Abstract
The utility model discloses a vertical displacement's testing arrangement at bottom of bridge, including steel sheet, pull ring, fixed pulley, weight, displacement meter and indium steel wire, the central point on steel sheet surface puts and is equipped with the pull ring, and the one end and the pull ring of indium steel wire are connected, and the weight is connected to the other end, is equipped with the displacement meter in the below of weight, passes through the fixed pulley in the middle of the indium steel wire. The utility model discloses simple structure measures conveniently to can make non professional use.
Description
Technical field
This utility model relates to a kind of measurement apparatus, is specifically related to the test device of vertical displacement at the bottom of a kind of bridge.
Background technology
Bridge static loading test, it is by static load action appointment position on bridge, then the parameters such as the static displacement of bridge structure, static(al) strain, crack are tested, thus a kind of loading test that bridge structure service behaviour under load action and use ability are made an appraisal.Static test be Test on Bridge Loading employs up to, modal fundamental test.
In the process doing bridge static loading test, for the measurement of vertical displacement at the bottom of bridge, this utility model provides a kind of simple, easy, safety, convenient measuring method, it is possible to accurately record vertical displacement at the bottom of bridge, guarantees the personal safety of on-the-spot testing crew simultaneously.
Utility model content
A kind of purpose of the present utility model is to provide the measurement apparatus of a kind of simple, safe ready, it is possible to records vertical displacement at the bottom of bridge accurately, also ensures that the safety of testing ground staff simultaneously.
The technical solution adopted in the utility model is: the test device of vertical displacement at the bottom of a kind of bridge, including steel plate, draw ring, fixed pulley, weight, displacement meter and indium steel wire, the center of surface of steel plate is provided with draw ring, one end of indium steel wire is connected with draw ring, the other end connects weight, at the displacement meter that is connected with of weight, in the middle of indium steel wire, pass through fixed pulley.
Further, the placement location of described steel plate is higher than fixed pulley.
Further, described indium steel wire is provided with scale.
This utility model produces to provide the benefit that: this utility model simple in construction is measured convenient, and layman can be made to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the schematic diagram of reinforcement point in this utility model；
Fig. 3 is the calculating figure measuring displacement.
Detailed description of the invention:
Below in conjunction with accompanying drawing, this utility model is further described.
As shown in Figure 1, the measurement apparatus of vertical displacement at the bottom of a kind of bridge, including steel plate 5, draw ring 7, fixed pulley 1, weight 2, displacement meter 3 and indium steel wire 4, the center on steel plate 5 surface is welded with draw ring 7, one end of indium steel wire 4 is connected with draw ring 7, the other end connects weight 2, is connected with displacement meter 3 at weight 2, by fixed pulley 1 in the middle of indium steel wire 4.
When measuring vertical displacement bottom bridge, first not affecting under the premise of original bridge capacity for guarantee, as in figure 2 it is shown, heart place seccotine 8 and steel plate 5 consolidate first in the target, and steel plate 5 processes through polishing.Draw ring 7 is connected with draw ring 7 by zero end with graduated indium steel wire 4, the other end of indium steel wire 4 is connected with weight 2, read respectively with protractor indium steel wire be further applied load before and after with the angle α of horizontal plane, β, as shown in Figure 3, read indium steel wire reading respectively l, l', measuring displacement meter reading is Δ l, then the vertical displacement bottom bridge is d:
Δ l=l-l'
D=l × sin α-l' × sin β
By displacement meter reading Δ l, and indium steel wire reading l, l', it is respectively compared, can as the check of result of calculation.Calculated by the derivation of above equation, vertical displacement at the bottom of bridge can be obtained.
