Abstract
The utility model discloses a cushioning device which is arranged on the shocking rammer, aiming to reduce the vibration and the noise, and comprises a cushioning piece (11), a fender (12), etc. The fender (12) is covered in a direct rammer face of the cushioning piece (11). The utility model is arranged between a hammer ram (21) and a tamping plate (22), after falling, the hammer ram (21) first contacts the fender (12), and then compresses the cushioning piece (11) through the fender (12), until the hammer ram (21) is contacted with the tamping plate (22), the work surface of the tamping plate (22) bears a rammer force with the utility model together. So the utility model has the advantages of simple structure, reducing vibration and noise, long service time, etc, providing a novel shocking rammer cushioning device.
Description
One. affiliated field
The utility model is a kind of being installed on the battering ram, reduces the buffer of vibration and noise.
Two. background technology:
At present, the heavy battering ram of domestic use is provided with tamping plate mostly under hammer ram, and hammer ram is rammed tamping plate, rams ground by tamping plate, in case material, stone splashes and hurt sb.'s feelings and airborne dust.The hammer ram that has is directly rammed tamping plate, hammer ram contact tamping plate moment formation collision, and vibration is big, noise is big, securing member is easily loosening; What have is provided with one or pool of buffer device between hammer ram and tamping plate, hammer ram is rammed buffer, and buffer will be rammed energy and be passed to tamping plate, reduce vibration and noise, but that buffer damages is frequent, needs often to change.
Three. summary of the invention
In order to overcome above-mentioned shortcoming, the purpose of this utility model provides a kind of simple in structure, battering ram buffer of reducing vibration and noise, long service life.
Design scheme of the present utility model is: the utility model has designed a kind of battering ram buffer, is made up of bolster, backplate etc.Bolster is elastic part or the composite member that rubber or elastomeric material are made, backplate is metalwork or high impact material product, backplate covers directly ramming on the face of bolster, promptly when the utility model is installed on the tamping plate, backplate covers on the upper side that bolster and hammer ram ram, when the utility model was installed on the hammer ram, backplate covered on the downside that bolster and tamping plate ram, and bolster and backplate can be made into one.The utility model is placed between hammer ram and the tamping plate, and (surface that is in contact with one another when work plane refers to ram can be plane, sphere etc. for tamping plate or hammer ram work plane, establish installing hole down together), the utility model is contained in the hole, backplate outwardly, a part of the present utility model exceeds work plane.
During work, at first contact backplate after hammer ram falls, compress bolster, and transmit energy earthward by the utility model and tamping plate; Hammer ram continues to fall and the distilled edition utility model, contacts with the tamping plate work plane until the hammer ram work plane, and tamping plate work plane and the utility model transmit energy jointly earthward by the tamping plate bottom.
Though first wink of contact tamping plate still is a metal bump after the distilled edition utility model of hammer ram whereabouts, owing to cushioning effect of the present utility model and by the cushioning effect of compacting of subsoil face, impact force significantly reduces, and has reduced vibration and noise; Thereafter continued to sink by compacting of subsoil face, hammer ram, tamping plate move in the same way, and the utility model and tamping plate work plane bear tamping force jointly, can reduce vibration and noise, and it is stressed to reduce the utility model again, has prolonged application life.Because hammer ram only contacts with shock-resistant backplate of the present utility model, bolster is not fragile.
Therefore the utlity model has simple in structure, reduce characteristics such as vibration and noise, long service life.
Four. description of drawings
Accompanying drawing is the schematic diagram that the utility model and the utility model are loaded on tamping plate.
Five. specific embodiments of the present utility model
Accompanying drawing is the utility model and the utility model embodiment when being loaded in the tamping plate hole, and by accompanying drawing as seen, the utility model is made up of bolster (11), backplate (12) etc.
Bolster 11 is elastic part or the composite member that rubber or other elastomeric material are made, and backplate 12 is metalwork or other high impact material (as polytetrafluoroethylene (PTFE)) product, and backplate 12 covers on the bolster 11, and bolster 11 and backplate 12 can be made into one.The utility model is placed between hammer ram 21 and the tamping plate 22, establish installing hole on tamping plate 22 or hammer ram 21 work planes, this routine installing hole is located on the work plane of combined type tamping plate 22, the utility model is contained in the installing hole of combined type tamping plate 22, backplate 12 covers the upper side of bolster 11, and a part of the present utility model exceeds tamping plate 12 work planes.
During work, at first contact backplate 12 after hammer ram 21 falls, transmit energy earthward then by backplate 12 compression bolsters 11, and by the utility model and tamping plate 22; Hammer ram 21 continues to fall and the distilled edition utility model, contacts with tamping plate 22 work planes until hammer ram 21 work planes, and tamping plate 22 work planes and the utility model transmit energy jointly earthward by tamping plate 22 bottoms.
Though 22 first winks of contact tamping plate still are metal bump after the hammer ram 21 whereabouts distilled edition utility models, owing to cushioning effect of the present utility model and by the cushioning effect of compacting of subsoil face, impact force significantly reduces, and has reduced vibration and noise; Thereafter continued to sink by compacting of subsoil face, hammer ram 21, tamping plate 22 move in the same way, and the utility model and tamping plate 21 work planes bear tamping force jointly, can reduce vibration and noise, and it is stressed to reduce the utility model again, has prolonged application life.Because hammer ram 21 only contacts with shock-resistant backplate 12 of the present utility model, bolster 11 is not fragile.
Equally, the utility model also can be installed on the hammer ram 21, be contained on the hammer ram 21 o'clock, hammer ram 21 is provided with installing hole, the utility model is contained in the installing hole of hammer ram 21, and then at the downside of bolster 11, backplate 12 contacts with tamping plate 22 earlier backplate 12 during work, by backplate 12 compression bolsters 11, also can have effect same then.
Therefore the utlity model has simple in structure, reduce vibration and noise, long service life Etc. characteristics.
