Description

TECHNICAL FIELD

[0001] The present application relates to the dredging engineering technical field, specifically to a dredging work ship. BACKGROUND

[0002] Dredging engineering refers to the earthwork engineering for widening and deepening water area by using dredging vessels or other tools and manual labor for underwater excavation. The design of the dredging engineering trench stress diagram changes the internal structure of the water flow by changing the geometric boundary of the water flow, so that the newly formed water flow structure not only ensures that the sediment does not accumulate in the channel (at least before the next flood season arrives), but also transports the sediment entering the trench to the lower trench to maintain the stability of the channel.

[0003] The traditional dredging work ship generally adopts the mode of suspending the bucket by steel wire rope. This mode realizes efficient sand excavation by using the self-weight of the bucket. However, during the operation, the steel wire rope needs to be extended downward from the end of the erected boom to the vicinity of the water bottom. Due to the long length of the rope, it is easily disturbed by external environmental factors, thereby affecting the position accuracy of the bucket device. CONTENT OF THE UTILITY MODEL

[0011] Further, the inner wall of the fixing member is made of rubber and contacts the first steel rope and the second steel rope.

[0012] Through the above scheme, the inner wall of the fixing member is made of rubber, which can avoid friction between the first steel rope, the second steel rope and the inner wall of the fixing member, thereby prolonging the service life of the first steel rope and the second steel rope.

[0013] Further, the side surface of the two shovels away from each other is provided with a screen.

[0014] Through the above scheme, the screen can be installed to discharge water between the two shovels, thereby reducing the weight and facilitating the dredging work of the river.

[0018] Through the above scheme, the cooperation of the binding members and the multi-link extension rods can improve the stability of the shovel and limit the plurality of first steel ropes and the second steel ropes, thereby reducing the swing of the shovel.

[0019] Further, the two shovels are subjected to rust prevention treatment, and the inner wall of the plurality of binding members is made of rubber.

[0020] Through the above scheme, the rust prevention treatment of the shovel can improve the service life of the shovel, and the inner wall of the binding member is made of rubber, which can reduce the wear of the first steel rope and the second steel rope.
