1. A safety comb plate 100 of an escalator 1 including a plate body 110 fixed to the front of a landing plate 10 and a comb portion 120 provided at the front end of the plate body 110 and in which a plurality of teeth protruded to the front towards a foothold 20 maintain a constant gap, wherein at teeth 122, a detection line 130 that blocks transmission of a detection signal with a control means 40 that controls driving of the escalator by disconnecting is provided, when the teeth 122 are damaged,
the control means 40 determines that the teeth 122 are damaged, when a detection signal is not input from the detection line 130 to stop a driving motor 30 that drives the foothold 20 of the escalator 1 and to output with sound a failure message of the escalator through a speaker 60, when it is determined that the teeth 122 are damaged, the control means 40 transmits comb plate repair request information notifying that the teeth 122 of the comb plate 100 are damaged to a smart phone, which is a mobile terminal 200 of a manager through a remote communication module 70, the plate body 110 and the comb portion 120 of the comb plate 100 are dividedly produced, and at the front end of the plate body 110, insertion grooves 116 are formed in a right and left side direction, and at the rear end of the comb portion 120, insertion protrusions 126 inserted into the insertion groove 116 are formed in a right and left side direction, and by inserting the insertion protrusion 126 of the comb portion 120 at one side surface along the insertion groove 116 formed at the front end of the plate body 110, the plate body 110 and the comb portion 120 are integrally coupled, and at a side surface of the teeth 122 protruded to the front of the comb portion 120, a Printed Circuit Board (PCB) insertion groove 122b is formed, and at the PCB insertion groove 122b, a PCB 131 having a pattern 131a in which a detection signal of the detection line 130 flows is fixed. |
