353, the lockhole 342 for locking the activity securing rod 353 is provided with the sliding groove structure 341 of the movable hook 34.
Working process and principle of the invention are：
When needing to carry out ladder-type sleepers lifting transhipment, fork truck is operated first by the carrier of pallet fork insertion ladder-type sleepers suspender
The fork pockets 13 of the lower section of body 11, then opens the positioning pin 141 of positioner 14 and the movable securing rod of suspension hook locking device 35
353, and movable hook 34 is slided at the two short side stent both ends locking pin 38 of left and right of power transmission frame body 31, then handling this suspender
Precalculated position above to ladder-type sleepers, then bottom surface that suspender is slowly dropped to locating piece 33 touches the upper table of ladder-type sleepers
Face, then movable securing rod 353 is pulled, 34 slid inward of movable hook at both ends, lockhole is inserted into by the hook of movable securing rod 353
342 locking ladder-type sleepers, then put down the positioning pin 141 of positioner 14, prevent movable hanging apparatus 3 in the process of running with
Meaning rotary oscillation；Then operation fork truck slowly lifts by crane, and first passes through the suspension hook that stress is transmitted to suspension arrangement 2 by carrying frame body 11
21, then 21 stress of suspension hook is transmitted to by movable hook 34 by power transmission frame body 31 and slings ladder-type sleepers, then fork truck is operated by ladder
The handling of shape sleeper is to designated position, in the process, 2 complex equilibrium support device 12 of suspension arrangement, angle adjustment track 32 with
And positioning pin 141, it is ensured that movable hanging apparatus 3 and ladder-type sleepers keep same level with ground all the time, avoid ladder-type sleepers from existing
It is impaired because rocking in transportational process, and the horizontal direction rotation of 3 certain angle of control activity hanging apparatus, carried with reference to fork truck traveling
The movement of confession, realizes and is deposited into target location by ladder-type sleepers are quick, accurate, intact；Finally open the positioning of positioner 14
The movable securing rod 353 of pin 141 and suspension hook locking device 35, slides movable hook 34 to both ends and discharges ladder-type sleepers, striker fork
Car slowly slings empty suspender, completes this handling process.
The present invention and embodiments thereof are described above in conjunction with attached drawing, this describes no restricted, institute in attached drawing
What is shown is also one of embodiments of the present invention, and actual structure is not limited thereto.So if common skill of this area
Art personnel are enlightened by it, without departing from the spirit of the invention, without creatively designing and the technical solution
Similar frame mode and embodiment, are within the scope of protection of the invention.
