Abstract
The utility model provides a bridge stand pivot device for a suction type dredger, which comprises a base, an upper cover, an automatic aligning assembly and a reamer holder revolution shaft. The base fixed to the dredger body is equipped with a revolution shaft installation groove. The upper cover is equipped with a buckling groove matched with the revolution shaft installation groove. The automatic aligning assembly arranged inside the revolution shaft installation groove is fixed by the upper cover. One end of the reamer holder revolution shaft is arranged inside the automatic aligning assembly and the other end of the reamer holder revolution shaft is connected with a reamer holder. By adopting the above technical scheme, the dredger reamer holder is simpler in installation technology and convenient in maintenance. Meanwhile, the bearing status of the reamer holder during the operation of the suction type dredger is improved and the stability of the dredger during operation is also increased. The work efficiency of the dredger and the work ability of a single dredger are also greatly improved.
Description
Technical field
The utility model relates to the underwater dredging technical field, refers in particular to a kind of crane span structure pivot device that is used for the suction type dredging vessel.
Background technology
The suction type dredging vessel is widely used in the improvement and the harbour of inland river, seaway and safeguards that crane span structure is the visual plant of such boats and ships.Because crane span structure is stressed big in the dredging process, power system is complicated, and own wt is heavy, and physical dimension is big, thereby for crane span structure being installed aboard ship reliably, the crane span structure pivot device of being convenient to maintain again is the important topic that the need of such Ship Design construction solve always.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of installation, maintenance that is used for suction type dredging vessel crane span structure pivot device easily is provided.
For achieving the above object, technical scheme provided by the utility model is: a kind of crane span structure pivot device that is used for the suction type dredging vessel, and it includes base, loam cake, automatic aligning assembly, reamer frame gyroaxis, wherein, base is fixed on the hull, and base is provided with the gyroaxis mounting groove; On cover and be provided with the buckling groove that matches with the gyroaxis mounting groove; The automatic aligning component assembling and is fixed by loam cake in the gyroaxis mounting groove, and reamer frame gyroaxis one end is assemblied in the automatic aligning assembly, and the other end is connected with the reamer frame.
Be connected by bolt between described base and the loam cake.
The utility model when needs are installed the reamer frame, is fixed on base on the hull with bolt earlier after having adopted such scheme, in that the automatic aligning assembly is installed on the reamer frame gyroaxis, covers loam cake, uses bolt.After adopting this programme, the mounting process of Cutters for Dredgers frame is simplified, easy to maintenance; Improved simultaneously the force-bearing situation of reamer frame in the suction type dredging vessel course of work again.Increase the stability of boats and ships when work, can improve the work capacity of boats and ships construction operation efficient and boats and ships list ship greatly.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 is a user mode schematic diagram of the present utility model.
Reference numeral: 1-base, 2-loam cake, 3-automatic aligning assembly, 4-reamer frame gyroaxis, 5-bolt, 6-gyroaxis mounting groove, 7-buckling groove, 8-reamer frame.
The specific embodiment
The utility model is described in further detail below in conjunction with institute's drawings attached, preferred embodiment of the present utility model is: the described crane span structure pivot device that is used for the suction type dredging vessel of present embodiment, it is characterized in that: it includes base 1, loam cake 2, automatic aligning assembly 3, reamer frame gyroaxis 4, wherein, base 1 is fixed on the hull, and base 1 is provided with gyroaxis mounting groove 6; Loam cake 2 is provided with the buckling groove 7 that matches with gyroaxis mounting groove 6; Automatic aligning assembly 3 is assemblied in the gyroaxis mounting groove 6, and fastens by loam cake 2, is connected by bolt 5 between base 1 and the loam cake 2.Reamer frame gyroaxis 4 one ends are assemblied in the automatic aligning assembly 3, and the other end is connected with reamer frame 8.When design dredger hull, maximum dredging depth and minimum dredging depth according to this ship calculate the subdivision angle [alpha] of determining that the crane span structure pivot device is split, analyze the reamer frame force-bearing situation of suction type dredging vessel when dredging, determine the structure and the physical dimension of automatic aligning assembly 3, and according to the structure design loam cake 2 of automatic aligning assembly 3.Make pivot device remain best stress, avoided reamer frame 8 to be subjected to additional force.When needs are installed reamer frame 8, with bolt base 1 is fixed on the hull earlier, in that automatic aligning assembly 3 is installed on the reamer frame gyroaxis 4, cover loam cake 2, fixing with bolt 5.After adopting this programme, the mounting process of Cutters for Dredgers frame is simplified, easy to maintenance; Improved simultaneously the force-bearing situation of reamer frame in the suction type dredging vessel course of work again.Increase the stability of boats and ships when work, can improve the work capacity of boats and ships construction operation efficient and boats and ships list ship greatly.
The embodiment of the above is the preferred embodiment of the utility model only, is not to limit practical range of the present utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the present utility model.
