Description
Technical field
The utility model relates to a kind of lifting means, has particularly related to a kind of winding type lifting means.
Background technology
At present, printing house's handling roller is that this mode is very inconvenient by workman's lifting roller mostly, and labor intensive production efficiency is low, and Ye You printing house adopts hydraulic efficiency equipment lifting roller, but hydraulic efficiency equipment work speed is slow, and is difficult to accurate location to the position of roller.
Summary of the invention
The utility model is not suitable with the shortcoming of need of production for roller lifting means in prior art, provides a kind of winding type gig.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Winding type gig, as shown in drawings, comprise frame, be arranged on rotatable main shaft in frame, be fixedly mounted on the reel on main shaft, the axle body of main shaft is provided with screw thread, main shaft is provided with ratchet, frame is provided with ratchet, ratchet both sides are respectively equipped with left friction lining and right friction lining, sleeve is provided with on the left of left friction lining, nut is provided with on the right side of right friction lining, main shaft is successively through sleeve, left friction lining, ratchet, right friction lining and nut, nut is threaded connection outside axle body, the head of main shaft is provided with the first torsion spring and end cap, the spindle nose of main shaft is through the first torsion spring, first torsion spring two ends are stretched in nut and end cap respectively, end cap is fixed on spindle nose.
As preferably, also comprise axle sleeve, ratchet and axle sleeve interference fit.Axle sleeve plays the effect that protection main shaft is not worn.
As preferably, also comprise rocking bar, rocking bar is fixedly connected with nut or rocking bar and nut are integrated.People's rotating rocker, rocking bar drives nut rotation.
As preferably, described ratchet in frame, is provided with the second torsion spring by hinge outside bearing pin, the second torsion spring two ends are stretched in frame and ratchet respectively.Check pawl, prevents ratchet from turning round.
As preferably, also comprise bracket, bracket is provided with the pallet of arc-shaped, and bracket is provided with pulley, and reel is wound with steel wire, and after steel wire strides across pulley, one end is fixed in frame.The pallet of arc-shaped is used for placing roller, and pulley is movable pulley, arranges movable pulley, can be laborsaving.
As preferably, bottom frame, be provided with roller.It is removable that roller afer bay is set.
When promoting roller, workman's rotating rocker, rocking bar drives nut rotation, because the axle body of main shaft is provided with screw thread, have the axial motion towards right friction lining direction while nut rotation, nut compresses right friction lining, ratchet, left friction lining and sleeve, and extremely now nut is limited towards the axial motion in right friction lining direction, because when this person shakes rocking bar, nut can not rotate again, now main shaft rotates along with the rotation of rocking bar.When roller is promoted to desired location, decontrol rocking bar, nut is subject to the effect of the first torsion spring, and limiting rotation can not be reversed, and therefore left friction lining, ratchet, right friction lining are still compacted, therefore do not relatively rotate between ratchet and main shaft.Now ratchet limits the rotation of ratchet, does not rotate between ratchet and main shaft, therefore only decontrols rocking bar, and roller can not fall.With counter-rotation rocking bar during lifting roller, now nut has the retrogressing of slight distance in the axial direction, and left and right friction lining is separated with ratchet, and ratchet and main shaft can relatively rotate, and roller can fall.The utility model, owing to have employed above technical scheme, reduces roller handling intensity, improves safety, prevent from breaking roller, substantially increase work efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Embodiment 1
Winding type gig, as shown in drawings, comprise frame 3, be arranged on rotatable main shaft 1 in frame 3, be fixed on the reel 2 on main shaft 1, the axle body 12 of main shaft 1 is provided with screw thread, main shaft 1 is provided with ratchet 6, frame 3 is provided with ratchet 5, ratchet 6 both sides are respectively equipped with left friction lining 14 and right friction lining 7, sleeve 15 is provided with on the left of left friction lining 14, nut 8 is provided with on the right side of right friction lining 7, main shaft 1 is successively through sleeve 15, left friction lining 14, ratchet 6, right friction lining 7 and nut 8, nut 8 is threaded connection on axle body 12, the head of main shaft 1 is provided with the first torsion spring 10 and end cap 9, the spindle nose 11 of main shaft 1 is through the first torsion spring 10, first torsion spring 10 two ends are stretched in nut 8 and end cap 9 respectively, end cap 9 is fixed on spindle nose 11.
When promoting roller, workman's rotating rocker 19, rocking bar 19 drives nut 8 to rotate, because the axle body 12 of main shaft 1 is provided with screw thread, nut 8 has the axial motion towards right friction lining 7 direction while rotating, nut 8 compresses right friction lining 7, ratchet, left friction lining 14 and sleeve 15, and extremely now nut 8 is limited towards the axial motion in right friction lining 7 direction, because when this person shakes rocking bar 18, nut 8 can not rotate again, now main shaft 1 rotates along with the rotation of rocking bar 18.When roller is promoted to desired location, decontrol rocking bar 19, nut 8 is subject to the effect of the first torsion spring 10, and limiting rotation can not be reversed, and therefore left friction lining 15, ratchet 6, right friction lining 7 are still compacted, therefore do not relatively rotate between ratchet 6 and main shaft 1.Now ratchet 5 limits the rotation of ratchet 6, does not rotate between ratchet 6 and main shaft 1, and therefore only decontrol rocking bar 19, roller can not fall.
Also comprise axle sleeve 13, ratchet 6 and axle sleeve 13 interference fit.Axle sleeve 13 plays the effect that protection main shaft 1 is not worn.
Also comprise rocking bar 19, rocking bar 19 is fixedly connected with nut 8 or rocking bar 19 is integrated with nut 8.People's rotating rocker 19, rocking bar 19 drives nut 8 to rotate.
Described ratchet 5 by hinge, is provided with the second torsion spring 4, second torsion spring 4 two ends and stretches into respectively in frame 3 and ratchet 5 in frame 3 outside bearing pin.Prevent ratchet from turning round.
Also comprise bracket 18, bracket 18 is provided with the pallet 21 of arc-shaped, and bracket 18 is provided with pulley 17, reel 2 is wound with steel wire 16, and after steel wire 16 strides across pulley 17, one end is fixed in frame 3.Pallet 21 is used for placing roller, and pulley 17 is movable pulley, arranges movable pulley, can be laborsaving.
Roller 20 is provided with bottom frame 3.It is removable that roller 20 afer bay 3 is set.
Embodiment 2
When roller is promoted to desired location, decontrol rocking bar 19, nut 8 is subject to the effect of the first torsion spring 10, and limiting rotation can not be reversed, and therefore left friction lining 15, ratchet 6, right friction lining 7 are still compacted, therefore do not relatively rotate between ratchet 6 and main shaft 1.Now ratchet 5 limits the rotation of ratchet 6, does not rotate between ratchet 6 and main shaft 1, and therefore only decontrol rocking bar 19, roller can not fall.
Embodiment 3
With counter-rotation rocking bar 19 during lifting roller, now nut 8 has the retrogressing of slight distance in the axial direction, and left and right friction lining is separated with ratchet 6, and ratchet 5 and main shaft 1 can relatively rotate, and roller can fall.
Because being provided with movable pulley and rocking bar, therefore this device is all comparatively laborsaving when lifting and let-down roller.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
