Abstract
The invention discloses an assembled steel band for elevator tractors. The assembled steel band is characterized in that the assembled steel band for the elevator tractors comprises a surface layer, a middle layer and a bottom layer. A plurality of steel wires are arranged in the middle layer; side edges of the surface layer and the bottom layer respectively extend along the side surface of the middle layer to respectively form a surface layer extension portion and a bottom layer extension portion; and the surface layer extension portion is detectably connected with the bottom layer extension portion. The assembled steel band for the elevator tractors is easy to maintain and low in use cost.
Description
Technical field
The present invention relates to a kind of elevator traction machine, relate in particular to a kind of elevator traction machine assembly type steel band.
Background technique
At present, along with tall building is more and more, demand to express elevator also increases gradually, steel wire rope for elevator is all adopted in the elevator hoisting lifting that the most of elevator system maker of China offers market, after long-term the use, find, this product in use still has multiple deficiency, and is specific as follows:
1) because wire rope in use easily swings, cause elevator noise when operation larger;
2) for reducing the wearing and tearing of wire rope, usually scribble lubricant grease at wire rope, in use amplitude of fluctuation is larger owing to wire rope, causes the lubricant grease in the wire rope to spill, and 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.
Because the existence of above-mentioned deficiency, increasing elevator hoisting lifting begins to adopt steel band to replace the effect of wire rope, yet because existing steel band is an overall structure, so when any one wearing and tearing or when slight crack occurring, just can cause whole steel band to use.
Summary of the invention
Technical problem to be solved by this invention provides a kind of easy-maintaining, elevator traction machine assembly type steel band that user cost is low.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of elevator traction machine assembly type steel band, comprise top layer, mesosphere and bottom, be provided with many steel wires in the described mesosphere, the dual-side of described top layer and described bottom forms respectively top layer extension part and bottom extension part along the side surface extension in described mesosphere respectively, and described top layer extension part and described bottom extension part removably connect.
Be provided with lug boss on the described bottom extension part with on the contacted end face of described top layer extension part, be provided with the groove corresponding with described lug boss on the extension part of described top layer.
Compared with prior art, beneficial effect of the present invention is:
Because elevator traction machine of the present invention adopts the top layer and the bottom that removably connect to coat the mesosphere with steel wire with the assembly type steel band, so behind the wearing and tearing of top layer or bottom or cracking, only need change the top layer or bottom gets final product, need not integral replacing, maintenance is easier to, so also saved user cost, so easy-maintaining of the present invention, user cost are low.
Description of drawings
Describe the present invention in detail below in conjunction with drawings and embodiments:
Fig. 1 is structural representation of the present invention.
Among the figure: top layer 2, top layer extension part 21, mesosphere 4, bottom 6, bottom extension part 61, steel wire 8, lug boss 10.
Embodiment
As shown in Figure 1, a kind of elevator traction machine assembly type steel band of the present invention, include top layer 2, mesosphere 4 and bottom 6, be provided with many steel wires 8 in its mesosphere 6, the extension of 6 side surface forms respectively top layer extension part 21 and bottom extension part 61 to the dual-side of top layer 2 and bottom 6 along the mesosphere respectively, this top layer extension part 21 and bottom extension part 61 removably connect, concrete Placement is: be provided with lug boss 10 on the bottom extension part 61 with on the top layer extension part 21 contacted end faces, be provided with the groove (not shown) corresponding with lug boss 10 on the top layer extension part 21, namely realized removably connecting with engaging of groove by lug boss 10, get final product so behind 6 wearing and tearing of top layer 2 or bottom or cracking, only need top layer 2 or bottom 6 changed, thereby need not integral replacing, not only maintenance is easier to, and has so also saved user cost.
In sum.Easy-maintaining of the present invention, user cost are low.
The above only is preferred embodiments of the present invention; protection scope of the present invention is not limited with above-mentioned mode of execution; as long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection domain of putting down in writing in claims.
