Abstract
The utility model relates to a protection device for a grab bucket steel wire rope. The protection device is fixed between a left side plate and a right side plate by two identical pulleys and a spacer sleeve between the two pulleys through the same one spindle, the protection device is characterized in that two cross rolls are arranged above the left side and the right side of the edge of the pulley, bearings are inserted in two ends of each cross roll, and are arranged on the left side plate and the right side plate through small shafts; retainer rings taking each cross roll as a center are welded and fixed at the edges, close to the pulley, of the two sides of the spacer sleeve. The protection device has the beneficial effects of being capable of preventing the steel wire rope from jumping out of a pulley groove, effectively reducing the wear of the steel wire rope, and playing a positive role on the running efficiency of a crane.
Description
Technical field
The utility model relates to protecting device for wire rope, especially steelworks slag in a kind of crane grab bucket of steel-making enterprise across the protecting device for wire rope in crane grab bucket.
Background technology
The 3 cubic meter grab buckets that steelworks slag uses across crane, its steel rope consumption is always larger, grab bucket is affected by it also service life, analyzing major cause is due to work under bad environment of living in, during because of work, produces vibration, wire rope load shakiness, makes 28 millimeters of steel ropes of Φ that primary and secondary volume uses often go out groove at fixed pulley place, after going out groove, produce serious friction with spacing sleeve, cause steel rope breakage, the partial portion that makes to grab bucket is hit impaired, thereby has reduced steel rope and grabbed bucket service life.This greatly affects the operating efficiency of crane, has increased spare parts consumption simultaneously.Protection steel rope, can improve crane operating efficiency and play positive role the service life of raising steel rope.
Summary of the invention
The purpose of this utility model is: design a kind of slag across the protecting device for wire rope in crane grab bucket, prevent that steel rope from going out groove at fixed pulley place, i.e. a kind of fender guard of steel wire rope of grab bucket.
The technical solution of the utility model is achieved in that
Improve design predetermination assembly pulley and be fixed between left and right side plate and formed by same main shaft by the spacing sleeve between two identical pulleys and two pulleys, pulley and main shaft can rotate relatively freely, and spacing sleeve, main shaft and side plate are fixed.When work, steel rope often goes out groove and spacing sleeve friction, causes steel rope breakage.
Present design is: a barrel roll is respectively housed above pulley edge left and right side, and barrel roll is parallel with main shaft, and every barrel roll two ends stud with bearing and are arranged on left and right side plate by little axle, and barrel roll and side plate can rotate relatively freely; Respectively be welded with the baffle ring centered by every barrel roll in spacing sleeve both sides near pulley edge place.The effect of four baffle rings is to prevent that the vibrated external force of steel rope from extruding gap between pulley and barrel roll.The object of barrel roll is installed is and prevent that steel rope from jumping out pulley groove, every barrel roll surface does not contact at ordinary times with the steel rope in pulley, and in the time that barrel roll is encountered in steel rope vibration, the stressed rotation of barrel roll energy prevents and steel rope friction, and can prevent that steel rope from jumping out pulley groove.
The beneficial effects of the utility model are: can prevent that steel rope from jumping out pulley groove, effectively reduce steel rope abrasion, play positive role to improving crane operating efficiency.

Detailed description of the invention
Improving design predetermination assembly pulley is fixed between left and right side plate (1) and is formed (seeing Fig. 1) by same main shaft (2) by the spacing sleeve (4) between two identical pulleys (3) and two pulleys (3), pulley (3) can rotate relatively freely with main shaft (2), and spacing sleeve (4), main shaft (2) are fixed with side plate (1).Present design is: in pulley (3) edge left and right side top, a barrel roll (5) is respectively housed, barrel roll (5) is parallel with main shaft (2), every barrel roll (5) two ends stud with bearing and are arranged on left and right side plate (1) by little axle (6) upper, and barrel roll (5) can rotate relatively freely with side plate (1); Respectively be welded with the baffle ring (7) (seeing accompanying drawing 2) centered by every barrel roll (5) in spacing sleeve (4) both sides near pulley (3) edge.The effect of four baffle rings (7) is to prevent that the vibrated external force of steel rope (8) from extruding gap between pulley (3) and barrel roll (5).The object that barrel roll (5) is installed is to prevent that steel rope (8) from jumping out pulley groove, in the time that barrel roll (5) is encountered in steel rope (8) vibration, barrel roll (5) can stressed rotation prevents and steel rope (8) friction, and can prevent that steel rope (8) from jumping out pulley groove.
Claims (1)
1. the fender guard of a steel wire rope of grab bucket, by two identical pulleys (3), and spacing sleeve (4) between two pulleys (3) is fixed on a left side by same main shaft (2), composition between right side board (1), pulley (3) can rotate relatively freely with main shaft (2), spacing sleeve (4), main shaft (2) is fixing with side plate (1), it is characterized in that: on pulley (3) left side, edge, a barrel roll (5) is respectively equipped with in top, right side, barrel roll (5) is parallel with main shaft (2), every barrel roll (5) two ends stud with bearing and are arranged on a left side by little axle (6), on right side board (1), barrel roll (5) can rotate relatively freely with side plate (1), respectively be welded with the baffle ring (7) centered by every barrel roll (5) in spacing sleeve (4) both sides near pulley (3) edge.
