Description

Technical Field

[0001] This invention relates to the field of railway signaling, and in particular to a combined multi-functional manned railcar. Background Technology

[0002] In the field of railway signaling, due to the high frequency and safety characteristics of railway transportation, it is necessary to frequently carry out construction, maintenance and repair of track signaling equipment. The signaling equipment is mostly evenly arranged along the track. When carrying out on-site construction work, it is necessary to transport construction personnel and equipment tools to different work points. Different construction modes often use different types of cargo or personnel rail transport vehicles to transport personnel and equipment.

[0003] Due to the systematic and integrated nature of railway signaling equipment, there are various construction modes on site from the initial construction of the track to the later maintenance of the equipment, such as equipment installation, maintenance, inspection, and rapid repair. Each construction mode requires a different number of construction personnel and tools and equipment, and the corresponding track vehicles need to have different transportation functions such as carrying people, carrying goods, and carrying multiple people. In traditional construction operations, each transportation need has its own corresponding transport vehicle model according to the different carrying capacities required by the task.

[0004] For initial equipment installations requiring multiple workers at multiple locations simultaneously, the railcar needs to carry the workers, equipment, and installation tools. In this case, large personnel and equipment railcars are often used. Personnel and equipment are unloaded at each work site, and then transported back to the work site after completion. However, large railcars can only operate during track maintenance "windows," resulting in delayed transport and inability to pass through track obstructions, leading to low work efficiency. See also Figure 1 Schematic diagram of other types of large manned rail transport vehicles.

[0005] Equipment upgrades and maintenance require replacing equipment parts at each installation point. In most cases, a small number of workers carry the parts and replace them gradually along the track. The corresponding track vehicle needs to carry both a small number of workers and a large number of equipment parts. In this situation, a cargo track vehicle is often used. However, due to the small number of personnel, the cargo track vehicle is large and heavy, making it inconvenient to move it on and off the track. See also Figure 2 Schematic diagram of other types of rail transport vehicles.

[0006] Equipment inspection requires inspectors to check each equipment installation point along the track one by one, looking for any abnormalities, loose bolts, etc. This is usually done by a single person following the inspection requirements, carrying a few tools such as lighting and recording equipment. Lightweight, single-person track vehicles are often used for this purpose; their small size and light weight allow for rapid inspection. See also Figure 3 Schematic diagram of other types of single-person rail transport vehicles.

[0007] For rapid repairs, if equipment malfunctions at an installation point, construction personnel often need to carry a small amount of equipment parts and tools to handle the issue. To meet the limited needs for carrying personnel and goods, medium-sized manned railcars are frequently used for quick response. See also Figure 4 Schematic diagram of other types of medium-sized manned rail transport vehicles.

[0008] This shows that different transportation needs require different vehicle types, resulting in a large number of vehicle types at each depot, increasing procurement costs, hindering construction management, and causing low efficiency. Therefore, there is an urgent need for a modular, multi-functional, universal railcar that is portable and can be assembled and transformed as needed. A single vehicle can perform various transportation functions such as passenger transport, cargo transport, multi-person transport, and inspection, meeting all transportation needs at the rail site from initial construction to later maintenance. Furthermore, it should have a simple structure, be portable and lightweight, improve construction efficiency, and reduce usage and later maintenance costs. Summary of the Invention

[0009] To address the aforementioned needs, this invention provides a modular multi-functional manned railcar that can meet the transportation requirements of different construction modes, such as carrying people, goods, multiple people, and inspection, and can efficiently and conveniently meet all construction operation modes on railway sites.

[0010] The basic configuration of the modular multi-functional manned railcar of this invention is a single-person vehicle and a two-person vehicle. Different task modules can be added on this basis to combine and transform it to adapt to different transportation needs.

[0011] This invention provides a combined multi-functional manned rail vehicle. The single-person vehicle includes a power module, a load-bearing beam assembly, a seat, motor wheels, driven wheels, a main crossbeam, manual clamps, a telescopic crossbeam, and a control handle.

[0012] The load-bearing beam assembly includes a load-bearing beam, a foot pedal, a U-shaped lock, a mounting plate, a crossbeam seat, and a locking buckle.

[0013] The power module is fixed to the load-bearing beam by a locking buckle, and can be quickly disassembled, facilitating the replacement of the power module during on-site construction and meeting the requirements for long-term or long-distance maintenance.

[0014] The main crossbeam is fixed to the load-bearing beam via the crossbeam seat, and the telescopic crossbeam is fixed to the main crossbeam via manual clamps. The telescopic crossbeam is designed with a deflector wheel. The load-bearing beam and the main crossbeam are made of high-strength aluminum alloy and carbon fiber, resulting in high overall strength.

[0015] The motor wheel and the driven wheel are fixed to the front and rear ends of the load-bearing beam by bolts, and the motor wheel and the driven wheel rest on the same side rail surface;

[0016] The main crossbeam is a hollow round tube, which serves as a lateral support structure. One end is connected to the load-bearing beam, and the other end is connected to the telescopic crossbeam via a manual clamp. The outer diameter of the telescopic crossbeam and the inner diameter of the main crossbeam are matched in size. After the manual clamp is released, it can be extended into the main crossbeam for portability.

[0017] The vehicle's center of gravity is designed to be located inside the single-sided track, with the center of gravity position close to the supporting rail surface, thus achieving a frameless structure.

[0018] During equipment inspection, a lightweight cargo vehicle can be added to the back of the single-person vehicle. The lightweight cargo vehicle is equipped with a U-shaped towing hook, which can be connected and fixed to the telescopic crossbeam of the single-person vehicle. During on-site construction, the cargo vehicle can carry a small amount of equipment and tools, forming a single-person cargo carrying mode.

[0019] The railcar of this invention is highly flexible in use. One vehicle can meet the transportation needs of different construction modes, such as carrying people, carrying goods, carrying multiple people, and inspection. It efficiently and conveniently meets all construction operation modes on railway sites. Attached Figure Description

[0039] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help to further understand the present invention, but are not intended to limit the invention in any way. It should be noted that several modifications and improvements can be made without departing from the inventive concept, and these all fall within the scope of protection of the present invention.

[0040] Due to the long construction distances and the need to transport tools and equipment, track-mounted vehicles are mostly used for on-site track construction. Traditional track-mounted vehicles come in various models, such as single-person, medium-sized, cargo-carrying, and multi-person models. Different construction modes require track-mounted vehicles with corresponding functions. The wide variety of vehicle types and models makes construction management inconvenient, and the procurement and subsequent maintenance costs are also high. This invention is a modular multi-functional manned track-mounted vehicle. Through combination and deformation, it can form various configurations such as manned, cargo-carrying, and multi-person vehicles. One vehicle can meet all the transportation needs of on-site track construction, with comprehensive functions, reducing application and subsequent maintenance costs. At the same time, it has a simple structure, is easy to assemble and combine, is portable and lightweight, and is convenient to transport, thus improving work efficiency.

[0041] For example, in the initial equipment installation, multiple people need to carry out the installation at multiple points simultaneously. The corresponding railcar needs to carry multiple people and the corresponding equipment and installation tools at the same time. In this case, the multi-person cargo vehicle of the present invention can be used. It can be assembled from multiple basic two-person vehicles with combined connecting rods and cargo support plates.

[0042] For equipment upgrades and maintenance, the corresponding railcar needs to carry a small number of construction workers and a large number of equipment parts. At this time, a two-person car can be connected with a load-bearing support plate to form a load-bearing car. At the same time, depending on the quantity and weight of the load, multiple load-bearing cars can also be connected and combined, which is flexible in operation and highly efficient in use.

[0043] Equipment inspections are usually carried out by a single person according to the inspection requirements, while carrying a small number of tools such as lighting and video recording. In this case, the basic configuration of the single-person vehicle of the present invention can be used. Depending on the number and weight of the tools carried, a cargo transport vehicle can also be added. The whole system is portable and lightweight, and can be carried and transported by a single person.

[0044] For quick repairs, construction personnel need to carry a small amount of equipment, parts, and tools to handle the situation. For a small number of people and goods, the basic configuration of this invention can be used to connect a two-person vehicle with a cargo support plate. Two single-person vehicles can also be combined into a two-person vehicle, making it flexible and convenient to use.

[0045] This invention relates to a modular multi-functional manned railcar that can be assembled and deformed. It can be combined and disassembled into different vehicle configurations according to construction needs. It is convenient to use, simple to operate, and has a single vehicle type structure. It is also easy to maintain later. It can safely and conveniently transport workers or equipment tools to the work site, thereby improving work efficiency.

[0046] The basic configuration of the modular multi-functional manned railcar of this invention is a single-person vehicle and a double-person vehicle. Based on this, structural combinations and connections can be made to form various configurations such as cargo-carrying and multi-person vehicles.

[0047] Figure 5 This is a schematic diagram of the single-person vehicle structure of the present invention, including a motor wheel 1, a load-bearing beam assembly 2, a seat 3, driven wheels 4, a main crossbeam 5, a manual clamp 8, a telescopic crossbeam 9, and a control handle 16. The load-bearing beam assembly 2 includes a power module 6, a foot pedal 7, a U-shaped lock 11, a mounting plate 12, a crossbeam seat 13, and a locking buckle 15 (see [reference]). Figure 6The specific implementation process of the present invention is as follows: the motor wheel 1 and the driven wheel 4 are fixed to the front and rear ends of the load-bearing beam assembly 2 by bolts, respectively. They are equipped with rolling bearings inside and can rotate smoothly on the rail surface. The motor wheel 1 is designed with a drive motor to provide forward power. The load-bearing beam assembly 2 includes a power module 6, a foot pedal 7, a U-shaped latch 11, a mounting plate 12, a crossbeam seat 13, a locking buckle 15, and a load-bearing beam 17. The power module 6 is fixed to the load-bearing beam assembly 2 via the locking buckle 15 and can be quickly disassembled for easy replacement during on-site construction, meeting the requirements for long-term or long-distance maintenance. It integrates a battery and control circuit. The battery provides power to drive the motor rotation, and the control circuit is connected to the control handle 16 via Bluetooth. Manual operation of the control handle 16 can control the motor speed, enabling control modes such as uniform speed and acceleration of the track vehicle. The foot pedal 7 provides a footrest position for passengers, improving riding comfort. The U-shaped latch 11 is used to connect and fix the load-bearing beam 17 and the mounting plate 12. The mounting plate 12 is designed with mounting holes for connecting and fixing the seat 3 and the crossbeam seat 13, respectively. The seat 3 provides space for passengers. The crossbeam seat 13 is used to fix the main crossbeam 5. The main crossbeam 5 serves as a transverse support structure, with one end connected to the load-bearing beam assembly 2 and the other end connected to the telescopic crossbeam 9 via a manual clamp 8. The telescopic crossbeam 9 and the main crossbeam 5 have matching pipe diameters. After the manual clamp 8 is released, the telescopic crossbeam 9 can be extended into the main crossbeam 5 for portability. The telescopic crossbeam 9 is designed with a deflector wheel 10. The deflector wheel 10 rests on the rail surface on the other side and, together with the motor wheel 1 and the driven wheel 4, provides support.

[0048] This invention relates to a single-person vehicle that utilizes a high-capacity lithium iron phosphate battery, offering high energy density, long cycle life, and excellent safety performance. Combined with high-load-bearing motor wheels, the vehicle achieves a maximum speed of 15 km / h and a range of 30 km. The battery employs a quick-release locking buckle, allowing for rapid replacement of a spare battery during long-distance transport, thus extending the operating range. The vehicle's load-bearing beams and main crossbeams are constructed from high-strength aluminum alloy and carbon fiber, resulting in high overall strength. The single-person vehicle can carry a maximum load of 180 kg.

[0049] The single-person vehicle of this invention has a simple structure, is lightweight, and can be shrunk to a small size, making it convenient for a single person to carry during construction. Figure 7 This is a schematic diagram of the telescopic structure of a single-person vehicle. Other types of railcars in China mostly use fixed mechanical structures, which are large and inconvenient to transport. This design uses a telescopic structure for the single-person vehicle. The main crossbeam 5 is a hollow circular tube. The outer diameter of the telescopic crossbeam 9 and the inner diameter of the main crossbeam 5 are designed to match. After loosening the manual clamp 8, the telescopic crossbeam 9 can extend into the main crossbeam 5, reducing its size and achieving portability. See [link to diagram] for the non-telescopic (working) state. Figure 5 See the diagram for the state after scaling down. Figure 7 This solution is portable and practical, and can be transported by a single person, making it convenient for single-person on-site construction operations.

[0050] Figure 8A This is a schematic diagram of the basic configuration of the single-person vehicle track operation according to the present invention. During on-site implementation, the motor wheel 1 and driven wheel 4 rest on the same side of the track. The manual clamp 8 is loosened, and the telescopic beam 9 is adjusted to allow the offset wheel 10 to rest on the other side of the track. The manual clamp 8 is then tightened to fix the telescopic beam 9, completing the assembly of the single-person vehicle. During on-site construction, personnel sit in seat 3 and adjust the motor speed inside motor wheel 1 using control handle 16 to control the forward movement and acceleration of the track vehicle. Depending on the needs of the on-site construction task, a lightweight cargo cart 22 can also be added to the rear of the vehicle (see [reference]). Figure 8B The lightweight cargo vehicle 22 is equipped with a U-shaped towing hook, which can be connected and fixed to the telescopic crossbeam 9 of the single-person vehicle. During on-site construction, the cargo vehicle can carry a small amount of equipment and tools, forming a single-person cargo carrying mode.

[0051] The basic configuration of the single-person vehicle of this invention can meet the needs of single-person inspection during on-site construction. It has a simple structure and creatively designs the center of gravity of the whole vehicle to be inside the single-sided track. The center of gravity is close to the supporting rail surface, realizing a frameless structure. The weight of the whole vehicle does not exceed 7Kg, which can be carried by a single person and facilitates the single-person on-site construction operation mode.

[0052] Figure 9 This is a schematic diagram of a two-person manned railcar structure. The two-person and single-person manned vehicle structures of this invention are interchangeable. Two single-person manned vehicles can be quickly assembled into a two-person manned vehicle through combination and overlapping. (See attached diagram.) Figure 9 Two single-person vehicles are placed symmetrically. The manual clamps 8 are loosened, and the telescopic crossbeam 9 is removed. A connecting crossbeam 14 connects the two manual clamps 8. The main crossbeam 5 is a hollow circular tube, with its inner diameter matching the outer diameter of the connecting crossbeam 14. The connecting crossbeam 14 can extend and retract axially within the main crossbeam 5. By adjusting the extension and retraction of the connecting crossbeam 14 within the main crossbeam 5, the motor wheels 1 and driven wheels 4 on both sides can be positioned on the rail surfaces, thus enabling a combination switch from a two-person vehicle to a single-person vehicle. The telescopic design also adapts to different track gauges, expanding its application range. Similarly, a two-person vehicle can be disassembled into two single-person vehicles. The manual clamps 8 are loosened, and the connecting crossbeam 14 is removed. Telescopic crossbeams 9 are installed at the two manual clamp positions. The outer diameter of the telescopic crossbeam 9 matches that of the main crossbeam 5, allowing it to extend and retract axially. By adjusting the extension and retraction, the offset wheel 10 is positioned on the rail surface, resulting in two single-person vehicles. The single-person vehicles can also adapt to different track gauges by adjusting the extension and retraction of the telescopic crossbeam 9. This solution features a modular structure that is flexible and convenient to use. It can ensure that two people can work simultaneously or separately. The telescopic design can adapt to different track gauges, improving task scalability. At the same time, the size is reduced after disassembly, making it convenient for transportation and carrying.

[0053] Figure 10This is a schematic diagram of the operation of a two-person manned railcar. During on-site implementation, the motor wheel 1 and driven wheel 4 rest on the same side of the rail. The manual clamp 8 is loosened, and the extension / retraction of the connecting beam 14 is adjusted so that the motor wheel 1 and driven wheel 4 on the other side rest on the other side of the rail. The manual clamp 8 is then tightened to fix the connecting beam 14, completing the assembly of the two-person railcar. During on-site construction, personnel sit in seat 3 and adjust the speed of the motor inside motor wheel 1 using the control handle 16 to control the forward movement and acceleration of the railcar.

[0054] The invention's two-person vehicle adopts a modular design, which is simple to operate and use. In case of rapid maintenance or other construction needs requiring the use of a two-person vehicle, two single-person vehicles can be quickly assembled into a two-person vehicle, which improves the vehicle utilization rate. The maximum load capacity can reach 260Kg, meeting the load-bearing requirements in two-person mode.

[0055] Figure 11A This is a schematic diagram of the multi-person vehicle structure of the present invention. When multiple people are required for construction, the two-person vehicle of the present invention can be combined to form a multi-person vehicle. See also Figure 11B The diagram illustrates the combination and connection method of multi-person vehicles. The front end caps of the load-bearing beams 17 on both sides of the two-person vehicle are designed with threaded holes, and one end of the connecting shaft 18 is designed with a matching threaded post, allowing for rotatable connection. One end of the connecting shaft 18 is designed with a transverse through hole, which is inserted axially into the rear end caps of the load-bearing beams 17 on both sides of the preceding two-person vehicle. The load-bearing beams 17 are also designed with upper and lower through holes. A pin 19 is inserted from top to bottom into the through holes of the load-bearing beams 17 and the connecting shaft 18, thus completing the combination and connection of the two two-person vehicles. Depending on the different construction needs, the above fastening connection operation can be repeated to combine and connect multiple two-person vehicles in the same way to form a multi-person vehicle. This method is flexible and convenient, meeting the needs of transporting multiple people during on-site construction. (See also...) Figure 11C Schematic diagram of multi-person vehicle track operation.

[0056] Figure 12A This is a schematic diagram of the multi-person cargo vehicle structure of the present invention. When there is a need for cargo transportation during on-site construction, a loading platform can be added to a two-person or multi-person vehicle to form a cargo vehicle. See also Figure 12B The diagram illustrates the assembly and connection method of the cargo vehicle. The upper surfaces of the two load-bearing beams 17 have pre-drilled mounting holes for cargo platforms. The cargo support plates 20 are fixed to the corresponding holes on the load-bearing beams 17 using four fastening bolt assemblies 21, thus forming the cargo vehicle. The number of cargo support plates 20 can be selectively installed depending on the quantity and weight of the goods to be carried. During on-site construction, tools and equipment are placed on the cargo support plates 20, and personnel sit on the seats 3. Depending on the construction needs, cargo vehicles with different carrying capacities and load capacities can be formed. (See attached diagram). Figure 12C A schematic diagram of the track operation for a multi-person freight vehicle. It can meet the needs of carrying goods with few people as well as carrying goods with many people, offering comprehensive functionality and improving the scalability of transportation tasks.

[0057] This invention presents a modular multi-functional manned railcar. Based on single-person and double-person vehicles, it can be combined and assembled to form cargo vehicles, multi-person vehicles, and multi-person cargo vehicles. A single vehicle can meet various transportation needs, including single-person, cargo, multi-person, and inspection needs. Other types of railcars in China are mostly single-function, requiring different models for different transportation needs, resulting in high procurement and maintenance costs and inconvenience for construction management. This invention's modular railcar, through combination and transformation, can be converted into different models, offering comprehensive functions, portability, lightweight design, and flexible use. It significantly reduces subsequent maintenance costs and improves operational efficiency.

[0058] The above description is merely a specific embodiment of the present invention and should not be used to limit the scope of protection of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the scope of protection of the present invention.
