Description

Technical Field

[0001] This utility model relates to the field of aerial rail transit equipment technology, and in particular to a track mechanism for a small suspended monorail aerial rail vehicle. Background Technology

[0002] Suspended rail transit (skyrail) boasts significant advantages due to its unique design: low construction cost (approximately 1 / 1000th that of a subway), short construction period (1-2 years), strong spatial adaptability (requiring only pillars for space), suitability for mountainous areas and densely populated urban areas, environmental friendliness and energy conservation (low noise and lower energy consumption than subways). These characteristics make it widely applicable in various scenarios such as urban commuter trunk lines, tourism, airport connections, and industrial logistics.

[0003] Looking ahead, suspended monorail systems are evolving from a distinctive mode of transportation to a crucial supplement to urban backbone networks, possessing immense potential. Their development direction lies in deepening green technologies (such as hydrogen energy and battery optimization) and intelligent technologies (AI scheduling and predictive maintenance), while promoting multi-modal integration (such as seamless integration with subways). However, their development also faces core challenges: relatively limited peak-hour capacity (requiring improvement through increased train formations), reliance on passive solutions for high-altitude rescue mechanisms, and the long-term cost issues associated with initial battery power supply.

[0004] The applicant discovered through searches that, in the area of ​​track structure innovation, Chinese patent (CN206646341U) discloses a composite track beam that uses combined rolled unequal-sided H-beams to improve manufacturing precision and structural strength while reducing steel consumption. Chinese patent (CN206856708U) discloses a built-in track with a running surface designed as an inclined plane (5–20°), which reduces lateral sway through a self-guiding function, eliminating the need for additional guide wheels. Chinese patent (CN206885036U) discloses a cableway-style track with a wear-resistant arc surface (circular / elliptical arc) on the cableway surface, matching the wheel profile to achieve self-stabilization and noise reduction.

[0005] In summary, the following problems still exist in controlling suspended rail transit: Stability and noise control: At high speeds, the vehicle exhibits significant lateral sway, as disclosed in Chinese patent (CN206856708U), requiring multiple sets of auxiliary wheels / hydraulic dampers for compensation, increasing system complexity. Friction between the guide wheels and the track generates high-frequency noise, as described in Chinese patent (CN206885036U). While inclined / curved surface designs can mitigate this, they do not fundamentally solve the problem.

[0006] Manufacturing and maintenance costs: Composite track beams require precision rolling and welding, as shown in Chinese patent (CN206646341U), making processing difficult; cableway suspension systems, such as those disclosed in Chinese patent (CN206885036U), have cumbersome maintenance requirements for their tie rod / crossbar structures. Active guidance devices, such as those disclosed in Chinese patent (CN207997856U), rely on rotary drive motors and reducers, increasing the potential for failure.

[0007] Based on the above needs, the industry urgently needs to provide a miniaturized aerial rail transit system, especially a new low-cost rail mechanism that needs to be designed for cost control and commercialization. Utility Model Content

[0032] Please see Figures 1 to 3 This embodiment discloses a track mechanism 100 for a small suspended monorail aerial railcar. The track mechanism 100 of this embodiment has the following characteristics in its application scenarios: The suspended aerial vehicle features a monorail structure, unlike existing dual-rail structures. The total weight of the suspended aerial vehicle, including its own weight and load capacity, does not exceed 100 kg. Depending on the application requirements, the number of axles and wheel sets can be increased, and it can also be a cascaded box structure. Its design goal is to reduce the requirements of the track by tailoring the vehicle to specific application scenarios, keeping the track's load-bearing capacity within the range of 100-150 kg / m, thereby reducing track costs and facilitating large-scale commercialization.

[0033] The track mechanism 100 of the small suspended monorail aerial railcar includes: a first support part 1, a second support part 2, a first limiting part 3, a second limiting part 4, a first track part 5, and a second track part 6. The first support part 1 and the second support part 2 together form a support surface for suspending the suspension roller 10 of the aerial vehicle, and a gap is provided between the first support part 1 and the second support part 2. The first limiting part 3 is connected to the bottom of the first supporting part 1, the second limiting part 4 is connected to the bottom of the second supporting part 2, and a gap space 7 is provided between the first limiting part 3 and the second limiting part 4. The first track portion 5 is connected to the bottom of the first limiting portion 3, and the second track portion 6 is connected to the bottom of the second limiting portion 4. The first track portion 5 and the second track portion 6 together form a drive contact surface for the drive wheel of the aerial vehicle to abut and drive.

[0034] In this embodiment, the first support part 1 and the second support part 2 work together to support the suspension rollers 10 of the aerial vehicle. The aerial vehicle is suspended on the track mechanism by the suspension rollers 10. The first support part 1 and the second support part 2 also provide guidance for the movement of the aerial vehicle, so that it always moves along the direction of the track mechanism, realizing the rail transit drive mode.

[0035] The reserved gap between the first support part 1 and the second support part 2 is used to pass through the cantilever 20 of the aerial vehicle. The top of the cantilever 20 is connected to the suspension roller 10, and the bottom is connected to the vehicle body. The cantilever 20 passes through the space of the reserved gap to achieve the suspension connection.

[0036] A gap space 7 is provided between the first limiting part 3 and the second limiting part 4. The gap space 7 has a certain length in the vertical direction and is used to provide anti-sway limiting for the movement of the aerial vehicle. Specifically, the cantilever 20 passes through the gap between the first support part 1 and the second support part 2 and continues to pass through the gap space 7. Since the gap space 7 has a certain height in the vertical direction, the cantilever 20 is always located within the gap space 7 during the movement of the aerial vehicle. When the aerial vehicle is running in a non-linear track section, or when it shakes due to environmental disturbances, the limiting effect of the gap space 7 on the cantilever 20 can prevent the aerial vehicle from swinging too much. On the other hand, the gap space 7 can also act in the opposite direction to make the aerial vehicle quickly return to its original position and maintain smooth movement.

[0037] The first track section 5 and the second track section 6 together form a driving contact surface, which is used to contact the active roller of the aerial vehicle. The two rely on friction to displace relative to the driving contact surface when the active roller is rotated in a controlled manner, so that the driving power of the aerial vehicle causes the aerial vehicle to move along the track through the action of the active roller and the driving contact surface.

[0038] Please refer to it again. Figure 2 The top of the first support part 1 is provided with a first support surface 11, and the top of the second support part 2 is provided with a second support surface 21. The first support surface 11 and the second support surface 21 are set at the same height, and the first support surface 11 and the second support surface 21 together form the support surface. Figure 2 The state shown is the position of the track mechanism 100 of the small suspended monorail aerial railcar in this embodiment in actual application. The left roller surface of the suspension roller 10 is attached to the first support surface 11, and the right roller surface of the suspension roller 10 is attached to the second support surface 21. Obviously, the wheel surface width of the suspension roller 10 is not less than the distance between the first support part 1 and the second support part 2.

[0039] Since the track mechanism 100 of the small suspended monorail aerial railcar in this embodiment is applied to the design of a single suspended roller 10 in the width direction of the track, the size requirements of the first support part 1 and the second support part 2 are smaller, the manufacturing materials are less, and the high load-bearing strength requirements can be maintained.

[0040] The first track section 5 has a first abutting surface 51 at its bottom, and the second track section 6 has a second abutting surface 61 at its bottom. The first abutting surface 51 and the second abutting surface 61 together form the driving abutting surface.

[0041] The drive contact surface is used to contact the drive rollers (or running wheels) of the aerial vehicle. In actual scenarios, the drive rollers of the aerial vehicle are located below the first contact surface 51 and the second contact surface 61, and the two rely on pressure to contact each other. The advantage of this design is that by placing the drive power of the aerial vehicle outside the track mechanism 100 of the small suspended monorail aerial railcar, the internal space of the track mechanism can be further reduced, the overall structural size can be reduced, and manufacturing materials can be reduced. In addition, since the drive rollers of the aerial vehicle are located below the drive contact surface, the contact pressure between the drive rollers and the drive contact surface can be flexibly adjusted as needed, and this pressure is not limited by the weight of the small vehicle body. In the horizontal travel section, the contact pressure between the two can be reduced to reduce the wear of the contact parts and power consumption. However, when the aerial vehicle is traveling on uphill or downhill sections, the contact pressure between the two can be actively increased to make it more stable and reliable, thereby improving the safety of the aerial vehicle's operation. Therefore, this design of placing the drive power outside the track is energy-saving, environmentally friendly, and can improve operational safety.

[0042] In this embodiment, the supporting surface and the driving contact surface are arranged parallel to each other. It is understood that in other embodiments, depending on the arrangement angles of the suspension rollers 10 and driving rollers of different aerial vehicles, the supporting surface and the driving contact surface may also be non-parallel. Furthermore, the first supporting surface 11, the second supporting surface 21, the first contact surface 51, and the second contact surface 61 not only include planar structures but also non-planar structures corresponding to the wheel surfaces of the suspension rollers 10 and the driving rollers.

[0043] Specifically, the distance between the first support part 1 and the second support part 2 is in the range of 0.5 cm to 2 cm.

[0044] The lateral width of the space between the first limiting part 3 and the second limiting part 4 ranges from 0.5 cm to 2 cm.

[0045] In other embodiments, the lateral width range of the distance between the first support part 1 and the second support part 2, and the interval space between the first limiting part 3 and the second limiting part 4, can be increased or decreased according to the vehicle and the application scenario.

[0046] Please refer to it again. Figure 1 and Figure 2 This is the first specific implementation structure of the track mechanism 100 of the small suspended monorail aerial railcar in this embodiment, that is, the first support part 1, the second support part 2, the first limiting part 3, the second limiting part 4, the first track part 5 and the second track part 6 are all plate-shaped structural members.

[0047] The first limiting part 3 is formed by a vertical bend from the edge of the first supporting part 1, and the second limiting part 4 is formed by a vertical bend from the edge of the second supporting part 2. The first track part 5 is formed by a vertical bend from the bottom edge of the first limiting part 3 outwards, and the second track part 6 is formed by a vertical bend from the bottom edge of the second limiting part 4 outwards.

[0048] Furthermore, the first support part 1, the second support part 2, the first limiting part 3, the second limiting part 4, the first track part 5, and the second track part 6 are integrally formed structures. Of course, the first support part 1, the second support part 2, the first limiting part 3, the second limiting part 4, the first track part 5, and the second track part 6 can also be independent parts assembled by welding or other methods to form a track mechanism.

[0049] Furthermore, the first support part 1 and the second support part 2 are connected together by a bridging part 8, and the bridging part 8 is located on the top side of the first limiting part 3 and the second limiting part 4. That is, the bridging part 8 is located above the first support part 1 and the second support part 2. When the track mechanism 100 of the small suspended monorail aerial railcar of this embodiment is constructed into a track network on the ground, the track structure can be suspended in the air by steel cables or other support structures. Since the track mechanism 100 of this small suspended monorail aerial railcar is applied to small aerial vehicles, it can be implemented using low-cost support structures such as steel cables, further reducing the construction cost of this type of track and facilitating its large-scale commercialization.

[0050] Please refer to it again. Figure 3 This is another implementation structure of the track mechanism 100 for a small suspended monorail aerial railcar. It is composed of two square tube profiles and connecting plates. The parallel square tube profiles are set at the same height. The top surfaces of the two square tube profiles are a first support surface 11 and a second support surface 21, respectively, and the bottom surfaces are a first abutment surface 51 and a second abutment surface 61, respectively. A gap space 7 is reserved between the two square tube profiles. The side walls of the two square tube profiles on both sides of the gap space 7 are a first limiting part 3 and a second limiting part 4, respectively. Suspension rollers 10 are rotatably supported on the first support surface 11 and the second support surface 21. A cantilever 20 passes through the gap space 7, and its bottom is connected to a small vehicle body. The two parallel square tube profiles are fixedly connected by multiple connecting plates, which are the bridging parts 8. In this embodiment, the square tube profiles and connecting plates are all existing conventional profiles, and their processing and assembly costs are extremely low, which can reduce track costs.

[0051] As can be seen from the two specific implementation structures above, the track mechanism 100 of the small suspended monorail aerial railcar in this embodiment has a simple structure, is suitable for small aerial railcars, and can significantly reduce construction costs, thereby facilitating rapid large-scale commercialization.

[0052] The track mechanism of the small suspended monorail aerial railcar in this embodiment simplifies the track structure design of the suspended monorail aerial railcar, combines the characteristics of small railcars, significantly reduces track costs, and can maintain the stability, reliability and safety requirements of the small railcar.

[0053] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
