Centralized rotation pay off rack
Technical field
The utility model relates to the pay off rack that is applied in the cable production, a kind of pay off rack that is mainly used in heavy in section, the stranded stranding of length power cable of more specifically saying so.
Background technology
The disc type cabler rotation pay off rack that uses at present is the distributed structure that adopts as shown in Figure 1, each drum shown in Fig. 1, comprise that A drum 11, B drum 12, C drum 13 and D drum 14 are on same layer plane, promptly distribute by front, rear, left and right on the ground, this drum distribution form floor space is big, produce line length, twisting point O is far away, therefore prolong twisted wire speed, greatly limited the raising of production efficiency, moreover, the pay off rack structure of this each drum of distributed structure is formed complexity, cost is high.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, provides that a kind of floor space is little, cost is low, structure is formed simple centralized rotation pay off rack, with the stranded quality that improves core, enhance productivity.
The utility model technical solution problem adopts following technical scheme.
The design feature of the centralized pay off rack of the utility model is that described pay off rack is set is to concentrate on to have the upper strata frame parallel to each other and a double-deck shelf structure of lower floor's frame on the same axial location; Each bobbin loader distributes respectively on upper strata frame and the lower floor's frame.
The design feature of the centralized pay off rack of the utility model also is:
In described upper strata frame and lower floor's frame, be that line outlet with place one deck is that the axis of center, each bobbin loader is fan-shaped distribution mutually with each bobbin loader in one deck frame.
Each bobbin loader in the different layers frame is not on same perpendicular.
In described upper strata frame and lower floor's frame, be separately positioned on two bobbin loaders, the angle between two bobbin loader horizontal axiss on the frame of upper strata is 14 °; Angle between two bobbin loader horizontal axiss in lower floor's frame is 32 °.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model is concentrated drum spatially and is arranged, has dwindled stranded distance, has reduced the pitch that produces owing to distance and the error at phase angle, has improved stranded quality.
2, the utility model can improve hauling speed owing to the concentrated setting of drum, and reduces parking rate, thereby enhances productivity.
3, the utility model has shortened the line length of cable twisting technology greatly, thereby reduces to take up an area of.
4, the utility model is simplified the equipment of unwrapping wire workshop section greatly, thereby reduces cost.

Number in the figure: 1 front support bracket, 2 rear support brackets, a left side, 3 upper stratas bobbin loader, the right bobbin loader in 4 upper stratas, 5 lower floors left side bobbin loader, the right bobbin loader of 6 lower floors, 7 braking system, 8 chain drive systems, 9 guide rollers, 10 clutches
Embodiment
Pay off rack is set is to concentrate on and have the upper strata frame parallel to each other and a double-deck shelf structure of lower floor's frame on the same axial location; Each bobbin loader distributes respectively on upper strata frame and the lower floor's frame, forms the spatial distribution of bobbin loader; In upper strata frame and lower floor's frame, with each bobbin loader in one deck frame is that line outlet with place one deck is that the axis of center, each bobbin loader is fan-shaped distribution mutually, each bobbin loader in the different layers frame is not on same perpendicular, and this form can effectively be avoided the interference each other of each bobbin loader.
Referring to Fig. 2, Fig. 3 and Fig. 4, in the present embodiment, it is the double-decker with upper strata frame and lower floor's frame that is made of jointly front support bracket 1 and rear support bracket 2 that pay off rack is set, and the angle of the horizontal axis between the right bobbin loader 4 of upper strata left side bobbin loader 3 in the frame of upper strata and upper strata is set to 14 °; The angle of the horizontal axis between the right bobbin loader 6 of lower floor's left side bobbin loader 5 in lower floor's frame and lower floor is set to 32 °, forms two lower floor's bobbin loaders and two dislocation of lower floor's bobbin loader on perpendicular.So both guarantee the fixed position of payingoff disk frame, guaranteed payingoff disk frame mutually noninterfere when independent rotation again;
In concrete the enforcement, on front support bracket 1, the line outlet place that is positioned at every payingoff disk frame is equipped with guide roller 9, guide roller 9 can adjust the line angle degree along with the swing of cable, so that stranded cable moves towards smooth, guarantee that the line of being put passes through guide roller 9 junctions to twisting point 0, meets the stranding requirement.
In the present embodiment, pay off rack is by a main motor-driven, carry out transmission by the earth's axis, again by sprocket wheel and bevel gear assembly on the sprocket wheel drive axle of carrier pulley that is contained on the earth's axis, be passed to the clutch 10 of pay off rack rear end by the bevel gear on sprocket wheel and the bevel gear assembly, drive each bobbin loader rotation by clutch 10, realize back twist; The corresponding structure setting comprises braking system 7 and chain drive system 8, rotation that each bobbin loader both can make identical rotation direction simultaneously is set to carry out back twist twisted cable line, also can maintain static, and not back twist twisted cable line is finished the stranded of synteny not.
If strand system quad all rotates four payingoff disk frames by the clutch by clutch; Strand system three heart yearns are then thrown off wherein a pair of clutch in this way, and the payingoff disk frame on the correspondence position is not rotated, to satisfy the requirement of three heart yearns; Equally also can realize the stranding of two heart yearns.
