Abstract
The invention discloses a petroleum sleeve thread protector disassembly and assembly tool and the application thereof. The disassembly and assembly tool is composed of a handle, three clamps, a connecting chip and a pin; three clamps are not hermetically connected by the head and the tail of the pin; the top end of the first clamp is connected with the connecting chip by the pin; the tail end of the final clamp is connected with the tail end of the handle by the pin; the lower part of the handle is provided with an adjusting guiding trough; the other end of the connecting chip is movably arranged in the adjusting guiding trough by the pin. The application of the invention is that the petroleum sleeve thread protector disassembly and assembly tool is opened and sleeved on the external surface of the thread protector; the pin in the guiding trough is adjusted to change the opening degree of the tool and the magnitude of the handle torque; the thread protector is clamped and the handle is rotated clockwise or anticlockwise so as to complete the disassembly and assembly operation of the thread protector. The petroleum sleeve thread protector disassembly and assembly tool has simple structure, convenient operation, easy manufacture, is extremely suitable for field operation, can effectively ensure the safe disassembly and assembly of the thread protector of the petroleum sleeve thread during the production, transportation and usage process, and effectively protect the thread of the petroleum sleeve.
Description
Technical field
The present invention relates to a kind of tool for installing and dismounting petroleum casing pipe screw protector and application thereof of oil country tubular good technical field of tools; be particularly related to a kind of in petroleum casing pipe processing, when using; can load and unload the petroleum casing pipe thread protector effectively, safely, protection petroleum casing pipe screw thread and injury-free tool for installing and dismounting petroleum casing pipe screw protector and the application thereof of thread protector.
Background technology
In screw thread processing, transportation and the use of oil country tubular good, the quality of screw thread directly influences the quality of finished product sleeve pipe, in drilling team's use, and the quality and the speed of well operations under the damage influence sleeve pipe of screw thread, even may cause down-hole accident.In order to prevent that screw thread from sustaining damage, screw thread protection device---thread protector must be installed on screw thread.
In whole process, in order to protect screw thread, the loading and unloading of thread protector are very frequent.And also not having the good especially thread protector handling instrument of a cover, thread protector loading and unloading repeatedly to cause production efficiency low now, cost of labor increases.And incorrect handling method can cause the damage of screw thread, thereby causes substandard products, waste product, increases the work for inspection amount, increases production cost.
Summary of the invention
The technical issues that need to address of the present invention just are to overcome the defective of not having in the prior art; a kind of tool for installing and dismounting petroleum casing pipe screw protector and application thereof are provided; it is a kind of instrument that is exclusively used in the loading and unloading of petroleum casing pipe thread protector; can guarantee the safety loading and unloading of petroleum casing pipe screw thread thread protector when production, transportation, use effectively, protect the petroleum casing pipe screw thread effectively.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of tool for installing and dismounting petroleum casing pipe screw protector of the present invention, described handling instrument is made of handle, three clamps, connection chip and pins, three clamps are by the not sealing connection of pin head and the tail, the top of first clamp by pin be connected chip and connect, the tail end of last clamp is connected by the tail end of pin and handle, the handle bottom is provided with an adjusting guide groove, the other end of described connection chip is movably arranged on by pin and regulates in the guide groove, forms the lasso of a sealing between such three clamps and connection chip and the handle tail end.
Described clamp is the strip steel plate of band circular arc, and the clamp inboard evenly is provided with sawtooth, and the circular arc two ends are provided with the connection circular hole.The thread protector instrument relative slip occurred with thread protector when sawtooth can prevent the casing screw protector loading and unloading effectively, thus rapid, safe loading and unloading thread protector.
Described handle two ends are provided with circular hole.
Described adjusting guide groove is that circular arc is regulated guide groove.
Described connection chip two ends are provided with the connection circular hole.
One end of described pin is provided with inflation port, assembles the back awl and hits inflation port, and the pin tail end is expanded, and can prevent that pin from withdrawing from.
The present invention discloses the application of described tool for installing and dismounting petroleum casing pipe screw protector, handling instrument of the present invention is opened, be placed on the thread protector outer surface, the chucking thread protector, because described connection chip is movably arranged on by pin and regulates in the guide groove, can change the size of open size of instrument and handle moment, according to the direction that requires the selection tool rotation of loading, unloading operation, clockwise or the counterclockwise rotation fixed handle, can finish the loading and unloading of thread protector.
The beneficial effect of technical scheme provided by the invention is: the present invention is simple in structure, and is easy to operate, makes easily, is fit to very much field work.Can guarantee the safety loading and unloading of petroleum casing pipe screw thread thread protector when production, transportation, use effectively, protect the petroleum casing pipe screw thread effectively.Thread protector instrument and the relative slip of thread protector appearance prevented to damage thread protector when the sawtooth by the clamp inner surface can prevent the casing screw protector loading and unloading effectively.
