Abstract

The utility model discloses an elevator rope pulley comprising a plurality of rope pulley units which can be coaxially arranged, wherein a rope groove, which extends in circumferential direction, is formed on an outer peripheral face of each rope pulley unit, and the plurality of rope pulley units are detachably connected with each other. On the rope pulley which is formed by combining the plurality of rope pulley units coaxially arranged together, if one rope groove breaks down due to abrasion, the corresponding rope pulley unit can be replaced with a new rope pulley unit without replacing the whole rope pulley, so that the use cost of the rope pulley is reduced. Furthermore, the number of the steel wire ropes usually varies with the load of an elevator car, so that if the numbers of the steel wire ropes are needed to increase, the numbers of the rope grooves on the rope pulley are also accordingly needed to increase; for an integrated rope pulley mentioned in the background technology, if the numbers of the rope grooves are needed to increase, a new integrated rope pulley is needed to use; and for the elevator rope pulley provided by the utility model, only new rope pulley units are needed to be added on the basis of the rope pulley. Therefore, the rope pulley provided by the utility model can add or reduce the rope pulley units as required, so as to achieve the addition or reduction of the numbers of the rope grooves, and also can lower the cost.

Description

The elevator rope sheave

Technical field

The utility model relates to the elevator rope sheave.

Background technology

Existing elevator rope sheave, usually adopt a single-piece rope sheave, offer the grooving that circumferentially extend on a plurality of edges on the outer peripheral face of rope sheave, many steel ropes are when walking around rope sheave, and steel cable is arranged in the grooving, and steel rope is in the process that drives the lift car lifting, mobile can the wear and tear grooving of steel rope in grooving, break down as long as there is a grooving to be worn, then must will change whole rope sheave, cause the use cost height of rope sheave.

Summary of the invention

The purpose of this utility model provides the elevator rope sheave that a plurality of rope sheaves unit arranged in co-axial alignment forms, and wherein each rope sheave unit has a grooving.

For achieving the above object, the technical solution adopted in the utility model is: the elevator rope sheave, but the rope sheave unit that comprises a plurality of arranged in co-axial alignment offers the grooving that circumferentially extend on an edge on the outer peripheral face of each described rope sheave unit, a plurality of described rope sheaves removably connect between the unit mutually.

Preferably, each described rope sheave unit offers a plurality of perforation that are connected on the radial surface between centre hole and the described grooving, described a plurality of connection perforation is provided with separately along the circumferential direction of described rope sheave unit, when between described a plurality of rope sheaves unit, being connected, adjacent two described rope sheave unit same axis are adjacent to, passed bolt in the corresponding connection perforation on described a plurality of rope sheaves unit, described bolt passes on the end of described connection perforation and is combined with nut.

Because the utilization of technique scheme, the utility model compared with prior art has following advantage: on the rope sheave that the rope sheave unit assembly of a plurality of arranged in co-axial alignment forms, if grooving wearing and tearing take place to break down, then a corresponding rope sheave unit is removed, changing new rope sheave unit gets final product, do not need rope sheave integral body is changed, save the use cost of rope sheave, and, on the lift car of different loads, the radical of steel rope is normally different, like this, when needs increase the radical of steel rope, correspondingly, the number of the grooving on the rope sheave also will correspondingly increase, for the whole rope sheave of mentioning in the background technology,, then need to use new whole rope sheave if increase the number of grooving, and in the utility model, as long as increase new rope sheave unit on the basis of rope sheave, therefore, rope sheave of the present utility model can increase or reduce the rope sheave unit as required, reach the increase of number of grooving or less, also can cost-cutting.

Description of drawings

Accompanying drawing 1 is looked scheme drawing for master of the present utility model;

Accompanying drawing 2 is a schematic side view of the present utility model, wherein not shown bolt or nut.

The specific embodiment

Further set forth structure of the present utility model below in conjunction with accompanying drawing.

Shown in Fig. 1-2, elevator rope sheave 3, but the rope sheave unit 2 that comprises a plurality of arranged in co-axial alignment, offer the grooving 6 that circumferentially extend on an edge on the outer peripheral face of each rope sheave unit 2, removably connect mutually between a plurality of rope sheaves unit 2, on the rope sheave 3 that is combined to form in the rope sheave unit 2 of a plurality of arranged in co-axial alignment, if 6 wearing and tearing of a grooving take place to break down, then a corresponding rope sheave unit 2 is removed, changing new rope sheave unit 2 gets final product, do not need rope sheave 3 integral body are changed, save the use cost of rope sheave 3, and, on the lift car of different loads, the radical of steel rope is normally different, like this, when needs increased the radical of steel rope, correspondingly, the number of the grooving 6 on the rope sheave 3 also will correspondingly increase, for the whole rope sheave of mentioning in the background technology, if increase the number of grooving, then need to use new whole rope sheave, and in the utility model, as long as on the basis of rope sheave 3, increase new rope sheave unit 2, therefore, rope sheave of the present utility model can increase or reduce rope sheave unit 2 as required, reaches the increase of number of grooving 6 or less.

In Fig. 1, on the rope sheave unit 2 of a plurality of arranged in co-axial alignment, adjacent two rope sheave unit 2 same axis are adjacent to, be fastened with the cooperation of nut 1 or dismounting mutually by bolt 4 between a plurality of rope sheaves unit 2, specifically, each rope sheave unit 2 offers a plurality of perforation 5 that are connected on the radial surface between centre hole 7 and the grooving 6, as shown in Figure 2, these a plurality of connection perforation 5 circumferential direction along rope sheave unit 2 are provided with separately, when between a plurality of rope sheaves unit, being connected, as shown in Figure 1, passed bolt 4 in the corresponding connection perforation 5 on a plurality of rope sheaves unit 2, bolt 4 passes on the end that connects perforation 5 and is combined with nut 1, and the fit system of bolt 4 and nut 1 makes that connection and the lock out operation between a plurality of rope sheaves unit 2 is simple.
