Abstract
The utility model provides an apparatus for measuring the cable fore of a bridge. The apparatus comprises a cable force sensor and a cable force sensor mounting pedestal. The cable force sensor is arranged to be of a magnetic stand integrated structure. A circular metal sheet is disposed on the cable force sensor mounting pedestal. The cable force sensor is fixed to the cable force sensor mounting pedestal via the circular metal sheet. The apparatus has a simple structure. A cable force sensor body and a magnetic stand are designed separately in the prior art, however, the cable force sensor and a magnetic stand of the apparatus are combined together in terms of structure, so that the magnetic stand is prevented from being mounted and dismounted repeatedly for each measurement. Therefore, the workload is saved and each measurement is more convenient.
Description
Technical field
The utility model relates to bridge survey device field, is specifically related to a kind of bridge cable force measurement mechanism.
Background technology
Along with the continuous expansion of national freeway net, the bridge that passes through great rivers is also more and more, for this Longspan Bridge, uses the mode of more cable-stayed bridge or arched bridge pre-stressed boom.Cable-stayed bridge and arched bridge pre-stressed boom are all stressed by cable wire, and king-tower (or steel arch) keeps the stable of bridge floor by cable wire.If the steel cable stretching force deficiency of bridge, easily produces bridge floor and tilt even to topple, cause serious accident.
In order regularly the health condition of cable wire to be checked, judge the size of Suo Li.General method is that vibration transducer is installed on Suo Li, records the vibration frequency of cable wire, uses vibratory drilling method to calculate the Suo Li of cable wire.
Due to cable wire thick (diameter 20cm left and right) conventionally, lack special Suo Li mounting tool, field engineering technician often feels simply helpless.
The mounting means of common cable tension sensor (IEPE type) has two kinds, and AB glue is gluing and magnetic support is bonding, and in bridge cable force test, AB glue is gluing because the needs time is long not too practical; Two magnetic supports are bonding, test forward and backwardly all magnetic support to be dismantled also pretty troublesomely at every turn, therefore design a force test device of rope simply and easily and seem very important.
Summary of the invention
The utility model is to solve the above-mentioned existing bridge cable force survey sensor of mentioning need to paste the problem of installing or installing by magnetic support, the bridge cable force measurement mechanism that provides a kind of sensor and magnetic support to be the integrated design, this bridge cable force measurement mechanism sensor is set to integral structure with installation magnetic support, easy for installation, simple in structure, easy to use, avoid each measurement all to need to install and dismantle the work of magnetic support.
Concrete, the utility model provides a kind of bridge cable force measurement mechanism, it comprises cable tension sensor and cable tension sensor mounting base, described cable tension sensor mounting base is flexible fiber cloth pedestal, described cable tension sensor comprises cable tension sensor body and magnetic support, described cable tension sensor is set to magnetic support integral structure, on described cable tension sensor mounting base, be provided with circular metal plate, described cable tension sensor is fixed on described cable tension sensor mounting base by described circular metal plate.
Preferably, the middle part of described cable tension sensor mounting base is provided with described circular metal plate.Described circular metal plate is iron-nickel alloy sheet metal.
Preferably, the two ends of described cable tension sensor mounting base are respectively arranged with bonding zone, and described two bonding zones magic tape each other, in the time that described cable tension sensor mounting base wraps up cable wire to be measured, by bonding its two ends compression.
The utility model is simple in structure, by original cable tension sensor body and the magnetic support of design respectively, structurally combines, and has avoided each measurement all to need to install and dismantle the work of magnetic support.Save workload, made each measurement convenient.
Brief description of the drawings
Fig. 1 is the structural representation of cable tension sensor mounting base of the present utility model;
Fig. 2 is the structural representation of cable tension sensor of the present utility model.
Embodiment
A kind of bridge cable force measurement mechanism, it comprises cable tension sensor 1 and cable tension sensor mounting base 2, and cable tension sensor 1 is set to magnetic support integral structure, and the middle part of cable tension sensor mounting base 2 is provided with circular metal plate 20.Circular metal plate 20 is iron-nickel alloy sheet metal.
Cable tension sensor 1 is fixed on cable tension sensor mounting base 2 by circular metal plate 20.
Cable tension sensor 1 comprises cable tension sensor body 10 and magnetic support 11, and cable tension sensor body 10 is designed to integral structure with pedestal 11.
It is flexible fiber cloth that cable tension sensor is installed 2, base.
The two ends of cable tension sensor mounting base 2 are respectively arranged with 21 and 22, two bonding zones 21 and 22 of bonding zone magic tape each other, in the time that cable tension sensor mounting base 2 wraps up cable wire to be measured, by bonding its two ends compression.
In use, with cable tension sensor mounting base 2, cable wire to be measured is wrapped, integrated magnetic support cable tension sensor 1 is adsorbed on the circular metal plate 20 in the middle of cable tension sensor mounting base 2, this process also only needs 1-3 second.
After measurement finishes, dismounting is also divided into conveniently, conventionally can dismantle complete second at 5-10.Be particularly suitable for the regular detection of each detection unit at large bridge cable wire, can reduce in a large number technician's working strength, increase work efficiency.
The utility model is simple in structure, by original cable tension sensor body and the magnetic support of design respectively, structurally combines, and has avoided each measurement all to need to install and dismantle the work of magnetic support.Save workload, made each measurement convenient.
Those skilled in the art will readily understand; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
