The invention discloses a hand strap tensioning device. The hand strap tensioning device comprises a first tensioning device and a second tensioning device. The first tensioning device is arranged onthe first side of a friction wheel, used for driving a hand strap to move, of an escalator and comprises a first tensioning wheel set in contact with the hand strap and a first spring suitable for applying tensioning force to the first tensioning wheel set. The second tensioning device is arranged on the second side, opposite to the first side, of the friction wheel and comprises a second tensioning wheel set in contact with the hand strap and a second spring suitable for applying tensioning force to the second tensioning wheel set. In the hand strap tensioning device, due to the fact that thetwo sides of the friction wheel for driving the hand strap are each provided with one set of tensioning device, it can be guaranteed that the hand strap cannot slide when the escalator moves up and down, and the escalator is suitable for running in two directions.
本发明公开一种扶手带张紧装置,包括:第一张紧装置,设置在扶梯的用于驱动扶手带移动的摩擦轮的第一侧,包括与所述扶手带接触的第一张紧轮组和适于向所述第一张紧轮组施加张紧力的第一弹簧;和第二张紧装置,设置在所述摩擦轮的与所述第一侧相对的第二侧,包括与所述扶手带接触的第二张紧轮组和适于向所述第二张紧轮组施加张紧力的第二弹簧。在本发明中,由于在驱动扶手带的摩擦轮的两侧分别设置有一套张紧装置,因此,能够保证扶梯上行和下行时扶手带都不会打滑,使得扶梯适于双向运行。
