The tilting-preventing rod has the beneficial effects of being simple in structure and being safe and reliable because a friction damper and a buffer are combined into one, and being capable of realizing control of relevant parameters of the friction damper and effectively reducing vibration and rebounding of an arm frame through regulating the hoop for regulating the take-up device.
Description
Technical field
The present invention relates to a kind of buffer structure, particularly relate to a kind of anti-hypsokinesis bar and dynamic compaction machinery.
Background technology
Dynamic compaction machinery is particularly being rammed in process in lifting, and vibration and impact are very large, often causes the very large front and back of jib to be rocked and structural fatigue destruction.Existing dynamic compactor arm frame system realizes vibration damping mainly through arranging the mode such as spring bumper, the anti-back tilting buffer device of cylinder type.Spring anti-hypsokinesis storage power ability, goes all out to alter a great deal after anti-, and only has pooling feature, jib can be caused repeatedly to rock back and forth.Cylinder type damping buffer unit, oil cylinder power is directly proportional to the index of speed, and therefore oil cylinder power changes greatly, and cylinder damping cost is high, and fault is more.
Summary of the invention
For the problems referred to above that existing dynamic compaction machinery exists, now provide one be intended to reduce anti-after to go all out change, the simple anti-hypsokinesis bar of structure and dynamic compaction machinery.
Concrete technical scheme is as follows:
A kind of anti-hypsokinesis bar, wherein, comprise the stretching structure making the longitudinal extension of described anti-hypsokinesis bar, described stretching structure comprises fixing section, flexible section and regulates described stretching structure to stretch the damping unit of damping, described damping unit and the described fixing section on described anti-hypsokinesis bar and described flexible section intersection are towards described fixing section side or be connected towards the side of described flexible section, opposite side is provided with the position limiting structure limiting described damping unit movement
Described damping unit is formed in order to the cuff adjusting frictional force between described damping material and described anti-hypsokinesis bar primarily of the damping material and being sheathed on described damping material being coated on described anti-hypsokinesis bar circumference.
Preferably, described stretching structure is formed primarily of interior bar and the outer bar be movably set in outside described interior bar.
Preferably, described cuff has multiple, and what multiple cuff was parallel to each other is sheathed on described damping material.
Preferably, described position limiting structure is formed primarily of the baffle plate be connected on described outer bar or interior bar.
Preferably, described damping material is elastic damping material.
A kind of dynamic compaction machinery, comprise jib, upper frame part and A type frame, wherein, also comprise above-mentioned anti-hypsokinesis bar, described anti-hypsokinesis bar one end is connected with described jib, and the other end is connected on the front arm of described upper frame part or described A type frame.
The beneficial effect of technique scheme is:
1, frcition damper and snubber unite two into one, and structure is simple, safe and reliable;
2, by regulating cuff to adjust take-up, the control to frcition damper relevant parameter can be realized, effectively can reduce vibration and the bounce-back of jib.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of a kind of anti-hypsokinesis bar of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described, but not as limiting to the invention.
As shown in Figure 1, the embodiment of a kind of anti-hypsokinesis bar of the present invention, wherein, comprise the stretching structure making the longitudinal extension of anti-hypsokinesis bar 1, stretching structure comprises fixing section, flexible section and regulate stretching structure to stretch the damping unit of damping, damping unit and the fixing section on anti-hypsokinesis bar 1 and flexible section intersection are towards fixing section side or be connected towards the side of flexible section, opposite side is provided with the position limiting structure limiting damping unit movement, damping unit is formed in order to the cuff 3 adjusting frictional force between damping material 2 and anti-hypsokinesis bar 1 primarily of the damping material 2 and being sheathed on damping material 2 being coated on anti-hypsokinesis bar 1 circumference.
The operating principle of technique scheme is operationally, and the hammer ram of dynamic compaction machinery promotes and starts and braking, and when particularly unhook is rammed, jib will produce rocking of fore-and-aft direction.Rock due to jib and rebound, having relative sliding between the fixing section of anti-hypsokinesis bar 1 and flexible section, the frictional force now between damping unit and anti-hypsokinesis bar will consume the energy rocked, and plays damping action.When flexible section is retracted to extreme position, damping unit will play the effect of buffering under the effect of position limiting structure.Simultaneously, the adjustment to frictional force between damping material 2 and anti-hypsokinesis bar 1 can be realized by the elasticity of the quantity and adjustment cuff 3 that adjust cuff 3, can also by changing the material of damping material 2, or adjustment damping material 2 is coated on cross sectional area on anti-hypsokinesis bar 1, length and adjustment and puts the position of cuff 3 to control cushion rigidity.
On technique scheme basis, further, stretching structure can be formed primarily of interior bar 11 and the outer bar 12 be movably set in outside interior bar 11.
On technique scheme basis, further, cuff 3 can arrange multiple, and what multiple cuff 3 was parallel to each other is sheathed on damping material 2.
On technique scheme basis, further, position limiting structure can be formed primarily of the baffle plate 13 be connected on outer bar 12 or interior bar 11.
On technique scheme basis, further, damping material 2 can be elastic damping material.
Also comprise a kind of dynamic compaction machinery in embodiments of the invention, comprise jib, upper frame part and A type frame, wherein, also comprise above-mentioned anti-hypsokinesis bar 1, anti-hypsokinesis bar 1 one end and jib hinged, the other end is articulated with on the front arm of upper frame part or A type frame.
The foregoing is only preferred embodiment of the present invention; not thereby embodiments of the present invention and protection domain is limited; to those skilled in the art; should recognize and all should be included in the scheme that equivalent replacement done by all utilizations manual of the present invention and diagramatic content and apparent change obtain in protection scope of the present invention.
