Handrail safety control device, conveying system and handrail safety control method

Abstract

The invention relates to a handrail safety control device, a conveying system and a handrail safety control method. The handrail safety control device is used for the conveying system with a handrail; the handrail comprises a body and a handrail belt; the handrail belt is driven by power to move relative to the body; the handrail belt and the body are in a joint state or a disengagement state; the handrail safety control device comprises a contact part and a signal generating part; the contact part is arranged in a preset section of the handrail and is respectively in a first state or a second state when the handrail belt in the preset section is in the joint state or the disengagement state; the contact part is in contact with the handrail belt in the first state, and is at least partially disengaged from the handrail belt in the second state; and the signal generating part is configured to generate a response signal in response to switching of the contact part between the first state and the second state. Through adoption of the handrail safety control device, the conveying system and the handrail safety control method, the safety performance of conveying systems such as an escalator can be effectively improved, and the safety of passengers and equipment is guaranteed.

Description

Technical field [0001] The present invention relates to the field of electromechanical technologies, in particular to handrail safety control devices, delivery systems, and handrail safety control methods. Background technique [0002] Transport systems such as escalators, automatic sidewalks have been widely used, which can have great convenience to people's work, travel, etc. Although prior art has provided many types of delivery systems to meet a variety of different needs, they still have some shortcomings in terms of structural construction, safety reliability, manufacturing and maintenance cost, operating performance, etc. [0003] For example, for example figure 1 As shown in these existing delivery systems, an armrest is typically provided, and the armrest generally includes two parts, i.e., a fixed mounted body 22 and an arm strap 21 that is detachable to the body 22, and then passed For example, a power device such as an electric motor drives the armrest strip 21 to mov...

AI Technical Summary

Problems solved by technology

However, in some undesired cases, such as figure 2 (a) and figure 2 As shown in (b), the handrail 21 in some areas may be detached from the main body 22 on one side or even both sides. This detached state will bring safety risks to the equipment operation and passengers of the conveying system, and may even cause serious damage. damage

Although many devices are known for test protection, anti-breakage protection, etc. for handrails, they cannot fully meet the safety protection requirements for handrails in conveying systems.
