Integrated controlled convertible car for railroads and roads

Abstract

The invention provides an integrated controlled convertible car for railroads and roads. The integrated controlled convertible car comprises a car frame, wheels 2, guide wheels 3, an aerial work platform 6, an electronic control unit 4and a hydraulic unit 5, wherein the wheels are arranged on the car frame; the guide wheels are connected to the car frame 1 by a lifting frame; a lifting oil cylinder 31 is arranged between the lifting frame and the car frame 1; the aerial work platform 6 comprises a rotary platform 61, a base 62, a telescopic arm 63, a folding arm 64, a drive oil cylinder 65 and a working bucket 66; the hydraulic system comprises an oil tank 51, a variable plunger pump 52 and two load-sensitive multiway valves 53; load-induction oil paths of the two load-sensitive multiway valve are connected with a load sensitive valve of a variable plunger pump by a shuttle valve; the load-sensitive multiway valves and the variable plunger pump are respectively connected with the electronic control unit by a controller area network (CAN) bus; a lifting oil cylinder is connected with one of the load-sensitive multiway valves; and the drive oil cylinder is connected with another load-sensitive multiway valve, so that the integrated control of the convertible car for railroads and roads is realized, and the reliability of the convertible car is improved.

Description

technical field [0001] The invention relates to a dual-purpose railway and highway vehicle, in particular to an integrated control type dual-purpose railway and highway vehicle. Background technique [0002] At present, dual-purpose vehicles for railway and road are widely used in the rail transportation industry because they can run on both roads and railways. Dual-purpose vehicles for railway and road are usually used for railway traction, emergency repair, construction and emergency rescue operations. . Most of the dual-purpose vehicles for railway and highway in the prior art are simply adding railway guide wheels and aerial work platforms on the original automobile chassis, and then controlling the lifting of railway guide wheels and the action of aerial work parts by relays. The electrical systems of various parts of the dual-purpose railway vehicle are independent of each other and are all controlled by relays. The integration level is low and the system reliability ...
