Abstract
The utility model relates to a steel wire rope antibouncer, in particular to a steel wire rope antibouncer on a larry pulley block of ship unloader pair. The steel wire rope antibouncer includes a pulley, a steel wire rope, an anti-bouncing bar supporter and an anti-bouncing bar. The pulley is arranged in the anti-bouncing bar supporter and the steel wire rope is arranged in a pulley slot. The anti-bouncing bar is fixedly arranged on the anti-bouncing bar supporter in the lateral orientation. The utility model is characterized in that the middle part of the anti-bouncing bar is provided with an arced bar bending outwards. The arced bar is provided with an internal circular arc and the internal circular arc is corresponding to the pulley slot. Both of the two end points of the internal circular arc point at the center of the puller slot along the tangent direction of the internal circular arc. The two sides of the arced bar are respectively provided with a baffle. The baffles are arranged between the anti-bouncing bar supporter and the edge of the pulley. A clearance is reserved between the baffle close to the edge of the pulley and the edge of the pulley. The utility model can effectively prevent the phenomenon of the steel wire rope bouncing from happening, thereby ensuring the stable operation of the ship unloader and improving the working efficiency of the ship unloader.
Description
Technical field
The utility model relates to a kind of steel rope anti-bouncing device, the steel rope anti-bouncing device on the secondary dolly assembly pulley of particularly a kind of ship unloaders.
Background technology
The grab bucket of bridge-type grab ship unloader is towed four ropes of dolly two lobes, by the lifting and the switching of four steel rope control grab buckets, and the assembly pulley operation of the major-minor dolly on the steel wire penetrating ship unloaders crossbeam.Two middle steel ropes are controlled the switching of grab bucket for opening and closing steel rope, and two steel ropes in the outside are hoisting cable, the rising and the decline of control grab bucket.Because grab bucket running velocity in operation is very fast, again because the quality of steel rope own is very big, inertia is very big, therefore the steel rope at secondary dolly assembly pulley place has very big relaxing after grab bucket contact charge level, if this moment, the fast control grab bucket was closed, open and close steel rope flaccid part branch and jump out, thereby cause that steel rope jumps out fault from the assembly pulley on the secondary dolly.It is cumbersome that the processing steel rope is jumped out the assembly pulley fault, needs the long period.
Jump out fault for avoiding steel rope, the now general technology that adopts mainly is at the upper and lower of assembly pulley the anti-pogo stick of one group of straight rod formula to be installed respectively, anti-pogo stick is very near from the pulley distance, and is lax and when will jump out when steel rope, directly is subjected to the compacting of anti-pogo stick and the pulley groove that rebounds.But because the distance of anti-pogo stick and pulley groove is too small, steel rope snaps into when preventing pogo stick stressed excessive; Because steel rope has flexibility, stressed can the distortion prevents that the space of pogo stick and pulley edge is bigger again again, so steel rope skids off from the space of anti-pogo stick and pulley edge easily.This anti-bouncing device can not play the effect that the protection steel rope is not job-hoped well.
The utility model content
The purpose of this utility model is to provide a kind of steel rope anti-bouncing device, and this steel rope anti-bouncing device can fall into pulley groove by guiding steel wire rope, and has reduced the space of pulley edge, thereby prevents that steel rope from jumping out assembly pulley.
The utility model is achieved in that a kind of steel rope anti-bouncing device, comprise pulley, steel rope, anti-jump shaft bar, anti-pogo stick, pulley is positioned at anti-jump shaft bar, steel rope is positioned at pulley groove, anti-pogo stick crosswise fixed is arranged on the anti-jump shaft bar, it is characterized in that: described anti-pogo stick is that interposition is equipped with a bandy bow, and this bow has circular arc in, and interior circular arc is corresponding to pulley groove.
Circular arc is that two end points of interior circular arc all point to the pulley groove center along the tangential direction of interior circular arc greater than the circular arc of 180 degree in described.
Described bow both sides respectively are set with a baffle plate, and baffle plate is between anti-jump shaft bar and pulley edge, and baffle plate also and between the pulley edge remains with a gap near pulley edge.As a kind of preferred structure, described baffle plate is a month dentition formula, and its lower edge is a circular arc, and lower edge is lower than the top of pulley.
The utility model is by being provided with a bow, strengthened on the steel rope between gap, and is stressed to lay down a part, makes steel rope again after last spring, can significantly reduce the stressed of steel rope along interior circular arc slip, thus the distortion of minimizing steel rope; Again since in the bow tangential direction of circular arc two-end-point all point to the pulley groove center, thereby the steel rope that guiding bounces out falls back in the pulley groove, has played good guiding function, has prevented jumping out of steel rope well.At the baffle plate that the both sides of bow increase, dwindled the gap of jumping out of steel rope, further protected steel rope from assembly pulley, not jump out.
The utility model can effectively prevent the generation of steel rope job-hopping phenomenon, has guaranteed the smooth operation of ship unloaders, has improved the operating efficiency of ship unloaders.
Description of drawings
Fig. 1 is the utility model steel rope anti-bouncing device structural representation.
Fig. 2 is the utility model steel rope anti-bouncing device right elevation.
Among the figure, 1 pulley, 2 steel ropes, 3 anti-jump shaft bars, 4 anti-pogo sticks, 5 pulley grooves, 6 bows, 7 interior circular arcs, 8 end points, 9 baffle plates.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, Fig. 2, a kind of steel rope anti-bouncing device comprises pulley 1, steel rope 2, anti-jump shaft bar 3, anti-pogo stick 4.Pulley 1 is positioned at anti-jump shaft bar 3, and pulley groove 5 is arranged on the pulley 1, and steel rope 2 is positioned at pulley groove 5, anti-pogo stick 4 crosswise fixed are arranged on the anti-jump shaft bar 3, anti-pogo stick 4 interpositions are equipped with a bandy bow 6, and this bow 6 has interior circular arc 7, and interior circular arc 7 is corresponding to pulley groove 5.The interior circular arc that present embodiment is selected for use is the circular arc greater than 180 degree, and two end points 8 of interior circular arc 7 all point to pulley groove 5 centers along the tangential direction of interior circular arc 7.
Referring to Fig. 2, bow 6 both sides respectively are provided with a baffle plate 9, baffle plate 9 between anti-jump shaft bar 3 and pulley 1 edge, baffle plate 9 near pulley 1 edge and and pulley 1 edge between remain with a gap.Baffle plate 9 is a month dentition formula, and its lower edge is a circular arc, and lower edge is lower than the top of pulley 1.
The utility model steel rope anti-bouncing device is such work: in the ship unloaders operation process, and behind grab bucket contact charge level, the relaxation that the steel rope 2 meeting generations at pulley 1 place are gone up largely.At this moment, the steel rope 2 in the pulley groove 5 bounces under action of inertia.Because anti-pogo stick 4 stage casings are a bow 6, steel rope 2 is laid down a part of power in the jump process that upsprings, steel rope 2 can slide along the interior circular arc 7 of bow 6 after spring is got up, further reduced the stressed of steel rope 2, thereby reduce the distortion of steel rope 2, steel rope 2 can fall into pulley groove 5 along interior circular arc 7 again simultaneously.Crescent baffle plate 9 near pulley 1 edge and and pulley 1 edge between remain with a gap, baffle plate 9 lower edges are a circular arc, its lower edge is lower than the top of pulley 1, has further limited the space of jumping out of steel rope 2, thereby has prevented steel rope 2 job-hopping phenomenons well.
