The invention relates to a straight barrel crane. The straight barrel crane comprises a rack, a first main shaft, a winding barrel, a protective sleeve and a wire pressing wheel, wherein the first main shaft is rotatably mounted on the rack and is in driving connection with a motor; the winding barrel is mounted on the first main shaft and can move along the axial direction of the first main shaft while rotating along with the first main shaft, so that the winding and unwinding position of a steel wire rope wound on the winding barrel keeps unchanged; the protective sleeve is mounted on the rack and sleeves the winding barrel, can move along the axial direction of the first main shaft along with the winding barrel and is provided with an axial opening for winding and unwinding the steel wire rope; the wire pressing wheel is mounted on the rack and is in driving connection with the motor; and the wire pressing wheel is located at the winding and unwinding position and presses against the steel wire rope. According to the straight barrel crane, the protective sleeve is arranged outside the winding barrel so that the steel wire rope does not have a loosening or jumping phenomenon under any condition and the service life of the crane is greatly prolonged; and meanwhile, the wire pressing wheel is driven by the motor so that a very good pressing force can be provided and the steel wire rope does not jump.

    本发明涉及一种直筒吊机,其可包括:机架;第一主轴,可转动地安装在机架上并与电机驱动连接;绕线筒,安装在第一主轴上并能在随着第一主轴转动的同时沿第一主轴的轴向方向运动,使得绕在绕线筒上的钢丝绳的收放位置保持不变;护套,安装在机架上并套在绕线筒的外面,能随着绕线筒沿第一主轴的轴向方向运动,护套具有让位于钢丝绳收放的轴向开口;以及压线轮,安装在机架上并与电机驱动连接,压线轮位于收放位置并压靠在钢丝绳上。本发明通过在绕线筒外面的护套,可以确保钢丝绳在任何情况下都不会出现松脱或跳圈现象,大大提高吊机的使用寿命,同时由于压线轮是由电机带动的,可以提供很好的压紧力,确保钢丝绳不会跳动。
