Abstract
The invention belongs to the technical field of geared drill stabilizers, in particular to relating to a geared drill stabilizer repairing method. The method is characterized by adding a wear-resisting sleeve on a wear position so as to prevent the stabilizer from broken due to serious local wear. The method comprises the following specific steps of: manufacturing the wear-resisting sleeve of which the original outside diameter is in accord with the original outside diameter of the wear position of the stabilizer and the length is 2-5 millimeters; integrally heat treating the machined wear-resisting sleeve; connecting the heat-treated wear-resisting sleeve on the wear position; and inserting a drill rod into the stabilizer and simultaneously fixing the wear-resisting sleeve by using the drill rod. The invention aims at repairing the failure form of serious local wear of the stabilizer outer wall, an outside diameter of an old stabilizer is increased to the original size by the mean of adding the wear-resisting sleeve and the wear resistance is increased, thus the stabilizer is prevented from being broken due to serious local wear and simultaneously the drill rod and drill bit are protected.
Description
Technical field
The invention belongs to gear wheel and bore the virtual calibrator for instrument transformer technical field, particularly relate to the method for repairing and mending that a kind of gear wheel bores virtual calibrator for instrument transformer.
Background technology
Virtual calibrator for instrument transformer has been connected stable drilling rod, drill bit effect with drilling rod and drill bit, prevent drilling rod heavy wear.It is the vitals of protection drilling rod and drill bit.The virtual calibrator for instrument transformer of rotary drill often needs to change general application life about 5000-7500 rice, and cost of winning is higher.The failure mode of finding virtual calibrator for instrument transformer by on-site inspection has: outer wall integral body or concentrated wear are serious; Alloy granule comes off.In order to prolong the application life of virtual calibrator for instrument transformer, adopt the mode of built-up welding to repair, but have following shortcoming:
1, working strength of workers is big in the repair process;
2, the welding position produces stress, and virtual calibrator for instrument transformer easily ruptures in the process of using;
3, easily come off after the packing material wearing and tearing, jeopardize belt and crushing system;
During 4, with the supporting use of new drilling rod, its appearance and size can not reach instructions for use, directly causes drilling rod heavy wear.These factors have all seriously influenced the application life of virtual calibrator for instrument transformer.
Summary of the invention
The purpose of this invention is to provide the method for repairing and mending that a kind of gear wheel bores virtual calibrator for instrument transformer, solve virtual calibrator for instrument transformer cost height, the life-span is low and repaiied old mode in the past problems such as the drilling rod damage are serious.
The objective of the invention is to realize by following technical proposals:
A kind of gear wheel of the present invention bores the method for repairing and mending of virtual calibrator for instrument transformer, it is characterized in that installing wear-resistant sleeve additional in the abrading section, avoids virtual calibrator for instrument transformer to take place because of the situation that concentrated wear seriously fractures to reach, and concrete steps are as follows:
1) make the wear-resistant sleeve of, a length long 2-5mm consistent with virtual calibrator for instrument transformer abrading section original outside diameter,
2) with the wear-resistant sleeve bulk heat treatmet that processes,
3) wear-resistant sleeve after the heat treatment is socketed in the abrading section of virtual calibrator for instrument transformer,
When 4) inserting drilling rod in the virtual calibrator for instrument transformer, utilize drilling rod that wear-resistant sleeve is fixed.
The present invention is directed to serious this failure mode of virtual calibrator for instrument transformer outer wall concentrated wear and repair, belong to a kind of mining rotary drill virtual calibrator for instrument transformer by repairing the design that old mode prolongs its life-span.Mainly to solve virtual calibrator for instrument transformer cost height, life-span low and repaiied old mode to problems such as the drilling rod damage are serious in the past.By installing wear-resistant sleeve additional old virtual calibrator for instrument transformer external diameter is increased to original size and increases wear resistence, avoid virtual calibrator for instrument transformer because of the situation that concentrated wear seriously fractures takes place, play the purpose of protection drilling rod and drill bit simultaneously thereby reach.The virtual calibrator for instrument transformer of this kind form of structure, solve virtual calibrator for instrument transformer in the past and repaiied the deficiency that old back exists in using, prolonged the life-span of repairing old virtual calibrator for instrument transformer and drilling rod greatly, the experimental data proof all can meet or exceed the application life of new virtual calibrator for instrument transformer application life by the virtual calibrator for instrument transformer of the method reparation.
The present invention has the following advantages:
1, installation and processing is easy, has reduced working strength of workers;
2, rehabilitation cost is low, and technology is simple;
3, avoided concentrating, thereby the accident of damaging virtual calibrator for instrument transformer takes place because of built-up welding causes stress.
4, this kind method is suitable for the reparation of different size virtual calibrator for instrument transformer, has prolonged the application life of virtual calibrator for instrument transformer.
Description of drawings
Fig. 1 is an experimental data statistical indicator comparison diagram of the present invention.
The specific embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of gear wheel of the present invention bores the method for repairing and mending of virtual calibrator for instrument transformer, it is characterized in that installing wear-resistant sleeve additional in the abrading section, avoids virtual calibrator for instrument transformer to take place because of the situation that concentrated wear seriously fractures to reach, and concrete steps are as follows:
1) make the wear-resistant sleeve of, a length long 2-5mm consistent with virtual calibrator for instrument transformer abrading section original outside diameter,
2) with the wear-resistant sleeve bulk heat treatmet that processes,
3) wear-resistant sleeve after the heat treatment is socketed in the abrading section of virtual calibrator for instrument transformer,
When 4) inserting drilling rod in the virtual calibrator for instrument transformer, utilize drilling rod that wear-resistant sleeve is fixed.
Ordinate is perforation rice road numerical value among the figure, and abscissa is the rig numbering, and the experimental data proof all can meet or exceed the application life of new virtual calibrator for instrument transformer application life by the virtual calibrator for instrument transformer of the method reparation.Wherein light column represents to represent in virtual calibrator for instrument transformer general application life, dark column to repair the application life of back virtual calibrator for instrument transformer.
The present invention increases to old virtual calibrator for instrument transformer external diameter original size and increases wear resistence by installing wear-resistant sleeve additional, avoids virtual calibrator for instrument transformer because of the situation that concentrated wear seriously fractures takes place thereby reach, and plays the purpose of protection drilling rod and drill bit simultaneously.The virtual calibrator for instrument transformer of this kind form of structure has solved virtual calibrator for instrument transformer in the past and has repaiied the deficiency that old back exists in using, and has prolonged the life-span of repairing old virtual calibrator for instrument transformer and drilling rod greatly, its year economic benefit be 300,000 yuan.
