Detailed description of the invention
In Fig. 1-5, a kind of Diesel engine turn-over rack, including main rotary disk 4 and secondary rotary disk 7, it is connected by back timber 5 and bottom girder 6 between main rotary disk 4 with secondary rotary disk 7, bottom girder 6 is provided with to compress the hold down gag 61 of Diesel engine, back timber 5 is provided with to lock the hand wheel locking device 51 of Diesel engine, main rotary disk 4 and secondary rotary disk 7 bottom are provided with supporting device for sluing mechanisms and the driving means driving main rotary disk 4 to rotate, described main rotary disk 4 edge is provided with the first side ring 41 and the second side ring 43, it is provided with the multiple trundles 42 along main rotary disk 4 circle distribution between first side ring 41 and the second side ring 43, as shown in Figure 5；This structure is used to reduce difficulty of processing compared with using large fluted disc.
In described driving means, can the reductor 2 of self-locking be connected with the axle of main support carriers 10 by shaft coupling 3, axle is fixed with travelling gear 101 and is connected, and travelling gear 101 engages cooperation, as shown in Figure 8,9 with trundle 42 composition.Thus structure, forms engaged transmission between main support carriers 10 and main rotary disk 4, coordinate can the reductor 2 of self-locking, even if the discontinuity equalization of main rotary disk 4 and secondary rotary disk 7 does not haves the situation suddenly accelerated or reverse yet, improve safety.Self-locking alleged by this example, refers to that power can be delivered to output shaft from power shaft, and can not be delivered to power shaft from output shaft, such as cycloidal planetary gear speed reducer, worm-gear speed reducer.
The scheme such as Fig. 1 that optimizes, in 10,11, in described supporting device for sluing mechanisms, supporting pair rotary disk 7 for a pair elastic bearing seat 8.Thus structure, can eliminate the impact shock that between motor drag and trundle and travelling gear, transmission produces, and to reduce equipment loss, improves safety.The auxiliary relative with main support carriers 10 supports seat 9 and uses common roller.
The scheme such as Figure 10 that optimizes, in 11, in described elastic bearing seat 8, elastically supported plate 83 is in inverted "U" shaped, bogie wheel 82 for supporting secondary rotary disk 7 is installed in the first turning point 810 of elastically supported plate 83, hinged with base 85 in the second turning point 811 of elastically supported plate 83, horizontal pull bar 87 it is provided with in the lower end of elastically supported plate 83, pull bar 87 one end is hinged with elastically supported plate 83, the other end is connected with adjusting nut 89, so that bogie wheel 82 the most upwards pushes up through base 85 and spring 88.Thus structure, it is ensured that the bogie wheel 82 of elastic bearing seat 8 contacts with secondary rotary disk 7 all the time, and provides buffering.
In Figure 11, described elastically supported plate 83 two ends are additionally provided with adjustable stop screw, are the first stop screw 81 and the second stop screw 86 as shown in Figure 11.Thus structure, can be conveniently adjusted cushion stroke according to vibration state, and further this structure can also provide good non-yielding prop, and i.e. after its cushion stroke, the supporting force that stop screw is subject to is consistent with Impact direction.
The scheme such as Fig. 1 that optimizes, in 3,6, described back timber 5 uses frame structure, hand wheel locking device 51 is positioned at the both sides of back timber 5, and the top-fastening rod 52 of hand wheel locking device 51 is through back timber 5, and the axis of top-fastening rod 52 is parallel near the limit of main rotary disk 4 and secondary rotary disk 7 with back timber 5 two ends.Thus structure, being easy to be respectively adopted multiple hand wheel locking device at diesel-engine body front-back, what the top-fastening rod of such hand wheel locking device bore is axial force all the time, rather than the side-friction force often occurred in prior art, therefore force structure is good, greatly improves the performance of auxiliary clamping device.
Described hand wheel locking device 51 is provided with 6-10 group.This example preferably uses 8 groups.
In the scheme such as Fig. 7 optimized, described bottom girder 6 is additionally provided with the guide plate 62 for positioning Diesel engine and locating piece.Thus structure, provides for lifting diesel-engine body and guides and location, so that it is guaranteed that diesel-engine body can be lifted on the bottom girder of roll-over table fast and accurately.
Described hold down gag 61 is 16-20 group.This example preferably uses 18 groups.
In the scheme 9,11 optimized, the bearing in supporting device for sluing mechanisms uses sliding bearing.Bearing in main support carriers 10 uses sliding bearing.Owing to the rotating speed of whole device is the highest, therefore use sliding bearing to be sufficient for the needs of lubrication, and use the precision of sliding bearing higher, be also beneficial to reduce vibration.
