Abstract
The utility model discloses a hoist hoisting mechanism in anticreep groove, it includes hoisting mechanism, lifting winding drum's side both ends are installed respectively and are pressed rope roller support, pressing rope roller support to pass through the bolt fastening and on the trolley frame, pressing the roller both ends of restricting and welded the minor axis, the both ends of minor axis penetrate the outer lane of passing through on it and fix with pressing rope roller support in deep groove ball bearing's the inner circle. Press the diameter of rope roller to be greater than wire rope diameter 5cm. This technical scheme reduces wire rope's wearing and tearing, increases wire rope's life -span, has effectually prevented the restrict emergence of phenomenon of indiscriminate row.
Description
Technical field:
This utility model relates to the crane hoisting mechanism of a kind of anticreep groove, is particularly well-suited on double girder crane use.
Background technology:
At present, China's double girder crane jack up unit is operationally, it may occur that a certain degree of be inclined transversely or longitudinally, steel wire rope so can be caused in winding groove, to depart from dislocation from reel, make groove skipping of steel rope while, the phenomenon of disorderly row's rope occurs, the abrasion making steel wire rope is accelerated, the generation of induction security incident.
Summary of the invention:
Task of the present utility model is to propose one to prevent steel wire rope from outwards beating, the crane hoisting mechanism of a kind of anticreep groove that de-groove phenomenon occurs.
Task of the present utility model so completes, it includes lifting mechanism, it is characterized in that: the two ends, side of hoisting drum are separately installed with pressure rope roller bearing, described pressure rope roller bearing is bolted on trolley frame, pressure rope roller two ends are welded with short axle, and the two ends of short axle are penetrated and fixed with pressing roller bearing of restricting by outer ring thereon in the inner ring of deep groove ball bearing.The diameter of described pressure rope roller is more than wirerope diameter 5cm.
This utility model has the effect that the technical program reduces the abrasion of steel wire rope, increases the life-span of steel wire rope, is effectively prevented the generation of disorderly row's rope phenomenon.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；Fig. 2 is pressure rope roller and pressure rope roller assembling structural representation.
Drawing illustrates: 1, trolley frame, 2, lifting speed reducing, 3, hoisting drum, 4, brake, 5, hoist power transmission shaft, 6, lifting motor, 7, wheeling mechanism, 8, pressure rope roller, 9, pressure rope roller bearing, 10, bolt, 11, outer ring, 12, deep groove ball bearing, 13, short axle.
Detailed description of the invention:
Embodiment is described in detail in conjunction with the figures above, lifting mechanism on this crane is connected with the power transmission shaft 5 that hoists by shaft coupling by lifting motor 6, the described power transmission shaft first line of a couplet that hoists is connected to shaft coupling, brake 4 connects, the upper braked wheel of brake is connected with lifting speed reducing 2 by shaft coupling, described lifting speed reducing is connected with hoisting drum 3 by gear fluted disc, steel wire rope it is wound with on hoisting drum, wheeling mechanism 7 is arranged on one end of trolley frame 1, above-described lifting mechanism and wheeling mechanism belong to prior art, the most no longer describe in detail.In order to prevent steel cable slot disengaging, the generation of disorderly row's rope phenomenon occurs, the two ends, side of hoisting drum 3 are separately installed with pressure rope roller bearing 9, described pressure rope roller bearing is fixed on trolley frame 1 by bolt 10, pressure rope roller 8 two ends are welded with short axle 13, and the two ends of short axle are penetrated and fixed with pressing roller bearing of restricting by outer ring 11 thereon in the inner ring of deep groove ball bearing 12.
The diameter of described pressure rope roller is in same height more than wirerope diameter 5cm, the described roll body center of pressure rope roller and the center of reel, and this pressure rope roll body is to be made by hot finished steel pipe, and surface slotless is conducive to stopping beating of steel wire rope.
When normally working, steel wire rope does not contacts with pressure rope roller, and when de-groove occurs in steel wire rope, pressure rope roller just forces extruded cords rope outwards to be beated so that it is steel wire rope returns to normal operation position in order, and this mechanism effectively prevent the generation of steel cable slot disengaging phenomenon.
Claims (2)
1. the crane hoisting mechanism of an anticreep groove, it includes lifting mechanism, it is characterized in that: the two ends, side of hoisting drum are separately installed with pressure rope roller bearing, described pressure rope roller bearing is bolted on trolley frame, pressure rope roller two ends are welded with short axle, and the two ends of short axle are penetrated and fixed with pressing roller bearing of restricting by outer ring thereon in the inner ring of deep groove ball bearing.
The crane hoisting mechanism of a kind of anticreep groove the most according to claim 1, it is characterised in that: the diameter of described pressure rope roller is more than wirerope diameter 5cm.
