Description

Changing tracks and rail elevators for elevators Technical Field

[0001] This application relates to the field of rail elevator equipment technology, and in particular to a variable track for elevators and a rail elevator. Background Technology

[0002] Self-propelled rail elevators directly drive the elevator car up and down using drive wheels mounted on the elevator drive unit, eliminating the need for counterweights, traction, or traction cables. This results in a simple shaft layout, high shaft utilization, and an aesthetically pleasing design. Lifting speed and height are unrestricted. Utilizing tire friction drive wheels, the tires reduce vibration and noise, resulting in low wear, low noise, smooth and comfortable operation, and low maintenance costs. Rail elevators are integrated into buildings, with the elevator car moving up and down on a single vertical track.

Detailed Implementation

[0026] 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.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0028] This application provides a track changer for elevators, which guides the operation of elevator equipment. The track changer has multiple tracks and provides track changer functionality at bifurcations.

[0029] In this embodiment, the variable track includes a main track and a first branch track and a second branch track formed by the branching of the main track. The guide rail of the variable track includes at least one transverse guide rail wall and one longitudinal guide rail wall. The transverse guide rail wall and the longitudinal guide rail wall are used to guide the operation of the elevator equipment. The variable track can be a single-rail structure or a multi-rail structure. When the variable track is a single-rail structure, the main track, the first branch track, and the second branch track are each composed of one guide rail. When the variable track is a multi-rail structure, the main track, the first branch track, and the second branch track are each composed of multiple guide rails extending in the same direction. The multi-rail structure includes at least two guide rails. In one specific embodiment, the cross-section of the guide rail of the variable track is "I" shaped.

[0030] Furthermore, the track-changing track also includes a track-changing connection assembly, which includes a first lateral transition guide, a first longitudinal transition guide, a second lateral transition guide, and a second longitudinal transition guide, all of which are position-adjustable. Moreover, by adjusting the positions of the first lateral transition guide, the first longitudinal transition guide, the second lateral transition guide, and the second longitudinal transition guide, the guide rail of the main track can be engaged with the guide rail of the first branch track or the guide rail of the second branch track.

[0031] When the main track guide rail engages with the first branch track guide rail, the two ends of the first lateral transition guide body are aligned with the lateral guide rail walls of the main track and the first branch track guide rail, respectively. The two ends of the first longitudinal transition guide body are aligned with the longitudinal guide rail walls of the main track and the first branch track guide rail, respectively. The second lateral transition guide body and the second longitudinal transition guide body are both offset from the main track guide rail. At this time, the first lateral transition guide body and the first longitudinal transition guide body act as a transition structure between the main track and the first branch track, allowing the elevator to run between them. Furthermore, because the second lateral transition guide body and the second longitudinal transition guide body are offset from the main track guide rail, they do not interfere with the operation of the elevator.

[0032] When the guide rail of the main track engages with the guide rail of the second branch track, the two ends of the second lateral transition guide are aligned with the lateral guide rail walls of the main track and the second branch track, respectively, and the two ends of the second longitudinal transition guide are aligned with the longitudinal guide rail walls of the main track and the second branch track, respectively. The first lateral transition guide and the first longitudinal transition guide are both offset from the guide rail of the main track. At this time, the second lateral transition guide and the second longitudinal transition guide act as transition structures between the main track and the second branch track, allowing the elevator to run between them. Furthermore, because the first lateral transition guide and the first longitudinal transition guide are offset from the guide rail of the main track, they do not interfere with the operation of the elevator.

[0033] In this embodiment, the track-changing connection component is divided into a first lateral transition guide, a first longitudinal transition guide, a second lateral transition guide, and a second longitudinal transition guide, that is, the transition connection structure of the guide rail is divided into multiple parts, thereby facilitating the optimization of the space occupation of the track-changing connection component.

[0034] For ease of explanation, the following describes the track changer provided in the embodiment of this application with a specific structure.

[0035] Referring to Figures 1 and 2, the changing track includes a main track 100, and a first branch track 200 and a second branch track 300 formed by the branching of the main track 100. Referring to Figure 6, the guide rail 10 of the changing track includes at least one transverse guide rail wall 11 and one longitudinal guide rail wall 12; the transverse guide rail wall 11 and the longitudinal guide rail wall 12 are used to guide the operation of the elevator equipment. In the structures shown in Figures 1 and 2, the main track 100, the first branch track 200, and the second branch track 300 are each composed of two guide rails 10. In a specific embodiment, the cross-section of the guide rail of the changing track is I-shaped.

[0036] Referring again to Figures 3-5, the track changer also includes a track changer connection assembly, which includes a first lateral transition guide 21, a first longitudinal transition guide 22, a second lateral transition guide 23, and a second longitudinal transition guide 24, all of which are position-adjustable. Furthermore, by adjusting the positions of the first lateral transition guide 21, the first longitudinal transition guide 22, the second lateral transition guide 23, and the second longitudinal transition guide 24, the guide rail of the main track 100 can be engaged with the guide rail of the first branch track 200 or the guide rail of the second branch track 300. The elevator equipment on the changing track can enter the first branch track 200 or the second branch track 300 through the main track 100. When the changing track connecting component changes the track so that the guide rail of the main track 100 engages with the guide rail of the first branch track 200, the elevator equipment can run between the main track 100 and the first branch track 200 through the changing track connecting component. When the changing track connecting component changes the track so that the guide rail of the main track 100 engages with the guide rail of the second branch track 300, the elevator equipment can run between the main track 100 and the second branch track 300 through the changing track connecting component.

At this time, the first transverse transition guide 21 and the first longitudinal transition guide 22 act as a transition structure between the main track 100 and the first branch track 200, and the elevator equipment can run between the main track 100 and the first branch track 200 through the first transverse transition guide 21 and the first longitudinal transition guide 22. Furthermore, since the second transverse transition guide 23 and the second longitudinal transition guide 24 are both offset from the guide rail of the main track 100, the second transverse transition guide 23 and the second longitudinal transition guide 24 do not interfere with the operation of the elevator equipment.

[0038] Referring to Figures 2 and 5, when the guide rail of the main track 100 engages with the guide rail of the second branch track 300, the two ends of the second transverse transition guide 23 are aligned with the transverse guide rail walls 11 of the main track 100 and the second branch track 300, respectively, and the two ends of the second longitudinal transition guide 24 are aligned with the longitudinal guide rail walls 12 of the main track 100 and the second branch track 300, respectively. The first transverse transition guide 21 and the first longitudinal transition guide 22 are both offset from the guide rail of the main track 100. At this time, the second transverse transition guide 23 and the second longitudinal transition guide 24 act as transition structures between the main track 100 and the second branch track 300, and the elevator equipment can run between the main track 100 and the second branch track 300 through the second transverse transition guide 23 and the second longitudinal transition guide 24. Furthermore, since the first transverse transition guide 21 and the first longitudinal transition guide 22 are both offset from the guide rail of the main track 100, the first transverse transition guide 21 and the first longitudinal transition guide 22 do not interfere with the operation of the elevator equipment.
