Problems solved by technology

Therefore, the bottom door mechanism using the lap seal must add an additional power device to control the closing sequence of the two bottom doors, and at the same time, corresponding components must be added to the control system of the power device to realize the connection between the two bottom doors. closing sequence, so that the structure of the bottom door device is too complicated and the manufacturing cost is high

Abstract

The invention provides a bottom door device and a hopper car. The bottom door device is provided with a first bottom door and a second bottom door, wherein the first bottom door is provided with a first door end plate and a first bottom door plate which are welded and fixed; the second bottom door is provided with a second door end plate and a second bottom door plate which are welded and fixed; and the first bottom door plate and the second bottom door plate are subjected to labyrinth seal. In the bottom door device and the hopper car which are provided by the invention, the labyrinth seal is adopted to replace the lap joint seal in the prior art, the requirement of tightness still can be satisfied on the premise that the two bottom door plates do not have a closing sequence, and the structure of the traditional bottom door device is optimized.

Description

technical field [0001] The invention relates to the structure of a hopper car, in particular to a bottom door device and a hopper car. Background technique [0002] The hopper car is a bottom-opening vehicle, which is used to transport bulk cargo. After the vehicle arrives at the destination, the bulk cargo is unloaded by bottom unloading. [0003] Due to the long transportation mileage and large vibration, the sealing performance of the bottom door device is very important when using the bottom door vehicle to transport valuable and powdery bulk goods. If the sealing performance is not good, the goods will leak and cause economic losses, and the environment will be polluted and the lives of relevant personnel will be endangered. [0004] Figure 1a It is a structural schematic diagram of the bottom door device of the hopper car in the prior art, which shows the closed state, Figure 1b for Figure 1a Partial enlarged schematic diagram of I. The bottom door device has a s...
