The invention relates to a hoisting chain for turnover operation of a pile feeder, which is applied to the technical field of hoisting equipment, the hoisting chain comprises a balance buffer assembly, a chain group and a connecting buckle, the chain group consists of a central chain and peripheral chains, and the peripheral chains are distributed in a circumferential array around the central chain; the center chain and the peripheral chain are connected through a guide retainer, a wear-resistant buffer sleeve is further connected outside the guide retainer, the balance buffer assembly comprises a buffer piston rod connected with the peripheral chain, the piston rod slides in the cylinder body, high-pressure chambers filled with hydraulic oil are formed in the cylinder body, and the high-pressure chambers are communicated through hydraulic communication holes and air pressure communication holes. The hoisting chain is hinged to the pile feeder and the hoisting equipment through the connecting buckles, stress of the peripheral chain is automatically balanced through the balance buffer assembly, the chains are guided and protected through the guide retainer, accurate and efficient turning over of the pile feeder is achieved, and the device has the advantages of being balanced in stress, accurate in guide, capable of achieving buffer protection, large in bearing capacity, convenient to maintain and the like.
本发明涉及应用于吊装设备技术领域的一种用于送桩器翻身作业的吊装链条,该吊装链条包括均衡缓冲组件、链条组和连接扣,链条组由中心链条和外围链条组成,外围链条围绕中心链条呈圆周阵列分布,中心链条和外围链条通过导向保持架连接,导向保持架外还连接有耐磨缓冲套,均衡缓冲组件包括与外围链条连接的缓冲活塞杆,活塞杆在缸体内滑动,缸体内形成充满液压油的高压室,高压室通过液压连通孔和气压连通孔相互连通,吊装链条通过连接扣与送桩器和吊装设备铰接,利用均衡缓冲组件自动平衡外围链条受力,利用导向保持架引导和保护链条,实现送桩器的精准高效翻身,本发明具有均衡受力、导向精准、缓冲防护、承载力大、维护方便等优点。
