Description

Dual-purpose vehicle for highway and railway

The invention relates to the description of vehicle, particularly the description that the dual-purpose vehicle for highway and railway of usefulness is rescued in railway rifle danger.

Past, the disclosed dual-purpose vehicle for highway and railway of British patent (2052406) particularly, it is by the chassis, driving engine, the front and back highway wheel, front and back railway wheel and first, second actuating device is formed, when this car moves on highway, on highway wheel falls, vehicle wheel load-bearing by road, when on railway, moving, highway wheel rises and does not contact with track, the weight of vehicle is born by railway wheel, and the drive ability of vehicle is also undesirable, and this car is from the operation of highway to railway, requirement is at level crossing, a goods yard or produce or utilize on the inclined-plane and carry out receives certain condition restriction.And for example US Patent (4448132) is disclosed has the dual-purpose bogie device of highway wheel and railway wheel and the rail-road car that a pair of axle device that promotes is formed by one, if this car owner is constant in order to guarantee to make the load-carrying of vehicle from the railway operation to the highway, be suitable for heavy haul transport, and this car is operated inconvenience, is involved great expense.

Task of the present invention will provide a kind of rail-road car exactly, have the utilization flexible, reliable, easy to operate, cost is low, drive ability good, the characteristics of being convenient to keep in repair.

Main points of the present invention are that it is a autotruck based on public use, make it adapt to the railway standard gauge to the tired wheel on the same axle apart from reequiping, and before adding, rear guide wheel device, central rotating-disk unit, bearing circle locking device, gear type pump, petrol storage tank, siren horn, headlight, back light, hitch and hydraulic lift, preceding, rear guide wheel device, central rotating-disk unit and before, two hydraulic lifting oil cylinders correspondingly are housed on the rear pneumatic tyre unit, to promote and to fall these devices, the operating console of whole hydraulic efficiency gear is located in the driver's cab, is controlled by the driver.

Dual-purpose vehicle for highway and railway of the present invention can fully selectively utilize the characteristics operation of highway and railway, for the rescue and the railway transportation of railway good effect is arranged all.From the rescue of rifle danger, it can not take railway line or take railway line less and arrive the scene of the accident, carry out the work of rescuing of answering of rolling stock with the supporting use of Porto Power, and can transport the goods and materials and the wounded, reduce causality loss, reduce character of accident, shorten rescue time, also can replace locomotive, vehicle towed near station with after rescuing again; From the transportation aspect, use this car in departments such as electricity affair, worker's affair, line bridge projects, can solve the difficulty that small-sized rail vehicle busy line brings to transportation-production, in addition, combined car AT STATION, the turnover that can also improve vehicle of factory, mine, the timely marshalling of vehicle, decomposition etc., the factory, enterprise, mine, oil field etc. that private siding arranged be arrival and transporting timely, increases work efficiency greatly and economic benefit.Add this car and carry out improvement and design under the condition that does not increase driving engine, it is abundant to make the source, and popularizing value is arranged very much.

The present invention is described further by accompanying drawing below.
