Detailed description of the invention
below in conjunction with accompanying drawing, technical scheme of the present invention is further elaborated.
a kind of building hoist roller anti-drop device, this elevator comprises the cage girder 100 that arranges along the vertical direction and bogie girder (not shown), to be arranged on cage girder 100 and bogie girder and the multiple side wheels 3 be pressed on elevator standard knot side respectively.Shown in Fig. 1, Fig. 2, Fig. 5, this cage girder 100 is all have employed interior lipped channel to make with bogie girder, this cage girder 100 and bogie girder all offer hole 1, also be installed with a stay bearing plate vertically arranged 2 in this hole 1, this side wheel 3 is arranged between the front side plate 11 of stay bearing plate 2 and hole 1.In this example, this stay bearing plate 2 is welded in hole 1 by the mode of welding.By arranging hole 1, adopting inner support formula installation side roller 3, effectively prevent in prior art the side wheel 3 adopting suspension type to install, when coming off, side wheel 3 falls the accident generation causing injuring by a crashing object people.
shown in Fig. 3, Fig. 4, this anti-drop device 200 comprises the dowel disc 7 be located at along the eccentric shaft 4 between the front side plate 11 self being axially installed in stay bearing plate 2 and hole 1, the antifriction-bearing box 6 be set on eccentric shaft 4, fixed cover on eccentric shaft 4 one end, this eccentric shaft 4 and side wheel 3 are closely arranged mutually with the inner ring madial wall of antifriction-bearing box 6, outer ring lateral wall respectively, and dowel disc 7 is fixedly connected with the front side plate 11 of stay bearing plate 2 or hole 1.The front side plate 11 of stay bearing plate 2 and hole 1 all offers the axis hole 20 for setting-up eccentricity axle 4, and eccentric shaft 4 is fixed by jam nut and biside plate through after front side plate 11 and the axis hole 20 on stay bearing plate 2 of hole 1 successively.
here, this eccentric shaft 4 is gone back fixed cover and be provided with eccentric bushing 5 with the level, shown in Fig. 3, Fig. 4, the outer peripheral sidewall of this eccentric bushing 5 is closely arranged mutually with the inner ring madial wall of antifriction-bearing box 6, and the endoporus of this dowel disc 7 is closely arranged mutually with the outer peripheral sidewall of the step on this eccentric bushing 5.By arranging eccentric bushing 5 with the level, while dowel disc 7 is fixing, also can be fixed by eccentric shaft 4, efficiently avoid in elevator duty process, eccentric shaft 4 occurs to loosen, and the phenomenon causing side wheel 3 to come off occurs.In this example, this step design has become tetragonal step, and correspondingly, the endoporus of this dowel disc 7 is also in square, and such design, makes to be connected between dowel disc 7 with eccentric shaft 4 more tight, stopped the phenomenon generation that eccentric shaft 4 rotates.In order to prevent antifriction-bearing box 6 from longitudinal travel occurring, here, this anti-drop device 200 also comprises and is set on eccentric bushing 5, is positioned at two collars 8 of the axial both sides of antifriction-bearing box 6.
here, this dowel disc 7 fixed cover is located on one end of close stay bearing plate 2 side of eccentric shaft 4, and this dowel disc 7 offers knock hole 70, stay bearing plate 2 also offers the dowel hole 21(that matches with knock hole 70 see shown in Fig. 2, Fig. 5).When adjusting the position of eccentric shaft 4, this dowel disc 7 is fixedly connected by nut locking and stay bearing plate 2 through after knock hole 70, dowel hole 21 by locating dowel pin.
knock hole 70 on this dowel disc 7 has multiple, and all knock holees 70 are distributed on dowel disc 7 along same circumferencial direction uniform intervals.In the process that eccentric shaft 4 position is adjusted, because fine setting causes not necessarily overlapping completely between the knock hole 70 on dowel disc 7 and the dowel hole 21 on stay bearing plate 2, locating dowel pin is caused to insert, here, this stay bearing plate 2 is at least provided with two dowel holes 21, two dowel holes 21 are all positioned on same pitch circle, and the center of circle of this pitch circle and the circumference center of circle at knock hole 70 place are in the same horizontal line and the circle diameter at this joint circle diameter and knock hole 70 place is consistent.As overlapped completely between the knock hole of on dowel disc 7 70 with the dowel hole of on stay bearing plate 2 21, and when dowel disc 7 having a knock hole 70 overlap completely with another dowel hole 21 on stay bearing plate 2, then meet location needs, only by locating dowel pin through knock hole 70, dowel hole 21, then need be locked on stay bearing plate 2 by nut.Like this, namely can not rotate again after dowel disc 7 is located by bearing pin, and eccentric shaft 4 is by step and dowel disc 7 phase compact siro spinning technology, thus prevents the rotation of eccentric shaft 4, serve the location of anti-drop device 200 integral position, make elevator smooth operation.
adopt above-mentioned design, thoroughly solve the safety hazard that on building hoist driver train and cage girder 100, side wheel 3 is installed, have employed inner support formula installation side roller 3, effectively prevent side wheel 3 to come off brought danger, completely solve the loosening problem of the fastening rear instability of eccentric shaft 4 by arranging dowel disc 7 simultaneously, and only have the scheme adopting the cage girder 100 of interior crimping channel steel support and bogie girder could realize above-mentioned inner support formula installation side roller 3.
above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
