Description

Technical Field

[0001] The invention relates to the technical field of cruise equipment, in particular to a composite power switching type rail-hung tram. Background Art

[0002] In the field of rail transportation, the trolley, as a unique means of transportation, has broad application prospects in specific scenarios. It relies on the rail system to operate. Compared with traditional ground transportation methods, it has the advantages of flexible route planning, small footprint, and less impact on the environment. It is widely used in industrial production and warehousing environments. Automatic cruise trolleys are widely used in various industrial and logistics applications. They can be used for raw material supply, delivering raw materials from storage areas or supply areas to production lines. In addition, they can also be used for product distribution, delivering finished products from the production line to the warehouse or transporting them to the next production stage. In a manufacturing environment, they can also be used to support assembly lines and provide operators with the parts and tools they need.

[0003] There are still many technical defects in the existing hanging rail tram equipment. In terms of the power system, the power switching mechanism of most traditional hanging rail trams is not perfect. For example, when facing track conversion with different road conditions, such as switching from a straight track to a climbing track, the consistency and stability of power transmission are poor, which makes them prone to collision risks in application scenarios that require turning or climbing. Some existing designs are difficult to adjust the power output stably, resulting in fluctuations in power supply during the climbing process, and unable to continuously and stably provide sufficient driving force for the vehicle, which is easy to cause the vehicle's climbing speed to be unstable, and even stagnate due to insufficient power when the slope is large, seriously affecting transportation efficiency and operational reliability. In addition, at the curved track, the existing tram drive often lacks flexibility and precision, because they cannot achieve precise turning and may collide with obstacles standing on the path. Traditional trams with a single drive are prone to slipping when switching paths such as climbing, because only one wheel or wheel group provides power, and the other wheels may lose traction. This not only affects the transportation efficiency of the tram, but may also cause equipment damage or dangerous situations, or even deviate from the track, especially at high speeds or in emergencies. This not only causes problems for the operation of the tram itself, but may also cause damage to the environment and other equipment. Summary of the invention

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. In terms of power transmission and track adaptability, its innovative power drive structure and the power switching structure designed specifically for different tracks play a key role. Taking the climbing track as an example, the climbing power switching structure shows excellent performance. When the tram approaches the climbing track, the climbing drive rotating rod can accurately cooperate with the climbing auxiliary rotating rod under the action of the climbing push seat, and the power can be smoothly transmitted from the power auxiliary rod to the climbing drive rotating rod through the transmission connection between the outer roller and the winding drive belt. The meshing of the climbing drive spur gear and the climbing auxiliary spur gear further ensures the effective conversion and amplification of power, thereby providing a strong and stable power source for the climbing power spur gear. The close cooperation with the climbing gear plate allows the tram to continuously and stably obtain sufficient power during the climbing process, effectively avoiding the problem of insufficient or fluctuating power, ensuring the uniformity and stability of the climbing speed, greatly improving the reliability and efficiency of climbing, enabling the tram to cope with the challenges of climbing with various slopes, and significantly expanding its operational terrain range.

[0018] 2. In terms of operational stability, the cooperation between the guide plates and guide wheels on both sides of the cruise car and the guide rails on the track provides reliable guidance and stable support for the tram during operation. Whether it is high-speed driving during straight driving or under complex working conditions during track conversion, it can effectively limit the shaking and deviation of the vehicle body to ensure that the tram always runs stably along the predetermined track. At the same time, the design of the climbing stability structure and the cornering stability structure further enhances the overall stability. After the climbing or cornering operation is completed, the climbing stability plate and the climbing compression spring, the cornering stability plate and the cornering compression spring can quickly and accurately return the relevant components to their positions, preparing for the next track conversion or continuous operation, reducing the operational instability factors caused by component position deviation, reducing the failure rate and maintenance requirements of the equipment, and improving the overall service life and operational reliability of the equipment, providing passengers with a safer and more comfortable riding experience, and also laying a solid foundation for the large-scale application of hanging rail trams in more scenarios.

[0019] 3. Using only a single servo motor greatly simplifies the system structure, reduces the number and complexity of components, reduces the number of motors and related controllers required, and reduces not only the initial investment cost, but also the cost of operation and maintenance. A single servo motor can achieve a more compact device design and save space. This is especially important for application scenarios that require operation or movement in a limited space.

A climbing compression spring 92 is fixed to the side wall of the climbing stabilizing plate 91. The other end of the climbing compression spring 92 is in contact with the outer wall of the track.

[0038] The working principle of the present invention is as follows:

[0039] Straight-moving state: the servo motor 51 drives the power rod 52 to rotate, and the cooperation of the three straight-moving driving spur gears 54 drives the main driving rotating rod 3 to rotate, and then drives the traveling wheel 4 to rotate, so that the cruise vehicle 1 operates as a whole, and the cruise vehicle 1 moves smoothly on the straight-moving track 21. When the cruise vehicle 1 moves, the guide wheel 11 rolls on the side of the guide rail 12, further improving the stability of the operation of the cruise vehicle 1.

[0040] Turning state: when the cruise vehicle 1 gradually approaches the turning track 22, the turning auxiliary rotating rod 61 gradually approaches the turning pushing seat 69. When the turning auxiliary rotating rod 61 contacts the inclined surface of the turning pushing seat 69, the turning auxiliary rotating rod 61 gradually moves toward the turning outer frame 611. At this time, the turning compression spring 82 is gradually compressed, and the turning power spur gear 64 gradually meshes with the turning pre-engaging hobbing gear 610 to achieve pre-adjustment of the turning power spur gear 64. Subsequently, the turning power spur gear 64 can be more stably connected with the turning hobbing gear 66. When the turning auxiliary rotating rod 61 moves to the position where the turning pushing seat 69 is closest to the track, the turning drive spur gear 65 and the power rod 52 are connected. The straight driving spur gear 54 is meshed with the bevel gear 1 67 and the bevel gear 2 68. At this time, the rotation of the servo motor 51 will drive the turning driving spur gear 65 to rotate, and then drive the bevel gear 1 67 to rotate through the turning auxiliary rotating rod 61, and drive the turning connecting rod 63 to rotate through the cooperation of the bevel gear 1 67 and the bevel gear 2 68, so that the turning power spur gear 64 rotates. Through the cooperation of the turning power spur gear 64 and the turning hobbing 66, a stable turning power is provided for the cruise vehicle 1, and the turning process is guided to achieve stable turning of the cruise vehicle 1. After the turning process is completed, the rebound of the turning compression spring 82 drives the turning auxiliary rotating rod 61 to return to its position, and the cruise vehicle 1 can continue to go straight.

[0041] Climbing state: when the cruising vehicle 1 gradually approaches the climbing track 23, the climbing driving rotating rod 71 gradually approaches the climbing pushing seat 79. When the climbing driving rotating rod 71 contacts the inclined surface of the climbing pushing seat 79, the climbing driving rotating rod 71 gradually moves in the direction away from the climbing pushing seat 79. At this time, the climbing compression spring 92 is gradually compressed, and the climbing power spur gear 76 gradually meshes with the rolling teeth of the climbing pre-meshing tooth plate 714, and the climbing connecting spur gear 711 gradually meshes with the rolling teeth of the climbing connecting seat 712, so as to realize the pre-adjustment of the climbing power spur gear 76. Subsequently, the climbing power spur gear 76 can be more stably connected with the rolling teeth of the climbing tooth plate 78. When the climbing driving rotating rod 71 moves to the position where the climbing pushing seat 79 is closest to the track, When the servo motor 51 drives the power rod 52 and the power auxiliary rod 53 to rotate, the climbing auxiliary rotating rod 72 is driven to rotate through the transmission belt 73. Therefore, the climbing auxiliary spur gear 75 will drive the climbing driving spur gear 74 to rotate, and then drive the climbing power spur gear 76 to rotate through the climbing driving rotating rod 71. The cooperation of the climbing power spur gear 76 and the climbing tooth plate 78 provides the cruise vehicle 1 with stable climbing power. The cooperation of the climbing connecting spur gear 711 and the climbing connecting seat 712 further improves the stability of the climbing process. After the climbing process is completed, the rebound of the climbing compression spring 92 drives the climbing driving rotating rod 71 to return to its position, and the vehicle can continue to go straight.
