As further technical scheme of the present utility model: at this based in hyperacoustic slump measuring instrument, described support bar is provided with the scale indicating height.
Further technical scheme: at this based in hyperacoustic slump measuring instrument, described sleeve sets firmly an extension board, extension board is provided with vertical threaded hole, this vertical threaded hole assembling one vertical screw mandrel, in the bottom of described support bar, one fixed head is set, this fixed head is provided with vertical unthreaded hole, and the bottom of described vertical screw mandrel is passed this unthreaded hole and arranges stopper in the below of fixed head.
Further technical scheme: at this based in hyperacoustic slump measuring instrument, the upper end of described vertical screw mandrel is provided with operating handle.
The beneficial effects of the utility model are: this kind can easily measure the true altitude after Control Measures for Concrete Slump based on hyperacoustic slump measuring instrument, when when avoiding measurement, peak chooses inaccurate or reading, sight line does not just cause measuring error, ensure that the accuracy of measurement.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is the schematic diagram of concrete slump detection method in prior art;
Fig. 2 is the structural representation of the utility model embodiment;
Fig. 3 be Y-direction guide rail in Fig. 2, Y-direction draw runner A to schematic diagram (amplification);
In figure: 1 slump cone, 2 base plates, 3 support bars, 31 scales, 4 sleeves, 5 trip bolts, 6X direction guiding rail, 7X is to tooth bar, 8 driven wheels, 9 gear supports, 10X is to driving crank, 11Y direction guiding rail, 12Y to draw runner, 13 ultrasonic scanning distance measuring equipments, 14 convexes, 15Y is to screw mandrel, 16 stoppers, 17 extension boards, 18 vertical screw mandrels, 19 fixed heads, 20 stoppers, 21 operating handles, 22 concrete collapsed.
Embodiment
As shown in Figure 2,3, slump cone 1, base plate 2 should mainly be comprised based on hyperacoustic slump measuring instrument.
The side of base plate 2 arranges a support bar 3, support bar 3 is provided with a sleeve 4, sleeve 4 is provided with the trip bolt 5 for the position of fixed muffle 4 on support bar 3.
Side arranges an X direction guiding rail 6 on a base plate 2, assembling one X be slidably matched in X direction guiding rail 6 is to tooth bar 7, the driven wheel 8 coordinated to tooth bar 7 with X is supported on a gear support 9 by gear shaft, gear support 9 is packed on X direction guiding rail 6, and the gear shaft of described driven wheel 8 connects an X to driving crank 10.
Described X connects to the below that tooth bar 7 coordinates with Y-direction guide rail 11, as shown in Figure 3, slidable fit one Y-direction draw runner 12 in Y-direction guide rail 11, ultrasonic scanning distance measuring equipment 13 is fixed with bottom Y-direction draw runner 12, one end of described Y-direction draw runner 12 arranges a convex 14 upwards, this convex 14 arranges a Y-direction unthreaded hole, a Y-direction screw mandrel 15 is provided with in this Y-direction unthreaded hole, a threaded hole is provided with in described Y-direction guide rail 11, the front end of described Y-direction screw mandrel 15 coordinates with this threaded hole, and the rear end of Y-direction screw mandrel 15 is positioned at the rear of convex 14 and is provided with stopper 16.
