Abstract

The utility model discloses a flat steel belt for a lift, which is applied to a lift dragging transmission system. The flat steel belt comprises a plastic body with a flat structure. A plurality of groups of steel wire ropes are embedded in the plastic body and each group of steel wire ropes at least consists of a left-laid steel wire rope and a right-laid steel wire rope. Each steel wire in the steel wire ropes is coated by a zinc-plated layer. The zinc-plated layer is further coated by an adhesive film layer. The adoption of the flat steel belt for the lift uses the plastic body in the flat structure, so that the diameter of a traction sheave can be reduced and the production cost of the lift is reduced. Meanwhile, the flat steel belt has the advantages of no noise, environmental friendless, high security and high reliability in work, so that the corresponding working amount of the lift maintenance is saved, and the maintenance cost of the lift is reduced.

Description

The elevator flat Flat Strip Steel

Technical field

The utility model relates to a kind of express elevator traction transmitting assemblies, especially relates to a kind of flat steel band that is used for the elevator hoisting transmission.

Background technique

At present, along with tall building is more and more, the express elevator demand increases, and the elevator hoisting that the most of elevator system maker of China offers market goes up and down all to adopt elevator to use wire rope, and in use there is following defective in this product:

1) elevator noise in use is bigger;

2) grease can spill in the wire rope, pollutes machine room;

3) wire rope can produce disconnected strand of fracture of wire after using a period of time, makes elevator shake and shutdown, causes the increase of elevator maintenance cost.

The model utility content

To the problems referred to above, the purpose of the utility model is to provide a kind of elevator flat Flat Strip Steel, and it has the characteristics of simple in structure, environmental protection, noise free and reliable installation, to solve the problem that existing elevator exists with wire rope.

The purpose of the utility model is to realize through following technological scheme:

A kind of elevator flat Flat Strip Steel; It comprises the plastic body of flat structure; Be embedded with many group wire rope in the said plastic body; Every group of wire rope is made up of left-hand lay and two wire rope of right-laid at least, and every steel wire in the said wire rope all is coated with zinc coat outward, and said zinc coat also is coated with outward and coheres rete.

Especially, said plastic body is a polyurethane.

Especially, evenly be embedded with 8～12 groups of wire rope in the said plastic body.

Especially, said wire rope is formed by 7 strands, per sharely is made up of 7 steel wires.。

The beneficial effect of the utility model does; Said elevator flat Flat Strip Steel adopts the plastic body of flat structure, can reduce the traction sheave diameter, reduces the elevator cost of production; Simultaneously when work; Elevator maintain and protection relevant work amount is saved in noise free, environmental protection, safe and reliable, has reduced the maintenance cost of elevator.

Description of drawings

According to accompanying drawing and embodiment the utility model is done further explain below.

Fig. 1 is the partial section of the utility model elevator flat Flat Strip Steel;

Fig. 2 is the sectional view of the wire rope of the utility model elevator flat Flat Strip Steel;

Fig. 3 is the sectional view of the individual wire of the utility model elevator flat Flat Strip Steel.

Among the figure:

1, plastic body; 2, left-hand lay wire rope; 3, right-hand lay wire rope; 4, steel wire; 5, zinc coat; 6, cohere rete.

Embodiment

Please referring to figs. 1 through shown in Figure 3, Fig. 1 is the partial section of the utility model elevator flat Flat Strip Steel; Fig. 2 is the sectional view of the wire rope of the utility model elevator flat Flat Strip Steel; Fig. 3 is the sectional view of the individual wire of the utility model elevator flat Flat Strip Steel.

In the present embodiment, a kind of elevator flat Flat Strip Steel comprises the plastic body 1 of flat structure, is processed by polyurethane in plastic body described in the present embodiment 1; Be embedded with 12 groups of wire rope in the said plastic body 1, every group of wire rope is made up of left-hand

lay wire rope

2 and 3 two of right-hand lay wire ropes, and said left-hand lay wire rope 2 and right-hand lay wire rope 3 are by 7 strands of compositions; Per sharely be made up of 7 steel wires, the tensile strength grade is the extra-high-speed level, and the rope minimum breaking force is the extra-high-speed level; There is not oil production, elongation at break≤0.2%.

The every steel wire 4 outer zinc coats 5 that all are coated with in said left-hand lay wire rope 2 and the right-hand lay wire rope 3, said zinc coat 5 outer also being coated with are cohered rete 6, and the said rete 6 that coheres makes whole wire rope ability and urethane plastic body 1 effective strong bonded.

Above-mentioned elevator flat Flat Strip Steel adopts the plastic body of flat structure, can reduce the traction sheave diameter, reduces the elevator cost of production, and when work, elevator maintain and protection relevant work amount is saved in noise free, environmental protection, safe and reliable, has reduced the maintenance cost of elevator simultaneously.
