Structure.When being arranged to multilayered structure, in the settable same latch assembly of every layer of structure, to greatly improve hydraulic liter
The stability and safety of vehicle drop.
The implementation principle of the present embodiment are as follows: when using the lift truck, adjust good position first, then step on brake(-holder) block
141, hydraulic stem pushes first connecting rod 321 and second connecting rod 421, and first connecting rod 321 pushes the expansion of first support arm 3, second to connect
Bar 421 push second support arm 4 be unfolded, thus drive carrying platform 2 rise, carrying platform 2 during rising, rack gear 51 with
Rise together, rack gear 51 drives the gear 52 that is meshed to rotate, and rotates together with gear 52 with dog end 53, ratchet 53 exists
Can constantly stir pawl 54 when rotation but will not be by 54 stop of pawl, and when hydraulic cylinder 6 breaks down, hydraulic cylinder 6 is logical
The jack-up power failure of hydraulic stem application is crossed, therefore carrying platform 2 has downward trend, pawl 54 is against on ratchet 53 at this time,
Prevent ratchet 53 from inverting, so that engaged transmission will not occur at 52 rack gear 51 of gear, therefore the carrying affixed with rack gear 51
Platform 2 will not decline, and improve security performance.And when needing to decline carrying platform 2, using cylinder 12 with 11 edge of movable slider
Sliding slot 111 slide so that pawl 54 is detached from ratchet 53, therefore smoothly carrying platform 2 can be lowered.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
