Chuck clamp for loading and unloading well logging exploring tube radiation source

Abstract

The invention discloses a chuck clamp for loading and unloading a well logging exploring tube radiation source. The chuck clamp comprises a base and a revolving shaft arranged on the base, wherein a rotary chuck gear is arranged at the upper end of the revolving shaft; a rotary stepping motor is meshed with the rotary chuck gear through a transmission conical gear to drive the rotary chuck gear and the revolving shaft to rotate; a tongs holder is arranged on the rotary chuck gear; two opposite tongs are arranged on the upper surface of the tongs holder through slide rails; the two tongs are connected with a clamping stepping motor respectively; a transverse rod bracket is arranged on the base; a pin shaft is arranged on the transverse rod bracket; a transverse rod and the pin shaft rotate synchronously; the transverse rod stepping motor is connected with the pin shaft to drive the pin shaft to rotate. By adopting the chuck clamp, clamping and loosening of the well logging exploring tube can be realized, and a series of actions such as opening of a cabin door, loading and unloading of the radiation source, closing of the cabin door and the like can be finished automatically during clamping, so that potential threat to human health due to current manual operation is avoided. The chuck clamp is simple in mechanism and low in maintenance cost, and works stably and reliably.

Description

technical field [0001] The invention relates to the loading and unloading technology of the radioactive source of the well logging probe, specifically a chuck fixture for loading and unloading the radioactive source of the well logging probe. Well probe tube radioactive source loading and unloading technical field. [0002] Background technique [0003] In oil exploration, a well logging probe is needed, and a radioactive source is placed in the well logging probe, and then the logging probe with the radioactive source is sent downhole, and the radioactive source is used to detect whether there is oil in the area. There is an openable and closable door on the well logging probe, the lower part of the door is rotatably connected to the well logging probe through a rotating mechanism, and there is a cavity for placing radioactive sources on the door or inside the well logging probe. The source is placed in this cavity. [0004] At present, the loading and unloading of radio...
