In above-mentioned printed matter transport lowering or hoisting gear, the end of described rack provided with rotating breast board, rack it is interior
Portion is equipped with pull rope, and one end of pull rope is connected with rotating the turning end of breast board, and the other end of pull rope is connected with mounting bracket.
In foregoing printed matter transport lowering or hoisting gear, the rear end of described hydraulic cylinder is connected with first throttle valve through oil circuit
With the first check valve, first throttle valve and the first check valve are connected with three-position four-way electromagnetic directional valve, and first throttle valve and
One check valve is connected for P mouthfuls with three-position four-way electromagnetic directional valve;The T mouths of three-position four-way electromagnetic directional valve be connected with second throttle and
Second check valve, second throttle and the second check valve are connected with the rod end of hydraulic cylinder;Described 3-position 4-way electromagnetic switch
The A mouths of valve are connected with constant displacement pump, and constant displacement pump is connected with fuel tank, and the A mouths of described three-position four-way electromagnetic directional valve are also through overflow valve
It is connected with fuel tank;The B mouths of described three-position four-way electromagnetic directional valve are connected with fuel tank.
Compared with prior art, the present invention includes rack and mounting bracket, and rack is used to load printed matter, and mounting bracket is used
In on the haulage vehicles such as automobile;Principal arm, first connecting rod and second connecting rod, mounting bracket are provided between rack and mounting bracket
On be additionally provided with hydraulic cylinder, by the flexible rotation second connecting rod of hydraulic cylinder so that first connecting rod and second connecting rod are shunk,
Drive rack up mutually neat with vehicle car platform, so as to facilitate the carrying of printed matter.And rack includes side plate and movement
Plate, is provided with threaded rod between side plate and movable plate, by rotating the distance of binding nut, regulation side plate and movable plate, so that real
The fixation of existing printed matter, prevents printed matter from being dropped from rack.Further, in the end of rack provided with rotation breast board,
Pull rope is provided with rack, one end and the mounting bracket of pull rope are fixed, when carrying rotation when loaded, pull rope is exceptionally straight, this
When rotate breast board extend, prevent the printed matter on rack from dropping;Completed when loading, pull rope fluffs, rotate breast board and fall, this
When printed matter can be removed with plane, it is very convenient.
