Abstract
The utility model provides a pick of reliable anticreep belongs to coal winning machinery and development machinery auxiliary component technical field, and its structure includes pick body and pick base, seted up the through -hole on the pick base, in the through -hole of pick base is stretched into downwards to the lower part of pick body, the lower part terminal surface of pick body is connected with anticreep spare, just anticreep spare stretches out the through -hole of pick base downwards, anticreep spare stretches out the part of pick base through -hole and has still seted up the pinhole, the the central axis of pinhole is coincidence and nonparallel in the the central axis of pick body, and the fixed pin cooperation is inserted in the pinhole of anticreep spare with the purpose that prevents that the pick body from deviating from from the through -hole of pick base in, simultaneously, does not still influence the normal use of pick, and is reliable and stable.
Description
Technical field
The utility model relates to mining machinery accessory technical field, specifically a kind of pick of reliable anticreep.
Background technology
In coal mining, in mining machinery operating mechanism, the performance of the broken coal petrography of pick directly affects the specific energy consumption of mining machinery, reliability and working life thereof.At present, in coal mining machine and development machine work, ubiquity pick loses a difficult problem that is serious, that roll up cost.
Summary of the invention
Technical assignment of the present utility model solves the deficiencies in the prior art, provides a kind of pick of reliable anticreep.
The utility model solves the technical scheme that its technical problem adopts:
A kind of pick of reliable anticreep, comprise pick body and pick base, described pick base offers through hole, the bottom of pick body is stretched in the through hole of pick base downwards, the lower end surface of described pick body is connected with anti-falling piece, and described anti-falling piece stretches out the through hole of pick base downwards; The part that described anti-falling piece stretches out pick base plate through holes also offers pin-and-hole, and the central axis of described pin-and-hole does not overlap and is not parallel to the central axis of pick body, and steady pin coordinates the pin-and-hole inserting anti-falling piece interior to prevent pick body from deviating from from pick base.
Preferably, described anti-falling piece is round steel, and round steel is welded to connect the bottom end face in pick body, and the diameter of round steel is not more than the diameter that pick body stretches into pick base plate through holes part.
Further, the diameter of described round steel equals the lower diameter of pick body, and the central axes of round steel is in the central axis of pick body.
Preferably, described anti-falling piece is round steel, and the outer surface of upper of round steel has external screw thread, and the bottom end face of above-mentioned pick body offers screwed hole, and the external screw thread on round steel top coordinates in the screwed hole of screw-in pick body bottom portion end face.
Preferably, the central axis upright of described pin-and-hole is in the central axis of pick body.
The beneficial effect that the pick of a kind of reliable anticreep of the present utility model is compared with prior art produced is:
The utility model structure is simple, reasonable in design, by arranging anti-falling piece at the bottom end face of pick body, and anti-falling piece offers pin-and-hole, when steady pin coordinates the pin-and-hole inserting anti-falling piece, realize the object preventing pick body from deviating from pick base plate through holes, simultaneously, also do not affect the normal use of pick, reliable and stable.
