    摘要： A battery-powered log splitting machine can include a frame structure, a first hydraulic actuator supported by the frame structure and including a first piston rod assembly movable between extended and retracted positions, a splitter wedge connected to the piston rod assembly, a second hydraulic actuator in fluid communication with the first hydraulic actuator in a series arrangement, a linear electric actuator operably coupled to the first hydraulic actuator, a battery pack for powering the linear electric actuator, and an operator input controlling operation of the linear electric actuator. When the operator input is displaced in a first direction, the electric motor is energized to result in the first piston rod assembly moving towards the extended position. When the operator input is displaced in a second direction, the electric motor is energized to result in the first piston rod assembly moving towards the retracted position.

    摘要： A piston body (11) of an advancing-retracting first piston (10) and a force-multiplying second piston (15) are arranged in series in a vertical direction in a housing (1). Force acting on the second piston (15) due to pressurized oil in a lock chamber (16) is multiplied and converted into multiplied upward force via engaging balls (32) of a force multiplier (30). Then, the multiplied upward force is transmitted to an output rod (12) of the first piston (10). At an intermediate part of a first air detection passage (38) for use in detection formed in the housing (1), a first detection valve (40) is provided. When the engaging balls (32) move inward in a radial direction, the first detection valve (40) is closed.

    摘要： The invention relates to a hydraulic device for driving an actuator to be hydraulically controlled or actuated, comprising a motor arranged in a motor housing, a compensating tank (31) for accommodating hydraulic fluid, and a hydraulic pump, which is arranged in a pump housing and driven by the motor, wherein the hydraulic pump is designed in such a way that the hydraulic pump permits conveyance of hydraulic fluid in two directions, namely in the forward direction and in the backward direction, wherein the hydraulic actuator comprises a drive cylinder, which has a first and a second cylinder chamber and a drive piston (3) arranged therebetween, to which drive piston a drive shaft (2) that can be displaced in the longitudinal direction is attached, wherein the device comprises a loading cylinder for an emergency closing spring (16), in which loading cylinder a loading cylinder chamber (12) and a loading piston (11) that can be coupled to the drive shaft (2) are arranged, wherein the emergency closing spring (16) can be loaded into a loaded or emergency-triggering readiness position by the loading piston (11), wherein the loading cylinder chamber (12) is connected to an outlet of the hydraulic pump in such a way that the loading cylinder chamber (12) can be filled with hydraulic fluid by means of the hydraulic pressure of the hydraulic pump and the loading piston can be transferred into a loading position as the emergency closing spring (16) is compressed and the loading piston can be locked there hydraulically by means of check valves (36, 37), and wherein a controlled seat valve (50) is connected to an inflow/outflow opening of the loading cylinder chamber, by means of which seat valve the emergency closing spring (16) can be transferred from the loaded readiness position into an emergency-triggering opening position, wherein both the hydraulic fluid that is contained in the loading cylinder chamber (12) and holds the emergency closing spring (16) in the readiness position and the hydraulic fluid contained in the first cylinder chamber can be discharged via the controlled seat valve (50).

    摘要： A recirculating gradient power system includes a motion carrier capable of changing its tilt orientation and tilt angle. The central vertical axis of the motion carrier is provided with a rotating shaft. The rotating shaft is pivotally connected with a counterweight. The counterweight is rotationally displaced from a high point of the motion carrier toward a lower point of the motion carrier about the rotating shaft by gravity. At least four power cylinders are evenly arranged at four diagonal corners around the periphery of the central vertical axis of the motion carrier to drive the motion carrier to change the tilt orientation and the tilt angle. A control module is connected with the power cylinders for controlling the operation of the power cylinders which are set in advance when the counterweight is rotationally displaced to a predetermined stroke.
