Full-built-in hydraulic tamping hammer with variable length
The invention provides a full-built-in hydraulic tamping hammer with the variable length, and relates to soil squeezing and hole forming construction equipment. The full-built-in hydraulic tamping hammer comprises a hammer body and a power assembly, wherein the hammer body comprises an upper hammer body, an upper limiting piece, a middle hammer body, a lower limiting piece and a lower hammer bodywhich are sequentially connected from top to bottom; the power assembly is arranged in the middle hammer body and comprises a hydraulic cylinder; a cylinder barrel of the hydraulic cylinder is fixed between the upper limiting piece and the lower limiting piece; an upper buffering cushion is arranged between the upper end of the cylinder barrel and the upper limiting piece; a lower buffering cushion is arranged between the lower end of the cylinder barrel and the lower limiting piece; a piston rod of the hydraulic cylinder is arranged downwards and extends out of the lower limiting piece to beconnected with a hammer core; and the hammer body is divided into the upper hammer body, the middle hammer body and the lower hammer body, the buffering cushions are arranged at the upper end and thelower end of the power assembly, the power assembly is arranged in the middle hammer body, and the hammer core reciprocates in the lower hammer body. The middle hammer body, the upper hammer body andthe lower hammer body are connected to form the full-closed hydraulic tamping hammer, and the purposes of reducing vibration and noise caused by too large penetration of the hammer body and improvingthe reliability of a power head are achieved.
长度可变的全内置液压夯击锤，涉及挤土成孔施工设备，包括锤体和动力总成，锤体包括由上至下依次连接的上锤体、上限位件、中锤体、下限位件和下锤体；动力总成设置在中锤体内，动力总成包括液压缸，液压缸的缸筒固定在上限位件与下限位件之间，在缸筒的上端与上限位件之间设置上缓冲垫，在缸筒的下端与下限位件之间设置下缓冲垫；液压缸的活塞杆朝下布置并从下限位件伸出后连接锤芯。将锤体分为上锤体、中锤体、下锤体三个部分，在动力总成的上端及下端设置缓冲垫，并将动力总成内置于中锤体内，锤芯在下锤体中往复运动。中锤体与上下两锤体连接形成全密闭的液压夯击锤，达到减少由于锤体贯入过大导致是震动及噪音，提高动力头可靠性的目的。
