The invention discloses a position detecting device for a drilling tool during convey. The position detecting device comprises a drilling rod stopping pin, a proximity switch, a stopping ring, a first semi-circular clamping plate, a second semi-circular clamping plate, clamping plate fixing screws, an upper supporting plate, a lower supporting plate, a rotating-resistant block and a proximity switch fixing screw. The drilling rod stopping pin is used for mounting the proximity switch and fixing the same through a screw so as to prevent the same from shifting and affecting detecting results; the drilling rod stopping pin is provided with through annular grooves, positions for the two semi-circular clamping plates to be mounted into the annular grooves can be changed, and accordingly the device can be in an operating state or a non-operating state; four round holes, which are right opposite vertically, at different positions are formed on the upper supporting plate and the lower supporting plate, mounting positions of the drilling rod stopping pin can be changed, and the device can be adaptable to drilling tools with different diameters. The device is mounted on a drilling tool conveying platform and beside a drilling rod frame and a plate overturning mechanism; when the drilling tool moves in the detecting range of the proximity switch, the proximity switch sends step signals to control the plate overturning mechanism to act so as to overturning the drilling tool into the platform, so that the plate overturning mechanism acts automatically, the drilling tool can be rolled into the platform from the drilling tool frame smoothly, and actions are consistent, accurate and fast.
Description
technical field [0001] The invention relates to a device for a deep well drilling rig, in particular to a position detection device for a drilling tool moving process that is matched with the platform of a drilling tool transporting device. Background technique [0002] The fully hydraulic drilling tool transport device is favored among the peripheral equipment of major drilling rigs for its stable and efficient performance. However, deep continental scientific drilling puts forward higher technical requirements for the transportation of drilling tools on the platform. The drill pipe support and the flap mechanism are needed to transport the drill pipe on the platform, but how to control the coordination of the two mechanisms is a key issue. an important subject. When the drill rod support is lifted by the hydraulic cylinder, the drilling tool rolls along the drill rod support to the inside of the platform, but at the same time, there will be a height difference between the...
