Description
Technical field
The utility model relates to the suspender technical field, particularly a kind of balance crane lifting drive.
Background technology
At present, being seen balance crane has two kinds of mechanical balance crane and hydraulic balancing cranes on the market, and the lifting of hydraulic balancing crane drives and finishes by hydraulic efficiency gear, and the lifting driving of mechanical balance crane is finished by mechanical device.Complicated turbine, the endless screw apparatus of one cover arranged in the mechanical actuation device of mechanical balance crane.Although turbine, endless screw apparatus self-locking performance are good, the unloading when can actv. solving the balance crane hoisting heavy, for high-frequency lifting carrying workplace, frequently forward counter-rotating, turbine, worm screw wearing and tearing are very fast, use very inconvenient.
Summary of the invention
The purpose of this utility model is that a kind of balance crane lifting drive will be provided.
For achieving the above object, the utility model is implemented according to following technical scheme:
A kind of balance crane lifting drive, comprise electrical motor, transmission gearbox, the rotary screw that the setting of described transmission gearbox inner bottom part is captiveed joint with motor rotary shaft, rotary screw and electrical motor joint arrange oil sealing, the rotary screw top arranges the rotary screw stable bearing, described rotary screw bottom arranges lifting nut, be fixedly installed two blocks of stressed steel plates at lifting nut, stressed steel plate is passed stressed steel plate and be fixedly installed two lifting nut motion guide rods parallel with rotary screw in transmission gearbox by the jam nut locking that is arranged on the lifting nut top; Arrange two in the described transmission gearbox with the drive link of lifting nut up-and-down movement, two drive links are fixed on two blocks of stressed steel plates in the same manner, and the top of transmission gearbox is passed on the top of two drive links, described two drive link tops are fixedly installed balance crane arm connecting device, on the balance crane arm connecting device arm adapter shaft are set.
As further prioritization scheme of the present utility model, the lead angle of described rotary screw and lifting nut is all less than or equal to 4 ° 30 ".
Compared with prior art, the utility model balance crane actuating device, complicated turbine, endless screw apparatus have been removed, the direct driven rotary screw mandrel rotation of electrical motor, two blocks of stressed steel plates that make lifting nut and be fixed on the lifting nut are done vertical up and down movement along the guide rod that moves, the lead angle of rotary screw and lifting nut is less than or equal to 4 ° 30 "; have auto-lock function; thus both avoided unloading in the hoisting heavy process; also solved turbine, the worm screw wearing and tearing are very fast; use very inconvenient problem, simultaneously, reduced the production and processing cost.
