Clinometer calibration stand

Abstract

The invention relates to a clinometer calibration stand. Adjustable landing legs are arranged at the bottom of a three-leg support frame, an upright column is arranged on the three-leg support frame, a mandrel is coaxially arranged in the axial center of the upright column, a rotary table is arranged above the mandrel, and a Y-axis vernier angle caliper is arranged at the periphery of the rotary table; a square supporting seat is connected to and positioned above the rotary table, a transmission shaft penetrates through the square supporting seat to be connected with a rotating disc large gear, a gear supporting seat of an adjusting small gear is arranged above the square supporting seat, the adjusting small gear is meshed with the rotating disc large gear, and an X-axis vernier angle caliper is arranged on the gear supporting seat; a U-shaped connecting frame is arranged at the other side of the transmission shaft, and a Z-axis vernier angle caliper is erected on the U-shaped connecting frame. The clinometer calibration stand disclosed by the invention can be used for accurately calibrating the angles of three coordinate axes by being provided with a three-circumference adjustable rotating mechanism and carries out micro-adjustment through the vernier scale of each coordinate axis, thereby enhancing the measurement accuracy, guaranteeing the convenience for adjustment and ensuring the measurement accuracy of a clinometer.

Description

technical field [0001] The invention relates to an inclinometer calibration platform, which is suitable for the assembly, adjustment and calibration of the inclinometer used in oil field drilling. Background technique [0002] At present, the exact position of the oil layer has been proven during the drilling of oil wells. When mining, sometimes it is necessary to avoid complex geological layers and buildings above. It is necessary to use an inclinometer to measure the angle of the drill bit when drilling to ensure the exact position of the well. When the inclinometer is processed, manufactured and assembled, the measurement accuracy also needs to be adjusted, and the accuracy of the inclinometer also needs to be adjusted after a period of use. There is no suitable and accurate calibration table to complete this work. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a calibration table for an inclinometer. The cal...

[0002] At present, the exact position of the oil layer has been proven during the drilling of oil wells. When mining, sometimes it is necessary to avoid complex geological layers and buildings above. It is necessary to use an inclinometer to measure the angle of the drill bit when drilling to ensure the exact position of the well. When the inclinometer is processed, manufactured and assembled, the measurement accuracy also needs to be adjusted, and the accuracy of the inclinometer also needs to be adjusted after it has been used for a period of time. There is no suitable and accurate calibration table to complete this work.
