Abstract
The invention discloses an elevator rope pulley. The rope pulley comprises a plurality of coaxially arranged rope pulley units, wherein a rope groove extending along the circumference is formed on the outer circumference of each rope pulley unit; and a plurality of rope pulley units are detachably connected. On the rope pulley which is formed by combination of a plurality of coaxially arranged rope pulley units, if one rope groove is abraded and broken, the corresponding rope pulley unit is removed, and a new rope pulley unit replaces without changing the whole rope pulley, so the use cost of the rope pulley is saved; the numbers of the steel wire ropes are not the same on elevator cars with different loads, therefore, while the number of the steel wire ropes is required increasing, the number of rope grooves on the rope pulley is increased correspondingly. Regarding the integral rope pulley in the background technology, if the number of the rope grooves is required to be increased, a new integral rope pulley is necessary to use, but in the invention, new rope pulley units are only increased on the basis of the rope pulley, so the rope pulley ensures that the rope pulley units can be increased or reduced according to requirement to achieve increase or reduction of the number of the rope grooves, and the cost can be reduced.
Description
Technical field
The present invention 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 invention is to provide the elevator rope sheave that a plurality of rope sheaves unit arranged in co-axial alignment forms, wherein each rope sheave unit has a grooving.
For achieving the above object, the technical solution used in the present invention 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 present invention 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 present invention, as long as increase new rope sheave unit on the basis of rope sheave, therefore, rope sheave of the present invention 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 invention;
Accompanying drawing 2 is a schematic side view of the present invention, wherein not shown bolt or nut.
The specific embodiment
Further set forth structure of the present invention 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 present invention, as long as on the basis of rope sheave 3, increase new rope sheave unit 2, therefore, rope sheave of the present invention 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.
