Description

Technical Field

[0001] The utility model belongs to the technical field of electric locomotives, in particular to an unmanned electric locomotive for a tunnel. Background Art

[0002] Currently, domestic tunnel transportation systems still rely primarily on manual command and dispatch. This model requires real-time control of transport vehicles through walkie-talkies and manual signals. Dispatchers must frequently track and direct vehicles' operating status, location, and mission progress. Because information transmission and processing rely heavily on manual operations, this system is inefficient and susceptible to human interference, making it difficult to meet the increasingly complex needs of tunnel transportation.

[0003] During the manual command and dispatch phase, the level of intelligence in tunnel transportation systems was very low. This type of equipment suffered from widespread operational issues such as low efficiency, poor smoothness, and stability. As the mining distances of some tunnels increased, transportation distances also increased. Traditional transportation equipment often required excessively long single-sided transport times, significantly increasing operating costs and safety risks for workers during tunnel operations. Utility Model Content

[0004] The purpose of the present utility model is to provide an unmanned electric locomotive in a tunnel to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0005] Provided is an unmanned electric locomotive for a tunnel, comprising a body system, wherein traction systems are provided at both ends of the body system, an anti-slip system is provided on the upper portion of the body system, both sides of the upper portion of the body system are connected to a traveling system via a suspension system, a basic braking system, an electrical system, and an air braking system are also provided on the upper portion of the body system, and an unmanned driving system is also provided at the front end of the body system. The electrical system adopts a one-to-two control mode to control the speed of the traction motor, and the torque of the traction motor is transmitted to the wheelset via a gearbox.

[0006] Furthermore, the vehicle body system is a monolithic load-bearing structure constructed from welded steel plates. This welded steel structure possesses excellent mechanical properties, evenly distributing and transmitting the various loads borne by the vehicle body, including static loads (such as equipment weight) and dynamic loads (such as operational vibration and impact). This welded monolithic structure avoids loose connections and stress concentration, enhancing the rigidity and strength of the vehicle body. This provides solid support during vehicle operation, ensuring the stability and durability of the overall structure.

[0007] Furthermore, the vehicle body system includes a front driver's cab, a middle mechanical and electrical room, and a rear air compressor room. The front driver's cab is welded together with the front chamber and ceiling. It is equipped with a driver's console, automatic brake valve, relay valve, automatic switch, vehicle operation safety system, and vehicle automatic driving system. The mechanical and electrical room is equipped with a frequency converter, reactor, and direct current converter; the rear air compressor room is equipped with an air compressor unit, distribution valve, and air tank. The compartmentalized design of the vehicle body system modularizes control, safety, electrical, and pneumatic functions, improving equipment reliability, operational efficiency, and ease of maintenance. Through the intelligent control of the front driver's cab, the power support of the middle mechanical and electrical room, and the pneumatic support of the rear air compressor room, the subsystems work together to achieve efficient, safe, and intelligent operation of the electric locomotive.

[0008] Furthermore, the unmanned driving system comprises a vehicle operation safety system, an onboard unmanned autonomous driving system, a vehicle management system, and a braking system. The unmanned driving system can be flexibly adjusted according to production needs and adapt to changing tasks.

[0018] See also Figure 1 As shown, in an embodiment of the present invention, an unmanned electric locomotive in a tunnel includes a body system 9, a traction system 2 is provided at both ends of the body system 9, an anti-slip system 1 is provided on the upper part of the body system 9, and a travel system 7 is connected to both sides of the upper part of the body system 9 through a suspension system 8. A foundation brake system 4, an electrical system 5, and an air brake system 6 are also provided on the upper part of the body system 9. An unmanned driving system 3 is also provided at the front end of the body system 9. The electrical system 5 adopts a one-to-two control mode to control the speed of the traction motor, and the torque of the traction motor is transmitted to the wheel set through a gearbox;

[0019] The body system 9 is the basic framework of the electric locomotive, carrying various subsystems, including the travel system 7, traction system 2, anti-skid system 1, etc., providing mechanical strength and stability, supporting various functional modules, and transmitting the force to the wheels and tracks to achieve overall coordinated operation of the equipment.

[0020] The traction system 2 provides the vehicle's driving force, enabling the vehicle to move forward or backward along the track. Under the control of the electrical system 5, the traction motor transmits torque to the wheelset through the gearbox, driving the wheels to roll. Its speed and direction are dynamically adjusted according to operational requirements. The unmanned driving system 3 combines sensors (such as position sensors, acceleration sensors, etc.) to collect operating data, and controls the traction system 2, air brake system 6 and travel system 7 through algorithms and logic to ensure the precise and safe operation of the vehicle in the tunnel. The anti-skid system 1 automatically activates when it detects that the vehicle is stopped through mechanical locking, electronic braking, etc., to enhance the static safety of the vehicle. The suspension system 8 (buffering and stabilization) absorbs the vibration caused by uneven tracks and protects the vehicle structure and on-board equipment; the suspension system 8 uses springs, dampers and other components to reduce impact force, thereby improving the smoothness and comfort of vehicle operation.

[0021] The running system 7 supports and moves the vehicle on the track. Driven by the traction motor, the wheelset rolls, forming contact with the track, and transmitting traction through friction.

[0022] The foundation brake system 4 and the air brake system 6 provide braking force during operation and stopping capability in emergency situations.

[0023] The foundation brake system 4 uses mechanical brakes to control wheel friction for deceleration. The air brake system 6 uses air pressure to control valve and brake disc contact, providing flexible and efficient braking. The electrical system 5 (one-to-two control mode) coordinates the traction motor speeds and controls vehicle power output. Electrical system 5 uses a one-to-two mode, where a single control unit simultaneously controls both traction motors. By precisely adjusting motor output, this ensures synchronized wheel rotation and provides stable power.

[0024] The unmanned driving system 3 is the core, coordinating the electrical system 5, traction system 2, and foundation brake system 4 to dynamically adjust operating parameters based on operating conditions (such as slope, speed limit, and load). The anti-slip system 1 is combined with the foundation brake system 4 to ensure the vehicle's parking and emergency response capabilities in any state. Automated control reduces manual intervention, reduces the probability of misoperation, and improves operational efficiency.

[0025] Through the organic integration of various subsystems, this electric locomotive achieves unmanned driving, intelligent control, precise traction, and safe braking. Its core advantage lies in its highly intelligent control logic, which ensures safe and efficient operation, making it suitable for application scenarios in complex environments such as tunnels.

[0026] In one embodiment, see Figure 1The vehicle body system 9 is a monolithic load-bearing structure constructed from welded steel plates. This welded steel structure possesses excellent mechanical properties, evenly distributing and transmitting all loads borne by the vehicle body, including static loads (such as equipment weight) and dynamic loads (such as operational vibration and impact). This welded monolithic structure avoids loose connections and stress concentration, enhancing the rigidity and strength of the vehicle body. It provides solid support during vehicle operation, ensuring the stability and durability of the overall structure.

[0027] Specifically, see Figure 1 As shown, the vehicle body system 9 comprises a front cab, a middle mechanical and electrical compartment, and a rear air compressor compartment. The front cab is welded together with the front compartment and ceiling. It houses the driver's console, automatic brake valve, relay valve, automatic switch, vehicle operation safety system, and autonomous driving system. The mechanical and electrical compartment houses a frequency converter, reactor, and direct current converter; the rear air compressor compartment houses an air compressor unit, distribution valve, and air tank. The compartmentalized design of vehicle body system 9 modularizes control, safety, electrical, and pneumatic functions, improving equipment reliability, operational efficiency, and ease of maintenance. Through intelligent control in the front cab, power support in the middle mechanical and electrical compartment, and pneumatic support in the rear air compressor compartment, the synergistic subsystems enable efficient, safe, and intelligent operation of the electric locomotive.

[0028] Further, see Figure 1As shown, the unmanned driving system 3 is composed of a vehicle operation safety system, an on-board unmanned automatic driving system, a vehicle management system, and a braking system. The unmanned driving system 3 receives instructions from the upper computer according to the set program, and the on-board unmanned automatic driving system of the vehicle will start the vehicle operation. According to the preset program and the preset production scheduling plan, the on-board unmanned driving system 3 will send the instructions that need to be implemented to the execution unit of the vehicle during operation. For example, the reverse operation is achieved by controlling the inverter and the motor. If a warning is required, it is achieved by controlling the horn and other devices, thereby realizing the unmanned operation of the vehicle to the designated location for loading and unloading of goods and other goals. During the operation, the obstacle detection system will detect and identify obstacles and personnel on the vehicle's route. The obstacle detection system can identify objects of not less than 20 cubic centimeters within a hundred meters of the vehicle's route. When the obstacle detection system detects obstacles or personnel that pose a threat to vehicle operation, it reports this in real time to the vehicle operation safety system. The vehicle operation safety system then takes action based on the level of danger. If the danger level is low, the vehicle operation safety system can sound an alarm through the vehicle's automated driving system. If the danger level is high, the vehicle operation safety system will command the braking system to brake the vehicle immediately, bringing it to a rapid stop and ensuring the safety of the vehicle and personnel. Once the danger is resolved, the vehicle operation safety system will release the brakes and send a command to the vehicle's automated driving system. Unmanned Driving System 3 achieves highly intelligent unmanned driving capabilities through the coordinated operation of the vehicle operation safety system, the onboard automated driving system, the vehicle management system, and the braking system. The core principle of this system is to integrate path planning, task execution, obstacle identification, and hazard handling into a closed-loop operation, ensuring autonomous, safe, and efficient vehicle operation in complex environments. Obstacle detection and safety systems respond in real time to ensure the safety of personnel and equipment. Unmanned Driving System 3 can be flexibly adjusted to meet production needs and adapt to changing tasks. Unmanned operation reduces manual intervention and improves scheduling and operational efficiency. Dynamic adjustments to operating behavior based on environmental data optimize the balance between safety and efficiency.
