Oil cylinder, breaking hammer and pile hammer
The invention provides an oil cylinder, a breaking hammer and a pile hammer. The oil cylinder is used for a breaking hammer or a pile hammer and comprises an inner cylinder barrel; the piston assembly comprises a piston rod and a piston connected to the piston rod, the piston is in sliding fit with the inner cylinder barrel, and the piston and the inner cylinder barrel form a first working cavity and a second working cavity which are located at the two ends of the piston; the gas container is used for containing gas and is connected with the first working cavity, so that the gas serves as a working medium of the first working cavity; the outer cylinder barrel is arranged on the outer side of the inner cylinder barrel in a sleeving mode, a fluid channel used for containing hydraulic oil is formed between the outer cylinder barrel and the inner cylinder barrel, the fluid channel is communicated with the second working cavity so that the hydraulic oil can serve as a working medium of the second working cavity, and a working port is formed in the outer cylinder barrel and connected with the fluid channel; the hydraulic oil flows into or out of the second working cavity through the fluid channel. The breaking hammer comprises the oil cylinder. The pile hammer comprises the oil cylinder. The striking energy and the working efficiency of the breaking hammer or the pile hammer can be improved.
本公开提供了一种油缸、破碎锤和打桩锤。油缸用于破碎锤或打桩锤，包括：内缸筒；活塞组件，包括活塞杆和连接于活塞杆上的活塞，活塞与内缸筒滑动配合，且与内缸筒形成位于活塞两端的第一工作腔和第二工作腔；气体容器，用于容纳气体且与第一工作腔连接，以将气体作为第一工作腔的工作介质；和外缸筒，套设于内缸筒的外侧，外缸筒与内缸筒之间形成用于容纳液压油的流体通道，流体通道与第二工作腔连通，以将液压油作为第二工作腔的工作介质，外缸筒上设置有工作端口，工作端口与流体通道连接，以使液压油通过流体通道流入或流出第二工作腔。破碎锤包括上述油缸。打桩锤包括上述油缸。本公开可以提高破碎锤或打桩锤的打击能量和工作效率。
