Bent guide rail safety device and system

Abstract

The invention discloses a bent guide rail safety device. The device comprises first guide rails, second guide rails and pressing rails. The upper end of a first swing arm is rotatably connected with the front side of one pressing rail, and the lower end of the first swing arm is rotatably connected with a truss. A first torsion bar spring comprises a first hook section hung on the first swing arm and a first torsion bar section connected with the first hook section. The upper end of a second swing arm is rotatably connected with the rear side of one pressing rail, and the lower end of the second swing arm is rotatably connected with the truss. A second torsion bar spring comprises a second hook section hung on the second swing arm and a second torsion bar section connected with the second hook section. A near-end limiting block is arranged below one pressing rail. The device has a bent section step safety monitoring function, when auxiliary wheels of the step are abnormally lifted at the bent section and exceed a threshold value, a monitor is triggered, a signal is sent to a control system, an escalator is stopped, and safety is ensured.

Description

technical field [0001] The invention relates to the technical field of elevator equipment, in particular to a curved guide rail safety device. Background technique [0002] The passenger section of the escalator can usually be divided into upper horizontal section, upper curved section, inclined section, lower curved section and lower horizontal section; the upper curved section is the transition section between the upper horizontal section and the inclined section, and the lower curved section is the lower horizontal section. The transition zone between the slope section and the inclined section; when the continuously running steps are in the upper curved section and the lower curved section, due to the relative displacement in the height direction between adjacent steps, when the step kick plate is squeezed by shoes and other objects to produce an upward movement The friction force makes the rear end of the step (the position of the step auxiliary wheel) lift upwards, ther...

Problems solved by technology

[0003] Patent CN202010153382.7 A cascade anti-lift braking device and escalator equipment, which can not only prevent the abnormal lifting of the cascade body when the escalator equipment is in normal operation, but also distribute it when there is an emergency braking demand. The device for braking each step can effectively solve the above problems; but usually, the escalator already includes the main brake, and if there is no need for additional brakes, or if additional brakes are configured to meet customer needs, distribution The function of the brake step undoubtedly increases the cost
