技术领域 Technical field
本发明涉及起重机机械技术领域， 尤其涉及一种多层缠绕绳槽卷筒及 其加工方法及包括该卷筒的起重机。 The present invention relates to the field of crane machinery technology, and more particularly to a multi-layer winding rope drum and a processing method thereof and a crane including the same.
背景技术 Background technique
目前， 在工程机械领域， 通常采用起重设备的起升完成重物的起吊， 具体来说就是通过钢丝绳在卷筒上的卷入和放出实现重物的升降。 随着起 重机的大型化， 大型卷筒的应用越来越多， 一般来说， 起重机的起升高度 越高， 钢丝绳在卷筒上卷绕的圏数就越多； 起重的重量越大， 所需的钢丝 绳的直径和钢丝绳的倍率就越大， 卷绕在卷筒上的钢丝绳量就越大， 卷筒 承受的载荷也越大。 同时， 随着卷筒上卷绕的钢丝绳的层数、 圏数增多， 就越容易出现跳绳、 叠绳等乱绳现象， 轻则影响到钢丝绳的使用寿命， 重 则发生安全事故。 At present, in the field of construction machinery, lifting of lifting equipment is usually carried out to complete the lifting of heavy objects, specifically, the lifting and lowering of the weight by the winding and discharging of the wire rope on the reel. With the increase of the size of the crane, the application of large rolls is increasing. Generally speaking, the higher the lifting height of the crane, the more the number of turns of the wire rope on the reel; the greater the weight of the lifting, The larger the diameter of the required wire rope and the magnification of the wire rope, the greater the amount of wire rope wound on the drum and the greater the load on the drum. At the same time, as the number of layers and the number of turns of the wire rope wound on the reel increase, the more likely the ropes are skipped, the ropes are piled up, etc., and the service life of the wire rope is affected, and safety accidents occur.
现阶段国内外使用的专门用于多层缠绕的卷筒， 通常有两种结构： 一 种多层缠绕卷筒的卷筒整体铸造而成， 结构形式较筒单， 但由于铸造绳槽 精度低， 与钢丝绳配合时易发生陷绳、 乱绳， 从而影响钢丝绳的使用寿命， 且中间筒体与法兰盘连接处易出现沙眼、 气孔等缺陷， 又会影响卷筒的强 度， 这就增加了起重机的操作成本， 降低了安全性； 另一种多层缠绕卷筒 的绳槽分割为三部分进行机加工， 其中， 两侧壁法兰盘上各分割 1.5个绳 槽， 中间卷筒上为剩余绳槽， 法兰盘和中间卷筒通过螺栓联接， 然而， 这 种分割结构不利于绳槽对接装配， 且整体结构形式较为复杂。 At present, the reel used exclusively for multi-layer winding at home and abroad usually has two structures: a multi-layer winding reel is integrally cast, and the structure is simpler, but the casting rope groove has low precision. When it is matched with the wire rope, the rope rope and the rope are prone to occur, thereby affecting the service life of the wire rope, and the joint between the middle cylinder and the flange is prone to defects such as trachoma and air holes, which affects the strength of the reel, which increases the The operating cost of the crane reduces safety; the rope groove of another multi-layer winding reel is divided into three parts for machining, wherein the two side wall flanges are divided into 1.5 rope grooves, and the middle reel is The remaining rope grooves, flanges and intermediate rolls are connected by bolts. However, this split structure is not conducive to the docking assembly of the rope grooves, and the overall structure is complicated.
