In material handling field, rotary crane is wherein a kind of important handling machinery, it can complete the operations such as feeding, migration, unloading, in equipment of Vessel, rotary crane is main handling machinery, the arm of rotary crane completes the lifting carrying of material, generally all carry out lifting mobile, because the material ratio of lifting is heavier, arm needs to bear larger pressure, for some telescopic arms, arm can stretch out very long, during lifting material, need arm to bear larger pressure, damage is caused to arm.
Summary of the invention
In order to solve the problem, the utility model provides a kind of adjustable support of crane arm, and it can realize the support of different arm easily, alleviates the load-bearing pressure of arm, ensures excellent support effect.
Its technical scheme is such: a kind of adjustable support of crane arm, it is characterized in that, it comprises base, described base lower end mounting foot, described base installs support cylinder, the piston rod of described support cylinder installs supporting seat, described supporting seat upper end is semi-round brace table, described brace table arranges sliding seat, described brace table has arc-shaped slot, the slide block coordinated with described arc-shaped slot is installed bottom described sliding seat, described slide block inlay card is in described arc-shaped slot, described sliding seat both sides connect two strut bar one end respectively, two described strut bar other ends connect S. A. respectively, described S. A. is installed on described supporting seat, sprocket wheel is installed in described S. A. one end, drive motor is installed in described supporting seat side, the motor shaft of described drive motor installs drive wheel, described drive wheel is connected by chain drive-belt with described sprocket wheel, described sliding seat has arm and lays draw-in groove.
It is further characterized in that, described lower margin has tapped bore installation fixed orifice, to unthreaded hole, fixed orifice pair is installed, described tapped bore is installed fixed orifice and is installed fixed orifice to diagonally arranging respectively to, unthreaded hole, and described lower margin is installed the right screw thread fit of fixed orifice and setscrew and described unthreaded hole by adjustment screw and described tapped bore and installed the right cooperation of fixed orifice and install and be connected ground;
Described arc-shaped slot opening radian is 60 degree to 80 degree;
Described arc-shaped slot two ends are mounting limit block respectively;
Even mounting arrangements four described support cylinders on described base;
Described sliding seat one end symmetry installs two pieces of auxiliary support plates, and two pieces of described auxiliary support plates are fixedly connected with two spring one end respectively, and two described spring other ends are fixedly connected with described supporting seat respectively, and described spring is in compressive state.
After adopting structure of the present utility model, drive motor works, drive sprocket rotation by chain drive-belt, make sliding seat in arc-shaped slot, move to the suitable position of putting of arm, suspension arm support is laid on draw-in groove in arm, for arm is played a supporting role, effectively alleviate the load-bearing pressure of arm, the piston rod of support cylinder drives supporting seat to move up and down, to adapt to different arm, enable arm and arm lay draw-in groove to fit tightly, ensure excellent support effect.
