Abstract
The invention relates to a novel winding drum. The publicly-known winding drum in hoisting equipment is used as a thread groove for winding a sling wire rope, comprises spiral grooves with uniform pitch, needs a guide structure in the winding process and generates severe abrasion and extrusion phenomena or a rope disorder phenomenon sometime, thereby severely influencing the use effect and the service life of the hoisting equipment. The novel winding drum designs each circle of groove on the surface of a steel drum into a straight groove and an inclined groove distributed at intervals so as to overcome the defects. The invention has the advantages of order distribution, heavy carrying capability, good stability, long service life, and the like.
Description
Technical field
The present invention relates to a kind of novel winding drum, be applicable to the winding of steel rope in the elevator machinery.Belong to mechanical manufacturing field.
Background technology
Reel in the known weight-lifting equipment generally all is to produce the continuous thread connected in star at the metal cylinder outside face, the ground floor steel rope of being close to mandrel surface in order to arrange, and when lifting altitude is big, need multiple wraps, produce friction and extruding between the steel rope, thereby the damage steel rope can not normally twine and discharge also easy sometimes disorder cable, what have causes the reel rotation imbalance, causes very big harm to weight-lifting equipment.Thereby people wish to have a kind of novel winding drum that can overcome above-mentioned defective to come out.
Summary of the invention
Twine friction in the reel process, extruding and unbalanced problem in order to solve steel rope, the invention provides a kind of novel winding drum.
To achieve these goals, technical scheme of the present invention comprises that steel cylinder, straight trough, skewed slot constitute.The steel cylinder outer surface thread is designed to straight trough, skewed slot is spaced apart.All straight troughs are arranged on the identical central angle of steel cylinder central axis with skewed slot is corresponding respectively, and two sections corresponding central angle sums of straight trough are 25/18 π radian on the same spiral, and two sections corresponding central angle sums of skewed slot are 11/18 π radian.
The present invention has advantages such as arranging in order, be difficult for disorder cable, load carrying ability are big, good stability, long service life.
Description of drawings
Accompanying drawing 1 is front view of the present invention.
Accompanying drawing 2 is expansion drawing of the present invention.
In the accompanying drawing, 1 steel cylinder, 2 straight troughs, 3 skewed slots.
The specific embodiment
The present invention is applied among the transfer crane, during hoisting heavy, steel rope is close to along straight trough 2 and skewed slot 3 and is wound on the steel cylinder 1, and the shape of steel rope is consistent with the grooving on steel cylinder 1 surface, shape of threads between straight monoclinic phase, the part of the steel rope of the second layer is embedded between the steel rope of ground floor successively, form the shape of threads between the straight monoclinic phase identical with ground floor, discharge the 3rd layer successively according to same procedure ... in said process, because between the straight monoclinic phase of groove, limit the winding direction of rope, realized purpose of the present invention.
Claims (2)
1, a kind of novel winding drum, it is to be made of steel cylinder, straight trough, skewed slot, it is characterized in that the thread groove of steel cylinder outside face is designed to straight trough, skewed slot is spaced apart.
2, a kind of novel winding drum according to claim 1, it is characterized in that on the identical central angle of all straight troughs and the corresponding steel cylinder central axis of skewed slot difference, and two sections cooresponding central angle sums of straight trough are 25/18 π radian on the same spiral, and two sections cooresponding central angle sums of skewed slot are 11/18 π radian.
