Abstract
The invention discloses a thread protecting fastener used for an oil casing thread protector assembly and disassembly tool and the application thereof. The fastener is made from a long strip steel plate with arc, saw teeth are uniformly formed on the inner side of the fastener, and connecting round holes are opened on two ends of the arc. The fastener is applied in the oil casing thread protector assembly and disassembly tool. The assembly and disassembly tool is composed of a handle, three fasteners, a connecting chip and a pin, wherein the three fasteners are in a head-to-tail unsealed connection; the head end of a first fastener is connected with the connecting chip through the pin, the tail end of a third fastener is connected with the tail end of the handle. An adjusting guide groove is formed in the lower part of the handle; the other end of the connecting chip is movably mounted in the adjusting guide groove through the pin, thus, a sealed collar is formed among the three fasteners, the connecting chip and the tail end of the handle. The fastener can effectively prevent the relative slip between the thread protector tool and the thread protector in the assembly and the disassembly of the casing thread protector through the saw teeth on the inner surface of the fastener, thereby preventing the thread protector from being damaged.
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 thread protector clip for petroleum casing pipe thread protector handing tool 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 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 thread protector clip for petroleum casing pipe thread protector handing tool and application thereof are provided, 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.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of thread protector clip for petroleum casing pipe thread protector handing tool of the present invention, 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.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.
Described sawtooth is 90 ° of sawtooth.
Described circular arc radian is 30 °-160 °.
The present invention is applied in the tool for installing and dismounting petroleum casing pipe screw protector, 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.
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 counterclockwise rotation fixed handle can be finished the loading and unloading of thread protector.
Thread protector instrument and the relative slip of thread protector appearance prevented to damage thread protector when the sawtooth of the present invention by the clamp inner surface can prevent the casing screw protector loading and unloading effectively.
Tool for installing and dismounting petroleum casing pipe screw protector of the present invention can guarantee the safety loading and unloading of petroleum casing pipe screw thread thread protector when production, transportation, use effectively, has protected the petroleum casing pipe screw thread effectively.
