The invention discloses a traction rope electric hoist without rope length limitation, belongs to the field of electric hoists, solves the problem of potential safety hazards of the electric hoist caused by the possibility of slipping of a traction rope, and adopts the technical scheme that the traction rope electric hoist mainly comprises a machine shell, a pressing wheel assembly, two rollers mounted on the machine shell and a driving mechanism for driving the two rollers, the two rollers are in transmission connection to achieve synchronous rotation, a plurality of circles of rope grooves for winding a traction rope are formed in the rollers, the pressing wheel assembly acts on the traction rope to enable the traction rope to be kept tensioned, one end of the traction rope is a traction end for hanging a heavy object, the other end of the traction rope is a free end, the pressing wheel assembly comprises a plurality of rotatable pressing wheels, and the pressing wheels enter the rope grooves and press the traction rope. Therefore, static friction is formed between the traction rope and the roller. The invention is mainly used for reducing the possibility of slipping of the traction rope.

    本发明公开一种不限绳长的牵引绳电动葫芦,属于电动葫芦领域,解决了牵引绳存在打滑的可能性,导致电动葫芦存在安全隐患的问题,解决该问题的技术方案主要是包括机壳、压轮组件、安装于机壳的两个滚筒和驱动两个滚筒的驱动机构,两个滚筒传动连接实现同步转动,滚筒上设有绕装牵引绳的多圈绳槽,压轮组件作用于牵引绳以使牵引绳保持张紧,牵引绳一端为挂接重物的牵引端,另一端为自由端,所述压轮组件包括多个可转动的压轮,压轮进入到绳槽内并压紧牵引绳,以使牵引绳与滚筒形成静摩擦。本发明主要用于降低牵引绳发生打滑的可能性。
