Problems solved by technology

The cause of this accident is that the fingers of the child were brought into the junction of the handrail and the steps by the handrail during play, causing the steps to cut their fingers, and the most fundamental reason was that foreign objects were stuck into the handrail and the steps. In between, the escalator protection switch does not act or does not act in time, causing the escalator to keep running for a certain distance, causing multiple injuries to the body

Abstract

The invention discloses a protection device for an entrance-exit of an escalator. The protection device comprises a rubber sleeve, conductive elastic sheets and a safety circuit, wherein one end of the rubber sleeve is fixedly arranged on an entrance-exit panel of the escalator, a first opening is formed in the upper part of the rubber sleeve along a length direction, a second opening is formed in the bottom of the rubber sleeve along the length direction, and the two sides of the second opening are mutually bonded; each of the conductive elastic sheets is composed of two spring sheets in elastic contact, the plurality of conductive elastic sheets are arranged on the second opening at intervals, and every two paired spring sheets are separately arranged on one side of the second opening; the safety circuit is connected with a power supply of a drive mechanism for the escalator, and each of the conductive elastic sheets is serially arranged in the safety circuit; and each pair of the spring sheets is in normally-closed contact, any one pair of the spring sheets is disconnected, and the power supply is switched off and a brake device for the escalator is started. The protection device disclosed by the invention effectively avoids the accidents of personal injuries and escalator step damages.

Description

technical field [0001] The invention relates to a safety protection device for an escalator, more specifically, the invention relates to a protection device for an entrance and exit of an escalator. Background technique [0002] In addition to the great convenience brought by the escalator (moving sidewalk), accidents often occur. In the case of personal injury during the operation of the escalator, the number of injuries caused by fingers stuck between the handrail and the steps in operation far exceeds that of the escalator. Personal injury accidents caused by failure of other parts. The cause of this accident is that the fingers of the child were brought into the junction of the handrail and the steps by the handrail during play, causing the steps to cut their fingers, and the most fundamental reason was that foreign objects were stuck into the handrail and the steps. During the interval, the escalator protection switch did not act or did not act in time, causing the esc...
