Abstract
The utility model belongs to lever hoisting apparatus's improvement, especially semi-circular track automatically regulated counter weight centrobaric hoisting apparatus, include and setting up fixed fulcrum at the middle part of lever, installing the counter weight in the one end of lever, its other end lifts by crane the heavy object, is articulating the connecting rod on the lever between fixed fulcrum and counter weight, is installing the crank on the motor drive's gearbox output shaft, and the crank tip is articulated with the lower extreme of connecting rod, and connecting rod upper end pin joint is convex lever track to the lever of installing counter weight one side, and the roll formula counter weight is being installed in the cooperation on convex lever track. The utility model discloses not only the jack-up effort is balanced, can automatically regulated counter weight focus, makes jack-up electric current steady, and is power consumptive few, improves the life of gearbox, and is small moreover, light in weight uses safe and reliable.
Description
Technical field
The utility model belongs to the improvement of lever hoisting device, particularly the hoisting device of semi-circular track automatically regulating counterweight center of gravity.
Background technology
The lever of the lever hoisting device of prior art is the linear pattern lever, middle part at lever is being provided with fixed pivot, one end captive joint of lever clump weight, its other end hoisting heavy, the articulated connecting rod of the jointed shaft that is provided with on the lever between fixed pivot and the clump weight, the crank that the lower end of connecting rod and electrical motor, change speed gear box drive is hinged.In the lifting process, because lever and ground-surface angle constantly change, the moment that makes lever is also in continuous variation, and application force overbalance in the lifting process is little when big when causing the electric current in the electrical motor, and is more serious to the gearbox gear damage.The volume of this hoisting device is big, and weight is big, and power consumption is many.
The utility model content
The purpose of this utility model is to provide a kind of hoisting device of semi-circular track automatically regulating counterweight center of gravity, and not only lifting application force equilibrium can automatically regulating counterweight center of gravity, make the lifting electric current steady, little power consumption, the service life of improving change speed gear box, and volume is little, and is in light weight, safe and reliable.
The purpose of this utility model is achieved in that a kind of hoisting device of semi-circular track automatically regulating counterweight center of gravity, the middle part that is included in lever is being provided with fixed pivot, end at lever is installed with counterweight, its other end hoisting heavy, articulated connecting rod on the lever between fixed pivot and the counterweight, on the output shaft of gear-box of electric motor drive crank is installed, the lower end of crank end and connecting rod is hinged, small end hinge-point to the lever that counterweight one side is installed is the circular arc lever track, cooperates the roller counterweight is installed on the circular arc lever track.
During the utility model work, drive change speed gear box by motor operation, output shaft of gear-box drives crank and rotates, and crank drives lever by connecting rod, and making lever is both sides, axle center up-and-down movement with the fixed pivot, is positioned at the circular arc lever track up-and-down movement of counterweight side.The roller counterweight that matches with the circular arc lever track, along with circular arc lever track up-and-down movement, the roller counterweight is high-end to the low side operation from the circular arc lever track, realizes reciprocal lifting.When the crank drivening rod moves downward, the lever that connecting rod drives the counterweight end rotates, this moment, the roller counterweight was moved from high to low along the circular arc lever track, when crank forwards to downwards when overlapping with connecting rod, this moment, the outer end of circular arc lever track was in nadir, and by the weight that the lifted by crane extreme higher position of being sling, the roller weight counterbalance operation stops to the low dot location of arc-shaped rail outer end.When crank drivening rod upward movement, the lever that connecting rod drives the counterweight end upwards rotates, when crank and connecting rod are in alignment up and down, this moment, the outer end of circular arc lever track was at the highest notch, and the weight that is lifted by crane is in extreme lower position, and the roller weight counterbalance operation stops to the height point position of circular arc lever track the inner.The crank drivening rod makes circular arc lever track up-and-down movement, and the roller counterweight is back and forth rolled along the circular arc lever track, and the center of gravity of automatically regulating counterweight realizes reciprocal lifting.The utility model has realized that in the lifting process lever counterweight end aligns the counterweight center of gravity automatically, make the lifting application force all steady, thereby the lifting electric current that reaches electrical motor is steady, little power consumption.Make the gearbox gear stress equalization, prolonged the service life of change speed gear box, and the utility model volume is little, in light weight, safe and reliable.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
A kind of hoisting device of semi-circular track automatically regulating counterweight center of gravity, as shown in drawings, the middle part that is included in lever 1 is being provided with fixed pivot 3, end at lever 1 is installed with counterweight, its other end hoisting heavy 2, articulated connecting rod 4 on the lever between fixed pivot 3 and the counterweight 1, on change speed gear box 8 output shafts of electric motor drive crank 5 is installed, the lower end of crank 5 ends and connecting rod 4 is hinged, connecting rod 4 upper end hinge-points to the lever that counterweight one side is installed is a circular arc lever track 15, cooperates the roller counterweight is installed on circular arc lever track 15.Circular arc lever track 15 is that semi-round rail constitutes by rail level, the roller counterweight is for being installed in the flute profile roller 13 on the bolster 11 by bearing 12, the rib 15 of its race symmetry matches with rail both sides driving surface, and weight box 9 is being hung by the hanger 10 of symmetry in the two ends of bolster 11.Clump weight or sandstone are installed in weight box 9.Make counterweight with sandstone, can gather materials on the spot, save metallic material.Circular arc lever track 15 is the groove shape track, and the groove shape track is an opening channel-section steel up.The heavy ball of roller counterweight for matching with the groove of groove shape track.In the outer end of circular arc lever track 15 backing pin 16 or block are being set.
