Description
Technical Field
[0001] The present invention belongs to the technical field of rail transportation, and in particular relates to an automated workshop passage device for rail transportation vehicles. Background Art
[0002] Railways are one of the world's most important modes of transportation today, and they have long been used to transport supplies and troops. As the functional demands on railway vehicles grow, specialized rail transit vehicles have evolved from solely transporting supplies to integrating transportation, command, and combat capabilities. As specialized equipment, these vehicles must meet the functional requirements of mobility, automation, and concealment. Conventional specialized rail transit vehicles are standard railway-owned vehicles with no pedestrian access between adjacent carriages, preventing the passage of passengers when the vehicle is stationary or in motion. Standard urban rail, ordinary, and high-speed trains feature a gangway between adjacent carriages.
[0003] The gangway system, also known as a windshield, is located at the junction of two carriages and serves as the connecting portion of the two vehicle aisles. It provides excellent protection against rain, wind, dust, sound, and heat, allowing passengers to travel safely between vehicles. Currently, it can be divided into integral and split types based on the connection method. In both cases, one end of the bellows is connected to the end of the vehicle body, and the connection is manually connected and remains in place for a long time. However, this structure has drawbacks in specialized applications. If the gangway system remains connected, it will affect the camouflage effect of the entire vehicle. Furthermore, manual operation cannot meet the requirements for military use, such as speed, safety, and emergency response. Summary of the Invention

DETAILED DESCRIPTION
[0029] In order to make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention. That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein may be arranged and designed in various different configurations.
[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but is merely intended to represent selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.
[0031] See also Figure 1-2 As shown, in an embodiment of the present invention, an automated workshop access device for rail transit vehicles includes two frame assemblies 1, a plurality of scissor drive assemblies 2, two bellows assemblies 3, and a control system 4. The two frame assemblies 1 are arranged relative to each other. The fixed ends of the scissor drive assemblies 2 are fixedly connected to the corresponding frame assemblies 1. One end of each of the two bellows assemblies 3 is fixedly connected to the corresponding frame assembly 1, and the other end of the bellows assemblies 3 is transmission-connected to the output ends of the plurality of scissor drive assemblies 2. The control system 4 is electrically connected to the scissor drive assemblies 2.
[0032] Two frame assemblies 1 are located on each end of the carriage, housing the scissor drive assembly 2 and bellows assembly 3. The scissor drive assembly 2 provides power to the bellows assembly 3, driving its extension and retraction. When both bellows assemblies 3 are extended, a passageway is created for personnel to pass through. A control system 4 controls the scissor drive assembly 2 to achieve the desired functional actions. The frame assembly 1, scissor drive assembly 2, bellows assembly 3, and control system 4 work together to achieve automatic docking of the workshop passageway.
[0033] See also Figure 3 As shown, the skeleton assembly 1 includes a scissor-type mounting frame 11, a bellows mounting frame 12, and several sliding rails 13. The fixed end of the scissor-type drive assembly 2 is fixedly connected to the scissor-type mounting frame 1. Several sliding rails 13 are provided on the side walls of the scissor-type mounting frame 11. The bellows mounting frame 12 is slidably connected to the sliding rails 13. One end of the bellows assembly 3 is fixedly connected to the bellows mounting frame 12. The scissor-type mounting frame 11 and the bellows mounting frame 12 are connected as a whole via the sliding rails 13, allowing the bellows mounting frame 12 to slide linearly within the scissor-type mounting frame 11 via the sliding rails 13. Driven by the bellows mounting frame 12, the bellows assembly 3 can also slide within the scissor-type mounting frame 11, providing the structural foundation for the bellows assembly 3 to be concealed.
[0034] See also Figure 8 As shown, the scissor lift mounting frame 11 includes a U-shaped bent plate crossbeam 111, a square tube crossbeam 112, an L-shaped bent plate crossbeam 113, a guide rail mounting plate 114, a dust cover 115, and a scissor lift drive assembly mounting base 116, all welded together as a single unit. The scissor lift drive assembly mounting base 116 is fixedly connected to the U-shaped bent plate crossbeam 111 for mounting the scissor lift drive assembly 2, while the guide rail mounting plate 114 is fixedly connected to the square tube crossbeam 112 for mounting the slide track 13. The dust cover 115 covers the outer periphery of the slide track 13 to protect it from rain and dust. The L-shaped bent plate crossbeam 113 has a slot to provide space for the output end of the scissor lift drive assembly 2 to extend and retract.
[0035] See also Figure 3 As shown, the bellows mounting frame 12 comprises an aluminum alloy plate 121, an aluminum alloy U-shaped profile 122, and several spring latches 123. The aluminum alloy plate 121 is used to connect to the bellows assembly 3 and defines a communication opening, providing space for personnel passage. The aluminum alloy U-shaped profile 122 is arranged circumferentially along the communication opening of the aluminum alloy plate 121, thereby enhancing the strength of the passageway at the communication opening. Several spring latches 123 are located on the side of the aluminum alloy plate 121 away from the bellows assembly 3. They are used to insert the bellows assembly 3 into the vehicle side wall for secondary protection after it is extended.
[0036] See also Figure 4As shown, the scissor drive assembly 2 includes a scissor assembly 21, a screw assembly 22, and a scissor mounting base plate 23. The scissor mounting base plate 23 is connected to the scissor assembly 21 and the screw assembly 22 by screws to form a module, and the scissor drive assembly 2 is connected to the scissor mounting frame 11 by screws. The screw assembly 22 is mounted on the scissor mounting base plate 23. The screw assembly 22 is driven by the motor to achieve the back-and-forth movement of the sleeve. The fixed end of the scissor assembly 21 is fixedly connected to the scissor mounting base plate 23. The scissor assembly 21 is connected to the sleeve on the screw assembly 22. The output end of the scissor assembly 21 is driven by the sleeve on the screw assembly 22 to achieve axial back-and-forth movement.
[0037] Further, see Figure 4 and Figure 5 As shown, the scissor assembly 21 includes a scissor arm mechanism 211, an electromagnet mounting seat 212, an electromagnet 213, a travel switch 214 and an adapter plate 215. The scissor arm mechanism 211 is a scissor structure, consisting of a number of scissor units, each of which is composed of two or more rods and a hinge connection point. The local small-scale swing of the rod can achieve a large-stroke telescopic effect. A hinge connection point near the fixed end of the scissor arm mechanism 211 is hinged to the adapter plate 215 through a pin, and then the scissor arm mechanism 211 is fixedly connected to the sleeve on the screw assembly 22 through the adapter plate 215. When the sleeve of the screw assembly 22 moves, the sleeve drives the hinge connection point connected to it to move through the adapter plate 215. During the movement, the connecting rods hinged to each other on the scissor arm mechanism 211 change their angles, thereby realizing the telescopic effect of the scissor arm mechanism 211.
[0038] One end of the scissor arm mechanism 211 is fixedly connected to the scissor mounting base 23, and the other end is fixedly connected to the electromagnet 213 via the electromagnet mounting base 212. When the scissor arm mechanism 211 is extended or retracted, the electromagnet mounting base 212 pushes the electromagnet 213. When the electromagnet 213 extends, it pushes the bellows assembly 2 out and into docking. Because the electromagnet 213 is magnetic when energized, it can attract and retract the bellows assembly 2, thus enabling the bellows assembly 2 to extend and retract. A limit switch 214 is provided on the electromagnet 213, which sends a signal to stop the movement of the electromagnet 213.
[0039] The scissor assembly 21 also includes several tension springs 216. Two connecting rods 2111 at the ends of the scissor arm mechanism 211 are hingedly connected to the electromagnet mounting base 212. At least one tension spring 216 is disposed between each of the two connecting rods 2111 and the electromagnet mounting base 212. The tension springs 216 apply tensile stress between the connecting rods 2111 and the electromagnet mounting base 212 on both sides, thereby balancing the forces on both sides of the electromagnet mounting base 212 and correcting the deflection angle of the electromagnet 213.
[0040] See also Figure 6 As shown, a plurality of magnetic plates 31 are provided on the bellows assembly 3. The plurality of magnetic plates 31 are arranged opposite to the corresponding electromagnets 213. When the electromagnets 213 are energized and have magnetism, they can attract the magnetic plates 31, making it convenient to retract the magnetic plates 31 and shrink the bellows assembly 3.
[0041] The lead screw assembly 22 drives the scissor assembly 21, which in turn drives the electromagnet 213 in linear motion. The electromagnet 213 then attracts the magnetic plate 31, driving the bellows assembly 3 in motion, enabling the extension and retraction of the bellows assembly 3. A travel switch 214 limits the travel of the lead screw assembly 22. The scissor assembly 21 can be installed within the limited space of a locomotive car. Combining the long travel of the scissor structure with the extension and compression capabilities of the bellows assembly 22, it enables the establishment of a passageway even when the distance between adjacent car ends varies.
[0042] The bellows assembly 3 includes a docking frame 32, a folding tent fabric 33, several spring rod assemblies 34, several anti-collision guide rods 35, and a pedal 36. The folding tent fabric 33 is composed of a silicone tent fabric and aluminum profile fixing strips. It is ductile and compressible, allowing it to expand and contract. The folding tent fabric 33 is installed between the bellows mounting frame 12 and the docking frame 31. When the bellows mounting frame 12 slides, it can move the folding tent fabric 33 into the frame assembly 1.
[0043] The spring rod assembly 34 provides both telescopic and adjustable support functions. Its ends are hingedly connected to the bellows mounting frame 12 and the docking frame 32, respectively, enabling the bellows assembly 3 to stably extend and retract and support the weight of pedestrians. The spring rod assembly 34 is adjustable, allowing the tension of the spring within it to be adjusted. Furthermore, the spring rod assembly 34 can utilize a gas spring strut, allowing the tension of the spring rod assembly 34 to be adjusted by varying the amount of gas charged.
[0044] The amount of channel droop can be controlled by adjusting the spring rod assembly 34. After long-term use, the channel may sag, which can be alleviated by adjusting the spring tension. Furthermore, after the folded awning sheet 33 is extended to create the channel, the soft silicone material lacks rigidity and has a poor load-bearing capacity, posing a safety hazard to personnel passing through. However, the spring rod assembly 34, in its stretched state after the channel is established, stabilizes channel sway, improves channel rigidity, and effectively ensures safe passage.
[0045] A plurality of anti-collision guide rods 35 are provided between the folding shed mounting frame 12 and the docking frame 32 to prevent the folding shed cloth 33 from being compressed excessively and play a protective role. A pedal 36 is fixedly connected to the docking frame 31 for people to pass through and step on.
[0046] Control system 4 includes a control box and a driver box. The control box is equipped with a display screen, an industrial keyboard, an emergency stop button, and other features. The operator uses the control box to control the extension, docking, and retraction of the workshop docking device. The driver box houses a single-chip microcomputer, which works in conjunction with the control box to control the extension, docking, and retraction of the workshop docking device.
[0047] See also Figure 2 、 Figure 5 and Figure 7 As shown, the automated rail transit vehicle access device provided by the present invention is installed at the ends of adjacent carriages. The frame assembly 1 is secured to the concave area within the carriages using hexagon socket head screws. The scissor drive assembly 2 is extended and retracted by a control system 4. The scissor drive assembly 2 uses electromagnets 213 to attract the magnetic plate 31, driving the bellows assembly 3 to extend and retract. Once retracted, the bellows assembly 3 is completely concealed within the carriage end face, providing effective concealment and camouflage.
[0048] The above content is merely an example and explanation of the structure of the present invention. Those skilled in the art may make various modifications or additions to the described specific embodiments or replace them in a similar manner. As long as they do not deviate from the structure of the invention or exceed the scope defined by the claims, they should all fall within the scope of protection of the present invention.
