Detailed Description
In order to make the objects, technical solutions and advantageous effects of the present utility model more apparent, preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding of the skilled person.
As shown in fig. 1-2, the leveling device for precisely measuring the elevation of the pipeline in the inspection well comprises a vertical center vertical rod 1 and an adjusting bracket; the adjustable vertical central vertical rod 1 is rotatably and slidably nested in the adjustable bracket, the adjustable bracket is in an h-shaped structure as a central rotating shaft of the adjustable bracket, the material of the adjustable vertical central vertical rod 1 is not limited to galvanized steel pipes, the material of the adjustable bracket is not limited to PVC pipes, the adjustable vertical central vertical rod 1 and the adjustable bracket can be replaced by other materials, the adjustable bracket comprises an adjustable bracket long vertical rod 2, an adjustable bracket horizontal cross rod 3 and an adjustable bracket short vertical rod 4, the adjustable bracket long vertical rod 2 is sleeved on the adjustable vertical central vertical rod 1, the adjustable bracket long vertical rod 2 can slide up and down along the adjustable vertical central vertical rod 1 and can rotate for 360 degrees around the adjustable vertical central vertical rod 1, so that the position of the adjustable bracket horizontal cross rod 3 of the leveling bracket is adjusted, the horizontal cross rod 3 is slidably mounted on the adjustable bracket long vertical rod 2, the surface of the adjustable bracket horizontal cross rod 3 is mainly used for vertically placing a measuring tower ruler, the adjustable bracket short vertical rod 4 is vertically mounted at the end of the adjustable bracket horizontal cross rod 3, and the adjustable vertical rod measuring device is not only used for measuring a pipeline of a check well, but also can be used for measuring coordinates of other hidden positions in a similar situation.
The horizontal cross rod 3 of the adjusting bracket and the short vertical rod 4 of the adjusting bracket are of telescopic structures, the short vertical rod 4 of the adjusting bracket is shortened to zero, the adjusting bracket is of a T-shaped structure and is used for checking wells with different borehole diameter specifications, and the vertical center vertical rod 1 and the adjusting bracket can be lengthened or shortened to be used for measuring leveling devices for manufacturing checking wells with different depths.
