Description
Technical field
This utility model belongs to technical field of bridge, i.e. relates to a kind of dynamometry that can detect its bearing capacity in real time and heightens pot rubber bearing.
Background technology
Monitoring to bridge force-bearing, one of major measure being to ensure that bridge security.Bridge is by beam body, bridge pier and is arranged at bearing between the two and constitutes, and the geological state at most bridge places is complicated.All the time, the monitoring of bridge pad is mainly carried out by the method for traditional craft and range estimation, such as, check by simple tools such as telescopes, typically has to go to climbing stairs under bridge or uses the bridge monitoring car of height cost to detect.Owing to pier is higher, the clear space between Er Qieliang, plate and pier is the least, and monitoring is the most inconvenient, and has certain danger.The detection of bridge then more uses special equipment or bridge inspection vehicle to realize, and cost high workload is complicated, it is impossible to realize monitoring in real time.
Summary of the invention
The purpose of this utility model is just to provide a kind of by realizing the dynamometry of bridge force-bearing situation detection is heightened pot rubber bearing to the detection in real time of bearing bearing capacity.
Realizing this utility model above-mentioned purpose, the technical scheme used is:
A kind of dynamometry heightens pot rubber bearing, including the lower support plate being provided with pelvic cavity, formed seismic isolation and reduction structure be arranged in the pelvic cavity of lower support plate by upper bracket plate, spherical crown plate, middle steel liner plate, above-mentioned lower support plate is provided with the adjusting hole being provided with plug wire connected with pelvic cavity；The middle steel liner plate sidewall with pelvic cavity is provided with sealing ring, makes pelvic cavity be internally formed confined space；The bottom surface of described middle steel liner plate is provided with pressure-bearing rubber spacer, the solid matter just like paraffin or other low melting points is set in the space that lower support plate pelvic cavity and rubber spacer are formed；Arranging by least one barrel-shaped groove in described lower support plate pelvic cavity bottom, being fixed on pressure sensing mechanism therein connection has the induced signal line can being connected with external detection mechanism.
Constitute above-mentioned dynamometry to heighten the additional technical feature of pot rubber bearing and also include:
The bottom surface of the pelvic cavity corresponding with the adjusting hole that described pelvic cavity connects is provided with annular groove；
It is provided with heater block in described annular groove.
A kind of dynamometry provided by the utility model heightens pot rubber bearing compared with prior art, have the advantage that one, owing to arranging by least one barrel-shaped groove in the lower support plate pelvic cavity bottom constituting bearing, it is fixed on pressure sensing mechanism therein connection and has the induced signal line can being connected with external detection structure, therefore the force-bearing situation of bearing can be detected in real time by testing agency, it is simple to the monitoring to bridge；They are two years old, owing to the bottom surface of steel liner plate middle in constituting this bearing pelvic cavity is provided with rubber spacer, and in the space that rubber spacer is formed, it is provided with the solid matter of low melting point, therefore, it is possible to realize corner change and the function of height adjustment that bridge causes due to geological conditions or other stress effect, in order to the bearing being respectively provided with on balanced adjustment pier forms uniform load distribution to beam body.
Accompanying drawing explanation
Fig. 1 heightens pot rubber bearing structural representation for the dynamometry that this utility model provides；
Fig. 2 is the structural representation constituting above-mentioned bearing lower support plate.
Detailed description of the invention
Structure and use principle that dynamometry provided by the utility model is heightened pot rubber bearing below in conjunction with the accompanying drawings are described in further detail:
Special the heightening provided for this utility model as shown in Figure 1, 2 turns down the cross section structure schematic diagram of bearing.The structure constituting this bearing includes being provided with the lower support plate 2 of pelvic cavity 1, formed seismic isolation and reduction structure be arranged in the pelvic cavity 1 of lower support plate by upper bracket plate 3, spherical crown plate 4, middle steel liner plate 5, above-mentioned lower support plate is provided with the adjusting hole 7 being provided with plug wire 6 connected with pelvic cavity；The middle steel liner plate sidewall with pelvic cavity is provided with sealing ring 8, makes pelvic cavity be internally formed confined space；The bottom surface of above-mentioned middle steel liner plate is provided with pressure-bearing rubber spacer 11, the solid matter 10 just like paraffin or other low melting points is set in the space that lower support plate pelvic cavity and rubber spacer are formed；It is uniformly arranged by three (or four) barrel-shaped grooves 16 in above-mentioned lower support plate pelvic cavity bottom, is fixed on pressure transducer 13 therein and is connected with external detection mechanism 14 and has induced signal line 15.
The operation principle of this bearing is, by the pressure-bearing rubber blanket being arranged in pelvic cavity, and the multiple force cells arranged in the liquid height adjusting hole of pelvic cavity bottom and pelvic cavity bottom, the vertical pressure of pelvic cavity is measured by being fixed on the force cell of pelvic cavity bottom, i.e. vertical counter-force suffered by bearing, i.e. can determine that the real time load of bridge.
Wherein: S force cell measured area
Bottom sensor measures base pressure value
Base pressure value
The vertical counter-force of bearing
Sensor by data collecting module collected, analyze, process after, restore the size acting on bearing load, sensor external model testing agency, data model is sent to computer or mobile phone, monitor bridge load in real time, carry out data collection record based process abnormal accident.The most in use, the heating to lower support plate so that the solid matter 10 of low melting point in pelvic cavity, and released by adjusting hole, or it is added thereto to the solid matter 10 of low melting point by this adjusting hole, regulates the height of bearing, in order to adjust bridge and the stress of bridge pier；Ensure that vibration absorption and isolation support can effectively play a role.Can avoid construction error or the pier height of support that causes of sedimentation not, bias, the problem such as come to nothing.Can be used for monitoring Bearing Seat Force situation, the most convenient to use, save a large amount of manpower, financial resources, it is ensured that the use safety of bridge.Simultaneously because be provided with rubber spacer 11 in the bottom surface of middle steel liner plate, it is possible not only to directly carry the vertical loads of bridge, and due to the elastic characteristic being had of this rubber spacer, it is also possible to correct the corner deformation that bridge or bridge pier occur because of stress.
In the above-mentioned dynamometry of composition heightens the structure of pot rubber bearing,
The bottom surface of the pelvic cavity corresponding with the adjusting hole that described pelvic cavity connects is provided with annular groove 9, can be prevented effectively from when inside pelvic cavity, the solid matter 10 of injecting low melting point is heightened in filling, cause heightening auxiliary agent centre steel liner plate 5 is pushed up partially because of adjusting hole 7 heart position the most wherein, cause the generation of its displacement problem；
It is provided with heater block 12, in order to the heating and melting to the solid matter 10 of low melting point in above-mentioned annular groove 9.
