Description

Elevator door hanging wheel

The present invention claims the priority of a Chinese patent application filed on January 20, 2016, to the Chinese State Intellectual Property Office, having the application number 201610038860.3 and entitled "Elevator Door Hanging Wheel".

Technical field

The present disclosure relates generally to elevator accessories, and more particularly to an elevator door hanger.

Background technique

At present, with the increase of high-rise buildings, the use of elevators is more and more extensive, so the requirements for the hanging wheels on the hanging plate of the elevator door system are also getting higher and higher. The structure of these hanging wheels is basically by the wheel center and the wheel. The shell is formed by providing a rolling groove on the circumference of the wheel housing. The groove shape of the existing rolling groove is substantially circular arc shape, and the door hanging wheel and the guide rail are matched. When the door system is subjected to a slight external force, the door hanging wheel cannot be kept vertical, which easily causes interference between various components inside the elevator, causing friction and abnormal noise.

Summary of the invention

In view of the above-mentioned drawbacks or deficiencies in the prior art, it is desirable to provide a stable elevator door hanger.

The elevator door hanging wheel of the present invention comprises a groove type, and the groove type is used for multi-point contact cooperation with the guide rail. The groove type is provided with a first side surface, a second side surface and a bottom surface, and the first side surface and the second side surface are located on both sides of the bottom surface.

The utility model has the advantages that the groove type is adopted, so that the elevator door hanging wheel and the guide rail cooperate with each other for multi-point contact, thereby avoiding the inclination of the elevator door hanging wheel due to the external force, avoiding the dryness between the components and the friction, and reducing the friction. The noise of the elevator running.

detailed description

The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention, rather than the invention. It should also be noted that, for the convenience of description, only parts related to the invention are shown in the drawings.

It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings.

Referring to FIG. 1 , an elevator door hanging wheel includes a slot type 1 for a multi-point contact fit with a guide rail. The slot type 1 is provided with a first side surface 11 , a second side surface 12 and a bottom surface 13 , and the first side surface The 11 and second side faces 12 are located on either side of the bottom surface 13.

In an embodiment of the present invention, an elevator door hanging wheel includes a groove type 1, and the groove type 1 is used for multi-point contact with the guide rail, and the elevator door hanging wheel and the guide rail are rolled and matched, and when the elevator door hanging wheel is rolled on the guide rail At the time, due to the multi-point contact coordination, the stability of the cooperation is increased, the elevator operation is more stable, and the abnormal noise generated by the friction between the components is reduced.

In the embodiment of the present invention, the groove type 1 is provided with a first side surface 11, a second side surface 12 and a bottom surface 13, and the first side surface 11 and the second side surface 12 are located on both sides of the bottom surface 13, and the elevator door hanging wheel cooperates with the guide rail. During the process, the first side surface 11, the second side surface 12, and the bottom surface 13 are respectively in point contact with the guide rails, and the first side surface 11 and the second side surface 12 are distributed on both sides of the bottom surface 13 to form a three-point contact fit, which is relatively stable when the elevator is subjected to the elevator. When the external force is applied, the elevator door hanging wheel does not tilt.

Further, the bottom surface 13 is provided with a protrusion for rolling engagement with the guide rail.

In the embodiment of the present invention, the bottom surface 13 is provided with a protrusion for the rolling cooperation with the guide rail. When the elevator runs for a period of time, the friction of the elevator door hanging wheel and the guide rail may cause slight Wear, the protrusion provided on the bottom surface 13 ensures the bottom surface 13 and the guide rail In time, it is a point of contact.

Referring to Fig. 2, the convex section has an arc shape.

In the embodiment of the present invention, the cross section of the protrusion is an arc shape. When the protrusion is worn, the line is matched between the protrusion and the guide rail to reduce the resistance during the operation of the elevator door hanging wheel.

Further, the contact point when the protrusion is matched with the guide rail is located on the center line of the outer arc surface of the guide rail.

In the embodiment of the present invention, the contact point when the protrusion cooperates with the guide rail is located on the center line of the outer arc surface of the guide rail. In the normal working work of the elevator, mainly the convex force on the elevator door hanging wheel is forced, so that the elevator The door hanging wheel can ensure reasonable loss and increase the service life of the elevator door hanging wheel.

Referring to Figure 3, the first side 11 is for point contact with the rail and the second side 12 is for point contact with the rail.

Further, the first contact point of the bottom surface 13 and the guide rail, the first side surface 11 and the second contact point of the guide rail, and the second side surface 12 are located on the same circle as the third contact point of the guide rail.

In the embodiment of the present invention, the first contact point of the bottom surface 13 and the guide rail, the second contact point of the first side surface 11 and the guide rail, and the second contact point of the second side surface 12 and the guide rail are located on the same circle, such a structure The elevator door hanger wheel runs more smoothly on the guide rails.

Further, the groove type 1 is a polyurethane groove type.

In the embodiment of the present invention, the groove type 1 is a polyurethane groove type, which has good wear resistance and high mechanical strength.

The above description is only a preferred embodiment of the present application and a description of the principles of the applied technology.
