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, relate in particular to a kind of anti-hypsokinesis bar and dynamic compaction machinery.
Background technology
Dynamic compaction machinery is particularly being rammed in the process in lifting, and vibration and impact are very big, often causes the very big front and back of jib to be rocked and structural fatigue destruction.Existing dynamic compaction machinery boom system is mainly realized vibration damping through modes such as spring bumper, the anti-hypsokinesis buffer of cylinder type are set.Spring is prevented hypsokinesis storage power ability, goes all out to alter a great deal after preventing, and has only pooling feature, can cause jib repeatedly to rock back and forth.Cylinder type damping buffering device, oil cylinder power is directly proportional with the index of speed, so the variation of oil cylinder power is greatly, and the cylinder damping cost is high, and fault is more.
Summary of the invention
To the problems referred to above that existing dynamic compaction machinery exists, provide a kind of at present and be intended to reduce go all out to change anti-hypsokinesis bar and dynamic compaction machinery simple in structure after anti-.
Concrete technical scheme is following:
A kind of anti-hypsokinesis bar; Wherein, Comprise the stretching structure that makes the longitudinal extension of said anti-hypsokinesis bar, said stretching structure comprises fixing section, flexible section and the damping unit of regulating the flexible damping of said stretching structure, and said damping unit perhaps is connected towards a side of said flexible section towards said fixedly section one side with said flexible section intersection with said fixedly section on the said anti-hypsokinesis bar; Opposite side is provided with in order to limit the position limiting structure that said damping unit moves
Said damping unit mainly forms in order to the cuff of adjusting frictional force between said damping material and the said anti-hypsokinesis bar by being coated on the circumferential damping material of said anti-hypsokinesis bar and being sheathed on the said damping material.
Preferably, said stretching structure is mainly formed by interior bar and the outer bar that is movably set in outside the said interior bar.
Preferably, said cuff has a plurality of, and what a plurality of cuffs were parallel to each other is sheathed on the said damping material.
Preferably, said position limiting structure is mainly formed by the baffle plate that is connected on said outer bar or the interior bar.
Preferably, said damping material is an elastic damping material.
A kind of dynamic compaction machinery comprises jib, upper frame part and A type frame, wherein, also comprises above-mentioned anti-hypsokinesis bar, and said anti-hypsokinesis bar one end is connected with said jib, and the other end is connected on the front arm of said upper frame part or said A type frame.
The beneficial effect of technique scheme is:
1, frcition damper and snubber unite two into one, and be simple in structure, safe and reliable;
2, transfer take-up through regulating cuff, can realize control, can effectively reduce the vibration and the bounce-back of jib the frcition damper relevant parameter.
Description of drawings
Fig. 1 is the structural representation of the embodiment of a kind of anti-hypsokinesis bar of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further, but not as qualification of the present invention.
As shown in Figure 1; The embodiment of a kind of anti-hypsokinesis bar of the present invention; Wherein, Comprise the stretching structure that makes anti-hypsokinesis bar 1 longitudinal extension, stretching structure comprises fixedly section, flexible section and the damping unit of regulating the flexible damping of stretching structure, and the fixedly section on damping unit and the anti-hypsokinesis bar 1 and flexible section intersection perhaps are connected towards a side of the section that stretches towards fixing section one side; Opposite side is provided with in order to the position limiting structure that moves of restriction damping unit, and damping unit is mainly by being coated on the circumferential damping material 2 of anti-hypsokinesis bar 1 and being sheathed on that the cuff 3 in order to frictional force between adjustment damping material 2 and the anti-hypsokinesis bar 1 forms on the damping material 2.
The operating principle of technique scheme is when work, and the hammer ram of dynamic compaction machinery promotes and starts and braking, particularly breaks off relations when ramming, and jib will produce rocking of fore-and-aft direction.Because jib rocks and rebounds, have relative slip between the fixedly section of anti-hypsokinesis bar 1 and the flexible section, the energy that this moment, damping unit rocked consumption with the frictional force between the anti-hypsokinesis bar, a 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; Can realize adjustment through the quantity of adjustment cuff 3 and the elasticity of adjustment cuff 3 to frictional force between damping material 2 and the anti-hypsokinesis bar 1; Can also be through changing the material of damping material 2, perhaps adjust damping material 2 and be coated on position that cross sectional area, length and adjustment on the anti-hypsokinesis bar 1 put cuff 3 with control buffering rigidity.
On the technique scheme basis, further, stretching structure can mainly be formed by interior bar 11 and the outer bars 12 that are movably set in outside the interior bar 11.
On the technique scheme basis, further, cuff 3 can be provided with a plurality of, and what a plurality of cuffs 3 were parallel to each other is sheathed on the damping material 2.
On the technique scheme basis, further, position limiting structure can mainly be formed by the baffle plate 13 that is connected on outer bar 12 or the interior bar 11.
On the technique scheme basis, further, damping material 2 can be an elastic damping material.
Also comprise a kind of dynamic compaction machinery in the 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 ends and jib are hinged, and the other end is articulated on the front arm of upper frame part or A type frame.
The above is merely preferred embodiment of the present invention; Be not so limit embodiment of the present invention and protection domain; To those skilled in the art; That should recognize that all utilizations manual of the present invention and diagramatic content done is equal to replacement and the resulting scheme of conspicuous variation, all should be included in protection scope of the present invention.
