Abstract
The utility model relates to a compacting wheel shock absorption structure of an impact compactor, consisting of a flange clutching, an impact wheel shaft, an impact wheel, a hub, a bearing and an impact wheel shaft tube. The utility model is characterized in that a rubber block which has a cushioning effect is arranged between the impact wheel and the hub and the three mentioned above are combined together. The utility model reduces the instantaneous impact for the wheel shaft tube effectively when the impact wheel impacts the ground, improves the force condition of the wheel shaft tube, avoids the fracture phenomenon of the wheel shaft tube and prolongs the non-failure working time of the impact compactor.
Description
(1) technical field
The utility model relates to a kind of impact compactor, particularly relates to a kind of compact wheel shock-damping structure of impact compactor.
(2) background technology
The compact wheel surface of impact compactor is three lobe cam curve formula shapes, drag by tractor during work, the beater wheel barycenter promotes the back and impacts ground rapidly under the cam curved surface effect, play the compacting effect, and its compacting influences the degree of depth and operating speed all is that traditional compacting machine is incomparable.Therefore, it enjoys the very big attention of highway in China construction department.The domestic and international at present impact compactor of producing, no any damping device between its beater wheel and the beater wheel central siphon, when this compacting machine travelled with the speed of 10-15km/h, the impact force that beater wheel impacts ground can reach 300 tons (according to the quality of beater wheel and travel speed and soil properties different and different).So the destructive power of huge impact power impact hub is greatly, and therefore its beater wheel central siphon phenomenon of rupture of impact compactor that uses at present often takes place.The beater wheel central siphon can only be transported workshop back and change in case fracture can't be repaired on-site at all, promptly causes economic loss to influence the duration progress again.
(3) summary of the invention
The purpose of this utility model provides a kind of compact wheel shock-damping structure of impact compactor, and technical problem to be solved is the instantaneous impact that the impact hub produces when effectively alleviating beater wheel and pounding earthward, thereby avoids the fracture of beater wheel central siphon.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
The compact wheel shock-damping structure of impact compactor has flange to be connect dish, impacts wheel shaft, beater wheel, wheel hub, bearing, beater wheel central siphon, its technical scheme is the block rubber that has added cushioning effect between described beater wheel and the wheel hub, and this block rubber, beater wheel, wheel hub three are fixed in one.
In the technique scheme, described block rubber can be for along beater wheel and the equally distributed a plurality of torus sections of wheel hub joint circumference, each pre-buried bolt of each torus section both sides, two bolts of each torus section pass beater wheel and wheel hub joint respectively along the equally distributed bolt connecting hole of its circumference, and lock with nut.
The utility model is owing to added the block rubber of cushioning effect between described beater wheel and the wheel hub, this block rubber, beater wheel, wheel hub three are fixed in one.Like this, it can effectively the alleviate beater wheel impact hub produces when pounding earthward instantaneous impact has improved the stressing conditions of beater wheel central siphon, thereby has avoided the phenomenon of rupture of beater wheel central siphon to take place.The utility model proves that through type approval test fracture no longer appears in its beater wheel central siphon, and the vibrations of traction frame have reduced, and the average fault-free activity duration has prolonged.
(4) description of drawings
Accompanying drawing is a structural representation of the present utility model.
(5) specific embodiment
As shown in drawings, the utlity model has that flange connects dish 1, impacts wheel shaft 2, block rubber 3, wheel hub 4, bearing (rolling bearing) 5, beater wheel central siphon 6 and 6 ', beater wheel 7.Flange connects dish 1, impacts wheel shaft 2, wheel hub 4, bearing 5, beater wheel central siphon 6 and 6 ', the structure of beater wheel 7 is prior art.(being between the bearing support on beater wheel and the beater wheel central siphon) added the block rubber 3 of cushioning effect between beater wheel 7 and the wheel hub 4, and this block rubber 3, beater wheel 7, wheel hub 4 threes are fixed in one.Described block rubber 3 can be for along beater wheel 7 and wheel hub 4 joint circumference equally distributed a plurality of (as 6 or 8) torus section, each pre-buried bolt 8 of each torus section both sides, two bolts 8 of each torus section pass beater wheel 7 and wheel hub 4 joints respectively along the equally distributed bolt connecting hole of its circumference, and with nut locking, and reach the purpose that block rubber 3, beater wheel 7, wheel hub 4 threes is fixed in one.Described block rubber 3 can also be a torus, this torus is evenly distributed with a plurality of (as 6 or 8) bolt connecting hole along its circumference, a plurality of (as 6 or 8) bolt passes beater wheel 7 and wheel hub 4 joints along the bolt connecting hole on equally distributed a plurality of (as 6 or the 8) bolt connecting holes of its circumference and this block rubber, and with nut locking, and reach the purpose that block rubber 3, beater wheel 7, wheel hub 4 threes is fixed in one.
Claims (2)
1, a kind of compact wheel shock-damping structure of impact compactor, having flange connects dish, impacts wheel shaft, beater wheel, wheel hub, bearing, beater wheel central siphon, it is characterized in that having added between described beater wheel (7) and the wheel hub (4) block rubber (3) of cushioning effect, this block rubber (3), beater wheel (7), wheel hub (4) three are fixed in one.
2, the compact wheel shock-damping structure of impact compactor according to claim 1, it is characterized in that described block rubber (3) can be for along beater wheel (7) and the equally distributed a plurality of torus sections of wheel hub (4) joint circumference, each pre-buried bolt (8) of each torus section both sides, two bolts (8) of each torus section pass beater wheel (7) and wheel hub (4) joint respectively along the equally distributed bolt connecting hole of its circumference, and lock with nut.
