The invention relates to the technical field of escalators, and discloses a commercial escalator capable of achieving self-triggering deceleration and preventing an escalator from backing. The commercial escalator comprises a frame body, a first sliding groove is formed in the bottom of the frame body, a first sliding block is connected to the interior of the first sliding groove in a sliding manner, first springs are elastically connected to the bottom end of the first sliding block, a first magnetic block is fixedly connected to the middle of the first sliding block, and first rotating rods are hinged to the top end of the first sliding block. According to the commercial escalator capable of achieving self-triggering deceleration and preventing the escalator from backing, a ratchet wheel rotates to drive a pawl clamped to the upper side of the ratchet wheel to be synchronously ejected upwards, the rotating direction of the ratchet wheel is locked, the effect of preventing the chain wheel from reversing when a chain is broken is achieved, when the rotating speed of a driving disc is too high, a centrifugal block moves under the centrifugal force effect so that communication contacts can communicate, an electromagnet is electrified to attrack the first magnetic block, the first sliding block is ejected upwards to open abutting rods to drive first rolling wheels to be tightly attached to the surface of the driving disc, the rotating speed of the driving disc is reduced, and the safety of the equipment is improved.

    本发明涉及自动扶梯技术领域,且公开了一种自触发减速和防止扶梯倒退的商用扶梯,包括架体,所述架体的底部开设有滑槽一,所述滑槽一的内部滑动连接有滑块一,所述滑块一的底端弹性连接有弹簧一,所述滑块一,所述滑块一的中部固定连接有磁块一,所述滑块一的顶端铰接有转杆一。该自触发减速和防止扶梯倒退的商用扶梯,通过棘轮转动带动卡接在棘轮上侧的棘爪同步上顶,锁定棘轮转动方向,达到链条断裂时防止链轮反转的效果,在主动盘转速过快时,离心块受到离心力作用移动使连通触点连通,电磁铁通电吸引磁块一,滑块一上顶使抵杆张开带动滚轮一贴紧主动盘表面,降低主动盘的转速,提高设备的安全性。
