Description

Railway rollover

Technical field

The invention relates to the technical field of railway freight cars, in particular to a railway side rollover.

Background technique

Railway side-turning vehicles are mainly used for transportation and side-loading of loose particles or block materials. Due to their comprehensive rail transportation and unloading to the outside of the track, they become the first choice for service vehicles for railway construction.

The body part of the railway self-propelled car is mainly composed of two parts, a chassis and a free-standing car. The car is used for loading materials. The actuator is mounted on the chassis, usually a cylinder or a cylinder, and the one side car is lifted simultaneously. The side door is opened to realize the function of unloading the rail side. At present, the self-turning vehicle with a load of 60T is the main type of freight vehicle on the railway in China.

Closed operation cylinder 4.1 top, side door opening and closing operation oil tank 4.1 bottom oil respectively through the balance valve module 7.15 cylinder bottom oil supply second interface and in turn through the cylinder bottom oil supply first interface, fourth check valve 7.13, three four The second oil outlet B of the valve 7.11 and the oil return port O of the three-position four-way valve 7.11 are directly returned to the hydraulic oil tank 7.16, and the piston rod of the side door opening and closing operation cylinder 4.1 is retracted, thereby driving the side door to close.

In case of emergency (the side door cannot be closed after the unloading operation at the unloading site), when the side door 3 is closed, the three-position four-way valve 7.11 to the closing position is operated (the three-position four-way valve 7.11 is in the middle position, that is, the first The oil outlet A and the second oil outlet B are connected to the oil return port O, and the oil inlet port P is closed. Then, the hand oil pump 7.14 is operated, and the oil is supplied to the first port of the cylinder and the top of the cylinder through the top of the balance valve module 7.15. The second port of the oil supply enters the top port of the side door opening and closing operation cylinder 4.1, and the bottom door opens and closes the oil at the bottom of the oil cylinder 4.1 through the balance valve module 7.15 cylinder bottom oil supply second interface and sequentially passes the oil cylinder bottom oil supply first interface The fourth check valve 7.13, the third oil outlet B of the three-position four-way valve 7.11, the oil return port O of the three-position four-way valve 7.11 directly return to the hydraulic oil tank 7.16, at which time the cylinder piston rod is retracted, thereby driving the side door shut down. As shown in Figure 5. It can be realized in the case of system failure (ie, opening solenoid valve 7.1, closing solenoid valve 7.2, manual valve 7.3, three-position reversing valve 7.4, gas source module 7.7, gas-liquid conversion module 7.10, three-position four-way valve 7.11 or synchronization) The motor fuel supply module 7.12 fails, and the side door is closed to ensure the safety of the line trailer.
