Hydraulic driving device for hydraulic piling hammer
The invention relates to engineering machines, in particular to a hydraulic driving device for a hydraulic piling hammer. According to the technical scheme, the hydraulic driving device for the hydraulic piling hammer comprises a hydraulic cylinder body; the two axial ends of the hydraulic cylinder body are correspondingly provided with a cylinder cover and a valve body; the hydraulic cylinder body is internally provided with a piston and a piston rod; the hydraulic cylinder body is provided with an oil inlet; a piston cylinder is sleeved with the hydraulic cylinder body; the piston and the piston rod are located in the piston cylinder; the space between the hydraulic cylinder body and the piston cylinder is a hydraulic oil return oil space; the piston cylinder is internally provided witha lifting cavity and a driving cavity; the oil inlet is communicated with the hydraulic oil return oil space; a lifting cavity oil inlet channel is arranged at the lifting cavity; and the valve body is provided with a channel for causing the hydraulic oil return oil space to be communicated with the driving cavity and a backflow channel for causing hydraulic oil in the driving cavity to flow backinto an external oil tank. Due to the adoption of the technical scheme, the hydraulic driving device for the hydraulic piling hammer is convenient to maintain, capable of increasing the flow area of hydraulic oil, stable in sealing and capable of preventing leakage.
本发明涉及一种工程机械，特别涉及一种液压打桩锤的液压驱动装置。技术方案为：一种液压打桩锤的液压驱动装置，包括有液压缸体，液压缸体的轴向两端分别设有缸盖及阀体，液压缸体内设有活塞及活塞杆，液压缸体上开设有进油口，液压缸体内套设有活塞缸，活塞及活塞杆处于该活塞缸内，液压缸体与该活塞缸之间的空间为液压油回油空间，活塞缸内具有提升腔及驱动腔，进油口与液压油回油空间导通，提升腔处设有提升腔进油通道，阀体上设有促使液压油回油空间与驱动腔导通的通道及促使驱动腔内的液压油回流至外部油箱内的回流通道。采用上述技术方案，提供了一种便于维修、增加液压油的通留面积、密封稳定、防泄露的液压打桩锤的液压驱动装置。
