Ground, can be set 4 groups of guiding mechanisms, and 4 groups of guiding mechanisms centered on elevating mechanism, can be distributed in the corner of base 21.
In use, the range section according to needed for test, rotation and the height of rotary elevating platform 3 are controlled so that required
The top of suspension hook 7 of the one piece of counterweight in the top of one group of counterweight is slightly above the bottom of claw hook 1, and sideways through the groove of the lower end of claw hook 1
Mouth enters claw hook 1.Then decline pallet 4, the counterweight on pallet 4 also declines therewith, until the suspension hook 7 of the one piece of counterweight in the top is hung
Come on claw hook 1.So just complete the loading of first piece of counterweight.Continue to decline pallet 4, counterweight also declines therewith, every piece of weight
The hanger 8 of code slings the bearing pin 9 of next layer of counterweight, and next layer of counterweight is sling, every piece of counterweight is loaded into last layer successively
On counterweight, until all loading is got on by required counterweight.The height for controlling pallet 4 to decline, can control loaded weight
The number of code.During unloading, rising pallet 4, each counterweight in counterweight group 2 is added on pallet one by one, one piece of the top counterweight
Suspension hook 7 deviate from the notch of the lower end of claw hook 1, until recover as former state.
Compared with prior art, the beneficial effects of the invention are as follows the automatic loading that large-scale counterweight can be achieved, meet that standard is turned round
The counterweight of moment device loads demand automatically.Meanwhile limit function is carried according to the counterweight automatic loading device of the present invention, make counterweight
Loading is more stable, and can recover initial position after unloading.
Specific example used herein is set forth to the principle and embodiment of the present invention, and above example is said
It is bright to be only intended to help the method and its core concept for understanding the present invention；Meanwhile for those of ordinary skill in the art, foundation
The thought of the present invention, there will be changes in specific embodiments and applications, in summary, this specification content is not
It is interpreted as limitation of the present invention.
