Description

Technical Field

[0001] This utility model relates to aerial transportation technology, and in particular to an aerial cableway gantry self-operating and track-changing system. Background Technology

[0002] With the rapid development of modern society, practical technologies in various fields have seen significant improvements and advancements. However, aerial transportation technology remains largely confined to a mode of transport where vehicles are pulled by a drive-driven circulating steel cable or a separate steel rope. This traditional technology suffers from bulky machinery, complex manufacturing and installation procedures, and an outdated and simplistic approach, failing to meet the diverse needs of today's markets. For example, challenges exist in traversing narrow mountain streams, river crossings, and hilly slopes for both personnel and cargo transportation. Society urgently needs a simple, easy-to-implement, convenient, and efficient innovative aerial transportation technology. Summary of the Invention

[0003] This utility model provides a novel aerial cableway gantry self-operating and track-changing system transportation technology solution, fundamentally changing the old aerial cableway technology mode and concept of steel cable traction vehicles. It effectively solves the aforementioned social needs and challenges. This technical solution includes: a chain plate with axle cable buckles and its components that combine the chain track and steel cable into a single unit (including structural components that vary slightly for different scenarios), forming a 'cableway' structure with different modes of steel cable chain track combination (single cable double chain standard type, double cable triple chain heavy-duty type, and double cable single chain lightweight simplified type).

[0004] Then, with both ends of the cable rail in a taut state, the cable rail is fixed to the cable rail I-beam bridge frame using cable rail assemblies (including chain plates with axle cable buckles). The cable rail I-beam bridge frame combined with a trough-type triangular frame is set at the upper end of the bridge frame piles, forming a pile-pile span support structure for the cable rail overhead line.

[0005] A self-running gearbox is installed above the cable rail. Inside the gearbox, two sets of functional wheels of various types are installed at both ends of the longitudinal direction. These wheels are driven by a through shaft and run through the corresponding cable rail. These include cable load wheels for the steel cables, sprockets for the chain tracks, and chain track limit wheels below the chain tracks (which prevent the sprockets from derailing on steep slopes). The power gear set and gear train linkage structure inside the gearbox are driven by a reversible motor on the outside of the gearbox, which constitutes the self-running function of the gearbox along the cable rail.

[0006] The upper end of the C-shaped boom is installed in the boom hinge seat above the self-running gearbox, and the lower end is hooked to the boom hinge seat above the hoisting box or bucket, forming a hooking structure between the self-running gearbox and the hoisting box / bucket hinge seat.

[0007] A sensing and control energy storage box is installed below the hoisting box or above the hoisting bucket. It contains a battery and electrical sensing and control device, which constitutes the power storage function of the hoisting box and hoisting bucket being driven by a self-running gearbox for reciprocating operation, as well as the sensing and control operating system device.

[0008] The cable-stayed long-distance line is equipped with segmented switching stations with gantry cranes that can change track. The stations are mainly equipped with components such as: track-changing piles, magnetic limit rocker arms, lifting beams, track-changing platforms, and matching track-changing gantry cranes, track-changing gantry cranes, and snap-lock seats, which together form the segmented track-changing system.

[0009] This utility model is technologically advanced and has a bold innovative approach. It has fundamentally changed the existing technological model. Its structure is simple, easy to manufacture, and low in cost, making it an original and innovative technology that can be widely used in society. Attached Figure Description

[0044] Figure 1-2 (3D rendering) The self-operating gearbox 2, with its notch facing downwards, longitudinally spans above the single-cable double-chain cable rail 1. The upper end of the C-shaped boom 3 is installed in the boom hinge seat 4 above the gearbox, and the lower end is hooked to the boom hinge seat 4 above the hoisting box 5 or the hoisting bucket 8. The sensing and control storage box 6, located below the hoisting box and above the hoisting bucket, contains sensing and control electrical appliances and batteries, serving as the control device and power source for driving the reversible motor 7 located outside the gearbox.

[0045] Figure 3-9The chain plate with axle cable buckle 11 shown (i.e., the integrated chain plate with chain shaft 13) together with the inner chain plate 14, outer chain plate 15, chain shaft sleeve 19, and chain shaft roller 18 of the component form two integrated cable buckle chain rails 10. The matching component cable buckle clamping slider 16 or cable buckle bow slider 1601 is used, that is, the cable buckle pin 12 and the pin 17 fasten the two cable buckle chain rails to both sides of the steel cable 9 as a whole (the steel cable where the cable buckle is fastened is locally hardened by tin infiltrating the gap between the steel wires, which enhances the clamping effect of the cable buckle), thus forming a single cable double chain rail (standard type) structure.

[0046] Figure 10-14 The self-operating gearbox 2 shown has two sets of corresponding functional wheels arranged longitudinally at both ends, with gear shafts 24 running through them. The centrally located cable support wheel 31, corresponding to the cable 9, has a groove that fits across the upper half of the cable. When the groove reaches the obstacle of the chain plate axle cable buckle on the cable, a hurdle-like notch is opened at the corresponding position of the support wheel. The depth of the notch matches the arc surface of the chain plate axle cable buckle, and the arc surface provides continuous support for the notch of the support wheel. Sprockets 20 are set on both sides of the cable support wheel corresponding to the two cable buckle chain rails 10. A transmission gear set is set inside the gearbox. The power of the gear system is driven by a reversible motor 7 located outside the self-operating gearbox 2, which drives the driving gear 21 to mesh with the transmission gear 22 and the driven gear 23 to form a linkage structure for the corresponding functional wheels. Inside the gearbox, on both sides corresponding to the lower part of the cable-stayed track 10, track limit wheels 28 are installed on the inner thread seat 33 of the optical shaft (which has the function of preventing the track wheel from derailing when running on steep slopes). The gearbox structure rod 29 is set in the middle of the gearbox by the structure rod seat 30 (which has the function of reinforcing the gearbox), and the whole constitutes the internal structure of various functional wheels of the single cable double chain track gearbox.

[0047] The single-cable double-chain cable rail 1 shown is in a taut state at both ends, that is, the cable rail is fixed in sections on the cable rail I-beam bridge 34 by the chain plate with axle cable buckle 11, and the combined slotted triangular frame 37 is connected to the upper end of the bridge frame pile 38 to form a single-cable double-chain cable rail overhead line pile column span support structure.

[0048] Figure 15-21The double-cable axle head buckle 1101 shown is adapted to the double-cable integrated slider 1602, and the axle head crossarm 39 is installed in an intermittent manner (effectively reducing the self-weight of the cable rail). The adapter component cable lower chain plate holding block 41 has integrated inner chain plates 14 at both ends. The combined chain shaft 42, chain shaft sleeve 19, and chain shaft roller 18 are fastened together with the two steel cables 9 to form a double-cable chain rail 1001 between the two steel cables. At the same time, the outer side of the two steel cables is limited by the chain plate limiting axle head 40 (semi-circular) on the integrated chain plate, and the inner side of the chain plate has a retaining spring axle head 43. The inner chain plate of the cable lower chain plate holding block is assembled and arranged by retaining spring 44 to form two limiting axle head chain rails 1002. The whole constitutes a double-cable three-chain cable rail 101 (heavy load type) structure. Then, the cable rail is installed on the cable rail I-beam bridge 34 using double cable shaft head buckles, and combined with the double cable triangular frame 3701 and connected to the upper end of the bridge frame pile 38 to form a double cable three-chain cable rail overhead line pile column span support structure.

[0049] The double-cable gearbox 201, located above the double-cable triple-chain cable rail 101, has two sets of corresponding functional wheels running longitudinally through both ends, connected by gear shafts 24. A sprocket 20 is positioned centrally on the double-cable chain rail 1001, a steel cable load wheel 31 is positioned on each of the two steel cables 9, and a chain rail limit wheel 28 is positioned below the limit shaft chain rail 1002 generated by the chain plate limit shaft head 40. Furthermore, a power gear set is located inside the double-cable gearbox; driven by a reversible motor 7 on the outside of the gearbox, the active gear 21 meshes with the transmission gear 22 and the driven gear 23. Its gear train linkage structure is identical to that of the self-operating gearbox 2, forming the functional wheel arrangement structure of the double-cable gearbox.

[0050] Figure 22-28 To further simplify the structure for use on flat terrain, the two steel cables 9 shown adopt a unified configuration of a double-cable hinged ring 1603 and a cross-shaped cap bolt 48, consisting of a through-shaft hinged cable buckle 1102 and a chain plate hinged cable buckle 1103 spaced apart. It also includes a through-shaft chain rail 1003 between the two steel cables, which is composed of an inner chain plate 14, a chain shaft sleeve 19, and a chain shaft roller 18 (containing a through shaft that replaces the chain shaft roller at intervals, which acts to enhance the connection strength of the two cables). In other words, it is integrated with the two steel cables to form a double-cable single-chain cable rail 102 (lightweight and simplified) structure mode with a single chain rail between the two steel cables. The cable rail is installed on the cable rail I-beam bridge 34 using a through-shaft fixing cable buckle 1104 adapter component cable buckle bow-shaped slider 1601, bolt 36, and bolt flat washer 50. The combined double cable triangular frame 3701 is connected to the upper end of the bridge frame pile 38, forming a double cable single chain cable rail line pile column span support structure. Inside the single chain gearbox 202 located above the double cable single chain cable rail, except for the omission of the limit wheel, the layout of all corresponding functional wheels and the linkage structure of the power gear set are the same as those of the double cable gearbox 201, forming the single chain gearbox functional wheel layout structure.

[0051] Figures 29-35 The track-changing boom 301 shown is equipped with a boom limiting plate 51 and a limiting boom sleeve 52 (to enhance load-bearing stability). The lower end of the track-changing boom is hooked to a snap-fit ​​hinge seat 401 located above the track-changing carbox 501. Two sets of hinge seats with hinge seat shaft heads 70 are respectively set on both sides of the hinge seat corresponding to the limiting plate boom sleeve 52. An electric push rod 59 is longitudinally set at the front between the two sets of seats, and is combined with the push rod horizontal shaft 60 and the buckle cover pull rod 58 set on both sides. This drives the buckle cover hinge shaft 71 on the upper part of the hinge seat to move the snap-fit ​​hinge cover 57 to enable it to open and close (for replacing the track-changing boom). When the hinge cover fastens the replaced track-changing boom, the two electric push rods 59 located at the rear outward edge of the snap-fit ​​hinge seat are inserted and locked by the push rod locking holes 69 opened on the edge of the snap-fit ​​hinge cover, completing the track-changing procedure of replacing the track-changing boom.

[0052] The upper part of the track-changing pile 3801 is equipped with a rocker arm ring slide rail 53 combined with a magnetically absorbing limiting rocker arm 54 with an electromagnetic chuck 55, and a rocker arm gear ring 56 driven to swing by the active gear 21 installed on the reversible motor 7 on the pile. This causes the electromagnetic chuck 55 on the limiting rocker arm to attach to the lifting rod limiting plate 51, forming a limiting and positioning function for the track-changing lifting box 501. After the lifting box is accurately positioned, the magnetic force of attraction is unlocked and disappears.

[0053] A lifting beam 62 is installed at the lower part between two transversely corresponding rail-changing piles 3801 within the rail-changing station shown. At each of the four corners of the beam are upper and lower lifting head 63, which insert into four sets of lifting head sleeves 64 installed on the rail-changing piles, forming a limiting structure for the lifting of the beam. Electric push rods 59 are installed on the rail-changing piles below both ends of the lifting beam as the power components for the beam's lifting. This constitutes the procedure for lowering the rail-changing carbox and replacing the rail-changing boom using the beam lifting mode.

[0054] The lifting beam 62 shown has longitudinally mounted slide rail groove platforms 76 on both sides. A changing track platform 65 is installed above the beam. Four short, movable hoisting box alignment plates 68 are erected along the four sides of the platform. The alignment plates are connected to electric push rods 59 located on the four sides below the changing track platform. The push rods drive the alignment plates to open outwards, creating an amplification effect on the four sides of the changing track platform. Before the changing track hoisting box is about to fall into place, the four sides of the hoisting box alignment plates retract inwards to correct the hoisting box base, ensuring precise placement. Below the changing track platform, along the longitudinal direction of the lifting beam, there is a lower platform structural plate 66 and a platform support plate 67. A structural groove is formed between the lower platform structural plate and the lifting beam. Four sets of pulley frames 72 are installed at the four corners of the upper changing track platform within the structural groove, mounting concave pulleys 73, which cooperate with the convex slide rails 75 mounted on the slide rail groove platform. The reversible motor 7 installed at the bottom of the platform structure plate is equipped with a drive gear 21 that meshes with a rack 77 in the groove below the slide rail slot. There are also four transmission gears 22 at the four corners that mesh with the rack (which act as limit wheels to enhance the stability of the track changing platform). This forms a structure in which the reversible motor drives the track changing platform to reciprocate laterally along the lifting beam, thus completing the track changing procedure of the hoisting box.

The aforementioned double-cable single-chain cable rail (102) consists of a through-shaft hinged cable buckle (1102) and spaced-apart chain plate hinged cable buckles (1103), a unified adapter component double-cable hinged ring (1603), a cross cap bolt (48), and is assembled between two steel cables (9) into a through-shaft chain rail (1003) composed of an inner chain plate (14), a chain shaft sleeve (19), and a chain shaft roller (18). It contains a through shaft that spaced out to replace the chain shaft roller, and its chain rail is fastened to the two steel cables as one unit, forming a double-cable single-chain cable rail (102) structure with one chain rail between the two steel cables. The mode adopts a through-shaft fixed cable buckle (1104) and a cable buckle bow slider (1601), bolt (36), bolt flat washer (50) to install its cable rail on the cable rail I-beam bridge (34). The combined double cable triangular frame (3701) is connected to the upper end of the bridge frame pile (38) to form a double cable single chain cable rail line pile column span support structure. The single chain gearbox (202) set above its cable rail has the same layout of all corresponding functional wheels and power gear group wheel system structure as the double cable gearbox (201) except that the limit wheel is omitted.

4. The self-operating and track-changing system for the overhead cableway gantry as described in claim 1, characterized in that... The snap-fit ​​hinge seat (401) is provided above the changing track hoist (501). The hinge seat is provided with two sets of hinge seats on both sides of the limiting plate hoist sleeve (52) of the changing track hoist (301). Electric push rods (59) are arranged longitudinally in front of the two sets of seats, and the push rod horizontal shaft (60) and the buckle cover pull rod (58) arranged on both sides are combined to drive the snap-fit ​​hinge cover (57) on the upper part of the hinge seat to complete the opening and closing. When the hinge cover fastens the changed track hoist, the two electric push rods (59) arranged at the rear outward edge of the snap-fit ​​hinge seat are inserted and locked in accordance with the push rod locking hole (69) opened on the edge of the snap-fit ​​hinge cover, thus completing the changing track hoist by replacing the changing track hoist.

5. The self-operating and track-changing system for the overhead cableway gantry as described in claim 1, characterized in that... The upper part of the variable track pile (3801) is provided with a magnetically pleasing limiting rocker arm (54) with an electromagnetic chuck (55), and combined with the rocker arm ring slide rail (53) and the rocker arm gear ring (56). The driving gear (21) installed on the reversible motor (7) on the pile engages with the rocker arm gear ring to drive the limiting rocker arm to swing in a ring, so that the electromagnetic chuck on the limiting rocker arm corresponds to the adsorption rod limiting plate (51) to form a limiting and positioning function for the variable track hoisting box (501). After the hoisting box is accurately positioned, the magnetic force of adsorption is unlocked and disappears.

6. The self-operating and track-changing system for the overhead cableway gantry as described in claim 1, characterized in that... A lifting beam (62) is installed at the lower part between two transversely corresponding rail-changing piles (3801) in the rail-changing station. The lifting beam has longitudinal sliding rail groove platforms (76) on both sides. Upper and lower lifting column heads (63) are provided at the four corners of both ends of the beam. The column heads are inserted into the four sets of lifting column head sleeves (64) installed on the rail-changing piles to form a limiting structure for lifting the beam. Electric push rods (59) are installed on the rail-changing piles corresponding to both ends of the lifting beam as the power components for lifting the beam. This constitutes the procedure of lowering the rail-changing gantry and replacing the rail-changing gantry rod in the mode of lifting the beam.

7. The self-operating and track-changing system for the overhead cableway gantry as described in claim 1, characterized in that... The aforementioned lifting beam (62) is equipped with a track-changing platform (65). Four short, movable hoisting box alignment plates (68) are erected along the four sides of the platform. The alignment plates are connected to electric push rods (59) set on the four sides below the track-changing platform. The push rods drive the alignment plates to open outwards on the four sides, forming an amplification effect on the four sides of the track-changing platform. Before the hoisting box is about to fall into place in response to the track-changing platform, the four sides of the hoisting box alignment plates retract inwards to correct the hoisting box base, so that it can be accurately positioned. The track-changing platform is equipped with an under-platform structural plate (66) and a platform support plate (67) along the longitudinal direction of the lifting beam. The structure groove is formed between the under-platform structure plate and the lifting beam. Four sets of pulley frames (72) are set at the four corners of the upper track-changing platform in the structure groove to install concave pulleys (73) and cooperate with the convex slide rails (75) set on the slide rail groove platform (76). The reversible motor (7) set at the lower part of the under-platform structure plate is equipped with a drive gear (21) that meshes with the rack (77) in the groove below the slide rail groove platform. The four transmission gears (22) at the four corners of the structure plate also mesh with the rack and have the function of limiting wheels, thus forming a structure in which the reversible motor drives the track-changing platform to move laterally back and forth along the lifting beam.
