The compressive stress borne by the rubber pad is about 25MPa to 30MPa, when the bridge does not rotate, the vertical compressive stress is distributed more uniformly, but when the upper beam body rotates, the middle steel plate of the basin-type rubber support is pushed to rotate, the rubber pad can be subjected to a more obvious bias action, and the local compressive stress is larger. And the corner of the basin type support is generally designed to be 0.025, so that the situation that the local stress is overlarge due to the bias pressure often applied to the rubber pad is very prominent, and the stress of the steel basin and the uniform transmission of vertical load are not facilitated. Great hidden danger exists for the structures of the support and the bridge.
In order to solve the problem, the bottom basin of the basin-type support is designed to be stronger and the manufacturing cost is higher. Particularly, the dynamic load of the railway support is large, the frequency of the corner of the bridge is also high, and the fatigue performance of the material under repeated loading and bias pressure is very critical. The invention aims to solve the problem of rotational bias of the existing basin-type support, and adopts a new material which is similar to a liquid substance and has reliable transmission on the compressive stress, so that the compressive stress is still uniformly transmitted when the support rotates. Not only the existing function of the support is maintained, but also the problem of local bias is solved. The structural strength surplus caused by excessive local compressive stress resistance can be reduced, and the manufacturing cost is obviously reduced. On this basis, can arrange pressure sensor in the bottom basin of support optional position or in rubber pad inside, the inside compressive stress that vertical load produced is surveyd to the accuracy, realizes can focusing on the accurate control of atress situation.

Detailed Description

Any feature disclosed in this specification may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.
The rubber pad for a pot support and capable of accurately measuring force and the pot support thereof of the present invention will be described in detail below.
According to the illustrative embodiment of the invention, the rubber pad used for the pot type support and capable of accurately measuring the force comprises 90-110 parts of natural raw rubber or synthetic rubber, 4-7 parts of zinc oxide, 1-3 parts of stearic acid, 10-30 parts of carbon black, 0-5 parts of sulfur, 2-5 parts of an accelerator, 2-5 parts of an anti-aging agent, 10-50 parts of a plasticizer and 0-10 parts of a processing aid.
Wherein, the accelerator can be at least one of DM, Cz, NA-22 and EM-35, the anti-aging agent can be at least one of 4010NA, RD, ODA and paraffin, the plasticizer can be at least one of engine oil, DOP and paraffin oil, and the processing aid can be at least one of CR-X, magnesium oxide and HVA-2. The above substances are all commercially available.
The production process of the rubber pad can adopt the general process of the existing molded rubber product. Specifically, the raw materials are mixed, preformed, molded and vulcanized to directly prepare the rubber gasket with the required size or machine-processed and molded into the rubber gasket with the required size. Wherein the vulcanization temperature is controlled to be 130-150 ℃, the vulcanization pressure stress is not less than 10MPa, and the vulcanization time is 1-10 h.
The rubber pad prepared by adopting the raw materials, the formula and the process has the IRHD hardness of 20-40, the tensile strength of not less than 15MPa, the elongation at break of not less than 600 percent, and other properties meeting the relevant requirements of the basin-type support.
The rubber pad prepared by the invention is arranged between the bottom basin and the middle steel plate of the basin-type support, and the bottom of the rubber pad is provided with a plurality of pressure stress sensors or the pressure stress sensors are implanted into the rubber pad during vulcanization. Because the high polymer material with lower hardness is adopted to replace the pressure-bearing rubber pad of the existing basin-type support at about IRHD60 degrees, the material with lower hardness (the IRHD hardness is 20-40) can transmit pressure more uniformly, particularly, when the support rotates, local stress is not too large due to unbalance loading of the pressure-bearing rubber pad, and simultaneously, after the hardness of rubber materials is reduced, the internal stress is reduced, so that the support rotates more smoothly.
And the pressure sensors for measuring force can be arranged on the bottom wall, the side wall and/or the bottom of the middle steel plate of the bottom basin and the inside of the rubber pad, and because the pressure-bearing rubber pad made of the novel hardness material has uniform pressure stress transmission in all directions, the pressure stress measured by the sensors arranged at any positions is consistent, and the vertical pressure can be simply and accurately measured regardless of whether the support rotates or not.
Fig. 1 shows a schematic structural view of a basin-shaped support capable of accurately measuring force according to the present invention (a pressure stress sensor is disposed outside a rubber pad), and fig. 2 shows a schematic structural view of a basin-shaped support capable of accurately measuring force according to the present invention (a pressure stress sensor is disposed inside a rubber pad).
As shown in fig. 1 and 2, the basin-type support capable of accurately measuring force in the present invention includes a bottom basin 1, a middle steel plate 2, a rubber pad 3 and a pressure sensor 4, wherein the rubber pad 3 is disposed between the bottom basin 1 and the middle steel plate 2, and the pressure sensor 4 is disposed on the bottom wall, the side wall of the bottom basin 1 and/or the bottom of the middle steel plate 2 or inside the rubber pad, wherein the rubber pad 3 is the above-mentioned rubber pad.

Other accessory and derivative structures such as upper slide members, seal members for pressure pads, etc. are not shown (not shown).
This basin formula support is when the atress, and when middle steel sheet 2 received superstructure's vertical load, pressure can transmit the pressure-bearing on rubber pad 3, through rubber pad 3, on pressure can transmit bottom surface and the lateral wall of end basin 1, vertical power rethread end basin 1's bottom transmits the bed stone to the pier, accomplishes vertical power transmission. The rubber pad 3 plays a role in buffering and vibration reduction and is suitable for the rotation of the middle steel plate driven by the rotation of the beam body, and the rotation angle reaches 0.025 radian. When the basin type support rotates, the rubber pad 3 can uniformly transmit the compressive stress to the inner wall of the basin cavity, including the bottom and the side wall of the bottom basin, due to the uniform characteristic of the compressive stress in each direction, and the stress is uniform and the bias phenomenon cannot be generated. And the internal pressure obtained by the pressure stress sensor 4 which is arranged at any position in the pelvic cavity or implanted in the rubber pad is uniform and accurate no matter whether the support rotates or not.
Therefore, the invention can ensure that the load transfer of the upper structure of the basin-type support is more uniform and reliable, the local stress concentration can not be generated when the bridge body rotates, and the force transfer of the low-hardness rubber pad is uniform in all directions, so that the force measurement of the support is more accurate.
