Detailed Implementation

[0041] The following are specific embodiments of this application, described in conjunction with the accompanying drawings, to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments. In the following description, specific details such as particular configurations and components are provided merely to aid in a comprehensive understanding of the embodiments of this application. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0043] This application provides a track-changing track for a rail elevator. The track-changing track includes a main track and a first branch track and a second branch track formed by the branching of the main track. A track-changing connection assembly is provided at the transition position between the main track and the first and second branch tracks. The main track is composed of a first guide rail and a second guide rail; the first branch track is composed of a third guide rail and a fourth guide rail; the second branch track is composed of a fifth guide rail and a sixth guide rail; wherein the fourth and fifth guide rails are located between the third and sixth guide rails; the third guide rail is located on one side of the first guide rail, and the sixth guide rail is located on one side of the second guide rail.

[0044] Furthermore, the track-changing connection assembly includes a first transition rail, a second transition rail, and an adjustable guide structure. The first transition rail is used to connect the first rail and the third rail, the second transition rail is used to connect the second rail and the sixth rail, and the adjustable guide structure is located between the first transition rail and the second transition rail.

[0045] Furthermore, the position of the adjustable guide structure is adjustable and can be laterally adjusted to a first position state and a second position state; when the adjustable guide structure is in the first position state, the adjustable guide structure constitutes a transition guide structure between the second guide rail and the fourth guide rail, so that the main track engages with the first branch track; when the adjustable guide structure is in the second position state, the adjustable guide structure constitutes a transition guide structure between the first guide rail and the fifth guide rail, so that the main track engages with the second branch track.

[0046] In this embodiment, the main track, the first branch track, and the second branch track are each composed of two guide rails. The elevator uses drive wheels to drive the car to run on the two guide rails. The track-changing connection assembly is located between the main track and the branch track, allowing the elevator car and drive unit to enter the first branch track or the second branch track from the main track via the track-changing connection assembly. It should be understood that the two guide rails constituting the track can be designed as two parts of a single integral structure, or as two independent parts.

[0047] Specifically, the track-changing connection assembly includes a first transition guide rail, a second transition guide rail, and an adjustable guide structure. The first transition guide rail connects between the first and third guide rails, the second transition guide rail connects between the second and sixth guide rails, and the adjustable guide structure is located between the first and second transition guide rails. The adjustable guide structure can be adjusted to engage the main track with either the first or second branch track. When the adjustable guide structure is adjusted to the first position, it forms a transition guide structure between the second and fourth guide rails, and simultaneously, the first transition guide rail forms a transition guide structure between the first and third guide rails. Therefore, through the connection of the adjustable guide structure and the first transition guide rail, the main track engages with the first branch track, allowing the elevator car and drive unit to run between the main track and the first branch track via the track-changing connection assembly. When the adjustable guide structure is adjusted to the second position, the adjustable guide structure forms a transition guide structure between the first guide rail and the fifth guide rail. At the same time, the second transition guide rail forms a transition guide structure between the second guide rail and the sixth guide rail. Therefore, through the connection of the adjustable guide structure and the second transition guide rail, the main rail and the second branch rail are joined together, and the elevator car and drive unit can run between the main rail and the second branch rail through the rail changing connection assembly.

[0048] Specifically, the adjustable guide structure switches between a first position state and a second position state by lateral movement, and the track-changing connection component can achieve position switching by setting a corresponding drive source to drive the adjustable guide structure to adjust lateral movement.

[0049] In this embodiment, for any guide rail of the variable track, it includes at least a transverse guide rail wall and a longitudinal guide rail wall; the transverse guide rail wall has a first guide rail surface and a second guide rail surface facing away from each other, the longitudinal guide rail wall is located on one side of the first guide rail surface of the transverse guide rail wall, and the longitudinal guide rail wall has a third guide rail surface facing the inside of the track; the second guide rail surface, the third guide rail surface, and the first guide rail surface located on one side of the third guide rail surface are the working surfaces for guiding the elevator operation. The adjustable guide structure includes a first transition guide body and a second transition guide body; the first transition guide body is used to form a transition guide structure for the transverse guide rail wall of the joined guide rail; the second transition guide body is used to form a transition guide structure for the longitudinal guide rail wall of the joined guide rail. Furthermore, when the adjustable guide structure is in the first position, the first transition guide body is aligned with the transverse guide wall of the second and fourth guide rails on the side closer to the first transition guide rail, and the second transition guide body is aligned with the longitudinal guide wall of the second and fourth guide rails; when the adjustable guide structure is in the second position, the first transition guide body is aligned with the transverse guide wall of the first and fifth guide rails on the side closer to the second transition guide rail, and the second transition guide body is aligned with the longitudinal guide wall of the first and fifth guide rails.

[0050] Specifically, for any section of the guide rail of the variable track, it has at least a transverse guide rail wall and a longitudinal guide rail wall, and other structures can also be included on this basis. The working surface on the guide rail is used to guide the movement of the elevator car and the driving device, and the rollers on the elevator car and / or the driving device can roll on the working surface. Each track consists of two guide rails. Referring to FIG. 7, the longitudinal guide rail wall is provided on the first guide rail surface 13 of the transverse guide rail wall. The first guide rail surface 13 is divided by the longitudinal guide rail wall 12, and the first guide rail surface 13 on one side of the third guide rail surface 15 is used as the working surface for guiding the operation of the elevator. Further, the working surface includes the second guide rail surface 14, the third guide rail surface 15 on the guide rail 10, and the first guide rail surface 13 on one side of the third guide rail surface 15 as the working surface for guiding the operation of the elevator. Therefore, the working surface on the guide rail is mainly provided inside the track near the two guide rails.
