The invention relates to the technical field of escalators, and discloses an escalator chain tensioning device, which comprises a driving wheel, a driving gear, a chain, an escalator shell and a current transformer; the driving wheel and the driving gear are in transmission connection through the chain; a parallel support is fixedly installed on the escalator shell and located between the drivingwheel and the chain; a driven wheel gear is movably installed at the bottom of the parallel support and engaged with the right side of the chain; and a square sleeve is fixedly installed at the top ofthe parallel support, and a steel block is movably connected into the square sleeve in a sleeved mode. Through the arrangement of a steel block and a pressing wheel, downward pressure is applied to the pressing wheel by utilizing the gravity of the steel block, and then downward pressure is applied to the chain between the driving wheel and the driving gear, so that the chain is pressed and tensioned, the phenomena of tooth disengaging and tooth skipping caused by shaking and excessive extension in the transmission process are effectively prevented, and the transmission safety is effectivelyincreased.
本发明涉及自动扶梯技术领域,且公开了一种自动扶梯链条张紧装置,包括主动轮、驱动齿轮、链条、扶梯外壳和电流互感器,所述主动轮和驱动齿轮通过链条传动连接,所述扶梯外壳上且位于主动轮和链条的之间固定安装有平行支架,所述平行支架的底部活动安装有从轮齿轮,所述从轮齿轮与链条的右侧啮合,所述平行支架的顶部固定安装有方形套,所述方形套的内部活动套接有钢制块。通过钢制块和压紧轮的设置,利用钢制块的重力,对压紧轮施加向下的压力,进而对主动轮和驱动齿轮之间的链条施加向下的压力,使得链条进行受压张紧,有效防止其在传动过程中抖动,和伸长太多造成的脱齿和跳齿现象,有效增加传动的安全性。
