The invention discloses a disassembling device and method for a small-diameter pump-out natural gamma-ray spectrum logging instrument, and belongs to the technical field of logging instrument tool design. The disassembling device comprises a handle, a pull rod, an unlocking rod, a spring seat, a base body, a pull head and a compression spring; the unlocking rod is installed on the base body in the direction parallel to the axis of the base body and penetrates through a slot of the base body; the pull head is installed on the inner circumferential surface of the end, provided with the slot, of the base body in a sleeved mode, and one-way axial limiting is conducted through matching of annular limiting tables on the inner circumferential surface of the base body and protrusions of the pull head; the spring seat is installed on the inner circumferential surface of the other end of the base body in a sleeved mode, the pull rod penetrates through the spring seat, one end of the pull rod is fixedly connected with the pull head, and the handle is fixed at the other end of the pull rod; the compression spring is installed on the pull rod, one end of the compression spring abuts against the step face of the inner circumferential surface of the base body, and the other end of the compression spring abuts against the end face of the spring seat. The disassembling device is simple in structure and convenient to operate, and it is guaranteed that the sealing surface of an outer shell of the instrument and the core surface are not damaged in the disassembling process.
Description
technical field [0001] The invention belongs to the technical field of tooling design for well logging instruments, and in particular relates to a dismantling device and method for a small-diameter pumping natural gamma ray spectrum logging instrument. Background technique [0002] During commissioning and maintenance of small-diameter pumped natural gamma ray spectrometer logging tools, it is often necessary to pull the tool core out of the tool casing. However, the existing disassembly device needs to use many devices to disassemble the instrument, the operation is very inconvenient, and it is easy to cause the wire to be scratched during the disassembly process, and it is also easy to cause damage to the probe in the core of the instrument due to strong impact and vibration during disassembly. crystals and photomultiplier tubes. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a dismantling device and method for a s...
