Description

Technical Field

[0001] This invention relates to the field of aerial rail transit equipment technology, and in particular to a guiding device for a suspended aerial vehicle and the aerial vehicle thereof. Background Technology

[0002] Suspended rail transit (skyrail) boasts 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.

[0003] In existing suspended aerial rail transit devices, the power mechanism driving the trolley forward typically uses motor-driven rollers. These rollers rotate and are supported by the elevated track. Therefore, the rollers of the power mechanism need to provide both longitudinal support and forward propulsion for the suspended trolley. This results in a complex trolley structure and a corresponding complex elevated track structure, leading to high construction costs and hindering widespread adoption. To address this, a novel track structure is proposed. In this new structure, the support and power drive are located at the top and bottom of the track, thereby simplifying the track and trolley structure, reducing construction costs, and improving operational safety and reliability.

[0004] However, due to the novel track structure design, when the aerial trolley splits and changes tracks, the rollers supporting the trolley mechanism cannot ensure that the movement paths are the same. If rollers in different positions enter different tracks, it will cause damage to the trolley and safety accidents. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a guiding device for a suspended aerial vehicle and a suspended aerial vehicle, so as to solve the technical problem of track changing guidance of existing suspended vehicles.

[0011] The guiding component includes a front link and a rear link, the rear end of the front link is movably connected to the front end of the rear link, and both the front link and the rear link are provided with a left guide surface and a right guide surface parallel to the groove wall of the guide groove.

[0012] The front and rear links have the same structure, both including a chain plate body. The front end of the chain plate body has a vertically opened locking groove, and the rear end of the chain plate body has a locking piece. The locking piece of the front link is inserted into the locking groove of the rear link. The chain plate body has a strip hole that passes through the locking groove. The locking piece has a screw that passes through the strip hole, so that the front and rear links are movably connected.

[0013] The front end of the chain plate body is provided with several horizontally opened strip-shaped notches, and the snap-fit ​​piece is provided with several raised strips that are aligned with the strip-shaped notches; the strip-shaped notches of the front chain link and the raised strips of the rear chain link are snapped together.

[0016] The present invention relates to a guiding device for a suspended aerial vehicle and the aerial vehicle thereof, wherein several mounting plates are fixedly connected by a guiding assembly. By utilizing the guiding surface of the guiding assembly and the guiding groove of the track assembly, at the track bifurcation point, the guiding assembly guides all the mounting plates to move along the same path and smoothly enter the bifurcation track, thus avoiding safety accidents.

[0017] This guiding device for suspended aerial trolleys is the core mechanism for track-separating actions during locomotive network operation, effectively supporting locomotives or locomotive formations to autonomously select their operating paths within the track network.

[0032] Suspended rail transit (skyrail) boasts 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.

[0033] In existing suspended aerial rail transit devices, the power mechanism driving the trolley forward typically uses motor-driven rollers. These rollers rotate and are supported by the elevated track. Therefore, the rollers of the power mechanism need to provide both longitudinal support and forward propulsion for the suspended trolley. This results in a complex trolley structure and a corresponding complex elevated track structure, leading to high construction costs and hindering widespread adoption. To address this, a novel track structure is proposed. In this new structure, the support and power drive are located at the top and bottom of the track, thereby simplifying the track and trolley structure, reducing construction costs, and improving operational safety and reliability.

[0034] However, due to the novel track structure design, when the aerial trolley splits and changes tracks, the rollers supporting the trolley mechanism cannot ensure that their movement paths are the same. If rollers at different positions enter different tracks, it will cause damage to the trolley and safety accidents. Therefore, based on the above requirements, this embodiment provides a guide device 100 for a suspended aerial trolley.

[0035] Please see Figures 1 to 7This embodiment discloses a guide device 100 for a suspended aerial vehicle, which includes: a track assembly 2, a load roller assembly 1 disposed above the track assembly 2, and a guide assembly 3 disposed inside the track assembly 2.

[0036] The track assembly 2 has a load-bearing surface at the top, a driving contact surface at the bottom, and a vertically penetrating guide groove 210. The load-bearing surface is a supporting structure for supporting the aerial trolley car and its accessories, and the driving contact surface is a planar structure for contacting the drive wheel of the aerial trolley's drive power mechanism to provide driving friction. The load-bearing surface is located at the top of the track assembly 2, while the driving contact surface is located at the bottom of the track assembly 2 opposite the top load-bearing surface. Therefore, the load-bearing surface of the track assembly 2 is only used for load bearing, while the driving contact surface 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 driving groove, this novel track assembly 2 has a simple structure, low cost, and reliable and stable operation.

[0037] The load roller assembly 1 includes a plurality of rollers 12, which roll against the bearing surface. 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.

[0038] A mounting plate 4 is fixedly connected to the load roller assembly 1 through the guide groove 210. The mounting plate 4 is connected to the load roller assembly 1 and passes through the vertically arranged guide groove 210 on the track assembly 2. When the load roller assembly 1 moves under control, it synchronously drives the mounting plate 4 to move along the guide groove 210. A predetermined gap is reserved between the guide groove 210 and the mounting plate 4 to prevent friction and collision between the mounting plate 4 and the groove wall during movement, and also to prevent swaying in the direction perpendicular to the movement direction, which would affect operational stability. This mounting plate 4 ensures that the aerial trolley will never derail, improving operational safety.

[0039] The guide component 3 is connected in sequence to several of the mounting plates 4. The guide component 3 is located in the guide groove 210, so that the several mounting plates 4 always follow the path of the mounting plate in front. That is, when the trolley enters the branch track, all the rollers 12 can enter the same branch track in sequence.

[0040] Please refer to it again. Figures 1 to 4The 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 210. 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.

[0041] 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 23.

[0042] The aforementioned track component 2 is the main track of the trolley track. One end of the main track is connected to a first sub-track 201 and a second sub-track 202. The structure of the first sub-track 201 and the second sub-track 202 is the same as that of the main track. The junction of the main track and the sub-track forms a Y-shaped fork, which is used to guide the aerial trolley to different paths in order to realize the track switching of the suspended trolley.

[0043] like Figure 2 As shown, the load roller assembly 1 includes several rollers 12 arranged sequentially. When the load roller assembly 1 enters the Y-shaped fork, due to the certain distance between the rollers 12 arranged sequentially, the existing trolley rapid track changing process cannot ensure that all rollers 12 can enter the same track. Therefore, this solution adds a guide assembly 3. Through the guiding effect of the guide assembly 3, all rollers 12 are guided to the same track, so that their movement paths are the same and safety accidents are avoided.

[0044] Please refer to it again. Figures 5 to 7 The guide component 3 has both flexible and rigid characteristics along its length. The guide component 3 with flexible and rigid characteristics can adapt to the non-straight track component 2, and at the same time provide a certain guiding force during the process of the trolley entering the track split. The rollers 12 at different positions will also have a certain curvature. The flexible guide component 3 can adapt well to track split and lane change, so that all the connecting plates 4 are guided to the same branch.

[0045] The guide assembly 3 includes a chain plate body 31, the top edge of which is provided with a plurality of upper limit stops 32, which extend horizontally to both sides of the track assembly 2 in the width direction. Figure 5 As shown in the assembly relationship, the upper limit part 32 is located above the support surface of the track assembly 2, which can prevent the guide assembly 3 from falling out of the guide groove 210.

[0046] The bottom edge of the guide component 3 is provided with a plurality of lower limit portions 33, which extend horizontally to both sides of the width direction of the track component 2. That is, the structure of the lower limit portion 33 is roughly the same as that of the upper limit portion 32. The lower limit portion 33 is located below the drive contact surface of the track component 2, which can prevent the guide component 3 from disengaging upward from the guide groove 210.

[0047] In other embodiments, the upper limit portion 33 and the lower limit portion 32 can also be other structures and other methods to limit the track assembly 2. The purpose is to keep the limiting guide assembly 3 at an appropriate distance from the guide groove 210 of the track assembly 2 during the movement of following the mounting plate 4, so as to prevent it from disengaging from the guide groove 210.

[0048] In this embodiment, the mounting plate 4 passes through the interior of the guide assembly 3 and is fixedly connected to the guide assembly 3. The mounting plate 4 passes through and is fixed to the guide assembly 3, thereby keeping the outer guide surface of the guide assembly 3 flat, so that the trolley can smoothly and stably enter the track.

[0049] like Figure 6 and Figure 7 As shown, the chain plate body 31 of the guide assembly 3 includes a front link 312 and a rear link 311. The rear end of the front link 312 is movably connected to the front end of the rear link 311. Both the front link 312 and the rear link 311 are provided with a left guide surface 302 and a right guide surface 301 parallel to the groove wall of the guide groove 210. The left guide surface 302 and the right guide surface 301 together form the guide surface of the guide assembly 3. They are distributed opposite to each other and are arranged approximately parallel to the side wall of the guide groove 210. In this embodiment, the left and right directions refer to the two directions perpendicular to the forward direction of the trolley, and the front end and rear end refer to the directions in front and behind the trolley's driving direction, respectively.

[0050] Obviously, the guide component 3 in this embodiment can be made by connecting multiple front links 312 and multiple rear links 311 end to end according to the required length, and is not limited to a combination structure of a single front link 312 and a single rear link 311.

[0051] The front link 312 and the rear link 311 have the same structure. Taking the rear link 311 as an example, it includes a chain plate body 310. The front end 313 of the chain plate body 310 is provided with a vertically opened locking groove 3132, and the rear end 312 of the chain plate body 310 is provided with a locking piece 3121. The locking piece 3121 of the front link 312 is inserted into the locking groove 3132 of the rear link 311. The chain plate body 310 is provided with a strip hole 3133 passing through the locking groove 3132. The locking piece 3121 is provided with a screw, and the screw passes through the strip hole 3133, so that the front link 312 and the rear link 311 are movably connected. The screw can move along its length within the strip hole 3133, thus enabling a movable connection between the front link 312 and the rear link 311. The guide component 3 of this structure can automatically deform to adapt to the current track structure during non-straight track and track entry processes, avoiding tensile damage to the guide component 3.

[0052] To prevent large vertical displacement between the front link 312 and the rear link 311, the front end 313 of the chain plate body 310 is provided with several horizontally opened strip-shaped notches 3131. The locking piece 3121 is provided with several raised strips 3122 that align with the strip-shaped notches 3131. The strip-shaped notches 3131 of the front link 312 and the raised strips 3122 of the rear link 311 engage with each other. Due to the limiting effect of the raised strips 3122 and the strip-shaped notches 3131, the front link 312 and the rear link 311 can be prevented from swaying in the vertical direction, and moderate mobility can be maintained along the length of the chain plate body 310.

[0053] The above-described chain plate body 310 structure design has the following advantages: 1. Horizontal flexibility: Horizontal flexibility allows the locomotive to lengthen the guide device in curved tracks to adapt to the chord-arc difference when the track changes from a straight line to an arc.

[0054] 2. The degree of freedom of bending at a small angle in the vertical direction is to meet the requirement that different wheel sets are not on the same horizontal plane when the locomotive is climbing or going downhill, and a certain degree of freedom of angle is required.

[0055] 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.

[0056] like Figure 4As shown, the top of the mounting plate 4 is connected to the roller bracket 11, and the car of the aerial trolley (not shown) is fixedly connected to the bottom of the mounting plate. 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.

[0057] An embodiment of the present invention also provides a suspended aerial vehicle, the suspended aerial vehicle including a guide device as described in any of the above claims, 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.

[0058] This embodiment describes a guiding device for a suspended aerial trolley and the trolley itself. Several mounting plates are fixedly connected using a guiding assembly. The guiding surface of the assembly engages with the guiding groove of the track assembly. At track forks, the guiding assembly guides all mounting plates to move along the same path, smoothly entering the forked track and avoiding safety accidents. This guiding device for the suspended aerial trolley is the core mechanism for track-splitting operations of locomotives in track network operation, effectively supporting locomotives or locomotive formations to autonomously select their operating paths within the track network. Its simple structure and stable guidance effectively prevent the risk of safety accidents caused by a group of locomotives entering different forks.

[0059] 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.
