Embodiment 1

[0021] Below in conjunction with the first switch door arm 7 is arranged on the left side of the car body, and the second switch door arm 8 is arranged on the right side of the car body. The working principle of the bottom door opening and closing mechanism provided by the present invention is described in the embodiment in which the door opening handle of the first switch door arm 7 and the second door switch arm 8 are at the front and the door closing handle is at the back.

[0022] When one end of the vehicle is running ahead, the touch platform for opening the door on the ground is arranged on the left side of the track, that is, the touch platform for opening the door on the ground is on the same side as the first switch door arm 7 . The bottom door is opened in the following manner: the door opening handle 7a of the first switch door arm 7 collides with the door opening touch table, the door opening handle 7a of the first switch door arm 7 rotates clockwise, and drives th...

Embodiment 2

[0025] Below in conjunction with the first switch door arm 7 is arranged on the left side of the car body, and the second switch door arm 8 is arranged on the right side of the car body. The working principle of the bottom door opening and closing mechanism provided by the present invention will be described in the embodiment in which the closing handle of the first opening and closing door arm 7 and the first opening and closing door arm 8 are at the front and the door opening handle is at the rear. In this embodiment, compared with Embodiment 1, the direction of the double-link lever in Embodiment 1 can be adjusted by 180 degrees. Then, compared with Embodiment 1, the direction of the four-link cross-dead point will be changed, thereby affecting the first switch door arm 7 and the direction in which the first switch door arm 8 switches the door handle to rotate.

[0026] When one end of the vehicle is running ahead, the touch platform for opening the door on the ground is ar...

Abstract

The invention discloses a bottom door opening and closing mechanism which comprises a transmission shaft, a double-connection lever, a first connection rod, a second connection rod, a first door opening and closing arm, a second door opening and closing arm and a bottom door. The transmission shaft is fixedly connected with a car frame, the double-connection lever is installed on the transmission shaft, one end of the first connection rod and one end of the second connection rod are hinged to the double-connection lever, the other end of the first connection rod and the other end of the second connection rod are hinged to the corresponding outer side of the bottom door. One side of the bottom door is hinged to the bottom of a hopper car. The first door opening and closing arm and the second door opening and closing arm are installed at two ends of the transmission shaft respectively. The bottom door, the first connection rod, the second connection rod and the double-connection lever form a four connection rod mechanism. The first door opening and closing arm and the second door opening and closing arm rotate clockwise or anticlockwise to drive the first connection rod, the second connection rod and the double-connection lever to remove to achieve opening or closing of the bottom door accordingly. A bottom door opening and closing system is further provided. The bottom door opening and closing mechanism can solve the problem that wheel sets on one single side are severely abraded.

Description

technical field [0001] The invention relates to the technical field of hopper cars, in particular to a bottom door opening and closing mechanism. Background technique [0002] The railway hopper car is mainly used for the transportation of bulk grain, gravel, coal and other bulk goods. When unloading, the bulk goods will automatically flow out of the bottom door of the hopper car by its own gravity. Its transportation quality is high, and the loading and unloading time can be shortened. Accelerate vehicle turnover, improve loading and unloading labor conditions, and reduce transportation costs. The opening and closing mechanism of the bottom door is the key component to ensure the normal unloading of railway hopper cars. The bottom door is not opened normally due to other factors. The current bottom door closing mechanism continuously increases the eccentric wear of the single side wheel set, which greatly reduces the life of the wheel, not only increases the cost of vehic...
