Problems solved by technology

The above road-rail dual-purpose driving platforms are mainly used for manual traction operations, have certain mobility, and the railway driving speed is low (20-30km / h), which is not suitable for rapid rescue and unmanned driving platform applications
When switching between highways and railways, it mainly relies on manual work. If accurate positioning cannot be achieved, alignment needs to be repeated many times. The alignment time is long and the efficiency is low.
Moreover, the above-mentioned road-rail dual-purpose driving platform is mainly switched at level crossings, and the line environment at other positions on the track cannot be switched smoothly.
In addition, its driving methods are all operated by manual driving. However, when driving manually, the environmental speed limit conditions such as different curves cannot be accurately controlled, and it is easy to overturn and have low reliability. Therefore, this road-rail dual-purpose driving platform When driving on the railway, there is a strict speed limit. Generally, the speed limit is within 45km / h, and the daily use is mostly within 30km / h.
In addition, the road-rail dual-purpose driving platform is heavy, and it cannot carry heavy equipment under road tire driving conditions

Embodiment 1

[0051] Figure 1 to Figure 6 A preferred embodiment of a railway intelligent multifunctional traveling platform according to the present invention is shown. As shown in the figure, the railway intelligent multifunctional traveling platform includes a traveling platform main body 1 and a lifting and rotating mechanism 4 located at the bottom of the traveling platform main body 1 and connected with the traveling platform main body 1 . This railway intelligent multifunctional driving platform also includes a track wheel drive system 3 and a crawler belt drive system 2 that are respectively connected with the drive platform main body 1, wherein the track wheel drive system 3 is used for driving on the track 6, and the track drive system 2 is used for running on the track 6. Driving on roads, wet dirt roads, etc.

[0052] When in use, first drive the intelligent multifunctional railway platform vertically on the track 6 through the crawler drive system 2 to the longitudinal direct...

Embodiment 2

[0102] This embodiment is basically the same as Embodiment 1. For the sake of brevity, in the description process of this embodiment, the same technical features as Embodiment 1 will not be described, and only the differences between this embodiment and Embodiment 1 will be described:

[0103] Such as Figure 20 to Figure 22 As shown, in this embodiment, the rail wheel drive system 3 is rotationally connected with the traveling platform main body 1 through the rotating mechanism 8, and the crawler belt driving system 2 remains stationary relative to the traveling platform main body 1, so that the bottom of the crawler belt driving system 2 is higher than Or lower than the bottom of the track wheel drive system 3, thereby realizing the switching of the track drive system 2 and the track wheel drive system 3.

[0104] Specifically, the track wheel drive system 3 includes a front track wheel drive unit and a rear track wheel drive unit respectively located at the front end of the...

Abstract

The invention relates to the technical field of traffic, in particularly to a method for ascending and descending an intelligent multi-functional driving platform for railways on a track. The method comprises a track-ascending mode and a track-descending mode. The track-ascending mode comprises the step 11: through a driving system for road driving, a driving platform body is vertical to the trackvertical direction and driven to the center of the track; step 12, an elevating rotary mechanism stretches downwardly in order to lift the driving platform body to a certain height, the driving platform body rotates 90 degrees such that track wheels are aligned with a rail; step 13, the driving system for road driving ascends relative to a track wheel driving system such that the bottom of the driving system for road driving is higher than the bottoms of the track wheels, and descending the driving platform body through the elevating rotary mechanism in order to finish switching; step 14, lifting the elevating rotary mechanism. The intelligent multi-functional driving platform for railways can automatically switch between the track wheel driving system and a crawler belt driving system. Therefore, the intelligent multi-functional driving platform for railways can be ascended and descended from the track under intelligent control.

Description

technical field [0001] The invention relates to the technical field of railway equipment, in particular to a method for getting on and off the track of a railway intelligent multifunctional driving platform. Background technique [0002] The dual-purpose technology of highway and railway at home and abroad is mainly used for railway traction, which can realize fast switching between different railway lines. Foreign countries are represented by the Unimog road-rail vehicles of the American Tramobi Company and German Mercedes-Benz, and the domestic road-rail vehicles of Harbin Railway Bureau Internal Combustion Machinery Factory and Dalian Tiefeng United Technology Co., Ltd. to represent. The above road-rail dual-purpose driving platforms are mainly used for manual traction operations, have certain mobility, and the railway driving speed is low (20-30km / h), which is not suitable for rapid rescue and unmanned driving platform applications. When switching between highways and ...
