Description
Technical field
It the utility model is related to elevators field, and in particular to a kind of elevator car overhead sheave.
Background technology
Present skyscraper is more and more, and for elevator into essential means of transport, elevator safety is also essential, needs
Inspection and maintenance periodically is carried out to elevator, elevator car overhead sheave carries the total weight of elevator, also concerns all seating elevators
Life security, existing elevator car overhead sheave is simple in construction, and steel wire rope pulls repeatedly easily makes top wheel deformation and to groove and steel
Cord produces abrasion, needs during replacing to change whole top wheel, and replacement cost is big, also very inconvenient during replacing.
Utility model content
In order to solve above-mentioned problem, the utility model provides a kind of elevator car overhead sheave.
The utility model is to be achieved through the following technical solutions：
A kind of elevator car overhead sheave, including sleeve, sleeve outer end be fixed with its integrally formed disk, be fixed with disk
It is multiple to surround sleeve array with its integrally formed supporting plate, the supporting plate and be secured to connect, the supporting plate both sides
Groove is arranged with, the outer ring of annular is socketed with the outside of disk, multiple floors corresponding with groove, outer snare are fixed with outer ring
Rear bearing sheet is inserted between two floors and is bonded with it on disk, and the floor and supporting plate of disk both sides are by bolt and certainly
Split nut is fixed, and outer ring side wall is provided with multiple annular grooves, and the annular groove madial wall edge sets chamfering.
Preferably, the thickness of the supporting plate is 20-30mm.
Preferably, the thickness of the floor is 10-20mm.
Preferably, the annular groove width is 16mm.
Compared with prior art, the beneficial effects of the utility model are：The utility model is designed reasonably, make simply,
The madial wall edge of annular groove is set as chamfering, and chamfering is round and smooth to be damaged to steel wire rope, makes the more robust elevator of steel wire rope more
Safety, supporting plate can externally be enclosed and played a supporting role, and outer ring is not easy deformation, increase durability degree, outer ring and inner disc are detachable
Connection, only need during damage to change outer ring, it is convenient to change, cost-effective.

In figure：Sleeve 1, disk 2, supporting plate 3, groove 4, outer ring 5, floor 6, bolt 7, self-locking nut 8, annular groove 9, fall
Angle 10.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, a kind of elevator car overhead sheave, including sleeve 1, the outer end of sleeve 1 be fixed with
Its integrally formed disk 2, it is fixed with disk 2 and multiple surrounds sleeve 1 with its integrally formed supporting plate 3, the supporting plate 3
Array simultaneously is secured to connect, and the both sides of supporting plate 3 are arranged with groove 4, and the outside of disk 2 is socketed with the outer ring 5 of annular, outside
Multiple floors 6 corresponding with groove 4 are fixed with circle 5, outer ring 5 is enclosed on rear bearing sheet 3 on disk 2 and inserted between two floors 6
And be bonded with it, the floor 6 of the both sides of disk 2 is fixed with supporting plate 3 by bolt 7 and self-locking nut 8, and the side wall of outer ring 5 is provided with more
Individual annular groove 9, the madial wall edge of annular groove 9 set chamfering 10.
The thickness of the supporting plate 3 is 20-30mm.
The thickness of the floor 6 is 10-20mm.
The width of annular groove 9 is 16mm.
Operation principle：It the utility model is related to a kind of elevator car overhead sheave, more steel wire ropes be placed on annular groove 9 during use
It is interior, the purpose taken turns rolling and reach elevator lifting in top is pulled using steel wire rope, the madial wall edge of annular groove 9 is set as chamfering 10, falls
Angle is round and smooth to be damaged to steel wire rope, make the more robust elevator of steel wire rope safer, it is necessary to by self-locking nut 8 when changing top wheel
Back out, take out outer ring 5 after removing bolt 7, groove 4 is directed at all corresponding insertions of floor 6 when changing outer ring 5, reuses spiral shell
Bolt 7 fixes supporting plate 3 and floor 6, finally locks self-locking nut 8, and supporting plate 3 can play a supporting role to outer ring 5, make outer ring
5 are not easy deformation, increase durability degree, then steel wire rope is placed in annular groove 9, complete the replacing maintenance of top wheel, outer ring 5 is with inner disc
It is detachably connected, only needs during damage to change outer ring, it is convenient to change, cost-effective.
General principle, principal character and advantage of the present utility model has been shown and described above.The technical staff of the industry
It should be appreciated that the utility model is not restricted to the described embodiments, the simply explanation described in above-described embodiment and specification is originally
