Description

Technical Field

[0001] The utility model relates to the technical field of elevators, and particularly relates to a high-precision elevator guide rail. Background Art

[0002] The elevator guide rail is an important part of the elevator operation, mainly having functions such as guiding and bearing loads. The guiding function ensures that the elevator car and the counterweight device run smoothly along a predetermined vertical path. During the operation of the elevator, the car and the counterweight need to move on the straight track defined by the guide rail. The guide rail is like the railway track of a train, guiding the running direction of the elevator, preventing the car and the counterweight from shaking, shifting or rotating, so as to ensure the smoothness and safety of the elevator operation. The load-bearing function is to bear the weights of the car and the counterweight as well as the dynamic loads during the elevator operation. The elevator will generate impact forces during the start, stop, acceleration and deceleration processes, and these forces need to be borne by the guide rail. At the same time, the guide rail also needs to bear the weight of the passengers or goods in the car and transfer these weights to the support structure of the elevator shaft.

[0003] For example, the Chinese patent with the publication number CN216863325U discloses an elevator guide rail. The elevator guide rail includes a convex portion for guiding the operation of the elevator car and mounting ears located on both sides of the convex portion, and mounting holes are provided on the mounting ears; a mounting portion is provided on the convex portion of the guide rail body; a protection portion is covered outside the convex portion and is mounted and positioned on the convex portion through the mounting portion. The installation of the protection portion is realized through the setting of the mounting portion, and the protection of the guide rail body is realized through the setting of the protection portion, avoiding the direct contact between the elevator guide rail and the elevator guide shoe, and increasing the service life of the elevator guide rail body.

[0004] Although the above example can protect the guide rail body through the protection portion to extend the service life of the elevator guide rail, in order to improve the smoothness during the elevator operation, it is necessary to apply lubricating oil to the surface of the guide rail to reduce the friction force during the elevator operation. The existing methods of adding lubricating oil mostly directly apply it into the lubrication points, and the guide rail cannot store lubricating oil. During the operation of the elevator, the friction force with the guide rail is large, resulting in too fast consumption speed of the lubricating oil, and thus it is necessary to frequently add lubricating oil to the elevator guide rail, which is somewhat inconvenient to use. Summary of the Utility Model

[0005] The utility model provides a high-precision elevator guide rail to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0007] A high-precision elevator guide rail, comprising a guide rail body, wherein mounting holes are formed on the surface of the guide rail body, lubricating grooves are formed on the surface of the guide rail body, engaging grooves are formed at the lower end of the guide rail body, and a protruding portion is provided at the upper end of the guide rail body.

[0008] A further improvement of the technical solution of the present utility model lies in that: a mounting plate is engaged with the back surface of the guide rail body, and an oil storage box is fixedly connected to one side of the mounting plate close to the guide rail body.

[0009] A further improvement of the technical solution of the present utility model lies in that: the surface of the oil storage box abuts against the inner wall of the guide rail body, and an oil filling port is provided at one end of the top of the oil storage box.

[0010] A further improvement of the technical solution of the present utility model lies in that: a capillary fiber bundle is arranged inside the oil storage box, and the upper end of the capillary fiber bundle is immersed in the lubricating oil inside the oil storage box.

[0011] A further improvement of the technical solution of the present utility model lies in that: the lower end of the capillary fiber bundle is fixedly connected with an oiling ring, and the surface of the oiling ring is engaged with the inside of the lubricating groove.

[0012] A further improvement of the technical solution of the present utility model lies in that: a protruding portion for the elevator to slide is provided in the middle of the guide rail body.

[0013] A further improvement of the technical solution of the present utility model lies in that: the length of the engaging groove is equal to the length of the protruding portion.

[0014] A further improvement of the technical solution of the present utility model lies in that: the inner diameter of the lubricating groove is slightly smaller than the diameter of the oiling ring.

[0015] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:

[0016] The present utility model provides a high-precision elevator guide rail. Through the setting of the oil storage box, a large amount of lubricating oil can be stored in the guide rail. During the operation of the elevator, under the action of the capillary phenomenon of the capillary fiber bundle immersed in the lubricating oil in the oil storage box, the lubricating oil in the oil storage box is slowly drained into the oiling ring. During the process when the elevator passes through the oiling ring, the lubricating oil is evenly applied, thereby realizing the oiling effect. Compared with the conventional technology, the large amount of lubricating oil stored in the oil storage box can be used for long-term lubrication without the need to frequently add lubricating oil, making it more convenient to use. At the same time, the friction between the elevator guide rail after applying the lubricating oil and the elevator is smaller and the precision is higher. BRIEF DESCRIPTION OF THE DRAWINGS
