Height when entering plant area can be limited, in practical work process, device height often changes, for example crane exists
It is huge with height difference during lifting operation when driving, therefore the device can not protect the safety of running equipment.
Chinese patent notification number CN202415005U discloses a kind of substation crane sling height attention device, conducive to limit
Height rope one end is arranged on crane, and with alarm triggering device on the ground is set to connect, alarm triggering device includes the other end
The free chamber of traverse and the electrode cavity stood up, free chamber are connected with electrode cavity by interface, setting steel ball, electrode in free chamber
Intracavitary sets electrode, and electrode forms supervisor's attention device alarm electricity with power supply, warning device, alarm lamp and wireless signal transmitter
Road, crane operation person's attention device are made of wireless signal receiver, alarming horn and supply unit.During more than limit for height, limit for height rope
Alarm triggering device is turned in drawing, and steel ball is dropped into electrode cavity, and supervisor's attention device warning circuit is connected, and warning device sends out police
Report, alarm lamp flicker, while the signal of wireless signal transmitter transmitting is received by wireless signal receiver, alarming horn sends out police
Report, so as to and alarm, be automatically reminded to, prevent crane superelevation, avoid accident.The device at runtime, due to crane
Peak is often positioned in the surface of lifting object, and arm of crane needs not stop to move, thus limit for height rope can not ensure on ground
Alarm triggering device connection, therefore be unsuitable for onsite application.
