Abstract
The utility model discloses a suspending device for a thrust vectoring nozzle of an engine. The suspending device comprises four suspension brackets, a suspension ring, three suspension straps, a powerful ring, suspension strap shackles and connecting shackles, wherein one end of each suspension strap is connected with the powerful ring through the suspension strap shackle; the other end of each suspension strap is fixedly connected with three suspension ring screws which are uniformly distributed on the upper end surface of the suspension ring through three connecting shackles; the four suspension brackets are distributed on the lower end surface of the suspension ring and are fixedly connected with the suspension ring through a pressing plate; and the positions of the suspension brackets, which are arranged on the lower end surface of the suspension ring, correspond to suspension points of the suspended thrust vectoring nozzle of the engine. The levelness of each suspension point is adjusted by a gasket. Each suspension bracket consists of two plates which are mutually perpendicular and fixed; a connecting hole is formed in the upper end of the vertical plate of the suspension bracket; and a through hole is formed in the end socket of the horizontal plate of the suspension bracket. The suspending device disclosed by the utility model has the advantages of simple and compact structure, safety in use, convenience in maintenance, lower manufacturing cost, effectively-increased assembly efficiency, reduced risk of suspension accidents and high quality of a thrust vectoring nozzle assembly.
Description
Technical field
The utility model is to belong to driving engine assembly technique field.It specifically is the hanging apparatus of vector spray assembly in the total process of assembling of driving engine.
Background technology
This assembly is the outer part that supplies, and does not have corresponding hanging apparatus; When lifting this assembly at present, can only adopt two suspender belts simply to lift by crane, but because vector spray assembly weight is bigger, and the suspension centre diameter is littler than assembly flap diameter, assembly flap distortion when causing lifting, total quality can't guarantee; And the assembly center of gravity is higher than hoisting point position, and lifting process shakiness causes the assembly upset easily, mainly leans on people's hand shift, has many potential safety hazards.
Summary of the invention
Cause assembly upset easily, mainly lean on people's hand shift and have the deficiency of many potential safety hazards for overcoming the lifting process shakiness that exists in the prior art, the present invention proposes a kind of driving engine vector spray hanging apparatus.
The present invention includes four suspension brackets, suspension ring, three suspender belts, powerful ring and suspender belt shackle and joining shackles; One end of each suspender belt all is connected with powerful ring through the suspender belt shackle; The other end of each suspender belt is captiveed joint with three ringbolts that are distributed on the suspension ring upper surface through three joining shackles respectively; Four suspension brackets are distributed on the suspension ring lower surface, and captive joint with suspension ring through pressing plate; Suspension bracket is corresponding with the suspension centre of the driving engine vector spray that is lifted in the position of suspension ring lower surface.Levelness through each suspension centre of pad adjustment.
Said suspension bracket is made up of two blocks of plates vertical each other and that fix; There is connecting bore the upper end of said suspension bracket diaphragm plate, and there is through hole suspension bracket horizontal plate termination.
Suspension bracket among the present invention is processed L shaped, and two ends are connected with suspension ring with the vector spray assembly respectively, and the former hoisting point position of driving engine vector spray assembly is stretched out, and amplifies the suspension centre diameter, and has raised hoisting point position, reduces this vector spray assembly center of gravity; Simultaneously, the suspension centre height of adjust with shims vector spray assembly in the site assembly makes the sling height level of each suspension bracket consistent.The attachment point of suspension bracket and suspension ring coupling end is according to each suspension bracket position adjustments.
Because the present invention adopts four independent suspension bracket switchings, and is therefore not high to requirement on machining accuracy.Use pad to regulate sling height, when guaranteeing each suspension bracket stress equalization, the point of connection dislocation of having avoided causing, difficult installation etc. because of Mismachining tolerance.An end that connects suspension ring is fixed with displacable platen, does not need other processing mounting holes, and technology is simple, and is flexible for installation.Suspension ring adopt annular element, have both satisfied the needs of driving engine vector spray lifting point, satisfy under the situation of requirement of strength in assurance again, have reduced the weight of hanging apparatus self as far as possible.Unit design of the present invention is simple in structure, compact, and is safe in utilization, easy to maintenance, and manufacturing cost is lower, and effective raising efficiency of assembling reduces the lifting accident risk, has guaranteed the quality of vector spray assembly.

The specific embodiment
Present embodiment is a kind of driving engine vector spray hanging apparatus, comprises suspension bracket 3, suspension ring 5, suspender belt 9 and powerful ring.Suspender belt 9 has three, and an end of each suspender belt 9 all is connected with powerful ring 8 through suspender belt shackle 7; The other end of each suspender belt 9 is captiveed joint with three ringbolts 10 that are distributed on the suspension ring upper surface through three joining shackles 11 respectively.Four suspension brackets 3 are distributed on the suspension ring lower surface, and captive joint with suspension ring through pressing plate 6.Suspension bracket 3 in the distribution of suspension ring lower surface with the weight that can rationally share the driving engine vector spray and corresponding with the suspension centre of the driving engine vector spray that is lifted.
The diameter of suspension ring 5 must make the position that is fixed on these suspension ring 5 over slings 3 corresponding with the suspension centre of the driving engine vector spray that is lifted.
During use, the horizontal plate of suspension bracket 3 is captiveed joint with the attachment lug at each suspension centre place of driving engine vector spray respectively, in the connection, should avoid the flap of vector spray assembly top; The diaphragm plate end of suspension bracket 3 is fixed on the suspension ring 5 with pressing plate 6 and bolt, nut.Ringbolt 10 is installed in the position near pressing plate, in case suspension ring 5 are out of shape because of stressed.After installing, ringbolt spot welding is fixed.During lifting, whether inspection vector spray assembly level, regulates the ceiling height at each suspension centre place on these assemblies with pad 2, the sling height of each suspension bracket is consistent, and fixes with bolt 1 and nut, when guaranteeing that the vector spray assembly lifts by crane level, stablize.
