[0010] The braking assembly includes a transmission arm, which is movably connected to the bottom of the first swing arm and the second swing arm, so that the transmission arm synchronously drives the first swing arm and the second swing arm to swing.

[0032] Suspended rail transit (skyrail) exhibits significant advantages due to its unique design, including low construction costs, short construction periods, and strong spatial adaptability. These characteristics make it widely applicable in various scenarios such as urban commuter trunk lines, tourism, airport connections, and industrial logistics. In existing suspended sky rail transit devices, braking between the suspended trolley and the elevated track typically relies on controlling the drive motor or brake discs that control the trolley's forward rollers. These braking methods generally depend on electrical control, which is prone to brake failure. Furthermore, existing brakes are mainly applied to load-bearing rail transit equipment operating above the elevated track. Therefore, based on the above requirements, this embodiment provides a braking device 100 for a suspended sky trolley.

[0033] Please see Figures 1 to 7 This embodiment discloses a braking device 100 for a suspended aerial vehicle, which includes: The track assembly 2 has a first bearing surface 211 at the top, a first driving contact surface 212 at the bottom, and a vertically penetrating guide groove 201. The first bearing surface 211 is a support surface structure for supporting the aerial trolley car and its accessories, and the first driving contact surface 212 is a planar structure for contacting the drive wheel of the aerial trolley's drive power mechanism to provide driving friction. The first bearing surface 211 is located at the top of the track assembly 2, while the first driving contact surface 212 is located at the bottom of the track assembly 2 opposite to the top bearing surface 211. Therefore, the first bearing surface 211 of the track assembly 2 is only used for load bearing, while the first driving contact surface 212 is only used to contact the drive power mechanism to provide friction. Compared to existing tracks where the drive mechanism needs to provide both load bearing and drive groove, this novel track assembly 2 has a simple structure, low cost, and reliable and stable operation.

[0034] The load roller assembly 1 includes a plurality of rollers 12, which roll against the first bearing surface 211. Obviously, the load roller assembly 1 is located directly above the track assembly 2. The load roller assembly 1 can move relative to the track assembly 2 and provides vertical support for the car and its auxiliary mechanisms of the suspended aerial vehicle during the movement.

[0035] The mounting assembly 3 includes a mounting plate 32, which is fixedly connected to the load roller assembly 1 through the guide groove 201. The mounting assembly 3 is connected to the load roller assembly 1 via the mounting plate 32, and the mounting plate 32 passes through the vertically arranged guide groove 201 on the track assembly 2, thus the mounting assembly 3 is located below the track assembly 2. When the load roller assembly 1 is moved under control, the mounting assembly 3 is simultaneously driven to move along the guide groove 201. A predetermined gap is reserved between the guide groove 201 and the mounting plate 32 to prevent the mounting plate 32 from contacting the groove wall of the guide groove 201 during movement and to prevent swaying in the direction perpendicular to the direction of movement, which would affect operational stability.

[0036] Braking assembly 4 is connected to the mounting assembly 3. When the braking surface 431 of the braking assembly 4 abuts against the first driving contact surface 212, braking is achieved between the mounting assembly 3 and the track assembly 2. That is, the braking assembly 4 acts on the first driving contact surface 212 on the track assembly 2 to achieve braking.

[0037] In this embodiment, a braking component 4 is designed for the track component 2 with a special structure. The braking surface 431 of the braking component 4 contacts the first driving contact surface 212 of the track component 2, thereby realizing the braking of the hanging component 3 and the load rolling component 1. The car of the suspended aerial vehicle is connected below the hanging component 3, so the braking component 4 realizes the braking of the aerial vehicle.

[0038] Please refer to it again. Figure 4 The braking assembly 4 includes a first swing arm 41 and a brake pad 43 connected to the top of the first swing arm 41. The middle part of the first swing arm 41 is rotatably connected to the hook assembly 3. When the first swing arm 41 is controlled to swing, it synchronously drives the brake pad 43 to abut against or move away from the first drive contact surface 212. When the brake pad 43 abuts against the first drive contact surface 212, frictional resistance is generated between the two. The braking assembly 4 is connected to the hook assembly 3, so at this time, the relative movement of the braking assembly 4 and the track assembly 1 stops, and the hook assembly 3 stops moving relative to the track assembly 2. Conversely, if the brake pad 43 disengages from the first drive contact surface 212 of the track assembly 2, the hook assembly 3 can move relative to the track assembly 2 under the drive of the drive mechanism, that is, drive the aerial trolley to move.

[0039] A lifting plate 42 is provided between the top of the first swing arm 41 and the bottom of the brake pad 43. The lifting plate 42 is slidably connected to the hanging assembly 3, so that the lifting plate 42 moves vertically up and down with the first swing arm 41. When the first swing arm 41 swings, its top end drives the lifting plate 42 to rise, and the brake pad 43 connected to the top of the lifting plate 42 rises synchronously, eventually causing the brake pad 43 to abut against the first driving contact surface 212 of the track assembly 1. In order to limit the lifting direction of the brake pad 43 and achieve accurate abutment between the brake pad 43 and the first driving contact surface 212 and reliability in the abutment state, the lifting plate 42 is slidably connected to the hanging assembly 3. The sliding connection structure between the two restricts the lifting plate 42 to move only in the vertical direction during the lifting process. The mounting assembly 3 is connected to the load roller assembly 1 via the mounting plate 32. The mounting plate 32 is matched with the guide groove 201 of the guide rail assembly 2. Therefore, the lifting plate 42, which is slidably connected to the mounting assembly 3, can improve the alignment accuracy of the brake pad 43 and the stability of the contact state with the first drive contact surface 212.

[0040] Please refer to it again. Figure 6 The lifting plate 42 includes a plate body 421 and guide posts 422 connected to the plate body 421. The hanging assembly 3 has a vertically extending guide hole, and the guide posts 422 are inserted into the guide hole. The plate body 421 is located between the top of the hanging assembly 3 and the bottom of the track assembly 2. To improve the connection stability between the lifting plate 42 and the hanging assembly 3, two guide posts 422 are provided on the plate body 421, and the two guide posts 422 are respectively located at both ends of the plate body 421 along its length. The guide posts 422 are perpendicular to the plate surface of the plate body 421.

[0041] Furthermore, the brake assembly 4 also includes a second swing arm 44, which is mirror-image of the first swing arm 41, and the middle portion of the second swing arm 44 is rotatably connected to the mounting assembly 3. (Please refer to...) Figure 5 The first swing arm 41 and the second swing arm 44 are arranged in a left-right mirror image, and the contact positions of the first swing arm 41 and the second swing arm 44 with the lifting plate 42 are also symmetrical. Similarly, the brake assembly 4 composed of the two guide pillars 422, the lifting plate 42, the first swing arm 41, and the second swing arm 44 is also symmetrical. This symmetrical structure can improve the smoothness and reliability of the braking action.

[0042] The brake assembly 4 further includes a transmission arm 45, which is movably connected to the bottom of the first swing arm 41 and the second swing arm 44, so that the transmission arm 45 synchronously drives the first swing arm 41 and the second swing arm 44 to swing. That is, the first swing arm 41 and the second swing arm 44 are driven by the transmission arm 45 to move up and down synchronously. For example, the transmission arm 45 can be a bicycle brake cable.

[0043] Please continue reading. Figure 6 The first swing arm 41 and the second swing arm 44 have the same structure. Taking the first swing arm 41 as an example, it includes: a transmission plate portion 412, a swing plate portion 413 that extends from the top of the transmission plate portion 412, and a rotating shaft portion 411 that extends vertically from the middle of the transmission plate portion 412. The rotating shaft portion 411 is rotatably connected to the hanging assembly 3. The transmission plate portion 412 and the swing plate portion 413 form a plate that is approximately L-shaped.

[0044] In another embodiment, the brake assembly 4 further includes a drive unit for driving the transmission arm 45 to reciprocate. The drive unit includes an electric or pneumatic power unit such as a cylinder, electric cylinder, hydraulic cylinder, or motor.

[0045] In another embodiment, the first swing arm 41 and the second swing arm 44 can also be implemented by a transmission structure combining a lifting rod and a sleeve. The sleeve is fixedly connected to the hanging assembly 3, the lifting rod passes through the sleeve, the top end of the lifting rod is connected to the lifting plate 42 or directly connected to the brake pad 43, and the bottom end of the lifting rod is connected to the driving component. The driving component drives the lifting rod to move up and down so as to achieve the contact or disengagement of the driving contact surface between the brake pad 43 and the track assembly 2.

[0046] Please refer to it again. Figure 1 and Figure 2 The load roller assembly 1 further includes a roller bracket 11, and a plurality of rollers 12 are rotatably connected to the roller bracket 11. Each roller 12 has an annular limiting protrusion 121 on its surface, which is inserted into the guide groove 201. Because the annular limiting protrusion 121 is inserted into the guide groove 201, the roller 12 is always restricted by the guide groove 201 during rolling. The roller 12 can only roll forward along the length of the guide groove 201 without disengaging from the track assembly 2.

[0047] Please see Figure 3The track assembly 2 includes a first track body 21 and a second track body 22. The first track body 21 and the second track body 22 are arranged parallel to each other at the same height, with a reserved gap between them, which is the guide groove 201. The first track body 21 and the second track body 22 have the same structure. The top of the first track body 21 is provided with a first bearing surface 211 and the bottom is provided with a first driving contact surface 212. The top of the second track body 22 is provided with a second bearing surface 221 and the bottom is provided with a second driving contact surface 222. The first bearing surface 211 and the second bearing surface 221 are arranged at the same height and together form a bearing surface. The first driving contact surface 212 and the second driving contact surface 222 are arranged at the same height and together form a driving contact surface.

[0048] The outer side of the first rail body 21 and the second rail body 22 near the guide groove 201 at the top is an arc-shaped surface. The radial cross section of the corresponding annular limiting protrusion 121 is an approximately V-shaped arc surface. During the sliding process of the roller 12 relative to the track assembly 2, it can achieve guidance. At the same time, if the roller 12 shakes or deviates, it can automatically reset under the guidance of the arc surface.

[0049] In this embodiment, both the first rail body 21 and the second rail body 22 are square steel, and they are fixedly connected by a U-shaped fixing plate 202.

[0050] like Figure 4 As shown, the mounting assembly 3 includes a mounting base 31 and a mounting plate 32 connected to the mounting base 31. The car of the aerial trolley (not shown) is fixedly connected to the mounting base 31. A power mechanism is provided on the top of the car, which is used to drive the car to move relative to the track assembly 2. The output shaft of the power mechanism or the synchronous belt connected to the output shaft roller abuts against the drive contact surface at the bottom of the track assembly 2.

[0051] Embodiments of the present invention also provide a suspended aerial vehicle, the suspended aerial vehicle including a braking device as described in any of the above embodiments, and a car connected to the suspension assembly. A power mechanism is provided on the top of the car, which drives the car to move relative to the track assembly 2. The output shaft of the power mechanism or a synchronous belt connected to the output shaft roller abuts against the drive contact surface at the bottom of the track assembly 2.

[0052] Please refer to it again. Figures 1 to 7 The braking device for the suspended aerial vehicle in this embodiment has the following advantages compared with the prior art: 1. Unlimited Braking Force: The placement of the braking device within the track system is crucial. Through its combination with track components, load roller components, and the braking device, an unlimited braking force can be achieved. The load roller components and the braking device form a clamping structure around the track components. The contact pressure between the brake pads and the track components is linearly related to the force output by the brake cable; the greater the braking force output by the brake cable, the greater the contact pressure between the brake pads and the track, and thus the greater the braking force. In contrast, traditional automobiles and rail locomotives rely on the locomotive's own weight to provide contact pressure between the wheelset and the track or ground. Their braking capacity is limited by the locomotive's weight and the coefficient of friction of the track, resulting in a definite upper limit to the braking force.

[0053] 2. The brake pads of this braking device are in horizontal contact with the track assembly, and the braking force and contact pressure are linearly related. It can provide a linear braking force similar to that of a disc brake, effectively avoiding the non-linearity of the braking force and tension provided by the brake cable in some cases, and can largely avoid the situation where the starting brake device of a traditional drum brake locks up.

[0054] The above examples are merely illustrative of the technical content of the present invention to facilitate easier understanding by the reader, but do not imply that the implementation of the present invention is limited to these examples. Any technical extensions or re-creations made based on the present invention are protected by the present invention. The scope of protection of the present invention is defined by the claims.
