Abstract

It is a kind of piling work hydraulic pressure hammer. The main character lays on that, the hammer comprises oil chamber, air chamber and piston chamber hammer. The said air chamber is set on the oil chamber seat. The said piston chamber hammer is set in the outer long chamber. The said hydraulic pressure hammer, out-set liquid pressure source or air pressure source and electrical source get combined to use. When it works, because of the corporation of liquid or air pressure and electric system, the liquid spray through the oil chamber mouth from oil chamber, that propel the pistol chamber to go up, according to the freedom dropping theory, the air is pressed in the air chamber that make the pistol chamber hammer to press the pile-head to produce piling.

Description

Pile-driving hydraulic hammer
Technical field
The present invention relates to a kind of improvement invention of construction project mechanical pile hammer, what be specifically related to is the invention of piling hydraulic hammer.
Background technology
In the prior art, the construction of highrise building and soft foundation all must be driven piles, and pile works in the past all adopts the diesel oil jump bit, when capital construction is driven piles, because the noise of diesel oil jump bit and waste gas cause serious environmental to pollute, and are the problems that near resident, machine-operated school and construction team are extremely perplexed always.
Summary of the invention
In view of the problem that known technology exists, purpose of the present invention aims to provide a kind of scientific structure, and is easy and simple to handle, and can thoroughly effectively reduce noise and eliminate waste gas, the pile hammer of protection urban environment, and abate the noise and the key of waste gas is the form of structure that changes pile monkey.The present invention is finished by following mode, pile-driving hydraulic hammer is made it to impact stake in the pile crown upper punch by the interaction of hydraulic jack inner carrier and piston rod, and sound is eliminated in hydraulic hammer inside by the air seal ring on the cylinder with tapering and the piston rod hammer, reach the purpose that reduces noise, the principal character of its structure is that hydraulic hammer includes oil cylinder, cylinder and piston rod hammer, described cylinder is located on the oil cylinder seat, and described piston rod hammer places in foreign minister's cylinder; Be provided with interior long cylinder in the described piston rod hammer, and place in foreign minister's cylinder with the piston rod hammer; Can be provided with piston rod in the long cylinder in described, described piston rod is hammered into shape also can be connected with piston rod and is placed in foreign minister's cylinder; Foreign minister's cylinder and oil cylinder seat and underseal seat are fixedlyed connected with connector and are become a hydraulic hammer integral body in described; The described cylinder that is located on the oil cylinder seat has tapering, and is provided with the air seal ring on the piston rod hammer; The piston of described big small oil tank connects with same piston rod; Hydraulic oil promotes the motion of piston rod hammer from the cylinder ports of oil cylinder with injecting type hydraulic pressure, and hydraulic hammer and external hydraulic power source or pneumatic supply and power supply are used during work, finish whole operations that hydraulic hammer is driven piles.The present invention has proposed to make with the freely falling body principle of hydraulic hammer the lifting hammering pile crown of piston rod hammer for the first time, finishes the purpose of piling, and sound is eliminated in hydraulic hammer inside.The present invention has rational in infrastructure, and is easy to operate, and noise is low, characteristics such as no waste gas, and pollution abatement effectively, the protection urban environment compared with prior art has outstanding substantive distinguishing features and obvious improvement, is the piling machinery equipment of construction project first-selection.
Description of drawings
The present invention has following accompanying drawing:
Fig. 1 is the structure sectional view of the embodiment of the invention one;
Fig. 2 is the structure sectional view of the embodiment of the invention two.
Wherein number 1 among the figure, suspension ring, 9, locating piece, 10, connecting bolt, 13, interior cushion pad, 15, fastening screw nut, 17, check nut, 23, seal, 26, oily joint.
The specific embodiment
Accompanying drawing has been represented structure of the present invention and embodiment, further describe each relevant details and operating principle of embodiment below more in conjunction with the accompanying drawings, in conjunction with Fig. 1, the hydraulic hammer of embodiment one includes oil cylinder, cylinder 11 and piston rod hammer 5, long cylinder 14 in being provided with in the described piston rod hammer 5, described piston rod hammer 5 with interior long cylinder 14 places in foreign minister's cylinder 7, foreign minister's cylinder 14 in described, 7 fixedly connected with oil cylinder seat 21 and underseal seat 25 usefulness connectors and to become a hydraulic hammer integral body, the cylinder 11 that is located on the oil cylinder seat 21 has tapering, this tapering is actually a horn mouth, and on piston rod hammer 5, be provided with air seal ring 12, the piston 24 of oil cylinder 22 is connected with the same piston rod 19 of piston 18 usefulness of oil cylinder 16, the fuel feeding of described oil cylinder 22 is connected with oily joint 28 and external hydraulic power source or pneumatic supply respectively, the upper connecting tube 2 usefulness flanges 3 that the top of hydraulic hammer is provided with guide ring 4 connect, the connecting portion of oil cylinder is respectively equipped with upper press cover 6 and lower cover 20, and all be provided with seal, the hydraulic system that the present invention and complete machine are equipped with at the gland position, each device of baric systerm and electrical system cooperates operation.
In conjunction with Fig. 2, embodiment two is to be provided with piston rod 8 in interior long cylinder 14, and described piston rod hammer 5 connects with piston rod 8 and is placed in foreign minister's cylinder 7, other details with
Embodiment one is identical.
When the present invention works, open starting switch, electromagnetic valve work, the oil cylinder of hydraulic hammer and cylinder are connected with external hydraulic power source or pneumatic supply respectively, machine normally moves, hydraulic power source passes through oily joint 28 to oil cylinder 22 fuel feeding, oil pressure increases, promote to move on the piston 24, piston 24 drives piston rod 19 and drives upper piston 18 simultaneously the hydraulic oil in the oil cylinder 16 is ejected into the interior long cylinder 14 from oil-out, force piston rod hammer 5 upwards to push away, when making piston rod hammer 5 accelerate movement velocity to design height, electromagnetic valve conversion oil pressure source is passed through oily joint 27 to oil cylinder 22 fuel feeding, lower pistons 24 in the oil cylinder 22 are moved downward drive upper piston 18 hydraulic oil of interior long cylinder 14 is withdrawn into rapidly in 16 oil cylinders, piston rod hammer 5 modes with freely falling body are fallen rapidly along axis, when piston rod hammer 5 arrives the horn mouth of cylinder 11, air in the cylinder 11 is compressed, air seal ring on the piston rod hammer 5 is enclosed in noise in the cylinder 11, sound is eliminated in cylinder, when compressed air is increased to when closely being pressed in oil cylinder seat 21 and underseal seat 25 and pile cover on the pile crown, promptly impact piling, so circulation, go round and begin again, promptly finish the piling operation of whole construction project.Because the cross section of oil cylinder 16 is compared with the cross section of interior long cylinder 14, the cross section of long cylinder 14 is much bigger in the section ratio of oil cylinder 16, and when hydraulic oil was mobile from inwardly long cylinders of oil cylinder 16 14, its pressure was very big, so the present invention claims the jetting type liquid hammer again.According to the pile-driving hydraulic hammer of design motif made of the present invention, have scientific and reasonable for structurely, easy to operate, noise is low, is the protection urban environment, the mechanical pile driving equipment that updates in the capital works of polluting that abates the noise.
