Abstract
A hydraulic material-loading damping device includes a four-linkage mechanism connected to the material-loading rack which is provided with elastic material on the top. A piston rod of a hydraulic cylinder passes through a connecting base and the material-loading rack. Since the impact is substantially transformed to hydraulic system pressure variation, and unloading is performed by a hydraulic system safety device, a protected transmission under the material-loading rack is protected. The hydraulic material-loading damping device has high responsibility and can be widely applied to heavy machinery industry such as metallurgy.
Description
Technical field
The utility model belongs to metallurgical equipment, particularly a kind of hydraulic pressure bearing material damping device.
Background technique
At present, a lot of loading devices are all directly steel billet to be directly lifted on bin.In the time that steel billet weight is larger, larger to the impact of whole bin, the one, easily directly injure bin surface by a crashing object or directly injure conveying means by a crashing object, the 2nd, easily the basis of equipment is produced and impacted, the time has been grown the basis of easy destruction equipment.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of hydraulic pressure bearing material damping device, has effectively born the impact to bin when steel part falls, and extends the working life of whole material rest device.
In order to achieve the above object, the technical solution of the utility model is:
A kind of hydraulic pressure bearing material damping device, comprise four-bar linkage structure, the bottom of the first rocking bar 2 of four-bar linkage structure and the first base 1 are hinged, rolled and contact with material bearing shelf 7 bottoms by the first roller 8 in the top of the first rocking bar 2, rolled and contact with base 5 by the second roller 11 in the bottom of the second rocking bar 4, the top of the second rocking bar 4 and material bearing shelf 7 are hinged, the first rocking bar 2, the middle part of the second rocking bar 4 connects by bearing pin 3, the top of two the first rocking bars 2 links together by connecting base 10, the first rocking bar 2, the second rocking bar 4, bearing pin 3 forms four-bar linkage structure, material bearing shelf 7 tops are provided with elastic material 9, the piston rod of oil hydraulic cylinder 6 and connecting base 10 are hinged, the bottom of oil hydraulic cylinder 6 is connected on the second base 5.
In described quadratic crank mechanism, to be one end hinged for the first rocking bar 2 and the second rocking bar 4, and the other end rolls along trapped orbit.
Described the first rocking bar 2 and connecting base 10 are rigidly connected.
The beneficial effects of the utility model are:
Owing to impacting the variation that is substantially all converted into hydraulic system pressure, by the off-load of hydraulic system safety installations, thus the transmission device of having protected material bearing shelf 7 belows to protect, this device reliability is higher, can be widely used in the metallurgical heavy machinery industry that waits.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
See figures.1.and.2, a kind of hydraulic pressure bearing material damping device, comprise four-bar linkage structure, the bottom of the first rocking bar 2 of four-bar linkage structure and the first base 1 are hinged, rolled and contact with material bearing shelf 7 bottoms by the first roller 8 in the top of the first rocking bar 2, rolled and contact with base 5 by the second roller 11 in the bottom of the second rocking bar 4, the top of the second rocking bar 4 and material bearing shelf 7 are hinged, the first rocking bar 2, the middle part of the second rocking bar 4 connects by bearing pin 3, the top of two the first rocking bars 2 links together by connecting base 10, the first rocking bar 2, the second rocking bar 4, bearing pin 3 forms four-bar linkage structure, material bearing shelf 7 tops are provided with elastic material 9, the piston rod of oil hydraulic cylinder 6 and connecting base 10 are hinged, the bottom of oil hydraulic cylinder 6 is connected on the second base 5, oil hydraulic cylinder 6 drives the first rocking bar 2 to swing along bearing pin 3, the whole quadratic crank mechanism of final drive swings, thereby promoting material bearing shelf 7 rises.
In described quadratic crank mechanism, to be one end hinged for the first rocking bar 2 and the second rocking bar 4, and the other end rolls along trapped orbit.
Described the first rocking bar 2 and connecting base 10 are rigidly connected.
Working principle of the present utility model is:
Oil hydraulic cylinder 6 piston rods stretch out, promote connecting base 10, drive two the first rocking bars 2 to swing along bearing pin 3, due to four rocking bars of quadratic crank mechanism, to be one end hinged, the other end rolls along trapped orbit, therefore material bearing shelf 7 raises gradually under the promotion of quadratic crank mechanism, and the most whole loading device is raised up to certain altitude.
In the time that weight falls, first its impact absorbs sub-fraction by elastic material 9, most of impact is passed to quadratic crank mechanism by material bearing shelf 7 subsequently, finally be passed to oil hydraulic cylinder 6, oppress its piston rod retraction, oil hydraulic cylinder 6 pressure will raise moment, and the pressure of these risings finally carries out off-load by the safety installations of hydraulic system.
