Touch-type bottom door opening and closing mechanism

Abstract

The invention relates to the technical field of railway vehicles, in particular to a touch-type bottom door opening and closing mechanism. The touch-type bottom door opening and closing mechanism comprises a touch arm mechanism, a transverse transmission shaft mechanism, a gearbox, a longitudinal transmission shaft mechanism, a first bottom door mechanism, a second bottom door mechanism, a first connection rod mechanism, a second connection rod mechanism, a transverse transmission shaft lifting base, a longitudinal transmission shaft lifting base and a gearbox lifting base; the transverse transmission shaft mechanism is fixedly connected with the touch arm mechanism; the input shaft of the gearbox is connected with the transverse transmission shaft mechanism; the output shaft of the gearbox is connected with the longitudinal transmission shaft mechanism; the first bottom door mechanism and the second bottom door mechanism are separately arranged on two sides of the longitudinal transmission shaft mechanism; the first bottom door mechanism is hinged to the longitudinal transmission shaft mechanism through the first connection rod mechanism; and the second bottom door mechanism is hinged to the longitudinal transmission shaft mechanism through the second connection rod mechanism. The touch-type bottom door opening and closing mechanism disclosed by the invention can be applicable to requirements of longitudinal opening and closing of a bottom door.

Description

technical field [0001] The invention relates to the technical field of railway vehicles, in particular to a touch-type bottom door opening and closing mechanism. Background technique [0002] At present, pneumatic and manual devices are mostly used to control the opening and closing of the bottom door of railway hopper cars. When unloading, it is necessary to manually operate the manual device or the pneumatic device to open and close the bottom door to complete the unloading of a single vehicle. The traditional air-controlled bottom door opening and closing mechanism needs to add a set of wind control system and driving air cylinder, its structure and operation are complicated, the degree of automation is not high, and the operating labor cost is high. The mechanical touch type bottom door opening and closing mechanism is adopted, and the unloading only needs to install the corresponding ground touch device on the ground to make the vehicle realize the function of unloading...
