The invention relates to hand strap speed monitoring equipment and an automatic travelling device. The hand strap speed monitoring equipment comprises an installing frame, a carrying and supporting wheel, an elastic pressing assembly, a speed measuring wheel and a speed measuring sensor, wherein the carrying and supporting wheel is rotationally arranged on the installing frame, the elastic pressing assembly is arranged on the installing frame, the speed measuring wheel is rotationally arranged on the elastic pressing assembly, the speed measuring wheel and the carrying and supporting wheel areused for clamping the two opposite sides of a hand strap correspondingly, and the speed measuring sensor is arranged opposite to the speed measuring wheel; and because the carrying and supporting wheel and the speed measuring wheel correspondingly clamp and fix the upper surface and the lower surface of the hand strap, the degree of freedom of the hand strap can be well limited, the vibration ofthe hand strap caused by manufacturing and installing size errors and the like is reduced or even inhibited, and the speed measuring sensor and the speed measuring wheel are reliably ensured to keep arelatively arranged measuring pose relationship all the time, the measuring precision of the speed measuring sensor is improved, and the safety problem that a safety switch is mistakenly triggered due to large measuring errors is avoided.
本发明涉及一种扶手带速度监测设备及自动行走装置,包括:安装架;载托轮,所述载托轮转动设置于所述安装架上;弹性压紧组件,所述弹性压紧组件设置于所述安装架上;测速轮,所述测速轮转动设置于所述弹性压紧组件上,所述测速轮与所述载托轮用于分别夹持扶手带的相对两侧;及测速传感器,所述测速传感器与所述测速轮相对设置。由于载托轮和测速轮分别夹持固定扶手带的上下两面,因而能够很好的限制扶手带的自由度,减轻甚至抑制扶手带因制造、安装尺寸误差等造成的振动,确保测速传感器始终可靠与测速轮保持相对布置的测量位姿关系,提升测速传感器的测量精度,避免因测量误差大导致安全开关被误触发的安全问题发生。
