Detailed description of the invention
Embodiment 1
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in figs. 1-7, a kind of Lift Mechanism in Power Hoist rope press device, comprise four pieces of stay bearing plates, 5, four support link, 4, four connecting angles 8 and a pivot shaft 9, described stay bearing plate 5 top is provided with a hole, described support link 4 is " L " type structure, the upper end of support link 4, corner and lower end are all provided with a hole, and connecting angle 8 is provided with a hole.
Four pieces of described stay bearing plate 5 shapes are in a row, every block stay bearing plate 5 be welded on Lift Mechanism in Power Hoist on the underframe of reel 2 side by a connecting angle 8.
The hole of Kong Yuyi the support link corner at every block stay bearing plate 5 top is corresponding, support link 4 is connected with stay bearing plate 5 with the hole at stay bearing plate 5 top through the hole of support link 4 corner by pivot shaft 9, the diameter of described pivot shaft 9 is less than the diameter in the hole of support link 4 corner, to ensure that support link 4 can be rotatably mounted on pivot shaft 9; Pivot shaft 9 two ends to be fixed in frame and to be provided with spring cotter, prevent pivot shaft 9 from rotating in use.
Be installed with roller axle 11 in the upper end hole of described support link 4, and by flat key 10, roller axle 11 be fixed in the upper end hole of support link 4, prevent roller axle 11 from rotating in use.
Roller axle 11 is divided five sections by described four support link 4, and every section of roller axle sleeve has pressure rope roller 3; Described pressure rope roller is against on the steel rope 1 of winding on reel 2; The rounded structure in described support link 4 upper part, the diameter of the upper part of support link 4 is less than the external diameter of pressure rope roller 3, for making support link 4 upper part not by steel rope abrasion.
As shown in Figure 6, the pressure rope roller being enclosed within two ends in roller axle 11 is tapered rollers, smooth to ensure volume layer transition.
Described connecting angle 8 is connected with the lower end of support link 4 by spring 6.Described spring 6 is the spring of band adjusting screw, and spring 6 crotch end connects on the hole of described support link 4 lower end, the thread end of spring 6 by fastening nuts on angle steel 8.Specifically the thread end of spring 6 is through behind the hole on angle steel 8, adopts the thread end of nut screwing clamping spring 6.
During installation, first four pieces of stay bearing plates 5 and four connecting angles 8 are welded on lifting mechanism on the underframe of reel 2, the upper end hole again roller axle 11 being each passed through pressure rope roller 3 endoporus and support link 4 makes it to be cascaded, with flat key 10, roller axle 11 and support link 4 junction are fixed, prevent roller axle 11 from rotating with pressure rope roller 3; And then get up and the hole passed on stay bearing plate 5 top with the hole hinge joint of pivot shaft 9 through support link 4 corner, pivot shaft 9 is made to be fixed on stay bearing plate 5, support link 4 can be rotatably mounted on pivot shaft 9, and prevent pivot shaft 9 from rotating at the first-class spring cotter in pivot shaft 9 two ends; Then with the spring 6 of band adjusting screw, band crotch end hook is lived on the lower stomidium of connecting rod 4, the threaded other end is fastening through the hole nut 7 on connecting angle 8; Finally steel rope 1 is applied certain tension filament winding on reel 2, make pressure rope roller 3 under the pulling force of the spring 6 of band adjusting screw by the screw rod on regulating spring 6 like this, pressure rope roller 3 is made to compress the steel rope of winding all the time according to lever principle, by the pressure of adjustment pressure rope roller 3 pairs of steel ropes, disorder cable phenomenon can be avoided, thus can effectively ensure steel rope marshalling.
