Abstract
The utility model provides a traveling wheel switching lifting device of a rail-road car. According to the traveling wheel switching lifting device of the rail-road car, an oil cylinder is arranged above a lifting device used for traveling wheel switching of the rail-road car, and the lower end of the oil cylinder is connected with an overturning frame through an overturning wheel. When the traveling wheel switching lifting device of the rail-road car is used, the overturning frame can be driven to overturn under the hydraulic action of the oil cylinder to enable a wheel set to rise or descend quickly, and then the switching of traveling wheels on the bottom of the rail-road car is achieved, and control and operation are convenient and fast.
Description
Technical field
The utility model relates to a kind of shifter of road rail vehicle road wheel, and a kind of road rail vehicle road wheel switches jacking system specifically.
Background technology
The vehicle that travels on the railway at present is all take guideway vehicle as main, in recent years for convenient transportation, the combined vehicle that can travel but also can travel in orbit at highway has appearred not only, this road rail vehicle cardinal principle is in under-vehicle rail wheel and rubber wheel to be set simultaneously, during use, different rows travelling wheel with the below switches as required, because load-carrying and the deadweight problem of dual-purpose vehicle, the switching lifting of road wheel bothers very much, so far still without a kind of easily and fast, practical jacking system.
Summary of the invention
The utility model is to provide a kind of road rail vehicle road wheel to switch jacking system, can fast, easily road wheel be carried out lifting by hydraulic principle and switch.
The utility model comprises oil cylinder, and the specific implementation method that adopts is as follows:
Above a jacking system that mutually switches for the road rail vehicle road wheel, an oil cylinder is set, is connected with the turning rack that is used for road wheel upset switching by turning wheel in the oil cylinder lower end.During use, by the hydraulic action of oil cylinder, the switching of realization road wheel that can turning rack.
In the technique scheme: described turning wheel is fixed in the middle of the trip shaft of turning rack.
The oil cylinder lower end adopts bearing pin and turning wheel to be flexibly connected.
The beneficial effects of the utility model are: by above-mentioned a kind of like this structure, owing to will adopt oil cylinder as propulsive effort for the jacking system that the road rail vehicle road wheel switches, and adopt turning wheel to connect the mode that trip shaft is realized turning rack, during use, only need to start oil cylinder, can realize easily by the hydraulic action of oil cylinder the lifting switching of road wheel by turning rack, efficiently solve present road rail vehicle road wheel and switch trouble and inconvenient problem, scientific structure operates easy and convenient.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, oil cylinder, 2, bearing pin, 3, turning wheel, 4, trip shaft, 5, turning rack.
The specific embodiment
Shown in Figure 1: above a jacking system that switches for the road rail vehicle road wheel oil cylinder 1 is arranged, this oil cylinder 1 lower end is connected with turning rack 5 by turning wheel 3.Turning wheel 3 is fixed in the middle of the trip shaft 4 of turning rack 5.Oil cylinder 1 lower end adopts bearing pin 2 and turning wheel 3 to be flexibly connected.
Claims (3)
