The embodiment of the application provides a tool for dismounting an upper joint and a lower joint of a logging instrument, as shown in fig. 1 to 5, the tool for dismounting an upper joint and a lower joint of a logging instrument is used for mounting the upper joint and the lower joint on an electronic framework 3 and dismounting the upper joint and the lower joint from the electronic framework 3, the tool for dismounting comprises an upper joint sleeve 11, a lower joint sleeve 21, a drawing tool 4 and a conversion head 22, the upper joint sleeve 11 is mounted at one end, close to the upper joint 1, of the electronic framework 3, the drawing tool 4 is mounted at one end, far away from the upper joint 1, of the upper joint sleeve 11, and the drawing tool 4 can extend into the upper joint sleeve 11 and be matched with the upper joint 1 for dismounting the upper joint; lower clutch bush 21 installs the one end that is close to lower clutch 2 on electronic skeleton 3, and the one end of keeping away from lower clutch 2 at lower clutch bush 21 is installed to drawing instrument 4, and drawing instrument 4 can stretch into in lower clutch bush 21 and cooperate with lower clutch 2 through crossover sub 22 for dismouting lower clutch 2.
The switching head 22 is in threaded connection with the free end 23 of the lower joint, and the switching head 22 is matched with the drawing tool 4 so as to facilitate the disassembly (installation) of the lower joint 2; the free end 12 of the upper coupling, which is structurally different from the lower coupling 2, can be directly engaged with the pulling tool 4. The drawing tools 4 can be provided in two, which are respectively mounted on the upper adapter sleeve 11 and the lower adapter sleeve 21; the drawing tool 4 can be only arranged, the drawing tool is firstly arranged on the upper joint sleeve 11 to carry out the dismounting work of the upper joint 1, and then arranged on the lower joint sleeve 21 to carry out the dismounting work of the lower joint 2, and when only one set of drawing tool 4 is used, the complexity of the dismounting tool can be greatly reduced. It should be noted that the diameter of the sleeve should be slightly larger than the diameter of the joint (or the outer diameter of the seal ring on the joint) to avoid damaging the seal ring during disassembly and assembly.
In an exemplary embodiment, as shown in fig. 1 and 2, the drawing tool 4 includes a T-bar 41 and a drawing pin 42, the drawing pin 42 is disposed at a distal end of the T-bar 41, and the T-bar 41 carries the drawing pin 42 to move axially and rotate. The T-shaped rod 41 is connected with a lead screw, and the lead screw drives the drawing pin 42 to axially move through the T-shaped rod 41. Namely: the lead screw controls the linear movement of the T-bar 41, and the handle of the T-bar 41 adjusts the rotation of the T-bar 41 (pull pin 42). It should be noted that the T-bar may be a unitary structure, such as: welding into a whole or directly forming into a whole; the structure can also be a split structure, for example: the T-shaped rod consists of a straight rod and a handle fixed at the end part of the straight rod through threads.
The handle of the T-bar 41 is arranged at the front end of the T-bar 41, the pulling pin 42 is arranged at the tail end of the T-bar 41, and the pulling pin 42 is used for matching with the conversion head 22 and the free end 12 of the upper joint. The T-bar 41 and the pull pin 42 may be of a unitary construction such that the T-bar 41 moves the pull pin 42 back and forth (axially) and rotates. Specifically, as shown in fig. 5, two L-shaped grooves 221 are symmetrically disposed on the conversion head 22, and the pulling pin 42 is inserted into the L-shaped grooves 221, so that the T-shaped rod 41 drives the lower connector 2 to move back and forth (axially) through the pulling pin 42 and the conversion head 22. The free end 12 of the upper joint is also provided with a groove for matching and fixing with the pulling pin 42, and the pulling pin 42 is clamped in the groove, so that the T-shaped rod 41 drives the upper joint 1 to move forwards and backwards (axially) through the pulling pin 42. The drawing pin 42 is driven by the lead screw to move back and forth, so that the drawing machine is convenient and labor-saving. Of course, a screw structure may not be adopted, and the T-shaped rod 41 may be directly pushed in and pulled out by manpower, which may be set according to practical situations, and the present application is not limited thereto.
