The corresponding corresponding weight of each main counterweight 11, is superimposed by multiple counterweights, realizes the load of the majority value, if you need to the weight of load
For 50kg, weight corresponding to each main counterweight 11 is 10kg, then needs to load the main weight of 5 above-mentioned 10kg on center sunpender 10
Code 11；
Ii. force standard machines are used as in use, need while loading main counterweight 11 and compensation weight 14, each block compensation counterweight
14 one piece of main counterweight 11 of corresponding compensation, the quality of compensation weight 14 meet formula:That is the main counterweight of 10kg
11 (and it is considered as g=9.8m/s2, the actually value of acceleration of gravity is local standard value),When needing to load the power of 200N, need to load 2
The main counterweight 11 of block, while loading 2 block compensation counterweights 14, it may be assumed that
(2) load of counterweight:
I. test specimen is loaded between the first fixed device 6 and the second fixed device 8, when loading main counterweight 11, by test specimen
It tenses；
Ii. the method for main counterweight 11 is loaded on center sunpender 10: under normal circumstances, by the first elevating mechanism by main weight
Code 11 is held up, at this point, main counterweight 11 and the first washer 18 are contactless, the power of main counterweight 11 is not loaded on center sunpender 10, when
When first elevating mechanism declines, main counterweight 11 is fallen on the first washer 18, and the gravitational load of main counterweight 11 is on center sunpender 10；
Iii. compensation weight 14 is loaded on center sunpender 10: being had on the centrally disposed sunpender 10 of part compensation weight 14,
Its principle is identical as the loading method of main counterweight 11；
Iv. part compensation weight 14 is arranged on auxiliary rod 26, and is concatenated into the by telescopic first connector
One counterweight group, second flap is arranged on auxiliary rod 26, and the second block is used to limit the compensation weight of most the first counterweight group top
Code 14 passes through, and when compensation weight 14 loads, by the elevating movement of the second elevating mechanism of the first counterweight group bottom, makes to pass through
The gravitational load of other compensation weights 14 of the first connector carry on top compensation weight 14 on auxiliary rod 26, and
The gravity of other compensation weights 14 by the support of the second elevating mechanism is not involved in counterweight in the second Sheng Jia mechanism；
V. the setting of part compensation weight 14 is concatenated into second on auxiliary rod 26, and through telescopic second connector
Third baffle is arranged on auxiliary rod 26 for counterweight group, and third block is used to limit passing through for the counterweight of the second counterweight group lowest part,
When compensation weight 14 loads, by the elevating movement of the third elevating mechanism at the top of the second counterweight group, part compensation weight 14
Gravity is applied to third gear on piece, participates in counterweight, part compensation weight 14 under the action of third elevating mechanism carry in third
On elevating mechanism, it is not involved in counterweight；
Vi. on the centrally disposed sunpender 10 of part compensation weight 14, principle is identical as the loading method of main counterweight 11.
Technical principle of the utility model has been described above with reference to specific embodiments.These descriptions are intended merely to explain this reality
With novel principle, and it cannot be construed to the limitation to scope of protection of the utility model in any way.Based on the explanation herein,
