The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are elaborated, but be not used for limiting the scope of the invention.
As Figure 1-3, the engine installation structure of the present embodiment, comprise that high-altitude operation fuel oil starts 1 and radiator 2 and be installed on the Hydraulic Pump 9 on fuel engines 1 by coupler, above-mentioned mounting structure is respectively by multiple yielding rubber pad 5-1,5-2 is connected on driving engine mount pad 6, driving engine mount pad 6 is connected with the chassis lug of the getting-on platform 3 of aerial platform by rotary pin shaft 4, realize 6 drives of driving engine mount pad on it all parts entirety around the rotatable certain angle of S. A. 4.For reducing the make an uproar consideration of difficulty of control, between rotary pin shaft 4 and fixed mount, be provided with oilless metal, substitute antifriction-bearing box conventional in prior art, processing and install also convenient.Be welded with rubber cushion blocks mount pad 12 in driving 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 tie bolt 10, plays further shock-absorbing function.
Described driving engine mount pad is one to include the stake body of rectangular flute profile, in groove, be provided with reinforced rib, side is provided with parallel upper lug and lower lug, upper lug is the extension of plane on driving engine mount pad, in same plane, lower lug is larger than upper lug area with upper plane, and lower lug and reinforced rib link into an integrated entity, spill upper lug part at lower lug and be provided with pin shaft hole, being fixedly connected with at control position and getting-on platform 3 for driving engine mount pad 6.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 metal of bearing pin mounting hole of getting-on platform 3.The sidewall on the right side of driving engine mount pad 6 is provided with fixed orifice, in the time that driving engine mount pad 6 rotates to control position, by bolt of rear end plate 14, captive nut 13 connecting engine mount pads 6 and getting-on platform 3.The chassis lug of described getting-on platform 3 is provided with the corresponding pin shaft hole of pin shaft hole with described lower lug.
In order flexibly to guide back-out and the screw-in of driving engine mount pad 6, on the chassis of getting-on platform 3, just to mount pad rubber shock-absorbing cushion block 11 place's welding directing plates 15, described directing plate 15 is bent into by bevel phase and the planar section of 5 °～10 ° and forms.In the time that driving engine mount pad 6 screws out maintenance position, rubber shock-absorbing cushion block 11 is also by being transitioned into inclined-plane and contacting with directing plate 15 plane contact, but still plays certain supporting role.In the time that driving engine mount pad 6 is screwed into control position, rubber shock-absorbing cushion block 11 also by with directing plate 15 chamfered transition to plane contact, now shock-absorbing support effect is still played on the chassis of directing plate and getting-on platform 3.
In the time of rotary engine seat 6, be welded on contact that angle that 15 bendings of directing plate on getting-on platform 3 form can effectively guide mount pad rubber shock-absorbing cushion block 11 and directing plate 15 and separate, after effectively preventing that manufacture, assembly error from causing that engine rotation out, cannot return smoothly the problem of dress, mount pad rubber shock-absorbing cushion block 11 can effectively be isolated the vibrations of engine bed 6 and getting-on platform 3 simultaneously, reaches the effect of damping.In the time that driving engine mount pad 6 rotates to control position, by bolt of rear end plate 14, captive nut 13 connecting engine mount pads 6 and getting-on platform 3, the base plate of getting-on platform 3 be provided with multiple rotation knock holees and reference for installation knock hole, rotation prevention pin shaft 7 is fixed through driving engine mount pad 6 and described mounting-positioning holes, thereby assurance driving engine and getting-on platform stable connection are reliable.In the time that driving engine needs repairing, cleans, safeguards or changes accessory, take off bolt of rear end plate 14, captive nut 13 and rotation prevention pin shaft 7, driving engine mount pad 6 is rotated to maintenance position, reconnect rotation prevention pin shaft 7 in rotation knock hole, can carry out service work.For guaranteeing only to transfer to damage Hydraulic Pump 9 when driving engine mount pad 6, on the base plate of getting-on platform 3, be welded with anti-mistake and turn block 8, it is center of circle radial distribution take origin reference location aperture that described multiple rotation knock holees and anti-mistake turn block 8.Implementation method of the present invention is simple, economical and practical, is convenient to promote.
