Afterwards the rear side surface of the end nut 4632 after tightening position and described first of end nut 4633 against.So that threaded rod 461
It is more firm to lock.
If it was found that 3 height of pallet fork is higher than designated value locking nut group can be unscrewed to increase the effective length of connecting rod 43, from
And support wheel arm 44 is driven to reduce the prong of pallet fork 3 around the 4th rotation counterclockwise of axis 32.Similarly, if 3 height of discovery pallet fork is low
In designated value, locking nut group can be unscrewed to shorten the effective length of connecting rod 43, to drive support wheel arm 44 around the 4th axis
32 rotate clockwise, and increase the prong of pallet fork 3.
Certainly, when discovery left and right two pallet forks, 3 height are inconsistent (left and right two pallet fork 3 one is mainly reflected in land,
One does not land), also adjustable locking nut group 463 changes the effective length of connecting rod 43, to adjust the height of pallet fork 3.
Above-mentioned length of connecting rod regulating mechanism 46 can efficiently solve the deformation of rear 2 and pallet fork 3 in welding with
And the accumulated error of work pieces process, it is also avoided that when 3 excessive height of pallet fork occur, too low, pallet fork is uneven and dismantles raising
Mechanism can greatly save the time, improve efficiency.
In the above-described embodiments, pallet fork 3 and link mechanism 4 only illustrate by taking the structure of side as an example, the structure pair of the other side
Claim setting.
The tray carriage lifting mechanism of the embodiment of the present invention, driving device can drive rear and pallet fork with respect to front truck when working
Body upward sliding (raising) along the vertical direction, since the limited block being fixedly installed on front of the car is supported in the top of idler wheel, idler wheel
Raising movement limited so that rocker arm with respect to pallet fork front end rotate, be pulled along connecting rod, meanwhile, support wheel arm with respect to goods
The rear end of fork rotates, so that support wheel arm is played a supporting role.Compared with prior art, stress when connecting rod works is by by buckling
For tension, the stress condition of connecting rod is substantially improved, reduces the bending deformation risk of connecting rod.In addition, rear is with respect to front truck
