Abstract
The utility model discloses a buffer assembling used for diesel fuel pile hammer, which adopts proper buffer assembly to form a upper and a lower vibration reduction through the way that the inner buffer and the outer buffer set are respectively connected to the upper end and the lower end of the connection flange of the cylinder under the diesel oil hammer. The utility model thus has two advantages of that: on one hand, the impact force of the diesel oil hammer produced in operation will be effectively released, and the damage to the piston, pile cap and pile head of the pile to be used under the diesel oil hammer will be reduced. On the other hand, due to the improvement in structure, the buffer replacement frequency and the labor intensity of the constructors to replace the buffer will be decreased, effectively controlling the operation risk for the pile foundation at sea.
Description
Technical field
The utility model relates to a kind of cushion pad combination that is used for diesel pile hammer, especially a kind of cushion pad combination that improves the tubular diesel pile hammer effectiveness in vibration suppression, prolongs its application life.
Background technology
At present and since tubular diesel pile hammer have bigger blow energy, higher efficiency of construction and can batter piling etc. characteristics, extensively apply in the foundation construction operation.In the prior art, in order to alleviate the impact of impact energy that diesel hammer work the time produced to its lower piston, pile cover and pile crown, generally adopt 2 of between diesel hammer lower piston and following cylinder installations semi-circular outside the technical scheme of cushion pad in cushion pad and 1 circle.
Development along with large foundation engineerings such as offshore oil platform, deep water port harbour, bridge spanning the seas needs the bigger tubular diesel pile hammer of blow energy.And along with the increase of diesel hammer blow energy, following shortcoming just appears in the cushion pad of this structure: 1, cushion pad is because of intensity and structure problem, damage easily fracture, directly have influence on the application life of diesel hammer, pile cover and stake itself are also produced to a certain degree destruction; 2, bring very big inconvenience because of fault of construction to constructor transposing, particularly dislike the strict task difficulty that more increased because of environment during operation on the sea.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of cushion pad combination that is used for tubular diesel pile hammer, the impact force that produces in the time of effectively alleviating diesel hammer work, improve diesel hammer application life, reduce the labour intensity that cushion pad is changed frequency and reduced constructor's exchange buffering pad, the risk of diesel pile hammer operation on the sea is effectively controlled.
For solving the problems of the technologies described above, a kind of technical scheme that is used for the cushion pad combination of tubular diesel pile hammer of the utility model is, comprises interior cushion pad, outer cushion pad group and adpting flange, and wherein, the upper surface of described adpting flange is equipped with cushion pad in the annular; Cushion pad group outside being equipped with in the cannelure of the lower surface of adpting flange, described outer cushion pad group is made up of the outer cushion pad of the identical arc-shaped structure of multi-disc.
When the utility model is worked at tubular diesel pile hammer,, prolong the application life of diesel hammer because the damage of the impact energy that upper piston produced to lower piston, pile cover and use pile head alleviated in the effect of the inside and outside cushion pad of adpting flange greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the partial structurtes schematic diagram of pile hammer lower end;
Fig. 3 is the structural representation of 4 outer cushion pad group;
Fig. 4 is the structural representation of 6 outer cushion pad group.
Be labeled as among the figure: 1. upper piston; 2. lower piston; 3. descend cylinder; 4. interior cushion pad; 5. adpting flange; 6. outer cushion pad group; 7. pile cover; 8. stake.
The specific embodiment
As depicted in figs. 1 and 2, the utility model comprises interior cushion pad, outer cushion pad group, adpting flange 5 and following cylinder 3, wherein, the annular vibration damping band together that cushion pad 4 is formed in the upper surface mounting circular ring shape of described adpting flange 5 is equipped with another road circle buffer strip of being made up of the outer cushion pad 6 of some identical arc-shaped structures in the cannelure of the lower surface of adpting flange 5.Adpting flange 5 is fixed on down cylinder 3 bottoms by high-strength bolt.
Be installed in down the interior cushion pad 4 of cylinder 3 adpting flanges 5 upper and lower end faces and the cushion pad combination that outer cushion pad 6 is formed, formed twice ring-type vibration damping band up and down, the impact energy that upper piston is produced in the time of effectively resisting tubular diesel pile hammer work, minimizing has prolonged the application life of tubular diesel pile hammer to the damage of diesel hammer lower piston, pile cover and use pile head.
As shown in Figure 3, outer cushion pad group is made up of the outer cushion pad of 4 arc-shaped structure rubber materials.
As shown in Figure 4, outer cushion pad group is made up of the outer cushion pad of 6 arc-shaped structure rubber materials.
Cushion pad is made by the rubber material of cirque structure in of the present utility model, and outer cushion pad group adopts the rubber material of 4 or 6 arc-shaped structures to form, because the improvement of this cushion pad arc structure, can guarantee to have higher structural strength and shock-resistant ability, prolonged application life, can reduce simultaneously the labour intensity that cushion pad is changed frequency and reduced constructor's exchange buffering pad, the risk of marine pile foundation operation is effectively controlled.
Claims (4)
