Abstract
A drag sweep construction system of an automatic navigation drag suction dredger comprises a dredger body and a sweep device, wherein the sweep device comprises a left drag, a left drag, a steel cable and a drag pipe, the right and the left drags are fixed on the dredger body through the drag pipe, and the two ends of a sweep rope are respectively connected on the right and the left drags. In the utility model, the sweep track width of the automatic navigation drag suction dredger is extended to the width between the two drags from the width of two drags, so the single sweep scope of the automatic navigation drag suction dredger is increased, the sweep speed of the automatic navigation drag suction dredger is greatly increased, and the sweep effect is greatly improved.
Description
Technical field
The utility model relates to boats and ships construction equipment technical field, and the wirerope that drags that especially relates to a kind of trailing suction hopper dredger is swept shallow construction system.
Background technology
Free floating suction dredge(r) construction generally with slightly dig, essence is dug, sweep shallow is an engineering construction process, in large-area channel excavation or maintenance engineering construction, it is minimum that the construction later stage is swept shallow staged construction efficient, labor intensity of operating staff is big, the poor effect of dredging.To sweep shallow efficient in order improving, also to have employing to drag wirerope or anchor chain to sweep shallow construction at free floating suction dredge(r) ship stern in the prior art, as shown in Figure 1, but practical effect is undesirable.
The utility model content
Goal of the invention of the present utility model is that the wirerope that drags of inventing a kind of trailing suction hopper dredger sweeps shallow construction system, so that address the above problem.
In order to realize the foregoing invention purpose, the technical solution adopted in the utility model is as follows:
A kind of wirerope that drags of trailing suction hopper dredger is swept shallow construction system, comprise hull and sweep shallow device, describedly sweep shallow device and comprise right drag head, left drag head, sweep shallow hawser and rake pipe, described right drag head and described left drag head all are fixed on the described hull by described rake pipe, and described two ends of sweeping shallow hawser are connected on described right drag head and the described left drag head.
It is described that to sweep shallow hawser be wirerope.
Described right drag head and described left drag head lay respectively at the left and right sides of described hull.
The beneficial effects of the utility model are as follows:
1. the utility model makes the shallow track width of sweeping of free floating suction dredge(r) extend to width between two drag heads from the width of two drag heads, increased the shallow scope of sweeping of free floating suction dredge(r) single, increased the shallow speed of sweeping of free floating suction dredge(r) greatly, significantly improved and swept shallow effect.
2. the utility model is simple in structure, and is cheap for manufacturing cost.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is a structural scheme of mechanism of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, describe the utility model optimized technical scheme in detail.
A kind of wirerope that drags of trailing suction hopper dredger is swept shallow construction system as shown in Figure 2, comprise hull 4 and sweep shallow device, describedly sweep shallow device and comprise right drag head 1, left drag head 2, wirerope 3 and rake pipe 5, described right drag head and described left drag head all are fixed on the described hull by described rake pipe, the two ends of described wirerope 3 are connected on described right drag head and the described left drag head, and described right drag head and described left drag head lay respectively at the left and right sides of described hull.
The utility model is fixed on two drag heads of free floating suction dredge(r) by two of wirerope 3 is linked, in the process of dredging, drag wirerope 3 simultaneously, wirerope 3 dragged mud in the back when drag head was dredged in front, drag the peak head (shallow point) in the flat two drag head scopes, make the shallow track width of sweeping of free floating suction dredge(r) extend to width between two drag heads from the width (as shown in Figure 1) of two drag heads, increased the shallow scope of sweeping of free floating suction dredge(r) single, increased the shallow speed of sweeping of free floating suction dredge(r) greatly, significantly improved and swept shallow effect.Operation adjusts slightly and promptly can drag back and forth as the construction operation of dredging at ordinary times in the construction, and tune freely, and is flexible to operation.
Utilize free floating suction dredge(r) self to drag wirerope 3 to sweep shallow construction in the big zone of construction area, drag head digs in front, wirerope 3 drags in the back, wirerope 3 two ends are controlled at desired depth, cut jut on the mud face with wirerope 3 as cutting blade, through the dilatory several times cutting of wirerope 3, the peak head in wirerope 3 scopes be cut drag flat.Wirerope 3 is in the moving process of mud Orly, isolated mud face projection is produced the cutting force of level, even be lifted (the isolated non-whole verticals of mud face projection) along with resistance increases wirerope 3, still can obliquely cut isolated mud face projection down, making wirerope 3 can remain at the mud face is the isolated projection mud layer of cutting, through towing cable construction repeatedly, reach the purpose of the shallow point of efficient cleaning.
More than by the detailed description of concrete and preferred embodiment the utility model; but those skilled in the art should be understood that; the utility model is not limited to the above embodiment; all within spirit of the present utility model and principle; any modification of being done, be equal to replacement etc., all should be included within the protection domain of the present utility model.
