Description

TECHNICAL FIELD

[0001] The present application relates to an extraction device and method, belonging to the technical field of extraction. BACKGROUND

[0002] With the rapid development of port construction in China, a large number of newly built wharfs and berths are put into operation quickly.

[0003] In recent years, the problem of siltation behind the large port high-pile wharf has become more and more serious. The siltation height of the mud surface increases year by year, which reduces the safety performance of the wharf structure. Under the time factor, affected by the tide, wind and wave, or the upgrading of wharf berthing, it is necessary to clean and construct the silted soil and undisturbed soil under the wharf and behind the wharf. At the same time, in order to meet the increasing demand for water depth of large ships berthing, the wharf front is regularly dredged, which causes the difference in mud surface height between the front and back of the wharf to increase continuously, which easily causes the pile foundation to be damaged and cracked, and there is a serious safety hazard.

[0004] The current research bottleneck of wharf back dredging and load reduction mainly reflects two aspects: first, due to the dense arrangement of pile foundations under high-pile wharfs, the narrow water area behind the wharf, and the limited water depth, the traditional dredging construction facilities are limited in size and water depth, and the existing large and medium-sized mature dredging equipment cannot enter the back of the wharf for dredging operation; second, the traditional dredging technology has problems such as the need for modification of the construction ship, high cost, low efficiency, aggravation of siltation behind the wharf after dredging, and poor dredging and load reduction effect.

[0005] The current research on port wharf dredging and load reduction technology is mainly carried out for the wharf front, harbor and channel. In the process of dredging the wharf front water area and channel, traditional jet dredging ships, chain bucket dredgers, shovel dredgers, grab dredgers, hydraulic suction dredgers, rake suction dredgers, and pneumatic scouring methods are mainly used. Such dredging projects are mainly implemented by using mud pumps for direct suction and artificial high-pressure water guns for scouring, which has low efficiency, great safety hazards, and poor quality control. In addition, in the area behind the wharf, due to the dense arrangement of pile groups under high-pile wharfs, the traditional dredging ships and dredging ships are limited by their own size and cannot enter the back of the wharf for dredging operation.

[0056] The above extraction device can solve the problem that traditional large equipment cannot perform extraction in narrow spaces. The specific implementation of the extraction device is illustrated below with reference to the attached diagram.

[0057] Combination Figure 1 and Figure 2As shown, the moving mechanism includes a base plate 12, a roller 14, a first drive motor 15 and a traction rope 16; one end of each of the traction ropes 16 is fixedly connected to the ends of the base plate 12, and the other end of each of the traction ropes 16 is connected to the output end of a first drive motor 15; the base plate 12 is connected with an extension drive mechanism and an extraction drive mechanism 7; the roller 14 is installed below the base plate 12; the first drive motor 15 is signal-connected to the control system 20, and the first drive motor 15 changes the length of the traction rope 16 to drive the base plate 12 and the extension drive mechanism and the extraction drive mechanism 7 above the base plate 12 to move positions according to the signal of the control system 20.

[0058] In the embodiment, the moving mechanism adopts two rows of four rollers 14, the ends of the base plate 12 are provided with fixing rings for fixing the traction ropes 16, two traction ropes 16 are fixedly connected to the ends of the base plate 12, and a total of four traction ropes 16 are connected, each traction rope 16 is connected with a first drive motor 15, and a total of four first drive motors 15 are connected, each first drive motor 15 is fixedly connected with a first stake body 19, and a total of four first stake bodies are connected, under the signal driving of the control system 20, the first drive motor 15 drives the traction rope connected therewith to change the position of the base plate 12, and the roller 14 below the base plate 12 changes the sliding friction into rolling friction to reduce the friction.

[0060] In combination with Figure 1 and Figure 2 As shown, in the embodiment, the extension drive mechanism adopts a hydraulic system, including a hydraulic cylinder 10 and a piston rod 11; the fixed end of the hydraulic cylinder 10 is fixedly connected to the moving mechanism; the piston end of the hydraulic cylinder 10 is connected to the connecting end of the piston rod 11, the hydraulic cylinder 10 drives the output end of the piston rod 11 to extend or retract the cylinder body of the hydraulic cylinder 10 according to the signal of the control system 20, and the output end of the piston rod 11 is fixedly connected to the extension end of the telescopic pipe 6.

[0061] In combination with Figure 1 and Figure 2 As shown, in the embodiment, the upper end surface of the base plate 12 is fixedly connected with a frame 13, and the frame 13 is fixedly connected with the fixed end of the hydraulic cylinder 10 through a T-shaped connecting sleeve 9.

[0062] As shown in Figure 1 and Figure 3 In order to facilitate extraction, the extension end of the telescopic pipe 6 is provided with a material taking structure for transmitting the pretreated material to be extracted to the extension end of the telescopic pipe 6.

[0063] When the material to be extracted is silt, such as Figure 3 As shown, in this embodiment, the object-retrieving structure includes a reamer 1, a blade cover 3, and a second drive motor 4. The reamer 1 is disposed inside the blade cover 3, which is an open cavity structure adapted to the shape of the reamer 1. The blade cover 3 also has a transmission port connecting to the telescopic tube 6. The second drive motor 4 is mounted on the blade cover 3 and is signal-connected to the control system 20.

[0064] like Figure 1 and Figure 3 As shown, two ear plates 5 extend from the outer surface of the blade cover 3, as...

After adjustment, the direction of the opening of the blade cover 3 is fixed. The retrieval structure, which can adjust the direction of the opening and fix the angle after adjustment, allows the retrieval structure of the extraction device of the present invention to better fit the retrieval angle. At the same time, when the extraction device of the present invention extracts sludge-like substances with a certain degree of stickiness, the retrieval structure may be stuck to the substance to be extracted and cannot work normally. Rotating the direction of the opening of the blade cover 3 makes it easier to remove the retrieval structure from the stuck state, reducing the working pressure of the telescopic drive mechanism for telescopic removal.

After the silt sucked into the container 8 is screened by the filter layer 801, the silt and sand are left above the filter layer, and are discharged to a dredging ship or other receiving equipment through the silt pump 806 and the silt outlet pipe 807, and the seawater is filtered below the filter layer 801 and is discharged from the container 8 into the water through the water outlet pipe 803. This receiving mode of solid-liquid separation can reduce the storage and transportation pressure caused by seawater in the extracted substances.
