Description

Technical Field

[0001] This invention relates to the field of traction machine technology, specifically to a modular, combined large-tonnage electric traction machine. Background Technology

[0002] A cable traction machine is a special type of overhead power and communication line construction equipment used to control the traction of cables during installation, ensuring accuracy and safety. Based on different transmission methods, they can be classified as mechanical, hydraulic, hydrodynamic, and electric. Mechanical and hydraulic cable traction machines are mature products, while hydrodynamic transmission is also common abroad.

[0003] To facilitate relocation and transportation, tractor units mostly adopt a trailer-type structure design, which mainly consists of a frame, traction wheel set, tail frame, control box, engine power source, and hydraulic transmission (or mechanical transmission). Currently, hydraulic transmission is the main type used in engineering applications, while mechanical and hydraulic transmissions are relatively less common; and electric tractor units are still relatively rare in domestic and international markets.

[0004] The operating environment of traction machines is quite complex, mostly involving field construction, and frequently encountering high-altitude mountains, hilly areas, and swampy regions. Especially in high-altitude mountainous areas, the terrain is characterized by fault basins, cascading slopes, alternating high mountains and deep valleys, crisscrossing rivers, and numerous lakes, making equipment transportation extremely difficult. Transportation becomes a challenge even in these challenging environments, sometimes requiring the use of cableways to transport equipment to the mountains. However, cableways have weight limitations, generally less than 4 tons per trip. Large-tonnage traction machines are bulky and heavy, and disassembly and transportation are often inconvenient. Furthermore, there are few tools and equipment available on mountains, and assembly conditions are poor, making reassembly impossible.

[0005] To solve this problem, a modular, combined large-tonnage tractor was developed. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this invention provides a modular, combined large-tonnage electric tractor, which solves the severe challenges faced by large-tonnage tractors in ecological nature reserves, such as transportation overloading, assembly difficulties, and high environmental protection requirements.

[0018] Preferably, a cable tray is provided on the top of the frame.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, the present invention provides a method with the following beneficial effects:

[0021] 1. This invention ensures that the weight of a single piece of equipment does not exceed 4 tons through lightweight and modular design, in order to meet the stringent restrictions of mountain cableway transportation; it adopts clean energy power to achieve zero emissions in the construction process, adhering to the ecological protection red line; and with the help of quick connection technology, it enables convenient deployment and efficient assembly of equipment on the mountain, ultimately ensuring that the traction equipment has complete and reliable working performance on site while meeting all environmental protection and transportation requirements.

[0022] 2. This invention utilizes a coordinated design of an energy storage battery module, a traction actuation module, an electric-driven hydraulic tail carriage, and an electric-controlled range extender module. During operation, the energy storage battery module continuously outputs high-voltage power to the traction actuation module and the electric-driven hydraulic tail carriage system. The traction actuation module is responsible for precisely controlling the traction output, while the electric-driven hydraulic tail carriage ensures operational stability by adjusting the tail carriage pressure, guaranteeing stable traction operation. When the system detects insufficient battery power, the electric-controlled range extender module immediately activates to charge the battery, ensuring uninterrupted energy supply. This achieves proactive switching and seamless connection of power sources, effectively eliminating the risk of downtime due to power shortages.

[0023] 3. Compared with traditional mechanical, hydraulic, and fluid-driven traction machines, this invention uses an electric drive system, which greatly simplifies the structure of the mechanical parts. It features small size, light weight, easy centralized control, simple operation, and convenient maintenance. In terms of energy transmission, electric wires replace hydraulic pipelines, facilitating on-site setup. It also facilitates cableway transportation and on-site assembly, solving the problems of use and transportation in high-altitude mountainous areas.

[0024] 4. This invention adopts a pure electric design, making the overall components of the traction machine smaller, lighter, and more efficient in transmission, facilitating centralized control. The entire machine adopts a modular design, with lightweight individual components, facilitating cableway transportation. The electric-driven hydraulic tailstock perfectly combines the precision of electronic control with the high thrust of hydraulics, resulting in a compact structure and simple maintenance, avoiding the potential hazards caused by oil circuit contamination due to frequent disassembly and assembly of the transmission tailstock.

[0039] This invention provides a technical solution:

[0040] Please see Figures 1-7The modular, combined large-tonnage electric traction machine includes a frame 1, a traction force execution module 2, an electric control range extender module 3, an energy storage battery module 4, and an electric-driven hydraulic tailstock 5. Each module weighs less than 4 tons, meeting the requirements for cableway transportation. The traction force execution module 2 is mounted on the frame and includes a motor 21, a gear set 22, and a traction wheel 23. The motor 21 is driven by the gear set 22 and the traction wheel 23. By using a motor-driven traction force execution module 2 and eliminating hydraulic pipelines, the drawback of frequent disassembly leading to contaminants entering the hydraulic system is eliminated, significantly reducing the risk of the entire drive system failing due to contamination. This improves system reliability and service life, and also brings higher efficiency, faster response, simpler maintenance, and better environmental performance. The electric control range extender module 3 includes an electrical cabinet 31 and, within the cabinet, a multi-functional electrical control assembly, a low-voltage power distribution assembly, a motor cooling system, and a range extender engine, providing power to the traction machine and other on-site tools and equipment. The electrical cabinet 31 has heat dissipation windows 32 on its side wall for heat dissipation. The energy storage battery module 4 includes a power supply vehicle 41 and a multi-in-one high-voltage electrical control assembly, a low-voltage power distribution assembly, and a battery thermal management system installed in the power supply vehicle 41. Rollers 42 are rotatably installed on the bottom of both sides of the power supply vehicle 41. A traction frame 43 is fixedly connected to one end of the power supply vehicle 41. A hydraulic support 44 is fixedly installed at the end of the power supply vehicle 41 near the traction frame 43. The electric-driven hydraulic tailstock 5 is located at the tail end of the frame 1. The electric-driven hydraulic tailstock 5 includes a frame body 51 and a movable frame 52. The movable frame 52 is movably installed at the tail of the frame body 51. An electric control cylinder for driving the movable frame 52 to rotate is installed at the bottom of the frame body 51. A cable guide 53 is installed at the top of the frame body 51. The electric-driven hydraulic tailstock perfectly combines the precision of electric control with the high thrust of hydraulics through an electric drive pump station, a highly integrated valve block, and intelligent closed-loop control. It has a compact structure and is easy to maintain.

[0041] In practical use, the working principle of this invention is as follows:

[0042] During operation, the energy storage battery module 4 continuously outputs high-voltage power to the traction force execution module 1 and the electro-hydraulic tail carriage 5 via cable. The traction force execution module 7 is responsible for precisely controlling the traction force output, while the electro-hydraulic tail carriage 5 ensures operational stability by adjusting the tail carriage pressure, guaranteeing stable operation of the traction work. When the system detects insufficient battery power, the electric range extender module 3 will immediately start and charge the battery via cable to ensure uninterrupted energy supply, achieving proactive switching and seamless connection of power sources, effectively eliminating the risk of downtime due to power shortages.

[0043] By employing a motor-driven traction drive module 2 that eliminates hydraulic lines, the drawback of contaminants entering the hydraulic system due to frequent disassembly and reassembly is eliminated, significantly reducing the risk of the entire drive system failing due to contamination. This improves system reliability and lifespan, and also results in higher efficiency, faster response, simpler maintenance, and better environmental performance.

[0044] In summary, compared to traditional mechanical, hydraulic, and hydrodynamic traction machines, this all-electric traction machine, employing electric drive, significantly simplifies the mechanical structure. It features smaller size, lighter weight, easier centralized control, and simpler operation and maintenance. The use of electrical wires instead of hydraulic pipelines facilitates on-site setup. It also facilitates cableway transportation and on-site assembly, solving the challenges of use and transportation in high-altitude mountainous areas. The electric-driven hydraulic tailstock perfectly combines the precision of electrical control with the high thrust of hydraulics, resulting in a compact structure and simple maintenance, avoiding the potential hazards of oil circuit contamination caused by frequent disassembly and reassembly of the transmission tailstock.

[0045] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
