Have and positioning hole is provided with crane, crane, Pitot tube is passed through from positioning hole, and between embedded two pulleys.
Further, described platform is to be provided with 4 fixing holes on rectangle, platform, can be fixed platform by fixing hole.
Further, described support bracket fastened bottom is connected by bolt with platform, and braking is provided with described pulley
Handle.
Further, described positioning track is rectangle, and positioning track is provided with graduation mark, is put to the accurate Pitot tube that reads
Different height is put, the end of two positioning tracks is both provided with baffle plate, prevents crane from being come off from positioning track.
Further, described crane is rectangle, and the positioning hole periphery on described crane is provided with a circle expanding material；
Described positioning bore dia is slightly larger than Pitot tube diameter, and such expanding material can be by Pitot tube panelling.
Further, described Pitot tube is L-type standard pitot tube, and Pitot tube size works as lifting according to depending on use requirement
Pitot tube will be higher by crane certain distance when frame is located at baffle position, prevent fixed support from surveying wind speed generation to Pitot tube dry
Disturb.
The beneficial effect that the utility model is produced：The utility model device is simple, operation facility, with low cost, convenient solid
It is fixed to can also adjust Pitot tube height with dismantling, Pitot tube can be fixed in wind tunnel experiment room with the present apparatus and surveys wind speed, it is also possible to this
Device fixes Pitot tube in outdoor wind load test and surveys wind speed.

Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model is a kind of Pitot tube fixing device that wind speed is surveyed for wind load test, including two
Structure identical fixed support 1, two fixed supports 1 are staggered relatively trapezoidal, and the bottom of fixed support 1 is fixed by bolt 6
On the platform 2 of rectangle, the top of fixed support 1 is provided with pulley 7 provided with one section of horizontal segment in the end of horizontal segment.
As shown in Fig. 2 being provided with positioning track 8 on the horizontal segment of fixed support 1, crane 14 can be in positioning track 8
On vertically moved relative to platform 2.Positioning track 8 is provided with graduation mark 4, and skin support is determined by the graduation mark 4 on positioning track 8
The height that pipe 3 is adjusted.Fixing hole 5 is equipped with four angles of platform 2, platform 2 can be fixed by fixing hole 5.
It is the partial enlarged drawing in Fig. 1 at A as shown in Figure 3.The end of positioning track 8 is provided with baffle plate 10, prevents crane
14 deviate from when being moved to 8 end of positioning track.Positioning hole 9 is provided with the middle part of crane 14, Pitot tube 3 passes through positioning
Hole 9.
It is the partial enlarged drawing in Fig. 1 at B as shown in Figure 4.Pitot tube 3 is embedded between two pulleys 11.In pulley 11
Brake handle 12 is provided with, after the height of Pitot tube 3 is adjusted, brake handle 12 is inserted in the gear of pulley simultaneously, made
Pulley is fixed, so that Pitot tube 3 is fixed on the height of determination, and crane 14 can also rest on some position simultaneously,
It will not slide downwards.
As shown in figure 5, being provided with expanding material 13 on the positioning hole 9 of the crane 14 of rectangle, expanding material 13 is arranged on
Around positioning hole 9.The diameter of positioning hole 3 is more than the diameter of Pitot tube 9, and such expanding material 13 can be by the panelling of Pitot tube 9.
