The principle of work of the invention is:
(1) installation car
1. hydraulic efficiency pressure system and lifting mechanism control dismounting platform are realized lifting or the decline of Z-direction., hydraulic efficiency pressure system rises guide rail beam by pressurized strut or declines, and then dismounting platform is promoted or decline; The shutoff valve of hydraulic efficiency pressure system is by distributing valve and manual pump while or control separately pressurized strut, can meet like this: when controlling simultaneously, guide rail beam is promoted simultaneously or drop to sustained height; In the time of independent control, make the both sides height difference of guide rail beam, there is certain degree of dip.2. transverse moving mechanism control dismounting platform is realized the parallel motion of Y direction and the rotation of vertical direction.; stir adjusting screw I (134); drive arc support (141) with respect to aircraft sway by locating dowel pin I (135); stir adjusting screw II (136); drive the rotation of arc support (141) at the arcuate structure of beam both sides by roller (137); realize the rotation of arc support, and then drive two guide rail beams to there is certain diff-H.3. dismounting platform is realized the movement of directions X by straight skidding guide rail., balladeur train is sent into driving engine in Huo Cong cabin, cabin and is taken out by straight skidding guide rail.The invention can realize at X, Y, Z tri-axle six directions and adjust positions, realizes advance and retreat, traversing, lifting and rolling.Driving engine is fixing by bracket (204) and main securing supports (205) on dismounting platform, is convenient to transport.Handwheel drives balladeur train to move by cable wire.Two guide rail beams of installation car are H-girder riveted structure, the tooth bar that guide rail beam is installed above, can make to be fixed on the driving engine on dismounting platform, in without crane equipment handling situation, driving engine be dragged in another driving engine motorcycle from a driving engine motorcycle.
(2) dismounting platform
Dismounting platform is a moveable platform, and platform is connected on two guide rail beams of installation car by four arm revolving gear fit bodies.Platform is a rectangle welded frame, by arm revolving gear fit body, platform is vertically moved on the tooth bar of guide rail beam.Respectively there is a sliding rail mobile platform two side girder inner sides, and the balladeur train on platform is by operation rope barrel handle, and towing cable wire pulls balladeur train to advance and returns.
Main securing supports is fixed on mobile platform midway location, be one and can roll over member, after driving engine is hauled out for the main intersection point of stationary engine.
(3) hydraulic efficiency pressure system
Hydraulic efficiency pressure system is for the transmission of lifting mechanism pressurized strut effect, its principle of work is: the operating fluid of being supplied with from hydraulic reservoir by high-pressure hand pump flows to manipulation distributing valve through oil filter and check valve, in the time that distributing valve handle moves to " liter " position, operating fluid is opened bidirectional hydraulic lock, enters the epitrochoidal chamber of pressurized strut through one-way throttle valve.At this moment, installation vehicle frame can be released and rise to the piston rod of hydraulic actuator.In the time closing manual shutoff valve, each part of hydraulic efficiency pressure system is worked independently by the pump of oneself, and in the time opening, by any one voltage supply in pump group, they are with less speed lifting.By simultaneously or operate separately left and right manual pump, lifting or independent forward and backward lifting when can realizing installation car guide rail beam, wherein manual shutoff valve can make hydraulic lock work make winding machine fine setting lifting.
