Abstract
The utility model discloses a swing arm tower machine amplitude changing device arranges knot and constructs, assembly pulley (4) on top ping lift, amplitude changing device, top of the tower, become a width of cloth assembly pulley (2), jib loading boom pull rod (1), still including the row who installs at the amplitude changing device side restrict pulley (6), top ping lift draw forth the back by the amplitude changing device reel, jib loading boom (3) are connected behind a width of cloth assembly pulley (2), jib loading boom pull rod (1) with becoming in pile warp assembly pulley (4) of arranging on rope pulley (6), the top of the tower in proper order, this rows rope pulley (6) is through axial motion adjustment top ping lift's the angle of receiving and releasing, the phenomenon that can avoid wire rope the disorder cable to appear in the use, knot, reducible wire rope's of while change frequency, reduction use cost.
Description
Technical field
The utility model relates to a kind of row's rope structure, relates in particular to a kind of movable arm tower crane jib lubbing mechanism row rope structure.
Background technology
Existing whip-typed tower crane counter-jib jib lubbing mechanism steel wire rope is introduced directly into assembly pulley and luffing assembly pulley on tower top, and luffing assembly pulley is linked together after being drawn by the reel in mechanism, thereby realizes the effective control to the crane arm elevation angle. This version is directly introduced assembly pulley on tower top and cannot ensure the folding and unfolding angle of steel wire rope because of steel wire rope, in use very easily occurs the phenomenon of disorder cable, knotting, and easily causes the mutual crimp of steel wire rope, and wearing and tearing, cause waste in advance. Specifically there is following technical disadvantages:
1, variable-amplitude steel wire rope sorts disorderlyly on reel, is prone to the phenomenon of disorder cable, knotting in use procedure, needs operating personnel often reel to be checked, corrected, and affects the service efficiency of tower machine, and can increase labor management cost.
2, steel rope abrasion is very fast, strengthens with changing frequency. Because this structure is in use prone to the phenomenon that steel wire rope mutually pushes, is out of shape, cause steel wire rope to be scrapped in advance, increase the replacement frequency of steel wire rope, cause use cost to increase and waste.
Summary of the invention
For above-mentioned existing technical problem, the utility model provides a kind of movable arm tower crane jib lubbing mechanism row rope structure, with in the use procedure of movable arm type tower machine, ensure the rope stretching angle of variable-amplitude steel wire rope, avoid the phenomenon of variable-amplitude steel wire rope disorder in use procedure, reduce the replacement frequency of variable-amplitude steel wire rope, improve service efficiency.
For achieving the above object, the utility model provides a kind of movable arm tower crane jib lubbing mechanism row rope structure, comprises assembly pulley, luffing assembly pulley, crane arm pull bar on variable-amplitude steel wire rope, jib lubbing mechanism, tower top, also comprises the row's rope pulley that is arranged on jib lubbing mechanism side; After described variable-amplitude steel wire rope is drawn by jib lubbing mechanism reel, the assembly pulley on pile warp row rope pulley, tower top is connected crane arm with after luffing assembly pulley, crane arm pull bar successively, and this row's rope pulley is adjusted the folding and unfolding angle of variable-amplitude steel wire rope by axially-movable. Thereby realize the rule compositor of steel wire rope on reel, reduce the wearing and tearing of steel wire rope, ensure its service life, save use cost.
Further, described jib lubbing mechanism is arranged on counter-jib.
The utility model is by increasing row's rope pulley at jib lubbing mechanism side, steel wire rope is wound into the pulley combination luffing assembly pulley on tower top after arranging rope pulley, in use, row's rope pulley is by sliding axially to ensure being aligned on mechanism's reel of steel wire rope angle rule according to the rules, thereby has following advantage:
1, prevent that disorder cable, knotting phenomenon from appearring in steel wire rope. This structure is in jib lubbing mechanism use procedure, and row's rope sheave is by moving axially to adjust, ensure steel wire rope angle, and guarantee steel wire rope can, according to the arrangement of the mode of setting rule on reel, avoid occurring the phenomenon of disorder cable, knotting.
2, reduce the replacement frequency of steel wire rope, reduce use cost. By effective control that steel wire rope is used, avoid the extrusion abrasion of steel wire rope, ensure the service life of steel wire rope, reduce use cost.
Brief description of the drawings
Fig. 1 is movable arm tower crane jib lubbing mechanism row rope structure schematic diagram in prior art;
Fig. 2 is structural representation of the present utility model;
In figure: 1, crane arm pull bar, 2, luffing assembly pulley, 3, crane arm, 4, assembly pulley on tower top, 5, counter-jib, 6, row's rope pulley.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 2, the utility model comprises assembly pulley 4, luffing assembly pulley 2, the crane arm pull bar 1 on variable-amplitude steel wire rope, jib lubbing mechanism, tower top, also comprise the row's rope pulley 6 that is arranged on jib lubbing mechanism side, after described variable-amplitude steel wire rope is drawn by jib lubbing mechanism reel, after row's rope pulley 6, be connected to assembly pulley 4 and the luffing assembly pulley 2 on tower top, connect crane arm finally by crane arm pull bar 1. Row's rope pulley 6 is adjusted variable-amplitude steel wire rope folding and unfolding angle by axially-movable, realizes the rule compositor of variable-amplitude steel wire rope on reel.
When enforcement, by increase row's rope pulley 6 at jib lubbing mechanism side, steel wire rope is connected to the assembly pulley 4 on tower top after arranging rope pulley 6, in ensureing variable-amplitude steel wire rope folding and unfolding angle, can avoid steel wire rope in use to occur the phenomenon of disorder cable, knotting, can reduce the replacement frequency of steel wire rope, reduce use cost simultaneously.
By applying this technology, not only ensure the easy for installation, quick of XGTL160 variable-amplitude steel wire rope, arrange rope sheave by moving axially the effective use angle that ensures variable-amplitude steel wire rope simultaneously, avoid variable-amplitude steel wire rope to occur the phenomenon of disorder cable, knotting, also the steel wire rope wearing and tearing that are squeezed have been avoided, effectively ensure the service life of steel wire rope, can effectively save use cost. Meanwhile, the also design of other products is had to important reference value and using value.
