Abstract
A hydraulic pile hammer with an insertion type variable diameter pile casing core comprises a hammer body, a connection flange, an anvil and a hammer casing, wherein the anvil and the hammer casing are connected into a whole through the connection flange and the hammer body; the anvil which is in a free state is arranged between the hammer body and the hammer casing; the hammer casing is fixedly connected with a pile casing core through a fastening part to enable a pile hammer to be smoothly placed on a steel pile and to be contacted with the surface of the anvil; the pile casing core is in a pipe-shaped structure; one end of the pile casing core is provided with a guide ring; and the bottom of the hammer body is provided with a plurality of seats which are used for transportation. The hydraulic pile hammer with the insertion type variable diameter pile casing core has the advantages of achieving safe and rapid detachment and replacement in an operation field according to common variable diameters; achieving rapid utilization in operation and saving large amount of steel materials, capital and engineering costs; and enabling the variable diameter circumferential degrees to be controllable, reducing operating risks, achieving protection for original pipe casing basic materials and improving the field working efficiency.
Description
Technical field
The utility model relates to hydraulic pile hammer, relates in particular to a kind of hydraulic pile hammer that has plug-in type reducing pile protection core.
Background technology
Hydraulic pile hammer is ocean engineering as widely used key equipments in field such as the operation of offshore oil engineering jacket pile foundation, the installation of oceanic winds electrical engineering pile foundation, the operations of bridge spanning the sea pile foundation.It is by the macro-energy transmission piling bar to be squeezed into the seabed desired depth, thereby realizes the fixing of offshore structures.Pile hammer pile protection wherein then is to allow hydraulic pile hammer be positioned over important composition parts on the piling bar.
Existing pile hammer structure comprises: hammer body, shock ring, adpting flange, anvil iron and hammer cover, wherein, hammer body connects as one shock ring, anvil iron and hammer cover by adpting flange, and shock ring is fixed on the hammer body, and anvil iron is in free state in the middle of being placed on hammer body and hammer cover.
Flourish along with offshore oil engineering and wind-power market, marine piling bar diameter is increasing, and specification also becomes big gradually concerning pile protection, because its structure and material are special, price is also often high.
Current, the user of hydraulic pile hammer when purchasing hydraulic pile hammer, can only purchase according to the maximum diameter of pile of demand, and when needs operation during in less diameter piling bar, common way is: at pile protection interior welds gusset, to realize the variation of pile protection internal diameter.This method shortcoming: the one, consumptive material consuming time, each welding needs a large amount of high-quality steel plates and wlding, and these steel can not reuse; The 2nd, long-term back and forth welding causes the pile protection mother metal can not reparation property destruction; The 3rd, to the welding process requirement height, when long-time piling work, there is the gusset risk of distortion, easily pile driving equipment is damaged.
The utility model content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and a kind of hydraulic pile hammer that has plug-in type reducing pile protection core is provided, and it can realize that the industry site safety changes fast according to reducing dimension seriesization commonly used; And can realize repeating operation and use, save a large amount of steel, fund and engineering cost; Simultaneously, can make the reducing circular degree controlled, reduce operating risk; And realized former pile protection mother metal maximum protection has been improved field operation efficient.
The purpose of this utility model is realized by following technical scheme:
A kind of hydraulic pile hammer that has plug-in type reducing pile protection core comprises: hammer body, adpting flange, anvil iron, hammer cover, and wherein, hammer body connects as one anvil iron and hammer cover by adpting flange, and anvil iron is in free state in the middle of being placed on hammer body and hammer cover; It is characterized in that: this hammer cover is fixedlyed connected with a pile protection core by securing member, pile hammer can be placed on the piling bar smoothly, and the face of realization and anvil iron contacts; The pile protection core is tubular structure, and an end of pile protection core is equipped with guide ring.
The bottom of described hammer body is equipped with several bases of transportation.
The beneficial effects of the utility model: the utility model is owing to adopt technique scheme, and it can realize that the industry site safety changes fast according to reducing dimension seriesization commonly used; And can realize repeating operation and use, save a large amount of steel, fund and engineering cost; Simultaneously, can make the reducing circular degree controlled, reduce operating risk; And realized former pile protection mother metal maximum protection has been improved field operation efficient.

Major label description in figure:
1. anvil iron, 2. hammer cover, 3. pile protection core, 4. bolt, 5. piling bar, 6. base, 7. adpting flange, 8. pilot sleeve, 9. guide ring.
The specific embodiment
As Fig. 1, shown in Figure 2, the utility model comprises: hammer body, guide ring 9, adpting flange 7, anvil iron 1, hammer cover 2 and pile protection core 3, wherein, hammer body connects as one anvil iron 1 and hammer cover 2 by adpting flange 7, and anvil iron 1 is in free state in the middle of being placed on hammer body and hammer cover 2; Pile protection core 3 is tubular structure, and an end of pile protection core 3 is equipped with guide ring 9, and pile protection core 3 is fixedlyed connected with hammer cover 2 by securing member, pile hammer can be placed on the piling bar 5 smoothly, and the face of realization and anvil iron 1 contacts.
The bottom of above-mentioned hammer body adopts the bolt mode that several bases 6 of transportation usefulness are installed.
Before the piling work, at first, according to target piling bar diameter and former pile protection diameter, select the pile protection core 3 of suitable reducing size.In general, pile protection core 3 is installed when the pile hammer horizontal level, and guide ring 9 is as installing in the hammer cover 2 that guide end is deep into hammer body, arrives and the hammer of hammer body overlaps 2 link positions up to adpting flange 7, and then realize that by bolt pile protection core 3 and hammer overlap 2 be connected, and finish installation.
Present embodiment: with when 108 inches needs operations of pile hammer first wife be example in 96 inches piling bars of diameter, as shown in Figure 2, replaceable plug-in type reducing pile protection core 3 (that is: its pilot sleeve 8 diameters are 96 inches), by bolt 4 with hammer cover 2 (108 inch diameters) fixedly connected, pile hammer is placed on the piling bar 5 (96 inch diameter) smoothly, and realizes that pilot sleeve 8 contacts with the stable of piling bar.
The utility model guaranteed pile hammer hammer body, anvil iron 1, piling bar 5 the center point-blank, realized effective transmission of pile hammer energy.When needs during in other diameter piling bar operations, only need to change a plug-in type reducing pile protection core 3 and get final product, save time, safe, can repeat.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
