The invention relates to the field of wind power generation, in particular to a tower lifter, a tower and a wind power generation set. The tower lifter comprises a lifter body, a driving device, a limiting device and an overload protection device. A cat ladder is arranged in the height direction of the tower, and a rack is arranged in the length direction of the cat ladder; the driving device is arranged on the lifter body and is engaged to the rack to drive the lifter body to lift along the cat ladder; the limiting device is arranged on the top and/or on the bottom of the lifter body; the overload protection device is arranged on the lifter body to detect a load in the lifter body; and the limiting device, the overload protection device and the driving device are in communication connection to a control device. According to the tower lifter, the stability of the tower lifter in the lifting process can be guaranteed, the structure of the tower lifter is enlarged, and the tower lifter can bear a larger load. Meanwhile, the tower lifter further can play roles of pre-warning, limiting and detecting the load change in the tower lifter in real time, so that the safety performance of thetower lifter is improved.

    本发明涉及风力发电领域,涉及一种塔筒升降机、塔筒及风力发电机组。塔筒升降机包括升降机本体、驱动装置、限位装置以及过载保护装置;沿塔筒的高度方向设置有爬梯,沿爬梯的长度方向设置有齿条;驱动装置设置在升降机本体上并与齿条啮合,以带动升降机本体沿着爬梯升降;限位装置设置在升降机本体的顶部和/或底部;过载保护装置设置在升降机本体上以检测升降机本体内部的载荷;限位装置、过载保护装置以及驱动装置与控制装置通信连接。该塔筒升降机能够保证塔筒升降机升降过程中的稳定性、实现塔筒升降机的结构大型化、可以承载更大的载荷。同时还能够起到预警、限位、实时检测塔筒升降机内的载荷变化的作用,提升了该塔筒升降机的安全性能。
