The hydraulic pile feeding hammer has low noise, no environment pollution, convenient operation, high pile driving efficiency, low cost, simple structure and easy application; the hydraulic pile feeding hammer can work continuously in various soil conditions for a long time. The hydraulic pile feeding hammer is especially suitable for piling in various construction works and can be used on the existing diesel pile driver frame.

Description

Hydraulic hammer-apparatus

The utility model relates to a kind of fluid power beetle-head, belongs to the improvement of pile hammer, is particularly suitable for the piling of all kinds of capital workss, also can use on the frame of existing diesel hammer.

The pile hammer of builing industry use at present, common is diesel hammer, along with the development building of urban construction is high-level, the pile body lengthening, section increases, and this hammer is the needs of incompatibility construction work development more and more.Under existing structure and technical condition, it is very difficult improving impact energy again, and noise is big simultaneously, and contaminated air is serious, can not also not detonate at the weak soil layer by long time continuous working (because of cylinder body generates heat, is difficult for detonating) in the work progress.

The external in recent years hydraulic hammer that occurs has overcome the shortcoming of diesel hammer substantially, but because manufacturing process complexity, cost height, and its application is restricted.

Though noise and air-polluting problem have been liberated in the appearance of auger, can only be suitable for castinplace pile and require very tight (sand bed, cobble, water content are big, and plasticity height etc. are inapplicable) the little trowel used for plastering soil of bearing capacity amount big soil class.

The purpose of this utility model is to provide a kind of defective that can eliminate diesel hammer, hammer body weight saving (about 45%) the hydraulic circuit system production domesticization with external hydraulic hammer uniform impingement energy can obtained again, manufacturing process is simple, the reduction cost, solve the frangible problem of pile crown, and the fluid power beetle-head that can on existing pile frame, use.

The purpose of this utility model realizes by the following technical solutions, the hydraulic circuit system that mainly contains anvil block, tup and control frequency of impact is formed, its anvil portion branch comprises the anvil block housing of composite material, inner chamber 7 is equipped with oily medium, respectively the dress thereon valve piston 5 and the big piston 8 of bottom, control lever 6 passes anvil block housing shoulder and big piston 8 links; Tup partly has main piston 12, its lower end is packed in the groove above the anvil hammer 15, it descends anvil pallet 1 insert, connecting rod 14 is by in it, paying piston 13 installs on it, the snap ring top of paying piston 13 in the main piston 12 of packing into, touching lever 10 upside-down mountings in the top of pile monkey, guide peg 18 by anvil hammer 15 and anvil block housing on corresponding pilot hole, be loaded on the tie-plate between ring-type auxiliary tank 9 and anvil block, for overcoming the decline resistance, hammer into shape between 15 lower surfaces uniformly at anvil block lower shoulder and anvil, four extension springs 4 are housed; The hydraulic circuit system of control frequency of impact has wall Zhou Shangduan that spill port is arranged.The oil cylinder 11 of fuel feed hole and the ring-type auxiliary tank 9 on top are arranged at the bottom, the quick loop of the gravity of its constant fuel feeding, with high pressure rubber hose respectively be loaded on the pile driver platform on pumping plant link to each other.

Described touching lever 10 is to adopt adjustable length plunger-type cylinder.

The utility model compared with prior art has low, the contaminated air not of noise, piling efficient height, easy and simple to handle, the equal impact energy tup of weight is light by 45%, simplified manufacturing process, reduced cost, pile crown is not cracked and the more external similar hammer of its hydraulic system of can long-time continuous working under all kinds of edaphic conditions has been simplified advantage such as 50%, and is simple in structure simultaneously, implement to be beneficial to easily to apply.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the structural representation of anvil block.

Fig. 3 is the structural representation of hydraulic system and tup.

Fig. 4 is the structural representation of touching lever.

Embodiment of the present utility model is described in conjunction with the accompanying drawings, the anvil block housing is to adopt outer glass fiber reinforced plastic, the composite construction of lining steel plate, its inner chamber is full of oily medium, valve piston 5 and big piston 8 are loaded on the top and bottom in its chamber respectively, seal with the polyurethane rubber circle with its wall, anvil block gland 2 is adorned thereon, and control lever 6 links to each other with big piston 8 by the lower shoulder of anvil block housing; The upper end is fixed with connecting rod 14 lower ends of paying piston 13 and passes anvil hammer 15, anvil pallet 1 insert of polyurethane rubber in it down, the lower end of main piston 12 is packed in above the anvil hammer 15 in the corresponding grooves, the tops that snap ring is packed into and paid pistons 13 in the main piston 12, and there is spill port in upper end wall week.The oil cylinder 11 of oil supplying hole is arranged at the bottom, be loaded on outside it, the touching lever 10 of adjustable length plunger hydraulic, upside-down mounting is in the top of pile monkey, oil seal ring is equipped with in the lower end of oil cylinder 11, and its fuel feed pump 17 that adopts the quick loop of constant fuel feeding gravity and oil return pipe 16 are connected with high pressure rubber hose with pumping plant on being installed in the pile driver platform; Uniform between anvil block and the anvil hammer 15 four extension springs 4 are housed, guide peg 18 is loaded on the auxiliary tank 9 and the mounting disc between the anvil block of upper end by the corresponding pilot hole of anvil hammer 15 and anvil block housing, and hammer body outer cover 19 is loaded on outside it.

When using, realizes the utility model by following program, hydraulic system is started working gear pump with the constant fuel feeding, this moment is owing to pay piston 13 with 3 sealings of the outage on main piston 12 walls, hydraulic oil more than 150 enters inner chamber 20, drive main, paying piston etc. walks to rise, when the top of paying piston 13 and touching lever 10 collisions in a flash, pay the end face that piston 13 whereabouts connecting rods 14 expose anvil hammer 15, outage 3 is opened, the top that oil enters oil cylinder 11 drains into the loop through auxiliary tank 9, oil pressure in the inner chamber 20 is anxious to descend, anvil hammer 15 hurtles down, by anvil pallet 1, valve piston 5 transmits oil supply medium 7 with impact energy, impact energy is changed into static pressure by oily medium 7 again and acts on the pile crown through big piston 8.Owing to when anvil hammer 15 drops to anvil block, again original position is got back on connecting rod 14 tops, pay piston 13 sealing outages 3, next program begins, and the circulation that goes round and begins again is like this gone down, and realizes the purpose of piling.
