The invention discloses an automatic tensioning device and an automatic tensioning hand strap, and aims to overcome the defects that in the prior art, an escalator cannot achieve automatic tensioning, so that the maintenance frequency is high, and faults are prone to occurring. According to the technical scheme, the escalator comprises an escalator truss and a rolling wheel group arranged on the escalator truss in a sliding mode, and the rolling wheel group is matched with a handrail belt; an automatic tensioning device for pushing the roller group to slide is arranged on the escalator truss; the automatic tensioning device comprises a plunger and a tensioning spring, the head of the plunger abuts against the roller group, and the tensioning spring pushes the plunger to abut against the roller group. The plunger is continuously pushed through the tensioning spring, so that the plunger can always abut against the rolling wheel group, even if a gap exists between the rolling wheel group and the hand strap, the gap can be compensated in real time under the action of the tensioning spring, and therefore the automatic tensioning function is achieved, the maintenance frequency is reduced, and the maintenance efficiency is improved. And the escalator is effectively prevented from being stopped due to faults caused by looseness of the handrail belt.

    本发明公开了一种自动张紧装置及自动张紧扶手带,旨在解决现有技术中扶梯不能够实现自动张紧,进而使得维修频率高,且容易发生故障的不足。本发明通过以下技术方案解决上述技术问题:包括:扶梯桁架、滑动设置在扶梯桁架上的滚轮群,滚轮群与扶手带相配合;扶梯桁架上设置有用于推动滚轮群滑动的自动张紧装置;自动张紧装置包括柱塞和张紧弹簧,柱塞的头部抵接在滚轮群,张紧弹簧推动柱塞抵接在滚轮群上。本发明通过张紧弹簧持续的推动柱塞,使得柱塞能够一直保持和滚轮群的抵接,即使滚轮群和扶手带出现间隙,通过张紧弹簧的作用,能够实现即时补偿间隙,从而实现自动张紧的功能,降低了维修频率,效的防止因扶手带松弛导致故障而停梯。
