Abstract
The utility model relates to an improved structure of a mud suction port of a cutter suction dredger, which comprises a mud suction port pipe and a shield which is installed at the outer side of a main shaft and is connected with the mud suction port pipe, and is characterized in that: an arc guardrail is arranged at the outer side of the mud suction port, one end of the arc guardrail is welded onto the outer wall of the shield, and the other end of the arc guardrail is welded onto the outer wall of the mud suction port pipe which is positioned at the lower edge of the mud suction port. The technical scheme is adopted, i.e. the arc guardrail is welded at the mud suction port and effectively solves the dredging problem under the condition of basically not influencing the flow condition of the mud suction port, so the structure greatly reduces the pump blocking condition, and the problem that time and labor are cost to clear a pump is solved; the self maintaining time is reduced; and the improved structure has the advantages of easiness for handling and the like when the port is blocked.
Description
Technical field
The utility model belongs to the technology for environmental dredging field, particularly relates to the architecture advances that a kind of cutter suction dredger is inhaled the mud mouth.
Background technology
At present, in the dredging industry, reamer is mainly used in the excavation and the dredging of underwater soil, when dredging operation, can run into various geological conditions; For example in dredging backfill process, the backfill soil property is main with mud, wherein contains a large amount of stones, fishing net, also has a certain amount of foundry loam; Regular meeting stifled pump occurs, blocks up, sticks with paste phenomenon such as reamer in the time of in the operation, needs cleaning in time after the above-mentioned situation occurs, stops up suction mud mouth than bigger material in a large number otherwise cause easily; Block up thereby cause, this moment, mouthful place's vacuum action part was used for holding foreign material, can't all be used for aspirating the dredging thing; Cause vacuum excessive easily, moment serious cavitation erosion, the shake car takes place.
Existing solve the problems of the technologies described above general employing and inhale the mud mouth and be provided with the groined type grid and will inhale the mud mouth and separate and be several little suction mud mouths, the foreign material that can effectively reduce larger volume like this get into the dredging pipeline, still reduce to dredge the sectional area that passes through like this; When the dredging foreign material are being inhaled under the mud mouth vacuum action; Suction is stuck in the grid place easily to inhaling the mud mouth, and the grid of this kind structure bothers when cleaning very much; The maintenance activity time is longer, influences the overall progress of dredging operation.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, reduce the architecture advances that the phenomenon of blocking up, cutter suction dredger time saving and energy saving, that improve dredging operation labour intensity are inhaled the mud mouth.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of cutter suction dredger is inhaled the architecture advances of mud mouth; Comprise the guard shield that is connected with suction mud mouth pipe of inhaling mud mouth pipe, the main shaft outside being installed; It is characterized in that: the said suction mud mouth outside is provided with the arc guardrail; One end of said arc guardrail is welded on the guard shield outer wall, and the other end of arc guardrail is welded on the suction mud mouth pipe outer wall of inhaling the Ni Kou lower edge.
The utility model can also adopt following technical measures:
Said arc guardrail comprises the tree root profile barrier, and said profile barrier is welded on respectively to be inhaled on mud mouth pipe and the guard shield outer wall, is welded with a horizontal guardrail that improves profile barrier intensity between the said profile barrier at least.
Said profile barrier is provided with five.
Said horizontal guardrail is provided with one.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; Promptly be welded with the arc guardrail at suction mud mouth place; This arc guardrail is not influencing under the suction mud mouth flow situation basically; Efficiently solve the problem of cleaning, this kind structure reduces stifled pump situation greatly, solves the pump problem that wastes time and energy of drawing; Reduction is to the maintaining time of self; The situation of blocking up is easy to advantages such as processing.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the lateral view of Fig. 1.
Among the figure: 1, inhale mud mouth pipe; 2, main shaft; 3, guard shield; 4, arc guardrail; 4-1, profile barrier; 4-2, horizontal guardrail; 5, inhale the mud mouth.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1 and Fig. 2; A kind of cutter suction dredger is inhaled the architecture advances of mud mouth; Comprise the guard shield 3 that is connected with suction mud mouth pipe 1 of inhaling mud mouth pipe 1, main shaft 2 outsides being installed; Said suction mud mouth 1 outside is provided with arc guardrail 4, and an end of said arc guardrail 4 is welded on guard shield 3 outer walls, and the other end of arc guardrail 4 is welded on the suction mud mouth of inhaling mud mouth 5 lower edges and manages on 1 outer wall.
In the said structure; Said arc guardrail comprises tree root profile barrier 4-1; Five profile barriers are adopted in this enforcement; Said profile barrier is welded on respectively to be inhaled on mud mouth pipe and the guard shield outer wall, is welded with a horizontal guardrail 4-2 who improves profile barrier intensity between the said profile barrier 4-1 at least, adopts a horizontal guardrail in this enforcement.
The said structure remodeling method, φ 40mm round steel, it is curved in advance round steel to be done camber, and original grid is cut off; Measure and inhale the Ni Kou long 1600mm in centre position, for stoping stifled pump, so with 5 above-mentioned arc guardrails, fillet welding in the vertical position is connected to inhales mud mouth place; Every spacing is not more than 295mm, and this distance is mainly confirmed according to the foreign material maximum outside diameter, 2 visual actual growing of ragged edge; Be welded in up and down respectively and inhale lower edge on the mud mouth, last at the middle part of each root round steel, the welding profile barrier is strengthened its intensity.
Result of use:
Result of use is remarkable after transforming, and has stopped stifled pump situation, and the post processing of blocking up is got up also more convenient, and when situation was light, back pressure can solve, also cope well when serious, and tiltedly going out portion from grid can drop.
The benefit estimation:
Can guarantee continuous construction after the transformation, reduce the number of times of blocking up, before transforming relatively, every day, average energy was practiced thrift 2 hours.Press per hour 2500 sides, the 2500*2=5000 side of dredging every day more, every side is by 18 yuan of calculating, and to create the output value 18*5000=90000 every day first more, pressed calculating in 30 days in every month, and 90000*30=2700000 are first for many creation in every year output value
The above is merely the preferable example of executing of the utility model, is not the practical range that is used for limiting the utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all fall into the technical scope of the utility model.
