Clamp device connection, in order to drive safety tongs device to operate.
10, when magnetic conductive device and magnet are fixed, and coil device slides, which drives connecting rod, and makes to connect
Bar pulls the safety tongs device of lower section.
11, the magnetizing direction of the magnet is magnet along the connection direction of first end to second end, and magnetic cavity is needed to generate and be hung down
Directly in the maximum magnetic line of force of the first end of magnet, and make magnetic cavity that there is enough covering spaces, in order to which winding coil is logical
There is in magnetic cavity enough spaces when electric.
It 12, is that the linear drive apparatus motoring torque is made linearly to possess stronger handling, therefore the magnetic line of force in magnetic cavity
Intensity should be linear homogeneous, and the thickness of magnetic conductive device and the thickness of magnet body will affect its magnetic to a certain extent
The density of line of force distribution, therefore it is required that magnetic conductive device and magnet material consistency of thickness, the first end of magnet and magnetizing for second end
Intensity is consistent, further increases the stability of torque in linear drive apparatus.
13, in the state of safety tongs device non-trigger protection, spring arrangement is constantly in accumulation of energy state to be triggered, when
When carriage rapid decrease occurs because of failure, control system stops powering to coil device, and peace is triggered under the action of spring arrangement
The protection mechanism of full clamp device, spring arrangement discharge mechanical energy drive link, the company by overhead gage, lower baffle plate and spring mechanism
For bar by pulling fixed mechanism, which jacks up safety tongs wedge, which matches with the sliding of the second inclined side
It closes, clamps safety tongs wedge, and then carry out braking protection to the rapid decrease of carriage.
