Hammer core buffer structure of integral hydraulic hammer
The invention discloses an integral hydraulic hammer core buffer structure which comprises a buffer top shell, a piston cylinder, a piston assembly, a guide wear-resistant mechanism and an integral hammer core, the piston cylinder is installed in a buffer air containing cavity of the buffer top shell and connected with the cavity top of the buffer air containing cavity, and a piston rod is installed in the piston cylinder through the piston assembly and connected with the guide wear-resistant mechanism. The piston containing cavity is divided into a buffer gas cap cavity and a hydraulic cap cavity, the upper end of the buffer gas cap cavity is communicated with the buffer gas containing cavity through a plurality of vent holes, and the guide wear-resisting mechanisms are arranged on the side faces of the two ends of the hammer core body. According to the buffering structure, existing elastic connection buffering is changed into non-contact airtight air compression buffering, the capability of absorbing and absorbing the rebound acting force of the hammer core body is improved, damage or failure of related parts caused by connection faults is avoided, vibration and noise generated by rebound of the hammer core body are reduced, the working efficiency and stability of the hammer core are improved, and the service life of the hammer core is prolonged. The hydraulic driving device can be applied to a large-scale and extra-heavy double-acting hydraulic pile hammer, and the service life of equipment is prolonged.
本发明公开了一种整体式液压锤锤芯缓冲结构，包括缓冲顶壳、活塞筒、活塞总成、导向耐磨机构、整体式锤芯，活塞筒安装在缓冲顶壳的缓冲气容腔内，并与缓冲气容腔的腔顶连接，活塞杆通过活塞总成安装在活塞筒内，并将活塞容腔分成缓冲气顶腔和液压顶腔，缓冲气顶腔的上端通过多个通气孔与缓冲气容腔连通，导向耐磨机构设在锤芯体的两端侧面上。该缓冲结构将现有的弹性连接缓冲改为无接触的气密性空气压缩缓冲，提高吸收和消纳锤芯体反弹作用力的能力，避免因连接故障造成的相关零部件损坏或失效，减少锤芯体反弹产生的振动及噪声，提高锤芯的工作效率和稳定性，使其能够应用于大型、超重型的双作用液压打桩锤上，延长设备使用寿命。
