Abstract

The armrest belt break protector includes level and rack. The level set below the armrest belt is provided with rolls and switch, and is mounted on the rack and connected to the rack through a rotation shaft. The rack fixed on the guide rail bracing plate is provided with offset preventing roll. The present invention is operated on lever principle, and in case of armrest belt break, the level is turned gravitationally to trigger the switch and stop the staircase. The present invention has unique design, novel structure, easy installation and regulation and high safety and reliability, and may be used widely for escalator or moving sidewalk.

Description

technical field [0001] The invention relates to a protection device, in particular to a protection device for broken handrails of escalators or moving walks. Background technique [0002] The handrail of an escalator or moving walk is a moving part for passengers. The normal operation of the handrail provides safety for passengers, and its operating effect also directly affects the comfort of passengers. At present, most handrail breakage protection devices adopt a spring-type structure design, and the springs that are often in a compressed state are prone to failure, and are difficult to adjust, costly, and inconvenient to install and maintain. Due to the long-term use of the handrail belt and its own technical characteristics, the handrail belt breaks frequently. Therefore, it is necessary to design and develop a handrail belt broken belt protection device. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the pri...
