Description

Technical Field

[0001] The present invention belongs to the technical field of marine navigation aids, and particularly relates to a rope connection device. Background Art

[0002] During the hoisting and inspection operations of navigation aids, the hook of the ship's crane needs to be connected to the lifting lug of the navigation aid through a steel wire rope. When performing the operation, first, the lifting wire rope of the navigation aid needs to be passed through the lifting lug of the navigation aid. The distance between the ship's operators and the navigation aid in the water is relatively far, and the lifting wire rope of the navigation aid is thick, heavy and has great toughness. Therefore, it is difficult to directly pass the steel wire rope through the lifting lug of the navigation aid. To pass the steel wire rope through the lifting lug of the navigation aid, the crew generally first connects the steel wire rope to a relatively light guiding rope during the operation, then passes the guiding rope through the lifting lug, and finally pulls the lifting wire rope of the navigation aid into the lifting lug through the guiding rope.

[0003] To pass the guiding rope through the lifting lug, part of the guiding rope needs to be manually thrown at a suitable position on the lifting lug from a long distance before the operations of hooking the rope and pulling the rope can be carried out. The accuracy rate of manually throwing the guiding rope from a long distance is relatively low. Especially when the target is a large ship with a high freeboard or when operating in a high wind and wave environment, it usually takes at least 2 to 3 throws to successfully throw the guiding rope. In addition, the operation of threading the rope through the lifting lug usually requires two people to cooperate to complete, which not only reduces the operation efficiency and increases the labor cost, but also increases the safety risk of the operation at the ship's side.

[0004] Therefore, there is an urgent need for a technical solution for efficiently threading the guiding rope into the lifting lug. Summary of the Invention

An upper limiting groove 113 extending inward therefrom and for the upper limiting member 112 to reciprocate is provided on the upper hook end face 111. The upper limiting member 112 has an upper fastening portion 1121. The first end of the upper limiting member 112 is an upper limiting convex portion 1122. When the upper limiting convex portion 1122 protrudes from the upper hook end face 111 along the upper limiting groove 113, the upper fastening portion 1121 fastens the upper buckle member 21. When the upper limiting convex portion 1122 enters the inside of the upper limiting groove 113 along the upper limiting groove 113, the upper fastening portion 1121 disengages from the upper buckle member 21. The second end of the upper hook member 11 is connected to the first end of the hook connecting member 13. The first end of the lower hook member 12 is provided with the lower buckle member 22 on the side through a lower limiting member 122. The first end of the lower hook member 12 has a lower hook end face 121. A lower limiting member 122 is provided inside the first end of the lower hook member 12. A lower limiting groove 123 extending inward therefrom and for the lower limiting member 122 to reciprocate is provided on the lower hook end face 121. The lower limiting member 122 has a lower fastening portion 1221. The first end of the lower limiting member 122 is a lower limiting convex portion 1222. When the lower limiting convex portion 1222 protrudes from the lower hook end face 121 along the lower limiting groove 123, the lower fastening portion 1221 fastens the lower buckle member 22. When the lower limiting convex portion 1222 enters the inside of the lower limiting groove 123 along the lower limiting groove 123, the lower fastening portion 1221 disengages from the lower buckle member 22. The second end of the lower hook member 12 is rotatably connected to the rotating portion 131, and the second end of the lower hook member 12 is in transmission connection with the transmission portion 32. The lower hook member 12 rotates around the rotating portion 131 to enable the lower buckle member 22 to be snap-connected to the upper buckle member 21. The lower hook member 12 rotates around the rotating portion 131 to enable the upper limiting convex portion 1122 to be in contact and cooperation with the lower hook end face 121, and at the same time enable the lower limiting convex portion 1222 to be in contact and cooperation with the upper hook end face 111. Among them, the upper rope connecting portion 211 and the lower rope connecting portion 221 are rope perforations.

[0059] The working principle of this embodiment:

[0060] 1) First, connect one end of the guide rope to the upper rope connecting part 211, and install the upper buckle 21 with the connected guide rope on the side of the upper hook 11 through the upper buckling part 1121; connect the other end of the guide rope to the lower rope connecting part 221, and install the lower buckle 22 with the connected guide rope on the side of the lower hook 12 through the lower buckling part 1221;

[0061] 2) Then, the staff holds the handshake part 31 by hand, picks up the entire rope connecting device, and inserts the upper hook 11 into the corresponding buoy lifting lug;

[0062] 3) Subsequently, the staff pulls the handshake part 31 downward by hand, so that the transmission part 32 moves downward and drives the lower hook 12 to rotate forward around the rotating part 131 until the upper hook end face 111 contacts and cooperates with the lower hook end face 121, and at the same time makes the upper buckle 21 contact and cooperate with the lower buckle 22 and be buckled and connected; at this time, the upper hook 11 and the lower hook 12 contact to form a ring-shaped hook passing through the lifting lug;

[0063] 4) During the process of the upper hook end face 111 contacting and cooperating with the lower hook end face 121: the upper limit convex part 1122 of the upper limit part 112 contacts and cooperates with the lower hook end face 121, and the reaction force of the lower hook end face 121 contacting the upper limit convex part 1122 makes the upper limit convex part 1122 enter the inside of the upper limit groove 113 along the upper limit groove 113, and finally makes the upper buckling part 1121 disengage from the upper buckle 21; at the same time, the lower limit convex part 1222 of the lower limit part 122 contacts and cooperates with the upper hook end face 111, and the reaction force of the upper hook end face 111 contacting the lower limit convex part 1222 makes the lower limit convex part 1222 enter the inside of the lower limit groove 123 along the lower limit groove 123, and finally makes the lower buckling part 1221 disengage from the lower buckle 22; therefore, the upper buckle 21 and the lower buckle 22 are disengaged from the hook assembly 1 while being buckled and connected;

[0064] 5) Finally, the staff pushes the handshake part 31 upward by hand, so that the transmission part 32 moves upward and drives the lower hook 12 to rotate reversely around the rotating part 131; at this time, the upper hook 11 and the lower hook 12 have an opening, so that the hook assembly 1 can disengage from the lifting lug; the rope buckle assembly 2 and the guide rope are retained on the lifting lug, completing the action of passing the guide rope through the lifting lug.

[0065] The beneficial effects of this embodiment are as follows: in this embodiment, by the staff holding the handshake part 31 and sequentially pulling and pushing the handshake part 31, the action of passing the guide rope through the lifting lug can be completed, thereby improving the efficiency of the staff passing the guide rope through the lifting lug and ultimately improving the working efficiency of the buoy operation; at the same time, in this embodiment, the length of the handshake assembly 3 can be adjusted according to the actual working environment, so as to meet the working requirements of the staff for passing the guide rope over a long distance.
