AI Technical Summary

Problems solved by technology

[0002] The probe tube is a very important system component in the field of oil drilling. When the mandrel of the probe tube is put into the protective tube of the probe tube, the gap between the mandrel and the protective tube is very small due to the slender mandrel. The shock-absorbing rubber ring and the protective tube are interference fit, so it is very difficult to install the mandrel into the protective tube
[0003] When assembling the mandrel into the protective tube, because the mandrel is too long, if there is no tool to ensure the assembly, it is easy to collide or squeeze, and some mechanical parts or electronic parts will be damaged.
Moreover, during the assembly process, when it is assembled to the middle part, it is easy to get stuck

Abstract

The invention relates to a guiding assembly and disassembly structure of a central spindle and a protective barrel of a probe. The guiding assembly and disassembly structure comprises a central spindle supporting mechanism for placing the central spindle, a protective barrel clamping mechanism for fixing the protective barrel, and an axial movement mechanism, wherein the axial movement mechanism comprises a sleeve body and a guiding shaft, the sleeve body and the protective barrel are relatively dormant, and the guiding shaft moves axially in the sleeve body by virtue of a translation mechanism; the central spindle supporting mechanism, the protective barrel clamping mechanism and the sleeve body are arranged in sequence, and the axes of the spindle shaft, the protective barrel and the guiding shaft are in a same line; and the guiding shaft is detachably connected to the central spindle. The invention also relates to mounting and dismounting methods of the central spindle and the protective barrel of the probe. The guiding assembly and disassembly structure has the advantages that the structure is simple, the operation is convenient, the assembly is smooth, and parts have less possibility of being damaged, thus being applicable to the field of oilfield instruments.

Description

technical field [0001] The present invention relates to an oil field instrument, in particular to a guide assembly and disassembly structure for a mandrel of a probe tube and a protection cylinder, and an installation method and a disassembly method for realizing the assembly and disassembly of the mandrel and protection cylinder by using the guide assembly and disassembly structure . Background technique [0002] The probe tube is a very important system component in the field of oil drilling. When the mandrel of the probe tube is put into the protective tube of the probe tube, the gap between the mandrel and the protective tube is very small due to the slender mandrel. The shock-absorbing rubber ring and the protective tube are interference fit, so it is very difficult to install the mandrel into the protective tube. [0003] When assembling the mandrel into the protection tube, because the mandrel is too long, if there is no tool to ensure the assembly, it is easy to col...
