Replaceable screw twisting tool capable of being matched with manipulator for assembling and disassembling logging exploration pipe radioactive source

Abstract

The invention discloses a replaceable screw twisting tool capable of being matched with a manipulator for assembling and disassembling a logging exploration pipe radioactive source. The replaceable screw twisting tool comprises a suction cup, a rotating shaft, a force transfer sleeve and a nut sleeve. The rotating shaft is arranged in a center through hole of a protruding section of the suction cup. One end of the rotating shaft is provided with a clamping groove, and the other end of the rotating shaft is provided with a spring containing cavity. A spring is arranged in the spring containing cavity. The driving end of the nut sleeve enters the force transfer sleeve from a minimum inner hole of the force transfer sleeve. The driving end of the nut sleeve is sleeved with an anti-disengaging ferrule in a close fit mode. The force transfer sleeve is arranged on the rotating shaft in a sleeving mode through a maximum inner hole and fixedly connected with the rotating shaft. The spring is compressed between the bottom of the spring containing cavity and the end face of the driving end of the nut sleeve. The screw twisting tool can be matched with the manipulator to complete tightening or loosening of screws on a bin gate of the logging exploration pipe radioactive source so that the bin gate can be closed or opened; the screw twisting tool is fast and easy to operate and high in accuracy; the screw twisting tool has a flexible connection function and can provide effective buffer space to protect equipment.

Description

technical field [0001] The invention relates to the loading and unloading technology of well logging probe radioactive sources, specifically a manipulator replaceable screw-tightening tool for loading and unloading well logging probe radioactive sources. The screw on the door is tightened and unscrewed to close or open the bin door for installing or removing the radioactive source, which belongs to the technical field of well logging probe radioactive source loading and unloading. Background technique [0002] In oil exploration, well logging probes are used. The well logging probes are filled with radioactive sources, and then the logging probes with radioactive sources are sent downhole, and the radioactive sources are 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 r...

AI Technical Summary

Problems solved by technology

Although manual loading and unloading is very simple, it is not suitable for long-term operation due to the harmfulness of radioactive sources to the human body. Therefore, it is currently being considered to use industrial robots (manipulators) to automatically complete the loading and unloading of radioactive sources, that is, open and close the storage of radioactive sources by manipulators the door of the warehouse, and then take out the radioactive source

To open and close the door, the first thing to do is to screw the screw. Although there are many tools for automatically screwing the screw by the machine, the tool for screwing the screw in this application needs to cooperate with the manipulator, and the existing tool for screwing the screw In the process of combining with the manipulator, the complexity of the structure will be greatly increased
