Reciprocating driving device, breaking hammer, pile hammer and rammer
The invention discloses a reciprocating driving device, a breaking hammer, a pile hammer and an earth rammer in the technical field of engineering machinery, and aims to solve the problems of large hydraulic oil pressure loss, small compressible ratio of a gas medium and short stroke of a piston rod of a reciprocating driving device in the prior art. Comprising an inner cylinder barrel, a piston assembly, a valve body, an outer cylinder barrel and a hammer body assembly, and the outer cylinder barrel valve body is provided with an oil inlet, an oil outlet, an oil inlet valve and an oil outlet valve; the outer cylinder barrel sleeves the outer side of the inner cylinder barrel and forms a gas medium cavity; the hammer body assembly is arranged at the tail end of the piston rod; the on-way pressure loss of hydraulic oil is low, the compressible ratio of a gas medium is high, the stroke of the piston assembly is long, integration of control components is achieved, the compactness of the overall structure of the device is improved, self-locking connection of the piston rod and the hammer body can be completed, vibration impact of the piston rod in the working process can be buffered and absorbed, and the service life of the device is prolonged. Therefore, the probability of faults such as piston rod breakage is reduced, and the service life of the device is prolonged.
本发明公开了一种工程机械技术领域的往复驱动装置、破碎锤、打桩锤及夯土机，旨在解决现有技术中的往复驱动装置存在的液压油压力损失大、气体介质的可压缩比小和活塞杆行程短的问题。包括：内缸筒、活塞组件、阀体、外缸筒和锤体总成，外缸筒阀体具有进油口、出油口、进油阀和出油阀；外缸筒套设于内缸筒的外侧并形成有气体介质腔，锤体总成设于活塞杆末端；本发明液压油的沿程压力损失低、气体介质的可压缩比高且活塞组件的行程长，实现了控制部件的集成，提高了装置整体结构的紧凑性，还可完成活塞杆与锤体的自锁连接，并可对活塞杆在工作过程中的振动冲击进行缓冲吸收，从而降低了活塞杆断裂等故障的发生概率，提高了装置的使用寿命。
