摘要： A hydraulic breaking hammer and method of supporting a percussion piston is provided. The breaking hammer includes a percussion device provided with a reciprocating piston. The piston is supported on a frame at its end portions by a first piston bearing element and a second piston bearing element. The second piston bearing element includes a collar sealing element facing towards a working collar of the piston. The piston bearing elements are easily mountable and dismountable separate components.

摘要： An underground base configured for supporting an above-ground static structure that has a pair of plates each having a distal end, a proximal end, and a body portion between the distal end and the proximal end. The pair of plates are connected to each other to define a box section and a pair of flanges extending outwardly from opposing vertices of the box section. The base further has a plurality of brackets each connected to one of the plates at the proximal end, a base plate connected to the plurality of brackets, and an adjustment plate connected to the base plate via one or more adjustment fasteners. The adjustment plate is movable relative to the base plate via the one or more adjustment fasteners to adjust an orientation of the adjustment plate relative to the base plate.

摘要： An adaptive pile driver system for driving a pile at a worksite. The system comprises a pile driver comprising a motor, an electrical power unit, a drill rod with a first end and a second end. The system further comprises a vibrating module, a hammering module, a drilling module, and a rock drilling module. The pile driver is adaptable to the worksite where the pile is to be driven, by connecting one or more of pile driver modules to the drill rod.

摘要： A mechanical hammer that includes a support and an elongated member. The support defines a linear guide track. The elongated member is laterally confined by the support while being movable back and forth along the linear guide track between an extended position extending from the support and a retracted position relatively retracted within the support. A rack and pinion drive assembly is provided to selectively drive the elongated member along the linear guide track.

摘要： An apparatus for driving a pile section having a central opening into the ground includes a mast attachment with roped hydraulic cylinders, a high frequency hydraulic impact hammer connected with the mast, and a drive cap. The mast with roped hydraulic cylinders provides for vertical movement of the high frequency hydraulic impact hammer, and the drive cap connects with the high frequency hydraulic impact hammer and a pile section to transfer the drive force of the hammer to the pile section. When the mast is connected with an excavator and the drive cap is connected with the high frequency hydraulic impact hammer, a pile section is connected with the drive cap lower end and the high frequency hydraulic impact hammer is operated to drive the pile section into the ground.
A system for driving piles into the ground includes an excavator, an apparatus connected with the excavator, and a plurality of base pile sections. The pile sections have an upper end surface containing a central opening which connects with the apparatus prior to driving the pile sections into the ground. The apparatus includes a mast with roped hydraulic cylinders, a high frequency hydraulic impact hammer connected with the mast, and a drive cap. The mast with roped hydraulic cylinders provides for vertical movement of the high frequency hydraulic impact hammer, and the drive cap connects with the high frequency hydraulic impact hammer and a pile section to transfer the drive force of the hammer to the pile section.-

摘要： A method of recognizing obstacles on operation of a vibratory pile driver of a work machine includes monitoring an acceleration signal of the vibratory pile driver during operation of the vibratory pile operator and analyzing the acceleration signal to determine the presence of an obstacle. The acceleration signal may be monitored over a time period which is determined based on an excitation frequency of the vibratory pile driver. The analysis may include comparing negative and positive half-waves of the acceleration signal. Responsive to the analysis indicating an obstacle, a system operator may be alerted, and/or operation of the vibratory pile driver may be adjusted via controller intervention.
