Description

Technical Field

[0001] This invention relates to a suspension track, and more particularly to a steel cable composite track. Background Technology

[0002] Currently, traditional aerial suspended rail systems for transporting people and goods generally suffer from technical defects such as complex structure, large weight, high installation and maintenance costs, and insufficient operational stability.

[0003] Existing tracks mostly adopt rigid beam frame integral support structure, which relies on dense support columns for fixation. This not only consumes a lot of materials and has a long construction period, but also makes them prone to deflection and deformation when erected over long distances, affecting the smoothness of wheel sliding. Some track systems use a single steel cable suspension, but the connection strength between the steel cable and the track is insufficient, making them prone to swaying and deviation during operation, resulting in poor safety and stability.

[0004] Meanwhile, traditional track cross-sections are of a single type, with poor ventilation and heat dissipation performance and low material utilization, making them unsuitable for passenger and cargo transportation needs in different scenarios. Their overall versatility and economy need to be improved.

[0005] Purpose of the invention

[0006] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a steel cable composite track. The steel cable composite track is reasonably designed, which helps to simplify the track support structure, reduce the track's self-weight and material costs, and achieve stable erection over long distances and large spans.

[0007] The technical solution of the present invention is as follows:

[0008] A steel cable composite track, characterized in that: it includes a steel cable suspended on a supporting column and a track connected to the steel cable, the track having wheels capable of traveling thereon, the wheels being connected to a suspended carriage carrying people or goods via a connecting arm.

[0009] Preferably, the aforementioned steel cables include only main steel cables or auxiliary steel cables.

[0010] Preferably, the aforementioned steel cable includes a main steel cable, an auxiliary steel cable, and multiple suspension rods connecting the main steel cable and the auxiliary steel cable.

[0011] Preferably, the track is a C-shaped track with the slot facing laterally. An auxiliary steel cable is partially embedded in the upper part of the C-shaped track. The part of the auxiliary steel cable that is not embedded in the C-shaped track is fixedly connected to the lower end of the suspension rod. A wheel is slidably connected in the C-shaped slot of the C-shaped track. The wheel is hinged to the upper end of the connecting arm. The lower end of the connecting arm is connected to the suspended carriage.

[0012] Preferably, the groove wall of the C-shaped track is provided with a through groove to facilitate ventilation and heat conduction and reduce material usage.

[0013] Preferably, another set of C-shaped tracks is fixed on the back side of the C-shaped track. Wheels are slidably connected in the C-shaped grooves of both sets of C-shaped tracks. Each wheel is hinged to the upper end of a connecting arm, and the lower end of the connecting arm is connected to the suspended carriage.

[0014] Preferably, the track is a C-shaped track with the groove facing downwards, and wheels slide on both sides of the C-shaped track.

[0015] Preferably, the track has a circular cross-section, and the upper end of the connecting arm is connected to a C-shaped channel steel that can accommodate the lower part of the track. Two sets of inclined wheels are provided at the slot of the channel steel, and the wheels abut against the circular track surface.

[0016] Preferably, the cross-section of the track is I-shaped, and the wheels are arranged on both sides of the I-shaped track, with the wheels abutting against the upper surface of the lower wing of the I-shaped track.

[0017] Preferably, the track is a truss with a triangular cross-section. The upper end of the truss is fixedly connected to a suspension rod, and the upper end of the suspension rod is connected to a main steel cable. Wheels are slidably connected to the trusses on both sides of the lower part of the truss, and the two wheels are hinged to the upper part of the connecting arm respectively.

[0018] Preferably, the aforementioned steel cable is connected to the upper end of the inclined steel cable, and the lower end of the inclined steel cable is connected and fixed to the ground.

[0019] The beneficial effects of this invention are:

[0020] 1. The steel cable and track composite structure is used to replace the traditional rigid beam frame, which greatly reduces the amount of materials used, reduces the self-weight and construction and maintenance costs, and is suitable for long-distance and large-span erection, achieving lightweight structure and lower cost;

[0021] 2. By combining the main steel cable, auxiliary steel cable and suspension rod for support, or by reinforcing with inclined steel cable, the overall rigidity and stability of the track are improved, avoiding swaying and deformation during operation, ensuring smooth wheel sliding and carriage safety, and achieving stable support and safe operation;

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] A steel cable composite track includes a steel cable suspended on a support column 1 and a track 2 connected to the steel cable. Wheels 3 are slidably connected to the track 2. The wheels are connected to a suspended carriage 5 carrying people or goods via a connecting arm 4. The support column 1 can be a metal frame, concrete frame, etc. erected on the ground, in a river, etc.

[0043] The steel cable can consist of only the main steel cable 6 or the auxiliary steel cable 7, meaning that the track 2 is directly connected to the main steel cable or the auxiliary steel cable.

[0044] Another embodiment of the steel cable is that the steel cable includes a main steel cable 6, an auxiliary steel cable 7, and multiple suspension rods 8 connecting the main steel cable and the auxiliary steel cable. The main steel cable 6 and the auxiliary steel cable 7 can be steel cables.

[0045] One embodiment of the track (such as) Figure 1-3 As shown), track 2 is a C-shaped track with the slot facing laterally. The auxiliary steel cable 7 is partially embedded in the upper part of the C-shaped track. The part of the auxiliary steel cable that is not embedded in the C-shaped track is fixedly connected to the lower end of the suspension rod 8. A wheel 3 is slidably connected in the C-shaped slot of the C-shaped track. The wheel 3 is hinged to the upper end of the connecting arm 4. The lower end of the connecting arm 4 is connected to the suspended carriage 5.

[0046] A through groove 9 is provided on the groove wall of the C-shaped track. This through groove 9 facilitates ventilation and heat conduction and reduces the amount of material used. A reinforcing rib 13 is provided on the back side of the groove wall of the C-shaped track.

[0047] To increase connection stability, another set of C-shaped tracks is fixed to the back of the C-shaped track. Wheels are slidably connected in the C-shaped grooves of both sets of C-shaped tracks. Each wheel is hinged to the upper end of a connecting arm, and the lower end of the connecting arm is connected to the suspended carriage.

[0048] Another embodiment of the track (such as) Figure 4 As shown in the figure, the track is a C-shaped track with the groove facing downwards, and wheels slide on both sides of the C-shaped track.

[0049] Another embodiment of the track (such as) Figure 5 As shown), the cross-section of the track is circular. The upper end of the connecting arm is connected to a C-shaped channel steel 10 that can accommodate the lower part of the track. Two sets of inclined wheels are provided at the slot of the channel steel, and the wheels abut against the circular track surface.

[0050] Another embodiment of the track (such as) Figure 6 As shown), the track is a truss with a triangular cross-section. The upper end of the truss 11 is fixedly connected to the suspension rod 8. The upper end of the suspension rod is connected to the main steel cable. Wheels are slidably connected to the trusses on both sides of the lower part of the truss. The two wheels are hinged to the upper part of the connecting arm.

[0051] Another embodiment of the track (such as) Figure 11 As shown), the cross-section of the aforementioned track 2 is I-shaped, and the wheels are arranged on both sides of the I-shaped track, with the wheels abutting against the upper surface of the lower wing of the I-shaped track.

[0052] Another embodiment of the track (such as) Figure 14 As shown), the cross-section of the track 2 is C-shaped, with the groove of the C-shaped track facing downwards. Wheels 3 are respectively embedded on both sides of the C-shaped track. The wheel 3 is conical, and the shape of the two sides of the C-shaped track corresponds to the conical wheel. The two wheels are rotatably connected to the C-shaped grooves on both sides of the upper end of the connecting arm 4. A rectangular groove is provided at the upper end of the connecting arm 4. The track 2 is provided with a driving magnetic levitation device 19 that is embedded in the rectangular groove. The driving magnetic levitation device 19 is the prior art (such as the one disclosed in patent application number CN202310010718.8, invention title: anti-detachment permanent magnet levitation running mechanism and its working method). That is, after being powered on, the driving magnetic levitation device 19 can drive the connecting arm 4 to move relative to the track 2.

[0053] like Figure 7-10 The present invention relates to a structural design at the track-changing position (i.e., transferring from one track to another). At this position, an auxiliary steel cable 7 is fixedly embedded in a hanging plate 14. One side of the hanging plate 14 has a through hole for installing a rotating rivet 15, and the other side of the hanging plate 14 has an arc-shaped groove 16 for installing a suspension bolt. The lower ends of the rotating rivet 15 and the suspension bolt are fixedly connected to the upper part of the track-changing track 21. That is, when track changing is required, the track-changing track 21 rotates around the rotating rivet 15 so that the front end of the track-changing track 21 is still connected to the first track, while the rear end of the track-changing track 21 is connected to the second track. The first track and the second track are misaligned, thus completing the track-changing action.

[0054] like Figure 12 As shown, a flexible track 17 is set at the track changing position. A nut 18 is installed on the flexible track 17. The nut 18 is connected to a screw. The screw moves along the width direction of the track under power drive to realize track changing.

[0055] like Figure 13 The illustration shows an embodiment of parallel trajectory change.

[0056] To increase connection stability, the aforementioned steel cable is connected to the upper end of the inclined steel cable 12, and the lower end of the inclined steel cable is fixed to the ground.

[0057] The beneficial effects of this invention are:

[0058] 1. The steel cable and track composite structure is used to replace the traditional rigid beam frame, which greatly reduces the amount of materials used, reduces the self-weight and construction and maintenance costs, and is suitable for long-distance and large-span erection, achieving lightweight structure and lower cost;

[0059] 2. By combining the main steel cable, auxiliary steel cable and suspension rod for support, or by reinforcing with inclined steel cable, the overall rigidity and stability of the track are improved, avoiding swaying and deformation during operation, ensuring smooth wheel sliding and carriage safety, and achieving stable support and safe operation;

[0060] 3. Offers various track structures such as lateral C-shape, downward C-shape, circular, and triangular truss, which can be flexibly adapted to different passenger and cargo transportation scenarios, and have high versatility;

[0061] 4. The C-shaped track has through slots to optimize ventilation and heat dissipation, reduce track deformation due to heat, and further reduce material usage while improving structural durability;

[0062] 5. The wheels are hinged to the rails and connecting arms, and the symmetrical sliding design of multiple sets of wheels ensures that the suspended carriage is evenly stressed and runs smoothly without jamming.

[0063] 6. The entire assembly adopts a suspended type, which has low requirements for ground terrain. It can be quickly fixed by supporting columns and inclined steel cables, and is suitable for various complex environments such as mountains and cities.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
