Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of elevator equipment, in particular to a self-driving elevator track and a self-driving elevator. BACKGROUND

[0002] Traditional elevators use the traction principle of steel wire rope plus counterweight, which has a complex structure, resulting in low hoistway utilization rate and increased installation and maintenance workload. The track elevator based on self-driving technology can effectively solve the above problems. The principle is to install a driving system on the car, which includes a driving wheel. The driving wheel is pressed against the track surface by applying pressure to it. The rotation of the driving wheel can drive the car to move up and down along the track surface. This driving method not only simplifies the structure and greatly improves the hoistway space utilization rate, but also has the advantages of safe and smooth operation, no meshing impact and restlessness, high speed, etc.

[0003] The gravity and load of the car are balanced by the friction between the driving wheel and the track surface, and the size of the friction is determined by the relative pressure and friction coefficient between the driving wheel and the track surface. When the tire is pressed against the track surface, the tire will deform locally and come into contact with the track surface. When the roller rolls, the tire and the track surface contact area will produce a gas explosion noise similar to the suction cup effect. At the same time, as shown in the figure, when the tire rolls, theoretically, except for the 0 point and the track surface, the linear speed of the other contact areas such as P and Q points is different from that of the O point. Therefore, there is relative movement between the tire and the track surface, which produces local scraping sound. The noise generated will greatly reduce the passenger's ride experience.

[0034] The following is a specific embodiment of the present application and further describes the technical solutions of the present application in combination with the drawings, but the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided only to help a comprehensive understanding of the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope of protection of the present application. In addition, in order to be clear and concise, the description of known functions and structures is omitted.

[0035] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0036] The embodiment of the present application provides a self-driven elevator track for reducing noise of tire driving of the self-driven elevator during operation. Figure 1 The track for the self-driven elevator is provided with a track surface for driving wheel driving, and at least one A type guide rail surface exists in the track surface for driving wheel driving; the A type guide rail surface is provided with a noise reduction area, and the A type guide rail surface is a concave-convex non-flat surface in the noise reduction area.

[0037] Specifically, the A type guide rail surface is provided with the noise reduction area, and the A type guide rail surface is a concave-convex non-flat surface in the noise reduction area, so that the continuous contact and scraping time of the same position of the material on the driving wheel with the track surface can be reduced when the driving wheel drives in the noise reduction area, the suction cup cavity causing air explosion is relieved, and finally the effect of optimizing and solving noise is achieved.

[0038] Further, the noise reduction area is formed into a concave-convex non-flat surface by arranging the recessed structure, and the area ratio of the recessed structure to the noise reduction area is 15%-55%. It should be understood that in the contact area of the driving wheel and the track surface, the unloading areas formed by the recessed structure are uniformly arranged and have a certain density. If the area ratio of the recessed structure is too small, the noise optimization effect is not good; if the area ratio of the recessed structure is too large, the actual contact area of the driving wheel and the track surface is reduced, the tangential stress of the local material on the driving wheel is increased, and the service life of the driving wheel is reduced. Therefore, through long-term research and actual test, the area ratio of the recessed structure to the noise reduction area is set to be greater than 15% to ensure the noise optimization effect of the driving wheel, and the area ratio of the recessed structure to the noise reduction area is set to be less than 55% to ensure that the driving wheel has sufficient service life. Therefore, the area ratio of the recessed structure to the noise reduction area is set to be 15%-55%, so that the noise level and the service life level of the driving wheel can be balanced.

[0039] When the noise reduction area is formed into a concave-convex non-flat surface by arranging the recessed structure, and the recess depth h of the recessed structure is not less than 0.5 mm, that is, h>=0.5 mm.
