Specific embodiment
The present invention will be further described by 1-2 with reference to the accompanying drawing.
As shown in Figure 1, the present apparatus mainly by: for detecting steel wire 3, the acoustic-optic alarm, delay of haulage cable Relay, composition.The steel wire 3 of strip is located at immediately below haulage cable 2, is mounted on derrick by the insulator 4 at both ends 6, between winding houses 1.The steel wire is the rectangular metal net that length is much larger than width, the insulation that each vertex passes through installation Son is fixed.The signal wire 9 that steel wire 3 connects is concatenated with acoustic-optic alarm, then accesses one end of power supply, the other end of power supply It is connect with elevator drum 5;Time-delay relay is in parallel with acoustic-optic alarm, and time-delay relay normally-closed contact accesses elevator letter Number locked loop.
Preferably, the steel wire 3 is parallel with haulage cable.3 both ends of steel wire are separately fixed at by insulator On winding houses and derrick, it is arranged in parallel with the haulage cable 2 of tensioning state, and keep a fixed spacing.The sound-light alarm Device is concatenated by warning lamp 10 and alarm bell 11.Warning lamp and alarm bell can use the combined aural and visual alarm of operating voltage 24V.
By directly leading out 24V DC power supply on winding houses control panel or by AC/DC power module, cathode, which is connected to, to be mentioned It rises on machine cylinder side wall (i.e. elevator with connecing DC power supply), anode is connected on steel wire.On electrode line road, steel wire 3 connects The signal wire connect is connected in series with warning lamp, alarm bell, then accesses positive terminal.Time-delay relay coil one end and signal wire connect It connects, the other end is connect with positive terminal, i.e., in parallel with acoustic-optic alarm.The time-delay relay is energization delay relay, is prolonged When relay it is in parallel with acoustic-optic alarm, time-delay relay normally-closed contact access elevator signal block circuit.Be delayed relay Device obtain it is electric reach setting time, normally-closed contact just will disconnect, so disconnect elevator signal block circuit, elevator contactor Control loop power loss, elevator are shut down.
In the process of running, haulage cable is typically in tension, at regular intervals with steel wire, 24V AC line Road is in an off state, and warning lamp, alarm bell are failure to actuate, time-delay relay normally-closed contact, that is, output end, is in normally off, is promoted The conducting of owner's power supply, elevator are in operating status.As shown in phantom in Figure 2, when there is situations such as card tank, haulage cable 2 It relaxes, since wirerope self weight generation is sagging, haulage cable will be contacted with steel wire, and 24V DC power supply is connected, this When warning lamp and alarm bell movement, prompt operation driver's haulage cable occur slack rope, time-delay relay simultaneously it is electric, be delayed one section Time is more than setting value, will be acted, and output end normally-closed contact disconnects, and the main power source locked loop of elevator is disconnected, and is promoted Machine stops working.
