When a certain column is damaged, it is not convenient to replace it. At the same time, the lengths of multiple groups of fiber ropes are different. The length of the top fiber rope is longer than the length of the bottom fiber rope. If the multiple groups of fiber ropes are tightened at the same time, the tightness of the multiple groups of fiber ropes will be different. If one group of fiber ropes is too loose, people cannot hold the fiber ropes firmly when walking on the gangway, and people are prone to fall. Utility Model Content

[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0022] Reference Figure 1-4, is an embodiment of the utility model, which provides a ship dock gangway, the ship dock gangway comprises a board body 1, the board body 1 is an arch with the middle higher than the two ends, a plurality of mounting frames 2 are arranged on both sides of the board body 1, a column 3 is slidably inserted in each mounting frame 2, a fixing hole 4 is arranged on both sides of one end of the board body 1, each fixing hole 4 is provided with a plurality of sets of steel wire ropes 5, one end of the steel wire rope 5 is wound around the fixing hole 4 or the steel wire rope 5 is fixed to the fixing hole 4 by other fasteners, the steel wire rope 5 slides through a plurality of columns 3 in turn, the top, middle end and bottom of the column 3 are provided with through holes for the steel wire rope 5 to pass through, a tightening rope assembly 6 is arranged on the other end of the steel wire rope 5, the tightening rope assembly 6 comprises a mounting seat 601, the mounting seat 601 is fixedly arranged on both sides of the board body 1, and the two sets of mounting holes are fixed on the two sides of the board body 1. The seat 601 is fixedly arranged at one end of the plate body 1, and two sets of fixing holes 4 are fixedly arranged at the other end of the plate body 1. Multiple sets of rotating wheels 602 are rotatably arranged in the mounting seat 601, and the other end of the steel wire rope 5 is wound around the rotating wheel 602. A ratchet 603 is fixedly arranged on the side of the rotating wheel 602 away from the plate body 1, and the rotating wheel 602 rotates synchronously with the ratchet 603. The rotating shaft of the rotating wheel 602 rotates through one side of the mounting seat 601 and is provided with a crank 604. Multiple sets of stop pins 605 are slidably inserted on one side of the mounting seat 601 parallel to the axis of the ratchet 603. The stop pins 605 are inserted into the mounting seat 601 to the bottom to limit the ratchet 603, prevent the ratchet 603 and the rotating wheel 602 from rotating, and prevent the rotating wheel 602 from rotating after the steel wire rope 5 is tightened. The number of mounting brackets 2 on both sides of the plate body 1 is equal, and a number of mounting brackets 2 on each side are arranged at equal intervals, which can support the steel wire rope 5. A latch 7 is slidably inserted through the side of the mounting frame 2 , and the mounting frame 2 is connected to the column 3 via the latch 7 , so that the column 3 can be fixed and flexibly disassembled, so that the column 3 can be easily replaced.
[0023] There are three groups of steel wire ropes 5 in the fixing hole 4, and the three groups of steel wire ropes 5 slide through the top, middle and bottom of the column 3 respectively and are connected to the rotating wheel 602. The three groups of steel wire ropes 5 can make the column 3 more stable in the axial direction. There are three groups of rotating wheels 602 in the mounting seat 601, and the three groups of steel wire ropes 5 are connected to the three groups of rotating wheels 602 respectively. Since the lengths of the three groups of steel wire ropes 5 are different, the tightness of the three groups of steel wire ropes 5 can be controlled separately by the three groups of rotating wheels 602, and the tightness of the three groups of steel wire ropes 5 can be controlled manually. The three groups of rotating wheels 602 are arranged at equal intervals vertically. And the distance between the three groups of rotating wheels 602 and the nearest group of columns 3 ensures that each group of rotating wheels 602 only contacts one group of steel wire ropes 5 when the rotating wheels 602 rotate.
[0024] During use, the rotating wheel 602 is rotated by turning the crank 604, and the wire rope 5 is wound around the rotating wheel 602 and tightened with the rotation. When the crank 604 is difficult to rotate, it means that the wire rope 5 has been tightened. At this time, the stop pin 605 corresponding to the rotating wheel 602 is pushed in from the mounting seat 601, and the stop pin 605 will be inserted into the gap of the ratchet 603 to prevent the ratchet 603 from rotating, and the rotating wheel 602 is fixed. Then, the other two groups of rotating wheels 602 are rotated and adjusted to adjust the tightness of the wire rope 5. The tightness of the three groups of wire ropes 5 is kept consistent through manual control to prevent the wire rope 5 from being too loose and the person from falling down. When a certain column 3 is damaged, the wire rope 5 that has passed through it can be removed first, and the pin 7 can be taken out, and the column 3 can be removed and replaced with a new column 3. Compared with the fixed column 3, replacement is more convenient.
