Description

Technical Field

[0001] This application relates to the field of elevator equipment technology, and in particular to an embedded rail-type elevator device. Background Technology

[0002] Self-propelled rail elevators utilize drive wheels mounted on the elevator car to directly propel the car up and down, eliminating the need for counterweights, traction, or traction cables. This results in a simpler and more aesthetically pleasing shaft layout. Lifting speed and height are unrestricted. The use of tire friction drive wheels reduces vibration and noise, minimizing wear and ensuring smooth, comfortable operation with low maintenance costs. However, integrating rail elevators into buildings requires consideration of cost, shaft space, reliability, and complexity when implementing track changing mechanisms. Currently, there is still room for optimization in terms of structural stability and complexity for some double-track elevators. Utility Model Content

Detailed Implementation

[0025] 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.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0027] refer to Figure 1 The embedded rail-mounted elevator equipment includes: a car 10, a drive unit 20, and two guide rails 30; a connection is provided between the car 10 and the drive unit 20. Figure 1 In the structure shown, both the car 10 and the drive unit 20 move along the two guide rails 30. Specifically, the car 10 is connected to the two guide rails 30 via a plurality of first limiting rollers 23, and the drive unit 20 is connected to the two guide rails 30 via a drive wheel 22 and a plurality of first limiting rollers 23.

[0028] Two guide rails 30 are laterally spaced, and for any guide rail, the guide rail includes a first transverse guide rail wall 31 and a longitudinal guide rail wall 32, with the longitudinal guide rail wall 32 disposed on the first side of the first transverse guide rail wall 31. Figures 1-3In the structure shown, the longitudinal guide rail wall 32 and the first transverse guide rail wall 31 are joined together perpendicularly. It should be understood that the two guide rails can be designed as two parts of a single integral structure, or as two independent parts. In one embodiment of this application, as... Figure 1 As shown, the two guide rails 30 are set independently of each other. In one embodiment of this application, the two guide rails are two parts of an integral structure.

[0029] refer to Figure 3 The drive unit 20 includes a mounting bracket 21, a drive wheel 22 mounted on the mounting bracket 21, a plurality of first limiting rollers 23, and a drive source 25. The drive source 25 can drive the drive wheel 22 to rotate so as to travel on the guide rail. (See also...) Figures 1-2 Multiple first limiting rollers 23 are arranged in multiple directions to press the two guide rails from multiple directions; for any guide rail, and the first limiting roller 23 and drive wheel 22 that cooperate with it, the first limiting roller 23 is located on the first side of the first transverse guide rail wall 31 and between the longitudinal guide rail walls 32 of the two guide rails, and the drive wheel 22 is located on the second side of the first transverse guide rail wall 31.

[0030] refer to Figure 2 For any guide rail, the first transverse guide rail wall 31 has a first side and a second side, the longitudinal guide rail wall 32 is located on the first side of the first transverse guide rail wall 31, the first limiting roller 23 is located on the first side of the first transverse guide rail wall 31, and the drive wheel 22 is located on the second side of the first transverse guide rail wall 31. All the first limiting rollers 23 of the drive device 20 are arranged between the longitudinal guide rail walls 32 of the two guide rails; in other words, the first limiting rollers 23 are arranged between the two guide rails and engage with the guide rail surface from the inner side between the two guide rails. It should be understood that in Figure 2 In the structure shown, multiple first limiting rollers 23 are arranged in multiple directions to press the two guide rails from multiple directions.

[0031] In one embodiment of this application, the guide rail 30 further includes a second transverse guide rail wall 33, which is positioned opposite to the first transverse guide rail wall 31, and a longitudinal guide rail wall 32 connects the first transverse guide rail wall 31 and the second transverse guide rail wall 33. In one embodiment, the guide rail cross-sectional shape formed by the first transverse guide rail wall 31, the second transverse guide rail wall 33, and the longitudinal guide rail wall 32 is H-shaped or h-shaped. Figure 2As shown, for any guide rail and its cooperating first limiting roller 23, the first limiting roller 23 is arranged between the first transverse guide rail wall 31 and the second transverse guide rail wall 33, and is located between the longitudinal guide rail wall 32 of the two guide rails. Multiple first limiting rollers 23 respectively press against the first transverse guide rail wall 31, the second transverse guide rail wall 33, and the longitudinal guide rail wall 32. Furthermore, the drive source 25 and the drive wheel 22 are located on the second side of the first transverse guide rail wall 31. The drive wheel 22 and the first limiting roller 23 together constrain the drive device 20 onto the two guide rails. As the drive source 25 outputs power, the drive wheel 22 rotates and moves on the guide rail.

[0032] refer to Figures 3-5 The car 10 includes a car body 11 and a guide frame 12. The guide frame 12 is fixed to the back of the car body 11. A plurality of second limiting rollers 123 are provided on the guide frame 12. The plurality of second limiting rollers 123 are arranged in multiple directions to press the two guide rails from multiple directions. The car body 11 is located on the second side of the first transverse guide rail wall 31. The guide frame 12 is located between the longitudinal guide rail walls 32 of the two guide rails. For any guide rail and the second limiting roller 123 that cooperates with it, the second limiting roller 123 is located on the first side of the first transverse guide rail wall 31.

[0033] Specifically, the car 10 mainly comprises two parts: the car body 11 and the guide frame 12. The car body 11 has an internal space for accommodating people or objects; in one specific example, the car body 11 is rectangular. The guide frame 12 is fixed to the car body 11 and is equipped with multiple second limiting rollers 123. The guide frame 12 is connected to the guide rail via the second limiting rollers 123, and moves along the guide rail under the constraint of the second limiting rollers 123. The guide frame 12 is located between the longitudinal guide rail walls 32 of the two guide rails. The second limiting rollers 123 on it engage with the guide rail surface from the inner side between the two guide rails. Therefore, the guide frame 12 does not need to laterally cross to the outer side of the two guide rails to engage with them, thus reducing the span of the guide structure, making the structure simpler and more reliable. In addition, the guide frame 12 can enter between the two guide rails, allowing the car body 11 to be closer to the guide rails, resulting in a more compact structure.

[0034] In one embodiment of this application, reference is made to Figure 3The guide rail 30 includes a first transverse guide rail wall 31, a second transverse guide rail wall 33, and a longitudinal guide rail wall 32. The second transverse guide rail wall 33 is positioned opposite the first transverse guide rail wall 31, and the longitudinal guide rail wall 32 connects the first transverse guide rail wall 31 and the second transverse guide rail wall 33. The second limiting roller 123 on the guide frame 12 is located between the first transverse guide rail wall 31 and the second transverse guide rail wall 33, and cooperates with each guide rail wall from the inside between the two guide rails. The multiple first limiting rollers 23 respectively press the first transverse guide rail wall 31, the second transverse guide rail wall 33, and the longitudinal guide rail wall 32, thereby restricting the guide frame 12 on the two guide rails, and under the restriction of the second limiting rollers 123, the guide frame 12 moves along the guide rails.

[0035] refer to Figure 4 and Figure 5 In one embodiment of this application, the guide frame 12 includes two vertical arms 121 and several horizontal arms 122. The two vertical arms 121 extend vertically, and the horizontal arms 122 are located between the two vertical arms 121. The second limiting roller 123 is arranged on the two vertical arms 121. The drive device 20 is connected to the horizontal arms 122.

[0036] Specifically, the two vertical arms 121 are located close to the inner sides of the two guide rails, and the second limiting rollers 123 on the two vertical arms 121 respectively cooperate with the guide rails on both sides. In addition, the horizontal arm 122 between the two vertical arms 121 connects the two vertical arms 121, thereby forming an integral guide frame 12. (Reference) Figure 4 The drive unit 20 is connected to the guide frame 12 via the cross arm 122, thereby forming a connection with the car 10.

[0037] refer to Figure 4 In one embodiment of this application, the guide frame 12 is fixedly connected to the bottom 11a of the car 10. The bottom 11a of the car 10 is used to support people or objects in the interior space of the car. The load supported by the bottom 11a of the car 10 can be transferred to the guide frame 12, and then transferred by the guide frame 12 to the drive device 20. Figure 4 In the structure shown, the guide frame 12 includes two vertical arms 121 and several horizontal arms 122. The two vertical arms 121 extend vertically, and the horizontal arms 122 are located between the two vertical arms 121. The bottom 11a of the car 10 is fixedly connected to the lower ends of the two vertical arms 121.

[0038] In one embodiment of this application, the guide frame 12 of the car 10 and the mounting bracket 21 of the drive unit 20 are movably connected to allow relative rotation between the car 10 and the drive unit 20. In one technical solution, when the embedded rail-type elevator equipment is applied on a curved track, the angle between the car 10 and the drive unit 20 can change to adapt to the curvature of the track.

[0039] In one embodiment of this application, the guide frame 12 of the car and the mounting bracket 21 of the drive device 20 are connected by a connecting arm 40, and the connecting arm 40 is hinged to both the guide frame 12 and the mounting bracket 21; the connecting arm 40 drives the drive wheel 22 of the drive device 20 to press against the guide rail. Here, the connecting arm 40 has a certain angle, and the force it applies to the drive device 20 can make the drive wheel 22 press against the guide rail 30. When the drive source 25 outputs power, the drive wheel 22 rotates, and moves up and down by means of the friction with the surface of the guide rail 30.

[0040] refer to Figure 4 and Figure 6 In one embodiment of this application, the drive device 20 further includes several movable supports 24, with first limiting rollers 23 arranged on the movable supports 24, and the movable supports 24 hinged to the mounting frame 21. The movable supports 24 can be adaptively adjusted so that each of the first limiting rollers 23 on them remains tightly engaged with the guide rail.

[0041] refer to Figure 4 and Figure 6 In one embodiment of this application, the drive device 20 has a drive wheel 22 on each of the two guide rails; the drive source 25 is a motor, arranged between the drive wheels 22 on both sides; the motor has output terminals on both sides to drive the drive wheels 22 on both sides respectively. In this design, the motor has two output terminals on both sides, the first output terminal and the second output terminal are the two ends of the motor output shaft, which can output power synchronously to drive the drive wheels on both sides synchronously, so that the drive wheels on both sides keep rotating synchronously, and the two drive wheels 22 cooperate with the two guide rails respectively. The above motor drive scheme is more compact in structure and lower in cost because the two drive wheels corresponding to the two guide rails share a single motor, and it can ensure the synchronous rotation of the two drive wheels.

[0042] The embedded rail elevator equipment provided in this application is constructed based on two guide rails, which include a first transverse guide rail wall and a longitudinal guide rail wall. The first limiting roller of the drive device and the second limiting roller of the car are arranged between the longitudinal guide rail walls of the two guide rails, which reduces the span of the guide structure, making the structure simpler and more reliable.
