Description
Technical Field
The utility model belongs to the technical field of the elevator technique and specifically relates to a steel band deviation prevention device for elevator is related to.
Background
The main function of the traction system of an elevator is to output and transmit power to operate the elevator. The traction system mainly comprises a traction machine, a traction wire, a guide wheel and a diversion sheave, wherein the traction wire comprises a steel wire rope and a steel belt. Compared with the traditional steel wire rope, the steel belt has longer service life which is 2-3 times that of the steel wire rope; lighter in weight, about 20% lighter than conventional steel wire rope; the elevator is more firm and durable, the safety is stronger, each composite steel belt can bear 3200 kilograms of pulling force/6400 kilograms of pulling force, and each elevator is 3 composite steel belts at least.
However, the steel band can take place to squint in the use, and its offset is within 1 centimetre, but, current guide pulley can not be at the axial displacement of connecting axle for the steel band can with the marginal butt of guide pulley, thereby the steel band in the motion can rub with the marginal of guide pulley, can produce the noise on the one hand, influences passenger's the experience of taking advantage of the ladder, and on the other hand goes back to damage the steel band, causes the influence to the safe operation of elevator.
Therefore, there is a need to provide a new technical solution to overcome the above-mentioned drawbacks.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a can effectively solve above-mentioned technical problem's steel band deviation preventing device for elevator.
In order to achieve the purpose of the utility model, the following technical proposal is adopted:
a steel strip deviation preventing device for an elevator comprises:
a connecting shaft;
guide wheels: the steel belt is rotationally connected with the connecting shaft and moves in the axial direction of the connecting shaft, and the steel belt is in contact with the guide wheel.
Further: and the limiting part is fixedly arranged on the connecting shaft and limits the moving range of the guide wheel.
Further: the guide wheel has a movement range of at most 15 mm.
Further: the limiting piece is a shaft clamp spring.
Further: the guide wheel is connected with the connecting shaft through a bearing.
Further: the guide wheel is internally provided with a step-shaped cavity, one side of the bearing is abutted to the guide wheel, the other side of the bearing is provided with a fixing piece, the fixing piece is fixedly connected with the guide wheel, and the bearing is abutted to the fixing piece.
Further: the fixing piece is a hole clamp spring.
Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses steel band deviation prevention device for elevator, steel band take place to squint, and it can the guide pulley is in the axial displacement of connecting axle avoids the edge of steel band and guide pulley to take place the friction to reduce the noise on the one hand, on the other hand guarantees the life of steel band.
Drawings
Fig. 1 is the structure schematic diagram of the steel belt deviation preventing device for the elevator of the utility model.
In the figure: the device comprises a connecting shaft 1, a guide wheel 2, a bearing 3, a fixing piece 4 and a limiting piece 5.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, a clear and complete description will be given below with reference to the technical solutions of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention.
