What little wind there was blew me towards the land ; and thus, having found two or three broken oars belonging to the boat, and besides the tools which were in the chest, i found two saws, an axe, and a hammer, and with this cargo i put to sea ; for a mile, or thereabouts, my raft went very well, only that i found it drive a little distant from the place where i had landed before, by which i perceiv d that there was some indraft of the water, and consequently i hop d to find some creek or river there, which i might make use of as a port to get to land with my cargo
至今我還不知自己身處何地，在大陸上呢，還是在小島上，有人煙的地方呢，還是沒有人煙的地方，有野獸呢，還是沒有野獸。離我不到一英里的地方，有一座小山，高高聳立於北面的山丘之上，看來那是一道山脈。我拿了一支鳥槍一支手槍和一角筒火藥，向那座山的山頂走去。 -
Hydraulic pile hammer is one of the pile driving machines that drive prefabricated piles into the ground in the construction of pile foundation such as construction, bridge, dock, etc. with the development of science and technology, the prefabricated pile driving machines evolve from block hammer, steam - hammer, diesel hammer to hydraulic hammer. hydraulic pile hammer is one of ideal prefabricated pile driving machines because it can adjust stress waveform, decrease stress peak value, prolong effectual action when it drives piles. hydraulic pile hammer is used widely and formed series in developed countries now
液壓打樁錘是用於建築、橋梁、碼頭等樁基礎施工中打入預制樁的樁工機械。隨著科學技術的進步，預制樁施工機械由落錘、汽錘、柴油錘，發展到了液壓打樁錘。用液壓打樁錘打樁，可以調整撞擊應力波波形，減小應力峰值，延長有效作用時間，是一種比較理想的預制樁施工機械，目前在發達國家已被廣泛使用，並形成了系列化。 -
Mechanical impact dynamics is used to analyse the production and spread of stress wave when hydraulic pile hammer hammerblows piles, the stress wave influence the course of driving pile. slender hammer that is equal to wave resistance of the pile can bring ideal stress waveform. when the hammer weight is constant, efficiency of driving pile can be increased by means of selecting drive cap and cushion pad of different rigidity to match the hammer according to various geological condition and the pile. the structure and principium of hydraulic system of double - acting hydraulic pile hammer with double cylinders is studied in detail in the paper, the hydraulic system and electric control system of six - ton - double - actin hydraulic pile hammer with double cylinder is designed on the basis of it
本文應用沖擊機械繫統動力學分析打樁過程中錘體與樁撞擊時應力波的產生、傳播以及該波對沉樁過程的影響。認為與樁等波阻的細長狀錘體能夠產生理想的應力波波形；在樁錘重量一定的情況下，可針對不同的地質情況和樁，通過選擇不同剛度的樁帽和樁墊與其匹配來提高打樁效率。本文對雙缸雙作用液壓打樁錘液壓系統的結構和工作原理進行了深入的研究，並在此基礎上設計出六噸雙缸雙作用液壓打樁錘的液壓系統和電控系統。 -
3 transmission, built in the top drive power head, has two speed range ? high and low. it can meet the requirements of both dth hammer drilling and carbide bit drilling
3動力頭設有變速裝置，有高低兩個檔次，以滿足潛孔錘鉆進及硬質合金回轉鉆進方法。 -
After discharge the moment made by heavy hammer and rocker will drive disc close quickly to realize locking air
一旦積灰卸去后，重錘與搖桿產生的力矩使閥板迅速關閉，實現鎖氣。 -
Just as you use a hammer to help you drive a nail into a wall, so you use a computer to help you solve a problem
就像你用錘子往墻上釘釘子一樣，你使用電腦去解決一個問題。
