Description

Technical Field

[0001] The present invention relates to the technical field of ship equipment, and in particular to a ship cable clamp loading and unloading structure and a use method thereof. Background Art

[0002] Every time the dredging vessel changes the cable or the grab bucket, it is necessary to remove the cable and remove the entire cable clamp to the deck surface for operation. After the cable is removed from the grab bucket electrical box, the unloading of the cable clamp requires the cooperation of the small steel wire of the deck surface winch. The previous method is: prepare a 1-meter-long, 18mm diameter steel wire buckle, a 6T shackle, a 3T conventional pulley, a 2-meter-long nylon rope, a 40-meter-long nylon rope, and then pull the deck surface winch small steel wire to a sufficient length as a traction wire. Two operators climbed up the upper and middle part of the bar with a 40-meter-long nylon rope and worked directly above the cable clamp. At the work area, fasten your safety belt, wrap the wire buckle around the bottom of the guardrail of the working area, connect the pulley with a shackle, tie a 2-meter small nylon rope to the end of the shackle, and tie the other end to the railing. Then throw the long nylon rope to the deck, pull up the small steel wire, pass it through the pulley, throw the long nylon rope down to the deck, untie the short nylon rope, loosen the pulley until it is stressed, and the deck personnel then pull the traction wire down to the cable clamp, connect the cable clamp with a shackle, and after the cable clamp is loosened, it can be pulled out and slowly lowered to the deck.

[0003] However, after going through the entire operation process above, several defects were found: 1. The guardrail for hanging wire buckles does not have enough pulling force; the position is too low, which is inconvenient to operate and easy to pinch hands; 2. It is very difficult to pull the traction wire up from above. The diameter of the conventional pulley slide is not large enough, and the traction wire cannot pass directly through the pulley. The pulley cover needs to be opened and the traction wire needs to be installed in, which is cumbersome and unsafe; 3. When the pulley and traction wire need to be untied after completion, it is time-consuming and laborious to pull up the pulley with the traction wire; 4. The unfastening operation of the buckle is cumbersome and inconvenient to operate during use. Summary of the invention

[0042] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As a preferred technical solution of the present invention, the first self-locking shackle 3, the second self-locking shackle 5 and the third self-locking shackle 10 have the same structure, and all include a shackle seat 11 and a cross bar 12 slidably connected to both sides of the shackle seat 11, and the two cross bars 12 are movably abutted against each other at one end thereof, a slider 131 is fixedly provided on the cross bar 12, and a slide groove 13 for sliding of the slider 131 is provided on the shackle seat 11, and an elastic telescopic rod 132 is provided between the inner wall of the slide groove 13 and the slider 131.

[0043] Furthermore, an extrusion slope 121 is formed at one end of the two cross bars 12 that are close to each other. The extrusion slope 121 is formed at a side away from the shackle seat 11 .

[0044] Specifically, when the self-locking shackle is used, the staff only needs to push the part to be connected to the extrusion inclined surface 121, so that the extrusion inclined surface 121 is subjected to force to drive the two cross bars 12 on the shackle seat 11 to move relatively away, so that the part to be connected is placed between the shackle seat 11 and the cross bar 12, and the cross bar 12 is reset and moved back under the push of the elastic telescopic rod 132, thereby realizing the connection locking of the part to be connected.

[0045] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7and Figure 8 As a preferred technical solution of the present invention, each cross bar 12 is slidably connected with a first wedge block 122 and a second wedge block 123 that are movably opposed to each other. A slot 124 is opened on one of the cross bars 12 for inserting the second wedge block 123 in the other cross bar 12, and a force plate 125 is fixed on the top of the first wedge block 122.
