Abstract
The utility model provides a combined hammer head of a pile hammer, and relates to the field of building construction machines. The combined hammer head comprises a main hammer head and a secondary hammer head, wherein the secondary hammer head is stacked on the main hammer head, a first vibration-absorbing elastic element is arranged between the main hammer head and the secondary hammer head, and the main hammer head and the secondary hammer head are integrally connected by an elastic connection assembly. The combined hammer head disclosed by the utility model has the advantages that without changing the hammering energy, the maximum hammering force is effectively controlled, the hammering bounce is reduced, the hammering time is prolonged, the piling depth is increased, and a concrete prefabricated pile head can be effectively protected.
Description
Technical field
The utility model relates to the construction machine field, is specially a kind of pile hammer combination tup.
Background technology
Along with the high stratification of urban architecture, the pile foundation load bearing requirements is more and more higher, and the pile foundation degree of depth is more and more darker, and preformed pile is longer, and the pile sinking blow energy requires higher.The hitting power that concrete prefabricated pile head bears is directly proportional to length and the quality of stake, to the blow energy of pile sinking, be directly proportional, and the limit hitting power of its carrying of concrete precast pile is directly proportional to the section area of stake, relevant with the compressive strength of its material.Play dark stake and can not break pile crown again, just need large blow energy, can not surpass again the ultimate bearing capacity hitting power of concrete precast pile, and traditional pile hammer hitting power often is directly proportional to blow energy, plays dark stake and often is difficult to adapt to.
The utility model content
The purpose of this utility model is to provide a kind ofly can effectively control maximum hitting power, reduces and hits bounce-back, extends the hammering time, improves the pile penetration of piling, can effectively protect the pile hammer combination tup of concrete prefabricated pile head.
The technical scheme that realizes above-mentioned purpose is: a kind of pile hammer combination tup, it is characterized in that: comprise main ram head and secondary tup, secondary tup overlays on the main ram head, between main ram head and secondary tup, be provided with the first absorbing flexible member, by elastic connecting component, connect into an integral body between main ram head and secondary tup.
Optimally, described secondary tup is formed by stacking from top to bottom successively by least one tup.
Preferably, between the tup of described secondary tup, can optionally be provided with as required the second absorbing flexible member.
Preferably, between the adjacent tup of described secondary tup, be respectively arranged with the second absorbing flexible member.
Guiding, the type of drive of the utility model pile hammer combination tup and the whole tup of former pile hammer are just the same, during piling, the combination tup is under deadweight and power drive effect, the savings energy, hit the contact pile cover, during strike, the main ram head acts directly on pile cover, realizes first strike, secondary tup acts on the main ram head by the absorbing flexible member, due to the effect of absorbing flexible member, the strike of secondary tup lags behind, and realizes additional strike for the second time.The more, hitting power is longer action time for the more additional cycle of secondary tup quantity of combination tup.
The combinations thereof tup, can reduce and hit bounce-back guaranteeing effectively to control maximum hitting power on the basis that blow energy is constant, extends the hammering time, improves the pile penetration of piling, can effectively protect concrete prefabricated pile head.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises main ram head 1 and secondary tup 2, secondary tup 2 overlays on main ram head 1, between main ram head 1 and secondary tup 2, is provided with the first absorbing flexible member 3, by elastic connecting component 4, connects into an integral body between main ram head 1 and secondary tup 2.
Secondary tup 2 is formed by stacking by least two tups 5,6, between tup 5,6, is provided with the second absorbing flexible member 7.
Claims (4)
