Abstract
The pile driving hydraulic hammer includes one outer pipe and one ram hammer inside the outer pipe, and features the oil cylinder in the upper end inside the outer pipe, the piston rod inside the outer pipe and with one part inside the oil cylinder and the other part exposed beyond the oil cylinder, the piston in the upper end of the piston rod, the ram hammer connected to the lower end of the piston rod, and the oil cylinder with oil hole in the lower part and connected to the oil feeder. The pile driving hydraulic hammer in the said structure has reduced length, lowered cost and wide application in piling engineering.
Description
Technical field
What the present invention relates to is the pile hammer that a kind of construction project is used, in particular 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.In order to address this problem; the inventor provides a kind of and can thoroughly effectively reduce noise and eliminate waste gas; the pile hammer of protection urban environment; this pile hammer has also been applied for national patent; its patent No. is ZL02158548.2; the technical scheme of this invention is such: " 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; the principal character of its structure is that hydraulic hammer has oil pressure cylinder; oil storage cylinder and piston rod hammer; long cylinder in being provided with in the described piston rod hammer; the oil-out of the oil-in of long cylinder and oil storage cylinder is connected in described; and the cross section of the section ratio oil storage cylinder cylinder body of oil storage cylinder oil-out is little; be equipped with piston in described oil storage cylinder and the oil pressure cylinder; the piston of described oil pressure cylinder and the piston of oil storage cylinder are critical and form interactive with same piston rod; hydraulic oil arrives interior long cylinder from the oil-out of oil storage cylinder with injecting type; thereby promote the motion of piston rod hammer; hydraulic hammer and external hydraulic power source and power supply are used during work, finish whole operations of hydraulic hammer piling." another kind of this invention improves, and is on the cylinder seat of oil storage cylinder foreign minister's cylinder to be set, and the piston rod hammer in interior long cylinder places this foreign minister's cylinder, can be finished the piling operation equally.The pile-driving hydraulic hammer of above-mentioned this structure, adopted the freely falling body principle, in theory, its piston rod hammer is very big to the hitting power of pile crown, but in the use of reality, owing to be subjected to the influence of various external factors, the piston rod hammer has only theoretic 60% to the hitting power of pile crown, for large-scale construction project, its hammer force can't reach actual needs.Therefore, the inventor has invented a kind of hydraulic pile hammer again in order to overcome this defective, this hydraulic pile hammer has also been applied for patent to State Intellectual Property Office, its application number is 200610057249.1, the independent claims of this patent application are to describe like this: a kind of hydraulic pile hammer, include foreign minister's cylinder, hydraulic jack, oil storage cylinder and hammer ram, described hammer ram places in foreign minister's cylinder, be provided with first piston in the described hydraulic jack, in oil storage cylinder, be provided with second piston, described first piston is connected with piston rod with second piston, it is characterized in that described hydraulic jack is located at the top of foreign minister's cylinder, below oil storage cylinder, be provided with the injection oil cylinder, described injection oil cylinder is communicated with oil storage cylinder, and it is little to spray the cross section of section ratio oil storage cylinder of oil cylinder, is full of hydraulic oil in described injection oil cylinder and the cavity that oil storage cylinder is communicated with, be provided with the 3rd piston in the described injection oil cylinder, described the 3rd piston is connected with hammer ram by push rod.Though the pile hammer of this structure has solved the problem of its hammer force,, bring inconvenience for the construction of engineering, and its cost of manufacture is also higher because its entire equipment is oversize.
Summary of the invention
In view of the deficiency that background technology exists, it is shorter relatively that the technical problem to be solved in the present invention provides a kind of length, the hydraulic pile hammer that cost of manufacture is low.
For solving the problems of the technologies described above, the present invention is a kind of piling hydraulic hammer of taking following technical scheme to realize, comprise outer tube, hammer ram, described hammer ram places in the outer tube, the inside, upper end that it is characterized in that described outer tube is provided with oil cylinder, and piston rod is set in outer tube, a described piston rod part places in the oil cylinder, another part exposes to oil cylinder, be provided with piston in the upper end that places the oil cylinder inner piston rod, the described piston-rod lower end that exposes to oil cylinder is connected with hammer ram, and the bottom of described oil cylinder connects fuel delivery device by oilhole.
This structure of the present invention, it is long to have solved in the prior art pile monkey length, a difficult problem of making troubles to construction, because the shortening of its length, the minimizing of manufacturing materials has reduced cost of manufacture accordingly, simultaneously, owing to adopt hydraulic structure, keep original level for tamping force.The hydraulic pile hammer of this structure, its structure is also simpler with respect to prior art, can be widely used in the pile works of building trade.
Description of drawings
Further describe relevant details of the present invention below more in conjunction with the accompanying drawings.
Fig. 1 is a structure chart of the present invention.
The specific embodiment
With reference to accompanying drawing, this piling hydraulic hammer comprises outer tube 6, hammer ram 8 and die head 9, and described hammer ram 8 places in the outer tube 6, be provided with pulley 1 at the top of outer tube 6, die head 9 is arranged on the below of outer tube 6, also is provided with die head seat 10 at the downside of die head 9, is provided with cushion pad 11 at the downside of die head seat 10, below cushion pad 11, connect die head plate 12, pile cover 13 is arranged below outer tube 6, and the setting of pile cover is convenient to aim at and the pile crown of the preformed pile of slinging; The inside, upper end of described outer tube 6 is provided with oil cylinder 2, and piston rod 7 is set in outer tube 6, described piston rod 7 parts place in the oil cylinder 2, another part exposes to oil cylinder 2, be provided with piston 3 in the upper end that places oil cylinder 2 inner piston rods 7, described piston rod 7 lower ends that expose to oil cylinder 2 are connected with hammer ram 8, and the bottom of described oil cylinder 2 connects fuel delivery device by oilhole 4.When this hydraulic hammer work, fuel delivery device is connected oilhole 4, hydraulic oil just is input to the oil cylinder 2 from oilhole 4, after piston 3 in the oil cylinder 2 is subjected to the pressure of hydraulic oil, just pushing away piston 3 rises, the rising of piston 3 drives hammer rams 8 by piston rod 7 and rises, rise to setting height after, fuel delivery device is just with the hydraulic oil oil return in the oil cylinder 2, at this moment, hammer ram 8 just falls with the speed of freely falling body, after hammer ram 8 falls to putting in place, its tamping force is by die head 9, die head seat 10, cushion pad 11, die head plate 12 is transferred on the preformed pile, make preformed pile enter into soil, repeatable operation like this is to reach the purpose of piling.This hydraulic pile hammer by structure also has very big tamping force, and pre-buried preformed pile is a kind of desirable pile driving equipment in construction project.
