Abstract
The utility model belongs to the technical field of the centralizer is dismantled, concretely relates to interchangeable centralizer well head extracting tool. Comprises a clamping cylinder, a positioning rib and an auxiliary fixing rib; the positioning ribs are five and are uniformly fixed on the periphery of the outer part of the clamping cylinder, the front end of each positioning rib is located in the middle of the clamping cylinder, and the auxiliary fixing ribs are fixed on the outer part of the positioning ribs to fix the five positioning ribs together. The tool is simple in design, convenient to machine and high in practical value, solves the problem that the replaceable screw drilling tool centralizer is difficult to replace, and saves both time and cost.
Description
Technical Field
The utility model belongs to the technical field of the centralizer is dismantled, concretely relates to interchangeable centralizer well head extracting tool.
Background
At present, the screw drill with the replaceable centralizer is used in the drilling engineering of petroleum and natural gas, and the screw drill can replace centralizer rib sleeves with different sizes and styles according to the drilling engineering requirement, so that the drilling requirement is met.
The replacement method of the centralizer of the common screw drill comprises two replacement modes, wherein the first mode is to reassemble a new screw drill; the second is to carry out the change of whole centralizer, and this kind of mode needs to carry out holistic dismantlement, change, equipment to the screw rod drilling tool, is not different from the screw rod drilling tool and has carried out the reorganization process again. This not only wastes time, but also increases the production cost.
The replaceable centralizer screw drill tool has no special tool when replacing the centralizer, so that the disassembly is very inconvenient, and particularly for large-size centralizers, because the size value of the centralizer screw drill tool exceeds the caliber of a disassembly frame clamping device, a centralizer rib sleeve cannot pass through a clamping hole, so that the disassembly is more difficult.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a interchangeable centralizer well head extracting tool to solve the problem that exists among the background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a removable centralizer well head extracting tool which characterized in that: comprises a clamping cylinder, a positioning rib and an auxiliary fixing rib; the positioning ribs are five and are uniformly fixed on the periphery of the outer part of the clamping cylinder, the front end of each positioning rib is located in the middle of the clamping cylinder, and the auxiliary fixing ribs are fixed on the outer part of the positioning ribs to fix the five positioning ribs together.
Preferably, the number of the auxiliary fixing ribs is three.
Compared with the prior art, the utility model, its beneficial effect is:
the tool is simple in design, convenient to machine and high in practical value, solves the problem that the replaceable screw drilling tool centralizer is difficult to replace, and saves both time and cost.

fig. 2 is a side view of the present invention;
fig. 3 is a schematic view of the application of the present invention.
Detailed Description
The following detailed description of the preferred embodiments of the present invention is provided in connection with the accompanying drawings.
As shown in fig. 1 and 2, the wellhead disassembling tool with the replaceable centralizer comprises a clamping cylinder 1, a positioning rib 2 and an auxiliary fixing rib 3; the positioning ribs are five and are uniformly fixed on the periphery of the outer part of the clamping cylinder, the front end of each positioning rib is located in the middle of the clamping cylinder, and the auxiliary fixing ribs are fixed on the outer part of the positioning ribs to fix the five positioning ribs together.
As shown in figure 3, the device is integrally installed on a disassembly and assembly frame in the prior art, a clamping cylinder in the device is clamped in a rotary clamping hole of the disassembly and assembly frame, rib plates 4 of an interchangeable centralizer to be disassembled are sleeved in positioning ribs, and the space of five rib plates is mutually embedded with five ribs of the positioning ribs. The movable part of the assembling and disassembling stand clamps the body of the replaceable centralizer, and the rotating part of the assembling and disassembling stand rotates to drive the rotation of the disassembling tool of the replaceable centralizer. Because the positioning rib is matched with the rib flap of the replaceable centralizer rib sleeve, the replaceable centralizer rib sleeve rotates when the replaceable centralizer dismounting tool rotates, and therefore the purpose of assembling and disassembling the replaceable centralizer is achieved.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
