Problems solved by technology

The realization of this scheme is based on the transformation of the ground facilities. The structure of the ground facilities is relatively complicated, which is not conducive to the user's use and maintenance; at the same time, the vehicle will inevitably swing from side to side when running on the track, and the contact wheels used in the above application either cannot be compatible with Contact with the inclined surface of the door, or the compression amount is too large, and the lock pin is bent. In both cases, the "secondary locking function" cannot be effectively realized.

Embodiment 1

[0050] Such as image 3 , 4 As shown, the secondary locking device for the bottom door of the railway funnel described in this embodiment includes a plate hook 1 , a plate hook mounting pin 2 , a tension spring 3 , a spring seat 4 , and a bottom door hanging pin 5 . It should be noted that although the example shown in this embodiment is a plate hook, it can be understood that the plate hook may not be used, and the technical problem of the present invention can also be solved by using other shaped hook components.

[0051] Such as Figure 5 As shown, the plate hook 1 is a lever type, including a guide surface 11, a locking groove 12, a mounting pin hole 13, and a tension spring mounting hole 14. The guide surface 11 is used to guide the hanging pin 5 of the bottom door to enter the locking groove 12, and the locking groove 12 is used to cooperate with the hanging pin 5 of the bottom door to ensure that the hanging pin 5 of the bottom door will not come off all the time in t...

Embodiment 2

[0180] Such as Figure 13 , 14 As shown, this program is made up of spring device 201, plate hook 202, plate hook mounting pin 203, spring device mounting seat 204, hanging pin 205, etc. The spring device 201 adopts a compression spring, and the plate hook 202 adopts a locking groove to be arranged oppositely. see Figure 13 and Figure 14 , the basic working principle, working steps, basic structure, force analysis, calculation method, etc. of the second embodiment are the same as those of the first embodiment. The main difference is that the installation method of the plate hook is different, and the locking groove is changed from the opposite arrangement to the opposite arrangement; the spring used to balance the force exerted by the bottom door on the plate hook is changed from a tension spring to a compression spring, and the installation method of the spring , The position of the hinge point of the mechanism, the trajectory of the movement, the shape of the plate hoo...

Embodiment 3

[0241] see Figure 26 , The secondary locking device of this embodiment includes a spring seat 301 , a tension spring 302 , a plate hook 303 , a plate hook installation pin 304 , and a bottom door hanging pin 305 . The plate hooks 303 are arranged oppositely with locking grooves. The force exerted by the bottom door on the plate hook 303 is balanced by the stretching force of the tension spring to keep the bottom door locked reliably.

[0242] Compared with Embodiment 1, this scheme has the same basic working principle, working steps, basic structure, force analysis, calculation method, etc. The main difference is that the plate hooks are installed in different ways, and the locking grooves are arranged from opposite to opposite. , the installation position of the tension spring used to balance the bottom door is changed from the inner side to the outer side, and the hinge point position, movement track, and shape of the plate hook of the mechanism also change accordingly.

Abstract

The invention relates to a secondary locking device for a hopper car bottom gate and a hopper car. The secondary locking device is used for the secondary locking of the bottom gate of a railway hopper car; the railway hopper car comprises a bottom gate and a primary locking device; the secondary locking device comprises a hook component; the hook component is mounted on a car body except the bottom gate through a pivot and can pivotally rotate along a car body; the first side of the hook component comprises a guide part and a locking part; the locking component is suitable for matching with the hopper car bottom gate in a locking manner to exert upward lifting force on the bottom gate, and the guide component is suitable for guiding the hook component and the hopper car bottom to be changed into a locking state from a releasing state; one end of a spring unit is connected with the second side of the hook component; the second side and the first side are respectively located on the two sides of the pivot; the other end of the spring unit is connected with the other car body part except the bottom gate and used for exerting force on the hook component. By adopting the above mode, secondary locking is realized, and the safety of the hopper car is improved.

Description

technical field [0001] The invention relates to a secondary locking device for a bottom door of a hopper car and a hopper car, belonging to the technical field of railway vehicles. Background technique [0002] The bottom door opening and closing mechanism of the railway bottom door hopper car for loading ore, coal and other goods usually adopts a mechanical linkage transmission mechanism. When the vehicle is in operation, the bottom door is located at the bottom of the compartment to bear the weight of the cargo. If the bottom door of the vehicle is opened during operation, the goods will be dumped on the line, causing major safety accidents such as derailment or tipping of the vehicle. Therefore, in order to ensure the safe operation of the vehicle, the bottom door must be provided with a reliable self-locking method or device to ensure that the bottom door is locked and will not automatically open during the operation of the vehicle. [0003] At present, the bottom door...
