Abstract
The utility model provides an electrodynamometer support structure which is characterized by comprising a bottom basin, plugs, copper wires with power lines and resistance wires, rubber plates, metal boxes with strain gages and a middle steel plate. The strain gages are arranged in the metal boxes, the metal boxes are led out through the copper wire with the power line and the resistance wire, two metal boxes are correspondingly arranged on each support, the two metal boxes are symmetrically vulcanized on the rubber plate corresponding to the support, two small holes are symmetrically arranged on the middle steel plate and the bottom basin of the support, corresponding copper wires penetrate through the small holes and penetrate out of the support, and two plugs corresponding to the two small holes are arranged outside of the small holes of the bottom basin. By means of the design, the electrodynamometer support structure can reduce processing manufacturing difficulties of a hydraulic system and reduces difficulties in hydraulic dynamometry. The electrodynamometer support structure is simple to operate. An operator only needs one screwdriver, a power supply (a dry battery) and a dynamometer to be on a bridge.
Description
Technical field
The utility model relates to a kind of novel electrical measurement power bearing.
Background technology
China is vast in territory, complicated geological configuration.And some bridges must be built on these complicated geological structures.These complex geological conditions may be hard rocks, also may be soft gravel or drift sands.According to incompletely statistics, counted from 2007, over 5 years, the whole nation has 37 bridge blocks and collapses, and causes altogether 182 people to die, and 177 people are injured.Wherein Hunan Pingjiang Yong Guqiao and the ferreous western bridge in Heilungkiang are identified as with flood erosion and cause that the pier footing position comes to nothing relevant.Come to nothing in the basis, Settlement and displacement, causes the bridge pier Lack of support, causes bridge to collapse.Famous exactly Guangdong Jiujiang Bridge is collapsed, though by the ship bump direct relation is arranged with bridge, post-survey, this accident is also relevant with bridge pier bottom foundation settlement.As seen, build at this geologic bridge and need to have special measure to deal with the generation of this situation.
At present, domestic Dynamometric support mainly adopts fluid pressure type, namely in the rubber tile of bearing hydraulic cavities is set, and is connected with dynamometer.The weak point of this method is to adopt hydraulic system, and manufacturing cost increases, and maintenance difficulties increases, so need to be improved.
The utility model content
The purpose of this utility model is to provide a kind of cost lower at this, safeguards novel Dynamometric support easy to use.
] the utility model is achieved in that a kind of electrical measurement power seat structure of structure, it is characterized in that: include end basin, plug, the copper cash with power line and resistance wire, rubber tile, with metal box and the middle steel plate of foil gauge; Described foil gauge places in the metal box, the metal box is used with the copper cash connection of power line, resistance wire and is drawn, wherein each bearing correspondence arranges 2 metal boxes, the symmetrical sulfuration of described two metal boxes is on rubber tile corresponding to bearing, the middle steel plate of described bearing, end basin are symmetrical arranged two apertures, and the copper cash of correspondence is penetrated aperture and passes the bearing outside; Two plugs corresponding with aperture of outer setting at end basin aperture.
The beneficial effects of the utility model are: adopt the described electrical measurement power of the design seat structure can reduce on the one hand the processing and manufacturing difficulty of hydraulic system, can also reduce on the other hand the difficulty of hydraulic pressure dynamometry (during hydraulic pressure Dynamometric support dynamometry, need to connect first hydraulic dynamometer, then unclamp hydraulic selector.This process seems and uncomplicated, but under the working environment under high-risk (tens of rice high bridge pier on), the high pressure (hydraulic pressure strength is high), difficult operates).This operation relatively much more only to need a people be with screwdriver one that, power supply (can be a dry cell batteries) cover, dynamometer upper bridge are got final product.
Description of drawings
Fig. 1 is the utility model seat structure schematic diagram
Fig. 2 is Fig. 1 I section enlarged diagram
Among the figure: 1, end basin, 2, plug, 3, power line, 4, resistance wire, 5, rubber tile, 6, the metal box, 7, foil gauge, 8, middle steel plate.
The specific embodiment
1-2 is described in detail the utility model below in conjunction with accompanying drawing:
The utility model provides a kind of electrical measurement power seat structure by improving at this, and shown in Fig. 1-2: this bearing includes end basin 1, plug 2, power line 3, resistance wire 4, rubber tile 5, with metal box 6 and the middle steel plate 8 of foil gauge 7.Described foil gauge 7 places in the metal box 6, metal box 6 power lines 3 and resistance wire 4 connect draws, wherein each bearing correspondence arranges 2 metal boxes 6, described two metal boxes, 6 symmetrical sulfurations are on rubber tile 5 corresponding to bearing, the middle steel plate 8 of described bearing, end basin 1 are symmetrical arranged two apertures, and the copper cash of correspondence is penetrated aperture and passes the bearing outside; Two plugs corresponding with aperture 2 of outer setting at end basin 1 aperture.
In the utility model foil gauge 7 placed a special metal box 6(strain box of making) in, and draw the box outside with sufficiently long copper cash (enamel-covered wire comprises power line 3, resistance wire 4), as shown in Figure 1, each bearing arranges two metal boxes 6; 2 strain boxes symmetry is vulcanized on bearing rubber tile 5 place at preferably close edge, and the situation of drawing of attention copper cash; Middle steel plate 8, end basin 1 symmetry of bearing are respectively bored 2 apertures, copper cash is penetrated aperture and passes the bearing outside; At outer setting 2 plugs of end basin aperture, usually with plug copper cash is sealed up for safekeeping in aperture; During dynamometry plug is opened, copper cash connects respectively power supply and dynamometer, again seals power line 3 and resistance wire 4 after the electrical measurement up for safekeeping.
The vertical active force of bridge beam body passes to rubber tile by middle steel plate, and stress changed around any change of vertical force also affected the strain box, and passed to outside dynamometer by box internal strain sheet.Because this electric measuring method need to be switched on to foil gauge, therefore need to reserve circumscripted power line.
