Detailed description of the invention
In order to further instruction superiority of the present utility model, performance of the present utility model is carried out to the test of different pieces of information:
First group: adopt identical work copper coin and backboard, the version adopting the utility model not arrange tension rope is respectively fixedly connected with bolt, respectively test job copper coin and relative horizontal and vertical displacement and the service life that can produce between backboard, the experimental data of acquisition is as shown in the table:
| Title | Relative lateral displacement | Opposed vertical displacement | Service life |
| The utility model | 5-8mm | 2-4mm | 15-16 ten thousand tons |
| Set bolt structure | 0.1-0.5mm | 0.05-0.09mm | 8-9 ten thousand tons |
| Do not adopt the utility model structure of tension rope | 3-5.5mm | 1-2.5mm | 11-12 ten thousand tons |
Note: the data that this group experiment test is test 200*240 millimeter corrosion resistant plate, 900*20 steel plate obtains, carries out testing the average range value obtained to 200 complete equipments continuously.
Produce in the corrosion resistant plate of 200*240 and the continuous cast mold of 900*20 steel plate although adopt identical copper plate of crystallizer to be all applied in as can be seen from the above table, continuously produce acquisition mean values through 200 complete equipments can find out, the utility model not only possesses well lateral displacement and opposed vertical displacement relatively, and service life is also very long, and when the utility model does not adopt tension rope structure, what it obtained is relatively laterally only of the present utility model about 50% with vertical displacement, can find out only under the synergy of this device elastic module and tension rope, just obtain this device and possess splendid practical function.
Second group:
Adopt identical elastic module arrange tension rope respectively and do not arrange tension rope, measuring unit area (1 square metre) work copper coin obtains same intensity, and then detect the probability that single nut loosening lost efficacy, the data of acquisition are as follows:
| Title | Bolt quantity | The quantity of inefficacy bolt |
| Tension rope is set | 60～70 | 0 |
| Tension rope is not set | 80～90 | 1-2 |
Note: this group experiment test 200 times, experiment adopts the copper plate of crystallizer of 200*240 millimeter corrosion resistant plate, 900*20 steel plate, the average data that the closely-pitched Steel Bolt of what its bolt adopted is M16/M12 obtains.
As can be seen from the above table when not arranging tension rope, in order to ensure work copper coin and produce relative horizontal or vertical displacement between backboard, and ensure the quality of locking, often apply suitable pretightning force, ensure can not loosening of bolt top nut, but because production environment is severe and copper coin makes to cause the uncertain factors such as elastomeric material inefficacy after locally bolt bears very large pressure by the factor of thermal deformation, cause loosening, thus by point to face, reacted to overall qualitative change by local, then production safety can be had a strong impact on, simultaneously in order to ensure that the more bolt of security setting is fixed, and the utility model adopts and to be applied with an outside pulling force on bolt top again, even if nut loosening elastic module lost efficacy, also can the relative displacement that this bolt place produces be transferred on tension rope, and by carrying out through it disperseing on other bolts on same tension rope, its security being that acts synergistically obtains great lifting.
