Detailed Description
The following detailed description of the present invention will be made with reference to the accompanying drawings and examples.
As shown in figures 1-4, a measuring device for hydraulic engineering construction comprises a support frame, a calibrating device 1 arranged on the support frame, and a level 3 supported by the support frame and penetrating through the calibrating device 1, wherein the calibrating device 1 comprises a calibrating shell 13, a through hole is formed in the center of the top surface of the calibrating shell 13, a vertically downward shaft sleeve 2 is arranged in the through hole, a plurality of threaded holes are uniformly formed in the circumference taking the axis of the shaft sleeve 2 as the center of circle on the bottom surface of the calibrating shell 13, supporting screws 5 are in threaded fit in the threaded holes, a hinge seat 6 is connected to the bottom of the supporting screws 5, an adjusting nut 4 in threaded fit with the supporting screws 5 is arranged on the supporting screws 5 below the calibrating shell 13, a hack lever 10 is hinged to the bottom of the hinge seat 6, one side of the hack lever 10 is grooved along the axis, a spherical sliding block 12 is arranged in the groove, the surface of, the top of the bottom plate 11 is provided with a spherical top block 9, the bottom of the level 3 is connected with a mandril 7 which is vertical to the level and passes through the shaft sleeve 2 to be in surface contact with the top block 9, a support 17 is horizontally arranged in the calibration shell 13, and the top of the support 17 is horizontally provided with an infrared level meter 18.
The embodiment of the utility model provides a concrete implementation does: at first open hack lever 10, make the support frame can support the device wholly, start infrared level meter 18, observe infrared level meter 18 and penetrate the infrared ray on projection board 16, when the reticle difference on infrared ray and projection board 16 is great, adjustment hack lever 10, adjust the horizontality of bottom plate 11, when the reticle on infrared ray and projection board 16 is close, through rotating adjusting nut 4, adjust the height of alignment shell 13, finally make infrared ray and reticle coincidence, the sight level that sees through surveyor's level 3 this moment, when using surveyor's level 3 to measure, when making surveyor's level 3 no longer horizontal because of the touching, infrared level meter 18 can send the warning because out of not horizontal, suggestion operating personnel carry out device level control, realize the horizontal real-time supervision of surveyor's level 3.
As shown in fig. 2, the calibration housing 13 is a transparent housing, and a projection plate 16 with a horizontal reticle is mounted on a side wall of the calibration housing 13 in a light irradiation direction of the infrared level 18; it is convenient to adjust the level of the infrared level 18.
As shown in fig. 1, the bottom end of the top rod 7 is hemispherical; on the premise of ensuring the support, the friction between the ejector rod 7 and the ejector block 9 is reduced.
As shown in fig. 2, a gasket 14 for buffering is arranged between the adjusting nut 4 and the bottom surface of the calibration housing 13; friction between the adjusting nut 4 and the calibration housing 13 is avoided.
