Detailed Description
The present invention will be described in detail with reference to the following embodiments.
The invention provides an overhead man-vehicle installation measuring method, which is implemented by the following steps:
step 1, measuring and setting high-precision conforming wires in an auxiliary transportation roadway; the high-precision wire points in the conventional mine auxiliary transportation main roadway are seriously damaged, and the precision of temporarily reserved measuring points is insufficient, so that a high-precision closed wire is required to be measured again to ensure the reliability of a measuring result and avoid the influence on the design of the center of the roadway and the maintenance engineering quantity of the roadway caused by overlarge errors, and the result is used as the basis of the subsequent several-step measuring work;
step 2, measuring the width, height and fluctuation of the written roadway densely; typically, a dot is written every 5m to 10 m. The mine auxiliary transportation roadway is tunneled along a coal seam, the gradient changes frequently and irregularly, the mine auxiliary transportation roadway is influenced by mine pressure, and the deformation is serious, so that the maintenance design and the installation design of the overhead man car are ensured to be consistent with the actual design through intensive measurement and writing, the influence on the measurement efficiency due to the fact that the design is inconsistent with the actual design in the paying-off process is reduced, and unnecessary maintenance engineering quantity and problems in later-stage operation can be avoided;
and 3, calculating the position coordinates of the steel beams according to the design of the overhead man car, and calibrating the position of each steel beam by adopting a coordinate lofting mode. The step must adopt the umbrella wind-shielding method to ensure the alignment precision of the instrument;
step 4, calibrating a waist line according to the design, wherein the waist line calibrated on site must be compared with the design in the waist line calibration process to ensure that the overhead man pole is in accordance with the safety distance to the maximum extent and the lowest height can pass through the roadway bottom plate smoothly;
and 5, calibrating an installation center line of the overhead man car by the roadway top plate. The local forming of the arched tunnel during tunneling often does not meet the design requirement, so a central line point (the central line hanging error is large when the wind is large and the distance is long) must be calibrated at the top plate of the tunnel every 20-30m, the difference between the shoulder width of the arched tunnel and the design is convenient to check, and the design of a through steel beam or a short steel beam meets the actual requirement;
and 6, correcting the direction and the levelness of the steel beam. After the steel beam is installed at the beam nest position or hung, before pouring, checking the position of the steel beam through coordinate lofting, and correcting the levelness of the steel beam by using a horizontal ruler;
and 7, recalibrating the installation center line or side line of the overhead man car on the steel beam. After the steel beam is installed and before the fifth step, the central line is installed on the overhead man car calibrated on the top plate of the roadway, so that the blocking is serious, the central line is difficult to lead from the top plate due to the influence of wind, and the precision cannot be guaranteed. The center line or side line is calibrated on the steel beam, so that the steel rope tug equipment is convenient to mount quickly, and the quick debugging in operation is also convenient;
the method is well applied to No. 1 auxiliary inclined shaft overhead man-vehicle installation engineering, ongoing 4-coal western auxiliary transportation main lane overhead man-vehicle installation engineering and 4-coal central auxiliary transportation main lane overhead man-vehicle installation engineering. The progress and the measurement accuracy of the overhead man-car installation project are effectively guaranteed.
