw rod is threadedly connected and installed with the upper end of the mounting seat. When the column is damaged, the column can also be replaced separately, further reducing the later maintenance cost.
