Embodiment
[0022] The fixtures used for model test installation and measurement in this embodiment are as follows: figure 1 As shown, a support platform 1, a positioning rod 13 and a support base 3 are included. Among them, the support table 1 is composed of two sub-parts in a plane concave shape, and the horizontal adjustment rods 11 arranged at equal intervals in the middle are connected to the two sub-parts to form a vertically hollow working space in the middle for placing the test chamber. A horizontal adjustment rod 11 is arranged in the middle of one side of the support platform, and the horizontal adjustment rod 11 is a circular rod with a circular opening on the shaft. The other side of the support platform is provided with vertical and horizontal circular holes in the middle, wherein the horizontal hole can be inserted into the horizontal adjustment rod 11, the vertical hole can be inserted into the horizontal adjustment rod fixing bolt 12, and the horizontal adjustment rod 12 ...

The invention discloses a fixing device used for mounting and measurement of model tests. The fixing device comprises a supporting platform, positioning rods and supporting bases; the supporting platform is provided with vertical and horizontal adjusting rods with holes at equal distances, and the height and the length of the supporting platform are controlled through vertical adjusting rod fixingbolts and horizontal adjusting rod fixing bolts respectively; the supporting bases are connected with the supporting platform through the vertical adjusting rods; rotating wheels and supporting baseplates are arranged at the bottoms of the supporting bases; the positioning rods and rulers on two sides are arranged in the middle of the supporting platform; and a model and measurement equipment are fixed on the positioning rods by the aid of a model fixing rod and an equipment fixing rod through fixing rod sleeves. The fixing device is applicable to model test boxes in different sizes throughadjustment of the inserting lengths of the vertical and horizontal adjusting rods; the positions of the positioning rods can be adjusted accurately, so that the accuracy of the fixing positions of themodel and the measurement equipment is guaranteed; and movement of the fixing device is facilitated by the rotating wheels of the supporting bases, and the overall stability during use can be guaranteed through sinking of the supporting base plates.
Description
technical field [0001] The invention belongs to the field of engineering indoor model tests, and relates to a device for installing a test model and fixing related equipment in a test stage, in particular to a fixing device for model test installation and measurement. Background technique [0002] Model test is a research method widely used at present. Compared with complex in-situ test, it has the advantages of low cost and good controllability. It is suitable for carrying out targeted parameter influence research and regularity exploration. As a highly comprehensive research method, it involves many aspects such as theory, installation, and measurement in the process of turning the design scheme into an actual test simulation. For example, in the model test in the field of pile-soil interaction in geotechnical engineering, it is often necessary to fix the pile foundation at a specific position during the installation process of the test, and then perform other follow-up wo...
