Description

Rope processing device

Technical field

The utility model relates to a kind of rope press device, particularly relates to a kind of rope processing device that is used for winch.

Background technology

At present, in the engineering construction process, winch frequently obtains using, but " disorder cable " phenomenon that entanglement is twined appears in steel rope on the winch often in use, the use of rope processing device is exactly for the roll extrusion alignment is wrapped in steel rope on the winch cylinder, to solve " disorder cable " problem.As shown in Figure 1, present existing winch rope processing device 11 is a symmetrical structure, comprise a pair of spring 1 that is suspended on the cylinder frame, be connected to the horizontal spring pull bar 2 of two springs, 1 end, vertically be installed in a pair of arm-tie 5 on the spring pull bar 2, be installed in a horizontal rotating shaft 4 on two arm-ties, 5 tops and by the sleeve 3 of bearing installation in rotating shaft 4, this sleeve 3 can freely rotate in rotating shaft 4.Fig. 2 is the working state schematic representation of this rope processing device 11, in conjunction with Fig. 1 as seen, the part of these rope processing device 11 roll extrusion steel ropes is cylindrical sleeves 3 of integrative-structure, though it can solve steel rope " disorder cable " problem, but as shown in Figure 2, steel rope is in winding process, the new steel rope 12 that twines is pressed on the sleeve 3, because the existence of spring 1, make steel rope 12 perks that sleeve 3 newly twined together with whole rope processing device 11 and run-off the straight, the pressure of sleeve 3 other ends is concentrated and is acted on the steel rope 13 of opposite end, and the rotation in rotating shaft 4 along with the continuous winding of steel rope of sleeve 3 this moment is worn steel rope 13 places of opposite end, when the winch long-time running, steel rope will be subjected to more serious wearing and tearing, influence its service life.

The utility model content

The technical matters that the utility model solves provides a kind of rope processing device that alleviates steel rope abrasion greatly.

Rope processing device of the present utility model, comprise a pair of spring, on even keel be connected the spring pull bar of described two spring ends, relatively be installed in a pair of arm-tie, on even keel on the described spring pull bar be installed on described two arm-ties rotating shaft and by the sleeve of bearing installation in described rotating shaft, described rotating shaft two ends extend to the outside of the described arm-tie of this side respectively, form cantilever beam, pass through secondary sleeve of bearing installation on the described cantilever beam of every side, described secondary sleeve all is truncated cone-shaped, and the bottom surface that its diameter is little is positioned at the described cantilever beam outside.

Rope processing device of the present utility model, wherein said rotating shaft is provided with the shaft shoulder near the position of the described arm-tie in both sides, and make the diameter of the diameter of described cantilever beam less than the described shaft shoulder, the through hole that described arm-tie is installed described cantilever beam is provided with a sleeve, the described bearing and the shaft shoulder abut against the both sides of described sleeve respectively, and the outside of described bearing is provided with trip ring.

Rope processing device of the present utility model, wherein the bearing on each described cantilever beam is two, is provided with pad between described two bearings.

Rope processing device of the present utility model, be improved to separate three sections by part by one section cylindrical sleeve of the prior art with the roll extrusion steel rope, and the secondary sleeve at two ends made truncated cone-shaped, secondary sleeve is contacted with the steel rope generation line that newly is involved in, and reduce to the perk degree of cylindrical sleeve in stage casing and even whole rope processing device minimum, greatly reduce the degree of the steel rope steel rope perk that rope processing device newly is involved in winding process, thereby alleviated the degree of wear of steel rope, prolonged its service life.

The specific embodiment

With reference to figure 4 and Fig. 5, the utility model rope processing device one embodiment 14 comprises that a pair of spring 1, on even keel are connected the spring pull bar 2 of described two springs 1 end, relatively are installed in a pair of arm-tie 5, on even keel on the described spring pull bar 2 and are installed in the rotating shaft 4 on described two arm-ties 5 and are installed in sleeve 3 in the rotating shaft 4 by bearing 8, rotating shaft 4 two ends extend to the outside of this layback plate 5 respectively, form cantilever beam 9, by bearing 7 a secondary sleeve 6 is installed on every side cantilever beam 9, secondary sleeve 6 all is truncated cone-shaped, and the bottom surface that its diameter is little is positioned at described cantilever beam 9 outsides.Two arm-ties 5 are installed on the winch frame by the bolt in the through hole 20 mounted thereto.

On the position of rotating shaft 4, be respectively equipped with the shaft shoulder near both sides arm-tie 5, and make the diameter of the diameter of cantilever beam 9 less than the described shaft shoulder, the through hole that arm-tie 5 is installed cantilever beam 9 is provided with a sleeve 18, the described bearing 7 and the shaft shoulder abut against the both sides of this sleeve 18 respectively, are provided with trip ring 16 in the outside of bearing 7.

Bearing 7 on each cantilever beam 9 is two, is provided with pad 17 between this two bearing 7.

Below in conjunction with Fig. 4 and Fig. 5 and with reference to figure 3, the working process and the principle of work of rope processing device is described.When winch was worked, the steel rope on it constantly was wrapped on the cylinder, and 14 roll extrusion of rope processing device that are positioned at the cylinder top are being positioned on the steel rope that constantly twines on the cylinder, to prevent it " disorder cable " phenomenon that entanglement is twined take place.When the steel rope 15 of new winding formed new layer of steel wire rope, because the secondary sleeve 6 that is positioned on the rope processing device 14 left side cantilever beams 9 is the outside truncated cone-shaped of small end, linearities took place with the new steel rope that twines 15 and contact in it, and have avoided the perk of secondary sleeve 6 substantially.When the steel rope 15 of new winding is rolled up below to rope processing device 14 sleeves 3, because the length of sleeve 3 shortens greatly with respect to length of the prior art, thereby its degree by steel rope 15 perks is greatly diminished, the steel rope that is positioned at sleeve 3 other ends is also correspondingly reduced greatly owing to the perk of sleeve 3 is rotated extruding and the worn-down degree takes place, thereby prolonged the service life of whole steel rope.The through hole of cantilever beam 9 being installed at arm-tie 5 is provided with sleeve 18, makes the secondary sleeve 6 of sleeve 3 and both sides all and between the arm-tie 5 form the gap, thereby the secondary sleeve 6 of sleeve 3 and both sides all can be rotated flexibly.Two springs 1 are hung in the both ends of spring pull bar 2, and by baffle plate 19 edge sealing, come off to prevent spring 1.
