Description

Technical Field

[0001] The invention relates to the technical field of rail transportation, in particular to a suspended monorail transportation system with strong climbing ability. Background Art

[0002] Suspended monorail is a ground transportation tool in which the train runs suspended in the air. It does not occupy the right of way of ground public transportation and is relatively convenient to build and construct. It can effectively alleviate the congestion problem faced by urban transportation.

[0003] Traditional suspended monorail trains use motors to drive the running wheels, which rely on the adhesion between the running wheels and the track beams to achieve traction and running. The running wheels bear the weight of the entire vehicle. Due to the limited motor power and the adhesion between the tires and the track beams, the climbing ability of the suspended monorail train is limited. The maximum longitudinal slope that the suspended monorail train can pass is about 60‰. Therefore, the suspended monorail train cannot be promoted under conditions of larger slopes, such as environments with large road undulations such as mountainous areas. This has limited the scope of application of the suspended monorail transportation system to a certain extent. Summary of the invention

[0004] The purpose of the present invention is to provide a suspended monorail transportation system with strong climbing ability to address the problem that traditional suspended monorail trains in the prior art drive running wheels with motors and rely on the adhesion between the running wheels and the track beams to achieve traction running. Due to the limited motor power and the adhesion between the tires and the track beams, the climbing ability of the suspended monorail trains is limited.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] A suspended monorail transportation system with strong climbing ability comprises a track beam, a bogie frame, a vehicle body suspended below the bogie frame, running wheels and guide wheels arranged on the bogie frame, a suspension device is provided on the inner side of the track beam, and the bogie frame is provided with a rolling device, the suspension device is adapted to the rolling device, and the rolling device can run along the suspension device.

[0007] Since the inner side of the track beam described in the present invention is provided with a suspension device, the bogie frame is provided with a rolling device, the suspension device is adapted to the rolling device, and the rolling device can run along the suspension device, when the suspended monorail train is traveling on a steep slope section, the steep slope section refers to a section with a slope greater than 60‰, and the rolling device can roll on the suspension device. In this way, the suspended monorail train can not only rely on the running wheels to run along the span direction of the track beam, but also rely on the rolling device to run on the suspension device, which greatly increases the adhesion and traction of the suspended monorail train, effectively improves the climbing ability of the suspended monorail train, and can climb longitudinal slopes with a slope greater than 60‰, thereby broadening the application field of the suspended monorail transportation system, reducing the impact of mountainous terrain, and increasing the range of choices for mountain railway track transportation systems.

[0008] Furthermore, when the suspended monorail train travels on a steep slope section, the tire wear of the running wheels and the guide wheels will increase. The design of the suspension device and the rolling device can also extend the service life of the tires and reduce operation and maintenance costs.

[0009] As a preferred embodiment of the present invention, the rolling device is arranged on the top of the bogie frame. When the rolling device is arranged on the top and used in conjunction with the suspension device, it can share the weight borne by the running wheels, increase the adhesion traction of the suspended monorail train, and is also easy to install.

[0010] As a preferred embodiment of the present invention, the suspension device includes a steel cable support frame and a steel cable, one end of the steel cable support frame is connected to the inner side of the track beam, and the other end of the steel cable support frame is provided with the steel cable, and the length direction of the steel cable is the same as the span direction of the track beam; the rolling device includes a grooved wheel, and the grooved wheel can roll on the steel cable.

[0011] When the suspended monorail train travels on a line section with a large slope, the grooved wheels can roll on the steel cables. In this way, the suspended monorail train can not only rely on the running wheels to run along the span direction of the track beam, but also rely on the grooved wheels to run on the steel cables, which greatly increases the adhesion and traction of the suspended monorail train and effectively improves the climbing ability of the suspended monorail train.

[0012] As a preferred embodiment of the present invention, the suspension device further comprises a bracket connection seat and a steel cable support seat, the steel cable support frame is connected to the inner guide surface of the track beam via the bracket connection seat, and the steel cable support frame is connected to the steel cable via the steel cable support seat. The bracket connection seat is first arranged on the inner guide surface of the track beam to facilitate the installation of the steel cable support frame and the steel cable.

[0013] As a preferred embodiment of the present invention, each of the suspension devices includes a plurality of the bracket connecting seats, the steel cable support frames and the steel cable support seats. The bracket connecting seats, the steel cable support frames and the steel cable support seats are arranged at intervals along the span direction of the track beam, thereby ensuring the load-bearing capacity and strength of the steel cable.

[0014] As a preferred embodiment of the present invention, the rolling device also includes a grooved wheel arm and an actuating device, one end of the grooved wheel arm is connected to the grooved wheel, the other end of the grooved wheel arm is connected to the actuating device, the actuating device is connected to the bogie frame, and the actuating device is used to drive the grooved wheel arm to move, so that the grooved wheel arm drives the grooved wheel to move onto the steel cable.

[0015] When the suspended monorail train runs on a straight line section or a line section with a small slope, the guide surface inside the track beam is not provided with a suspension device, and at this time, the running wheels realize traction running in the span direction of the track beam, and the rolling device is in a non-working state;

[0016] When the suspended monorail train is about to run from a flat straight section or a small slope section to a large slope section, the actuating device starts to work, driving the grooved wheel to move upward into the installation area of ​​the suspension cable device, that is, the grooved wheel is located directly above the steel cable, and then the actuating device drives the grooved wheel to move downward and clamp on the steel cable, so as to fit tightly;

[0017] When the suspended monorail train runs on a line section with a large slope, the inner guide surface of the track beam is provided with the suspension cable device, so that in addition to the running wheels realizing traction running in the span direction of the track beam, the grooved wheels also run along the steel cables, and the two work together to realize the traction running of the suspended monorail train, which greatly increases the adhesion traction force of the suspended monorail train, and thus can climb a longitudinal slope with a gradient greater than 60‰.

[0018] As a preferred solution of the present invention, the actuating device is a hydraulic actuator or an electric actuator, and the actuating device drives the grooved wheel arm to move in a vertical direction, so as to drive the grooved wheel to move above the steel cable.

[0019] As a preferred solution of the present invention, the suspension device is arranged on the track beam with a large slope. In a straight line section or a small slope section, the suspension device is not arranged on the inner side of the track beam, and the track beam can be moved along the span direction of the track beam only by the running wheels, while the suspension device is arranged on the large slope section, which can save costs and does not require full line coverage. The small slope section refers to a section with a slope less than or equal to 60‰, and the large slope section refers to a section with a slope greater than 60‰.

[0020] As a preferred embodiment of the present invention, an air spring and a shock absorber are further provided between the bogie frame and the car body to filter the bumps generated by the car body during operation, with light vibration and low noise, thereby improving the riding comfort of passengers.

[0021] As a preferred embodiment of the present invention, the running wheels are arranged in pairs, and the two running wheels in a pair are installed on the same gear box. The suspended monorail transportation system with strong climbing ability also includes a running wheel drive motor, and the running wheel drive motor is used to drive the gear box and then drive the running wheels to rotate.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] Since the inner side of the track beam described in the present invention is provided with a suspension device, the bogie frame is provided with a rolling device, the suspension device is adapted to the rolling device, and the rolling device can run along the suspension device, when the suspended monorail train is traveling on a steep slope section, the steep slope section refers to a section with a slope greater than 60‰, and the rolling device can roll on the suspension device. In this way, the suspended monorail train can not only rely on the running wheels to run along the span direction of the track beam, but also rely on the rolling device to run on the suspension device, which greatly increases the adhesion and traction of the suspended monorail train, effectively improves the climbing ability of the suspended monorail train, and can climb longitudinal slopes with a slope greater than 60‰, thereby broadening the application field of the suspended monorail transportation system, reducing the impact of mountainous terrain, and increasing the range of choices for mountain railway track transportation systems.
