Problems solved by technology

[0002] At present, the cutter suction ship in the dredging project mainly uses the traverse anchor cables on both sides of the ship to pull the cutter bridge frame to realize the traverse dredging construction. Once the anchor occurs, according to the normal operation process, the reamer must be emptied to the side of the anchor, and then the anchor should be lifted, and the anchor should be placed in a suitable position again. Carry out multiple anchoring until the bridge frame is placed on the sideline, and then the anchoring can be lowered to restart construction. During this period, a lot of time will be spent on operations, which will have a great impact on construction efficiency

Embodiment Construction

[0016] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0017] see figure 1 and figure 2 , an anti-mooring device for traversing anchors of a twisted suction ship, including a traversing anchor 1 and a traversing steel cable 2, and also includes a traversing anchor chain 3 that increases the contact area with the underwater soil and the lateral friction force, said One end of the traversing anchor chain is connected to the anchor column connecting ring 1-1 of the traversing anchor 1 through the first connecting ring 4; the other end of the traversing anchor chain 3 is connected to the end of the traversing steel cable 2 through the second connecting ring 5 The buckle 2-1.

[0018] Preferably, the first connecting ring 4 includes a U-shaped card 4-1, and the opening of the U-shaped card is equip...

Abstract

The invention relates to an anti-dragging device for a transverse moving anchor of a cutter suction dredger. The anti-dragging device comprises the transverse moving anchor and a transverse moving steel cable and is characterized in that the anti-dragging device further comprises a transverse moving anchor chain used for increasing the contact area and the transverse friction force with underwatersoil, one end of the transverse moving anchor chain is connected with an anchor column connecting ring of the transverse moving anchor through a first connecting ring, and the other end of the transverse moving anchor chain is connected with a lock catch arranged at the end of the transverse moving steel cable through a second connecting ring. By adopting the brand-new technical scheme, comparedwith the prior art, the ground gripping force of the transverse moving anchor can be effectively increased, cable distortion is prevented, the positive effect on transverse moving construction of a crane span structure of the cutter suction dredger is achieved, and the anti-dragging device is suitable for cutter suction dredger construction. In addition, the anti-dragging device further has the advantages of being simple in structure, convenient to use and the like.

Description

technical field [0001] The invention belongs to the technical field of dredging engineering, and in particular relates to an anchor-preventing device for laterally moving anchors of a cutter suction ship. Background technique [0002] At present, the cutter suction ship in the dredging project mainly uses the traverse anchor cables on both sides of the ship to pull the cutter bridge frame to realize the traverse dredging construction. Once the anchor occurs, according to the normal operation process, the reamer must be emptied to the side of the anchor, and then the anchor should be lifted, and the anchor should be placed in a suitable position again. Carry out multiple times of anchoring until the bridge frame is placed on the sideline, and then the anchoring can be lowered to restart the construction. During this period, a lot of time will be spent on operations, which will greatly affect the construction efficiency. Contents of the invention [0003] In order to solve ...
