Embodiment
Do to illustrate in detail to embodiments of the invention below in conjunction with accompanying drawing, but it is not used for limiting the scope of the invention.
As Figure 1-3, the engine installation structure of the present embodiment, comprise high-altitude operation fuel oil and start 1 and scatterer 2 and the hydro-pump 9 that is installed on fuel engines 1 by shaft coupling, above-mentioned installation structure is respectively by multiple damping rubber pad 5-1,5-2 is connected on engine mount pad 6, engine mount pad 6 is connected by the chassis lug of the getting-on platform 3 of rotary pin shaft 4 with high-altitude operation vehicle, it is achieved engine mount pad 6 drives all component on it overall around the rotatable certain angle of turning axle 4. For reducing the consideration controlling difficulty of making an uproar, being provided with oilless bearing between rotary pin shaft 4 and anchor, instead of rolling bearing conventional in prior art, processing and installation are also convenient. Being welded with rubber cushion blocks mount pad 12 in engine mount pad 6 inside bottom, mount pad rubber shock-absorbing cushion block 11 is connected with rubber cushion blocks mount pad 12 by rubber pad joint bolt 10, plays further shock-absorbing function.
Described engine mount pad is a support body including rectangular flute profile, stiffening web it is provided with in groove, side is provided with parallel upper lug and lower lug, upper lug is the extension of plane on engine mount pad, being in same plane with upper plane, lower lug is bigger than upper lug area, and lower lug and stiffening web link into an integrated entity, spill upper lug part at lower lug and it is provided with pin shaft hole one, for engine mount pad 6 being fixedly connected with at working position and getting-on platform 3. In the upper left corner, lug place is installed with rotary pin shaft 4, and the two ends of rotary pin shaft 4 are located in the oilless bearing of bearing pin open holes of getting-on platform 3. The sidewall on the right side of engine mount pad 6 is provided with fixed orifices, when engine mount pad 6 rotates to working position, by standing bolt 14, set screw nut 13 connecting engine mount pad 6 and getting-on platform 3. The chassis lug of described getting-on platform 3 is provided with a pin shaft hole corresponding to the pin shaft hole of described lower lug.
In order to flexibly guide back-out and the screw-in of engine mount pad 6, just mount pad rubber shock-absorbing cushion block 11 place being welded directing plate 15 on the chassis of getting-on platform 3, described directing plate 15 is bent into the bevel phase by 5 �㡫10 �� and planar section is formed. When engine mount pad 6 screws out maintenance position, rubber shock-absorbing cushion block 11 is also transitioned into and contact of incline plane by with directing plate 15 plane contact, but still plays certain supporting role. When engine mount pad 6 is screwed into working position, rubber shock-absorbing cushion block 11 also by with directing plate 15 chamfered transition to plane contact, now damping supporting role is still played on the chassis of directing plate and getting-on platform 3.
When rotating engine support 6, it is welded on the angle that directing plate 15 bending on getting-on platform 3 formed and can effectively guide being contacting and separating of mount pad rubber shock-absorbing cushion block 11 and directing plate 15, after effectively preventing manufacture, assembling error from causing engine rotation out, the problem of dress cannot be returned smoothly, mount pad rubber shock-absorbing cushion block 11 can effectively isolate the vibrations of motor frame 6 with getting-on platform 3 simultaneously, reaches the effect of damping. When engine mount pad 6 rotates to working position, by standing bolt 14, set screw nut 13 connecting engine mount pad 6 and getting-on platform 3, the base plate of getting-on platform 3 be provided with multiple rotation pilot hole and install baseline positioning hole, anti-rotation bearing pin 7 is fixed through engine mount pad 6 and described installation pilot hole, thus ensures that engine and getting-on platform stable connection are reliable. When engine needs maintenance, cleans, safeguards or changes accessory, take off standing bolt 14, set screw nut 13 and anti-rotation bearing pin 7, engine mount pad 6 is rotated to maintenance position, reconnect anti-rotation bearing pin 7 in rotating in pilot hole, it is possible to carry out service work. For ensureing to be welded with anti-mistake on the base plate of getting-on platform 3 turn block 8 when engine mount pad 6 only then damages hydro-pump 9, described multiple rotation pilot hole and anti-mistake turn block 8 taking origin reference location aperture as center of circle radial distribution. Implementation method of the present invention is simple, economical and practical, is convenient to promote.
