The working principle of the present embodiment: the mandrel 1 of damper is connect with guide rod before construction, 37 bottom of shell and vibrating impacter
Connection, passes through the firm connection of bolt；It is lifted by crane after the completion of connection, passes through the first vibration-reducing rubber block 7 and the second damping rubber when lifting
The compressive deformation of block 15, Anti-inclining column 18 will play the role of reducing lifting angle；It is powered and works after the completion of lifting, by
In the hard contact that steel ball 11 is dotted line, play the role of eliminating oscillation crosswise；Since geological conditions variation has when work
Vertical fluctuation, the vertical vibration that vertical fluctuation generates are eliminated by the first vibration-reducing rubber block 7 and the second vibration-reducing rubber block 15, the first damping rubber
The material of block 7 and the second vibration-reducing rubber block 15 is the rubber after natural enhancement, passes through the simply independent blob of viscose of die casting, sulfidization molding.
Existing damper is due to being pure rubber damping and anti-torsion when encountering hard formation in construction by the present invention, since colloid is hard
The case where unevenly generating inclined stake, inclination of degree, the first vibration-reducing rubber block 7, the second damping rubber in shock damper of the present invention
Block 15 cooperates Anti-inclining column 18 that can play situations such as preventing inclined stake, running stake, tilt；After construction by vibrating impacter with
Damper fell together, and the first vibration-reducing rubber block 7, the second vibration-reducing rubber block 15 cooperation Anti-inclining column 18 equally play reduction and put at this time
Chamfer angle, and protect damping device 4 and seal member 3；Vibroflotation construction is divided into it is compacted and displacement, no matter which kind of engineering method damper
Working environment it is all very severe, need to prevent water, mud, sand etc. impurity from entering, shock damper of the present invention is provided with everywhere
Sealing, is related to primary seal 25, outside seal 38, lower seals 26, interior hermetic unit 35, wherein primary seal 25, outer
Sealing element 38, lower seals 26 are all to prevent water, sand, mud etc. from entering from top；Interior hermetic unit 35 is for working as vibrating impacter
It is not connected firmly and leans on damper, into after 2 bottom cavity of housing, interior hermetic unit 35 will be played and be prevented the sundries such as water, sand, mud
The effect that the sundries such as water, sand, mud are flow backwards；Especially in vibro replacement pile driving construction, being typically filled with is the blocks such as rubble, stone is bright
Shape object.
To prevent primary seal 25, outside seal 38 to be damaged, shock damper of the present invention can to primary seal 25,
The housing 2 of the outside of outside seal 38 carries out specially treated, improves its wearability；It can also be in primary seal 25, outside seal
The wear-resisting cone cell housing of setting in 38 outsides, the wear-resisting forged molding of cone cell housing, through Overheating Treatment, peripheral solder has wearing layer,
Play effect wear-resisting and that protection primary seal is not damaged.
In conclusion by adopting the above-described technical solution, compared with prior art, the present invention solves in the prior art
The shortcomings that damper: damping effect is unstable, contradictory relation and each power in the prior art is presented in damping effect and service life
Size vibrating impacter, damper be not general；It is changed for these disadvantage the utility model dampers original all by rubber shock-absorbing
The vibration that vibrating impacter produces is divided into two by thinking: eliminating the oscillation crosswise of vibrating impacter by steel ball, passes through molding damping
Blob of viscose eliminates vertical vibration；Since shock damper is combination assembly mode, damping effect is not only good but also stablizes；Existing skill
The damper of art due to the natural rubber of injection be it is whole, when rubber hardness is high, damping effect is bad, but rubber is viscous
Tie firm not inclined stake；Low in rubber hardness is good damping effect, but rubber bound is not firm, de- split of easily coming unglued.And it is of the invention
Damper desalinates effect of the rubber in damper, not only integral shock-absorbing effect is good, but also the service life using the form of combination assembly
It is higher than existing 5 times or so；Damper in the prior art integrally injects rubber, and rubber hardness is fixed, and damping effect is fixed,
Corollary equipment is fixed；And damper of the invention is combination assembly type, oscillation crosswise is eliminated by steel ball, and no matter power is great
Vibration, which can be given, caused by vibrating impacter eliminates, and vibration-reducing rubber block is to play to prevent the axial vibration for being driven and generating.In addition,
Preferably, this invention also solves following technical problems:
1, it is easy to tear rubber when damping is lifted by crane, cause into water into sand etc.；Existing damper considers damping effect, rises
It is bigger to hang angle, is easy to tear rubber when so lifting by crane；And Anti-inclining column is arranged in the present invention in vibration-reducing rubber block, due to
The presence of Anti-inclining column not only without influencing damping effect, but also reduces lifting angle, and on damper of the invention
There is stringent sealing in lower end, provided with sealing everywhere,
Ensure that in work progress will not intake, into sand etc..
2, the damper production technology of the prior art is complicated, and the period is long；The production technology of damper in the prior art is
Steel part, processing, injection rubber are cast, cannot be carried out simultaneously between technique, due to being injected rubber work by the pressure from environmental protection
Sequence will be more and more difficult；And the technique of damper of the invention can carry out simultaneously, while processing accessory, can notify
External coordination producer carries out vibration-reducing rubber block production, so technique simplification, cycle time.
Preferred embodiment of the invention is described in detail in conjunction with attached drawing above, still, the present invention is not limited to above-mentioned embodiment party
Detail in formula can carry out a variety of simple changes to technical solution of the present invention within the scope of the technical concept of the present invention
Type, these simple variants all belong to the scope of protection of the present invention.
It is further to note that specific technical features described in the above specific embodiments, in not lance
In the case where shield, it can be combined in any appropriate way, in order to avoid unnecessary repetition, the various possibility of the present invention
Combination no further explanation will be given.
In addition, various embodiments of the present invention can be combined randomly, as long as it is without prejudice to originally
The thought of invention, it should also be regarded as the disclosure of the present invention.
