Abstract

The invention discloses a bridge pivot structure used for a suction type dredging ship, which comprises a base, an upper cover, an automatic aligning assembly and a reamer rest rotation shaft, wherein the base is fixed on a ship body and is provided with a rotation shaft installing groove; the upper cover is provided with a buckled groove which is matched with the rotation shaft installing groove; the automatic aligning assembly is assembled in the rotation shaft installing groove and is fixed through the upper cover; and one end of the reamer rest rotation shaft is assembled in the automatic aligning assembly, and the other end of the reamer rest rotation shaft is connected with a reamer rest. By adopting the technical scheme, the installing technique of the reamer rest of the dredging ship is simplified, and the maintenance is convenient; and simultaneously the stress condition of the reamer rest during the working of the suction dredging ship is improved. The stability of the ship during the working is improved, and the ship construction operating efficiency and single-ship operating capability are greatly improved.

Description

A kind of bridge pivot structure for suction type dredge ships
Technical field
The present invention relates to the underwater dredging technical field, refer in particular to a kind of bridge pivot structure for suction type dredge ships.
Background technology
Suction type dredge ships is widely used in improvement and the harbour of inland river, seaway and safeguards, crane span structure is the visual plant of such boats and ships.Because crane span structure is stressed large in Dredging Process, power system is complicated, and own wt is heavy, and physical dimension is large, thereby for crane span structure being installed aboard ship reliably, the bridge pivot structure of being convenient to again to maintain is the important topic that the need of such Ship Design construction solve always.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of installation, maintenance for suction type dredge ships bridge pivot structure easily is provided.
For achieving the above object, technical scheme provided by the present invention is: a kind of bridge pivot structure for suction type dredge ships, and it includes base, upper cover, automatic aligning assembly, reamer frame gyroaxis, wherein, base is fixed on 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 upper cover 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 bolted between described base and upper cover.
The present invention when needs are installed the reamer frame, first is fixed on base on hull with bolt after having adopted such scheme, the automatic aligning assembly is arranged on reamer frame gyroaxis, covers upper cover, fixes with bolt.After adopting this programme, the mounting process of Cutters for Dredgers frame is simplified, easy to maintenance; Improved again simultaneously the force-bearing situation of reamer frame in the suction type dredge ships course of work.Increase the stability of boats and ships when work, can greatly improve the work capacity of boats and ships construction operation efficient and boats and ships list ship.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present invention.
Fig. 2 is use view of the present invention.
Reference numeral: 1-base, 2-upper cover, 3-automatic aligning assembly, 4-reamer frame gyroaxis, 5-bolt, 6-gyroaxis mounting groove, 7-buckling groove, 8-reamer frame.
The specific embodiment
The invention will be further described below in conjunction with institute's drawings attached, preferred embodiment of the present invention is: the described bridge pivot structure for suction type dredge ships of the present embodiment, it is characterized in that: it includes base 1, upper cover 2, automatic aligning assembly 3, reamer frame gyroaxis 4, wherein, base 1 is fixed on hull, and base 1 is provided with gyroaxis mounting groove 6; Upper cover 2 is provided with the buckling groove 7 that matches with gyroaxis mounting groove 6; Automatic aligning assembly 3 is assemblied in gyroaxis mounting groove 6, and fastens by upper cover 2, is connected by bolt 5 between base 1 and upper cover 2.Reamer frame gyroaxis 4 one ends are assemblied in automatic aligning assembly 3, and the other end is connected with reamer frame 8.When design dredger hull, the subdivision angle [alpha] of splitting according to maximum dredging depth and the minimum dredging depth calculative determination bridge pivot structure of this ship, analyze the reamer frame force-bearing situation of suction type dredge ships when dredging, determine structure and the physical dimension of automatic aligning assembly 3, and according to the structure design upper cover 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, first with bolt, base 1 is fixed on hull, automatic aligning assembly 3 is arranged on reamer frame gyroaxis 4, cover upper cover 2, fixing with bolt 5.After adopting this programme, the mounting process of Cutters for Dredgers frame is simplified, easy to maintenance; Improved again simultaneously the force-bearing situation of reamer frame in the suction type dredge ships course of work.Increase the stability of boats and ships when work, can greatly improve the work capacity of boats and ships construction operation efficient and boats and ships list ship.
The embodiment of the above only is the present invention's preferred embodiment, is not to limit practical range of the present invention with this, therefore the variation that all shapes according to the present invention, principle are done all should be encompassed in protection scope of the present invention.
