Description
Technical field
The utility model relates to a kind of pile driver, specifically a kind of portable hydraulic flood control pile driver simple in structure, easy to use, safe.
Background technology
China is vast in territory; rivers in length and breadth; with a varied topography; annual precipitation is concentrated, and most areas is subject to the area in more than 100 ten thousand square kilometres, each downstream, korneforos, great river of the threat of flood damage, particularly China; concentrated the industrial or agricultural output value of national population more than half and 70%; these regional ground elevations have much below river flood water level, and by more than 20 ten thousand kilometers of long levee protection safety, Flood Control Problem is very sharp-pointed.The material base having formed since the flood-prevention project system of having built since dependence founding of New and reform and opening-up, has resisted flood again and again and has attacked, and has protected the people's lives and property safety, alleviates to greatest extent the loss that flood causes.Since ancient times, the Yellow River is the most serious Yi Tiao river of China's flood damage, between take off mouthful from B.C. 602 years to 1938 Huayuankou 2540, the time that Lower Reaches of The Yellow River bursts to spread unchecked has 543 years, breach reaches 1593 times, important changing its course 26 times, and having 6 times is Great Trek, cause immeasurable loss to people's lives and properties, also strengthened the flood damage of Haihe River, Huaihe River two large watersheds simultaneously.
In flood control process, traditional bundle is thrown the emergency techniques such as Liu Shizhen, stake railway carriage or compartment, bavin shore protection ,Liu Shilou County and is being brought into play great function as emergent rescuing and protecting, in these reinforcement methods, need the fixedly Liu Zhenhe railway carriage or compartment special bags of willow branches, framed by bamboo, for building dykes of a large amount of timbers (iron stake), visible piling is an indispensable procedure in various reinforcement methods.Different due to emergency flood fighting environment, geological condition, the purposes of timber is also different, has determined diameter and the depth of drive of timber, affects difficulty and the labour intensity of piling.For a long time, piling mode be take oil hammer, hand and is pounded hand spike as main, labour intensity is large, inefficiency, the pile driver manufacturing and designing both at home and abroad is at present mainly used in building pile foundation engineering and bridge engineering, because pile foundation engineering is mostly the long steel sheet pile of ten or twenty rice, steel pipe pile, reinforced concrete pile with stake, so the exciting force tonnage of pile driver is large to tens of tons, little of several tons, and equipment complete machine weight is large, expensive, transportation inconvenient, uses and limited by place.Emergency flood fighting, except blocking up with long timber and steel pipe pile, is generally used medium and small timber, requires pile driver light and handy, portable, and mobility is good, simple to operate.Obviously, large-scale pile driver is not suitable for the requirement of the piling work of speedily carrying out rescue work.Also there is the shortcomings such as mobility is poor, operation inconvenience, safety, poor stability in existing some other flood control, can not meet the requirement of emergency flood fighting piling work with internal combustion engine-type pile driver and vehicle-mounted pile driver.
The backward situation large by this labour intensity of hand spike, production efficiency is low of for a change speedily carrying out rescue work, realization is mechanization piling work in flood-fighting process, need to research and develop little, lightweight, easy to operate, motor-driven strong, the safe and reliable portable piling machine of a kind of volume, succeeding in developing of equipment also will be brought into play significant role in the emergency flood fighting piling work such as bank sloughing are blocked up, rescued and protected to embankment reinforcement, dyke.
Utility model content
Technical assignment of the present utility model is to solve the deficiencies in the prior art, provides a kind of and maintains easily, portable hydraulic flood control pile driver.
The technical solution of the utility model realizes in the following manner, this a kind of portable hydraulic flood control pile driver, comprise power set, by power set, connect the hydraulic oil container of controlling, the hammer body being connected with hydraulic oil container, described hammer body comprises cylinder body, be arranged on the piston of cylinder interior, be arranged on the pricker body of piston nose, on the fluid pressure line between hammer body and hydraulic oil container, be provided with reversal valve, this reversal valve controls by controlling the flow direction of hydraulic oil the reciprocating motion that realizes piston, make piston complete lifting, stroke the impact force that forms impact on pricker body.

As bottom pressure-bearing surface S
2born the hydraulic oil that comes from hydraulic system, reversal valve 5 is when position shown in Fig. 3, and piston moves upward, and now chamber one 3.2.2 is low pressure.
After piston moves upward, switched the hydraulic pilot oil (switching to high pressure conditions from original low-pressure state) of reversal valve 5 right-hand members, the active area that the active area at reversal valve 5 spool two ends is identical from piston is different, the active area of controlling right-hand member is greater than the active area of left end, due to the difference of spool two ends control area, make reversal valve 5 be switched to position shown in Fig. 4.
After piston hits pricker body 6, now piston is returned to operating position, lower end again, and has switched the guide oil (being switched to low-pressure state from high pressure conditions) of reversal valve 5, again gets back to Fig. 3 state, and hydraulic hammer is with this strike that circulates.
Hit in circulation, when piston is moved upward by the hydraulic oil effect of bottom, the nitrogen in compression upper chamber one 3.2.2, nitrogen chamber has absorbed backhaul energy, when piston hits, discharges nitrogen energy downwards, thereby improves hitting power.
Impact energy is one of important performance indexes of hydraulic pressure hammer body, is calculated the minimal impact energy E that show that piling needs by forward part
0=120Nm, in the impact energy formula of calculating hydraulic hammer by formula E=10pq/n
The impact energy of E-hydraulic pressure hammer body, Nm,
