Description
Technical Field
The utility model relates to the technical field of bridges, in particular to an intelligent force-measuring type bridge support.
Background
The bridge support is an important functional connecting piece of a bridge structure and mainly plays a role in releasing bridge deformation and transferring load on the upper part of a bridge.
Generally, a bridge needs to be provided with 4 or more bridge supports. Namely, the bridge belongs to a statically indeterminate structure. When the bridge is designed, theoretical calculation is firstly carried out: calculating the self weight (static load) of the bridge, and estimating the dynamic load of the upper part, wherein the sum of the static load and the dynamic load is the total load of the bridge. During theoretical calculation, the upper load is generally uniformly distributed on each bridge support, but the statically indeterminate structure is difficult to ensure that each support is uniformly stressed.
If each support is added with the function of automatically detecting the actual stress, the difference between the actual condition and the theoretical value can be calculated by comparing the observed data with the theoretical data, and the health condition of the bridge structure can be judged by analyzing the difference. If the difference is beyond a certain range, other measures can be adopted to reduce the difference.
For some bridges with special structures, such as a cable-stayed bridge or a suspension bridge, the reaction force and the change of a main bridge support are monitored, the conditions of looseness and beam stress of a long stay cable controlled by the support can be directly measured and calculated, and an auxiliary basis is provided for establishing maintenance measures of a bridge stay cable and a main beam.
There are also bridges that must be built on these complex geological structures. These complex geology may be hard rock or soft gravel or quicksand. Although necessary reinforcement treatment can be carried out on the soft gravel or the quicksand foundation, the foundation subsides and displaces in actual use, and pier deflection is caused, so that the bridge cannot be normally used or even collapses, and therefore the bridge support needs to be subjected to force measurement to ensure the safety of the bridge support.
Therefore, an intelligent force-measuring bridge support is designed according to the technical problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims to: in order to solve the problem that the bridge support in the prior art cannot monitor the force measurement without a dynamometer, the utility model designs an intelligent force measurement type bridge support.
The utility model specifically adopts the following technical scheme that the intelligent force-measuring bridge support comprises a piston and a base which are sequentially arranged from top to bottom, a plurality of disc spring assemblies are arranged in the base, a displacement sensor is arranged between the piston and the base and electrically connected with a data terminal, a metal guide rod penetrates through the middle part of each disc spring assembly, the base is of a steel basin structure, the middle of the piston is of a raised circular structure, the raised circular structure is matched with the inner diameter of the steel basin in size, and a plurality of round holes matched with the metal guide rod are formed in the raised circular structure of the piston.
Further, the belleville spring assembly is formed by combining a plurality of belleville springs, so that the belleville spring assembly can bear a load in a wider test range.
The working principle is as follows: this application upper portion load is loaded in the top surface of piston, and the piston transmits power for belleville spring subassembly, and belleville spring subassembly receives vertical load compressive deformation, and metal guide arm makes belleville spring subassembly regular displacement when compressive deformation, then this deformation simultaneously reaction is on arranging the displacement sensor between piston and steel basin, from the size of reacting upper portion load through warping to show through data terminal.
