Description

Technical Field

[0001] This invention relates to the field of railway locomotive and rolling stock teaching technology, specifically to a railway locomotive and rolling stock coupling simulation teaching device. Background Technology

[0002] When coupling and uncoupling train cars, in addition to disconnecting and connecting the air hoses, the couplers must also be disconnected. Because of the close contact with the cars during on-site operations, to ensure safety, operators must be familiar with basic theoretical knowledge and follow correct procedures. Currently, most vocational schools cannot provide students with real-world practice in coupling and uncoupling couplers and air hoses, leading to the need for retraining by railway transportation companies after graduation. This device essentially brings railway locomotives and rolling stock into the classroom, not only increasing student interest but also shortening the employee training cycle for railway transportation companies. Based on the actual operation of railway locomotives and the relationship between couplers and air hoses, the overall simulation design of the experimental device needs to meet four functional requirements: 1. Coupling and uncoupling of locomotive and rolling stock couplers; 2. Cutting and opening of train brake hoses; 3. Simulating the air pressure flow state of the train; 4. Real-time monitoring of train operation. Existing simulation teaching devices on the market only perform simple coupling and uncoupling of couplers, failing to realistically simulate the operation of railway locomotives and rolling stock. Our device, however, can achieve a 1:1 recreation of the railway transportation operation site.

[0003] Among the existing teaching equipment on the market, our equipment is a novel device, as it is not yet available. In the teaching of railway locomotive operation, this equipment enables students to learn how to disassemble and replace electric locomotive couplers and replace and connect train brake hoses in actual work. This allows vocational school students to master the disassembly and installation of locomotive brake hoses and couplers before starting their jobs, gaining a basic understanding and familiarity with them. This shortens the on-the-job training time and solves safety problems that arise during operations for railway transportation companies. All of these issues can be simulated in the environment of the equipment itself, thereby solving on-site problems. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0029] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0030] This invention provides a railway locomotive and rolling stock coupling simulation teaching device to meet the business training needs of railway transportation enterprises. It constructs a simulated training system for locomotive crew members in railway transportation enterprises, replicating locomotive operation scenarios and fulfilling students' teaching and training requirements. Through realistic training exercises, students can quickly master operational procedures, enhance their awareness of standard operating procedures, and become familiar with railway technical specifications. Please refer to [link / reference]. Figures 1-2 It includes: track 100, main frame 200, bogie 300, power mechanism 400 and coupling device 500.

[0031] Track 100 uses standard track, with steel rails, sleepers, and ballast roadbed.

[0032] The main frame 200 is set on both sides of the top of the track 100 to simulate the head structure of the car and is used to simulate the coupling of vehicles.

[0033] The bogie 300 is located at the bottom of the main frame 200 and connected to the track 100. The bogie 300 is connected to the track 100 through wheelsets.

[0034] The power mechanism 400 is located inside the bogie 300. The power mechanism 400 uses an electric motor, which is connected to the drive wheel on the bogie 300 via a belt to move the vehicle. A power supply connected to the power mechanism 400 is located within the main frame 200 to power the electric motor. A remote control device connected to the power mechanism 400 is also located within the main frame 200, enabling manual / remote locomotive movement. This allows for the coupling and uncoupling of locomotives and vehicles, fully realizing the trailer operation process. Monitoring sensors are installed in the brake lines to simulate accidents caused by improper brake hose connections.

[0035] The coupling device 500 is located between the two main frames 200. The coupling device 500 uses an automatic coupler; all couplers used on passenger and freight trains in my country are automatic couplers. An automatic coupler is one that automatically completes the coupling or uncoupling action when the coupler lever is pulled or when two cars collide. This type of coupler is characterized by a hook tongue on the coupler head that can rotate around the hook tongue pin, hence it is also called a joint coupler. The automatic coupler consists of three parts: the coupler head, the coupler body, and the coupler tail. The thicker front part is the coupler head, which contains the hook tongue, hook tongue pin, coupler lifting pin, hook tongue pusher, and coupler locking iron. The coupler tail is located at the rear of the coupler and has a vertical pin hole for connection to the coupler tail frame. Connecting the coupler head and the coupler tail is the slender coupler body.

[0036] Automatic couplers typically achieve smooth "handshake" and "separation" between train cars through three positions, also known as the "coupler three states." First, the locked position: the tail of the coupler tongue is fully engaged inside the coupler head, and the coupler lock inside the coupler automatically drops, blocking the tail of the coupler tongue and preventing it from turning outwards. After the vehicles are coupled, the couplers must be in the locked state, unable to pull apart, to ensure the transmission of locomotive traction. Second, the unlocked position: in this position, the coupler lock inside the coupler is raised, creating space at the bottom to allow the coupler tongue to turn freely. The unlocking methods differ between freight cars and buses; freight cars generally lift the coupler lock, while buses push it down. For two vehicles to "separate," one coupler must be in the unlocked position. Third, the fully open position, where the coupler tongue is fully extended. Before the vehicles are coupled, one coupler must be in the fully open position for automatic coupling to be achieved.

[0037] This device was designed based on the principle of interconnection for teaching purposes, allowing students to experience the on-site work environment firsthand, achieving 100% simulation. This greatly enhances students' interest in on-site work.

[0038] This device fully simulates the actual working conditions of coupling and uncoupling train couplers and ductwork on railways. Through practice with a series of real devices, students can fully meet the requirements of railway standards. Simultaneously, based on students' cognitive characteristics, the practical teaching content and methods are determined through extensive practice, progressing from easy to difficult, from single to comprehensive, and from emphasizing basic skills to mastering a range of job-related skills. This fosters students' passion for their major and future jobs, cultivates their ability to apply theoretical knowledge to practice, improves their practical skills, develops professional and job-related skills, and stimulates their creativity.

[0039] The main frame 200 is a rigid structure that forms a movable pushcart frame. It constitutes the movement and support of the entire cart, allowing it to move forward and backward on the guide rail.

[0040] Bogie 300: Small wheels similar in shape to locomotive wheels are used to represent the relationship between the wheels and the bogie. The bogie is one of the most important components in the structure of a rail vehicle. It is mainly used to support the car body, bear and transmit various loads and forces between the car body and the wheels or between the wheel and the rail and the car body, and to distribute the axle load evenly.

[0041] Power Structure 400: There is an electric motor on the solid frame to drive the entire trolley forward and backward. Through the current receiving device above, the current is introduced into the electric motor through the device. The movement of the movable parts is completed by the forward and reverse rotation of the electric motor, thereby realizing the coupling and uncoupling of the trolley and realizing a one-to-one restoration of the scene.

[0042] The emergence of railway locomotive and rolling stock coupling simulation teaching devices is of great significance to students majoring in railway locomotives. It plays a crucial role in ensuring the safe operation of railway trains, effectively reducing the probability of serious accidents caused by improper operation when engaging or disengaging brake hoses. The traditional single-coupler engagement and disengagement process is monotonous and lacks innovation. The railway locomotive and rolling stock coupling simulation teaching device offers a creative new model, allowing students to complete a series of operations and assessments in a realistic environment, increasing student enthusiasm and creativity, and stimulating their interest in learning.

[0043] A photoelectric sensor is installed on the track 100. The photoelectric sensor is fixed on the track 100 by a connecting plate and is used to detect the position of the main frame 200.

[0044] The coupling device 500 is equipped with a monitoring probe to record the coupling process for easy review and viewing later.

[0045] In actual use, the student controls the power mechanism 400 to work, which drives the main frame 200 to move on the track 100 through the bogie 300, so that the coupling device 500 can be connected and disassembled, simulating the real working situation.

[0046] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
