Abstract

The invention relates to a bottom door opening-closing mechanism for a railway funnel type goods vehicle, which comprises a transmission shaft mounted on an underframe of a vehicle body. The mechanism is characterized in that two groups of double levers perpendicular to the transmission shaft are symmetrically fixed on the transmission shaft; a first connecting rod and a second connecting rod are respectively hinged to the two ends of each group of the double levers; the first connecting rods and the second connecting rods are respectively in hinged connection with bottom door compositions on the two sides of the transmission shaft; a door opening collision crank and a door closing collision crank are respectively fixed at the two ends of the transmission shaft; rollers are arranged at the end parts of the door opening collision crank and the door closing collision crank; and a secondary closing device is arranged at one end of the transmission shaft mounted with the door opening collision crank. The mechanism has the advantages that the structure is simple; the application is reliable; the maintenance is convenient; no extra motive power or manual operation is needed during the running process of the vehicle; a bottom door is fixed at a closing position; the automatic opening of the bottom door caused by the factors such as vibration is avoided; and the safety of the vehicle transportation is ensured.

Description

technical field [0001] The invention relates to an opening and closing mechanism for a bottom door of a railway funnel-type freight car, which belongs to the field of opening and closing control machinery for the bottom door of a railway funnel-type freight car. Background technique [0002] At present, the railway funnel trucks for bulk cargoes such as coal and ore are unloaded by using the dead weight of the cargo to unload from the unloading port at the bottom of the vehicle. [0003] According to the requirements of domestic ground facilities, this type of truck adopts longitudinal side opening to unload cargo. The unloading method can independently control the opening and closing of the bottom door of the vehicle through pneumatic and manual systems. Both the pneumatic operating platform and the manual transmission mechanism are located at one end of the car body, which can simultaneously operate the opening and closing movement of the unloading bottom doors on both sid...
