What is the working principle of a pile driver?
Hammer piling machinePile hammer comprises a hammer head and a hammer base, with steam or compressed air as a driving force, a single action and double action two hammer hammer. Single acting piston or cylinder as the hammer to hammer, steam driven hammer up, then let the hammer seat along the guide rod fall and piling. Double acting steam hammer is increased as the plunger cylinder as the hammer to hammer, steam driven hammer up, then drive the downward impact hammer piling. The reciprocating speed is high and the frequency is high, so that the pile can vibrate when penetrating into the stratum, and the friction resistance can be reduced, and the pile driving effect is good. Differential two-way unequal force hammer, the hammer seat light weight, effective impact weight can be relatively stronger and better performance. The hammer into the exhaust valve reversing by manual control, can also be installed in the side with the hammer and hammer lifting flange lever automatic control, impact stroke two ways can adjust the hammer.
A pile machine that uses the impact force to pile into the formation. It consists of a pile hammer, a pile stand and auxiliary equipment. The pile hammer is attached to two parallel vertical guide rods (commonly called Longmen) at the front of the pile support and hoisted with lifting hooks. Pile frame is a steel tower, in the back part is provided with a winch for hoisting pile and the pile hammer, pile in front of the guide frame of two guide rods, used to control the direction of the pile, pile according to the design range accurately penetration formation. The tower and the guide frame can be used to batter pile deflection. The guide frame can also be extended downward along the tower and used to fetch water along the embankment or pier. The pile can move and move. The basic technical parameters of a pile driver are impact weight, impact kinetic energy and impact frequency. According to the motion of the pile hammer power source can be divided into hammer, hammer, diesel hammer, hydraulic hammer etc..Drop hammer pile driverThe pile hammer is a steel heavy block, which is lifted by a hoist with a hook, and is driven by the free falling of the guide frame after decoupling.
