[0017] By adopting the above technical solution, it is possible to avoid pulling the cable end when the spiral cable slides on the wire rope, thereby ensuring the safe operation of the line.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. The utility model installs the bottom fixing plate and the top fixing plate on the steel plate, and installs the spiral cable through the steel wire rope connected by the buckles on the bottom and top fixing plates. The cable is easy to install and no longer needs to be fixed with a drag chain, which reduces the installation cost. In addition, no drag chain is used, so that the space utilization on the ship is maximized.

[0020] 2. The spiral cable of the utility model extends to the junction box on the movable deck through the cable guide rod, and the cable guide rod is fixedly connected to the movable deck. The cable guide rod is used to support the spiral cable so that the spiral cable can be stably routed to the junction box. When the movable deck rises, the spiral cable extends, and when the movable deck descends, the spiral cable shortens. The cable will not be in a mess during operation, ensuring that the line can run safely when the movable deck is raised or lowered.

[0021] 3. The utility model provides a fixing piece for binding the spiral cable on the wire board to prevent the spiral cable from pulling the cable end when sliding on the wire rope, thereby ensuring the safe operation of the line. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] like Figure 1 As shown, a spiral cable installation device for a ship includes a steel plate 1 as a bulkhead, a bottom fixing plate 2 and a top fixing plate 9 are respectively installed on the bottom and top of the steel plate 1; a bottom buckle 3 is arranged on the bottom fixing plate 2, and a threading plate 5 is arranged on the steel plate 1 close to the bottom buckle 3; a wire passing plate 12 is arranged on one side of the threading plate 5; a top buckle 8 is arranged on the top fixing plate 9; a steel wire rope 4 is arranged between the bottom buckle 3 and the top buckle 8, and a spiral cable 6 is sleeved on the steel wire rope 4. The spiral cable 6 is installed by the steel wire rope 4 connected by the buckles on the bottom and top fixing plates, which is convenient for cable installation, and no drag chain is used for fixing, thereby reducing the installation cost. In addition, no drag chain is used, so that the space utilization on the ship is maximized.

[0028] A plurality of U-shaped openings are provided on the threading plate 5, and a steel wire rope 4 is provided in the U-shaped openings. The plurality of U-shaped openings separate the steel wire ropes 4, so that the spiral cables 6 are arranged neatly. The spiral cable 6 is extended to the junction box on the movable deck 15 through the cable guide 7, and the cable guide 7 is fixedly connected to the movable deck 15. The cable guide 7 is used to support the spiral cable 6 so that the spiral cable can be stably routed to the junction box. When the movable deck 15 rises, the spiral cable is extended, and when the movable deck 15 is lowered, the spiral cable is shortened. The cables will not be in a mess during operation, ensuring that the lines can operate safely when the movable deck 15 is raised or lowered.

[0029] A reinforcing plate 14 is provided on the top fixing plate 9, and the two sides of the reinforcing plate 14 are fixedly connected to the top fixing plate 9 and the steel plate 1 respectively. The reinforcing plate increases the structural strength and improves the service life of the device. A fixing member 13 for binding the spiral cable 6 is provided on the wire plate 12. It prevents the spiral cable 6 from pulling the cable end when sliding on the wire rope 4, ensuring the safe operation of the line.

[0030] like Figure 2As shown, the cable guide rod 7 is a structure in which a bracket 11 is arranged on a bracket 10, and the bracket 10 is fixed on a movable deck 15, and the bracket 11 is at a right angle to the bracket 10. There are multiple brackets 11. Multiple spiral cables 6 can be supported as needed to ensure that the spiral cables 6 are arranged neatly.

[0031] One end of the spiral cable 6 is connected to the power supply, and the other end is connected to the device through a junction box.

[0032] The installation scheme of the spiral cable of the utility model is as follows:

[0033] Step 1: Install the bottom fastener 3. The bottom fastener 3 is a bolt connection. Adjust the bottom fastener 3 to a position of 20% to 30%.

[0034] Step 2: Install the top fastener 8. The top fastener 8 is in the form of a bolt connection.

[0035] Step 3: Measure the upper and lower distances and cut the wire rope 4 (including the length of the buckle joint).

[0036] Step 4: Insert the spiral cable 6. Press buckles at both ends of the steel wire rope 4.

[0037] Step 5: Connect the buckled steel wire rope 4 to the buckled parts at both ends.

[0038] Step 6: Adjust the bottom fastener 3 and the top fastener 8, and tighten the wire rope 4.

[0039] When the movable deck 15 needs to be lowered during operation, the cable guide rod 7 drives the spiral cable 6 to be compressed downward until the lower limit position of the movable deck 15 is reached. Figure 3 When the movable deck 15 needs to be lifted upward, the cable guide rod 7 drives the spiral cable 6 to extend upward until the upper limit position of the movable deck 15 is reached. Figure 4 .
