Therefore, when the cable body 102 stops synchronous action with the lifting equipment due to scratching, the safety pin 104 can be driven to be switched from the connection state to the disconnection state, the connecting component is driven to act to trigger the switch component 100 and control the lifting equipment to stop, the cable body 102 is prevented from being broken, and personal safety of workers is guaranteed.
Specifically, please refer to fig. 1 to 5, the switch assembly 100 is mounted on the lifting device and electrically connected to the cable body 102, wherein the switch assembly 100 may use a micro switch, and since the cable breakage preventing apparatus for the lifting device is mainly applied to the lifting device, the micro switch is adopted to ensure that the contacts can be switched at the same position even if the micro switch is repeatedly turned on or off, so that the position detection error is small; and the arc duration is short, so the damage to the contact is less, and the durability is improved, thereby the action sensitivity and the use durability of the cable breaking-proof device for the lifting equipment can be ensured.
Through being connected switch assembly 100 and cable body 102 electricity, when having guaranteed the micro-gap switch action, can respond rapidly and control the jacking equipment through the power failure of cable body 102 and shut down, for example in the in-process that the jacking equipment rose or descends, when the micro-gap switch action, can control the jacking equipment through cable body 102 rapidly and stop, and then can guarantee the timely stopping of jacking equipment effectively, guaranteed passenger's security in the jacking equipment.
The connecting component mainly plays a role in hanging the cable body 102 so as to enable the cable body 102 to be linked with the switch component 100, in other words, the cable body 102 is hung on the lifting equipment through the connecting component and is linked with the switch component 100 through the connecting component. That is, when the cable body 102 connected to the connecting assembly stops synchronous action with the lifting device due to scratching, the micro switch can be triggered synchronously to control the lifting device through pulling the connecting assembly.
The safety pin 104 is disposed on the connecting component, that is, the safety pin 104 and the connecting component can move synchronously. And also. The safety pin 104 can be switched from the connection state to the disconnection state, that is, the safety pin 104 has two different states, namely, the connection state and the disconnection state, and the connection state can only be switched to the disconnection state between the two states, and the disconnection state cannot be switched back to the connection state.
When the safety pin 104 is in the connection state, the lifting device can drive the cable body 102 to lift; when the safety pin 104 is in the disconnected state, the cable body 102 can pull the connecting assembly to act so as to trigger the switch assembly 100, and the switch assembly 100 controls the lifting device to stop.
