Description
Technical Field
The utility model belongs to the technical field of the disconnected round pin extractor frock, especially, relate to a disconnected round pin takes out instrument.
Background
The split pin (or D-shaped clamp) of the fixed pin shaft in the coal mine machinery can not be taken out smoothly due to corrosion, the split pin is cut off at the leaking part in the traditional taking-out method, a punch is knocked by a hand hammer to punch the split pin part in the hole, the punch is easy to damage and smash hands, the taking-out speed is low, time and labor are wasted, and the labor intensity of workers is high.
Disclosure of Invention
The utility model aims at providing a broken pin takes out instrument has safe in utilization, takes out fastly, reduces workman intensity of labour's advantage.
In order to achieve the above purpose, the utility model adopts the technical scheme that:
a broken pin taking-out tool comprises a gas shovel, a threaded drill rod positioned at the head of the gas shovel, a flat-head steel nail positioned at the head of the threaded drill rod, and a threaded sleeve fixedly connecting the flat-head steel nail and the threaded drill rod.
Furthermore, the outer side of the bottom of the threaded drill rod is provided with threads, the bottom of the threaded drill rod is provided with a boss protruding outwards, and the area of the boss is larger than that of the head of the flat head steel nail.
Furthermore, the thread bush is hollow cylinder, the upper end of the inner part of the thread bush is provided with a thread drill rod and a flat head steel nail head accommodating cavity, the lower part of the thread bush is provided with a flat head steel nail body accommodating cavity, and the diameter of the nail body accommodating cavity is smaller than that of the flat head steel nail head.
Further, the outer diameter of the tack body of the tack steel nail is smaller than the outer diameter of the broken pin to be taken out.
The utility model has the advantages that: a flat head steel nail is used for replacing a punch; the method has the advantages that the air shovel drill rod with the threaded head is manufactured, the flat-head steel nail is fixed at the head of the air shovel drill rod through the threaded sleeve, the broken pin is taken out through high-frequency striking of the air shovel, manufacturing cost is low, and labor intensity of workers can be reduced.
