Foot loads the requirement of counterweight, namely on the premise of the overall length of spring 4 does not increases, it is possible to counterweight ratio
The twice situation of original load value, the loading range of this adaptation increases along with the quantity of movable pulley and increases
Adding, if any two movable pulleys, adaptable load value can increase to 4 times of original value；If any three
Movable pulley, the most adaptable load value can increase to original 6 times.Certainly, along with movable pulley quantity
Increase, construction weight and the complexity of assembly pulley 6 can be increased, steel wire rope 5 and pulley can be increased simultaneously
The frictional resistance of group 6, therefore optimized pulley block structure is advisable with 2 movable pulleys.
Preferably, the lower section of described cone pulley frame 32 is provided with fixed block 8, and described fixed block 8 is by a tune
Joint bolt 9 is connected with cone pulley frame 32, and it is certain that the load connection end of described steel wire rope 5 is wrapped in cone pulley 31
The number of turns, then walk around fixed pulley 61, movable pulley 62 successively, finally it is fixed on fixed block 8.By fine setting
Regulation bolt 9, mobile fixed block 8, finely tune the start position of steel wire rope 5 with this.
Preferably, described base 1 is turnable structure, and the spring 4 of counter weight device can be allowed around vertical
The axis of post 2 rotates, and adds the use flexibility ratio of whole counter weight device.
Preferably, being additionally provided with spring base 10 between described spring 4 and base 1, described spring base 10 leads to
Overregulate screw rod 11 to be connected with base 1, the tensile elongation of spring 4 can be pre-adjusted, it is ensured that carrying
Square and the equalising torque of spring 4 pulling force.
Preferably, described spring base 10 is connected with base 1 by least two adjusting screw rods 11, is possible to prevent
During regulation spring 4 length, the torsion that spring 4 self occurs.
Preferably, described spring base 10 is connected with base 1 by an adjusting screw rod 11, described column 2
Being provided with a chute extended along column 2 length direction at cavity, the side of described spring base 10 is provided with
The boss adaptive with chute.Use chute and the cooperation of boss, make spring base 10 move up and down along column 2,
Spacing to spring 4, can in the case of only adjusting screw rod 11, regulate spring 4 length and not
Twist displacement, so can alleviate the construction weight of counter weight device.
During spring balance device of the present utility model work, first cone pulley 31 is fixed, it is impossible to rotate, then
By adjusting screw rod 11 by spring 4 prestretched so that it is the spring energy of generation overcomes the weight of load.Regulate
After the pre-stretched length of spring 4, release the stationary state of cone pulley 31 so that it is can turn flexibly around step pulley shaft 33
Dynamic.Jacking load, whether sensation load weight reaches balance with the pulling force of spring 4, if uneven, can be again
Fine setting adjusting screw rod 11, reaches two ends balance.Further, jacking load, in whole stroke range,
Ensureing two ends balance, if having slight imbalance, fine-tuning regulation bolt 9 at extreme position, adjusting steel wire rope
