Abstract
The invention discloses a steel strip for an elevator tractor. The steel strip comprises a steel strip body, wherein a plurality of steel wires are arranged in the steel strip body. The steel strip is characterized in that a plurality of grooves are formed on a side surface of the steel strip body along the length direction of the steel strip body; and a signal generating device is packaged in the steel strip body. The elevator hoistway wiring can be simplified, and the steel strip has a breakage warning function.
Description
Technical field
The present invention relates to a kind of elevator traction machine, relate in particular to a kind of elevator traction machine 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, although yet use steel band to solve the multiple deficiency of wire rope, but loaded down with trivial details defective and the problem of unresolved lift well wiring still, in addition, existing steel band function singleness does not have fracture and asks function for instructions.
Summary of the invention
Technical problem to be solved by this invention provides a kind ofly can simplify lift well wiring, have an elevator traction machine steel band of fracture alarm function simultaneously.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of elevator traction machine steel band, comprise the steel band body, have many steel wires in the described steel band body, offer a plurality of grooves along its length on the side surface of described steel band body, be packaged with signal occurrence device in the described steel band body.
Offer respectively three grooves along its length on the side surface of described steel band body.
The upper surface of described steel band body and lower surface are roughened surface.
Compared with prior art, beneficial effect of the present invention is:
Because elevator traction machine of the present invention offers a plurality of grooves along its length with steel band on the side surface of steel band body, just can be with signaling line during use, power line etc., the signaling line that particularly moves with steel band is distributed in the groove, so just can simplify the wiring in the hoistway, reduce the generation of fault, in addition, in the steel band body, be filled with signal occurrence device, when using, this signal occurrence device is electrically connected with signaling line, when rupturing, steel band must pull apart signaling line, at this moment signal occurrence device does not just receive closed signal, ask signal for instructions thereby can send, reminding user, so the present invention can simplify the lift well wiring, has simultaneously the fracture alarm function.
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: steel band body 2, steel wire 4, groove 6, signal occurrence device 8.
Embodiment
As shown in Figure 1, a kind of elevator traction machine steel band of the present invention, comprise steel band body 2, have many steel wires 4 in this steel band body 2, and also has coarse upper surface, two side surfaces of lower surface and connection upper surface and lower surface, offer three grooves 6 along its length respectively on these two side surfaces, just can be with signaling line during use, power line etc., the signaling line that particularly moves with steel band is distributed in the groove 6, so just can simplify the wiring in the hoistway, reduce the generation of fault, in addition, in steel band body 2, be filled with signal occurrence device 8, be electrically connected with signaling line when this signal occurrence device 8 uses, will inevitably pull apart signaling line when steel band ruptures, at this moment signal occurrence device 8 does not just receive closed signal, ask signal for instructions thereby can send, reminding user.
In sum.The present invention can simplify lift well and connect up, has simultaneously the fracture alarm function.
The above only is better embodiment 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.
