Description
Technical field
The utility model relates to a kind of cutter suntion dredger, specifically a kind of cutter suntion dredger underwater dredge pump drive unit.
Background technology
Underwater dredge pump is the visual plant of cutter suntion dredger, and its type of drive directly affects normal operation and the production efficiency of whole ship.At present, the type of drive of underwater dredge pump all adopts long shaft transmission, and namely motor, reduction box are all located at the tail end of reamer frame, drives underwater dredge pump by long pass moving axis, is also provided with middle bearing bracket in the middle of long pass moving axis.One be whole drive unit in running, be difficult to avoid, because the secular distortion of reamer frame produces abnormal vibrations, cause drive unit easily to break down, directly affect production efficiency, and troubleshooting difficulty is large, consuming time many.Two is that installation difficulty is large, and installation accuracy is difficult to ensure card, and cost is high.
Summary of the invention
The purpose of this utility model be to provide a kind ofly to operate steadily, cutter suntion dredger underwater dredge pump drive unit easy to maintenance.
The utility model adopts following technical scheme to realize its goal of the invention, a kind of cutter suntion dredger underwater dredge pump drive unit, it comprises the underwater dredge pump be arranged on reamer frame, reamer frame is provided with stuffing box, motor is provided with in stuffing box, described motor is connected with the underwater dredge pump outside stuffing box by reducing gear, is provided with watertight mechanism between stuffing box and underwater dredge pump.
Reducing gear described in the utility model comprises reduction box, yielding coupling, and motor is connected with reduction box by the first yielding coupling, and reduction box is connected with underwater dredge pump by the second yielding coupling.
For anti-sealing enters stuffing box, watertight mechanism described in the utility model is fixed watertight mechanism, it comprises the sealing drum be arranged on stuffing box casing, described sealing drum is arranged on stuffing box casing by base plate, seal receptacle, sealing ring, pressing plate, and the bearing housing cover plate of underwater dredge pump is arranged on sealing drum.
Owing to adopting technique scheme, the utility model achieves goal of the invention preferably, and its structure is simple, compact, eliminate the conventional long shaft transmission adopted, greatly reduce fault rate, reliable operation, improve the production efficiency of dredge boat, and safeguard simple and convenient, save cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the structural representation of the utility model watertight mechanism.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the motor 3 of underwater dredge pump drive unit, reduction box 5 are all located at the tail end of reamer frame 1, drive underwater dredge pump 8 by long pass moving axis 6, are also provided with middle bearing bracket 9 in the middle of long pass moving axis 6.Because long pass moving axis 6 is oversize, and reamer frame 1 is constantly producing secular distortion, and its misalignment of axe also constantly increases; Drive unit vibrates and also constantly increases in operation process, thus causes middle bearing bracket 9 easily to break down with reduction box 5 and underwater dredge pump 8, and maintenance difficulty is large.And the processing of long pass moving axis 6 also difficulty complexity.
From Fig. 2, Fig. 3, a kind of cutter suntion dredger underwater dredge pump drive unit, it comprises the underwater dredge pump 8 be arranged on reamer frame 1, reamer frame 1 is provided with stuffing box 2, motor 3 is provided with in stuffing box 2, described motor 3 is connected with the underwater dredge pump 8 outside stuffing box 2 by reducing gear, is provided with watertight mechanism 7 between stuffing box 2 and underwater dredge pump 8.
Reducing gear described in the utility model comprises reduction box 5, yielding coupling 4, and motor 3 is connected with reduction box 5 by the first yielding coupling 4, and reduction box 5 is connected with underwater dredge pump 8 by the second yielding coupling 10.
For anti-sealing enters stuffing box 2, watertight mechanism 7 described in the utility model is fixed watertight mechanism, it comprises the sealing drum 15 be arranged on stuffing box 2 casing, described sealing drum 15 is arranged on stuffing box 2 casing by base plate 11, seal receptacle 12, sealing ring 14, pressing plate 13, and the bearing housing cover plate 16 of underwater dredge pump is arranged on sealing drum 15.The rubber seal of fixed watertight mechanism does not contact with moving component, and sealing station is all fixing, and seal is without wearing and tearing, and sealing performance is reliable.
During the utility model application, in order to reliable operation, reduce costs, stuffing box 2 and reamer frame 1 are made in one; Motor 3 and reduction box 5 pedestal are arranged on the base plate of stuffing box 2, and underwater dredge pump 8 pedestal is arranged on the base plate of reamer frame 1.
During utility model works, be arranged on motor 3 in stuffing box 2 as power source, drive underwater dredge pump 8 to carry out the operation of suction mud through reduction box 5, adopt fixed watertight mechanism between the reduction box 5 in underwater dredge pump 8 and stuffing box 2, anti-sealing enters stuffing box 2.The utility model is connected with yielding coupling with reduction box 5 with between reduction box 5 with underwater dredge pump 8 due to motor 3, substantially reduces axial length, overcomes the deficiency of current type of drive.
