    • Embodiments of the present invention pertain to a drop hammer (100) comprising a load (172), an actuator (116) connected to the load (172), and a fluid circuit (132) that is connected to the actuator (116) and is connectable to a fluid source (580), such as a source of hydraulic power. The fluid circuit (132) is operable with differential pressure to displace the load (172) . The fluid circuit (132) includes a slow-release device (503) for releasing differential pressure, thereby slowly displacing the load (172) as a function of flow from the fluid source (580). Embodiments of the present invention also pertain to a drop hammer (100) comprising a frame (106), a selectively actuated rotatable sprocket (122) mounted on the frame (106), a hammer implement (172), and at least one chain (101) engaged by the sprocket (122). The chain (101) includes two-pitch link (102) that includes a catch (150) between two pitched wings (412, 414), the catch (150) being configured for engaging the hammer implement (172), enabling the first chain (101) to displace the hammer implement (172). Other embodiments pertain to a drop hammer (100) that includes a frame (106) and a selectively actuated hammer implement (172) displaceably mounted on the frame (106) . The hammer implement (172) includes a collar (113) surrounding an impact tool (104).

    • An apparatus for generating an impact against a target object comprises a driver reciprocally disposed in a housing. The driver includes a hollow tube having a closed end and a nozzle sealing the other end. A piston is slidably positioned in the tube. Propellant is disposed between the piston and the closed end of the tube and fluid is disposed between the nozzle and the piston. A rupture disc is provided for sealing the nozzle which is adapted to rupture when the pressure in the tube exceeds a predetermined pressure. A striker is also mounted in the housing so that in a retracted position of the striker a head portion is proximate the driver and a portion of a shaft extends outwardly from the housing. The striker member is movable between the retracted position and an extended position. The propellant is ignited so that combustion gases build pressure in the tube between the piston and the closed end of the tube causing the pressure in the tube to exceed the predetermined pressure for rupturing the disc. This causes the piston to move toward the nozzle and fluid to be expelled through the nozzle for moving the driver against the head portion of the striker. The driver transfers energy to the striker for moving the striker to the extended position at high velocity for driving the end of the striker with great force against the target object. Recoil action is cushioned by the fluid exiting the nozzle.
    • 用于产生对目标物体的冲击的装置包括相互设置在壳体中的驱动器。 驱动器包括具有封闭端的中空管和密封另一端的喷嘴。 活塞可滑动地定位在管中。 推进剂设置在活塞和管的封闭端之间,并且流体设置在喷嘴和活塞之间。 提供了一种用于密封喷嘴的破裂盘,当管中的压力超过预定压力时,其适于破裂。 撞击器也安装在壳体中,使得在撞针的缩回位置,头部靠近驱动器,并且轴的一部分从壳体向外延伸。 撞击部件可以在缩回位置和延伸位置之间移动。 推进剂被点燃,使得燃烧气体在活塞和管的封闭端之间的管中产生压力,导致管中的压力超过预定压力以破坏盘。 这使得活塞朝向喷嘴移动并且通过喷嘴被排出的流体,用于使驾驶员抵靠撞针的头部。 驾驶员将能量传递到撞击器,用于以高速度将撞击杆移动到延伸位置,以用力以较大的力将目标物体推向撞击物的末端。 回流动作由离开喷嘴的流体缓冲。

    • The invention concerns an impacting device capable of being advantageously used in an impact hammer and/or a drill for releasing by impact tools blocked in rocks. For this purpose, an impact impetus supplied by an impact piston (1) is modified by means of a impact-deflecting device comprising a sliding lever (8) and a deflecting lever (12), such that said impact is carried out in a releasing impact direction (F) opposite the normal impact direction (B) and is transmitted to a tool (4) via a slide (15) and a locking lever (6). The tool (4) is already released after a few strokes produced by the impact piston (1). Said impact device is suitable for both unilateral air springs and double air springs.
