Embodiment 1

[0026] See attached figure 1 , the lock hook type hopper car bottom door secondary locking device provided by the present invention includes a lock hook 4, a lock body and a force applying unit, one end of the lock hook 4 is fixedly connected to the car body of the hopper car, and one end of the force applying unit is fixedly connected to the funnel The drive shaft of the bottom door of the car, the other end of the force applying unit is fixedly connected to the lock body; when the bottom door of the funnel car is in a closed state, the other end of the lock body is hooked by the lock hook 4 by means of the self gravity of the force applying unit; When the force unit exerts an upward force on the lock body, the lock body moves upward until the lock body reaches the critical position where it contacts the lock hook 4. If the force unit continues to apply an upward force to the lock body, the lock body breaks away from the lock. hook, the force applying unit drives the bottom d...

Embodiment 2

[0030] See attached figure 2 And attached image 3 The difference from the secondary locking device for the shackle-type hopper vehicle bottom door provided in Embodiment 1 of the present invention is that the secondary locking device for the shackle-type hopper vehicle bottom door provided in Embodiment 2 of the present invention also includes a connecting piece 2. In addition, the hook-type hopper bottom door secondary locking device provided in Embodiment 2 of the present invention provides a specific implementation of the force applying unit.

[0031] Wherein, the secondary locking device for the lock hook type funnel car bottom door also includes a connecting piece 2 through which the connecting block 3 of the lock hook 4 is connected to the car body 1 of the hopper car. Due to the complex structure of the funnel cart body 1, it is difficult to directly connect the lock hook 4 to the funnel cart body, but after using the connector 2, the lock hook 4 can be indirectly co...

Embodiment 3

[0040] See attached Figure 4 And attached Figure 5 , the difference from the secondary locking device of the shackle type funnel vehicle bottom door provided in the second embodiment of the present invention is that the force applying unit of the secondary locking device of the shackle type hopper vehicle bottom door provided in the third embodiment of the present invention It also includes an elastic part 16 and a stop part 25. There are two feet of the jacking mechanism, respectively 12 and 22. The stop part 25 is fixedly connected to the pin shaft 15 and is in the middle of the two feet 12 and 22. The roller 14 is arranged between the two feet 12, 22 and the stop member 25. One end of the elastic member 26 is against the waist 11 of the jacking mechanism, and the other end is against the stop member 25. When the pin shaft 15 is in the oblong hole 13 When the lower semicircle of , the elastic member 26 is in a natural state or a compressed state. Wherein, the function of...

Abstract

The invention discloses a lock hook type secondary locking device for the bottom door of a hopper car and a hopper car, belonging to the technical field of railway vehicles. The device includes a lock hook, a lock body and a force applying unit. One end of the lock hook is fixedly connected to the body of the hopper car, one end of the force applying unit is fixedly connected to the drive shaft of the bottom door of the hopper car, and the other end of the force applying unit is fixedly connected to the lock body. ; When the bottom door of the funnel car is in the closed state, the other end of the lock body is hooked by the lock hook with the help of the self gravity of the force applying unit; when the force applying unit exerts an upward force on the lock body, the lock body moves upward until After the lock body reaches the critical position where it is in contact with the lock hook, if the force applying unit continues to exert an upward force on the lock body, the lock body will break away from the lock hook, and the force applying unit will drive the drive shaft of the bottom door of the hopper car to rotate clockwise, and the hopper car will The bottom door opens. The device has high locking safety. The hopper car has the lock hook type hopper car bottom door secondary locking device, and the bottom door locking safety is high.

Description

technical field [0001] The invention relates to the technical field of railway vehicles, in particular to a hook-type secondary locking device for a hopper bottom door and a hopper bottom door. Background technique [0002] The opening and closing mechanism of the bottom door of the railway hopper car in the prior art usually adopts a double-armed broadsword opening and closing mechanism or a top lock opening and closing mechanism. Most of them have complex mechanisms, heavy weight, inconvenient operation, low efficiency, and maintenance costs. High, and prone to defects such as misoperation. [0003] There was once a "dead point self-locking" bottom door opening and closing mechanism. With the help of the "crossing dead point self-locking" bottom door opening and closing mechanism, the railway hopper car can unload the inside and outside of the track. The bottom door is opened and closed. The mechanism structure is simple, and it can realize unloading while walking, and th...
