Description

A kind of hoisting rope for elevator

Technical field

The utility model is related to a kind of hoisting rope for elevator, belongs to elevator accessory technical field.

Background technology

The car rope traction of elevator, is to meet the safety requirements that elevator runs up and down, the pass of rope sheave and steel wire rope System is difficult to be adapted to the direction of rope sheave miniaturization, therefore, current people gradually replace steel wire rope, drawing belt using drawing belt Main clad by outer layer and be wrapped by layer be coated in steel wire rope constitute, and existing drawing belt is primarily present following asking Topic：Single cabin elevator and double-car elevator cannot be simultaneously applied to, the contact friction force between drawing belt and traction sheave is not enough, leads Draw effect undesirable, the problems such as steel wire rope is easily escaped from clad.

Utility model content

Based on above-mentioned deficiency, the utility model provides a kind of while being applied to single, double cabin elevator and and traction Drawing belt with preferable traction effect between wheel.

To achieve these goals, the technical scheme that the utility model is adopted for：

A kind of hoisting rope for elevator, including some spaced steel wire ropes and by the polyurethane rubber including covering of rope Glue clad, the outer surface bi-directional symmetrical of clad is provided with some cladding range upon range of mountains being spaced apart, shape between adjacent cladding layers peak Into clad paddy, the cross section for coating range upon range of mountains and clad paddy is triangular in shape.

The steel wire rope adopts galvanized steel wire rope.

The steel wire rope is compiled sth. made by twisting and is formed using six strands of steel wires, per share to be made up of seven steel wires volume sth. made by twisting, uses the straight of steel wire Footpath is 2.15 millimeters.

Clad of the present utility model adopts polyurethane rubber, with hardness it is high, intensity is good, elastic good and wear-resisting excellent Point, easy to wear when clad is contacted with traction sheave and with larger elasticity, steel wire rope is not easy to be escaped from clad；Cladding Layer using two-way interval concaveconvex shape design so that drawing belt of the present utility model can simultaneously be applied to single cabin elevator and double Cabin elevator, with wider array of applicability；The concavo-convex cross-section of drawing belt adopts triangular design so as to have with the conduit of traction sheave Having preferably coordinate and contact so as to which frictional force increases, and reaches more preferable traction effect.

The utility model is further elaborated below by way of the drawings and specific embodiments.

Description of the drawings：

Fig. 1 is the cross-sectional structure schematic diagram of the utility model drawing belt.

Specific embodiment：

With reference to shown in Fig. 1, a kind of hoisting rope for elevator that the utility model is provided, including the steel wire that some intervals are arranged side by side Rope 1 and steel wire rope 1 is coated on into interior clad 2, clad 2 is packed in the interval gap of adjacent steel wire rope, and is adopted Use polyurethane rubber material, make whole drawing belt that there is the characteristics of intensity is high, hardness is good, wear-resisting and elastic good, clad 2 with drag Not easy to wear during running wheel contact friction, high resiliency it also avoid the steel wire rope 1 of inside and escape from clad 2.In order to increase Plus the contact area of the type groove of clad 2 and traction sheave, and then increasing traction effect, by the outer surface of clad be designed as by The clad paddy composition of some cladding range upon range of mountains being spaced apart and connection adjacent cladding layers peak, and coat range upon range of mountains and clad paddy Cross section is triangular in shape, makes thicker with the type groove contact position clad 2 of traction sheave, and protected effect is more preferable.Further for same When, adopts two-way suitable for single cabin elevator and double-car elevator, the cladding range upon range of mountains and clad paddy on the outer surface of clad 2 It is symmetrical arranged.

Each independent steel wire rope 1 in above-mentioned drawing belt is to compile sth. made by twisting by six strand steel wire ropes to form, each strand steel wire rope It is to compile sth. made by twisting by a diameter of 2.15 millimeters of seven zinc-coated wires to form, galvanized steel wire rope has the advantages that corrosion-resistant and intensity is high, Increased the service life of drawing belt.Individual wire in said structure its rupture strength is more than 3700N, using aforesaid way shape Into drawing belt its total rupture strength be more than 37000N, tractive force is big, and traction effect is good.

Above example only to illustrate the technical solution of the utility model and unrestricted, those of ordinary skill in the art couple Other modifications or equivalent that the technical solution of the utility model is made, without departing from technical solutions of the utility model Spirit and scope, all should cover in right of the present utility model.
