Embodiment Construction

[0045] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0046] In order to better understand the present invention, the structure of the water jet propulsion device is briefly described below.

[0047] figure 1 It is a schematic diagram of the structure of a water jet propulsion device, such asfigure 1 As shown, the water jet propulsion device mainly includes an inlet pipe 1 , an impeller cover 2 , a main shaft 3 , and a guide vane nozzle 4 . The water outlet end 12 of the inlet pipe 1 is connected with one end 21 of the impeller cover 2, the other end 22 of the impeller cover 2 is connected with the water inlet end 41 of the guide vane nozzle 4, and the tail end of the main shaft 3 passes through a water lubricated bearing (not shown in the figure). Out) Rotationally supported in the supp...

Abstract

The invention discloses an assembling deice of a water spraying propelling device and belongs to the technical field of ship power equipment. The assembling device comprises a tool rack, an inflow pipeline supporting tool, a bearing pedestal supporting tool, an inflow pipeline mounting and positioning tool, a main shaft auxiliary supporting tool, a main shaft mounting and positioning tool and an assembling platform. According to the assembling device disclosed by the invention, the tool rack is arranged to support an inflow pipeline and an impeller hood; the inflow pipeline supporting tool isarranged to support the inflow pipeline; the inflow pipeline mounting and positioning tool is arranged to position the inflow pipeline axially and radially so as to reduce the assembling error of theinflow pipeline; the bearing pedestal supporting tool is arranged to support the forecastle end of the main shaft; the main shaft auxiliary supporting tool is arranged to support the forecastle end ofthe main shaft; the main shaft mounting and positioning tool is arranged to position the main shaft radially to reduce deflection of the forecastle end of the main shaft, so that a guide vane nozzleand the forecastle end of the main shaft are mounted conveniently, and the assembling efficiency and the assembling precision of the water spraying propelling device are improved.

Description

technical field [0001] The invention relates to the technical field of ship power equipment, in particular to an assembly device of a water jet propulsion device. Background technique [0002] The water jet propulsion device is a kind of power device for ships and other water transport vehicles. It mainly generates jet water by jetting water from the stern at high speed, and uses the reaction force of jet water to realize the propulsion of the ship, and can change the jet of water jet The direction realizes operations such as forward sailing, reverse sailing, lateral movement, oblique movement or in-situ steering of the ship. [0003] The structure of the water jet propulsion device mainly includes the main shaft, the inlet pipe, the guide vane nozzle, the impeller, the impeller cover, the rudder steering mechanism and the reversing mechanism. The water inlet end of the vane nozzle is connected, and one end of the main shaft is rotatably supported in the support hole on the...
