Description

Technical Field

[0001] The present application belongs to the technical field of sky-rail transportation systems, and in particular, relates to a combination of a moving vehicle, a sky-rail freight train, and a sky-rail transportation system. Background Art

[0002] Bulk cargo such as mineral resources needs to be transferred from the yard or warehouse to the railway station and transported out by rail vehicles. At present, the basic cooperation in mineral resource mining is to transport the minerals from the mine to the train yard by container trucks, with poor road conditions and low efficiency. The altitude difference between the mine and the coal transportation railway station is large, and the maximum slope of ordinary railways is 20‰, so it is impossible to directly transport the mineral resources of the mine by rail transportation.

[0003] For this reason, an aerial rail transportation system has appeared on the market, which adopts a magnetic drive method. The magnetic drive linear motor has a large climbing performance, and the maximum climbing performance reaches 60‰ to 80‰. The aerial rail system adopts an aerial transportation method, which is not limited by terrain. The new aerial rail transportation system that combines the characteristics of the two is currently the most suitable way to solve the problems of large slopes, large drops, and mine transportation. For example, the invention application with publication number CN116394986A discloses an aerial rail transportation system suitable for mine freight.

DETAILED DESCRIPTION

[0048] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0049] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0050] In the field of rail transportation technology, the extension direction of the track is usually called "longitudinal", the horizontal direction perpendicular to the extension direction of the track is called "lateral", and the vertical direction is called "vertical", "vertical" or "height direction". The relevant expressions of the following directions: longitudinal, lateral, vertical, vertical and height directions, their specific interpretations can refer to the above definitions.

[0051] In a first aspect of the present application, a vehicle 1000 is provided, which is suitable for an air rail system 2000, that is, a bogie 100 of the vehicle 1000 can run along the track of the air rail system 2000. Figure 1 and Figure 8 The integrated transport vehicle 1000 includes a bogie 100, a suspension device 200, a car body 300 and a freight unit 400 connected in sequence. The upper part of the suspension device 200 is connected to the bogie 100, and the lower part is connected to the car body 300, and the freight unit 400 is connected to the lower side of the car body 300. The bogie 100 can run along the track of the sky rail system 2000, and the car body 300 and the freight unit 400 are driven to move together through the suspension device 200. The longitudinal dimension of the car body 300 is usually set to be not less than the longitudinal dimension of the freight unit 400, so as to be able to connect at least the four corners of the freight unit 400. Based on the large longitudinal dimension of the car body 300, the integrated transport vehicle 1000 is usually equipped with two bogies 100, and two suspension devices 200 are correspondingly set, and the two suspension devices 200 are respectively connected to the two ends of the car body 300.

[0052] Common bogies 100 include frame 110 type bogies 100 and three-piece type bogies 100. The specific structure of the bogie 100 is different according to the morphological structure of the track beam. For details, please refer to the relevant disclosure of the prior art, which will not be described in detail here. Figure 2 , shows a schematic structural diagram of a bogie 100 suitable for a box-type track beam 2100 in some embodiments, wherein the bogie 100 is located inside the box-type track beam 2100, and the lower part of the box-type track beam 2100 is open for the lower end of the suspension device 200 to extend out. The main body of the bogie 100 is a frame 110, on which two sets of running wheels 120 and two sets of guide wheels 130 are mounted. According to the specific arrangement position of the track in the box-type track beam 2100, the running wheels 120 and the guide wheels 130 on the same side may be parallel and coplanar, parallel but not coplanar, or arranged at an angle. Figure 2 In the illustrated embodiment, the traveling wheel 120 and the guide wheel 130 are parallel and coplanar, and the height of the guide wheel 130 is greater than the height of the traveling wheel 120 .

[0053] See also Figure 2In some embodiments, the bogie 100 further includes a tread brake 150, which is mounted on the frame 110 and close to the running wheel 120. The tread brake 150 acts on the running wheel 120 to decelerate the moving vehicle 1000 (gravity downhill process) or decelerate to stop (stop at the station or stop to avoid a faulty vehicle in front).

[0054] The suspension device 200 is connected to the center of the bogie 100. For the frame 110 type bogie 100, the frame 110 is a symmetrical structure as a whole, and the corresponding suspension device 200 is connected to the center of the frame 110. The specific connection structure of the suspension device 200 and the bogie 100 can refer to the relevant disclosure of the prior art, such as the "Suspension Mechanism for Container Transfer" with publication number CN109466564A.

[0055] See also Figure 3 , shows an assembly structure diagram of the suspension device 200, the bogie 100 and the car body 300 in some embodiments. The main body of the suspension device 200 is the traction center pin 210, and the top end of the traction center pin 210 is connected to the bogie 100 through an elastic member 220. The elastic member 220 can be a rubber spring, such as a secondary rubber spring. The rubber spring is installed in the main body of the bogie 100, so that the traction center pin 210 and the bogie 100 are in flexible contact through the rubber, and there is no rigid contact between the two.

[0056] See also Figure 3 and Figure 4 In some embodiments, the suspension device 200 includes an anti-slip seat 240, which is fixedly mounted on the traction center pin 210 and is located below the connection between the bogie 100 and the suspension device 200. The function of the anti-slip seat 240 is to prevent the car body 300 from driving the suspension device 200 upward when the bogie 100 is in emergency braking or braking, thereby preventing the connection structure between the suspension device 200 and the bogie 100 from being vertically impacted. The anti-slip seat 240 is provided to improve the safety of the connection between the suspension device 200 and the bogie 100.

[0057] See also Figure 2 , Figure 3 and Figure 4In some embodiments, the bogie 100 is provided with a limit seat 111, and at least part of the elastic member 220 is located in the limit seat 111. The limit seat 111 may be a circular groove, and the bottom end of the elastic member 220 is located in the circular groove and abuts against the groove wall. The specific position of the anti-slip seat 240 on the traction center pin 210 should meet the following requirements: the spacing between the anti-slip seat 240 and the bottom surface of the bogie 100 is not greater than the vertical limit amount of the elastic member 220 and the limit seat 111, and the vertical limit amount of the elastic member 220 and the limit seat 111 refers to the vertical displacement required for the elastic member 220 to detach from the limit seat 111. That is to say, the distance between the anti-slip seat 240 and the bottom surface of the bogie 100 is less than or equal to the vertical displacement required for the elastic member 220 to disengage from the limiting seat 111. Even if the car body 300 drives the suspension device 200 to push up, the suspension device 200 can only move upward to the position where the anti-slip seat 240 abuts the bottom surface of the bogie 100. At this time, the upward displacement of the suspension device 200 is not enough to make the elastic member 220 disengage from the limiting seat 111, thereby achieving the technical effect of preventing the bogie 100 from being disconnected from the suspension device 200.

[0058] See also Figure 3 and Figure 4 In some embodiments, the suspension device 200 includes a traction ball joint 260, which includes an inner sleeve, an outer sleeve, and an elastic layer disposed between the inner sleeve and the outer sleeve. The outer sleeve is interference-fitted with the bogie 100; the inner sleeve is nested inside the outer sleeve and sleeved on the outer periphery of the traction center pin 210, and the elastic layer between the inner sleeve and the outer sleeve further realizes the flexible contact between the traction center pin 210 and the bogie 100, and improves the connection stability between the traction center pin 210 and the bogie 100. Since the traction ball joint 260 is connected to the bogie 100, the traction ball joint 260 is disposed above the anti-slip seat 240.

[0059] The lower part of the suspension device 200 is connected to the vehicle body 300, see Figure 3 and Figure 4 The bottom end of the traction center pin 210 is provided with a longitudinal connecting pin 250, and the traction center pin 210 is hinged to the vehicle body 300 through the longitudinal connecting pin 250. The axis of the longitudinal connecting pin 250 extends in the longitudinal direction, allowing the vehicle body 300 to swing in the lateral direction relative to the empty rail system 2000. In the height direction, the pin shaft is hinged to the middle part of the frame 310 of the vehicle body 300.

[0060] See also Figure 3 , Figure 4 and Figure 5A transverse stop unit 10 and a longitudinal stop unit 20 are provided at the connection between the vehicle body 300 and the suspension device 200. The transverse stop unit 10 includes at least two transverse stop seats 11, which are distributed on both sides of the suspension device 200 along the transverse direction of the vehicle body 300. The transverse stop seats 11 can be installed on the vehicle body 300 and / or the suspension device 200. For example, in some embodiments, both transverse stop seats 11 are installed on the vehicle body 300, such as Figure 4 As shown; in other embodiments, the two transverse stoppers 11 can be installed on the suspension device 200. In other embodiments, the two transverse stoppers 11 can also be installed on the vehicle body 300 and the suspension device 200 respectively. By providing the transverse stoppers 11 distributed on both sides of the suspension device 200, the lateral swing of the vehicle body 300 and the freight unit 400 as a whole can be limited, and the lateral impact can be absorbed to prevent the vehicle body 300 and the freight unit 400 from swinging in strong winds and colliding with the air rail system 2000.

[0061] like Figure 4 As shown, in some embodiments, a transverse shock absorber 30 is provided at the connection between the car body 300 and the suspension device 200, one end of the transverse shock absorber 30 is connected to the car body 300, and the other end is connected to the suspension device 200, and the car body 300, the suspension device 200 and the transverse shock absorber 30 form a triangular shock absorbing area. When the car body 300 and the freight unit 400 sway laterally due to external force (such as wind), the car body 300 squeezes the transverse shock absorber 30 on one side of the swing direction, and the transverse shock absorber 30 on the other side is stretched, and both transverse shock absorbers 30 generate a restoring force to drive the car body 300 and the freight unit 400 to restore the normal posture. The elasticity of the transverse shock absorber 30 itself can also absorb part of the transverse side swing force, reducing the amplitude of the transverse side swing of the car body 300 and the freight unit 400.

[0062] The longitudinal stop unit 20 includes at least two longitudinal stop seats 21, which are spaced apart and distributed on both sides of the suspension device 200 along the longitudinal direction of the vehicle body 300. The longitudinal stop seats 21 can be installed on the vehicle body 300 and / or the suspension device 200. For example, in some embodiments, the two longitudinal stop seats 21 are both installed on the vehicle body 300, such as Figure 3 and Figure 5 As shown; in other embodiments, the two longitudinal stop seats 21 can be installed on the suspension device 200. In other embodiments, the two longitudinal stop seats 21 can also be installed on the vehicle body 300 and the suspension device 200 respectively. By providing the longitudinal stop seats 21 distributed on both sides of the suspension device 200, the longitudinal swing of the vehicle body 300 and the freight unit 400 as a whole can be limited, and the longitudinal impact can be absorbed. When braking and running on a large slope, the connection between the suspension device 200 and the vehicle body 300 is protected from shear force, making the suspension device 200 safer.

[0063] See also Figure 3 , Figure 4 and Figure 5 In some embodiments, the transverse stop unit 10 further includes two transverse stop portions 12 disposed on both sides of the suspension device 200 along the transverse direction of the vehicle body 300, and the transverse stop portions 12 correspond to the transverse stop seats 11 on the same side. The transverse stop portions 12 can be installed on the vehicle body 300 and / or the suspension device 200. For example, in some embodiments, both transverse stop portions 12 are installed on the suspension device 200. Figure 4 As shown; in other embodiments, the two transverse stoppers 12 can be both installed on the vehicle body 300. In other embodiments, the two transverse stoppers 12 can also be installed on the vehicle body 300 and the suspension device 200 respectively. No matter where the transverse stopper 12 and the transverse stopper seat 11 are installed, it is necessary to ensure that one of the transverse stopper 12 and the transverse stopper seat 11 corresponding in position is installed on the vehicle body 300, and the other is installed on the suspension device 200, and there is a transverse interval between the transverse stopper 12 and the corresponding transverse stopper seat 11. At least one of the transverse stopper 12 and the transverse stopper seat 11 is provided with an elastic block, such as a rubber block. The elastic block can absorb lateral impact to a certain extent.

[0064] like Figure 4 As shown, in some embodiments where a lateral shock absorber 30 is provided at the connection between the vehicle body 300 and the suspension device 200, the size of the lateral interval should allow the lateral shock absorber 30 on the same side to be effectively compressed when the lateral stopper 12 at the corresponding position contacts the lateral stopper seat 11. In some embodiments, the lateral interval is configured to allow the swing angle of the vehicle body 300 relative to the empty rail system 2000 to not exceed 10°, that is, when the lateral stopper 12 contacts the lateral stopper seat 11, the swing angle of the vehicle body 300 relative to the empty rail system 2000 is ≤10°, such as 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, etc. In some embodiments, the lateral interval is 50-100 mm, such as 55 mm, 60 mm, 63 mm, 68 mm, 70 mm, 75 mm, 78 mm, 85 mm, 92 mm, 95 mm, 97 mm, etc.

[0065] See also Figure 3 , Figure 4 and Figure 5 In some embodiments, the longitudinal stop unit 20 further includes two longitudinal stop portions 22 disposed on both sides of the suspension device 200 along the longitudinal direction of the vehicle body 300, and the longitudinal stop portions 22 correspond to the longitudinal stop seats 21 on the same side. The longitudinal stop portions 22 can be installed on the vehicle body 300 and / or the suspension device 200. For example, in some embodiments, both longitudinal stop portions 22 are installed on the suspension device 200, such as Figure 3As shown; in other embodiments, the two longitudinal stoppers 22 can be both installed on the vehicle body 300. In other embodiments, the two longitudinal stoppers 22 can also be installed on the vehicle body 300 and the suspension device 200 respectively. No matter where the longitudinal stoppers 22 and the longitudinal stopper seat 21 are installed, it is necessary to ensure that one of the longitudinal stoppers 22 and the longitudinal stopper seat 21 corresponding in position is installed on the vehicle body 300, and the other is installed on the suspension device 200, and there is a longitudinal interval between the longitudinal stoppers 22 and the corresponding longitudinal stopper seat 21. At least one of the longitudinal stoppers 22 and the longitudinal stopper seat 21 is provided with an elastic block, such as a rubber block. The elastic block can absorb longitudinal impact to a certain extent.

[0066] Since the longitudinal swing may generate harmful shear force on the suspension device 200, it is necessary to limit the longitudinal swing, and the longitudinal interval between the corresponding longitudinal stop portion 22 and the corresponding longitudinal stop seat 21 is smaller than the transverse interval between the transverse stop portion 12 and the corresponding transverse stop seat 11. In some embodiments, the longitudinal interval is 3 to 20 mm, such as 3 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, etc. In some embodiments, the longitudinal interval is 5 to 15 mm, such as 5.5 mm, 6 mm, 6.3 mm, 7 mm, 7.5 mm, 8.5 mm, 9.5 mm, 10 mm, 10.5 mm, 11.5 mm, 12.5 mm, 13.5 mm, 14.5 mm, etc.

[0067] See also Figure 3 and Figure 4 In some embodiments, the suspension device 200 is provided with a stop center seat 230, which is mounted on the traction center pin 210 and is located above the vehicle body 300. The transverse stop portion 12 and the longitudinal stop portion 22 are both disposed on the stop center seat 230, and the transverse stop seat 11 and the longitudinal stop seat 21 are both mounted on the vehicle body 300. Both ends of the transverse shock absorber 30 are connected to the vehicle body 300 and the stop center seat 230, respectively.

[0068] See also Figure 5 In some embodiments, the transverse stopper 11 and the longitudinal stopper 21 are both installed on the upper side of the vehicle body 300. To avoid interference between the transverse stopper 10 and the longitudinal stopper 20, in some embodiments, the transverse stopper 10 and the longitudinal stopper 20 have a height difference. Figure 3 and Figure 4In some embodiments, the transverse stopper 11 is located in the area surrounded by the vehicle body 300, the suspension device 200 and the transverse shock absorber 30. The area has sufficient space, which is convenient for arranging the transverse stopper 11, and the transverse stopper 11 will not interfere with the extension and contraction of the transverse shock absorber 30. The position of the transverse stopper 11 is lower than the connection between the transverse shock absorber 30 and the suspension device 200, and the position of the longitudinal stopper 21 is higher than the transverse shock absorber 30. Correspondingly, the position of the longitudinal stopper 21 is also higher than the transverse stopper 11, thereby making the height difference between the longitudinal stopper 21 and the longitudinal connecting pin 250 larger. When the collective sports vehicle 1000 is braked in an emergency, the longitudinal stopper 21 and the longitudinal stop portion 22 can quickly abut against each other to resist the longitudinal impact. In some embodiments, the height difference between the bottom surface of the longitudinal stop seat 21 and the frame 310 of the vehicle body 300 is 200-300 mm, such as 210 mm, 230 mm, 250 mm, 260 mm, 275 mm, 280 mm, 290 mm, 295 mm, etc.

[0069] See also Figure 5 and Figure 6 , shows a schematic diagram of the structure of the vehicle body 300 in some embodiments, and an assembly diagram of the vehicle body 300 and the freight unit 400. The main body of the vehicle body 300 is a frame 310, and the frame 310 can adopt a fishbone beam structure or a frame structure. In some embodiments, the frame 310 is a fishbone beam structure, which is lighter than the frame beam structure, and is conducive to lightweighting of the entire vehicle.

[0070] like Figure 6 As shown, the fishbone beam structure includes a long longitudinal beam located in the middle and a plurality of cross beams cross-connected with the long longitudinal beam. The long longitudinal beam is the main beam 311, and the plurality of cross beams include a bolster 312 and a support beam 313. The main beam 311 and the bolster 312 are relatively high, and the bolster 312 and the main beam 311 divide the upper space of the frame 310 into a plurality of areas. There are a large number of support beams 313, which are arranged at the bottom of the area. The suspension device 200 is connected to the intersection of the main beam 311 and the bolster 312, where the structural strength is the greatest. Two protruding ribs are arranged on the main beam 311 near the suspension device 200, for mounting the longitudinal stop seat 21. The transverse stop seat 11 is mounted on the bolster 312.

[0071] The connection between the vehicle body 300 and the freight unit 400 may be a hanging fixing method or a lifting fixing method, which is not limited in this application. Figure 5As shown, in some embodiments, the vehicle body 300 is provided with a hook arm beam 320, and the hook arm beam 320 is connected to the lower side of the vehicle frame 310. The freight unit 400 is connected to the hook arm beam 320, and the bottom end of the freight unit 400 extends out of the area surrounded by the hook arm beam 320, that is, the hook arm beam 320 does not affect the bottom operation of the freight unit 400. For example, when the freight unit 400 is a hopper box, the bottom end of the hopper box extends out of the area surrounded by the hook arm beam 320, and does not affect the opening and closing of the hopper bottom door. Compared with the hanging fixing method, the lifting fixing method is safer and more suitable for long-distance transportation, and can withstand the harsh environment of large wind volume and heavy sand.

[0072] like Figure 5 As shown, in some embodiments, the hook arm beam 320 is L-shaped as a whole, including a column and a hook portion 321. A first locking portion 322 is provided on the upper side of the hook portion 321 of the hook arm beam 320, and a second locking portion is provided on the upper portion of the freight unit 400. The upper portion of the freight unit 400 is placed on the hook portion 321, and the first locking portion 322 is locked with the second locking portion. The specific structure of the first locking portion 322 and the second locking portion can refer to the existing container locks. For example, the first locking portion 322 is a rotary lock device, and the second locking portion is a corner piece. The rotary lock device and the corner piece are mature technologies in the container field, and the specific contents are not elaborated here. The second locking portion can be arranged on the freight unit 400, or a convex portion 410 can be provided at the corner of the freight unit 400, and the second locking portion can be arranged on the convex portion 410, as shown in FIG. Figure 5 shown.

[0073] The freight unit 400 may be a flat-bottom box or a hopper box. The flat-bottom box may be a container, an ordinary open cargo box, etc. The hopper box may be a hopper container, a hopper structure, etc. In some embodiments, the freight unit 400 is an open cargo box such as an ordinary open cargo box or a hopper box. The vehicle body 300 is provided with a top cover assembly (not shown in the figure). The top cover assembly includes a top cover and one or more lifting mechanisms for driving the top cover to rise and fall. The lifting mechanism is fixedly mounted on the vehicle frame 310, and its output end is connected to the top cover. The top cover is raised before the box is changed, which does not affect the box change operation. After the box is changed, the top cover is lowered and pressed directly above the cargo box to cover the upper opening, which can prevent dust pollution caused by strong winds during transportation and prevent the risk of fire caused by combustibles such as coal powder.

[0074] like Figure 5 As shown, in some embodiments, the four corners of the top of the freight unit 400 are provided with a convex portion 410, and the convex portion 410 is provided with a second locking portion. The freight unit 400 is connected to the vehicle body 300 by the convex portion 410 being placed on the hook portion 321, and the first locking portion 322 is locked with the second locking portion. Since the hook arm beam 320 is connected to the top of the freight unit 400, compared with the conventional bottom-supporting fixing method, the height dimension of the hook arm beam 320 is smaller, which is conducive to lightweighting of the entire vehicle.

[0075] like Figure 5 As shown, in some embodiments, a diagonal brace 330 is provided on the vehicle body 300 to strengthen the hook arm beam 320. The two ends of the diagonal brace 330 are respectively connected to the frame 310 and the hook arm beam 320. Since the hook arm beam 320 is connected to the top of the freight unit 400, the length of the corresponding diagonal brace 330 is also shorter. The angle between the diagonal brace 330 and the frame 310 is generally 30° to 60°. As the length of the hook arm beam 320 increases, the length of the diagonal brace 330 increases accordingly. The principle is similar to that in similar right triangles, the longer the right angle side, the longer the hypotenuse side. On the one hand, shortening the length of the diagonal brace 330 is beneficial to weight reduction. More importantly, the connection between the diagonal brace 330 and the frame 310 is closer to the hook arm beam 320 and will not occupy the lower space on both sides of the frame 310, making it convenient to install electrical equipment here. Figure 5 As shown, in some embodiments, the connection between the diagonal brace 330 and the frame 310 is located below one of the bolsters 312. The connection between the bolster 312 and the main beam 311 is used to connect the suspension device 200. The diagonal brace 330 is connected to the bolster 312, and the connection strength is high.

[0076] like Figure 7 As shown, in some embodiments, the collective vehicle 1000 also includes an electrical and control system 500, which is mainly used to provide power and control signals for the travel and braking of the bogie 100, and to provide power and control signals for other low-voltage electrical devices on the collective vehicle 1000 (such as a speed sensor for detecting the travel speed of the collective vehicle 1000, an electronic tag for recording the identity information of the collective vehicle 1000, and a vehicle-mounted loop antenna for data exchange with a central device, etc.). The specific content of the electrical and control system 500 is not limited in this application.

[0077] The electrical and control system 500 is installed on the car body 300, and can be installed on the upper side and the lower side of the car body 300, making full use of the space on the upper side of the car body 300. For example, in some embodiments, each electrical device in the electrical and control system 500 can be installed in the upper space of the frame 310 and the lower space on both sides of the frame 310. As a result, the length of the car body 300 can be shortened. Taking the collective vehicle 1000 with a rated load of 32t (tons), a maximum operating speed of 50Km / h, a minimum curve radius of 50m, and a climbing ability of 75‰ as an example, the total length of the car body 300 can be shortened to within 13.4m, and the center distance between the two bogies 100 / suspension devices 200 can be shortened to within 8.8m.

[0078] like Figure 7As shown, in some embodiments, the electrical and control system 500 includes at least a traction inverter 510, a high-voltage control box 520, an electrical control box 530 and a wind brake assembly 540. The traction inverter 510 is electrically connected to the high-voltage control box 520 to supply power to the drive motor of the bogie 100, and the electrical control box 530 is used to control the low-voltage electrical components on the collective motion vehicle 1000, and to realize signal transmission and communication functions. The wind brake assembly 540 is used to provide power to the tread brake 150 of the collective motion vehicle 1000. Among the above-mentioned accessories, the traction inverter 510 has the largest volume and can be arranged at both ends of the lower side of the frame 310, that is, the area outside the diagonal brace 330. The high-voltage control box 520, the electrical control box 530 and the wind brake assembly 540 are all installed on the upper side of the frame 310, distributed in several areas separated by the bolster 312 and the main beam 311 of the frame 310, and connected to the support beam 313 of the frame 310.

[0079] The number of traction inverters 510 is the same as the number of bogies 100. Figure 7 As shown, in some embodiments, two traction inverters 510 are provided, and the two traction inverters 510 are distributed at both ends of the vehicle body 300 in the longitudinal direction, and are both located on the lower side of the vehicle body 300. The high-voltage control box 520 is installed on the upper side of the vehicle body 300 and is located above one of the traction inverters 510. The high-voltage control box 520 is electrically connected to the traction inverter 510 located below it through a high-voltage cable 570, which is used to connect the high-voltage electricity in the high-voltage grid to the traction inverter 510. The high-voltage control box 520 is close to the traction inverter 510, which can shorten the length of the high-voltage cable 570.

[0080] In some embodiments, a slideway (not shown) can be welded on the lower side of the vehicle frame 310, and the traction inverter 510 is slidably embedded in the slideway and fixed in position, which makes it easy to disassemble and assemble the traction inverter 510. Since the traction inverter 510 has high power (converts 600V voltage to 380V voltage) and high electromagnetic radiation, the traction inverter 510 is arranged at both ends of the vehicle body 300 in the longitudinal direction, which can avoid interference with the low-voltage electrical components in the middle of the vehicle body 300.

[0081] like Figure 7 As shown, in some embodiments, the air brake assembly 540 includes an air compressor 541 and a brake air cylinder 542 connected through an air duct, and the air compressor 541 is installed on the upper side of the vehicle body 300 and is located above another traction inverter 510. The air compressor 541 uses a 380V voltage and is relatively less affected by the traction inverter 510. In order to reduce the length of the air duct, as shown in FIG. Figure 7 As shown, in some embodiments, the air compressor 541 and the brake cylinder 542 are arranged on the same side of the frame 310 .

[0082] like Figure 7 As shown, in some embodiments, the electrical and control system 500 also includes an on-board backup power supply 550 and an auxiliary transformer box 560. The electrical control box 530, the on-board backup power supply 550 and the auxiliary transformer box 560 are all installed on the upper side of the vehicle body 300, and are located between the two traction inverters 510 in the longitudinal direction. The electrical control box 530, the on-board backup power supply 550 and the auxiliary transformer box 560 use a 220V voltage and are far away from the traction inverter 510 to reduce the impact of electromagnetic radiation. The output voltage of the on-board backup power supply 550 is 110V, which is used to supply power to some low-voltage electrical devices to ensure that the signal of the on-board system on the integrated sports car 1000 is not interrupted.

[0083] In some embodiments, the bogie 100 is driven by a linear motor 800. Fig.13 As shown, the top of the bogie 100 is provided with a mover 810 of a linear motor 800, and the mover 810 is coupled with a stator 820 of the linear motor 800 provided on the track beam of the empty rail system 2000. There is a gap of about 10 mm between the mover 810 and the stator 820 of the linear motor 800. The mover 810 cooperates with the stator 820 to provide traction for the bogie 100 to move. The high-voltage control box 520 is electrically connected to the traction inverter 510, and the traction inverter 510 converts the input high-voltage electricity into a 380V working voltage of the linear motor 800, and then the traction inverter 510 supplies the coil of the mover 810 of the linear motor 800. At the same time, the traction inverter 510 is also a switch for powering the linear motor 800, and can also control the size and direction of the output current, change the size of the electromagnetic force of the linear motor 800, and change the direction of the electromagnetic force, which can be divided into the driving force for forward movement and the electric braking force for braking.

[0084] See also Fig.13 In some embodiments, a current collector 140 is provided on the bogie 100. The current collector 140 uses sliding contact to obtain electricity and contacts the power supply rail 2130 on the track beam of the empty rail system 2000. The power supply rail 2130 is connected to the traction power supply system. The current collector 140 is connected to the high-voltage control box 520 to supply power to the electrical components on the collective motion vehicle 1000. In some embodiments, a tread brake 150 is provided on the bogie 100 for deceleration and braking when going downhill. The tread brake 150 provides driving power through the wind brake assembly 540.

[0085] See also Figure 8, shows a schematic diagram of the structure of the multi-purpose vehicle 1000 in other embodiments. The multi-purpose vehicle 1000 is provided with a coupler 600 and / or a traction rod 700, and the coupler 600 and the traction rod 700 are both located at the ends of the vehicle body 300. The specific structure of the coupler 600 can adopt the coupler 600 buffer device of the railway vehicle, and the specific content is not described in detail here. If a multi-purpose vehicle 1000 in operation fails, the coupler 600 and / or the traction rod 700 can be used to connect the faulty multi-purpose vehicle 1000 to a rescue vehicle, and the rescue vehicle transfers the faulty multi-purpose vehicle 1000 to the fault stop line of the air rail system 2000 to avoid affecting the operation of subsequent vehicles. The coupler 600 can be manually connected, automatically connected and manually unlocked, which is convenient for operation. The traction rod 700 needs to be connected and unlocked with the help of special tools, so the connection is more stable. According to the actual needs of the collective vehicle 1000, for example, when the collective vehicle 1000 is in formation operation, the couplers 600 or the traction rods 700 can be installed at both ends of the vehicle body 300 according to the position of the collective vehicle 1000 in the formation.

[0086] In summary, the integrated sports vehicle 1000 provided by the present application has the following advantages:

[0087] 1) The integrated motion vehicle 1000 provided in the embodiment of the present application is developed and designed by using magnetic drive technology in combination with the existing standard sky rail system 2000. The integrated motion vehicle 1000 adopts a magnetic drive linear motor 800 as a power source, which can achieve climbing of a larger slope. The track beam of the sky rail integrated motion vehicle 1000 continues to use the conventional box-type track beam 2100. The box-type track beam 2100 structure can be used in conjunction with the installation characteristics of the linear motor 800 to integrate the non-powered bogie 100 structure and the linear motor 800 to form a powered bogie 100 driven by the linear motor 800. The central large pin suspension device 200 of the upper bolster connects the bogie 100 and the frame 310 to form the main structure of the whole vehicle. The frame 310 has a short rigid hook arm beam 320, a special freight unit 400 for transporting coal, and a fast box filling and changing operation equipment (reference patent CN116675023A), which can realize the fast loading and unloading and box changing operations of the freight unit 400.

[0088] 3) The transport vehicle 1000 provided in the embodiment of the present application is provided with a transverse stop unit 10, so that in the case of strong winds, when the frame 310 swings to the point where the transverse stop seat 11 contacts the transverse stop portion 12 of the suspension device 200, the frame 310 and the suspension device 200 will not continue to swing relative to each other, and the suspension device 200, the vehicle body 300 and the freight unit 400 can be regarded as a whole. The wind load will cause the whole to swing together, and at this time, the swing point is located at the position where the traction ball joint 260 and the elastic member 220 of the suspension device 200 are located. The center of gravity of the whole formed by the suspension device 200, the vehicle body 300 and the freight unit 400 is relatively low, the distance from the center of gravity to the swing point is far, and the swing angle is small, thereby achieving the technical effect of reducing the lateral swing amplitude of the vehicle body 300 and the freight unit 400 in strong winds. In addition, since the distance from the center of gravity of the whole formed by the suspension device 200, the car body 300 and the freight unit 400 to the swing point is far, the lateral force of the wind load on the car body 300 transmitted to the frame 110 of the bogie 100 (the lateral force transmitted to the bogie 100 by the traction ball joint 260 of the suspension device 200) will be smaller, reducing the probability of the bogie 100 tilting or derailing.

[0089] 3) The integrated vehicle 1000 provided in the embodiment of the present application, when the integrated vehicle 1000 is subjected to emergency braking, the vehicle body 300 and the freight unit 400 will have a tendency to continue to move due to inertia. The presence of the longitudinal stop unit 20 can make the longitudinal swing range of the vehicle body 300 and the suspension device 200 very small, and can avoid the damage of the longitudinal connecting pin 250 and the traction ball joint 260 by the braking impact. When running on a large slope, the presence of the longitudinal stop unit 20 can ensure that the frame 310 is always perpendicular to the traction center pin 210, and the frame 310 is parallel to the track of the air rail system 2000, reducing the shearing effect on the longitudinal connecting pin 250 of the suspension device 200, and the safety of the suspension device 200 is higher. When the couplers 600 of the two vehicles are docked, the impact directly acts on the frame 310, and the longitudinal stop can absorb most of the impact on the suspension device 200 and the bogie 100, protecting the bogie 100 and the linear motor 800.

[0090] 4) The vehicle 1000 provided in the embodiment of the present application has a vehicle coupler 600 and / or a traction rod 700 at the head and tail of the vehicle body 300, which can be conveniently formed into a group, and can form a transportation mode of multiple groups. The single transportation volume is much larger than the traditional automobile transportation volume. Through the circular two-way empty rail line, a circular reciprocating transportation mode can be formed, which greatly improves the transportation efficiency. And it is convenient for rescue vehicles to rescue in case of failure.

[0091] 5) The transport vehicle 1000 provided in the embodiment of the present application has a frame 310 with a short rigid hook arm beam 320, which does not interfere with the bottom operation of the freight unit 400. The freight unit 400 can be replaced according to actual transportation needs. When transporting lump coal, a flat bottom box can be directly used and directly converted to automobile or rail transportation at the unloading point; when transporting fine coal, a hopper box is used to transport it to the unloading point, and then a quick loading operation is performed to change to rail transportation. The two transportation schemes of flat bottom box and hopper box are easy to switch.

[0092] 6) The electric equipment of the electric and control system 500 of the integrated sports vehicle 1000 provided in the embodiment of the present application is distributed on the upper and lower sides of the frame 310, making full use of the installation space of the frame 310. The use of a shorter hook arm beam 320 effectively reduces the occupied space, thereby increasing the installation space of the frame 310. The frame 310 has a more compact structure and the length can be shortened to less than 13.4m.

[0093] 7) The traveling wheels and positioning wheels of the bogie 100 of the integrated vehicle 1000 provided in the embodiment of the present application are both made of steel wheels and steel rails, which have lower traveling resistance than rubber wheels and longer service life. The hinge point between the vehicle body 300 and the suspension device 200 has a large height difference from the center of gravity, which can reduce the yaw angle of the vehicle body 300 when unloaded, which is helpful for resisting strong winds.

[0094] 8) The transport vehicle 1000 provided in the embodiment of the present application is equipped with a lifting type box top cover device on the frame 310. The top cover is raised before the box is changed without affecting the box changing operation. After the box is changed, the top cover is lowered and pressed directly above the box, which can prevent dust pollution caused by strong winds during transportation and prevent the risk of fire caused by coal powder.

[0095] See also Fig. 9 According to the second embodiment of the present application, there is provided an aerial rail freight marshaling 1100, comprising at least two transport vehicles 1000 of any one of the first embodiments. Each transport vehicle 1000 is connected end to end to form a transport mode of multiple marshalings. The single transport volume is much larger than the traditional automobile transport volume. Through the circular bidirectional aerial rail line, a cyclical transport mode can be formed, which greatly improves the transport efficiency. And when the marshaling is running, when the failure rate of the transport vehicle 1000 is within 50%, the aerial rail freight marshaling 1100 can run smoothly, greatly improving the freight efficiency.

[0096] When the transport vehicles 1000 are in formation and running, the main structure of each transport vehicle 1000 is the same, and the accessories carried (different types of freight units 400, electrical and control systems 500, couplers 600, traction rods 700, etc.) may be slightly different. For example, depending on the location of the transport vehicle 1000, the connection between the coupler 600 or the traction rod 700 at both ends of the vehicle body 300 is different. Or depending on the location of the transport vehicle 1000, the type of electrical equipment included in the electrical and control system 500 is different. The following will combine Fig. 9 and Fig.10 Provide explanation.

[0097] See also Fig. 9 In some embodiments, two adjacent collective vehicles 1000 are connected by a traction rod 700, and the outer ends of the collective vehicles 1000 at both ends are provided with a hook 600. In other words, the outer ends of the collective vehicles 1000 at both ends are provided with a hook 600, and the inner ends are provided with a traction rod 700, and the two ends of the collective vehicle 1000 located in the middle are provided with a traction rod 700.

[0098] In some embodiments, the integrated vehicle 1000 further includes a high-voltage control box 520, an electrical control box 530, and two traction inverters 510 distributed at both longitudinal ends of the vehicle body 300, wherein the high-voltage control box 520 is close to one of the traction inverters 510, and the longitudinal position of the electrical control box 530 is located between the two traction inverters 510.

[0099] like Fig.10 As shown, in some embodiments, in at least one of the train cars 1000 of the sky rail freight train 1100, the high-voltage control box 520 is electrically connected to the adjacent traction inverter 510 and the traction inverter 510 of the adjacent train car 1000. This makes the length of the high-voltage cable 570 the shortest, and does not cause the high-voltage cable 570 to cross the entire car body 300 in the longitudinal direction, which facilitates wiring.

[0100] Combine the following Fig.10 The high voltage design of the sky rail freight train 1100 in some embodiments is described. For the convenience of description, the forward direction of the train 1000 is forward, and the reverse direction is backward. The train 1000 located at the front is referred to as the head train, and the train 1000 located at the rear is referred to as the tail train. The traction inverter at the front is denoted as 510a, and the traction inverter at the rear is denoted as 510b. For example, the high voltage control box 520 is located above the traction inverter 510b. Fig.10The high-voltage control box 520 of the leading vehicle is provided with three high-voltage branches, which are respectively connected to the traction inverter 510a and the traction inverter 510b of the same vehicle, and the traction inverter 510a of the rear vehicle through the high-voltage cable 570, that is, the high-voltage control box 520 of the leading vehicle will be routed from the middle of the vehicle body 300. The intermediate collection vehicle 1000 adopts the high-voltage control box 520 to supply power to the traction inverter 510b of the same vehicle and the traction inverter 510a of the rear vehicle, and no high-voltage cable 570 is arranged in the middle of the vehicle body 300 of the intermediate collection vehicle 1000 and the rear vehicle.

[0101] Since the high-voltage control box 520 of the lead car will be routed through the middle of the car body 300, in order to avoid signal interference, the electrical control box 530 of the lead car does not have a signal system, but only an electrical control system. The electrical control box 530 of the middle train 1000 is equipped with both a signal system and an electrical control system, which is equivalent to the control system and signal system for monitoring the operation of the vehicle of the sky rail freight marshaling 1100 being arranged on the middle car.

[0102] It is understandable that Fig.10 If the front and rear directions of the aerial rail freight marshaling 1100 are reversed, the high-voltage cables 570 are not arranged in the middle of the car body 300 of the leading car and the middle collective car 1000, and the high-voltage control box 520 of the rear car will be routed from the middle of the car body 300. Accordingly, the electrical control box 530 of the rear car does not have a signal system, but only an electrical control system. The electrical control box 530 of the middle collective car 1000 is equipped with both a signal system and an electrical control system.

[0103] See also Fig.11 and Fig.12 According to a third aspect of the present application, there is provided an aerial rail transportation system 3000, comprising an aerial rail system 2000, and the transport vehicle 1000 of any embodiment of the first aspect, or the aerial rail freight train 1100 of any embodiment of the second aspect.

[0104] The sky rail system 2000 includes a pier 2200 and a track beam installed on the pier 2200. Common track beams include a box-type track beam 2100 and an I-shaped track beam. Fig.13 As shown, in some embodiments, the empty rail system 2000 includes a box-type track beam 2100, and the inner wall of the box-type track beam 2100 is provided with a first track 2110 and a second track 2120. The bogie 100 is located inside the box-type track beam 2100, and the lower part of the box-type track beam 2100 is open for the lower end of the suspension device 200 to extend out. The main body of the bogie 100 is a frame 110, and two sets of running wheels 120 and two sets of guide wheels 130 are installed on the frame 110. The running wheels 120 run along the first track 2110, and the guide wheels 130 run along the second track 2120.

[0105] like Fig.13 As shown, in some embodiments, the bogie 100 is driven by a linear motor 800. The stator 820 of the linear motor 800 is arranged on the inner top surface of the box-type track beam 2100, and the mover 810 is arranged on the top of the bogie 100. There is a gap of about 10 mm between the mover 810 and the stator 820 of the linear motor 800. The mover 810 cooperates with the stator 820 to provide traction for the movement of the bogie 100. In some embodiments, the stator 820 is arranged in the middle of the inner top surface of the box-type track beam 2100, located between the two second rails 2120, and the guide wheel 130 can be used to cooperate with the second rail 2120 to ensure that the positional relationship between the stator 820 and the mover 810 is always consistent.

[0106] See also Fig.13 In some embodiments, a current collector 140 is provided on the bogie 100. The current collector 140 uses sliding contact to obtain power and contacts with a power supply rail 2130 on the track beam of the empty rail system 2000. The power supply rail 2130 is connected to the traction power supply system to supply power to the electrical devices on the collective motion vehicle 1000.

[0107] Specifically, the power rail 2130 and the current collector 140 are always in contact, and all electrical devices on the integrated motion vehicle 1000 are powered by the power rail 2130. Electric energy is input from the current collector 140 and enters the high-voltage control box 520. The high-voltage control box 520 branches and outputs electric energy, which enters the traction inverter 510 and the auxiliary transformer box 560 respectively. The traction inverter 510 supplies power to the linear motor 800, and the electric energy output by the auxiliary transformer box 560 is stepped down to 220V, 110V, and 24V to supply power to other electrical devices on the integrated motion vehicle 1000.

[0108] Taking the application in coal mines as an example, the working process of the sky rail transportation system 3000 is as follows:

[0109] 1. Starting and transporting: The integrated motion vehicle 1000 overcomes resistance and moves by electromagnetic force when the linear motor 800 is powered on. The driving force is controlled by controlling the current of the motor coil, and the direction of the electromagnetic force is controlled by the direction of the current to achieve acceleration or deceleration of the vehicle.

[0110] 2. Braking or parking: Positioning sensing points are set on the four beams of the coal loading position. When the coal collecting vehicle 1000 detects the reflected signal of the sensing point, it slows down to a stop. By controlling the current reversal of the linear motor 800, the electromagnetic drive is converted into an electric braking force in the opposite direction. At the same time, the tread brake 150 is controlled to act on the running wheel 120 to slow down the vehicle to a stop. When the vehicle is parked for a long time, the brake unit of the top rail brake is against the track to prevent the vehicle from slipping.

[0111] 3. Coal loading and unloading by changing boxes: By cooperating with the rapid box-changing platform system disclosed in patent CN116675023A, rapid loading and unloading of special coal boxes can be realized; at the unloading point, the flat-bottom box loaded with lump coal can be unloaded from the collecting vehicle 1000 through the lifting and side-shifting platform of the rapid box-changing platform system, and then transported to the coal station by the collecting truck, or the coal unloading port at the bottom of the hopper box can be controlled to open through the ground-driven opening and closing device to unload the fine coal into the coal unloading pit.
