Description

Technical Field

[0001] The utility model belongs to the technical field of traction devices, and particularly relates to a traction device for a large-gradient rack railway train. Background Art

[0002] Existing sightseeing trains are mainly ground sightseeing vehicles. Due to the limitation of ground roads, sightseeing passengers can only enjoy the surrounding scenery from a horizontal perspective, resulting in a poor tourism sightseeing experience. If you want to overlook the scenic spots from a high altitude, you need a high viewing platform or take high-altitude lifting equipment such as helicopters or hot air balloons. The high viewing platform is restricted by its location and cannot offer a panoramic view; while taking high-altitude lifting equipment such as helicopters or hot air balloons is expensive, with a short experience time and not suitable for large numbers of tourists to experience. Moreover, it is difficult to experience a panoramic view in urban tourist attractions. Therefore, the rack railway sightseeing train emerged. The rack railway sightseeing train is a new type of tourism transportation method, which has the characteristics of strong climbing ability, low line construction cost, and short construction period.

[0003] However, at present, no rack railway train traction device with a gradient up to 50% has been found, so optimization and improvement are needed. Summary of the Utility Model

[0004] Aiming at the problems raised in the above background art, the purpose of the present utility model is to provide a traction device for a large-gradient rack railway train.

[0005] To achieve the above technical purpose, the technical solution adopted by the present utility model is as follows:

[0006] A traction device for a large-gradient rack railway train, comprising a track mechanism and a traction mechanism installed on the track mechanism. The track mechanism includes a number of columns, on which a support beam is installed. Two tracks are installed in parallel on the top of the support beam, and a rack is installed at the bottom of the track.

[0007] The traction mechanism includes a drive frame installed between the two tracks. An upper core disc is installed on the top of the drive frame. A load-bearing guide wheel is installed on the drive frame above the track, and a drive guide wheel is installed on the drive frame below the track. A drive motor is installed on the drive frame, and a drive gear connected to the output end of the drive motor is installed on the drive frame. The drive gear meshes with the rack.

[0008] Further defined, the drive motor is equipped with an electromagnetic brake. Such a design is an ideal automation execution element in modern industry and can play roles such as transmitting power and controlling motion in a mechanical transmission system.

[0009] Further defined, the drive frame is installed with a guide arm and a traction box assembly. Such a design is conducive to guiding and docking installation.

[0010] Further limitation: The drive motor is a KA reducer. With such a design, the KA reducer uses bevel gear transmission and has a vertical output, featuring a compact structure and low noise.

[0011] Further limitation: At least two load-bearing guide wheels are installed at both ends of the drive frame. With such a design, the load-bearing effect and the moving guiding ability are ensured.

[0012] Advantages of adopting the present utility model:

[0013] With the structural design of the present utility model, through practical verification, the structure is reliable, the impact is small, and the traction power and safety of the steep-gradient rack train are greatly improved; furthermore, it is also applicable to sightseeing trains with multiple power sources.
